Specific embodiment
Below in conjunction with drawings and examples, the technical solution of the utility model is described in detail.
U rib 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 horizontal direction in the sliding slot in detection 1 middle position of body, auxiliary
Slide rule 3 is helped to be mounted in the sliding slot of detection 1 top position of body in the horizontal direction；Measuring point slide rule 2 is parallel with auxiliary slide rule 3 to be laid,
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 carry out 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.
A kind of U rib and roof and floor Size of welds size and detection method, will test 1 bottom of body and are aligned with top plate or bottom plate
Arrangement；Measuring point slide rule 2 and U rib is positioned opposite, by the length and the guarantor that slide vertically the adjustment of bar 6 detection body 1 and roof and floor side
It is fixed to keep steady；Assist position of the slide rule 3 to auxiliary positioning U rib measuring point；It auxiliary slide rule 3 and slides vertically bar 6 and can guarantee 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 rib is H；The angle [alpha] of U rib；
The realization process of this method is as follows：1), when detecting Size of welds K1, due to U rib 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 determining K1 value；
It is opposite, after giving K1 value, by being scaled detected value to get to the reading of measuring point slide rule 2 when detecting.
2), Δ value determines：It is calculated according to contact height H Δ=H/tan α of the angle [alpha] of U rib and sliding ruler, live institute
With the height H=30mm of leg ruler sliding ruler, bottom plate U rib angle [alpha]=74 degree, then Δ=9mm；Top plate U rib angle [alpha]=77 degree,
Then Δ=7mm.
3), K1 recommendation：Design requirement U rib is groove weld, and depth of penetration 80% has no leg requirement, technique groove
It dehisces for 1mm root face, 55 degree.To guarantee 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 thickness 6mm, K1 take 4~5mm；Top plate U rib thickness 8mm,
K1 takes 5~6mm.
4) reading when, detecting is K1+ Δ：Bottom plate K1+ Δ=(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, control when the above parameter and calculated result are listed in the table below for detection：Certain bridge bridge top, bottom board unit
U rib Size of welds K1 detects table.
Size of welds K2 (reference that K2 numerical value is only used as U rib Size of welds size) detection table K2 can dehisce size by groove
Big 1~2mm, based on 55 degree of groove subtended angle, bottom plate U rib is dehisced for 6mm, then K2 can use 7~8mm；Top plate U dehisces for 8mm, then
K2 can use 9~10mm.Control when listing K2 detection table accordingly for detection：
Note：K1 detection schematic diagram is contrasted when detection, fixed ruler side need only be come on U rib.Pass through this measurement inspection party
Method, so that it may which quantization inspection is carried out to the Size of welds size of U rib plate unit.
