Through pullout tests for shear resistance of the adhesive steel bar in the metal tube, the bond principals and failure modes of adhesives are studied.

The method of 5-ring screw hoop, 1-pen hoop and non-shrinkage high-strength mortar poured into sleeve is used at the seismic joint of new-type prefabricated reinforced concrete beam-column.

It applies the concrete anchoring of rolling straight thread sleeve-type anchor block, which makes construction convenient and anchoring reliable.
