| Expansion joint or movement joint is an assembly designed to safely absorb the heat-induced expansion and contraction of construction materials, to absorb vibration, to hold parts together, or to allow movement due to ground settlement or earthquakes. |
| (1)Bridge expansion joint A.Bridge expansion joints are designed to allow for continuous traffic between structures while accommodating movement, shrinkage, and temperature variations on reinforced and prestressed concrete, composite, and steel structures.There are various types, which can accommodate movement from 30 to 500 millimeters . B.Modular expansion joints are used when the movements of a bridge exceed the capacity of a single gap joint or a finger type joint. They can be used for longitudinal movements of as little as 160 mm, or for very large movements of well over 3000 mm. |
| (2)Railway expansion joint If a railway track runs over a bridge which has expansion joints that move more than a few millimeters, the track must be able to compensate this longer expansion or contraction. Such an expansion joint looks somewhat like the tongue of a railroad switch,but it has a completely different purpose and operation. |
| (1)Steel expansion joint Stainless steel bridge expansion joints separates the structural elements above the basic, and sets apart appropriate gap between both sides in order to ensure the structural elements on both sides of stainless steel bridge expansion joints free flexible in horizontal direction. The wide of sew is always 20-40mm. |
| (2)Rubber expansion joint Rubber Bridge Expansion Joint system comprises of 8 NO. Standard models designed to accommodate movement up to 330mm by shear deformation of the elastomer between the steel components. |
| Q:Where are they used to ? A:They are used in Highway bridge decks, Service ramps, Multi- store car parks and so on. |
| Q:What's the construction programs of bridge expansion device? A:(1) Set out and cut Modular Bridge Expansion Joint. (2) Excavate and clean the Modular Bridge Expansion Joint area. (3) Drill holes to locate the anchor bolts. (4) Place the rebar mat and mold. (5) Pour bottom concrete layer. (6) Install comb-shaped steel plate. (7) Pour side concrete. (8) Maintenance the Modular Bridge Expansion Joint. |
