Heat bridge resistant complex radiation heat insulation film energy-saving decorative system and construction method thereof

Abstract

The invention relates to a heat bridge resistant complex radiation heat insulation film energy-saving decorative system and a construction method thereof, the decorative system comprises a counter radiation heat insulation layer which is adhered to a building wall body, the counter radiation heat insulation layer comprises radiation heat insulation films which are arranged piece by piece and aluminum foil adhesive tapes arranged at gaps between the adjacent two radiation heat insulation films, an adhesive layer is arranged on the outer side of the counter radiation heat insulation layer, the adhesive layer comprises a steel plate expansion net adhered to the outer side of the counter radiation heat insulation layer, a first layer of cohesive polymer mortar, which is cured with the steel plate expansion net and a second layer of the cohesive polymer mortar, which is adhered to the outer side of the first layer of the cohesive polymer mortar, and the steel plate expansion net and the radiation heat insulation films are fixed on the building wall body through heat bridge resistant heat insulation anchor bolts. The system can effectively block heat conduction, heat convection and heat radiation, reduce the impacts of an external heat environment of a building on an indoor heat environment of the building and reduce the energy consumption of the building; and the resistive heat bridge heat insulation anchor bolts can connect the system with the wall body without producing a heat bridge, and the anchoring connection is firmer.

Description

technical field [0001] The invention relates to an energy-saving decoration system for buildings and a construction method thereof. Background technique [0002] The influence of the external environment on the indoor thermal environment of a building is mainly through thermal radiation, thermal convection and thermal conduction. About 93% of the influence of the outdoor thermal environment on the room in summer comes from heat radiation, and about 7% comes from heat conduction and heat convection. About 50%-75% of the indoor heat loss in winter is through heat radiation, 45% is through heat convection, and about 5% is through heat conduction. The external insulation of external walls currently used is mainly aimed at blocking heat conduction, but there are no measures for blocking heat radiation. The traditional energy-saving decoration system for buildings, including the thermal insulation layer and the decorative surface layer, has the disadvantage that the combination ...
