Description

  The present invention relates to a structure of a pipe space provided in a building such as an apartment house.

  In general, in buildings such as apartment buildings, pipe spaces are provided facing common outside corridors and landings for staircases to accommodate piping such as water supply and drainage pipes and gas pipes, and equipment such as water meters and gas meters. doing.

  As this type of pipe space, for example, as disclosed in Patent Document 1, there is a structure in which a recess is formed on the outer periphery of a building and an opening / closing door is attached to the front opening of the recess. . In this case, the substantially concave pipe space peripheral wall is not visible from the outside unless the opening / closing door is opened. Therefore, it is not necessary to place importance on the design, so use a concrete plate such as ALC having excellent fire resistance. Often configured.

JP-A-8-303022

  However, in some apartments, the building outer wall is configured by attaching an outer wall panel in which a metal frame material is attached to the back surface of the exterior material to a frame such as a beam.

  In such a housing complex, if the pipe space peripheral wall is configured by using a concrete plate such as ALC as described above, the mounting structure of the wall material is different between the building outer wall and the pipe space peripheral wall, and the workability of the pipe space is poor. There was a problem of becoming.

  An object of the present invention is to provide a pipe space structure excellent in workability capable of solving the above problems and constructing a pipe space peripheral wall in the same manner as a building outer wall.

  In order to solve the above-mentioned problems, the pipe space structure of a building according to the present invention has a pipe space provided in a recess on the outer periphery of the building, a substantially concave pipe space peripheral wall, and a metal frame material on the back surface of the exterior material. It is characterized by using an outer wall panel similar to the outer wall panel for building outer wall structure to be attached, and having an opening / closing door attached to the front opening thereof.

  Specifically, a mounting plate fixed between the vertical frame members of adjacent outer wall panels is protruded into the pipe space, and the vertical frame member of the open / close door is attached to the mounting plate.

  In addition, a waterproof surface material laid on the walking portion facing the pipe space is raised to constitute the lower frame material of the door.

  Furthermore, it is a pipe space shared by two adjacent dwelling units so as to surround an inner staircase in an apartment house, wherein the pipe space peripheral wall is provided over the entire width of the inner staircase, and the open / close door includes a plurality of vertical doors. A frame member and a plurality of door surface members attached across the vertical frame members are provided.

  Moreover, two door face materials are provided for each house, and the space in the pipe space corresponding to one of the door face materials is used as a multipurpose storage space.

  In the pipe space structure of the present invention, the pipe wall peripheral wall is configured by using the same outer wall panel as the outer wall panel for building outer wall configuration. Therefore, the pipe space peripheral wall can be easily constructed without any change from the building outer wall. It is possible to improve the workability.

  In addition, because the outer wall panel is attached with a metal frame material on the back of the exterior material, the mounting plate for opening and closing the door can be easily inserted into the pipe space while being fixed between the frame materials of the adjacent outer wall panels. For example, compared to a pipe space in which a peripheral wall is configured using ALC or the like, an opening / closing door can be easily constructed.

  Furthermore, the waterproof face material laid on the walking section is set up to form the lower frame material of the door, so that the waterproof property in the pipe space can be improved and the number of parts can be reduced to reduce the cost. be able to.

  Furthermore, the pipe space shared by two dwelling units is provided over the entire width of the inner staircase, and by using a part of the internal space as a multipurpose space, the pipe space can be effectively used. .
