Description

Technical Field

[0001] This utility model relates to the field of earthquake-resistant building technology, and more specifically, to a seismic-resistant reinforcement structure for buildings. Background Technology

[0002] Seismic reinforcement structures for buildings are designed to improve the compressive strength, ductility, integrity, and support methods of buildings to ensure that they meet the prescribed seismic fortification requirements.

[0003] Patent CN217602198U discloses a seismic reinforcement structure for building walls. It includes connectors between two walls, with each set of flanges forming an embedded groove between the flange and the steel pipe, into which the wall is embedded. The steel pipe and buffer effectively absorb and release the compressive impact force when the wall is compressed against the steel pipe. Inserted pins are used to connect the steel pipe to the wall through the mounting grooves; fixing pins pass through fixing holes on the flanges and the wall to maintain a stable connection. However, fixing the seismic reinforcement structure to the wall requires inserting each fixing pin individually, which is cumbersome and inconvenient. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a seismic reinforcement structure for buildings.

[0006] The connector includes a tube body, embedded plates located on opposite sides of the tube body, and baffles for abutting against the precast component; the precast component has a first embedded groove on the end face adjacent to the connector, the first embedded groove being used to accommodate the embedded plates;

[0007] The connector also has at least two snap-fit ​​pieces for connecting to the precast component, with the openings of the two snap-fit ​​pieces facing away from each other.

[0008] Furthermore, the prefabricated component is a prefabricated wall.

[0009] Furthermore, the tube body is a square tube, and a buffer element is installed inside the tube body. The tube body has sufficient strength and a certain deformation capacity to effectively absorb the impact force when the tube body is impacted by the precast component. The internal buffer element is used to further absorb and release the pressure generated when the precast component impacts the tube body.

[0010] Furthermore, the buffer is a cross plate arranged in a cross pattern or a wave plate with a wavy structure, and the surface of the buffer is covered with a damping coating.

[0011] Furthermore, the embedded plates arranged on opposite sides of the tube body are respectively referred to as the first embedded plate and the second embedded plate; baffles are fixed to the other opposite sides respectively.

[0012] Furthermore, the first and second embedded plates are respectively provided with two parallel pieces; each of the first embedded plates has a first snap-fit ​​groove, and each of the second embedded plates has a second snap-fit ​​groove.

[0013] Each of the baffles is provided with a third locking groove;

[0014] Each of the first snap-fit ​​slots is flush with one of the third snap-fit ​​slots, and each of the second snap-fit ​​slots is flush with the other of the third snap-fit ​​slots, so that the snap-fit ​​components can be snapped into place respectively.

[0015] Furthermore, a mounting plate is also provided at the third snap-fit ​​groove of the baffle, and the mounting plate is used to connect the snap-fit ​​component.

[0016] Furthermore, the snap-fit ​​component is C-shaped and includes a first side plate, a middle plate, and a second side plate that are arranged sequentially and integrally. The first side plate and the second side plate are parallel to each other, and the length of the first side plate is longer than the length of the second side plate.

[0017] Furthermore, the prefabricated component is provided with embedded sleeves, the positions of which are adapted to the installation positions of the first side plates of each of the snap-fit ​​components;

[0018] The prefabricated component is also provided with a second embedding groove for accommodating the closed end of the snap-fit ​​component.

[0019] Furthermore, the free end of the first side plate is connected to the embedded sleeve of the precast component, and the first side plate is provided with a first connecting hole connected to the precast component and a second connecting hole connected to the mounting plate.

[0020] The free end of the second side plate abuts against the side wall of the precast component; the second side plate has a third connecting hole for connecting the mounting plate.

[0021] Furthermore, the first connecting hole, the second connecting hole, and the third connecting hole are all countersunk holes.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The seismic-resistant reinforcement structure of this building utilizes a snap-fit ​​mechanism. This mechanism connects the snap-fit ​​components to the prefabricated wall components, including embedded sleeves and mounting plates. This design allows for bolt-on installation, simplifying the process, improving construction efficiency, and reducing installation time. By connecting the snap-fit ​​components to the prefabricated wall components and mounting plates, the cumbersome process of inserting fixing pins one by one, as required by existing technologies, is avoided. Furthermore, the fit between the embedded plate and the embedded groove, along with the snap-fit ​​groove design, enables the connectors to be installed quickly and accurately, further optimizing the construction process.

[0024] Furthermore, by setting different snap-fit ​​grooves on the first embedded plate, second embedded plate, and baffle of the connector, and using them in conjunction with the snap-fit ​​component, a tight connection between the connector and the precast component is achieved. The first side plate of the snap-fit ​​component is bolted to the embedded sleeve of the precast component, and the second side plate is bolted to the mounting plate. This dual connection method significantly improves the connection stability between the connector and the precast wall, ensuring that the wall and the connector will not loosen or fall off under external forces such as earthquakes.

[0025] Furthermore, the connector design is better adapted to the structural characteristics of precast components such as precast walls. By setting embedding grooves on the end faces of the precast components, the corresponding embedding plates in the connectors can be tightly embedded, making the connectors and precast components a unified whole. This design not only improves the integrity of the wall structure but also enhances the collaborative seismic resistance between the wall structure and the connectors, ensuring that the building maintains its structural integrity under earthquake loads.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] like Figures 1-6 As shown, this embodiment provides a seismic reinforcement structure for a building, including a connector located between two prefabricated components 1. In this embodiment, the prefabricated component 1 is a prefabricated wall. The connector includes a pipe body 2, embedded plates located on opposite sides of the pipe body 2, and a baffle 3 for abutting against the prefabricated component 1. A first embedded groove 11 is provided on the end face of the prefabricated component 1 adjacent to the connector, and the first embedded groove 11 is used to accommodate the embedded plate. The connector also has at least two snap-fit ​​pieces 4 for connecting to the prefabricated component 1. The openings of the two snap-fit ​​pieces face opposite directions and can respectively connect the prefabricated components 1 on both sides of the snap-fit ​​piece 4.

[0042] Specifically, such as Figures 1-5As shown, pipe body 2 is a square tube, and a buffer component is installed inside. Pipe body 2 has sufficient strength and a certain deformation capacity to effectively absorb the impact force when it is impacted by precast components. The buffer component installed inside pipe body 2 is used to further absorb and release the pressure generated when the precast components impact the pipe body. The buffer component consists of intersecting plates or corrugated plates with a wavy structure, and a damping coating is applied to the surface of the buffer component to further enhance the buffering effect. The intersecting plates are arranged in pairs and are made of alloy metal plates with a certain elastic deformation capacity. The two ends of each intersecting plate are welded and fixed to the inner walls of the two opposite sides of the pipe body. Furthermore, the intersecting plates are connected sequentially along the length of the pipe body. Thus, when two precast walls exert a squeezing impact force on the pipe body, the pipe body itself and the intersecting plates effectively mitigate and release the impact force, maintaining a stable connection with the two precast walls. The corrugated plates are made of a metal alloy with a certain elastic deformation capacity. The corrugated plate extends along the length of the pipe, and the protrusions on both sides of the corrugated plate are welded and fixed to the inner walls of the pipe to buffer and release the impact force on the pipe and reduce the damage caused by rigid compression between precast walls.

[0043] In this embodiment, as Figures 2-5 As shown, the embedded plates arranged on opposite sides of the pipe body 2 are respectively designated as the first embedded plate 5 and the second embedded plate 6; additionally, baffles 3 are fixedly connected to opposite sides. The first embedded plate 5 and the second embedded plate 6 are arranged in parallel sections, meaning that on one side of the pipe body 2, two parallel first embedded plates 5 are arranged, and on the opposite side, two parallel second embedded plates 6 are arranged. Each first embedded plate 5 has a first engaging groove 51, and each second embedded plate 6 has a second engaging groove 61. Two baffles 3 are fixedly connected to the other two sides of the pipe body 2, and each baffle 3 has a third engaging groove 31. Furthermore, in this embodiment, on one side of the tube body 2, each first embedded plate 5 is provided with two first snap-fit ​​grooves 51, and on the other side, each second embedded plate 6 is provided with two second snap-fit ​​grooves 61. That is, the first snap-fit ​​grooves 51 face to the left, and the second snap-fit ​​grooves 61 face to the right. In other words, the first snap-fit ​​grooves 51 and the second snap-fit ​​grooves 61 face opposite directions, and the first snap-fit ​​grooves 51 and the second snap-fit ​​grooves 61 are arranged alternately. At the same time, each first snap-fit ​​groove 51 is flush with one of the third snap-fit ​​grooves 31, and each second snap-fit ​​groove 61 is flush with another of the third snap-fit ​​grooves 31, respectively used to snap onto the corresponding snap-fit ​​component 4.

[0044] Furthermore, the third snap-fit ​​groove of the baffle 3 is also provided with a mounting plate 7, which is used to connect the snap-fit ​​component 4.

[0045] In this embodiment, the snap-fit ​​component 4 is C-shaped and includes a first side plate 41, a middle plate 42 and a second side plate 43 arranged sequentially and integrally. The first side plate 41 and the second side plate 43 are parallel to each other and the length of the first side plate 41 is longer than the length of the second side plate 43.

[0046] Correspondingly, pre-embedded sleeves 12 are provided on the precast component 1, and their positions are adapted to the installation positions of the first side plates 41 of each snap-fit ​​component 4; a second embedding groove 13 is also provided on the precast component 1 to accommodate the closed end of the snap-fit ​​component 4. The free end of the first side plate 41 is connected to the pre-embedded sleeve 12 of the precast component 1, and the first side plate 41 has a first connecting hole 411 connected to the precast component 1 and a second connecting hole 412 connected to the mounting plate 7. The free end of the second side plate 43 abuts against the side wall of the precast component 1; the second side plate 43 has a third connecting hole 431 for connecting the mounting plate 7. The mounting plate 7 has a fourth connecting hole 71 for connection.

[0047] To elaborate further, the first connecting hole 411, the second connecting hole 412 and the third connecting hole 431 are countersunk holes. The purpose of the countersunk hole design is to ensure that the bolt nut is below the plane and does not protrude from the plane.

[0048] In this embodiment, the first embedding groove 11 in the precast component 1, i.e., the precast wall, is used to clamp the first embedding plate 5 or the second embedding plate 6 on one side of the pipe body 2. Since there are two first embedding plates 5 and two second embedding plates 6 respectively, there are two first embedding grooves 11 on one side of the precast component 1. At the same time, since the snap-fit ​​component 4 is sleeved on the connector, a second embedding groove 13 is also provided on the side of the precast component to accommodate the closed end of the snap-fit ​​component 4. The first embedding grooves 11 respectively opened on the end face of the precast wall are adapted to the corresponding embedding plates of the connector; the second embedding grooves 13 are adapted to the middle plate 42 of the snap-fit ​​component 4. After the precast component is connected to the snap-fit ​​component 4, a third embedding groove 14 is also opened on one side of the first plate 41 to accommodate the first plate 41 of the snap-fit ​​component 4. Meanwhile, the prefabricated component is also provided with embedded sleeves 12 that are compatible with the first connection holes 411 of each snap-fit ​​component 4, and the snap-fit ​​components 4 that are snapped to the connector are fixed to the corresponding positions of the prefabricated component 1 by bolts.

[0049] In this embodiment, a square tube is selected as the tube body to ensure sufficient strength and a certain deformation capacity. An internal buffer is installed to absorb impact forces. A first embedded plate 4 and a second embedded plate 5 are fixedly attached to opposite sides of the tube body 2, two on each side. Two baffles 3 are fixedly attached to the other two sides of the tube body 3, the dimensions of which are adapted to the side walls of the tube body. Furthermore, the first embedded plate 5, the second embedded plate 6, and the baffles 3 are respectively provided with a first snap-fit ​​groove 51, a second snap-fit ​​groove 61, and a third snap-fit ​​groove 31 to facilitate the installation of the snap-fit ​​component 4.

[0050] Specifically, such as Figures 2-6 As shown, the first side plate 41 and the third side plate 43 of the snap-fit ​​component 4 are respectively located in the third snap-fit ​​groove 31 of the baffle. The middle plate 42 of the snap-fit ​​component 4 is located in the first snap-fit ​​groove 41 of the first embedded plate 4 or in the second snap-fit ​​groove 51 of the second embedded plate 5, thereby forming a snap-fit ​​of the snap-fit ​​component 4 on the connector. Then, the first side plate 41 of the snap-fit ​​component 4 is bolted to the embedded sleeve 12 of the precast wall. The bolt passes through the first connecting hole 411 on the first side plate and the threaded hole in the embedded sleeve 12. The second side plate 43 of the snap-fit ​​component 4 is abutted against the side wall of the precast wall and bolted to the mounting plate 7. The bolt passes through the third connecting hole 431 on the second side plate 43 and the fourth connecting hole 71 on the mounting plate 7. The fourth connecting hole 71 is a threaded hole. The free end of the first side plate of the snap-fit ​​part 4 is fixed to the pre-embedded sleeve of the precast part 1 by bolts. At the same time, it is connected to the baffle 3 through the second connecting hole 412 and the third connecting hole 431, thus realizing the structure of connecting two adjacent precast parts through the snap-fit ​​part.

[0051] The seismic reinforcement structure for buildings provided in this embodiment first completes the assembly of the snap-fit ​​component 4 and the connector: the snap-fit ​​component 4 is snapped into the first snap-fit ​​groove 51 of the first embedded plate 5, the second snap-fit ​​groove 61 of the second embedded plate 6, and the third snap-fit ​​groove 31 on the baffle 3, ensuring a tight fit between the snap-fit ​​component and the connector. At this time, the first side plate 41 and the second side plate 43 are respectively located in the third snap-fit ​​groove 31 of the baffle 3, and the middle plate 42 is partially located in the first snap-fit ​​groove 51 of the first embedded plate 5 or the second snap-fit ​​groove 61 of the second embedded plate 6, so as to facilitate the connection of the prefabricated components on both sides of the connector in this embodiment. Then, the prefabricated component 1 is hoisted to the designated position, so that the first embedded plate 5 or the second embedded plate 6 is embedded in the first embedded groove 11 of the prefabricated component 1, and at the same time, the middle plate 42 of the snap-fit ​​component 4 is embedded in the second embedded groove 13 of the prefabricated component 1, fitting tightly to ensure the initial connection between the prefabricated component 1 and the connector. Then, the first side plate 41 of the snap-fit ​​component 4 is connected to the embedded sleeve 12 of the prefabricated component 1, i.e., the prefabricated wall, using bolts. Bolts are passed sequentially through the first connecting hole 411 on the first side plate 41 and the threaded hole in the pre-embedded sleeve 12, and tightened to fix the snap-fit ​​component to the precast wall. Bolts are then used to connect the second side plate 43 of the snap-fit ​​component 4 to the mounting plate 7 at the baffle 3, and simultaneously, the second connecting hole 412 of the first side plate 41 is also bolted to the mounting plate 7 at the baffle 3. The bolts are tightened to complete the installation of the snap-fit ​​component 4. At this point, the seismic reinforcement structure of this building is installed. Through the above steps, a seismic reinforcement structure with cross-plate buffers is formed, which can effectively absorb the impact force between precast walls and enhance seismic performance. After installation, the connectors and snap-fit ​​components can be facing outwards towards any gaps, and concrete can be poured in place using wooden formwork.

[0052] If multiple precast components need to be connected, the above steps can be repeated to install multiple connectors sequentially between adjacent precast components, i.e., precast walls, to form a continuous seismic-resistant reinforcement structure. Ensure that all connectors and snap-fit ​​parts 4 are securely installed, and that the precast walls are tightly connected to form a unified seismic-resistant structure.

[0053] The seismic reinforcement structure for buildings provided in this embodiment utilizes a snap-fit ​​connector 4 structure. C-shaped snap-fit ​​connectors are used to connect the precast component 1 (i.e., the precast wall's embedded sleeve 12) and the mounting plate 7 of the connector. This design allows for fixation solely through bolt connections, simplifying the operation process, improving construction efficiency, and reducing installation time and labor costs. By connecting the snap-fit ​​connector to the precast wall's embedded sleeve and mounting plate, the cumbersome operation of inserting fixing pins one by one, as required in existing technologies, is avoided. Furthermore, the fit between the embedded plate and the embedded groove, along with the design of the snap-fit ​​groove, enables the connector to be installed quickly and accurately, further optimizing the construction process and improving construction quality.

[0054] By setting different snap-fit ​​grooves on the first embedded plate 5, the second embedded plate 6, and the baffle 3 of the connector, and using them in conjunction with the snap-fit ​​part 4, a tight connection between the connector and the precast part 1 is achieved. The first side plate 41 of the snap-fit ​​part 4 is bolted to the embedded sleeve 12 of the precast part 1, and the second side plate 43 is bolted to the mounting plate 7. This dual connection method significantly improves the connection stability between the connector 7 and the precast wall, ensuring that the wall and the connector will not loosen or fall off under the action of external forces such as earthquakes.

[0055] A cross plate or corrugated plate is installed inside the pipe body 2 of the connector as a buffer, and a damping coating is applied to its surface. Both the cross plate and the corrugated plate are made of alloy metal plates with a certain elastic deformation capacity, which can effectively absorb and release impact force and reduce rigid collisions between prefabricated walls. In addition, the pipe body 2 itself also has sufficient strength and a certain deformation capacity, further enhancing its seismic performance.

[0056] In this embodiment, the connector design is better adapted to the structural characteristics of precast components such as precast walls. By providing an embedding groove on the end face of the precast component 1, the corresponding embedding plate in the connector can be tightly embedded therein, making the connector and the precast component 1 form a whole. This design not only improves the integrity of the wall but also enhances the collaborative seismic resistance between the wall and the connector, ensuring that the building maintains its structural integrity under earthquake loads.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
