Mechanical rebar connections, also known as mechanical splices or mechanical coupler, are used to join lengths of rebar together to transfer forces from one steel rebar to another. [1] [2] Rebar coupler. Mechanical couplers can be advantageous in comparison with conventional methods of lap splicing because of the requirement for less steel for ...
Mechanical couplers are an effective means to reduce rebar congestion in highly reinforced areas for cast-in-place concrete construction. These couplers are also used in precast concrete construction at the joints between members. The structural performance criteria for mechanical connections varies between countries, codes, and industries.
Dextra manufactures various brands of mechanical splices and anchorages, designed in accordance with the differing levels of performance criteria found throughout the world. The most common features of Dextra's Rolltec, Bartec, and Griptec splices are that they are all "parallel-threaded" systems.
A coupler connecting a crank and a slider in a single slider crank mechanism is often called a connecting rod, however, it has also been used to refer to any type of coupler. There are three basic types of planar four-bar linkage, depending on the use of revolute or prismatic joints:
A large number of Indian Standard (IS) codes are available that are meant for virtually every aspect of civil engineering one can think of. During one's professional life one normally uses only a handful of them depending on the nature of work they are involved in. Civil engineers engaged in construction activities of large projects usually have to refer to a good number of IS codes as such ...
The SA3 coupler is one of the strongest couplers in the world – maximum tonnage of a train that uses this type of coupler is about 8000 t [31] – but provides only mechanical coupling. [24] Adding automatic electrical and pneumatic connectivity is a complex challenge.
