Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a scaffolding structure that is installed at a site to perform construction work on the side surfaces or outer walls of a building.

[Prior Art] Conventionally, in this type of scaffolding, the scaffolding boards are held on a frame mainly constructed of round pipes using claw-like latches, but in this method, there is no A large gap is created, which is not desirable from a safety point of view. Further, when connecting the scaffolding boards in the horizontal direction, the round pipe frame members are connected by connecting fittings, but in this case too, a large gap is created between the frame members, which is not desirable from a safety standpoint. Furthermore, when these metal fittings are used, unevenness occurs on the foot surface, which is inconvenient in terms of safety and management.

Further, although it is possible to connect this type of scaffolding in the horizontal direction, it is not suitable to connect this type of scaffolding in the vertical direction because assembly errors at the connecting portions will accumulate.

[Problems to be Solved by the Invention] In consideration of the above facts, the present invention provides a method that allows a plurality of scaffold frames to be connected in close contact with the foot surface without unevenness, and also allows the scaffold frames to be connected in the vertical direction. The purpose is to obtain a scaffolding structure that is possible.

[Means for Solving the Problems] A scaffolding structure according to the present invention includes a plurality of scaffolding frames formed of tubular materials having a rectangular cross section and having first holes and second holes on the sides, and the first hole. A protruding rod that is fitted into the first hole is provided on the side edge, and when the protruding rod is fitted into the first hole, the scaffold plate that is in close contact with the scaffold frame and each of the scaffold frames that are adjacent to each other. Said second
A connecting rod that is fitted into a hole and connects the adjacent scaffold frames in the surface direction of the scaffold board, and the plurality of scaffold frames are removably connected at predetermined intervals in the thickness direction of the scaffold board. The invention is characterized in that it has a long member.

[Operation] The operation of the present invention will be explained through scaffold assembly work.

When a scaffold is formed with a single scaffold frame and a single scaffold board, the protruding rods provided on the side edges of the scaffold board are replaced by the first protrusions provided on the sides of the scaffold frame formed of a tube with a rectangular cross section. Fit it into the hole. In the mated state,
The scaffolding board is tightly attached to the scaffolding frame. This forms a single scaffold.

Next, when connecting a plurality of scaffolds in the plane direction of the scaffold board, first, connecting rods are fitted into respective second holes provided in the sides of mutually adjacent scaffold frames. Thereby, each scaffold frame is connected in the surface direction of the scaffold board. Next, the protruding rods of the scaffolding boards are fitted into the first holes in the sides of each scaffolding frame. As a result, each scaffolding board comes into close contact with each scaffolding frame, similarly to the case described above. As a result, the plurality of scaffolds are connected in the plane direction of the scaffold board.

Next, when connecting multiple scaffolds at predetermined intervals in the thickness direction of the scaffold boards, first insert the protruding rod of the scaffold board into the first hole of the scaffold frame so that the scaffold board is in close contact with the scaffold frame. Let it fit. Thereafter, the plurality of scaffold frames are connected at predetermined intervals in the thickness direction of the scaffold board using elongated members. Thereby, a plurality of scaffolds are connected at predetermined intervals in the thickness direction of the scaffold board. Note that it is also possible to connect a plurality of scaffold frames in the plane direction of the scaffold board and then connect them in the thickness direction of the scaffold board by an elongated member. By doing so, it is possible to improve work efficiency when working on the side walls and outer walls of a building. Further, since the elongated member is removable, the elongated member can be removed and stored when not in use, so that less storage space is required.

FIG. 1 shows an example of a scaffolding structure according to this embodiment. The scaffolding frame 12 disposed on the peripheral edge of the scaffolding board 10 is formed by assembling tubes with a square cross section, and a sleeve 14 cut from the same tube is attached to a part of the scaffolding frame 12 to intersect with the tubes of the scaffolding frame 12. A through hole 16 as a first hole is formed by welding in the direction. Since the length of the sleeve 14 in the hole direction is the same as the width of the tube of the scaffolding frame 12, both open ends of the sleeve 14 coincide with the side surfaces of the scaffolding frame 12.

On the other hand, a square protruding rod 18 is protruded from the side wall of the scaffold board 10 at a position corresponding to the through hole 16 of the sleeve 14, and this protruding rod 18 is fitted into the through hole 16 to close the scaffold board 10. It is adapted to be tightly joined to the scaffolding frame 12. Note that the direction perpendicular to the thickness direction of the scaffold board 10 is the planar direction. Sleeve 14
