Under the key field and the priority theme of green building and energy consumption reduction, the energy consumption and the pollution emission of traditional building materials such as steel, cement and the like are reduced, and the harmonious development of the building and the natural environment is an important difficult problem in the building industry. The wood as a pure natural material has the characteristics of low production cost, low energy consumption, no toxicity, no pollution and the like, and compared with carbon dioxide and energy consumption generated in the production process of materials such as concrete, cement and the like, the wood can be regenerated after cutting, has low processing energy consumption, can be naturally degraded after being discarded, does not pollute the environment, and accords with the national sustainable development strategy of building energy conservation and environmental protection. Meanwhile, the wood is an anisotropic material, has higher compressive strength and tensile strength along the grain direction, and can be regarded as a light high-strength material. The glued wood obtained by processing the primary wood through industrial treatment has the advantages of unlimited section size, dispersed defects, high available strength, free section and member shapes, availability of small-diameter wood and inferior wood, and the like. However, when a common laminated wood beam is bent, the compressive strength of the wood is not fully utilized due to the brittle failure caused by the fact that the wood at the bottom of the beam is firstly pulled apart. In addition, steel is an isotropic material having high strength and the highest ductility among all building materials, but also has some disadvantages such as easy rusting and easy buckling.
The steel-wood combined member is used for making up the respective defects of wood and steel and exerting the advantages of the wood-wood combined member to the maximum extent. From the perspective of mechanical properties, the wood member with the trapezoidal section can be used as a lateral support of steel, so that the buckling of the steel is inhibited, the structural instability is prevented, the steel member can make up the defects of bending resistance and strength of the wood member with the trapezoidal section, and the overall rigidity of the structure is improved; from the perspective of architecture, the wood has a more natural appearance, so that the wood gives more visual and comfortable experience to residents, and improves the habitability of houses; in other properties, wood is used as an excellent thermal insulation material, so that the thermal insulation performance of the building house can be greatly improved, meanwhile, the fire resistance of the wood is stronger than that of steel, and the integral supporting time of the steel-wood combined structure is longer than that of a steel structure house in the same fire environment. In conclusion, the research and development of the novel steel-wood combined component furthest exert the respective advantages of steel and wood, so that the steel-wood materials are well coordinated and matched, the novel steel-wood combination is green, and the building system has important economic value, ecological value and social significance.
The invention content is as follows:
