Description
Technical Field
The invention relates to the technical field of building structures, in particular to a steel beam and reinforced concrete shear wall node for a fabricated mixed structure house.
Background
The steel structure building has the advantages of factory prefabricated member, fast construction speed, low cost, small self weight, etc., so that it is one of the structural forms meeting the requirement of industrial development of building and may be used widely in middle and high storey assembled house.
For a traditional steel frame structure house, a steel column is a main lateral force resisting component, steel supports are generally required to be additionally arranged in the structure along with the increase of the building height, and meanwhile, the section size of the steel column is increased to improve the rigidity of the structure, so that the displacement of the structure under the action of horizontal earthquake load is reduced, the phenomenon that the beam is exposed and the column is exposed in a steel frame house room is caused, the living environment is influenced, and the actual building area in the house is reduced. The prefabricated mixed structure house formed after the precast concrete shear wall is introduced into the steel frame house not only can retain the advantages of large structural space and high construction speed of the original steel frame house, but also can greatly improve the structural rigidity and avoid increasing the section sizes of lateral force resisting members such as steel columns, steel supports and the like; the precast concrete shear wall has good heat preservation, waterproof, sound insulation and anti-seismic performance as an outer enclosure of a structure and a main lateral force resistant component. Therefore, the assembled mixed structure house integrates the advantages of the steel frame structure and the reinforced concrete shear wall structure, and has wide development prospect.
The reinforced concrete shear wall and the steel frame are used as core components of the prefabricated mixed structure house, and the effective connection between the steel beam and the reinforced concrete shear wall is the key for realizing the cooperative stress of the two core components and is also the difficulty for designing and building the prefabricated mixed structure house. The traditional steel beam and reinforced concrete shear wall joint usually adopts the following connection form: (1) the steel beam directly extends into the reinforced concrete shear wall; (2) embedding a steel column in the reinforced concrete shear wall, and connecting the steel beam with the embedded steel column; (3) and arranging an embedded part in the reinforced concrete shear wall, and connecting the steel beam with the embedded part. The three connection modes are mainly provided based on a steel frame-reinforced concrete core tube structure, and because the thickness of the shear wall forming the reinforced concrete core tube is generally large, the concrete pouring in the shear wall cannot be influenced by adopting the connection mode that the steel beam extends into the shear wall or the embedded steel column. However, as a shear wall used in an assembled mixed structure house, the thickness of the shear wall is generally small, if a connection mode that a steel beam extends into the shear wall or an embedded steel column is adopted, concrete pouring in a node area may be caused, coarse aggregates cannot be uniformly distributed, and the performance of a connection node of the steel beam and the reinforced concrete shear wall cannot meet design requirements. Thereby significantly affecting the construction efficiency and the construction cost.
The method for connecting the embedded parts and the steel beams in the reinforced concrete shear wall reduces the pouring difficulty of concrete in a node area to a certain extent, but the steel beams and the embedded parts in the reinforced concrete shear wall are usually connected in a welding mode after the concrete is demolded, and the high temperature generated during welding can cause concrete cracking in the shear wall and influence the safety and durability of the connection nodes of the steel beams and the reinforced concrete shear wall.
