A crack-resistant structure for ALC wall panel joints

Abstract

This utility model relates to the field of ALC wall panel technology, specifically to an ALC wall panel joint crack-resistant structure, including a base plate, a top plate, and a limiting groove. A vertical plate is fixedly connected to the top of the base plate, and the top plate is fixedly connected to the end of the vertical plate away from the base plate. A connecting plate is fixedly connected to the side of the top plate near the vertical plate. The connecting plates are symmetrically installed at both ends of the top plate and fixedly connected to the vertical plate near the top plate. The limiting groove is formed inside the top plate and is equidistantly distributed within the top plate. This utility model ensures stability by pushing the fastening plate upwards when the ALC wall panel approaches the vertical plate, and then allowing it to fall back and press the wall panel under the action of a spring. When the joint is subjected to external stress, the stress is transmitted to the buffer plate through the crack-resistant mesh. The buffer spring and damping fluid work together to absorb energy, forming a multi-level buffer mechanism, thereby effectively alleviating stress concentration problems and improving the crack resistance of the joint.

Description

Technical Field

[0001] This utility model relates to the field of ALC wall panel technology, and in particular to an ALC wall panel joint anti-crack structure. Background Technology

[0002] ALC wall panels are widely used in the interior and exterior wall structures of modern buildings due to their lightweight, high strength, and excellent thermal and sound insulation properties. Their prefabrication and assembly method helps improve construction efficiency and building quality, while reducing material consumption and construction costs. ALC wall panels are connected by a joint connection device to form an integral wall structure. The design of the joints directly affects the stability and durability of the wall. To ensure the overall performance of the wall, the crack-resistant structure of the wall panel joints is a key component, ensuring the reliability and service life of the wall panel connections.

[0003] Existing anti-crack structures for wall panel joints lack efficient initial fixing structures, making ALC wall panels prone to shifting or loosening during installation, affecting splicing accuracy and construction efficiency. On the other hand, for stress concentration issues at the joints during use, existing structures typically rely on a single rigid connection, lacking a multi-level buffer mechanism with elastic energy absorption and damping functions. This makes it difficult to effectively absorb and disperse stress from external impacts or structural deformations, easily leading to cracks at the joints and reducing the overall durability and safety of the wall.

[0004] Therefore, this utility model proposes an ALC wall panel joint crack-resistant structure. Utility Model Content

[0005] In order to overcome the problem that the existing anti-crack structure of wall panel joints lacks effective initial fixation, which easily leads to wall panel displacement and loosening during installation, affecting splicing accuracy and efficiency, and that the stress concentration problem at the joints has not been mitigated by multi-level buffering, it is difficult to absorb external impact and deformation stress, which can easily cause cracks and reduce the durability and safety of the wall.

[0006] The technical solution of this utility model is as follows: an ALC wall panel joint crack-resistant structure, including a base plate, a top plate, and a limiting groove; a vertical plate is fixedly connected to the top of the base plate, the top plate is fixedly connected to the end of the vertical plate away from the base plate, a connecting plate is fixedly connected to the side of the top plate near the vertical plate, the connecting plates are symmetrically installed at both ends of the top plate, the connecting plates are fixedly connected to the position of the vertical plate near the top plate, and the limiting groove is opened inside the top plate, the limiting groove is equidistantly distributed inside the top plate.

[0007] Preferably, the base plate, the upright plate, and the top plate are an integrated structure, the connecting plates are symmetrically installed on both sides of the upright plate, and the limiting groove penetrates the top plate.

[0008] Preferably, the base plate has a guide slider slidably connected inside, the guide sliders are equidistantly distributed near both sides of the base plate, the guide sliders pass through the top of the base plate, and a limit block is fixedly connected to the side of the guide slider near the base plate.

[0009] Preferably, the limiting block is slidably connected inside the base plate, and a return spring is fixedly connected to the side of the limiting block away from the guide slider. The return springs are symmetrically installed near both ends of the limiting block, and the end of the return spring away from the limiting block is fixedly connected to the inside of the base plate.

[0010] Preferably, a damping tube is fixedly connected inside the upright plate. The damping tubes are symmetrically and alternately distributed inside the upright plate. A piston rod is slidably connected inside the damping tube. The inside of the damping tube is filled with damping fluid. A buffer spring is sleeved on the outside of the piston rod.

[0011] Preferably, one end of the buffer spring is fixedly connected to the side of the upright plate, and the other end of the buffer spring is fixedly connected to a buffer plate. The buffer plates are symmetrically distributed on both sides of the upright plate. The buffer plates are fixedly connected to the end of the piston rod away from the damping tube. The side of the buffer plate away from the buffer spring is fixedly connected to an anti-crack mesh. The buffer plates and the anti-crack mesh are slidably connected to the outer wall of the connecting plate.

[0012] Preferably, a limiting rod is slidably connected inside the limiting groove, and a fastening plate is fixedly connected to one end of the limiting rod away from the limiting groove. The fastening plate is slidably connected to the outer wall of the connecting plate, and a fastening spring is sleeved on the outer side of the limiting rod. One end of the fastening spring is fixedly connected to the side of the top plate near the vertical plate, and the other end of the fastening spring is fixedly connected to the top of the fastening plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. When the device is ready for use, first, place the entire device in the area to be constructed, and place the outer ALC wall panel on the base plate, aligning it with the upright plate. Then, push the ALC wall panel along the guide slider towards the upright plate. During this process, the ALC wall panel gradually presses against the guide slider, forcing it to move inward into the base plate. When the ALC wall panel is in complete contact with the crack-resistant mesh, the guide slider completely retracts into the base plate, effectively guiding the ALC wall panel. The ALC wall panel achieves initial positioning and splicing fixation, completing the device's positioning preparation.

[0015] 2. During the splicing of the external ALC wall panels, the ALC wall panels continue to move closer to the vertical panel along the base plate, pushing the fastening plate upward. When the ALC wall panels are fully in contact with the crack-resistant mesh, the fastening spring drives the fastening plate downward to press the wall panels, achieving fixation and stable support. Finally, external crack-resistant mortar is injected between the ALC wall panels and the crack-resistant mesh to further enhance the structural stability of the splicing area, completing the splicing operation of the ALC wall panels, improving the fixing effect of the device on the ALC wall panels, preventing displacement and loosening during the splicing process, and thus improving splicing accuracy and construction efficiency.

[0016] 3. During the use of the device, when the joint is subjected to external stress, the stress is transmitted to the buffer plate through the crack-resistant mesh, pushing it to slide along the top plate and connecting plate towards the vertical plate. During the movement, the buffer plate continuously compresses the piston rod and the buffer spring, causing the piston rod to move inside the damping tube. The damping filling liquid flows through the micropores on the piston rod, utilizing the incompressibility of the liquid to create a damping effect, thereby achieving the buffering and absorption of the initial stress. At the same time, the buffer spring further absorbs the residual kinetic energy, slowing down the movement speed of the buffer plate, thus effectively relieving the joint stress and forming a multi-level buffer mechanism with elastic energy absorption and damping functions. This effectively absorbs and disperses the stress caused by structural deformation, achieving the crack resistance effect. Attached Figure Description

[0025] Please see Figures 1-6 This utility model provides a technical solution: an ALC wall panel joint anti-crack structure, including a base plate 1, a top plate 3 and a limiting groove 5; a vertical plate 2 is fixedly connected to the top of the base plate 1, the top plate 3 is fixedly connected to the end of the vertical plate 2 away from the base plate 1, a connecting plate 4 is fixedly connected to the side of the top plate 3 close to the vertical plate 2, the connecting plates 4 are symmetrically installed at both ends of the top plate 3, the connecting plates 4 are fixedly connected to the position of the vertical plate 2 close to the top plate 3, and the limiting groove 5 is opened inside the top plate 3, the limiting groove 5 is equidistantly distributed inside the top plate 3.

[0026] The base plate 1, the vertical plate 2, and the top plate 3 are an integrated structure. The connecting plate 4 is symmetrically installed on both sides of the vertical plate 2, and the limiting groove 5 penetrates the top plate 3. The integrated structure improves the overall structural strength and stability of the device. The symmetrical installation of the connecting plate 4 facilitates multi-point balanced support and component guidance, ensuring uniform stress during the splicing process.

[0027] The base plate 1 has a sliding connection to a guide slider 101. The guide sliders 101 are equidistantly distributed near both sides of the base plate 1. The guide sliders 101 pass through the top of the base plate 1. A limit block 102 is fixedly connected to the side of the guide slider 101 near the base plate 1. The limit block 102 can provide a limiting function during the movement of the guide slider 101 to prevent the guide slider 101 from falling out or excessive displacement, thereby improving the operational stability of the guiding mechanism.

[0028] The limiting block 102 is slidably connected inside the base plate 1. A return spring 103 is fixedly connected to the side of the limiting block 102 away from the guide slider 101. The return spring 103 is symmetrically installed near both ends of the limiting block 102. The end of the return spring 103 away from the limiting block 102 is fixedly connected to the inside of the base plate 1. The return spring 103 forms a controllable rebound mechanism, so that the guide slider 101 can automatically return to its original position after being subjected to force, which is convenient for repeated use.

[0029] A damping tube 201 is fixedly connected inside the vertical plate 2. The damping tubes 201 are symmetrically and alternately distributed inside the vertical plate 2. A piston rod 202 is slidably connected inside the damping tube 201. The inside of the damping tube 201 is filled with damping filling liquid 203. A buffer spring 204 is sleeved on the outside of the piston rod 202. Through the synergistic effect of the damping tube 201 and the buffer spring 204, the stress concentration at the joint of the ALC wall panel can be effectively relieved, and the overall crack resistance of the device can be improved.

[0030] One end of the buffer spring 204 is fixedly connected to the side of the upright plate 2, and the other end of the buffer spring 204 is fixedly connected to the buffer plate 205. The buffer plates 205 are symmetrically distributed on both sides of the upright plate 2. The buffer plates 205 are fixedly connected to the end of the piston rod 202 away from the damping tube 201. The side of the buffer plate 205 away from the buffer spring 204 is fixedly connected to the crack-resistant mesh 206. The buffer plates 205 and the crack-resistant mesh 206 are slidably connected to the outer wall of the connecting plate 4. The crack-resistant mesh 206 enhances the stability and contact area at the joint. The buffer plates 205 can quickly transmit stress to the buffer assembly when the joint is under force.

[0031] A limiting rod 301 is slidably connected inside the limiting groove 5. A fastening plate 302 is fixedly connected to one end of the limiting rod 301 away from the limiting groove 5. The fastening plate 302 is slidably connected to the outer wall of the connecting plate 4. A fastening spring 303 is sleeved on the outer side of the limiting rod 301. One end of the fastening spring 303 is fixedly connected to the side of the top plate 3 near the vertical plate 2, and the other end of the fastening spring 303 is fixedly connected to the top of the fastening plate 302. The fastening plate 302 can move smoothly along the outer wall of the connecting plate 4 under the guidance of the limiting rod 301, thereby achieving reliable pressing and fixing of the ALC wall panel.

[0032] Working principle: According to Figures 1 to 3 As shown, when the device is ready for use, firstly, the entire device is placed in the area to be constructed, and the outer ALC wall panel is placed on the base plate 1, aligned with the upright plate 2. Then, an external force is applied to push the ALC wall panel to slide along the guide slider 101 towards the upright plate 2. During this process, the ALC wall panel gradually presses against the guide slider 101, forcing it to overcome the elastic force of the return spring 103 and move into the interior of the base plate 1. When the ALC wall panel is in complete contact with the crack-resistant mesh 206, the guide slider 101 is completely retracted into the interior of the base plate 1, and the ALC wall panel achieves initial positioning and splicing fixation, completing the device's positioning preparation.

[0033] according to Figures 1 to 6As shown, during the splicing of the external ALC wall panels, the ALC wall panels continue to move closer to the vertical plate 2 along the base plate 1, and push the fastening plate 302 to overcome the elastic force of the fastening spring 303 and move upward along the connecting plate 4. When the ALC wall panel is completely in contact with the crack-resistant mesh 206, under the action of the elastic force of the fastening spring 303, the fastening plate 302 is driven to press down on the wall panel to achieve fixation and stable support. During the movement of the fastening plate 302, the limiting rod 301 slides synchronously in the limiting groove 5 to ensure that the movement range of the fastening plate 302 and the fastening spring 303 is controlled. Finally, external crack-resistant mortar is injected between the ALC wall panel and the crack-resistant mesh 206 to further enhance the structural stability of the splicing area and complete the splicing operation of the ALC wall panels.

[0034] according to Figures 2 to 5 As shown, during the use of the device, when the joint is subjected to external stress, the stress is first transmitted to the buffer plate 205 through the crack-resistant mesh 206, pushing it to slide along the top plate 3 and the connecting plate 4 towards the vertical plate 2. During the movement, the buffer plate 205 continuously compresses the piston rod 202 and the buffer spring 204, causing the piston rod 202 to move within the damping tube 201. The damping filling liquid 203 flows through the micropores on the piston rod 202, utilizing the incompressibility of the liquid to create a damping effect, thereby achieving the buffering and absorption of the initial stress. At the same time, the buffer spring 204 further absorbs the residual kinetic energy, slowing down the movement speed of the buffer plate 205, thus effectively relieving the joint stress and achieving the crack-resistant effect.

[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
