Description

  The present invention relates to an internal wall structure such as a partition wall provided inside a building so that it can be disassembled and reconstructed, and a construction method for the internal wall structure.

A common construction method for the internal walls of a building is a method in which a steel base material (light iron base material) is assembled vertically and horizontally, and then a face material such as gypsum board is screwed to this foundation assembly. The inner wall can be built at the lowest cost. In this case, the inner wall is finished by applying a finishing material such as wallpaper, cloth, or decorative plate on the face material.

  However, in the case of the internal wall constructed by the above-described construction method, it is difficult to disassemble the component so that the component can be reused even if it is intended to be reused as the internal wall. That is, for example, it is possible to remove screws from the gypsum board used as a face material, disassemble the base assembly, and reuse the steel base material (light iron base material), but this is very laborious. End up. Therefore, even if reuse as a part of the material constituting the wall surface can be assumed, it is not realistic to reuse all members as internal walls.

  In addition, as wall structures that are assumed to be dismantled and reused, those that use partition walls attached later such as partitions are known, but they are very expensive products as wall panels, and transportation costs when transporting them as members Therefore, replacement from the above structure is difficult from the viewpoint of cost.

  The object of the present invention is that it can be constructed in units of members at the time of initial construction, and can also be applied when the ceiling is first constructed, and can be disassembled into the form of a frame assembly at the time of disassembly, and the frame assembly can be used as it is for reconstruction.
