[0028] Fixed parts 3 are installed on the surfaces of the two long boards 1 and are connected to the two short boards 2;

[0029] The fixing member 3 includes two plate bodies 31 fixedly installed on the surface of the long board 1. Threaded rods 32 are slidably installed on both sides of the two plate bodies 31. The opposite ends of the two threaded rods 32 penetrate through the hole parts on the surface of the short board 2 and are threadedly installed with limit nuts 33. A storage member 30 for preventing the limit nut 33 from falling off is arranged on the surface of the threaded rod 32.

[0030] The storage member 30 includes a rod body 301 integrally processed on the surface of the threaded rod 32. A sliding groove 302 for the rod body 301 to slide is opened on the surface of the plate body 31. The surface of the rod body 301 is adapted to the limit nut 33;

[0031] In this embodiment, two long plates 1 are placed in parallel. The slot 5 on one side of the short plate 2 is inserted into the insertion plate 4 on one side of the long plate 1, forming a rectangle with the two long plates 1 and the two short plates 2. The threaded rod 32 in the plate body 31 slides through the hole in the short plate 2 and is threadedly installed with the limit nut 33 to complete the fixation. Pouring concrete into the rectangle is also convenient for disassembly. The limit nut 33 can be threadedly installed with the rod body 301 on the surface of the threaded rod 32 to fix the threaded rod 32 and prevent it from sliding in the plate body 31. At the same time, it can provide anti-loosening protection for the limit nut 33. When it needs to be removed, the threaded rod 32 is separated from the limit nut 33. Use a tool to rotate the adjustment nut 9 to drive the adjustment rod 82 to rotate, so that the sealing disc 83 is pushed out of the short plate 2, extruding the formed concrete, separating the short plate 2 from the concrete, and facilitating its removal.

[0032] Insertion plates 4 are fixedly installed on both sides of the two long plates 1, and slots 5 for the insertion plates 4 to be inserted are provided on one adjacent side of the two short plates 2;

[0033] Specifically, the two long plates 1 are placed in parallel, and the slot 5 on one side of the short plate 2 is inserted into the insertion plate 4 on one side of the long plate 1, forming a rectangle with the two long plates 1 and the two short plates 2, which has the function of guiding installation.

[0034] Limit blocks 6 are integrally processed on the tops of the two long plates 1, and limit slots 7 for the limit blocks 6 to be inserted are provided at the bottoms of the two long plates 1;

[0035] Furthermore, the limit block 6 on the top of the long plate 1 is adapted to the limit slot 7 at the bottom of the long plate 1, so as to achieve the effect of stacking and placing.

[0036] It also includes a pushing member 8 installed inside the short plate 2. The pushing member 8 includes a tube body 81 embedded in the short plate 2. An adjustment rod 82 is threadedly installed inside the tube body 81, and a sealing disc 83 is rotatably installed at one end of the adjustment rod 82;

[0037] Among them, use a tool to rotate the adjustment nut 9 to drive the adjustment rod 82 to rotate, so that the sealing disc 83 is pushed out of the short plate 2, extruding the formed concrete, separating the short plate 2 from the concrete, and facilitating its removal.

[0038] An adjustment nut 9 is integrally processed at one end of the adjustment rod 82, and a limit ring 10 is integrally processed on the surface of the sealing disc 83. One side of the limit ring 10 is in contact with one side of the tube body 81;

[0039] It should be noted that when one side of the limit ring 10 is in contact with the surface of the tube body 81, the other side of the limit ring 10 is flush with the surface of the short plate 2, so as to ensure that the concrete is formed more smoothly.

[0040] Reinforcing rods 11 are fixedly installed on the opposite sides of the two long plates 1;

[0041] Among them, the reinforcing rod 11 is arranged on the surface of the long board 1, aiming to prevent the long board 1 from being bent.

[0042] The two long boards 1 of this device are placed in parallel. The slot 5 on one side of the short board 2 is inserted into the insertion board 4 on one side of the long board 1, forming a rectangle with the two long boards 1 and the two short boards 2. And the threaded rod 32 in the plate body 31 slides through the hole part in the short board 2 and is threadedly installed with the limit nut 33 to complete the fixation. Pouring concrete into the rectangle is also convenient for disassembly. Among them, the limit nut 33 can be threadedly installed with the rod body 301 on the surface of the threaded rod 32 to fix the threaded rod 32 and prevent it from sliding in the plate body 31. At the same time, it can provide anti-disengagement protection for the limit nut 33. When it needs to be removed, the threaded rod 32 is separated from the limit nut 33, and the adjusting nut 9 is rotated by a tool to drive the adjusting rod 82 to rotate, so that the sealing disc 83 is pushed out of the short board 2, extruding the formed concrete, separating the short board 2 from the concrete, and facilitating its removal.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
