Problems solved by technology

[0003] When the size of the pitching truss bridge is large, for example, the total length is about 100 meters, the width is about 20 meters, and the height is about 22 meters, the manufacturing process will become very difficult
Especially when the pitching truss bridge has preset camber requirements in the X and / or Z directions, the manufacturing method becomes more difficult

Embodiment Construction

[0035] The present invention will be further described below with reference to specific embodiments and accompanying drawings, but the protection scope of the present invention should not be limited by this.

[0036] The manufacturing method of the pitch truss bridge according to the present embodiment includes the following steps:

[0037] According to the Z-direction camber requirement of the pitching truss bridge, the truss side piece is divided into a plurality of truss segments, and each truss segment is linear;

[0038] The plurality of truss segments are respectively made, and the closing margin of each truss segment is cut according to the Z-direction camber requirement;

[0039] The bridge deck is divided into a plurality of bridge deck segments to be produced separately;

[0040] The plurality of truss segments and the plurality of bridge deck segments are sequentially assembled together.

[0041] The following describes in detail with reference to the accompanying...

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...
