Description

Technical Field

[0001] The invention relates to the technical field of steel-reinforced concrete, and in particular to a connection structure of a steel-reinforced concrete column and a concrete beam and a construction method. Background Art

[0002] The connection structure of steel reinforced concrete column (SRC column) and concrete beam (RC beam) is a hybrid node structure, which is mainly used to reliably connect reinforced concrete columns containing steel sections inside with ordinary reinforced concrete beams in construction or bridge projects. It must meet the requirements of strength, stiffness, ductility and construction feasibility to ensure the overall safety, stability and durability of the structure.

[0003] There are many ways to connect steel-concrete columns and concrete beams. The most common connection method is to weld the longitudinal reinforcement of the beam directly to the steel, or to transition through a connecting plate (steel corbel). However, in actual operation, the welding fixation method is prone to local stress concentration at the welding site, leading to early cracking in the node area. In addition, on-site welding is easily affected by the environment and has requirements on the technical level of welding workers. While the operation is cumbersome, it is easy to produce defects such as pores, slag inclusions, and uneven welds. How to design an assembled connection structure that ensures the connection strength while eliminating the welding operation is a problem we need to solve. Summary of the invention

[0004] The invention discloses a connection structure of a steel reinforced concrete column and a concrete beam and a construction method, aiming to solve the technical problems that in the existing welding and fixing method of steel reinforced concrete columns and concrete beams, local stress concentration is easily formed at the welding part, resulting in early cracking of the node area, and the operation is cumbersome, and defects such as pores, slag inclusions and uneven welding points are easily generated.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A connection structure of a steel reinforced concrete column and a concrete beam, comprising a steel section fixed to a foundation, a connection mechanism being arranged on the outer side of the steel section, the connection mechanism comprising two quick-connection steel plates staggered and inserted and engaged with the outer side of the steel section, a threaded pipe being welded on the inner side of each quick-connection steel plate, a first through groove being penetrated through the inner side of the steel section, the threaded pipe and the first through groove being symmetrically distributed and penetrated by high-strength bolts, and the two quick-connection steel plates being fixed to the outer side of the steel section by the high-strength bolts; A reinforcement component is arranged on the outer side of the high-strength bolt; A transverse reinforcement member is provided on the outer side of each of the quick-connect steel plates; A crossbeam member is also provided on the outer side of each of the quick-connect steel plates; The connection mechanism cooperates with the reinforcement component to be stably connected to the outside of the profiled steel, eliminating the need for welding and achieving rapid connection of the transverse reinforcement member and the cross beam member.

[0006] By providing a connection mechanism, the connection mechanism is used to replace the traditional welding fixing method. The outer side of the profiled steel is clamped by two fast-connect steel plate structures that are staggered and inserted. The fast-connect steel plate is fixed by tightening high-strength bolts. At the same time, a transverse reinforcement member and a cross beam member are additionally arranged on the outer side of the fast-connect steel plate. The connection between the profiled steel concrete column and the concrete beam is completed by means of quick insertion and quick connection. The additionally provided reinforcement component can greatly improve the convenience during the operation of the traditional connection structure on the premise of ensuring the structural strength.

[0007] In a preferred solution, the reinforcement component includes sleeves sleeved at both ends of the high-strength bolts. The sleeves and the threaded pipes are symmetrically distributed in the horizontal direction. Brake members are slidably installed on both sides inside the fast-connect steel plate. A connecting rod is rotatably connected between the sleeve and the brake member. The slidable brake member is in pressing contact with the side wall of the profiled steel.

[0008] By additionally providing a sleeve structure at both ends of the high-strength bolt, the high-strength bolt is screwed in the center to squeeze the sleeve, causing the synchronously moving sleeve to drive the brake member through the connecting rod. While the high-strength bolt laterally fixes the fast-connect steel plate, longitudinal extrusion stress is generated by the brake member, thereby greatly improving the stability of the fast-connect steel plate after fixation.

[0009] In a preferred solution, the transverse reinforcement member includes a number of groups of beam edge sleeves and beam middle sleeves symmetrically welded to both ends of one side of the fast-connect steel plate. Both the beam edge sleeves and the beam middle sleeves are through-hole structures. A truss member is welded to the outside of each group of beam edge sleeves and beam middle sleeves, and several of the truss members are distributed in opposite directions in sequence. A number of groups of second through grooves are penetrated and opened on the side wall of the fast-connect steel plate. When the two fast-connect steel plates are staggered, each group of second through grooves is symmetrically distributed in the horizontal direction with a group of beam edge sleeves and the beam middle sleeves. A beam edge transverse reinforcement is connected by threading between the symmetrically distributed beam edge sleeves and the second through grooves. A beam middle transverse reinforcement is connected through the second through grooves between the symmetrically distributed beam middle sleeves. The beam middle transverse reinforcement penetrates out from the inside of the profiled steel.

[0010] By additionally welding beam-side sleeves and beam-middle sleeves structures to the side of the quick-connect steel plates, the quick connection of the beam-side transverse bars and the beam-middle transverse bars is realized respectively by means of threaded connection and insertion, thereby greatly improving the convenience during the operation of the connection structure of traditional steel reinforced concrete columns and concrete beams. Moreover, while the beam-side transverse bars are screwed into the interior of the beam-side sleeves, by using the symmetric positions of the beam-side sleeves and the second through grooves, the beam-side transverse bars screwed into the beam-side sleeves can be screwed into the interior of the second through grooves together, thereby further improving the stability of the two quick-connect steel plates.

[0011] In a preferred solution, the cross-beam member includes clamping plates symmetrically welded to the side of each of the quick-connect steel plates. A cross steel beam is inserted and engaged inside the clamping plates, and the clamping plates and the cross steel beam are connected by a plurality of reinforcing bolts in a threaded manner.

[0012] By additionally welding a clamping plate structure to the side of the quick-connect steel plates, the quick installation of the cross steel beam is carried out together by using the clamping plates in cooperation with bolt fixation, thereby further improving the convenience during the operation of the connection structure of traditional steel reinforced concrete columns and concrete beams.

[0013] In a preferred solution, channel grooves are provided on the outer sides of each group of the beam-side sleeves, the beam-middle sleeves, and the second through grooves. When the two quick-connect steel plates are inserted and misaligned, several groups of the channel grooves are symmetrically distributed between each other.

[0014] By providing channel grooves on the outer sides of the beam-side sleeves, the beam-middle sleeves, and the second through grooves, and using the insertion and misalignment of the quick-connect steel plates, the channel grooves are butted against each other. While pouring concrete, the concrete is introduced into the connection nodes of the beam-side transverse bars and the beam-middle transverse bars by means of the channel grooves, thereby further improving the stability and structural strength of the beam-side transverse bars and the beam-middle transverse bars after installation.

[0015] As can be seen from the above, a connection structure and construction method of a steel reinforced concrete column and a concrete beam provided by the present invention have the following technical effects.

[0016] Firstly: By providing a connection mechanism, using the connection mechanism to replace the traditional welding fixation method, the outer sides of the steel sections are clamped by two misaligned and inserted quick-connect steel plate structures, and the fixation of the quick-connect steel plates is completed by tightening high-strength bolts. At the same time, beam-side sleeves and beam-middle sleeves structures are additionally welded to the outer sides of the quick-connect steel plates, and the quick connection of the beam-side transverse bars and the beam-middle transverse bars is realized respectively by means of threaded connection and insertion, thereby greatly improving the convenience during the operation of the connection structure of traditional steel reinforced concrete columns and concrete beams.

[0017] Second: By additionally providing a second through-groove structure on the outer side of the quick-connect steel plate, while the transverse bars at the beam edge are screwed into the inner part of the sleeve at the beam edge by threads, the transverse bars at the beam edge screwed into the sleeve at the beam edge can be screwed into the inner part of the second through-groove together by utilizing the symmetric positions of the sleeve at the beam edge and the second through-groove, thereby further improving the stability of the two quick-connect steel plates. Channels are provided on the outer sides of the sleeve at the beam edge, the sleeve in the middle of the beam, and the second through-groove. By the insertion and dislocation of the quick-connect steel plates, the channels are butted pairwise. While filling with concrete, the channels lead the concrete to the connection nodes of the transverse bars at the beam edge and the transverse bars in the middle of the beam, thereby further improving the stability and structural strength of the transverse bars at the beam edge and the transverse bars in the middle of the beam after installation.

[0018] Third: By additionally providing a kit structure at both ends of the high-strength bolt, the kit is extruded by the centering and tightening of the high-strength bolt, so that the synchronously moving kit drives the braking part through the connecting rod. While the high-strength bolt fixes the quick-connect steel plate transversely, longitudinal extrusion stress is generated by the braking part, thereby greatly improving the stability of the quick-connect steel plate after fixation.

[0019] Fourth: Truss members are additionally welded between pairs of the sleeves at the beam edge and the sleeves in the middle of the beam, and several truss members are distributed in opposite directions in sequence. By utilizing the truss members to increase the stress after connection, in extreme weather such as earthquakes, the truss members can reduce the shear force received at the connection of the transverse bars at the beam edge and the transverse bars in the middle of the beam by using the stress, thereby greatly improving the stability and structural strength of the connection of the transverse bars at the beam edge and the transverse bars in the middle of the beam.

Specific implementation manner

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] A connection structure and construction method for a steel reinforced concrete column and a concrete beam disclosed by the present invention are mainly applied to the scenario of connecting a steel reinforced concrete column and a concrete beam.

[0032] Referring to Figures 1 to 9 , a connection structure for a steel reinforced concrete column and a concrete beam includes a section steel 1 fixed on a foundation. A connection mechanism 2 is arranged outside the section steel 1. The connection mechanism 2 includes two quick-connection steel plates 201 that are staggeredly inserted and clamped outside the section steel 1. A threaded pipe 202 is welded to the inner side of each quick-connection steel plate 201. A first through groove 203 is penetrated through the inner side of the section steel 1. The threaded pipe 202 and the first through groove 203 are symmetrically distributed and penetrated by a high-strength bolt 204. The two quick-connection steel plates 201 are fixed outside the section steel 1 through the high-strength bolt 204; A reinforcement component 3 is arranged outside the high-strength bolt 204; A transverse reinforcement member 4 is arranged outside each quick-connection steel plate 201; A cross-beam member 5 is also arranged outside each quick-connection steel plate 201; Through the cooperation of the connection mechanism 2 and the reinforcement component 3, it is stably connected outside the section steel 1, saving welding while realizing the quick connection of the transverse reinforcement member 4 and the cross-beam member 5.

[0033] In this embodiment: The worker hoists the profiled steel 1 to the top of the foundation by a crane. According to the construction plan, the profiled steel 1 is fixed to the top of the foundation by means of embedding, riveting, connectors, bolts, etc. Then, two quick-connect steel plates 201 are inserted in a staggered manner and clamped at a preset height outside the profiled steel 1. Then, two high-strength bolts 204 are respectively passed through the threaded pipe 202 and the first through groove 203, and the high-strength bolts 204 are tightened by an electric wrench to fix the quick-connect steel plates 201. During the process of tightening the high-strength bolts 204, the reinforcement assembly 3 is squeezed to generate stress on the inner side of the profiled steel 1, thereby improving the stability of the quick-connect steel plates 201. Then, the worker quickly connects the transverse rib member 4 to the outside of the quick-connect steel plates 201 by means of threaded connection and through connection; the cross beam member 5 is quickly installed on the outside of the quick-connect steel plates 201 by means of threaded connection. After the worker checks that the entire structure is connected correctly, the entire frame is sealed with plates and concrete slurry is poured.

[0034] Among them, several longitudinal ribs 6 are evenly distributed in a rectangular shape on the outside of the profiled steel 1. The longitudinal ribs 6 and the profiled steel 1 are embedded into the foundation together to improve the structural strength after the concrete solidifies.

[0035] Furthermore, a damping gasket 2041 is slidably sleeved on the outside of the high-strength bolt 204. The damping gasket 2041 is in extrusion contact with the kit 301 to improve the structural strength after the high-strength bolt 204 is tightened by increasing the friction force.

[0036] Refer to Figures 6 to 9 , in a preferred embodiment, the reinforcement assembly 3 includes kits 301 sleeved at both ends of the high-strength bolt 204. The kits 301 and the threaded pipe 202 are symmetrically distributed in the horizontal direction. Braking members 302 are slidably installed on both sides inside the quick-connect steel plates 201. A connecting rod 303 is rotatably connected between the kits 301 and the braking members 302. The sliding braking members 302 are in extrusion contact with the side wall of the profiled steel 1.

[0037] During the process of the worker tightening the high-strength bolt 204, the high-strength bolt 204 will exert extrusion on the kit 301, causing the kit 301 to move centrally. While the kit 301 is moving, it will push the braking member 302 through the connecting rod 303, thereby causing the braking member 302 to be extruded against the inner side of the profiled steel 1, generating stress to improve the stability of the quick-connect steel plates 201.

[0038] Refer to Figures 1 to 8, in a preferred embodiment, the transverse rib member 4 includes a plurality of groups of beam-side sleeves 401 and beam-middle sleeves 402 symmetrically welded to both ends of one side of the quick-connect steel plate 201. Both the beam-side sleeves 401 and the beam-middle sleeves 402 are through-hole structures. A truss member 403 is welded to the outside of each group of beam-side sleeves 401 and beam-middle sleeves 402, and several truss members 403 are distributed in opposite directions in sequence. A plurality of groups of second through-grooves 405 are formed through the side wall of the quick-connect steel plate 201. When the two quick-connect steel plates 201 are distributed in a staggered manner, each group of second through-grooves 405 is symmetrically distributed horizontally with a group of beam-side sleeves 401 and beam-middle sleeves 402. A beam-side transverse rib 404 is connected to the inside of the symmetrically distributed beam-side sleeve 401 and the second through-groove 405 by means of a thread, and a beam-middle transverse rib 406 is connected through the inside of the symmetrically distributed beam-middle sleeve 402 and the second through-groove 405. The beam-middle transverse rib 406 penetrates out from the inside of the profiled steel 1.

[0039] During the process of the worker inserting the quick-connect steel plates 201 in a staggered manner, the beam-side sleeves 401 and the second through-grooves 405, and the beam-middle sleeves 402 and the second through-grooves 405 on the two quick-connect steel plates 201 will be aligned in pairs in sequence. After the installation of the quick-connect steel plates 201 is completed, the worker holds the beam-side transverse rib 404 and rotates the threaded end of the beam-side transverse rib 404 into the inside of the beam-side sleeve 401. As the worker continuously rotates the beam-side transverse rib 404, the threaded end of the beam-side transverse rib 404 will gradually spin out from the inside of the beam-side sleeve 401 and spin into the aligned second through-groove 405 inside, thereby connecting the two quick-connect steel plates 201 together. Then, the worker holds the beam-middle transverse rib 406 and directly passes the beam-middle transverse rib 406 through the beam-middle sleeve 402 and the aligned second through-groove 405, thus completing the installation of the beam-side transverse rib 404 and the beam-middle transverse rib 406.

[0040] Among them, a third through-groove 407 is formed through the inside of the profiled steel 1, and the beam-middle transverse rib 406 penetrates out from the inside of the third through-groove 407. A channel groove 408 is formed on the outside of each group of beam-side sleeves 401, beam-middle sleeves 402, and second through-grooves 405. When the two quick-connect steel plates 201 are inserted in a staggered manner, several groups of channel grooves 408 are symmetrically distributed between each other. When the entire framework is filled with concrete, the concrete will flow into the inside of the channel grooves 408, thereby further improving the structural strength after the overall connection.

[0041] Furthermore, a plurality of binding ribs 409 are bundled outside several beam-side transverse ribs 404 and beam-middle transverse ribs 406 on the same side, which is used to improve the structural strength of the beam-side transverse ribs 404 and beam-middle transverse ribs 406 after pouring concrete.

[0042] Refer to Figure 1 、 Figures 3 to 7, in a preferred embodiment, the crossbeam member 5 includes clamping plates 501 symmetrically welded to the sides of each quick-connect steel plate 201. A crossbeam 502 is inserted and engaged inside the clamping plates 501, and the clamping plates 501 and the crossbeam 502 are threadedly connected by a plurality of reinforcing bolts 503.

[0043] After the installation of the transverse bars 404 at the beam edge and the transverse bars 406 in the beam is completed, at this time, the worker holds the crossbeam 502 by hand, engages the crossbeam 502 into the inside of the clamping plates 501, then holds the reinforcing bolts 503 by hand, passes a plurality of reinforcing bolts 503 through the clamping plates 501 in sequence, and tightens them on the outside of the clamping plates 501 and the crossbeam 502 to complete the fixation of the crossbeam 502.

[0044] The work process is as follows: During use, workers use a crane to hoist the profiled steel 1 to the top of the foundation. According to the construction plan, the profiled steel 1 is fixed to the top of the foundation by means of embedding, riveting, connectors, bolts, etc. During this process, the longitudinal reinforcement 6 and the profiled steel 1 are embedded into the interior of the foundation together. Then, two quick-connect steel plates 201 are inserted in a staggered manner and clamped at a preset height outside the profiled steel 1. Then, two high-strength bolts 204 are respectively passed through the threaded pipe 202 and the first through groove 203, and the high-strength bolts 204 are tightened by an electric wrench to fix the quick-connect steel plates 201. During the process of tightening the high-strength bolts 204, the high-strength bolts 204 will exert extrusion on the kit 301, causing the kit 301 to move centrally. While the kit 301 is moving, it will push the braking member 302 through the connecting rod 303, so that the braking member 302 is extruded against the inner side of the profiled steel 1, generating stress to improve the stability of the quick-connect steel plates 201. During the process of the workers inserting the quick-connect steel plates 201 in a staggered manner, the beam-side sleeves 401 and the second through grooves 405, and the beam-middle sleeves 402 and the second through grooves 405 on the two quick-connect steel plates 201 will be aligned in pairs in sequence. After completing the installation of the quick-connect steel plates 201, the worker holds the beam-side horizontal reinforcement 404 and rotates the threaded end of the beam-side horizontal reinforcement 404 into the interior of the beam-side sleeve 401. As the worker continuously rotates the beam-side horizontal reinforcement 404, the threaded end of the beam-side horizontal reinforcement 404 will gradually screw out of the interior of the beam-side sleeve 401 and screw into the aligned second through groove 405, thereby connecting the two quick-connect steel plates 201 together. Then, the worker holds the beam-middle horizontal reinforcement 406 and directly passes the beam-middle horizontal reinforcement 406 through the beam-middle sleeve 402 and the aligned second through groove 405, thereby completing the installation of the beam-side horizontal reinforcement 404 and the beam-middle horizontal reinforcement 406. After completing the installation of the beam-side horizontal reinforcement 404 and the beam-middle horizontal reinforcement 406, at this time, the worker holds the cross steel beam 502 and clamps the cross steel beam 502 into the interior of the clamping plate 501. Then, the worker holds the reinforcement bolts 503 and passes several reinforcement bolts 503 through the clamping plate 501 in sequence and tightens them on the outside of the clamping plate 501 and the cross steel beam 502 to complete the fixation of the cross steel beam 502. After that, the worker holds the tying reinforcement 409 and ties several tying reinforcements 409 on the outside of the beam-side horizontal reinforcement 404 and the beam-middle horizontal reinforcement 406 in sequence. After the worker checks that the entire structure is connected correctly, the entire frame is sealed with plates and concrete slurry is poured.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
