Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically a sealing and waterproofing buffer device for the joints of prefabricated building wall panels. Background Technology

[0002] Prefabricated buildings are widely used in the construction industry due to their advantages such as fast construction speed and good environmental protection. As an important component of prefabricated buildings, the treatment of the joints of wall panels directly affects the overall performance of the building.

[0003] Currently, the joints of prefabricated building wall panels are usually sealed with simple sealant. This method is prone to sealant cracking when the wall panels expand or contract due to temperature changes or external impacts, leading to waterproofing failure. At the same time, the lack of an effective buffer structure means that external forces acting directly on the joints can easily damage the wall panels, affecting the building's service life and safety. To address this, we propose a sealing, waterproofing, and buffering device for the joints of prefabricated building wall panels. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing, waterproofing, and buffering device for the joints of prefabricated building wall panels, to solve the problems of poor waterproofing and lack of buffering function in existing wall panel joint treatment methods mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a sealing, waterproofing, and buffering device for the joints of prefabricated building wall panels, including a fixing plate;

[0005] The buffer assembly includes several springs, each fixedly connected to a side opposite to a fixed plate. A push plate is fixedly connected to the opposite side of each spring, and two fixed brackets are fixedly connected to the opposite side of each push plate. A fixed rod is fixedly connected to the side of the two fixed brackets that are close together. A rotating block is rotatably connected to the side surface of the fixed rod, and a support plate is fixedly connected to one side of the rotating block. When using this device, the buffer assembly and springs form a double buffer structure. When the wall panel is subjected to external impact or temperature expansion / contraction, springs provide initial buffering, and the push plate further buffers the springs by pressing them, effectively reducing the impact of external forces on the joint. In the limiting assembly, a sliding rod slides within a limiting groove, cooperating with the sliding connection between limiting block 2 and limiting block 1 to ensure stable movement of the components during buffering and prevent displacement. The elastic pad not only provides secondary buffering, but its outer sealing gasket always adheres to the mounting plate, ensuring a sealing and waterproof effect.

[0006] A limiting component, comprising a plurality of limiting frames, which are respectively fixedly connected to one side of a fixed plate opposite to each other, and each of the limiting frames has a limiting groove on its top.

[0007] More preferably, the limiting component further includes two slide rods, which are slidably connected inside the limiting groove.

[0008] More preferably, the side surfaces of the two slide bars are respectively fixedly connected to a rotating block two, and one side of the rotating block two is fixedly connected to the other side of the support plate.

[0009] More preferably, two limiting blocks are fixedly connected to one side of the fixed plate opposite to each other, a plurality of springs are fixedly connected to one side of the fixed plate opposite to each other, and an installation assembly is provided on the outer side of the fixed plate.

[0010] More preferably, the mounting assembly includes two mounting plates, which are respectively disposed on one side and the other side of the fixed plate. The side of the mounting plates that are close to each other is fixedly connected to the side opposite to the side of a plurality of push plates and springs. Two limiting blocks are fixedly connected to the side of the two mounting plates that are close to each other.

[0011] More preferably, the outer side of the second limiting block is slidably connected to the outer side of the second limiting block, and trapezoidal locking blocks are fixedly connected to the opposite sides of the two mounting plates respectively.

[0012] More preferably, elastic pads are fixedly connected to one opposite side of each of the two limiting blocks, and sealing pads are fixedly connected to one opposite side of each of the two elastic pads.

[0013] In a further preferred embodiment, a wall panel body is provided on each of the two mounting plates facing away from each other, and a slot is provided on each of the wall panel bodies facing away from each other. The inside of the slot engages with the outside of the trapezoidal locking block. During installation, the mounting components achieve rapid assembly of the device and the wall panel through the engagement of the trapezoidal locking block and the slot, improving construction efficiency. The overall structural design is reasonable, with good buffering performance and sealing and waterproofing performance, extending the service life of the wall panel and improving the safety of the building.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, when using the device, a double buffer structure is formed by setting up a buffer component and a second spring. When the wall panel body is subjected to external impact or temperature expansion and contraction, the second spring first performs initial buffering, and the push plate squeezes the first spring to achieve further buffering, effectively reducing the impact of external force on the joint. In the limiting component, the sliding rod slides in the limiting groove, and the sliding connection between the second limiting block and the first limiting block ensures stable movement of the components during the buffering process and avoids displacement. The elastic pad not only performs secondary buffering, but its outer sealing gasket is always in contact with the mounting plate to ensure a sealing and waterproof effect.

[0016] In this invention, during installation, the installation components are engaged with the trapezoidal clips and slots to achieve rapid assembly of the device and the wall panel, improving construction efficiency. The overall structure is reasonably designed, with good buffering and sealing / waterproofing performance, extending the service life of the wall panel and improving the safety of the building.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a sealing and waterproof buffer device for the joints of prefabricated building wall panels, including a fixing plate 1;

[0025] The buffer assembly 2 includes several springs 201, which are fixedly connected to the opposite side of the fixed plate 1. Push plates 202 are fixedly connected to the opposite side of the springs 201. Two fixed brackets 203 are fixedly connected to the opposite side of the push plates 202. A fixed rod 204 is fixedly connected to the side of the two fixed brackets 203 that are close to each other. A rotating block 205 is rotatably connected to the side surface of the fixed rod 204. A support plate 206 is fixedly connected to one side of the rotating block 205. When the wall panel body 9 is subjected to external impact or temperature change and expands or contracts, the impact force or expansion force will be transmitted to the mounting plate 601. The mounting plate 601 transmits the force to the push plate 202 and the springs 5. The springs 5 ​​first undergo elastic deformation to buffer the initial force. At the same time, the push plate 202 is compressed and squeezes the springs 201. The springs 201 further deform and generate a reverse elastic force, which, together with the springs 5, forms a double buffer structure, effectively reducing the impact of external force on the wall panel joints.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the limiting component 3 includes several limiting frames 301, which are fixedly connected to the opposite side of the fixing plate 1. Each limiting frame 301 has a limiting groove 302 on its top. The limiting component 3 also includes two sliding rods 303, which are slidably connected inside the limiting grooves 302. A rotating block 304 is fixedly connected to the side surface of each sliding rod 303. One side of the rotating block 304 is fixedly connected to the other side of the support plate 206. The push plate 20... 2. During the movement, the fixed frame 203 on one side drives the fixed rod 204 to move synchronously. The rotating block 205 on the fixed rod 204 pushes the support plate 206. The other end of the support plate 206 drives the slide rod 303 to slide in the limiting groove 302 of the limiting frame 301 through the rotating block 304. The limiting groove 302 restricts the movement trajectory of the slide rod 303. Thus, the support plate 206, rotating block and other components ensure that the push plate 202 moves in a fixed direction, so as to avoid the buffer assembly 2 being deflected by force and affecting the buffering effect.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, two limiting blocks 4 are fixedly connected to one side of the fixed plate 1 opposite to each other. Several springs 5 ​​are fixedly connected to one side of the fixed plate 1 opposite to each other. An installation assembly 6 is provided on the outer side of the fixed plate 1. The installation assembly 6 includes two installation plates 601, which are respectively provided on one side and the other side of the fixed plate 1. The side of the installation plates 601 that is close to each other is fixedly connected to several push plates 202 and the side of the springs 5 ​​opposite to each other. Two limiting blocks 602 are fixedly connected to the side of the two installation plates 601 that is close to each other. The outer side of the second limiting block 602 is slidably connected to the outer side of the second limiting block 602. Trapezoidal locking blocks 603 are fixedly connected to the opposite sides of the two mounting plates 601 respectively. First, the device is assembled with the wall panel body 9 through the mounting component 6. The trapezoidal locking blocks 603 on the mounting plate 601 are aligned with the slots 10 on the wall panel body 9 and locked in, so as to realize the quick fixation of the mounting plate 601 and the wall panel body 9. At this time, the two wall panel bodies 9 are symmetrically distributed on both sides of the fixing plate 1 through the mounting plate 601, and the initial installation and positioning of the device is completed.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, elastic pads 7 are fixedly connected to the opposite sides of the two limiting blocks 4, and sealing pads 8 are fixedly connected to the opposite sides of the two elastic pads 7. Wall panel bodies 9 are respectively provided on the opposite sides of the two mounting plates 601. The opposite sides of the wall panel bodies 9 are respectively provided with slots 10. The inside of the slots 10 engages with the outside of the trapezoidal block 603. The sealing pads 8 on the outside of the elastic pads 7 are always tightly fitted with the mounting plates 601 to ensure the sealing performance of the wall panel joints and prevent moisture from seeping in. Through the synergistic effect of the buffer, limiting and sealing structures, the joints of the prefabricated building wall panels are effectively protected.

[0029] The method of use and advantages of this utility model: The sealing and waterproof buffer device for the joints of prefabricated building wall panels works as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the device is first assembled with the wall panel body 9 by installing component 6. The trapezoidal locking block 603 on the mounting plate 601 is aligned with the locking groove 10 on the wall panel body 9 and inserted, achieving quick fixation of the mounting plate 601 and the wall panel body 9. At this time, the two wall panel bodies 9 are symmetrically distributed on both sides of the fixing plate 1 through the mounting plate 601, completing the initial installation and positioning of the device. When the wall panel body 9 is subjected to external impact or temperature change, the impact force or expansion force will be transmitted to the mounting plate 601. The mounting plate 601 transmits the force to the push plate 202 and the second spring 5 respectively. The second spring 5 first undergoes elastic deformation to buffer the initial force. At the same time, the push plate 202 is compressed and squeezes the first spring 201. The first spring 201 further deforms and generates a reverse elastic force, which, together with the second spring 5, forms a double buffer structure, effectively reducing the impact of external force on the wall panel joint. During the movement of the push plate 202, the fixing bracket 203 on one side drives the fixing rod 204 to move synchronously, fixing the wall panel. The rotating block 205 on rod 204 pushes the support plate 206. The other end of the support plate 206 drives the sliding rod 303 to slide in the limiting groove 302 of the limiting frame 301 through the rotating block 304. The limiting groove 302 restricts the movement trajectory of the sliding rod 303, thereby ensuring that the push plate 202 moves in a fixed direction through the support plate 206, rotating block and other components, avoiding the buffer component 2 from being deflected by force and affecting the buffering effect. At the same time, the limiting block 602 on the mounting plate 601 slides along the limiting block 4 on the fixed plate 1, further improving the stability of the movement of the mounting plate 601. The elastic pad 7 on the limiting block 4 plays a secondary buffering role when the mounting plate 601 moves to the limit position, reducing rigid collisions between components. The sealing pad 8 on the outside of the elastic pad 7 is always in close contact with the mounting plate 601, ensuring the sealing performance of the wall panel joint and preventing water seepage. Through the synergistic effect of the buffering, limiting and sealing structure, the effective protection of the wall panel joint of the prefabricated building is achieved.
