Description

Technical Field

[0001] This utility model relates to a steel plate protective wall, and more particularly to a high-temperature resistant heat-insulating protective wall module. Background Technology

[0002] In certain areas of a bank where the wall thickness or strength does not meet standards, steel plates should be used for protection. When using steel plates, a steel reinforcement mesh with a thickness of 4mm or greater should be added to the inner side of the wall. The steel plate thickness should be Q235 or higher. Reinforcing mesh should also be used, with a nominal diameter of 14mm or greater and a mesh spacing of 150mm x 150mm or less, and it should be reliably connected to the main building structure. Patents such as 202022160395.5 (titled "An Installation Structure for a Steel Plate Protective Wall") and 22221612963.3 (titled "A Steel Plate Protective Wall for Banks") are examples of steel plate protective walls used in banks.

[0003] However, in certain specific areas, such as cash storage areas, insurance material storage areas, and bank material storage areas, fire prevention requirements are relatively high. While steel plate protective walls provide security and protection against theft, their high thermal conductivity due to their metallic nature means that if a fire breaks out on the outside of the steel plate protective wall, the heat will be rapidly transferred to it, causing the areas in contact with the steel plate to ignite and destroy the stored items.

[0004] In the prior art, such as the applicant's earlier application, application number "202223122677.1", patent title "A Steel Plate Wall Module and Fireproof and Heat-Insulating Steel Plate Protective Wall", it is used to increase fire resistance. However, this structure has the following shortcomings:

[0005] 1. The fireproof and heat-insulating layer is set between two steel plates and next to the steel mesh. During the manufacturing process, especially when welding the steel plates and steel mesh, the ease of welding is affected, resulting in low production efficiency. In addition, the welding process may also damage some of the fireproof and heat-insulating layer material.

[0006] 2. Without a fireproof and heat-insulating layer, the high-temperature resistance, heat insulation, and fire resistance are poor. Summary of the Invention

[0007] The purpose of this invention is to provide a high-temperature resistant heat insulation protective wall module. By using this structure, high-temperature resistance can be effectively guaranteed, while reducing the difficulty of production and processing and improving production efficiency.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a high-temperature resistant heat insulation protective wall module, including a high-temperature resistant sealing ring and steel plates respectively disposed on both sides of the high-temperature resistant sealing ring, wherein the two steel plates and the interior of the high-temperature resistant sealing ring form a sealed chamber, and the interior of the sealed chamber is filled with inert gas.

[0009] In the above technical solution, the two sides of the high-temperature resistant sealing ring are respectively sealed and connected to the two sides of the steel plate.

[0010] In the above technical solution, the contact point between the steel plate and the high-temperature resistant sealing ring is sealed with sealant.

[0011] And / or, the sealant is a high-temperature resistant sealant.

[0012] In the above technical solution, each of the steel plates is also connected to a high-temperature resistant sealing ring by multiple screws;

[0013] One end of the screw is connected to the steel plate, and the other end of the screw is connected to the high-temperature resistant sealing ring;

[0014] And / or, the screws on the front steel plate are staggered with the screws on the rear steel plate.

[0015] In the above technical solution, the high-temperature resistant sealing ring is a double layer, and the two layers of the high-temperature resistant sealing ring are sealed and fitted together. The outer edge of the rear side wall of the first layer of the steel plate is sealed and fitted together with the front side of the front high-temperature resistant sealing ring, and the outer edge of the front side plate of the other layer of the steel plate is sealed and fitted together with the rear side of the rear high-temperature resistant sealing ring.

[0016] In the above technical solution, each of the steel plates is also connected to a high-temperature resistant sealing ring by multiple screws;

[0017] The end of the screw passes through the corresponding steel plate and the adjacent high-temperature resistant sealing ring and connects to another high-temperature resistant sealing ring.

[0018] And / or, the screws on the front steel plate are staggered with the screws on the rear steel plate.

[0019] In the above technical solution, the high-temperature resistant sealing ring is a polytetrafluoroethylene (PTFE) sealing ring.

[0020] In the above technical solution, at least one air hole is provided on the outer surface of the high-temperature resistant sealing ring, which communicates with the sealing chamber;

[0021] And / or, the pores are further filled with a high-temperature resistant sealant to seal the pores.

[0022] In the above technical solution, the high-temperature resistant sealing ring is further provided with at least one mounting hole, the two ends of the mounting hole are respectively connected to the front end face and the rear end face of the high-temperature resistant sealing ring, and each of the steel plates is provided with a through hole facing the mounting hole.

[0023] In the above technical solution, there is a gap between the mounting hole and the sealing chamber.

[0024] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0025] 1. In this utility model, a sealed chamber is set between two steel plates and filled with inert gas. By setting the inert gas, the heat insulation effect can be effectively increased.

[0026] 2. In this utility model, a high-temperature resistant sealing ring and a steel plate are used to form a sealed chamber, which makes production easier and more efficient.

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0034] Example 1: See Figure 1-4As shown, a high-temperature resistant heat insulation protective wall module includes a high-temperature resistant sealing ring 1 and steel plates 2 respectively disposed on both sides of the high-temperature resistant sealing ring 1. The two steel plates 2 and the interior of the high-temperature resistant sealing ring 1 form a sealed chamber 3, and the sealed chamber 3 is filled with inert gas.

[0035] In this embodiment, the steel plate thickness is 6mm. Of course, thicker or thinner steel plates can also be selected, depending on the actual situation. The high-temperature resistant heat-insulating protective wall module is directly installed on the outside or inside of the original protective wall. It adds a separate high-temperature resistant heat-insulating protective wall to the original protective wall (which can be a concrete wall, brick wall, or steel plate wall) to enhance the heat insulation and high-temperature resistance performance of the original protective wall. In this structure, the steel plate itself possesses strong high-temperature resistance. The arrangement of two layers of steel plates, which are not in direct contact and are not connected by metal heat transfer components, also enhances the heat insulation capacity. Furthermore, a high-temperature resistant sealing ring connects the two steel plates, and the sealed cavity formed by the sealing ring and the two steel plates is filled with inert gas, further improving the high-temperature resistance and heat insulation performance. This design is relatively inexpensive, simple to manufacture, and provides good protection (the steel plate has strong explosion-proof, anti-theft, and impact-resistant capabilities). Compared to directly using fireproof and heat-insulating materials, even when in direct contact with flames, the temperature will not exceed the steel plate's ignition point (which is far higher than that of heat-insulating and fireproof materials, such as fire-resistant cotton), thus effectively improving high-temperature resistance, heat insulation, and fireproofing.

[0036] The high-temperature resistant sealing ring 1 is sealed to the steel plates 2 on both sides. This sealing connection prevents the leakage of inert gas in the sealed cavity, ensuring a sealing effect and thus guaranteeing heat insulation and high-temperature resistance.

[0037] The contact area between the steel plate and the high-temperature resistant sealing ring is sealed with a high-temperature resistant sealant. This sealant further seals the contact area between the steel plate and the high-temperature resistant sealing ring, thereby improving the sealing effect of the sealed chamber and preventing leakage of internal inert gas. Simultaneously, the use of a high-temperature resistant sealant ensures that the protective wall module will not melt and cause leakage of the sealed chamber when exposed to temperatures not exceeding a certain limit, thus guaranteeing the sealing effect of the sealed chamber.

[0038] The high-temperature resistant sealing ring is a polytetrafluoroethylene (PTFE) sealing ring, made of PTFE. It can withstand high temperatures without melting, thus ensuring the sealing effect of the sealed chamber. Of course, the high-temperature resistant sealing ring can also be made of other materials, as long as the sealing effect and high-temperature resistance are guaranteed.

[0039] See Figure 3As shown, the outer surface of the high-temperature resistant sealing ring 1 is provided with at least one air hole 4 that communicates with the sealing chamber 3; the air hole 4 is also filled with high-temperature resistant sealant to seal the air hole 4.

[0040] In this embodiment, the high-temperature resistant sealing ring on the sealed chamber side is on the inner side, with vent holes. After the steel plate and the high-temperature resistant sealing ring are connected, the sealed chamber is evacuated through the vent holes. After evacuation, inert gas is filled into the sealed chamber. After the inert gas filling is completed, high-temperature resistant sealant is filled into the vent holes to block them and prevent inert gas from leaking out, thus ensuring a sealing effect (or, without evacuation, at least two vent holes are provided, one of which is used for filling inert gas. During the inert gas filling process, the air in the sealed chamber will be squeezed out through the other vent hole, and then the vent hole can be blocked with high-temperature resistant sealant. As long as the inert gas can be filled into the sealed chamber, it is acceptable).

[0041] See Figure 2 , 3 As shown, the high-temperature resistant sealing ring 1 is also provided with at least one mounting hole 5. The two ends of the mounting hole 5 are respectively connected to the front end face and the rear end face of the high-temperature resistant sealing ring 1. Each of the steel plates 2 is provided with a through hole 6 facing the mounting hole 5. There is a gap between the mounting hole and the sealing chamber.

[0042] In this embodiment, two steel plates are respectively positioned on the front and rear sides of the high-temperature resistant sealing ring, with the outer edge of the high-temperature resistant sealing ring flush with the outer edge of the steel plates. Multiple mounting holes can be provided, arranged around the high-temperature resistant sealing ring. The number and position of the mounting holes are selected or adjusted according to the actual installation location. There is a gap between the mounting holes and the inner surface of the high-temperature resistant sealing ring, ensuring the sealing effect of the sealing chamber and preventing inert gas leakage from the mounting holes. The presence of mounting holes and through holes facilitates the insertion of bolts or other mounting parts for fixing the high-temperature resistant heat insulation protective wall module to the required location (e.g., a wall or steel plate wall).

[0043] In another embodiment, in addition to the sealant connecting the steel plates, to further improve the connection strength between the steel plates and the high-temperature sealing ring, each steel plate 2 is further connected to the high-temperature sealing ring 1 by multiple screws 7; one end of each screw 7 is connected to the steel plate 2, and the other end is connected to the high-temperature sealing ring 1. In this method, after the sealant connects the steel plates and the high-temperature sealing ring, screws are used to connect them, increasing the strength. Preferably, the holes for the screws on the steel plates are countersunk holes, so the screw head will enter the countersunk hole and will not protrude outwards. Of course, it can also be a non-countersunk hole, where the screw head can protrude outwards from the outside of the steel plate. This is not very aesthetically pleasing, but it does not affect the connection strength. Of course, there is another connection method: using a bolt and nut structure. One end of the bolt passes through the steel plate, the high-temperature resistant sealing ring, and another steel plate, with the bolt head resting against the outside of one of the steel plates. The other side is connected by a nut and bolt, using the bolt and nut to clamp and limit the two steel plates and the high-temperature resistant sealing ring. This method is less aesthetically pleasing and less efficient in installation, but it provides better stability.

[0044] See Figure 1 , 3 As shown, the screws 7 on the front steel plate 2 and the screws 7 on the rear steel plate 2 are staggered. This staggered arrangement allows for the placement of more screws, thereby ensuring the connection strength between the high-temperature sealing ring and the corresponding steel plate, and preventing interference between the front and rear screws when connecting to the high-temperature sealing ring.

[0045] In this invention, the high-temperature resistant sealing ring can take several forms. The first type is a single-layer structure. The second type consists of two layers, sealed together. The outer edge of the rear sidewall of the first layer of steel plate is sealed to the front side of the front high-temperature resistant sealing ring, and the outer edge of the front sidewall of the second layer of steel plate is sealed to the rear side of the rear high-temperature resistant sealing ring. Alternatively, it can be a three-, four-, or more-layer structure (multi-layer high-temperature resistant sealing rings bonded together from front to back using high-temperature resistant sealant). In this structure, with double or more layers of high-temperature resistant sealing rings, the thickness of each single-layer sealing ring can be thinner. Different numbers of high-temperature resistant sealing rings can be selected based on required insulation or thickness. This method not only allows adjustment of the thickness of the protective wall module but also the volume of the sealing chamber, the amount of inert gas that can be filled, and its insulation performance. In this embodiment, two layers of mutually bonded high-temperature resistant sealing rings are selected.

[0046] The structure adopts a double-layer high-temperature resistant sealing ring, and each of the steel plates 2 is also connected to the high-temperature resistant sealing ring 1 by multiple screws 7;

[0047] The end of the screw passes through the corresponding steel plate and the adjacent high-temperature resistant sealing ring and connects to another high-temperature resistant sealing ring.

[0048] The screws on the front steel plate are staggered with the screws on the rear steel plate.

[0049] In this structure, the front steel plate and the front high-temperature resistant sealing ring are sealed together with high-temperature resistant sealant, and the rear steel plate and the rear high-temperature resistant sealing ring are also sealed together with high-temperature resistant sealant to ensure a good seal. Screws connect the two layers of high-temperature resistant sealing rings and the layer of steel plate to prevent the adhesive between the two layers of high-temperature resistant sealing rings from coming off and to ensure the connection strength.

[0050] The high-temperature resistant sealant consists of three layers: one layer between the two high-temperature resistant sealing rings, and another layer between the high-temperature resistant sealing ring and the steel plate. The presence of these three layers of high-temperature resistant sealant ensures a good sealing effect.

[0051] In this invention, the high-temperature resistant sealing ring can also have two structures: the first is a sealed frame or ring structure (in this invention, it is a frame structure). In this way, the manufacturing cost will be higher, but the sealing effect can be guaranteed.

[0052] The second method involves using multiple sealing strips to form a frame or ring structure, with the joints bonded together using high-temperature resistant sealant (in this invention, a frame structure is formed). In this method, the steel plate has a square structure, and four sealing strips (top, bottom, left, and right) form a high-temperature resistant sealing ring. This structure uses high-temperature resistant sealant to seal adjacent sealing strips, effectively ensuring a tight seal. This embodiment uses the second method, which maximizes the use of the sealing strip material (polytetrafluoroethylene). Sealing strips of appropriate width and length are cut and bonded using high-temperature resistant sealant, reducing material waste (the first method may result in some material waste).

[0053] More preferably, the sealing strips in the front and rear high-temperature resistant sealing rings are arranged in a staggered manner. For example, the connection between two adjacent sealing strips of the front high-temperature resistant sealing ring is located in front of one of the sealing strips of the rear high-temperature resistant sealing ring, and the connection between two adjacent sealing strips of the rear ring is located behind one of the sealing strips of the front ring. This ensures that the sealant between adjacent sealing strips has a steel plate and a sealing strip on both sides, guaranteeing the strength of the high-temperature resistant sealing rings on both sides, as shown in Figure 4.
