DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel house.

[0002]

2. Description of the Related Art Conventionally, there has been known an outer wall panel in which a nut fitting is previously disposed at a predetermined position on the back side and a plurality of hollow portions are formed to penetrate vertically. When an outer wall of a house is formed by using such an outer wall panel, the outer wall panel is fixed to a wall frame set fixed to a foundation or a steel beam. Specifically, the mounting bracket is fixed to the nut bracket embedded in the outer wall panel via bolts, while the joining bracket is fixed to the wall shaft set via bolts, and the mounting bracket fixed to the outer wall panel is fixed to the wall shaft. The outer wall panel is fixed to the wall shaft assembly by mounting the joint member fixed to the wall shaft assembly to the nut fitting of the outer wall panel via a bolt while mounting the outer wall panel on the wall shaft assembly (for example, see Japanese Unexamined Patent Application Publication No. 3288
64 and JP-A-9-328839).

[0003]

However, in order to fix the outer wall panel, a wall shaft assembly is required, and a number of nut fittings must be embedded in one outer wall panel. In addition, while a plurality of mounting brackets are fixed to one outer wall panel using nut fittings, a plurality of joining brackets must be fixed to one wall shaft assembly, which increases costs and reduces work costs. There was a problem that much time was required.

[0004] Further, in order to improve the bending strength of the above-mentioned outer wall panel, it is necessary to arrange a steel material in a hollow portion of the outer wall panel or on a back surface thereof to reinforce the outer wall panel. As a result, the above-mentioned wall frame and steel work on the steel beam together with the outer wall panel, and the weight load on the steel beam increases, and the degree of freedom in design is impaired.

It is known that a solid ALC plate is used for an outer wall panel, but the specific gravity of the ALC plate is as small as 0.6 and light, but the bending strength is small. For this reason, when the ALC plate is used for the outer wall panel, an ALC plate with a reinforcing bar in which a reinforcing bar is disposed is usually employed. However, in the ALC plate with a reinforcing bar, rust is generated on the reinforcing bar with the passage of time, and flows out of the opening of the outer wall panel, and the outer wall may be stained, or the outer wall panel may be damaged due to volume expansion of the reinforcing bar due to the rust.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an outer wall panel made of a hollow, straight cement-extruded plate is used to form a foundation or a steel structure without using a reinforcing member such as a wall frame. The present invention provides a steel-framed house capable of forming an outer wall of each floor by being fixedly supported on a steel beam.

[0007]

The main structural part is constituted by a plurality of outer wall panels made of a cement extruded plate of the streaks, and the lower end of each outer wall panel is supported by a foundation or a steel beam on the lower floor except for a portion corresponding to an opening such as a window. In addition, a predetermined position on the back side of each outer wall panel is fixed to the foundation or the lower frame steel beam and the upper floor steel beam, respectively, to form the outer wall of each floor.

According to the present invention, an outer wall panel made of a hollow unstrengthened cement extruded plate having high strength and high rigidity, despite being excellent in fire resistance, water resistance and freezing resistance and being lightweight, is used. Or to be supported by steel beams on the lower floor, and installed sequentially between the foundation and the steel beams on the upper floor or between the steel beams on the lower floor and the steel beams on the upper floor without using reinforcing members such as wall frames. Can be.

As a result, the number of parts is reduced, the outer wall panel can be mounted in a short time, and the outer wall of each floor can be formed with reduced cost.
