Description

Technical Field

[0001] The utility model relates to the technical field of bridge formwork, in particular to a separation device for bridge formwork. Background Art

[0002] During the construction of bridges, concrete pouring is often required. During the pouring process, bridge formwork is needed, that is, steel formwork widely used in bridge projects for shaping. After the bridge formwork is used, it needs to be removed, disassembled and recycled. This process requires the use of separation equipment.

[0003] After searching, the patent number CN202323319183.7 discloses a separation device for bridge formwork. When in use, this solution controls the movement of the first connecting rod and the second connecting rod through a telescopic mechanism, and then realizes the direct removal of the bridge formwork through a card joint. This solution directly controls the removal of the formwork through the telescopic mechanism. This removal method is not labor-saving enough, and is likely to cause damage to the equipment, which increases the cost in disguise. It cannot be more labor-saving and convenient to remove the formwork, and it needs to control the movement of the connecting rod through a telescopic mechanism. The telescopic mechanism is generally hydraulically driven, which is not convenient for on-site use, and therefore needs to be improved. Utility Model Content
