Jul 01, 2014 · A finger-joint always consists of two plates, as shown in the figure. The expansion capacity of a finger joint is determined by the length of the fingers crossing over each other. Download :Download full-size image; Fig. 1. Structure of a finger-type expansion joint:(a) plane view, (b) side view, and (c) idealized joint-plate for design.
Bridge Deck Expansion JointsBridge deck expansion joints are divided into the following three groups. 1. Modular expansion joint systems including finger and sliding plate dams, with 2 to 16 in. of movement, but generally more than 13 in. of movement. S. H. Dahir, Pennsylvania State University, Middletown, Pa. 17057.
B- Finger Joints can be used for large movements as well The open joint typically anchored to concrete decks Metal troughs are usually constructed beneath the joint to redirect runoff. C- Sliding Plate Joints Two overlapping steel plates made to stop water and rubble infiltration Allow a smooth joint surface. 3- Large Movement Joints
China Steel Plate Finger Expansion Joint - China Finger Steel Plate Finger Expansion Joint Haider unit finger expansion joint with multi-directional displacement capability is a patented new generation bridge expansion joint
Expansion Joints Ltd - Bridge Expansion Joints Camelot FingerFinger Camelot expansion systems are designed and manufactured to adapt to the movements of large expansion bridges. In general, they consist of two main components of steel shaped comb, construction asymmetric teeth resting on one plate sliding of the two. Plates - comb are made of high-strength steel, treated against corrosion.
The teeth are also wider compared to the fingers of the finger plate type expansion joints. The finger plates are supported on one side, the tips remaining free as cantilevers and as such the thickness of the finger plate is more. Expansion gaps in such joints are also more. This type of expansion joints are used in large span steel bridges
Finger Joints RJ Watson, Inc. - Bridge & Structural RJW Finger Joints are a simplistic design with no moving parts that are designed to accommodate any bridge deck expansion joint movement. Finger Joints are cantilevered or simply supported steel tooth expansion joints. They are comprised of pairs of independent elements with parallel teeth provided in lengths from 3 feet to full roadway widths.
Freyssinet Expansion JointsThe expansion joint is without doubt the element under most strain in an engineering structure. Expert in managing the functionalities and stresses to which expansion joints are subjected, Freyssinet develops products designed to meet specific site and climate conditions and specific operational conditions. 20 30 50 60 65 75 80 100 110 150 160 200
Jul 15, 2011 · I don't think an article about a bridge expansion joint should be used for all structure types for recommendation on expansion joints. I have three buildings over 200m long that have expansion joints, have reviewed the buildings over the past 5

mageba expansion jointsand high driver comfort. TENSA®FINGER sliding finger expansion joints are thus ide-al for use on bridges near residential areas or in other noise-sensitive zones. Surface profiling To improve the ability of vehicle wheels to grip the surface of the joints finger plates, they can optionally be delivered with a 2mm-deep surface pattern.Steel expansion joint - TENSA-FINGER RSFD - Mageba - for Description. mageba TENSA-FINGER RSFD cantilever finger joints are bridge expansion joints for movements of up to 500 mm. Their robust steel edge profiles have strong anchor loops for concreting to the main structure, resulting in excellent fatigue resistance. These profiles support finger plates at each side of the bridge gap, the fingers which cantilever out over the gap.
