Leakage occurs at the connection of the plate 2. At the same time, this method is easy to disassemble, which is convenient for the later removal of the formwork 2; the connecting plates 3 on the two formworks 2 are fastened by multiple bidirectional screws 4 and outer screw fastening bolts 41, and a support member 5 is installed on the outer side of the connecting plate 3. The support member 5 is set to be inclined, and the other end of the support member 5 is fixed on the ground 1. By arranging an inclined support member 5 on the connecting plate 3 and fixing it to the ground, it can support the connecting plate 3 and the formwork 2 when pouring concrete, preventing the formwork 2 and the connecting plate 3 from being tilted due to the pressure of the concrete, thereby ensuring that the side of the cast concrete will not be deformed.

[0021] Reference Figure 3 In one embodiment, a plurality of first through holes 31 are formed on both sides of the connecting plate 3 , and a plurality of bidirectional screw rods 4 pass through the first through holes 31 on the two connecting plates 3 .

[0022] Specifically, there are three first through holes 31 , which are respectively arranged at the top and the side of the L-shaped connecting plate 3 , with one at the top and two at the side. The number and position of the bidirectional screw rods 4 are the same as those of the first through holes 31 .

[0023] In this embodiment, the setting of the first through hole 31 facilitates the insertion of the bidirectional screw rod 4. This method of using the bidirectional screw rod 4 for insertion and reinforcing it with the screw rod fastening bolt 41 enables the connecting plate 3 to drive the template 2 to be tightened, thereby preventing leakage of slurry. At the same time, this method is easy to disassemble, which is convenient for the later removal of the template 2.

[0028] Specifically, when pouring and setting up the formwork 2 on the uneven ground 1, thin steel bars can be used instead of the bolts 7 to fix one end of the support member 5.

[0029] In this embodiment, the two ends of the support member 5 are fixed to the ground 1 and the template 2 respectively by bolts 6 and studs 7 to play a supporting role. At the same time, this detachable fixing method also facilitates the later disassembly of the template 2 and the connecting plate 3, thereby improving the reuse rate of the template 2.

[0030] In this embodiment, an inclined support member 5 is provided on the connecting plate 3 and fixed to the ground, so that when pouring concrete, it can provide support for the connecting plate 3 and the formwork, preventing the formwork 2 and the connecting plate 3 from tilting due to the pressure of the concrete, thereby ensuring that the side surfaces of the cast concrete will not be deformed.
