Description

Technical Field

[0001] The utility model relates to the technical field of shear walls, in particular to an adjustable steel plate and multi-ribbed shear wall. Background Technique

[0002] The frame-shear wall structure is a structural form widely adopted in China. The traditional frame-shear wall structure is composed of a reinforced concrete frame and a certain number of reinforced concrete shear walls. However, a series of post-earthquake investigation and statistical data in recent years show that the reinforced concrete shear walls have poor effects in resisting medium and strong earthquakes. They are completely or mostly damaged after earthquakes and cannot be repaired and strengthened, thus greatly increasing the workload of post-earthquake reconstruction. For this reason, a new type of lateral force resisting structure system, namely the embedded steel plate shear wall structure, has been developed in countries such as the United States, Japan and Canada. It is composed of a certain number of embedded steel plates in the frame. The embedded steel plates only bear the shear force transmitted along the frame beams and columns, and do not bear the vertical load of the structure. Research shows that under general wind loads and minor earthquakes, the embedded steel plates will not produce permanent deformation and can return to their original state after earthquakes; under major earthquakes, the embedded steel plates absorb and dissipate seismic energy through their own plastic deformation, thereby protecting other components to be used normally, fully reflecting the characteristics and seismic superiority of the energy dissipation and shock absorption structure, and it is an ideal structural system. In the reinforced concrete frame-shear wall structure, replacing the reinforced concrete shear wall with the embedded steel plate shear wall can improve the initial stiffness, lateral force resistance, ductility and hysteretic performance of the structure. As a new technology, in recent years in high-intensity seismic fortification areas in China, the embedded steel plate shear walls have been applied to some new construction projects and repair and reinforcement projects, and the facts show that they have good effects. The embedded steel plate shear wall has become a very promising high-rise lateral force resisting system.

[0003] In the prior art, the patent with the patent publication number CN102535679A discloses a multi-ribbed composite steel plate shear wall, which includes a plurality of rib beams and rib columns. The plurality of rib beams and rib columns form a rectangular grid structure, and embedded steel plates are arranged in each grid; the plurality of rib beams and rib columns are all made of reinforced concrete, steel reinforced concrete or all steel; the plurality of embedded steel plates are all made of ordinary low-carbon steel, high-strength steel, low yield point steel or low yield strength aluminum; the forms of the plurality of embedded steel plates are all rectangular plates, rectangular plates with vertical slits and round holes, X-shaped plates and strip-shaped plates. By changing the number of slits, hole diameter size, arc size and width of the steel plates, the ductility and stiffness of the steel plate shear wall can be conveniently adjusted, thereby improving the mechanical properties of the overall structure, and it is a superior seismic lateral force resisting component.

[0004] The above prior art increases the strength of the steel plate shear wall, but it is not convenient to quickly adjust when using shear walls with different bearing capacity requirements and different lateral force requirements. Content of the Utility Model

The plurality of longitudinal rib stud pairs 7 are arranged in a rectangular array. The plurality of longitudinal rib stud pairs 7 correspond to the plurality of longitudinal rib clamping pairs 9 one by one. Each longitudinal rib stud pair 7 includes two studs II 8. The two studs II 8 are symmetrical. The lower ends of the two studs II 8 are fixedly connected to the side of the steel plate 1.

[0021] In the first embodiment of the present utility model, six transverse rib studs are arranged horizontally for each pair of transverse rib studs 2, and five are arranged vertically for each pair. There are a total of thirty pairs of transverse rib studs 2. The transverse rib clamping pairs 4 are also arranged in a manner of six horizontally and five vertically, with a total of thirty. Each transverse rib plate 6 is clamped on six transverse rib clamping pairs 4 arranged in a horizontal row. There are a total of five transverse rib plates 6. On the other side of the steel plate 1, eleven longitudinal rib studs are arranged horizontally for each pair of longitudinal rib studs 7, and five are arranged vertically for each pair.

[0022] After the transverse rib plate 6 and the longitudinal rib plate 11 are connected, the connecting rib 12 is passed through the through hole 101, and the reinforcing ribs 13 are tied at both ends of the connecting rib 12.

[0023] After the transverse rib plate 6, the longitudinal rib plate 11, the connecting rib 12, and the reinforcing rib 13 are all connected in place, the two sides of the steel plate 1 are poured, and the connecting rib 12 and the reinforcing rib 13 are poured into the concrete to form a wall.

[0029] The second embodiment reduces the number of transverse rib plates 6 and longitudinal rib plates 11 compared to the first embodiment, thereby reducing the shear resistance and longitudinal bearing capacity of the wall.

[0030] When the use environment does not require strong longitudinal bearing capacity, the longitudinal rib plates 11 are removed at intervals before pouring, thereby weakening the longitudinal support strength. When strong transverse shear resistance is not required, the transverse rib plates 6 are removed at intervals before pouring to reduce the transverse shear resistance.
