Double-layer curtain wall

Abstract

The invention relates to the technical field of constructional engineering, in particular to a double-layer curtain wall. The double-layer curtain wall comprises a wall body and a PLC control cabinet, dirt on an outer-layer glass curtain wall is washed at high pressure by designing high-pressure spraying, a shower head type spray head of a hollow layer does not need to be replaced, and the problems that a water absorption sponge is wound around the periphery of a scraping and washing device, use has a certain service life, the water absorption sponge needs to be changed continuously, and since the water absorption sponge wound on the periphery of the scraping and washing device is mounted in the hollow layer, the replacement is inconvenient are solved; by using the interaction of high-pressure spraying and washing and a hot-air blower, the problems that the water absorption sponge is wound on the periphery of the scraping and washing device, and when glass of the hollow layer is cleaned, water and dust are prone to interacting to generate dirt to be left on the glass are solved, and drying of the hollow layer is achieved; and meanwhile, the hot-air blower is started and an upper aluminum alloy electric shutter and a lower aluminum alloy electric shutter are closed in winter, and therefore hot air generated by the hot-air blower is retained in the hollow layer to form electric heating, and the use performance of the double-layer curtain wall is greatly improved.

Problems solved by technology

[0002] The double-layer curtain wall is also called hot channel curtain wall, breathing curtain wall, ventilated curtain wall, energy-saving curtain wall, etc. Point-supported curtain wall, the inner layer can be composed of open frame, hidden frame curtain wall, or doors and windows with opening fans and maintenance channels, or glass surfaces can be set on both sides of an independent supporting structure to form a double-layer with a small space distance Facade structure, a relatively closed space is formed between the inner and outer curtain walls, the lower part has air inlets, and the upper part has air outlets, which can control the flow of air in between, with controllable air inlets, air outlets, sun visors and Venetian, etc., the current outer curtain wall is glass, because the hollow layer is provided with a ventilation channel, rainwater or water vapor or dust will enter the hollow layer through the ventilation channel, and adhere to the outer glass curtain wall inside the hollow layer, it is difficult to remove dirt, thus It affects the use effect of the double-layer curtain wall and reduces the performance of the double-layer curtain wall. At present, there is an authorized patent CN 206888280 U, which drives the scraper to move up and down in the hollow layer through a screw rod. The inside of the layer is cleaned, but the deficiencies are as follows: 1) The use of the absorbent sponge wrapped around the scraper has a certain lifespan, so it needs to be replaced continuously. Because the absorbent sponge wrapped around the scraper is installed It is inside the hollow layer, so it is inconvenient to replace. 2) The outer periphery of the scraper is wrapped with a water-absorbing sponge to clean the glass in the hollow layer. It is easy to cause the interaction between water and dust to generate dirt on the glass, resulting in incomplete cleaning, so the performance is low. , not suitable for widespread use
