Abstract

PURPOSE:To eliminate inconvenience in adjusting gas piping works with interior turnising works. CONSTITUTION:In gas piping works, a movable joint 7 to which a movable pipe 21 is attached is fixed in a box 1 beforehand at the mounting position of a gas cock 26, after finishing interior furnishing works, the movable joint 7 is moved for fixing to a prescribed position by using the movable pipe 21, and the gas cock 26 is attached to the fixed movable joint 7 by using a short pipe 25. Thus, in the case of the interior works, existance of the movable pipe 21 can not only eleminate any chance to forget a mounting hole to be dailled at the mounting position of the gas cock or to shift the prescribed position, but also adjust the position of the movable joint 7 by moving it ahead, and so there is no worry about any trouble such as too much man hour required for mounting of the gas cock due to inferior adjustment between works.

A fixing screw which is inserted from a hole of a fixed plate of the movable joint through a long hole of a sleeve plate of the box, and which fixes the movable joint in the box by a nut plate which abuts against the sleeve plate and the back side of the fixed plate; e. Gas cock mounting device.

[0010]

[Operation] After the gas pipe is connected, the tip of the gas pipe is connected to the pipe connection port of the movable joint. Next, the movable joint is inserted into the box, and the box is screwed to, for example, a curing plate located on the back side of the gas cock attachment position. At this time, the fixing screw is passed through the hole of the fixing plate through the long hole, and the nut plate is screwed into the tip. Next, a moving pipe having a length projecting from the wall surface to the front side is connected to the gas cock connection port of the moving joint.

The above is carried out as the work up to the gas pipe, and then in the interior work, for example, in the case of a bathroom, first the inner wall is stretched, the tile is attached to this surface, and a hole is formed at the moving pipe. To project into the bathroom.

When the gas cock is to be installed after the above-mentioned interior work is completed, first a mounting hole of a predetermined size is made in the interior wall centering on the moving pipe, and then the moving pipe is held by hand and the moving joint is boxed. After sliding inside, the engaging teeth and hooks are engaged, and then the fixing screw is rotated, the nut plate advances and hits the back of the sleeve plate. As a result, the movable joint and the box can be fixed. Next, remove the moving pipe from the moving joint, screw the short pipe through the mounting hole into the gas cock mounting hole of the moving joint, and then cover the mounting pipe with a plate on the wall surface of the short pipe. Attach.

[0013]

1 to 3, reference numeral 1 is a box, and the box 1 has a square shape whose front and rear surfaces and a bottom surface are open, leaving step portions 2 and 2a on both sides.
Formed on both sides of the front are sleeve plates 3 and 3a having long holes 4 and 4a extending in the vertical direction, and fixed parts 5 are formed on the upper center and lower left and right of the rear part. The hooks 6 and 6a are formed on the bottom.

Reference numeral 7 indicates a step portion 2 in the box 1.
A gas coupling having a gas cock connection port 8 formed at the front side and a gas pipe connection port 9 formed at the bottom of the moving joint 7 supported by 2a to be movable in the front-rear direction and the up-down direction. The passage 10 is formed, and fixing plates 11 and 1 with holes 12 and 12a are formed on both front sides.
1a is formed, and further downward rack-shaped engaging teeth 13 and 13a are formed on both side surfaces. The engaging teeth 13 and 13a are engageable with the hooks 6 and 6a from above.

Numerals 14 and 14a are fixing screws for fixing the movable joint 9 to the box 1.
4 and 14a are holes 1 of the fixed plates 11 and 11a of the movable joint 7.
2, 12a to the long holes 4, 4a of the sleeve plate 3, 3a of the box
It can be inserted through and screwed into the screw holes 16 and 16a of the nut plates 15 and 15a behind the sleeve plates 3 and 3a.

As shown in FIG. 4, in the mounting device having the above-mentioned structure, the box 1 is fixed to the curing plate 17 using screws 18, and the flexible gas pipe 19 is connected to the gas pipe connection port 9 of the movable joint 7 via the connection mouthpiece 20. Then, a moving pipe (rod) 21 is screwed into the gas cock connection port 8 and the moving joint 7 is pushed deepest in the box 1.

The inner wall 22 is constructed in this way, and the moving tube 21 is projected on the surface of the inner wall 22 by making a temporary hole 23 through which the moving tube 21 passes.

Next, when mounting the gas cock, as shown in FIG. 5, first, a mounting hole 24 of a predetermined size is formed around the temporary hole 23 of the inner wall 22, and then the projecting moving pipe 21 is attached. Holding the movable joint 7 in the hand from the state shown in FIG. 6 once to bring it to the state shown in FIG. 7, then pull it toward you to move the front side of the movable joint 7 forward to the back side of the inner wall 22. When 21 is lowered, the movable joint 7 is also lowered. At this time, the engaging teeth 13, 13a are engaged with the hooks 6, 6a from above, and the movable joint 7 cannot move in the front-rear direction. In this state, the fixed plates 11, 11a of the movable joints 7, 7a
When the fixing screws 14, 14a inserted through the holes 12, 12a of the sleeve 1 and the long holes 4, 4a of the sleeve plates 3, 3a of the box 1 are rotated, a nut plate 15, on the back side of the sleeve plates 3, 3a,
15a moves forward and hits the backs of the sleeve plates 3 and 3a and stops. As a result, the engagement teeth 13 and 13a and the hooks 6 and 6a are firmly engaged with each other, and cannot easily be disengaged. In the case of the embodiment, the engaging teeth 13 and 13a and the hooks 6 and 6a are inclined rearward to make the fixation stronger.

Next, as shown in FIG. 5, the short pipe 25 is connected to the gas cock connection port 8 of the movable joint 7, and the gas cock 26 is attached to the short pipe 25. Reference numeral 27 is a blindfold plate.

[0020]

The present invention has the above-described structure and operation, and has the following effects.

A. Fix the box at a predetermined position after the gas piping, set the moving joint on it, and project the moving pipe from this moving joint, so that you do not forget the mounting hole of the gas cock during interior work and its position. It does not slip out.

B. When installing the gas cock, pull the movable joint forward to fix the position, and use the short pipe to install the gas cock, so there is no difficulty in installing the gas cock because of the alignment and this position does not match, Workability is significantly improved.
