Ascon Engineering Systems

ASCON MECHANICAL SPLICING The traditional and the most accepted form of Rebar splicing is the conventional system of lapping of the Rebars. Over the past few decades, the mechanical splicing systems were developed so as to ease congestion of Rebars and to assist in specialized construction arising due to complex designs and advanced form work systems. The increased complexities in design, advanced modern construction techniques, demand for increased speed of construction, and the ever rising steel prices have made the threaded mechanical splicing system the right choice for the construction industry ASCON TAPER THREADED RE-BAR COUPLER The ASCON Tapered Thread coupler is designed to suit majority of applications which require the splicing of reinforcement bars. The ends of the rebar are square cut with a chop saw machine and a tapered thread is made on the bar to suit the taper threaded coupler. The sleeve is tightened onto the threaded bar end using a wrench and then finally checked with a calibrated torque wrench. ASCON STANDARD COUPLER The ASCON Standard Tapered Thread coupler is suitable for connecting two bars of the same diameter, where one bar can be rotated. It consists of an internally threaded coupler with two right hand threads which are tapered towards the middle of the coupler. The bar ends are square cut and a tapered thread is cut onto the bar. The couplers are generally fitted on the reinforcing bar in the bar threading shop and the internal threads of the coupler are protected by plastic end caps. The threaded end of the rebar is protected by plastic thread protectors known as bar caps. Engagement of the bar within the coupler is simplified by the tapered thread design which aids alignment. The Ascon Standard Tapered Thread coupler is designed to meet the requirements of BS 8110 and to achieve failure loads in excess of 115% of the characteristic strength of grade Fe 415 & Fe 500 TMT rebar.
