Laminated sheet glass curtain wall for regulating cavity vacuum degree for thermal insulation

Abstract

The invention provides a laminated sheet glass curtain wall for regulating cavity vacuum degree for thermal insulation. The curtain wall comprises a glass shell, air inlet and exhaust pipe nozzles of a cavity, a fastening seal tube and a sealant, wherein the glass shell is formed by bonding a bottom glass plate, a surface glass plate, a support and an edge sealing layer through the sealant; air inlet and exhaust pipe holes are formed on the glass shell; the edge sealing layer is closely sealed and bonded vertically along the edge of the bottom glass plate through the sealant so as to form a glass groove which takes the bottom glass plate as a bottom and the edge sealing layer as a frame; the support is vertically bonded on the bottom glass plate surface in the glass groove through the sealant; the air inlet and exhaust pipe nozzles are locked, sealed and fixed on the air inlet and exhaust pipe holes on the glass shell through the fastening seal tube; and the surface glass plate is covered on the surface of the frame of the glass groove coated by the sealant, and is bonded and sealed on the frame of the glass groove through the sealant. By the laminated sheet glass curtain wall, the vacuum degree can be adjusted so as to realize reliable operation, so that large-scale production of the laminated sheet glass curtain wall can be realized, and the energy-saving effect of a building can be achieved furthest.

Description

technical field [0001] The invention relates to a laminated flat glass curtain wall for regulating and controlling the vacuum degree of a chamber and belonging to the field of building materials. Background technique [0002] Vacuum glass is supported by an interlayer between two layers of glass plates, and the surrounding area is vacuum sealed by bonding. Due to its excellent sound insulation, heat insulation effect and good strength, it is widely used in high-end buildings. Since the periphery of the vacuum glass is bonded by low-temperature glass fusing, its manufacture, cost and size are greatly limited, and it is difficult to temper the glass plate, which affects the strength and safety performance. Once the glass is fusing If the vacuum leakage is damaged due to stress and other reasons, the entire vacuum glass will lose its good sound insulation and heat insulation performance. Another kind of vacuum glass is supported by an interlayer between two layers of glass pla...

AI Technical Summary

Problems solved by technology

However, the vacuum glass bonded with various sealants will fail in long-term operation and lose the vacuum, thus losing its due good performance.

It is difficult to adjust when good sound insulation and thermal insulation are not required.
