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 ...
Lapping machine. Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine. Lapping often follows other subtractive processes with more aggressive material removal as a first step, such as milling and/or grinding. Lapping can take two forms.
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.
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:
Hybrid ring coupler in planar format. The hybrid ring coupler, also called the rat-race coupler, is a four-port 3 dB directional coupler consisting of a 3λ/2 ring of transmission line with four lines at the intervals shown in figure 12. Power input at port 1 splits and travels both ways round the ring.
A compression fitting 15 mm isolating valve. A compression fitting is a fitting used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. . In instances where two pipes made of dissimilar materials are to be joined (most commonly PVC and copper), the fittings will be made of one or more compatible materials appropriate for the connect
For hoses and piping, a quick connect fitting, also called a push fitting or Quick Connect Coupling, is a coupling used to provide a fast, make-or-break connection of gas or liquid transfer lines. Operated by hand, quick connect fittings replace threaded or flanged connections , which require wrenches.
Alternatively it is a short length of pipe with two female National pipe threads (NPT) (in North American terms, a coupler is a double female while a nipple is double male) or two male or female British standard pipe threads. If the two ends of a coupling are of different standards or joining methods, the coupling is called an adapter. Examples ...
