Specific implementation mode
Below in conjunction with drawings and examples, technical scheme of the present invention is described in detail.
U ribs and roof and floor Size of welds size and detection device, the device include detection body 1, measuring point slide rule 2, auxiliary cunning
Ruler 3, auxiliary moving ball 5, slides vertically bar 6 and positioning metering plate 7 at measuring point moving ball 4；Detection body 1 is irregular shape, detection
The upper and lower part of body 1 is horizontal structure, and measuring point slide rule 2 is mounted in the sliding slot in 1 centre position of detection body in the horizontal direction, auxiliary
Slide rule 3 is helped to be mounted in the sliding slot of detection 1 top position of body in the horizontal direction；The laying parallel with auxiliary slide rule 3 of measuring point slide rule 2,
Measuring point moving ball 4 is fixed on measuring point slide rule 2, and auxiliary moving ball 5 is fixed on auxiliary slide rule 3；The setting of bar 6 is slid vertically to examine
Survey body 1 bottom and can along detection body 1 vertical progress vertical sliding；Position metering plate 7 setting measuring point slide rule 2 with it is to be checked
It surveys on the detection body 1 between part.
The bottom of the lower part of slide rule 3, the lower part of measuring point slide rule 2 and detection body 1 is assisted to be equipped with graduated scale.
The corner for detecting 1 side of body is equipped with oblique chamfering.
1 bottom of detection body is aligned by a kind of U ribs and roof and floor Size of welds size and detection method with top plate or bottom plate
Arrangement；Measuring point slide rule 2 and U ribs are positioned opposite, by sliding vertically length and guarantor of the adjustment detection body 1 of bar 6 with roof and floor side
It is fixed to keep steady；Assist slide rule 3 to the position of auxiliary positioning U rib measuring points；It auxiliary slide rule 3 and slides vertically bar 6 and can ensure transverse direction
With vertical positioning stablity, accurately.
If detection Size of welds is K1, the contact height of measuring point slide rule 2 and U ribs is H；The angle [alpha] of U ribs；
The realization process of this method is as follows：1), when detecting Size of welds K1, due to U ribs angle [alpha] and contact height H
It influences, the increment Δ that kept the practical Size of welds K1 of read-around ratio more, as long as determining Δ value, it will be able to indirectly determine K1 values；
It is opposite, after giving K1 values, by being scaled detected value to get to the reading of measuring point slide rule 2 when detection.
2), Δ value determines：It is calculated according to the contact height H of the angle [alpha] of U ribs and sliding ruler Δ=H/tan α, live institute
The height H=30mm of ruler, bottom plate U ribs angle [alpha]=74 degree, then Δ=9mm are slided with leg ruler；Top plate U ribs angle [alpha]=77 degree,
Then Δ=7mm.
3), K1 recommendations：Design requirement U ribs are groove weld, and depth of penetration 80% has no leg requirement, technique groove
It dehisces for 1mm root faces, 55 degree.To ensure depth of penetration and weld seam and the even suitable transition of member section, it is considered as accommodation Welding
It is practical, on the basis of groove welding is flat from a small leg, bottom plate U rib thicknesses 6mm, K1 take 4~5mm；Top plate U rib thickness 8mm,
K1 takes 5~6mm.
4) reading when, detecting is K1+ Δs：Bottom plate K1+ Δs=(4~5)+9=13~14mm, Δ=(5 top plate K1+
~6)+7=12~13mm.When actual measurement reading is more than the range of bottom plate and top plate, that is, meet the recommendation of K1.
For convenience of detection, the above parameter and result of calculation are listed in the table below for being compareed when detection：Certain bridge bridge top, bottom board unit
U rib Size of welds K1 detects table.
Size of welds K2 (reference of the K2 numerical value only as U rib Size of welds sizes) detection table K2 can dehisce size by groove
Big 1~2mm, based on 55 degree of groove subtended angle, bottom plate U ribs are dehisced for 6mm, then K2 can use 7~8mm；Top plate U dehisces for 8mm, then
K2 can use 9~10mm.K2 detections table is listed accordingly for being compareed when detection：
Note：K1 detects schematic diagrams are contrasted when detection, fixed ruler side need only be come on U ribs.Pass through this measurement inspection party
Method, so that it may which quantization inspection is carried out with the Size of welds size to U rib plate unit.
