Description
Technical field
The present invention relates to the welding technology fields of U ribs, and in particular, to a kind of embedding benefit section welding structure of U ribs.
Background technology
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 ribs and bottom plate.
Currently, interior welding technology has may be used in bridge U-rib, two-sided welding is realized, greatly improves U ribs and panel
The fatigue life of welding point.It since steel box-girder is generally longer, needs to connect in multiple U ribs, U ribs are connected in building-site
When, generally use two methods：1. using splice bar bolting mode, the method anti-fatigue performance is superior, site construction letter
It is single, but make trouble, production cost is high, and bolt is in the long-term use, can partly loosen, falls off, destroy,
Hidden danger of quality is caused, especially the current vehicle in lower section or when train, great security risk will be caused.2. embedding using U ribs
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, local fatigue service life relatively low.
Invention content
The purpose of the present invention is exactly to improve the U ribs embedding local fatigue service life for mending section, it is proposed that a kind of embedding benefit section of U ribs
Welding structure.
The present invention is achieved through the following technical solutions.
A kind of embedding benefit section welding structure of U ribs, including：First U rib units；2nd U rib units；Bottom plate；The first U ribs
Unit and the 2nd U ribs unit along its length on be sequentially welded in the same side of the bottom plate, the first U rib units
There is default spacing between the 2nd U rib units；
Embedding benefit section, the embedding benefit section be embedded between the first U ribs unit and the 2nd U rib units and respectively with institute
State the first U ribs unit and the 2nd U rib element solders connection；
The embedding benefit section includes top connecting plate, the first side plate and the second side plate, the top connecting plate, the first side plate and
The length of second side plate is adapted with the first U ribs unit with the spacing between the 2nd U rib units, first side
Plate and second side plate are end to end with two side plates of the first U ribs unit and the 2nd U rib units respectively, described
Top connecting plate and the top plate of the first U ribs unit and the 2nd U rib units are end to end；
Wherein, first side plate and second side plate elder generation and the bottom plate and the first U ribs unit, described second
After U rib element solders are fixed, then by the top connecting plate be welded in the first U ribs unit and the 2nd U ribs 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 ribs
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 ribs all realizes welding by both sides
It connects, fatigue life is high, if embedding benefits section is single welding, is bound to cause U ribs embedding benefit section local fatigue service life low short slab.Cause
This, two sections of U ribs can be separately connected by above-mentioned technical proposal through the invention respectively by the first side plate and the second side plate
Come, internal and outer double can be implemented respectively and welded, is open when being equivalent to two side plates of welding, it is possible to freely real
Two-sided welding is applied, and since stress is smaller at the top of it, top blind flange can be after the completion of two plate-side plate weldings, from outside when welding
It is welded in place.
Based on the above technical solution, the present invention can also have following preferred technical solution.
Preferably, the U-shaped rib of the first U ribs unit and the 2nd U rib unit same sizes described in the embedding benefit Duan Weiyu,
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,
The top connecting plate and/or the first side plate and/or the second side plate and/or the first U ribs unit and/or the 2nd U ribs
Handle hole is opened up on unit.
Preferably, the handle hole is one or more, can be by the handle hole to implementing to weld inside the U-shaped rib
Connect or be arranged welding backing.
Preferably, in the inside of the U-shaped rib and with the angle seam crossing of the bottom plate and/or with the first U rib units
And/or the seam crossing of the 2nd U rib units is equipped with welding backing.
Preferably, the welding backing is ceramic backing or steel sleeve.
Preferably, at the abutment joint of the U-shaped rib and the first U ribs unit and the 2nd U rib units, and/or,
The angle seam crossing of the U-shaped rib and the bottom plate opens up welding groove.
Preferably, the handle hole is waist-shaped hole or circular hole or rectangular opening or other shapes of hole.
Preferably, in the inside of the U-shaped rib, reinforcing rib is circumferentially with along the handle hole.
Preferably, in the outside of the U-shaped rib, reinforcing rib is circumferentially with along the handle hole.
Preferably, in the outside of the U-shaped rib, the reinforcement cover board for covering the handle hole, the reinforcement are provided with
The shape of cover board is adapted with size with the handle hole.
Preferably, it is used between the embedding benefit section and the first U ribs unit, the 2nd U ribs unit and the bottom plate
Gas shield welding or manual welding connection.
In order to further clearly illustrate, the various aspects and advantage of embodiment disclosed by the invention will be in following description portions
The practice for becoming embodiment apparent or disclosed by the invention in point is recognized.

It enclosing, one circle reinforcing rib 7 of setting, the reinforcing rib 7 is set to the outside of top connecting plate 41, is welded to connect, and height can be 5-10mm,
Its inside edge is advisable apart from 44 periphery of handle hole for 5-20mm.
Embodiment 4
As shown in figure 5, on the basis of embodiment 2, reinforcing rib 7 is set to the inside of U-shaped rib, is equally set to handle hole 44
Around, height and thickness can be external identical with being set to, i.e., height can be 5-10mm, and inside edge is apart from handle hole 44
Periphery is advisable for 5-20mm.
Embodiment 5
As shown in fig. 6, on the basis of embodiment 2, in the outside of the U-shaped rib, it is provided with for covering the operation
The reinforcement cover board 8 in hole 44, the shape for reinforcing cover board 8 are adapted with size with the handle hole 44.The reinforcing plate and U-shaped rib
Connection type be welding or bolt.
In the above embodiments, the embedding benefit section 4 is used with the first U ribs unit 1 and the 2nd U ribs unit 2
Gas shield welding or manual welding connection.
In conclusion disclosed embodiment of this invention can have forms embedding benefit section in such a way that three blocks of plates splice,
Embedding benefit section can be formed with the mode of U-shaped rib, when with the scheme of U-shaped rib, in such a way that certain side opens up handle hole, all may be used
To realize what the embedding two-sided welding for mending section or the internal weld strength placed welding backing, and then reach embedding benefit section were met the requirements
Purpose.
