Asymmetric pyramid shaped bridge tower

The utility model relates to an asymmetric pyramid shaped bridge tower belongs to the bridge tower structure of the novel cable -stay bridge of water conservancy project. King -post bottom respectively with respective tower mound fixed connection, the top of the tower intersect at the top, tower mound and bridge tower basis fixed connection, horizontally roof beam interconnect is passed through to bridge tower counter weight position in the top of the bridge tower basis between the tower mound between each king -post, wherein king -post no. 1 is connected through roof beam no. 1 between two with the king -post, king -post no. 2 is connected through roof beam no. 2 between three with the king -post, king -post no. 3 is connected through roof beam no. 3 between four with the king -post, king -post no. 4 is connected through roof beam no. 4 between one with the king -post, roof beam no. 2, roof beam quartering do not be two perpendicular with the bridge axis of the bridge axis of bridge floor no. 1, bridge floor no. 2, bridge floor no. 1, bridge floor policy of "literature and art should serve both people and socialism" broken line bridge floor. The advantage is novel structure, sets up side direction that counter weight district both can keep balance the transmission of the broken line bridge floor load that topples, can also keep balance the unsymmetrical loading that asymmetric bridge floor transmitted, can be used to water conservancy project structural design under the non - symmetrical arrangement circumstances.
