Abstract

The invention relates to an external insulation construction method for fiber polymer cement mortar composite polyphenylene plate, which pertains to an external insulation construction method for outer wall. The method comprises steps of: connecting the polystyrene plate with processed wall surface, then arranging a plane separation gap separately in terms of cutting groove on upper and lower portion of each layer of window; having downwards concave table at connection portion of the polystyrene plate, and coating fiber polymer concrete mortar on each two blocks of connection polystyrene plate, and clinging alkali-proof fiberglass mesh cloth strip on the fiber polymer concrete mortar; then spraying fiber polymer concrete mortar as protection layer. The advantages are that the mechanical degree is high, effect of artificial factor is greatly reduced, which not only resolve the problem of water-proof, but also avoids the constriction flaw. And the construction is simple, the quality is easy to handle. The invention is useful for energy saving complex wall system.

Description

technical field [0001] The invention belongs to an on-site construction method for thermal insulation of an outer wall. Background technique [0002] At present, in terms of external wall insulation, it can be roughly divided into three types of composite walls: internal insulation, external insulation and sandwich layer insulation. There are many insurmountable cold bridges in the inner thermal insulation composite wall, which seriously affect the energy saving effect and even cause condensation locally. The insulation composite wall of the sandwich layer needs to be connected by steel bars, resulting in many cold bridges. Due to the difficulty in construction of the sandwich layer, it is also prone to double-layer skin phenomenon. The external thermal insulation composite wall can reduce the thermal stress of the wall when the climate changes, completely overcome the cold bridge phenomenon of the external wall, the floor and other parts and the condensation phenomenon tha...
