Description

Technical Field

[0001] The utility model relates to the field of precast beams, and particularly to an automatic removal device for the end formwork of precast beams. Background Art

[0002] In the construction of bridge assembly, the upper structure usually adopts precast construction. The T-beam is a relatively common structure. The precast of the T-beam is constructed by the T-beam formwork. The main components of the T-beam module mainly include side formwork, end formwork and bottom formwork.

[0003] After the concrete of the beam body is poured, the end formwork embedded in the side formwork and the bottom formwork needs to be removed before the side formwork and the bottom formwork are removed. Traditional operations require manual use of tools such as crowbars and sledgehammers to knock and remove, which is not only difficult to remove, but also slow in speed and easy to damage the beam body concrete. And after the end formwork is removed, it is necessary to use a gantry crane to move and place the end formwork for storage.

[0004] The existing automatic removal equipment on the market generally removes the end formwork by moving it linearly, but in fact, the end formwork needs to move obliquely upward when being removed; the existing automatic removal equipment on the market still needs manual operation to lay down the end formwork for storage after removing the end formwork. The end formwork is large in volume and heavy in mass, and accidents are likely to occur during manual removal; therefore, there is an urgent need for an automatic removal device for the end formwork of precast beams that does not damage the beam body concrete, is fast in removal, and is simple and convenient. Content of the Utility Model
