The road expansion joints bridge the structural gap in a roadworthy way. In case of an earthquake, the roadway expansion joint is adjusted to the project-specific seismic displacement. This enables the best possible adjustment of the two components sealing profile and edge construction for the connection to the road. Single-Seal Joints D80 A Closer Look at Bridge Expansion JointsConcrete Mar 01, 1999 · Years ago, many bridges had unsealed joints. A simple gap in the deck accommodated small movements, and finger-plate joints or similar systems accommodated larger movements. Water and debris simply fell through the joints. Transportation departments, however, have paid a price for this joint
The Joint Movements Calculations form (Form DS-D-0129) is to be used to calculate the MR for all bridge expansion joints. This sheet is to be placed in the preliminary report for forwarding to Construction, (RE pending file). Example No. 2 (Attachment :2) illustrates the necessary information to be provided by Design. Joint movement Bridge Expansion Joints - ftp.dot.state.tx.usBridge Expansion Joint Guide April 2019 DESIGN Finger Joint and Modular Bridge Joint Systems (MBJS) For expansion movements greater than 5-in., but are not recommended. These systems tend to be expensive, expensive to maintain, and high maintenance. Consult with the Bridge Division on the use of these joint types. 13 Bridge Joints for Maximizing Driving ComfortBridge joints are commonly found between the ends of two beams, beam end and the abutment, or on the joints position of bridge. They are easy to install, check, maintain and clean. Our products Hengshui JingTong Rubber Co., Ltd. manufactures high-class bridge expansion joints in various dimensions and for different movements.
The maintenance of drainage troughs under finger expansion joints is often difficult due to limited access from below due to height and from above due to the finger joint and traffic. Recently, research was conducted to determine if design changes or equipment may provide a better way of performing drainage trough cleaning. Chapter 28 Expansion Devicesseals are watertight joints which are used in place of sliding plate joints or finger joints in an attempt to keep water and debris on the bridge deck surface. Refer to Figure 12.7-1 for placement of expansion Chapter 9 Bearings and Expansion JointsExpansion Joint Specialist and the Bridge Design Engineer for recommendations and approval. B. Steel Bridges Use L-type abutments with expansion joints at the ends for multiple-span bridges. Semi-integral construction may be used in lieu of expansion joints for single span bridges under 300 feet with the approval of the Bridge Design Engineer.

Doshin Finger Expansion Joints are cantilevered or simply supported steel tooth expansion joints. They are composed of pairs of independent elements with parallel teeth provided in lengths from 3 feet to full roadway widths. The Joints are used to provide support to vehicles as they travel across bridge expansion joint openings. Granor Expansion Joints Large MovementsSteel Finger Expansion Joints Series SFEJ T-Mat System Large movement expansion joints, particularly of the Modular type having movement capacities up to 2,000mm, require careful consideration as to the structural integrity of the bridge in this highly stressed area. Introduction Bridge Expansion Joint, Bridge Joint System We have researched bridge expansion joint systems based on our techniques and experiences through the many processes of bridge construction and as a result, we have finally developed a new expansion joint that does not impact on the body of the bridge and is very convenient for repair work. We have parents on these systems.
13. the expansion joint assembly shall be installed only after the approach 11. see bridge sheet 41 for hopper details. as noted gmc/smg finger expansion joint (2 of 3) finger joint (f). entire assembly shall be paid as item 561.301, prefabricated expansion joint, gr 50) or aashto m270 (astm a572) gr 50, except as otherwise allowed. the 1. Strip Seal, Modular and Finger Expansion Joints Hennegan Oct 28, 2014 · Finger Joints Fabricated steel plate expansion joint systems, such as finger joint assemblies and sliding plate and armor joint systems, are still specified on many bridge projects due to proven long-term structural performance. TABLE OF CONTENTS ~ EXPANSION JOINTS5.8.3 Expansion joints 184.108.40.206 General . 220.127.116.11.1 Policy overview . Although the Bureau prefers jointless construction, some designs require deck expansion joints because of bridge length, bridge skew, use of stub abutments, use of expansion bearings, or other factors. Where expansion joints are necessary it is important that they be sealed
The Granor ETIC® SFEJ series Steel Finger joints are robust Bridge deck expansion joints that accommodate larger movements ranging from 150mm up to 600mm total capacity. These joints should be adopted where the structure gap will open beyond 85mm ULS, in which case the use of a stripseal type single seal element joint will transgress the
