Detailed Implementation

[0036] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0037] Example 1: A reinforced concrete box girder structure for continuous casting, comprising: a bottom support plate 1, an inner wall formwork 2, an outer wall formwork 6, a bottom plate formwork, and a supporting structure;

[0038] The base plate 1 is placed on the pouring site;

[0039] The inner wall template 2 and the outer wall template 6 are both erected perpendicular to the bottom support plate 1. The outer wall template 6 is arranged parallel to the outside of the inner wall template 2, and the distance between the outer wall template 6 and the inner wall template 2 is the thickness of the concrete box structure wall panel.

[0040] The base plate template includes an inner support plate 91, an outer support plate 92, and a surrounding plate 93. The inner support plate 91 is placed on top of the inner wall template 2 and its outer edge is flush with the outer edge of the inner wall template 2. The outer support plate 92 is horizontally attached to the outer edge of the outer wall template 6. The upper surfaces of the inner support plate 91, the outer wall template 6, and the outer support plate 92 are at the same horizontal height. The surrounding plate 93 is placed on the outer support plate 92 and their outer surfaces are flush.

[0041] The supporting structure supports and fixes the supporting base plate 1, inner wall template 2, outer wall template 6, and base plate template.

[0042] The inner wall template 2, the outer wall template 6, the inner support plate 91, and the surrounding plate 93 are respectively divided into the left inner wall template, the left outer wall template, the left inner support plate, and the left surrounding plate; the right inner wall template, the right outer wall template, the right inner support plate, and the right surrounding plate; the front inner wall template, the front outer wall template, the front inner support plate, and the front surrounding plate; and the rear inner wall template, the rear outer wall template, the rear inner support plate, and the rear surrounding plate. The corresponding parts together form the inner wall template box and the outer wall template box.

[0043] The support and fixing structure includes an inner hoop plate 3, an inner horizontal brace 4, and an inner diagonal brace 5. The inner hoop plate 3 is horizontally and tightly attached to the inner side of the inner wall formwork 2. The inner horizontal brace 4 is vertically placed between the inner hoop plates 3 on two opposite inner wall formwork 2. The inner diagonal brace 5 is inclined and supported between the inner hoop plate 3 and the ground. These three internal support and fixing structures limit the displacement of the inner wall formwork and prevent the concrete side panels from tilting and expanding inward during pouring and curing.

[0044] The support and fixing system includes an outer hoop plate 7 and an outer diagonal brace 8. The outer hoop plate 7 is horizontally and tightly attached to the outside of the outer wall formwork 6, while the outer diagonal brace 8 is inclined and supported between the outer hoop plate 7 and the ground. These two external support and fixing structures limit the displacement of the outer wall formwork, preventing the concrete side slab from tilting and expanding outwards during pouring and curing. The support and fixing system also includes a vertical support 10, which is vertically supported between the outer support plate 92 and the ground. This vertical support fixing structure provides support for the outer support plate, preventing the concrete base slab from being damaged by gravity during pouring and curing.

[0045] The inner wall formwork 2 is used to tie the side plate reinforcement of the box structure to the outside. The concrete cover thickness, reinforcement size, and reinforcement spacing in the structural design are converted into the relative distance between the reinforcement and the inner wall formwork, so as to accurately position and arrange the side plate reinforcement.

[0046] The inner support plate 91 and outer support plate 92, and the inner part of the surrounding plate 93, are used to tie the bottom plate reinforcement of the box structure. The concrete cover thickness, reinforcement size, and reinforcement spacing in the structural design are converted into the relative distance between the reinforcement and the support plate or surrounding plate, so as to accurately position and arrange the bottom plate reinforcement.

[0047] Example 2, as Figures 1-4 As shown, a method for continuous casting of reinforced concrete box girder structures comprises the following steps:

[0048] 1) Determine the structural dimensions, reinforcement configuration, and concrete mix proportions according to the design specifications;

[0049] 2) Select a flat ground as the pouring site and place the bottom support plate 1 on the pouring site;

[0050] 3) The inner wall template 2 is erected perpendicular to the bottom support plate 1, the inner hoop plate 3 is horizontally and tightly attached to the inner side of the inner wall template 2, the inner horizontal brace 4 is horizontally placed between the inner hoop plates 3, and the inner diagonal brace 5 is placed between the inner hoop plate 3 and the ground.

[0051] 4) Tie the side plate reinforcement of the box structure to the outside of the inner wall formwork 2;

[0052] 5) Erect the outer wall formwork 6 perpendicular to the bottom support plate 1, with the distance between it and the inner wall formwork 2 being the thickness of the concrete box structure wall panel. The outer hoop 7 is horizontally and tightly attached to the outside of the outer wall formwork 6, and the outer diagonal brace 8 is placed between the outer hoop 7 and the ground.

[0053] 6) The base plate template consists of an inner support plate 91, an outer support plate 92, and a surrounding plate 93. The inner support plate 91 is placed on top of the inner wall template 2 and its outer edge is flush with the outer edge of the inner wall template 2. The outer support plate 92 is horizontally attached to the outer edge of the outer wall template 6. The vertical support 10 is placed between the outer support plate 92 and the ground. The upper surfaces of the inner support plate 91, the outer wall template 6, and the outer support plate 92 are at the same horizontal height. The surrounding plate 93 is placed on the outer support plate 92 and the outer surfaces of the two are flush.

[0054] 7) Tie the bottom plate reinforcement of the box structure to the upper part of the inner support plate 91 and the outer support plate 92 and inside the surrounding plate 93;

[0055] 8) Pour concrete above the structural formwork, and continuously cast the box structure in the order of side plates first and bottom plates last.
