Description

A kind of bridge arch rib section manufacture craft

Technical field

The invention belongs to bridge manufacturing technology field, more particularly to a kind of bridge arch rib section manufacture craft.

Background technology

With China railways, expressway construction project it is increasing, built in the poor deep mountain valleys of natural conditions The engineering of bridge is more and more, especially long-span steel arch bridge, because the structure is particularly suitable for paddy and flows anxious, construction environment deeply Severe plateau narrow valley region.Therefore for the preparation method of bridge arch rib, also it is taken seriously more and more, especially for Execution conditions adverse conditions, then its preparation method be just particularly important.

In the bridge that the present invention is studied, main bridge is using the double-deck trussed bridge of half-through, and span setting is 496m, bridge main line It is divided into upper and lower two layers by function, upper deck of bridge service motor vehicle, beam overall 33m;Lower floor's bridge service slow-vehicle system, width 12m is main 108m lower floors bridge floor can be removed by being suspended on the vertical shift track at upper deck of bridge beam bottom to both sides in spanning, to meet 500t grades Ship navigation requirement;In usually lower floor's bridge floor closure state, beam bottom about 300m scopes meet yacht navigational clearance height;And Arch rib therein section is also indispensable structure composition in bridge.Found through retrieval, China Patent No. is 201310367055.1 proposing a kind of bridge arch rib preparation method, comprise the following steps:1)Blanking typesetting;2)Blanking;3)Volume Pipe;4)Group weldering internal stiffeners;5)Put ground sample, assembling steel pipe;6)Boom location is determined, using dotting punch as mark;7)Boom location Erection support is simultaneously welded;8)Welded pipe and pipe butt weld;9)Group weldering arch rib;10)Horizontal, bearing diagonal makes;11)Sectional making is simultaneously Carry out preassembling;12)Mark is carried out at arch rib segmentation position, it is same to connect first code;13)Paint;Using the invention Method, in carrying out the making of bridge arch rib and be assembled, simplifies flow, while assembled and welding quality is also significantly increased, The construction quality of bridge arch rib is greatly ensured;But the preparation method has the following disadvantages:1. the bridge arch rib preparation method, Steel pipe is used, but steel tube section is more using steel, and manufacture relative complex, connection is inconvenient;2. the preparation method, no It can meet to the assembled requirement made of arch rib section multi-segmental matching, while in arch rib section manufacturing process, line style camber requires high, But the preparation method is difficult to control line style camber.

Therefore, developing the bridge arch rib section manufacture craft that a kind of preparation method is simple and convenient to operate and line style precision is high is It is highly desirable to.

The content of the invention

It is simple and convenient to operate the technical problem to be solved in the present invention is to provide a kind of preparation method and the high bridge of line style precision Camber rib section manufacture craft.

In order to solve the above technical problems, the technical scheme is that:A kind of bridge arch rib section manufacture craft, its innovative point It is:The manufacture craft is specific as follows:
