Description

Technical Field

[0001] This utility model belongs to the field of civil defense door technology, and in particular relates to a civil defense door leaf with a composite dense rib structure. Background Technology

[0002] Civil defense, also known as civil protection, refers to the doors at the entrances and exits of civil defense projects. These doors are part of civil defense protective equipment and are used by the government to mobilize and organize the masses to take measures against air raids, disaster relief, and rescue operations to prevent and mitigate the harm of disasters. Examples include the very heavy, cement-filled doors in underground parking garages of residential areas and the doors of emergency shelters; these are civil defense doors used to protect refugees and prevent injury from explosives. As a crucial component of civil defense equipment, civil defense doors are protective devices installed to ensure the safety of personnel and supplies in response to potential wars or emergencies. With technological advancements, civil defense equipment is constantly improving, with new technologies and materials being applied to its development to enhance protective effectiveness, extend service life, and reduce maintenance costs.

[0003] Existing air-raid shelter doors are mainly classified into two types based on their materials: steel structure air-raid shelter doors and reinforced concrete air-raid shelter doors. Steel structure air-raid shelter doors are made using standard steel profiles and plates, through cutting, welding, and other processing techniques. Reinforced concrete air-raid shelter doors are mostly made of a single material, and existing traditional door panels suffer from problems such as heavy weight, complex processing, and difficult transportation. Furthermore, in extreme situations such as impacts or explosions, the protective performance of traditional door panels may not meet requirements. Therefore, developing an air-raid shelter door with a lightweight structure, simple processing, and excellent protective performance is particularly important. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the present invention aims to provide a civil defense door leaf with a composite dense rib structure, which solves the problems of complex structure and heavy weight of existing traditional door leaves.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A civil defense door leaf with a composite ribbed structure is provided, comprising at least one panel, wherein multiple ribs are provided in a crisscross pattern on the back of the panel; a first reinforcing member is provided inside the panel, and a second reinforcing member is provided for each of the ribs.

[0007] This utility model discloses a civil defense door leaf with a composite dense rib structure. By setting multiple dense ribs on the panel, the design of the multiple dense rib structure allows the civil defense door leaf to maintain sufficient strength while greatly reducing its weight and the complexity of its structure. This achieves a lightweight design for the civil defense door leaf, facilitating processing and transportation. It solves the problems of complex structure and heavy weight of existing traditional door leaves, and meets the dual requirements of modern civil defense projects for high performance and lightweight design.

[0008] Furthermore, as a specific arrangement of a civil defense door leaf with a composite ribbed structure, the number of panels is two; the two panels are overlapped and spaced apart; multiple ribs are arranged crisscrossingly between the two panels; and a rib is sealed at the four edges of each of the two panels.

[0009] The above-mentioned design makes the air-raid shelter door a double-panel structure. At the same time, the dense ribs set around the edges of the two panels achieve a seal, preventing foreign objects, dust and water from entering the interior of the double-panel air-raid shelter door.

[0010] Furthermore, each of the multiple ribs is filled with a filler material. This filler material increases the connection strength between the ribs, thereby enhancing the overall structural strength of the fire door. Specifically, the filler material can be foamed concrete, polyurethane foam, or similar materials.

[0011] Furthermore, the multiple ribs mentioned are one or more of composite material ribs, steel-clad beam ribs, steel-clad beam ribs, and combined ribs.

[0012] Furthermore, the cross-section of the composite material dense rib is rectangular, I-shaped, or T-shaped; the interior of the composite material dense rib is provided with the second reinforcing member, and both the first and second reinforcing members are multiple steel bars.

[0013] Furthermore, the steel-clad beam ribs include a hollow steel-clad beam, the interior of which is provided with a composite material, and the interior of which is provided with a second reinforcing member, which consists of multiple steel bars; the cross-section of the steel-clad beam ribs is rectangular or trapezoidal; the first reinforcing member consists of multiple steel bars.

[0014] Furthermore, the steel beam ribbed structure includes a ribbed base, which has a rectangular or trapezoidal structure. A second reinforcing member, which is an I-beam or a rectangular steel beam, is disposed inside the ribbed base. The rectangular steel beam is filled with a filling material, which is the same as the material of the ribbed base.

[0015] Furthermore, the combined dense ribs include a connecting beam, and a second reinforcing member is provided below the connecting beam. The second reinforcing member is an I-shaped steel beam, an L-shaped steel beam, or a rectangular steel beam; the first reinforcing member is multiple steel bars.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model provides a civil defense door leaf with a composite dense rib structure. The dense rib structure design allows the door leaf to maintain sufficient strength while greatly reducing its weight, reducing the complexity of the civil defense door leaf structure, and facilitating processing and transportation.

[0018] 2. The present invention provides a civil defense door leaf with a composite ribbed structure. The casting body and the ribbed material are both composite materials. The composite material can be TGCC composite material, UHPC composite material or matrix composite material, which enhances the protective performance of the door leaf and can effectively resist external forces under extreme conditions such as impact or explosion, thus protecting the safety of the interior of the civil defense project.
