Fire, thermal, and/or sound resistant confined space construction

Abstract

A structure having a confined space. The structure includes: (a) a first building unit, (b) a second building unit, (c) a confined space located between the building units, and (d) a structure connecting the fire resistance rated, confined space to the first unit and the second unit. The confined space includes: (i) an interior support structure, (ii) an outer membrane on each side of the interior support structure, (iii) a substantially organic material between the outer membranes, and (iv) at least one secondary support member attached to the interior support structure for preventing bowing of the outer membranes. The confined space provides fire, sound, or thermal resistance and combinations thereof.

Description

BACKGROUND OF THE INVENTION[0001](1) Field of the Invention[0002]The present invention relates generally to a structure having a confined space and, more particularly, to a confined space located in a web truss assembly, the confined space being filled with an organic containing material having a minimum installed density for preventing gaps. The confined space provides fire, sound, or thermal resistance, or combinations thereof.[0003](2) Description of the Prior Art[0004]Multi-family residential constructions typically include separation walls and floors constructed of wood members and having an insulating material between the units. These wood members may include dual two-by-four framing with a drywall surface on both sides of the framing. In many cases, this type of construction requires that the drywall be attached to an interior surface in a gap in the framing after the framing is placed upright to serve as a wall. After the framing is placed upright, material may be positioned...

AI Technical Summary

Benefits of technology

[0008]The present invention is directed to a structure having a confined space. The confined space may be fire resistance rated, and may be filled with a substantially organic material barrier of a minimum installed density of about ½ pound per cubic foot. The structure may include: (a) a first building unit, (b) a second building unit, (c) a confined space located between the building units, and (d) a structure connecting the confined space to the first unit and the second unit. The confined space may include: (i) an interior support structure, (ii) an outer membrane on each side of the interior support structure, (iii) a substantially organic material between the outer membranes, and (iv) at least one secondary support member attached to the interior support structure for preventing bowing of the outer membranes.

[0016]Accordingly, one aspect of the present invention is to provide a structure having a confined space. The structure may include: (a) a first building unit, (b) a second building unit, and (c) a confined space located between the building units, the confined space being filled with an organic containing material having a minimum installed density for preventing gaps having only outer membranes. The confined space may provide fire, sound, or thermal resistance and combinations thereof. The confined space may provide improved fire, sound, or thermal resistance over existing structures, such as those which include sprinkler systems for fire control.

[0017]Another aspect of the present invention is to provide an organic containing material confined space for a structure. The confined space may include: (a) an interior support structure, (b) an outer membrane on each side of the interior support structure, (c) a substantially organic material between the outer membranes, and (d) at least one secondary support member attached to the interior support structure for preventing bowing of the outer membranes. The confined space may provide fire, sound, or thermal resistance and combinations thereof.

[0018]Still another aspect of the present invention is to provide a structure having a confined space. The structure may include: (a) a first building unit, (b) a second building unit, (c) a confined space located between the building units, and (d) a structure connecting the fire resistance rated, confined space to the first unit and the second unit. The confined space may include: (i) an interior support structure, (ii) an outer membrane on each side of the interior support structure, (iii) a substantially organic material between the outer membranes, and (iv) at least one secondary support member attached to the interior support structure for preventing bowing of the outer membranes. The confined space may provide fire, sound, or thermal resistance and combinations thereof.

Problems solved by technology

This process is expensive, labor-intensive and time consuming.

A similar problem exists in the confined space between the walls or floors of a building.

However, once an outer membrane is attached to the studs or truss, the insulation therein may cause bowing of the outer membrane.
