DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art In a high-rise building such as a building, as a solar shading means for shielding sunlight entering through a window, for example, an eaves is provided at an upper portion of a window to provide an eave outside an outer wall, or a blind is provided at an opening of a window. And so on.

[0003]

The method of providing the eaves on the outer wall at the upper part of the window does not allow the eaves to largely protrude outward from the outer wall, so that the shielding effect is low and the existence of the eaves is low. Often damages the appearance of the building. In the method of installing blinds, blinds are separately installed for each window, and the work of elevating and lowering according to the angle of solar radiation is required, which is troublesome and obstructs the view.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned disadvantages of the prior art, without impairing the appearance of the building, eliminating the need for separately installing blinds or the like, obstructing the view from the window, and efficiently shielding the sun. An object of the present invention is to provide a solar shading structure that can be used.

[0005]

According to the present invention, in order to achieve the above object, in a building frame composed of columns and beams, columns and beams of the building frame are provided outside the outer wall and separated from the outer wall.
A space formed between an outer wall, a column, and a beam, which is spaced apart from the beam and located below the beam, and is spaced apart from the outer wall to the outside of the window and the outer end is slightly outward from the beam. The invention is characterized in that a light shelf of a honeycomb panel is horizontally provided so as to protrude from the wall, and grating is laid at a floor level between the beam and the outer wall.

[0006]

According to the first aspect of the present invention, columns and beams are provided on the outside of the outer wall so as to be spaced apart from the outer walls, and the space is formed between the outer wall and the columns and beams, and is positioned below the beams. And, by installing a light shelf outside the window separated from the outer wall,
Since the solar radiation is shielded by the light shelf outside the window away from the window, the shielding efficiency increases. Also, the light reflected by the light shelf enters the room and the lighting efficiency is increased.

[0007] By laying grating at the floor level between the beam and the outer wall, indirect light can be dropped near the window. In addition, this grating can be used as a passage for maintenance and disaster prevention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a longitudinal sectional side view showing an embodiment of the solar shading structure of the present invention, and a case where the present invention is applied to a high-rise building such as a building will be described as an example.

In the drawing, reference numeral 1 denotes a column constituting a building frame, and 2 denotes a beam. As a basic structure of the building, an outer wall 3 is provided inside the column 1 and the beam 2 so as to be separated from the column 2 and the beam 2. A space 4 is formed between the column 1 and the beam 2. In the figure, reference numeral 5 denotes a window formed as an opening of the outer wall 3.

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

As a result, the light shelf 6 is disposed in the space 4 in a state of being suspended from the inside.
As an arrangement position, for example, on the winter solstice
The installation height is determined so that the reflected light of sunlight hitting the inner end of the upper surface of the room hits the ceiling inside the room 7, and the outer end of the light shelf 6 is placed on the summer solstice and the winter solstice. The length of the outer end of the light shelf 6 protruding from the beam 2 was determined so as to block the solar radiation into the inside of the light shelf 7 and slightly protruded from the beam 2. In the figure, reference numeral 10 denotes a lumbar wall.

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

Accordingly, in summer, direct solar radiation is blocked at the outer end of the light shelf 6 and does not enter 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 in the area.

As a result of the experiment, the air conditioning load in summer was reduced by 35%. In addition, the maximum calorific value of the south side was 95 to 120 Kcal / hm ² in the case without the eaves and with the blind, whereas in the case of the present invention, it was 71 Kcal / hm ² without the blind.
cal / hm ² .

Also in winter, the solar radiation is blocked at the outer end of the light shelf 6 and does not reach the window 5 above the waist wall 10, so that direct solar radiation can be shielded. Then, the sunlight that has hit the inner end of the upper part of the light shelf 6 is reflected here and enters the room 7 from the window 5 as reflected light, and hits the ceiling to enhance the lighting effect.

Further, since the grating 9 laid at the level of the upper floor 8 on the upper floor of the space 4 exists, indirect light enters the window 5 through the gap of the grating 9,
The room becomes bright.

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

Since the light shelf 6 is located horizontally outside the window 5 apart from the window 5,
The view from window 5 is not obstructed.

[0019]

As described above, according to the solar shading structure of the present invention, the eaves do not protrude greatly outside, the appearance of the building is not impaired, there is no need to separately install a blind or the like, and there is no need to install a blind or the like. The view of the sea is not obstructed, and the solar radiation can be efficiently shielded at an external position away from the window.
