Description

Oblique circular steel tube connection node structure

Technical Field

The utility model relates to a bridge construction technical field especially relates to an oblique crossing circular steel tube connected node structure.

Background

Because the span of the upper beam of the cable-stayed bridge and the suspension bridge is large, the altitude is high, and a bracket construction method is mostly adopted. In order to reduce the calculation span of the upper crossbeam, the bracket is provided with a round steel tube inclined strut. Bracing one end supports the template support, and one end supports on the tower column bracket support, except producing great vertical decurrent power to the tower column, still can produce great horizontal thrust simultaneously, leads to the support to slide very easily and takes place dangerous accident.

The pull rod is arranged between the two inclined struts, and the horizontal thrust is offset by the horizontal pull rod, so that a better solution is achieved. Because the force transmission of the inclined leg support is large, the inclined leg support and the pull rod both adopt circular sections with good stability, and therefore the design problem of the connection node of the inclined circular steel tube is generated. The traditional steel structure circular steel tube oblique crossing joint only adopts intersecting line welding, and the mode has two defects, namely, certain error exists during intersecting line cutting, welding is inconvenient, and the connection strength between steel tubes is difficult to guarantee; and secondly, the contact surface of the round steel pipe after the oblique crossing and the support is a cutting circular section, and the yield failure is easy to occur under the action of huge support reaction force.
