Reliably adhered three-layer combined external wall insulation decorative board

Abstract

The invention discloses a reliably adhered three-layer combined external wall insulation decorative board which comprises a decorative board, a thermal insulation layer, a bottom plate and a mounting connecting piece, wherein the mounting connecting piece comprises rivets and a connecting plate; a V-shaped groove I is formed in the decorative board; a pit I and a pit II are formed in the thermal insulation layer; and a V-shaped groove II is formed in the bottom plate. The rivets are arranged on the bottom plate, the connecting plate is inserted into a through hole and is connected with the rivets during installation, the connecting plate is connected with a keel mounted on the external wall in advance, namely the reliably adhered three-layer combined external wall insulation decorative board disclosed by the invention can be anchored on the external wall, the installation is convenient and rapid, and the appearance of the decorative board is not damaged during installation. Moreover, the V-shaped grooves and pits are respectively formed in the decorative board, the thermal insulation layer and the bottom plate, so that the contact area among the adhesion layer, the thermal insulation layer and the bottom plate is large; and therefore, the decorative board, the thermal insulation layer and the bottom plate can be reliably adhered by glue, and the bonding strength is high.

Description

technical field [0001] The invention relates to the field of building exterior wall decoration, in particular to a thermal insulation decorative board. Background technique [0002] With the development of society, people have higher and higher requirements for the practicality, beauty, energy saving and environmental protection of building decoration materials. In these aspects, the thermal insulation and decoration integrated board has obvious advantages compared with traditional exterior wall decoration materials, making its application more and more popular. more extensive. [0003] Existing thermal insulation and decoration integrated panels generally consist of a decorative panel and a thermal insulation layer, and the thermal insulation layer is bonded to the decorative panel by glue. When installing, put glue on the insulation layer, and then stick it on the surface of the outer wall. In order to enhance the reliability of the installation, it is usually necessary t...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the object of the present invention is to provide a three-layer combined exterior wall thermal insulation and decorative panel with reliable bonding, so as to solve the problem that the installation process of the thermal insulation and decoration integrated panel in the prior art is complicated, and the decoration will be damaged by punching holes on the decorative panel. The technical problem of the appearance of the board; and solve the technical problem of the low connection strength of the thermal insulation and decoration integrated board in the prior art by using glue to bond the thermal insulation layer and the decorative board
