Outer wall light-weight heat preservation and decoration integrated plate

Abstract

The invention relates to an outer wall light-weight heat preservation and decoration integrated plate. The outer wall light-weight heat preservation and decoration integrated plate comprises a heat preservation plate, the outer surface of the heat preservation plate is coated with a light-weight reinforcing piece, the light-weight reinforcing piece is coated with mortar, and the surface of the mortar on one side of the heat preservation plate is provided with a decoration coating, so that the heat preservation and decoration integrated plate is formed, the heat preservation and decoration integrated plate is provided with an inner side face connected to a wall body and an outer side face provided with decorative coating, the heat preservation and decoration integrated plate is provided with a vent hole penetrating through the side wall of the heat preservation and decoration integrated plate, and a ventilation embedded part arranged in the vent hole. According to the outer wall light-weight heat preservation and decoration integrated plate, the formed light heat preservation and decoration integrated plate further reduces the mass of an outer wall heat preservation structure, the prefabricated ventilation embedded part penetrates through the heat preservation plate, the matching parts at the two ends of the ventilation embedded part are connected to anchoring parts of the wall body, the ventilation embedded part is provided with a ventilation cavity communicating with a plate seam, water vapor generated by the wall body can be conducted outwards, and the phenomena that the water vapor is frozen and expands, and the heat preservation decorative plate cracks and falls off are avoided.

Description

technical field [0001] The invention relates to a lightweight thermal insulation and decorative integrated panel for an exterior wall. Background technique [0002] At present, the external thermal insulation system of external walls is composed of thermal insulation layer, protective layer and fixing materials (adhesives, anchors, etc.) and is suitable for the general term of non-load-bearing thermal insulation structures installed on the outer surface of external walls. The China Building Standard Design and Research Institute stated in the "Building Structure of Exterior Wall External Thermal Insulation" that the system structure mainly includes: bonding layer, insulation layer, plastering layer, finishing layer and accessories. The finishing layer should adopt lightweight functional coatings such as finishing mortar and decorative mortar or water-based exterior wall paint with good air permeability. Existing thermal insulation layers are all made of thermal insulation b...

Problems solved by technology

In addition, the existing insulation boards need anchors to be connected to the wall to strengthen the connection between the external wall insulation system and the wall. However, some of the existing insulation boards are connected by on-site operations, and some insulation boards will prefabricate several connectors. On-site construction is connected through connectors and wall anchors, but the existing connectors have a relatively simple structure. In order to ensure the connection strength, it is often necessary to prefabricate multiple connectors around the insulation board, resulting in complex on-site construction and increased prefabrication processing The process increases the manufacturing cost of the insulation board, and the connection effect is average. This is also the reason why the external wall insulation board often cracks and falls off.
