Description of the Related Art In the construction work of various plants and factories, a scaffolding frame in which a number of pipes are connected by a joint is constructed, and a scaffolding plate is used to bridge a scaffolding plate. Temporary scaffolds, such as frame scaffolds, are often used. For example, for a pipe scaffold, a pipe frame composed of a combination of squares in which a number of pipes of a given length are connected via a cross, T-shaped or L-shaped joint is constructed along the building surface. Then, the scaffold plate is hooked over a pair of horizontally arranged pipes of the pipe frame which are arranged in parallel, and the scaffolding plate is continuously arranged to secure a scaffold passage which requires work.

れている。[0003] Conventionally, in assembling and repairing pipes and ducts, there are many moving operations that are performed while moving along the lines of pipes and ducts, rather than generally stopping at one place. For such an operation, a temporary scaffold having a structure in which one scaffold plate is suspended between upper end portions of a pair of stepladders is often used.

ほど大きくなるという欠点がある。However, in the case of a temporary scaffold having a structure of a pipe scaffold or a frame scaffold which has been frequently used, as in the former, as the construction progresses, the equipment piping may interfere with the scaffold material. Then, it is necessary to dismantle the temporary scaffold and reassemble to avoid interference. Therefore, there is a disadvantage that the time and labor waste required for the disassembly and assembly are so large that they cannot be ignored.

の無駄は、作業効率上無視できない。In the latter work using a temporary scaffold having a structure in which a scaffold plate is hung between a pair of stepladders, work at one place is generally completed in a short time, but the work is often changed frequently. . For this reason, although the work efficiency is better than the pipe scaffold or the frame scaffold, the waste of time, labor, and cost for temporarily dismantling the temporary scaffold and transporting it to the next work site cannot be ignored in terms of work efficiency.

る。Further, when moving a plurality of dismantled scaffold members from a work place to another work place together with the former and the temporary scaffolds, the scaffold members must be bundled and carried on a cart or the like each time. Therefore, there is a disadvantage that the bundled work requires wasted time and labor. In particular, when moving in a narrow place or a place with many bends, there is a problem that the dismantled scaffold members cannot be moved unless they are bundled compactly.

The present invention has been made in view of such circumstances, and it is an object of the present invention to provide an assembling type temporary scaffolding capable of compactly storing a pair of stepladders and a scaffold plate after disassembly and easily transporting the members.

One of the stepladders is a stepladder plate, a pair of lifting ladders supporting both ends of the stepladder plate via a rotating member, and both side edges of one of the pair of lifting ladders. A pair of handrail members attached to the base member, and the pair of lifting ladders are respectively turned toward the upper side of the stepladder scaffold with the pivoting member as a fulcrum. The ladder and the pair of handrail members form five surfaces of a rectangular parallelepiped, and the other one surface of the rectangular parallelepiped forms a storage opening, and the scaffold member and the other stepladder are formed in the storage body. Can be stored.

と干渉しないようにパイプ径が若干小さくなっている。A pair of main body handrails 20 are detachably provided on the longitudinal side edge of the scaffold plate main body 18. The main body handrails 20 are provided by inserting the support pipes 20A into cylindrical support members 29 provided at four corners of the upper surface of the scaffold plate main body 18, respectively, and stand up. The upper end portion and the intermediate portion of the pipe 20A are connected by a horizontal pipe 20B. On the other hand, the extended scaffold plate 22
Is provided with an extended handrail 24 which can be extended with respect to the main handrail 20 in a detachable manner. The extended handrail 24 is provided on a cylindrical support member 29 provided at both corners at one end of the extended scaffold plate 22, and column pipes 24 </ b> A erected respectively, and from the upper end and the intermediate portion to the side edge of the scaffold. The horizontal pipe 2 of the main handrail 20 is bent in the direction along
0B respectively. The horizontal pipe 24B of the extended handrail 24 is extended and contracted so that it can enter and exit the horizontal pipe 20B on the main body side. Thereby, the extension handrail 24 is also pulled out from the horizontal pipe 20B as the extension scaffold plate 22 is pulled out from the scaffold plate main body. When the extended scaffolding plate 22 is inserted into the cavity of the scaffolding plate main body 18, the horizontal pipe 24B of the main handrailing 20 is inserted into the horizontal pipe 24B of the main handrailing 20.
The pipe diameter is slightly smaller so as not to interfere with

By engaging with a stepladder having the height of the plate 12, the assembled temporary scaffold 10 is assembled. Further, columnar reinforcing legs 26 are provided at both ends of the open end on the lower surface of the scaffold plate body 18, respectively. By reinforcing the scaffold member 12 with the reinforcing legs 26,
Even when the extended scaffold plate 22 is pulled out to the longest, sufficient strength with respect to the weight can be maintained, the bending of the scaffold member 12 can be removed, and stability can be maintained. This reinforcing leg 26
It can be expanded and contracted, and can adjust to the floor of any shape by adjusting the amount of insertion into the upper half of the lower half. The variable leg length structure of the reinforcing leg 26 can be easily realized by using a screw structure. For example, an arbitrary structure such as a bayonet mechanism can be adopted. Also, the reinforcing legs 26
Can be folded to the lower surface of the side edge of the scaffold plate body 18 with a mounting portion 28 provided at the base of the reinforcing leg 26 as a fulcrum, and is stored on the lower surface of the scaffold plate body 18 when not in use.

After disassembly, one stepladder forms a storage body, and all the members can be compactly and integrally stored by storing the other stepladder and the scaffolding member in the storage body. The scaffolding can be greatly reduced as compared with the scaffolding, and transportation between the workplaces can be easily performed in a short time. Further, at this time, since the casters are attached to the bottom surface of the storage body, no special transport cart is required, and transport is further facilitated. As a result, waste of time, labor, and cost can be eliminated, and work efficiency can be improved.
