Description

Technical Field

[0001] The support mold of the utility model belongs to the technical field, and particularly relates to an adjustable support mold for an arched beam. Background Art

[0002] For the formwork support system of cast-in-situ concrete arched members, wooden formwork is usually sawn into small strips, and then processed into arc-shaped formwork and arc-shaped skeletons that fit the members according to the structural shape for reinforcement. The deficiencies of the formwork support system for cast-in-situ concrete arched members are mainly reflected in the following aspects: Material waste: In the traditional method, wooden formwork is usually sawn into small strips, and then processed into arc-shaped formwork and arc-shaped skeletons for reinforcement according to the structural shape. This approach is not only time-consuming and laborious, but also prone to material waste due to the need for a large amount of customization and cutting. Low construction efficiency: Since the formwork and the support system need to be adjusted, disassembled and assembled multiple times, and each piece of formwork needs to be processed and fixed individually, this greatly increases the construction time and labor intensity, and reduces the overall construction efficiency. Stability problems: When the traditional formwork support system bears the heavy pressure during the concrete pouring process, its stability is often difficult to guarantee. Especially in the construction of large-span or irregularly shaped arched structures, the risk of instability of the support system is relatively high. Difficult appearance quality control: The arc-shaped formwork and its support system have a great influence on the appearance and forming effect of the concrete wall. Before actual construction, it is necessary to check the formwork and the processed steel pipes again, and make appropriate adjustment treatments to ensure that the radian and curvature of the steel pipes match the arc wall, otherwise quality defects are very likely to occur. Safety risks: Since the formwork support system needs to bear a large load, if it is not designed and installed properly, it is easy to cause a collapse accident. Content of the Utility Model
