Description

TECHNICAL FIELD The present disclosure relates to a temporary scaffold constructed by scaffolding constituent members such as posts, cloth materials, and scaffolding boards, and connection members that connect the scaffolding constituent members to each other.

For example, at construction sites, repair work sites, civil engineering work sites, etc. of various buildings, temporary scaffolding is constructed according to the scale and structure of the building. A general temporary scaffolding is constructed by combining a plurality of posts, cloth materials that connect the posts together, scaffolding boards, braces, handrails, and the like.

Among temporary scaffolds, there is a temporary scaffold equipped with a so-called preceding handrail, which is configured so that a handrail can be attached from downstairs prior to the installation of scaffolding boards on the upper floor. Temporary scaffolding equipped with preceding handrails is generally called next-generation scaffolding, etc., and has been adopted at many sites because of its excellent safety and workability (see Patent Documents 1 to 4, for example). .

The posts of the temporary scaffolds of Patent Documents 1 and 2 are provided with a plurality of vertically spaced pockets for connecting by inserting wedges of cloth materials or the like. In Patent Document 1, four pockets are provided radially at the same height, while in Patent Document 2, two pockets project horizontally opposite each other, and immediately below the two pockets are another two pockets. It is provided so as to protrude in a direction different from that of the upper two pockets.

In addition, the post of the temporary scaffolding of Patent Documents 3 and 4 is provided with a flange, and four insertion holes for connecting by inserting the wedge are formed in the flange at intervals in the circumferential direction. .

In addition, Patent Document 5 discloses a scaffolding configured so that when a scaffolding using a single pipe as a support and a scaffolding for a building frame are constructed adjacent to each other, the heights of the floorboards of both can be aligned.

JP 2011-47119 A Japanese Patent Application Laid-Open No. 2021-50490 JP 2012-215033 A Utility Model Registration No. 3222737 JP 2017-14803 A

Next-generation scaffolds include those with pockets on the columns (Patent Documents 1 and 2) and those with flanges on the columns (Patent Documents 3 and 4). There is one provided with two pockets (Patent Document 1) and one provided with pockets of different heights (Patent Document 2). Also, there are a plurality of shapes of the insertion hole of the flange. In other words, many manufacturers develop and sell next-generation scaffolding based on their own standards, and there are more than a dozen different standards. One standard of scaffolding components will be used. This is because different standards cannot be combined.

However, in emergency situations such as disaster recovery, or in large-scale construction sites with short construction periods, scaffolding components owned by a company building temporary scaffolding (or scaffolding owned by a leasing company) The construction of the scaffolding may be delayed due to the lack of numbers of components).

Even if the number of scaffolding constituent members of one standard is not available, for example, by combining the scaffolding constituent members of Patent Document 1 and the scaffolding constituent members of Patent Document 3, it is possible to obtain the required number. .

However, if the standards of the scaffolding constituent members are different, the height and shape of the connecting portion of the wedge will be different, so it has been difficult to construct a scaffold by combining scaffolding constituent members of different standards. The technique disclosed in Patent Document 5 is known as a technique for aligning the heights of scaffolding boards, but in order to align the heights, a large number of pillars with lengths different from general lengths are required. Become. There was a problem that it was not efficient to prepare and hold a large number of posts with different lengths.

The present disclosure is made in view of this point, and its purpose is to enable construction of one temporary scaffolding by combining scaffolding constituent members of different standards.

In order to achieve the above object, in one aspect of the present disclosure, a first scaffolding component manufactured according to a first standard and a second scaffolding component manufactured according to a second standard different from the first standard are provided. and a second scaffolding component interposed between the first scaffolding component and the second scaffolding component to connect the first scaffolding component and the second scaffolding component A temporary scaffold with connecting members can be assumed. Moreover, a connection member can also be made into the object of invention.

The connecting member has a first connecting portion to which the connected portion of the first scaffolding component is connected, and a second connecting portion to which the connected portion of the second scaffolding component is connected. have. The shape of the first connecting portion is a shape corresponding to the shape of the connected portion of the first scaffolding component, and the shape of the second connecting portion is the same as the shape of the first connecting portion. are different and have a shape corresponding to the shape of the connected portion of the second scaffolding component.

That is, the first scaffolding component is a standard for connecting wedges with pockets as in Patent Documents 1 and 2, and the second scaffolding component is a flange as in Patent Documents 3 and 4. If it were a standard for connecting a wedge to an insertion hole, it would be difficult to construct one temporary scaffold by directly connecting the first scaffolding component and the second scaffolding component. According to this, since the connection member is interposed between the first scaffolding component and the second scaffolding component, the first scaffolding component and the second scaffolding component are connected via the connection member. It becomes possible to construct one temporary scaffolding.

In another aspect of the present disclosure, although not particularly limited, the first connecting portion may be a pocket into which a wedge constituting the connected portion of the first scaffolding component is inserted, Further, the second connecting portion may be an insertion hole into which a wedge constituting the connected portion of the second scaffolding component is inserted. Thereby, the first scaffolding component having a wedge and the second scaffolding component having a wedge having a shape different from that of the first scaffolding component can be connected via the connecting member.

In another aspect of the present disclosure, the first connecting portion may be tubular into which a connected pipe portion constituting a connected portion of the first scaffolding component is inserted, and the second connecting portion The connecting portion may be cylindrical to be inserted into the connected pipe portion constituting the connected portion of the second scaffolding component. For example, if the first scaffolding component and the second scaffolding component are struts manufactured according to different standards, the connected pipe portion of the first scaffolding component is inserted into the first connecting portion. Also, by inserting the second connecting portion into the connected pipe portion of the second scaffolding component, it is possible to connect columns with different standards.

A connection member according to another aspect of the present disclosure may have a post and a clamp attached to the post. In this case, the clamp can be provided with the first connection portion and the second connection portion. Since the clamp can be fixed at any position in the height direction of the column, the degree of freedom in constructing the temporary scaffolding is improved.

A connection member according to another aspect of the present disclosure may have a support, and the support may be provided with the first connection portion and the second connection portion. For example, the strut can be provided with a pocket as a first connection and an insertion hole formed in the flange as a second connection.

A connection member according to another aspect of the present disclosure includes a cloth material, a wedge that constitutes the first connection part is provided at one end of the cloth material, and a wedge that constitutes the first connection part is provided at the other end of the cloth material. , a wedge forming the second connecting portion may be provided. In this case, when the first scaffolding constituent member and the second scaffolding constituent member are installed separately from each other in the horizontal direction, they can be connected by the connection member to construct one temporary scaffolding.

As described above, the first scaffolding component manufactured according to the first standard and the second scaffolding component manufactured according to the second standard can be connected via the connecting member. A single temporary scaffolding can be constructed by combining scaffolding constituent members of different standards while maintaining good workability and high safety without the need to supplement a portion where the number of materials is insufficient, for example, with a single pipe.

It should be noted that the following description of preferred embodiments is essentially merely illustrative, and is not intended to limit the invention, its applications, or its uses.

(Embodiment 1)
FIG. 1 is a front view of a temporary scaffolding 1 according to Embodiment 1 of the present invention. The temporary scaffolding 1 is constructed according to the content of the work, the scale of the work, and the like at construction sites of various buildings and civil engineering work sites. Temporary scaffolding 1 is constructed not only for construction work but also for maintenance work, various works, and the like. FIG. 1 shows an example of a temporary scaffolding 1 viewed from the front, which is constructed to have various heights and shapes according to the scale and structure of a building. The illustrated temporary scaffolding 1 is a multi-layer type with two or more floors, but is not limited to a multi-layer type and may be a single-layer type. Although FIG. 1 shows a case where the temporary scaffolding 1 is on the fifth floor, the present invention can also be applied to the temporary scaffolding 1 having the fifth floor or more. 1 is defined as the width direction of the temporary scaffolding 1, this is only for convenience of explanation and does not limit the direction of the temporary scaffolding 1. As shown in FIG.

The temporary scaffolding 1 is a wedge binding type scaffold that connects scaffolding constituent members with wedges, and is constructed by combining scaffolding constituent members of different standards. Of the temporary scaffolding 1, the first to third floors are the first scaffolding A constructed with the first scaffolding constituent members manufactured based on the first standard, and the fourth and fifth floors are the first scaffolding A. is a second scaffold B constructed of second scaffold components manufactured to a second standard different from the first standard. The number of floors of each scaffolding A, B is not particularly limited, and may be any number of floors.

Standards for temporary scaffolding with preceding handrails are broadly divided into, for example, the standard for inserting the wedge into the pocket and the standard for inserting the wedge into the insertion hole of the flange. , pocket size, shape, position, etc. are divided into multiple standards. It is different from the standard of The standard may differ for each manufacturing company (manufacturer).

In the form shown in FIG. 1, both the first scaffolding A and the second scaffolding B are of the standard for connecting by inserting wedges into pockets. are different in structure and shape, the size and shape of the pockets are different.

A specific description will be given below. The first scaffolding A consists of a first post 10, a first scaffold plank 11, a first leading handrail 12, a first leading brace 13, a first cloth material (not shown), a wall tie (not shown) (not shown), stairs (not shown), baseboards (not shown), and the like. The first strut 10 is constructed of a steel pipe or the like having a circular cross section installed on the ground surface C. As shown in FIG. A plurality of first pillars 10 are provided at intervals in the width direction of the temporary scaffolding 1 and are also provided at intervals in the depth direction. The first pillars 10 spaced apart in the depth direction are connected to each other by a first cloth member (horizontal member) (not shown).

As shown in FIG. 2, the first post 10 is provided with a plurality of first pockets 10a. The first pocket 10a is made of, for example, a steel plate and fixed to the outer peripheral surface of the first support 10 by welding. According to the first standard, four first pockets 10a are arranged at the same height and at intervals of 90° in the circumferential direction of the first strut 10 . A plurality of sets of four first pockets 10a are provided at intervals in the vertical direction.

The first struts 10 are connected vertically as required. That is, as shown in FIG. 3, a connected pipe portion 10b constituting a connected portion is provided on the upper portion of the first column 10. As shown in FIG. The connected pipe portion 10b has a cylindrical shape with a smaller diameter than the portion of the first support 10 below the connected pipe portion 10b, and is formed to be insertable into the lower portion of another first support 10. It is Since the connected pipe portion 10b has a relatively small diameter, a stepped portion 10c is formed at a portion of the first strut 10 corresponding to the lower end portion of the connected pipe portion 10b.

When connecting the first struts 10 vertically, the connected pipe portion 10b of the first strut 10 located on the lower side is inserted into the first strut 10 located on the upper side from below. When connected, the lower end portion of the first support 10 located on the upper side comes into contact with the stepped portion 10c of the first support 10 located on the lower side, thereby positioning the first support 10 located on the upper side in the height direction. done. At this time, the connected pipe portion 10b of the first support 10 positioned on the lower side is fixed to the lower part of the support 10 positioned on the upper side by a locking mechanism (not shown) so as not to come off from the support 10 positioned on the upper side. ing. The lock mechanism is configured to be unlockable by an externally operable operation section (not shown). This locking mechanism and operation part are conventionally known.

The first scaffold board 11 is a member that constitutes the working floor of the worker, and is also called, for example, an anti. Both ends of the first scaffolding board 11 are provided with wedges 11a protruding downward. The first scaffold board 11 can be connected to the first support 10 by inserting the wedge 11a into the pocket 10a of the support 10 from above.

The first leading handrail 12 and the leading brace 13 shown in FIG. 1 are configured to be attachable from the downstairs prior to the installation of the first scaffolding board 11 upstairs. Since the procedure for attaching the first leading handrail 12 and the leading brace 13 is well known, detailed description thereof will be omitted. A wedge (not shown) having the same size and shape as the wedge 11 a of the first scaffolding board 11 is provided on the members constituting the first leading handrail 12 and the leading brace 13 . The first leading handrail 12 and the leading brace 13 can be connected to the first column 10 by inserting the wedges of the first leading handrail 12 and the leading brace 13 into the pocket 10a of the first column 10 from above. It's like The first post 10, the first scaffold board 11, the first leading handrail 12, the first leading brace 13 and the first cloth material, which constitute the first scaffolding A, are manufactured based on the first standard. and a first scaffolding component.

As with the first scaffolding A, the second scaffolding B also includes a second post 20, a second scaffolding plank 21, a second leading handrail 22, a second leading brace 23, and a second cloth material (Fig. (not shown), wall ties (not shown), stairs (not shown), baseboards (not shown), and the like. Normally, the second scaffolding B is installed on the ground surface C in the same way as the first scaffolding A, but in this embodiment, it is installed on the first scaffolding A and together with the first scaffolding A A temporary scaffolding 1 is constructed.

As shown in FIG. 2, the second strut 20 has four pockets 20a arranged at the same height as the first strut 10, except that the pockets 10a of the first scaffold A are shaped differently. and differ in size. The second strut 20 is also vertically connected as required in the same manner as the first strut 10 . In other words, the upper portion of the second column 20 is provided with a small-diameter portion (not shown) having a smaller diameter than the intermediate portion and the lower portion. The small-diameter portion is formed so as to be insertable into the lower portion of the second support 20 . When connecting the second struts 20 vertically, the small-diameter portion of the second strut 20 located on the lower side is inserted into the second strut 20 located on the upper side from below. In other words, a connected pipe portion 20b constituting a connected portion is provided at the lower portion of the second column 20. As shown in FIG.

A lock mechanism 20c is provided on the connected pipe portion 20b of the second strut 20 . The lock mechanism 20c prevents the small-diameter portion of the second support 20 located on the lower side from coming off the connected pipe section 20b of the support 20 located on the upper side. The lock mechanism 20c is configured to be unlockable by an externally operable operation section (not shown). The locking mechanism 20c and the operating portion are conventionally known, but differ from the locking mechanism and the operating portion of the first column 10 because of their different standards.

The end of the second leading handrail 22 is provided with a downwardly projecting wedge 22a, and the end of the second leading brace 23 is also provided with a downwardly projecting wedge 23a. The second leading handrail 22 and the leading brace 23 can be connected to the second strut 20 by inserting the wedges 22a and 23a into the pockets 20a of the second strut 20 from above. A similar wedge (not shown) is also provided on the second scaffolding board 21. By inserting the second scaffolding board 21 into the pocket 20a of the second support 20 from above, the second scaffolding board 21 can be attached to the second support 20. can be connected to The second post 20, the scaffolding board 21, the second leading handrail 22, the second leading brace 23, and the second stretch fabric material, which constitute the second scaffolding B, are manufactured according to the second standard. 2 scaffolding components.

As described above, since the standards of the first scaffolding A and the second scaffolding B are different, it is difficult to construct one temporary scaffolding 1 as they are. In this embodiment, by using the connection member 30 shown in FIGS. 3 and 4, it is possible to construct one temporary scaffolding 1 by combining the first scaffolding A and the second scaffolding B with different standards. .

That is, the connecting member 30 is interposed between the first scaffolding component (specifically, the support 10) and the second scaffolding component (specifically, the support 20), and the first scaffolding component 10 and the second scaffolding component 20. More specifically, as shown in FIG. 3, the connection member 30 has a cylindrical shape extending vertically as a whole and is made of a high-strength material such as steel. A lower portion of the connecting member 30 serves as a first connecting portion 31 to which the connected pipe portion 10b of the first support 10 is connected. The first connection portion 31 has a shape corresponding to the shape of the connected pipe portion 10b of the first support 10, that is, a cylindrical shape into which the connected pipe portion 10b of the first support 10 is inserted. . Therefore, the inner diameter of the first connection portion 31 is set slightly larger than the outer diameter of the connected pipe portion 10b of the first support 10, so that the connected pipe portion 10b can be easily inserted. It's becoming The outer diameter of the first connection portion 31 is set to be substantially the same as the outer diameter of the portion of the first support 10 other than the connected pipe portion 10b. The lower end portion of the first connecting portion 31 contacts the stepped portion 10c of the first post 10 while the connected pipe portion 10b is inserted.

The first connection portion 31 is provided with a lock mechanism 31c for locking the connected pipe portion 10b of the first post 10 so that it does not come out of the first connection portion 31 when it is inserted. This locking mechanism 31c is the same as the locking mechanism provided on the first column 10, and also has a similar operating portion 31d (shown in FIG. 4). Therefore, locking of the first strut 10 is possible.

On the other hand, the upper portion of the connecting member 30 is a second connecting portion 32 to which the connected pipe portion 20b of the second strut 20 is connected. The shape of the second connection portion 32 is different from the shape of the first connection portion 31, and has a shape corresponding to the shape of the connected pipe portion 20b of the second support 20, that is, the shape of the support of the second support 20. It has a cylindrical shape to be inserted into the connecting pipe portion 20b. Therefore, the outer diameter of the second connecting portion 32 is set slightly smaller than the inner diameter of the connected pipe portion 20b of the second support 20, so that the second connecting portion 32 can be easily connected to the connected pipe portion 20b. can be inserted into the

A lock hole 32c is formed in the second connection portion 32 . A lock hole similar to the lock hole 32c is also provided in the small diameter portion of the upper portion of the second support 20. As shown in FIG. A lock mechanism 20c (shown in FIG. 2) provided in the connected pipe portion 20b of the second post 20 is configured so that a lock pin or the like can be inserted into the lock hole 32c of the second connection portion 32. It is configured. Therefore, the lock mechanism 20c of the second support 20 can be used to prevent the second connecting portion 32 from coming off.

A portion of the connection member 30 between the first connection portion 31 and the second connection portion 32 is an intermediate portion 33 . The outer diameter of the intermediate portion 33 is the same as the outer diameter of the first connecting portion 31 and larger than that of the second connecting portion 32 . Therefore, a stepped portion 30 c is formed at the boundary portion between the second connecting portion 32 and the intermediate portion 33 in the connecting member 30 . With the second connection portion 32 inserted into the second connection portion 20b of the second support 20, the lower end of the second support 20 abuts on the stepped portion 30c of the connection member 30. .

A pocket 30 a is provided on the outer peripheral surface of the intermediate portion 33 . The pocket 30a has the same shape and size as the pocket 20a provided in the second strut 20. As shown in FIG. That is, the pocket 30a of the intermediate portion 33 is configured to meet the second standard. As shown in FIG. 4, the four pockets 30a are at the same height and arranged at 90° intervals in the circumferential direction of the intermediate portion 33. As shown in FIG.

Therefore, as shown in FIG. 2, the second leading handrail 22 can be connected to the connecting member 30 by inserting the wedge 23a of the second leading brace 23 into the pocket 30a of the connecting member 30 from above. Also, depending on the height at which the connecting member 30 is installed, the wedge of the second scaffolding board 21 or the wedge 22a of the second preceding handrail 22 can be inserted into the pocket 30a of the connecting member 30 and connected.

As shown in FIG. 2, the connection member 30 is arranged so that the uppermost scaffolding board 11 of the first scaffolding A, the wedge 23a of the preceding brace 23 of the second scaffolding B, and the pocket 30a have an appropriate height relationship. It also functions as a spacer to make The vertical distance between the pocket 30a of the connecting member 30 and the pocket 20a of the second support 20 is set to a predetermined size such as 450 mm according to the standard. The vertical dimension F of the intermediate portion 33 may be set so as to achieve this dimension.

Further, the height of the pocket 30a is set as low as possible within a range where the uppermost scaffolding board 11 of the first scaffolding A and the wedge 23a of the leading brace 23 of the second scaffolding B do not interfere with each other. Note that the vertical dimension E of the pocket 30a differs depending on the standard of the second scaffolding B. As shown in FIG.

(Action and effect of the embodiment)
As described above, according to the first embodiment, when constructing a temporary scaffolding 1 of a desired size, only the scaffolding constituent members 10 to 13 of the first scaffolding A manufactured according to the first standard are used. If materials are not enough, it is possible to construct a temporary scaffolding 1 of a desired scale by combining the scaffolding constituent members 20 to 23 of the second scaffolding B manufactured according to the second standard. .

At this time, the connection member 30 can be interposed between the first support 10 and the second support 20 to connect the first support 10 and the second support 20 via the connection member 30. , There is no need to compensate for the shortage of materials with, for example, a single pipe. Therefore, one temporary scaffolding 1 can be constructed by combining the scaffolding constituent members 10 to 13 and 20 to 23 of different standards while maintaining good workability and high safety.
