B. inserting steel bars into the prefabricated holes according to design requirements, and filling and plugging unused prefabricated holes;

C. binding and reinforcing the steel bars;

D. and pouring concrete into the inner side formwork and the outer side formwork, and removing the inner side formwork and the outer side formwork after the concrete is cured.

Preferably, the top and the bottom of the lateral side of the outer formwork are respectively provided with a rib plate.

Preferably, in the step C, when the reinforcing steel bars are bound and reinforced, the target reinforcing steel bars are wound by using steel wires to stress the target reinforcing steel bars, then the support rings are inserted into the corresponding prefabricated holes in which the target reinforcing steel bars are inserted, and finally the target reinforcing steel bars are bound and reinforced by using the steel wires.

Preferably, the support ring includes the ring body, and the ring body outside is provided with the rubber layer with prefabricated downthehole wall interference fit, and the inboard activity of ring body is pegged graft and is had the spacing post of a plurality of, and threaded connection has the adjusting bolt with spacing post one-to-one on the ring body, and the medial extremity of spacing post is provided with the inclined plane portion, adjusting bolt and inclined plane portion crimping, and the outside end of spacing post is provided with recessed arc portion, arc portion and reinforcing bar crimping.

A thin-wall platform is manufactured by the construction method of the thin-wall platform.

Adopt the beneficial effect that above-mentioned technical scheme brought to lie in: according to the invention, the accuracy of positioning the reinforcing steel bars can be effectively improved by improving the structure of the thin-wall platform formwork and optimizing the pouring process of the thin-wall platform, and the formwork can be fixed more firmly by using the specially designed support ring, so that the deformation of the formwork is further avoided.

Drawings

FIG. 1 is a block diagram of a thin-walled stage in accordance with an embodiment of the present invention.

FIG. 2 is an axial cross-sectional view of a support ring in one embodiment of the present invention.

In the figure: 1. a foundation; 2. an inner side template; 3. an outer side template; 4. prefabricating holes; 5. an arc-shaped portion; 6. reinforcing steel bars; 7. a rib plate; 8. a support ring; 9. a steel wire; 10. a ring body; 11. a rubber layer; 12. a limiting column; 13. adjusting the bolt; 14. a bevel portion.

Detailed Description

The standard parts used in the invention can be purchased from the market, the special-shaped parts can be customized according to the description and the description of the attached drawings, and the specific connection mode of each part adopts the conventional means of mature bolts, rivets, welding, sticking and the like in the prior art, and the detailed description is not repeated.

Referring to fig. 1-2, one embodiment of the present invention includes the steps of:

A. an inner side template 2 and an outer side template 3 are respectively and fixedly installed on the foundation 1, and the inner side template 2 is positioned on the inner side of the outer side template 3; a plurality of prefabricated holes 4 which are in one-to-one correspondence are arranged on the inner side template 2 and the outer side template 3;
