An expansion joint is designed to allow deflection in the axial (compressive), lateral (shear), or angular (bending) deflections. Expansion joints can be non-metallic or metallic (often called bellows type). Non-metallic can be a single ply of rubberized material or a composite made of multiple layers of heat and erosion resistant flexible ...
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.
Mageba (stylised as mageba) is a civil engineering service provider [1] and manufacturer of bridge bearings, expansion joints, seismic protection and structural monitoring devices for the construction industry. [2] The company is headquartered in Bulach, Switzerland, and operates through offices in Europe, Americas and Asia Pacific. [3]
The omission of the expansion joint removes a pathway for the penetration of chloride-bearing road salts to the bridge's sub-structure. In the United Kingdom there is a presumption that most new short to medium length bridges will be of the integral type. [citation needed] An early example of an integral bridge is masonry arch bridge.
[14] 115-millimetre (4.5 in) fixed-end slab seal type expansion joints were used for horizontal expansion of the joints. [14] Other essential components provided in the bridge structure are the handrails, lightning arresters, crash barriers, gas service support structures, telephone and electric lines, lifts in the pylons, and a maintenance gantry.
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.
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 ...
Application of Rubber Bridge Expansion Joints: Modular Bridge Expansion Joint is used in Highway bridge decks, Service ramps, Multi- storey car parks and so on. Modular Bridge Expansion Joint is used to prevent buildings or bridges appear some cracks because of climate change. Construction programs of Rubber Bridge Expansion Joints: (1) Set out ...
