Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a stable support system for the cantilever formwork of I-beams used in bridge construction. Background Technique

[0002] As a key transportation infrastructure, bridges play an irreplaceable role in supporting the national economy and social development. With the increasing transportation demand, the scale and complexity of bridge construction are also constantly rising, which puts more stringent standards on bridge construction technology. Among various bridge types, cast-in-situ concrete bridges are the most widely used due to their structural stability and durability. The construction technology of cast-in-situ concrete bridges is relatively complex, with high technical requirements, and highly dependent on the professional skills of construction personnel and the performance of construction equipment. Traditional construction methods for cast-in-situ concrete bridges mainly include the falsework construction method, the cantilever construction method, the slip form construction method, etc. These methods have their own advantages, but also have certain limitations.

[0003] The falsework construction method relies on a large number of falseworks and formworks, which need to be frequently erected and disassembled during the construction process, increasing the complexity and cost of construction. The cantilever construction method requires gradual extension of construction at both ends of the bridge, but this method has high requirements for construction equipment and technology, and a long construction period. Although the slip form construction method can speed up the construction speed, it has extremely high requirements for the construction environment and the control of construction accuracy. In the existing construction technology, a common problem is the combination method relying on the inner counterweight and the outer cantilever suspended formwork. Although this method can ensure the construction stability to a certain extent, it also brings problems such as a large number of equipment, complex operation, and frequent turnover of formworks. These factors not only prolong the construction period, increase the cost, but also may increase the construction difficulty due to heavy counterweight blocks and complex external support systems, affect the operation safety, and limit the construction efficiency and quality control.
