A expansion joint, or movement joint, is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials. They are commonly found between sections of buildings , bridges , sidewalks , railway tracks , piping systems , ships , and other structures.
Expansion joints for industrial applications Technical information 1930 Expansion joints 1930. ... Always at least two angular expansion joints are needed.
A breather switch, expansion joint, or adjustment switch is an intentional gap in railway tracks to allow for thermal expansion in long sections of otherwise unbroken rail. . They are placed between very long sections of continuous welded rail or at the transition from continuous welded rail to jointed track, and commonly in the vicinity of bridges, viaducts and tunnels where the ...
A hinged expansion joint is a metallic assembly, that can rotate in a single plane, used to absorb changes resulting from piping thermal expansion or contraction. [ 1 ] Hinged Expansion Joint - U.S. Bellows, Inc.
fabric joints cost $100 to $200 per square foot of joint (2010). Metal joints can cost twice this amount. fabric expansion duct forces are assumed to be 0 #/inch. Metal expansion joint forces for metal joints a 24-inch diameter duct are on the order of 850#/ inch of movement for axial spring rate, and 32,500 #/inch for lateral movement.
Possible causes of movement are thermal expansion and contraction, creep, shrinkage, or fatigue due to the properties of the material used for the bearing. External sources of movement include the settlement of the ground below, thermal expansion , and seismic activity . [ 1 ]
