发明名称 Bar coupling apparatus and methods
摘要 Particular embodiments of the inventive technology relate to a device for connecting the ends of two concrete reinforcing bars in which a metal sleeve has chambers at each end to accommodate the end of one reinforcing bar. Forces may be transferred from one bar to the other through, the use of, inter alia, an adhesive established within the space between the outside of the reinforcing bars and the deformed inner surface of the sleeve. The chambers are, preferably, separated by a fluid impervious barrier. One port associated with each chamber may be established to allow fluid such as air to escape, preventing air voids in the adhesive. Another configuration of the inventive device would be intended for the retention (under load, of course) of only one reinforcing bar, with an enlarged flange for anchoring the end of one reinforcing bar, perhaps at and outer surface of, e.g., a concrete slab.
