Abstract

PURPOSE:To secure a large natural-lighted plane on lower stories by employing steel in only those beams which constitute the outer peripheral skeleton of a structure which is constructed entirely of RC or SRC. CONSTITUTION:Lower-story poles l and upper-story poles 1' are both constructed of SRC and only the lower-story beams of an outer peripheral skeleton face are steel beams 2'. The upper-story beams of a middle skeleton face are beams 2' constructed of RC and beams 2'' constructed of SRC, and the beams of the outer peripheral skeleton face are beams 2'' constructed of SRC. The use of steel beams only for the lower stories reduces the beam depth and increases ceiling height, enabling a large natural-lighted plane to be secured.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the construction of apartment houses and other high-rise buildings and office buildings and other high-rise buildings.

[0002]

2. Description of the Related Art Conventionally, in this type of building frame, if a steel frame structure is used, various problems such as sound insulation, swaying of the building due to wind, solid sound propagation of the steel frame, etc. occur.
Or, it is often made of SRC.

[0003]

When the RC or SRC building structure has a higher floor, the lower floors generally have a larger beam a and a higher floor height h than the upper floors. (Fig. 8
If the natural lighting surface b such as windows on each floor is made constant, the floor heights across all floors are not unified, and the floor heights are changed every several floors, which is economically disadvantageous in construction.

Therefore, if the heights of all floors are made substantially constant,
Compared to the upper floors, the lower floors have a smaller natural lighting surface, the lower floors have poor lighting conditions, and maintenance costs such as heat resource-related costs to supplement them are enormous.
In the figure, C is the ceiling, d is the outer frame, and e is the inner frame beam. The present invention has been proposed in view of the above problems of the prior art, and the purpose thereof is to secure a large natural lighting surface of a lower floor, which is particularly disadvantageous in terms of natural lighting surface, and improve the environment of the living space. The point is to provide the frame structure of the built building.

[0005]

In order to achieve the above-mentioned object, the frame structure of a high-rise building according to the present invention has an RC structure as a whole.
In a structure that is a structure or an SRC structure, only the beams on the lower floors of the outer perimeter frame are configured as a steel frame structure.

[0006]

According to the present invention, as described above, the RC
In a high-rise building of SRC or SRC structure, only the beams on the lower floors of the outer perimeter frame are made of steel frame with a small beam, so the ceiling height of the living room on the lower floors is high, and a large natural lighting surface is secured. The environment of the living space on the first floor will be improved, and maintenance costs for the entire building such as heat resource related costs will be reduced.

[0007]

The present invention will be described below with reference to the illustrated embodiments. 1 and 2 are plan views of an apartment house and an office of RC structure or SRC structure to which the present invention is applied, respectively.
In FIG. 1, A is a living room, B is a pillar, C is a boundary wall, D is a natural lighting surface such as a window, E is a balcony, F is a corridor, and G is a core.

In FIG. 2, H is an office, I is a natural lighting surface such as a window, J is a core, K is a corridor, and L is a pillar. Figure 3
6 to FIG. 6 show an embodiment of the present invention, FIGS. 3 and 4 are plan views of the upper and lower floors of a building, respectively, and FIG. 5 and FIG. In the elevation view of the structure, the lower floor pillar 1 and the upper floor pillar 1'are made of SRC,
Only the lower floor beams of the outer perimeter are composed of steel beams 2, the upper floor beams of the middle floor are RC beam 2'and SRC beam 2 ", and the outer perimeter beams are SRC beam 2". It is composed of

7 and 8 show a living room space to which the present invention is applied. In the drawing, 3 is a large-capacity covering material for the steel beam 2 of the outer perimeter frame of the lower floor, and 4 is a natural lighting surface and is constituted by a window or the like. Yes, 5
Is the ceiling. In the illustrated embodiment, as described above, RC
In the high-rise building of SRC and SRC, only the beam 2 on the lower floor of the outer perimeter frame is made of steel beams, so the beam of the beam 2 becomes smaller, the ceiling height h'becomes higher, and the size of the natural lighting surface is increased. Is secured, the lighting conditions in the lower floors, which have been poor lighting conditions in the past, are improved, the living environment is improved, and the maintenance cost of heat-related resources is reduced especially in the construction of the entire building.

If the beam of the middle structure that may be between the pillar 1 and the dwelling unit is also made of a steel frame, there is a fear that sound may be transmitted between the adjacent dwelling units through the steel beam. Beam is RC
The sound insulation effect is exhibited by being constituted by the beam 2'and the SRC beam 2 ".

[0011]

As described above, according to the present invention, since only the beams on the lower floor of the outer perimeter frame in the RC or SRC structure are entirely made of steel beams, the beams of the same lower level can be obtained. It becomes smaller, the ceiling height of the outer peripheral room on the lower floor becomes higher, and a large natural lighting surface is secured, the living room environment of the lower floor room, which was disadvantageous in terms of lighting, was improved, and maintenance costs such as heat resource related costs were improved. Savings will be made and construction costs will be reduced.
