Problems solved by technology

Since this kind of structural system is constructed by the frame point method or the sticky strip method, the thermal insulation material and the base wall must form a cavity structure. The existence of this cavity structure will cause wind pressure, earthquake, and base settlement Under the influence of other factors, the external thermal insulation layer of the building's external wall will crack and fall off, and water will leak, which will seriously affect the thermal performance and safe use of the external thermal insulation of the external wall; , basically manual work, product quality and assembly can not achieve standardized management, which leaves hidden dangers to its thermal performance and safety performance

Abstract

The present invention relates to a cast-in-place hard polyurethane composite decorative plate exterior heat-insulating system and its construction process. It is characterized by that said process includes the following steps: utilizing a special composition technique to make polystyrene or hard polyurethane foam plate and fluorocarbon aluminium alloy plate or fluorocarbon inorganic plate into a kind of misplaced heat-insulating decorative plate; fixing said heat-insulating decorative plate on wall body base layer in the field by adopting three-dimensinal positioning method and invisible plastic expansion stay bolt, and forming a cavity between said heat-insulating decorative plate and wall body base layer, pouring hard polyurethane foam into said cavity so as to form adhesive heat-insulating layer; finally caulking the periphery of said misplaced composite decorative plate.

Description

Technical field [0001] The invention relates to a thermal insulation and energy-saving system for building external walls and a construction technology thereof. Background technique [0002] The existing building exterior thermal insulation technology puts forward extremely high requirements on the flatness of the exterior wall of the building envelope. When constructing with existing technology, leveling and plastering should be carried out on the grassroots level. This kind of plastering project that may form a hollow drum increases the construction cost and construction period, and leaves potential safety hazards. Existing external wall insulation technologies all use cement and polymer systems as their thermal insulation board bonding agents. Because this structural system adopts the frame point method or the strip bonding method, the insulation material and the base wall will inevitably form a cavity structure. The existence of this cavity structure will a...
