Description

Steel wood bamboo composite board

Technical Field

The utility model belongs to building structure field among the civil engineering specifically indicates a can satisfy numerous service functions's such as floor, infilled wall and decking steel wood bamboo compoboard.

Background

Along with the increasingly prominent environmental problems, the environmental protection consciousness of the public is promoted, and in order to reduce the dependence on high-energy-consumption and high-pollution building materials such as clay bricks, steel products and cement, energy-saving, environment-friendly and renewable green building materials are increasingly favored by people. The wood as a renewable resource has the advantages of light weight, attractive appearance and the like, and is widely popularized, but because wood resources are not abundant in China and wood building materials popular in the market are mostly imported products, the development of the wood building materials is limited.

The bamboo wood is similar to wood and is a renewable resource, but compared with the wood, the bamboo wood has the advantages of shorter growth cycle, higher strength, better toughness, richer resources and the like, so the state strongly advocates that the bamboo replaces the wood. At present, common bamboo-wood composite materials are mainly used for manufacturing decorative floors and furniture and have the defects of insufficient bearing capacity, complex processing and the like. How to better exert the advantages of bamboo and wood is a difficult problem in the current application.

The living standard of people is improved, and the requirement for living is also improved. The traditional wall body is mostly a masonry wall body or a reinforced concrete wall body and has the defects of great weight, high pollution, complex construction and the like. Although a plurality of novel partition walls with convenient construction and light dead weight are applied at present, the novel partition walls also have some defects, such as: (1) the range of use is limited. The novel partition wall is mostly used for the function of the partition wall and cannot meet various use requirements of an inner wall, an outer wall, a bridge deck, a floor slab and the like; (2) the material is not environment-friendly. For example, the core material of the novel partition wall of the plastic plate is plastic, cannot be naturally degraded and has great harm to the environment; (3) sound insulation and poor heat insulation effect. Novel partition walls such as steel wire frame foam board partition wall adopt foam material, have the poor hidden danger of fire behavior.
