Background

An important subject of the current architectural community is the problem of building and ecological environment, concepts such as 'green building' and 'ecological building' come into play, and under the large environment of industrialization, urbanization and rapid development of new rural construction, our country puts forward a call for deeply promoting building energy conservation and accelerating development of green buildings, so that the industrialization of modern bamboo-wood structure green buildings becomes a great demand of national sustainable development.

Bamboo is produced in China, the quantity and quality of bamboo are at the top of the world, the bamboo can be regenerated and degraded, the bamboo can be made into timber in 3-5 years, the tensile strength of the bamboo is about 2 times of that of the timber, the compressive strength of the bamboo is about 1.5 times of that of the timber, the specific strength of the bamboo is higher than that of common timber, structural steel, aluminum alloy, concrete and the like, the bamboo has better elasticity and toughness and strong deformability, and the house is built by replacing concrete, steel or clay bricks and the like with the bamboo and a composite material formed by the bamboo and other materials, so that the house accords with the national green development concept.

With the acceleration of the progress of national transformation economic development mode, the development of low-carbon economy is taken as the rapid promotion of the country, the protection policy of natural forest and artificial forest culture is increasingly strict, the contradiction between the supply quantity of wood and the demand quantity of structural members is increasingly prominent, the development space of the structural members taking wood as raw material is greatly compressed, and the promotion of the biomass material members provides a direction for effectively protecting forest resources.

The rapid development of national economy brings a great deal of solid waste, and the development and utilization of the solid waste are one direction of future development.

With the rapid development of the wood member industry in China, the insufficient supply of wood raw materials becomes a main factor restricting the development of the wood members in China. The seeking of the alternative material of the wood becomes the problem which needs to be solved urgently in the development of the wood components in China. The application of the biomass material combined member with the characteristics of high quality, low price, environmental protection, low pollution, recycling and the like to replace wood raw materials inevitably has wide market space.
