Description
Technical field
The utility model relates to the welding technology fields of U rib, and in particular, to a kind of embedding benefit section welding structure of U rib.
Background technique
Steel box-girder is the important component in bridge bearing structure, and steel box-girder is generally Orthotropic Steel Bridge Deck, main
It is used to provide support, avoids bridge deformation.Steel box-girder generally comprises the structures such as top plate and bottom plate, and the top plate and bottom plate are general
It is welded by U rib and bottom plate.
Currently, bridge U-rib can use interior welding technology, two-sided welding is realized, U rib and panel are greatly improved
The fatigue life of welding point.It since steel box-girder is generally longer, needs to connect in multiple U ribs, U rib is connected in building-site
When, generally use two methods: 1. use splice bar bolting mode, and the method anti-fatigue performance is superior, site construction letter
It is single, but make trouble, high production cost, and bolt is in the long-term use, can partially loosen, falls off, destroy,
Hidden danger of quality is caused, especially lower section passing vehicle or when train, great security risk will be caused.2. embedding using U rib
Section is mended, is welded to connect at the scene.This method manufacturing cost is low, and building site connection is reliable, and safety accident will not occur, but often
For the embedding benefit section of rule since inside cannot weld, inside has natural notch, and the local fatigue service life is lower.
Utility model content
The purpose of this utility model is exactly to propose a kind of the embedding of U rib to improve the U rib embedding local fatigue service life for mending section
Mend section welding structure.
The utility model is achieved through the following technical solutions.
A kind of embedding benefit section welding structure of U rib, comprising: the first U rib unit；2nd U rib unit；Bottom plate；The first U rib
Unit and the 2nd U rib unit along its length on be sequentially welded in the same side of the bottom plate, the first U rib unit
There is default spacing between the 2nd U rib unit；
Embedding benefit section, the embedding benefit section be embedded between the first U rib unit and the 2nd U rib unit and respectively with institute
State the first U rib unit and the 2nd U rib element solder connection；

Top connecting plate and the top plate of the first U rib unit and the 2nd U rib unit are end to end；
Wherein, first side plate and second side plate elder generation and the bottom plate and the first U rib unit, described second
After U rib element solder is fixed, then by the top connecting plate be welded in the first U rib unit and the 2nd U rib unit it
Between.
Since traditional embedding benefit section is due to being enclosed construction, fillet weld can only be out of outside progress single-sided welding, U rib
Side does not have weld seam, there is natural notch together, anti-fatigue performance is poor, and the fillet weld at the other positions of U rib all realizes welding by both sides
It connects, fatigue life is high, if embedding benefits section is single welding, is bound to cause U rib embedding benefit section local fatigue service life low short slab.Cause
This can respectively be connected two sections of U ribs by the above-mentioned technical proposal of the utility model by the first side plate and the second side plate respectively
It picks up and, internal and outer double can be implemented respectively and welded, be open when being equivalent to two side plates of welding, it is possible to from
By implementation two-sided welding, and its top due to stress it is smaller, top blind flange weld when can after the completion of two plate-side plate weldings, from
Outside weldings are in place.
Based on the above technical solution, the utility model can also have following preferred technical solution.
Preferably, the embedding U-shaped rib for mending the first U rib unit described in Duan Weiyu and the 2nd U rib unit same size,
Two side plates and top plate of the U-shaped rib correspond respectively to first side plate, second side plate and the top connecting plate,
