Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a structure in which a vertical beam is projected on the upper surface of a horizontal frame structure which is connected by a vertical frame structure and divides a building into upper and lower layers, and a floor material is supported on the upper surface of the horizontal beam structure. Study on daylighting and ventilation structure in a building with an underfloor space formed between floor material and horizontal frame.

[0002]

2. Description of the Related Art Conventionally, condominiums such as condominiums have been reinforced by integrally forming girders and girders on the lower surface of a horizontal skeleton consisting of floor slabs that divide the building into layers. The ceiling material is supported from the bottom surface of the floor slab via suspension bolts so as to hide the beam. Further, on the upper surface of the floor slab where the girders and girders are not exposed, a plurality of gables are supported in parallel through a large number of bundles,
A floor material is stretched on the upper surfaces of a plurality of joists that are installed so as to be orthogonal to the upper part of the Daihiki.

[0003]

When the above conventional floor structure is adopted, a dead space that is not effectively used is formed between the floor slab and the ceiling surface, while articles are stored between the floor material and the floor slab. There is a problem that the space for using it cannot be secured. Therefore, by providing a reverse beam on the upper surface of a floor slab that divides a building into upper and lower floors and supporting the floor material on the reverse beam, an underfloor that can be used for storing articles between the floor slab and the floor material. It is possible to form a space.

An object of the present invention is to achieve rational daylighting and ventilation in a building employing the above-mentioned reverse beam structure.

[0005]

In order to achieve the above-mentioned object, the structure of daylighting / ventilation of a building of the present invention has a reverse beam on the upper surface of a horizontal structure which is connected by a vertical structure to divide the structure into upper and lower layers. In a structure in which a floor material is supported on the upper surface of the reverse beam to form an underfloor space between the floor material and the horizontal frame, the floor surface of the overhanging portion protruding from the vertical frame to the outside is a horizontal frame. A column space is formed between the upper edge of the door or window provided on the vertical frame facing the projecting portion and the lower surface of the horizontal frame while being provided at a position higher than the horizontal frame.

[0006]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment in which the present invention is applied to an apartment house. In this apartment house, a plurality of floor slabs 1 as horizontal frames are provided as pillars 2 and outer walls 3 and inner walls as vertical frames. It is composed of a plurality of layers that are divided into upper and lower parts by being connected by 4, and a partition wall 5 divides a plurality of chambers into each layer. Large beams 6 are integrally formed on the upper surface of each floor slab 1 so as to surround the periphery of the chamber, and beam beams 7 having a height and a width smaller than the large beams 6 are integrally formed inside the large beams 6. . On the upper surface of the large beam 6 and the small beam 7, a large pull 8 made of steel and a joist 9 made of wood are used.
Are supported in a grid pattern, and the flooring material 10 is laid on the upper part thereof. Between the concrete slab 1 and the floor material 10,
An underfloor space 11 having a height corresponding to the formation of the large beam 6 and the small beam 7.
The underfloor space 11 is used for various purposes such as storage of articles and air conditioners.

On the south side of the housing complex,
The floor slab 1 extends from the bottom so as to extend outward.
The part 12 is integrally formed. Overhanging portion 1 bent upward
2 end wall 12₁Place the flooring material 10 between the upper end of the
Laying, and the end wall portion 12 ₁Handrail 13 is installed at the upper end of
By kicking, balcony 14 with underfloor space 11
Is formed. The outer wall 3 facing the balcony 14 has a floor
A sash with a high height from the surface to the ceiling can be installed freely
A window 15 is provided.

On the other hand, on the north side surface of the housing complex, a projecting portion 17 is integrally formed on the upper part of the girder 6 so as to form the passage 16. The overhanging portion 17 is composed of a floor portion 17 ₁ and a handrail portion 17 ₂ rising from the outer end thereof, and the floor portion 17 ₁ is provided at a position higher than the floor slab 1 by a step A.

An entrance door 18 is provided on the outer wall 3 facing the passage 16, and a column gap 19 in which glass is fitted is provided between the upper edge of the door 18 and the ceiling surface. A window 20 having a pair of sashes attached to the outer wall 3 so as to be openable and closable.
Between the upper edge of the window 20 and the ceiling surface, there is provided a space 21 having a pair of small sashes that can be opened and closed.

Since the floor surface 17 ₁ of the overhanging portion 17 forming the passage 16 provided on the outside of the outer wall 3 on the north side is higher than the floor slab 1 forming the ceiling surface by the step A,
A space is formed above the outside of the outer wall 3. as a result,
The sunlight for the columns 19 and 21 provided above the door 18 and the window 20 of the outer wall 3 is improved, and the lighting effect is improved. In addition, ventilation is improved by the space, and a sufficient ventilation effect can be obtained by opening the railing 21 provided on the upper portion of the window 20. Moreover, the space 1
By providing 9, 21, it is possible to reduce the feeling of pressure in a narrow entrance or a room.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and various small design changes can be made without departing from the present invention described in the claims. It is possible to do.

For example, in the embodiment, the railing is provided on the outer wall on the aisle side, but it may be provided on the outer wall on the balcony side. Further, the space between the columns is not limited to the fitting glass or the openable / closable window, and may be any louver or the like that is capable of lighting and / or ventilation. Further, the present invention is applicable not only to collective housing but also to other buildings such as office buildings and hotels.

[0014]

As described above, according to the present invention, the height of the floor surface of the projecting portion projecting outward from the outer wall of the building adopting the reverse beam structure is higher than that of the horizontal frame constituting the ceiling surface. Since the height is increased, it is possible to form a space above the outer space between the columns provided on the outer wall of the door or the window. As a result, the sunlight and ventilation to the space between the columns are improved, and it becomes possible to obtain sufficient lighting and ventilation effects.
