Description
Technical Field
The patent relates to the technical field of civil engineering, in particular to a novel steel-wood/bamboo combined assembly type structure system.
Background
The global environmental problem is a focus, the energy consumption of the building industry is a big household of global total energy consumption, the influence on the environment is different, and the development of the building is vital only based on energy conservation and environmental protection. The search for sustainable development, environment-friendly building materials and the research of novel structural systems become a new direction for the development of the civil engineering field at present.
The wood/bamboo material is an ideal building material which is recognized at present as green, high-strength, environment-friendly and renewable, wood resources in China are not very rich, but the bamboo material is a second forest name in China. The growth cycle of the wood is much longer than that of the bamboo, although poplar and other fast-growing forests are developed, the fast-growing forests as structural materials are softer in texture and weaker in mechanical property and can only be used as secondary components. The bamboo can be made into timber in 3-5 years, has many excellent characteristics of hard broad-leaved trees, and has light weight and good heat preservation performance, so that the specific strength and specific rigidity of the wood/bamboo are higher than those of steel, and the wood/bamboo is an ideal green, energy-saving and short-period building material. The environmental load of wood and bamboo is far less than that of traditional building materials such as steel, concrete and the like. Because the wood and bamboo have irregular geometric dimensions and the mechanical properties are greatly influenced by the types, the growing geographical positions and different parts, the requirements of modern buildings are difficult to meet by using the raw wood and the raw bamboo. With the rapid development of the adhesive, the industrial wood products and the bamboo products are developed vigorously, and the industrial wood/bamboo products not only have excellent, uniform and stable mechanical properties, but also can meet the requirements of modern buildings in external dimension. However, the elastic modulus of the industrial wood/bamboo products is small, the strength is still large, and the deformation of the components cannot meet the requirements of normal use. The steel has high strength and high elastic modulus, and is a light high-quality building material. Therefore, the structural steel is used as a main bearing member beam and column, and the industrial wood/bamboo is used as a floor system, a roof system and a wall structure to form a novel environment-friendly, high-strength, light-weight and high-strength steel wood/bamboo combined structure system.
China is located at the junction of the European and Asian seismic zones and the Pacific seismic zone of the two major seismic zones in the world, the earthquake disaster is serious, and the earthquakes in continents of China have the characteristics of high frequency, wide distribution, shallow seismic source, high strength and high disaster rate. Therefore, seismic fortification is always the direction of the structural design of house buildings in China. As for the current domestic and foreign research results, the steel-wood/bamboo composite structure has good anti-seismic and energy dissipation capabilities due to high strength, good deformability, light weight and small earthquake action.
The main components and fittings are prefabricated in a factory according to standards and then transported to a construction site to be assembled by engineering machinery, so that the building is called as an assembly type building. With the policy promotion of the 'thirteen-five' assembly type building, the assembly type building of China is coming to spring. The assembly type building is an important carrier for building industrialization, is in transformation of building industrialization at present in China, and is a necessary trend in the long run. The prior fabricated structure mainly combines concrete and steel, but has the following defects: (1) the self weight is large, and the earthquake action is large; (2) the prefabricated part is generally large in size, high in traffic requirement on a construction site and inconvenient to transport; (3) the size of the component is determined according to the design requirement, the universality is not realized, the standardized production is not facilitated, and the production cost of a prefabricated part manufacturer is higher; (4) the concrete has high energy consumption and great pollution, is difficult to recycle after reaching the service life, and does not conform to the policy guidance of the prior energy-saving emission-reducing green building.
With the rapid development of wood structure buildings in China in recent years, the country ranks the construction of multi-story high-rise wood structures and assembled green environment-friendly building structures as the development direction of the building industry in China. The steel-wood/bamboo combined structure system takes the steel section which is industrialized at present as a beam column to form a main body bearing frame structure, and industrial wood/bamboo products which can realize factory standardization prefabrication are taken as floor systems, roof systems and wall structures and are embedded in structural units of the steel section frame. Therefore, the combined structure can realize an assembled green building structure, realize the factory building of house buildings, save the labor cost and relieve the situation of increasingly lacking labor. It is therefore highly desirable to overcome the above-mentioned deficiencies of conventional fabricated structures based on concrete and steel materials by providing a novel fabricated structural system of steel wood/bamboo combination.
