Inasmuch as the lower layer void part of the lower layer part 12 is formed with the earthquake resisting wall 16, so that its earthquake resistance strength as well as its structural strength can be improved, a non-column space of the residence 22 can be realized, as a result, the degree of freedom of the design of a room arrangement can be advanced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-rise building such as an apartment building or an office building having a parking lot installed in the building.

[0002]

2. Description of the Related Art Heretofore, a center-core type building having a void portion in the center of a high-rise building has been known. In the structure of a building having such a void portion, a pillar is provided at a place allocated in a grid shape, and then a void portion is provided so that a central portion of the building has an atrium structure extending over upper and lower floors. In addition, a residential building in which dwelling units, offices, and the like enter is provided so as to surround the central void portion.

[0003]

However, in the case of a conventional high-rise building having a void portion, the spacing between the standing pillars is only about 6 to 7 m, so that the arrangement of dwelling units in a residential building around the void portion is required. Is subject to restrictions.

[0004] In addition, since the spacing between the pillars is small, it is practically impossible to change the layout of the future and the arrangement of the dwelling units. Particularly, when the building is a high-rise apartment building, the schedule from planning to completion Is two to three years long, making it impossible to change the floor plan or the like in response to changes in the market.

[0005] Further, conventionally, as a place for installing a parking lot, it has been often installed outside or underground of a building, but it is not possible to effectively use land, which leads to an increase in cost, a longer construction period, and the like. Has problems.

The present invention has been made in view of such problems of the prior art, and has a high degree of freedom in arranging dwelling units and rooms in a residential building in a high-rise building having a void portion in the center of the building. The purpose of the present invention is to provide a high-rise building that can flexibly cope with future changes in floor plans. Also,
When installing a parking lot in a building, the construction period is short,
An object is to provide a high-rise building capable of reducing building costs.

[0007]

According to the present invention, there is provided a center-core type high-rise building having a void portion formed in the center and a living building provided around the void portion. And a seismic wall is erected in the center of the lower part to form a lower part void, and a multi-story parking lot is installed in the lower part void.

[0008] Further, the present invention is characterized in that the upper layer portion is formed by a rigid frame structure, and an upper layer void portion continuous with the lower layer void portion is provided in a central portion.

Further, the space between the lower void portion and the upper void portion is defined by a concrete slab.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a front view of a high-rise building according to an embodiment of the present invention. The present embodiment is a high-rise building 10 having a floor on each floor that is stacked in a multilayer shape.
It is a center-core type building in the center of which is formed a void surrounded by a residential building. Further, the lower layer portion 12 and the upper layer portion 14 having the boundary of the line XX have different structures as described later.

FIG. 2 is a cross-sectional view taken along the line II-II of FIG. As shown in the figure, a reinforced concrete earthquake-resistant wall 16 having sufficient strength against an earthquake is constructed on a foundation (not shown) in the lower layer portion 12 so as to form a central square in plan view. The space surrounded by the standing earthquake-resistant wall 16 is a lower void portion 18. On the other hand, a stud 19 is erected between the peripheral earthquake-resistant walls 16a which do not form the lower void portion 18.

A mechanical multi-story parking lot 20 is installed inside the lower void portion 18 by utilizing a closed space. The earthquake-resistant wall 16 has not only earthquake-resistant strength against earthquakes but also fire-proofing against fires.
And the surrounding residential building 22 is completely partitioned, and has a function of preventing the spread of fire in the event of a mutual fire. Although not shown, dwelling units and rooms are arranged in the living ridge 22 around the lower void portion 18.

FIG. 3 is a cross-sectional view taken along the line III-III of FIG. Upper section 14
The difference is that the lower part 12 is constructed by the earthquake-resistant wall 16, whereas the pillars 24 constituting the ramen frame together with the beams not shown are erected in place. Since the beam and the column 24 have a rigid structure with a rigid frame, each column 24
It has the feature that the space L between them can be widened, so that the frontage can be widened, and in the case of, for example, an apartment or an office building, the degree of freedom in changing the floor plan is increased. In addition, a space between the upper surface of the lower void portion 18 and the lower surface of the upper void portion 26 is partitioned by a concrete slab (not shown), and the lower void portion 18 and the upper void portion 26 are completely separated.

The upper void portion 26 is different from the lower void portion 18 described above, and serves as a ventilating space for lighting and ventilating the living room. Although not shown, an elevator connecting the floors of the lower layer portion 12 and the upper layer portion 14 is provided along the lower layer void portion 18 and the upper layer void portion 26, or is provided in the residential building 22. Further, an outer wall material 28 is attached around the living building 22.

As described above, according to the high-rise building of the present embodiment, since the lower void portion 18 of the lower portion 12 is formed by the earthquake-resistant wall 16, the earthquake-resistant strength can be improved and the conventional structure can be provided. Since the structural strength is improved as compared with the case where the void portion is constructed by the pillar, a pillar-free space can be realized in the living building 22. As a result, the frontage can be widened without being restricted by the pillars, the degree of freedom of the floor plan design of the living building 22 can be improved, and it is possible to flexibly respond to design changes and the like. Therefore, especially in the case of a high-rise building requiring a long period of time for construction, it is possible to change the floor plan or the like according to changes in the market even after the start of construction. Also,
The degree of freedom for remodeling after construction is high.

Further, since a parking lot is provided in the lower void portion 18 in the building, there is no need to provide a parking lot outside the building, so that the construction period required for the building can be shortened and land can be saved. Can be used effectively.

In addition, since the upper layer 14 of the building is formed by a ramen frame, a rigid structure can be adopted as compared with the conventional structure using columns, and similarly to the lower section 12, the restriction by columns is used. And the degree of freedom for layout design and post-construction remodeling is high.

In this embodiment, the case where the present invention is applied to a high-rise building has been described, but it is needless to say that the present invention can be applied to a middle-rise building of about 10 floors.

[0020]

As described in detail above, according to the present invention, a seismic wall is erected in the center of the lower part to form a lower part void, and a multi-story parking lot is installed in the lower part void. Therefore, it is not necessary to set up a parking lot outside the building, and the land can be effectively used. Further, since the lower void portion and the lower layer portion are formed of the earthquake-resistant wall, a column-free space can be realized, and the degree of freedom of the floor plan design of the living building is improved. Furthermore, since the upper part has a structure of a ramen frame, the span between the pillars can be widened, and a living space with a wide frontage can be realized like the lower part.
