Fire barriers for the spaces formed by intersecting architectural expansion joints

摘要

Multi-layered, fire-barriers each sized and shaped for installation into accepting intersection-spaces formed by the spaced-intersection of at least two expansion-joint spaces that occur between two adjacent spaced structural building units, each of said expansion-joint spaces defined by a plane, said plane defined by a set of three non-colinear points with each point defined by a set of x, y, z coordinates from the same coordinate system with no two of said coordinate sets being identical. The fire-barriers are shaped for use in 2-way planar, L-shaped expansion-joint spaces, T-shaped, cross-shaped, V-shaped, and vertical/horizontal L-shaped corner expansion-joint spaces, for example, and may comprise at least one layer of: protective cloth, insulating blanket, intumescent material, and mechanically supporting layer. The barriers prohibit the travel of fire, heat, or smoke through the flue-like channels created by the expansion-joints of a structure are provided ready to install in a one-step, drop-in process.
