Description

Technical Field

[0001] This application belongs to the technical field of shock-absorbing connection structures, and more specifically, relates to an assembled self-centering shock-absorbing connection structure. Background Art

[0002] An assembled self-centering shock-absorbing connection structure is a structural system that combines precast components with a self-centering shock-absorbing device through a specific connection method. This structure can utilize the shock-absorbing device to absorb and dissipate seismic energy, and at the same time, through the self-centering mechanism, the structure can return to its initial position after an earthquake, thereby reducing structural damage and improving safety. The assembled self-centering shock-absorbing connection structure is applicable to various types of building structures, including residential buildings, commercial buildings, public facilities, etc. Especially in earthquake-prone areas, this structure can significantly improve the seismic performance of the structure and ensure the safety of people's lives and property.

[0003] Currently, during the assembly and use of precast walls, the connection structure between precast walls is prone to deformation and even damage under vibration; and after vibration occurs, the deformation of the connection structure between precast walls accumulates, making it difficult to reset. During long-term use, it is easy to cause the connection structure between precast walls to break, and then the wall collapses, endangering the lives of residents. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide an assembled self-centering shock-absorbing connection structure. A shock-absorbing component is used to eliminate the generated vibration, which can effectively ensure that when the first wall panel and the second wall panel stop vibrating, they can automatically reset, and the first wall panel and the second wall panel are connected in a shock-absorbing manner through an elastic clamping member.

[0005] To achieve the above purpose, the technical solution adopted in this application is: providing an assembled self-centering shock-absorbing connection structure, including a first wall panel and a second wall panel, and a shock-absorbing component is installed between the first wall panel and the second wall panel;

[0006] On one side of the first wall panel close to the second wall panel, there is a first groove, and at the bottom of both ends of the first groove, there are second grooves respectively. At the position corresponding to the second grooves on the second wall panel, there are docking rods. One end of the docking rod is fixed on the second wall panel, and the other end is provided with an elastic clamping member, and the elastic clamping member is clamped in the second groove;

[0007] The shock-absorbing component is accommodated in the first groove, and one end of it is fixed on the first wall panel, and the other end is fixed on the second wall panel.

[0008] In one embodiment, the shock absorption assembly includes: a shock absorption shell, in which a shock absorption rod and a second spring are provided. At the ends of the shock absorption shell and the shock absorption rod that are away from each other, first connecting rods are respectively provided. A fixing bracket is provided on each first connecting rod, and the corresponding fixing bracket is connected to the first wall panel or the second wall panel; a pulling rope is provided on the first connecting rod at one end of the shock absorption rod, and the pulling rope is connected to the second wall panel.

[0009] In one embodiment, the elastic clamping member includes: two first springs symmetrically arranged on the docking rod. A fixing block is provided at the end of the first spring away from the docking rod. A limiting bracket is movably arranged on the docking rod. A notch for accommodating the two fixing blocks and keeping the first spring in a compressed state is provided on the limiting bracket, and the length of the limiting bracket is greater than the length of the second groove.

[0010] In one embodiment, a detection rod is provided on the docking rod close to the shock absorption shell. A third groove is provided at one end of the first connecting rod on the shock absorption shell, and one end of the detection rod is slidably assembled with the third groove.

[0011] In one embodiment, a fixing rod is provided on the second wall panel. One end of the pulling rope is fixed to the fixing rod, and the other end is fixed to the shock absorption rod through a pulley on the shock absorption rod.

[0012] In one embodiment, a second connecting rod is provided on the first connecting rod. The second connecting rod is a rotating shaft. The fixing bracket is of a U-shaped structure, and the open end of the fixing bracket is rotatably installed on the first connecting rod through the second connecting rod.

[0013] In one embodiment, fixing screws are provided on the bottom plate of the fixing bracket. After passing through the bottom plate, the fixing screws are connected to the first wall panel or the second wall panel.

[0014] Another object of the present application is to provide a construction method of an assembled self-resetting shock absorption connection structure. Based on the above-mentioned assembled self-resetting shock absorption connection structure, the construction method includes the following steps:

[0015] Step S1: Make a construction table. An assembly groove is provided on the construction table. A pushing plate is provided in the assembly groove. A motor is provided on the construction table. The motor is drivingly connected to a threaded rod. A moving sleeve is threadedly connected to the threaded rod. The pushing plate is fixedly connected to the moving sleeve;

[0016] Step S2: The construction worker places the first wall panel and the second wall panel in the assembly groove of the workbench. The shock absorption assembly is fixedly connected to the first wall panel and the second wall panel respectively through the fixing screws on the fixing brackets at both ends. The pushing plate is located on the side of the second wall panel away from the first wall panel;

[0017] Step S3, starting the motor, the motor drives the threaded rod to rotate, so that the threaded rod drives the moving sleeve to move, the push plate moves forward with the moving sleeve, and pushes the second wall panel to move closer to the first wall panel for connection;

[0018] Step S4, when the second wall panel moves closer, the second groove on the first wall panel blocks the limiting frame. When the second wall panel continues to be pushed to move, the fixed block and the first spring extend into the second groove. When the fixed block is completely separated from the limiting effect of the limiting frame, the first spring automatically resumes its extension and stretches the fixed block to abut against the second groove. At this time, the detection rod is assembled in the third groove.

[0019] The beneficial effects of the assembled self-resetting shock-absorbing connection structure and construction method provided by the present application are: elastic deformation will occur between the first wall panel and the second wall panel through the second spring inside the shock-absorbing assembly, and the vibration power will be converted into heat energy and dissipated, so as to reduce the shock between the wall panels and strengthen the connection between the wall panels. In addition, with the design of the elastic clip and the second spring, the first wall panel and the second wall panel can automatically reset when they are no longer vibrating, thereby preventing the connection structure between the assembled walls from deforming and accumulating after vibration, which makes it difficult to reset and causes the connection structure between the assembled walls to break.

In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0034] As Figures 1 - 5 shown, a prefabricated self-centering shock-absorbing connection structure provided by an embodiment of this application will now be described. This prefabricated self-centering shock-absorbing connection structure is used to connect a first wall panel 1 and a second wall panel 2. Specifically, a shock-absorbing component 3 is installed between the first wall panel 1 and the second wall panel 2. A first groove 101 is provided on one side of the first wall panel 1 close to the second wall panel 2. Second grooves 102 are respectively provided at the bottom ends of both ends of the first groove 101. A docking rod 201 is provided at a position on the second wall panel 2 corresponding to the second groove 102. One end of the docking rod 201 is fixed to the second wall panel 2, and an elastic clamping member is provided at the other end. When the first wall panel 1 and the second wall panel 2 are spliced, the elastic clamping member is clamped in the second groove 102, initially realizing the shock-absorbing connection between the first wall panel 1 and the second wall panel 2.

[0035] Among them, the shock-absorbing component 3 is accommodated in the first groove 101, and one end of it is fixed to the first wall panel 1 and the other end is fixed to the second wall panel 2, and is used to eliminate the vibration between the first wall panel 1 and the second wall panel 2.

[0036] Specifically, as Figures 3 - 5 shown, the shock-absorbing component 3 includes: a shock-absorbing shell 301. A shock-absorbing rod 303 and a second spring 302 are provided in the shock-absorbing shell 301. The second spring 302 is sleeved on the shock-absorbing rod 303. The shock-absorbing shell 301 plays a protective role. The shock-absorbing rod 303 is equivalent to a damper and forms a shock absorber together with the second spring 302. One end of the shock-absorbing rod 303 extends out of the shock-absorbing shell 301, and the second spring 302 is placed in the shock-absorbing shell 301. In this embodiment, first connecting rods 304 are respectively provided at the ends of the shock-absorbing shell 301 and the shock-absorbing rod 303 that are away from each other, that is, first connecting rods 304 are respectively provided at both ends of the shock-absorbing component 3; a fixing bracket 305 is provided on each first connecting rod 304. One fixing bracket 305 is connected to the first wall panel 1, and the other fixing bracket 305 is connected to the second wall panel 2, thereby realizing the shock-absorbing connection between the shock-absorbing component 3 and the first wall panel 1 and the second wall panel 2. In this embodiment, a pull rope 309 is provided on the first connecting rod 304 at one end of the shock-absorbing rod 303. The pull rope 309 is connected to the second wall panel 2. The pull rope 309 has a certain elasticity, and the pull rope 309 is used to assist in bringing the second wall panel 2 closer to the first wall panel 1.

[0037] As Figure 2 and Figure 3As shown, the elastic clamping member includes: two first springs 202 symmetrically arranged on the docking rod 201, a fixing block 203 is provided on one end of the first spring 202 away from the docking rod 201, and a limiting frame 204 is movably provided on the docking rod 201. The limiting frame 204 is provided with a notch for accommodating the two fixing blocks 203 and putting the first spring 202 in a compressed state, and the notch is arranged toward the first wall panel 1. The length of the limiting frame 204 is greater than the length of the second groove 102, that is, the limiting frame 204 cannot be inserted into the second groove 102, and the first spring 202 and the fixing block 203 in the compressed state can be inserted into the second groove 102. When the limiting frame 204 cancels the limiting effect on the first spring 202, the first spring 202 automatically recovers and opens the fixing block 203, so that the fixing block 203 abuts against the side wall of the second groove 102, thereby realizing the elastic assembly of the elastic clamping member and the first wall panel 1.

[0038] The second groove 102 is a rectangular groove, and the fixing block 203 is a rectangular block. Preferably, a guiding slope is provided on the side of the fixing block 203 close to the first wall panel 1, so that it is convenient to insert into the second groove 102, thereby realizing the rapid assembly of the first wall panel 1 and the second wall panel 2.

[0039] In this embodiment, a detection rod 205 is provided on the docking rod 201 close to the shock-absorbing shell 301, and a third groove 310 is provided at one end of the first connecting rod 304 on the shock-absorbing shell 301, and one end of the detection rod 205 is slidably assembled with the third groove 310. When the first wall panel 1 and the second wall panel 2 are docked, the shock-absorbing assembly 3 is horizontally accommodated in the first groove 101, and one end of the detection rod 205 is inserted into the third groove 310, so as to detect whether the shock-absorbing assembly 3 is horizontally installed in place.

[0040] In this embodiment, a fixing rod 206 is provided on the second wall panel 2, one end of a pull rope 309 is fixed on the fixing rod 206, a pulley 308 is provided on the first connecting rod 304 on the shock absorbing rod 303, and the other end of the pull rope 309 is fixed on the shock absorbing rod 303 after passing through the pulley 308.

[0041] In this embodiment, each first connecting rod 304 is provided with a second connecting rod 306 , the second connecting rod 306 is a rotating shaft, the fixing frame 305 is a U-shaped structure, and the open end of the fixing frame 305 is rotatably mounted on the first connecting rod 304 through the second connecting rod 306 .

[0042] In this embodiment, a fixing screw 307 is provided on the bottom plate of the fixing frame 305, and the fixing screw 307 penetrates through the bottom plate and is connected to the first wall plate 1 or the second wall plate 2. For the purpose of installation firmness, nuts are embedded in the holes on the first wall plate 1 and the second wall plate 2, and the fixing screw 307 is threadedly connected with the nut; or, before the fixing screw 307 is screwed in, some glue is applied, and when the fixing screw 307 is threadedly connected with the nut, the glue will solidify, which can effectively prevent the fixing screw 307 from loosening.

[0043] Please refer to Figures 1 - 5 This embodiment also provides a construction method of an assembled self-resetting shock-absorbing connection structure. Based on the assembled self-resetting shock-absorbing connection structure as described above, the construction method includes the following steps:

[0044] Step S1, making a construction platform, the construction platform is provided with an assembly groove, the assembly groove is provided with a push plate, the construction platform is provided with a motor 502, the motor 502 is transmission-connected with a threaded rod 503, the threaded rod 503 is threadedly connected with a movable sleeve 504, the push plate and the movable sleeve 504 are fixedly connected; the threaded rod 503 is equivalent to a screw rod, and the movable sleeve 504 is equivalent to a screw rod pair.

[0045] Step S2, the construction workers place the first wall panel 1 and the second wall panel 2 in the assembly groove of the workbench 501, and the shock-absorbing assembly 3 is fixedly connected to the first wall panel 1 and the second wall panel 2 respectively through the fixing screws on the fixing frames 305 at both ends, and the push plate 505 is located on the side of the second wall panel 2 away from the first wall panel 1; at this time, the fixing rod 206 is fixed on the second wall panel 2.

[0046] Step S3, start the motor 502, the motor 502 drives the threaded rod 503 to rotate, so that the threaded rod 503 drives the moving sleeve 504 to move, the push plate 505 moves forward with the moving sleeve 504, and pushes the second wall panel 2 to move closer to the first wall panel 1 for connection;

[0047] Step S4, when the second wall panel 2 moves closer, the second groove 102 on the first wall panel 1 blocks the limiting frame 204. When the second wall panel 2 continues to be pushed to move, the fixed block 203 and the first spring 202 extend into the second groove 102. When the fixed block 203 is completely separated from the limiting effect of the limiting frame 204, the first spring 202 automatically resumes its extension and stretches the fixed block 203 to abut against the second groove 102. At this time, the detection rod 205 is assembled in the third groove 310.

[0048] When the first wall panel 1 and the second wall panel 2 vibrate, the generated vibration force will be eliminated by the shock absorbing assembly 3; when the first wall panel 1 and the second wall panel 2 no longer vibrate, the first wall panel 1 and the second wall panel 2 are automatically reset by the shock absorbing assembly 3 and the elastic clip.

[0049] Specific working principle: Start the motor 502. The motor 502 drives the threaded rod 503 to rotate. Thus, the threaded rod 503 drives the moving sleeve 504 to move forward. The push plate 505 follows the moving sleeve 504 to move forward. Thus, the moving sleeve 504 pushes the second wall panel 2 towards the first wall panel 1 for connection, assisting in the rapid connection of the wall panels.

[0050] When the second wall panel 2 approaches the first wall panel 1 for connection, the first wall panel 1 blocks and restricts the movement of the limiting frame 204, causing the first spring 202 and the fixed block 203 inside the limiting frame 204 to continue moving forward with the second wall panel 2 through the docking rod 201. After the first spring 202 and the fixed block 203 are separated from the limiting frame 204, the first spring 202 undergoes elastic deformation, causing the fixed block 203 to be stuck in the second groove 102, strengthening the connection between the first wall panel 1 and the second wall panel 2. At the same time, the detection rod 205 is inserted into the internal part of one side of the third groove 311 to detect whether the shock absorption component is placed horizontally inside the first groove.

[0051] When the first wall panel 1 and the second wall panel 2 vibrate, elastic deformation occurs to the second spring 302 inside the shock absorption component 3 between the first wall panel 1 and the second wall panel 2, converting the vibration power into heat energy and dissipating it. Because the spring is elastic, when the first wall panel 1 and the second wall panel 2 stop vibrating, they can automatically reset, preventing the deformation accumulation of the connection structure between the prefabricated wall panels after vibration and making it difficult to reset, resulting in the fracture of the connection structure between the prefabricated wall panels. When the second spring 302 undergoes elastic deformation, when the shock absorption rod 303 moves following the elastic deformation of the second spring 302, it will pull the pull rope 309. Thus, the other side of the pull rope 309 drives the second wall panel 2 towards the first wall panel 1, assisting in the connection between the first wall panel 1 and the second wall panel 2 and strengthening the connection between the wall panels.

[0052] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
