Embodiment Construction

[0025] The invention provides a joint construction method of a steel truss bridge using bolts, welding and riveting, which is suitable for the construction of the joints of a steel truss bridge. The node of the steel truss bridge in the present invention is not provided with a gusset plate, and the web is connected with the web to form the node of the steel truss bridge. The present invention adopts three connection modes of high-strength bolt connection, weld seam connection and rivet connection. Among them, the factory manufacturing parts are connected by high-strength bolts and welds, and rivets are used for on-site assembly. In the construction method proposed by the present invention, the steel truss bridge nodes are only connected by rivets between the web and the chord at the construction site, which reduces the on-site construction links, and the force of the overall nodes is clear, which reduces the construction difficulty and can enhance the appearance under the cond...

Abstract

The invention discloses a steel truss bridge joint construction method using bolting, welding and riveting combination. The method comprises the following steps of 1, manufacturing a flange plate, webplates, web-plate outer flitch plates and web rod sets respectively; 2, forming holes in the flange plate, the web plates, the web-plate outer flitch plates and the web rod sets according to the design size; 3, welding the flange plate and the web plates to form chord members through welding seams; 4, fixedly arranging the web-plate outer flitch plates on the outer side faces of the web plates, and connecting the web plates to the chord members to form reinforced chord members; 5, after the reinforced chord members are installed on a bridge location on site, riveting the web rod sets with theweb plates and the web-plate outer flitch plates through rivets to form steel truss bridge joints. According to the construction method, the steel truss bridge joints are subjected to rivet and welding seam connection construction in a factory and bolt connection construction on a construction site, the on-site construction links are reduced, the overall joint stress is clear, the construction difficulty is reduced, and the cost is reduced on the condition of meeting the strength.

Description

technical field [0001] The invention relates to a construction method for a steel truss bridge, in particular to a construction method for joints of a steel truss bridge connected by bolts, welding and riveting. Background technique [0002] Steel truss bridges have the characteristics of strong spanning capacity, fast construction speed, large bearing capacity, and good durability. Composed of compression rods, the force on the rods is clear. Steel truss construction generally adopts factory-made rods and assembled on site, which has a short construction period and high speed, and is widely used in bridge engineering. There are mainly two ways to connect the members of the steel truss bridge: high-strength bolt connection and rivet connection. [0003] High-strength bolt connection is suitable for ultra-high pressure occasions. In the existing steel truss bridges, most of the members are connected by high-strength bolts. In the specific construction, a large prestress sho...
