Abstract

ABSTRACT

INSULATION

A support fox reconstituted wood or of vegetable fibers is used instead of natural wood furring, blocking or the like to connect a supporting and supported wall, ceiling or similar enclosing surfaces. The support is provided with one surface for juxtaposing to the supporting wall, and an opp-osing surface. The opposing surface is recessed to receive the nails to the supporting metal elements for connecting the support to the supporting member inserts for insertion in said recess complementary thereto when viewed perpendicular to said one surface.

Description

This invention relates to a wall support for attachmen~
on o~e surf~ce t~ -the face of an ~xisting o~ new struccure arld to support on an opposing surface other sheathing, enclosing, ornamental or structural members.
The type of application fox which the invention has been developed is in the type of structural use perEormed by Eurring, blocking and similar applications where (at present), wood usually in strip form, is attachecl by screws, nails or other mechanical fastenings to an existing wall such as a masonry, concrete, or metal or wood framed wall and in turn is connected to another element, usually a panel type surface, to support a weather protection or ornamental finish. The supported panel type surface may, for example, be aluminum siding, plywood or parti-culate board sheeting or the like in an exterior application; or may be dr~all or panelling in an interior applicationO The invention is thus concerned with the provision of furring, bloc]sing ~;
ox the like for connection in a structure between a supporting and a supported wall or other member.
Prior wooden members for use in furring, blocking or the like have been nailed or equivalently fastened to the support-ing wall by metal members hammered in place, the nails ox equiv-alent metal members extending through the Eurring or blocking memberO Such metal acts as a high concluctivity conductor of heat through the furring or blocking memher and hence contributes materially to the heat loss at the structure in which it is containedO While, in other times, such losses were tolerated, it is doubtful that such avoidable losses will be tolerated in -these times of high energy shortages. `
Accordingly this invention provides a two part member made of recsnstituted wood or of vegetable fibers to act as a furring, hlocking or equivalenc member or as a member designed to ~5~
control ~ supporting to a suppor~ed wall memb~x and atta~hed to the suppor~ing wall member by a nailed or equivalent metal connection, or fastening.
In the invention the joining member is provided with a first surface to be placed against the supporting wall and a second surface on the opposed side of the joining member Erom the first surface, from which a nail or equivalent metal membsr may be driven. At locations on sa ~ second surface where it might be desired to provide such metal members, the second surace i5 recesse~ so that nails or equivalent metal joining members may be driven through such one part at those locations.
Plugs or filler members constitute the other part of the inventive joining member and are inserted in the recesses to provide heat insulation over the heads of the nail or the ends of the metal member. In this way the reconstituted wood or vegetable fiber member provides a mount for a supported member to be attached , , .
thereto but does not have a metal heat conducting path there- -through as in prior natural wood members.
It is well known that in ornamental woodworking, a nailing area in wood may be recessed and an insert or plug inserted in the recess over the nail head when the latter is in place. However, this has so far as is known by applicant, been previously do~e only for ornamentai as opposed to heat insulation reasons.
In drawings which illustrate a preferred embodiment of the invention:
Figure 1 shows a cross~section of the invention applied both to the inside and to the outside of a masonry wall;
Figure 2 is a perspective view of the application of a member in accord with the invention.
In the drawings Figure 2 shows a masonry wall having a '- 2 - ;

~ s~
surface 10 to which Eurrin~J is to be attached. A furring strip 12, in accord with the lnvention, is provided with a surface 1~
designed to be placed against wall surface 10 and is provided on the opposite side with a surface ?2 to which inside or outside panellin~ is to be attached for support through the strips 12.
The surface 22 is recessed, here by a ~roove 24, whose root surface 27 is designed to receive nails 11 or equiv-alent metal msmbers for driving thexethrouyh to attach -the s-trip 12 to the masonry wall for support oE the Eormer by the latter.
Equivalent me~al jolning members include screws or staple members. In order to ensure easy application of the metal joining members the recess is preferably provided with a minimum dimension (viewed perpendicular to the suppor-ting wall surface 10 and surface 14) large enough to receive a hammer or equivalent driving tool. Such preferred minimum dimension is ~ 2l~D In the embodiment shown such minimum dimension is the width of groove 24 viewed perpendicular to surfaces 10 and 14.
There is provided a strip 26 complementary to the recess 21 (when viewed perpendicular to surfaces 10 and 14) to he located therein in any sultable manner such as by gluing, friction pressure or by nailing. If nailing is used such added nails should be arranged not to contact the nails 11 or metal members which attach the strip 12 to the masonry wa]l.
The main strip 12 and filler stxip 26 are constructed mainly of reconstituted wood or of vegetable ~iber material with suitabl~ bonding and structural qualities for the purpose of transferring stress from a supporting to a supported wall. The ~;
invention does not contemplate the use of natural woodO With the material mainly comprising reconstituted wood or vegetable ~ fibers, the main strip 12 with its filler strip 26 supplies a :

stress transEer member which avoids the p,xesence oE any metal heat conducting path therethrough~
The supportecl wall may be supported by nailirly or means of at-tachment to the main strip 12 (not of course merely to filler strip 26, whlch is not usually designed for the '~ -transer of stress to membex 12).
The preerred embodiment shows a recessed main strip 12 where the recess is a longitudinally extending groove 24 and the iller ~trip 26 is a complementary longitudinally extending member. ~Iowever, the recesses in the main strip 12 and complementary fillsr member 26 may be otherwise shaped (when viewed perpendicular to surfaces 10 and 14), i.e. the recess may be circular, rectilinear or otherwise with a comp~
lementary filler member. The minimum dimension of the recess ;' will however be preferably at least 1-1/2" (viewed perpendicular to surfaces 10 and 14) to allow sasy application of a fastening '~
tool inside the recess. The filler will be complementary to the recess in tha main ~oining me~er (here e~bodied by strip '~
12) as viewed perpendicular to the supporting wall to provide good insulation qualities. The recessed side of the strip opposing the supporting wall will usually be rendered flush by the fiIler but it will be realized that the criteria for this will be the structural and functional ~ualities oE the main strip rather than appearance.
Figure 1 shows members 12 of the typs shown in '''~
Figure 2 applied to mount aluminum siding 30 on the outside surface 10 of masonry wall and drywall 31 and panelling 32 attached by membsr 12 to the inside surface 10 of the masonry ,`' `' wall. Insulation is shown between the drywall and the masonry formed by the furring strips in accord with the invention, The _ 4 - :

filler stri.ps 26 are shown in place insulating the wall ayainst heat construction and losses alony nails 11~
The means of attachment of the aluminum si.dewall, on the other hand, and the drywall, on the other hand, to the main portion of the inventive furring strip are not shown as such means are well known to those skilled in the art~
The inventlve strip may be used as a structural force transfer member in wall, floor, or other areas which are considered to be within the scope of the invention.
