Description

Technical Field

[0001] This utility model relates to the field of civil defense door technology, and in particular to a deformation-resistant lightweight civil defense door. Background Technology

[0002] Civil defense, also known as civil air defense, refers to the government's mobilization and organization of the masses to take measures for air raid prevention, disaster relief, and rescue operations, and to prevent and mitigate the harm of disasters. Civil defense doors are a type of civil defense protective equipment. They are the doors at the entrances and exits of civil defense projects, possessing functions such as waterproofing, explosion-proofing, and resistance to air pollution, playing a crucial role, especially in dangerous situations. Civil defense doors are protective equipment, typically available in concrete and steel types, with dimensions varying according to specific needs.

[0003] Civil defense projects have the function of disaster prevention. In the event of an earthquake or explosion, the walls of civil defense projects may deform. At this time, the civil defense doors installed inside the walls may get stuck in the door frame and cannot be opened or closed normally, thus preventing the civil defense project from achieving its expected effect and potentially causing certain losses to the people. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a deformation-resistant lightweight civil defense door.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A deformation-resistant lightweight air-raid shelter door includes: an air-raid shelter door body, which is installed on a load-bearing door frame structure via two sets of hinges; a force-shaping top structure is installed on the upper wall of the load-bearing door frame structure; and a set of anti-deformation structures are installed on each of the two side walls of the load-bearing door frame structure. The load-bearing door frame structure includes: hinge seats, two door frame uprights, a load-bearing top plate, a load-bearing bottom plate, and two load-bearing columns. The two door frame uprights are located on the two side walls of the air-raid shelter door body. The hinge seats are installed on the front of the door frame uprights and are connected to the air-raid shelter door body via two sets of hinges. The load-bearing top plate is installed on the upper wall of the two door frame uprights, and the load-bearing bottom plate is installed on the lower wall of the two door frame uprights. The two load-bearing columns are respectively installed between the load-bearing top plate and the load-bearing bottom plate.

[0007] The present invention is further configured such that the force-shaping top structure includes: a force-shaping frame and a plurality of auxiliary force-shaping plates; the force-shaping frame is installed on the upper wall of the load-bearing top plate, and the plurality of auxiliary force-shaping plates are installed inside the force-shaping frame.

[0008] The present invention is further configured such that the anti-deformation structure includes: an anti-deformation base plate and an anti-deformation support plate; the anti-deformation base plate is installed on the side wall of the load-bearing base plate, and the anti-deformation support plate is installed between the anti-deformation base plate and the load-bearing top plate.

[0009] The present invention is further configured such that the force-shaping frame is trapezoidal, and the base of the force-shaping frame is at a 60-degree angle.

[0010] The present invention is further configured such that two auxiliary uprights are installed on the outer side of the two door frame uprights.

[0011] The present invention is further configured such that there is a 70-degree angle between the anti-deformation support plate and the anti-deformation base plate.

[0012] The beneficial effects of this utility model are as follows: In the event of an earthquake or explosion, this utility model strengthens the air-raid shelter door, ensuring that even if the wall of the air-raid shelter project deforms to a certain extent, the door frame will not deform excessively, thus preventing the main body of the air-raid shelter door from getting stuck in the door frame and being unable to open, thereby ensuring the disaster prevention and relief purpose of the air-raid shelter project.

[0021] Reference Figure 1-3 A deformation-resistant lightweight air-raid shelter door includes: an air-raid shelter door body 1, which is installed on a load-bearing door frame structure via two sets of hinges. A force-shaping top structure is installed on the upper wall of the load-bearing door frame structure, and a set of anti-deformation structures is installed on each of the two side walls of the load-bearing door frame structure. The load-bearing door frame structure includes: hinge seats 2, two door frame uprights 3, a load-bearing top plate 4, a load-bearing bottom plate 5, and two load-bearing columns 6. The two door frame uprights 3 are located on the two side walls of the air-raid shelter door body 1. The hinge seats 2 are installed on the front of the door frame uprights 3 and are connected to the air-raid shelter door body 1 via two sets of hinges. The load-bearing top plate 4 is installed on the upper wall of the two door frame uprights 3, the load-bearing bottom plate 5 is installed on the lower wall of the two door frame uprights 3, and the two load-bearing columns 6 are installed between the load-bearing top plate 4 and the load-bearing bottom plate 5, respectively. Two auxiliary uprights 11 are installed on the outer side of the two door frame uprights 3.

[0022] Specifically, the load-bearing structure includes a load-bearing frame 7 and several auxiliary load-bearing plates 8. The load-bearing frame 7 is installed on the upper wall of the load-bearing top plate 4, and several auxiliary load-bearing plates 8 are installed inside the load-bearing frame 7. The load-bearing frame 7 is trapezoidal, and the bottom of the load-bearing frame 7 is at a 60-degree angle.

[0023] Specifically, the anti-deformation structure includes: an anti-deformation base plate 9 and an anti-deformation support plate 10; the anti-deformation base plate 9 is installed on the side wall of the load-bearing base plate 5, and the anti-deformation support plate 10 is installed between the anti-deformation base plate 9 and the load-bearing top plate 4, with a 70-degree angle between the anti-deformation support plate 10 and the anti-deformation base plate 9.

[0024] Working principle: First, the utility model is installed. The operator first uses tools to level and fix the load-bearing base plate 5. The hinge seat 2, two door frame uprights 3, load-bearing top plate 4, and two load-bearing columns 6 are all pre-installed with the load-bearing base plate 5 in the factory and are integrated. At this time, the main body has completed the leveling and fixing work. Next, the operator directly welds the force distribution frame 7 and several auxiliary force distribution plates 8 onto the upper wall of the load-bearing top plate 4. The two sets of anti-deformation base plates 9 and anti-deformation support plates 10 are respectively installed on the two sides of the load-bearing top plate 4 and the load-bearing base plate 5. Finally, the wall is poured with concrete. The hinge seat 2, two door frame uprights 3, load-bearing top plate 4, and load-bearing base plate 5 are exposed, while the rest are poured inside the wall. Finally, the air-raid shelter door body 1 and the hinge seat 2 are connected by hinges.

[0025] When vibrations occur due to earthquakes, explosions, or other events, causing wall deformation, the wall is flattened and the deformation is divided into horizontal and vertical forces. To prevent vertical deformation, the trapezoidal force-shaping frame 7 transmits the pressure generated by the deformation to both ends of the load-bearing top plate 4, allowing the load-bearing column 6 to bear this pressure. The auxiliary force-shaping plate 8 prevents the force-shaping frame 7 from collapsing and prevents horizontal deformation. The two anti-deformation support plates 10 work simultaneously, one bearing tensile force and the other bearing compressive force, thus ensuring that the relative positions of the load-bearing top plate 4 and the load-bearing bottom plate 5 do not change. This ensures that the air-raid shelter door 1 can still be opened normally even after the wall has undergone a certain degree of deformation, both horizontally and vertically.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
