DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for installing a gas meter in a space (pipe shaft) where various pipes such as gas and water are gathered in an apartment house. Also, the present invention relates to a gas meter mounting device used when a gas meter is installed on an outer wall.

[0002]

2. Description of the Related Art FIG. 10 shows an example in which a gas meter is mounted in a pipe shaft. In FIG. 10, reference numeral 100 denotes a pipe shaft, 101 denotes a gas pipe penetrating vertically through the pipe shaft 100, and 102 denotes a gas meter. The gas meter 102 connects an inlet base 103 with an elbow or the like. While connecting to the gas pipe 101 via the inlet connection pipe 104 bent in the three-dimensional direction, the outlet connector 105 is bent in the two-dimensional direction while also connecting the outlet base 105 using an elbow or the like. It is supported by the gas pipe 101 and the outlet pipe 107 by being connected to a vertical outlet pipe 107 that leads to the room through the inside. In the figure, reference numeral 108 denotes a water heater mounted in the pipe shaft 100;
Is a main stopper, 110 is a branch from the outlet pipe 107, and a water heater 10 via a screw cock 111 and a metal flexible pipe 112.
8 is a branch connecting pipe.

FIG. 11 shows a gas meter 202 via a bend pipe 203 and an elbow 204 with respect to an inlet riser 200 and an outlet riser 201 which are set up on the ground in a detached house.
In the example, 205 is an inlet base, 206
Is an outlet cap, 207 is a main stopper, 208 is a test port / purge sleeve, 209 is a header (distributor), and 210 is a metal flexible tube reaching the room.

[0004]

However, the above conventional example has the following disadvantages. a. Since the gas meters 102 and 202 use the bend pipe 203 and the elbow 204 for installation and piping,
Piping work is troublesome, and the number of parts is increased, resulting in high piping costs. b. Gas meter 102 in pipe shaft 100
Is determined by the positions of the gas pipe 101 and the outlet pipe 107, and there is no flexibility in the mounting position. c. The weight of the gas meters 102 and 202 is determined by the gas pipe 101 and the outlet pipe 107, or the inlet riser 200 and the outlet riser 2
01, which is not preferable. An object of the present invention is to propose a gas meter mounting device which does not have the disadvantages described in the above items a to c.

[0005]

The best technical means for achieving the above object are as follows. 1. The supporting member is formed by setting the opening groove of the C-shaped channel long in the horizontal direction downward, the gas inlet is formed downward, and the gas stopper mounting port is formed in the horizontal direction. A mounting plate with screw holes was formed on the upper surface of the rear part via the neck, a gas outlet was formed downward, and a connection port for the outlet cap of the gas meter was formed downward from the horizontal direction. A mounting plate with screw holes is formed via a neck on the upper surface of the rear side of the outlet side member which forms a mouth and a purge port, and a mounting plate for the inlet side member and the outlet side member is provided in an opening groove of the support fitting. When the part is inserted and this mounting plate is engaged with the inner edge of the opening groove, it comes into contact with the outside of the opening groove, and the U-shape in which the necks of the mounting plates of the entrance member and the exit member enter. Forming escape grooves and through holes Against a plate, by screwing into a screw hole provided on the entry side member and the exit-side member before via the opening groove of the through hole and the support bracket provided on both sides of the backing plate,
By narrowing the gap between the abutment plate and the mounting plate, sandwiching both edges of the opening groove, fixing means for fixing the entrance member and the exit member to the support bracket, and a connection port for the entrance member are formed at the rear, A gas stopper having a connection port formed below the inlet base of the gas meter.

[0006] 2. 2. The gas meter mounting device according to claim 1, wherein fixing means for fixing to both side walls of the pipe shaft are provided at both ends of the support fitting. 3. 2. The gas meter mounting device according to claim 1, wherein a support bar for mounting the gas meter on a ground or an outer wall in a detached house is mounted at the center of the support bracket.

[0007] It is more economical to cut the existing C-type channel into a predetermined length and use it. The entry-side member and the exit-side member, including the mounting plate, are integrally formed by die-casting or casting, and the inside and outside of both ends are tapered for connection. For the support bracket, temporarily fix the inlet side member and the outlet side member in the opening groove beforehand, attach the gas meter to this site on site, then tighten the fixing means to perform the final stop, the selection of parts No trouble or loss. Also, if a gas plug (main plug) is attached to the inlet side member in advance,
No more hassle. Note that the number of mounting plates formed on the entrance side member and the exit side member may be one. However,
In this case, the inlet side member and the outlet side member are fixed to one mounting plate by a fixing means such as a screw in accordance with the pitch of the base on the gas meter side.

[0008] When the gas meter is mounted in the pipe shaft, the support bracket is provided with fixing brackets at both ends,
This is taken into the pipe shaft, and the fixing bracket is fixed to each side wall. In this state, the gas meter is attached to the support fitting by connecting the inlet cap to the outlet side of the gas stopper, connecting the outlet cap to the outlet member to determine the position, and by tightening the fixing means. Item 2). When the support bracket is used to support the support bracket, and the gas meter is installed outdoors, the lower end of the support bar is fixed to the ground and the support bracket is installed horizontally, and in this state, the gas meter is connected to the pipe shaft. Attach it in the same way as

The connection between the inlet side member and the gas pipe in the pipe shaft or the connection between the service pipe extending from the ground and the inlet side member is made by a metal flexible pipe. In addition, piping between the header, the gas tap in each room, and the water heater in the pipe shaft is also provided by a metal flexible pipe. However, a metal pipe may be used only between the outlet member and the header.

The lower end of the support bar may be fixed in the ground, but may be fixed to the outer wall of the building by devising its shape.
