Reinforcement cage with enhanced anti-seismic property

Abstract

The utility model relates to the field of building structures, in particular to a reinforcement cage with enhanced anti-seismic performance. According to the technical problems, in the process that a building is affected by vibration, a reinforcement cage buried in a concrete bearing structure can resist shearing force borne by the bearing structure so as to avoid cracking and damage of the concrete structure, however, the structural strength of the reinforcement cage is relatively limited, and the risk of damage to the concrete bearing structure is still large when vibration with high resistance strength is resisted. According to the technical scheme, the reinforcement cage with the enhanced anti-seismic performance comprises a bundling assembly, a connecting assembly and a reinforcement cage body. By arranging the double-end stabilizing mechanism and the fixed traction mechanism, the reinforcement cage laid in the concrete bearing structure can be more effectively combined with concrete, so that the anti-seismic property of the reinforcement cage is improved, the reinforcement cage is more difficult to loosen when bearing shearing force generated by vibration, and the service life of the reinforcement cage is prolonged. The probability that a bearing structure of a building is damaged due to vibration is reduced.

Description

Technical Field

[0001] The utility model relates to the field of building structures, and particularly relates to a steel reinforcement cage with enhanced seismic performance. Background Art

[0002] A steel reinforcement cage is a prefabricated steel bar mesh structure commonly found in concrete structures. Its main function is to enhance the bearing capacity and tensile strength of concrete components. Steel reinforcement cages are mainly used in the construction of concrete structures such as bridges, tunnels, and high-rise buildings. In these structures, the steel reinforcement cage is usually installed in a predetermined position by machine punching or water jet drilling, and then concrete is poured through a conduit. This can effectively combine the concrete with the steel bars and improve the overall stability and bearing capacity of the structure. After the building is affected by vibrations, the steel reinforcement cage buried inside the concrete load-bearing structure will resist the shear force received by the load-bearing structure to prevent the concrete structure from cracking and being damaged. However, the structural strength of the steel reinforcement cage is relatively limited, and when resisting vibrations of relatively high intensity, the risk of damage to the concrete load-bearing structure is still relatively high. Content of the Utility Model

[0003] In order to overcome the problem that during the process of a building being affected by vibrations, the steel reinforcement cage buried inside the concrete load-bearing structure will resist the shear force received by the load-bearing structure to prevent the concrete structure from cracking and being damaged, but the structural strength of the steel reinforcement cage is relatively limited, and when resisting vibrations of relatively high intensity, the risk of damage to the concrete load-bearing structure is still relatively high.

[0004] The technical solution of the utility model is: a steel reinforcement cage with enhanced seismic performance, including a constriction component, a connection component, and a steel reinforcement cage main body; the connection component is inserted into the constriction component; the steel reinforcement cage main body is fixedly connected to the connection component.

[0005] Preferably, the constriction component is used to improve the stability of the upper and lower ends of the steel reinforcement cage, the connection component is used to connect the steel bars and improve the stability of the steel reinforcement cage, and the steel reinforcement cage main body is used to improve the seismic performance of the load-bearing structure.

[0006] Preferably, the constriction component includes constriction rings, insertion holes, outer friction grooves, and inner friction grooves; there are two constriction rings; a plurality of insertion holes are respectively formed in the constriction rings. When building the steel reinforcement cage, the longitudinal bars are inserted into the insertion holes of the constriction rings and the slots and docking grooves of the connection blocks, and the spiral bars are fixedly connected to the longitudinal bars and the spiral grooves.

[0007] Preferably, a plurality of outer friction grooves are respectively formed on the outer sides of the constriction rings; a plurality of inner friction grooves are respectively formed on the inner sides of the constriction rings. After the concrete solidifies, the outer friction grooves and the inner friction grooves will increase the contact area between the constriction rings and the concrete to improve the friction force between the constriction rings and the concrete.

[0008] Preferably, the connecting component includes a connecting block, a fixing plate, a slot, a docking groove, a spiral groove, a pulling frame, a longitudinal feeding groove, a transverse feeding groove, and a third friction groove; a plurality of connecting blocks are arranged inside the converging ring; fixing plates are fixedly connected to the inner sides of the connecting blocks; two slots are respectively formed inside the connecting blocks. During the process of pouring the concrete load-bearing structure, the concrete is filled into the pulling frame through the longitudinal feeding groove and the transverse feeding groove, so that the solidified concrete can pull the connecting blocks and the steel reinforcement cage through the pulling frame to prevent the steel reinforcement cage from loosening due to vibration, thereby improving the stability of the overall structure.

[0009] Preferably, docking grooves are respectively formed at one ends of the slots; spiral grooves are respectively formed on the outer sides of the connecting blocks, and the docking grooves are communicated with the spiral grooves; pulling frames are fixedly connected to the inner sides of the fixing plates. The third friction groove is used to increase the contact area between the pulling frame and the concrete, so as to increase the friction force between the pulling frame and the concrete.

[0010] Preferably, longitudinal feeding grooves are respectively formed at the upper and lower ends of the pulling frame; transverse feeding grooves are respectively formed on both sides of the pulling frame; a plurality of third friction grooves are formed on the pulling frame.

[0011] Preferably, the main body of the steel reinforcement cage includes longitudinal bars and spiral bars; the longitudinal bars are inserted into the insertion holes of the converging ring and the slots and docking grooves of the connecting blocks; spiral bars are fixedly connected to the outer sides of the longitudinal bars.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. By providing a double-end stabilizing mechanism and a fixed pulling mechanism, the steel reinforcement cage laid in the concrete load-bearing structure can be more effectively combined with the concrete, so as to improve the seismic performance of the steel reinforcement cage, making the steel reinforcement cage less likely to loosen when bearing the shear force generated by vibration, thereby reducing the probability of damage to the load-bearing structure of the building due to vibration;

[0014] 2. When building the steel reinforcement cage, insert the longitudinal bars into the insertion holes of the converging ring and the slots and docking grooves of the connecting blocks, and fix the spiral bars to the longitudinal bars and the spiral grooves to complete the construction of the steel reinforcement cage. Then pour the concrete at the position where the steel reinforcement cage is located. After the concrete solidifies, the outer friction groove and the inner friction groove will increase the contact area between the converging ring and the concrete, so as to increase the friction force between the converging ring and the concrete, thereby improving the stability of the steel reinforcement cage and further enhancing the seismic performance of the steel reinforcement cage;

[0015] 3. During the process of pouring the concrete load-bearing structure, the concrete is filled into the pulling frame through the longitudinal feeding groove and the transverse feeding groove, so that the solidified concrete can pull the connecting blocks and the steel reinforcement cage through the pulling frame to prevent the steel reinforcement cage from loosening due to vibration, thereby improving the stability of the overall structure. The third friction groove will increase the contact area between the pulling frame and the concrete, so as to increase the friction force between the pulling frame and the concrete, thereby improving the stability of the steel reinforcement cage and further enhancing the seismic performance of the steel reinforcement cage.

The restraint assembly 1 includes a restraint ring 101, insertion holes 102, outer friction grooves 103, and inner friction grooves 104; there are two restraint rings 101; a plurality of insertion holes 102 are opened in each restraint ring 101. When building the steel reinforcement cage, the longitudinal bars 301 are inserted into the insertion holes 102 of the restraint ring 101, the slots 203 and the docking grooves 204 of the connection blocks 201, and the spiral bars 302 are fixedly connected to the longitudinal bars 301 and the spiral grooves 205. A plurality of outer friction grooves 103 are opened on the outer sides of the restraint rings 101; a plurality of inner friction grooves 104 are opened on the inner sides of the restraint rings 101. After the concrete solidifies, the outer friction grooves 103 and the inner friction grooves 104 will increase the contact area between the restraint ring 101 and the concrete to improve the friction between the restraint ring 101 and the concrete.

[0025] Please refer to Figure 3-6 , in this embodiment, the connection assembly 2 includes connection blocks 201, fixing plates 202, slots 203, docking grooves 204, spiral grooves 205, pulling frames 206, longitudinal feeding grooves 207, transverse feeding grooves 208, and third friction grooves 209; a plurality of connection blocks 201 are arranged in the restraint ring 101; fixing plates 202 are fixedly connected to the inner sides of the connection blocks 201; two slots 203 are opened inside the connection blocks 201. During the process of pouring the concrete load-bearing structure, the concrete is filled into the pulling frames 206 through the longitudinal feeding grooves 207 and the transverse feeding grooves 208, so that the solidified concrete can pull the connection blocks 201 and the steel reinforcement cage through the pulling frames 206 to prevent the steel reinforcement cage from loosening due to vibration, thereby improving the stability of the overall structure. Docking grooves 204 are opened at one ends of the slots 203; spiral grooves 205 are opened on the outer sides of the connection blocks 201, and the docking grooves 204 communicate with the spiral grooves 205; pulling frames 206 are fixedly connected to the inner sides of the fixing plates 202. The third friction grooves 209 are used to increase the contact area between the pulling frames 206 and the concrete to improve the friction between the pulling frames 206 and the concrete. Longitudinal feeding grooves 207 are opened at the upper and lower ends of the pulling frames 206; transverse feeding grooves 208 are opened on both sides of the pulling frames 206; a plurality of third friction grooves 209 are opened on the pulling frames 206.

Then, pour concrete at the location where the steel cage is located. After the concrete solidifies, the outer friction grooves 103 and the inner friction grooves 104 will increase the contact area between the converging ring 101 and the concrete, so as to increase the friction force between the converging ring 101 and the concrete, thereby improving the stability of the steel cage and further enhancing the seismic performance of the steel cage.

[0027] During the process of pouring the concrete load-bearing structure, the concrete fills into the tension frame 206 through the longitudinal feeding groove 207 and the transverse feeding groove 208, so that the solidified concrete can pull the connecting block 201 and the steel cage through the tension frame 206 to prevent the steel cage from loosening due to vibration, thereby improving the stability of the overall structure. The third friction groove 209 will increase the contact area between the tension frame 206 and the concrete, so as to increase the friction force between the tension frame 206 and the concrete, thereby improving the stability of the steel cage and further enhancing the seismic performance of the steel cage.

[0028] Through the above steps, a double-end stabilizing mechanism and a fixed tensioning mechanism are set up, so that the steel cage laid in the concrete load-bearing structure can be more effectively combined with the concrete to improve the seismic performance of the steel cage, so that the steel cage is less likely to loosen when bearing the shear force generated by vibration, thereby reducing the probability of damage to the load-bearing structure of the building due to vibration.
