  2. Expansion joint - Wikipedia

    en.wikipedia.org/wiki/Expansion_joint

    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.

  3. Pin and hanger assembly - Wikipedia

    en.wikipedia.org/wiki/Pin_and_hanger_assembly

    Pin and hanger assembly. A pin and hanger assembly is used to connect two plate girders of a bridge.These assemblies are used to provide an expansion joint in the bridge. One beam (the anchor span) is set on a pier with a short section cantilevered out toward the next pier.

  4. Mortise and tenon - Wikipedia

    en.wikipedia.org/wiki/Mortise_and_tenon

    Mortise and tenon joints are strong and stable joints that can be used in many projects. They connect by either gluing or friction-fitting into place. The mortise and tenon joint also gives an attractive look. One drawback to this joint is the difficulty in making it because of the precise measuring and tight cutting required.

  5. Expansion Joint Manufacturers Association - Wikipedia

    en.wikipedia.org/wiki/Expansion_Joint...

    The standards are a combination of a variety of expansion joint manufacturers' knowledge and experience. [2] [3] The EJMA organization performs extensive technical research on a variety of topics concerning the design and manufacturing of expansion joints. [4] This knowledge contributes to providing new versions of the EJMA book of standards.

  6. Hinged expansion joint - Wikipedia

    en.wikipedia.org/wiki/Hinged_expansion_joint

    The expansion joint hinges provide for angular movement and will resist pressure thrust forces. [4] Individual hinged expansion joints used in piping systems are restricted to pure angular rotation by its hinges. As a pair, hinged expansion joints will function together to absorb lateral deflection.

  7. Metal expansion joint - Wikipedia

    en.wikipedia.org/wiki/Metal_expansion_joint

    They are differentiated according to the three basic types of movement: axial, angular and lateral expansion joints. Expansion joints have usage in various sectors, like energy production, paper industry, chemical industry, water treatment, oil and gas. Expansion joints can be used wherever thermal movements or vibration occurs in pipelines.

  8. Toroidal expansion joint - Wikipedia

    en.wikipedia.org/wiki/Toroidal_expansion_joint

    Toroidal Expansion Joint - U.S. Bellows, Inc. A Toroidal expansion joint is a metallic assembly that consists of a series of toroidal convolutions which are circular tubes wrapped around pipe ends or weld ends and have a gap at the inside diameter to allow for axial stroke while absorbing changes in expansion or contraction of the pipe line. [1]

  9. Slip joint - Wikipedia

    en.wikipedia.org/wiki/Slip_joint

    Slip joints are common under conditions where temperature changes can cause expansion and contraction that may overstress a structure. These are generally referred to as expansion joints . Bridges and overpasses frequently have sliding joints that allow a deck to move relative to piers or abutments.
