Method for controlling thermal insulation layer construction by using step-type equal height thermal insulation batten

Abstract

The invention relates to walls, roof surfaces, and stilt floor slabs of industrial and civil buildings, in particular to a construction method for control insulation layers of step type equal height insulation laths. The invention is characterized in that the step type equal height insulation laths are connected on a base course wall through bonding agent to form reference control, then a polyurethane hard foam insulation layer is spray coated and a slurry material insulation layer is applied between two step type equal height insulation laths, so as to realize the effective control of the layer thickness and the overall thickness of the insulation layers. The polyurethane hard foam insulation layer is spray coated according to the height of a first step H1 of the step type equal height insulation laths, and the slurry material insulation layer is applied according to the height of a second step H2 of the step type equal height insulation laths. The width of the step type equal height insulation laths is 70 to 120 mm. The invention has the advantages that the application of the step type equal height insulation laths realizes the effective control to the thickness of the two insulation materials in the construction process; after the polyurethane hard foam insulation layer is spray coated, the surface is not required to be finished, thereby the labor intensity is reduced, the working time is saved and the environment pollution caused by construction waste generated by finishing the surface is reduced; the insulation layers have good insulation integrity and consistent thermal performance, edge joints and a hot bridge effect of large thickness insulation layers of EPS, etc. can be avoided, and the high efficiency and the energy conservation can be realized.

Description

(1) Technical field [0001] The invention relates to industrial and civil building walls, shed surfaces, and overhead floor slabs, in particular to a construction method for controlling the heat-insulation layer by step-type contoured heat-insulation slats. (2) Background technology [0002] Usually, when the polyurethane rigid foam insulation layer is sprayed, the surface flatness and line angle (yin and yang angle) accuracy is poor, and secondary repair is required. Not only wasting materials, polluting the environment, but also laborious. At the same time, it will also make the anti-crack protective layer too thick or uneven in thickness, resulting in easy cracking and excessive shear load of the insulation layer, which is not conducive to the guarantee of long-term safety and reliability. Moreover, there are also problems such as the difficulty in controlling the thickness of the insulation layer. In recent years, spraying polyurethane exterior wall insulation technolog...

[0002] Usually, when the polyurethane rigid foam insulation layer is sprayed, the surface flatness and line angle (yin and yang angle) accuracy is poor, and secondary repair is required

Not only wasting materials, polluting the environment, but also labor-intensive

At the same time, it will also make the anti-crack protective layer too thick or uneven in thickness, resulting in easy cracking and excessive shear load of the insulation layer, which is not conducive to the guarantee of long-term safety and reliability.

Moreover, there are also problems such as difficult control of the thickness of the insulation layer.
