DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a horizontal frame which is connected by a vertical frame and divides a building into upper and lower layers. The present invention relates to a lighting and ventilation structure in a building in which an underfloor space is formed between a floor material and a horizontal frame.

[0002]

2. Description of the Related Art Conventionally, apartment houses and the like are reinforced by integrally forming large beams and small beams on the lower surface of a horizontal frame composed of floor slabs that divide the building into various levels. The ceiling material is supported from below the floor slab via suspension bolts so as to hide the small beams. In addition, on the upper surface of the floor slab where the girders and small beams are not exposed, a plurality of pulleys are supported in parallel through a large number of bundles,
Floor materials are stretched on the upper surfaces of a plurality of joists erected so as to be orthogonal to the upper part of the bridge.

[0003]

By the way, when the above-mentioned conventional floor structure is adopted, a dead space which 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. However, there is a problem that a space for using the information cannot be secured. In view of this, by providing a reverse beam on the upper surface of the floor slab that partitions the building into upper and lower layers and supporting the floor material on the reverse beam, the underfloor that can be used for storing articles between the floor slab and the floor material. It is conceivable to form a space.

[0004] It is an object of the present invention to achieve reasonable lighting and ventilation in a building employing the above inverted beam structure.

[0005]

In order to achieve the above-mentioned object, a lighting / ventilating structure for a building according to the present invention comprises a vertical beam connected to a vertical frame to partition the building into upper and lower layers. In a building in which an underfloor space is formed between the floor material and the horizontal skeleton by supporting the floor material on the upper surface of the inverted beam, the floor surface of the overhanging portion that projects outside the room from the vertical skeleton And a space between the upper edge of the door or window provided on the vertical body facing the overhang and the lower surface of the horizontal body.

[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 a horizontal frame are used as pillars 2 and an outer wall 3 and an inner wall as a vertical frame. A plurality of floors are divided into upper and lower layers by being connected by 4, and a plurality of rooms are partitioned by a partition wall 5 in 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 room, and small beams 7 having a height and width smaller than the large beams 6 are integrally formed inside these large beams 6. . On the upper surfaces of the girder 6 and the girder 7, a girder 8 made of steel and a joist 9 made of wood are provided.
Are supported in the form of a lattice, and a floor material 10 is laid thereon. Between the concrete slab 1 and the floor material 10,
An underfloor space 11 having a height corresponding to the formation of the girder 6 and the girder 7
The underfloor space 11 is used for various purposes such as storage of articles and air conditioning equipment.

[0008] On the south side of the apartment house,
The floor slab 1 is extended from the lower part so as to extend outward.
The part 12 is formed integrally. Overhanging part 1 bent upward
2 end walls 12₁Floor material 10 between the upper end of
Laying and said end wall portion 12 ₁Handrail 13 at the top of
The balcony 14 having the underfloor space 11
Is formed. The outer wall 3 facing the balcony 14 has a floor
A high sash from the surface to the ceiling can be freely opened and closed
Window 15 is provided.

On the other hand, a projecting portion 17 is integrally formed on the upper part of the girder 6 to form a passage 16 on the north side surface of the apartment house. Projecting portion 17 consists of the handrail portion 17 ₂ which rises from the floor portion 17 ₁ and the outer end thereof, said floor portion 17 ₁ is provided on the position higher step A also the floor slab 1.

An entrance door 18 is provided on the outer wall 3 facing the passage 16, and a space 19 into 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 mounted on the outer wall 3 so as to be freely opened and closed.
Is provided between the upper edge of the window 20 and the ceiling surface, and a space 21 to which a pair of small sashes that can be opened and closed is mounted is provided.

[0011] In Thus, since the floor 17 ₁ of the protrusion 17 constituting a passage 16 provided outside the north side of the outer wall 3 is in the position higher step A also the floor slab 1 forming the roof surface,
A space is formed above the outside of the outer wall 3. as a result,
The sunlight to the spaces 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 can be improved by the space, and a sufficient ventilation effect can be obtained by opening the space 21 provided above the window 20. Moreover, the room 1
The provision of 9, 21 can reduce the feeling of oppression in a narrow entrance or 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 appended claims. It is possible to do.

For example, in the embodiment, the spaces are provided on the outer wall on the side of the passage, but it is also possible to provide the spaces on the outer wall on the balcony side. Further, the space between the columns is not limited to a fitted glass or a window that can be opened and closed, and may be a louver or the like as long as it allows lighting and / or ventilation. Furthermore, the present invention is applicable not only to apartment buildings 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 overhanging portion projecting outward from the outer wall of the building employing the inverted beam structure is made larger than that of the horizontal frame constituting the ceiling surface. Since the height is increased, a space can be formed above the outer space between the columns provided above the doors and windows on the outer wall. As a result, the sunshine and ventilation of the spaces are improved, and sufficient lighting and ventilation effects can be obtained.
