Intemational Version AnconMBT Mechanically-Bolted Couplers for the Construction Industry

Reinforcing Bar Couplers Simplify the design and construction of concrete Lapped joints are not always an appropriate means of connecting reinforcing bars. The use of laps can be time consuming in terms of design and installation and can lead to greater congestion within the concrete because of the increased amount of rebar used. Ancon couplers can simplify the design and construction of reinforced concrete and reduce the amount of reinforcement required. affect the performance of the joint. The strength of a mechanical splice is independent of the concrete in which it is located and will...

The MBT range of couplers provides a cost-effective method of joining reinforcing bars, particularly when the fixed bar is already in place and there is insufficient space for a hydraulic swaging press. MBT Couplers are easy to install and achieve failure loads higher than 115% of the characteristic yield strength of grade 500 reinforcing bar. Neither bar end preparation to form threads, nor bar rotation are required. MBT couplers can also be used to join imperial, plain round or deformed reinforcing bars. The bar ends are supported within the coupler by two serrated saddles, and as the...

MBT Transition Series The MBT Transition series of couplers provides an effective solution for connecting bars of different diameters. Transition couplers have all of the benefits of the ET series and are designed to achieve failure loads higher than 115% of the characteristic yield strength of the smaller grade 500 reinforcing bar. They can be installed without any preparation to the bar ends and without any need to rotate bars. The coupler can be rotated to allow access to the bolts for tightening with either a ratchet wrench or a nut runner. In all cases heavy duty sockets should be...

Reinforcing Bar Couplers MBT Continuity C Series The MBT Continuity coupler allows reinforcement to be extended at construction joints without the need to drill or otherwise substantially deface the formwork. The female part of the C series coupler is fixed to the formwork with the aid of a nail plate. After removal of the formwork, the nail plate protects the internally threaded end of the coupler. It is advisable to loosen the nail plate to break the bond with the concrete whilst it is still ‘green’. When the nail plate is removed, the male section can be screwed into the existing section...

Repair and Remedial Work The MBT range of couplers is ideal for applications involving the replacement of corroded or damaged reinforcement as bar ends require no preparation or rotation. MBT ET Couplers When two MBT ET type couplers are used, the replacement bar is cut approximately 5mm shorter than the original length to allow clearance for insertion between the sound ends of the in-situ bars. MBT ET couplers are pushed fully over both ends of the replacement bar and temporarily held in position. The replacement bar is then correctly positioned and the couplers moved to a previously...

MBT Headed Anchors MBT Headed Anchors are designed to provide dead end embedment for bars in concrete. This helps to reduce congestion and simplify the placement of rebars by removing the need for hooked ends. The anchor comprises half an MBT coupler with a plate welded to one end which carries the full tension load of the bar when it is bearing against the concrete. Plates can be supplied with or without a hole, allowing bars to either end in or pass through the coupler. The MBT Headed Anchor also has the added advantage of requiring no special bar end preparation. Part No. (No hole in...

HM Grout Sleeve Couplers Ancon HM Grout Sleeves have been designed to cater for the rebar tolerance/bar alignment issues associated with joining precast concrete elements together. The range comprises two standard coupler types: Full-grout sleeves and Half-grout sleeves. In the first, bars are simply inserted to meet at the nominal centre point of the sleeve. In the latter, one end features a threaded insert to accept a pre-threaded bar while the other end is open to accommodate a non-threaded continuation bar. The standard insert suits Ancon Bartec Plus parallel-threaded rebars. Other...
