Description

  The present invention relates to a pipe clamp for a temporary building, and more particularly to a pipe clamp for a temporary building used for holding a pipe and fixing the pipes to each other or fixing to a structure such as H steel.

Conventionally, as a pipe clamp for an architectural scaffold, there is one disclosed in Patent Document 1.
JP 2006-177048 A

  Generally, a pipe clamp for connecting a plurality of pipes in a crossing direction used for a temporary building is temporary and does not require permanent use, and can be easily installed and removed. At the same time, the structure is required to be simple and inexpensive.

  However, in the above conventional pipe clamp, the structure is complicated and expensive, and there are protrusions on the outer peripheral surface of the pipe element that sandwiches the pipe. Therefore, in the case of various operations such as stretching an exterior sheet, etc. The protrusions obstruct the sheet tension and may damage the sheet. In addition, the mounting angle of the pipe clamp with respect to the pipe is limited.

  The pipe clamp for a temporary building according to the present invention eliminates the above-mentioned drawbacks.

The pipe clamp for a temporary building according to the present invention comprises one and the other clamp elements and a fastening means for integrally connecting them, and the one clamp element is arranged on a substantially half circumference of a pipe to be sandwiched. One curved clamp part that does not have a protrusion on the outer peripheral surface, curved in an arc shape so as to match, one plate-like clamp part connected to this curved clamp part, and a screw provided on this one plate-like clamp part And a convex portion provided on the pipe clamping surface side of the free end of the one plate-shaped clamp portion, and the other clamp element is substantially the same as the one arc-shaped curved clamp portion. The other curved clamp part of the shape, the other plate-like clamp part connected to the other curved clamp part, and any of the screw hole and bolt hole provided in the other plate-like clamp part It characterized in that it comprises more with the other, and the fulcrum portion brought projecting above the other plate-shaped clamping portion serving as a position opposed to the free end portion of one plate-shaped clamping part above.

  The pipe clamp for a temporary building according to the present invention has a simple structure and is inexpensive, and since there is no protrusion on the outer peripheral surface of the pipe element, it does not cause any trouble in the sheet stretching and the pipe clamp can be attached to any pipe. There is a great effect that it can be fixed at an angle.

  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, the pipe clamp 16 for a temporary building according to the present invention is composed of one and the other clamping elements 7 and 14 and a fastening means 15 having a bolt 10 or the like for connecting them together. To do.

As shown in FIG. 2, the one clamping element 7 has an inner peripheral surface 2 that coincides with the outer peripheral surface of the pipe 1 over approximately half of the outer periphery of the pipe 1 for a temporary building to be clamped, for example, approximately 150 °. One plate-like curved clamp portion 4 having a predetermined width and having no protrusion on the outer peripheral surface 3, and one plate-like clamp portion 5 integrally connected to the one curved clamp portion 4. The screw hole 6 provided in the one plate-shaped clamp portion 5 and the convex portion provided on the pipe holding surface side of the free end of the one plate-shaped clamp portion 5 are configured.

  As shown in FIG. 3, the other clamp element 14 includes the other arcuate curved clamp part 8 having substantially the same shape as the one arcuate curved clamp part 4, and the other curved clamp part 8 integrally connected to the other one. A bolt hole provided in the other plate-like clamp part 9 at a position facing the other plate-like clamp part 9 sufficiently longer than the other plate-like clamp part 5 and the screw hole 6 of the one plate-like clamp part 5. 11 and the free end portion of the other plate-shaped clamp portion 9, the hole 12 serving as a mounting portion to be attached to a bracket clamp or the like, and the other end at a position facing the free end portion of the one plate-shaped clamp portion 5. And a fulcrum portion 13 projecting from the plate-shaped clamp portion 9.

  Since the pipe clamp 16 for a temporary building according to the present invention has the above-described configuration, when used, the pipe 1 is connected by the curved clamp portions 4 and 8 of one and the other clamp elements 7 and 14 as shown in FIG. The bolt 10 is screwed into the screw hole 6 via the bolt hole 11 to fix the pipe clamp 16 to the pipe 1, and the pipe clamp 16 is fixed to the fixed structure or the like via the mounting hole 12. To do. According to this, the pipe clamp 16 can be fixed to the pipe 1 at an arbitrary angle.

  For example, as shown in FIG. 5, a pipe clamp 16 fixed to the pipe 1 can be fixed to a placket clamp 17 fixed to a pipe 1 a oriented so as to cross the pipe 1.

  When releasing the pipe 1, the bolt 10 is loosened from the screw hole 6, and the other clamp element 14 is tilted relative to the one clamp element 7 with the fulcrum portion 13 as a fulcrum, thereby the one and the other curved clamps. A large gap 18 is formed between the portions 4 and 8 as shown in FIG. 4 so that the pipe 1 can be easily detached from the pipe clamp 16.

It is an assembly drawing of the pipe clamp for temporary buildings of this invention. It is a perspective view of one clamp element in the pipe clamp for temporary buildings shown in FIG. It is a perspective view of the other clamp element of the pipe clamp for temporary buildings shown in FIG. It is a use condition explanatory view of the pipe clamp for temporary buildings shown in FIG. It is a use condition explanatory view of the pipe clamp for temporary buildings shown in FIG.
