Problems solved by technology

Existing smoke-exhaust skylights with existing structures are prone to water accumulation and freezing at the edge of the skylight, which leads to the inability to open the skylight and the failure of the fire-fighting smoke-exhaust window, thereby greatly reducing the fire-fighting and smoke-exhausting capacity, making it difficult for buildings to achieve fire-fighting and smoke-exhausting requirements, it is necessary to improve the structure of the skylight

Abstract

The invention relates to an opening fan antifreeze node suitable for a smoke-exhausting skylight. The opening fan antifreeze node comprises a window opening mechanism consisting of a fixing seat frameand a deflectable opening fan frame and is characterized by further comprising an opening frame fixedly mounted on the fixing seat frame and consisting of a hollow profile, an electric-mixing-heatingdefrosting device and a sealing strip, an opening fan fixedly mounted on the deflectable opening fan frame and consisting of a hollow profile, a double-sided adhesive paste, hollow adhesive-clampingglass, a bending profile and a sealing strip, and an outer-window deforming cavity assembly fixedly mounted on the back surfaces of the fixing seat frame and the deflectable opening fan frame and consisting of a limiting folding plate, a foam rod, a double-sided adhesive paste and a waterproof coil. According to the opening fan antifreeze node, the foam rod and the sealing strips achieves the isolate insulation and waterproof function, the fact that the internal heat does not emit outwards is ensured, a cavity is formed in an outer-window deforming cavity body, the waterproof coil and the sealing strips can deform along with the deflection of the opening fan, the requirements of an opening space are met, the requirements of water prevention and insulation are also met, and the fact that normal opening of the skylight is influenced due to freezing is avoided.

Description

technical field [0001] The invention relates to the technical field of anti-freezing technology for the opening fan of the skylight, in particular to an anti-freezing node for the opening fan specially developed to solve the problem of water accumulation and freezing at the edge of the smoke exhaust skylight, which affects the normal opening. Background technique [0002] In recent years, the requirements for indoor fire and smoke exhaust have become increasingly stringent, especially in northern regions where extremely cold weather is frequent, and the use of skylights for smoke exhaust in tall indoor spaces has become a mainstream form. Existing smoke-exhaust skylights with existing structures are prone to water accumulation and freezing at the edge of the skylight, which leads to the inability to open the skylight and the failure of the fire-fighting smoke-exhaust window, thereby greatly reducing the fire-fighting and smoke-exhausting capacity, making it difficult for buil...
