Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aluminum frame structure in a building such as a house.

[0002]

2. Description of the Related Art In recent years, in a private house or a housing complex for a small number of people, steel-framed or reinforced-frame buildings using steel materials for members such as columns and beams have appeared, but wooden buildings are still the mainstream.

As one of such wooden buildings, wooden pillars are erected on the outer wall of the building and main positions inside the building.
There is a structure in which a vertical load is applied by this column.

Alternatively, as one construction method of a wooden building, there is one constructed by a so-called prefabricated construction method established in recent years. This is formed by assembling on-site members such as wooden wall panels and floor panels that have been assembled in advance in a factory or the like, and is configured to receive a vertical load by the wall panels.

[0005]

However, in the conventional wooden building, the fact is that the wooden pillar only functions as a structural material that receives a vertical load, such as a power cord and a water supply / drainage pipe. If there are members that extend vertically in the building, it was necessary to separately secure a space for accommodating those members.

Further, in a wooden building constructed by the prefabricated construction method, inside the building as well as the outer wall portion,
Since it is necessary to arrange a partition panel as a load bearing wall that receives a vertical load, the interior of the building is subdivided by this partition panel and a large space cannot be secured, which reduces the utility value of the space inside the building. there were.

The present invention has been made in view of the above circumstances, has a large space inside a building, and has various functions in addition to merely functioning as a structural material. It is intended to provide a frame structure made of aluminum which is also excellent in strength.

[0008]

In order to achieve such an object, according to the present invention, an aluminum column vertically erected in the vicinity of a central portion of a building and a branch-shaped member joined to a side portion of the aluminum column. And an aluminum beam which is arranged on a horizontal plane corresponding to each floor of the building and whose end extends to the outer wall surface of the building and is joined to the outer wall panel. . Further, in claim 2, the aluminum column and the aluminum beam have a hollow structure each having a hollow portion extending in the longitudinal direction, and the hollow portions are joined in a communicating state, and both hollow portions are connected. In addition, a configuration is adopted in which wiring or piping for passing electricity or fluid for supplying energy or information is arranged.

[0009]

According to the aluminum frame structure of the present invention, the vertical load can be sufficiently received by the aluminum columns standing inside the building, so that it is not necessary to provide a partition panel, etc. A space can be secured. According to the frame structure made of aluminum according to claim 2, the wiring or the pipe arranged from the hollow part of the aluminum column to the hollow part of the aluminum beam is used as a structural material that simply receives a load. Then, by supplying electricity, water supply / drainage, air or the like, it is possible to have a multifunctional function as an energy source or an information source.
