Construction method of heat-preservation outer wall

Abstract

The invention relates to a construction method of a heat-preservation outer wall. The construction method comprises the following steps: S1, the outer wall is cleared, and a levelling layer is smearedon the outer wall; S2, an L-shaped supporting piece used for supporting heat-preservation plates is arranged on the outer wall every three or more layers of heat-preservation plates; S3, an adhesiveis smeared on the levelling layer, the heat-preservation plates are pasted to the outer wall, and the heat-preservation plates are supported layer by layer through the supporting pieces; S4, an innerglass bead mortar layer is smeared on the heat-preservation plates, a galvanized steel wire mesh is fixedly arranged outside the inner glass bead mortar layer, and an outer glass bead mortar layer issmeared outside the galvanized steel wire mesh; and S5, a layer of alkali-resistant glass fiber gridding cloth is arranged outside the outer glass bead mortar layer and fixed through expansion bolts driven into the outer wall, an anti-cracking mortar layer is smeared outside the alkali-resistant glass fiber gridding cloth, then trowelling and curing are conducted, and finally a facing layer is laid. The construction method has the advantages of good heat-preservation effect and cracking prevention.

Description

technical field [0001] The invention relates to the technical field of exterior wall construction, in particular to a construction method for thermal insulation exterior walls. Background technique [0002] With the development of social economy and the process of urban construction, energy is a precious resource for human beings to survive. Energy shortage has become a global problem. Vigorously promoting building energy conservation is an important part of our energy conservation, and vigorously advocating the innovation of wall insulation and insulation materials is the current development trend. Enterprises can only seek development through constant exploration and innovation. [0003] In recent years, there have been some projects that have carried out wall insulation construction, and the insulation effect is not good, and the outer surface of the wall insulation layer is cracked. All the above situations will definitely affect the development of my country's exteri...
