Embodiment 1

[0032] Such as figure 1 As shown, a sunshade device for natural light and ventilation comprises several regular hexagonal units closely arranged by horizontal sunshade 1 and vertical sunshade 2, and the side length of the regular hexagonal unit is 5 cm.

[0033] The angle between two adjacent horizontal sun visors 1 is 120°. A regular hexagonal unit is composed of four upper and lower horizontal sun visors 1 and two left and right vertical sun visors 2 . Two adjacent regular hexagonal units on the left and right share a vertical sunshade 2 . Each regular hexagonal unit shares a horizontal sun visor 1 with the two adjacent regular hexagonal units below it.

[0034] Overhang length L of horizontal sun visor 1 1 (m) by the side length S(m) of the regular hexagonal unit, the sun altitude angle h s (deg), sun azimuth A s (deg) and wall azimuth A ω (deg) is determined according to the following formula:

[0035] L 1 = S coth s ·cos(A s -A ω )

[0036] Overhang length L o...

Embodiment 2

[0041] Such as figure 2 , image 3 As shown, on the basis of Embodiment 1, a natural light ventilation sunshade device also includes a horizontal slide bar 3, a first connecting piece 4, a second connecting piece 6, a vertical slide bar 7 and a vertical slide bar fixed on the upper end of the vertical slide bar 7 Boss 5.

[0042] The horizontal sun visors 1 at the left and right ends are connected with the vertical slide bar 7 through the second connecting piece 6 , and the second connecting piece 6 can slide on the vertical slide bar 7 . The two uppermost second connecting pieces 6 are fixedly connected with the boss 5 on the upper end of the vertical slide bar 7 .

[0043] The vertical slide bar 7 is connected with the horizontal slide bar 3 through the first connecting piece 4, and the first connecting piece 4 can slide on the horizontal slide bar 3, so as to realize the folding and retracting of the sunshade device.

[0044] When the sunshade device was packed up, the ...

Abstract

The invention discloses a natural light ventilating and shading device. The natural light ventilating and shading device comprises a plurality of regular hexagon units formed by closely arranging horizontal shading plates and vertical shading plates. The extension lengths of the horizontal shading plates and the vertical shading plates are determined according to the side length of the regular hexagon units, design parameters of buildings and local natural geological conditions. Direct sunlight can be effectively prevented from entering a room, but scattered beams are allowed to enter the room, user view is not shielded, and indoor ventilation is not blocked during shading. In addition, building structures are not influenced, and the size can be changed according to specific conditions.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a natural light ventilation sunshade device. Background technique [0002] At present, buildings are more and more pursuing wide vision and good lighting when designing, which makes the proportion of glass surface in the envelope structure higher and higher. In office buildings with huge glass curtain walls, solar radiation heat can account for more than half of the total cooling load of air conditioners. Therefore, the expansion of glass surface area is not conducive to energy saving and emission reduction. An effective countermeasure is to add sunshade devices. The sun-shading components of the building are divided into horizontal type, vertical type, integrated type and baffle type. [0003] Traditional horizontal, vertical and integrated sunshade components will protrude for a long distance, which is not conducive to the beauty of the building. In addition, when the are...
