Description

Technical Field

[0001] This utility model relates to the field of steel formwork technology, specifically a rapid assembly and combination structure for railway bridge steel formwork. Background Technology

[0002] In modern construction, steel formwork is widely used as an important tool for concrete forming. It is not only reusable but also possesses excellent stability and durability, ensuring the high-quality completion of concrete structures. Compared to traditional materials such as wooden and plywood formwork, steel formwork is more resistant to harsh environments, reducing engineering quality problems caused by material deformation or damage. Furthermore, using steel formwork significantly reduces pore water pressure and air bubble generation during concrete pouring, resulting in a more ideal surface quality, allowing for subsequent construction stages without the need for additional roughing treatment.

[0003] Despite this, traditional steel formwork systems still face several challenges in practical applications. First, the connection methods between formwork panels are relatively fixed, lacking flexibility and making it difficult to adapt to different angle requirements. For example, in railway bridge construction, the angle of the formwork often needs to be adjusted according to specific design requirements to meet the needs of various complex structural shapes. Second, existing formwork systems are complex and time-consuming to assemble and disassemble, increasing labor costs and project timelines. This inefficiency is particularly pronounced in large-scale infrastructure projects. Furthermore, some formwork systems have limited applicability and cannot flexibly respond to changes in the construction site, causing inconvenience to construction.

[0004] To address the aforementioned problems, this utility model proposes a rapid assembly and combination structure for steel formwork of railway bridges. Utility Model Content
