The SJS-FP-FR System is designed to provide a watertight, trafficable joint system in large 4-inch (100mm) and larger joint openings, in decks of split-slab design. SJS-FP-FR is a fire-rated system that expands the use of the SJS System to waterproofed split-slab deck designs through the use of structural-slab mounted supporting legs with integral waterproofing side sheets that integrate with the deck waterproofing membrane.
As with the SJS System and the SJS-FP systems, it is designed for larger trafficable joints, often found in seismic applications. The aluminum (or stainless steel) coverplate provides a durable and high-load bearing surface. The SJS is constructed from two horizontal joints pre-assembled in parallel adjacent to a heavy-duty extruded aluminum spline. The spline acts as a receptor for attaching the surface-mounted traffic plates that bear vehicle and other loads. The result is a system that offers features and benefits not found in alternative products intended for large, horizontal structural joint gaps.
