A connecting node for connecting rods of steel structure bridges

Abstract

The invention relates to the technical field of bridge connection nodes, and discloses a connection node for steel structure bridge connecting rods, comprising: an upper box body, a first through screw hole is provided on the top, and a plurality of connecting rod upper positioning holes are provided on the bottom circumference A plurality of first positioning grooves; the lower box body, a plurality of second positioning grooves for positioning the lower parts of a plurality of connecting rods are provided in the top circumference, and a cavity is provided in the box body formed after the lower box body and the upper box body are fastened. The bottom of the body is provided with a second through-screw hole, and the lower part of the lower box body is horizontally provided with a through-slot, and the second through-screw hole intersects with the through-slot vertically; the positioning plate passes through the through-slot, and the positioning plate is provided with a first positioning screw hole and a plurality of second positioning screw holes; the positioning connecting column passes through the first through screw hole, the connection ends of a plurality of connecting rods, the first positioning screw hole and the second through screw hole from top to bottom and passes through the lower box The body is bolted to the corresponding screw holes on the steel structure bridge. This kind of connection node used for the steel structure bridge connecting rod is mutually socketed and restrained. The structure is stable and the appearance is beautiful.

Description

technical field [0001] The invention relates to the technical field of bridge connection nodes, in particular to a connection node used for steel structure bridge connecting rods. Background technique [0002] With the development of society, the transportation is more and more developed. People build bridges between rivers or mountains to facilitate the transportation of goods and communication. [0003] The construction of steel structure bridges is fast and has been widely used. Steel structure bridges use nodes to connect various connecting rods. The connecting rods include suspenders and oblique rods. The stability of the connection nodes between suspenders and oblique rods will affect the stability of steel structure bridges. , Most of the existing connection nodes use bolts or welding to connect the connecting rods. The strength of the structure is not good and it is easy to be damaged. Therefore, there is an urgent need for connection nodes of steel structure bridge ...

[0003] The construction of steel structure bridges is fast and has been widely used. Steel structure bridges use nodes to connect various connecting rods. The connecting rods include suspenders and oblique rods. The stability of the connection nodes between suspenders and oblique rods will affect the stability of steel structure bridges. , most of the existing connection nodes use bolts or welding to connect the connecting rods. The strength of the structure is not good and it is easy to be damaged. Therefore, there is an urgent need for connection nodes of steel structure bridge connecting rods with a stable structure to meet people's needs.
