Description

[0002] At present, with the rapid development of modern construction, each city is increasing the traffic convenience of the city by building roads and bridges, thereby driving the economic development within the city. The construction of roads and bridges is inseparable from formwork support. Common formwork materials include plastics, wooden boards, and steel plates. Since plastics have low strength and are used in fewer occasions, and wooden boards are prone to decay, resulting in an increased consumption rate and increased costs, the use of formwork is also decreasing. Steel plates are used in the production of formwork in various fields due to their strong corrosion resistance, high strength, and high reusability. Especially in the construction of roads and bridges, steel formwork is used for pouring piers, bridge bodies, road surfaces, etc. During the use of steel formwork, after the poured body has a certain strength, the steel formwork needs to be disassembled. During the disassembly process, first, the steel formwork needs to be removed from the poured body. For example, the Chinese invention patent with the patent number CN 111197285 B discloses a device for removing formwork of road and bridge steel formwork. When this formwork removal device removes the formwork, it directly and forcibly separates the formwork from the poured body. Such formwork removal not only has low efficiency, but also requires relatively high strength and power for the formwork removal device.
