Description
Product overview
When modular expansion joints exceed transportable length or are installed in phases, their elements must be joined on site. mageba has developed a fatigue‑resistant bolted field splice for the TENSA®MODULAR expansion joint that uses only bolted connections, eliminating the need for on‑site welding. This solution simplifies logistics, speeds up lane‑by‑lane installation and ensures higher overall quality by concentrating welding and corrosion protection in factory conditions.
Key characteristics
Principle
The bolted field splice connects modular expansion joint segments using high‑strength bolted connections and a tailored hinge detail. All welds and protective coatings are executed in the factory prior to delivery, so on‑site assembly requires only bolting. The design targets fatigue performance comparable to welded splices while reducing site welding risks and schedule impacts.
Applications
Designed for use in bridge and structural expansion systems where TENSA®MODULAR joints are delivered or installed in segments. The bolted field splice is suitable for long joints, phased construction and projects requiring lane‑by‑lane installation, temporary removal or staged replacement of modular joints.
Additional information / image captions
Detail and section views illustrate the bolted splice for single centerbeams and the fully assembled TENSA®MODULAR expansion joint. The drawings highlight bolt patterns, hinge locations and areas where factory corrosion protection is applied prior to installation.
