Precast building composite board and application structure thereof

Abstract

A precast building composite board and an application structure thereof are disclosed. The composite board comprise a multi-layer composite unit board body, and a first surface layer, a second surface layer, a middle filled inner layer, which are arranged at intervals, wherein the first surface layer, and the second surface layer are a mesh plate or a sealing plate or made of other waterproof, fireproof, heatproof and environmentally friendly materials, a decorative surface layer is arranged on the exterior of the first surface layer, the middle filled inner layer is made of a waterproof, fireproof, heatproof, and environmentally friendly filling material, the middle can be changed according to different applications, and a metal grid or a wavy steel plate can be arranged. A plurality of joint parts are arranged on the unit board body so as to connect a building structure. An outer wall, an isolation wall, or a floor of a building can be assembly quickly. The waterproof, fireproof, heatproof, heat isolation, soundproof properties, lightweight, environmental protection, and re-utilization can be realized.

Description

technical field [0001] The invention relates to the technical field of building boards, in particular to a precast building composite board and its application structure. Background technique [0002] With the rapid economic growth, the types of buildings all over the world are developing toward diversification, large-scale, and high-rise. [0003] Most of the exterior walls, floors, and partition walls of traditional buildings are made of reinforced concrete, and the building materials are heavy. In addition to the trouble of on-site construction and manufacturing, it will also increase the load bearing of the building body. When the structure is subject to earthquakes, it is easy to crack. heavy casualties. Poor waterproofness is prone to damp and water absorption to produce white blooms, and in severe cases, wall cancer will affect the quality of healthy life and living. The heat insulation effect is poor and heat will be stored, and sufficient air conditioning must be ...

AI Technical Summary

Problems solved by technology

Although there are many types of composite wallboards on the market, the actual structure is still not perfect, and the manufacturing is cumbersome and the construction is not easy. , The panel material and insulation material are easy to separate, which poses a safety hazard, and the connection with the base of the building is easy to fall off, which will shorten the service life, and the surface of the wall panel needs secondary construction for decoration, and the climate changes are easy to peel, bulge, and crack ... and other disadvantages

[0005] Therefore, whether it is a traditional reinforced concrete wall panel or a new environmentally friendly composite wall panel, the mobility of its assembly and application is poor, and most of them can only be fixed. Demolition, recycling, and reuse often require demolition and scrapping of an old house after completion, and planning and reconstruction when another new project begins. The lack of environmental protection in the process will cause unnecessary waste
