[0002] At present, when constructing complex curved structures, under the existing wooden formwork erection technology, the flexibility and plasticity of wooden formwork are relatively low, making it difficult to accurately replicate complex or high-precision curved structures, which may cause deviations between the finished product and the design drawings. The production of curved wooden formwork also requires very high craftsmanship of construction workers, and more time is required to cut, trim and splice to meet specific curvature requirements, which greatly increases labor costs and construction cycles. In addition, wooden formwork is sensitive to changes in humidity and temperature, and is prone to moisture expansion or drying shrinkage and change size, affecting the accuracy and stability of the curved structure. In terms of green construction and environmental protection, wooden formwork is prone to lose its original shape and stability due to deformation, wear or moisture after one or several uses, which limits its application in projects that require repeated use and increases material and labor costs.
[0003] For this reason, we have developed a special-shaped lace arc steel formwork structure to solve the above problems. Utility Model Content
