Description

Technical Field

[0001] This utility model belongs to the field of sealing strip technology, specifically relating to the structure of extruded polystyrene board composite sealing strips. Background Technology

[0002] Extruded polystyrene (XPS) board, also known as extruded polystyrene foam board, is a continuous closed-cell foamed rigid plastic board made from polystyrene resin as raw material. After adding other mixtures, the mixture is heated, mixed, and a catalyst is injected, and then extruded. To prevent moisture penetration, XPS board generally requires the installation of sealing strips on its perimeter.

[0003] Existing sealing strips are generally bonded to extruded polystyrene boards with sealant. When removing the sealing strip, it is necessary to pull it off forcefully. This can cause the sealing strip and the extruded polystyrene board to deform due to excessive pulling during the removal process, affecting the reuse of the sealing strip and the extruded polystyrene board. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed extruded board composite sealing strip structure to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] The extruded polystyrene board composite sealing strip structure includes a U-shaped rubber side plate. A partition is fixedly installed in the inner cavity of the rubber side plate. Both ends of the rubber side plate extend to the outside of the partition to form outer clamps. Anti-slip grooves are provided on the adjacent sides of the two outer clamps. A rubber airbag is provided between the two outer clamps. A connecting piece is fixedly connected to the side of the rubber airbag near the partition. The end of the connecting piece away from the rubber airbag is fixed to the partition. Both ends of the rubber airbag are fixedly installed with connecting seats recessed in the inner cavity of the rubber airbag. An inflation tube is fixedly inserted through one of the connecting seats. A one-way valve is installed at the connection between the inflation tube and the connecting seat. An exhaust tube is fixedly inserted through the other connecting seat. An exhaust valve is installed at the connection between the exhaust tube and the connecting seat.

[0007] As a further optimization of this utility model, a rubber rib is horizontally installed between the partition and the inner wall of the rubber side plate, and a reinforcing metal sheet that is fixedly connected to the inner wall of the partition is inserted through the inner cavity of the partition along the length direction of the partition.

[0008] As a further optimization of this utility model, a U-shaped metal skeleton is embedded inside the sidewall of the rubber side plate, and the two ends of the metal skeleton extend into the two outer clamping plates and are fixedly connected to the outer clamping plates.

[0009] As a further optimization of this utility model, a bubble tube is fixedly connected to the outer wall of the rubber side plate above the rubber rib. The bubble tube is hollow inside. A set of arc-shaped elastic support plates is fixedly connected to the inner walls of both sides of the bubble tube. Multiple elastic support plates in each set are equidistantly distributed along the height direction of the bubble tube side wall. Both ends of the elastic support plate are fixedly connected to the side wall of the bubble tube.

[0010] As a further optimization of this utility model, the thickness of the upper and lower sidewalls of the rubber airbag is less than the thickness of the left and right sidewalls of the rubber airbag, and the upper and lower outer walls of the rubber airbag are integrally formed with reverse teeth.

[0011] As a further optimization of this utility model, a connector is fixedly installed at one end of the inflation tube located in the inner cavity of the connecting seat, and the outer surface of the connector is provided with an external thread for connecting with an external inflation device.

[0012] The beneficial effects of this utility model are as follows: In use, the rubber airbag is embedded in the groove opened on the periphery of the extruded board, and air is injected into the rubber airbag through the inflation tube, so that the rubber airbag expands and the inverted teeth squeeze and fix the rubber airbag in the groove, thus completing the installation of the entire sealing strip. When it is necessary to disassemble the sealing strip structure, the air in the rubber airbag can be discharged by opening the exhaust valve, and the rubber airbag can be pulled out from the groove. There is no need for hard pulling and squeezing, and it will not cause deformation of the sealing strip structure and the extruded board. Therefore, it does not affect the secondary use of the extruded board of the sealing strip structure. Attached Figure Description

Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example

[0020] like Figure 1 - Figure 4 As shown, the extruded board composite sealing strip structure includes a U-shaped rubber side plate 1, a partition 2 fixedly installed in the inner cavity of the rubber side plate 1, and a rubber rib 3 horizontally installed between the partition 2 and the inner wall of the rubber side plate 1. The rubber rib 3, in conjunction with the partition 2, supports the outer wall of the rubber side plate 1, so as to avoid large deformation of the outer wall of the rubber side plate 1 after being compressed. At the same time, after the rubber side plate 1 is deformed, it can be supported by the rubber rib 3 so that the rubber side plate 1 can be quickly restored.

[0021] A reinforcing metal sheet 4 is provided in the inner cavity of the partition 2 along the length of the partition 2 and is fixedly connected to the inner wall of the partition 2. The reinforcing metal sheet 4 is used to reinforce the partition 2. At the same time, since the reinforcing metal sheet 4 is made of metal, it has good plasticity. Users can bend the rubber side plate 1 at any position and then use the reinforcing metal sheet 4 to maintain the shape of the rubber side plate 1, which is convenient for shaping the overall sealing strip structure.

[0022] The rubber side plate 1 extends to the outside of the partition 2 at both ends to form an outer clamping plate 5. Anti-slip grooves 6 are provided on the adjacent side of the two outer clamping plates 5. The two outer clamping plates 5 are used to clamp the two sides of the extruded board. A U-shaped metal skeleton 7 is embedded in the side wall of the rubber side plate 1. The two ends of the metal skeleton 7 extend into the two outer clamping plates 5 and are fixedly connected to the outer clamping plates 5. By setting the metal skeleton 7, the clamping force of the outer clamping plate 5 on the rubber side plate 1 on the extruded board can be greatly improved. With the anti-slip grooves 6 provided on the outer clamping plate 5, the outer clamping plate 5 can be prevented from slipping off the extruded board after clamping.

[0023] A bubble tube 8 is fixedly connected to the outer wall of the rubber side plate 1 above the rubber rib 3. The bubble tube 8 is hollow inside. A set of arc-shaped elastic support plates 9 are fixedly connected to the inner walls of both sides of the bubble tube 8. Multiple elastic support plates 9 in each set are equidistantly distributed along the height direction of the side wall of the bubble tube 8. Both ends of the elastic support plates 9 are fixedly connected to the side wall of the bubble tube 8. The bubble tube 8 is set to fit the external structure to seal the connection between the extruded board and the external structure. Multiple elastic support plates 9 are installed on the inner wall of the bubble tube 8 to provide support after the bubble tube 8 is deformed by pressure, and to assist the bubble tube 8 in restoring its original position. This is to avoid the problem that the bubble tube 8 cannot be restored after being under pressure for a long time, which would affect the sealing performance.

[0024] A rubber airbag 10 is provided between the two outer clamping plates 5. A connecting piece 11 is fixedly connected to the side of the rubber airbag 10 near the partition plate 2. The end of the connecting piece 11 away from the rubber airbag 10 is fixed to the partition plate 2. The thickness of the upper and lower side walls of the rubber airbag 10 is less than the thickness of the left and right side walls of the rubber airbag 10. The upper and lower outer walls of the rubber airbag 10 are integrally formed with inverted teeth 12. A rubber airbag 10 is provided between the two outer clamping plates 5 and fixed to the partition plate 2 on one side. It is used to insert the rubber airbag 10 into the groove opened on the periphery of the extruded board when installing the overall sealing strip structure.

[0025] Both ends of the rubber airbag 10 are fixedly installed with connecting seats 13 recessed in the inner cavity of the rubber airbag 10. An inflation tube 14 is fixedly inserted through one of the connecting seats 13. A one-way valve 16 is installed at the connection between the inflation tube 14 and the connecting seat 13. A connector 15 is fixedly installed at one end of the inflation tube 14 located in the inner cavity of the connecting seat 13. The outer surface of the connector 15 is provided with external threads for connecting with an external inflation device. When the rubber airbag 10 is inserted into the groove opened on the periphery of the extruded board, the connector 15 can be connected to the external inflation device. Inflation is carried out into the rubber airbag 10 through the inflation tube 14, thereby expanding the rubber airbag 10. The reverse teeth 12 provided on the upper and lower sides of the rubber airbag 10 fix the rubber airbag 10 to the periphery of the extruded board to complete the installation of the overall sealing strip. No adhesive is required, which makes it convenient for users to install the sealing strip.

[0026] An exhaust pipe 17 is fixedly installed on another connecting seat 13. An exhaust valve 18 is installed at the connection between the exhaust pipe 17 and the connecting seat 13. When it is necessary to disassemble the overall sealing strip structure, the user can open the exhaust valve 18 installed on the exhaust pipe 17 to discharge the air filled in the rubber airbag 10. At this time, the volume of the rubber airbag 10 is reduced, and the user can directly pull the rubber airbag 10 out from the groove opened on the periphery of the extruded board to complete the disassembly of the overall sealing strip structure. Since the disassembly process does not require hard pulling and squeezing, it will not cause deformation of the sealing strip structure and the extruded board, so it will not affect the secondary use of the extruded board of the sealing strip structure.

[0027] It should be noted that, in use, the rubber airbag 10 is inserted into the groove on the periphery of the extruded polystyrene board, and then the connector 15 is connected to an external inflation device. Inflation is then carried out through the inflation pipe 14, causing the rubber airbag 10 to expand. This expansion, combined with the inverted teeth 12 on the upper and lower sides of the rubber airbag 10, compresses and fixes the rubber airbag 10 into the groove on the periphery of the extruded polystyrene board, thus completing the installation of the entire sealing strip. No adhesive is required, making it convenient for users to install the sealing strip. When it is necessary to disassemble the sealing strip structure, the user can open the exhaust valve 18 installed on the exhaust pipe 17 to expel the air from the rubber airbag 10. At this time, the volume of the rubber airbag 10 decreases, and the user can directly pull the rubber airbag 10 out of the groove on the periphery of the extruded polystyrene board to complete the disassembly of the entire sealing strip structure. Since the disassembly process does not require hard pulling and squeezing, it will not cause deformation of the sealing strip structure and the extruded polystyrene board, thus not affecting the secondary use of the extruded polystyrene board of the sealing strip structure.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
