Abstract
The utility model relates to a test block for detecting a U rib of a steel box girder. The test block comprises a panel (1) and a U rib plate (2), wherein the panel (1) and the U rib plate (2) are welded together with an included angle of 60-80 degrees, and a fillet seam (3) is formed; a short transverse hole (4) which is a blind hole is formed in the fillet seam (3). According to the test block for detecting the U rib of the steel box girder, the difficulty that no comparison test block is available for detecting the fillet seam of the U rib of the steel box girder is fundamentally solved; the test block is welded by a technology which is consistent with the design technology of the steel box girder; the test block is simple in design, easy to operate and convenient to use.
Description
Technical field
The present invention relates to a kind of bridge steel box girder U angle of rib welding line ultrasonic phased array detection reference block, belong to technical field of nondestructive testing.
Background technology
Bridge steel box girder U angle of rib weld seam is a kind of lack of penetration fillet weld, general designing requirement weld seam depth of penetration be the U floor thick 80%.When carrying out weld penetration and Inner Defect Testing, choosing of its sensitivity will be with certain type of reflecting body with size in test block, reach the height benchmark as a comparison of appointment with its reflecting body echo height in designated depth, test block simultaneously can be used for demarcating detection range and pass judgment on defect size.In detecting for the U ribs of steel box girder fillet weld at present, there is no the detection test block of response, can't guarantee like this sensitivity that ultrasonic phase array detects, the detection quality that the while also can't the U ribs of steel box girder weld seam.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of energy to be used for the reference block that the U ribs of steel box girder fillet weld detects use, has solved the U ribs of steel box girder fillet weld and has detected without a reference block difficult problem.
The purpose of this utility model is achieved in that
A kind of U ribs of steel box girder detects and use test block, and be characterized in: described test block comprises panel and U floor, and described panel and U floor are 60 ° ~ 80 ° angles and weld together, and the formation fillet weld, has the hyphen hole on described fillet weld, and described hyphen hole is a blind hole.
A kind of U ribs of steel box girder of the utility model detects uses test block, and 50 ° of grooves are opened in the plate end of its U floor, and stay the 1mm root face, stay the 0.5mm fit-up gap between panel and U floor.
A kind of U ribs of steel box girder of the utility model detects uses test block, its U floor width 20～30mm, and thickness is 8mm, and length is 70～90mm, and panel width is 20～30mm, and thickness is 20mm, length is 15～30mm.
Compared with prior art, the beneficial effects of the utility model are:
A kind of U ribs of steel box girder of the utility model detects uses test block, has fundamentally solved the U ribs of steel box girder fillet weld and has detected without a reference block difficult problem, adopt the technique welding consistent with the design of steel case beam to complete, and design operation is simple, easy to use.

Embodiment
Referring to Fig. 1-3, the utility model relates to a kind of U ribs of steel box girder detection test block, one group three of described test blocks, each test block comprises panel 1 and U floor 2, described panel 1 and U floor 2 are 78 ° of angles and weld together, and form fillet weld 3, and open respectively diameter on the fillet weld 3 of described three test blocks and be the hyphen hole 4 of 0.5mm, 1mm and 2mm, the length in described hyphen hole 4 is 10mm.
Wherein panel 1 width is 20～30mm, length 15～30mm, U floor 2 width 20～30mm, length 70～90mm, 50 ° of grooves are opened in the plate end of U floor 2, and stay the 1mm root face, stay the 0.5mm fit-up gap between panel 1 and U floor 2, then at a certain angle U floor 2 and panel 1 are welded together, welding penetration is 80% of U floor 2 thickness.
Operating process: according to the requirement that detects of U ribs of steel box girder fillet weld, respectively in three test blocks of a group, the ultrasonic phase array probe is placed on the obtuse angle side of U floor 2, direction mobile probe perpendicular to fillet weld 3, hyphen hole 4 in test block is shown on screen clearly, the echo amplitude of adjusting hyphen hole 4 is determined the detection sensitivity of ultrasonic phase array to all over the screen 60%～80%, can utilize end-point method to measure length simultaneously.Instrument can detect on entity after adjusting.
