Description

A kind of U rib welding by both sides structure of putting more energy into of orthotropic stiffener
Technical field
The invention belongs to manufacture of steel structure field, be more particularly to the U rib welding by both sides of putting more energy into of a kind of orthotropic stiffener Structure, it is adaptable to science of bridge building and Shipping engineering.
Background technology
Orthotropic Steel Bridge Deck is as a kind of important feature form of the biggest or middle span steel bridge bridge deck, due to it There is, short construction period big, applied widely from heavy and light, ultimate bearing capacity and the feature such as deck-molding is little, handsome in appearance, receive each The favor of state Bridge Design person, its application has become one national Approach To Steel Bridge Designing of measurement and the mark of manufacture level.But, along with The increase of the increase of traffic flow, particularly heavy vehicle and overloaded vehicle, fatigue problem becomes increasingly conspicuous, and finding shows, The most a large amount of Orthotropic Steel Bridge Deck occur in that fatigue cracking problem within the operation phase the most to some extent.For landing warship The naval vessel of carrier aircraft, its deck uses similar orthotropic plate structure to there is fatigue endurance sex chromosome mosaicism too.
Due to the requirement to working place of the conventional steel structure welding technology, inside orthotropic deck system U rib and between top board Narrow space cannot welding, single welding outside U rib can only be used.T connector is equivalent to, outside U rib between top board and U rib one side wall Single welding causes existing inside non-welding natural breach, and at this, stress is concentrated and cannot be eliminated, and the weld seam centre of form and U rib one side floor There is bias in the centre of form, thus U rib side plate axial force certainly will counter plate and U rib side plate generation additional bending stress.
The present invention utilizes modern high end intellectual technology, welder device people is sent into inside U rib internal implementation U rib with top The welding of angle welding between plate, between U rib outside and top board, angle welding is completed by tradition automatic soldering technique, it is achieved thereby that orthogonal different Property Steel Bridge Deck U rib inside and outside twin fillet wolt weldering.Application claims U rib internal welding machine device people's system is provided simultaneously with welding, detects a flaw and lack Fall into the welding quality repairing three kinds of functions to ensure internal weld seams.Compared with traditional single welding, first U rib welding by both sides technology disappears Except the open gap (breach, stress concentrate) inside U rib and between top board, avoid outside single-sided welding time because of U rib root face Foozle and cause thoroughly weld defect, next adds section of weld joint and amasss, furthermore double weld seam centre of form is basic with the U rib floor centre of form Corresponding.Therefore use welding by both sides to improve the bonding strength between U rib and top board, significantly improve weld seam and weld seam position steel facing And the stress performance of U rib, it is particularly conducive to improve the resistance to of steel facing and its U intercostal welding position under local automobile, aircraft wheel load Fatigue behaviour.
Summary of the invention
It is an object of the invention to there are provided the U rib welding by both sides structure of putting more energy into of a kind of orthotropic stiffener, structure letter Single, it is convenient to implement, and improves the weld seam of orthotropic plate structure and weld seam position steel facing and the stress performance of U rib, improves Weld strength between U rib and top board, improves the resistance to of steel facing and its U intercostal welding position under local automobile, aircraft wheel load Fatigue behaviour.
In order to realize above-mentioned purpose, the present invention by the following technical solutions:
The U rib welding by both sides structure of putting more energy into of a kind of orthotropic stiffener, it is by steel facing, U rib of putting more energy into, the first angle welding (outward Side), the second angle welding (outside), the first angle welding (inner side), the second angle welding (inner side) composition, it is characterised in that: its U that puts more energy into The first angle welding (inner side), the connection of the first angle welding (outside) welding by both sides is used, its put more energy into U rib and steel between rib and steel facing The second angle welding (inner side), the connection of the second angle welding (outside) welding by both sides, more existing orthotropic U rib is used between panel Stiffened steel plates technology adds medial angle weld seam only with outside one-side-filled angle weld.
Described putting more energy between U rib and steel facing by the first angle welding, the second angle welding laterior horn weld seam is main stress Weld seam, described putting more energy into is welded for auxiliary stress by the first angle welding, the second angle welding medial angle weld seam between U rib and steel facing Seam.
Described putting more energy into must open slope by the first angle welding, the second angle welding laterior horn weld seam between U rib and steel facing Mouth is to meet the requirement of fusion penetration degree >=70%, and retains root face size >=1.5mm, fillet welding inside the first angle welding, the second angle welding Seam square groove, it is desirable to putting more energy into before welding the most closely connected between U rib 1 and steel facing 2, its gap requires≤1mm in principle.
Its steel facing of orthotropic stiffener and longitudinal and transverse ribbed stiffener all use the structural steel that solderability is good.Orthotropic adds Strength plate, it is put more energy into and uses the connected mode of medial and lateral welding by both sides between U rib and steel facing.In view of outer side weld welding and inspection It is convenient to survey, technology maturation, and outside welding seam design is main stress weld seam (>=70% penetration rate groove weld) by the present invention, and inner side is welded Seam is auxiliary stress weld seam;Outer side weld sets groove, root face size >=1.5mm, puts more energy into and to the greatest extent may be used between U rib and steel facing during welding Can be closely connected, its gap≤1mm, the two requires to be to ensure that the quality of weld joint on inner side;Put more energy into U rib height typically at 290- 310mm, wide 290-310mm suitable for reading, lower bottom width 170-190mm, U rib weld joint on inner side welding and detection narrow space, tradition hands Work and machine all cannot operate, and application claims U rib weld joint on inner side welding, detection and defect repair use miniaturization modern times intelligence Robot completes.
This is compared with prior art, has the following advantages and effect:
(1) increase U rib weld joint on inner side, eliminate the open gap inside U rib and between top board, on the one hand eliminate local stress Concentration effect, on the other hand when avoiding outside single-sided welding because of U rib root face foozle cause thoroughly weld defect.
(2) in the case of structure external applied load is identical, increase U rib weld joint on inner side, add total section of weld joint accordingly and amass, relatively Only section of weld joint stress during single welding significantly reduces.
(3) in the case of structure external applied load is identical, U rib weld joint on inner side is increased so that double weld seam centres of form and the one side of U rib The floor centre of form is the most corresponding, significantly reduces steel facing and the additional bending stress of U rib side plate at this.
(4) Theoretical Calculation and current test achievement show, the U rib of putting more energy into of steel construction orthotropic stiffener uses the present invention Welding by both sides connects more traditional single welding and connects, and the resistance to dynamic load of put more energy into U rib and steel facing connecting portion can improve fatigue life 1.0 again.
