Longitudinal temporary limiting device for cable-stayed bridge tower top
The invention discloses a longitudinal temporary limiting device for a cable-stayed bridge tower top. The device is arranged between a tower body and a main beam, two tower body limiting blocks are symmetrically arranged at the top end face of the tower body, and a main beam limiting block located between the two tower body limiting blocks is arranged on the bottom end face of the main beam. A supporting mechanism is arranged between the tower body and the main beam. The limiting device is characterized in that the limiting device comprises two symmetrically-distributed supporting piers, the two supporting piers are located between the two tower body limiting blocks, the top end faces of the supporting piers make contact with the bottom end faces of the main beam limiting block, and cushion blocks and lifting cushions are arranged between the tower body limiting blocks and the main beam limiting block; and the bottom end faces of the cushion blocks and the lifting cushions are in contact with the supporting piers. The limiting device further comprises two bearing beams distributed at the outer sides of the tower body limiting blocks, and the two bearing beams are connected into a whole through finish rolling deformed steel bars.
本发明公开一种斜拉桥塔顶的纵向临时限位装置，所述的限位装置设置在塔身和主梁之间，在塔身的顶端面上对称地设置有两个塔身限位块，在主梁的底端面上设置有位于两个塔身限位块之间的主梁限位块，塔身与主梁之间还设置有支撑机构，其特征在于：所述的限位装置包括两个对称分布的支撑墩，这两个支撑墩位于两个塔身限位块之间，且支撑墩的顶端面与主梁限位块的底端面接触，在塔身限位块和主梁限位块之间设置有垫块和抄垫，且所述垫块和抄垫的底端面与支撑墩接触，所述的限位装置还包括两个分布在塔身限位块外侧的垫梁，这两个垫梁通过精轧螺纹钢连接为一体。
