Abstract: The present disclosure provides a clip for securing a support channel in an acoustical ceiling mount and a building construction having a wall, flooring, or ceiling assembly that displays improved acoustic characteristics. The clip includes a body having a penetration-resistant base, a channel interface extending outwardly from a portion of the base configured to engage the support channel, and an opening in another portion of the base, a grommet engaged in the opening of the body, and an insert engaged in the grommet. The channel interface includes at least a first slot configured to receive a channel fastener to secure the support channel to the clip. The clip may be operatively coupled with a support channel and disposed in a building construction between the support channel and a finished interior element.

Abstract: A floor-ceiling assembly is provided for joined upper and lower modular construction units, including a floor surface of the upper unit using structural cement panels; a floor grid including at least one floor joist and at least one beam each having an upper surface receiving said structural cement panels, a web and a lower surface. At least one connector plate is secured to the lower surface. A ceiling framework of the lower unit has at least one ceiling beam and at least one ceiling joist secured to each other, at least one of the beams is secured to the at least one connector plate. A resilient channel is secured to an underside of the ceiling framework, and a ceiling panel is secured to the resilient channel.

Abstract: An assembly for reinforcing a structure is provided. The assembly generally includes a rigid sheet and a bracket. The rigid sheet is adapted to be adhered to the structure. The bracket includes a first leg and a second leg. The first leg is adapted to penetratingly engage the structure. The second leg adheres to the rigid sheet. The first and second legs extend substantially perpendicular to each other.

Abstract: A fastener clip for use in constructing a security wall system, and a security wall system so constructed are disclosed. The fastener clip has an elongate smooth surfaced planar body, a counter-sunk fastener recess formed s centrally within the body, a fastener opening defined within the recess and extending therethrough, and at least two spaced prongs formed as a part of the body which extend away from the body in a common direction. The fastener recess is sized and shaped to fit within an opening of a rigid mesh wall panel placed in registry with at least one structural frame member of a building. A threaded fastener is passed through the fastener opening and driven into the frame member to seat a bottom portion of the recess and a driving head of the fastener against the frame member.

Abstract: A drywall installation apparatus includes a support for holding a piece of drywall to be installed on a stud wall, an extension to adjust the length of the drywall installation apparatus, and a base to which a lifting mechanism may be coupled to raise the drywall installation apparatus and the piece of drywall being supported into a desired position for installation on a stud wall. The drywall installation apparatus further includes an alignment member to assist in orienting properly the piece of sheetrock to be installed on the stud wall.

Abstract: A load bearing-metal panel and stucco substrate cooperates with adjacent panels to form load bearing studs that are interconnected by a metal lath stucco substrate to which stucco can be applied, each panel being generally in the form of a channel in which insulation can be placed, whereby a wall structure can be formed by adjacent placement and interconnection of panels.

Abstract: Fire and heat resistant metal structural members and a method of fabricating same are provided. The structural members of the invention comprise a metal substrate element, a discontinuous tie coat layer comprising an inorganic binder adhered to a surface of the structural element, and a continuous layer of a hydraulic cement-based fireproofing composition adhered to the tie coat layer and the exposed areas of the metal substrate. The discontinuous tie coat layer of the inventive structural members can substantially diminish or prevent the delamination of the fireproofing layer from the metal substrate under ambient temperature and high heat conditions.

Abstract: Sheet metal formed into J-shaped or C-shaped cross section clips or channel that may contain short tabs struck out of the wide side or sides for positioning the clips or channel on a wood 2.times.4 to convert it effectively into deeper framing members such as a 2.times.6, providing room for the additional insulation required for present day energy conservation.

Abstract: A masonry block comprises pairs of spaced opposed side walls and spaced opposed web walls forming a cavity therebetween. An insulative plate of thermally insulative material is disposed within the cavity. The insulative plate extends across the cavity from one to another of the web walls. The side walls each include a portion spaced from the insulative plate so as to define an air cell therebetween extending from one to another of the web walls. The side walls each further include another portion projecting into engagement with the plate to form an air barrier extending across the air cell from one to another of the web walls. Upon forming a wall with such insulated blocks, the air cells are sealed-off from one another to limit convection within the wall.
