Description

The present invention relates to a load-receiving stage and its mounting method, and more particularly to a load-receiving stage that protrudes from the flat side (front side) of a frame scaffold or a single-tube scaffold and a mounting method for mounting this load-receiving stage to the scaffold.

In general, when constructing, dismantling, or repairing structures such as buildings, or constructing, dismantling, or repairing structures such as bridges, frame scaffolding or single-pipe scaffolding is installed at the construction site of the building or structure, and these scaffoldings are used. Workers are doing various works.

When performing this work, especially when working in high places, it is difficult to transport building materials, construction materials, etc. to a frame scaffold or a single pipe scaffold each time, and it takes time to transport. A load-receiving stage is provided on the flat side of the single-pipe scaffold, materials, tools, etc. It is normal to do

In this case, in order to install the load-receiving stage on the frame scaffolding or the single-tube scaffolding, the load-receiving stage is assembled on the ground in advance, as shown in Patent Document 1, for example, and then the load-receiving stage is lifted by a crane to flatten the frame scaffolding. In addition, with this load receiving stage suspended, the mounting bracket provided on this load receiving stage is attached to the frame of the frame scaffolding, and the diagonal material provided at the bottom of the load receiving stage is connected to the building material of the building frame. do.

JP-A-11-148225

However, although there is no functional defect in the load-receiving stage and its mounting method disclosed in Patent Document 1, it is desired to improve the following problems.

In other words, when the load receiving stage is transported to the flat side of the framework scaffold, it is suspended by a crane, so it is necessary to install a crane at the construction site, so the equipment cost is high, and the transportation and installation work of the crane is high. is also difficult.

Furthermore, since the operator must attach the fittings and the diagonal members from the framework scaffold side while the load receiving stage is suspended, the work is difficult and requires skill.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a load-receiving stage that can be assembled on a framework scaffold or a single-tube scaffold without using a crane, and a method of mounting the same.

In order to achieve the above object, the load receiving stage means of the present invention is a load receiving stage provided overhanging on the flat side of a frame scaffold or a single-tube scaffold. A frame mounting member rotatably provided at one end, a pair of upper and lower handrail mounting members provided at the other end of each gable side frame, a pair of handrail supports attached to each of the handrail mounting members, and each gable side. A scaffolding board bridged between frames, and a gable side disposed above each gable side frame and detachably installed between the building material of the framework scaffolding or the column of the single pipe scaffolding and the handrail column. A handrail, a flat side handrail installed between the handrail supports, and one end connected to the lower part of each gable frame and the other end detachably attached to the building material or the support via a diagonal member. one end of each of the gable-side frames is rotatably attached in the circumferential direction to the building material or the support of the single-tube scaffolding via the frame attachment members. is.

Similarly, the method of mounting the load-receiving stage is such that the load-receiving stage comprises a pair of gable-side frames opposed to each other, a frame mounting member rotatably provided at one end of each gable-side frame, and the other end of each gable-side frame. a pair of upper and lower handrail mounting members provided on the upper and lower sides, a pair of handrail support columns attached to each of the handrail mounting members, a scaffolding board bridged between the gable side frames, and arranged above the gable side frames. A gable side handrail detachably installed between the building material of the framework scaffolding or the single pipe scaffolding support and the handrail supports, a flat side handrail provided between the handrail supports, and the gable side frame. and a diagonal material having one end connected to the lower part and having the other end detachably attached to the building material or the pillar via a diagonal material attachment member, and is used for the frame scaffolding or the single-tube scaffolding flat. a step of arranging the gable-side frames on the side, then rotatably attaching one end of each gable-side frame to the building material of the framework scaffolding or the strut of the single-tube scaffolding via the frame attachment members; a step of attaching the handrail post to the building material or the post via the diagonal member mounting members, and attaching the handrail post to the gable frame via the handrail mounting member, and attaching both ends of the gable handrail to the building material or the post, respectively. a step of attaching the post and the handrail post; a step of rotating each of the gable-side frames about the building material or the post by 90 degrees from the flat side to the gable side; The method comprises a step of erecting the scaffolding board between the pair of gable -side frames, and a step of erecting both sides of the flat-side handrail on the scaffolding board between the pair of the opposing handrail supports. It is something to do.

According to the invention of each claim, a pair of gable-side frames are rotatably attached in advance to the building material of the frame scaffolding or the support of the single-tube scaffolding and arranged on the flat side, and then the gable-side handrails are attached to the gable-side frames. Since the scaffolding board and the flat side handrail can be sequentially assembled by using the gable side frame from this state, the frame scaffolding side or the single pipe scaffolding can be assembled without using a crane or the like. You can set up a receiving stage on the side.

Therefore, there is no need to prepare a crane or the like each time, and workability and economic efficiency can be improved.

As shown in FIGS. 16, 18 and 22, the lower diagonal member 11A is a vertically elongated body plate portion rotatably supported by the other end of the diagonal member 10 via a bracket C. 46, a known clamp 47 attached to the upper end of the main body plate portion 46 in the drawing, and a backing plate 48 having an arcuate cross section provided to the lower end of the main body plate portion 46 in the drawing.

Thus, in this example, the building material U is held by the clamps 47 and the backing plate 48 is brought into contact with the outer periphery of the building material U at the same time. It can be distributed in two places.

In particular, in this example, as shown in FIGS. Not only the building material U but also the horizontal member Y can receive the force acting from the load receiving stage SA via the diagonal member 10 .
