Description

[Detailed description of the invention] The present invention has a first clamping piece that can be inserted between wall panels and a second clamping piece that are linked to a screw shaft so that they can be approached and removed, making it easy and reliable. This article relates to scaffolding and wall connecting fittings (hereinafter referred to as fittings) that can connect wall connecting materials attached to scaffolding, improve the rigidity of the scaffold, and help stabilize it and prevent it from collapsing. I will explain based on this.

In the figure, the metal fitting 1 of the present invention has a first clamping piece 2.
and a second clamping piece 3 are connected to each other by a screw shaft 4 in such a way that they can be approached and separated, and the metal fitting 1 is connected by using a gap 7 between wall panels 5, 5, which is used in a prefabricated building, for example. Fixed. The wall panel 5 is made by joining a frame material 9 into a rectangular shape, and has surface materials 10 and 1 on the front and back sides of the frame material 9.
1 and the wall panels 5 are placed side by side with the space 7 in between as described above. The first clamping piece 2 is
It is a long piece body having a length exceeding 7 and a width of 7 or less, into which the small diameter portion 12 formed at the tip of the screw shaft 4 is inserted into the center, and the tip By caulking, the first clamping piece 2 is fixed to the screw shaft 4. Note that it may be fixed by welding or the like. In this embodiment, the second clamping piece 3 is a long piece having the same shape as the first clamping piece 2, and has a through hole 13 bored in its center, and the screw shaft 4 is inserted into the through hole.
3 and on the outer surface of the second clamping piece 3,
A nut 14 is screwed onto the screw shaft 4. Further, a threaded portion 16 is provided at the outer end of the threaded shaft 4. The threaded portion 16 is, for example, an internal thread concentric with the screw shaft 4, and is carved into a hexagonal portion 17 expanded at the outer end of the screw shaft 4. The other end of the wall connecting material 21, which is fixed using the clamp 20, is screwed together. In the wall connecting material 21, a right-handed threaded shaft 22 and a left-handed threaded shaft 23 are screwed into a turnpackle 24, and the right-handed threaded shaft 22 is screwed into the threaded portion 16. Further, a nut 25 is fixed to the right-hand threaded shaft 22 using a set screw, and the right-hand threaded shaft 22 can be rotated by the nut 25.

However, in the metal fitting 1 of the present invention, the first clamping piece 2 is
By making the longitudinal axis vertical, inserting it into the spacer 7, and rotating it 90 degrees, it can be locked to the panel 10 on the indoor side of the wall panel 5, and the second clamping piece 3 can be attached to the panel 10 on the indoor side of the wall panel 5. By tightening the nut 14 while in contact with the first and second clamping pieces 2 and 3,
By compressing and holding the wall panel 5, the metal fittings 1 can be easily and reliably fixed. Therefore, scaffolding 19
Right-hand screw 2 of the wall connecting material 21 with one end fixed
2 into the threaded part 16 using the nut 25, the scaffold 19 can be firmly connected to the wall panel 5 via the wall connecting material 21 and the metal fittings 1, and the scaffold 19
The mounting strength of the structure can be increased and stabilized, and since the rigidity is improved, it is possible to reliably prevent the structure from collapsing.

As mentioned above, the metal fitting of the present invention has a first clamping piece that can be inserted between the wall panels, and a second clamping piece that can be moved closer to and away from the second clamping piece by linking with the screw shaft. The screws can be securely fixed to the wall panel, and the threaded part at the end of the screw shaft allows the wall connecting material to be easily and firmly fixed, making it possible to stabilize the scaffolding, improve its rigidity, and prevent it from collapsing. be effective.

In addition, in the metal fitting of the present invention, the screw shaft and the first clamping piece may be made rotatable, and the second clamping piece and the screw shaft may be held relatively rotatably, and the screw shaft and the first clamping piece may be held rotatably. By screwing them together, they can be transformed into various shapes, such as those that move them closer together as the screw shaft rotates, and the second clamping piece can span a square, circular, etc. wall panel and come into contact with its face material. If so, it can be configured into various shapes.
