Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a high-rise building having an atrium.

[0002]

2. Description of the Related Art In a conventional building, particularly in a high-rise apartment 1 as shown in FIG. 4, when a living portion 2 is arranged on the outer periphery due to a plan requirement, the central portion is ventilated, daylighted,
Also, from the standpoint of evacuation in an emergency, the number of cases where the blow-through section 3 is used is increasing.

In the case of such a high-rise apartment house 1, a duct floor 6 is formed at the boundary between the low-rise part 4 and the high-rise part 5 as a living area, the whole or most of which is open to the outside. The duct floor 6 is also used as an air introduction portion to the blow-through portion 3, and the wind pressure difference caused by the height difference between the roof opening 3a of the blow-through portion 3 and the duct floor 6 is used to make It aims to achieve ventilation ventilation and smoke exhaust.

[0004]

However, when the duct floor 6 is formed at the boundary between the low-rise portion 4 and the high-rise portion 5 as described above, the overall height of the duct floor 6 is unbalanced due to the floor height of the duct floor 6 and the like. There is a problem that it is easy to invite. It has been difficult to adjust the rigidity of the columns of the duct floor 6 and the high-rise section 5 from the viewpoint of cost. The present invention solves the above conventional problems, and sufficiently secures ventilation ventilation performance of a building such as a high-rise apartment having a stairwell, and is unnecessary for a duct floor, and a high-rise building having a stairwell It is proposed for the purpose of providing a structure.

[0005]

In order to achieve the above-mentioned object, the present invention has a blow-through portion which communicates from a low-rise portion to a roof in a central portion of a building, and each living layer is provided along the circumference of the blow-out portion. In a high-rise building in which an inner corridor is arranged in each layer and a balcony is arranged in each layer along the outer periphery of the building, the floor of each living layer is formed by a void slab, and each hollow part of the void slab is the balcony. From the tip end opening on the side to the tip end opening on the inner corridor side, and it is possible to distribute air or light between the balcony side and the inner corridor side in each layer. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of the present invention.
2 is a conceptual diagram showing the structure of a high-rise building according to this embodiment, FIG.
FIG. 3 is a side view showing the structure of the void slab, and FIG. 3 is an explanatory view showing an operation example according to this embodiment.

In the high-rise apartment house 10 according to the present embodiment, the blow-through portion 1 that communicates from the low-rise portion 11 to the roof in the central portion.
However, unlike the conventional example described above, it is characterized in that the duct floor is not provided at the boundary between the low-rise portion and the high-rise portion.
In each living layer 13, an inner corridor 14 is arranged in each layer along the periphery of the blow-through portion 12, and a balcony 15 is arranged in each layer along the outer periphery of the building.

However, in this embodiment, the living layers 13 are
The floor is formed by a void slab 16 as shown in FIG. Furthermore, each hollow portion 17 of the void slab 16 is
As shown in FIG. 3, the tip end opening 1 on the balcony 15 side
It is arranged so as to communicate from 7a to the front end opening 17b on the side of the inner corridor 14. Therefore, the span from the balcony 15 to the inner corridor 14 is large, and even when a plurality of void slabs 16 are supported continuously by beams, walls, etc., the hollow portions 17 of each void slab 16 are matched and communicate with each other. Shall be installed in.

In this embodiment having the above structure, when wind from a specific direction (for example, wind from the left in FIG. 3) blows outside the building, each tip of the void slab 16 on the balcony 15 side facing this wind. This wind flows into the hollow portion 17 through the opening portion 17a, and the front end opening portion 17 on the inner corridor 14 side is opened.
It reaches b and is distributed to the blow-through section 12. Also,
On the contrary, the air that has flowed into the blow-through portion 12 enters from the tip opening portion 17b on the side of the inner corridor 14 in the direction opposite to the air outlet side, and each tip opening portion of the void slab 16 on the opposite side of the balcony 15 side. Air flows out from 17a to the outside, and a ventilation action is performed.

This is also the case when the direction of the external wind is reversed, and the same action is achieved only by the flow direction of the wind inside the void slab 16 being reversed. As described above, in this embodiment, since air circulation ventilation can be performed between the balcony 15 side and the inner corridor 14 side in each layer, sufficient air circulation ventilation can be achieved without providing a duct floor unlike the conventional example. Can be secured.

Further, on a sunny day or the like, it is possible to introduce the light, which has flowed in from the balcony 15 side, into the blow-out portion 12 through the hollow portion 17 of the void slab 16.

Further, as shown in FIG. 3, the void slab 16
If the air supply hole 18 directed to the living room is formed in the middle of the hollow portion 17, the air supply operation in the living room becomes possible.

Further, as shown in FIG.
If an air conditioner 19 is installed in the hollow slab 16 and the air conditioner 19 is connected to the hollow part 17 of the void slab 16, and if an air supply hole and an exhaust hole toward the living room are formed in the middle of the hollow part 17 as described above, they can be separately It is possible to construct a rational air conditioning system that does not require duct piping.

The present invention is not limited to the above embodiment,
It goes without saying that various modifications are possible without departing from the gist of the present invention.

[0015]

The present invention is constructed as described above,
The following effects can be achieved. (1) Air circulation and ventilation is possible between the balcony side and the inner corridor side in each layer, so sufficient air circulation and ventilation is ensured even without the duct floor as in the conventional example. (2) Balcony side It is also possible to introduce the light flowing in from the inside of the blow-through portion through the hollow portion of the void slab.
