A bridge deck structure for arch bridge engineering

Abstract

The invention discloses a bridge deck structure of an arch bridge engineering, which comprises a middle section and a support section, and the middle section and the support section both include a first I-beam, and one side of the inner surface of the first I-beam is clamped A second I-beam is connected, the top of the second I-beam is fixedly connected with a first steel bar, and the surfaces of the first I-beam and the second I-beam are both provided with first pin holes, which involves bridge engineering technology field. The bridge deck structure of the arch bridge project is processed separately from the middle section and the support section, and connected by connectors, so that the internal main structure of the arch bridge deck part is easy to process and transport. Through the first I-beam, the second The splicing design of the second I-beam and the first steel bar, as well as the design of the internal cavity and support frame of the connecting piece, provide a strong supporting capacity for the bridge deck structure, and the splicing is simple, the work efficiency is high, and it can be used in other places After the splicing is completed, concrete is laid on the ground, which is less affected by the weather.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a deck structure of an arch bridge engineering. 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 buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head board, conical slope prote...
