Description

Technical Field

[0001] This invention relates to the field of airtight protective door technology, specifically to a polymer composite protective airtight door. Background Technology

[0002] Traditional airtight protective doors generally include heavy-duty and light-duty types. Heavy-duty doors typically employ steel structures with enhanced protective capabilities and are generally used in key civil defense projects. Light-duty doors, on the other hand, often utilize lightweight steel structures and are commonly used in underground shopping malls, underground parking garages, and subways. While the structural weight of light-duty doors is significantly reduced compared to heavy-duty doors, their steel structure still contributes to their considerable weight, making opening and closing more difficult. Furthermore, they suffer from the drawback of not being able to balance protection and portability, as well as the difficulty of construction. Therefore, a lightweight airtight protective door that can balance protection and portability is needed to address these shortcomings. Summary of the Invention

[0003] This invention provides a polymer composite protective airtight door. The door leaf is made of polymer composite material, which takes into account both protection and lightness, and effectively improves the convenience of installation.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: A polymer composite protective airtight door includes a wall, a door frame structure, and a door leaf structure. The door frame structure is disposed in the wall and located on the surface of the wall, and the door leaf structure is movably disposed on the door frame structure. The door structure includes a door leaf and hinges. The door leaf is connected to the door frame structure via hinges. The door leaf includes unit modules and end plates. The unit modules are arranged in rows to form a door leaf panel. The end plates are located at the top and bottom of the door leaf panel.

[0005] Furthermore, the unit module includes a side module and a middle module. The middle module is provided with a slot and a strip, which are respectively provided on the two sides of the middle module. The side module is provided with a slot or a strip, which is provided on the inner side of the side module. Adjacent unit modules are spliced ​​together by slots and strips.

[0006] Furthermore, the unit module is provided with cavities, which are arranged in rows within the unit module and vertically within the unit module.

[0007] Furthermore, the cavity is located in the middle of the unit module, and the thickness of the force-bearing surface of the unit module is 3mm, while the thickness of the non-force-bearing surface is 2mm.

[0008] Furthermore, both the card slot and the card strip are T-shaped.

[0009] Furthermore, a sealant is provided between the card slot and the card strip.

[0010] Furthermore, the unit module is provided with a sealing strip, which is disposed on the non-stress-bearing surface of the unit module.

[0011] Furthermore, the door frame structure includes a door frame and a connecting bolt assembly. The connecting bolt assembly includes a sleeve and a connecting bolt. The sleeve is pre-embedded in the wall, and the connecting bolt is disposed in the sleeve. The door frame is connected to the wall through the connecting bolt.

[0012] Furthermore, the door frame includes a door frame and a threshold, the door frame being attached to the wall and the threshold being attached to the ground.

[0013] Furthermore, the unit module is made of carbon fiber reinforced epoxy resin composite material or glass fiber reinforced unsaturated polyester resin composite material.

[0014] The beneficial effects of this invention are as follows: Using high-polymer composite materials as the door leaf material significantly reduces the structural weight while maintaining protective performance. Furthermore, the door leaf is equipped with a cavity, which further reduces the weight of the door leaf while ensuring that the protective performance meets the requirements, thereby improving the convenience of opening and closing the door leaf and its overall performance. The modular assembly structure simplifies the production process and effectively improves the ease of construction. Attached Figure Description

[0017] The technical solutions in 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.

[0018] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] like Figure 1 As shown, a polymer composite protective airtight door includes a wall 1, a door frame structure 2, and a door leaf structure. The door frame structure 2 is disposed in the wall 1 and located on the surface of the wall 1. The door leaf structure is movably disposed on the door frame structure 2. The door leaf structure includes a door leaf 3 and a hinge. The door leaf 3 is connected to the door frame structure 2 through the hinge.

[0020] This invention uses a polymer composite material as the door leaf material, which enables the door leaf to have sufficient protective performance while significantly reducing its weight, thus making the door leaf easier to assemble. Because the door leaf combines lightweight and high strength, it will not be damaged at the joints when subjected to impact, so a modular structure can be adopted, further improving the ease of assembly. At the same time, by setting a cavity in the door leaf 3, the door leaf can meet both size requirements and structural strength requirements.

[0021] like Figure 4 , 5 As shown in Figure 6, the door leaf 3 includes unit modules 31 and a sealing plate. The unit modules 31 are arranged in rows to form a door leaf panel. The width of the door leaf panel is 600-1000mm and is composed of multiple unit modules 31. The sides of adjacent unit modules 31 are attached and spliced ​​together. The unit module 31 includes a side module and a middle module. The middle module is provided with a slot and a strip. The slot and strip are respectively provided on the left and right sides of the middle module. The slot and strip are both vertically continuous on the unit module 31. The side modules are provided with slots or strips. One side module has a slot on its inner side, and the other side module has a strip on its inner side. Adjacent unit modules 31 are spliced ​​together by slots and strips.

[0022] like Figure 5, 6 As shown in Figure 7, both the slot and the strip are T-shaped, and a tenon and mortise connection is formed between them. The tenon and mortise connection is used to assemble the unit module 31 into a door panel, which greatly reduces the assembly difficulty. Furthermore, since the door panel 3 is made of high-molecular composite material, its own structural strength is sufficient. Therefore, when the tenon and mortise structure is used for connection, the structural strength of the connection can still meet the protection requirements, and the door panel will not break or break at the tenon and mortise connection, thus ensuring the overall protection of the door panel 3.

[0023] Furthermore, a sealant is provided between the card slot and the card strip. The sealant can increase the connection strength between adjacent unit modules 31, and can also seal the gap between the card slot and the card strip, thereby improving the sealing performance of the door leaf 3.

[0024] like Figure 5 , 6 As shown in Figures 7 and 8, the unit module 31 is further provided with cavities 311, the cavities 311 are arranged in a row in the unit module 31, and the cavities 311 are arranged vertically in the unit module 31.

[0025] Because door leaf 3 is made of high-polymer composite material, it possesses sufficient structural strength despite its relatively thin dimensions, meeting the protection requirements of a protective airtight door. To ensure both the thickness and structural strength of door leaf 3, a cavity 311 is incorporated within it, balancing door leaf size, protective properties, and structural strength. The cavity 311 ensures that door leaf 3 maintains sufficient structural strength while meeting dimensional requirements and guaranteeing protection, while also significantly reducing its weight, making assembly easier.

[0026] Furthermore, the sealing plate is set at the top and bottom of the door panel, with a thickness of 2mm, to seal the cavity 311 in the door panel 3, and at the same time to strengthen the connection strength between the unit modules 31, so that the door panel 3 formed by splicing the unit modules 31 has sufficient connection strength in the vertical direction.

[0027] like Figure 7 As shown, the cavity 311 is located in the middle of the unit module 31, and multiple rows of cavities 311 are arranged in a row along the left and right direction of the unit module 31. The front edge of the cavity 311 and the front surface of the unit module 31 serve as the non-stress surface of the unit module 31, and the rear edge of the cavity 311 and the rear surface of the unit module 31 serve as the non-stress surface of the unit module 31. The thickness of the stress surface of the unit module 31 is 3mm, which has stronger protective performance, and the thickness of the non-stress surface is 2mm.

[0028] Preferably, the cavity 311 is a vertically continuous circular through hole with a diameter of 50 mm, and a cavity 311 is provided at intervals of 20-30 mm.

[0029] Furthermore, the unit module 31 and the sealing plate are made of carbon fiber reinforced epoxy resin composite material or glass fiber reinforced unsaturated polyester resin composite material, which has the advantages of being lightweight, having high specific strength, high specific modulus, fatigue resistance, and strong designability. Using them as door leaf material can effectively improve structural strength and reduce structural weight.

[0030] Furthermore, a sealing strip is provided on the unit module 31, and the sealing strip is disposed on the non-load-bearing surface of the unit module 31. The sealing strip is used to seal the gap between the door leaf 3 and the door frame 21.

[0031] like Figure 2 , 3 As shown, the door frame structure 2 further includes a door frame 21 and a connecting bolt assembly 22. The connecting bolt assembly 22 includes a sleeve and a connecting bolt. The sleeve is pre-embedded in the wall 1, and the connecting bolt is disposed in the sleeve and passes through the wall 1 using a tie-down connection. The door frame 21 is connected to the wall 1 via the connecting bolt. The door frame 21 includes a door frame and a threshold. The door frame is attached to the wall 1 and fixed to the wall via the connecting bolt. The threshold is attached to the ground and fixed to the ground with bolts.

[0032] The specific construction method of this invention is as follows: S1, Wall construction: Install the steel reinforcement cage of wall 1, install the sleeve in the steel reinforcement cage, and then pour the concrete of the wall. S2, Door frame construction: Install the door frame 21 at the wall opening and use tie bolts to pass through the sleeve to fix the door frame 21 to the wall 1; S3, Door leaf assembly: The prefabricated unit modules 31 are assembled according to the size of the door leaf 3, sealant is injected to seal the joints, then the sealing plate is pasted on the top and bottom of the door leaf panel, and finally the sealing strip is installed on the non-load-bearing surface of the door leaf 3 to complete the assembly of the door leaf 3. S4, Door leaf installation: Install the assembled door leaf 3 onto the door frame 21 using hinges to complete the installation of door leaf 3.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
