Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention mainly relates to a connecting fitting suitable for connecting vertical and horizontal reinforcements of wall formwork.

[Technical background of the invention and its problems] Conventionally, this type of connecting fitting has a tightening bolt attached to a planar U-shaped metal fitting that locks at the intersection of the vertical end and the horizontal end. By tightening, the vertical end and the horizontal end were connected. Therefore, there are disadvantages in that it takes time and effort to tighten the bolts, and the tightening force tends to be uneven, making it difficult to uniformly tighten each part of the connection.

[Purpose of the invention] Therefore, this invention was devised to solve the above-mentioned inconvenience, and it is possible to connect the intersection part of the vertical end piece and the horizontal end piece very easily, and moreover, it has a reliable tightening force. The purpose is to provide a connecting fitting that provides the following.

[Summary of the invention] In order to achieve the above-mentioned object, this invention is a connecting fitting that connects a vertical member and a horizontal member that intersect at right angles. Form a locking fitting consisting of a pair of arm parts that fit on the side surfaces of the intersecting part, and a connecting piece that connects the arm parts, and extend the tip of the arm part to lock it to the side surface of the other connecting member. By forming horizontal hook-shaped horizontal member locking pieces and inserting specified wedges into wedge insertion holes drilled at the base end of each arm to tighten the vertical members and the horizontal members, it is possible to prevent pipes from crossing each other. It became possible to fix parts easily.

[Embodiments of the invention] Hereinafter, embodiments of the invention will be described in detail with reference to the drawings.

Reference numeral 1 shown in the figure is a locking metal fitting, in which a band-shaped metal plate is bent into a substantially U-shape in plan, and a pair of arm portions 2 facing each other in parallel are connected by a connecting piece 5. The spacing between the arm parts 2 is set to a length that allows the insertion of square pipes, etc. that make up the end pieces, etc., and each end of the arm parts 2 is extended downward to connect connecting pieces such as horizontal end pieces. A cross member locking piece 3 is provided to lock the cross member locking piece 3. The arm portion 2 in the illustrated example is made of a 4.5 mm thick steel plate with an interval of 65 mm, and the locking portion of the cross member locking piece 3 is the width of the side surface of the cross member B, which is made of a square pipe with a width of 60 mm. It is formed to lock the entire length. In addition, in the illustrated example, the cross member locking piece 3 is engaged from above the cross member B, but
The locking state of the locking metal fitting 1 is not limited to this, and the locking metal fitting 1 may be attached to the cross member B, and the cross member locking piece 3 may be locked to the side surface of the vertical member A. Furthermore, by changing the connecting material abutting edge of the cross member locking piece 3 from the linear shape shown in the illustrated example to a circular arc shape, circular pipes, etc. can be tightened, and the roots of shoring using pipe supports etc. can be tightened. It can also be used as a clamp or the like (not shown).

A wedge insertion hole 4 into which a predetermined wedge body 6 is inserted is formed at the base end of each arm portion 2 . At this time, the connection angle between the base end of the arm portion 2 of the locking fitting 1 and the connecting piece 5 is bent to match the inclination angle of the wedge body 6, and the side surface of the wedge body 6 is brought into contact with the side surface of one of the connecting members. At the same time, by forming the other side surface of the wedge body 6 to come into contact with the inner surface of the connecting portion of the arm portion 2, the locking fitting 1 of the wedge body 6 and the material to be tightened are fixed in an extremely tight state. can. Therefore, a stable tightening force by the wedge body 6 can be obtained, and deformation of the locking metal fitting 1 and the wedge body 6 can be prevented.

The wedge body 6 is formed by bending a band-shaped metal plate along the longitudinal direction and having a U-shaped cross section. The ends of the bent side plates are brought into contact with the side surfaces of the vertical member A. Further, the wedge body 6 is not limited to the illustrated example, and may be any wedge body as long as it contacts the side surface of the vertical member A and the inner surface of the connecting piece 5 at the same time.

[Effects of the invention] With this invention configured as described above, it is possible to extremely easily connect vertical members and cross members that intersect at right angles.

That is, in a connecting fitting that connects a vertical member A and a horizontal member B that intersect at right angles, a pair of arm portions are formed of a band-shaped metal plate having a substantially U-shape in plan and fit into the side surface of the intersection of one connecting member. 2 and a connecting piece 5 that connects the arm 2, and a side hook-shaped horizontal member that extends the tip of the arm 2 and locks it to the side surface of the other connecting piece. By forming a stopper piece 3 and inserting a predetermined wedge body 6 into the wedge insertion hole 4 drilled at the base end of each arm part 2 to tighten the vertical member A and the horizontal member B, the connection work is made extremely easy. It becomes easy. Moreover, since the wedge body 6 is inserted into the wedge insertion hole 4 of the locking fitting 1 that is locked to the vertical member A and the cross member B, and tightened, each connecting part can be tightened by driving the wedge body 6 with a constant force. The tightening force becomes uniform and stable tightening force can be obtained.
Further, even after use, the locking metal fitting 1 can be removed by simply pulling out the wedge body 6, which has the advantage of shortening the working time for disassembly work.
