The inserting block 2 and the inserting slot 3 are symmetrically distributed at both ends of the splicing formwork support 1. The connecting component includes a bolt slot 4, a nut slot 5, an installation slot 6, a bolt 7 and a nut 8. The bolt slot 4 and the nut slot 5 are opened on the inner bottom wall of the splicing formwork support 1, and the bolt slot 4 penetrates through the nut slot 5. The bolt slot 4 is communicated with the nut slot 5. The installation slot 6 is opened on the inner bottom wall of the splicing formwork support 1 near the bolt slot 4. The bolt 7 is located in the installation slot 6, and the bolt 7 penetrates through the installation slot 6 and extends to the outside of the splicing formwork support 1. The nut 8 is threadedly connected to the bolt 7;

[0025] The bolt 7 is matched with the bolt slot 4, and the nut 8 is matched with the nut slot 5.

[0026] Through the above technical solution, during splicing, the insertion block 2 at one end of a splicing formwork 1 is inserted into the slot 3 at one end of another splicing formwork 1. The two adjacent splicing formworks 1 are spliced together through the insertion block 2 and the slot 3. Then, the nut 8 is placed into the nut groove 5 at one end of a splicing formwork 1, and the bolt 7 at one end of another splicing formwork 1 is rotated until it is inserted into the bolt groove 4. By rotating the bolt 7, the bolt 7 moves towards the direction of the nut 8 and is threadedly connected to the nut 8. When the bolt 7 cannot be rotated anymore, the fixation of the two spliced splicing formworks 1 is completed.

[0027] Embodiment 2:

[0028] Different from Embodiment 1, as shown in Figures 4 - 6 shown, the connecting component includes a first connecting block 9, a second connecting block 10, a first connecting groove 11, a second connecting groove 16 and a rotating rod 12. The first connecting groove 11 and the second connecting groove 16 are respectively opened at positions close to the middle at both ends of the splicing formwork 1. The first connecting block 9 and the second connecting block 10 are respectively rotatably connected to the first connecting groove 11 and the second connecting groove 16, and the rotating rod 12 is connected to the first connecting block 9 and the second connecting block 10;

[0029] Both the first connecting block 9 and the second connecting block 10 are semi-circular structures, and the rotating directions of the first connecting block 9 and the second connecting block 10 are opposite, and the rotation angle of the first connecting block 9 and the second connecting block 10 is 90 degrees;

[0030] An arc-shaped groove 13 communicating with the first connecting groove 11 and the second connecting groove 16 is opened on the inner bottom wall of the splicing formwork 1. One end of the rotating rod 12 connected to the first connecting block 9 and the second connecting block 10 passes through the arc-shaped groove 13, and the arc-shaped groove 13 facilitates the rotating rod 12 to drive the first connecting block 9 and the second connecting block 10 to rotate;

[0032] A limiting groove 19 communicating with the first connecting groove 11 and the second connecting groove 16 is opened at a position on the inner bottom wall of the splicing formwork 1 close to the arc-shaped groove 13. A first limiting rod 17 and a second limiting rod 18 matching the limiting groove 19 are respectively fixed on the first connecting block 9 and the second connecting block 10. The first connecting block 9 and the second connecting block 10 limit the adjacent two splicing formworks 1 by the first limiting rod 17 and the second limiting rod 18 entering the limiting groove 19.

[0033] Through the above technical solution, during splicing, the insertion block 2 at one end of a splicing formwork 1 is inserted into the slot 3 at one end of another splicing formwork 1. The two adjacent splicing formworks 1 are spliced together through the insertion block 2 and the slot 3. Then, the rotating rod 12 is rotated, and the first connecting block 9 is driven to rotate towards the second connecting groove 16 by the rotation of the rotating rod 12, while the second connecting block 10 rotates towards the first connecting groove 11 until a part of the first connecting block 9 and the second connecting block 10 respectively enter the second connecting groove 16 and the first connecting groove 11. Then, the screw 14 is rotated to drive the pressing plate 15 to move downward and press tightly against the inner bottom wall of the splicing formwork 1, so that the first connecting block 9 and the second connecting block 10 can be fixed in the rotated position, thereby realizing the splicing and fixing of two adjacent splicing formworks 1.
