Description

Technical Field

[0001] This utility model relates to the field of partition wall technology, and in particular to a device for reinforcing and preventing cracks in partition wall joints. Background Technology

[0002] Due to their advantages such as convenient installation, light weight, and high space utilization, partition walls are widely used in residential, commercial buildings, and industrial plants. Traditional partition wall installation often involves simply splicing the panels and then applying cement mortar or sealant to the joints. This process is prone to cracking at the joints due to multiple factors during long-term use, which can lead to problems such as reduced sound insulation, water seepage, and damage to the appearance, increasing the cost of later maintenance.

[0003] To address this issue, patent CN208347055U discloses a crack-resistant lightweight partition wall panel, primarily solving the problem of insufficient stability in the connection between two partition wall panels in existing technologies, leading to misalignment and cracking of the mortar at the joint. This crack-resistant lightweight partition wall panel includes a partition wall panel body. One side of the partition wall panel body has symmetrically arranged assembly grooves, and the side of the two assembly grooves that are close to each other has a first semi-groove. The other side of the partition wall panel body has symmetrically arranged assembly protrusions. Through this solution, the present invention achieves the goal of locking the post into the first groove, and under the elastic force of the second spring, ensuring that the post is always tightly locked in the first groove. This allows for a tight connection and reinforcement between the assembly grooves and the assembly protrusions, enhancing the stability of the connection between the two partition wall panel bodies, preventing misalignment, and thus avoiding cracking of the mortar at the joint. The operation is simple.

[0004] The crack-resistant lightweight partition wall panel mentioned above is fixed in use by the fitting of the assembly groove and the assembly protrusion and the rigid locking of the spring-driven locking post. However, the locking effect of the spring locking post is weak in actual use, the contact area between the locking post and the first groove is limited, and the elasticity of the spring will decrease due to fatigue with long-term use, resulting in a decrease in locking force. Utility Model Content

[0005] The purpose of this invention is to provide a crack-resistant reinforcement device for partition wall joints, which can solve the problem of insufficient connection stability of existing crack-resistant lightweight partition wall panels.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a partition wall joint anti-crack reinforcement device, comprising a first plate;

[0007] A second plate is mounted on one side of the first plate. Both the first and second plates have through holes. A first connector is mounted on the side of the first plate away from the second plate, and a second connector is mounted on the side of the second plate away from the first plate. A connecting structure is provided between the first and second plates. The connecting structure includes a first groove on one side of the first plate, the second plate, and the first connector. A first protrusion is fixed at the bottom of the first groove. A second groove is provided on the other side of the first plate, the second plate, and the second connector. A second protrusion is fixed at the top of the second groove. A stud is fixed at one end of both the first and second protrusions. A through groove is provided on one side of both the first and second protrusions. A nut is mounted on the outer side of the top of the stud.

[0008] Reinforcing structures are installed on both sides between the first plate and the second plate.

[0009] Preferably, both the first groove and the second groove are semi-circular grooves, and both the first protrusion and the second protrusion are cylindrical.

[0010] With the above structure, during use, the arc-shaped surface of the cylindrical protrusion and the arc-shaped contact surface of the semi-circular groove can naturally guide the protrusion to slide into the groove during installation. The arc-shaped contact surface can also evenly distribute the extrusion and tension loads between the plates to the entire contact area, preventing the protrusion from breaking or the groove from being damaged due to excessive local stress, thereby ensuring the long-term stability of the connection structure.

[0011] Preferably, the outer side of the first protrusion engages with the inner side of the second groove, the outer side of the second protrusion engages with the inner side of the first groove, and one end of the second protrusion abuts against one end of the first protrusion.

[0012] With the above structure, during use, the first protrusion is embedded in the second groove of the second plate, and the second protrusion is embedded in the first groove of the first plate, forming "lateral constraints" from both sides of the plate. This prevents the two plates from shifting left and right due to external forces such as vibration and impact, and prevents the end of the second protrusion from abutting against the end of the first protrusion. After the two plates are joined, a "longitudinal tightening" state is formed, ensuring that the joint is always in a tight fit and reducing cracks caused by the expansion of the gap between the plates.

[0013] Preferably, the outer side of the stud fits into the inside of the through groove, and the first protrusion and the second protrusion are slidably connected to the stud through the through groove.

[0014] With the above structure, the inner wall of the through groove and the outer side of the stud are tightly fitted during use, which can prevent the first protrusion and the second protrusion from wobbling radially during docking or use, and ensure that the protrusion and the groove always remain tightly fitted.

[0015] Preferably, the nut and the stud are threaded together, and the stud is fixedly connected to the first protrusion and the second protrusion respectively by the nut.

[0016] With the above structure, when the nut is tightened along the stud during use, the stud transmits the clamping force evenly to the first protrusion and the second protrusion through the inner wall of the through groove, thereby causing the first plate and the second plate to fit tightly together.

[0017] Preferably, the reinforcing structure includes a sealing groove disposed between the first plate, the second plate, the first connector, and the second connector. A reinforcing plate is installed on one side of the sealing groove, and a sealing block is fixed on one side of the reinforcing plate inside the sealing groove. Mounting holes are provided on both sides of the first plate, the second plate, the first connector, and the second connector, and mounting bolts are installed inside the sealing groove and the mounting holes.

[0018] Preferably, the reinforcing plates are symmetrically distributed on both sides between the first plate, the second plate, the first connector, and the second connector. The sealing block of the reinforcing plates is made of silicone sealant. The mounting holes are equally spaced on both sides of the first plate, the second plate, the first connector, and the second connector. The mounting bolts correspond one-to-one with the mounting holes and are threadedly connected to the mounting holes.

[0019] With the above structure, the silicone sealant has excellent flexibility and adhesion during use, which can tightly fill the tiny gaps in the sealing groove to form a continuous and gapless sealing layer. It also has good elastic recovery. When the partition wall panel undergoes slight deformation due to temperature changes or slight building settlement, the sealant can absorb the deformation stress through its own tension or compression, avoiding the stress from acting directly on the joint filling layer or rigid connection structure.

[0020] The present invention provides a wall panel joint crack prevention and reinforcement device, the advantages of which are:

[0021] By setting up a connecting structure, through the interlocking of protrusions and grooves, and the rigid fixation of studs and nuts, the relative displacement between the first plate and the second plate is limited, thereby reducing the risk of joint cracking caused by vibration and settlement from the structural source.

[0022] By incorporating a reinforced structure and using silicone sealant in the sealing blocks, the system can fill tiny gaps and absorb stress generated by the thermal expansion and contraction of the plate, preventing stress concentration and cracks. This creates a dual crack-resistant protection of "rigid fixation and flexible buffering." Furthermore, the reinforcement plate, through the cooperation of mounting bolts and mounting holes, forms an external clamp at the joint, further enhancing the connection strength between the plate and the connectors and improving the overall structure's resistance to deformation.

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.

[0030] Please see Figures 1-5 The present invention provides a partition wall joint anti-crack reinforcement device, which includes a first plate body 1.

[0031] Reference Figures 2-5As shown, a second plate 2 is installed on one side of the first plate 1. Both the first plate 1 and the second plate 2 have through holes 3 inside. A first connector 4 is installed on the side of the first plate 1 away from the second plate 2, and a second connector 5 is installed on the side of the second plate 2 away from the first plate 1. A connecting structure 6 is provided between the first plate 1 and the second plate 2. The connecting structure 6 includes a first groove 601 on one side of the first plate 1, the second plate 2, and the first connector 4. A first protrusion 602 is fixed to the bottom end of the first groove 601. A second groove 603 is provided on the other side of the first plate 1, the second plate 2, and the second connector 5. A second protrusion 604 is fixed to the top end of the second groove 603. A stud 605 is fixed to one end of both the first protrusion 602 and the second protrusion 604. The first protrusion 602 and the first connector 4 are connected together. Each of the two protrusions 604 has a through groove 606 on one side inside. A nut 607 is installed on the outer side of the top of the stud 605. The first groove 601 and the second groove 603 are both semi-circular grooves. The first protrusion 602 and the second protrusion 604 are both cylindrical. The outer side of the first protrusion 602 fits into the inner side of the second groove 603, and the outer side of the second protrusion 604 fits into the inner side of the first groove 601. One end of the second protrusion 604 abuts against one end of the first protrusion 602. The outer side of the stud 605 fits into the inside of the through groove 606. The first protrusion 602 and the second protrusion 604 are slidably connected to the stud 605 through the through groove 606. The nut 607 is threadedly connected to the stud 605. The stud 605 is fixedly connected to the first protrusion 602 and the second protrusion 604 through the nut 607.

[0032] The first protrusion 602 on one side of the first plate 1 is embedded into the second groove 603 on one side of the second plate 2, while the second protrusion 604 on one side of the second plate 2 is embedded into the first groove 601 on one side of the first plate 1. During the docking process of the first plate 1 and the second plate 2, the stud 605 can slide into the interior of the first protrusion 602 and the second protrusion 604 respectively along the through groove 606. Then, the nut 607 is threadedly connected to the stud 605 and tightened, which will firmly fix the first protrusion 602 and the second protrusion 604, thereby forming a rigid connection between the first plate 1 and the second plate 2, restricting the relative displacement of the two plates, and preventing the joint from cracking due to vibration, settlement and other factors.

[0033] Reference Figures 1-4As shown, reinforcing structures 7 are installed on both sides between the first plate 1 and the second plate 2. Each reinforcing structure 7 includes a sealing groove 701 disposed between the first plate 1, the second plate 2, the first connector 4, and the second connector 5. A reinforcing plate 702 is installed on one side of the sealing groove 701, and a sealing block 703 is fixed to one side of the reinforcing plate 702 inside the sealing groove 701. Mounting holes 704 are provided on both sides of the first plate 1, the second plate 2, the first connector 4, and the second connector 5. Mounting bolts 705 are installed inside the mounting holes 704. The reinforcing plates 702 are symmetrically distributed on both sides between the first plate 1, the second plate 2, the first connector 4, and the second connector 5. The sealing block 703 of the reinforcing plates 702 is made of silicone sealant. The mounting holes 704 are equally spaced on both sides of the first plate 1, the second plate 2, the first connector 4, and the second connector 5. The mounting bolts 705 correspond one-to-one with the mounting holes 704 and are threadedly connected to the mounting holes 704.

[0034] By filling the sealing groove 701 between the first plate 1, the second plate 2, the first connector 4, and the second connector 5 with a sealing block 703, the sealing block 703 is made of silicone sealant, which has good elasticity and sealing properties. It can fill the tiny gaps at the joint and absorb the stress generated by the thermal expansion and contraction of the plate, thus avoiding stress concentration that could lead to cracking. The reinforcing plate 702 is then attached to the outside of the sealing groove 701. The mounting bolts 705 are passed through the holes in the reinforcing plate 702 and the mounting holes 704 on the plate and tightened, so that the reinforcing plate 702 forms an "external clamp" at the joint, further enhancing the stability of the overall structure.
