[0031] Further, the positioning piece one 5 comprises a positioning block one 51 arranged on the upper part of the unit block 1, and the lower part of the unit block 1 is provided with a positioning groove one 52, and the positioning block one 51 abuts inside the positioning groove one 52 of the lower part of the unit block 1;

[0032] The cooperation of the positioning block one 51 and the positioning groove one 52 can prevent the two unit blocks 1 from moving up and down, and the positioning block one 51 can be buckled inside the positioning groove one 52.

[0033] Further, the positioning piece two 6 comprises a positioning block two 61 arranged on the left and right sides of the unit block two 21, and the edge of the unit block 1 is provided with two positioning grooves two 62, and the positioning block two 61 slides inside the positioning groove two 62;

[0034] The positioning groove two 62 can provide a sliding space for the positioning block two 61, and the positioning block two 61 can prevent the unit block two 21 from moving in the horizontal position.

[0035] When using this device, firstly, multiple unit blocks 1 and 21 are spliced ​​from bottom to top, so that four unit blocks 1 and four unit blocks 21 form a template. The four unit blocks 1 are placed on the four right angles of a rectangle, and positioning blocks 2 61 are aligned with positioning slots 2 62. One unit block 2 21 is inserted between two unit blocks 1. After the template layer is assembled, traction is used to lock adjacent splicing rods 33 on the same side into the middle of adjacent splicing blocks 34. Then, the splicing rods 33 are pushed closer to unit blocks 1, and the screw 41 is rotated so that the turntable 42 is positioned in front of the splicing rod 33 near the connecting rod 32. Then, the turntable 42 is rotated, pushing the splicing rod 33 closer to unit blocks 1 and locking it in place. Therefore, it can... Unit block 21 and unit block 1 are spliced ​​together, and then the assembly begins upwards. First, the upper unit block 1 is assembled, so that the positioning block 51 of the lower unit block 1 is inserted into the positioning groove 52 of the lower unit block 1 and locked in place. Then, the same steps are used to splice unit block 1 and unit block 21. Repeating the above steps can complete the overall splicing of the template. In order to prevent unit block 21 from sticking to the pier when the template is demolded, and to prevent forced demolding from causing the surface of the pier to crack, an anti-stick layer 22 is set on the inner side of unit block 21, on the side that is in contact with the pier. By utilizing the smooth surface, high structural strength and corrosion resistance of the composite plastic board, unit block 21 can be detached from the pier more quickly, while ensuring the integrity of the pier surface.

[0036] Example 2: Please refer to Figure 5 Based on Embodiment 1, this utility model provides another technical solution: a sealing block 23 is provided on the upper part of unit block 21, and a sealing groove 24 is provided on the lower part of unit block 21, with the sealing block 23 abutting against the inside of the upper sealing groove 24.

[0037] When multiple unit blocks 1 and 21 are spliced ​​together to form a single layer of template, the upper and lower unit blocks 21 will not fit together perfectly when the multiple layers of template are spliced ​​together, which will cause leakage between the upper and lower unit blocks 21. In order to ensure the sealing between the upper and lower unit blocks 21, the sealing block 23 can provide space for the sealing groove 24 to abut. The sealing block 23 and the sealing groove 24 can cooperate to ensure the sealing between two adjacent unit blocks 21.
