Description
Technical field
The utility model belongs to manufacture of steel structure field, and the U rib of putting more energy into for being more particularly to a kind of orthotropic stiffener is double
Face welding structure, it is adaptable to science of bridge building and Shipping engineering.
Background technology
Orthotropic Steel Bridge Deck as a kind of important feature form of big or middle span steel bridge bridge deck at present, due to which
Have from heavy and light, ultimate bearing capacity be big, applied widely, short construction period and deck-molding little, handsome in appearance the features such as, receive each
The favor of state Bridge Design person, its application become the mark for weighing a national Approach To Steel Bridge Designing and manufacture level.However, with
The increase of the increase of the magnitude of traffic flow, particularly heavy vehicle and overloaded vehicle, fatigue problem become increasingly conspicuous, and finding shows,
A large amount of Orthotropic Steel Bridge Deck all occur in that fatigue cracking problem within the operation phase to some extent both at home and abroad.For landing warship
Similarly there is fatigue endurance sex chromosome mosaicism using similar orthotropic plate structure in the naval vessel of carrier aircraft, its deck.
Due to requirement of traditional welding for steel structure technology to operating space, on the inside of orthotropic deck system U rib and between top board
Narrow space cannot welding, can only be using single welding on the outside of U rib.Equivalent to T connector between top board and U rib one side wall, on the outside of U rib
Single welding causes the presence of natural breach on the inside of non-welding, and at this, stress concentration 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 utility model utilizes modern high end intellectual technology, welder device people is sent into inside U rib and is implemented on the inside of U rib
The welding of angle welding between top board, between U rib outside and top board, angle welding is completed by traditional automatic soldering technique, it is achieved thereby that just
Hand over twin fillet wolt connection inside and outside different in nature Steel Bridge Deck U rib.The utility model requires that U rib internal welding machine device people's system is provided simultaneously with weldering
Connect, detect a flaw and three kinds of functions of defect repair are to ensure the welding quality of internal weld seams.Compared with traditional single welding, U rib is two-sided
Welding technology eliminates open gap (breach, stress concentration) on the inside of U rib and between top board first, avoids outside single-sided welding
When the saturating weldering defect that causes because of U rib root face foozle, next increased section of weld joint product, furthermore double weld seam centres of form and U rib
The floor centre of form is corresponded to substantially.Therefore the bonding strength between U rib and top board is improve using welding by both sides, significantly improves weld seam and weldering
Seam position steel facing and the stress performance of U rib, are particularly conducive to improve steel facing and its U intercostal under local automobile, aircraft wheel load
The fatigue performance of welding position.
Content of the invention
The purpose of this utility model is the two-sided welding structure of U rib of putting more energy into that there are provided a kind of orthotropic stiffener, structure
Make simply, easy to implement, the weld seam of orthotropic plate structure and the stress performance of weld seam position steel facing and U rib is improved,
The weld strength between U rib and top board is improve, improves steel facing and its U intercostal welding position under local automobile, aircraft wheel load
Fatigue performance.
In order to realize above-mentioned purpose, the utility model is employed the following technical solutions：
A kind of two-sided welding structure of U rib of putting more energy into of orthotropic stiffener, it by steel facing, U rib of putting more energy into, outside angle welding,
Inner side angle welding composition, it is characterised in that：Which puts more energy into two-sided using inner side angle welding, outside angle welding between U rib and steel facing
The connection of weldering, its are put more energy into using inner side angle welding, the connection of outside angle welding welding by both sides between U rib and steel facing, more existing
Orthotropic U rib stiffened steel plates technology increased inner side angle welding only with outside one-side-filled angle weld.
Described outside angle welding between U rib and steel facing of putting more energy into is main stress weld seam, described put more energy into U rib and steel facing
Between inner side angle welding supplemented by help stress weld seam.
Described put more energy between U rib and steel facing outside angle welding must bevel to meet wanting for fusion penetration degree >=70%
Ask, and retain root face size >=1.5mm, inner side angle welding square groove, it is desirable to put more energy into before welding between U rib 1 and steel facing 2 to the greatest extent
May be closely connected, its gap requires≤1mm in principle.
Its steel facing of orthotropic stiffener and longitudinal and transverse ribbed stiffener are all using the structural steel that solderability is good.Orthotropic adds
Strength plate, its connected mode that puts more energy between U rib and steel facing using medial and lateral welding by both sides.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 utility model, interior
Side weld is auxiliary stress weld seam；Outer side weld sets groove, and root face size >=1.5mm is put more energy into during welding between U rib and steel facing
As closely connected as possible, its gap≤1mm, the two require to be to ensure that the quality of weld joint on inner side；U rib height of putting more energy into typically exists
290-310mm, width 290-310mm suitable for reading, lower bottom width 170-190mm, U rib weld joint on inner side welding and detection narrow space, pass
System craft and machine cannot all be operated, and the utility model requires U rib weld joint on inner side welding, detection and defect repair using miniaturization
Modern intelligent robot is completing.
This compared with prior art, with advantages below and effect：
(1) increase U rib weld joint on inner side, the open gap and between top board on the inside of U rib is eliminated, on the one hand eliminate local
Stress concentration effect, on the other hand avoids the saturating weldering defect caused during the single-sided welding of outside because of U rib root face foozle.
(2) in the case of structure external applied load identical, increase U rib weld joint on inner side, total section of weld joint product is accordingly increased, relatively
Only single welding when section of weld joint stress significantly reduce.
(3) in the case of structure external applied load identical, increase U rib weld joint on inner side so that the one side of double weld seam centres of form and U rib
The floor centre of form is corresponded to substantially, significantly reduces the additional bending stress of steel facing and 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 is using this practicality
The more traditional single welding connection of novel two-sided weldering connection, U rib of putting more energy into are permissible with the resistance to dynamic load fatigue life of steel facing connecting portion
Improve 1.0 times.
