Prefabricated external thermal insulation board, thermal insulation wall formed by its assembly and construction method

Abstract

The invention provides a pre-fabricated external insulation board, a thermal-insulating wall formed by assembly thereof and a construction method of the thermal-insulating wall. One pre-fabricated external insulation board comprises an insulation board, a steel wire mesh and an anti-cracking mortar board. Upper and lower edges and four opposite angles of one insulation board are provided with transversely-connected grooves for dividing the above insulation board to be an outer surface layer and a wall-leaning layer. The steel wire mesh is fixed onto the outer surface layer of the above insulation board by means of fixing steel nails. Upper, lower, left and right edges of the steel wire mesh are larger than upper, lower, left and right edges of the wall-leaning layer of one insulation board. The anti-cracking mortar board is formed in such a manner that the outer surface of one insulation board, corresponding to the steel wire mesh, is painted with ant-cracking mortar. The thermal-insulating wall comprises a concrete external wall, longitudinal connecting pieces and transverse connecting pieces. By means of the longitudinal connecting pieces and the transverse connecting pieces, pre-fabricated external insulation boards are arrayed to be fixed onto the concrete external wall such that the thermal-insulating wall is formed.

Description

Technical field [0001] The invention belongs to the field of thermal insulation and energy saving of civil engineering buildings, and specifically relates to a prefabricated external thermal insulation board and a thermal insulation wall formed by assembly thereof and a construction method. Background technique [0002] In accordance with the requirements of the national building energy conservation planning goals, building energy conservation work must implement leapfrog development, reduce energy consumption, reduce atmospheric environmental pollution, improve building thermal comfort conditions, and promote the coordinated development of urban and rural construction, people's lives, and the ecological environment. Due to the ever-increasing demand for energy conservation and environmental protection, the insulation of building envelopes is also increasingly strengthened, and the development of external wall insulation is the fastest. After the worldwide oil crisis in 1973, ext...
