ABSTRACT:
The present invention relates generally to insulated pre-formed wall panels and to the construction of walls such as basement walls therewith.
In co-pending U.S. patent application Ser. No. 08/508,722 filed Jul. 28, 1995, the disclosure of which is incorporated herein by reference, Michael J. Kistner and Paul J. Rowe, two of the inventors for the present application, disclose a prefabricated wall panel which comprises a unitary combination of a member having a generally planar portion which has an outer surface which defines the outer surface of the erected wall and a plurality of rib portions integral with the planar portion and extending from the inner surface of the planar portion thereby defining voids therebetween for receiving insulation. The wall panel further comprises insulating material attached, as strips or otherwise suitably attached, to the edges of the rib portions which are remote from the planar portion. A nailer strip, which may be a screw nailer or other suitable means, is applied to each insulating material strip. After the prefabricated wall panels are installed and insulation is placed in the voids, wallboard defining the inner surface of the wall is attached to the nailers to complete the wall construction. Such a prefabricated panel is thus provided to eliminate conductive pathways between the rib portions and the wallboard so that greater insulative capability may be achieved in a panel from which a wall may be easily yet reliably and inexpensively erected.
The aforesaid application also discloses an embodiment of the nailer strip which is composed of a spring material and which is folded to extend around sides of the respective insulation material strip, and a pair of edge portions thereof extend into the respective rib portion for anchoring the nailer strip and the insulation material strip to the rib portion.
It is an object of the present invention to enhance the insulation capability of the panels.
It is another object of the present invention to improve the stability of walls constructed and being constructed with the panels.
It is a further object of the present invention to improve the quality and appearance of walls constructed with the panels.
It is yet another object of the present invention to provide a seismic resistant attachment of the panels to floor slabs.
In order to enhance the insulation capability of a panel, in accordance with the present invention, the edge portions of the nailer strip are insulated from the rib portion to limit thermal conductivity from the rib portion to the nailer strip.
In order to improve the stability of a wall constructed and being constructed with the panels, in accordance with the present invention, a corner panel is provided which “braces” a wall portion to which the free-standing corner panel is attached. Corner panels are also provided, in accordance with the present invention, to achieve a “bay window” effect or the like to meet aesthetic or functional requirements.
Further in accordance with the present invention, one or more first block-outs for forming the rib portions which extend from the inner surface of a first planar portion are removed from a molded corner wall panel while the molded corner wall panel is held stationary after which one or more second block-outs for forming the rib portions which extend from the inner surface of a second planar portion which forms a corner with the first planar portion are then removed from the molded corner wall panel.
In order to provide a seismic resistant connection of a panel to a floor slab, the nailer strip for a corresponding horizontal rib portion thereof is nailed or otherwise suitably attached to the floor slab, and a cushion material is disposed between the nailer strip and floor slab to allow some movement therebetween.
The above and other objects, features, and advantages of the present invention will be apparent in the following detailed description of the preferred embodiments thereof when read in conjunction with the accompanying drawings wherein the same reference numerals denote the same or similar parts throughout the several views.
