Description

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 board with a reinforcing bar, rust occurs on the reinforcing bar with the passage of time and flows out from the lip of the outer wall panel, and the outer wall may be stained, or the outer wall panel may be damaged by volume expansion of the reinforcing bar due to rust. Reinforcing bars cannot be easily separated, making it difficult to recycle in the future when dismantling buildings.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has been made in consideration of the above-mentioned circumstances. 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]

And a plurality of outer wall panels 1 (see FIG. 3) forming the outer wall of each floor.

Here, a steel column C constituting the steel structure is a square pipe having a rectangular cross section, and a steel beam H is a steel section having an H shape. The steel column C has a length extending from the first floor to the upper floor, and is fixed to a structural foundation (not shown) to form a through column. On the other hand, between adjacent steel columns C, C, steel beams H are interconnected to form floor beams on each floor and hut beams on the top floor. For this reason, a large strength can be obtained with respect to an external force such as an earthquake, and a large space can be secured.

The upper and lower flanges h1, h of the steel beam H
2, a plurality of mounting holes ha are previously formed at set intervals on the indoor side and the outdoor side, respectively, and a lower mounting member 3 and an upper mounting member 4, which will be described later, are fixed via bolts and nuts. Used when doing.

The outer wall panel 1 is made of ordinary Portland cement, siliceous admixture (silica), aggregate (special ceramic lightweight aggregate, organic fiber (cellulose fiber), admixture (methylcellulose)) and kneaded with water. After doing
A hollow, straight extruded cement board obtained by extrusion molding, having excellent fire resistance, water resistance, and freezing resistance, light weight, high strength, and high rigidity.

That is, since the raw material of the outer wall panel 1 itself is a fine clay-like material and has a high density, it has a property that water does not easily penetrate, hardly suffers from freezing damage even in a cold region, and has excellent durability. The compressive strength is as high as 49 MPa (23 MPa for general concrete), and the specific gravity of the base material is 1.4 and the specific gravity of the panel is 0.9, as compared with the specific gravity of the conventional hollow cement board of 1.9. It is lightweight and reduces the weight burden on the steel column C via the steel beam H. By forming a plurality of hollow portions 1a (see FIG. 3), the section modulus is improved, and the panel bending strength (longitudinal direction) is 235MPa, which is more than a multiple of that of a non-hollow shape having the same cross-sectional area. Bending strength. Also, at the time of extrusion molding, a joint pattern can be formed by a deeply engraved design pattern at the same time, for example, a plurality of vertical grooves and horizontal grooves formed at set intervals in the vertical and horizontal directions. It has rich expressive power compared to concrete exterior walls that tend to dry out. Furthermore, the outer wall panel 1 can provide various types of outer wall panels 1 having different sizes and shapes in accordance with the mounting position only by changing the cut dimensions.

Alternatively, one mounting member 8 may be provided between the steel columns C, C, and the outer wall panel 1 may be mounted between the steel column C to which the channel member 82 is fixed and the mounting member 8. The outer wall panel 1 can be similarly attached between the foundation K and the steel beam H on the upper floor.

Also, in the embodiment shown in FIGS. 18 and 19, the case where the outer wall panel 1 is attached using the engaging metal fitting 2 having a P-shaped cross section has been exemplified. A Z-shaped engagement fitting can also be used. In this case, the channel member 82 of the mounting member 8 may have an L-shaped cross section without the lip portion 82a.

In the above-described embodiment, a three-story apartment house has been described as an example. However, a two-story apartment house may be used, the number of floors is not limited, and a detached house may be used.
