It boasts the advantage of high airtightness at the joints between sealing panels, solving the problem that in some grain silos, sealing panels require splicing or overlapping for sealing. After the panels are spliced ​​together, air leakage easily occurs at the gaps and joints, thus affecting the sealing environment inside the grain silo.

[0006] To achieve high airtightness of the joints between the sealing plates, and to prevent the sealing plates from deforming, falling off, or detaching, inert gas can be filled into the grain silo to maintain a certain pressure, kill pests, and keep it warm. This utility model provides the following technical solution: a pressure-resistant, heat-insulating, and airtight indoor wall component for grain silos.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a pressure-resistant, heat-insulating, and airtight interior wall component for grain storage, which has the following beneficial effects:

[0014] This type of pressure-resistant, heat-insulating, and airtight interior wall component for grain storage utilizes a combination of a wall sealing film, a first steel plate, a rigid insulation board, and a second steel plate. The rigid insulation board naturally foams and bonds to both sides of the first and second steel plates. The wall sealing film is then adhered to the surface of the first steel plate using hot air welding. When assembling parallel wall components, expanding foam is first applied to the surface of the second steel plate of one wall component, which is then adhered to the wall. After adhesion, holes are drilled at four designated points, and expansion bolts are used to completely secure the wall component to the wall. The second wall component is then installed, similarly applying expanding foam and inserting pins into the grooves of the first wall component, securing it with expansion bolts. Finally, the wall sealing film of the second wall component extends beyond the coverage area of ​​the first steel plate, covering all the drilled points, and is adhered together using hot air welding. This achieves a high degree of airtightness at the joints between the sealing boards. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-4 A pressure-resistant, heat-insulating, and airtight interior wall component for grain storage includes a wall sealing film 1, a first steel plate 2, a rigid insulation board 3, and a second steel plate 4. The rigid insulation board 3, the first steel plate 2, and the wall sealing film 1 are sequentially bonded to the second steel plate 4. The rigid insulation board 3, made of foamed materials such as polyurethane, EPS, or XPS, is sandwiched between the first steel plate 2 and the second steel plate 4. The rigid insulation board 3 bonds to both sides of the first steel plate 2 and the second steel plate 4 through its own natural foaming and, after a certain period of hardening, acquires a certain strength and rigidity. The first steel plate 2 and the second steel plate 4 are made of 0.3-0.6mm thick steel plates. The presence of the first steel plate 2 and the second steel plate 4 enhances the overall strength and rigidity of the wall component, giving it a longer service life and better pressure resistance. The wall sealing film 1 is made of PVC roll material, which has good airtightness and weldability. When wall components are installed in parallel, the wall sealing film 1 can be applied to the joint between adjacent wall components using hot air welding technology, thereby completely sealing the joint and improving the airtightness of the grain silo. Furthermore, this PVC roll material exhibits very little shrinkage and deformation, with minimal deformation caused by thermal expansion and contraction, preventing loosening and detachment due to prolonged use.

[0022] The wall sealing film 1 has at least one perimeter extending beyond the boundary of the first steel plate 2 to form a covering area. The wall sealing film 1 is adhered to the first steel plate 2. When the wall components are spliced ​​in parallel, the covering area of ​​the wall sealing film 1 extending beyond the boundary of the first steel plate 2 is bonded to the wall components using hot air welding technology, thus covering the gaps between the two wall components and sealing the gaps to enhance airtightness.

[0023] The wall sealing film 1 also has perforation points 5 at its four corners. During the installation of the wall component on the wall, expanding foam is first sprayed onto the surface of the second steel plate 4, and then the entire wall component is adhered to the wall or floor. After drilling the perforation points 5, expansion bolts are installed to further enhance the connection strength between the wall component and the wall surface.

[0024] The distance from the drilling point 5 to the boundary of the first steel plate 2 is less than the distance from which the wall sealing membrane 1 extends beyond the boundary of the first steel plate 2. After drilling at the drilling point 5, expansion bolts are installed to enhance the connection strength between the wall component 2 and the wall / floor. However, after drilling and installing the expansion bolts, a certain degree of airtightness may still exist at the drilling point. Therefore, when the wall component 2 is installed parallel to the first steel plate 2, the area where the wall sealing membrane 1 extends beyond the coverage area of ​​the first steel plate 2 can be covered by hot air welding to cover the drilling point 5, thereby preventing air leakage at the drilling point 5 and solving the airtightness problem.

[0025] One side of the rigid insulation board 3 is equipped with a pin 32, and the other side of the rigid insulation board 3 is equipped with a groove 31. When the wall components are spliced ​​in parallel, the pin 32 is inserted into the groove 31 of the rigid insulation board 3 of the adjacent wall component. During the splicing of wall components, due to the large volume and area of ​​the wall components, precise installation is difficult. Therefore, the pin 32 and groove 31 are used to accurately splice the wall components in pairs. In addition, the use of pin 32 and groove 31 can increase the integrity and continuity between all wall components, and improve the overall strength of the wall components. Furthermore, the use of pin 32 and groove 31 can improve airtightness.

[0026] Vertical edging 21 is provided on the longer side of the first steel plate 2 and the second steel plate 4. The edging 21 of the first steel plate 2 and the second steel plate 4 can protect the integrity of the internal rigid insulation board 3. In addition, the edging 21 makes the three-dimensionality of the entire wall component better, the installation more precise, the connection between the wall components tighter, the airtightness better improved, and the compressive strength also higher.

[0027] Working principle: The rigid insulation board 3 naturally foams and bonds to the first steel plate 2 and the second steel plate 4 on both sides. Then, the wall sealing film 1 is adhered to the surface of the first steel plate 2 using hot air welding technology. When parallel splicing wall components, firstly, expanding foam is applied to the surface of the second steel plate 2 of one wall component and adhered to the wall. After adhesion, holes are drilled at the four drilling points 5. After drilling, expansion bolts are used to completely fix the wall component to the wall. Then, the second wall component is installed, expanding foam is applied in the same way, and the pins 32 are inserted into the grooves 31 of the first wall component and fixed with expansion bolts. Finally, the wall sealing film 1 of the second wall component extends beyond the coverage area of ​​the first steel plate, covering the drilling points 5, and is adhered together using hot air welding technology. This achieves a high degree of airtightness between the sealing boards.
