Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0025] See also Figures 1-8 , an underground civil air defense engineering aluminum formwork combined steel bar structure, including multiple plate bodies 2 connected to the outer wall of the steel bar frame 1, a T-shaped pressure plate 3 is connected between two adjacent plate bodies 2, the outer wall of the longitudinal plate of the T-shaped pressure plate 3 is fixedly connected with a sealing gasket 4, and multiple groups of clamping grooves 24 are provided on the T-shaped pressure plate 3, each group of clamping grooves 24 is symmetrically arranged, and each group of clamping grooves 24 is slidingly connected with a symmetrically arranged clamping plate 13, the outer wall of the clamping plate 13 is fixedly connected with a second threaded rod 27, the outer wall of the T-shaped pressure plate 3 is fixedly connected with multiple groups of symmetrically arranged side plates 25, the second threaded rod 27 passes through the side plate 25 and is threadedly connected to a second threaded ring 28 at one end, the inner wall of the clamping plate 13 is fixedly connected with an extrusion pad 26, and the outer wall of the extrusion pad 26 is against the inner wall of the plate body 2.
[0026] The aluminum formwork combined with steel bar structure of underground civil air defense engineering in the present invention, when two adjacent plate bodies 2 are installed, after the release agent is applied, the T-shaped pressure plate 3 can be clamped between the two plate bodies 2. At this time, the sealing gaskets 4 at the ends of the two T-shaped pressure plates 3 will be against the inner wall of the plate body 2. When the two T-shaped pressure plates 3 are installed, the sealing gaskets 4 can seal the inner walls of the two plate bodies 2, thereby avoiding the problem of slurry leakage, and the horizontal plate of the T-shaped pressure plate 3 is located on the outer wall of the two plate bodies 2 to prevent slurry leakage again;
[0027] At this time, in order to connect the two plate bodies 2 more tightly, the splint 13 can be pushed to move in the clamping groove 24, and at the same time, the second threaded rod 27 can be driven to move in the side plate 25. When the extrusion pad 26 on the inner wall of the splint 13 is against the inner wall of the plate body 2, the second threaded ring 28 can be rotated so that the bottom surface of the second threaded ring 28 is against the outer wall of the side plate 25. In this way, the splint 13 can apply an extrusion force to the plate body 2, making the plate body 2 and the sealing gasket 4 more tightly connected, further avoiding the leakage problem.
[0028] As a preferred solution of the present invention, a support structure is connected between two adjacent T-shaped pressure plates 3, and the support structure includes multiple extension plates 5. The outer walls of the two adjacent T-shaped pressure plates 3 are fixedly connected to multiple groups of extension plates 5, and each group of extension plates 5 is symmetrically arranged. The outer wall of the plate body 2 is connected to the bottom plate 6, and the top of the bottom plate 6 is fixedly connected to the support plate 10. The inner side of the support plate 10 is rotatably connected to multiple support components rotatably connected to the extension plates 5.
[0029] Specifically, in order to make the support of the plate body 2 more stable during installation, multiple support components and the bottom plate 6 can be supported to make the installation of the plate body 2 more stable.
[0030] As a preferred solution of the present invention, multiple support assemblies include a first strut 11 and a second strut 12, the first strut 11 is located inside the second strut 12 and is slidably connected thereto, the inner wall of the support plate 10 is fixedly connected to a second U-shaped plate 23, multiple first struts 11 are respectively rotatably connected to the inner wall of the second U-shaped plate 23, and multiple second struts 12 are respectively rotatably connected to multiple groups of extension plates 5.
[0031] Specifically, when the plate body 2 needs to be supported, multiple first struts 11 are slid in the second struts 12, so that the support distance between the first struts 11 and the second struts 12 in the multiple support assemblies is adjusted to a suitable position. Then, during adjustment, the multiple first struts 11 rotate in the second U-shaped plate 23 on the inner wall of the base plate 6, and the multiple second struts 12 rotate in the corresponding first U-shaped plates 19 respectively, which makes it convenient to adjust the distance of multiple groups of support assemblies.
[0032] As a preferred solution of the present invention, a protrusion 15 is fixedly connected to the end of the extension plate 5, a slot 16 is opened in the protrusion 15, an insert plate 18 is inserted between two adjacent slots 16, and the outer wall of the insert plate 18 is fixedly connected to the first U-shaped plate 19, and multiple second support rods 12 are respectively rotatably connected to the corresponding first U-shaped plates 19.
[0033] Specifically, in order to facilitate the overall disassembly and installation, the insert plate 18 can be removed from the slot 16 in the protrusion 15 at the end of the extension plate 5, so that the second support rod 12 can be separated from the extension plate 5, which can facilitate subsequent installation, disassembly and reuse;
[0034] The slot 16 and the plug-in board 18 are both T-shaped in design, which can prevent them from being separated after being plugged in, thereby ensuring structural stability.
[0035] As a preferred solution of the present invention, the outer wall of the plug plate 18 is connected to an extrusion assembly, which includes a fixed sleeve 17. The outer wall of the plug plate 18 is fixedly connected to the fixed sleeve 17, and a telescopic rod 20 is slidably connected inside the fixed sleeve 17. The outer sleeves of the telescopic rod 20 and the fixed sleeve 17 are provided with springs 29.
[0036] Specifically, when the plug board 18 is installed, the telescopic rod 20 can be pressed against the inner wall of the plate body 2. Since the telescopic rod 20 slides in the fixed sleeve 17, the spring 29 can press the telescopic rod 20 against the inner wall of the plate body 2, which again plays a stabilizing role.
[0037] As a preferred solution of the present invention, a movable groove 21 is opened on the outer wall of the second support rod 12, and a first threaded rod 30 is fixedly connected to the outer wall of the first support rod 11.

The movable groove 21 is located on the outer side of the movable groove 21 and one end is threadedly connected to a first threaded ring 22. The bottom surface of the first threaded ring 22 is against the top surface of the second support rod 12.
[0038] Specifically, when the first strut 11 and the second strut 12 need to be adjusted, the first threaded ring 22 can be rotated so that it rotates with the first threaded rod 30, so that the bottom surface of the first threaded ring 22 is loosened from the top surface of the second strut 12, so that the first strut 11 and the second strut 12 can slide smoothly. When fixing is required, the first threaded ring 22 can be fixed to the first threaded rod 30, thereby completing the fixing of the first strut 11 and the second strut 12.
[0039] As a preferred solution of the present invention, mounting ears 8 are fixedly connected to the outer walls at both ends of the bottom plate 6 , and fastening screws 9 are inserted into the mounting ears 8 .
[0040] Specifically, a fastening screw 9 is set in the mounting ear 8, and the base plate 6 can be installed on the ground through the mounting ear 8 using the fastening screw 9. The setting of the base plate 6 can prevent the settlement problem to a certain extent. On the other hand, the fastening screw 9 can facilitate the fixation of the base plate 6.
[0041] As a preferred solution of the present invention, a sliding groove 14 is provided on one side of the bottom plate 6 , and a slide plate 7 is fixedly connected to the other side. The slide plate 7 is slidably connected to the sliding groove 14 .
[0042] Specifically, when the base plate 6 is installed, the slide plate 7 can be slid into the slide groove 14, so that the separate base plates 6 can be connected into a whole, which further enhances the stability of the whole.
[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
