Building external wall thermal insulation system

Abstract

The invention provides a building external wall thermal insulation system. The building external wall thermal insulation system comprises a thermal insulation layer fixed to the surface of a base layer wall body, a decorative plate arranged on the outer surface of the thermal insulation layer and a connecting piece, wherein the thermal insulation layer comprises a first thermal insulation plate and a second thermal insulation plate, one side face of the first thermal insulation plate extends outwards to form a plurality of inserting rows distributed at intervals in the vertical direction, and each inserting row comprises a plurality of protrusions; one side face of the second thermal insulation plate extends outwards to form a buckling row matched with the inserting rows, the buckling row comprises a plurality of grooves matched with the protrusions, and the first thermal insulation plate and the second thermal insulation plate are connected in an inserting mode through matching of the protrusions and the grooves; the side face, provided with the groove, of the second thermal insulation plate extends towards the first thermal insulation plate to form a surrounding plate, the surrounding plate surrounds the periphery of the first thermal insulation plate and is attached to the periphery of the first thermal insulation plate, one end of the connecting piece is fixedly inserted into the base layer wall body, and the other end of the connecting piece is used for fixing the decorative plate, and the thermal insulation layer is fixedly connected with the base layer wall body. The problems that in the prior art, a building outer wall thermal insulation system is not high in thermal insulation performance, and the thermal insulation layer is prone to falling off are solved.

Description

technical field

[0001] The invention belongs to the technical field of building exterior wall heat preservation, and specifically provides a building exterior wall heat preservation system. Background technique

[0002] The building exterior wall insulation system includes an insulation layer arranged on the exterior wall and a decorative layer arranged outside the insulation layer. At present, the external wall insulation system of buildings is mainly based on the wet plastering process, that is, the insulation layer or decorative layer is pasted on the wall through traditional polymer cement mortar, etc. This operation method makes the external wall insulation system prone to cracking, falling off, water seepage or Fire and other quality problems.

[0003] Moreover, in severe cold regions, cold regions, and passive houses that require high thermal insulation performance, the current method is to thicken the thickness of traditional external wall insulation materials. Alt...
