Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a pipe support for supporting pipes such as gutters, pipes, and tubular bodies (collectively referred to as pipes in this specification).

[0002]

[Prior art]

 In a conventional pipe support device, a pair of arms having a semicircular arc at the distal end and an opening for mounting a bolt at the base end of the arm are provided side by side, and a nut is fitted to one of the arms so that a screw hole is aligned with the mounting hole. It is known that a pipe is inserted into a circular space in which curved portions overlap each other by welding the ends of arms to each other. The tube support band is welded with a nut in advance in order to eliminate the trouble of holding the nut with a tool when mounting at a high place. However, alignment work to match the screw hole of the nut with the mounting hole of the arm requires a high degree of precision, so it takes time and if the nut is slightly misaligned, it is inserted into the mounting hole of the arm. The bolt cannot be screwed into the nut, resulting in a defective product.

[Action]

 According to the invention of claims 1, 2 and 3, since the bolts are fixed in advance, it is not necessary to hold the bolts inserted into the holes of the fixing members of the building or the like so as not to move with the tool, and both hands are free. Can be used to screw a nut to a bolt, and workability at high places is good. In the inventions described in 1-3, the bolts are fixed in the mounting holes in the inserted state. By inserting the bolts into the mounting holes, the bolts can be arranged at the correct positions, thereby simplifying the production and the rate of occurrence of defective products. Is greatly reduced.

According to the invention of claims 1 and 2, the tube support comprises a pair of arms, each arm is opened and closed to insert a tube into the space of the curved portion at the tip of the arm, and then a pair of arms is provided. By returning the arms to their original juxtaposition, the present invention can be attached to the pipe. According to the invention of claim 2, since the nut is rotatably mounted to the mounting hole of the arm of the pair of arms to which the bolt is not fixed via the locking piece of the nut, the bolt and the nut are provided. It is in a state, and it is not necessary to prepare bolts and nuts separately. Also, by inserting the locking piece into the mounting hole of the arm, the screw hole of the nut and the mounting hole of the arm coincide, and the nut can be easily and correctly mounted, reducing the incidence of defective products. In the invention according to claims 4 and 5, the rear end of the arm is machined to form a cylindrical mounting hole, and a screw groove is provided on the inner surface of the cylindrical mounting hole, so that the bolt can be screwed. In addition, the rate of occurrence of defective products for which bolts cannot be screwed is small. It should be noted that the bolts are not fixed to the arm.

[Embodiment of the invention]

 In general, a steel material is used as the arm material in the present invention. In general, a pair of arms are pivotally attached to each other by forming a T-shaped protrusion at the tip of one arm and opening a hole at the tip of the other arm into which the T-shaped protrusion is inserted. The two protruding parts are locked to each other to connect them to each other. The work of forming a cylindrical mounting hole at the base end of the arm is generally performed by burring. The locking piece provided on the nut may be molded integrally with the nut or may be welded to the nut. The material of the locking piece is generally made of metal.
