Description

Technical Field

[0001] The utility model relates to the field of building materials, in particular to an explosion-proof plate. Background Art

[0002] With the development of society, people's safety awareness has become stronger and stronger, and explosion-proof panels have gradually been recognized. They have now been widely used in inflammable and explosive dangerous places such as chemical warehouses, oil and gas pipelines, and substations to effectively block the impact of explosion shock waves on the surrounding environment and personnel. They are also used in important places such as central control rooms and data centers to protect the safety of personnel and property. Among the existing explosion-proof panels, there is a technical solution with a patent application number of 201720098853.2 disclosed in Chinese patent literature, entitled "A bulletproof and explosion-proof plate". The solution mainly includes two steel plates and a corrugated plate sandwiched between the two steel plates. When in use, the wavy structure of the corrugated plate can absorb more energy, making the plate have better bulletproof and explosion-proof performance. However, in actual application, it still has the following shortcomings:

[0003] Because the contact area between the corrugated sheet and the steel plate is small, it is difficult to securely connect the three-layer structure of the corrugated sheet and the two steel plates. Therefore, it is necessary to fill the gap between the corrugated sheet and the steel plate with an insulating material such as polyester resin to increase the contact area. The polyester resin and the steel plate are then connected using an adhesive to securely connect the three-layer structure. Furthermore, insulating materials such as polyester resin will crack and fragment after being subjected to the impact of an explosion, making it easy for the steel plate and the corrugated sheet layers to separate, thus preventing the formation of a monolithic explosion-proof structure and significantly reducing explosion-proof performance. Furthermore, the use of adhesives is not environmentally friendly, and their viscosity decreases over time, affecting the reliability of the connection.

[0004] Therefore, in view of the above-mentioned deficiencies of the above-mentioned explosion-proof panels, it is very necessary to redesign their structure in order to better meet people's application needs. Utility Model Content

[0005] The present utility model aims to address the aforementioned problems and deficiencies by providing an explosion-proof panel that, through a tightening fixing structure, maintains the two steel plates firmly clamped to the corrugated plate, preventing separation and thus maintaining a monolithic explosion-proof structure. Furthermore, when the corrugated plate is subjected to a clamping force, it generates a self-rebound force that pushes the two steel plates apart, thereby maintaining the locking member and the two hooking lugs in a locked state and preventing them from loosening, thereby further ensuring the reliability of the connection structure. Furthermore, the panel does not require adhesives for the fixed connection, making it more environmentally friendly.

[0006] The technical solution of the present utility model is achieved as follows: an explosion-proof plate includes two steel plates and a corrugated plate sandwiched between the two steel plates, and is characterized in that it also includes a tightening and fixing structure, the tightening and fixing structure includes two hooking lugs and a locking member with a tapered slot, the two hooking lugs are respectively arranged symmetrically on the two steel plates, and the locking member is clamped on the two hooking lugs through the tapered slot to always clamp the two steel plates on the corrugated plates.

[0007] Preferably, the two hooking lugs and the locking member are both arranged in the gap between the two steel plates.

[0008] Preferably, the hooking lug is composed of a vertical connecting portion with one end fixed on the steel plate, and a hooking portion provided at the other end of the vertical connecting portion, and the hooking portion is bent toward one end of the vertical connecting portion.

[0009] Preferably, the locking member includes two oblique pieces and a connecting portion connecting the two oblique pieces into one body, the conical slot is formed by the two oblique pieces and the connecting portion, and the oblique piece is clamped on the hook portion.

[0010] Preferably, the ends of the two oblique pieces away from the connecting portion are respectively provided with extension portions extending toward the steel plate and placed on top of the steel plate.

[0011] Preferably, the gap between the corrugated plate and the two steel plates is filled with silica aerogel.

[0012] Preferably, the number of the tightening and fixing structures is four, and the four tightening and fixing structures are arranged around the corrugated plate.

[0013] The beneficial effects of the present invention are as follows: By tightening and fixing the structure, the present invention ensures that the two steel plates are always clamped to the corrugated plate. Even when subjected to explosion impact, the corrugated plate and the steel plate are unlikely to separate, thereby maintaining the explosion-proof panel's integrated explosion-proof structure. Furthermore, when the corrugated plate is subjected to a clamping force, it will also generate a rebound force, pushing the two steel plates apart, thereby keeping the locking member and the two hooking lugs in a locked state and preventing them from loosening, thus further ensuring the reliability of the connection structure. Furthermore, the use of such a tightening and fixing structure eliminates the need for adhesives for the fixed connection, making the explosion-proof panel more environmentally friendly.

[0017] like Figure 1 and Figure 2 As shown, the explosion-proof plate of the utility model includes two steel plates 1 and a corrugated plate 2 sandwiched between the two steel plates 1. In order to achieve the purpose proposed by the utility model, Figure 3 As shown, the present invention also includes a tightening and fixing structure 3 comprising two hooking lugs 31 and a locking member 32 with a tapered groove 33. The two hooking lugs 31 are symmetrically arranged on the two steel plates 1. The locking member 32 is clamped onto the two hooking lugs 31 via the tapered groove 33, thereby maintaining the two steel plates 1 firmly clamped to the corrugated plate 2. The present invention utilizes the tightening and fixing structure 3 to ensure that the two steel plates 1 are firmly clamped to the corrugated plate 2, preventing them from peeling off, thereby maintaining the explosion-proof panel's integrated explosion-proof structure. Furthermore, when the corrugated plate 2 is subjected to a clamping force, it generates a rebound force that pushes the two steel plates 1 apart, thereby maintaining the locking member 32 and the two hooking lugs 31 in a tightly locked state and preventing them from coming loose. This further ensures the reliability of the connection structure. Furthermore, the connection is made more environmentally friendly by not using adhesives.

[0018] In order to hide the tightening and fixing structure 3, improve the simplicity of the entire explosion-proof panel, and shorten the gap between the multiple explosion-proof panels as much as possible when the multiple explosion-proof panels are spliced ​​together, such as Figure 2 As shown, the two hooking lugs 31 and the locking member 32 are both arranged in the gap between the two steel plates 1 .

[0019] In order to further improve the structure of the hooking lug 31, make it simple, scientific and reasonable, and easy to manufacture, as Figure 3 As shown, the hooking lug 31 comprises a vertical connecting portion 311 fixed to the steel plate 1 at one end, and a hooking portion 312 disposed at the other end of the vertical connecting portion 311. The hooking portion 312 is curved toward one end of the vertical connecting portion 311. The vertical connecting portion 311 facilitates the connection of the hooking lug 31 to the steel plate 1. The hooking portion 312 facilitates the engagement with the tapered retaining groove 33 of the locking member 32, preventing loosening and ensuring the stability and reliability of the connection structure.

[0020] In order to further improve the structure of the locking member 32, make it simple, scientific and reasonable, and easy to manufacture, as Figure 3As shown, the locking member 32 includes two oblique pieces 321 and a connecting portion 322 connecting the two oblique pieces 321 into one. The conical slot 33 is formed by the two oblique pieces 321 and the connecting portion 322. The oblique piece 321 is clamped on the hook portion 312.

[0021] In order to prevent the inclined piece portion 321 and the hook portion 312 from being loosened, Figure 3 As shown, the ends of the two inclined pieces 321 away from the connecting portion 322 are each provided with an extension portion 323 extending toward the steel plate 1 and resting on the steel plate 1. Due to the provision of the extension portion 323, when subjected to an explosion, the steel plate 1 and the hooking lug 31 will move, and the steel plate 1 will compress the extension portion 323 together, thereby driving the inclined pieces 321 to move together, thereby ensuring that the inclined pieces 321 are always fixed on the hooking portion 312 and will not come loose, thereby further improving the reliability of the connection structure and allowing the explosion-proof panel to always maintain an integrated explosion-proof structure.

[0022] In order to further improve the thermal insulation and explosion-proof performance of explosion-proof panels, such as Figure 2 As shown, the gap between the corrugated plate 2 and the two steel plates 1 is filled with silica aerogel 4. Filling the silica aerogel 4 has good thermal insulation effect, and is lightweight, high-strength, explosion-proof, and flame-retardant. Thus, the explosion-proof panel made with the silica aerogel has excellent thermal insulation, explosion-proof, and flame-retardant properties.

[0023] In order to prevent the corrugated plate 2 from falling out from the gap between the two steel plates 1, Figure 1 As shown, there are four tightening and fixing structures 3, which are arranged around the corrugated plate 2. This structural design can enclose the corrugated plate 2 and confine it between the four tightening and fixing structures 3, thereby preventing the corrugated plate 2 from falling out of the gap between the two steel plates 1, so that the explosion-proof plate can always maintain an integrated explosion-proof structure.

[0024] In the actual manufacturing process, the hooking lug 31 is fixed on the steel plate 1 by welding.
