Technical Field

[0001] The utility model relates to the technical field of bridge deck construction, in particular to a bridge deck slipform construction unit outside an I-beam and a matching construction system thereof. Background Art

[0002] In highway bridge projects, pre-tensioned I-beams are widely used, but the construction of their outer bridge decks has always been a technical problem. Traditional construction methods such as the hanging formwork method and the inner counterweight and outer cantilever hanging formwork construction method have many shortcomings, such as low construction efficiency, complex material turnover, large investment in manpower and material resources, and high costs.

[0003] The root cause of these traditional methods is that since the bridge deck extends beyond the I-beam, it is impossible to set up scaffolding underneath for construction. Specific problems include: the construction scaffolding is cumbersome to set up and remove, which increases construction time and cost. The turnover of formwork materials is inconvenient and requires frequent adjustments to accommodate I-beams of different sizes. A large amount of counterweights are required during the construction process, which increases the complexity of the construction and safety hazards. The construction progress is limited, especially during the bridge deck construction stage, making it difficult to achieve rapid and continuous construction.

[0004] How to solve the above technical problems is the subject faced by the present utility model. Summary of the invention
