Control joints are used in masonry, concrete, and plasterboard structures to limit damage caused by natural shifts and movements. They guide excessive tension to intended locations, facilitating repair of damage. Three techniques are used to add control joints to concrete structures. Control joints are also used to control cracks in drywall partitions. Control joints are […]
Pipe couplings are essential for plumbing systems and come in three categories: flared and sweaty joints for copper pipes, ball and mechanical joints for cast iron pipes, and five types for plastic pipes. Other types include glass piping and coated metal piping joints. A pipe coupling is a key component to any successful plumbing system […]
Welded joints fuse two metal pieces together using a soldering iron. There are two types of welding: liquid-state and solid-state fusion. Welding has many advantages over traditional joints, including strength, aesthetic appeal, and repairability. Welders wear protective gear and require years of practice to master. Liquid fusion welding involves melting a third element to fuse […]
This text explains different types of solder joints used to join metal pieces together, including butt, angle, edge, lap, and T-joints. Each joint has different strengths and uses, and the variation used depends on the thickness of the metal and the required strength of the joint. A solder joint is used to join two pieces […]
Rigid couplings join two shafts in a motor or mechanical system, improving performance and increasing machine life. Sleeve, clamp, and flanged designs are available in different materials and sizes. Rigid couplings are more effective than flexible ones for precise alignment and a secure fit. A rigid coupling is a unit of hardware used to join […]
Different wood joints are suitable for different objects. The mortise and tenon is the strongest joint, while dowel, spline, biscuit, dovetail, finger, dado, rebate, and butt joints are also effective. Choosing the most effective wood joint generally depends on the type of object a craftsman is building. For example, wood joints that would serve perfectly […]
Drywall is a popular alternative to plastered walls in homes built after the 1940s. It is made by sandwiching plaster slurry between two sheets of paper and is fixed to wooden supports using nails or screws. Drywall joints are covered with tape and jointing compound for a smooth finish. Fiberglass mesh tape is a newer […]
Expansion joints allow for expansion and contraction in construction due to weather changes. They are used in bridges, sidewalks, railroad tracks, and piping systems to minimize maintenance expenses and ensure functionality. Including expansion joints in building and plumbing systems reduces pressure and cracking, making them cost-effective. Expansion joints are devices that are used to allow […]
Masonry joints are created with wet mortar to fasten brick or concrete materials in building construction. Tuck pointing is the process of replacing old grout. There are four types of masonry joints: concave, V-shaped, weathered, and flush. Masonry joints must be applied correctly to prevent erosion and damage to the property. Masonry joints are used […]
Joints in the body, such as knuckles, spine, knees, and hips, can make a clicking sound when moved. Some believe it’s caused by a change in joint fluid pressure, while others suggest it’s due to the movement of muscles or tendons. Intentionally cracking joints does not appear to cause long-term joint problems, and there is […]
Joint strengthening involves improving mobility and combating degenerative conditions like arthritis. Strengthening muscles and ligaments surrounding joints is key, along with resistance training and a healthy diet. Beginners should consult a professional trainer. Joints are made up of various types of soft tissue and bone. Joint strengthening involves improving joint strength and mobility and combating […]
