Problems solved by technology

However, due to the on-site spraying process, the surface flatness and thickness of the insulation layer are not easy to control, so we have to use surface leveling materials that leave potential safety hazards and are incompatible with the system

Abstract

The present invention relates to a cast-in-place hard foam polyurethane composite polystyrene plate exterior heat-insulating system and its construction process. It is mainly characterized by that said construction process includes the following steps: fixing the factory-made polystyrene foam heat-insulating plate on the base layer wall body in the place by adopting three-dimensional anchoring method, and performing a cavity meeting requirement for building energy-saving rate, pouring hard foam polyurethane material in said cavity in the place so as to form adhesive heat-insulating layer of polystyrene plate; then applying face glue on the polystyrene plate heat-insulating layer and adding alkali-resisting grid fabric and applying polymer emulsion elastic water-proofing coating material, and adding polyester non-woven fabric so as to form elastic water-proofing layer and use it as finishing coating material.

Description

technical field [0001] The invention relates to the field of building energy conservation, in particular to an external thermal insulation system of a building outer protection structure and a construction process thereof. Background technique [0002] Existing polystyrene and rigid polyurethane foam boards are fixed on the base wall with cement-based adhesives in large quantities due to their excellent thermal performance. These two materials put forward extremely high requirements on the flatness of the base layer whether the frame-point method or the strip-bonding method is used in the construction of external wall insulation; in this method of bonding and fixing, the adhesive is only coated on the board. 30-50% of the area, a cavity structure that affects its safe use performance is formed between the insulation board and the base wall. Due to the existence of this cavity insulation structure, especially today when buildings tend to be high-rise,...
