Technical Field

[0001] The present application relates to the technical field of shallow silo construction, and in particular to a steel bar positioning system for shallow silo slipform construction. Background Art

[0002] Shallow silos are also called short silos. The main body of the silo wall is mostly reinforced concrete structure. At present, the construction of reinforced concrete silo walls has generally adopted the slipform technology. The slipform construction technology is a construction technology with high mechanization degree, fast construction speed, mature technology, strong structural integrity, good seismic performance, guaranteed safe operation and significant economic comprehensive benefits in the construction of main structure engineering in China.

[0003] During slipform construction, it is necessary to complete the positioning and binding of steel bars within a specified unit time. During the construction process, it is necessary to prevent the spacing of self-weight horizontal steel bars from being too large and shifting, and to ensure the construction quality of slipform concrete, which makes slipform construction difficult. The existing technology often uses ladder bars (transverse steel bar positioning frames) or vertical steel bar positioning frames to position the steel bars. However, the ladder bars are prone to rotation or shifting during use due to their high height and poor structural stability, which in turn affects the positioning effect of the transverse steel bars.

[0004] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content

[0047] The connection frame 3 is arranged on the first annular reinforcement 1 and the second annular reinforcement 2 at the same time, and is used to limit the transverse reinforcement positioning frame;

[0048] A plurality of vertical steel bar positioning members 10 are provided at intervals in the circumferential direction on one side opposite to the first annular rib 1 and the second annular rib 2;

[0049] The transverse reinforcement positioning frame includes a plurality of transverse reinforcement positioning members 7 and first vertical reinforcements 5 and second vertical reinforcements 6 arranged in parallel inside and outside. The plurality of transverse reinforcement positioning members 7 are arranged at intervals along the axial direction of the first vertical reinforcements 5 and the second vertical reinforcements 6.
