Description
Technical Field
[0001] This utility model relates to the technical field of concrete wall and column support devices, and in particular to a support device for a connection system between steel beams and concrete wall and column. Background Technology
[0002] In steel-concrete composite buildings, the connection and support devices between steel beams and concrete walls and columns are key components for achieving mechanical synergy between different material systems. These devices are widely used in industrial plants, frame-shear wall structures, and high-rise steel structure additions and renovations. Existing structures typically achieve load-bearing and shear resistance by pre-embedded steel plates connected to the ends of steel beams via welding, bolting, or bracket support.
[0003] During the long-term use of a building, periodic micro-vibrations or instantaneous impact forces often occur between steel beams and wall columns due to factors such as foundation settlement, wind loads, equipment vibrations, or occasional earthquakes. If the connection structure is rigidly fixed and lacks buffer energy absorption design, these frequent vibrations will be continuously transmitted to the connection nodes, leading to local stress concentration, which in turn causes bolt loosening, weld fatigue, cracking or deformation of connectors, and in severe cases, reduces the stiffness of the nodes and the overall stability of the structure. Utility Model Content
[0004] Based on this, it is necessary to address the issue that during the long-term use of buildings, periodic micro-vibrations or instantaneous impact forces often occur between steel beams and concrete wall columns due to factors such as foundation settlement, wind loads, equipment vibrations, or occasional earthquakes. If the connection structure is rigidly fixed and lacks a buffer energy absorption design, these frequent vibrations will be continuously transmitted to the connection nodes, leading to local stress concentration, which in turn causes bolt loosening, weld fatigue, cracking or deformation of connectors, and in severe cases, reduces the stiffness of the nodes and the overall stability of the structure. Therefore, a support device for the connection system of steel beams and concrete wall columns is provided, comprising: a support base, on one side of which are two connecting frames located outside the concrete wall column; and a connection buffer mechanism, which is disposed between the concrete wall column and the steel beam to reduce vibration damage when supporting the concrete wall column and the steel beam. The connection buffer mechanism includes a guide frame rotatably mounted on the top of the support base, with a buffer component disposed between the guide frame and the two connecting frames, and a connecting component disposed on one side of each of the two connecting frames.
[0005] The buffer assembly includes a movable column slidably mounted on one side of the guide frame. A sealing groove is provided inside the movable column. A piston rod is fixedly connected to the inner wall of the guide frame. One end of the piston rod extends into the sealing groove and is slidably connected to the sealing groove.
[0006] A first spring is sleeved on the outer side of the piston rod, and the two ends of the first spring are fixedly connected to the inner wall of the guide frame and one side of the movable column, respectively.
[0007] The piston rod has a buffer cavity inside, which is connected to the inside of the sealing groove.
[0008] A piston plate is slidably installed inside the buffer cavity, and a second spring is fixedly installed between the piston plate and the inner wall of the buffer cavity.
[0009] The connecting assembly includes a mounting frame rotatably mounted on the other side of the movable column. The mounting frame is located on one side of the two connecting frames, and one side of each of the two connecting frames is slidably connected to the mounting frame.
[0010] The mounting frame is internally fitted with a bidirectional screw, which passes through one side of both connecting frames and is threadedly connected to both connecting frames.
[0011] A buffer pad is fixedly installed on one side of each of the two connecting frames, and both sides of the buffer pad extend out of the connecting frame and wrap around the edges of the connecting frame.
[0012] Beneficial effects
[0013] 1. Two connecting frames are used to connect concrete wall columns, and the support base is used to connect steel beams. A buffer assembly is placed between the guide frame and the connecting frames to effectively buffer vibrations transmitted by the steel beams, reduce impact at joints, and extend the lifespan of the device. The connecting assembly is used to adjust the spacing between the connecting frames to adapt to wall columns of different sizes, improving versatility and installation efficiency.
[0014] 2. The two connecting frames are connected to the mounting frame via a sliding connection structure. During installation, the two connecting frames slide on the mounting frame, allowing for spacing adjustments based on the actual width of the concrete wall column. This enables quick alignment and is suitable for installing concrete wall columns of different sizes or shapes. Attached Figure Description

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0024] The following is combined Figures 1-5 This invention describes a support device for a connection system between steel beams and concrete walls and columns.
[0025] In one embodiment, a support device for a steel beam-concrete wall column connection system, such as Figure 1 As shown, the support device for the connection system between steel beams and concrete wall columns in this embodiment includes: a support base 100, with two connecting frames 200 located on the outside of the concrete wall column on one side of the support base 100; and a connecting buffer mechanism 300, which is used to reduce vibration damage when supporting the concrete wall column and the steel beam, and is disposed between the concrete wall column and the steel beam; wherein, the connecting buffer mechanism 300 includes a guide frame 310 rotatably mounted on the top of the support base 100, a buffer assembly 320 is disposed between the guide frame 310 and the two connecting frames 200, and a connecting assembly 330 is disposed on one side of the two connecting frames 200.
[0026] In this embodiment, two connecting frames 200 are used to connect with concrete wall columns, and the support base 100 is used to connect with steel beams. The buffer component 320 is set between the guide frame 310 and the connecting frame 200, which can effectively buffer the vibration transmitted between the steel beam and the concrete wall column, play the role of energy absorption and shock reduction, thereby reducing the impact on the structural nodes and extending the service life of the support device. The connecting component 330 is used to adjust the distance between the two connecting frames 200, so that it can be flexibly adapted according to the size of the concrete wall column, improving the versatility and installation convenience of the device.
[0027] It should be noted that the existing support devices for steel beams and concrete wall columns typically include a support seat 100 for fixed connection with the steel beam, a connecting plate set on the outside of the concrete wall column, and connecting bolts or welded parts for transferring the load of the steel beam to the wall. These devices mostly adopt rigid connection methods to ensure the force transmission and structural stability of the steel beam in both vertical and horizontal directions, and are suitable for standardized building nodes.
[0028] Both the buffer assembly 320 and the connecting assembly 330 are located in the transition area between the support base 100 and the connecting frame 200. They do not participate in the force path of the steel beam body, nor do they interfere with the main force interface between the steel beam and the concrete wall column. The buffer assembly 320 provides elastic buffering only when the structure is subjected to seismic or dynamic loads, and does not weaken the initial bearing capacity of the node. The connecting assembly 330 is used to adjust the spacing of the connecting frame 200. Its adjustment action only occurs during the installation stage. After fixing, it will not cause displacement and will not adversely affect the normal stress state or long-term stability of the support device.
[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the buffer assembly 320 includes a movable column 321 slidably mounted on one side of the guide frame 310. A sealing groove 322 is provided inside the movable column 321. A piston rod 323 is fixedly connected to the inner wall of the guide frame 310. One end of the piston rod 323 extends into the sealing groove 322 and is slidably connected to the sealing groove 322.
[0030] In this embodiment, the sealing groove 322 is filled with damping oil. Under vibration, the movable column 321 can reciprocate within the guide frame 310, while the piston rod 323 slides axially within the sealing groove 322. Because the sealing groove 322 is filled with damping oil, when the piston rod 323 moves, the oil is forced to flow within the sealing groove 322, thereby generating damping resistance and effectively absorbing the impact load or vibration energy transmitted between the steel beam and the concrete wall column.
[0031] A first spring 324 is sleeved on the outer side of the piston rod 323. The two ends of the first spring 324 are fixedly connected to the inner wall of the guide frame 310 and one side of the movable column 321, respectively.
[0032] In this embodiment, when the device is subjected to vibration or impact, it can achieve automatic reset after buffering by generating elastic restoring force through the first spring 324, based on the flow resistance provided by the damping oil.
[0033] The piston rod 323 has a buffer cavity 325 inside, which is connected to the inside of the sealing groove 322.
[0034] In this embodiment, when vibration occurs, the piston rod 323 slides back and forth in the sealing groove 322, forcing the damping oil to flow between the buffer chamber 325 and the sealing groove 322 through a narrow channel, thereby forming a stable flow resistance effect during the flow process, further enhancing the buffer damping effect.
[0035] A piston plate 326 is slidably installed inside the buffer cavity 325, and a second spring 327 is fixedly installed between the piston plate 326 and the inner wall of the buffer cavity 325.
[0036] In this embodiment, when the piston rod 323 moves, the piston plate 326 can slide axially inside the buffer cavity 325. The second spring 327 provides stable elastic support, enabling the piston plate 326 to automatically rebound and reset after vibration loading. The buffer cavity 325 not only has the function of damping the flow resistance generated by the oil flow, but also can achieve multi-stage energy absorption by means of the elastic deformation of the piston plate 326 and the second spring 327, making the buffer response more sensitive and gentle, and effectively avoiding the concentrated transmission of instantaneous impact force to the connection node.
[0037] like Figure 2 , Figure 3 and Figure 5 As shown, the connecting assembly 330 includes a mounting frame 331 rotatably mounted on the other side of the movable column 321. The mounting frame 331 is located on one side of the two connecting frames 200, and one side of each of the two connecting frames 200 is slidably connected to the mounting frame 331.
[0038] In this embodiment, the two connecting frames 200 and the mounting frame 331 are connected by a sliding connection structure. During installation, the two connecting frames 200 are slidably moved on the mounting frame 331, thereby adjusting the spacing according to the actual width of the concrete wall column, quickly achieving connection alignment, and suitable for the installation needs of concrete wall columns of different sizes or shapes.
[0039] A bidirectional screw 332 is rotatably mounted inside the mounting frame 331. The bidirectional screw 332 passes through one side of both connecting frames 200 and is threadedly connected to the two connecting frames 200.
[0040] In this embodiment, when the bidirectional screw 332 is rotated, the two connecting frames 200 can move synchronously in opposite directions or back to back, thereby precisely adjusting their spacing and achieving adaptive connection for concrete wall columns of different widths. Compared with the traditional manual movement or spacer adjustment method, it has higher adjustment accuracy and ease of operation.
[0041] A buffer pad 333 is fixedly installed on one side of each of the two connecting frames 200. Both sides of the buffer pad 333 extend out of the connecting frame 200 and wrap around the edges of the connecting frame 200.
[0042] In this embodiment, the buffer pad 333 can serve as a contact buffer medium to prevent direct contact between metal parts and the wall. This not only effectively reduces the risk of damage to the wall column surface caused by hard impacts during installation, but also absorbs some of the micro-vibrations or impact forces transmitted in the connection area during use, reducing the accumulation of fatigue at the joints. The edge-wrapping design of the buffer pad 333 further enhances the wrapping stability and anti-detachment performance, preventing the buffer material from shifting due to long-term vibration or temperature difference deformation.
[0043] Working Principle: During use, the support base 100, connected to the steel beam, transfers the load of the steel beam to the concrete wall column. Two connecting frames 200 are fixed to the outside of the concrete wall column and are positioned and connected to the support base 100 via the connecting assembly 330. The mounting frame 331 in the connecting assembly 330 connects the two connecting frames 200 through a sliding fit, and is driven by an internal bidirectional screw 332 to move the two connecting frames 200 synchronously, enabling installation to accommodate wall columns of different widths, improving installation accuracy and ease of construction. If vibration or impact loads occur during the operation of the steel beam or during overall structural stress, the load is transmitted to the connecting buffer mechanism 300 through the support base 100. At this time, the movable column 321 located on one side of the guide frame 310 will slide under vibration, causing the internal piston rod 323 to slide in the sealing groove 322, compressing the damping oil and causing the oil to flow into the buffer chamber 325 through a narrow channel, achieving primary damping buffering. Simultaneously, the piston plate 326 inside the buffer chamber 325 slides backward under the action of oil pressure and inertia, compressing the second spring 327 to further absorb the remaining impact energy, forming a multi-stage buffering process. The first spring 324 on the outside of the piston rod 323 is also compressed synchronously, providing a rebound force to the system and ensuring that the buffer mechanism quickly returns to its original state after the vibration is eliminated. The buffer pad 333 set on the connecting frame 200 can absorb micro-vibrations and off-center stress when in contact with the wall column, avoiding damage caused by hard contact and further improving the fatigue resistance and stability of the overall structure.
[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
