Description

Technical Field

[0001] The utility model belongs to the technical field of civil air defense doors, and particularly relates to a high-strength anti-deformation civil air defense door. Background Art

[0002] Civil air defense doors, whose full name is the protective doors at the entrances and exits of civil air defense projects, are specially installed at the entrances of various types of civil air defense projects (referred to as civil air defense projects). They are key facilities used to provide safe protection for the entry and exit of personnel and materials in emergency situations such as wars and natural disasters, as well as to resist corresponding shock waves, toxic agents, radioactive dust and other external threats. Civil air defense doors are usually made of concrete and steel materials, and have protective and sealing functions. According to different levels of design standards, they can withstand different impact loads and can prevent the penetration of toxic and harmful substances for a certain period of time.

[0003] Some existing designs of civil air defense doors may lack an effective impact-resistant structure. Especially when subjected to severe external impacts such as explosions, the door body is prone to deformation due to the lack of sufficient support or buffering design. This will not only affect the protective performance of the door body itself, but may also cause the door body to fail and be unable to open or close normally, thereby affecting the safe evacuation of personnel and the protection efficiency. Therefore, we hope to design a welding equipment with a new structure to solve this problem. Utility Model Content

[0006] A sealing plate is welded to the edge of the front surface of the high-strength steel plate, a deformation column is welded to the middle of the front surface of the high-strength steel plate, and a high-strength concrete layer is poured on the front side of the high-strength steel plate;

[0007] An elastic sealing layer is fixed on the front side of the sealing plate, and a high-strength steel plate 2 is movably mounted on the front side of the high-strength steel plate 1 through a plurality of evenly distributed deformation columns.

[0008] As a preferred embodiment, a flame retardant rubber plate 1 is fixed to the rear side of the high-strength steel plate 1, and a flame retardant rubber plate 2 is fixed to the front side of the high-strength steel plate 2. The arrangement of the flame retardant rubber plate 1 and the flame retardant rubber plate 2 can produce a buffer when the front or rear side of the civil defense door body is hit, thereby preventing foreign objects from directly contacting the high-strength steel plate 1 and the high-strength steel plate 2 on the civil defense door body.

[0010] As a preferred embodiment, the elastic sealing layer is made of flame-retardant rubber, and the front side of the elastic sealing layer abuts against two rear edges of the high-strength steel plate.

[0011] As a preferred embodiment, the deformation column includes a steel column, a steel cylinder and a buffer spring. The outer end of the steel column is welded to the two inner surfaces of the high-strength steel plate, and the inner end of the steel column is movably inserted into the outer end of the steel cylinder.

[0013] The length of the steel cylinder is greater than the thickness of the high-strength concrete. The setting of the deformation column ensures that the front side of the civil air defense door has a certain buffering capacity when it is subjected to a strong explosion impact, thereby greatly improving the use strength of the civil air defense door.

[0014] As a preferred embodiment, a pore 1 is opened outward in the middle of the inner end of the steel column, and the pore 1 does not penetrate the steel column. A pore 2 is opened downward on the outer side of the upper surface of the steel column, and the lower end of the pore 2 is connected to the outer end of the pore 1.

[0015] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: by installing the flame-retardant rubber plate 1 and the flame-retardant rubber plate 2 on the front and rear sides of the civil air defense door body, it is prevented that foreign objects directly come into hard contact with the high-strength steel plate 1 and the high-strength steel plate 2 on the civil air defense door body. When the civil air defense door body is hit, the flame-retardant rubber plate 1 and the flame-retardant rubber plate 2 undergo a certain deformation to form a buffer, which can effectively prevent the high-strength steel plate 1 and the high-strength steel plate 2 from deforming, thereby improving the service life of the civil air defense door body.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 4 The utility model provides a technical solution: a high-strength anti-deformation civil air defense door, comprising: a door frame 100 and a civil air defense door body 200, the door frame 100 is hingedly connected to the rear side of the civil air defense door body 200, and the civil air defense door body 200 comprises a high-strength steel plate 1 250, a high-strength steel plate 2 240, an elastic sealing layer 230 and a deformation column 280;

[0026] A sealing plate 220 is welded to the edge of the front surface of the high-strength steel plate 250, a deformation column 280 is welded in the middle of the front surface of the high-strength steel plate 250, and a high-strength concrete layer 270 is poured on the front side of the high-strength steel plate 250;

[0027] An elastic sealing layer 230 is fixed on the front side of the sealing plate 220 , and a high-strength steel plate 2 240 is movably mounted on the front side of the high-strength steel plate 1 250 via a plurality of uniformly distributed deformation columns 280 .

[0028] See also Figure 1 to Figure 2 A flame retardant rubber plate 210 is fixed on the rear side of the high-strength steel plate 250, and a flame retardant rubber plate 260 is fixed on the front side of the high-strength steel plate 240. The arrangement of the flame retardant rubber plate 210 and the flame retardant rubber plate 260 can produce a buffer when the front or rear side of the civil defense door body 200 is hit, thereby preventing foreign objects from directly contacting the high-strength steel plate 250 and the high-strength steel plate 240 on the civil defense door body 200.

[0029] The structure and size of the flame retardant rubber plate 210 are the same as those of the flame retardant rubber plate 260. A plurality of evenly distributed embedded springs 211 are embedded in the flame retardant rubber plate 210, and a plurality of evenly distributed bolts 212 are installed on the outer side of the flame retardant rubber plate 210. The inner end of each bolt 212 on the flame retardant rubber plate 210 is threadedly connected to the outer side of the high-strength steel plate 250.

[0030] As the first embodiment of the utility model, in actual use, if the front or rear side of the civil air defense door body 200 is hit, the foreign object directly contacts the flame retardant rubber plate 1 210 and the flame retardant rubber plate 2 260 at the corresponding position, avoiding direct hard contact between the foreign object and the high-strength steel plate 1 250 and the high-strength steel plate 2 240 on the civil air defense door body 200. When the civil air defense door body 200 is hit, the flame retardant rubber plate 1 210 and the flame retardant rubber plate 2 260 are deformed to form a buffer, which can effectively prevent the high-strength steel plate 250 from being hit. 0 and the high-strength steel plate 240 are deformed, thereby increasing the service life of the civil air defense door body 200. At the same time, when the flame retardant rubber plate 1 210 and the flame retardant rubber plate 260 are damaged, it is only necessary to remove the bolts 212 at the corresponding positions to replace the flame retardant rubber plate 1 210 and the flame retardant rubber plate 2 260. The use is convenient and the replacement is simple (the above-mentioned flame retardant rubber plate 1 210 and the flame retardant rubber plate 2 260 can be made of a whole flame retardant plate, or can be formed by splicing multiple small flame retardant plates, which can be selected according to actual use requirements).

[0031] See also Figures 1 to 4 The elastic sealing layer 230 is made of flame-retardant rubber, and the front side of the elastic sealing layer 230 abuts against the rear edge of the high-strength steel plate 240 .

[0032] The deformation column 280 includes a steel column 282 , a steel cylinder 281 and a buffer spring 285 . The outer end of the steel column 282 is welded to the inner surface of the high-strength steel plate 240 , and the inner end of the steel column 282 is movably inserted into the outer end of the steel cylinder 281 .

[0033] A buffer spring 285 is installed inside the inner end of the steel cylinder 281, and the outer end of the buffer spring 285 abuts against the inner end of the steel column 282. The diameter of the inner end of the steel column 282 is greater than the diameter of the outer end.

[0034] The length of the steel cylinder 281 is greater than the thickness of the high-strength concrete. The setting of the deformation column 280 enables the front side of the civil air defense door to have a certain buffering capacity when it is subjected to a strong explosion impact, thereby greatly improving the service strength of the civil air defense door.

[0035] An air hole 283 is opened outward in the middle of the inner end of the steel column 282, and the air hole 283 does not penetrate the steel column 282. An air hole 284 is opened downward on the outer side of the upper surface of the steel column 282, and the lower end of the air hole 284 is connected to the outer end of the air hole 283.

[0036] As the second embodiment of the utility model, based on the above-mentioned first embodiment, in actual use, when a violent explosion occurs on the front side of the civil defense door body 200, the shock wave will generate an impact force on the flame retardant rubber plate 260. When the impact force hits the flame retardant rubber plate 260, it will push the high-strength steel plate 240 to move backward. When the high-strength steel plate 240 is subjected to the thrust, it will synchronously squeeze the elastic sealing layer 230 and the deformation column 280. Multiple deformation columns 280 cooperate with the elastic sealing layer 230 to synchronously deform and generate uniform elastic potential energy to buffer the thrust received by the high-strength steel plate 240, thereby greatly reducing the impact hazard caused by the impact force to the civil defense door body 200, avoiding deformation caused by the civil defense door body 200 being unable to release the force due to a large impact force, and improving the service life of the civil defense door body 200.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
