Description

Technical Field

[0001] This invention relates to the field of waterproof gypsum board technology, specifically to a high-strength waterproof gypsum board. Background Technology

[0002] In the field of building decoration, gypsum board is widely used due to its advantages such as light weight, good fire resistance, and easy processing. However, the suitability of ordinary gypsum board in humid environments has always been a significant technical shortcoming, the core issue of which lies in the waterproofing treatment of the joints between boards.

[0003] Patent publication number CN217782567U relates to the field of waterproof gypsum board technology, including a waterproof board with a protective device on its surface. The protective device includes a cover plate slidably connected to the surface of the waterproof board, a fixing plate fixedly connected to one side of the cover plate, an insert rod slidably passing through the surface of the fixing plate, a baffle plate fixedly connected to the surface of the waterproof board, and a circular groove formed on the side of the baffle plate near the insert rod, the size of the circular groove matching the size of the insert rod. Two sliding grooves are formed on both sides of the waterproof board, and two sliders are fixedly connected to the lower surface of the cover plate, the size of the sliders matching the size of the sliding grooves. This application achieves the effect of covering the gaps between the waterproof boards through the protective device, preventing water from seeping into the interior of the waterproof board through the gaps, thus improving the waterproofness of the waterproof gypsum board.

[0004] The aforementioned patents prevent water from seeping into the interior of the waterproof gypsum board through the gaps between the boards, thus improving its waterproofness. However, these waterproofing measures rely heavily on static sealing materials or post-construction grouting, which has significant shortcomings in practical use. These types of gypsum boards cannot achieve automatic sealing during splicing; gaps between boards and internal cavities may still be exposed. When exposed to water or humid air, moisture can easily seep into the board through the joints. This not only causes the gypsum board core layer to soften and lose strength due to moisture, but may also cause the internal filling material to absorb water and swell, leading to board deformation, warping, and even mold growth. Furthermore, prolonged moisture retention will gradually corrode the internal metal components, reducing their support and durability, severely impacting the service life and structural safety of the gypsum board in humid environments. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a high-strength waterproof gypsum board, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-strength waterproof gypsum board, comprising an upper board and a lower board, wherein the waterproof gypsum board further comprises:

[0007] The filling layer is fixedly installed on the bottom inner wall of the lower plate;

[0008] Insert block, fixedly installed at the bottom of the upper plate;

[0011] A waterproof device for sealing the filler layer is installed on the inner wall of the lower plate;

[0012] The waterproof device can switch between a first state and a second state. In the first state, the sliding block moves towards the upper plate to seal the gap between the upper plate and the lower plate. In the second state, the sliding block is inside the lower plate to prevent the upper plate and the lower plate from being spliced ​​together.

[0013] A splicing device for joining one plate to another is installed on the outer wall of the lower plate;

[0014] A limiting device used to control whether the splicing device extends is installed on the outer wall of the lower plate.

[0015] According to the above technical solution, the waterproof device includes:

[0016] The sliding block is slidably installed on the inner wall of the lower plate;

[0017] The pin is fixedly installed on the side of the upper plate near the sealing plate.

[0018] The sealing plate has a round hole on the side near the pin, and a spring is provided between the sealing plate and the lower plate.

[0019] The technical effect of adopting the above-mentioned further solution is that the insert will push the sliding block to move away from the sealing plate 1. The movement of the sliding block will drive the pin to move. The movement of the pin will release the limit on the sealing plate 1. Then the sealing plate 1 will be pushed by the spring 1 to move towards the inside of the upper plate.

[0020] According to the above technical solution, the waterproof device further includes:

[0021] The sliding key is slidably installed on the inner wall of the upper plate.

[0023] The technical effect of adopting the above-mentioned further solution is that when the position of the fixing groove one coincides with the sliding key, the sliding key will move inward to limit the sealing plate one.

[0024] According to the above technical solution, the waterproof device includes:

[0025] The upper fixing plate is fixedly installed on the top inner wall of the upper plate;

[0026] The lower fixing plate is fixedly installed on the bottom inner wall of the lower plate;

[0030] The technical effect of adopting the above-mentioned further solution is that when the moving pin moves, the sealing plate two will contact the inclined surface of the sliding pin, so the sliding pin cannot limit the sealing plate two. Then the sealing plate two will be pushed downward by the spring three. The downward movement of the sealing plate two will seal the gap between the upper fixed plate and the lower fixed plate.

[0031] According to the above technical solution, the splicing device includes:

[0032] A round pin is fixedly installed at the bottom of the sealing plate, and the round pin slides through the bottom of the inner wall of the lower plate.

[0033] A sliding rod is slidably installed on the inner wall of the lower plate. A circular groove is provided on the top of the sliding rod, and the shape of the circular pin matches the circular groove.

[0034] The slider is slidably mounted on the bottom inner wall of the lower plate.

[0035] The rotating rod is rotatably mounted on the bottom inner wall of the lower plate;

[0036] The fixed block is slidably installed on the bottom of the inner wall of the lower plate;

[0037] The slider has an inclined surface on the side near the sliding rod, and a tension spring is provided between the sliding rod and the lower plate.

[0038] The technical effect of adopting the above-mentioned further solution is that the movement of the round pin will release the limit on the sliding rod, and then the sliding rod will be pulled by the tension spring to move inward towards the lower plate.

[0040] The outer plate is slidably mounted on the inner wall of the lower plate on the side away from the sliding rod;

[0041] The inner panel is slidably installed on the inner wall of the outer panel;

[0042] A sliding stop lever is slidably installed on the inner wall of the inner panel.

[0045] The technical effect of adopting the above-mentioned further solution is that the movement of the round pin will release the restriction between the outer plate and the inner plate, and the outer plate will be pushed by the thrust spring to move outward of the lower plate. When the position of the sliding stop bar coincides with the positioning groove, the sliding stop bar will move inward of the positioning groove to limit the inner plate.

[0046] According to the above technical solution, the splicing device further includes:

[0047] The skateboard is slidably mounted on the inner wall of the upper board near the outer board.

[0048] The telescopic board is slidably installed on the inner wall of the skateboard.

[0051] The technical effect of adopting the above-mentioned further solution is as follows: when the sealing plate moves upward, it will contact the inclined surface of the slide plate, and the sealing plate will push the slide plate out. The movement of the slide plate will push the telescopic plate to move, and the movement of the slide plate will drive the positioning block to move. When the positioning block moves, the upper plate's limitation on the positioning block will be released, and the telescopic plate can move away from the slide plate.

[0052] According to the above technical solution, the splicing device further includes:

[0053] The slide plate is slidably installed on the inner wall of the upper plate on the side away from the skateboard.

[0054] The positioning key is slidably mounted on the inner wall of the sleeve.

[0055] The side of the sleeve plate closest to the sealing plate is set as an inclined surface, and the side of the positioning key away from the sealing plate is set as an inclined surface.

[0056] The technical effect of adopting the above-mentioned further solution is that when the sealing plate moves upward, it will contact the inclined surface of the sleeve plate, and the sealing plate will push the sleeve plate to move away from the upper plate. The movement of the sleeve plate will drive the positioning key to move.

[0057] According to the above technical solution, the limiting device includes:

[0058] The baffle is slidably installed on the inner wall of the upper plate;

[0059] The slide bar is slidably mounted on the inner wall of the upper plate;

[0060] A connecting rod, one end of which is rotatably connected to a sliding rod, and the other end of which is rotatably connected to a baffle;

[0061] A fixed rod is slidably installed on the inner wall of the upper plate. A fixing groove is provided on the side of the sliding rod near the fixed rod, and the fixed rod is in contact with the inner wall of the fixing groove.

[0062] The rotating block is rotatably mounted on the inner wall of the upper plate.

[0063] The technical effect of adopting the above-mentioned further solution is as follows: pulling the slide bar upward will pull the connecting rod to move, the connecting rod will move the baffle, and the baffle will block the slide, outer plate and sleeve plate, preventing the slide, outer plate and sleeve plate from moving away from the lower plate.

[0064] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0065] 1. In this invention, the pressure during splicing triggers the insert block to push the sliding block to move and release the limit of the sealing plate one, so that the sealing plate one and the sealing plate two move in sequence, realizing multiple sealing of the splicing gap between the boards and the gap of the internal cavity. This effect of supporting the sealing during splicing can effectively prevent the intrusion of external liquids and fundamentally improve the waterproof performance of gypsum board.

[0066] 2. In this invention, after the two plates are spliced, they can move slightly to prevent them from squeezing each other during expansion. The entire splicing action is automatically triggered by the movement of the sealing plate, which eventually causes the inner plate, telescopic plate, and sleeve plate of the splicing structure to extend automatically, so that the entire splicing structure is ready for splicing. This greatly simplifies the construction operation, eliminates the need for complicated tools or manual adjustment, and achieves quick installation that is ready to use immediately after splicing, thus improving construction efficiency and accuracy.

[0067] 3. By releasing the final limit of the sliding stop, small displacements within the design range are allowed between the plates, giving the connection a certain degree of flexibility and stress release capability. This prevents huge internal compressive stress caused by thermal expansion and contraction or structural deformation, thereby avoiding plate warping, cracking or damage to the connection point, and improving the overall durability and safety of the structure.

[0068] 4. In this invention, the baffle directly blocks the sliding plate, outer plate, and sleeve plate, fundamentally locking the core moving parts of the splicing device and ensuring that they will not accidentally extend due to vibration or collision during handling and transportation. This effectively prevents the delicate and relatively fragile splicing mechanism from being bumped, damaged, or contaminated during transportation, protecting the integrity and functionality of the equipment.

[0080] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0081] Please see Figures 1-9 One embodiment of the present invention is: a high-strength waterproof gypsum board, comprising an upper board 1, a lower board 2, a filling layer 3, an insert block 4, and a sealing plate 7, the high-strength waterproof gypsum board further comprising:

[0082] The filling layer 3 is fixedly installed on the bottom of the inner wall of the lower plate 2, the insert block 4 is fixedly installed on the bottom of the upper plate 1, and the sealing plate 7 is slidably installed on the inner wall of the upper plate 1.

[0083] The lower plate 2 has a slot on its inner wall, and the insert 4 contacts the inner wall of the slot. The filling layer 3 includes an adhesive and a support column. The support column is slidably installed at the bottom of the inner wall of the lower plate 2. The adhesive is attached to the inner wall of the lower plate 2. In this embodiment, it should be noted that the adhesive is a commercially available conventional adhesive, such as Saint-Gobain Gelco sealant, which can be selected according to the usage requirements. It will not be elaborated here.

[0084] A waterproof device for sealing the filling layer 3 is installed on the inner wall of the lower plate 2.

[0085] The waterproof device can switch between a first state and a second state. In the first state, the sliding block 5 moves toward the upper plate 1 to seal the gap between the upper plate 1 and the lower plate 2. In the second state, the sliding block 5 is inside the lower plate 2 to prevent the upper plate 1 and the lower plate 2 from being spliced ​​together.

[0086] A splicing device for joining one plate to another is installed on the outer wall of the lower plate 2.

[0087] A limiting device for controlling whether the splicing device extends is installed on the outer wall of the lower plate 2.

[0088] In this embodiment, the waterproof device includes a sliding block 5, a pin 6, a first sealing plate 7, a sliding key 8, a sliding pin 9, an upper fixing plate 10, a second sealing plate 11, and a lower fixing plate 12.

[0089] The sliding block 5 is slidably installed on the inner wall of the lower plate 2, the pin 6 is fixedly installed on the side of the upper plate 1 near the sealing plate 7, and the sliding key 8 is slidably installed on the inner wall of the upper plate 1.

[0090] Among them, the sealing plate 7 has a round hole on the side near the pin 6, and a spring is provided between the sealing plate 7 and the lower plate 2. The spring is provided to facilitate pushing the sealing plate 7 to move upward.

[0091] It should also be noted that a sliding groove is provided at the bottom of the upper plate 1, and the sealing plate 7 contacts the inner wall of the sliding groove. A fixing groove is provided on the side of the sealing plate 7 near the sliding key 8, and the sliding key 8 contacts the inner wall of the fixing groove. A spring is provided between the sliding key 8 and the upper plate 1. The spring is provided to push the sliding key 8 to move towards the sealing plate 7.

[0092] The upper fixing plate 10 is fixedly installed on the top of the inner wall of the upper plate 1, the lower fixing plate 12 is fixedly installed on the bottom of the inner wall of the lower plate 2, the sealing plate 11 is slidably installed on the outer wall of the upper fixing plate 10, and the sliding pin 9 is slidably installed on the inner wall of the upper fixing plate 10.

[0093] Among them, a spring three is provided between the sealing plate 2 11 and the upper plate 1. The spring three is provided to push the sealing plate 2 11 downward. A spring four is provided between the sliding pin 9 and the upper fixed plate 10. The spring four is provided to push the sliding pin 9 towards the sealing plate 2 11. The sealing plate 2 11 has a groove 1 and a groove 2 on the side near the sliding pin 9. The sliding pin 9 contacts the inner wall of the groove 2. The top of the sliding pin 9 is set as an inclined surface.

[0094] In this embodiment, the upper plate 1 and the lower plate 2 need to be spliced ​​together. When splicing the upper plate 1 and the lower plate 2, a filling layer 3 needs to be first placed on the inner wall of the lower plate 2 so that the upper plate 1 and the lower plate 2 can be fixed by the adhesive in the filling layer 3, and the upper plate 1 and the lower plate 2 can be supported by the fixing posts in the filling layer 3, thus strengthening the support strength of the upper plate 1 and the lower plate 2. When splicing the upper plate 1 and the lower plate 2, the upper plate 1 will press the insert 4 to move inwards towards the lower plate 2. The moving insert 4 will contact the inclined surface of the sliding block 5, and then the insert 4 will push... Sliding block 5 moves away from sealing plate 7. This movement of sliding block 5 causes pin 6 to move, releasing the limiting effect on sealing plate 7. Sealing plate 7 is then pushed by spring 1 towards the interior of upper plate 1. During this movement, sealing plate 7 blocks the gap created when upper plate 1 and lower plate 2 are joined, preventing liquid from the outer wall from entering the interior. As sealing plate 7 moves upward, it contacts the inclined surface of sliding key 8, pushing sliding key 8 towards the upper fixing plate 10. This movement of sealing plate 7 causes the fixing groove 1 to move. When the position of the fixed groove 1 coincides with the sliding key 8, the sliding key 8 will move inward to limit the sealing plate 1 7. When the sliding key 8 moves upward to the fixed plate 10, it will contact the sliding pin 9. The sliding key 8 will then push the sliding pin 9 to move inward to the fixed plate 10. When the sliding pin 9 moves, the sealing plate 2 11 will contact the inclined surface of the sliding pin 9. The sliding pin 9 will then be unable to limit the sealing plate 2 11, and the sealing plate 2 11 will be pushed downward by the spring 3. The downward movement of the sealing plate 2 11 will contact the upper fixed plate 10 and... The gaps between the lower fixed plates 12 are sealed to enhance the sealing effect between the upper plate 1 and the lower plate 2, preventing the filling layer 3 from absorbing external moisture and causing it to expand and corrode internally. The pressure during splicing triggers the insert block 4 to push the sliding block 5 to move and release the limit of the sealing plate 7, so that the sealing plate 7 and the sealing plate 11 move in sequence, achieving multiple sealing of the splicing gaps between the plates and the gaps in the internal cavities. This effect of sealing the support during splicing can effectively prevent the intrusion of external liquids and fundamentally improve the waterproof performance of the gypsum board.

When the position of the sliding stop rod 28 coincides with the positioning groove, the sliding stop rod 28 moves inward toward the positioning groove, limiting the inner plate 27. When the sealing plate 7 moves upward, it will contact the sliding plate 291. When the inclined surfaces of the two plates come into contact, the sealing plate 7 will push the sliding plate 291 out. The movement of the sliding plate 291 will push the telescopic plate 292 to move. The movement of the sliding plate 291 will drive the positioning block 293 to move. The movement of the positioning block 293 will release the limit of the upper plate 1 on the positioning block 293, allowing the telescopic plate 292 to move away from the sliding plate 291. The movement of the telescopic plate 292 will push the positioning block 293 to move away from the sliding plate 291. When the sealing plate 7 moves upward, it will come into contact with the inclined surface of the sleeve plate 294. The sealing plate 7 will then push the sleeve plate 294 to move away from the upper plate 1. The movement of the sleeve plate 294 will drive the positioning key 295 to move. When it is necessary to splice the two plates, the inner plate 27 of the other plate needs to come into contact with the sliding rod 22 of this plate, so that the inner plate 27. Pushing the sliding rod 22 towards the interior of the lower plate 2, the sliding rod 22 will contact the inclined surface of the slider 23, thus pushing the slider 23 to move. The movement of the slider 23 will push the rotating rod 24 to rotate, and the rotation of the rotating rod 24 will push the fixing block 25 towards the inner plate 27. The fixing block 25 will then insert into the push groove to fix the inner plate 27. When the inner plate 27 is connected to the sliding rod 22, the telescopic plate 292 will connect with the interior of the sleeve plate 294. When the telescopic plate 292 moves towards the interior of the sleeve plate 294, it will push the positioning key 295 to move upward. The movement of the telescopic plate 292 will drive the square groove to move. When the position of the square groove coincides with the positioning key 295, the positioning key 295 will move downward and insert into the square groove, limiting and fixing the sleeve plate 294 and the telescopic plate 292. The movement of block 25 pushes the sliding stop 28 away from the outer plate 26, thus releasing the limit of the sliding stop 28 on the inner plate 27. After the panels are assembled, they can move slightly, preventing them from squeezing each other during expansion. The entire assembly process is automatically triggered by the movement of sealing plate 7, ultimately causing the inner plate 27, telescopic plate 292, and sleeve plate 294 of the assembly structure to extend automatically, preparing the entire assembly structure for splicing. This greatly simplifies construction operations, eliminating the need for complex tools or manual adjustments, enabling quick and easy installation, and improving construction efficiency and accuracy. The final release of the sliding stop 28's limit allows for small displacements within the design range between the panels, providing the connection with a certain degree of flexibility and stress release capability.This design prevents excessive internal compressive stress caused by thermal expansion and contraction or structural deformation, thus avoiding warping, cracking, or damage to joints in the panels and improving the overall durability and safety of the structure.

[0106] When the upper plate 1 and lower plate 2 need to be transported to another location after being assembled, the slide rod 33 needs to be pulled upwards. The upward movement of the slide rod 33 will pull the connecting rod 32, which in turn will move the baffle 31. The baffle 31 will then block the slide plate 291, outer plate 26, and sleeve plate 294, preventing them from moving away from the lower plate 2. After the slide rod 33 moves, it pushes the fixing rod 34 to insert into the slide rod 33, limiting its movement and preventing it from moving downwards during transport. After the fixing rod 34 fixes the slide rod 33, the rotating block 35 will rotate downwards. The downward rotation of the moving block 35 limits the fixed rod 34, preventing it from disengaging from the sliding rod 33 during transportation. When the sliding plate 291 and the sleeve plate 294 cannot extend, they block the sealing plate 7, preventing it from moving inwards towards the upper plate 1. Consequently, the sealing plate 7 cannot release its constraint on the outer plate 26 and the sliding rod 22, ensuring that the splicing device will not extend when the upper plate 1 and lower plate 2 are assembled and need to be moved. The baffle 31 directly blocks the sliding plate 291, outer plate 26, and sleeve plate 294, fundamentally locking the core moving parts of the splicing device and ensuring that it will not extend accidentally due to vibration or collision during handling and transportation. This effectively prevents the delicate and relatively fragile splicing mechanism from being damaged, bumped, or contaminated during transportation, protecting the integrity and functionality of the equipment.
