[0002] Explosion-proof wall, also known as explosion-resistant wall, has the ability to resist explosion shock waves and can limit the destructive effects of explosion to a certain range of wall structure. It is used for peripheral security and defense walls, equipment revetments, and equipment in search areas for explosives and contraband. Compared with reinforced concrete explosion-proof wall, it has the advantages of light weight, easy installation and unloading, and recyclable reuse.

[0003] In the production process of fireworks, safe houses or explosion-proof houses are often used to test and store flammable and explosive items such as fireworks. Most of their wall structures are required to have certain explosion-proof and impact-resistant properties to meet the testing and storage needs of most fireworks. At present, most explosion-proof wall structures are mostly made of steel frames or concrete. Although they can meet basic explosion-proof requirements, they are difficult to use in the fireworks testing process because there are many types of fireworks and they have certain impact force and explosion radius. At the same time, due to the characteristics of fireworks themselves, they have a certain continuity when they are ignited and are prone to repeated impacts on the wall within a certain range. Although the overall structure of the traditional explosion-proof wall has a certain explosion-proof performance, it often has certain deficiencies when subjected to continuous impacts within a local range under such circumstances. In addition, the wall surface is prone to potholes or even deformation, which affects the stability of the wall structure and increases the difficulty of maintenance. Utility Model Content

[0007] Furthermore: a matching steel plate mesh is installed between the explosion-proof surface layer of the wall structure and the steel frame.

[0008] Further: the explosion-facing surface layer includes a plurality of explosion-proof protective plates of the size of a square frame of an adapter cover, and the explosion-proof protective plates are installed on the steel frame at the corresponding square frame position through a detachable structure.

[0009] Furthermore: the steel keel adopts any structure of I-beam or H-beam, and the corresponding outer edge of the steel keel in the square frame is clamped with the edge of the steel plate.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0022] See also Figure 1-3 The present embodiment relates to an impact-resistant fireworks explosion-proof wall, including a wall structure composed of a steel frame and a plurality of steel plates 1, wherein the steel frame includes a steel keel 101 that is staggered in a horizontal and vertical direction, and the plurality of steel plates 1 are installed in a plurality of square frames 102 formed by the steel keels 101 that are staggered in a horizontal and vertical direction, and the wall structure is also provided with an adaptive explosion-proof surface layer 110, and the explosion-proof surface layer 110 is installed on the steel frame formed by the steel keels 101 that are staggered in a horizontal and vertical direction, and an arched plate 2 of an adaptive size is also provided above the steel plate 1 in the square frame 102, and the arched plate 2 is placed in a square groove 1021 between the explosion-proof surface layer 110 and the square frame 102 of the steel keel 101 to fix it.

[0023] Specifically in this embodiment, when the wall structure of this explosion-proof wall is installed, the explosion-facing surface layer 110 installed on the steel frame can press the arched plate 2 in the square groove 1021 formed by the steel keels 101 that are staggered horizontally and vertically, such as Figure 3As shown, the arched plate 2 between the steel plate 1 in the square frame 102 and the explosion-facing surface layer 110 can be deformed appropriately and fully contact the surfaces of the steel plate 1 and the explosion-facing surface layer 110 respectively. The safe house or explosion-proof house structure formed by the wall structure of this explosion-proof wall can further improve the explosion-proof performance of the overall structure of the explosion-proof wall through local adjustment of the square frame 102 and several steel plates 1 in the square frame 102. At the same time, the arrangement of the arched plate 2 on the square groove 1021 can further improve the impact resistance of the explosion-facing surface layer 110, and under the elastic action of the arched plate 2, reduce the degree of damage to the steel plate 1 in the square groove 1021 and the number of potholes and even the degree of deformation caused to the explosion-facing surface layer 110 during the fireworks firing process, thereby reducing the degree of deformation on the wall surface and further improving the stability and explosion resistance of the wall structure.

[0024] See also Figure 4 A matching steel plate mesh 120 is also installed between the explosion-proof surface layer 110 and the steel frame of the wall structure. The steel plate mesh 120 can further enhance the strength of the overall structure of the explosion-proof wall. At the same time, it improves the impact resistance of the explosion-proof surface layer 110 and disperses a certain impact force, plays a certain protective and buffering role for the explosion-proof surface layer 110, reduces the degree of damage to the explosion-proof surface layer 110 and the steel frame, ensures the stability of use and prolongs the service life.

[0025] The explosion-facing surface layer 110 includes a plurality of explosion-proof shields of the same size as the square frame 102, and the explosion-proof shields are all installed on the steel frame at the position corresponding to the square frame 102 through a detachable structure, such as Figure 1 or Figure 2 As shown in the figure, the explosion-facing surface layer 110 structure composed of multiple detachable explosion-proof protective plates can facilitate the installation, removal and replacement of the explosion-proof protective plates at the corresponding positions of the steel frame 100, facilitate daily inspection and later maintenance, and improve flexibility and convenience during use.

[0026] See also Figure 5 The steel keel 101 adopts any structure of I-beam or H-beam, and the corresponding outer edge of the steel keel 101 in the square frame 102 is clamped with the edge of the steel plate 1. The steel keel 101 can adopt any structure of I-beam or H-beam to form a steel frame according to the use requirements. At the same time, during the installation process, the corresponding outer edge of the steel keel 101 can be clamped with the edge of the steel plate 1, so that the steel plate 1 can be more stably fixed in the square frame 102, further improving the overall stability and impact resistance of the steel frame, and reducing the probability of the steel plate 1 being displaced or even falling off during use.

[0027] The steel structure further comprises a plurality of steel bars 103, wherein the plurality of steel bars 103 are passed through the steel keels 101 which are staggered in a horizontal and vertical manner to form a square frame 102 and the steel plates 1 in the square frame 102 are arranged and evenly distributed on the steel structure. Figure 5 As shown, the provision of the plurality of steel bars 103 can further improve the connection stability between the steel keel 101 and the steel plate 1, further enhance the overall strength of the steel frame 100 and its load uniformity, reduce the degree of local deformation, and improve stability during use.

[0028] See also Figure 6 , the steel plate 1 is also provided with a protection component 3, the protection component 3 includes a protection plate 31, a plurality of groups of protection contacts 311 are evenly distributed on the protection plate 31 and contact the bow plate 2 in the square groove 1021, the protection plate 31 is slidably arranged inside the steel plate 1 and connected with a plurality of groups of compression springs 32 arranged inside the steel plate 1, so that the plurality of groups of protection contacts 311 distributed thereon slide through a plurality of groups of matching slide grooves 11 arranged on the surface of the steel plate 1. When the wall structure of this explosion-proof wall is installed, the bow plate 2 is appropriately deformed in the square groove 1021 through the installation of the explosion-proof surface layer 110 and the pressure thereof, and contacts the plurality of groups of protection contacts 311 distributed on the anti-slide plate on the surface of the steel plate 1 in the square groove 1021. The plate 31 and the protective contact 311 at its corresponding position slide along the slide groove 11 under a certain pressure until the bow plate 2 is completely in contact with the surface of the steel plate 1. At the same time, the protective plate 31 is provided with a plurality of groups of compression springs 32 inside the steel plate 1. During use, the protective plate 31 can drive the protective contact 311 to slide out to an appropriate distance along the slide groove 11 on the surface of the steel plate 1 according to the degree of deformation of the bow plate 2. The setting of the protective component 3 on the steel plate 1 can play a certain protective role on the surface of the steel plate 1, and can also play a certain buffering and shock-absorbing effect on the bow plate 2, thereby indirectly improving the impact resistance of the explosion-proof surface layer 110, and reducing the degree of damage caused to the explosion-proof surface layer 110 and its internal bow plate 2 and steel plate 1 by the explosion-proof wall structure during the explosion-proof process.

[0029] An annular groove 12 is also provided on the outer edge of the steel plate 1 at the installation position of the protective component 3 on the steel plate 1, and a matching second steel plate mesh 4 is installed on the annular groove 12.
