New type of plastic wood house wall structure

In recent years, a large number of plastic wood material production enterprises have emerged both domestically and internationally, exploring the design and construction of plastic wood light steel structural residential buildings. Plastic wood materials have shown excellent performance, but there are still shortcomings such as low environmental efficiency in building maintenance, poor sound insulation and insulation, long construction cycles, poor living experience, and low market recognition of plastic houses.
The wall is an indispensable and important component in wooden buildings, mainly serving as a load-bearing, enclosure, or partition space. The proportion of walls in wooden buildings is relatively large, and the wall area is usually more than twice the building area. The wall is the key to reducing complexity and simplicity in the design and construction of prefabricated buildings, and prefabricated building walls need to simultaneously consider building safety, protection, comfort, and other aspects. Building frame shear structure is a combination of frame structure and shear wall structure, which draws on their respective strengths. It can provide a large space for building layout and has good lateral force resistance performance. The application of frame shear structure in wooden buildings is still in the preliminary research stage internationally. In addition, modern wood structures are an emerging industry in China, and the construction technology and mode are basically copied from foreign countries. However, there have been no reports on the related research of integrated wood structures mainly made of plastic wood composite materials at home and abroad.
Plastic wood composite materials are a new type of material composed mainly of wood fibers and polymer plastics, mainly consisting of polyethylene plastic wood and polyvinyl chloride plastic wood. They inherit the dual advantages of plastic and wood materials, and have excellent qualities such as high strength, anti-corrosion, waterproof, fireproof, diverse structure, easy processing and connection, making them an ideal substitute for solid wood. It is widely used in indoor decoration or garden landscape products, such as outdoor plastic wood flooring, plastic wood flower racks, plastic wood pavilions, plastic wood railings, etc. With the continuous expansion of the production scale of plastic wood and the continuous improvement of the quality of plastic wood products, we continue to position our products as outdoor engineering materials or landscape small building materials with limited application value and limited beneficiary groups. How to apply high-quality plastic wood materials to modern wood structure buildings, fully utilize their excellent performance, and better serve society has become an important issue faced by the plastic wood industry.
The new type of insulated plastic wood wall structure has high shear strength, good insulation, sound insulation, and fire prevention effects, and can be modular production. It can be prefabricated in the factory and then transported to the construction site for splicing or connection to build a sound insulation plastic wood integrated frame shear wood wall for houses. The sound insulation and heat insulation plastic wood integrated frame shear wood wall includes a glued wood frame connected by glued wood columns and glued wood beams. Multiple spaced plastic wood wall bone columns are fixed in the glued wood frame, and glass fiber cotton is filled between the plastic wood wall bone columns in the glued wood frame. The outer side of the plastic wood wall bone columns is sequentially composed of directional structural particle board, breathing paper, and external hanging board. The inner side of the plastic wood wall bone columns is sequentially composed of moisture-proof film, gypsum board, and internal wall board. Sound insulation and heat insulation plastic wood integrated frame shear wood wall, with sound absorbing cotton strips installed between the outer side of the glued wood frame and plastic wood wall bone column and the oriented structure particle board. The sound insulation and heat insulation plastic wood integrated frame shear wood wall is fixed with hanging Flat noodles on the oriented structure particleboard. The hanging Flat noodles is located outside the breathing paper, and the hanging board is fixed on the hanging Flat noodles.
