BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting device used for mounting a scaffolding pipe or a handrail pipe attached to a scaffold to a flange portion of a steel frame, and more particularly to a holding member such as the flange. The present invention relates to a pipe clamp mounting device in which a pipe clamp for fixing a scaffold pipe or the like is mounted on a U-shaped clamp portion to be able to change its direction by 90 degrees.

2. Description of the Related Art As a conventional pipe clamp mounting device of this type, as described in Japanese Utility Model Laid-Open No. 60-1841, a right angle of a U-shaped main body constituting a U-shaped clamp portion is known. One type, in which one pipe clamp is replaced on one outer surface, and, as described in Japanese Utility Model Publication No. 3-10282, a pipe clamp is pivotally mounted on a corner of the U-shaped body so as to be rotatable around a support shaft. There is a case where the mounting angle of the pipe clamp can be changed within the range of 90 degrees by wearing it. However, the former replacement type not only requires time and effort to use, but also loses the bolt and nut for mounting the pipe clamp. There is also a risk that they cannot be fully utilized. Also, the latter pivotal type is not practical because it requires sufficient strength so that the U-shaped main body and the bearing portion of the pipe clamp are not deformed by the load applied during use.

[0017]

According to the pipe clamp mounting device of the present invention which can be implemented as described above, the pipe clamp is not replaced on the two side faces of the U-shaped main body constituting the U-shaped clamp portion. The direction can be changed according to the purpose of use by swinging the pipe clamp within a range of 90 degrees with respect to the main body, but the pipe clamp disposed outside the U-shaped main body and the U-shaped main body can be changed. The positioning member disposed inside is connected to each other via a connecting portion penetrating a through hole formed in a corner portion between one side wall portion and the connecting wall portion of the U-shaped main body, and the connecting portion is centered. The positioning member is swung within a range of approximately 90 degrees as follows.
A first position in which the end surface of the clamped member fastened by the fastening screw shaft and the connecting wall portion of the U-shaped main body are clamped and fixed; and a side surface of the clamped member fastened by the fastening screw shaft. It is configured to be switchable to a second position in which it is sandwiched and fixed between one side wall of the shaped body, and a pipe clamp is attached to a U-shaped body as in a conventional pipe clamp mounting device of this type. It does not have a pivot that pivotally attaches, that is, a pivot center axis of the pipe clamp.

Therefore, it is not necessary to secure a thick portion for supporting the pipe clamp with sufficient supporting strength at the corner of the U-shaped main body, and it is formed by pressing the plate material as shown in the embodiment. Even if it is a U-shaped body,
It can be carried out without a problem in strength, and the bearing is deformed by the load concentrated on the bearing for pivotally connecting the U-shaped main body and the pipe clamp as in the conventional case, so that a smooth pipe clamp can be formed. There is no danger that the orientation cannot be changed.

Further, according to the configuration of the present invention, the direction of the pipe clamp is such that the positioning member positioned inside the U-shaped main body is positioned between the side wall portion or the connecting wall portion of the U-shaped main body and the to-be-clamped member. Since it is fixed by being sandwiched between, it is possible to fix the direction of the pipe clamp extremely stably, and since there is no bearing part requiring processing accuracy, it is easy to manufacture and relatively inexpensive. You can do it.

Further, according to the configuration of the present invention, the pipe clamp attached to the outer end of the connecting portion has a pipe clamp mounting seat connected to the outer end of the connecting portion and a pipe clamp bottom portion. Utilizing the detent fitting portions provided at an interval of degrees, the orientation can be changed by 90 degrees around the axial direction of the connecting portion (axial direction of the fixing screw shaft), and positioning with respect to the U-shaped main body. In combination with the change of the direction of the pipe clamp accompanied by the 90-degree swing of the member, the pipe can be mounted in an optimal direction according to the purpose of use of the pipe to be mounted.

According to a second aspect of the present invention, a projection is formed on the U-shaped main body so as to project outward, and the thickness of the positioning member is made substantially equal to the depth of the inner recess of the projection. In a case where the positioning member in each of the first and second postures is configured to fit into the inner concave portion of the protruding portion,
Preventing an unreasonable external force from acting on the positioning member, the direction of the pipe clamp can be fixed more stably, and the strength of the U-shaped body is also increased,
Furthermore, the clamped member fitted into the U-shaped main body can be brought into contact with the side wall portion or the connection wall portion of the U-shaped main body located on both sides of the inner concave portion, thereby accurately positioning the clamped member. be able to.

According to the third aspect of the present invention, it is easier to manufacture the pipe clamp mounting seat than in the case where the pipe clamp mounting seat must be integrally formed with the connecting portion, and the pipe clamp mounting seat is connected. The means for fixing to the part and the means for fixing the pipe clamp to the pipe clamp mounting seat can be shared by a single fixing screw shaft, which can be implemented at low cost.
