Reinforced bridge steel structure

Abstract

The invention discloses a reinforced bridge steel structure, and belongs to the technical field of bridge steel structures. According to the reinforced bridge steel structure, the connecting plates below the supporting rods are hinged to the embedded parts at multiple angles, the reinforcing rods are adopted between the supporting rods to form a connecting net, connection is stable, the steel structure is not prone to falling off, the overall firmness of the steel structure can be effectively guaranteed, and the service life of a bridge is prolonged; the waterproof ring is arranged at the joint of the rod body and the connecting plate, rainwater is prevented from corroding the steel structure, and the service life is prolonged; the signal lead is additionally arranged in the steel cable structure, when the signal lead is broken, the signal lamp is extinguished, a maintainer is reminded to overhaul the steel cable in time, early warning of steel cable breakage is achieved, and the safety of the bridge steel structure is improved.

Description

technical field [0001] The invention relates to the technical field of bridge steel structures, in particular to a reinforced bridge steel structure. Background technique [0002] The main load-bearing structure of bridge steel structure is made of steel, that is, steel structure bridge and steel bridge. The main design concept of the steel structure bridge is to assemble the least types of unit components into a prefabricated steel bridge capable of carrying various loads and different spans, and only need to be transported by ordinary medium-sized trucks. In special cases, it can be built entirely by manpower. Therefore, steel structure bridges have been widely used in urban infrastructure construction. At present, the existing bridge steel structures usually have the following defects during use: 1. The existing bridge steel structures usually have poor stability and low strength. 2. The installation effect of the existing steel structure is poor, the connection is unst...

AI Technical Summary

Problems solved by technology

At present, the existing bridge steel structures usually have the following defects during use: 1. The existing bridge steel structures usually have poor stability and low strength. 2. The installation effect of the existing steel structure is poor, the connection is unstable, and the joints of the steel structure are prone to fall off due to force, and the steel structure is prone to corrosion fatigue and cause fracture. The safety is poor, which affects the overall stability of the steel structure of the bridge; 3. In the existing steel structure, steel cables are used to strengthen the connection. The steel cables are formed by winding several steel cable units. The strength of the steel cables is particularly important in the structure. If the steel cable breaks and is not replaced in time, it will affect the overall strength of the rigid structure, and in serious cases, a safety accident will occur. However, in the prior art, there is no early warning structure for steel cable breakage
