Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable scaffolding device used for constructing and repairing a high-rise building and for concrete construction of the building.

[0002]

2. Description of the Related Art Conventionally, a single-layer type scaffolding device has been the mainstream of scaffolding devices for construction, and when it is used for a high-rise building, it is manually assembled and used in multiple layers. But,
There is a problem that it takes man-hours to assemble.

[0003]

SUMMARY OF THE INVENTION In view of the above situation, the present invention requires less man-hours for assembling, and when the scaffolding device is folded, the scaffolding device is folded at the center portion of the length of the floorboard to be folded more compactly. The present invention is made to provide a folding scaffolding device that can be used.

[0004]

SUMMARY OF THE INVENTION The present invention provides four side-by-side arrangements.
In a scaffolding device in which scaffolding members in which floor plates are erected in a multi-tiered manner between the building pipes of a book can be vertically fitted and integrated, a floor plate and joists are divided into two in the central part, and in the central part,
The fulcrum outer plate fixed to one joist and the fulcrum inner plate fixed to the other joist are rotatably attached, and at the end,
A foldable scaffolding device characterized in that a floor plate and joists are configured to be rotatable with respect to a horizontal member and a scaffold member is folded at the center of the floor board and joists.

[0005]

The structure and operation of the present invention will be described below with reference to the drawings. As shown in FIG. 2, the scaffolding device is constructed by bridging the cross members 2 and joists 4 in three steps between four building pipes 1,
Floor plates 5a and 5b are placed on the scaffolding member, and a member made of a handrail 6 and a handrail reinforcement 7 is attached to a building pipe 1 and a joist 4 as shown in FIGS. The scaffold member is a device that is vertically fitted and joined via a joint 18 attached to the building pipe 1. In the present invention, the floorboards 5a, 5b and the joists 4 can be folded at the central portion, and the scaffolding member can be stored compactly.
As shown in FIGS. 1 and 2, the floorboards 5a and 5b and the joists 4 are divided into two parts at the center, and the handrail 6 and the handrail reinforcement 7 are provided.
After removing the member consisting of, it can be folded and stored compactly as shown in FIG.

The structure and operation of the central portion of the floorboard and joists will now be described in detail with reference to FIGS. 5 and 6. Figure 5
2 is a detailed front view of part A of FIG. 2, and FIG. 6 is a detailed plan view of part A of FIG. A fulcrum outer plate 8 is attached to one joist 4a divided into two.
Fulcrum shaft 1 that is fixedly mounted and that serves as the rotation axis
7 is fixed. The fulcrum inner plate 9 is fixed to the other divided joist 4b, and the gravity lock 12 is fixed to the fulcrum shaft 17. The opposite side has the same structure. The floor boards 5a and 5b divided into two are placed on joists 4a and 4b, respectively. The gravity lock 12 may be provided on the same axis as the fulcrum shaft 17.

On the other hand, the ends of the floorboard and joists are shown in FIGS.
Follow the instructions below. 7 is a detailed front view of the B section of FIG. 2, and FIG. 8 is a detailed plan view of the B section of FIG. A floor plate and joists are structured to be rotatable with respect to the horizontal member 2 by using a half-moon plate or a clamp plate 13. The scaffolding member according to the present invention having the above-described structure can be folded at the center portion in the length direction of the floorboard and joists,
It is more compact and lighter when folded than conventional folding scaffolding devices.

[0008]

EXAMPLES Examples of the folding scaffolding device according to the present invention will be described below. A scaffolding member with a construction pipe length of about 5375 mm, joist length of about 2000 mm, and horizontal bridge material length of about 880 mm. A floor board divided in two in the joist direction is laid in three stages, and a member consisting of handrails and handrail reinforcements when used. 6 and 7 are attached to the gravity rock. The floor plate and the center of the joists have the structure shown in FIGS. On the other hand, the ends of the floorboard and joists are rotatable by the meniscus plate or the clamp plate 13 in the structure shown in FIGS. Here, when the scaffolding device is no longer used, the scaffolding devices that are fitted vertically and are disassembled are disassembled with a crane or the like, and members 6 and 7 made of a handrail and a handrail reinforcement material.
Remove and fold from the center of the floorboard and joists as shown in FIG. Therefore, the final thickness after folding is twice the thickness of the building pipe (about 49 mm), and the width is within the length of the horizontal member, and the scaffolding device has a small vertical thickness and can be compactly folded to store the scaffolding device. Convenient for transportation. In addition, even when constructing a site, the scaffolding device is extended and constructed by a lifting device such as a winch, and the scaffolding device is fitted to the upper side to take advantage of the integrated scaffolding device, and the construction of the scaffolding does not require manpower than before. Can be completed.

[0009]

According to the present invention, the floor plate and joists can be folded at the central portion in the longitudinal direction, and the shape thereof can be made extremely compact as compared with the conventional one, so that the storage,
Convenient for transportation. On the other hand, since the members of the scaffolding device of the present invention are integrally incorporated, the construction of the scaffolding can be completed without requiring manpower as compared with the related art.
