In order to achieve pull-through of transverse rebar of one-way precast slab to form two-way slab without wet operation or welding, considering the operability and efficiency of construction, steel plate composite blind bolts as rebar mechanical connectors were proposed. To study the tensile properties of the connectors, a monotonic tensile test was performed on 22 specimens. The research parameters were steel plate strength, number of bolts, pre-tightening force, and anchorage length, and the failure form, ultimate bearing capacity, load-displacement curve, and deformation capacity were investigated. Research results show that there were two failure modes of the specimens including fracture and pull-out of rebar. For the quenched and tempered 45＃ steel cover plate, the critical anchorage length of the reinforcing bar of the connector was between 2d and 3d. When it was less than the critical anchorage length, the rebar experienced scraping plough type pull-out; when it was larger than the critical anchorage length, the rebar would fracture. When the number of the connecting bolts was four, the specimens realized equal-strength connection of rebars. With the decrease in the width of the connecting cover, the critical anchorage length increased. Under the same anchorage length, the tensile strength of the joints increased with the increase in the pre-tightening force of the bolts. For the Q460C high-strength steel cover plate, the failure modes were deformation of the tooth nails and pull-out of the rebar. Under the same experimental conditions, the failure modes of the specimens with ribbed bars and rounded steel bars were the same. The formula for calculating the tensile bearing capacity of the proposed connector was proposed, and the analytical values agreed well with the experimental results, which could provide references for relevant design and research.
