Description

TECHNICAL FIELD The present invention relates to a meter box and a method for attaching a meter box door.

Conventionally, a meter box formed in a building skeleton is known. For example, Patent Literature 1 below discloses a meter box that includes a hinged door and a frame body that holds the hinged door so that the hinged door can be opened and closed.

In order to form the meter box of Patent Document 1 on the building frame, first, mortar is placed on the floor surface of the building frame. Then, the lower base material is fixed to the floor surface with anchor bolts through mortar. Also, the upper base material is fixed to the ceiling surface of the building frame with anchor bolts. Then, the frame body is fixed to the lower base material and the upper base material by fasteners. A hinged door is attached to the frame body via a hinge.

JP 2010-95933 A

Here, the dimensions of the rectangular opening between the floor surface and the ceiling surface in the space formed in the building skeleton are likely to cause errors with respect to design values. Therefore, in order to eliminate the difference in vertical dimension between the opening and the frame body having a frame shape, liquid mortar as in Patent Document 1 is placed between the floor surface and the lower base material. . The process of placing mortar on the floor needs to be done by highly skilled craftsmen, and at construction sites where there are only a few highly skilled craftsmen, the process of placing mortar on the floor takes a lot of time. . In addition, since a step of drying the mortar is required, this also increases the time required to attach the frame body and the door. In addition, welding work is performed to configure the frame body, and the work time for performing the welding work further increases the time required to form the meter box. Moreover, a large amount of iron material is required to provide the meter box with a frame body having a frame shape. Therefore, the amount of carbon dioxide discharged for manufacturing the frame body having the frame shape increases. In addition, the amount of carbon dioxide emissions accompanying the transportation of materials for the meter box also increases. In addition, the amount of carbon dioxide emissions for manufacturing and transporting parts in the construction industry is relatively large among all industries, and from the perspective of global environmental protection (for example, carbon neutrality) A reduction in the amount is desired.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a meter box and a meter box door mounting method that does not require a frame body and can shorten the door mounting time.

To achieve the above object, the meter box according to the first aspect includes:
a first upper hinge portion having an upper shaft member extending perpendicularly to the floor surface in the space formed in the building frame;
a first lower hinge portion having a lower shaft member arranged on the axis of the upper shaft member;
a first door to which the first upper hinge portion and the first lower hinge portion are fixed, the first door being opened and closed around the upper shaft member and the lower shaft member;
an upper mounting member to which the first upper hinge portion is fixed, the upper mounting member being fixed to a ceiling surface in the space;
a lower mounting member to which the first lower hinge portion is fixed, the lower mounting member being fixed to the floor;
The upper mounting member is configured separately from the lower mounting member and is spaced upward from the lower mounting member.

Moreover, the mounting method for the meter box according to the second aspect includes:
A method for attaching a meter box door to a space formed in a building skeleton,
a lower mounting step of fixing the lower mounting member to a floor surface in the space;
an upper mounting step of fixing the upper mounting member, which is configured separately from the lower mounting member, to the ceiling surface in the space;
A first door mounting step performed after the lower mounting step and the upper mounting step, wherein a first upper hinge portion fixed to the first door is attached to the upper mounting member, and a first upper hinge portion fixed to the first door is attached to the upper mounting member. and a first door mounting step of mounting the first lower hinge portion to the lower mounting member.

According to the above configuration, since the upper mounting member and the lower mounting member are separately arranged, the space between the upper mounting member and the lower mounting member can be easily adjusted without using a liquid building material such as mortar. You can adjust the distance. By attaching the first upper hinge portion and the first lower hinge portion to the upper attachment member and the lower attachment member, the first door having the first upper hinge portion and the first lower hinge portion can be attached to the building skeleton. can be done. As a result, the frame body is not required, and the mounting time of the first door can be shortened. Moreover, since it is not necessary to provide a frame body having a frame shape, the material can be reduced. As a result, it is possible to reduce the amount of carbon dioxide generated during the manufacture of the meter box, and also reduce the amount of carbon dioxide emissions associated with the transportation of materials for the meter box. As a result, the widespread use of the meter box of the present invention in the construction industry can reduce carbon dioxide emissions in the construction industry.
