[Detailed description of the device]

[Industrial applications]

 The present invention has a support member obliquely provided from the upper fixed end toward the lower free end so that the pipe can be moved in a plane substantially orthogonal to the axial direction of the pipe. The present invention relates to a supporting device that supports vibration-proof piping.

[0002]

[Prior art]

 For example, in sprinkler piping work, the so-called mechanical joint piping method has become the mainstream instead of the conventional welding method. This is because it was considered that the sprinklers would often need to be activated when vibrations from the earthquake were applied. However, the latter method requires more supporting points for vibration resistance than the general method, because the supporting structure of the pipe itself is flexible. Moreover, this method requires a complicated procedure of deciding a large number of supporting points after the completion of piping, measuring the dimensions of each, making drawings based on them, processing them in the factory, and transporting them to the site for installation. However, there was a problem that the construction period would be prolonged.

[0003]

[Problems to be solved by the device]

 The present invention has been made by paying attention to the above points, and its problem is to reduce the setup and enable the vibration-proof construction to be completed at the same time as the piping construction.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention fits into a support member 11, is movable along its longitudinal direction, and is capable of being tightened at a predetermined position, and a second connecting member 21 attached to the outer periphery of a pipe P. The first coupling tool 21 is attached to the upper portion of the second coupling tool 22 integrally with the fastening means 23 while maintaining a substantially orthogonal relationship.

Embodiment FIG. 1 shows the entire vibration-proof support device for piping according to the present invention. Supporting the pipe P is a support member 11 having a pipe structure, which is movable from an upper fixed end 13 so as to be movable in a plane substantially orthogonal to the axial direction of the pipe P. It is provided obliquely toward the free end 14 below.

Reference numeral 10 is a support tool, which is attached to a slab or other part of a building where a load can be loaded. Reference numeral 12 is a mounting socket for the support member 11, and has a screw 15 for screwing with the screw 14 of the fixed end 13 of the support member 11. The socket 12 is pivotally supported on the bifurcated support piece 16 of the support tool 10 by a support shaft 17, and the support member 11 is attached so as to be swingable within the plane. Reference numeral 18 is a nut, 19 is a mounting hole for the support tool 10, and 12a and 16a are axial holes.

The member 20 that connects the support member 11 and the pipe P is composed of first and second couplers 21 and 22. The first connector 21 is formed in a pipe shape having a diameter slightly larger than the outer diameter of the support member 11 so as to be fitted to the outer side of the support member 11, and has a screw 24 for tightening the support member 11 inserted therein. It has a threaded portion 25 on the upper side.

The second coupler 22 is attached to the outer periphery of the pipe P, and has a configuration in which a pair of arcuate coupling pieces 26 and 27 are pivotally supported by a support shaft 29 so as to be openable and closable. The first connector 21 is integrated with the piece 26 by welding as the fixing means 23. The axial direction of the first coupling tool 21 and the axial direction of the second coupling tool 22 are arranged to intersect at a substantially right angle (see FIG. 3). Reference numerals 26a and 27a denote open / close ends of the tips of both coupling pieces 26 and 27, and 30 denotes a nut screwed to a set screw 28 that is passed through the bolt hole.

When the pipe P is supported by the apparatus according to the present invention configured as described above, first, the dimension from the structure C shown by the slab to the upper end of the pipe P is confirmed (this is referred to as A). 4 (a)), the mounting position D of the support 10 is set within the range of 0.5A to 1.0A (the dimension from the pipe center to the support mounting position is B. FIG. 4 (b)). . At this time, the inclination angle from the vertical is in the range of 25 to 45 °, which is optimal for exhibiting vibration resistance. The length of the supporting member 11 is determined in consideration of the length C of the diagonal line obtained from the dimensions A and B by the Pythagorean theorem.

Since there is the support tool 10 from the point D to the upper end portion 13 of the support material and the lengths thereof are added (FIG. 4C), the first coupling tool 21 of the connecting member 20 is fitted to the support material 21. Inserting and attaching the second coupler 22 to the pipe P completes the pipe support by the device of the present invention (FIG. 4D). In addition, tighten each screw part.

In FIG. 4, reference numeral 31 denotes a suspending tool, which bears the load of the pipe P. As in the case of the general construction method, the device of the present invention is installed between the suspension members 31 at intervals required for construction.

[Effect of device]

 Since the present invention is constructed and operates as described above, it means that the piping work was completed at the same time when the piping was attached to the structure of the building by the device according to the present invention, and the vibration resistant work was carried out. As a result, the work is greatly simplified and the construction period is shortened to about one-third. As a result, the work required on-site is completed on the same day, and it is possible to support pipes with excellent vibration resistance.
