Brückenleisten

Brückenleisten are a type of architectural element used in bridge construction. They primarily serve as a transitional component between the bridge deck and the roadway. These elements are designed to accommodate expansion and contraction of the bridge structure due to temperature changes and traffic loads, preventing damage to the bridge and ensuring a smooth passage for vehicles. Brückenleisten are also often referred to as expansion joints or movement joints, depending on the specific design and function.

The design of brückenleisten can vary significantly, ranging from simple, rigid details to complex, multi-component systems. Some common types include finger joints, modular joints, and compression seals. Finger joints, for instance, interlock like fingers, allowing for substantial movement. Modular joints, on the other hand, consist of a series of beams supported by bearings, capable of handling larger movements and heavier loads. Compression seals are typically used for smaller movements and are made of elastic materials. The selection of a particular type of brückenleisten depends on factors such as the expected movement range, traffic volume, load capacity, and environmental conditions. Proper installation and maintenance are crucial for the longevity and effectiveness of brückenleisten, ensuring the structural integrity and safety of the bridge.
