Large steel structure bridge joint connection mechanism convenient to stably connect

Abstract

The invention discloses alarge steel structure bridge joint connection mechanism convenient to stably connect. The large steel structure bridge joint connection mechanism comprises a first cross beam,a connecting sleeve, a second cross beam and a bottom column, an installation plate is fixed to the bottom end of the bottom column, and a top plate is fixed to the central position of the top of thebottom column through a supporting column; first connecting rods are fixed to the top ends of the two sides of the supporting column correspondingly, and second connecting rods are fixed to the bottom ends of the two sides of the supporting column correspondingly; the ends, away from the supporting column, of thesecond connecting rods are connected with the ends, away from the supporting column,of the first connecting rods correspondingly, the connecting sleeve is installed at the top end of the top plate, and a silicon carbide wear-resisting layer is arranged on the outer side of the connecting sleeve. According to the large steel structure bridge joint connection mechanism convenient to stably connect, the connecting sleeve, preformed grooves, the first cross beam, the second cross beam, angle steel and fixing bolts are installed, thus the ends, close to the connecting sleeve, of the first cross beam and the second cross beam are conveniently inserted into the preformed grooves andfixedly connected through the angle steel and the fixing bolts, and the large steel structure bridge joint connection mechanism is fixedly installed and disassembled conveniently.

Description

technical field [0001] The invention relates to the technical field of bridge node connection mechanisms, in particular to a large-scale steel structure bridge node connection mechanism that is convenient for stable connection. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountains, poor geology, or meet other traffic needs to make traffic more convenient. As the name implies, large steel structure bridges are steel bridges. [0003] Large-scale steel structure bridges usually use the form of node connection to connect various parts. The strength of the node connection mechanism directly affects the safety and service life of the steel structure bridge. However, most of the existing node connection mechanisms have poor structural strength and comp...
