The tensile test of steel bar is the field test of the anchoring force. After 48-72 hours of rebar planting, the tension meter (Jack) can be used to carry out the drawing test of the reinforced bar.
The tensile test of steel bar is the field test of the anchoring force. After 48-72 hours of post installed anchoring, the tension meter (Jack) can be used to carry out the drawing test of the reinforced bar.
Experimental steps
1. In general, 72 hours after planting steel bar, the pulling force test of the steel bar can be carried out by the force meter (Jack). In order to reduce the confinement of the jack to the concrete near the anchor bar, it is installed under the channel steel or scaffold. The fulcrum distance is more than max (3D, 60mm). Then uniform loading for 2 to 3 minutes (or step loading) until failure.
Failure modes are divided into
The structural member’s failure mode should be controlled by steel bar breaking.
2.For non-destructive testing, the maximum loading value is 0.95Asfyk.
3.The quantity of sampling can be determined by 0.1% of the amount of planted bars, but not less than 3.
4.The following two loading systems can be used for anchor bolt pull test: continuous loading, loading at constant speed to setting load or anchoring failure, and the total loading time is 2min~3min.
You can find anything here you are in need of, have a trust trying on these products, you will find the big difference after that.
