Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel-concrete beam and column technology, specifically a novel steel-concrete beam and column connection structure. Background Technology
[0002] Steel-concrete composite (SRC) structures combine the high toughness of steel with the compressive strength of concrete, and are widely used in high-rise buildings, large-span factories, and buildings in seismic fortification zones. Beam-column connections, as the core hubs for structural force transmission, directly determine the overall structure's load-bearing capacity, seismic ductility, and construction efficiency, making them a crucial aspect of SRC structure design and construction.
[0003] Existing steel-concrete composite beam-column connection methods mainly include welding, traditional bolting, and stud-concrete bonding. However, these methods have several shortcomings in practical applications: Firstly, they are inconvenient to construct: traditional welding requires on-site open flame work, which places high demands on the construction environment and the skills of the operators, and is easily affected by weather, leading to delays in the construction period; although bolting eliminates the need for welding, it requires strict precision in component positioning. Once there are errors in manufacturing or installation, it is difficult to adjust on-site, requiring additional cutting or welding, increasing construction costs. Secondly, they lack adaptability and adjustment capabilities: existing nodes are mostly rigid fixed structures, lacking effective error compensation mechanisms, and cannot adapt to installation deviations in steel beams and concrete columns. When there are slight deviations in component dimensions, it is easy to cause uneven stress on the node, which can lead to crack development and affect structural durability. Thirdly, the reliability and seismic performance of the connection are limited: some nodes rely on a single force transmission path (such as force transmission only through bolts or bonding), which can easily lead to local stress concentration under seismic action, causing premature failure of the node; at the same time, the traditional fixing methods of nodes lack elastic adjustment space and have insufficient seismic ductility, making it difficult to meet the seismic design requirements of high-intensity earthquake zones.
[0004] Therefore, this utility model provides a novel steel-concrete beam-column connection structure. Utility Model Content
[0005] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background art, a novel steel-concrete beam-column connection structure is proposed.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A novel steel-concrete beam-column connection structure of this utility model includes a concrete column; steel beams are movably connected to both sides of the top of the concrete column; a docking assembly is provided on the top of the concrete column; a plug-in assembly is provided on the top of the docking assembly; support mechanisms are provided on both sides of the cross-shaped plug; an adjustment mechanism is provided on the side of the support mechanism away from the cross-shaped plug; a connecting mechanism is provided on the side of the adjustment mechanism away from the support mechanism; a positioning mechanism is provided on the top of the support mechanism; the docking assembly includes a fixing block and a cross groove; the fixing block is fixedly installed on the top of the concrete column; the top of the fixing block has a cross groove; the cooperation of the fixing block and the cross groove allows the plug-in assembly to be quickly inserted into the fixing block, thereby enabling deployment and installation to be completed in a short time, shortening the installation time and accelerating the project progress.
[0007] Preferably, the plug-in assembly includes a cross-shaped plug and a first bolt. The cross-shaped plug is movably inserted into the inner wall of the fixing block through the opening of the cross groove. The first bolt passes through the cross-shaped plug to the inner wall of the cross groove. The first bolt is threadedly connected to the cross-shaped plug and the cross groove respectively. In this scheme, the cooperation of the cross-shaped plug and the first bolt can achieve stable support for the support mechanism through quick insertion and fixation with the fixing block, so that it has sufficient load-bearing and seismic resistance during use.
[0008] Preferably, the support mechanism includes a connecting block, a fixing plate, and a support plate. The connecting block is fixedly installed on both sides of the top of the cross-shaped insert. The side of the connecting block away from the cross-shaped insert is welded to the fixing plate. The fixing plate is welded to the cross-shaped insert. The bottom of the fixing plate away from the connecting block is fixedly installed to the support plate. In this scheme, the coordinated use of the connecting block, the fixing plate, and the support plate can provide stable support and guidance for the adjustment mechanism, so that it will not shake during adjustment, and ensure that the stability and strength of the structure will not be reduced.
[0009] Preferably, the adjusting mechanism includes a T-slot, a T-block, a friction block, and a connecting plate. The T-slot is located in the middle of the fixed plate on the side away from the connecting block. The T-block is slidably mounted on the inner wall of the fixed plate through the T-slot. The side of the T-block away from the fixed plate is fixedly mounted to the friction block, and the side of the friction block away from the T-block is fixedly mounted to the connecting plate. In this design, the cooperation of the T-slot and the T-block enables the steel beam to maintain sufficient stability during adjustment, while also preventing the friction block from dislodging from the designated position. The cooperation of the friction block and the connecting plate provides stable support for the connecting mechanism and also generates friction with the clamping block.
[0010] Preferably, the connecting mechanism includes an L-shaped plate, a reinforcing rib, a slot, an insert, and a second bolt. The L-shaped plate is fixedly installed on both sides of the connecting plate away from the friction block. The two sets of L-shaped plates are fixedly installed on opposite sides of the reinforcing rib. The insert is fixedly installed in the middle of the connecting plate on the side away from the friction block. The slot is opened on the side of the steel beam near the insert. The steel beam is movably inserted into the surface of the insert through the slot. The steel beam is located on the inner wall of the L-shaped plate and is slidably connected to the L-shaped plate. The second bolt passes through the L-shaped plate to the inner wall of the steel beam and is threadedly connected to both the L-shaped plate and the steel beam. In this scheme, the combined use of the L-shaped plate, reinforcing rib, slot, insert, and second bolt allows the steel beam to be inserted into the L-shaped plate in a short time and fixed. At the same time, the connection of the two sets of L-shaped plates and the reinforcing rib through the second bolt provides stable support for the steel beam, preventing it from shifting. Meanwhile, the positioning of the insert prevents the steel beam from tilting.
[0011] Preferably, the positioning mechanism includes a rectangular groove, a T-shaped movable rod, a clamping block, and a third bolt. The rectangular groove is located on the top of the fixed plate on the side away from the connecting block. The T-shaped movable rod is slidably installed on the inner wall of the fixed plate through the rectangular groove. The side of the T-shaped movable rod away from the fixed plate is fixedly installed with the clamping block. The two sides of the top of the T-shaped movable rod are threadedly connected to the top of the fixed plate by the third bolt. In this scheme, the cooperation of the rectangular groove, the T-shaped movable rod, the clamping block, and the third bolt allows the T-shaped movable rod to rise and fall by tightening and loosening the third bolt. When the T-shaped movable rod falls, it can drive the clamping block to firmly bite the friction block downwards, so that the friction block will not slip again after installation.
[0012] The beneficial effects of this utility model are as follows: 1. The novel steel-concrete beam-column connection structure of this utility model, through the setting of a fixing block, a cross groove, a cross insert, and a first bolt, allows the fixing block and the cross groove to work together to enable the insertion component to be quickly inserted into the fixing block, thereby completing deployment and installation in a short time, shortening the installation time and accelerating the project progress. The cross insert and the first bolt work together to achieve stable support for the support mechanism through quick insertion and fixation with the fixing block, giving it sufficient load-bearing and seismic resistance during use.
[0013] 2. The novel steel-concrete beam-column connection structure of this utility model, through the arrangement of connecting blocks, fixing plates, supporting plates, T-slots, T-blocks, friction blocks, and connecting plates, enables the connecting blocks, fixing plates, and supporting plates to provide stable support and guidance for the adjustment mechanism, preventing wobbling during adjustment and ensuring that the stability and strength of the structure are not reduced. The cooperation of the T-slots and T-blocks enables the steel beam to maintain sufficient stability during adjustment, while also preventing the friction blocks from dislodging from the designated position. The cooperation of the friction blocks and connecting plates provides stable support for the connection mechanism and also generates friction with the clamping blocks. Attached Figure Description

The cross-shaped insert 41 and the first bolt 42 are connected. The cross-shaped insert 41 is movably inserted into the inner wall of the fixed block 31 through the opening of the cross groove 32. The first bolt 42 passes through the cross-shaped insert 41 to the inner wall of the cross groove 32 and is threadedly connected to the cross-shaped insert 41 and the cross groove 32 respectively. The support mechanism 5 includes a connecting block 51, a fixed plate 52 and a support plate 53. The connecting block 51 is fixedly installed on both sides of the top of the cross-shaped insert 41.

The adjustment mechanism 6 includes a T-slot 61, a T-block 62, a friction block 63 and a connecting plate 64. A T-slot 61 is formed in the middle of the fixed plate 52 on the side away from the connecting block 51. The T-block 62 is slidably installed on the inner wall of the fixed plate 52 through the T-slot 61. The side of the T-block 62 away from the fixed plate 52 is fixedly installed with the friction block 63. The side of the friction block 63 away from the T-block 62 is fixedly installed with the connecting plate 64. The connecting mechanism 7 includes an L-shaped plate 71, a reinforcing rib 72, a slot 73, an insert block 74, and a second bolt 75. The L-shaped plate 71 is fixedly installed on both sides of the connecting plate 64 away from the friction block 63. The sides of the two sets of L-shaped plates 71 that are away from each other are fixedly installed with the reinforcing rib 72. The insert block 74 is fixedly installed in the middle of the side of the connecting plate 64 away from the friction block 63. The slot 73 is formed on the side of the steel beam 2 near the insert block 74. The steel beam 2 is movably inserted into the surface of the insert block 74 through the opening of the slot 73. The steel beam 2 is located on the inner wall of the L-shaped plate 71 and is slidably connected to the L-shaped plate 71. The second bolt 75 passes through the L-shaped plate 71 to the inner wall of the steel beam 2 and is threadedly connected to the L-shaped plate 71 and the steel beam 2 respectively. The positioning mechanism 8 includes a rectangular groove 81, a T-shaped movable rod 82, a clamping block 83 and a third bolt 84. The rectangular groove 81 is opened on the top of the fixed plate 52 on the side away from the connecting block 51. The T-shaped movable rod 82 is slidably installed on the inner wall of the fixed plate 52 through the opening of the rectangular groove 81. The side of the T-shaped movable rod 82 away from the fixed plate 52 is fixedly installed with the clamping block 83. The two sides of the top of the T-shaped movable rod 82 are threadedly connected to the top of the fixed plate 52 through the third bolt 84.
[0020] like Figures 1 to 5 As shown, the cooperation between the fixing block 31 and the cross groove 32 allows the plug-in assembly 4 to be quickly inserted into the fixing block 31, thereby enabling deployment and installation in a short time, shortening the installation time and accelerating the project progress. The cooperation between the cross plug 41 and the first bolt 42 enables stable support for the support mechanism 5 through quick plugging and fixing with the fixing block 31, giving it sufficient load-bearing and seismic resistance during use. The cooperation between the connecting block 51, the fixing plate 52, and the support plate 53 provides stable support and guidance for the adjustment mechanism 6, preventing wobbling during adjustment and ensuring that the stability and strength of the structure are not reduced. The cooperation between the T-slot 61 and the T-block 62 enables the steel beam 2 to maintain sufficient stability during adjustment, while also preventing the friction block 63 from dislodging from the designated position. The friction block 63 and the connecting plate 64... The combined use of the L-shaped plate 71, reinforcing rib 72, slot 73, insert block 74, and second bolt 75 provides stable support for the connecting mechanism 7 and generates friction with the clamping block 83. The combined use of the L-shaped plate 71, reinforcing rib 72, slot 73, insert block 74, and second bolt 75 allows the steel beam 2 to be inserted into the L-shaped plate 71 and fixed in a short time. At the same time, the connection of the two sets of L-shaped plates 71 and reinforcing rib 72 through the second bolt 75 provides stable support for the steel beam 2, preventing it from shifting. Meanwhile, the positioning of the insert block 74 prevents the steel beam 2 from tilting. The combined use of the rectangular groove 81, T-shaped movable rod 82, clamping block 83, and third bolt 84 allows the T-shaped movable rod 82 to rise and fall by tightening and loosening the third bolt 84. When the T-shaped movable rod 82 falls, it can drive the clamping block 83 to firmly bite the friction block 63 downward, so that the friction block 63 will not slip again after installation.
[0021] Working principle: During operation, first align the cross-shaped insert 41 with the cross-shaped groove 32, then insert the cross-shaped insert 41 into the inner wall of the fixing block 31. Next, fix the cross-shaped insert 41 to the inner wall of the fixing block 31 using the first bolt 42. Then, align the slot 73 on one side of the steel beam 2 with the insert 74, and insert the steel beam 2 into the inner wall of the L-shaped plate 71, allowing the steel beam 2 to connect with the L-shaped plate 71. After the steel beam 2 is in place, the user needs to use the second bolt 75 to reinforce the steel beam 2 and the L-shaped plate 71 to prevent loosening. This completes the connection. Due to the simple installation steps and high structural strength, the steel beam 2 can be laid more quickly. To shorten the construction period and improve work efficiency, when the steel beam 2 needs to be fine-tuned after installation, the user should first rotate the third bolt 84 to loosen it. Then, the user can move the T-shaped movable rod 82 upward. When the T-shaped movable rod 82 moves, it will drive the clamping block 83 to rise synchronously. As the clamping block 83 rises, it will no longer bite the friction block 63. At that time, the connecting plate 64 can move slightly laterally through the guidance of the friction block 63 and the T-shaped block 62, thereby achieving the adjustment effect. After the adjustment is completed, the user needs to tighten the two sets of third bolts 84 again to drive the T-shaped movable rod 82 downward so that the clamping block 83 can firmly bite the friction block 63 and prevent it from moving.
[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
