Description

Technical Field

[0001] The present 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 columns (SRC columns) and concrete beams (RC beams) is a hybrid node structure, mainly used to reliably connect reinforced concrete columns containing steel sections to ordinary reinforced concrete beams in construction or bridge engineering. It must meet requirements such as 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 the welders. While the operation is cumbersome, it is easy to produce defects such as air holes, 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 present invention discloses a connection structure and construction method for a steel reinforced concrete column and a concrete beam, aiming to solve the technical problems of the existing method of welding and fixing steel reinforced concrete columns and concrete beams, in which 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 air holes, slag inclusions and uneven welds are easily generated.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A steel reinforced concrete column and concrete beam connection structure, comprising a steel section fixed to a foundation, a connection mechanism provided on the outer side of the steel section, the connection mechanism comprising two quick-connect steel plates staggered and inserted and engaged with the outer side of the steel section, a threaded tube welded to the inner side of each quick-connect steel plate, a first through-slot penetrated through the inner side of the steel section, the threaded tube and the first through-slot being symmetrically distributed and penetrated by high-strength bolts, and the two quick-connect steel plates are fixed to the outer side of the steel section by the high-strength bolts;

[0007] A reinforcement component is provided on the outer side of the high-strength bolt;

[0008] A transverse reinforcement member is provided on the outer side of each of the quick-connect steel plates;

[0009] A crossbeam member is also provided on the outer side of each quick-connect steel plate;

[0010] The connection mechanism cooperates with the reinforcement assembly to stably connect to the outer side of the steel section, thereby eliminating welding and achieving a quick connection between the cross rib member and the cross beam member.

[0011] By providing a connecting mechanism, the connecting mechanism is used to replace the traditional welding fixing method, and two staggered and interlaced quick-connect steel plate structures are clamped on the outside of the steel section. The quick-connect steel plate is fixed by tightening the high-strength bolts. At the same time, cross reinforcement members and cross beam members are additionally provided on the outside of the quick-connect steel plate. The connection between the steel-concrete column and the concrete beam is completed by quick insertion and quick connection. The additional reinforcement components can greatly improve the convenience of operating the traditional connection structure while ensuring the structural strength.

[0012] In a preferred embodiment, the reinforcement assembly includes a kit that is sleeved on both ends of the high-strength bolt, the kit and the threaded tube are symmetrically distributed in the horizontal direction, brake parts are slidably installed on both sides of the interior of the quick-connect steel plate, and a connecting rod is rotatably connected between the kit and the brake parts, and the sliding brake parts are in extrusion contact with the side walls of the steel section.

[0013] By additionally providing a kit structure at both ends of the high-strength bolt, the kit is squeezed by tightening the high-strength bolt in the center, so that the synchronously moving kit drives the brake piece through the connecting rod. While the high-strength bolt fixes the quick-connect steel plate horizontally, the brake piece is used to generate longitudinal extrusion stress, thereby greatly improving the stability of the quick-connect steel plate after fixation.

[0014] In a preferred embodiment, the transverse reinforcement member includes several groups of beam side sleeves and beam middle sleeves symmetrically welded to the two ends of one side of the quick-connect steel plate, the beam side sleeves and the beam middle sleeves are both through-opening structures, and truss members are welded to the outside of each group of the beam side sleeves and the beam middle sleeves, and several of the truss members are distributed in opposite order. The side wall of the quick-connect steel plate is penetrated by a plurality of groups of second through grooves. When the two quick-connect steel plates are staggered, each group of the second through grooves is symmetrically distributed with a group of the beam side sleeves and the beam middle sleeves in the horizontal direction. The symmetrically distributed beam side sleeves and the second through grooves are internally connected with beam side transverse reinforcements through threads, and the symmetrically distributed beam middle sleeves and the second through grooves are internally connected with beam middle transverse reinforcements, and the beam middle transverse reinforcements pass through the interior of the steel section.

[0015] By additionally welding beam side sleeves and beam middle sleeve structures on the side of the quick-connect steel plate, the beam side transverse reinforcement and beam middle transverse reinforcement are quickly connected respectively by means of threaded connection and plug-in connection, thereby greatly improving the convenience of operation of the traditional steel-concrete column and concrete beam connection structure. While the beam side transverse reinforcement is screwed into the beam side sleeve by thread, the symmetrical position of the beam side sleeve and the second through groove allows the beam side transverse reinforcement screwed into the beam side sleeve to be screwed into the interior of the second through groove at the same time, thereby further improving the stability of the two quick-connect steel plates.

[0016] In a preferred embodiment, the crossbeam component includes a clamping plate symmetrically welded to the side of each quick-connect steel plate, a cross steel beam is plugged into the interior of the clamping plate, and the clamping plate and the cross steel beam are threadedly connected by a plurality of reinforcing bolts.

[0017] By additionally welding a clamping plate structure on the side of the quick-connect steel plate, the horizontal steel beam can be quickly installed by using the clamping plate in combination with bolts, thereby further improving the convenience of operating the traditional steel-concrete column and concrete beam connection structure.

[0018] In a preferred solution, each group of the beam side sleeves, the beam middle sleeves and the outer side of the second through groove are provided with channel grooves. When the two quick-connect steel plates are interlaced and misaligned, several groups of the channel grooves are symmetrically distributed between each other.

[0019] By opening channel grooves on the outer sides of the beam side sleeves, the beam middle sleeves and the second through grooves, and using the interlaced and staggered quick-connect steel plates to connect the channel grooves in pairs, while pouring concrete, the channel grooves are used to guide the concrete into the connection nodes of the beam side transverse reinforcement and the beam middle transverse reinforcement, thereby further improving the stability and structural strength of the beam side transverse reinforcement and the beam middle transverse reinforcement after installation.

[0020] From the above, it can be seen that the connection structure of the steel reinforced concrete column and the concrete beam and the construction method provided by the present invention have the following technical effects.

[0021] First: by setting up a connection mechanism, the connection mechanism is used to replace the traditional welding fixing method. Two staggered and interlaced quick-connect steel plate structures are clamped on the outside of the steel section, and the high-strength bolts are tightened to complete the fixation of the quick-connect steel plate. At the same time, the outside of the quick-connect steel plate is additionally welded with a beam side sleeve and a beam middle sleeve structure. The beam side transverse reinforcement and the beam middle transverse reinforcement are quickly connected respectively by means of threaded connection and plug-in connection, thereby greatly improving the convenience of operating the traditional steel-concrete column and concrete beam connection structure.

[0022] Secondly, by additionally providing a second through-groove structure on the outer side of the quick-connect steel plate, the beam side transverse reinforcement is screwed into the interior of the beam side sleeve by means of threads. At the same time, the beam side transverse reinforcement screwed into the beam side sleeve can be screwed into the interior of the second through-groove by means of the symmetrical position of the beam side sleeve and the second through-groove, thereby further improving the stability of the two quick-connect steel plates. Channel grooves are provided on the outer sides of the beam side sleeve, the beam middle sleeve and the second through-groove. By means of the interlaced and dislocated quick-connect steel plates, the channel grooves are connected in pairs. When concrete is poured, the channel grooves guide the concrete into the connection nodes of the beam side transverse reinforcement and the beam middle transverse reinforcement, thereby further improving the stability and structural strength of the beam side transverse reinforcement and the beam middle transverse reinforcement after installation.

[0023] Third: By additionally providing a kit structure at both ends of the high-strength bolt, the kit is squeezed by tightening the high-strength bolt in the center, so that the synchronously moving kit drives the brake part through the connecting rod. While the high-strength bolt fixes the quick-connect steel plate horizontally, the brake part is used to generate longitudinal extrusion stress, thereby greatly improving the stability of the quick-connect steel plate after fixation.

[0024] Fourthly, truss members are welded between several groups of beam side sleeves and beam middle sleeves, and several truss members are distributed in opposite directions. The truss members are used to increase the stress after the connection. In extreme weather conditions such as earthquakes, the truss members can use the stress to reduce the shear force at the connection between the beam side transverse reinforcement and the beam middle transverse reinforcement, thereby greatly improving the stability and structural strength after the connection between the beam side transverse reinforcement and the beam middle transverse reinforcement.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] The present invention discloses a connection structure of a steel reinforced concrete column and a concrete beam and a construction method thereof, which are mainly used in scenarios where a steel reinforced concrete column and a concrete beam are connected.

[0037] Reference Figures 1 to 9 A connection structure of a steel reinforced concrete column and a concrete beam includes a steel section 1 fixed to a foundation, a connection mechanism 2 being provided on the outer side of the steel section 1, the connection mechanism 2 including two quick-connect steel plates 201 that are staggered, inserted, and engaged with the outer side of the steel section 1, a threaded tube 202 being welded to the inner side of each quick-connect steel plate 201, a first through-groove 203 being formed through the inner side of the steel section 1, the threaded tube 202 and the first through-groove 203 being symmetrically distributed, and high-strength bolts 204 being passed through, and the two quick-connect steel plates 201 being fixed to the outer side of the steel section 1 by the high-strength bolts 204;

[0038] A reinforcement component 3 is provided on the outside of the high-strength bolt 204;

[0039] A transverse reinforcement member 4 is provided on the outer side of each quick-connect steel plate 201;

[0040] A crossbeam member 5 is also provided on the outside of each quick-connect steel plate 201;

[0041] The connection mechanism 2 cooperates with the reinforcement component 3 to stably connect to the outer side of the steel section 1, eliminating welding and achieving a quick connection of the cross rib member 4 and the cross beam member 5.

[0042] In this embodiment: workers use a crane to lift the steel section 1 to the top of the foundation, and according to the construction plan, the steel section 1 is fixed to the top of the foundation by pre-embedding, riveting, connecting parts, bolts, etc., and then the two quick-connect steel plates 201 are inserted and dislocated, and locked at a preset height on the outside of the steel section 1, and then two high-strength bolts 204 are passed through the threaded tube 202 and the first through groove 203 respectively, and the high-strength bolts 204 are tightened with an electric wrench to fix the quick-connect steel plate 201; and in the process of tightening the high-strength bolts 204, the reinforcement component 3 is squeezed and stress is generated on the inner side of the steel section 1, thereby improving the stability of the quick-connect steel plate 201, and then the workers use threaded connection and through-connection to quickly connect the crossbar member 4 to the outside of the quick-connect steel plate 201; and use threaded connection to quickly install the crossbeam member 5 to the outside of the quick-connect steel plate 201; after checking that the entire structure is connected correctly, the workers seal the entire frame and pour concrete slurry.

[0043] Among them, the outer side of the steel section 1 is rectangular and evenly distributed with a number of longitudinal bars 6. The longitudinal bars 6 and the steel section 1 are pre-buried into the interior of the foundation to improve the structural strength of the concrete after solidification.

[0044] Furthermore, a damping washer 2041 is slidably sleeved on the outer side of the high-strength bolt 204 , and the damping washer 2041 is in squeeze contact with the sleeve 301 , thereby increasing friction to improve the structural strength of the high-strength bolt 204 after being tightened.

[0045] Reference Figures 6 to 9 In a preferred embodiment, the reinforcement component 3 includes a kit 301 that is sleeved on both ends of the high-strength bolt 204. The kit 301 and the threaded tube 202 are symmetrically distributed in the horizontal direction. Stoppers 302 are slidably installed on both sides of the inside of the quick-connect steel plate 201. A connecting rod 303 is rotatably connected between the kit 301 and the stopper 302. The sliding stopper 302 is in extrusion contact with the side wall of the steel section 1.

[0046] When workers tighten the high-strength bolts 204, the high-strength bolts 204 will squeeze the kit 301, causing the kit 301 to move in the center. While the kit 301 moves, it will push the stopper 302 through the connecting rod 303, causing the stopper 302 to be squeezed on the inner side of the steel section 1, generating stress to improve the stability of the quick-connect steel plate 201.

[0047] Reference Figures 1 to 8In a preferred embodiment, the transverse reinforcement member 4 includes several 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. The beam side sleeves 401 and the beam middle sleeves 402 are both through-opening 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 order. Several groups of second through grooves 405 are opened through the side wall of the quick-connect steel plate 201. When the two quick-connect steel plates 201 are staggered, each group of second through grooves 405 is symmetrically distributed with a group of beam side sleeves 401 and beam middle sleeves 402 in the horizontal direction. The symmetrically distributed beam side sleeves 401 and the second through grooves 405 are internally connected to the beam side transverse reinforcement 404 by threads, and the symmetrically distributed beam middle sleeves 402 and the second through grooves 405 are internally connected to the beam middle transverse reinforcement 406. The beam middle transverse reinforcement 406 passes through the interior of the steel section 1.

[0048] During the process of workers staggering and inserting the quick-connect steel plates 201, 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 workers hold the beam side transverse reinforcement 404 and rotate the threaded end of the beam side transverse reinforcement 404 into the interior of the beam side sleeves 401. As the workers continue to rotate the beam side transverse reinforcement 404, the threaded end of the beam side transverse reinforcement 404 will gradually be screwed out from the interior of the beam side sleeves 401 and screwed into the aligned second through grooves 405, thereby connecting the two quick-connect steel plates 201 together. After that, the workers hold the beam middle transverse reinforcement 406 and pass the beam middle transverse reinforcement 406 directly through the beam middle sleeves 402 and the aligned second through grooves 405, thereby completing the installation of the beam side transverse reinforcement 404 and the beam middle transverse reinforcement 406.

[0049] Among them, a third through groove 407 is opened through the interior of the steel section 1, and the transverse reinforcement 406 in the beam passes through the inside of the third through groove 407, and each group of beam side sleeves 401, beam sleeves 402 and the outer side of the second through groove 405 are opened with a channel groove 408. When the two quick-connect steel plates 201 are interlaced and misplaced, several groups of channel grooves 408 are symmetrically distributed between each other. When the entire frame is filled with concrete, the concrete will flow into the interior of the channel groove 408, thereby further improving the structural strength after the overall connection.

[0050] Furthermore, a plurality of binding bars 409 are bundled outside the plurality of beam side transverse bars 404 and beam middle transverse bars 406 on the same side, so as to improve the structural strength of the beam side transverse bars 404 and beam middle transverse bars 406 after pouring concrete.

[0051] Reference Figure 1 、 Figures 3 to 7In a preferred embodiment, the crossbeam member 5 includes a clamping plate 501 symmetrically welded to the side of each quick-connect steel plate 201, and a cross steel beam 502 is plugged into and engaged with the interior of the clamping plate 501, and the clamping plate 501 and the cross steel beam 502 are threadedly connected by a plurality of reinforcing bolts 503.

[0052] After completing the installation of the beam side transverse reinforcement 404 and the beam middle transverse reinforcement 406, the worker now holds the horizontal steel beam 502 and snaps the horizontal steel beam 502 into the inside of the clamping plate 501. Then, he holds the reinforcing bolts 503 and passes several reinforcing bolts 503 through the clamping plate 501 in turn, and tightens them to the outside of the clamping plate 501 and the horizontal steel beam 502 to complete the fixation of the horizontal steel beam 502.

[0053] The workflow is as follows:

[0054] During use, workers use a crane to lift the steel section 1 to the top of the foundation. According to the construction plan, the steel section 1 is fixed to the top of the foundation by means of pre-embedding, riveting, connecting pieces, bolts, etc. In this process, the longitudinal reinforcement 6 and the steel section 1 are pre-embedded into the interior of the foundation together, and then the two quick-connect steel plates 201 are inserted and dislocated, and locked at a preset height on the outside of the steel section 1. Then, two high-strength bolts 204 are passed through the threaded tube 202 and the first through groove 203 respectively, and the high-strength bolts 204 are tightened with an electric wrench to fix the quick-connect steel plate 201; and in the process of tightening the high-strength bolts 204, The high-strength bolts 204 will squeeze the kit 301, causing the kit 301 to move in the center. While the kit 301 moves, it will push the stopper 302 through the connecting rod 303, causing the stopper 302 to be squeezed on the inner side of the steel section 1, generating stress to improve the stability of the quick-connect steel plate 201. During the process of workers displacing and inserting the quick-connect steel plates 201, 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 turn. After completing the installation of the quick-connect steel plates 201, the workers hold the beam side transverse reinforcement 404 , rotate the threaded end of the beam side transverse reinforcement 404 into the interior of the beam side sleeve 401. As the worker continues to rotate the beam side transverse reinforcement 404, the threaded end of the beam side transverse reinforcement 404 will gradually be screwed out from the interior of the beam side sleeve 401 and screwed into the aligned second through groove 405, thereby connecting the two quick-connect steel plates 201 together. After that, the worker holds the beam middle transverse reinforcement 406 and passes the beam middle transverse reinforcement 406 directly through the beam middle sleeve 402 and the aligned second through groove 405, thereby completing the installation of the beam side transverse reinforcement 404 and the beam middle transverse reinforcement 406. 4 and the installation of the transverse reinforcement 406 in the beam, the worker now holds the horizontal steel beam 502 and snaps the horizontal steel beam 502 into the inside of the clamping plate 501, then holds the reinforcing bolts 503 and passes several reinforcing bolts 503 through the clamping plate 501 in turn, and tightens them to the outside of the clamping plate 501 and the transverse steel beam 502, completing the fixation of the transverse steel beam 502. After that, the worker holds the binding reinforcement 409 and binds several binding reinforcements 409 to the outside of the beam side transverse reinforcement 404 and the beam middle transverse reinforcement 406 in turn. After that, the worker checks that the entire structure is connected correctly, seals the entire frame and pours concrete slurry.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
