[0002] At present, steel structures are increasingly used in the field of building structure technology. Various new steel structures are constantly emerging and have been applied in the engineering field. The number is also increasing, and it has broad prospects. Its main advantages are: compared with concrete building structures, it has better applicability and feasibility. For example, it reduces the volume of components and increases the usable space; reduces the deadweight of the structure, reduces or completely eliminates the formwork and support required for construction; reduces embedded parts and improves seismic performance; facilitates construction and shortens construction period;

[0003] In actual engineering applications, due to the limitations of factors such as the length of steel plate component production, transportation, and even the space of the construction site, the problem of splicing steel plate walls is inevitable in engineering construction. The current conventional solution to this problem is to weld and splice different wall sections at the construction site. This solution has the advantages of direct butt joint of steel plates, good continuity of steel walls, and a simple and smooth appearance at the joints. However, this solution also has its obvious shortcomings, which are mainly manifested in: the welding process has high skill requirements for operators, and the uneven operating levels of different operators affect the stability of welding quality, posing a large quality hazard, and welding is an operation with live open flames, and there are certain safety risks in construction operations; in addition, in high-rise or super-high-rise buildings, steel plate walls are usually spliced ​​once per floor or once every two floors, which directly leads to a huge amount of seam welding work to be completed, which is labor-intensive and time-consuming, poorly economical, and inefficient.

[0006] As a further solution of the utility model: the steel plate shear wall structure includes a steel plate wall body, a circular connecting plate is welded on the outside of the steel plate wall body, and a number of reinforcing ribs are vertically staggered and fixed on both sides of the steel plate wall body. The structure needs to be welded in advance before assembly.

[0007] As a further solution of the utility model: the connecting steel plate is located between two reinforcing ribs so as to make the connecting steel plate fit tightly with the steel plate wall body.

[0008] As a further solution of the utility model: a plurality of through connection holes are opened on the side of the splicing gusset plate, and a connection through hole is opened on the side of the connecting steel plate to facilitate connection with the I-beam crossbeam and the I-beam foundation pile.

[0010] As a further solution of the utility model: the through-connecting hole and the circular hole are connected and fixed by fastening bolts and nuts, and the connecting through hole and the connecting circular hole are connected and fixed by fastening long bolts and nuts.

[0011] As a further solution of the utility model: the through-connecting hole is in the shape of a long slot, so as to adapt to I-beam beams or I-beam foundation piles of different widths.
