Composite floor slabs have good integrity, and the upper and lower surfaces of the slabs are flat, which facilitates the finishing layer decoration. They are suitable for high-rise buildings and large-span buildings with high requirements for overall rigidity.

Detailed Implementation

[0022] The present invention will be further described below with reference to embodiments.

[0023] Please see Figure 1-3 This invention provides a shear-force self-locking interlayer connection composite plate mold table, comprising: a base 1, with fixed shafts 2 fixedly connected to the four corners of the upper end of the base 1, and top plates 3 fixedly connected to the upper ends of the fixed shafts 2. The outer surfaces of the fixed shafts 2 are respectively fitted and slidably connected to the four corners of the lower frame 4 and the upper frame 5. Symmetrical connecting columns 8 are fixedly connected to the middle of the four sides of the lower frame 4 and the upper frame 5. Connecting plates 801 are fixedly connected to the outer sides of the connecting columns 8. Adjustable fixing straps 10 can be provided on both the upper and lower connecting columns 8. Fixed plates 7 are fixedly connected to the upper sides of the left and right ends of the outer surfaces of the lower frame 4 and the upper frame 5. Several threaded holes 701 are provided on one side of each fixed plate 7. Anti-deformation devices 9 can be threadedly connected to the threaded holes 701. Shear-force self-locking mechanisms 6 are fixedly connected to the lower sides of the left and right ends of the outer surfaces of the lower frame 4 and the upper frame 5.

[0024] Further as Figure 2 As shown, it is worth noting that the shear self-locking mechanism 6 includes a lower fixed block 601 and an upper fixed block 602. Both the lower fixed block 601 and the upper fixed block 602 have locking grooves 604 on opposite sides at their midpoints. Locking tongues 605 are slidably connected within the locking grooves 604. Sliding grooves 603 are provided on both sides of the locking grooves 604 on the lower fixed block 601 and the upper fixed block 602. Sliding blocks 613 are fixedly connected to the upper ends of both sides of the lower fixed block 601 and the upper fixed block 602. An elastic reset member 610 is provided within the locking grooves 604, and the elastic reset member 610 is connected to... Between the bottom of the sliding groove 603 and the sliding block 613, a shear self-locking mechanism 6 is used. When the main bodies of two adjacent mold platforms are assembled, during the process of the locking tongue 605 being inserted into the locking groove 604, the sliding block 613 slides in the sliding groove 603, and the spring is compressed. When the locking tongue 605 is fully inserted, the spring returns to its original position and pushes the locking tongue 605 deeper into the locking groove 604 through the sliding block 613, so that the locking block 608 and the locking groove 609 are accurately engaged. This achieves a fast and firm connection between layers, effectively withstands shear force, ensures the stability of the interlayer structure of the composite slab, and improves construction efficiency.

[0025] Further as Figure 2 As shown, it is worth noting that guide blocks 607 and guide grooves 606 are respectively provided at the upper and lower ends of the latch 605 and the lock groove 604. The guide block 607 is slidably connected in the guide groove 606, and the cross sections of the guide block 607 and the guide groove 606 are both regular polygons. The relative connection between the latch 605 and the lock groove 604 can be facilitated through the guide block 607 and the guide groove 606.

[0026] Further as Figure 2 As shown, it is worth noting that the elastic reset member 610 is a spring, which facilitates the return of the locking tongue 605.

[0027] This solution has the following working process: through the shear force self-locking mechanism 6, the guide block 607 is slidably connected in the guide groove 606, and the locking block 608 is engaged with the locking groove 609. When the main bodies of two adjacent mold tables are combined, during the process of the locking tongue 605 being inserted into the locking groove 604, the sliding block 613 slides in the sliding groove 603, and the spring is compressed. When the locking tongue 605 is fully inserted, the spring returns to its original position and pushes the locking tongue 605 deeper into the locking groove 604 through the sliding block 613, so that the locking block 608 is accurately engaged with the locking groove 609, realizing a fast and firm connection between layers. The adjustable fixing strap 10 is used to adjust the length according to different fixing requirements and hang on the connecting column 8 to achieve a firm fixation of the composite plate mold table. The two ends of the connecting hole 9031 of the rotating shaft 903 in the anti-deformation device 9 can be threaded to the outer surface of the first threaded shaft 9012 provided at both ends of the first connecting member 901 or the second threaded shaft 9023 provided at the other end of the second connecting member 902.

[0028] According to the above working process, when the main bodies of two adjacent mold platforms are combined, the locking tongue 605 is inserted into the locking groove 604 through the shear self-locking mechanism 6. During this process, the sliding block 613 slides in the sliding groove 603, and the spring is compressed. When the locking tongue 605 is fully inserted, the spring returns to its original position and pushes the locking tongue 605 deeper into the locking groove 604 through the sliding block 613, so that the locking block 608 and the locking groove 609 are accurately engaged. This achieves a fast and firm connection between layers, effectively withstands shear force, ensures the stability of the interlayer structure of the composite slab, and improves construction efficiency. The guide block 607 and the guide groove 606 facilitate the relative connection between the locking tongue 605 and the locking groove 604. The elastic reset member 610 facilitates the rebound of the locking tongue 605.

[0029] Further as Figure 2 As shown, it is worth noting that each side of the locking tongue 605 is provided with a locking block 608, and the corresponding end of the locking groove 604 is provided with a locking groove 609. The locking block 608 and the locking groove 609 engage with each other. The locking block 608 is hemispherical, and the locking groove 609 is a hemispherical groove. The diameter of the ball of the locking block 608 matches the diameter of the groove of the locking groove 609. Through the locking block 608 and the locking groove 609, a quick and firm connection between layers is achieved, which can effectively withstand shear force, ensure the stability of the interlayer structure of the composite slab, and improve construction efficiency.

[0030] Further as Figure 2As shown, it is worth noting that each side of the locking block 608 is fixedly connected to a first fixing post 611, the lower end of each first fixing post 611 is fixedly connected to a limiting block 6111, the outer surface of each limiting block 6111 is slidably connected to a limiting groove 6121 provided in the middle of the second fixing post 612, the lower end of each second fixing post 612 is fixedly connected to the bottom end of a sliding groove 603, and both the first fixing post 611 and the second fixing post 612 are located in the middle of the elastic reset member 610. Through the relative connection relationship and position of the first fixing post 611 and the second fixing post 612, the position and movement trajectory of the locking tongue 605 and the sliding block 613 can be restricted.

[0031] Further as Figure 1 As shown, it is worth noting that the adjustable fixing strap 10 is made of elastic material, such as rubber, and both ends of the adjustable fixing strap 10 are fixedly connected to hooks, which can be connected to the outer surface of the connecting column 8. The adjustable fixing strap 10 can be used to adjust the length according to different fixing requirements and hang on the connecting column 8 to achieve a firm fixation of the composite plate mold. During transportation, it can effectively prevent the mold from shaking or colliding, and avoid damage to the composite plate mold.

[0032] Further as Figure 3 As shown, it is worth noting that each set of anti-deformation devices 9 includes a first connecting member 901, two second connecting members 902, and two rotating shafts 903. Each first connecting member 901 has a groove 9011 on one side of its middle portion, and both ends of the first connecting member 901 are fixedly connected to a first threaded shaft 9012. Each second connecting member 902 has a groove 9021 on one end, and one side of the groove 9021 is threadedly connected to a threaded hole 701 via a threaded bolt 9022. The other end of each second connecting member 902 is fixedly connected to a second threaded shaft 9023. The rotating shaft 903 has a connecting hole 9031 in its middle portion, and the two sides of the connecting hole 9031... Both ends of the rotating shaft 903 in the anti-deformation device 903 can be threaded to the outer surface of the first threaded shaft 9012 at both ends of the first connector 901 or the second threaded shaft 9023 at the other end of the second connector 902, thereby achieving a firm fixation of the composite plate mold table. Both ends of the connecting hole 9031 of the rotating shaft 903 in the anti-deformation device 9 can be threaded to the outer surface of the first threaded shaft 9012 at both ends of the first connector 901 or the second threaded shaft 9023 at the other end of the second connector 902, thereby enhancing the anti-deformation ability of the mold table body, effectively improving the stability of the mold table body during use, transportation and stacking, and ensuring the quality of the composite plate.

[0033] In summary: Through the shear-locking mechanism 6, the guide block 607 slidingly connected within the guide groove 606, and the locking block 608 engaging with the locking groove 609, during the assembly of adjacent mold bodies, as the locking tongue 605 inserts into the locking groove 604, the sliding block 613 slides within the sliding groove 603, compressing the spring. When the locking tongue 605 is fully inserted, the spring returns to its original position, pushing the locking tongue 605 deeper into the locking groove 604 via the sliding block 613, ensuring accurate engagement between the locking block 608 and the locking groove 609. This achieves a rapid and secure connection between layers. The adjustable fixing strap 10, with its length adjusted according to different fixing requirements and hung on the connecting column 8, securely fixes the composite plate mold. Both ends of the connecting hole 9031 of the rotating shaft 903 in the anti-deformation device 9 can be threaded to the outer surface of the first threaded shaft 9012 at both ends of the first connecting member 901 or the second threaded shaft 9023 at the other end of the second connecting member 902. Through the locking block 608 and the locking groove 609, this achieves... The rapid and robust interlayer connection effectively withstands shear forces, ensuring the stability of the interlayer structure of the composite slab and improving construction efficiency. The relative connection and position of the first fixing column 611 and the second fixing column 612 restrict the position and movement trajectory of the locking tongue 605 and the sliding block 613. The adjustable fixing strap 10, with its length adjusted according to different fixing requirements, is hung on the connecting column 8 to achieve a secure fixation of the composite slab formwork. This effectively prevents the formwork from shaking or colliding during transportation, avoiding damage to the composite slab formwork. By achieving a secure fixation of the composite slab formwork, both ends of the connecting hole 9031 of the rotating shaft 903 in the anti-deformation device 9 can be threaded to the outer surface of the first threaded shaft 9012 at both ends of the first connecting member 901 or the second threaded shaft 9023 at the other end of the second connecting member 902, thereby enhancing the deformation resistance of the formwork body and effectively improving the stability of the formwork body during use, transportation, and stacking, ensuring the quality of the composite slab.
