Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel structure connection, in particular to an oblique circular steel pipe connection node structure. Background Art
[0002] Since the upper beams of cable-stayed bridges and suspension bridges have large spans and high altitudes, bracket construction methods are often used. In order to reduce the calculated span of the upper beam, the brackets are often equipped with round steel pipe diagonal braces. One end of the diagonal brace supports the formwork bracket, and the other end supports the tower column corbel support. In addition to generating a large vertical downward force on the tower column, it also generates a large horizontal thrust, which can easily cause the support to slide and cause dangerous accidents. Traditional steel structure round steel pipe oblique nodes only use intersecting line welding. However, there is a certain error when cutting the intersecting line, which is not convenient for welding, resulting in difficulty in ensuring the connection strength between steel pipes.
[0003] A better solution is to set a tie rod between two diagonal braces and use a horizontal tie rod to offset the horizontal thrust. However, during use, since the support angle of each stage is different, the diagonal brace angle of the steel pipe needs to be adjusted appropriately according to the position of each stage. However, the welded diagonal brace steel pipe cannot be accurately adjusted to adapt to the change in stage angle, which will result in the diagonal brace steel pipe being unable to provide the maximum support when supporting.
