A U-shaped plate 1 is connected to the top of the sliding plate 2. A pair of first through holes 12 are opened inside the U-shaped plate 1, and a positioning mechanism is provided inside the first through holes 12. The sliding plate 2 is fixedly connected to the top plate 6 through the positioning mechanism.
[0023] The bottom of the slider 18 is connected to a side plate support frame 8, the back of the side plate support frame 8 is connected to a pair of first diagonal braces 10, and the back of the pair of first diagonal braces 10 is connected to scissor braces 16.
[0024] like Figure 1 and Figure 2 As shown, the positioning mechanism includes a U-shaped insert 11, which passes through the interior of the first through hole 12. Both ends of the U-shaped insert 11 are fixedly connected to a fixing ring 14 inside the U-shaped plate 1. Both ends of the U-shaped insert 11 are fitted with a return spring 13 near the top of the fixing ring 14. One end of the return spring 13 is fixedly connected to the U-shaped plate 1, and the other end of the return spring 13 is fixedly connected to the fixing ring 14. When the template needs to be removed, the U-shaped insert 11 on both sides can be pulled upward to remove it from the slot 4 at the top of the top plate 6, thereby moving the side plate support frame 8 on both sides and making it easy to remove the fair-faced concrete template on both sides.
[0025] like Figure 1 and Figure 2 As shown, the sliding plate 2 has a pair of second through holes 17 inside, the position of the second through holes 17 corresponds to the position of the first through hole 12, and both ends of the U-shaped insert 11 pass through the interior of the pair of second through holes 17 and extend into the interior of the slot 4.

[0027] like Figure 1 and Figure 2 As shown, guide rod 3 is set in a U-shape.
[0028] like Figure 3As shown, the shorter arms of the side plate support frame 8 are respectively connected to the second diagonal brace 15 and the third diagonal brace 19.

Similarly, when it is necessary to remove the formwork, the U-shaped inserts 11 can be removed from the slots 4 at the top of the top plate 6, and the side plate support frames 8 on both sides can be moved to facilitate the removal of both sides of the fair-faced concrete formwork. The disassembly and assembly steps are simple.
