Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a temporary scaffolding at a construction site or a civil engineering site, a pipe for a temporary enclosure, or a clump metal fitting for connecting pipes or other pipes forming a temporary construction body to a plate material such as a steel material.

[0002]

[Prior art]

 This type of clamp metal fittings usually consists of a pair of clamp bodies, such as an orthogonal type or a parallel type in which a pair of clamp bodies are non-rotatably fixed in the orthogonal direction or the parallel direction depending on the place where the pipes are connected. A fixed type clamp and a free type clamp that can freely rotate both clamp bodies are used.

[0003]

[Problems to be solved by the device]

 In the former fixed type clamp, both clamp main bodies are fixed, so when clamping the pipe, it is advantageous in terms of strength and stable, but for example, both are fixed in the orthogonal direction or parallel direction. Since the directionality of the pipe is determined, it has the drawback of narrowing the connection application of the pipe. On the other hand, the latter type of flexible clamp can be freely rotated and clamped regardless of the directionality of the pipes, but when connecting pipes, the clamps will not be visible. Since there is a risk of rotation, there are drawbacks from the viewpoint of safety and the stability of the connection between pipes, and early development of a clamp fitting that solves these problems has been desired.

The present invention is a clamp developed in view of the above-mentioned circumstances, and an object of the present invention is to provide a clamp of a fixed type having a directionality in a perpendicular direction or a parallel direction by a simple structure with a simple structure. The purpose of the present invention is to provide a clamp that can be used for a free-standing type clamp and has excellent strength.

It is rotatably provided via a shaft, and a fixing groove for rotationally fixing is formed on the head end surface of the shaft mounting member, and a positioning locking piece is rotatably provided on the shaft mounting rod provided on the clamp body. The means for locking the locking piece in the fixing groove so as to fix the pair of clamp bodies to each other at an appropriate rotation position is adopted.

In this case, a fixing groove in the X-axis direction and the Y-axis direction is formed on the head end surface of the shaft mounting member, and a locking piece for positioning is undulated to fit the locking piece in an appropriate fixing groove. It is preferable to lock and position the pair of clamp bodies in the orthogonal direction or the parallel direction and fix them. This shaft mounting member has a caulking portion at the lower end of a shaft rod portion having a head portion at one end, and the shaft rod portion is rotatably fitted into a rotation hole formed in one clamp body, while the other is attached. The flat surface of the shaft rod portion is non-rotatably fitted into the engaging hole formed in the clamp body, and the shaft mounting member is fixed to the clamp body by a caulking portion provided at the lower end of the shaft rod portion. In the shaft mounting member, a shaft rod portion having a head at one end is rotatably fitted to a pair of clamp bodies, and a lower end portion of the shaft rod portion is fixed to one clamp body by welding. You may.

When connecting the pipes or the pipes and the plate members to each other, the clamp main body is rotated in the orthogonal direction or the parallel direction, and then fixed in the X-axis direction or the Y-axis direction formed on the head end surface of the shaft mounting member. When the locking piece is undulated in the groove via the shaft-mounting rod and engaged and locked, the rotation of the clamp body is firmly fixed to form a fixed clamp metal fitting, so the pipe is stable. Can be supported by connecting the lock piece to the outer surface of the pipe on the side opposite to the shaft mounting member. Then, the clamp body can be configured as a free-standing clamp fitting without the locking piece getting in the way, and the pipes can be securely connected even in an oblique state.
