Abstract
An improved fire resistive joint system for concrete panel walls and like building structures is disclosed. The cool (or external) side of the joint is sealed by a high performance elastomeric joint sealant, preferably backed up by a closed cell backing material, and the hot (or internal) side of the joint is at least partially filled by a compressible resilient mass of synthetic inorganic refractory fiber.
Claims8
An improved fire resistive joint system for concrete panel building members which comprises an elastomeric joint sealant completely sealing the joint on the cold side of the panels and a compressible resilient mass of synthetic inorganic refractory fiber filling at least the external portion of the joint on the hot side of the panels, said fiber mass having sufficient resilience to maintain continuous operative contact with both sides of the joint during movements of the joint.
