Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of insulation board sealing, and in particular relates to an insulation floor insulation board sealing device. BACKGROUND

[0002] In insulation floor construction, the process precision of insulation board laying directly determines the final insulation performance, and the interval control and gap sealing are key links, which need to be scientifically operated in combination with actual working conditions. In conventional construction, the insulation board gap is controlled in a small range, which can not only reserve a buffer space for thermal expansion and cold contraction of the board, but also can maximize the reduction of heat loss through the gap, and can also take into account the practicability and insulation effect. However, in specific scenarios, such as the presence of protruding structures in the base layer, special specifications of the board need to be adapted, the gap needs to be expanded to a larger interval, and at this time, special measures need to be taken to ensure the rationality of construction. The construction personnel need to select insulation boards with standard compressive strength and encrypt fixed anchor points according to the ground load grade and design insulation index; high-strength insulation mortar is first filled in the gap to ensure that it is dense and free of hollowing, then elastic foam strips are embedded, and finally waterproof sealant is applied, the width of which needs to be appropriately wider than the edge of the gap. Through the double protection of "filling + sealing", the interval requirement is met, and heat conduction and water vapor penetration are blocked, thereby ensuring the insulation of the floor and the stability of the structure.

[0003] For example, the invention with the publication number CN218952674U discloses an insulation floor insulation board sealing device. The insulation floor insulation board sealing device includes a heat preservation structure, the bottom surface of the heat preservation structure is fixed on the surface of the floor through an adhesive layer, the heat preservation structure includes a heat preservation layer, an insulation board, an edge sealing plate, a clamping column and a clamping sleeve, the bottom surface of the insulation board is fixed on the surface of the floor through an adhesive layer, the heat preservation layer is fixed in the interior of the insulation board, and the edge sealing plate is fixed on the two end sidewalls of the insulation board; a sealing structure is installed between the two insulation boards; a capsule breaking structure is installed in the interior of the support rubber pad; and a sealing structure is installed on the top surface of the jointing point of the two insulation boards. The provided insulation floor insulation board sealing device can seal the gap at the jointing point of the insulation boards, and achieves good insulation effect in the room.

[0004] In the prior art, the capsule structure of the knife tool is controlled by extrusion to control the shearing of the glue, so that the glue can overflow and adhere to achieve the effect of sealing, thereby achieving good insulation effect. However, the existing device structure is fixed, but different construction scenes have different installation requirements. If the interval cannot be adjusted, the adaptability and application range of the device will be limited, the flexibility and practicability of use will be greatly reduced, and the individualized installation requirements of different users cannot be met.

[0008] Preferably, the lower trapezoidal platform has arc-shaped grooves on both sides, and the arc-shaped grooves are slidably disposed on the outside of the arc-shaped strip. A limit slider is installed on the side of the lower trapezoidal platform away from the base plate.

[0009] Preferably, the combined teeth are arranged inside the tooth groove, a movable hook frame is installed on the top of the movable rod, and a pressing column is installed on the bottom of the pressing plate.

[0010] Preferably, a linkage cutting assembly is provided below the pressing column; The linkage cutting assembly includes a splicing plate, a locking post is installed at the bottom of the splicing plate, a movable groove is opened on the inner side of the splicing plate, and a downward pressure tooth plate is slidably arranged on the inner side of the movable groove.

[0011] Preferably, a limiting guide rod is installed on the inner side of the lower end of the splicing plate, a sliding sleeve is slidably provided on the outer side of the limiting guide rod, and baffles are installed on both sides of the sliding sleeve. The baffles are arranged on the side of the splicing plate, an adjusting column is installed on the side of the baffle away from the sliding sleeve, and a locking hook is installed at the bottom of the sliding sleeve.

[0012] Preferably, the linkage cutting assembly includes a gear, which is rotatably disposed on the inner side of the splicing plate, and meshes with the back of the lower pressure plate. A rotating rod is installed in the middle of the gear, and the two ends of the rotating rod are bolted together.

[0013] Preferably, a plurality of cutting blades are installed on the outer side of the combined end, and a support frame is fixedly installed on both sides of the splicing plate. The support frame is sleeved on the outer side of the rotating rod, and a filling bladder is provided on the inner side of the support frame.

[0014] Preferably, a support plate is installed on the top of the base plate, the splicing plate assembly is arranged on the top of the support plate, a positioning hole is opened on the top of the support plate, the locking pin assembly is arranged inside the positioning hole, a locking hole is opened on the top of the support plate, and the locking hook is slidably arranged inside the locking hole.

[0015] Preferably, limit guide plates are installed on the top of both ends of the base plate, and a limit groove is opened on the side of the limit guide plate near the lower trapezoidal platform. The limit slider is slidably disposed inside the limit groove. Telescopic plates are installed on both sides of the limit guide plate, and a limit sleeve is slidably disposed on the outer side of the telescopic plate. The telescopic limit sleeve is fixedly installed at both ends of the outward extension plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordination of a pressing and unfolding assembly and a pressing and sealing plate, facilitates the adjustment of the distance between two sets of structures via the pressing action. Furthermore, the use of locking teeth embedded in the side of the insulation board increases the stability of the assembly. Directly controlling the movement of the pressing and sealing plate moves the pressing support and the combining teeth downwards. Because the stop block in the middle of the combining teeth prevents them from moving towards the center, the combining teeth remain within the grooves of the teeth. The pressing action synchronously pushes the pressing trapezoidal platform downwards via the combining teeth. During this downward movement, the pressing trapezoidal platform pushes the inclined platforms on both sides and the outer unfolding plate outwards synchronously through the arc-shaped grooves. During the unfolding process, the locking mechanism on the outer unfolding plate... The locking teeth are inserted into the side of the insulation board. After insertion, the top surface of the locking teeth restricts the expansion of the board structure, preventing it from falling off and increasing the stability of the structure. After expansion, the movable hook frame, movable rod, and stop block are lifted using tools. Once lifted, the middle of the combined teeth will be unrestricted. By continuing to press down on the sealing plate, downward pressure can be applied to the combined teeth through the inclined surface of the tooth groove, thus pushing the sealing plate to move further downward and enabling further operation. The spacing between the two sets of expansion plates can be flexibly adjusted using the downward expansion component. By adjusting the spacing, the spacing of the insulation boards can be adapted to different construction conditions, effectively increasing the adaptability and applicability of the device.

[0017] This invention, through the coordinated arrangement of a linkage cutting component and a pressing sealing plate, facilitates the cutting of the glue-filled structure by continuing to press down, thereby effectively increasing the uniformity of glue filling and improving the cutting effect. The pressing sealing plate lowers the pressing column, pushing the pressing toothed plate into the inner side of the splicing plate. During the pressing process, the pressing toothed plate meshes with and drives the gears to rotate. This rotation drives the rotating rod to rotate synchronously, simultaneously controlling the end assembly and the cutting blade to rotate rapidly. During rotation, the filling bladder located inside the support frame is quickly cut. The moisture in the air quickly comes into contact with the bladder after cutting, resulting in a chemical reaction that fills the internal space. The pressing method allows for rapid control of multiple sets of cutting blades to rotate quickly and evenly cut the filling bladder, exposing the internal glue and achieving the filling of the internal cavity, effectively ensuring the uniformity of the filling.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 9 As shown, the present invention provides a sealing device for thermal insulation boards of thermal insulation flooring, including a base plate 100, and pressing and unfolding components 001 are provided on the top of both ends of the base plate 100. The pressure-down unfolding assembly 001 includes two sets of outward-expanding plates 200. An inclined platform 202 is installed on one side of each end of the outward-expanding plate 200. A pressure-down trapezoidal platform 300 is slidably arranged between the two sets of inclined platforms 202. The pressure-down unfolding assembly 001 includes a pressure-down sealing plate 401. Pressure-down brackets 402 are installed at the bottom of both ends of the pressure-down sealing plate 401. The pressure-down brackets 402 are slidably arranged in the middle of the pressure-down sealing plate 401. Combination teeth 400 are installed on both sides of the lower end of the pressure-down brackets 402. A movable rod 404 is slidably arranged in the middle of the pressure-down brackets 402. A stop block 405 is installed at the bottom of the movable rod 404. The stop block 405 is slidably arranged on the inner side of the lower end of the pressure-down brackets 402.

[0022] Using the above solution: the base plate 100 can provide an installation position for the top structure. The outward adjustment of the outward extension plate 200 can push the locking tooth 201 to insert into the side of the insulation board to achieve a locking effect. By moving the downward trapezoidal platform 300, the inclined platform 202 and the outward extension plate 200 can be pushed outward through the inclined surface. The downward support 402 can drive the combined tooth 400 to adjust the downward trapezoidal platform 300 by pressing down. The movable rod 404 can slide along the inner side of the downward support 402 to change the position of the stop 405. The stop 405 can restrict the combined tooth 400 and prevent the combined tooth 400 from moving towards the center and causing it to disengage from the tooth groove 304.

[0023] like Figure 2- Figure 5 As shown, a number of locking teeth 201 are fixedly installed on the side of the outer extension plate 200 away from the tilting platform 202, and an arc-shaped strip 203 is installed on the side of the tilting platform 202 near the pressing trapezoidal platform 300.

[0024] The trapezoidal platform 300 has arc-shaped grooves 301 on both sides, and the arc-shaped grooves 301 are slidably disposed on the outside of the arc-shaped strip 203. A limit slider 302 is installed on the side of the trapezoidal platform 300 away from the base plate 100. An adjustment groove 303 is provided in the middle of the trapezoidal platform 300, and toothed grooves 304 are provided on both sides of the adjustment groove 303.

[0025] The combined teeth 400 are arranged inside the tooth groove 304, the top of the movable rod 404 is equipped with a movable hook bracket 403, and the bottom of the pressure plate 401 is equipped with a pressure column 406.

[0026] Using the above scheme: the locking tooth 201 has a structure with an upper plane and a lower slope. When extended, the locking tooth 201 will be embedded in the side of the insulation board to achieve a locking effect. The curved strip 203 can guide the tilting platform 202. The curved groove 301 can slide stably along the curved strip 203, thereby greatly increasing the stability of the sliding adjustment. The limiting slider 302 can slide along the inner side of the limiting groove 105. The adjusting groove 303 can limit the sliding of the inner pressing bracket 402. The tooth groove 304 can limit the combined tooth 400. The movable hook frame 403 can use tools to adjust the height of the movable rod 404. The pressing column 406 can adjust the position of the pressing tooth plate 504 by pressing down.

[0027] like Figure 6 and Figure 7 As shown, a linkage cutting component 002 is provided below the pressing column 406; The linkage cutting assembly 002 includes a splicing plate 501, a locking post 502 is installed at the bottom of the splicing plate 501, an active groove 503 is opened on the inner side of the splicing plate 501, and a downward pressing tooth plate 504 is slidably arranged on the inner side of the active groove 503.

[0028] A limiting guide rod 505 is installed on the inner side of the lower end of the splicing plate 501. A sliding sleeve 506 is slidably provided on the outer side of the limiting guide rod 505. Baffles 507 are installed on both sides of the sliding sleeve 506. The baffles 507 are combined and arranged on the side of the splicing plate 501. An adjusting column 508 is installed on the side of the baffle 507 away from the sliding sleeve 506. A locking hook 500 is installed at the bottom of the sliding sleeve 506.

[0029] The linkage cutting assembly 002 includes a gear 601, which is rotatably disposed on the inner side of the splicing plate 501. The gear 601 is meshed on the back of the lower pressure tooth plate 504. A rotating rod 602 is installed in the middle of the gear 601, and the two ends of the rotating rod 602 are bolted to the combined end 603.

[0030] Several sets of cutting blades 600 are installed on the outer side of the combined end 603. Support frames 604 are fixedly installed on both sides of the splicing plate 501. The support frames 604 are sleeved on the outer side of the rotating rod 602. A filling bladder 605 is provided on the inner side of the support frames 604.

[0031] Using the above scheme: the splicing plate 501 is installed on top of the support plate 101 in a combined manner. The locking pin 502, inserted into the inner side of the positioning hole 102, provides lateral restraint. The locking hook 500, inserted into the inner side of the locking hole 103, achieves vertical restraint. The movable groove 503 restrains the inner pressing tooth plate 504, ensuring the pressing tooth plate 504 can stably drive the gear 601 to rotate. The limiting guide rod 505 restrains the outer sliding sleeve 506, increasing the stability of the sliding adjustment. The adjusting pin 508 provides a grip for the user, and adjustment allows the locking hook 500 to move laterally. The baffle 507... The internal adjustment cavity is sealed to prevent glue from entering the adjustment cavity when filling the main cavity, which would make recycling difficult. The gear 601 drives the lower pressure plate 504 to rotate. During the rotation, the rotating rod 602 drives the combined end 603 and the cutting blade 600 to rotate rapidly to cut the filling bag 605. The filling bag 605 is filled with moisture-curing expanding polyurethane adhesive, which will quickly expand and fill the internal cavity when it comes into contact with moisture in the air. Together with the main body's support structure, it can effectively increase the strength. Compared with directly filling with moisture-curing expanding polyurethane adhesive, it can effectively avoid the problem of displacement of the insulation board.

[0032] like Figure 1 and Figure 8 As shown, a support plate 101 is installed on the top of the base plate 100, and a splicing plate 501 is assembled on the top of the support plate 101. A positioning hole 102 is opened on the top of the support plate 101, and a locking pin 502 is assembled inside the positioning hole 102. A locking hole 103 is opened on the top of the support plate 101, and a locking hook 500 is slidably arranged inside the locking hole 103.

[0033] Limiting guide plates 104 are installed on the top of both ends of the base plate 100, and a limiting groove 105 is opened on the side of the limiting guide plate 104 near the lower trapezoidal platform 300. The limiting slider 302 is slidably disposed inside the limiting groove 105. Telescopic plates 106 are installed on both sides of the limiting guide plate 104, and a limiting sleeve 107 is slidably disposed on the outer side of the telescopic plate 106. The telescopic limiting sleeve 107 is fixedly installed at both ends of the outer extension plate 200.

[0034] Using the above solution: the support plate 101 can provide support for the top structure, the positioning hole 102 can provide assembly space for the locking post 502, the locking hole 103 can restrict the locking hook 500, the limiting guide plate 104 and the limiting slide 105 can restrict the downward trapezoidal platform 300, so that the downward trapezoidal platform 300 can only make stable up and down movement adjustment, and the telescopic plate 106 and the limiting sleeve 107 can close the side area of ​​the outer extension plate 200 to maintain the stability of the structure.

[0035] The working principle and usage process of this invention are as follows: The device is placed between two sets of insulation boards, and the lower pressure sealing plate 401 and lower pressure bracket 402 are directly pushed downwards. During this movement, the combined teeth 400 transmit force to the lower pressure trapezoidal platform 300 within the tooth groove 304, controlling the lower pressure trapezoidal platform 300 and the limiting slider 302 to vertically adjust along the limiting slide groove 105. During adjustment, the lower pressure trapezoidal platform 300 will compress the two sets of inclined platforms 202 and the outer expansion plate 200, causing them to expand outwards simultaneously. During expansion, the telescopic plate 106 moves synchronously along the inner side of the limiting sleeve 107. During the expansion of the outer expansion plate 200, the locking teeth 201 will embed into the insulation board. On the inside of the plate, the movable rod 404 and the stop block 405 are moved upward using a tool. Then, downward pressure is applied to control the movement of the pressure sealing plate 401 and the pressure column 406. During the movement, the tooth groove 304 will move the extrusion combination tooth 400 towards the center until it completely passes through the pressure trapezoidal platform 300. The pressure column 406 will push the pressure tooth plate 504 to move. During the movement, the tooth block will mesh with the transmission gear 601 and the rotating rod 602 to rotate. Finally, the cutting blade 600 at the end will rotate rapidly to cut the protruding area of ​​the filling bladder 605. The moisture-curing expansion polyurethane adhesive inside will expand rapidly after contacting the moisture in the outside air and fill the internal space.
