Description

Technical Field

[0001] The invention relates to a construction method, in particular to a construction method for a rotatable post-casting strip support, and belongs to the technical field of building construction. Background Art

[0002] Post-cast strips are a common construction method in construction projects. They are mainly used to deal with temperature stress and uneven settlement problems in concrete structures. They form a strong connection through later pouring. However, in traditional post-cast strip construction, disposable wooden formwork or simple steel formwork is generally used for support. This method has the following technical defects: Serious waste of materials: Disposable wooden and steel formworks usually cannot be reused after use and are easily damaged during dismantling, resulting in a large amount of construction waste and increasing construction costs.

[0003] Low construction efficiency: The traditional support system requires manual adjustment and assembly on site, which is complicated and time-consuming, and can easily delay the construction progress.

[0004] Quality is difficult to guarantee: Due to insufficient rigidity of the support system or low installation precision, the formwork is prone to deformation, resulting in quality problems such as loose joints or leakage of concrete after construction of the post-cast zone.

[0005] The environmental impact is large: the use of disposable formwork not only consumes a large amount of wood or steel, but also generates a large amount of garbage, causing environmental pollution.

[0006] In response to the above problems, the industry has gradually explored the use of turnaround formwork and support systems to optimize the post-casting construction process, but the existing technology still has the following shortcomings: the turnaround support system has a complex structure and heavy weight, and on-site installation still requires a lot of manpower and time; some designs lack modular concepts, and the support system has low applicability and cannot meet the needs of different project scales; the support system is susceptible to wear and tear during repeated use, the number of turnovers is limited, and the service life is short.

[0007] Based on the above problems, the present invention provides a construction method for a recyclable post-cast strip support. Through modular design and optimized construction process, efficient installation and reuse of the support system can be achieved, which not only reduces construction costs and shortens construction period, but also improves the construction quality of the post-cast strip, and has significant economic and environmental benefits. Summary of the invention

[0014] As a preferred technical solution of the present invention, support feet with adjustable heights are installed at the bottom of the support frame, and the height is adjusted to adapt to uneven terrain to ensure the horizontality of the support system.

[0015] As a preferred technical solution of the present invention, after the support frame is dismantled, the surface of the components is subjected to anti-corrosion treatment, concrete residues are removed, and a protective coating is applied to extend the turnover times and service life of the support system.
