[0022] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0023] See Figure 1-5 In one embodiment of this utility model, an integrated steel formwork structure for retaining walls includes: a formwork 1, an upper construction platform, and a lower construction platform. The upper and lower construction platforms are both installed at the rear end of the formwork 1 and are distributed in an upward and downward direction. Construction personnel can conveniently carry out construction, management, and quality inspection of the retaining wall with the help of the upper and lower construction platforms.

[0024] Specifically, the template 1 consists of a template frame and a whole steel panel 11. The panel 11 is fixed to the front end of the template frame by welding. With the support of the template frame, the bending strength and deflection of the panel 11 can be greatly improved. The template frame acts as the skeleton of the entire template structure. For this purpose, the template frame is composed of multiple horizontal ribs 12 and multiple vertical ribs 13 arranged in a longitudinal and transverse manner.

[0025] For ease of installation, the top of template 1 is also equipped with multiple lifting lugs.

[0026] In one embodiment, panel 11 has dimensions of 5000×1800mm and a thickness of 6mm; horizontal ribs 12 are made of 10# channel steel, with a spacing of 300mm between them; vertical ribs 13 are made of double-layered 16# channel steel, with a spacing of 850mm between them; each vertical rib 13 has two tie holes spaced 1750mm apart. In practice, two connecting plates 14 are installed on the vertical ribs 13 at vertical positions, each connecting plate 14 having one tie hole. The tie holes are mainly used to anchor the reinforcing bars to the vertical ribs 13, thereby fixing the entire formwork structure in the construction position.

[0027] The following construction platform is used as an example for illustration.

[0028] The lower construction platform includes a walkway 4 and multiple lower support frames 3. The multiple lower support frames 3 are all fixed at the rear end of the formwork frame, and are arranged at intervals along the length of the panel 11 at the same horizontal height. The distance between two adjacent lower support frames 3 is 1700mm. The walkway 4 is laid on the multiple lower support frames 3. The walkway 4 can always maintain a horizontal and stable posture through the lower support frames 3, so as to facilitate the walking of construction personnel.

[0029] The lower support frame 3 includes a connecting angle steel 31, a support pipe 32, a guardrail pipe 33, an adjustable tie rod 34, several connectors 35, several pins 36, and several connecting ears 38. The connecting angle steel 31, the support pipe 32, and the adjustable tie rod 34 form a triangular frame structure. In implementation, the first end of the support pipe 32 is rotatably connected to the middle of the connecting angle steel 31, one end of the adjustable tie rod 34 is rotatably connected to the lower end of the support pipe 32, and the other end of the adjustable tie rod 34 is rotatably connected to the lower end of the connecting angle steel 31. In implementation, these rotatable connections are all achieved by the cooperation of the connectors 35 and the pins 36. The upper end of steel 31 is fixedly connected to template 1; walkway 4 is set on support pipe 32; the adjustable tie rod 34 here has the advantages of freely adjustable length, high stability, simple structure and space saving. Accordingly, changing the length of the adjustable tie rod 34 can adjust the angle between support pipe 32 and connecting angle steel 31. For example, when constructing a retaining wall on a mountain with a large slope, the length of the adjustable tie rod 34 can be adjusted to keep support pipe 32 horizontal, so that walkway 4 can be in a stable state and ensure construction safety; the guardrail pipe 33 is fixedly set at the tail end of support pipe 32, and the connecting ear 38 is fixed on guardrail pipe 33.

[0030] The upper construction platform is similar in structure to the lower construction platform. The difference is that, in order to create a certain height difference between the upper and lower construction platforms, the upper construction platform includes an upper support frame 2. The connecting angle steel in the upper support frame 2 that is used to connect with the transverse rib is shorter than the connecting angle steel in the lower support frame 3.

[0031] In one embodiment, in order to improve the overall load-bearing capacity of the lower support frame 3, each connecting angle steel 31 is also equipped with a reinforcing angle steel 37 at its upper end.

[0032] In one embodiment, a guardrail is provided between two adjacent lower support frames 3. The guardrail is composed of angle steel and wire mesh. The guardrail is fixed to the guardrail tube 33 by bolts through connecting ears 38.

[0033] To ensure construction safety, the walkway slab needs to possess strong bending strength and deflection resistance. The walkway slab 4 includes a steel frame 41 and a patterned steel plate 42; the steel frame 41 is made of 8# channel steel; the patterned steel plate 42 is laid on the steel frame 41; in addition, multiple reinforcing steel plates 43 are welded to the inner side of the steel frame 41, and the reinforcing steel plates 43 abut against or are welded to the lower end face of the patterned steel plate 42 for fixation.

[0034] This technical solution, by setting up an adjustable horizontal construction platform on the back of the template, facilitates the construction and quality management of the retaining wall, while ensuring the safety of construction personnel.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
