Description

Technical Field

[0001] This utility model relates to the field of roof structure for civil defense projects, and more specifically, to a roof structure for civil defense projects with a buffer layer. Background Technology

[0002] The roof slab of a civil defense project is a key load-bearing and protective component in the structural system of the protective structure. It primarily bears multiple burdens, including the impact of nuclear blast shockwaves during wartime, direct hits from conventional weapons, and the load of the superstructure during peacetime. Its design employs a high-strength reinforced concrete cast-in-place structure, with reinforcement enhancing its bending and shear resistance, and expansion joints addressing temperature stress issues. The roof slab must meet the resistance level requirements of the Civil Air Defense Engineering Design Code, and its layered protective structure (including a waterproof layer, a soil covering layer, and a camouflage layer) achieves concealment and buffering functions.

[0003] When the roof slab of a civil defense project suffers damage to a certain extent (such as exposed reinforcing bars or localized deformation), personnel inside often find it difficult to directly assess its remaining load-bearing capacity. This is primarily due to two reasons: first, hidden damage may be concealed by the surface structure; and second, there is a lack of professional testing tools to quantify the extent of damage in real time. This blind spot in assessment can lead to misjudgments of the actual safety margin of the roof slab, potentially causing collapse risks during aftershocks or secondary impacts, highlighting the limitations of wartime engineering monitoring methods.

[0004] How to design a roof structure with a buffer layer for civil defense projects to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a roof structure for civil defense projects with a buffer layer, aiming to improve the problems mentioned in the background.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a roof structure for a civil defense project with a buffer layer, including a base. A roof body and a base frame are fixedly connected to the side wall of the base. The roof body is a reinforced concrete structure. A buffer plate is provided below the roof body. A stabilizing plate is fixedly connected to the top of the base frame. A set of fixing seats is fixedly connected to the top of the stabilizing plate. The set of fixing seats is evenly arranged in a straight line in the width direction of the buffer plate. The fixing seats are located at the center position in the length direction of the buffer plate. A first buffer spring is fixedly connected to the top of the fixing seat. A fixing plate is fixedly connected to the top of the first buffer spring. A second buffer spring is fixedly connected to the top of the stabilizing plate. Multiple lamp covers are fixedly connected to the bottom of the base frame. An alarm component is provided on the top of each lamp cover.

[0008] Preferably, the buffer plate is made of alloy spring steel, and the buffer plate is continuously "S" shaped in both the length and width directions, with the bending radius in the length direction being greater than the bending radius in the width direction.

[0009] Preferably, the fixing plate is abutted against the top plate body, the second buffer spring is inclined, the top of the second buffer spring is fixedly connected to the buffer plate, and the base frame is welded from multiple crisscrossing steel frames.

[0010] Preferably, the alarm assembly includes a fixed frame fixedly connected to the bottom of the stabilizing plate, a light panel fixedly connected to the bottom of the fixed frame, a plurality of LEDs being provided on the light panel, the light panel being electrically connected to an external power supply, a housing fixedly connected to the stabilizing plate, the housing being tubular and penetrating the stabilizing plate, an alarm light fixedly connected to the bottom of the housing, the alarm light having two first contact points, and a sliding rod slidably provided on the inner side wall of the housing, the sliding rod being tightly fitted and connected to the housing.

[0013] Preferably, the two second contacts correspond to the positions of the two first contacts, and the two second contacts are electrically connected to the two poles of the external battery, respectively.

[0014] The beneficial effects of this utility model are as follows: By setting a continuous "S"-shaped buffer plate made of alloy spring steel, not only is the stability and impact resistance of the overall structure improved, but it can also effectively absorb and disperse the impact force from the outside, preventing the impacting object from penetrating the top plate; the buffer plate works in conjunction with the first and second buffer springs to provide continuous support and buffering when the top plate is damaged, delaying the time of structural failure and buying valuable time for personnel evacuation; at the same time, the alarm component set in the buffer structure can automatically trigger the alarm light when the top plate is severely deformed, promptly reminding the personnel inside to take emergency measures, and can still rely on the battery to provide temporary lighting after the external power is interrupted, improving safety and practicality.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0023] Example, refer to Figures 1-5A type of roof structure for civil defense engineering with a buffer layer includes a base 1. A roof body 2 and a base frame 5 are fixedly connected to the side walls of the base 1. The roof body 2 is a reinforced concrete structure. A buffer plate 3 is installed below the roof body 2. A stabilizing plate 4 is fixedly connected to the top of the base frame 5. A set of fixing seats 6 is fixedly connected to the top of the stabilizing plate 4. The fixing seats 6 are evenly arranged in a straight line along the width direction of the buffer plate 3. The fixing seats 6 are located at the center position along the length direction of the buffer plate 3. A first buffer spring 7 is fixedly connected to the top of the fixing seat 6. A first buffer spring 7 is fixedly connected to the top of the first buffer spring 7. The top of the fixed plate 9 and the stabilizing plate 4 are fixedly connected to the second buffer spring 8. The bottom of the base frame 5 is fixedly connected to multiple lamp covers 11. The top of the lamp covers 11 is equipped with an alarm component. The buffer plate 3 is made of alloy spring steel. The buffer plate 3 is set in a continuous "S" shape in both the length and width directions. The bending radius of the buffer plate 3 in the length direction is greater than the bending radius in the width direction. The fixed plate 9 is set against the top plate body 2. The second buffer spring 8 is set at an angle. The top of the second buffer spring 8 is fixedly connected to the buffer plate 3. The base frame 5 is welded together from multiple crisscrossing steel frames.

[0024] The alarm assembly includes a mounting bracket 12 fixedly connected to the bottom of a stabilizing plate 4. A light panel 13 is fixedly connected to the bottom of the mounting bracket 12. The light panel 13 is provided with multiple LED beads 14 and is electrically connected to an external power source. A housing 15 is fixedly connected to the stabilizing plate 4. The housing 15 is tubular and penetrates the stabilizing plate 4. An alarm light 16 is fixedly connected to the bottom of the housing 15. The alarm light 16 is provided with two first contacts 17. A slide rod 18 is slidably provided on the inner side wall of the housing 15 and is tightly connected to the housing 15. Two blind holes are opened on the slide rod 18. An auxiliary spring 19 is fixedly connected to the inner side wall of the bottom of the blind hole. A push rod 20 is fixedly connected to the bottom end of the auxiliary spring 19. A second contact 21 is fixedly connected to the bottom of the push rod 20. The two second contacts 21 correspond to the positions of the two first contacts 17 and are electrically connected to the two poles of an external battery, respectively.

[0025] It should be noted that: by using a buffer plate 3 made of alloy spring steel, and setting it in a continuous "S" shape in both its length and width directions, it is used to withstand the impact force from the top plate body 2. Compared with traditional spring buffers, it has higher stability. Since the buffer plate 3 is a continuous plate, it plays a protective role, intercepting the impacting object from continuing to impact and penetrate the entire top of the civil defense building. When the top plate body 2 applies pressure to the buffer plate 3, the buffer plate 3 extends to both sides from the fixed seat 6 to buffer the impact force from the top plate body 2. By setting an inclined second buffer spring 8, when the buffer plate 3 is compressed, the second buffer spring 8 is gradually compressed and gradually tilts to the vertical, improving the stability of the second buffer spring 8 and preventing the second buffer spring 8 from being over-inclined and compressed. By setting a sliding rod 18 to be tightly connected to the housing 15 and sliding relative to it, when the top plate is not subjected to a large external force, the sliding rod 18 and the housing 15 are fixed by friction, without the need for additional locking components, saving costs.

[0026] The working principle of the roof slab structure of the civil defense project with a buffer layer is as follows: If the roof slab structure is subjected to external impact, the roof slab body 2 resists the impact through its own reinforced concrete structure. The buffer plate 3 and the first buffer spring 7 below play a buffering role on the roof slab body 2. If the concrete structure of the roof slab body 2 is damaged, when the roof slab body 2 is impacted again, the steel structure inside the roof slab body 2 deforms and presses down, putting pressure on the buffer plate 3, the first buffer spring 7 and the second buffer spring 8. The buffer plate 3, the first buffer spring 7 and the second buffer spring 8 play a buffering and supporting role on the roof slab body 2, preventing the roof slab body 2 from being excessively deformed. If the top plate body 2 is severely deformed, the buffer plate 3 tends to be flattened. The deformed buffer plate 3 presses against the lower slide bar 18, and the slide bar 18 moves downward. Through the auxiliary spring 19, it drives the push rod 20 to move downward, so that the first contact 17 and the second contact 21 make contact, connecting the alarm light 16 to the external battery circuit. The alarm light 16 lights up to remind the personnel inside the civil defense project that the top plate at this location has been severely damaged and that they need to evacuate in time. Even if the lamp bead 14 fails due to the interruption of external power, the alarm light 16 can still provide temporary lighting function under the power of the battery.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
