SPLICE SLEEVE FOR CONNECTING REINFORCING BARS TO ANOTHER ENTITY

摘要

A splice sleeve for connecting reinforcing bars in a concrete structure or the like to another entity with the sleeve being rigidly affixed to the reinforcing bar and provided with an anchor structure for anchoring the sleeve to another entity. In one embodiment, the sleeve is frustro-conical and provided with internal rings of equal height having an inner diameter which decreases toward the outer end. In another embodiment, the sleeve is cylindrical with internal rings of unequal height which have an inner diameter that decrease toward the end of the sleeve receiving the reinforcing bar. Hardenable grouting is used between the sleeve and reinforcing bar to positively lock the reinforcing bar, grouting and sleeve together thereby providing a rigid connection between the concrete structure in which the reinforcing bar is incorporated as well as the sleeve and associated anchor structure to another entity.
