Bridge with section in double-X shape

Abstract

The invention relates to the technical field of bridges, in particular to a bridge with the section in a double-X shape. The bridge comprises a bridge body which is composed of a first X-shaped beam body and a second X-shaped beam body symmetrical to the first X-shaped beam body. The first X-shaped beam body is composed of a left side inclined protection plate, a first protruding bar seat, a first X-shaped supporting beam, a first base, a first bridge deck, right side triangular supporting beams and first supporting columns, wherein the first X-shaped supporting beam is arranged between the first base and the first bridge deck, the left side inclined protection plate is arranged on the left side of the surface of the first bridge deck, the first protruding bar seat is arranged on the left side of the surface of the first base, the first supporting columns are arranged on the first protruding bar seat, and the other ends of the first supporting columns are connected with the left side of the bottom face of the first deck. The combined double-X beam bodies are adopted, the bridge is simple in structure and convenient to combine, the loading capability of the bridge is greatly improved, the vertical rigidity and the stress degree of the bridge are improved, and the service life of the bridge is prolonged.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a bridge with double X-shaped cross sections. Background technique [0002] Bridges are generally composed of superstructure, substructure, bearings and subsidiary structures. It generally refers to structures erected on rivers, lakes and seas to enable smooth passage of vehicles and pedestrians. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. In today's society, with the continuous improvement of people's living standards, people's income has also increased accordingly. The means of transportation used by people has also undergone major changes, and automobiles have entered thousands of households as a means of transportation. In addition, changes in the socio-economic structure and the deve...

Problems solved by technology

In particular, some heavy transport vehicles (such as trains, large trucks, etc.) have a greater impact on the bridge deck, which aggravates the fatigue damage of the bridge structure, thereby affecting the overall performance of the bridge and shortening its service life.
