Truss-type thin day-lighting and ventilating device

Abstract

The invention discloses a truss-type thin day-lighting and ventilating device which comprises a plurality of rows of truss frameworks which are arranged on a roof ventilating opening foundation, mutually parallel and connected through connecting rods. Wind baffles are arranged on the peripheries of the multiple rows of truss frameworks, and each truss framework internally comprises two layers of V-shaped supporting structures in the vertical direction, where in the two layers of V-shaped supporting structures are evenly arranged in a mutually staggered mode in the up-down direction correspondingly. Upper-layer rain-proof plates, middle-layer rain-proof plates and lower-layer rain-proof plates which are arranged in a mutually staggered mode are arranged on the multiple rows of truss frameworks through the V-shaped supporting structures, wherein the upper-layer rain-proof plates are panels or V-shaped plates and correspond to the lower-layer rain-proof plates below the upper-layer rain-proof plates in a one-to-one mode, the middle-layer rain-proof plates and the lower-layer rain-proof plates are both V-shaped plates, and the edges of the two sides of each middle-layer rain-proof plate are partially overlapped with the corresponding upper-layer rain-proof plate and lower-layer rain-proof plate on the two sides of the middle-layer rain-proof plate. The adjacent three layers of rain-proof plates form a wind inlet, a flow passage opening and an exhaust outlet, and rain-resisting plates are arranged on the positions, located at the exhaust outlet, between every two adjacent rows of truss frameworks correspondingly. The truss-type thin day-lighting and ventilating device has the beneficial effects that the structural strength is high, the ventilating and day-lighting propertiesare good, and meanwhile the rain-and-snow-preventing function is achieved.

Description

technical field [0001] The invention relates to building environment energy-saving technology, in particular to a truss-type thin daylighting and ventilation device. Background technique [0002] Large-scale smelting plants such as electrolytic aluminum and steelmaking use open roof natural ventilation (daylighting) technology to increase ventilation and lighting environment adjustment functions. However, the current domestic roof natural ventilation and lighting technology is relatively backward. The structure of the rain and snow function is insufficient. [0003] In the national standard atlas "ventilation skylight" (05J621-3) and "ventilation skylight" (11CJ33), there are open thin ventilation skylights or thin roof ventilators, which are small ventilation units juxtaposed and low in height. roof natural ventilation. The ventilation function of the natural ventilation device is mainly determined by the size of its effective vents. Due to the lack of structural framewor...

AI Technical Summary

Problems solved by technology

The ventilation function of the natural ventilation device is mainly determined by the size of its effective vents. Due to the lack of structural framework, the structural strength is low. The serious problem of insufficient rain and snow protection function of the structure needs to increase the rain and snow protection function by increasing the overlap of the rain plate, which makes the ventilation opening of the already low ventilator even narrower, resulting in poor ventilation performance of the product
