Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold for repairing a bridge railing and a hanging metal fitting for the scaffold.

[0002]

2. Description of the Related Art Conventional repairs for bridge balustrades are generally carried out by a suspension scaffolding method using the bridge body or a combined scaffolding method from a bridge foundation, regardless of the bridge type and type.

In the former method of suspending scaffolding, as shown in the left side of FIG. 12, a concrete anchor B is installed on the bridge body near the ground cover A, a beam is passed between the main girders, and a working chain scaffolding by a suspending chain C is applied to it. 12 is a structure in which D is suspended, and the latter method of constructing scaffolding is a structure in which a frame structure F is formed from logs and pipes from a bridge foundation surface E as shown in the right side of FIG.

The suspension scaffolding method has an advantage that it is not affected by the increase of water in the river and traffic because the whole is occupied in the sky, but the bridge is damaged because the concrete anchors and chains are attached to the main girders and floor slabs. , Has the drawback that it takes time when assembling, and it is dangerous when disassembling,
Since the concrete scaffolding method does not attach concrete anchors or chains to the bridge, it does not damage the bridge, but it cannot be assembled on rivers and overpasses, and even in rivers that can be assembled, driftwood etc. There is a risk of collision, and there is a drawback that elevated roads will hinder traffic on ordinary roads.

[0020]

As described above, the present invention has the following common effects in claim 1, claim 2, and claim 3. The fixing material is fixed on the upper surface of the bridge by the fixing vertical member, and the hanging connecting member of the hanging member is connected by the fixing connecting vertical member,
Since the hanging connection vertical member is connected and fixed to the fixing vertical member by a connection structure that is vertically movable, it is easy to adjust the height of the scaffold by moving the hanging connection vertical member in the vertical direction. Since the fixing vertical member is provided as the fixing material and the hanging fixing vertical member having the bridge lower surface fixing adjustment member is provided as the hanging material, the fixing to the bridge upper surface and the bridge lower surface is ensured and the hanging material is directed toward the bridge side. Since the lower bridge side fixing adjustment member is provided, the fixing to the bridge side surface ensures the fixing in the lateral direction together with the fixing of the fixing material on the bridge side surface of the upper bridge side fixing adjustment member. .

To attach to the bridge, it is sufficient to attach it to the bridge by sandwiching the bridge upper surface and the bridge lower surface with an anchoring material and a suspending material, and since it occupies the sky, concrete anchors and chains found in the conventional suspension scaffolding method are mainly used. It is possible to eliminate the risk of damage to the bridge body due to installation on the girder or floor slab and the risk of dismantling, and to eliminate the danger of collision with driftwood in rivers and the like, which is seen in the combined scaffolding method, and traffic obstacles on general roads.

In the second aspect, the fixing material and the suspending material are integrated to form a suspending metal, and in the third aspect,
Since the fixing material, the hanging material, and the floor board are integrated and configured as a scaffolding, the work at the repair site can be saved.
