Description

  The present invention relates to a self-supporting gas meter mount used when a gas meter is installed in a pipe assembly space (hereinafter referred to as “pipe shaft”) of an apartment house.

  In the case of a detached house, the gas meter is usually installed outdoors. As an example of this, it is common to attach a gas meter to the top of a gas pipe that has started up and entered from the ground by using a vent pipe or the like.

  Further, in an example in which a flexible pipe is used on the outlet side of the meter as in the gas meter support device introduced in Japanese Patent Application Laid-Open Nos. 2008-070160 and 2001-141542, a mounting bracket is used on the wall of the building. A gas meter is installed. However, there are cases where the installation of a gas meter is prohibited on the wall surface in the pipe shaft due to strength problems.

  On the other hand, in the case of an apartment house such as a condominium, a pipe shaft is provided at a position facing the common corridor, and a gas meter is installed in the pipe shaft.

  However, the inside of this pipe shaft is very narrow, and there are not only gas pipes but also water pipes and hot water supply pipes in this narrow space, so the installation space of the gas meter is difficult and installation work is difficult There is. In particular, gas works and water works are carried out separately, and each work is done without a unified rule, so when the work is done later, there are restrictions on the installation position and direction of the meter. There may be a problem that it is difficult to remove.

  In order to solve these problems, Japanese Patent Application Laid-Open No. 09-072770 provides a degree of freedom in the position and direction of the gas meter by directly attaching a fixing bracket that can be rotated in the horizontal direction to the gas pipe. A mounting device is introduced.

  However, in the case of this known example, since the gas meter is directly attached to the gas pipe vertically penetrating the building, a load is applied to the gas pipe, and in the case of the gas meter, a seismic device is incorporated in the inside. If the gas meter is directly attached to the gas pipe, there will be a difference between the shaking of the building and the shaking of the gas pipe, which may cause malfunction.

  For the purpose of solving this problem, as a gas meter base, we combined angle steel and flat steel on the pipe shaft floor, fixed the one assembled in a gate shape by welding, and attached the gas meter to this, but this base is Many apartments are hand-made according to the conditions of the site, and are expensive to manufacture.Therefore, if there are many units like high-rise apartments, the strength calculation of the building will be affected. There is a problem that.

  In addition, in this case, the production cost is low, although such a mountain steel or flat steel is not used, and a pedestal with only one column standing on the base is also used. There is a problem that the gas meter tends to become unstable, an error is generated between the shaking of the building and the shaking of the gas meter, and the strength remains uneasy.

  The subject of this invention is providing the self-supporting mount frame which can install a gas meter, utilizing the space effectively in a narrow pipe shaft.

  Another object of the present invention is to provide a gantry in which the seismic device does not malfunction by making a difference between the shaking of the gas meter and the shaking of the building during an earthquake.

  Furthermore, it is to provide a gantry that is lightweight, inexpensive to manufacture, and excellent in strength.

  Furthermore, it is providing the mount frame which can install a water meter other than a gas meter.

  In order to solve the above-mentioned problem, the invention according to claim 1 is a gas meter stand, wherein a fixing base is attached to a lower end of a square pipe column having a square or rectangular cross section, and a gas meter is mounted on the front side of the upper portion of the column. It is characterized by comprising gas meter fixing means for fixing.

  The invention described in claim 2 is characterized in that in the gas meter stand according to claim 1, a plurality of gas meters can be attached to the support column.

  Further, the invention according to claim 3 is the gas meter stand according to claim 1, wherein the water meter is fixed below a portion of the front side of the support column where the gas meter fixing means is located. The water meter fixing means is provided.

According to the present invention described above, the following effects can be obtained.
1. Since the support column is made of a square pipe, it is hard to bend, and the shaking of the building during an earthquake is accurately transmitted to the gas meter via this support column, so there is no risk of malfunction.
2. Since the support column is composed of a square pipe, it is lightweight, inexpensive to manufacture, and excellent in strength. Therefore, a plurality of gas meters can be attached to one support column.
3. Since the column is composed of one square pipe, a water meter can be attached below the gas meter, and as a result, the vertical space can be effectively used particularly in the pipe shaft.

It is explanatory drawing of the mount based on this invention, a gas meter, and a gas meter mounting bracket. It is an A-A 'line expanded sectional view. It is explanatory drawing of the state which attached the gas meter to the mount frame which concerns on this invention. It is explanatory drawing of the state which attached the gas meter and the water meter to the mount frame which concerns on this invention. It is explanatory drawing which shows the dimension of each part in the mounting condition of the mount frame and gas meter of an Example. It is a comparative graph showing the result of the vibration test done with the mount frame of the Example.

  The gas meter mount according to the present invention can be used not only inside the pipe shaft but also outside the pipe shaft. The gantry is entirely made of metal, and the cost of the square pipe that becomes the support can be reduced by cutting an existing pipe into a predetermined length.

  The gantry uses a anchor bolt or the like on the floor inside the pipe shaft to fix the base so that the column stands vertically.

  FIG. 1 shows a gantry according to the present invention. This gantry 1 is welded to a flat fixing base 2 at the lower end of a column 3 made of a square pipe having a cross-sectional structure shown in FIG. In addition, a tap hole 4 as a gas meter mounting means provided at a position close to the top of the head is provided. In FIG. 3, 5 is a bolt hole through which the anchor bolt 5a provided on the fixing base 2 passes. The top of the column 3 does not necessarily need to be blocked from the viewpoint of performance, but it is preferable to block the top of the column 3 in order to prevent dust and the like from entering the column 3.

  Reference numeral 6 denotes a gas meter. The gas meter 6 is attached to the screw hole 4 of the support column 3 by using a screw 11 via a gas meter mounting unit 7 including outlet and inlet vent pipes 8 and 9 and a mounting bracket 10.

  In the figure, 12 is an inlet cap of the gas meter 6, 13 is an outlet cap, 14 is an inlet union, 15 is an outlet union, and the inlet and outlet caps 12 and 13 of the gas meter 6 are the union 14, 15 respectively.

  FIG. 3 shows an example in which the gas meter 6 is attached to the gantry 1 having the above configuration, and the gantry 1 is fixed to the floor of the pipe shaft by using anchor bolts 5a.

  At this time, the attachment unit 7 of the gas meter 6 may be attached to the support column 3 in advance, or may be attached after the gantry 1 is fixed.

  The gas meter 6 is then attached by connecting unions 14 and 15 to the caps 12 and 13. In FIG. 3, the inlet side gas pipe and the outlet side gas pipe entering the gas meter 6 are omitted.

The mounting specifications of the gas meter 6 described above are shown in Tables 1 and 2 using FIG.

  In this embodiment, one gas meter 6 is attached to the support column 3, but when one pipe shaft is shared by a plurality of units, two or three gas meters 6 are arranged in a column with respect to the support column 3. Alternatively, a horizontal bar may be fixed to the column 3 in a cross shape, and two or three gas meters 6 may be attached to the horizontal bar.

  FIG. 6 shows a case where the gas meter 6 is directly fixed to the vibration device, a 1200 mm-high frame (gate type model) combining conventional angle steel and flat steel, and the gas meter 6 on the frame of the embodiment of the present invention. The result of the vibration test which it attached and performed using the vibration test apparatus (G-3040 by the Kenken Co., Ltd.) is shown.

  From this result, there is almost no difference in the vibration sensor operating gull value between the case where the gas meter is directly attached to the vibration device and the case where the gas meter is attached to the gantry 1 of the present invention. It can be seen that there is a large difference depending on the direction of vibration in the case of a gate-type frame that combines steel and flat steel.

  FIG. 4 corresponds to the third aspect of the invention, and is an example in which the water meter 16 is attached to the lower side of the gas meter 6 using the mounting bracket 17, the screw shaft 18, and the nut 19 in the gantry 1 of the present invention.
