Method for external insulation construction of polystyrene board thin plastered surface in cold and windy area

Abstract

A method for external insulation construction of a polystyrene board thin plastered surface in a cold and windy area is characterized by comprising the steps of construction preparation, base surface processing, designing, line snapping, fire barrier arrangement, surface dressing and polishing, sand plastering of a bottom layer, mortar laying of gridding cloth, plastered surface mortar pouring and on-site testing and detection, 1:3 cement mortar is adopted for plastering and leveling after interface processing is conducted on a base layer, a wall is designed and divided through line snapping, an EPS board is attached with specific adhesive glue and fixed to the wall of the base layer under the assistance of an anchor bolt, detail enhancement is conducted, anti-crack mortar composite glass fiber gridding cloth is used as a protecting layer, and coating or decoration mortar serves as an external layer. Aiming at the special weather of the cold and windy area, by means of bonding between the EPS board and the wall, combination of the external layer and joint processing technology improvement, construction quality is guaranteed, a heat insulation material layer and a thin plastered surface layer are combined firmly and stably, integrality is high, the heat insulation performance of the exterior wall is improved, building materials are saved, and construction time is shortened.

Description

technical field [0001] The present invention relates to 04B general building structure; wall, for example, partition wall; roof; E04B Building construction in general; walls, for example, partitions; roofs; floors; ceilings; insulation or other protection of buildings Background technique [0002] Existing commonly used non-load-bearing building insulation boards are mainly polystyrene boards, and the surface bonding strength is poor. Not only is the surface easily damaged during construction, but also the bonding strength with the surface layer of the wall is also slightly weaker. The lack of integrity and firmness directly affects the construction progress. [0003] The mid-latitude inland area has a typical temperate continental climate. Its characteristics are: great disparity between cold and heat, dryness and less rain, more and stronger winds in spring and autumn, the maximum wind speed reaches 42m / S, and the cumulative average number of days with strong winds is 64...
