BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spacer for preventing deformation of a meter box frame, which is used for installing a meter box.

[0002]

BACKGROUND ART meter box is intended to be used to secure a space when setting <br/> place the water meter or the like during the earth, generally, and the meter box frame body, the meter box frame And a lid that closes the upper surface of the body so that it can be opened and closed. Then, when installing the meter box, it is usual that the upper surface of the lid is made to coincide with the surrounding ground surface, and the entire meter box frame is buried in the ground.

On the other hand, recently, as a material for a meter box, a transition from conventional cast iron to a synthetic resin, particularly a transition to FRP reinforced with glass fiber, etc. has been progressing. Compared with cast iron, the meter box made of synthetic resin has advantages such as being light and easy to carry and not rusting, but has a disadvantage that it is easily deformed when an external force is applied due to its low rigidity.

[0004] Therefore, between the edge of the meter box frame and the lid, by a slight providing "gap", the meter box frame slightly on the side earth pressure during meter box placed <br/> Even if it is deformed, the opening and closing of the lid is not hindered.

However, in the actual installation of the meter box, since the surrounding ground is rolled by a tamper or the like, the meter box frame is greatly deformed by the side earth pressure at the time of the rolling, and the above-mentioned "gap" is formed. May disappear, and a situation may occur in which the original function of the “gap” cannot be exhibited. Furthermore, when the meter box frame is severely deformed by the side earth pressure during the rolling work, not only the "gap" disappears, but also the edge of the lid floats up, and the lid cannot be closed in some cases.

As a countermeasure against this, for example, Japanese Utility Model Laid-Open No. 1-61
As disclosed in Japanese Unexamined Patent Publication No. 620, it is possible to provide a reinforcing member which is installed in the width direction in the housing main body and is slidable and removable in the length direction of the housing main body near the upper opening of the water main body. Conceivable.

However, the structure disclosed in the above publication requires a special support mechanism for holding the reinforcing member in the case main body, and cannot be used in a conventional water meter case which has already been commercialized.

[0008]

[Problems to be solved by the present invention] The problem to be solved by the present invention is that deformation of the meter box frame during ground compaction can be effectively prevented, and even conventional meter boxes already on the market are available. It is to obtain a usable spacer for a meter box.

[0009]

In order to solve the above problems SUMMARY OF THE INVENTION, meter box for a spacer of the present invention, the main Tabokkusu frame the edge of the openable provided with a lid on the upper surface of the meter box frame A spacer for a meter box that is detachably attached to a gap between the top plate and the bottom plate that sandwiches the lid from above and below, and at least one of the top plate and the bottom plate has an edge of the lid and a meter. A special feature is the formation of an intermediate plate interposed between the box frame and the gap.
