Abstract

The invention provides a pitching type truss bridge manufacturing method. A pitching type truss bridge comprises a bridge deck and truss side pieces located on two sides of the bridge deck, wherein a hinge point is arranged at one end of the pitching type truss bridge. The pitching type truss bridge manufacturing method comprises the steps of dividing the truss side pieces into multiple truss sections according to the Z-direction camber demand of the pitching type truss bridge, wherein each truss section is linear; respectively manufacturing the multiple truss sections and cutting closing-up allowances of the multiple truss sections according to the Z-direction camber demand, dividing the bridge deck into the multiple truss sections to be manufactured respectively; sequentially splicing the multiple truss sections and multiple bridge decks together. The pitching type truss bridge meeting the Z-direction camber demand can be manufactured by means of the simple method.

Description

technical field

[0001] The present invention relates to a manufacturing method of a pitched truss bridge. Background technique

[0002] Pitching truss bridge is a commonly used steel bridge structure, which usually includes bridge deck, truss, top brace, bicycle lane, straight cylinder and counterweight box. The hinge points of the steel bridge are set on the trusses on both sides, which can be opened and closed by rotating the hinge system. Bicycle lanes and train tracks can be set up on the bridge deck, and the straightness and height difference of the train tracks are required to be high.

[0003] When the size of the pitching truss bridge is large, for example, the overall length is about 100 meters, the width is about 20 meters, and the height is about 22 meters, and the manufacturing process becomes very difficult. In particular, when the pitched truss bridge has preset camber requirements in the X-direction and / or the Z-direction, the manufacturing method becomes mo...
