General Information HRC Group Machinery. The HRC group is the largest owner of specialized friction welding machinery for production of reinforcement products in the world. This machinery is stored at different sites in several countries and can be set-up at customers
Apr 29, 2008 · Splicing Irons/Kits enable in-field expansion joint repair. Friction / Fusion Welders Ultrasonic Welding System splices flexible flat cable. Fasteners & Hardware In-Situ Rebar Splice meets Ultimate Splice requirements. Machinery & Machining Tools Ultrasonic Splicer has modular design. Machinery & Machining Tools Mechanical Splices of Reinforcing BarsConcrete Therefore proper splicing of rebars becomes essential to the integrity of reinforced concrete. There are three basic ways to splice bars:lap splices, mechanical connections, and welded splices. Of the three, lap splicing is the most common and usually the least expensive. If lap splices are impossible or impractical, the engineer will choose Other Construction Equipment & Tools, Construction Rebar Splice with Friction Weld Features:1. Rebar and thread rod are connected by friction weld, and then connected with coupler. 2. High precision, high production
Sep 22, 2017 · However, if the carbon equivalency (C.E.) for A615 steel is calculated to be .55% or less for rebar sizes up to #6, and less than .45% for bars larger than #7, the rebar can be welded with no preheating. This specification is found in American Welding Society D1.4/D1.4M, Structural Welding Code-Reinforcing Steel. Rebar Coupler for Connection System - ADTO MallA mechanical rebar splice is a joint or a coupler used to splice two rebars. Mechanical rebar splicing is a new type of splicing in the world construction industry. The mechanical rebar splice has many advantages compared to the conventional method of overlapping. A longer reinforcement bar is obtained through this rebar coupler splicing. The errors due to wrong lap length as in the conventional Rebar Coupler for Connection System - ADTO MallA mechanical rebar splice is a joint or a coupler used to splice two rebars.

A quick-connect splice joint for concrete reinforcement bars. Two diametrically opposed semi-cylindrical shells span the adjacent bar ends. The two shells are held against axial displacement by mating to raised features such as ridges or threads on the bars, and are held radially by an outer sleeve. The splice is axially preloaded by nuts threaded on the bars. US6089779A - Quick connect rebar splice - Google PatentsA quick connect splice for concrete reinforcement bars includes two diametrically opposed half-shells spanning the aligned ends of the rebars. The half-shells interlock with raised ridges on the bar surfaces to hold the bar ends together. Two sleeve elements slipped over the bars are screwed to each other over the shell sections to secure the splice joint. V-Belts BEHAbeltWelding the belt profile. The heat generated by friction in the friction welding machine splices the belt in seconds. When using welding paddles, 290°C is required for PU belts and 240°C for TPE belts. The BEHAbelt welding machines (e.g. EErgo) ensure a constant welding temperature even at different ambient temperatures.
nVent LENTON weldable couplers provide a quick and easy solution for connecting reinforcing steel bar (rebar) to structural steel sections or plates. The coupler is internally taper threaded on one end with the other end or exterior surface prepared for welding. C2/C3J Weldable Half-Coupler C2/C3J Weldable Half-Coupler for Nuclear Applications Weldable Rebar Coupler Products & Suppliers How to Select Rebar Supports and Spacers Rebar supports and spacers are used to secure the reinforcing steel or rebar in UK, first ever friction welded coupler . bars and couplers Install and stress post-tensioning bars Install top positioning fixtures Place and weld rebar splices and ties in vertical joints Inject grout Welding Rebar - Structural engineering general discussion Jun 15, 2007 · A615 is not "good" enough for welding and may have cracking problems at the welds. If you cannot get a mechanical splice in there I don't know what else you can really do. I would have the contractor chip back far enough to get the mechanical splice in, and probably far enough to stagger the splices so you will have some more room.
Ultimate products are attached to the reinforcing steel using friction forging technology (commonly called friction welding). Each friction welder is manufactured with state-of-the-art control systems and quality monitoring to ensure every connection is produced as intended. The product design and optimized friction welding parameters maximize the performance of the rebar connections with multiple types and grades of rebar.
