Description

Attachable and detachable clamps for gas meters that are easy to attach and detach.

The present invention relates to a clamp for gas meter piping that is easy to detach and attach, which can fix a clamp to a wall surface and a gas piping simply and firmly without any additional equipment.

City gas supplied to multi-family houses or private homes is usually installed in a main supply pipe buried in the underground, and flows into the house. Branches branched from the main supply pipe are installed on the wall of the building for several times, It is connected to the gas piping and enters the inside of the house. It is common that the branch pipes or gas pipelines exposed to the underground buildings are fixedly installed on the outer wall of the building for several times. The gas pipes exposed to the outside must be prevented from corrosion for a long period of time, Should be installed so that it is blocked.

In a conventional method of fixing a branch pipe or a gas pipe to the building wall, a bracket 2 for fixing the gas pipe 1 at a predetermined distance from the building wall as shown in FIG. And the gas piping 1 is fixed to the top of the plurality of brackets 2 by means of the U bolts 3 and the fixing nuts 5.

In the conventional method, an insulating tape is wound around the contact portion of the gas pipe to prevent corrosion and current conduction due to the contact friction between the metal chain bracket and the gas pipe and the U bolt, and then the U bolt is fixed to the bracket . However, since the above work is performed in the building wall, it is difficult to wind the insulation tape around the contact portion of the gas pipe, and the operation is continued in a state in which the operation of winding the insulation tape is not performed in some parts, And electric current is caused to flow due to a short circuit, so that safety is not guaranteed. In addition, the conventional method does not effectively prevent contact friction and flow with the bracket, and the insulating tape wound on the gas pipe does not effectively prevent the flow, and the operation method of tightening the fixing nut again by inserting the U bolt into the bracket causes a delay of the working time.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a clamp for clamping a socket, which is inserted into a recessed portion formed on a rear portion of a clamp, It is possible to fix the gas pipe easily and firmly, and the gas pipe can be more firmly fixed by using the fixing part provided with the rubber packing on the inner circumference, so that the safety accident caused by the gas leakage can be prevented in advance, Which is easily detachable and attachable to the gas meter when the gas meter is replaced.

Further, a hook portion is formed at one end of the first fixing portion and a hooking groove is formed at one end of the second fixing portion, so that the front surface portion and the rear surface portion of the clamp can be easily and firmly combined with the one- Another object of the present invention is to provide a clamp for piping which can be easily fixed to and detached from a gas meter.

In order to solve the above-mentioned problem, the present invention is characterized in that it comprises a first recessed portion provided on one or more inner surfaces of a first body portion formed on a first front surface portion of the upper clamp and a second recessed portion formed on one side and the other side of the first front portion A first fixing part for fixing a front surface of the gas pipe by having a rubber packing on an inner circumferential surface thereof, a first flange part formed at an end of the first fixing part and having a first through- A first rear portion having one or more first insertion portions on the inner surface of the second body so as to be inserted and fixed in the first recessed portion and a second rear portion formed on one side and the other side of the first rear portion, A second fixing part having a rubber packing on an inner circumferential surface thereof to fix a rear surface of the gas pipe; a second flange formed on an end of the second fixing part and having a second through hole of a thread; And the first through hole and the second through hole are connected to the fastening bolt And a second front surface portion and a second rear surface portion of the lower clamp are connected to the first front surface of the upper clamp And a first rear surface portion of the second rear surface portion is formed with a bracket having one or more reinforcing bars on an upper surface thereof. The bracket is bent downward at one end, And a second insertion portion formed at one end of the bracket and a second insertion portion formed at one end of the bracket, and the second insertion portion is formed at one end of the bracket, The second rear surface portion can be attached and detached in a sliding manner, and the problem is solved by using the locator bolt as the fastening bolt.

In addition, the first fixing portion forms a hooking portion at one end thereof, and the second fixing portion forms a hooking groove at one end thereof, and fixes the front and rear portions thereof by fixing the front and rear portions thereof.

According to the present invention, the front part can be coupled to the rear part without the need for additional equipment, thereby reducing the time consuming installation and increasing the efficiency of the operation. Further, the through hole of the flange part is further formed, There is an effect that can be fixed.

Also, the structure of the bracket fixed to the rear part of the lower clamp and the wall can be easily detached, so that it is easy to repair the clamp, and a reinforcing bar is further formed on the upper face of the bracket so that the clamp attached to the gas pipe and the bracket provided on the wall are firmly fixed And the like.
