How to equip a deformation seam?
Bridges, overpasses, overpasses, and road junctions are created to overcome obstacles. Most often, these are rivers, areas with complex terrain, motor roads, and railways. In modern bridge construction, reinforced concrete construction prevails. Therefore, when erecting such artificial structures, the design of the structure provides for the placement of expansion joints.
Expansion joints in bridges are located between span structures. They ensure uniform distribution of loads that can be caused by mechanical and climatic influences, horizontal, linear-vertical, and angular movements.
Previously, resins were used to seal such joints. The purpose of the resin was as follows: the resin solved the problem of waterproofing and compensating for the deformations that occurred.
Modern bridge construction involves the construction of structures that occupy much larger areas, which has led to the need to place expansion joints of great width. In the case of using mastics, this becomes impractical. Mastic, due to its technical properties, is unable to withstand such high deformations. Already during operation, pits appear in places of expansion joints, the asphalt cracks or rises as a hill above the main level of the coating. Expansion joints in bridges
It is precisely to solve such technically complex tasks that the specialists of TM "ARFEN" have developed high-strength profile systems for expansion joints . Bridge and road joints made of high-quality steel and durable rubber are able to ensure the longest possible service life of the paving stones. Steel elements provide durability and resistance to wear under the influence of high loads and perfectly compensate for shifts and vibrations of the structure due to various influences. At the same time, the rubber gasket absorbs vibrations of the bridge or overpass, softens the friction of steel parts and ensures the watertightness of the expansion joint.
Therefore, we recommend using the ARFEN TM expansion joint profile as the optimal option for installing expansion joints in bridges, roads, overpasses, and highways.
