DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a building, and more particularly to a structure capable of securing a high ceiling height even at a low floor height.

[0002]

2. Description of the Related Art When a building is provided in an area with height restrictions, it is necessary to reduce the height of each floor in order to increase the number of floors within the restrictions. For example, if the height limit is 10
When planning a three-story building in the first-class residential area designated as m, the floor height of each floor is limited to about 3.3 m.

[0003]

However, if the floor height of the building is simply reduced, the ceiling height may be reduced as it is, which may impair comfort and habitability. If the ceiling is enlarged or the double ceiling is omitted to make the ceiling straight, it may be difficult to install and store equipment related to equipment and piping and wiring.

[0004] In view of the above, it is an object of the present invention to provide a structure of a building capable of securing a large effective ceiling height even at a low floor height.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an elevation view of a skeleton of a building according to the structure of this embodiment, and FIG. 2 is a beam plan. This building is a three-story reinforced concrete school with two sides of corridor 1 located in the center, each with a living room 2 where a plurality of classrooms are placed. However, this building is to be built in a first-class residential area with a height limit of 10 m, and therefore, as shown in FIG.
50mm, the height of the third floor is 3,350mm, and the floor level of the first floor is GL + 100mm, so that the total height is 9,950.
mm within the limits.

[0009] The living room 2 of this building is constituted by a ramen frame 3, and the corridor 1 is constituted by a beamless slab 4. The ramen frame 3 includes an outer pillar 5 provided at a position on the outer periphery of the living room, an outer girder 6 in the girder direction provided between the outer pillars 5, an inner pillar 7 provided on both sides of the corridor 1. A girder beam 8 in the girder direction installed between the columns 7, a large beam 9 in the span direction installed between the outer column 5 and the inner column 7, and a small beam 10 installed between the outer beam 6 and the large beam 8. It is configured as a main member. The small beams 10 can be omitted, or may be further increased if necessary. Also, it is of course possible to provide an earthquake-resistant wall at a key point as needed.

The beamless slab 4 is provided between the ramen frames 3 on both sides of the corridor 1 and forms part of the floor and roof of the corridor 1. Since the corridor 1 is configured as the beamless slab 4 as described above, the structure of the present embodiment has a configuration in which the large beams 9 and the small beams 10 in the span direction are omitted between the inner columns 7. Reference numeral 11 denotes a slab of the living room 2 on each floor, which is supported by the outer girders 6, girders 8, 9, and the girder 10.
Reference numeral 12 is a roof slab, 13 is a foundation beam, 14 is a pile, 15
Is a duct shaft provided as needed.

In the building of the present embodiment, the girder 8 in the girder direction (located on both sides of the corridor 1) erected between the inner columns 7 has a normal cross section, but the outer girder 6 is a roof beam. Except for, it is a wall girder (wall beam), the upper half of which is a waist wall, and the lower half of which is a vertical wall, which also serves as an outer wall. Further, the beam structure of the large beam 9 and the small beam 10 in the span direction is equivalent, and a flat beam whose dimension is substantially equal to the width dimension is employed.

Further, in this building, the ceiling surface of the classroom provided in the living room 2 has a direct ceiling finish, and a double ceiling is not provided as usual, but an appropriate finish is applied to the lower surface of the slab 11 on the upper floor. (For example, fluttering of stones). In addition, the floor surface of the living room 2 has a straight floor finish in which an appropriate floor finish material (for example, flooring or the like) is directly attached to the upper surface of the slab 11. With such straight ceiling finish and straight floor finish, the slab thickness and ceiling finish, the dimensions required for the floor finish need be less than 200 mm, and therefore the floor height is set to be sufficiently small as 3,250 mm as described above. Also, the effective ceiling height in the portion excluding the positions of the girder 9 and the girder 10 can be secured as large as 3,000 mm or more, and a sufficiently comfortable environment as a classroom can be obtained.

[0013] Even if the living room 2 is finished with a straight ceiling, various equipment can be installed without any trouble by providing a double ceiling in the corridor 1 and using the space behind the ceiling. For example, when air conditioning is performed on the living room 2, an air conditioner such as a fan coil unit is installed in the space above the ceiling of the corridor 1 and a duct penetrating the girders 8 is provided to supply air into the living room 2. Just do it. In this case, since the corridor 1 is constituted by the beamless slab 4 and the beams crossing the corridor 1 are omitted, the air conditioner and other equipment can be installed in the space above the ceiling of the corridor 1 without any trouble. This can be effectively used as a space for installing a main flow line such as a duct, a pipe, or a cable.

As described above, the building according to the present embodiment has a beamless slab 4 between the frames 3 constituting the living room 2.
It is a matter of course that the structural stability and reliability can be sufficiently ensured as a whole, and the living room 2 (the classroom in the present embodiment) has an effective ceiling by finishing the ceiling directly. By providing a double ceiling in the corridor 1 while securing a large height, it is possible to install equipment and devices there without hindrance, and therefore, without sacrificing livability and comfort, and The floor height of the building can be made sufficiently small without difficulty in installation and installation, and it is suitable as a structure of a building to be built in an area with height restrictions.

In particular, in the building according to the present embodiment, the large beams 9 and the small beams 10 are flat beams having a small beam structure, so that the dimensions under these beams can be ensured to be larger than those of a beam having a normal cross section. .

Further, in the building of the present embodiment, since the outer girders 6 employ a wall girder which also serves as an outer wall, the beams do not protrude into the living room portion 2 as in the case of a beam having a normal cross section. Further, as shown in the drawing, the wall girder as the outer peripheral girder 6 is eccentrically provided inside the outer peripheral column 5, so that the column shape of the outer peripheral column 5 does not protrude into the living room 2.

In the above embodiment, a building having a low floor height and a high ceiling height is required to be provided in a first-class residential area.
Although the present invention is applied to a multi-storey school, it goes without saying that the structure of the present invention is not limited to this and can be widely applied to buildings of any use, scale, and form.

[0018]

According to the first aspect of the present invention, as a structure of a building in which living rooms are arranged on both sides of a corridor, a ramen frame is formed in the living room, and a corridor is formed between the ramen frames. Because it has a beamless slab
It is possible to install a double ceiling in the corridor and install equipment and facilities in the corridor without hindrance while securing a large effective ceiling height by finishing the living room part with a direct ceiling finish. Without sacrificing the facilities and making it difficult to install and store various facilities, it is possible to make the floor height of the building sufficiently small. It is suitable as a structure.

According to the second aspect of the present invention, the large beam in the span direction is a flat beam having the same dimension as the width dimension, so that the dimension under the beam can be ensured to be larger than that of a beam having a normal cross section.

According to the third aspect of the present invention, since the outer girders are wall girders, the beam shape does not protrude into the living room.
