A lifted spacer area with two slots or cuts allows the strap through. The plate assembly is slidably mounted along the slot for its proper positioning after the truss are positioned.
Abstract: A method of supporting loose fill insulation in a wall cavity with a flexible netting. The netting is secured to the wall cavity frame by fastening the upper and lower edges of the netting to the upper and lower wall joists with a multiplicity of spaced apart fasteners, and gluing the two side edges of the netting to the left and right vertical studs with a flowable adhesive. A small slit is made in the netting to accommodate the insulation nozzle, which is preferably angled at its end to facilitate reaching into small spaces and cracks. Loose fill insulation is blown into the cavity behind the netting after inserting the insulation hose through the slit in the netting.
Abstract: A modular seal assembly for sealing a circular opening through a wall, usually with one or more conduits (i.e., telecommunication cables) extending through the seal. The assembly includes an outer pressure annulus and a thick inner pressure disc, both of natural or synthetic rubber, EPDM, urethane, or other elastomer. In the outer annulus the elastomer is an annular series of interconnected blocks of length L1 having a central opening of radius R2; a series of pressure bolts compress the blocks axially, expanding the annulus both outwardly and inwardly. The inner disc, which has an outer radius of about R2 and is interlocked with the elastomer blocks of the outer annulus, has a multiplicity of circular layers, much like an onion; the layers are concentric about an opening through which a conduit usually extends.

Abstract: A security barrier system which includes a security lath assembly having a layer of mesh material and a backing material attached thereto. The mesh material is of a gauge and configuration to provide a security barrier. The security barrier system includes application of plaster or stucco directly to the security lath assembly. A surface coating is applied to the plaster layer to prevent the formation and propagation of cracks through the surface. Also included in the barrier system is an uplift control mechanism and expansion and contraction elements which prevent a ceiling structure from being displaced and accommodates structural expansion and contraction.
Abstract: An open but secure kiosk, anchored in the ground, for a full service travel center in an indoor commercial public area is, in one embodiment, substantially rectangular with a small square area removed from each corner and has vertical corner beams, an upper wall portion defined by at least two parallel double upper cross-beams running along the entire upper perimeter of the kiosk, a lower wall portion along the entire lower perimeter of the kiosk directly below the upper wall portion constructed of continuous solid block roughly three feet in height and including the upright side wall of customer counters that form the two longer sides of the kiosk. There are also ceiling cross-beams. Movable grates above the counters close downward and seal the long side walls and there are bright signs at the top of the long walls.
Abstract: A wall panel support member adapted to reinforce a wall and to support the weight of structures such as shelves, cabinets, and sinks which are attached to a wall. The wall panel support member includes a support panel which is mounted between adjacent wall studs by brackets or other mounts. One embodiment of the invention includes a support panel with a groove formed at one end of the support panel which accommodates a lip of a metal stud, thus allowing the surface of the support panel to engage the stud. A bracket which is comprised of a plurality of generally perpendicular angled surfaces is mounted on the opposite end of the support panel from the groove for securing the wall panel support member to an adjacent stud. The bracket includes slots in the surface mounted to the support panel to allow the position of the bracket to be adjusted along the longitudinal axis of the support panel in order to accommodate variations in width between studs.
Abstract: To assist in rapid taping of seams between adjacent drywall units, a tape is provided in rolls. The tape has a first layer of flexible paper material with an inwardly facing pressure-sensitive adhesive coating thereon. A second layer of reinforcing woven fiber material overlies the first layer. A third layer of flexible material overlies the woven fiber material to encapsulate the fiber material between the first layer and the second layer. The third layer has an outwardly facing release coating such that the first layer adhesive will releasably engage the third layer for manual separation of the tape when rolled upon itself. The adhesive is formulated to maintain adhesion even when wetted by an overlying layer of drywall mud. Furthermore, the release coating on the third layer accepts and allows the adherence of drywall mud. The tape may be used in fire wall applications. Perforations may be provided in the tape to facilitate adhesion.
Abstract: A suction chamber is provided in the rear portion of a pad body remote from an external pad supporting surface. The fore end portion of the pad body facing the pad supporting surface is divided into a plurality of sucking compartments for communication with the suction chamber. An air flow passage is provided for communication with the suction chamber. Valve mechanisms are provided in air flow paths between the respective sucking compartments and the suction chamber and are closable by a sucked air flow occurring during vacuum suction. Further, an automatic switching valve is provided in a part of the air flow passage in such a manner that the switching valve is caused to open in response to abutment against the pad supporting surface of the pad body. The air flow passage is formed in such a manner that a direction of force acting to cause the automatic switching valve to open differs from a direction of counteractive force against a spring structure that normally urges the switching valve to close.
Abstract: The invention is directed to a pollution abatement apparatus for use during a polluted window frame (or other polluted structures) removal in order to prevent toxic material from entering the inhabited areas of the building. The apparatus includes a rigid unitary member adapted to fit against the polluted structure within the interior of the building and to surround the polluted structure in an air-tight manner as the polluted structure is being removed from outside of the building. The rigid unitary member is capable of being height adjusted and clamped between the floor and the ceiling after the "rough" and "fine" height adjustments have been made.
Abstract: In outdoor equipment having at least one supporting body (S) for mounting the outdoor equipment body thereon and for fixing the same to the surface of the ground, a floor or wall, it is characterized in that the supporting body (S) is composed of a plurality of body plates (1) which have been machined beforehand in given shapes, and mounting plates (3) which are fixed to the body plates (1) by way of bolts (4) and to the outdoor equipment body, the wall or the ground. As a result, it is possible to provide outdoor equipment which is improved in the problems of maintenance, manufacturing labor, product accuracy, moving and exchanging.
Abstract: A vapor barrier panel is designed specifically for application to the area between the floor joists and under the sub floor and in front of a concrete basement wall. The panel body includes a flat panel section with a flange at the top edge at right angles to the top edge and two flanges down each side. The panel body is thus applied so that the top flange engages against the underside of the sub floor and the side flanges engage against the sides and bottom respectively of the floor joists. The panel is semi rigid so they can be applied in place simply by sliding into position and abutting against a bead of sealant applied to the floor and floor joists or pre-applied to and carried on the outside surface of each flange.
Abstract: An astragal formed as a part of an extruded door sash is described. The astragal is formed integral with the door sash as an elongated forwardly projecting member constituting an astragal base. An elongated detachable cap is releasably secured to the base member and extends forwardly thereof. A core member is disposed internally of the door sash and projects along the outer end edge portion of the sash and at least in part within the astragal. The astragal base member and the door sash form a unitary member.
