Description

Technical Field

[0001] This utility model relates to the field of floodproof door technology, and in particular to a prefabricated assembled subway floodproof door structure. Background Technology

[0002] Subway floodgates are facilities used in subway stations to prevent flooding. They are usually installed at the entrance of the subway station or the exit of the underground passage to prevent the interior of the subway station from being flooded by floods, rainstorms or other flood events.

[0003] The design and installation steps for floodgates generally include the following: determining requirements and design schemes, site preparation, installing the frame and support structure, installing waterproof sealing materials, installing the control system, debugging and testing, and improving signage and emergency plans. The frame installation process involves a large amount of welding work. The floodgate frame can be initially divided into the keel, panels, and connectors. There are generally two existing installation methods for floodgates: the first is to manufacture the complete door leaf in the factory and transport it to the site for installation. Due to the large size and weight of the door leaf, transportation and installation are inconvenient. The second method is to use a modular assembly approach, transporting the keel and secondary components of the door leaf to the site, connecting the various components into a whole through welding, and finally connecting the floodgate to the main concrete structure using pre-installed connectors. Because subway floodgates are often installed in high-traffic, important transfer locations, the extensive welding work leads to excessively long installation times, affecting the normal operation of the subway and causing significant trouble for the operating unit. Utility Model Content

[0017] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0018] Please refer to Figures 1 to 4A prefabricated subway floodproof door structure includes four main poles 11, several long poles 12, and multiple crossbars 13. The four main poles 11 form a rectangular frame 10. The long poles 12 are fixed at intervals inside the frame 10. The crossbars 13 are spaced between two long poles 12. Several panels 20 are provided on both sides of the frame 10. The panels 20 cover the surface of the frame 10. The edges of the panels 20 are riveted to the corresponding long poles 12, crossbars 13, and main poles 11. Aluminum strips 21 are embedded between the panels 20. A sealing plate 14 is provided around the frame 10.

[0019] The main pole 11, long pole 12, cross pole 13, and panel 20 are disassembled and transported to a designated location. Then, the main pole 11, long pole 12, and cross pole 13 are assembled sequentially at the designated location to form an overall frame. The panel 20 is then fixed to the surface of the long pole 12 and cross pole 13 by riveting. Aluminum strips 21 are embedded between the panels 20 to fill the gaps between them and achieve a sealing purpose. Furthermore, a sealing plate 14 is provided around the frame 10 formed by the main pole 11 to close the sides of the frame 10, forming an internally closed structure for the floodgate, which facilitates the blocking of water flow. Through the above structure, the various components are modularized, making it convenient to transport to the predetermined location for rapid assembly.

[0020] The above solution also includes a door hinge 30, which is fixed to the main rod 11 on one side of the frame 10. The door hinge 30 has a lug 31 on one side, and the lug 31 extends out of the sealing plate 14. A pin can be inserted into the lug 31 to make the flood door rotate and connect with the door frame, thereby realizing the opening or closing of the flood door.

[0021] Furthermore, two lifting rings 15 are provided at the top of the frame 10. The floodgate can be lifted as a whole through the lifting rings 15, and people can install the floodgate after the assembly is completed.

[0022] The main rod 11, long rod 12, and cross rod 13 are all made of I-beams, ensuring overall strength and simplifying processing. Both ends of the cross rod 13 protrude into the long rod 12, making the connection between the cross rod 13 and the long rod 12 tighter. The connection between the main rod 11 and the long rod 12, as well as between the long rod 12 and the cross rod 13, is fixed using L-shaped connectors 16. Connectors 16 ensure a vertical connection between the main rod 11 and the long rod 12, and also between the long rod 12 and the cross rod 13, ensuring stability. The L-shaped structure also allows for better fixed connections between the main rod 11 and the long rod 12, and between the long rod 12 and the cross rod 13.

[0023] The main poles 11 are connected by rectangular corner boxes 17. The corner boxes 17 are embedded in the two adjacent main poles 11 to ensure that the surface of the frame 10 is flat. The bottom surface of the corner boxes 17 is fixedly connected to the two main poles 11 by bolts, and the side surface of the corner boxes 17 is fixedly connected to the corresponding main poles 11 by bolts.

[0024] This utility model provides a prefabricated assembly-type subway floodproof door structure. The main pole, long poles, crossbars, and panels are disassembled and transported to a designated location. Then, the main pole, long poles, and crossbars are assembled sequentially at the designated location to form an overall frame. The panels are then fixed to the surfaces of the long poles and crossbars by riveting, and aluminum strips are embedded between the panels to fill the gaps and achieve a sealing purpose. A sealing plate is installed around the frame formed by the main poles to close the sides of the frame, forming a closed internal structure for the floodproof door, effectively blocking water flow. Through this structure, the various components are modularly arranged, facilitating rapid assembly at the designated location.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
