Embodiment Construction

[0033]The present invention utilizes one or more thermal barrier molded bags which may be conveniently placed in openings in members such as walls, ceilings or floors, or in openings such as formed between walls, ceilings and / or floors. in the gaps in the seams. An empty molded bag is placed in the hole or gap, and a flowable firestop material is introduced into the molded bag, causing the bag to expand to fill the space within the hole or gap, and then allowing the flowable firestop material to Hardened in holes or gaps to provide a solid thermal barrier. As used herein, the term "firestop" generally refers to a material that is inherently capable of being flame-retardant or fire-resistant, and a detailed list of exemplary firestop or fire-resistant materials is provided below.

[0034] As shown in Figure 1, a "head of wall" joint gap occurs between the top of the standing wall and the ceiling (prior art). In this figure, the walls are formed by connecting horizontal metal ...

Abstract

The invention provides methods, systems, and devices for installing barriers in openings or gaps in or between structures such as walls, ceilings, and floors. At least one barrier molding bag is positioned in the hole or gap, and a flowable firestop material that is preferably operative to cure or harden, such as a hydratable cementitious slurry, is introduced into the bag to create a barrier in the hole or gap.

Description

[0001] This application is based on pending US Patent Application No. 09 / 999307, filed October 31, 2001 and pending US Patent Application No. 10 / 151333, filed May 20, 2002. technical field [0002] The present invention relates to building elements, and more particularly to assemblies for "head-of-wall" joints between tops and ceilings, "perimeter" joints between floors and upstanding walls, and in building elements. Moldable thermal barriers in other seams, gaps or holes. Background technique [0003] Firestops are thermal barrier materials or combinations of materials used to fill gaps and openings in, for example, the firewalls of buildings and / or joints between floors. For example, firestops may be used in walls or floors to prevent fire and smoke from passing through gaps or openings used by cables, pipes, pipes, or other conduits. Firestops are also used to fill joint gaps between walls, between ceilings and tops of walls (“head-of-wall” joints), and between floors an...
