Abstract

The invention discloses a bridge of steel truss-concrete structure and a construction method thereof, wherein the bridge comprises a steel truss and a bridge deck of concrete material, the bridge deck is connected with an upper chord of the steel truss by shear nails; spreader bars are fixed between nodes of the upper chord. When constructing, the bridge deck is prefabricated, and then bridge deck is installed onto the erected steel truss by shear nails. The bridge of the invention combines steel and concrete by each feature, and has advantages of both materials; the structure has good integrity and strong wind resistance capability, needs no connect to parallel. The bridge has simple structure, smooth line and low cost, because the concrete slab has big self-bearing capacity and vertical and horizontal beams and connect to parallel are not needed. Besides, the concrete bridge deck slab of the invention can enhance structural stiffness, improve variation because of temperature differential, decrease infection on bridge deck of freeze-thaw in north coldness area, and improve running environment of vehicle at bad weather.

Description

technical field [0001] The invention relates to the technical field of bridge construction engineering, in particular to a steel truss-concrete structure bridge without longitudinal and horizontal beams, and also relates to a construction method of the bridge. Background technique [0002] With the large-scale investment and construction of infrastructure in my country, how to ensure the safe use of structures while maximizing economic benefits has become a problem that must be solved in the engineering field. Bridges are one of the projects with the highest technical content and the most complex technical requirements in the engineering field. The goal of bridge construction is to build a durable, economical and functional bridge structure. This will inevitably require continuous innovation, development and advancement of bridge construction technology. [0003] Among various bridge structures, there are mainly two types according to the classification of construction mater...
