Description

Technical Field

[0001] The utility model relates to bridge construction technology, and more specifically, to an adjustable combined falsework. Background Art

[0002] At present, as bridge construction is moving towards large-scale and complex, the complex and diverse building structures pose important challenges to construction technology. Most existing large-scale bridges are built in sections, which not only saves a large amount of cost but also a large amount of time. The most commonly used equipment for sectional construction is the falsework. However, most of the falseworks on the market are fixed in a specific area for work in the form of welding. Once leaving this area, a new falsework needs to be built to maintain work, which is not only time-consuming and laborious but also costly. If a non-welded falsework is used, the stability is insufficient and it is prone to tipping over. Moreover, there are few falseworks on the market that support the construction of bridges of different models, because the height and inclination of most falseworks are not adjustable, which leads to the need for different falseworks to operate under different working conditions.
