Construction method for outer wall outer thermal insulation rock wool boards

Abstract

A construction method for outer wall outer thermal insulation rock wool boards is characterized by comprising the following steps that a, a controlling line is snapped, and a datum line is hung; b, the rock wool boards are pasted; c, a plastering layer is constructed; d, a system deformation joint is constructed; and e, an outer layer is constructed. The construction method for the outer wall outer thermal insulation rock wool boards has the advantages that the construction procedures are reasonably designed, construction is convenient, and the constructed rock wool boards are low in thermal conductivity, good in air permeability and high in combustion performance grade and can be popularized and applied to outer wall energy-saving thermal insulation projects of newly-built, extended and rebuilt residential buildings and public buildings.

Description

technical field [0001] The invention relates to a construction method of a thermal insulation layer of an external wall of a building, in particular to a construction method of an external thermal insulation rock wool board of an external wall. Background technique [0002] As my country puts 1 billion square meters of civil buildings into use every year, the proportion of building energy consumption to the total energy consumption of the whole society has risen from 10% in 1978 to 33% in 2014. The construction industry has become a major energy consumer in my country, and it continues to consume a large amount of energy, posing a serious threat to industrial energy consumption. For this reason, the country began to enforce the 50% building energy-saving standard in 1997, and vigorously developing energy-saving buildings has become a top priority. [0003] In the early 1990s, my country began to implement the thermal insulation technology for exterior walls. It has been a l...

AI Technical Summary

Problems solved by technology

However, there are also many disadvantages in the thermal insulation of the external wall: such as reducing the usable area of ​​the building; the problem of "thermal bridge" is not easy to solve; it is prone to condensation, and the thermal insulation effect is poor; it is prone to cracking of the internal thermal insulation surface; affecting the residents The second decoration of the building; the damage to the insulation layer during the decoration process is great, and a new round of construction waste is generated; the development unit can be used as a selling point, but it often does not get the support of the residents; it is not conducive to the energy-saving renovation of existing buildings

[0004] Therefore there are above-mentioned inconveniences and problems in the known external wall interior insulation construction mode
