Integrally prefabricated multifunctional composite external wall panel and industrial building external wall

Abstract

The invention discloses an integrally prefabricated multifunctional composite external wall panel and an industrial building external wall. The external wall panel comprises an outer decoration layer, a reinforcing bar fine aggregate concrete structural layer, a light-weight heat insulation layer and an indoor decoration layer which are fixedly connected from the outside to the inside, wherein the reinforcing bar fine aggregate concrete structural layer is filled into the light-weight heat insulation layer for forming plate ribs; heat insulation pads are arranged on the end surfaces of the plate ribs; first connecting elements are arranged on the periphery of the external wall panel; the top and the bottom of the external wall panel are respectively provided with positioning mechanisms; the top of the external wall panel is provided with hanging rings; and pre-buried accessories are arranged in the external wall panel. The external wall is formed by the external wall panels through vertical and horizontal distribution, surrounding and shielding, the periphery of each external wall panel is provided with a connecting mechanism connected with a main body stress component; the back part of the connecting mechanism is pre-buried in the reinforcing bar fine aggregate concrete structural layer of the external wall panel; and the adjacent external wall panels are sealed and connected through telescopic sealing elements. The integrally prefabricated multifunctional composite external wall panel and the industrial building external wall have the advantages that the industrial production can be realized; the weight is light; the transportation and the construction are convenient; the heat insulation performance and the sound isolation performance are good; the intensity and the weatherability are good; the internal and external decoration construction is not needed; and the installation is convenient.

Description

technical field [0001] The invention belongs to the technical field of buildings, and relates to an industrially produced exterior wall panel of a new type of green building, in particular to an integrally prefabricated multifunctional composite exterior wall panel and an exterior wall of an industrialized building. Background technique [0002] The current building construction mainly adopts the construction method of on-site wet work. The on-site wet work construction consists of setting up formwork and erecting frames on site, pouring reinforced concrete stress structures, building internal and external walls of masonry blocks, and plastering the surface. Finishing and other processes are realized. There are some high-rise (or super-high-rise) public (office) housing buildings that use steel structures as the building’s stress structure system, profiled steel plate cast-in-place concrete composite floors, and glass (or metal buckle plate) curtain wall exterior walls.

AI Technical Summary

Problems solved by technology

[0003] Houses built by wet work on site have many procedures, long cycle time, time-consuming, heavy self-weight, and must build construction frames; a large amount of construction dust is generated to pollute the environment; the glass material of the outer wall of the glass curtain wall is an energy-consuming material and produces light pollution

The existing technology promotes a P.C prefabricated panel house with external hanging and internal pouring. In this technology, only the industrialization of the external wall of the building is realized, and the on-site pouring is changed to pouring concrete in the factory to form an external wall panel, which is transported to the site for installation. The wall panel is a full concrete structure, which is not much different from the technical performance of the previous site-cast house, but the construction cost has increased by more than 30%. This kind of prefabricated panel is heavy and difficult to hoist

In addition, after the external wall is installed, it needs to be decorated externally and internally. On-site construction still has problems such as time-consuming, high-altitude operation safety, and the quality of on-site construction is not uniform.
