Problems solved by technology

[0004] The above two methods of building enclosure filling wall and its thermal insulation system have the disadvantages of heavy site work, double-sided plastering, low efficiency, long construction period, etc., and the overall cost is high.
[0005] Chinese patent, application number CN201420088945.9, adopts a fixed support frame, and integrates the thermal insulation composite wallboard with the wall. The thermal insulation composite wallboard can be constructed with reinforced concrete at the same time or can be used for filling wall construction after the reinforced concrete structure is completed. It solves the problems of the above-mentioned two types of building envelope filling walls and their thermal insulation systems, but the installation process of the thermal insulation composite wall panels is too complicated, and it is not certain that there will be no problems between the building envelope structure and the thermal insulation composite wall panels. concentrated thermal bridge

Abstract

The invention discloses a building external wall heat insulation structural system and a safety degree evaluation method thereof. The building external wall heat insulation structural system and the safety degree evaluation method thereof aim to solve the problems that concentrated thermal bridge is generated because of a connecting piece, and the life of the building wall body is short. The structure of the building external wall heat insulation structural system comprises a concrete pavement, a load-bearing structural wall, a heat insulation layer, a positioning cushion block and a connecting component. The connecting component comprises a steel wire mesh sheet and a connecting piece fixed to the steel wire mesh sheet, the connecting piece penetrates through the heat insulation layer and is fixed to the structural wall and the concrete pavement, and the positioning cushion block is used for fixing the heat insulation layer and the steel wire mesh sheet to form a steel wire mesh frame plate. According to the building external wall heat insulation structural system and the safety degree evaluation method thereof, the method for evaluating the safety degree of the building external wall heat insulation system for the first time is provided, a heat insulation wall face with the appropriate thickness is selected to be put into use according to a result calculated through the method, and moisture condensation caused by concentrated thermal bridge of the connecting piece can be effectively overcome.

Description

technical field [0001] The invention relates to a building wall thermal insulation structure system, in particular to a building exterior wall thermal insulation structure system and a safety evaluation method thereof. Background technique [0002] With the rapid development of the economy, the demand for energy is growing rapidly, and the form of energy is very severe. "Energy saving priority" has become a strategic decision for energy development. Construction efficiency and wall quality are particularly important in the construction industry. [0003] The main method of the existing building enclosure filling wall and its insulation system is: after the reinforced concrete structure is completed, the filling wall is built, plastered on both sides, and then the insulation layer is pasted on the outside; After completion, the masonry is filled with insulating blocks and then plastered on both sides. [0004] The above two methods of building enclosure filling walls and th...
