Anti-fall smoke exhaust skylight

Abstract

The invention relates to the technical field of buildings, in particular to an anti-falling smoke exhaust skylight. The anti-falling smoke exhaust skylight comprises fixed frames, rotating devices and clamping devices, wherein each rotating device and the corresponding clamping device are arranged at the two sides of the corresponding fixed frame respectively, one skylight body matched with each fixed frame is movably arranged between the corresponding rotating device and the corresponding clamping device, a cover plate is arranged at one end of each skylight body and provided with a first elastic part, a first clamping plate matched with each first elastic part is arranged on a clamping frame, and an electric air cylinder connected with each skylight body is rotationally arranged on the corresponding fixed frame; each clamping frame comprises an open cavity, a combined cavity and a water storing cavity, wherein a first one-way valve is arranged between the open cavity and the water storing cavity, a second one-way valve is arranged between the combined cavity and the water storing cavity, a third one-way valve is arranged between the water storing cavity and the outside, an air bag is arranged in the water storing cavity and is connected with a miniature air pump through a pipeline, and a stainless steel anti-falling net is arranged on each fixed frame. Compared with the prior art, the anti-falling smoke exhaust skylight has the advantages of being free of water leakage and water accumulation, high in seal performance, long in service life, high in safety and large in open angle.

Description

technical field [0001] The invention relates to the field of architecture, in particular to an openable skylight. Background technique [0002] The traditional smoke exhaust skylight needs to mill off part of the profile or cut off part of the waterproof rubber strip at the hinge installation position, which makes the sealing system discontinuous and increases the hidden danger of water leakage. At the same time, in order to prevent rainwater intrusion and overall structural factors, a drainage system is usually not installed on the skylight, so that once the rainwater seeps into the gap, the water cannot be removed. After a long time, the sealing strip soaked in water will accelerate aging. Once the sealing strip cannot If the sealing effect is achieved, the sunroof will leak. The more serious aging of the sealant will also cause the sealant to separate from the sunroof glass, which will easily cause the glass to break and cause serious drop accidents.

[0002] Traditional smoke exhaust skylights need to mill off part of the profile or cut off part of the waterproof rubber strip at the hinge installation position, making the sealing system discontinuous and increasing the hidden danger of water leakage

At the same time, in order to prevent rainwater intrusion and overall structural factors, a drainage system is usually not installed on the skylight, so that once the rainwater seeps into the gap, the moisture cannot be removed. After a long time, the sealing strip soaked in water will accelerate aging. Once the sealing strip cannot If the sealing effect is achieved, the sunroof will leak, and the more serious aging of the sealant will cause the sealant to separate from the sunroof glass, which will easily cause the glass to break and cause serious drop accidents
