Description

TECHNICAL FIELD

[0001] The utility model relates to the field of external wall heat preservation structure, and specifically relates to an external wall heat preservation composite structure. BACKGROUND

[0002] The external wall heat preservation structure mainly comprises a heat preservation layer, a decorative layer and a fixing structure, the decorative layer is fixed on the outer surface of the heat preservation layer, and the fixing structure is used for fixing the heat preservation layer and the wall body. The fixing structure is usually a Z-shaped hardware plate formed by the movable connection of two pieces, one end of the hardware plate is hung on the heat preservation layer, and the other end is fixed to the wall body through screws. For uneven wall surfaces, the distance between the two pieces of the Z-shaped hardware plate is adjusted to adapt to the wall surface. After installation, the gaps between adjacent heat preservation layers are sealed by sealing glue. The installation efficiency is low, and the overall appearance is poor.
