Description
Technical Field
The present invention relates to a structural member for buildings.
Background
With the promotion of urbanization and agricultural modernization, the construction of agricultural houses in China is increased year by year, but the problems of poor building quality, lack of design, inconvenience, discomfort and the like generally exist and need to be solved urgently. Meanwhile, the agricultural house has short actual service life, frequent turnover and updating, large energy consumption and low energy efficiency, wastes energy resources and destroys the environment. The green agricultural house construction is promoted, the quality of agricultural house construction is favorably improved, the comfort and the safety of the agricultural house are improved, the energy conservation and emission reduction of the agricultural house are strengthened, the service life of the agricultural house is favorably prolonged, the reduction and income increase of farmers are facilitated, the livability of rural areas is improved, the construction of beautiful villages is accelerated, the green construction materials can be favorably driven to go to rural areas, and the prevention and control of regional atmosphere pollution, the adjustment of industrial structures and the upgrading of economic transformation are promoted, so that the method is imperative.
The cold-formed thin-wall section steel is widely applied in the building industry for over 60 years, can be used as main bearing components such as steel frames, trusses, beams, columns and the like, and has the advantages of light weight, high strength, flexible spatial arrangement, good earthquake resistance, short production period and the like. In recent years, with the rapid development of cold-formed thin-walled steel low-rise and multi-story houses, the structural form and the stress condition are more complicated, and a single member is often difficult to meet the design and use requirements, so that a combined section member formed by combining a plurality of single members in a connection form such as a tapping screw has been developed, and is favored by engineers in flexible and variable combination forms and good stress performance. However, the cold-formed thin-walled steel also has the problems of instability, easy buckling, unstable and firm connection between combined sections, poor fire resistance, easy corrosion and the like.
The wood as a pure natural light 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, the energy consumption of processing is low, the wood can be naturally degraded after being discarded, and the environment is not polluted. 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. On the other hand, 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 cold-formed thin-walled steel and wood are combined to make up the respective defects of the wood and the steel, and the respective advantages are exerted to the maximum extent. The existing thin-wall steel-wood combination mode mostly focuses on single-limb combination sections, is still lack of application to a plurality of combined section members, and meanwhile, the steel-wood is connected basically in a gluing mode, so that the strength and the combination efficiency are limited. Therefore, the research and development of the novel thin-wall steel-wood combined member has important significance.
