Description

  The present invention relates to a temporary scaffold used indoors and outdoors in construction sites such as construction sites and civil engineering sites.

  Temporary scaffolds at construction sites include framework scaffolds and wedge-tight scaffolds used when building and housing are implemented, and system support works (also called formwork support works) made up of tightly structured structures. It is one mode of a temporary scaffold.

  The frame scaffolding is constructed by standing up multiple parallel building frames of H shape or torii shape, etc. composed of vertical pillars (also called building materials) and horizontal rails (also called horizontal materials) in parallel at appropriate intervals. After building the frame made of building frame and brace material by connecting the vertical columns facing each other with the brace material, a cloth frame with a floor (the cloth plate is also placed between the horizontal beams facing each other between the building frames. Is used as a work floor, a passage, a stage, or the like. In addition, a brace material may be connected for every step and may connect several steps at once. Here, pipes made of steel, aluminum, or the like are often used for the vertical columns, horizontal bars, brace materials, and the like.

  Next, the wedge-binding scaffold is a frame-shaped vertical assembly that is assembled from a support member having a connection fitting such as a frame on the side surface and a horizontal connecting material (a short connecting material may be particularly referred to as an arm wood). After constructing a frame consisting of a frame-shaped vertical surface and a brace material by connecting a plurality of surfaces in parallel at appropriate intervals and connecting the strut members facing each other between the vertical surfaces with a brace material, the vertical surface It is a one-stage or multi-stage scaffolding in which a cloth frame with a floor is bridged between connecting materials facing each other, and is used as a work floor, a passage, a stage, and the like. In addition, a brace material may be connected for every step and may connect several steps at once. Here, pipes made of steel or aluminum are often used for the support members, the connecting material, the brace material, and the like.

  In addition, the wedge-binding scaffold is composed of strut members facing each other between the vertical surfaces, instead of connecting the strut members facing each other between the strut members and the frame-shaped vertical surfaces assembled from the connecting members in the horizontal direction. It is also possible to construct a frame made up of a frame-shaped vertical surface and a connecting material by connecting them with another horizontal connecting material. That is, the frame is formed by orthogonalizing the installation direction of the frame using two types of the first binder located in the frame-shaped vertical plane and the second binder connecting the vertical planes of the frame shape. It can also be constructed. Here, the length of the first connecting member in the horizontal direction in the vertical plane and the length of the second connecting member that connects the vertical planes in the horizontal direction depend on the horizontal distance between the respective support members. Therefore, there are a case where two types of binder materials are used, and a case where a binder material having the same length is used.

  Furthermore, the wedge-binding scaffold has a brace material connecting the strut members facing each other between the strut members and the frame-shaped vertical surfaces assembled from the connecting members in the horizontal direction, and struts facing each other between the vertical surfaces. It is also possible to construct a frame made of a frame-shaped vertical surface, a connecting material, and a brace material by connecting the members with another horizontal connecting material. That is, the frame is formed by orthogonalizing the installation direction of the frame using two types of the first binder located in the frame-shaped vertical plane and the second binder connecting the vertical planes of the frame shape. Once constructed, the connection of the frame can be further reinforced with brace material. For the same reason as described above, there are a case where two types of binder materials are used, and a case where a binder material having the same length is used.

  Next, the system support is a scaffold often used when constructing a concrete structure or the like. It is a frame assembled from the ground or the floor surface, and is used as a scaffold by appropriately laying a cloth frame with a floor on it. That is, a plurality of frame-shaped vertical surfaces assembled from support members having connecting metal fittings on the side surfaces and horizontal connecting members are erected in parallel at appropriate intervals, and another horizontal member is disposed between the vertical support members facing each other between the vertical surfaces. A frame consisting of a frame-shaped vertical surface and a connecting material by connecting with direction connecting materials, and one or more floored cloth frames are horizontally placed between the connecting materials facing each other between the frame-shaped vertical surfaces It becomes a temporary scaffold used as a work floor, a passage, a stage, etc. That is, the frame is formed by orthogonalizing the installation direction of the frame using two types of the first binder located in the frame-shaped vertical plane and the second binder connecting the vertical planes of the frame shape. Is building. Here, the length of the first connecting member in the horizontal direction in the vertical plane and the length of the second connecting member that connects the vertical planes in the horizontal direction depend on the horizontal distance between the respective support members. Therefore, there are a case where two types of binder materials are used, and a case where a binder material having the same length is used.

  In addition to connecting the strut members facing each other between the strut members and the frame-shaped vertical surfaces assembled from the first strut members in the horizontal direction with the second strut members, By connecting the strut members facing each other with a brace material, it is also possible to construct a frame made up of a frame-shaped vertical surface, a connecting material, and a brace material. That is, the frame is formed by orthogonalizing the installation direction of the frame using two types of the first binder located in the frame-shaped vertical plane and the second binder connecting the vertical planes of the frame shape. Once constructed, the connection of the frame is further strengthened by brace material. For the same reason as described above, there are a case where two types of binder materials are used, and a case where a binder material having the same length is used. In addition, a brace material may be connected for every step and may connect several steps at once. Here, pipes made of steel or aluminum are often used for the support members, the connecting material, the brace material, and the like.

  Therefore, the structure of the system support work is the frame shape by connecting the opposite strut members with the second connecting material between the vertical members of the frame shape assembled from the supporting members and the first connecting material in the horizontal direction. This is substantially the same as the structure of a wedge-tight scaffold when a frame made of a vertical surface and a connecting material is constructed.

  As described above, a temporary scaffold composed of one or more stages is assembled. And the number of steps can be counted by the number of steps of the cloth frame with a floor to be bridged, and is determined depending on the height of the temporary scaffold to be assembled. Note that when assembling a temporary scaffold having a plurality of stages of cloth frames with a floor, the frames may be assembled one by one, or a plurality of frames may be assembled all at once.

  For example, in a wedge-tight scaffold or system support, a plurality of frame-shaped vertical surfaces that are assembled by connecting horizontal strut members with connecting brackets on the side surfaces in parallel at appropriate intervals. When connecting the strut members facing each other between the vertical surfaces with a horizontal connecting material, construct a one-step frame by connecting the connecting materials only on the same plane, and then oppose the vertical surfaces. One or more floored cloth frames are horizontally bridged between the connecting materials to form a one-stage scaffolding, and then a separately prepared strut member is added on the strut members constituting the scaffold. By repeating the above operation, the next stage scaffold can be assembled in sequence.

  Alternatively, a plurality of vertical surfaces having a plurality of frame shapes that are assembled from a plurality of horizontal connecting members and a column formed by vertically connecting column members having connecting brackets on the side surfaces are arranged in parallel at appropriate intervals. After constructing a multi-frame framework consisting of multiple frame-shaped vertical surfaces and horizontal connection materials by connecting multiple strut members facing each other with horizontal connection materials, Thus, a plurality of temporary scaffolds can be formed at a time by horizontally laying one or a plurality of floor-attached cloth frames between the respective connecting members facing each other.

  In addition, in the wedge-tightened scaffold or system support work, as the connection fitting provided on the side surface of the column member, a plurality of pieces provided on the side surface of the column member, a flange provided annularly on the side surface of the column member, or the like is used. Can do. And the wedge metal fitting provided in the edge part of a connecting member can be attached to connection metal fittings, such as a top and a flange, and can be fastened with a wedge.

  FIG. 1 shows an example of a wedge-tight scaffold. (a) is a front view of a wedge-binding scaffold, (b) is an enlarged view of the periphery of the top indicated by a circle in (a), and (c) is a right side view of the wedge-binding scaffold.

Here, three support columns 1 of the wedge-binding scaffold are erected on the building 14 side and on the opposite side. Each strut 1 is formed by adding a strut member 3 having a plurality of tops 4 on its side surface in the vertical direction via a tenon material (not shown). Between the building side and the supporting column 1 on the opposite side, a connecting member 2 is connected in the horizontal direction one above the other via a frame 4 and is fastened with a wedge (not shown) to form a frame shape. The vertical plane is assembled. Further, between the vertical planes, a brace member 21 is diagonally attached via a frame 4 between support members 3 facing on the opposite side of the building, and is fastened with a wedge (not shown) to form a frame shape. A frame consisting of the vertical plane and brace material is constructed. Here, in order to ensure the safety of workers, a handrail member 20 is further attached between the same support members 3 via the tops 4 and fastened with wedges. After that, the first-stage scaffolding is formed by bridging one or two parallel cloth frames 9 between the connecting members 2 facing each other. In addition, you may install a brace material and a handrail material also in the building side.

The second-stage scaffold is formed in the same manner as the first-stage scaffold, if necessary. A support member 3 prepared separately on the upper end of the support member 3 of the first stage scaffold is added in the vertical direction via a tenon material (not shown), and then the connecting material 2, the brace material 21, and the handrail member 20 The scaffold constituent members are attached via the tops 4, and these scaffold constituent members are fastened together with wedges (not shown) at the top 4, and then the floor-attached cloth frames 9 are respectively placed between the facing connecting members 2. A second-stage scaffold is formed by spanning two or more sheets in parallel. By repeating this sequentially, a multi-stage scaffold is assembled.

  FIG. 2 is a front view showing an example of the system support work, and FIG. 3 is a right side view of the system support work of FIG. 4 is a cross-sectional plan view taken along line AA in FIG.

  In this example, the system support work 100 is installed at a height of several m to several tens m from the ground so as to support the lower surface of the formwork 102 above the concrete structure (slab) 101.

  This system support work 100 is a framework constructed by arranging a plurality of support columns 1 in a matrix at predetermined intervals, and connecting adjacent support columns 1 in a horizontal two direction with a plurality of connecting members 2. Then, it is used as a scaffold by appropriately laying a cloth frame with a floor on it. That is, the first horizontal connecting member between the respective supporting columns 1 formed by adding the supporting column members 3 having the plurality of tops 4 on the side surfaces in the vertical direction via the tenon material (not shown). By connecting a plurality of vertical surfaces in the horizontal direction with a second connecting member 2 installed in a direction orthogonal to the first connecting member 2 between the vertical surfaces assembled by connecting two members and the vertical surfaces. A framework is built. The lower end of each column 1 is supported by a jack base 5. A large jack jack 6 is attached to the upper end of each strut 1, and a plurality of large pull materials 7 are placed on the large jack jack 6. Further, a plurality of joists 8 are placed on the plurality of large joists 7 and the formwork 102 is placed on the plurality of joists 8 so as to be orthogonal to the large joists 7. In addition, you may install a brace material and a handrail material between the support | pillar 1 suitably.

  Four frames 4 are formed in a cross shape at predetermined intervals on the side surface of each column 1 (see FIG. 4). The connecting material 2 is connected to the frame 4 via a wedge metal piece joined to both ends of the connecting material 2 and is fastened by a wedge 2a. Here, the connecting material 2 is not attached to the central piece 4 of each support member 3, but the connecting material 2 may be attached to the central piece 4 of each support member 3.

  And as shown in FIG. 4, the cloth frame 9 with a floor is bridged horizontally between the connecting materials 2 which oppose. Similarly, a scaffold for use as a work floor, a passage, a stage, or the like can be formed where necessary by laying the cloth frame 9 with a floor horizontally between the other facing connecting members 2. . Here, one scaffolding frame 9 is horizontally spanned between the opposing first tethers 2 to form one scaffold, which is used as a work floor, a passage or a stage. The

  As described above, in the wedge-tight scaffold and the system support work, the support members having the connection brackets such as frames are provided on the side surfaces, and the support members can be connected in the horizontal direction by the connecting material.

  The connecting material used here is made of steel or aluminum pipes with a wedge fitting joined to both ends of the pipe by welding or the like. By being fastened together, it can be used fixed to the column member.

  FIG. 5 is a front view of an example (conventional example) of a connecting material used in a wedge-tight scaffold or system support work.

  This connecting material 2 is formed by joining a wedge metal fitting 2b to both ends of a horizontal member 31 made of a pipe made of steel, aluminum or the like by welding or the like, and its total length is adjusted to the interval between the support members 3. . The hook member 2b of the connecting member 2 is hooked on a connecting metal member such as the top 4 provided on the side surface of the column member 3 and then fastened by the wedge 2a, whereby the column members 3 can be connected and fixed.

  Regarding this binder, in order to increase the strength of the binder itself, or to firmly connect the binder to the support member, a cane is provided obliquely from the lower part of the binder to the support. Has been proposed (see Patent Document 1 and Patent Document 2).

  FIG. 6 is a front view of an example (conventional example) of a connecting material with a cane disclosed in Patent Document 1. FIG.

  In addition to joining the wedge metal fittings 2b to both ends of a horizontal member 31 made of a pipe made of steel, aluminum or the like by welding or the like, the connecting member 30 with a cane is a horizontal member for increasing the strength of the connecting member itself. Two wands 32 that support 31 from diagonally below are provided. The lower end portion of each cane 32 has a semi-cylindrical vertical plate 33 having an inner diameter substantially the same as the outer diameter of the column member 3, and the vertical plate 33 is pressed against the side surface of the column member 3. It has been. Further, in order to prevent deformation of the connecting member 30 with the cane, one bundle member 34 is installed vertically from the vicinity of the left and right ends of the horizontal member 31, and connects with the respective canes 32. Thus, each wand 32 is supported from above. The hook metal fittings 2b joined to both ends of the horizontal member 31 of the connecting material are hooked on connecting metal fittings such as the tops 4 provided on the side surfaces of the post member 3, respectively, and then fastened by the wedges 2a, whereby the post member 4 It is possible to connect and fix between.

  FIG. 7 is a front view of an example (conventional example) of a connecting material with a cane disclosed in Patent Document 2. FIG.

  In addition to joining the wedge metal fittings 2b to both ends of a horizontal member 31 made of steel, aluminum, or the like, the tie member 30 with the cane is joined to the two members that support the horizontal member 31 obliquely from below. A cane 32 is provided. Moreover, the wedge metal fitting 30b is joined also to the lower end part of each cane 32 by welding etc. FIG. Further, in order to prevent deformation of the connecting member 31 with the cane, one bundle member 34 is installed vertically from the vicinity of the left and right ends of the horizontal member 31, and is connected to the respective canes 32. Thus, each wand 32 is supported from above. After the wedge metal fitting 2b joined to both ends of the horizontal member 31 of this connecting material is hooked on a connecting metal fitting such as the top 4 provided on the side surface of the column member 3, the wedge metal 2b is fastened by the wedge 2a. After hooking the wedge metal fitting 30b provided at the lower end portion of the frame member 4 to the connecting metal fitting such as the top 4 provided on the side surface of the column member 3, the wedge member 30a is tightened to firmly connect the binder material to the column member 3. Can be connected and fixed.

  Thus, the strength of the connecting material itself can be increased by providing the staff with the connecting material in which the wedge metal fittings are joined to both ends of the horizontal member made of a pipe made of steel or aluminum. In particular, since the tie material with a wand formed by joining a wedge metal fitting to the lower end of the wand has a great binding effect due to the wedge, the tie material can be firmly connected and fixed to the support column.

Japanese Patent Laid-Open No. 06-280382 Japanese Patent Application Laid-Open No. 06-299691

  However, when assembling these tie members with a cane, it is necessary to tie the two or four wedge metal fittings provided on the left and right ends to the connecting metal fitting on the side surface of the column member with the wedges. However, since the wedge part joined to both ends of the horizontal member exists at a high place, there is a problem that it is difficult for a worker to reach the hand, so that it is difficult to tighten the wedge. In addition, in the tie material with a wand formed by joining the wedge metal fittings to the lower ends of the left and right wands, there are four wedge metal fittings.

  FIGS. 8 and 9 are examples of binding work by wedges when attaching the tie member with the wand shown in FIG. 7 between the strut members.

  In this tie member 30 with a cane, since the wedge metal fitting 2b joined to both ends of the horizontal member 31 is present at a high place, it is difficult for an operator to reach the hand during tightening work with the wedge 2a. Not only is the tightening operation to be driven difficult, but also there are four wedge metal fittings 2b and 30b, so that it can be seen that there is a problem that the tightening operation of driving the wedges 2a and 30a with the hammer 36 is troublesome.

  The present invention has been made to solve the above-described problems, and can facilitate and reduce the connection work with the support member, and can be firmly connected to the support member. An object is to provide a temporary scaffolding that incorporates a tether that can be used.

  The present inventors have made various studies in order to solve the above problems. As a result, the following findings (a) to (h) were obtained.

  (a) Among the temporary scaffolds, the frame scaffolds use H-shaped or torii-shaped building frames in which vertical columns and crosspieces are integrated, so they are heavy and bulky. Have. In addition, as will be described later, for scaffolds installed at locations that hit the corner of the building, a wife's face is formed in front of or behind the work floor or passageway. Since it cannot be performed and a gap is generated, there is a problem in terms of safety of workers.

On the other hand, in the wedge-tight scaffolding and system support work, the strut member and the connecting material are separate members and can be assembled on site. And since it is lightweight and does not become bulky, it is easy to carry. However, since the connecting portion of the support member and the connecting material is not integral, it is necessary to increase its strength. As a connecting material that can be firmly connected to the support member, a basic structure comprising a horizontal member made of a pipe made of steel or aluminum and two canes that support the horizontal member obliquely from below. It is desirable to adopt a structure that can be firmly connected to the left and right support members at a total of four locations, both ends of the horizontal member and the lower ends of the two canes. Therefore, in order to firmly connect to the column member, as shown in FIG. 6, a structure in which only a semi-cylindrical vertical plate is provided and this vertical plate is pressed against the side surface of the column is used. Instead, as shown in FIG. 7, it is preferable to provide a wedge metal fitting at the lower ends of the two canes so that all four places can be fastened with wedges. However, as shown in FIG. 7, the tie member with the wand shown in FIG. 7 has a wedge metal fitting joined to both ends of the horizontal member at a high place. This is not only difficult to tighten, but also has a total of four wedge metal fittings, and there is a problem that it takes time and labor for the wedge.

  (b) The inventors of the present invention have studied a method that can firmly connect the tie member with the cane to the support member even if the four parts are not fastened with wedges. As a result, instead of fastening all four points on the left and right ends of the horizontal member of the bridging member with the cane and the lower ends of the two left and right canes with two wedges, two places on the both ends of the horizontal member. In this case, instead of binding with a wedge, it has been thought that the tie member with the cane can be firmly connected to the left and right support members by hooking to the support members.

  That is, out of the four connecting means of the connecting material with the cane, the two left and right portions of the both ends of the horizontal member present at the high place are connected by hooking to the column member instead of being fastened with the wedge, The two lower ends of the left and right canes are fastened together using wedges. Here, examples of the latching method between the end of the horizontal member and the support member include a combination of a button pin and a notch having a shape that can be latched on the button pin. Since the button pin is composed of a button part (large diameter) and a mounting shaft (small diameter), if the width of the notch is smaller than the outer diameter of the button part and larger than the outer diameter of the mounting shaft, the end of the horizontal member The part can be hooked on the column member, and the end of the horizontal member is difficult to come off from the column member after hooking. In addition, although a button pin will be provided in either the side surface of a support | pillar member, or the edge part of a horizontal member, welding, a screw, etc. are employable as the joining means.

  With such a latching structure, the wedge metal fitting for binding the wedge can be halved to only the two lower end portions of the left and right canes, and the height at the two left and right ends of the horizontal member can be reduced. This eliminates the need for a wedge work at the place. Therefore, it is possible to facilitate and reduce the binding work by the wedge.

  (c) When a combination of a button pin and a notch having a shape that can be hooked to the button pin is used as a hooking means between the end of the horizontal member and the column member, the button pin and the button pin are hooked. Specifically, the combination of notches having a shape that can be formed is the following (i) or (ii).

  (i) A button pin is provided on the side surface of the support member, and on the other hand, an end plate having a downward cutout is provided at the end of the horizontal member, and the end of the horizontal member is moved downward from above. Fit the downward notch on the button pin. In the case of a button pin comprising a button part and its mounting shaft, the width of the downward notch provided on this end plate is larger than the outer diameter of the mounting shaft and smaller than the outer diameter of the button part. To do. Here, since it is necessary to move the button portion simultaneously with the mounting shaft, an opening enough to accommodate the button portion is provided below the end plate or below the end portion of the horizontal member. As described above, the button pin can be joined to the side surface of the support member by welding or a screw. Considering the labor of joining, it is preferable to join with screws such as blind nuts. In addition, the horizontal member that is hooked on the side surface of the support member is not limited to one direction, but may be 2 to 4 directions on the periphery of the support member. The number of button pins to be installed is 1 to 4. When a plurality of button pins are joined to the circumference of the side surface of the support member by screws, it is preferable to use a blind nut.

  (ii) An upward notch is provided on the side of the support member, while a button pin is provided at the end of the horizontal member, and the button pin is moved upward by moving the end of the horizontal member downward from above. Fit into the notch. Here, the width of the upward notch provided on the side surface of the support member is larger than the outer diameter of the button pin mounting shaft and smaller than the outer diameter of the button portion. The upward notch may be formed by attaching a thin frame on the side surface of the column and providing an upward notch on the front wall of the thin frame. Here, the thin frame may have a shape with a missing bottom surface. As described above, the button pin can be joined to the end of the horizontal member by welding or a screw. Considering the labor of joining, it is preferable to join with screws such as blind nuts.

  As a result, as shown in (i) above, the end of the horizontal member is moved downward from above, and the button pin provided on the side surface of the column member is moved downward to the end plate provided on the end of the horizontal member. By engaging the notch portion, when the end portion of the horizontal member and the support member are connected, the connection is not released unless the end portion of the horizontal member is moved upward. In other words, since the horizontal member is a part of the connecting material with the cane, the connection is not released unless the connecting material with the cane is moved upward. Note that the end of the horizontal member is rotatable about the button pin provided on the side surface of the support member, so that it is not always necessary to move the end of the horizontal member from above, but from the side or from below. Even if it is made to do, the edge part of a horizontal member can be hooked on a button pin.

  Further, as described in (ii) above, the end of the horizontal member is moved downward from above, and the button pin provided on the end of the horizontal member is hooked on the upward notch provided on the side surface of the column member. By stopping, even when the end of the horizontal member and the support member are connected, the connection is not released unless the end of the horizontal member is moved upward. In other words, since the horizontal member is a part of the connecting material with the cane, the connection is not released unless the connecting material with the cane is moved upward. Since the end of the horizontal member is rotatable about the upward notch provided on the side surface of the column member as a rotation axis, it is not always necessary to move the end of the horizontal member from above. Even when moved from below, the end of the horizontal member can be hooked on the button pin.

  Furthermore, the wedge metal fittings provided at the lower ends of the left and right wands of the tie material with the wand have a shape that can be held by sandwiching the connecting members such as the top and the flange of the support member from above and below, for example, a C-shape when viewed from the front It is preferable to have. When the wedge metal fitting has such a shape, once the connecting material with the cane is connected to the support member, even if the connecting material with the cane tries to move up and down, it will hit the connecting member of the support member, It can prevent that a binder with a cane comes off from a support | pillar member.

  (d) As a modification of the above (ii), instead of providing a button pin at the end of the horizontal member as a latching means, a circular end plate having an outer diameter larger than the outer diameter of the horizontal member may be provided. Good. That is, an upward notch portion having a width smaller than the outer diameter of the circular end plate is provided on the side surface of the column member, and the circular end plate provided at the end portion of the horizontal member is moved downward from above. This button pin is fitted into the upward cutout.

  In this way, the end plate of the horizontal member is moved downward from above, and the circular end plate provided on the end of the horizontal member is hooked on the upward notch provided on the side surface of the column member. Accordingly, even when the circular end plate provided at the end of the horizontal member is connected to the support member, the connection is not released unless the end of the horizontal member is moved upward. In other words, since the horizontal member is a part of the connecting material with the cane, the connection is not released unless the connecting material with the cane is moved upward. Since the end of the horizontal member is rotatable about the upward notch provided on the side surface of the column member as a rotation axis, it is not always necessary to move the end of the horizontal member from above. Even when moved from below, the end of the horizontal member can be hooked on the button pin.

  (e) As described above, the end portion of the horizontal member is rotatable about the button pin provided on the side surface of the column member or the upward cutout portion as the rotation axis. That is, the tie material with the cane is rotatable about the button pin provided on the side surface of the support member or the upward notch as the rotation axis. Therefore, after the end of the horizontal member and the support member are connected, the wedge fitting provided at the lower end of the cane is fastened to the connection member of the support member with the wedge, and the wedge fitting and the support member at the lower end of the support member are connected. It is possible to easily align the connecting metal fittings.

  (f) Next, in the wedge-tight scaffolding and system support work, a handrail member is further provided between the strut members facing each other between the vertical surfaces to prevent the worker from falling from the work floor, passage, stage, etc. Can be provided. When assembling the scaffolding, this handrail member can be attached to the handrail member via the connecting bracket between the strut members from the floor cloth frame after the floor-mounted cloth frame is laid. In view of the safety of personnel, it is preferable to use a leading handrail member that can be attached in advance. This is because when the leading handrail member is used, when the cloth frame with a floor is horizontally stretched and used for a work floor, a passage, a stage, or the like, the handrail members are already installed on both sides of the scaffold. The front handrail member can be rotated and fixed upward after the worker attaches the upper handrail member in advance from the lower scaffold when assembling the scaffold, and conversely the worker when disassembling the scaffold. Can be removed from the lower scaffold after rotating the upper handrail downward.

  In all cases, when forming a scaffold by laying a cloth frame with a floor, it is integrated with the handrail member as a brace material that connects the strut members facing each other between vertical surfaces to prevent the worker from falling. It is also possible to use a brace integrated handrail frame. Moreover, it is also possible to use a tie material with a handrail frame formed by joining the handrail member to a rotatable horizontal member of the tie material as a tie material for connecting the strut members facing each other between the vertical surfaces. At this time, the work efficiency of the assembly can be improved by adding the function of the handrail frame to the brace material. In other words, if a brace-integrated handrail frame integrated with a handrail member is used, the brace member can be connected with a single brace-integrated handrail frame, and the work of attaching the brace material and the handrail material is performed once. You can do it.

  Next, when connecting the strut members facing each other between the vertical surfaces of the frame shape with a connecting material, the preceding handrail frame is joined to the horizontal member constituting the connecting material, and the function of the handrail frame is connected to the connecting material. As a result, assembly work efficiency can be improved. In other words, if you use a leading handrail frame-integrated connecting material that joins the preceding handrail frame between the strut members facing each other between the vertical surfaces of the frame shape, you can install the connecting material and the handrail material at once. it can. This leading handrail frame-integrated connecting material can be rotated around the axis of the horizontal member that forms the connecting material, so when assembling the scaffold, the worker attaches the upper handrail member in advance from the lower scaffold. Then, it can be rotated and fixed upward, and on the contrary, when dismantling the scaffold, an operator can rotate the upper handrail downward from the lower scaffold and then remove it.

  (g) In addition, for scaffolds installed at locations that hit the corners of buildings, wife surfaces are formed in front of or behind work floors and passages, but in wedge binding scaffolds and system support works, frames are also continuous in the corners. As a result, the gap does not occur. Further, a handrail member can be provided between the support members on the wife surface to prevent the worker from falling from the wife surface. In this case, the worker can attach the handrail member between the strut members on the wife's face from the floor-attached cloth frame after the floor-attached cloth frame is bridged. It is preferable to use a leading handrail member that can be attached to the front. This is because when the leading handrail member is used, when the cloth frame with a floor is horizontally stretched and used as a work floor or a worker's passage, the handrail member is already installed on the scaffold surface. In this case, it is preferable from the viewpoint of work efficiency that the leading handrail frame is incorporated in the connecting material for connecting the supporting members on the end face.

  Hereinafter, a temporary scaffold according to the present invention will be described based on examples. In addition, this invention is not limited to an Example.

  FIG. 10 is an example of a connecting material with a cane used in the temporary scaffolding according to the present invention. (a) is a front view. (b)-(d) is the enlarged view of the A section, among which (b) is a left side view, (c) is a front view, and (d) is a bottom view.

  This tie member 30 with a cane is composed of a horizontal member 31 made of a tube made of steel or aluminum, and two cane 32 that support the horizontal member 31 from obliquely below. An end plate 40 having a downward cutout 40a is joined to each end of the horizontal member 31 by welding or the like, and an opening 31a is provided below the end of the horizontal member 31. By hooking the end of the horizontal member 31 to the support member, the end of the horizontal member 31 can be connected to the support member. On the other hand, a wedge metal fitting 30b is joined to the lower end of the cane 32 by welding or the like. After the wedge metal fitting 30b is hooked on a connecting metal piece such as a frame provided on the side surface of the column member, the wedge 30a is attached. By driving in, the lower end of the cane 32 can be fastened to the support member. Here, since the wedge metal fitting 30b provided at the lower end of the wand 32 has a C shape when viewed from the front, the wedge metal fitting 30b sandwiches the connection metal fitting such as a frame provided on the side surface of the support member from above and below. You can hold in. Therefore, once the connecting member 30 with the cane is connected to the support member, even if the connecting member 30 with the cane moves up and down, the connecting member 30 such as the top of the support member collides with the connecting member 30 such as the top member. Can be prevented from coming off from the support member. In order to prevent deformation of the connecting member 30 with the cane, one bundle member 34 is installed vertically from the vicinity of the left and right ends of the horizontal member 31, and the respective canes 32 are connected to each other. The wand 32 is supported from above.

  Here, the width of the downward cutout portion 40a provided on the end plate 40 joined to the end portion of the horizontal member 31 is smaller than the outer diameter of the button portion of the button pin provided on the column member to be connected. And larger than the outer diameter of the mounting shaft. On the other hand, the width of the opening 31a provided at the lower part of the end of the horizontal member 31 is larger than the outer diameter of the button portion of the button pin provided in the column member to be connected and the outer diameter of the mounting shaft. Greater than. Therefore, the end portion of the horizontal member 31 can be hooked to the column member, and the end portion of the horizontal member 31 is not easily detached from the column member after the latching.

  FIG. 11 shows four examples of button pins provided on support members to be connected. In the four examples (a) to (d), a front view is shown on the left side and a right side view is shown on the right side.

  Each button pin 41 includes a large-diameter button portion 41a and a small-diameter attachment shaft 41b. The attachment portion 41b is attached to the side surface of the column member 3 with the button portion 41a as an outer surface. Any joining means for attaching the button pin 41 to the side surface of the column member 3 is by welding. The outer diameter of the button portion 41 a is smaller than the width of the opening portion 31 a provided at the lower portion of the end portion of the horizontal member 31, and is provided on the end plate 40 joined to the end portion of the horizontal member 31. It is larger than the width of the downward cutout 40a. The outer diameter of the mounting portion 41 b is smaller than the width of the opening portion 31 a provided at the lower portion of the end portion of the horizontal member 31, and is provided on the end plate 40 joined to the end portion of the horizontal member 31. It is smaller than the width of the downward cutout 40a.

  (A) of FIG. 11 has a truncated cone shape with an inclined portion on the back surface of the button portion 41a, and the mounting shaft 41b has a cylindrical shape. In (b), both the button portion 41a and the mounting shaft 41b are cylindrical. (c) is a modification of (b), and the attachment shaft 41b is attached to the side surface of the column member 3 via a columnar column fixing member 41c. (d) is a modification of (a). Since the attachment shaft 41b penetrates the support | pillar member 3 and can be attached by welding the attachment shaft 41b on the opposite side to the attachment side of a button pin, it can fix firmly.

  FIG. 12 shows another example of a button pin provided on a column member to be connected and an example of its joined state. (a) is a front view and right side view of the button pin, (b) is a sectional view (front view) and right side view of the washer, and (c) is a state in which the button pin is joined to the hole on the side surface of the column member. FIG. 5D is a top view and FIG. 4D is a cross-sectional view (top view) of the joint portion in a state where the button pin is joined to the hole on the side surface of the support member.

  As shown in FIG. 12 (a), the button pin 41 includes a button portion 41a having a truncated cone shape with an inclined portion on the back surface, a cylindrical mounting shaft 41b, and a navel having a male screw cut on the outer surface. It consists of a bolt 41d.

  The navel bolt 41d is screwed into a blind nut 51 previously inserted into a hole 52 formed in the side surface of the support member 3 through a navel washer 50 shown in FIG. As shown in FIGS. 12C and 12D, the button pin 41 is joined to the support member 3.

  That is, after inserting the blind nut 51 having an internal thread cut into the hole 52 in a state of being inserted into a drive screw (not shown) at the tip of the tool, the blind nut 51 is inserted into the hole 52 by caulking. It fixes to 52. The button pin 41 can be joined to the column member 3 by screwing the navel bolt 41d into the fixed blind nut 51 via the navel washer 50. Therefore, labor can be saved compared to the joining work by welding.

  FIG. 13 shows a state in which the four button pins shown in FIG. 12 are joined on the circumference of the side surface of the column member to be connected. (a) is a top view, and (b) is a cross-sectional view (top view).

  The method of joining the button pin 41 to the support member 3 is as described above. Here, since the connecting members are connected in four directions, the number of button pins 41 to be installed on the circumference of the side surface of the column member 3 is four. However, even if the number of installed button pins 41 is four, the button pins are installed by screw joining using the blind nut 51, so that the other button pins do not get in the way during the installation operation.

  FIG. 14 shows a procedure for hooking the end of the horizontal member of the tie member with the cane of FIG. 10 to the button pin on the side surface of the column member of FIG. 11 (a). Here, (a) to (c) are front views, (d) is an AA arrow view, and (e) is a BB arrow view.

(a) is the position where the end of the horizontal member 31 of the tie material with the cane is aligned with the support member 3 provided with the button pin 41 on the side surface , and (b) is the end of the horizontal member on the button pin 41. (C) shows the state where the button plate 41 is hooked with the downward notch 40a on the end plate 40 (both are front views). ). And (d) is an AA arrow sectional view of (c), (e) is a BB arrow view of (d).

As described above, a downward opening 31a is formed at the end of the horizontal member 31 of the connecting member with the cane, and the end plate 40 provided at the lower portion of the end of the horizontal member 31 has a downward notch. A portion 40a is formed. Then, by moving the end portion of the horizontal member 31 from above to below, the button plate 41 can be hooked with the downward notch portion 40 a of the end plate 40. Since the width of the notch 40a and the outer diameter of the button pin 41a and the mounting shaft 41b of the button pin are in the relationship as described above, the button plate 41 once has a notch 40a facing downward on the end plate 40. It can be seen that the connection of the end portion of the horizontal member 31 to the column member 3 is not released unless the end portion of the horizontal member 31 is lifted upward.

  In addition, after the downward notch 40a of the end plate 40 is hooked on the button pin 41, the end plate 40 has play between the downward notch 40a and the button pin mounting shaft 41b. There is also play between the end plate 40 and the button part 41a of the button pin, so that the end part of the horizontal member rotates about the button pin mounting shaft 41b provided on the side surface of the support member. Be free.

  FIG. 15: shows the procedure at the time of connecting and fastening the whole binder with a cane of FIG. 10 to the side surface of a support | pillar member by (a)-(d) (right view). Here, for the sake of easy understanding, only the end plate 40 of the horizontal member of the binder with the cane and the wedge metal fitting 30b joined to the lower end of the cane 32 are illustrated.

  (a) shows the support | pillar member 3 which provides the button pin 41 in the upper part of a side surface, and provided the top 4 in the lower part. (b) shows the middle of moving the end of the horizontal member from the upper side to the button pin 41 on the side surface of the column member 3, and (c) shows the state where the downward notch 40 a is hooked on the button pin 41. (D) shows that the wedge 30a is driven after the wedge metal fitting 30b joined to the lower end of the wand 32 is hooked on the top 4 on the side surface of the column member 3.

  That is, in the operation of connecting the connecting member with the cane between the support members, first, the notches 40a of the end plates 40 of the horizontal members are hooked on the button pins 41 on the side surfaces of the left and right support members 3, respectively. Thereafter, the tie member with the cane is rotated about the button pin 41 as a rotation axis, and the lower ends of the left and right two canes 32 are respectively aligned with the tops 4 on the side surfaces of the left and right support members 3. A procedure is adopted in which 30a is fastened by driving into the wedge metal fitting 30b.

  FIG. 16 is an example of a tightening operation using wedges when attaching the tie member with the wand shown in FIG. 10 between the strut members.

  In this tie member 30 with a cane, no wedge metal fitting is provided at both ends of the horizontal member 31 present at a high place, and the wedge metal fitting 30b is provided at the lower end of the two canes that support the horizontal member 31 from obliquely below. They are only provided. Since the lower end of the cane exists in a low place where the worker can easily reach, the worker can easily perform the binding work of driving the wedge 30a with the hammer 36. In addition, since the wedge metal fitting 30b exists only in two places, the time for tightening work for driving the wedge 30a with the hammer 36 can be reduced. Further, since both ends of the horizontal member 31 are firmly attached to the column member 3 by the latching means, this cane is coupled with binding means by wedges at the lower ends of the two canes that support the horizontal member 31 from obliquely below. It can be seen that the connecting material 30 is firmly connected to the column member 3.

  FIG. 17 shows a state after the tie member 30 with the cane of FIG. 10 is connected to the side surface of the column member 3. FIG. 17 (a) is a front view, and FIG. 17 (b) is an arrow CC view. As shown in FIG. 17B, the wedge 30 a for driving into the wedge metal fitting 30 b can be accommodated in a wedge temporary receiving hole 34 a provided in the middle of the bundle 34.

  FIG. 18 is an example (perspective view) of a temporary scaffold in which the tie member 30 with the cane of FIG. 10 is incorporated. Here, a frame is constructed using the brace-integrated handrail frame 22 as a member for connecting the struts 1 facing each other between the vertical surfaces of the frame shape assembled from the struts 1 and the tie member 30 with the cane, And two cloth frames 9 with a floor are spanned horizontally between the connecting material 30 with a cane which opposes, respectively, and the scaffold is formed. Here, although the brace material integrated handrail frame 22 is provided on both sides of the scaffold, it can be installed only on the opposite side of the building.

  As described above, the temporary scaffolding incorporating the tie material with the cane is used as the tie material with the wand connected between the support members at the two places on both ends of the horizontal member even if the four parts are not fastened with wedges. The tie member with the cane can be firmly connected to the left and right support members by hooking to the support members instead of binding with wedges. Further, the operation of connecting the tie member with the cane between the support members is reduced and facilitated. Further, the connecting material with a cane according to the conventional example (see FIGS. 6 and 7) has a cloth frame with a floor spanned on the connecting material as a support column due to the presence of the wedge metal fittings provided at both ends of the horizontal member. Although it was not possible to lay down to the side of the member, in the example of the present invention, it is possible to spread the cloth frame with a floor to the side of the column member, so that an effect that a gap is not easily generated between the column member and the cloth frame with the floor There is.

  FIG. 19 is another example of a connecting material with a cane used in the temporary scaffolding according to the present invention. (a) is a front view. (b)-(d) is the enlarged view of the A section, among which (b) is a left side view, (c) is a front view, and (d) is a bottom view. FIG. 20 shows a state (front view) after the tie member 30 with the wand is connected to the side surface of the support member 3.

  This long tie material with a cane differs from the tie material with a cane of Example 1 only in that the horizontal member 31 is long. Therefore, similar to the tie material with the cane shown in the first embodiment, as the tie material with the wand connected between the support members, the four parts are not fastened with wedges at the two ends of the horizontal member. Since the binding material with the cane can be firmly connected to the left and right support members by hooking to the support members instead of binding with wedges, a temporary scaffold similar to that shown in FIG. 18 can be constructed. Further, the operation of connecting the tie member with the cane between the support members is reduced and facilitated. Further, the connecting material with a cane according to the conventional example (see FIGS. 6 and 7) has a cloth frame with a floor spanned on the connecting material as a support column due to the presence of the wedge metal fittings provided at both ends of the horizontal member. Although it was not possible to lay down to the side of the member, in the example of the present invention, it is possible to spread the cloth frame with a floor to the side of the column member, so that an effect that a gap is not easily generated between the column member and the cloth frame with the floor This is the same as in the first embodiment.

  FIG. 21 is another example of a connecting material with a cane used in the temporary scaffolding according to the present invention. (A) of FIG. 21 is a front view, (b) is an enlarged left side view of part A, and (c) is an enlarged front view of part A.

  This tie member 30 with a cane is composed of a horizontal member 31 made of a tube made of steel or aluminum, and two cane 32 that support the horizontal member 31 from obliquely below. A button pin 41 is joined to each of the end portions of the horizontal member 31 via an end plate 40, and the end portion of the horizontal member 31 is secured by hooking the end portion of the horizontal member 31 to the support member. It can be connected to a strut member. On the other hand, a wedge metal fitting 30b is joined to the lower end of the cane 32 by welding or the like. After the wedge metal fitting 30b is hooked on a connecting metal piece such as a frame provided on the side surface of the column member, the wedge 30a is attached. By driving in, the lower end of the cane 32 can be fastened to the support member. Here, since the wedge metal fitting 30b provided at the lower end of the wand 32 has a C shape when viewed from the front, the wedge metal fitting 30b sandwiches the connection metal fitting such as a frame provided on the side surface of the support member from above and below. You can hold in. Therefore, once the connecting member 30 with the cane is connected to the support member, even if the connecting member 30 with the cane moves up and down, the connecting member 30 such as the top of the support member collides with the connecting member 30 such as the top member. Can be prevented from coming off from the support member. In order to prevent deformation of the connecting member 30 with the cane, one bundle member 34 is installed vertically from the vicinity of the left and right ends of the horizontal member 31, and the respective canes 32 are connected to each other. The wand 32 is supported from above.

  Here, the button pin 41 includes a large-diameter button portion 41a and a small-diameter attachment shaft 41b, and is vertically attached to the end plate 40 joined to the end portion of the horizontal member 31. In addition, the outer diameter of the button part 41a is larger than the width | variety of the upward notch part provided in the front wall of the thin frame attached to the support | pillar member which should be connected. Further, the outer diameter of the mounting portion 41b is smaller than the width of the upward cutout portion. Therefore, the end portion of the horizontal member 31 can be hooked to the column member, and the end portion of the horizontal member 31 is not easily detached from the column member after the latching.

  The button pin attached to the end plate 40 joined to the end of the horizontal member 31 can be of the same shape as that shown in FIGS. Also, the button pin can be attached by welding or screwing in the same manner as in FIGS. Considering the labor of joining, it is preferable to join with screws such as blind nuts.

  FIG. 22 is an example of an upward notch provided in a support member to be connected. A front view is shown on the left side, and a right side view is shown on the right side.

  The upward notch 42 a is formed by attaching a thin frame 42 to the side surface of the column member 3 and providing a notch on the front wall of the thin frame 42.

  FIG. 23 is a front view showing a procedure for hooking the end portion of the horizontal member of the tie member with the cane in FIG. 21 to the upward notch on the side surface of the column member in FIG. 22.

(a) is the position where the end of the horizontal member 31 of the connecting member with the cane is aligned with the column member 3 provided with the thin frame 42 having the upward notch on the side surface , and (b) In the middle of moving the end of the horizontal member downward from the top to the thin frame 42, (c) hooks the button pin 41 at the end of the horizontal member 31 on the column member to the thin frame 42. However, each is shown.
