The screws 12 are temporary fixing screws. The temporary fixing screws 12 are screwed into the side walls 101 and 101a before being fixed using the mounting screws 11, and the temporary fixing screws 3 are fixed thereto. The workability is improved by hooking the groove 6 and temporarily fixing it, and then tightening the mounting screw 11.

Reference numeral 13 denotes an entry-side mounting member which is mounted horizontally on the horizontal support 1 by tightening the entry-side screw hole 8 of the backing plate 7 with a screw 18.
The entry-side mounting member 13 includes a horizontal portion 14 and the horizontal portion 14.
The vertical T-shape is formed by forming vertical inlet gas pipe connection ports 15 and 15a behind and a gas plug connection port 16 in the front. Reference numeral 17 denotes a mark provided at the center of the upper surface of the horizontal portion 14 of the entry-side mounting member 13.

Reference numeral 19 denotes an outlet-side mounting member which is horizontally mounted on the horizontal support 1 by tightening the outlet-side screw hole 8a of the backing plate 7 with a screw 20. The member 19 includes a horizontal part 21, outlet gas pipe connection ports 22, 22 a formed vertically in the rear of the horizontal part 21, and a connection base formed with the front part of the horizontal part 21 downward by 90 °. (Bag nut). 25 is a purge / test port, 2
Reference numeral 6 denotes a plug closing the test port 25.

In FIG. 3, reference numeral 27 denotes a gas plug (original plug) connected to the gas plug connection port 16 of the entry-side mounting member 13. The gas flow path of the gas plug 27 is bent 90 ° downward. , The handle 28 for opening and closing the closure faces the front side,
This is a configuration in which an inlet-side mouthpiece connection port 29 to which a connection mouthpiece (bag nut) 30 for connecting to the inlet-side mouthpiece 104a of the gas meter 104 is downwardly formed is formed. When the gas stopper 27 is screwed into the gas stopper connection port 16 of the inlet-side mounting member 13 and attached, the gas stopper 27 may be slightly turned around in the final tightening stage, and the inlet-side mouthpiece connection port 29 may be inclined. . In this case, one more gas stopper 27 is attached.
Since it is impossible to rotate the screw so that it faces directly below, the entry side mounting member 13 is turned over and replaced. In this manner, the gas stopper 27 can be directed downward just by turning the gas stopper 27 a little less than half a turn.
7 can be tightened.

FIGS. 3 and 4 show a state in which the gas meter 104 is mounted. FIG. 3 shows a state in which the inlet-side base 104a of the gas meter 104 is connected to the gas stopper 27 using the inlet-side connecting base 30. FIG. This shows a state in which the outlet side base 104b is connected using the outlet side connection base 24 of the outlet side mounting member 19. FIG. 5 shows the gas meter 104 with the pipe shaft 1
FIG. 6 is a view seen from above, showing a state of being mounted inside 00. FIG.

FIG. 7 is an explanatory view showing a state in which the inlet-side flexible pipe 31 is connected to the inlet-side gas pipe connecting port 15 of the inlet-side mounting member 13. When the connecting port 15 is used in this way, the lower connection is made. The port 15a is closed by the plug 32. In addition, in this embodiment, the inverted T-shaped inlet side attachment member 13 is provided to allow the inlet side flexible pipe 31 to be connected vertically from any direction. Switching is
For example, an L-shaped inlet side attachment member may be formed, and the inlet side flexible tube 31 may be connected from any direction by changing the vertical direction.

In this case, the reinforcing member 34 is arranged below the horizontal support 1. Insufficient strength is compensated for by fixing the tip with a metal fitting 36 and a screw 37. However, when the horizontal supporting metal 1 alone has sufficient strength, the reinforcing member 34 is not required.

FIG. 11 shows an example of a mark provided on the L-shaped entry-side mounting member 13, in which a chevron is formed on the upper surface of the horizontal portion 14 and this vertex may be used as a mark 17, or as shown in FIG. The mark 17 may be formed by forming a protrusion at the center of the horizontal portion 14 as described above.

[0016]

As described above, according to the present invention, since the gas meter can be attached in the pipe shaft by utilizing the lateral wall, it is not necessary to attach the gas meter around the elbow or the bend pipe as in the conventional case. . As a result, the flexible pipe can be used for both the gas inlet and the gas outlet, and the mounting workability of the gas meter is dramatically improved.

The gas meter has a horizontal support bracket,
The position in the horizontal direction can be arbitrarily selected by sliding to the left and right together with the backing plate, or by changing the mounting position of the horizontal support bracket, it can be mounted at the most visible position in a narrow pipe shaft.

Further, in the case of the present invention, since the fixing fitting can be temporarily fixed, the work is very easy. Further, in the case of the present invention, since the mark is provided on the inlet side attachment member, the gas stopper can be properly attached. Further, in the case of the present invention, since the inlet side mounting member can be turned inside out, the gas plug can be securely tightened in the correct direction.
