Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pipe support for attaching piping such as copper pipes to a building.

[Prior art and its problems]

Generally, when attaching a copper pipe for refrigerant gas distribution in a cooling system to a building, a pipe support is used, and this support allows the pipe to be attached to a mounting board such as an angle installed in the building. It is installed.

Conventionally, as this type of pipe support, for example, a fixing device disclosed in Japanese Utility Model Application Publication No. 52-168310 and a fixture disclosed in Japanese Utility Model Application Publication No. 55-168784 are known, and both of them include: A ring-shaped support band part that holds the circumferential surface of the pipe and has both ends facing each other with a predetermined interval, and holes that extend radially outward from both ends of this support band part and are formed in the mounting board. and a pair of claws that are inserted into and locked into the section.

By the way, such a conventional pipe support requires a certain degree of elasticity since the claw portion is inserted into the hole and locked, and thus must be manufactured by molding synthetic resin.

However, since copper pipes used in cooling systems are usually quite heavy, synthetic resin materials cannot ensure sufficient strength, and supports made of metal such as stainless steel are indispensable.

However, in the case of metal materials, it is difficult to ensure the elasticity of the claws because they are manufactured by processing plate materials.Moreover, because of the plate materials, it is difficult to obtain a structure for the claws that locks securely and stably. There was a problem that I couldn't do it.

The present invention aims to provide a pipe support that solves the problems existing in the prior art.

[Means for solving problems]

The present invention includes a ring-shaped support band part 2 that holds the circumferential surface of the pipe and has both ends facing each other at a predetermined interval, and a ring-shaped support band part 2 that extends radially outward from both ends of the support band part 2 and is attached to the ring-shaped support band part 2. When configuring a pipe support comprising a pair of claws 3 and 4 that are inserted into and locked into a hole H formed in a substrate, the cylindrical elastic material disposed between the pipe 12 and the support band part 2 is particularly useful. The member 13 is provided, and the support band portion 2 and the pair of claw portions 3, 4 are integrally formed from a metal plate material, and each of the claw portions 3, 4 has a peak portion 3a formed by a longitudinal fold line approximately at the center of opposing surfaces. 4a, the support body 1 is provided with four locking points for the hole H, respectively, in the radial direction. Note that it is desirable that the step portions 7 of the claw portions 3, 4 that can be locked to the hole H are formed at an angle.

[Effect]

Next, the operation of the present invention will be explained.

According to the pipe support according to the present invention, the pipe 1
2 is held by the support band portion 2 via the cylindrical elastic member 13.

On the other hand, the claws 3 and 4 integral with the support band part 2 resist the elasticity of the cylindrical elastic member 13 and press against the holes H of the mounting board.
As a result, the claws 3 and 4 lock onto the edge of the hole H. At this time, the claws 3 and 4 are urged in the direction of expansion by the elastic force of the cylindrical elastic member 13, and the claws 3 and 4 are pressed against the hole H.

In addition, since peaks 3a and 4a formed by longitudinal fold lines are provided at the centers of opposing surfaces of each of the claws 3 and 4, four locking points are created that lock onto the hole H in the radial direction.

With the above, the pipe support is reliably prevented from coming off and is stably fixed. In addition, the claw parts 3, 4
Since the step portions 7 that can be locked to the holes H are inclined, they can be locked securely even if the thickness of the mounting board is different.

〔Example〕

Preferred embodiments of the present invention will be described below in detail with reference to the drawings.

First, the structure of the pipe support will be explained.

The pipe support includes a support main body 1 and a cylindrical elastic member 1.
The support main body 1 consists of a support band part 2 and a pair of claw parts 3 and 4 provided at both ends of the support band part 2. In this case, the support main body 1 can be integrally formed by punching out a metal plate material such as stainless steel using a press or the like.

The support band portion 2 has a predetermined width, is curved in the longitudinal direction to form a circular ring shape, and both end portions 2s and 2t are opposed to each other with a predetermined interval. Note that it is desirable that the support band portion 2 has appropriate elasticity.

On the other hand, the claw portions 3 and 4 are bent approximately at right angles in the radial direction from the center of each of the respective end portions 2s and 2t. One claw portion 3 (same as the claw portion 4) is continuous from the end portion 2s and is formed to have a relatively narrow width, and its length in the extending direction is approximately the same as the thickness of the angle 10 that is the mounting board. The extended portion 5 and the extended portion 5
The claw main body part 6 is continuous with the distal end thereof and is formed wider than the width of the extension part 5, and is gradually narrower toward the distal end so as to be easily inserted into the circular hole 11 of the angle 10. In addition, as shown in FIG.
A peak portion 3a is formed approximately at the center of the opposing surfaces of the groove 3a, which is bent approximately at right angles along a longitudinal fold line. As a result, the respective locking positions of the claws inserted into the circular hole 11 are at the four-quarter positions of the circular hole 11, and the locking direction is in the radial direction, so that locking and fixing can be achieved most stably (see Fig. 5). reference). Further, a stepped portion 7 is formed between the extension portion 5 and the claw body portion 6, and this stepped portion 7 is inclined as shown in Fig. 6, thereby allowing attachment to angles 11 of different thicknesses. Make it. The imaginary line in the figure shows the state in which the angle 10p, which is thicker than the angle 10, is locked. Note that a rib portion 8 that bulges outward can be formed between the extending portion 5 and the support band portion 2.

Next, a method of using this support will be explained with reference to FIGS. 7 to 9. FIGS. 7 to 9 are front views showing how to use the device in sequence.

First, the cylindrical elastic member 13 is attached to the copper pipe 12. The elastic member 13 is cut at one point and wound around the copper pipe 12 to be attached. This elastic member 1
3 is usually inserted for the purpose of preventing electrolytic corrosion of the copper pipe 12 and preventing physical damage caused by vibration.
Heat-resistant rubber, etc. can be used. Note that the support according to the present invention is attached using the elastic force of the elastic member 13.

Next, as shown in FIG. 7, the support band part 2 is fitted onto the outer periphery of the elastic member 13 by separating the claw parts 3 and 4 of the support main body 1.

Then, as shown in FIG. 8, one of the claws 3) (or 4)) is inserted into the circular hole 11 previously formed in the angle 10 with a drill or the like, and then, as shown in FIG. Resisting the elastic force of the member 13, insert the remaining claw portion 4) (or 3)) into the circular hole 11. This completes the installation of the main support, that is, the installation of the copper pipe 12. In the attached state, the claws 3 and 4 are pushed in the expanding direction by the elastic force of the elastic member 13, so that they are securely locked to the edge of the circular hole 11. In this state, even if an external force is applied to the copper pipe 12, it is securely fixed without any movement, and moreover, the pipe support will not come out of the circular hole 11.

FIG. 10 shows a front view of a pipe support according to a modified embodiment of the present invention. In addition, in this figure, the same parts as in FIG. 1 are given the same reference numerals to clarify the structure, and detailed explanation thereof will be omitted.

In the embodiment of FIG. 1, the support band portion 2 is curved in a circular shape, but in this modified embodiment, the support band portion 2
is bent into an arbitrary polygon (octagon in the drawing), thereby preventing the elastic member 13 from coming off and increasing the supporting strength of the copper pipe 11.

Although the embodiments have been described in detail above, the present invention is not limited to these embodiments.
For example, the shape and number of the claw portion and the support band portion are not limited as long as they perform the same function. Furthermore, in addition to stainless steel, any metal material such as steel can be used as the material. Furthermore, the pipe can support any pipe such as a water pipe or a gas pipe. Other changes may be made in the detailed shape, configuration, etc., without departing from the spirit of the present invention.

[Effect of idea]

As described above, the pipe support according to the present invention includes a cylindrical elastic member disposed between the pipe and the support band section 2, and the support band section and the pair of claw sections are integrally formed of a metal plate material, and each claw section By providing a mountain portion formed by a longitudinal fold line approximately in the center of the opposing surfaces of the support body, each of the four locking points for the hole portion locks in the radial direction. get the effect.

Since a metal material is used, sufficient strength can be obtained, and the use of a cylindrical elastic member and the special shape of the claws ensure that even plate materials can be fixed reliably and stably.

Since the stepped portion of the claw portion that can be locked into the hole is inclined, it can be suitably adapted even if the thickness of the mounting substrate is different, and versatility can be improved.
