Description

A kind of concrete pullout machine pin-connected panel anchoring piece
Technical field
The utility model is related to a kind of concrete pullout machine pin-connected panel anchoring pieces.
Background technology
Concrete pulling out method is exactly in maturing surface drilling, slot grinding, embedded anchoring piece and to install pullout machine progress Pulling out method detects, determination limit withdrawal force, and according to the phase between the limit withdrawal force and concrete crushing strength pre-established The detection method of pass relationship presumption concrete crushing strength.Wherein, anchoring quality is important a ring, the quality of anchoring quality, It is directly related to the precision and practicability of detection.Currently, concrete pullout machine conventional anchors are according to CECS 69-2011 《Pulling out method detects concrete strength technical regulation》Manufacture the swollen spring of production.By detecting practice for a long time, it is found that swollen spring exists such as Lower deficiency:(1) the ideal failure mode of concrete destroys for taper.Since several step stabilizer blades of swollen spring are separated, steps Concrete between stabilizer blade does not stress, and concrete annular groove upper surface is practical also subject to step branch other than bearing well-distributed pressure The local pressure that foot applies.When well-distributed pressure > local pressures, concrete taper is presented and destroys, experiment is normal;When uniformly distributed pressure When power < local pressures, it may appear that the phenomenon that concrete annular groove upper surface weak part first damages (i.e. office crushes bad) by pressure influences Accuracy of detection;(2) swollen spring shape is special, once damage, processing and fabricating is extremely complex, and the popularization to limit pulling out method makes With reducing practicability;(3) after the test, swollen spring is removed, needs first to gather the step stabilizer blade of swollen spring with pipe collar, then It pulls out.After concrete destruction, hole often deforms, if deformation is excessive, the tiptoe and hole sidewalls of step stabilizer blade Friction could even pull out concrete destruction with prodigious power, reduce detection practicability.
In conclusion the swollen spring of conventional anchors is since there are above-mentioned shortcoming, one side office crushes bad influence detection Precision;Another aspect processing and fabricating is complicated, swollen spring pull-out is difficult, reduces practicability.Therefore it needs to be improved.
