DETAILED DESCRIPTION

[0028] The following will be combined with the Figures 1-4 The application is further described in detail.

[0029] Please refer to Figures 1-3 A gap filling mechanism at the joint of prefabricated composite board and floor formwork, comprising a floor formwork body 1 and a composite board body 2, a sealing structure for filling the gap is arranged between the floor formwork body 1 and the composite board body 2, an adjusting assembly for preventing collision is arranged on the composite board body 2, the adjusting assembly comprises an L type connecting plate 3, a clamping plate 4, a through slot 5, a threaded rod 6, a rotating disc 7, a moving block 8 and a pulley 9.

[0030] The L type connecting plate 3 is provided with two on both sides of the composite board body 2 respectively, the clamping plate 4 is provided with two on the lower surface of the L type connecting plate 3 respectively, the through slot 5 is provided with two vertically arranged on the side wall of the L type connecting plate 3 respectively, the threaded rod 6 is provided with two in the through slot 5 respectively, the bottom end of the threaded rod 6 is rotationally connected with the bottom wall of the through slot 5, the top end of the threaded rod 6 penetrates the top wall of the through slot 5 and forms a rotating connection, the rotating disc 7 is fixedly connected with the top end of the threaded rod 6, for rotating the threaded rod 6, the moving block 8 is provided with two fixedly connected with the side wall of one side of the two clamping plates 4 close to the L type connecting plate 3 respectively, the moving block 8 is located in the through slot 5 and is threadedly connected with the threaded rod 6, the pulley 9 is provided with two groups, each group is provided with two, each group of pulleys 9 is mounted on the bottom end of the L type connecting plate 3 respectively.

[0031] In use, the composite slab body 2 is hoisted and moved above the floor formwork body 1. Then, L-shaped connecting plates 3 are placed on both sides of the composite slab body 2, so that the two sides of the composite slab body 2 are respectively located between the L-shaped connecting plates 3 and the clamping plates 4. Then, the threaded rod 6 is rotated by the rotating disk 7, so that the clamping plates 4 move upward in the through groove 5, and the two L-shaped connecting plates 3 are fixed on both sides of the composite slab body 2. Then, the composite slab body 2 is placed downward, so that the pulley 9 abuts against the floor formwork body 1. The position of the composite slab body 2 is adjusted by the pulley 9 to align the composite slab body 2 with the floor formwork body 1. Then, the L-shaped connecting plates 3 are removed and the composite slab body 2 is installed. This process avoids the problem of the edges and corners of the composite slab colliding with the floor formwork when adjusting the position of the composite slab, which could cause damage to the edges and corners.

[0032] Reference Figure 1 The sealing structure includes a U-shaped sealing strip 10, which is attached to the upper surface of the floor formwork body 1 and adapted to the composite slab body 2. After the composite slab body 2 is placed on the floor formwork body 1, the sealing strip 10 is positioned between the composite slab body 2 and the floor formwork body 1. By pressing down on the sealing strip 10, the composite slab body 2 can fill the gap between the composite slab body 2 and the floor formwork body 1, preventing concrete from seeping into the gap between the composite slab body 2 and the floor formwork body 1 during concrete pouring, thus affecting the quality of the project and increasing the burden of subsequent cleaning work.

[0033] Reference Figure 1 A buffer spring 11 is provided between the pulley 9 and the L-shaped connecting plate 3. The two ends of the buffer spring 11 are fixedly connected to the L-shaped connecting plate 3 and the pulley 9 respectively. The buffer spring 11 can reduce the impact force of the pulley 9 when it comes into contact with the floor template body 1, and prevent damage to the floor template body 1 or the pulley 9.

[0034] Reference Figure 4 Each buffer spring 11 is equipped with a telescopic rod 12. The two ends of the telescopic rod 12 are fixedly connected to the L-shaped connecting plate 3 and the pulley 9, respectively. The telescopic rod 12 can restrict the buffer spring 11 to prevent the buffer spring 11 from bending and causing the pulley 9 to swing, which would affect the use of the pulley 9.

[0035] Reference Figure 3 Rubber pads 13 are fixedly connected to the lower surface of the L-shaped connecting plate 3 above the clamping plate 4. When the clamping plate 4 clamps the composite plate body 2, the rubber pads 13 are squeezed to increase the friction between the L-shaped connecting plate 3 and the composite plate body 2, thereby increasing the clamping force on the composite plate body 2 and preventing the composite plate body 2 from moving between the L-shaped connecting plate 3 and the clamping plate 4 when the L-shaped connecting plate 3 moves, which would prevent the composite plate body 2 from moving.

[0036] With reference to Figure 3 The upper surface of the clamping plate 4 is rotatably connected with a plurality of rolling balls 14. When the L-shaped connecting plate 3 is removed, the rolling balls 14 can reduce the friction between the clamping plate 4 and the laminated slab body 2, so that the laminated slab body 2 is prevented from being pressed on the clamping plate 4 after the clamping plate 4 is lowered, thereby making it difficult to pull out the L-shaped connecting plate 3.

[0037] With reference to Figure 3 The side wall of the L-shaped connecting plate 3 is provided with a guide groove 15 on both sides of the through groove 5, and the guide groove 15 is fixedly connected with a guide rod 16. The side wall of the clamping plate 4 close to the L-shaped connecting plate 3 is fixedly connected with two guide blocks 17, and the guide blocks 17 are respectively located in the guide grooves 15 and are sleeved on the guide rods 16. The cooperation of the guide grooves 15, the guide rods 16 and the guide blocks 17 can improve the stability of the lifting of the clamping plate 4, so that the clamping plate 4 is prevented from shaking when the threaded rod 6 is rotated.

[0038] The implementation principle of the present application is as follows: in use, the laminated slab body 2 is hoisted and moved above the floor formwork body 1, and then the L-shaped connecting plate 3 is placed on both sides of the laminated slab body 2, so that both sides of the laminated slab body 2 are located between the L-shaped connecting plate 3 and the clamping plate 4. Then the threaded rod 6 is rotated by the rotating disc 7, so that the clamping plate 4 moves upward in the through groove 5, and the two L-shaped connecting plates 3 are fixed on both sides of the laminated slab body 2. Then the laminated slab body 2 is placed downward, so that the pulley 9 abuts against the floor formwork body 1. The position of the laminated slab body 2 is adjusted by the pulley 9, so that the laminated slab body 2 is aligned with the floor formwork body 1. At the same time, the impact force of the pulley 9 on the floor formwork body 1 can be reduced by the buffer spring 11, so that the floor formwork body 1 or the pulley 9 is prevented from being damaged. Then the L-shaped connecting plate 3 is removed. When the L-shaped connecting plate 3 is removed, the rolling balls 14 can reduce the friction between the clamping plate 4 and the laminated slab body 2, so that the laminated slab body 2 is prevented from being pressed on the clamping plate 4 after the clamping plate 4 is lowered, thereby making it difficult to pull out the L-shaped connecting plate 3. The laminated slab body 2 is installed, so that the sealing rubber strip 10 is located between the laminated slab body 2 and the floor formwork body 1. The gap between the laminated slab body 2 and the floor formwork body 1 is filled by the laminated slab body 2 pressing the sealing rubber strip 10, so that the concrete is prevented from seeping into the gap between the laminated slab body 2 and the floor formwork body 1 when the concrete is poured, thereby affecting the engineering quality and increasing the burden of the later cleaning work. The problem that the edges and corners of the laminated slab are easily collided with the floor formwork when the position of the laminated slab is adjusted, thereby causing the edges and corners to be damaged is avoided.

Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features thereof can be replaced equivalently.
