Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction work of a building, or an up-and-down operation by a worker at a building exterior construction site.
The present invention relates to a frame scaffold that can be walked, assembled and disassembled easily.

[0002]

2. Description of the Related Art As a frame scaffold of this type, for example, the one disclosed in Japanese Utility Model Publication No. 1-18753 has been developed.

This frame scaffolding comprises a pair of front and rear building sites and a horizontal building installed between the building sites, and a plurality of the building sites are arranged side by side as lower building frames in the lateral direction. At the same time, one or a plurality of upper building frames having the same structure are detachably coupled to the lower building frame above, and scaffolding plates are removably installed between the lateral lands of adjacent building frames via hooks.

An X-shaped brace at the bottom and a handrail frame at the top are erected between the premises of the front comrades and the premises of the rear comrades laterally adjacent to each other to reinforce each premises and on the scaffold plate. For the safety of workers.

[0005]

The conventional frame scaffold has a simple structure, is easy to assemble and disassemble, and is safe and strong in strength, but has the following disadvantages.

1) Since the scaffolding board is constructed by hooking hooks provided at the ends thereof on the horizontal ground, a gap corresponding to the length of the hook is formed between the horizontal ground and the side surface of the scaffolding board. There is a danger that small tools, stoppers, debris, etc. will fall from above through this gap, and there is also the risk of an operator tripping in this gap, which is unsafe.

2) A brace and a handrail frame are provided on both sides of the scaffolding plate for safety for workers.
After all, there are many gaps and there is a danger that small tools, stoppers, debris, etc. will fall as well as the above.

Therefore, it is conceivable to arrange skirting boards on both sides of the scaffolding plate so as to prevent these members from falling, but in this case, the handrail frame, the brace, and the skirting board are separately constructed. The number of parts is large, the workability of assembly and removal is poor, and the economy, mountability, and workability are poor.

Therefore, an object of the present invention is to provide a space between scaffolding boards,
Providing a frame scaffold that improves safety by preventing gaps on the front and rear sides of each scaffold plate, has a small number of parts, and facilitates assembly and disassembly to improve economy, installation, and workability. That is.

[0010]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the structure of the present invention is such that a building frame is composed of a pair of front and rear building sites and a horizontal land installed between each building site, and In a frame scaffolding in which a plurality of scaffold boards are detachably installed between the lateral lands of the building frame that are installed side by side in the horizontal direction and are in immediate contact with each other, at least two vertical columns and the upper and middle parts of each vertical column A frame body is made up of a plurality of handrail struts and a skirting board installed between the lower parts of the vertical struts, and the frame body can be freely attached and detached between the adjacent front premises and the rear premises. In addition, the lateral ground is composed of a frame having a T-shaped cross section, and an engaging piece is projectingly provided at an end of the scaffolding plate, and the engaging piece is detachably connected to the frame. It is what

[0011]

Similarly, it is preferable that a supporting plate extending along the longitudinal direction is provided so as to protrude from the lower part of the inner peripheral surface of the skirting board, and a large number of scaffolding plates are arranged side by side on the supporting plate so as to be detachably coupled.

Similarly, it is preferable to mount a mountain-shaped support between the vertical support and the horizontal handrail which form the frame.

[0014]

[Operation] Since the vertical pillar, the handrail pillar and the skirting board form a frame, the vertical pillar, the handrail pillar and the skirting board can be assembled or removed on both sides of the scaffolding board at a time, and the scaffolding board By arranging the above-mentioned frames on both sides, the safety of the operator can be achieved, and there is no gap due to the skirting board, and tools, stoppers, debris, etc. are prevented from falling.

Further, by forming the lateral ground into a T-shape, there is no downward gap between the connecting points of the adjacent scaffold boards, or by arranging the scaffold boards by abutting them on the skirting board support plate. There is no gap between the scaffold boards.

When the pillar 25 is pushed up while pushing in the claw 26, the pillar 25 comes out of the hole 23, and the scaffold plate 5 can be removed.

When the scaffolding plates 5 are continuously laid in the lateral direction as described above, a gap L may be formed between the scaffolding plates 5 and 5 adjacent to each other as shown in FIG.

However, even in this case, the plate-shaped main body 21 in the horizontal ground 3 exists below the gap L, and the gap extending downward does not exist.

If the ends of the engagement pieces 18, 18 are brought into contact with each other, the generation of the gap can be completely eliminated.

Therefore, it is possible to prevent small tools, stoppers, debris, dust, and other small articles from falling down.

As shown in another embodiment of FIG. 10, the horizontal material 3 is composed of a frame made of a plate material having a T-shaped cross section, and has one plate-shaped main body 21a in the vertical direction and the plate-shaped main body 21a. It may be provided with a support plate 22a provided at the upper end.

In this case, the upper surface of the support plate 22a can directly face the lower part of the gap L, and the downward gap can be eliminated.

Next, a connecting method for connecting the frame body 10 to the buildings 1, 2 and a connecting member will be described with reference to FIGS. 5, 6 and 7.

As described above, the construction sites 1 and 2 are provided with the flange 20, and the flange 20 has a disk-shaped flange body 20a and a dovetail-shaped groove integrally provided on the outer periphery of the flange body 20a. And a hooking portion 20b formed of an engagement ring.

On the other hand, a hole 29 penetrating in the horizontal direction is formed in the lower portion of the left and right vertical columns 11, 12 constituting the frame body 10, and a lock piece 30 is inserted in the hole 29 from the horizontal direction. Hook 31 provided at the tip of this lock piece 30
Are engaged with the hooking portions 20b of the flange 20 to form a pair of vertical wedge insertion holes 33 formed in the body 32 of the lock piece 30.
When the wedge 34 is driven in, the wedge 34 pulls the lock piece 30 and the vertical columns 11 and 12 are attached to the flange 20.
Press on the outer surface of and tighten.

Therefore, the flange 20 and the lock piece 3
