Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of civil air defence door processing, in particular to a civil air defence door leaf processing fixture. BACKGROUND

[0002] Civil air defence door is an important component in civil air defence engineering, and its type, material and specification will be different according to different civil air defence engineering requirements, such as reinforced concrete civil air defence door, steel civil air defence door and aluminum civil air defence door, etc. Reinforced concrete civil air defence door is widely used in various civil air defence engineering due to its high protection performance and durability. Steel civil air defence door is applied in occasions with high safety performance requirements. Aluminum civil air defence door plays an important role in some specific or temporary civil air defence facilities.

[0003] In order to ensure the final sealing performance and functionality of the civil air defence door leaf, the manufacturing process requires high precision in size and shape. Therefore, during the pouring process of the reinforced concrete civil air defence door, effective support needs to be provided for the door leaf to prevent its deformation or collapse, ensuring the integrity and completeness of the door leaf. In addition, reasonable pouring and vibrating can ensure the full filling of the concrete, reduce the internal voids and honeycombs, improve the compactness and strength of the concrete, and thus ensure the manufacturing quality of the door leaf.

[0004] After searching, the Chinese utility model patent with publication number CN218365523U discloses a civil air defence door concrete pouring clamp table, which comprises a platform, a clamp mechanism and a stacking support mechanism. The clamp mechanism comprises a plurality of clamp assemblies distributed along the edge of the platform, which can be slidably arranged along the edge of the platform. The stacking support mechanism comprises a plurality of support assemblies distributed around the platform, each support assembly comprising a support plate extending outwardly and a support rod connected vertically to the bottom surface of the support plate. The lower end of the support rod extends downwardly below the platform. The application achieves the fixation of the door leaf during pouring by adjusting the contact between the clamping plates and the door leaf. However, the contact area between the clamping plates and the door leaf is small, and the clamping and supporting effect provided by the clamping plates at the edge of the door leaf is limited, making it difficult to prevent the door leaf from deforming or collapsing locally due to the gravity of the concrete during pouring. Therefore, the device cannot guarantee the size and shape precision of the final product, and it is difficult to provide effective clamping and support for the door leaf during concrete pouring.
