The purpose f the present invention is to provide an improved panel unit for building construction, wherein the same is composed of prefabricated parts adapted for' factory assembly 'or for convenient assembly on the building site.

The general object of the invention is to pro# duce a panel unit of strong light weight construction adapted for use in the formation of the Sides and roof of a building, or as an interior` par- `tition, and wherein the construction `of each unit renders the same fully capable of resisting the" elements; possesses high heat insulating proper-v with similar panels, the plane of the section be` ing indicated by the line II-IIof Fig. 1;

` Fig. 3 is a detail horizontal sectional viewtaken I through a slightly modied form of panel; Fig. 4 is a vertical transverse sectional view taken through apanel on the plane indicated by the line IV-IV of Fig. 1; c Fig. 5 is a detail horizontal sectional view on 3o' the plane indicated by the line V--V of Fig. 4. Referring more particularly to the drawing, the numeral I designates the improved vwallforming panel comprising the present invention in its entirety. The panel comprises a substantially rectangular marginal frame 2 which', in its preferred form, is composed of structural steel angle members having mitered corner joints 3,

which are welded or otherwise'secured together y tol produce a rigid frame construction.

405' In combination with this outer frame, each of the panels includes apair' of rectangular inner and outer sheets and 5 respectively. While these sheets may be formed from any suitable materials possessing requisite strength for wall-forming purposes, I preferably form such sheets from pressed composition materials, such for in' stance as vegetable orrmineral bers. Thus the inner. sheet ll may be composed oi pressed asbestos known commercially as Flexboa-rd, whereas the outer sheet E is preferably composed ofpressed wood ber, sold commercially under the name Masonite Each of these sheets may be formed in rectangular sections 4 ft. wide by 8' ft.fhigh, possessing a thickness of approximately 1/4- yin., While. the angle` members comprising the.

(ci. iss- 34.)

framegv2 possess thema'rginal dimensions rof ther sheets 4,' and each of the flanges of said angle' members is approximately 2 in. wide and it!" f thickl :When assembled, the adjoining inner faces ofthe sheets ll and 5` are 'spaced approxiy 5i? mately `l andag in. apart. While these dimensions are 'not intany sense critical, nor are the materials for forming the panel, yet the specic description of the same'is given in order to afford a more complete understanding of the preferred form ofthe invention. i K f' The outer flange or leg 46 of each frame angle?- has its 'inner' surface provided with a plurality y of spaced horizontally orperpendicularly extend'- ing. steel studs l, spa-ced approximately .125 in. 15.8 apart. 'Ihe inner ends of the studs 'l are welded, asat' to the inner surfaces ofthe legs or iianges` 6 of z the angle frame.' This construction is f em,- ployed in lieu of passing bolts through openings inthe legs orflanges '6,' thus preventing. the studs zur; 1

i from beingfaccessible from the outside'of the' building in which the panelsare situated, andf enables the outer surfaces ofthe-legs-orflanges 6 t'o be smooth and unbroken ,andi are devoid-.ofv bolt heads`,'rivets, nuts or other fastening der 25g. vices hitherto employed in securingthe-Sheetszteiy the angle members. The construction presents;

a more' attractive y'external appearance 'as .well 'as oneo-f requiredmechanioal strength;v

terns or* guides, have their marginal :portions drilled' or= bored at 'spaced intervals l'to produce? openings- 9, which are so arranged;as.'tol;r'eceivez the studs 1, yso that the outer marginal faces'off the sheets 5 will 'directly contact thejinner sur-rA 315i facesof the frame legs 6, as'shown in Fig; 2-.4 kv

f The inner or free ends of the studs ll' arefp'roef' videdvwith! axially disposed threaded bores :lili o which are adapted to receive the-threadedfshanks@ ofheaded cap screws l l. These cap`r screws passa 4Q;

through marginally disposed openingszlzfwhich" are formed by'f'actoryv operations inthe inner sheet 4. Surroundingv these studs 'l'. are metallic sleeve-like` separatorsl t3 which aref-interposed.

between the inner complemental surfaces ofthe 453i `sheets @and 5k and serve to maintain'fsaid-sheets;

The outer sheets 5, by means of'suitable` pate the inner surfaces of the sheets 4 and 5, is filled with bats of mineral ber I6, producing excellent thermal insulation in addition to that normally afforded by the composition materials from which the sheets 4 and 5 are preferably formed. The heads of the screws may be countersunk in the sheet 4, if desired, to provide for a smooth internal nish.

The construction set forth may be easily assembled either in the producing 'factory or` on the site of the building operation, the former procedure being the ordinary course followed. The parts of the panel, however, are all preformed under factory supervision so that at the time of assembly all that is required is the mere placing of the parts of the panel in proper relative order, and the securing of the parts in such order by the tightening of the screws Il. ykAdjacent wall forming panels may be secured together by suitable fastening devices I'l which pass transversely through the inwardly extending flanges or legs I5 of the angular members comprising the fram-e 2. As illustrated in Fig. 2, the inner panels and the insulation are provided with recesses I8 in the vicinity of the fasteners l1. After adjacent panels have been rmly secured together, the recesses I8 are closed by means of cap plates I9 and attaching screws 20.

. To prevent buckling or bulging `on the part of the sheets 4 and 5 at the center thereof, channelshaped spacing strips 2| are disposed at spaced distances throughout rthe length of the panel. These strips have the flanges provided with registering openings adjacent their'ends to permit the strips to be positioned, as shown in Fig. 4, between the sheets with a stud 4'l extending through the openings at each end. This serves to: prevent the misalignment of the strips and their accurate location where they are most useful. The sheets are held in engagement with the strips through the use of metal fastening scr'ews 22. j

The panels described are preferably employed in the formation of building side Walls, and the roof-forming panels are slightly modified in design, as disclosed in Fig. 3. `In this figure, it will be noted that the rectangular frame 2a is channel-shaped in cross section, being preferably produced from sixteen gage galvanized steel.

ll The composition sheets 4a and 5a engagewith the outer surfaces of the spaced parallel legs of thechannel members `comprising the frame 2a, and are secured to said frame by means of headed screws Ila which pass through registering `openings formed in said sheets and frame legs, with the Shanks of said screws being received within threaded bores provided in separators l3a, the latter serving to strengthen the legs of the channel members and to maintain said legs in4 properly spaced order. lA body of mineral wool IBa. is preferably disposed between the sheets 4a and 5a for thermal insulation purposes.

These panel units may be readily joined to-y gether in order to produce a strong, light Weight inexpensive building construction. It will be understood that the exposed surfaces of the composition panel sheets may be suitably finished as by painting or otherwise to impart a desired appearance. The construction is particularly adapted in the erection of substantial but low cost buildings.
