Ultra-thin heat insulation composite insulation board and cast-in-place concrete composite wall and construction method

Abstract

The invention relates to an ultra-thin heat insulation composite insulation board and cast-in-place concrete composite wall, which is characterized by comprising an ultra-thin heat insulation composite insulation board, a reinforced concrete wall body and a finish coat, and the cast-in-place reinforced concrete wall body and the ultra-thin heat insulation composite insulation board outside are adhered into a whole; and the finish coat is arranged at the outer side of the ultra-thin heat insulation composite insulation board. The ultra-thin heat insulation composite insulation board and cast-in-place concrete composite wall provided by the invention has the advantages of simple construction, safety, work saving, labor saving, economy, good crack resistance, high adhesion with the wall body and long service life. The hand feeling operation and installation mode of hand smearing is eliminated, the industrialization of external insulation installation is realized, the labor intensity is reduced, and the economic and social benefits are good.

Description

technical field [0001] The invention relates to an external thermal insulation system for a building wall, specifically an ultra-thin vacuum thermal insulation composite thermal insulation board integrated with a formwork, a cast-in-situ concrete wall and a construction method thereof. technical background [0002] Building energy saving is one of the main tasks of implementing the national environmental protection and energy conservation policies. In buildings, the heat loss of the outer envelope structure is relatively large, and the wall accounts for a large proportion of the outer envelope structure. Therefore, the outer envelope structure The advancement of wall insulation technology has become an important basic technology in the field of building energy conservation. [0003] Existing external wall thermal insulation systems generally bond ultra-thin vacuum insulation panels on the surface of the poured concrete wall. Although the thermal insulation effect is good, th...

AI Technical Summary

Problems solved by technology

Ultra-thin vacuum insulation panels are easily damaged and leak air during construction. At the same time, it is time-consuming and labor-intensive to paste ultra-thin vacuum insulation panels, which increases the workload and low work efficiency. In addition, like other insulation materials, the method of pasting cannot guarantee heat preservation. system lifetime
