Description

  The present invention relates to a wall material mounting jig suitable for a work of mounting a wall material on a building, and a wall material construction method using the same.

  In general, steel buildings such as factories and warehouses have a metal wall material (also referred to as siding) formed in a corrugated shape from the outside of the torso to provide an exterior.

  When mounting such a wall material on site, first, a multi-stage scaffolding is extended in the horizontal direction on the outside of the torso according to the height of the wall material. And, the wall material temporarily placed on the roof of the building using a crane or on a dedicated rack, etc. is manually suspended using a rope one by one or between the trunk edge and the scaffolding using a crane. It is a method in which the wall material is screwed to the trunk edge after being aligned to the trunk edge while holding the four corners of the suspended wall material by four persons respectively (for example, (See Patent Document 1).

  As described above, when the wall material is attached by four people, it is difficult to align the wall material by simply supporting it from the left and right when the vertical length of the wall material is as long as 6 to 8 m. This is because it is necessary to support the wall material from all sides by dividing two people into the scaffolding.

JP 2007-113282 A

  However, the positioning of the wall material performed by four persons in this way requires the four persons to breathe together, which is labor intensive and has low work efficiency. In addition, when performing work using a plurality of upper and lower scaffolds, there is a risk that falling objects from the upper stage will hit the lower workers.

  An object of the present invention is to increase the safety of wall work attachment work and to obtain high work efficiency with a small number of hands.

  In order to solve the above-described problems, the present invention provides a wall material mounting jig used when mounting a wall material on a body edge of a building, and has a folded part that is hooked on the upper end of the wall material, A suspension fitting in which a bolt hole is formed to project the tip of the bolt in a direction opposite to the folding direction, and a plate-like member fixed to the suspension fitting in a state suspended from a wall member with a bolt and a nut. The flat member is formed by bending both sides of the flat plate in opposite directions, and one of the bent portions is formed with a bolt hole through which a bolt is inserted, and the other bent portion is used upward. And

  The mounting jig of the present invention is a wall material (lower wall) that is already attached to the trunk edge by tightening the bolt in a state in which the hanging metal fitting and one bent portion (downward bent portion) of the plate-like member are in contact with each other. When the other wall member (upper wall member) above the lower wall member is attached, the lower end of the upper wall member is supported by a plate-like member. That is, a receiving surface for receiving the lower end of the upper wall material is formed between the hanging metal fitting and the other bent portion (upward bent portion) of the plate-like member, and the lower end of the upper wall material is in contact with the receiving surface. Thus, the upper wall material can be supported from below. Moreover, since the receiving surface is formed between the hanging metal fitting and the upward bent portion, the upper wall material is difficult to drop off.

  Therefore, when attaching the upper wall material to the body edge, for example, a state in which a plurality of mounting jigs are hung on the upper end of the lower wall material and the lower end side of the upper wall material is placed on these mounting jigs After attaching the upper end side to the trunk edge, remove the mounting jig from the lower wall material, and then attach the lower end side of the upper wall material to the trunk edge. If it does in this way, since it only has to attach the upper end side and lower end side of an upper wall material in order, it becomes possible to work with few manpower, and the danger from a fallen object can be avoided. Further, since the mounting jig is suspended from the upper end of the lower wall material extending horizontally, the upper wall material supported by the mounting jig is horizontally disposed. For this reason, if the mounting jig is used, the horizontal adjustment of the upper wall material can be easily performed with high accuracy. Here, when removing the mounting jig from the lower wall material, loosen the nut, create a gap between the hanging bracket and the downward bent part of the plate-like member, and the lower end of the upper wall material is located in the gap It can be easily removed by lifting it up.

  Specifically, the wall material construction method using the mounting jig of the present invention includes a step of suspending the mounting jig on the upper end of the wall material attached to the body edge of the building, and other different from the wall material. Attaching the upper end side of the other wall material to the trunk edge in a state where the lower end of the wall material is placed on the plate-like member of the mounting jig suspended from the wall material, and a bolt of the mounting jig The step of removing the mounting jig from the wall material by loosening and forming a gap between the hanging bracket and the plate-like member and lifting the mounting jig so that the lower end of the other wall material is located in this gap And a step of attaching the lower end side of the other wall material to the trunk edge.

  By the way, in recent years, lifting devices that mechanically raise and lower work scaffolds have become widespread, and if such lifting devices are introduced into the work of attaching wall materials, there is no need to provide temporary scaffolds and the construction period can be shortened. And cost reductions can be expected. However, since this type of lifting device usually has a structure that raises and lowers a one-stage scaffold, it is necessary to raise and lower at least two-stage scaffolds having different heights in order to be used for wall mounting work. In that case, in order to clear the limit on the loading weight of the lifting device, the horizontal length of the scaffolding at each stage must be shortened to reduce the weight, resulting in a narrow working range and reduced working efficiency. Will be invited.

  On the other hand, when the mounting jig of the present invention is used, the wall material can be mounted using a known lifting device that lifts and lowers the one-step scaffold. For this reason, in the construction of the wall material using the mounting jig, if the wall material attached to the trunk edge is transported by the lifting device, in addition to reducing the construction cost of providing a temporary scaffold, Since it is not necessary to suspend the wall material with a rope from the top of the roof or to suspend the wall material with a crane, the safety and work efficiency of the wall material mounting work can be improved.

  Hereinafter, an embodiment of a mounting method and a wall material construction method using the mounting jig of the present invention will be specifically described with reference to the drawings.

  As shown in FIG. 4, a siding 1 is used in a factory, a warehouse, or the like as a wall material that closes a framework of a steel frame from the outside. As the siding 1, a metal plate material processed into a corrugated shape is used as a general-purpose material excellent in terms of light weight, aesthetics, durability, and cost.

  The framework of a steel building is composed of, for example, main pillars (not shown) made of, for example, H-shaped steel, which are set up on a concrete foundation at a predetermined interval. The trunk edge 3 is attached and configured. A siding 1 is longitudinally and laterally attached to the frame of such a steel building from the outside one by one.

  The siding 1 positioned at a predetermined position of the trunk edge 3 is fixed to the trunk edge 3 by drilling a pilot hole with a drill while being pressed against the trunk edge 3 and tightening a drill screw, for example. The size of the siding 1 is adjusted to an appropriate size according to the shape and size of the building. Here, the vertical length is, for example, 6 to 8 m. Shall be used.

  Next, the configuration of the mounting jig that is a feature of the present invention will be described with reference to FIG. The attachment jig 5 is used when attaching the siding 1 to the trunk edge 3 and is a suitable tool for longitudinally connecting the siding 1.

  The mounting jig 5 according to the present embodiment is configured to include a suspension fitting 7 and a plate-like member 9, and is used in a state where the suspension fitting 7 and the plate-like member 9 are fixed to each other by a bolt 11 and a nut 13. . The hanging metal fitting 7 is composed of two long plate members 15, and each plate member 15 is provided with a folded portion 17 that is folded at one end side to the other end side, and in the direction orthogonal to the plate member 15 at the other end side. A bolt hole (not shown) that penetrates is formed. The hanging metal fitting 7 is not limited to a plate material but may be a bar material.

  The plate-like member 9 is formed by bending a substantially rectangular flat plate along two fold lines 19 and 21 parallel to each other in the opposite direction at a substantially right angle. That is, the plate-like member 9 includes a receiving surface 23 sandwiched between the folding lines 19, 21, a bending surface 25 formed by bending the receiving surface 23 along the folding line 19, and the receiving surface 23 as a folding line. And a bent surface 27 formed by being bent along the line 21. Bolt holes (not shown) penetrating in a direction orthogonal to the bending surface 25 are formed at two places on the bending surface 25.

  As shown in FIG. 1, the suspension fitting 7 and the plate-like member 9 are configured such that the bolt 11 is inserted into the bolt hole from the suspension fitting 7 side, and the nut 11 is attached to the bolt 11 protruding from the bolt hole of the plate-like member 9 (bending surface 25). 13 are fastened to each other by being tightened. When the bolt 11 and the nut 13 are completely tightened, the plate-like member 9 is fixed in a state where the bent surface 25 is in contact with the suspension fitting 7. At this time, the suspension fitting 7 is arranged with the folded portion 17 folded back in the direction opposite to the plate-like member 9, and the plate-like member 9 has the bent surface 27 substantially parallel to the longitudinal direction of the suspension fitting 7 and the suspension fitting 7. Are arranged in a state of being bent from the receiving surface 23 in a direction (upward in FIG. 1) in which the folded portion 17 is located.

  As described above, the mounting jig 5 is a single component in a state in which the suspension fitting 7 and the plate-like member 9 are fastened to each other by the bolt 11 and the nut 13. The bolts 11 and the nuts 13 are removed, and are transported to a siding installation site (scaffold) in a separated state, and assembled and used as necessary.

  Next, the procedure for attaching the siding to the trunk edge 3 using the attachment jig 5 configured as described above will be described with reference to FIGS.

  First, as shown in FIG. 2A, the hanging bracket 7 of the mounting jig 5 is attached to the upper end of the siding 1. Here, the suspension fitting 7 is suspended from the upper end of the siding 1 by hooking the folded portion 17 on the upper end of the siding 1. The suspension fittings 7 are attached to a plurality of locations (two locations in FIG. 2) at the upper end of the siding 1 with a predetermined interval. Bolts 11 are inserted into the bolt holes of the respective hanging brackets 7 with the siding 1 as the back, and the bolts 11 protrude in the front side, that is, in a direction opposite to the folding direction of the folded portion 17 of the hanging bracket 7. .

  Next, as shown in FIG. 2B, the plate-like member 9 is fixed to the two suspension fittings 7 via the bolts 11 and the nuts 13 so that the bent surface 27 faces upward. The bolt 11 and the nut 13 are tightened until the hanger 7 and the bent surface 25 abut.

  Next, as shown in FIG. 2 (c), the lower end of another siding 31 to be mounted on the siding 1 is temporarily placed on the receiving surface 23 of the mounting jig 5, and the other siding 31 is supported from below. In this state, the upper end side of the other siding 31 is fixed to the trunk edge. Here, the siding 31 may move in a direction in which the lower end moves away from the hanging bracket 7 for some reason. However, since the siding 31 is formed with the bent surface 27 rising in the moving direction of the siding 31, the siding 31 is attached. It is possible to prevent the tool 5 from falling off.

  Subsequently, the mounting jig 5 is removed from the upper end of the siding 1 in order to fix the lower end side of the other siding 31 to the trunk edge. Here, the procedure for removing the mounting jig 5 from the siding 1 will be described with reference to the cross-sectional view of FIG.

  As shown in FIG. 3A, the lower end of another siding 31 is in contact with the receiving surface 23 of the mounting jig 5 suspended from the siding 1.

  In this state, as shown in FIG. 3 (b), the nut 13 is loosened to create a gap 33 between the suspension fitting 7 and the bent surface 25 of the plate-like member 9, and the lower end of the other siding 31 is formed in the gap 33. The mounting jig 5 is lifted so that the part is positioned. At this time, since the upper end side of the other siding 31 is fixed to the trunk edge, even if the lower end is located in the gap 33 and is not supported from the receiving surface 23, it does not fall. If the lower end of the other siding 31 is positioned in the gap 33 in this way, the mounting jig 5 can be easily lifted. When the mounting jig 5 is lifted, the folded portion 17 of the hanging bracket 7 is detached from the upper end of the siding 1, so that the mounting jig 5 is separated from the siding 1.

  Next, as shown in FIG. 3C, the mounting jig 5 in which the folded portion 17 of the hanging bracket 7 is detached from the upper end of the siding 1 is passed through the hanging bracket 7 between the siding 1 and the other siding 31. Pull it down.

  Then, as shown in FIG. 3D, after the mounting jig 5 is extracted, the lower ends of the other sidings 31 are fixed to the trunk edge so as to overlap the upper ends of the sidings 1.

  The mounting jig 5 can be removed from the siding 1 in this manner when the mounting jig 5 is lifted with the lower end of the other siding 31 positioned in the gap 33 of the mounting jig 5. This is because the folded portion 17 of the hanging bracket 7 is detached from the upper end of the siding 1 before the lower end of the other siding 31 comes into contact with the bolt 11. That is, as shown in FIG. 1, the mounting jig 5 is set such that the distance A from the folding line 19 of the folding surface 25 to the edge of the bolt hole is longer than the folding length B on the inner peripheral side of the folding portion 17. Has been.

  Next, with reference to FIG. 4, the siding attachment work using the attachment jig 5 will be described more specifically.

  A lifting device (not shown) that mechanically lifts and lowers the working scaffold is arranged outside the torso edge, and the height of the scaffold can be freely adjusted by the operator's operation or remote operation from the ground. Yes. The lifting device is provided with a single-stage scaffold 35, and using this scaffold 35, the mounting jig 5 and the mounting siding are conveyed upward. It is assumed that a conventional temporary scaffold is not provided.

  First, as shown in FIG. 4A, the attachment jig 5 is suspended from the upper end of the siding 1 already attached to the trunk edge 3. The attachment method of the attachment jig 5 is as described in FIG. In FIG. 4A, the worker is omitted.

  Next, as shown in FIG. 4 (b), the height position of the scaffold 35 is moved upward, and two workers hold the upper end side of the newly installed siding 31, and the lower end of the siding 31 is attached. Temporarily placed on the jig 5.

  Then, as shown in FIG. 4 (c), two workers hold the upper end side of the siding 31, and after positioning the siding 31 with respect to the trunk edge 3, The left and right sides are fixed to the trunk edge 3.

  Subsequently, as shown in FIG. 4 (d), the height position of the scaffold 35 is moved downward, the attachment jig 5 is removed, and then the left and right sides of the lower end side of the siding 31 are fixed to the trunk edge 3. .

  In this manner, the mounting jig 5 is suspended from the upper end of the horizontally installed siding 1, so that the siding 31 supported by the mounting jig 5 is disposed horizontally. For this reason, if the mounting jig 5 is used, the horizontal adjustment of the siding 31 can be easily performed with high accuracy. Further, if the mounting jig 5 is used, the upper end side and the lower end side of the siding 31 can be attached to the trunk edge 3 in order, so that all the operations for attaching the siding 31 to the trunk edge 3 can be performed by, for example, two people. It can be performed by a worker with only one stage of scaffolding. Therefore, the number of workers can be reduced to, for example, half, and the danger of falling objects from the upper side can be avoided, so that the safety of work can be improved.

  In addition, when the mounting jig 5 is used, a known lifting device that lifts and lowers the one-stage scaffold can be introduced into the siding mounting work. As a result, it is not necessary to provide a temporary scaffold as in the prior art, and construction costs can be reduced. Also, if the siding is transported with a lifting device, it is not necessary to hang the siding temporarily placed on the roof or a dedicated rack with a rope or work with a crane, as in the past, Work safety and efficiency can be increased.

  As mentioned above, although embodiment of this invention has been explained in full detail with drawing, the said embodiment is only an illustration of this invention and this invention is not limited only to the structure of the said embodiment. Needless to say, even if there is a design change within a range not departing from the gist of the present invention, it is included in the present invention.

  For example, in the mounting jig 5, the example in which the plate member 9 is fastened with the bolt 11 and the nut 13 in the state where the hanging bracket 7 is suspended from the upper end of the siding has been described. The siding member 9 may be suspended from the upper end of the siding while being fixed by the bolt 11 and the nut 13.

  Further, although the example in which the mounting jig 5 is formed by bending the bending surface 27 at a substantially right angle with respect to the receiving surface 23 has been described, the angular range is such that the siding that contacts the receiving surface 23 does not fall off the receiving surface 23. If it is, it is not limited to this angle.

  Moreover, although the example which uses the raising / lowering apparatus which raises / lowers one step | paragraph scaffold was demonstrated as a method of ensuring a worker's scaffold, in addition to this function, for example, a raising / lowering apparatus is built along the rail formed on the ground. The elevating device can also have a function of moving freely in the width direction. According to this, the merit that it is not necessary to provide a temporary scaffold can be maximized, and a wide range of work areas can be safely constructed in a shorter time.

  Further, in the present embodiment, the siding attachment work formed in a metal corrugation has been described as an example. However, the present invention is not limited to this. For example, the siding formed of a synthetic resin such as FRP or polycarbonate is not limited thereto. Alternatively, a siding formed other than a corrugated shape can achieve the same effect by using a mounting jig having the technical idea of the present invention.
