[0041] The back rib 5 is connected to the notch of the first reinforcing plate 13 , and an adjusting screw is also provided on one side of the second reinforcing plate 14 .

[0042] In the preferred embodiment, a cross link 17 is provided below the load-bearing bracket 15, and the cross link 17 is arranged between the lower diagonal braces. A step plate 16 is provided above the cross link 17, and the step plate 16 is used for construction workers to stand.

[0043] In the preferred embodiment, a support seat 10 is further provided on one side of the back rib 5, the support seat 10 is located below the pad 9, an upper support 11 is provided on one side of the support seat 10, and an upper step plate 12 is provided above the upper support 11, and the upper step plate 12 is used for construction workers to stand;

[0044] The upper bracket 11 is connected to the bracket seat 10 by bolts.

[0045] In the preferred embodiment, the anti-floating plate 20 is convex, with mounting holes symmetrically arranged on the bottom plate, and a raised top platform 22 arranged between the mounting holes. The anti-floating plate 20 is used to prevent the load-bearing bracket 15 from floating up and being unhooked.

[0046] In the preferred embodiment, the trapezoidal block 19 is in a right-angled trapezoid shape, an inclined table surface 24 is provided on one side below the trapezoidal block 19 , and a mounting hole 23 is provided above the trapezoidal block 19 , and the mounting hole 23 is used to connect to the bottom frame 3 .

[0047] A detailed description of a steel formwork capable of controlling the thickness of a protective layer is as follows: a detachable trapezoidal block 19 is provided at the top of the steel formwork during the construction of the backward cantilever flip formwork, which can effectively control the protective layer of the steel bars and can also play the role of a construction seam beautification seam of the upper and lower concrete layers. The connection between the inclined table 24 below the trapezoidal block 19 and the bottom frame 3 is an extended screw connection, that is, the beveled edge is extended on the plane by about 2 cm after intersecting the plane of the formwork. On the one hand, it is convenient to connect the convex structure with the plane of the steel plate, and on the other hand, it is used to artificially set a construction seam beautification seam plate 18, determine the thickness of the protective layer that needs to be controlled in advance, and convert it into the thickness outside the vertical main reinforcement edge, which is the length of the protruding right-angle side of the trapezoidal block 19;

[0048] During construction, the vertical main reinforcement is directly connected tightly with the right-angled trapezoidal block 18. Due to the tight connection, on the one hand, the pad setting of the top opening is omitted, and there is no need to verify the protective layer of each main reinforcement one by one, which greatly simplifies the construction. On the other hand, the main reinforcement and the steel formwork can be fixed to each other at the end by iron wire, etc., to form an overall rigid structure, which can effectively avoid the problem of steel bar or pad offset during concrete pouring. After the previous layer is poured, the top opening will naturally form an inward gap due to the protruding structure. At the same time, when the mold is turned over and poured next time, the concrete will naturally fill the gap, and the final overall construction joint position will be at the extended steel plate position of the right-angled trapezoid hypotenuse and the steel plate plane, that is, a neat beauty seam of the thickness of the steel plate is formed;

[0049] Backward cantilever formwork construction: The gate wall is constructed in layers. Since the back of the gate wall is gradually inclined toward the front, the inclined formwork will be subject to buoyancy during concrete pouring construction. However, there is no special anti-floating setting in the back-tilt cantilever formwork construction, so an optimized setting was made;

[0050] Specifically, two holes are symmetrically opened on the load-bearing bracket 15 corresponding to the anti-floating plate, and then the anti-floating plate 20 and the load-bearing bracket 15 are connected by bolts, so that the clamping groove 21 at the embedded anchor cone bolt of the previous backward cantilever mold structure becomes closed, and the embedded anchor cone bolt and the anti-floating plate 20 bear the buoyancy force as a whole.

[0051] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
