Abstract
The utility model provides a 2# supporting leg of a bridge erecting machine, which is provided with a multilayer 'distribution girder-cup support' structure. A cup support structure comprises a front cup support and a back cup support. The front cup support is supported in a groove area at the end part of a bottom plate of a U-shaped concrete girder which is located at a position of an invisible cover girder of the top of the cup support; the back cup support is supported on the erected U-shaped concrete girder; the front cup support and the back cup support are respectively provided with a front supporting point distribution girder and a back supporting point distribution girder; and a vertical distribution girder is connected between the front supporting point distribution girder and the back supporting point distribution girder. By using a layered transition structure by the 2# supporting leg disclosed by the utility model, the multilayer 'distribution girder-cup support' structure is arranged to ensure uniform load distribution. The front cup support is directly supported on the invisible cover girder at the top of the cup support, so that about a half of the construction load is directly transmitted to a foundation through the pier without passing through the U-shaped concrete girder. Therefore, the problem that the own structure of the U-shaped concrete girder cannot bear larger concentration force is solved, so as to satisfy the bearing capability designed for the thinner bottom plate of the U-shaped concrete girder.
