High-rise ultralow-energy-consumption residence outer wall composite external thermal insulation system and construction method thereof

Abstract

The invention discloses a high-rise ultralow-energy-consumption residence outer wall composite external thermal insulation system and a construction method thereof. The system sequentially comprises afoundation wall body, a vacuum thermal insulation and preservation plate and a rock wool thermal preservation plate from inside to outside. the vacuum thermal insulation and preservation plate and the foundation wall body are bonded and fixed through a bonding layer, and the rock wool thermal preservation plate and the vacuum thermal insulation and preservation plate as well as the foundation wall body are bonded, anchored, combined and fixedly connected through auxiliary connecting pieces and a bonding layer; a protective layer is arranged on the outer surface of the rock wool thermal preservation plate, and two reinforcing material layers are arranged in the protective layer. The inner layer adopts the vacuum thermal insulation and preservation plate, and the outer layer adopts the rockwool thermal preservation plate, so that the thermal preservation performance and the fireproof requirement are met, and meanwhile, the thickness and the weight of an outer thermal insulation systemare reduced; a fixing mode of combining sticking and anchoring, and mainly using anchoring is adopted, the number of rock wool plate anchor bolts is 12-14/m<2> in, so that the connection is reliable,and the construction is convenient; the overall anchoring force of section thermal bridge anchor bolts is enhanced through double-layer glass fiber gridding cloth, and the crack resistance of a surface layer and the durability of an overall system are improved.

Description

technical field [0001] The invention relates to the technical field of external wall thermal insulation, in particular to an external thermal insulation system for high-rise ultra-low energy consumption residential exterior walls and a construction process thereof. Background technique [0002] Ultra-low energy consumption buildings refer to adapting to climate characteristics and natural conditions, adopting high-efficiency fresh air heat recovery technology to minimize the heating and cooling demand of buildings, and making full use of renewable Energy, buildings that provide a comfortable indoor environment with less energy consumption and can meet the basic requirements of green buildings. [0003] At present, my country is in the early stage of ultra-low energy consumption building development. Most of them are public buildings and low-rise residential projects. There are few precedents for high-rise ultra-low energy residential projects, and there is no mature experien...
