Description

Technical Field

[0001] The utility model relates to the technical field of construction facilities, in particular to a novel curved section anti-collision wall template device. Background Art

[0002] Crash barriers play a vital role in road safety. Serving as a sturdy barrier, they effectively protect the lives of pedestrians and drivers. Constructed from cast steel formwork, these walls possess exceptional strength and toughness, effectively withstanding impacts from high-speed vehicles and minimizing potential injuries to pedestrians and drivers. Through their superior protective properties, crash barriers not only reduce the severity of traffic accidents but also, to a certain extent, prevent secondary accidents, ensuring safe and smooth road traffic.

[0003] The existing formwork design for crash barriers primarily consists of inner and outer molds and upper and lower tension structures. While this design performs well during the casting of straight sections of crash barriers, ensuring the straightness and flatness of the wall, when it comes to casting curved sections, the design flaws of the existing formwork become apparent. Due to the limitations of the formwork structure, it is often difficult to achieve a smooth arc transition when casting curved sections. This not only affects the overall aesthetics of the crash barrier, but more importantly, this discontinuous arc cannot guarantee that the crash barrier has the same shape and size at all locations, which in turn affects the consistency and stability of the crash barrier and may not provide the expected protection in the event of a collision. Therefore, how to improve the existing formwork design to adapt to the needs of various complex road sections has become the key to improving the overall performance of the crash barrier.
