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...

Embodiment Construction

[0016] The structure disclosed in the above drawings is a structure of an embodiment of the present invention. In the figure, 1 is the base layer of the exterior wall of the building that does not need to be leveled; 2 is the interface layer; 3 is the cast-in-place rigid polyurethane adhesive insulation layer; 4 is the invisible plastic expansion anchor; 5 is the dislocation-shaped composite decorative board.

[0017] With reference to the drawings, the external thermal insulation system of the present invention for the cast-in-place rigid polyurethane composite decorative panel includes a base layer 1, an interface layer 2, a field-cast rigid polyurethane bonding thermal insulation layer 3; an invisible plastic expansion anchor is used on the outside of the bonded thermal insulation layer 3 The bolt 4 and the three-dimensional positioning method are provided with a dislocation-shaped thermal insulation decorative board 5, and finally the dislocation-shaped thermal insulation deco...
