Description
Technical field
The utility model provides a kind of presstressed reinforcing steel-ground tackle assembly static test locating device, belongs to ground tackle static test detection technique field.
Background technology
When carrying out presstressed reinforcing steel-ground tackle assembly static test and detecting, representational some presstressed reinforcing steels should be chosen according to standard-required, according to first 4 grades of load application, measure the relative displacement Δ a between itself and ground tackle step by step.Δ a should with the proportional change of stressed increment of presstressed reinforcing steel, as disproportionate change, should check presstressed reinforcing steel whether lose anchor slide.After being installed by presstressed reinforcing steel-ground tackle assembly, need the mark that fixes on presstressed reinforcing steel, be convenient to measure relative displacement Δ a.Because presstressed reinforcing steel tensile strength is higher, be difficult to, when not destroying the material of presstressed reinforcing steel own, carry out clear marking on its surface.Therefore needing a kind of locating device, ensureing to carry out clear marking when not destroying the material of presstressed reinforcing steel own, can ensure that the reference point that every grade of load action bottom offset is measured is consistent, improve measuring accuracy.
Summary of the invention
The utility model provides a kind of presstressed reinforcing steel-ground tackle assembly static test locating device, clear marking can be carried out when not destroying the material of presstressed reinforcing steel own by this device, can ensure that the reference point that every grade of load action bottom offset is measured is consistent, improve measuring accuracy.This device is simple to operation, improves work efficiency.
The technical scheme that the utility model adopts is:
Presstressed reinforcing steel-ground tackle assembly static test locating device, comprise clip, screw rod, nut, a parallel hole is respectively offered in both sides, described clip lower end, screw rod is connected with nut through parallel hole, clip is used for fixing presstressed reinforcing steel, the top of clip is provided with location-plate, and intersection, location-plate diagonal angle is set as central point, and described central point is as the reference point of displacement measurement.
Described location-plate is square plank, and its intersection, diagonal angle sets a cross searching point, and indentation is on location-plate.
Described clip is ring stainless steel hoop.
Utilizing the utility model presstressed reinforcing steel-ground tackle assembly static test locating device, clear marking can be carried out when not destroying the material of presstressed reinforcing steel own, can ensure that the reference point that every grade of load action bottom offset is measured is consistent, improve measuring accuracy.This device is simple to operation, improves work efficiency.

Wherein: 1-clip, 2-screw rod, 3-nut, 4-location-plate, 5-presstressed reinforcing steel, 6-height gauge, 7-ground tackle, 8-anchor slab, 9-intermediate plate, 10-reference point.
Embodiment
As shown in Fig. 1 ~ Fig. 3, presstressed reinforcing steel-ground tackle assembly static test locating device, comprises clip 1, screw rod 2, nut 3, guarantees that this device possesses enough bearing capacities and installation and removal are convenient.Clip 1 adopts the manufacture of ring stainless steel material, and thickness ultrathin, pliability are strong.A parallel hole is respectively offered in both sides, described clip 1 lower end, screw rod 2 is connected with nut 3 through parallel hole, and clip 1, for fixing presstressed reinforcing steel 5, is fixedly welded with location-plate 4 on the top of clip 1, intersection, location-plate 4 diagonal angle is set as central point, and described central point is as the reference point 10 of displacement measurement.
Preferably, location-plate 4 is square plank, and its intersection, diagonal angle sets a cross searching point, and indentation, on location-plate 4, ensures that mark is clear and reference point 10 is fixing.
During use, first process the floating rust in presstressed reinforcing steel 5 surface and greasy dirt, make it clean clean.Again presstressed reinforcing steel 5 is passed ground tackle Machine in Static Load Test, the intermediate plate 9 of corresponding ground tackle 7 and correspondence is installed.Then add initial stress at stretching end to presstressed reinforcing steel 5 with little lifting jack, be added to 10% of presstressed reinforcing steel 5 tensile strength standard value, the initial stress of every root presstressed reinforcing steel 5 all wants evenly consistent, and now presstressed reinforcing steel 5 is locked.
According to standard-required, choose representational some presstressed reinforcing steels, by the utility model presstressed reinforcing steel-ground tackle assembly static test locating device, be enclosed within presstressed reinforcing steel 5, tightening nut 3, ensure this device and presstressed reinforcing steel 5 reliably fastening.Now presstressed reinforcing steel-ground tackle assembly installs.Height gauge 6 is adopted to measure its displacement between ground tackle 7.Height gauge 6 base is close to anchor slab 8 surface, mobile slide calliper rule, until the reference point 10 of measurement, read displacement measurement.Then measure its displacement between ground tackle 7 step by step, calculate relative displacement Δ a.
