The diameter of the inner support steel pipe 3 is 48mm, and a portal steel frame 4 is arranged on the outer side of the two component formworks 1. A tension screw 6 is arranged on the portal steel frame 4, and threaded rods 8 are symmetrically arranged on the inner side of the portal steel frame 4. The threaded rods 8 are fixedly connected to the inner side of the portal steel frame 4, the inner support pads 2 are welded to the reinforcement component, and a support assembly is arranged on the outer side of the threaded rod 8.

[0033] See also Figure 2 Two through holes 5 are symmetrically provided on the portal steel frame 4, and tension screws 6 are arranged inside the two through holes 5. The diameter of the through holes 5 is adapted to the diameter of the tension screws 6. Two nuts 7 threadedly sleeved on the outside of the tension screws 6 are symmetrically provided on the outside of the portal steel frame 4. The nuts 7 on the outside of the tension screws 6 are tightened to firmly fix the tension screws 6 on the portal steel frame 4, thereby strengthening the rigidity of the portal steel frame 4. Two gaskets are symmetrically sleeved on the outside of the tension screws 6. The gaskets increase the contact area between the nuts 7 and the surface of the portal steel frame 4, reduce pressure, prevent loosening, and protect the surface of the portal steel frame 4 from being scratched. The gaskets are arranged between the nuts 7 and the portal steel frame 4.

[0034] See also Figure 3 The support assembly includes a nut 9 threadedly sleeved on the outer side of the threaded rod 8, a connecting rod 11 is fixedly connected to the outer side of the nut 9, and an abutment block 10 is fixedly connected to the end of the connecting rod 11 away from the nut 9. The nut 9 on the outer side of the threaded rod 8 is screwed to make the nut 9 approach the component template 1, thereby driving the connecting rod 11 and the abutment block 10 to approach the component template 1 until the abutment block 10 abuts against the surface of the component template 1, and the screwing of the nut 9 is stopped, thereby supporting the outer side of the component template 1, and the nut 9 and the abutment block 1 0, and the four connecting rods 11 are arranged in a circular array. This design improves the stability of the connection between the nut 29 and the abutment block 10, and indirectly improves the stability of the supporting member template 1. The outer side of one end of the threaded rod 8 away from the portal steel frame 4 is fixedly connected with a limiting ring. The diameter of the limiting ring is larger than the diameter of the threaded rod 8. The limiting ring plays a role of blocking and limiting the nut 29 to prevent the nut 29 from falling from the outer side of the threaded rod 8. The limiting ring is arranged between the nut 29 and the abutment block 10.

[0035] The implementation principle of this embodiment is as follows: after the component reinforcement is tied, a cylindrical inner support pad 2 with short reinforcement is welded at the bottom of the component reinforcement to position the inner side of the bottom of the component template 1, and then the two component templates 1 are temporarily hoisted to the installation position, and the inner bottom of the component template 1 is made close to the outer side of the inner support pad 2, and the top is temporarily fixed with iron wire and the component reinforcement, and the pre-processed door-shaped steel frame 4 is erected on both sides of the component template 1, and the inner support steel pipe 3 is placed on the upper side between the two component templates 1, and the iron wire is released. Temporary fixation, then screw the nut 2 9 on the outside of the threaded rod 8, so that the nut 2 9 approaches the component template 1, thereby driving the connecting rod 11 and the abutment block 10 to approach the component template 1, until the abutment block 10 abuts on the surface of the component template 1, stop screwing the nut 2 9, so as to support the outside of the component template 1, and then pass the tension screw 6 through the through hole 5, and tighten the nut 1 7 on the outside of the tension screw 6, so as to firmly fix the tension screw 6 on the portal steel frame 4, so as to strengthen the portal steel frame 4.
