[0023] Example 1

[0024] See also Figure 1-Figure 2The utility model provides a technical solution: a new type of composite floor for construction, comprising: a floor body 1, a plurality of triangular steel bars 2 are arranged on the upper surface of the floor body 1, the triangular steel bars 2 are arranged in rows, the upper surface of each row of triangular steel bars 2 is connected with a metal rod 3, the metal rod 3 can connect the triangular steel bars 2 in each row together, a locking device 6 is provided between each two floor bodies 1, the locking device 6 is used to connect adjacent floor boards together, the locking device 6 includes a first mounting block 8, a second mounting block 11, a threaded rod 12 and a crank assembly 17, the first mounting block 8 and the second mounting block 11 are both mounted on On the upper surface of the floor body 1, two first mounting blocks 8 are installed on one side of the floor body 1, and two second mounting blocks 11 are installed on the other side of the floor body 1. A threaded rod 12 is installed between the first mounting block 8 and the second mounting block 11. The threaded rod 12 connects the two mounting blocks and tightens them. A crank is set at one end of the threaded rod 12, and the crank device can drive the threaded rod 12 to rotate. A protruding plate 4 is provided at one end of the floor body 1, and a recessed plate is provided at the other end of the floor body 1. The protruding plate 4 and the recessed plate are adapted to each other, and the protruding plate of one floor body 1 can be inserted into the recessed plate of another floor body 1.

[0025] In actual use, adjacent floor slab bodies 1 can be tightened by the threaded rod 12, and the threaded rod 12 can be driven to rotate by turning the crank assembly 17. The rotation of the threaded rod 12 will drive the second mounting block 11 threadedly connected to the threaded rod 12 to move toward the direction of the crank assembly 17. The second mounting block 11 is installed on the floor slab body 1, so turning the handle 20 can fit the two floor slabs tightly together.

[0026] Example 2

[0027] See also Figure 2-Figure 4On the basis of embodiment 1, an annular groove 9 is opened on one side of the first mounting block 8, and a first through hole 10 is opened in the annular groove 9. The annular groove 9 and the first through hole 10 pass through the first mounting block 8 together. One end of the threaded rod 12 passes through the annular groove 9 and the first through hole 10 and is slidably connected to the first through hole 10. The surface of the threaded rod 12 is provided with a thread. The other end of the threaded rod 12 passes through the second mounting block 11 of the other floor plate body 1 and is threadedly connected with it. Therefore, the rotation of the threaded rod 12 can drive the movement of the second mounting block 11, so that it drives the floor plate body 1 to move, so that the two floor plate bodies 1 can be tightly fitted together and not easy to loosen. A rotating disk 13 is fixedly installed, and the rotating disk 13 is used to limit the threaded rod 12 from moving relative to the first mounting block 8. Only in this way can a certain force be generated to allow the second mounting block 11 to move toward the first mounting block 8. The threaded rod 12 passes through the rotating disk 13 and is fixedly connected thereto. Therefore, the fixed position of the rotating disk 13 is the fixed position of the threaded rod 12. The rotating disk 13 is embedded in the annular groove 9 and is rotatably connected thereto. The rotating disk 13 will rotate in the annular groove 9 as the threaded rod 12 rotates. A plurality of balls 14 are provided on one side surface of the rotating disk 13. The presence of the balls 14 reduces the friction between the rotating disk 13 and the annular groove 9, making it more labor-saving to rotate it manually.

[0028] During actual use, the threaded rod 12 is rotated by the handle 20, and the rotation of the threaded rod 12 will cause the rotating disk 13 to be stuck in the annular groove 9. Finally, after the rotating disk 13 is completely stuck in the annular groove 9, the threaded rod 12 is rotated again, and the second mounting block 11 will be slightly tightened toward the first mounting block 8 along with the threaded rod 12. During the rotation process, the rotating disk 13 will rotate together, and the existence of the rotating disk 13 makes the threaded rod 12 no longer have obvious displacement relative to the first mounting block 8, only the other floor slab body 1 is tightened toward the floor slab body 1 where the first mounting block 8 is located.

[0029] Example 3

[0030] See also Figure 4-Figure 5On the basis of the second embodiment, a rectangular groove 15 is opened on one side of the threaded rod 12, and the handle 20 assembly includes a rectangular column 18, a rocker 19 and the handle 20. The rectangular column 18 extends into the rectangular groove 15 and is slidably connected thereto. Because of the existence of the rectangular groove 15, the rotation of the rectangular column 18 can drive the rotation of the threaded rod 12. One end of the rocker 19 is fixedly connected to one end of the rectangular column 18. The rotation of the rocker 19 can drive the rotation of the rectangular column 18. The first end of the handle 20 is fixedly connected to one end of the rocker 19. The rotation of the handle 20 can drive the rotation of the rocker 19. Therefore, the rotation of the handle 20 of the crank device can be To drive the rotation of the threaded rod 12, a rotating cylinder 21 is sleeved on the handle 20. The rotating cylinder 21 is used to prevent the handle 20 from grinding the hand during the rotation process. The rotating cylinder 21 is rotatably connected to the handle 20. During the rotation of the handle 20, the rotating cylinder 21 also rotates, and relative rotation occurs between the rotating cylinder 21 and the handle 20. An anti-wear disc 22 is provided at one end of the rotating cylinder 21. The anti-wear disc 22 is provided to prevent the tiger's mouth of the hand from rubbing against the rocker during the rotation process. The anti-wear disc 22 is sleeved on one end of the handle 20 and is rotatably connected to the handle 20. One side of the anti-wear disc 22 is slidably connected to the rocker 19.

[0031] In actual use, adjacent floor slab bodies 1 can be tightened by the threaded rod 12, and the threaded rod 12 can be driven to rotate by turning the crank assembly 17. When the handle 20 is turned, a rotating cylinder 21 is sleeved on the handle 20. The rotating cylinder 21 prevents the handle 20 from rubbing the hand during the rotation. The rotating cylinder 21 is rotatably connected to the handle 20. During the rotation of the handle 20, the rotating cylinder 21 also rotates accordingly, and relative rotation occurs between the rotating cylinder 21 and the handle 20. The rotation of the threaded rod 12 will drive the second mounting block 11 threadedly connected to the threaded rod 12 to move toward the direction of the crank assembly 17, and the second mounting block 11 is installed on the floor slab body 1, so turning the handle 20 can tightly fit the two floor slabs together.
