Jitsukaihei 6-4253 Gazette

The scaffolding 101 is used as a passage for a worker at a construction site to perform rebar assembly work, formwork construction work, outer wall and roof installation work, and the like. Further, in order to improve the work efficiency, the scaffold 101 is usually assembled higher than the building, so that it is difficult to support the upper end side thereof, and the scaffold 101 has a structure that is easily shaken by strong wind or vibration due to the movement of the worker. Therefore, in order to prevent the scaffolding 101 from collapsing or the like, a support structure for the scaffolding 101 that supports and stabilizes the upper end side of the scaffolding 101 is required. At present, the upper end side of the scaffold 101 is forcibly connected to the roof of a building or the like, but there is a problem that reliable support cannot be obtained and the roof is damaged.

As described above, in the support device 100, the support member 102 is fixed to the upper surface of the folded plate roof 105. Then, the upper end side of the scaffold 101 is fixed to the connecting member 103 arranged on the support member 102 via the single pipe 106. With this structure, the upper end side of the scaffold 101 is fixed to the folded plate roof 105, and the stability of the scaffold 101 is greatly improved.

However, the support member 102 of the support device 100 is not a frame shape but a long single shape, and is arranged substantially in parallel with the scaffold 101. Then, in conjunction with the shaking of the scaffold 101, an external force pulled or pushed through the single pipe 106 is repeatedly applied to the support member 102. At this time, the support member 102 and the folded plate roof 105 have a structure of being fixed by the bolt 107 and the nut 108, and stress concentration is likely to occur in the fixed portion, the folded plate roof 105 of the fixed portion is damaged, and the folded plate roof 105 is damaged. , There is a problem that the bolt 107 is easily damaged due to metal fatigue.

Further, since the folded plate roof 105 is usually arranged so as to be inclined toward the scaffolding 101 side (eaves side), the support member 102 is easily twisted by an external force when the support member 102 has a long single plate shape. It is difficult to obtain a reaction force that opposes the external force that is pulled, and there is a risk that the scaffolding 101 will collapse if the support device 100 comes off the folded plate roof 105.

Further, in a state where the connecting member 103 is fixed in the vertical direction with respect to the upper surface of the supporting member 102, one universal clamp 109 is used when the other end side of the single pipe 106 is fixed to the connecting member 103. There is a problem that it is difficult to firmly fix the single pipe 106 to the connecting member 103. As a result, when the single pipe pipe 106 is strongly pulled in conjunction with the movement of the scaffolding 101 to greatly shake due to a strong wind or the like, the single pipe pipe 106 comes out of the universal clamp 109, and the scaffolding 101 collapses. There is also a risk that it will end up. Furthermore, since the single pipe 106 and the connecting member 103 are not connected in a linear positional relationship, the reaction force is not firmly transmitted to the external force from the scaffolding 101, and it is difficult to stably support the scaffolding 101. There's a problem.

Further, the scaffold 101 is usually arranged along the building over a wide area around it. A plurality of support devices 100 are installed on the upper surface of the folded plate roof 105 to evenly support the plurality of scaffolds 101, thereby improving the stability of the scaffold 101. Therefore, a plurality of support devices 100 will be used at one construction site. However, in the structure in which the connecting member 103 is fixed in the vertical direction with respect to the upper surface of the support member 102, it is difficult to stack and store the support devices 100, and there is a problem that the storability and portability are poor.

In addition, at the construction site, building materials such as scaffolding materials are lifted together on the upper surface of the folded plate roof 105 by a crane car or the like, and the work is carried out while temporarily placing the building materials on the upper surface of the folded plate roof 105. In some cases, efficiency may be improved. At this time, there is a problem that the folded plate roof 105 may be damaged by placing the building material directly on the upper surface of the folded plate roof 105. Furthermore, a rope for loading and unloading is used during the crane work, but the rope for loading and unloading is sandwiched between the building material and the folded plate roof 105, and the rope for loading and unloading is difficult to pull out, resulting in poor workability. There's a problem. On the other hand, when the crane work is forcibly pulled out, there is a problem that the building material may collapse, the roof may be damaged, and the collapsed building material may fall. Similarly, when a worker walks directly on the upper surface of the folded plate roof 105, there is a problem that the roof is damaged and it is difficult to secure the safety of the worker.

In addition, in a business store, a signboard is installed at the upper end of the roof in order to appeal the store name to customers, but a support structure for safely installing the signboard is required. In the conventional support structure, in order to secure the desired support force, a hole is once made in the folded plate roof 105 to pass the support pipe, and the support pipe is welded and fixed to the beam of the business store, and then the folded plate roof 105 is formed. It was blocking the above hole. Therefore, there is a problem that the folded plate roof 105 is damaged and the location of the hole is likely to cause rain leakage.

With this structure, the connecting rod portion 15B can be connected to the connecting member 31 so as to be linear along the longitudinal direction of the connecting member 31. Then, the scaffolding 41 sways in the front-rear direction due to a strong wind or the like, and the scaffolding 41 inclines in a direction away from the building, so that an external force pulled by the connecting member 31 is applied to the connecting rod portion 15B. When the external force to be pulled is applied, the connecting rod portion 15B and the connecting member 31 are in a linear positional relationship, so that the connecting member 31 is moved to the goby type folded plate roof 11 side with the largest possible reaction force. Can be pulled back.

That is, since the connecting rod portion 15B can rotate within the range of about 90 degrees even in the state of being connected to the connecting member 31, the connecting member 31 and the goby type folded plate roof 11 due to the shaking of the scaffold 41. Even if the angle formed by the above changes, the connecting rod portion 15B can also rotate in conjunction with the connection rod portion 15B. Then, by bringing the connecting rod portion 15B and the connecting member 31 closer to the linear positional relationship, the upper end side of the scaffold 41 can be supported by the largest possible reaction force.

Even when the scaffolding 41 is tilted toward the building and an external force is generated to push the connecting rod portion 15B toward the goby-type folded plate roof 11 side via the connecting member 31, the connecting rod portion 15B and the connecting member 31 By maintaining the linear positional relationship or the positional relationship close to the linear relationship, the connecting member 31 can be pushed back toward the scaffold 41 with the largest possible reaction force. Then, the scaffolding 41 can be prevented from falling toward the building side.

It is arranged on the upper end side of the rod portion 15B.

With this structure, the connecting rod portion 15B and the connecting member 31 can be firmly connected by the two universal clamps 32 and 33. In particular, when an external force that pulls the connecting rod portion 15B via the connecting member 31 is generated and the connecting member 31 is about to be pulled out from the connecting rod portion 15B, first, the universal clamp 33 is attached to the stopper portion 15C. By being caught, the connecting member 31 is prevented from being pulled out from the connecting rod portion 15B.

As described above, the frame body portion 13 is fixed to the goby portion 12 via the fixing portion 16 at least on the lower surfaces of the first frame 13A and the second frame 13B. With this structure, the support device 10 counters the external force to be pulled and the external force to push in, not as a line by the conventional support member 102 shown in FIG. 11, but as a surface as a frame body portion 13. It becomes difficult to come off from the goby portion 12, and the scaffold 41 (see FIG. 3) can be supported more firmly. Further, since the external force applied to the individual fixed portions 16 can be dispersed, the load on the individual fixed portions 16 and the load on the goby-type folded plate roof 11 including the goby portion 12 are alleviated, and the fixed portions 16 are damaged. And damage to the goby portion 12 can be prevented.

As shown in FIG. 3, the scaffolding 41 is used as a passage for a worker at a construction site to perform rebar assembly work, formwork construction work, outer wall and roof installation work, and the like. The scaffolding 41 is usually assembled higher than the building in order to improve the work efficiency and avoid the edge structure of the roof. The scaffolding 41 has a structure that is easily shaken by strong winds, vibrations caused by the movement of workers, and the like. By fixing the upper end side of the scaffold 41 to the goby type folded plate roof 11 at the location, the stability of the scaffold 41 can be significantly improved. In FIG. 3, for convenience of explanation, the goby portion 12 is omitted.

As described above, the goby portion 12 (see FIG. 2) is continuously formed from the upstream end (top of the roof) to the downstream end (roof eaves) according to the slope of the goby type folded plate roof 11. The support device 10 can be installed at any position on the goby-type folded plate roof 11 according to the length and angle of the connecting member 31. Then, by making the span between the first frame 13A (see FIG. 1 (B)) and the second frame 13B (see FIG. 1 (B)) correspond to the span between the goby portions 12, the goby type folded plate roof 11 The scaffold 41 can be supported not only on the scaffold 41 on the eaves side but also on the scaffold 41 on the side of the goby type folded plate roof 11 via the support device 10 and the connecting member 31.

With this structure, the support device 10 can also support the scaffolding 41 at any position around the building within the range where the connecting member 31 reaches the goby portion 12 of the goby type folded plate roof 11. Then, in the support device 10, the frame body portion 13 functions as a surface and can counter the external force of pulling and the external force of pushing due to the shaking of the scaffold 41, which can greatly improve the stability of the scaffold 41. can.

In the present embodiment, the case where the support device 10 is connected to the connecting member 31 to support the scaffold 41 has been described, but the present invention is not limited to this case. For example, the support device 10 is arranged along the end of the goby type folded plate roof 11 at regular intervals, and a single pipe of about 1 m is attached to the tip side of the connecting rod portion 15B to attach the master rope.

Then, the insertion receiving portions 66 of the pair of support devices 60 are bridged by the wedge type pipes 81 and 82, and the hooks on both ends of the scaffolding plate 84 are hooked on the wedge type pipes 81 and 82, whereby the scaffolding plate 84 A passage is formed on the wedge-shaped folded plate roof 11. With this structure, it is greatly reduced that the worker directly walks on the upper surface of the goby type folded plate roof 11, the goby type folded plate roof 11 is less likely to be damaged, and the worker can work safely. Can be done.

Next, as shown in FIG. 10, the support device 60 can support the store signboard 91 installed at the upper end of the store provided with the goby-type folded plate roof 11. The store signboard 91 is installed at the end on the entrance side of the store or at the end along the main road, and has a large area and a large mass. Therefore, a support structure for safely supporting the store signboard 91 is required on the side of the goby-type folded plate roof 11, and conventionally, a hole is made in the goby-type folded plate roof 11 and a support member such as an L-shaped angle is provided in the store. It was welded and fixed to the beam.

A plurality of support devices 60 are installed on the goby-type folded plate roof 11 around the installation location of the store signboard 91. Then, as described above with reference to FIG. 2, a connecting member 31 that connects the store signboard 91 and the support device 60, for example, one end side of a single pipe, is connected via the universal clamps 32 and 33. With this structure, the store signboard 91 can be safely supported without making a hole in the goby-type folded plate roof 11.

Further, as shown in the figure, the connecting mechanism 63 of the support device 60 may be formed only from the support portion 15A. In this case, for example, an L-shaped angle is used as the connecting member 31 for connecting the store signboard 91 and the support device 60, and one end side of the L-shaped angle is welded and fixed to the frame of the store signboard 91, and the L-shaped angle is formed. The other end side of the above is welded and fixed to the support portion 15A. Alternatively, the other end of the L-shaped angle is bolted using a pair of holes 15E (see FIG. 1A) of the support portion 15A. With this structure, the store signboard 91 can be safely supported without making a hole in the goby-type folded plate roof 11.
