Construction washer

Different types of washers are used in construction — for assembling timber houses from beams, erecting metal structures, building bridges. The range of applications is wide.

A construction washer differs from washers used in mechanical and machine-tool engineering: in linear dimensions, geometric shape, and material. The function remains the same — to increase the load-bearing area on the connected surfaces and prevent self-loosening of threaded fasteners. These two functions ensure the integrity of connected assemblies in service, including under systematic or sporadic vibration. In construction, washers also ensure joint strength under ground movement.

Building a low-rise timber or brick house with a hip or gable roof requires the use of washers. They are necessary for installing any roof other than a flat one. Elements of the rafter system are usually joined into a single assembly with large-diameter, long bolts. Such bolts are used with flat washers of increased hole diameter, as well as square and bevel washers. They are made of regular steels with subsequent anti-corrosion treatment.

Another type of washer is used when installing a metal frame. When positioned for operation, metal crossbars are joined with bolts and nuts, with square, bevel or rectangular washers placed under both ends of the fastener. The washers help precisely fix the elements relative to each other. As the metal heats up and expands, bevel washers create clearance for the movement of crossbars and beams, thereby preventing their deformation.
