JP6935304B2 - Negative pressure adjustment mechanism and high-rise building - Google Patents

Description

The present invention relates to a negative pressure adjusting mechanism applied to a high-rise building having a void (atrium) that opens on the roof and a high-rise building including the negative pressure adjusting mechanism.

Conventionally, in order to improve ventilation and light collection in high-rise buildings such as apartment buildings, office buildings, complex buildings, and hotels, high-rise buildings have voids that extend vertically and open to the roof. (See Patent Document 1).

By the way, in a high-rise building with a relatively high eave height, the pressure inside the void decreases due to the wind passing over the void, and the void may be placed in a negative pressure state. In a high-rise building with a void, when the void is in a negative pressure state, a pressure difference occurs between the void and the living room on each floor provided around the void, which hinders the life and activities of the high-rise building. May occur. For example, the generation of airflow noise (noise) due to the high-speed passage of wind through the insertion passage of the ventilation duct that extends through the living room, the latch bolts and dead bolts of the locks provided on the front door, and their seats (strikes). The high contact pressure with the door causes problems such as opening and closing of the entrance door.

Therefore, the present invention provides a negative pressure adjusting mechanism for adjusting a negative pressure generated in a void of a high-rise building, and also provides a high-rise building including the negative pressure adjusting mechanism.

The present invention relates to a negative pressure adjusting mechanism applied to a high-rise building having a void that opens on the roof and a high-rise building including the negative pressure adjusting mechanism. The negative pressure adjusting mechanism is installed on the roof of the high-rise building and includes a wind receiver that can move along the circumference surrounding the open end of the void.

According to the present invention, when the pressure in the void is lowered by the wind blowing through the roof of the high-rise building and the void is placed in a negative pressure state, it is blocked by the wind receiver and is blocked from the open end of the void. The pressure inside the void can be increased by the wind introduced inside, and the degree of negative pressure can be reduced. The wind receiver can be directed in the direction of the wind by moving it along the circumference around the open end of the void. As a result, it is possible to reduce obstacles to life, activities, etc. in all the living rooms of the high-rise building caused by the negative pressure phenomenon of the void.

The wind receiver is, for example, mounted on the roof of the high-rise building and movably supported along the rail on an annular rail extending on the circumference.

The wind receiver is, for example, a quadrilateral panel having a diameter equal to the diameter of the circumference that surrounds the center of the circumference, or the circumference that surrounds the vertical axis including the center of the circumference. It can consist of a semi-cylindrical panel having a diameter as large as the diameter of.

It is a schematic perspective view of the negative pressure adjustment mechanism which concerns on one Embodiment, and the high-rise building provided with the negative pressure adjustment mechanism. It is a schematic vertical sectional view of the negative pressure adjustment mechanism and a high-rise building shown in FIG. It is a schematic plan view of the roof of the high-rise building shown in FIG. It is a partial cross-sectional view of a negative pressure adjustment mechanism. It is a schematic partial perspective view of the negative pressure adjustment mechanism which concerns on another embodiment.

With reference to FIGS. 1 to 3, the negative pressure adjusting mechanism according to the embodiment of the present invention and the high-rise building provided with the negative pressure adjusting mechanism are indicated by reference numerals 10 and 12, respectively. Reference numerals 14 and 16 indicate the rooftop of the high-rise building 12 and the rising walls provided on the rooftop, respectively.

The high-rise building 12 is composed of an apartment building, an office building, a complex building, a hotel, etc., and includes a void 18 which is a stairwell extending vertically inside the high-rise building 12 and opening to a rooftop 14. The high-rise building 12 and the void 18 shown in the figure each have a rectangular cross-sectional shape, and the high-rise building 12 has four outer wall surfaces 12a and four inner wall surfaces defining the voids 18, respectively. It has four parallel inner wall surfaces 12b. The high-rise building 12 may have a cross-sectional shape other than a rectangle, for example, a cross-sectional shape such as a triangle or a circle.

In the space between the outer wall surface 12a of the high-rise building 12 and the inner wall surface 12b defining the void 18, a large number of living room floors 20 surrounding the void 18, that is, for the purpose of living, office work, medical treatment, work, accommodation, etc. There are multiple floors, each with one or more living rooms that are continuously used for this purpose. For a large number of living room floors 20, these are shown as a whole, not individually, in order to avoid complications in the illustration.

In the void 18, when a relatively strong wind W (FIG. 2) flows over the high-rise building 12, the air in the void 18 is sucked up from the open upper end thereof, and the pressure in the void 18 is lower than the ambient air pressure. It may be in a state of negative pressure. The negative pressure adjusting mechanism 10 applied to the high-rise building 12 is inside the void 18 when the void 18 is placed in a negative pressure state, and when the negative pressure value actually reaches a preset size. It works to increase the pressure of the eggplant and reduce the magnitude of the negative pressure.

The negative pressure adjusting mechanism 10 is provided on the roof 14 of the high-rise building 12. As a result, the negative pressure reducing effect can be exerted on all of the living room floors 20 located below the negative pressure adjusting mechanism 10.

The negative pressure adjusting mechanism 10 includes a wind receiver 22. The wind receiver 22 is installed on the roof 14 of the high-rise building 12, and is movable along the circumference surrounding the open end 18a of the void 18.

The illustrated wind receiver 22 is attached to the roof 14 of the high-rise building 12 and is movably supported along the annular rail 24 extending on the circumference.

The rail 24 has a T-shaped cross-sectional shape, and is composed of a vertical portion 24a and a horizontal portion 24b connected to the vertical portion (FIG. 4). The rail 24 is fixed to the roof 14 at its vertical portion 24a.

On the other hand, the wind receiver 22 has a lower end portion 22a having a C-shaped cross-sectional shape that opens downward. The wind receiver 22 has two sets of rollers 26, 28 including a plurality of (four in the illustrated example) rollers 26, 28 provided at the lower end portion 22a. The two sets of rollers 26 and 28 are arranged so as to be spaced apart from each other in the extension direction (circumferential direction) of the rail 24. The rollers 26 and 28 of each set are arranged inside the lower end portion 22a of the wind receiver 22 and are rotatably supported by the lower end portion 22a. One set of rollers 26 can each rotate about the horizontal axis, and the other set of rollers 28 can each rotate about the vertical axis.

The lower end portion 22a of the wind receiver 22 surrounds the horizontal portion 24b of the rail 24 from above. One set of rollers 26 faces the top of the horizontal portion 24b of the rail 24, and the other set of rollers 28 faces the two sides of the rail 24, respectively.

In the illustrated example, the rail 24 is provided with two grooves 30 that are open to the top thereof and extend in the circumferential direction, and the two rollers 26 are respectively rolled into the two peripheral grooves 30 in the peripheral groove. Movably partially accepted. Further, the rail 24 is provided with two other grooves 32 that are open on both sides thereof and extend in the circumferential direction thereof, and the other two rollers 28 are respectively provided in the two grooves 32 in the peripheral groove. Partially accepted to be rollable. The wind receiver 22 moves along the circumference by rolling the two sets of rollers 26 and 28 with respect to the rail 24.

The illustrated wind receiver 22 is composed of a quarter-spherical panel surrounding the center of the circumference, and has a dome shape as a whole. The quarter-spherical panel has a diameter as large as the diameter of the circumference and has an inner surface 23 that covers half of the open end 18a of the void 18 above it. By moving the wind receiver 22 along the circumference thereof, the wind receiver 22 can be kept in a state of receiving the head wind W on its inner surface 23. When the wind receiver 22 receives the head wind W, the wind receiver 22 blocks a part w of the wind W. The blocked wind w is reflected on the inner surface 23 of the wind receiver 22 and flows into the void 18 through the open end 18a of the void 18 with the quadrilateral inner surface 23 as a guide surface. The wind w flowing inside the void 18 increases the pressure inside the void 18, thereby reducing the degree of negative pressure in the void 18.

As shown in FIG. 5, the wind receiver 22 is a semi-cylindrical shape having a diameter equal to the diameter of the circumference, which surrounds the vertical axis including the center of the circumference (hence, the axis of the void 18). Can consist of a panel of. The semi-cylindrical panel has a cylindrical inner surface 23 that covers the circumference of the open end 18a of the void 18 over half its circumference. The height dimension of the semi-cylindrical panel can be arbitrarily determined. According to this, when the wind receiver 22 receives the head wind W, the wind receiver 22 blocks a part w of the wind W. The blocked wind w is reflected on the inner surface 23 of the wind receiver 22 and flows into the void 18 through the open end 18a of the void 18 with the semi-cylindrical inner surface 23 as a guide surface.

Instead of the illustrated example, the wind receiver 22 can be made of a panel, a block, or the like (not shown) having a flat wind reflecting surface. When the wind receiver 22 having the flat reflecting surface receives the head wind W on the reflecting surface, it blocks a part w thereof. The blocked wind w is reflected by the reflective surface of the wind receiver 22 and flows into the void 18 through the open end 18a of the void 18.

The wind receiver 22 can be rolled on the rail 24 by using, for example, an electric motor (not shown) as a drive source. Further, preferably, the wind direction / anemometer 34 is attached to the wind receiver 22. According to this, the electric motor can be operated based on the indicated value of the wind direction / anemometer 34, and the wind receiver 22 can be placed at a position facing the head wind W.

Further, instead of this example, it is possible that the wind receiver 22 receives the force (wind force) of the wind W and rolls on the rail 24 so as to face the head wind W.

Further, the wind receiver 22 is arranged on the roof 14 and is arranged on a beam member (not shown) extending across the open end 18a of the void 18, and is a support member (not shown) that is rotatable around the axis of the void 18. Can be supported through. As a result, the wind receiver 22 can be made movable along the circumference.

Regarding the wind receivers 22 shown in FIGS. 1 and 5, instead of the illustrated example, they may have a diameter larger than or smaller than the diameter of the rail 24, respectively.

Further, regarding the wind receiver 22 shown in FIG. 1, instead of the example shown in FIG. 5, the lower portion 22a of the wind receiver 22 has an inverted T-shaped cross section (not shown), and the inverted T-shape. An annular space (not shown) having a C-shaped cross-sectional shape that receives the lower portion 22a of the roof and opens upward can be provided on the roof 14. In this example, a set of rollers 26 is rotatably arranged on the bottom surface defining the annular space, and another set of rollers 28 is rotatably arranged on two sides defining the annular space, respectively. Will be done. On the other hand, two peripheral grooves 30 and two peripheral grooves 32 that rotatably receive the two rollers 26 and the two rollers 28 are provided on the bottom surface and the side surface of the inverted T-shaped lower portion 22a, respectively.
