[0036] In use, the application is first installed by clamping the clamping plate 204 inside the clamping slot 203, which is beneficial for the vertical splicing of the side plate and the bottom plate 1, and facilitates subsequent disassembly and transportation. The two side plates 201 facilitate the installation of the two baffle plates 202, thereby forming a rectangular structure, facilitating the pouring of concrete and the forming of the plate, and facilitating the pouring of concrete. After the baffle plate 202 is positioned between the two side plates 201, the bolt 301 is rotated, the bolt 301 drives the sliding block 304 to slide, the two drive grooves 303 on the sliding block 304 abut the two protrusions 305, the protrusions 305 drive the clamping pin 302 to extend into the lock slot 307, thereby making the baffle plate 202 and the side plate 201 firmly installed, facilitating the pouring of concrete. The side plate 201 is provided with a plurality of lock slots 307, which facilitates the adjustment of the position of the baffle plate 202, is beneficial for pouring plates of different lengths, and facilitates the disassembly of the two side walls. After the two side walls are disassembled, the screw nut 703 is driven by the wrench, which is beneficial for the screw rod 701 to drive the push plate 702 under the action of the screw thread, so that the push plate 702 abuts the poured plate, which is beneficial for facilitating the stripping and unloading work, and the operation is more convenient and labor-saving. After the position of the baffle plate 202 is adjusted, the push plate 702 is adjusted by sliding, thereby facilitating the fine adjustment work, facilitating the pouring and forming work of the plate of specified length, facilitating the installation of the three fixing frames 401, facilitating the placement of the bottom plate 1, and facilitating the placement of multiple bottom layers, so that multiple plates have gaps, facilitating subsequent lifting work, and the operation is more convenient. The installation of the fixing block 402 facilitates the connection of the positioning plate 403, and the positioning plate 403 has elasticity under the action of the connecting block 406 and the movable spring 407. When the side plate 201 is spliced with the bottom plate 1, the top plate 404 on the fixing frame 401 is inserted into the fixing block 402, which is beneficial for the stable connection of the side plate 201 and the bottom plate 1. After the top plate 404 is inserted into the fixing block 402, the top plate 404 drives the positioning plate 403 to slide out of the action of the movable spring 407. When the other top plate 404 of the baffle plate 202 is stacked, the positioning plate 403 can be inserted into the insertion slot 405 at the bottom of the fixing frame 401, thereby making the multiple bottom plates 1 stacked firmly and stably. The installation of the handle 501 facilitates the lifting and stacking of the bottom plate 1. The connecting spring 502 facilitates the elasticity of the handle 501, facilitates the storage of the handle 501, and facilitates the elasticity of the limiting block 602 under the action of the abutting spring 603. The limiting block 602 always abuts the inside of the fixing frame 401. After the handle 501 slides to a certain position, the limiting block 602 slides into the limiting slot 601 under the action of the abutting spring 603, thereby facilitating the limiting of the handle 501 and preventing it from sliding out. The limiting slot 601 and the limiting block 602 are both trapezoidal structures, and the handle 501 can slide back when it is pushed for storage.
