DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention can prevent the upper scaffold floor plate of a working suspended scaffold from moving away from the scaffold base, such as floating.
Appearance of suspended scaffolding by eliminating gaps between adjacent scaffold floor boards,
In particular, the present invention relates to a suspended scaffolding structure and a floor panel connecting member for a suspended scaffold capable of improving the appearance from the ground.

[0002]

2. Description of the Related Art Conventionally, in the construction and repair work of a structure such as a bridge on a highway, for example, a suspension scaffold for work is generally provided under the structure. Specifically, on the ground, as shown in FIG.
A scaffold floor plate (33) is placed in parallel on a scaffold base (32) in which the main beams (30) and the cross beams (31) are cross-connected, and at the top of the main beams (30). A connecting rod (35) made of a metal pipe is inserted into a fixed ring (34) projecting at a predetermined interval to form a suspension scaffold, which is then lifted by a crane or the like, and used as a bridge on an expressway. And suspended and fixed below the structure by a suspending fitting or the like.

[0003]

However, in the above-mentioned conventional suspended scaffold structure, the scaffold floor plate (33) is merely placed on the scaffold base (32), and the connecting rod (3) is also provided.
Since a gap is provided between the scaffold floor plate (33) and the connecting rod (35) in order to smoothly insert the fixing ring (34) into the fixing ring (34), the scaffold floor plate (33) is vertically moved. In addition, there is a problem that the scaffold floor plate (33) rises particularly in strong winds. In addition, a loud contact sound generated when the scaffold floor plate (33) comes up and comes into contact with the connecting rod (35) due to a strong wind or the like is often complained as a noise pollution around a residential area.

Further, adjacent scaffold floor boards (33) (33)
It is inevitable that a gap is formed between them, and there is also a problem that appearance when viewed from the ground is not good.
In particular, in the case where a blue sheet (42) is laid on the scaffolding floorboard (33) in order to prevent the coating liquid from adhering at the time of painting, when the scaffolding floorboard (33) is viewed from above the ground. The blue portion visible from the gap between () and (33) was conspicuous, and did not match the surrounding scenery at all.

The present invention has been made in view of such technical background, and it is possible to prevent an upper scaffold floor plate in a working suspended scaffold from moving away from the scaffold base, such as floating. An object of the present invention is to provide a suspended scaffolding structure and a suspended scaffolding floor panel connecting member capable of eliminating a gap between adjacent scaffold floor boards and improving the appearance of the suspended scaffold, particularly the appearance from the ground.

[0006]

Means for Solving the Problems In order to achieve the above object, the present inventors have conducted intensive studies and found that a floor plate connecting member provided with a fixing ring insertion hole in the length direction is attached to the fixing ring through the fixing ring. Is inserted between the adjacent scaffold floor plates over the main beam in a state where the floor plate connecting member is inserted, and the upward displacement of the floor plate connecting member is regulated by the connecting rod inserted through the plurality of fixing rings. It has been found that the present invention has a suspended scaffold structure, and the present invention has been completed.

In other words, the hanging scaffold structure according to the present invention is formed between the adjacent main beams on the upper surface of the scaffold base formed by cross-connecting the cross beams and the main beams having fixing rings projecting at predetermined intervals at the top. A scaffold floorboard is laid in the provided laying recess, and a floor plate connecting member provided with fixing ring insertion holes at predetermined intervals in the length direction straddles the main beam in a state where the fixing ring is inserted through the insertion hole. The connecting rods are inserted over a plurality of fixing rings arranged and arranged in the width direction of the main beam, being bridged and placed between adjacent edges of the upper surface of the adjacent scaffold floorboard, and the connecting rods are used to connect the floor plate connecting member. It is characterized in that the upward displacement is restricted.

[0008] Since the floor panel connecting members are placed so as to be bridged between the adjacent edges of the upper surface of the adjacent scaffold floor boards, no gap is formed between the adjacent scaffold floor boards even when looking up from the ground. The appearance of the hanging scaffold can be made good. In addition, when attaching the floor plate connecting member, complicated fixing work such as connection and fixing with bolts and nuts is not required, and it is only necessary to mount the floor plate over the main beam in a state where the fixing ring is inserted through the insertion hole. Good, excellent workability. In addition, since the upward displacement of the floor plate connecting member is restricted by the connecting rod disposed on the floor plate connecting member, the upward displacement of the scaffolding floor plate is restricted at both edges in the width direction of the floor plate connecting member. This prevents the scaffold floor plate from rattling in the vertical direction, and prevents the scaffold floor plate from rising even when a strong wind blows. Therefore, no loud contact noise generated by the contact between the scaffold floor plate and the connecting rod is generated, and there is no fear of noise.

[0009] The floor panel connecting member for a suspended scaffold according to the present invention is a rectangular member in plan view made of a hard material,
Fixed ring insertion holes are provided at predetermined intervals in the length direction, and the upper surface is formed as a curved surface or a curved surface that is convex upward in the width direction, while a concave portion is provided on the lower surface and the concave portion is formed in the concave portion. It is characterized in that it is adapted to receive at least a part of the main beam.

Since the fixing ring insertion hole is provided,
Since the mounting is completed simply by placing the fixing ring through the insertion hole and straddling the main beam, the workability is excellent. Further, since the upper surface is formed as a curved surface or a curved surface that is convex upward in the width direction, it is possible to effectively prevent the worker from tripping on the floor plate connecting member. Furthermore, since at least a part of the main beam can be received in the recess provided on the lower surface, the existing components (main beam, cross beam, connecting rod, etc.) based on the conventional standard can be used without any design change as a scaffold structure. ), That is, it is possible to apply the floor plate connecting member to an existing scaffold structure as it is, so that it is extremely excellent in versatility and has the advantage of reducing the cost burden. is there.
