Abstract

PURPOSE: To shade insolation without harming the appearance of a building, requiring the separate installation of such a device as a blind or the like or obstructing even the prospect from a window. CONSTITUTION: In a building skeletom being composed of a column 1 and each beam 2, this column 1 and two beams 2 are installed in the outside of an outer wall 3 as separating from it. A light shelf 6 is installed outward in a window 5 as being situated beneath the beam 2 and separated from the outer wall 3 in an interspace to be formed between this outer wall 3 and those of column 1, beam 2. Then, each grating 9 is laid down on the level of a floor 8 lying between the beam 2 and the outer wall 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar radiation shielding structure for a building frame.

[0002]

2. Description of the Related Art In a high-rise building such as a building, as a solar radiation shielding means for shielding sunlight incident from a window, conventionally, for example, an eave is provided on the outer side of the outer wall by being placed above the window or a blind is provided at the window opening. Are attached.

[0003]

In the method of providing the eaves on the outer wall by locating the eaves at the upper part of the window, the eaves cannot be largely projected outward from the outer wall, the shielding effect is low, and the eaves are not present. It often impairs the appearance of the building. The method of installing a blind requires a separate blind for each window and raises and lowers depending on the angle of sunlight, which is troublesome and hinders the view.

The object of the present invention is to eliminate the disadvantages of the above-mentioned conventional example, do not impair the appearance of the building, do not need to separately install a device such as a blind, do not disturb the view from the window, and effectively shield the sunlight. It is to provide a solar radiation shielding structure that can be performed.

[0005]

In order to achieve the above-mentioned object, the present invention is, firstly, in a building skeleton constituted by columns and beams, columns and beams are provided outside the outer wall and spaced apart from the outer wall, and The gist of the present invention is to provide a light shelf outside the window in a space formed between the pillar and the beam, below the beam and spaced from the outer wall.

Secondly, in a building frame composed of pillars and beams, pillars and beams are provided outside the outer wall so as to be spaced apart from the outer wall, and the space is formed between the outer wall and the pillars and beams. A light shelf is provided on the outside of the window so as to be located at a distance from the outer wall, and a grating is laid on the floor level between the beam and the outer wall.

[0007]

According to the first aspect of the present invention, the pillar and the beam are provided outside the outer wall so as to be separated from the outer wall, and the pillar and the beam are positioned below the beam in the space formed between the outer wall and the pillar and the beam. And, by providing a light shelf outside the window, separated from the outer wall,
Since the solar radiation is shielded by the light shelf outside the window, the shielding efficiency is improved. In addition, the light reflected by the light shelf enters the room and the lighting efficiency is improved.

According to the second aspect of the present invention, in addition to the above-described action, by arranging the grating at the floor level between the beam and the outer wall, indirect light can be dropped near the window. This grating can also be used as a passage for maintenance and disaster prevention.

[0009]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a vertical cross-sectional side view showing an embodiment of the solar radiation shielding structure of the present invention, which will be described as an example when it is applied to a high-rise building such as a building.

In the figure, 1 is a column constituting a building frame, 2 is a beam, and as a basic structure of the building, an outer wall 3 is provided inside the columns 1 and 2 and is spaced apart from the column 2 and the outer wall 3 A space 4 is formed between the pillar 1 and the beam 2. Reference numeral 5 in the drawing denotes a window formed as an opening in the outer wall 3.

In the building frame having such a structure, a light shelf 6 is provided below the beam 2 at a position separated from the beam 2 and outside the window 5 so as to be separated from the outer wall 3. The light shelf 6 is made of, for example, a honeycomb panel made of aluminum.

As a result, the light shelf 6 is arranged in the space 4 in a suspended state.
As an arrangement position, for example, the light shelf 6 on the day of the winter solstice
The installation height is determined so that the reflected light of the sunlight that hits the inner edge of the upper surface of the room hits the ceiling inside the room 7. Also, on the day of the summer solstice and the day of the winter solstice, the outer edge of the light shelf 6 is The projection length of the outer end of the light shelf 6 from the beam 2 was determined so as to block solar radiation to the inside of the beam 7, and the light shelf 6 was slightly projected from the beam 2. In the figure, 10 indicates the waist wall.

Furthermore, a grating 9 is laid at the level of the floor 8 between the beam 2 and the outer wall 3.

As a result, in summer, direct solar radiation is blocked by the outer edge of the light shelf 6 and does not reach the inside of the beam 2 at the level of the floor 8 but the space 4 outside the window 5. The solar radiation is shielded at the part.

As a result of the experiment, the air conditioning load in summer was cut by 35%. In addition, the maximum amount of heat that can be obtained on the south surface was 95 to 120 Kcal / hm ² without the eaves and with the blind, whereas it was 71 Kc without the blind in the case of the present invention.
It was reduced to al / hm ² .

Further, even in winter, the solar radiation is blocked by the outer end of the light shelf 6 and does not reach the window 5 above the waist wall 10, and the direct solar radiation can be shielded. Then, the sunlight hitting the inner end of the upper part of the light shelf 6 is reflected here, enters the room 7 through the window 5 as reflected light, hits the ceiling, and the lighting effect is improved.

Furthermore, since there is a grating 9 laid at the level of the floor 8 on the upper floor above the space 4, indirect light enters the window 5 through the gap of the grating 9,
The room becomes bright.

This grating 9 can be used as a passage for maintenance or disaster prevention.

And, since the light shelf 6 is positioned horizontally outside the window 5 apart from it,
The view from the window 5 is not obstructed.

[0020]

As described above, in the solar radiation shielding structure of the present invention, the eaves do not significantly project outward, the exterior appearance of the building is not impaired, it is not necessary to separately install a device such as a blind, and the window is used. The view of is not disturbed, and the solar radiation can be effectively shielded at the outer position away from the window.
