By fastening the parts with bolts and nuts, the latching pieces at the tips of the latching parts could be respectively latched and fixed to the inner periphery of the round hole. (For example, see Patent Document 1 or 2)

Japanese Patent Application Laid-Open No. 2011-17382 connects both fitting portions of a pair of left and right main body halves with a spindle, and a coil spring is interposed between the half halves of the main body. A structure is disclosed in which both half halves of the main body are connected and integrated in a state where they are separated from each other by a repulsive force of a coil spring.
That is, when attaching the half of the main body part to the member to be attached, both the insertion parts are pressed, inserted into the hole part in a contracted state, and then released by the repulsive force of the coil spring. There has been disclosed a technique in which the interval is restored to the original position so that it can be temporarily placed on the inner periphery of the hole.

In the above conventional method, a pair of left and right fixing members which are members constituting the fixing bracket, and bolts and nuts for tightening the fastening portions of both fixing members are each single unit, and at the time of mounting, With the pipes attached to the brackets, mounting them while assembling each fixing member, and mounting the tightening bolts and nuts, it takes time and work at high places may cause the pipes and members to fall, etc. Safety cannot be secured.
In Japanese Patent Application Laid-Open No. 2011-17382, the left and right main body halves are connected and integrated by a support shaft, but it is necessary to assemble a separate screw at the time of mounting work, and it takes time and trouble to mount the screw. There is also a possibility.
In addition, although there is an advantage that the fixing tool can be temporarily placed in the hole portion of the attached member by the coil spring interposed in the support shaft, the two main body part halves are opposed to attach the fixing tool to the attached member in advance. There is a problem that the interval between the portions is restricted by the insertion portion inserted into the hole portion of the member to be attached, and there is a possibility that a failure may occur when the pipe is attached.

  The present invention has been made in view of the above-described conventional problems, and its purpose is to connect and integrate the members constituting the fixing bracket, and to easily attach the long material to the mounting bracket without trouble in the integrated state. An object of the present invention is to provide a long material fixing bracket that can be attached and fixed.

  As a means therefor, claim 1 of the present invention is a long material fixing bracket for holding a long material with a pair of fixing members, each fixing member having an arc-shaped holding portion for holding the long material, and one end thereof. A bolt insertion hole provided with a fastening portion extending to the other end and a latching portion extending to the other end and latching to the through hole of the mounting bracket, and a fastening bolt provided in the fastening portion of one fixing member The fastening screw is provided with an elastic material that is screwed and connected to a screw hole provided in the fastening portion of the other fixing member, and urges the fixing members to close to each other. And

  A second aspect of the present invention is characterized in that the elastic material is a coil spring and is externally fitted to a screw shaft of the tightening bolt.

  A third aspect of the present invention is characterized in that the coil spring is conical.

  A fourth aspect of the present invention is characterized in that a protruding piece protruding from the tip of the fastening portion of the other fixing member is formed at the tip of the fastening portion provided with the bolt insertion hole of the fixing member.

According to the long material fixing bracket of the present invention, a screw hole is provided in the fastening portion of one fixing member, a bolt insertion hole is provided in the fastening portion of the other fixing member, a tightening bolt is attached to the bolt insertion hole. By being screwed into and connected to the screw holes, it is possible to integrate them, eliminating the trouble of assembling and improving workability.
Since the fastening screw is provided with an elastic material that urges each fixing member to close to each other, the distance between the opposing gripping parts is smaller than the outer diameter of the long material. The fitting can be temporarily fixed to the pipe by the reaction force of the elastic material.
In the state where the long material is gripped, the interval between the two latching portions becomes wider than the diameter of the through hole of the mounting bracket, so that one latching portion is hung inside the through hole and the other fastening is performed. By expanding the portion in the direction in which the elastic material contracts, the other latching portion is moved toward the latching portion that is hung on the through hole, and the interval between the latching portions is closed. The part can be inserted into the through hole.
After the both latching parts are inserted into the through-holes, the expanded fastening part is restored by the reaction force of the elastic material, so that the latching parts are expanded again and latched on the inner periphery of the through-holes. can do.
That is, since the pipe can be temporarily fixed to the mounting bracket, the tightening bolt can be tightened in a state where the hand is released, so that the workability is good and the safety of the work can be ensured.

  Since the elastic material is a coil spring and is externally fitted to the screw shaft of the tightening bolt, the structure can be simplified and the assembling work at the time of manufacture can be simplified, so that the manufacturing cost can be suppressed.

  Since the coil spring is conical, when the fastening bolt is fastened to fix the pipe, the compressed coil spring has a thickness corresponding to the wire diameter of the spring, so exposure from the gap between the head of the fastening bolt and the fixing member. In addition, it is almost the same as a general round washer in appearance, so it can be used without a sense of incongruity.

  By forming a protruding piece protruding from the tip of the fastening part of the other fixing member at the tip of the fastening part provided with the bolt insertion hole of the fixing member, the elastic material contracts one of the overlapped fastening parts. When expanding in the direction, it is possible to solve the conventional problems such as being easily caught by a finger and improving workability.
