Prefabricated non-bearing external wall panel and preparation method thereof

Abstract

The invention provides a prefabricated non-bearing external wall panel and a preparation method thereof, and relates to the technical field of buildings. According to the prefabricated non-bearing external wall panel and the preparation method thereof, the factory prefabrication rate of a building external wall can be greatly improved, procedures are reduced, the construction period is shortened,the overall mass is light, and convenient installation is achieved. The external wall panel comprises a plate rib network and a thin plate, wherein the plate rib network comprises transverse plate ribs and vertical plate ribs which are arranged in a criss-cross mode, and the transverse plate ribs and the vertical plate ribs are fixedly connected; one surface of the plate rib network is fixedly connected with the inner surface of the thin plate; and a heat preservation plate is arranged at the hollow part of the plate rib network, wherein the inner surface of the heat preservation plate is fixedly connected with the inner surface of the thin plate, and the side surface of the heat preservation plate is fixedly connected with the plate rib network. According to the technical scheme, the prefabricated non-bearing external wall panel and the preparation method thereof are suitable for the building process of a non-bearing wall.

Description

【Technical field】 [0001] The invention relates to the technical field of construction, in particular to a prefabricated non-load-bearing exterior wall panel and a preparation method thereof. 【Background technique】 [0002] Most of the non-load-bearing exterior walls of existing buildings are: hollow blocks, aerated concrete blocks, etc. or aerated concrete light-duty slats and other cement-based light-weight wall panels. Both hollow blocks and aerated concrete blocks have the advantage of realizing the light weight of the external wall, but the masonry method does not conform to the prefabricated building; aerated concrete light slats and other cement-based lightweight wall panels have the ability to meet the requirements of prefabricated buildings. Advantages, but due to the low strength of this type of plate, the reliability of the connection node with the structure is relatively poor. In addition, due to the relatively low strength of the above-mentioned materials, when ...

AI Technical Summary

Problems solved by technology

Both hollow blocks and aerated concrete blocks have the advantage of realizing the light weight of the outer wall, but the masonry method does not conform to the prefabricated building; the aerated concrete light-weight slats and other cement-based lightweight wall panels have the ability to meet the requirements of prefabricated buildings. Advantages, but due to the low strength of this type of plate, the reliability of the connection node with the structure is relatively poor

In addition, due to the relatively low light weight and strength of the above materials, when the dry method is used for exterior decoration, the connection stability with the exterior wall is poor; when the wet method is used for exterior decoration, the thermal performance of the decoration material and the wall material is quite different, and delamination problems are prone to occur
