Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the construction of an above-ground building above a basement which can be constructed by building roof panels, wall panels and floor panels into an underground hole formed in the ground. This relates to a building with a basement that is constructed with a basement.

[Prior art and its problems]

In recent years, with the rise in land prices, the number of buildings with basements that can be connected to above-ground buildings and have basements has been increasing in order to make effective use of land.

However, as shown in FIG. 7, in the conventional building with a basement, the roof panel 2, wall panel 3, and floor panel 4 are generally installed in an underground hole formed in the ground within the cloth foundation 1 that supports the above-ground building A. Since a building with a basement is constructed by constructing basement B by constructing basement B and pouring backfill concrete 5 between the above-mentioned cloth foundation 1 and wall panel 3, the above-ground building A and basement B are The propagation of force is blocked by the backfill concrete 5, and the load of the above-ground building A cannot be supported in the basement B, and even when various forces are applied, the above-ground building A and the basement B are not integrated. Therefore, the strength of above-ground building A and basement B must be calculated and designed separately, which is disadvantageous both in terms of strength and economy. There was a problem that uneven settling of the foundation 1 and uneven surfacing of the basement B could occur.

[Means for solving problems]

The present invention erects and fixes a reinforcing beam made of shaped steel at a position near the upper part of the wall panel on the roof panel of the basement, builds and connects the above-ground building on the reinforcing beam, and transfers the load of the above-ground building to the wall panel of the basement. By supporting the above-mentioned building with a basement, it solves the above-mentioned problems of conventional buildings with basements, is rational from both strength and economical points of view, and is characterized by being able to prevent uneven settling of above-ground buildings and uneven surfacing of basements. It has.

〔Example〕

Hereinafter, the present invention will be explained in detail based on examples.

For example, as shown in FIGS. 1 and 2, a desired number of roof panels 2, 2, ..., wall panels 3, 3, ..., and floor panels 4 are installed in an underground hole formed in the ground C. , 4, .
roof panels 2, 2, ... upper wall panels 3, 3, ...
Reinforcement beams 6, 6, .
By integrally constructing and connecting the above-ground building A above, the load of the above-ground building A is transferred to the wall panels 3, 3,... of the basement B via the reinforcing beams 6, 6,... and the roof panels 2, 2,... This invention relates to a building with a basement, characterized in that it is supported by a basement.

The building with a basement shown in FIG. 1 represents an example in which the upper part of the basement B is protruded above the ground to approximately the foundation height of the above-ground building A, and is also used as a cloth foundation for the above-ground building A. In the building with a basement shown in the figure, the top view of the basement B is approximately at the same level as the ground C, and supporting materials 7, 7, etc., such as floor bundles and cloth foundations, are erected on top of reinforcing beams 6, 6,... This shows an example in which an above-ground building A is constructed.

In addition, in the present invention, when reinforcing beams 6, 6, ... are installed and fixed at positions near the top of roof panels 2, 2, ... of wall panels 3, 3, ... of basement B, for example, the third As shown in Figures 6 to 6, reinforcing beams 6a are erected and fixed at corresponding positions 8 on the roof panel 2 so as to correspond to the entire length of the upper end of the wall panel 3 of the basement B. 3,
Reinforcement beam 6 is placed on the roof panel 2 so as to span between 3 and 3.
b can be constructed and fixed.

Further, the roof panel 2, wall panel 3, and floor panel 4 used in the present invention are, for example, L-shaped steel 9a, H-shaped steel 9, as shown in FIGS. 3 to 6.
b, skin plates with a thickness of 4 to 6 mm on both sides of the frame 10 made of the U-shaped steel 9c and other shaped steel 9;
A steel panel formed by stretching other surface materials 11 and 11 and fixing and integrating them by welding, screwing, or other means is most suitable.

In addition, in FIGS. 1 to 6, 12 is covering concrete to be applied to the surface of roof panel 2 of basement B, 13 is backfill concrete to be applied to the surface of wall panel 3, and 14 is waste concrete to be applied to the surface of floor panel 4. , 15 is flooring materials (large pulls, joists, etc.),
16 is a pillar material.

In addition, in the above-mentioned embodiment of the present invention, an example was illustrated in which the basement B was constructed entirely below the above-ground building A, but it is of course possible to construct the basement B in a part of the above-ground building A. .

〔Effect of the invention〕

As described above, the building with a basement according to the present invention has roof panels 2, 2, ... upper wall panels 3 of basement B,
3, ... Reinforcement beam 6 made of shaped steel near the top,
By erecting and fixing the above-ground building A on the reinforcing beams 6, 6,..., the load of the above-ground building A is transferred to the reinforcing beams 6, 6,... and the roof panels 2, 2,... ... through basement B wall panels 3, 3,
..., so that even when various forces are applied, the above-ground building A and the basement B act integrally through the reinforcing beams 6, 6, ..., and the strength is improved compared to the conventional structure. It is economically rational, and
There is no fear that the above-ground building A and the basement B will move separately, and uneven settling of the above-ground building A and uneven levitation of the basement B can be prevented.
