[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foundation of a building capable of shortening a construction period and a construction cost.

[0002]

2. Description of the Related Art Conventionally, as a foundation of a building, a mat slab made of reinforced concrete has been used. In this case, for example, all columns of the building are supported by one mat slab.

[0003]

[Problem to be Solved by the Invention] In the foundation of the above-mentioned building, one mat slab supports all the pillars of the building, so the mat slab becomes large, and the excavation time and formwork amount for the mat slab are large. So,
There was a problem that the construction period was long and the construction cost was high. Therefore, an object of the present invention is to provide a foundation of a building that can shorten the construction period and the construction cost.

[0004]

In order to achieve the above object, the foundation of the building of the present invention comprises a plurality of mat slabs each having a predetermined number of columns and each being arranged at a predetermined distance from each other, And between the mat slabs and between the mat slabs.

[0005]

According to the foundation of the building of the present invention, a plurality of mat slabs having a predetermined number of columns are provided, the mat slabs are arranged at a predetermined distance from each other, and interstitial concrete is poured between the mat slabs. Will be. That is, by providing a predetermined number of columns as a group and providing them on the mat slab and arranging such mat slabs apart from each other, it is not necessary to provide a mat slab between each mat slab. Therefore, the excavation range for the mat slab is reduced, so that the excavation time and the amount of formwork can be reduced.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a building according to an embodiment of the present invention; FIG.

[0007] In the drawing, reference numeral 1 denotes a pillar for supporting a building, which is arranged so as to form, for example, each contact point of a lattice at a predetermined equal pitch. In this embodiment, each pillar 1 is divided into a plurality of pillar groups 1A to 1D, with four pillars 1 adjacent to each other as one group. And the pillar 1 in each pillar group 1A-1D
Are respectively erected on a mat slab 2 of a predetermined thickness made of reinforced concrete.
Are located at each corner of the mat slab 2 having a rectangular shape. As described above, the mat slabs 2 are arranged such that adjacent ones are separated by a predetermined distance. And
Between the mat slabs 2, a concrete slab 3 thinner than the thickness of the mat slab 2 is cast.

In the above, a mat slab forming hole 5 of a predetermined depth for forming a mat slab is excavated in the ground 4 at a position where each mat slab 2 is arranged, and a mold frame (not shown) is formed in the mat slab forming hole 5. And each mat slab forming hole 5,
Excavation of the shallower concrete reinforced concrete section 6 is performed between the five sections. Then, the mat slab 2 including the pillars 1 is formed in the mold of each mat slab forming hole 5, and the concrete slab is poured with the mat slab 2 at the upper surface level (for example, this surface is set as the ground level). Pile concrete 3 in part 6.

According to the foundation of a building having such a configuration, a plurality of mat slabs 2 each having four pillars 1 are provided, and the mat slabs 2 are arranged at a predetermined distance from each other. Soil concrete 3 is to be cast in between. That is, the four pillars 1 are grouped as a group, and these are erected on the mat slab 2, and the mat slabs 2 are arranged apart from each other, so that the mat slab 2 is provided between the mat slabs 2. There is no need to provide them. Therefore, the excavation range for the mat slab 2 is reduced, so that the labor for excavation, the amount of formwork, and the like can be reduced, thereby shortening the construction period and the construction cost.

Further, since the mat slabs 2 and 2 are separated from each other, a relatively shallow space between the concrete slabs 6 can provide a passage for excavating machines, trucks, and the like. Furthermore, since the mat slab reinforcement is adopted as the basic reinforcement, the reinforcement is simplified. In addition, it can be applied to high-rise buildings, and can be applied not only to ground bearing foundations but also to pile foundations.

The pillars of the building need not be limited to those arranged in a lattice as in the above embodiment, and the number of pillars provided on one mat slab is limited to four. These are not necessary, and can of course be changed according to the shape of the building and the like.

[0012]

As described above in detail, according to the foundation of the building of the present invention, a plurality of mat slabs having a predetermined number of columns are provided, the mat slabs are arranged at a predetermined distance from each other, and each mat is provided with a mat. Soil concrete will be cast between the slabs. That is, by providing a predetermined number of columns as a group and providing them on the mat slab and arranging such mat slabs apart from each other, it is not necessary to provide a mat slab between each mat slab. Therefore, the excavation area for mat slabs becomes smaller,
Excavation time and the amount of formwork can be reduced. Thereby, it is possible to shorten the construction period and the construction cost.
