Description

Technical Field

[0001] The present application relates to the technical field of connection between steel bars and rigid structures, and in particular to a connection structure between steel bars and rigid structures. Background Art

[0002] Rigid structure is a main form of steel and concrete composite structure. It is a special composite material formed by adding steel to reinforced concrete. Since the steel core is like a skeleton, it can effectively improve the ductility of concrete and greatly improve the seismic performance of concrete. The lateral constraint of concrete on steel ensures the mechanical properties of steel and will not be withdrawn from work prematurely due to instability. Due to its high bearing capacity, high rigidity, good fire resistance and good seismic performance, it has been increasingly used in large-span structures and high-rise buildings and super high-rise buildings in earthquake zones.

[0003] In traditional construction, steel bar rigid structures generally adopt opening measures, but the opening measures are prone to stress concentration, and the opening positions are difficult to determine. If all sleeve connections are used, the investment is large. Therefore, improvements are now made to a connection structure between steel bars and rigid structures. Utility Model Content

[0006] By adopting the above technical scheme, the end of the steel bar without external thread is fixedly connected to the main body of the steel column through the reinforcement plate, and the end of the steel bar with external thread is fixedly connected to the main body of the steel column through the steel sleeve. By combining the steel sleeve and the reinforcement plate, the steel bar connection requirements are met and the use of the steel sleeve is reduced, saving costs while ensuring stable connection.

[0007] As a preferred technical solution of the present application, the outer surfaces of one end of several of the steel bars away from the reinforcement plate are provided with external threads, the inner walls of several of the steel bar sleeves are provided with internal threads, the end of the steel bar provided with the external threads is located inside the steel bar sleeve, and the internal threads are adapted to the external threads.

[0008] By adopting the above technical solution and setting matching internal threads and external threads, necessary conditions are provided for the threaded connection between the steel bar and the steel bar sleeve.

[0009] As a preferred technical solution of the present application, the number of the steel bars is consistent with the number of the steel bar sleeves and corresponds one to one.

[0010] By adopting the above technical solution, the one-to-one corresponding steel bars and steel bar sleeves ensure the smooth installation of each steel bar.

[0011] As a preferred technical solution of the present application, the upper surface of the rib plate is fixedly connected to a limiting block, a fixed steel bar is inserted into the limiting block, and the bottom of the fixed steel bar fits with the top of the steel bar.

[0012] By adopting the above technical solution, the steel bars can be limited and fixed, making it easier for workers to weld the steel bars to the reinforcement plates.

[0013] As a preferred technical solution of the present application, a support block is provided at the bottom of the rib plate. The cross-section of the support block is triangular. A mounting hole is opened inside the support block. The internal thread of the mounting hole is connected with a fixing bolt. The number of the support blocks is twice the number of the rib plates. The support blocks are fixedly connected to the rib plate and the steel column body by fixing bolts respectively.

[0014] By adopting the above technical solution, the support blocks play a role of reinforcing support. The support blocks can enhance the stability of the ribbed board, making the ribbed board more resistant to bending. The support blocks can also share the load of the ribbed board, reducing the load of the ribbed board to a certain extent.

[0015] As a preferred technical solution of the present application, the rib plates, limit blocks and support blocks are all made of galvanized metal materials.

[0016] By adopting the above technical solution, the overall strength of each structure can be strengthened to prevent damage and prolong the service life.
