[0047] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment provides a novel cantilever formwork 15 construction structure of a hollow thin-walled high pier 11, which is arranged on the high pier 11 and includes:

[0048] Triangular support frame 12, construction platform 13, back rib frame 14, template 15, adjustable diagonal brace 16;

[0049] The construction platform 13 is fastened to the high pier 11, and the construction platform 13 is arranged in a horizontal direction;

[0050] The bottom of the back rib frame 14 is rotatably arranged on the construction platform 13 through a support seat 300; the length direction of the adjustable diagonal brace 16 has a first end 16a and a second end 16b opposite to each other, the first end 16a is hinged to the back rib frame 14 through a first mounting seat 100, and the second end 16b is hinged to the construction platform 13 through a second mounting seat 200; the adjustable diagonal brace 16 can support the back rib frame 14 to move away from or close to the construction platform 13;

[0051] Along the extension direction of the construction platform 13, the support seat 300 is detachably arranged on the construction platform 13, so that the bottom of the back rib frame 14 can be close to or away from the high pier 11;

[0052] Along the extension direction of the construction platform 13, the second mounting seat 200 is detachably arranged on the construction platform 13, so that the second end 16b can be close to or away from the high pier 11; the first mounting seat 100 is detachably arranged on the back rib frame 14, so that the first end 16a can be adjusted in the height direction of the back rib frame 14;

[0053] The template 15 is detachably arranged on the back frame 14 ; the top of the triangular support frame 12 is arranged at the bottom of the construction platform 13 , and the bottom of the triangular support frame 12 is arranged at one end of the high pier 11 away from the construction platform 13 .

[0054] The first end 16a of the adjustable diagonal brace 16 is detachably mounted on the back rib frame 14 through the first mounting seat 100, so that the first end 16a can be adjusted along the height direction of the back rib frame 14; the second end 16b is detachably mounted on the construction platform 13 through the second mounting seat 200, so that the second end 16b can be close to or away from the high pier 11; along the extension direction of the construction platform 13, the support seat 300 is detachably mounted on the construction platform 13, so that the bottom of the back rib frame 14 can be close to or away from the high pier 11. In this way, the back rib frame 14 can be fixed at a preset position on the construction platform 13, and the first end 16a and the second end 16b of the adjustable diagonal brace 16 can conveniently be set to adjust the inclination angle of the back rib frame 14 at a larger angle, thereby increasing the flexibility of the back rib frame 14 on the construction platform 13 and the flexibility of the back rib frame 14 inclination adjustment. In summary, the new cantilever formwork 15 construction structure of the hollow thin-walled high pier 11 has the advantages of simple structure, convenient installation, and space saving, which is conducive to improving construction efficiency.

[0055] Further, the adjustable diagonal brace 16 itself is a prior art, and its principle is to make the back rib frame 14 close to or away from the construction platform 13 by its own extension or shortening. Specifically, because the bottom of the back rib frame 14 is hinged on the construction platform 13, when the first end 16a of the adjustable diagonal brace 16 drives the top of the back rib frame 14 to be close to or away from the construction platform 13, the back rib frame 14 can rotate relative to the support seat 300. At the same time, because the back rib frame 14 is connected to the construction platform 13 through the support seat 300, the back rib frame 14 is connected to the first end 16a through the first mounting seat 100, and the construction platform 13 is connected to the second end 16b through the second mounting seat 200, and the support seat 300, the first mounting seat 100, and the second mounting seat 200 can all flexibly adjust the position, so that the template 15 on the back rib frame 14 can flexibly adjust the distance and angle between it and the high pier 11, thereby improving the flexibility of the cantilever template 15 construction and improving the construction efficiency.

[0056] from Figure 1 , Figure 2 and Figure 4It can be seen that the construction platform 13 is provided with a plurality of mating through holes 400; and the plurality of mating through holes 400 are evenly distributed on the surface of the construction platform 13.

Here, the position of the support seat 300 on the construction platform 13 can be flexibly adjusted by the support limiter columns 310.

[0058] Optionally, the support limit column 310 is a limit pin. The pin-hole combination has the advantages of simple structure, low cost, good versatility, and easy disassembly.

[0060] Optionally, the second mounting column 220 is a limit pin. The pin-hole combination has the advantages of simple structure, low cost, good versatility, and easy disassembly.

[0061] Further, in this embodiment, the matching through hole 400 includes a step portion 401 and a straight hole 402 connected in sequence; the step portion 401 is close to the top surface of the construction platform 13. The step portion 401 can be combined as a guide portion for supporting the limit column 310 and the second installation column 220, thereby facilitating the installation of the support seat 300 and the second installation seat 200.

Such a setting method can ensure the smooth loading and unloading operation of the first mounting seat 100.

[0063] Optionally, the first mounting post 110 is threadedly connected to the adjustment through hole 500. The threaded connection has good fastening and a certain self-locking effect, and can prevent the first mounting seat 100 from being separated from the back rib frame 14.

[0064] Optionally, a plurality of adjustment holes 500 are provided on one side of the back rib frame 14 away from the adjustable diagonal brace rod 16, and the adjustment holes 500 can be used to detachably cooperate with the template 15. That is, the two sides of the back rib frame 14 are provided with symmetrically arranged adjustment holes 500, and the adjustment holes 500 can be used as a portion connected to the template 15 and as a connection portion with the first mounting seat 100, thereby improving the versatility of the back rib frame 14.
