Description

Technical Field

[0001] The utility model belongs to the technical field of railway construction, and in particular relates to an external formwork support device for cast-in-place beams with adjustable slope ratio for high-speed railways. Background Art

[0002] Adjustable slope cast-in-place beams are a bridge construction method in which the cross-section of the beam can be adjusted to adjust the slope according to design requirements. This method is often used to build bridges that require different cross-sectional shapes or slopes. In traditional bridge construction, once the cross-section and slope of the beam are determined, they cannot be changed. However, adjustable slope cast-in-place beam technology allows the slope of the beam to be adjusted as needed during construction to meet specific design requirements, which can bring many benefits, such as better structural performance, lower construction costs and shorter construction time. To achieve adjustable slope cast-in-place beams, special formwork and support structures are required to enable the shape and slope of the beam to be adjusted when pouring concrete. In addition, precise calculation and control of the construction process are required to ensure that the final structure meets the design requirements. In short, adjustable slope cast-in-place beams are an innovative bridge construction method that provides greater flexibility to adapt to different design requirements and construction conditions. This technology helps to improve bridge performance, reduce construction costs and shorten construction time.

[0003] With the rapid development of high-speed railway network, the construction of cast-in-place turnout beams has become an indispensable component. The different slope ratios of the single-track and double-track outer webs of cast-in-place turnout beams increase the one-time investment in the formwork support system. In order to achieve the universality of the single-track and double-track outer formwork support systems, it has become a difficult problem that needs to be overcome. Utility Model Content
