Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a ventilation structure for a high-rise building having an atrium.

(Prior Art) In a conventional building, especially a high-rise apartment building 1 as shown in FIGS. 3 and 4, when the living area 2 is placed on the outer periphery due to floor plan requirements, the central area is not suitable for ventilation, There is an example where the atrium part 3 is used from the viewpoint of daylighting and evacuation in case of an emergency.

In such a conventional example, as shown in FIG. 4, a corridor 4 is arranged around the atrium 3, and each living area 2, an elevator (not shown), various equipment spaces, etc. are arranged around the outer periphery of the corridor 4, and the outer periphery of the living area 2 is A balcony 5 facing the outside is provided.

However, in the case of such high-rise apartment complex 1, the first
The entire floor is open to the outside, with pillars only, and there are many examples where two or more floors are used as living quarters.

This uses the pilotage 6 as an air introduction part to the atrium 3, and utilizes the wind pressure difference caused by the height difference between the vicinity of the roof opening 3a of the atrium 3 and the above-ground pilotage 6. This is intended to provide ventilation within the building.

(Problems to be Solved by the Invention) However, according to the experimental results etc. by the applicant of the present application, with such a conventional configuration, the wind pressure difference caused by the above-mentioned height difference is often not sufficiently expressed. It was confirmed that there is a problem in that it is difficult to ensure sufficient ventilation performance.

The present invention was proposed for the purpose of solving such conventional problems and improving the ventilation performance of buildings such as high-rise apartment buildings having open ceilings.

(Means for Solving the Problems) In order to achieve the above object, the ventilation structure of a high-rise building according to the present invention has an atrium in the center that communicates from the lower part to the roof, and the outer surface of the lower part In a high-rise building in which an opening that communicates with the atrium from the outside is provided on at least one side of the atrium, a wind shielding member that rises by a predetermined distance is provided near the periphery of the rooftop opening of the atrium. This is a characteristic feature.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

1 and 2 show an embodiment of the present invention,
The high-rise apartment complex 10 according to the present embodiment has an atrium 11 in the center that communicates from the lowest floor to the roof, a corridor 12 is arranged around the atrium, and living areas each having a predetermined number of units are arranged around the outer periphery of the corridor 12. 13 are placed,
Further, an external balcony 14 is provided on the outer periphery of the residential area 13 facing the outside for each residential unit.

Further, as shown in FIG. 1, the first layer portion is a pillar 15 that is entirely open to the outside and consists of only pillars.

Therefore, in this embodiment, a wind shielding member 17 is disposed in a closed manner around the rooftop opening 16 of the atrium 11, rising by a predetermined distance.

The vertical dimension of the wind shielding member 17 is, for example, about 1.5 m in the case of a 25-story high-rise residential building.

Further, in this embodiment, an opening 18 communicating with the atrium 11 from the outside is formed in a specific layer of the lower layer, as shown in FIGS. 1 and 2.

The openings 18 are provided on each of the four sides of the building, as shown in FIG. 2, so that wind can enter from any direction.

In this embodiment having such a configuration, the first
As shown in the figure, for example, when the wind is blowing from the left direction in the figure, there is generally a pressure difference between the rooftop area and the low-rise area that corresponds to the high-speed pressure q due to the altitude difference based on the height L of the apartment complex 1. occurs, and negative pressure is generated within the blow-through section 11.

Further, due to the action of the general wind member 17, the wind on the rooftop is redirected upward at a position directly above the rooftop opening 16, so that an upward airflow from inside the atrium 11 toward the sky is forced near the rooftop opening 16. occurs.

Therefore, due to the effect of the negative pressure and the rising air current, ventilation within the atrium 11 is effectively achieved.

Further, in this embodiment, as shown in FIG. 2, most of the wind that enters from the windward opening 18 (upper part in FIG. 2) is blocked by the internal wall surface facing the open-air part 11, and , due to the above-mentioned negative pressure and rising airflow, the air flows inside the atrium 11 toward the rooftop, and furthermore, both openings 1 in the left and right direction in FIG.
6, a predetermined amount of air is introduced by the action of the negative pressure in the atrium 11 and the upward air current, and the flow rate of air in the upward direction in the atrium 11 is significantly increased compared to the conventional case. , ventilation performance is greatly improved.

Therefore, the living environment of each corridor 12 and each resident section in the middle class section facing the atrium 11 is improved.

In addition, the negative pressure inside the atrium 11 is reduced by the flow of a large amount of air, which eliminates the difficulty of opening and closing the doors of each dwelling unit and of drawing air into the room.

Incidentally, the upright dimensions of the wind shielding member can be appropriately set to optimal dimensions according to conditions such as the height of the building and the size of the atrium 11.

Further, if the openings 18 are provided on four sides as in this embodiment, it is most efficient as it can deal with the wind in any direction, but the present invention is not limited to this, and the It goes without saying that various modifications are possible without departing from the gist of the present invention, such as just providing it on the surface.

(Effects of the Invention) The present invention is configured as described above, and has an atrium in the center that communicates from the lower part to the rooftop, and at least one outer surface of the lower part that communicates with the atrium from the outside. In high-rise buildings with openings, by installing a wind shielding member that rises by a predetermined distance near the roof opening of the atrium, it is possible to reduce the height difference between the roof of the building and the ground area. In addition to the negative pressure used within the atrium, the upward airflow generated by the action of the wind shielding member improves the ventilation performance within the atrium, thereby significantly improving the living environment in the area facing the atrium. This is extremely useful.
