Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall-building unit for a general residential building, which is mainly produced in a factory and is so-called prefabricated, which is suitable for building a wall or a partition wall for a general residential building, and The present invention relates to a method of constructing and constructing a wall surface of a general house using a wall surface building unit.

[0002]

As is well known, regarding the construction of buildings,
Prefabrication is a prefabricated building where each part of the building is prepared in advance in a factory etc. and each part of the building is brought to the construction site to build and construct the predesigned building. The type of construction method is well known, its demand is spectacular, and many technical improvements have been made,
Has been provided.

On the other hand, the application of wall panel materials such as lightweight cellular concrete panels (ALC panels) and hollow extruded cement panels has become popular as wall panel materials for building interior and exterior wall surfaces in various buildings. The former lightweight cellular concrete panel is produced by subjecting an aerated concrete molded body to an autoclave curing treatment, and the latter hollow extruded cement panel is produced by extrusion molding of cement,
Each of them has excellent properties in terms of lightness, workability, and appropriate strength, and is effectively used in the range of those properties.

However, since the above-mentioned lightweight cellular concrete panel is generally foamy, it is not particularly sufficient as a panel material for constructing exterior wall surfaces in terms of water resistance and weather resistance. Furthermore, the lightweight cellular concrete panel has a uniform rough outer surface,
Also in terms of design decorativeness, the desired purpose could not be sufficiently achieved.

Therefore, conventionally, when the lightweight cellular concrete panel as described above or the hollow extruded cement panel is used as a wall construction material for interior and exterior, the purpose is to improve water resistance, weather resistance and decorative design. Has developed and provided a decorative wall panel formed by laminating a surface mounting means such as a metal panel or a tile piece on the surface of the panel body, and various concrete construction methods using them have been studied.

I have to. Conventionally, when attaching this type of decorative wall panel to the fabric of a building structure, a base material for mounting the decorative wall panel is welded to a C-shaped channel provided on the side of the building structure through a reinforcing bar, or C The angle piece was welded to the mold channel, and the base material for mounting the decorative wall panel was welded and attached to this angle piece.

The above-mentioned welding work for mounting the decorative wall panel is performed at the construction site where the building structure exists, and the welding work itself requires a high level of technology, which lengthens the construction period. In addition to the above, there was a big problem.

Further, according to the above-mentioned decorative wall panel construction method, welding must be carried out while confirming the twist, levelness and verticality of each decorative wall panel by means such as thread tension in the construction process. Therefore, it was extremely difficult to smooth the base material for mounting the decorative wall panel due to the generation of distortion due to the heat of welding.

A further serious problem is that, when a window or the like has to be constructed on a part of the wall surface of the building, the conventional decorative wall panel construction method described above requires more complicated construction work. It has been considered extremely difficult to construct a highly versatile window corresponding to ready-made window sash assemblies of various sizes with respect to appropriately sized base material panel bodies.
