The single steel plate composite shear wall is mainly connected in an all-welded or all-bolted mode, bolt-welded mixed connection is generally not considered, welding labor cost is high, quality is not guaranteed, bolt connection has high requirements on construction, bolt connection nodes with low precision are difficult to install subsequently, and the phenomenon of 'untwisting' is easy to occur in traditional bolt connection.
The double-steel-plate composite shear wall is strong in vertical bearing capacity, is mainly applied to a super high-rise mixed structure system, and compared with a single-steel-plate composite shear wall, the double-steel-plate composite shear wall needs to consider the connection between two steel plates and the cooperative work of the double steel plates and concrete in addition to the connection between wall beams and wall columns. The stud is the most commonly used connection mode for ensuring the synergy of the steel plate and the concrete, and the stud is formed by punching a hole in the steel plate, penetrating the stud into the concrete, fixing the stud by utilizing the friction and the embedding action of the stud and the concrete, and penetrating the stud through the steel plates on two sides, thereby ensuring the synergy of the double steel plates and the internally filled concrete.
In summary, the conventional bolting method mainly has the following disadvantages: (1) the pre-tightening force of the bolted joint is easy to lose and can not reach the expected pre-tightening force; (2) the bolted joint is also broken, so that the cooperative work of the steel plate and the concrete is influenced; (3) the ends of the pegs extend to the steel plate, resulting in uneven steel plate surfaces; (4) the subsequent maintenance difficulty is high; (5) the requirement on the construction precision is high.
In order to solve the above problems, people are always seeking an ideal technical solution.
