[0019] Embodiment:

[0020] As Figure 1 shown in Figure 2 figures, a reinforced formwork for building construction projects includes a first formwork 1 and a second formwork 2. A sealing mechanism is provided inside the second formwork 2. The sealing mechanism includes: a C-shaped sealing piece 6 for sealing the joint between the first formwork 1 and the second formwork 2. A support mechanism is provided inside the second formwork 2. The support mechanism includes an airbag 8 for squeezing and supporting the C-shaped sealing piece 6; an arc-shaped groove 3 is opened at the bottom end of the first formwork 1, and an inner groove 4 is opened on one side surface of the second formwork 2. One side of the C-shaped sealing piece 6 is inside the inner groove 4. A slot 5 is opened on the inner wall of the inner groove 4. One side of the C-shaped sealing piece 6 is fixedly connected with an insert plate 7, and one end of the insert plate 7 is inside the slot 5; the bottom surface of the airbag 8 is fixedly connected with the inner wall of the inner groove 4. One side of the airbag 8 is fixedly connected with an air cylinder 9. The air cylinder 9 is communicated with the inside of the airbag 8. A piston rod 10 is provided inside the air cylinder 9. One end of the piston rod 10 penetrates through the air cylinder 9 and is outside the second formwork 2; a cross groove 13 is opened at the bottom end of the piston rod 10. A nut 12 is movably connected inside the cross groove 13. A reinforcing screw 11 is threadedly connected inside the nut 12. A second thread groove 15 is opened on one side surface of the first formwork 1, and a first thread groove 14 is opened on one side surface of the second formwork 2. One end of the reinforcing screw 11 penetrates through the first thread groove 14 and is inside the second thread groove 15;

[0021] The formwork for pouring existing buildings is prone to deformation due to long-term repeated disassembly and installation, wear and extrusion, etc. Leakage of slurry is likely to occur at the joints, affecting the use of pouring. By setting a sealing mechanism, during installation, first insert the insertion plates 7 at both ends of the C-shaped sealing piece 6 into the inner side of the slot 5 respectively, and then bite and join the first formwork 1 and the second formwork 2 with each other. Rotate the reinforcing screw 11. Under the interaction of the threads, one end of the reinforcing screw 11 enters the inner side of the second thread groove 15 from the first thread groove 14. Since the nut 12 is threadedly connected to the reinforcing screw 11, the nut 12 can rotate and move inside the cross groove 13. The reinforcing screw 11 drives the nut 12 to rotate at the same speed. The nut 12 pushes the piston rod 10 to penetrate deep into the inner side of the air cylinder 9. The air inside the air cylinder 9 is squeezed by the piston rod 10 and enters the inner side of the airbag 8. After the airbag 8 is filled with air, it fits tightly with the C-shaped sealing piece 6, supporting and pushing the C-shaped sealing piece 6 to fit tightly with the inner wall of the inner groove 4 and the arc groove 3. When one end of the reinforcing screw 11 completely enters the inner side of the second thread groove 15, rotate the nut 12. The nut 12 pushes the piston rod 10 on the outer side of the second formwork 2 to fit tightly with the second formwork 2 for final tightening and fixing to complete the installation; by setting a sealing structure, the joint between the first formwork 1 and the second formwork 2 is sealed to prevent slurry leakage. By setting a support structure, the C-shaped sealing piece 6 can be released and pressured, avoiding the single C-shaped sealing piece 6 being affected by long-term extrusion and aging, losing elasticity and losing the sealing performance. The C-shaped sealing piece 6 is small in size and simple to replace, improving work efficiency and reducing costs.

[0022] In other embodiments, this embodiment discloses, please refer to Figure 1 and Figure 3 As shown, a first alignment block 16 is fixedly connected to the bottom end of the first formwork 1. A slot 21 is opened on one surface of the first alignment block 16. A second alignment block 17 is fixedly connected to the bottom end of the second formwork 2. A chute 20 is opened on one surface of the second alignment block 17. A limiting groove 22 is opened on the inner wall of the chute 20. An L-shaped push rod 18 is arranged inside the chute 20. One end of the L-shaped push rod 18 penetrates through the chute 20 and enters the slot 21; the other end of the L-shaped push rod 18 is fixedly connected to a spring 19. One end of the spring 19 is fixedly connected to the inner wall of the chute 20;

[0023] Before the first template 1 and the second template 2 are fixed, it is necessary to push the L-shaped push rod 18 to rotate 90 degrees inside the chute 20. After that, the protruding handle part of the L-shaped push rod 18 leaves the limit groove 22. The L-shaped push rod 18 is no longer restricted by the limit groove 22, and the spring 19 in the compressed state pushes the L-shaped push rod 18 into the inner side of the card slot 21 of the first alignment block 16; by setting the L-shaped push rod 18, when the restriction of the L-shaped push rod 18 is released, the L-shaped push rod 18 smoothly enters the inner side of the card slot 21 from the chute 20, indicating that the first template 1 and the second template 2 are aligned, and the first template 1 and the second template 2 can be fixed. Moreover, when the reinforcing screw 11 is rotated, it can also smoothly enter the inner side of the second thread groove 15. If it cannot enter the inner side of the card slot 21, it is necessary to adjust the positions of the first template 1 and the second template 2 to ensure that each screw for reinforcement can smoothly enter the thread groove, and to avoid deformation and damage of the thread groove and the screw during rotation.

[0024] The above has described in detail the embodiments of the present invention in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the gist of the present invention.
