Description

Multi-point connection structure of damping wall structure

Technical Field

The utility model relates to a shock attenuation wall structure multiple spot connection structure.

Background

The frame structure can be flexibly matched with the building plane arrangement, and is beneficial to arranging the building structure needing larger space. Meanwhile, the beam and column members of the frame structure are easy to standardize and finalize, and are convenient to adopt an assembly type structure. Therefore, the frame structure is one of the most widely used structural systems in construction engineering. In order to meet the requirements of space function separation, exterior enclosure and other building use requirements, the structure generally needs to build a filler wall in a given bay. The assembled reinforced concrete frame structure has the technical advantages of high mechanization level, energy conservation, environmental protection and the like, but the frame structure with the filler wall generally has a larger earthquake action, and the shear-resistant bearing capacity of the filler wall is lower, so that the filler wall is generally seriously damaged before a main body frame, and the function is lost. Second, the infill wall may also collapse out-of-plane when the infill wall is not connected to the frame or is not sufficiently strong. Moreover, because the filler wall restrains the deformation of the frame column, a weak layer is easily formed on the structure, and the frame column is subjected to brittle failures such as shear failure, short column failure and the like.

The existing earthquake damage investigation shows that the filler wall actually participates in earthquake shear distribution of a structural system, complex interaction exists between the filler wall and a frame structure, the shear strength of the filler wall is low, and the additional rigidity effect and the constraint effect of the filler wall often bring earthquake-resistant adverse effects and even destruction and collapse to the frame. Therefore, the academia proposes that the traditional filler wall is replaced by the shock-absorbing wall plate in the frame structure, so that the additional rigidity effect and the restraint effect of the wall body on the frame structure are reduced, and a certain amount of additional damping can be provided to consume the seismic energy. Research and application show that the assembly type damping wallboard frame structure can obviously improve the overall anti-seismic performance of the structure, reduce the self-destruction degree and has wide development prospect.

Currently, the main problem limiting the development of shock absorbing wall panels is the lack of effective connection construction measures. A connection structure of a shock-absorbing wall in the prior art, such as a connection structure for a prefabricated shock-absorbing wall panel of a frame structure disclosed in chinese utility model patent with the publication number CN207453184U, includes a flexible connection portion and a rigid connection portion, which are respectively fixed at two ends of a wall unit; the wall body unit comprises a plurality of reinforcing steel bars and two end plates, the reinforcing steel bars and the two ends are connected to form a cuboid frame, the middle of the wall body unit is provided with a reserved groove, the cuboid frame is installed in the reserved groove, when the cuboid frame is installed behind the reserved groove, the reserved groove is filled and leveled through concrete or mortar, one end of the wall body unit is fixedly connected with a frame column, and the other end of the wall body unit is filled with flexible materials between the frame column and the rigid connecting portion. However, when the frame in the connecting structure is laterally moved, the frame columns can also be subjected to bending deformation, the frame columns are subjected to bending deformation and then can push the wallboard unit to horizontally move through the rigid end, but because no gap is reserved between the wallboard unit at the rigid end and the frame columns, the bent frame columns can crush corners on the wallboard at the rigid end, and the wallboard is damaged.
