Thermal insulation and sound absorption structure of building external wall
The present invention discloses a thermal insulation and sound absorption structure of a building external wall. The structure comprises a wall body, a rock wool layer is disposed at an inner wall of the wall body while a reflection-type thermal insulating layer is disposed at an outer wall of the wall body, the rock wool layer and the wall body are fixed by building expansion anchors disposed therebetween, a waterproof mortar layer is disposed at the other side of the rock wool layer, the reflection-type thermal insulating layer and the wall body are bonded through a bonding layer, a protective layer is disposed at the other side of the reflection-type thermal insulating layer, the reflection-type thermal insulating layer is composed of aluminum foil plates and elastic glue sticks, the aluminum foil plates are folded to be wave-shaped or zigzag, each top part of the aluminum foil plates is attached with one elastic glue stick so as to form the reflection-type thermal insulating layer, the elastic glue sticks are high-elasticity polyurethane rubber wear-resisting buffering stick pins, and the diameter and length of the elastic glue sticks are defined according to the shape of the aluminum foil plates. Under the condition of meeting strength requirements of the outer wall, the wall body has excellent inflaming-retarding and heat-shielding performance, noises in an outer wall environment are isolated at the same time, and within a certain cost range, the building outer wall can have a special functional performance.
