Connecting joint for steel structure bridge connecting rod

Abstract

The invention relates to the technical field of bridge connecting joints, and discloses a connecting joint for a steel structure bridge connecting rod. The connecting joint comprises: an upper box body, wherein a first through screw hole is formed in the top of the upper box body, and a plurality of first positioning grooves for positioning the upper part of a plurality of connecting rods are formed in in the circumferential direction of the bottom of the upper box body; a lower box body, wherein a plurality of second positioning grooves for positioning the lower parts of the plurality of connecting rods are formed in the circumferential direction of the top of the lower box body, a cavity is formed in a box body formed after the lower box body and the upper box body are buckled, a secondthrough screw hole is formed in the bottom of the lower box body, a through groove is horizontally formed in the lower part of the lower box body, and the second through screw hole is vertically intersected with the through groove; a positioning plate which penetrates through the through groove, and is provided with a first positioning screw hole and a plurality of second positioning screw holes;and a positioning connecting column which sequentially penetrate through the first through screw hole, the connecting ends of the connecting rods, the first positioning screw hole and the second through screw holes from top to bottom and penetrate out of the lower box body to be connected with corresponding screw holes in the steel structure bridge in a bolted mode. The connecting joint for the steel structure bridge connecting rods is mutually connected in a sleeved mode, mutually restrained, stable in structure and attractive in appearance.

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.
