CON CRETE BUILDING FORM.

Specification of Letters Patent. Patented June 2'7, 1922..

Application filed July 6, 1920. Serial No. 394,195.

To aZZ "(11720171 it may concern:

Be it known that 1. PAUL J. HUEBER. o Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful improvements in Concrete-Building Forms. of which the following, taken in connection with the accompanying drawings, is a full. clear, and exact description.

This invention relates to temporary forms for concrete building structures and to the method of erecting the same. the main object being to provide a system of correlated "form sections which may be easily and eXpedi-: tiously erected or assembled in a secure manner for receiving plastic concrete for walls, columns. floors and various other parts during progressive building.

In other words. I have sought to provide a system of terms capable of being assembled in many different combinations for producing all-concrete buildings of widely varying designs.

Another object is to render the assembled form sections substantially self-sustaining during the process of erection and filling in of the concrete.

A turther object is to enable the form sections to be easily and systematically removed and reused in the construction of other con. crete buildings without material loss from deterioration or breakage.

Other objects and uses relating to specific devices oi. certain torm sections will be brought out in the following description.

In the drawings:

The method of erecting the forms for the various parts of the building, briefly stated, consists-- First, in laying a suitable concrete foundation or footing course to the desired level and permanently anchoring therein at predetermined intervals throughout the ing to the width of the spacing blocks.

Fourth, securing a temporary stiffening frame to the upper portions of the several interior studs and bracing the column form tosaid studs.

Fifth, attaching temporary girder forms 'to and betweenthe studs and column forms, and

Sixth, placing the temporary wall and floorpanels in operative position andsecuring them to their respective studs, girders and columns, after which the spacing blocks, wall studs, girders "and panels for thewalls a11cl'fioo1*s"-1i1ay be continued indefinitely for successive stories I with such alterations as may be necessary for modified details ofconstruction; it being understood that the foregoing is intended only as a briefstatement of the general plan of erection of the forms and not as a specific method of assembly,- which will be hereinafter more fully described.

Foundation.

In carrying out the' objects stated, a. con- "crete foundation or footing course -l is firstlaid w1thout forms in a trench, as

A, which is made to the desired dimensions and extended under the entire wall with its upper face substantially horizontal orlevel to receiveand support the concrete superstructure and also the temporary forms therefor, as will be hereinafter more fully described.

A series of previously formed concrete" spacing blocks 2 (Fig. 6) are placed at suitable intervals alongand upon the longitudinal centers of the upper faces of the footlngcourse 1 and are of considerably less width thanthat of the footing course,

' or substantiallvthe same width as the width or transverse thickness of the concrete wall which is to be erected upon the footing course, each spacing block having incorporatedt herein a U-shaped anchor bolt --ahaving its opposite arms protruding below. the lower face of the block, as shown in Fig.

G--: and embedded in the footing course -1, while the latter is in a more or less plastic state for firmly holdingthe block in a fixed and permanent position on the footing course, said block being also provided with a transverse bolt opening --a forn'eceiving a clainpingboltpresentlydescribed by which certain temporary form sections 3- are clamped in place.

These form sections 3- preferably consist of metal faced wooden strips running lengthwise of and upon the upper face of the footing course 1 and clamped against the opposite side faces of the blocks -2 by means of bolts 4 which are passed through the bolt opening a'- in the blocks -2- and also through registering apertures in the base plates or strips 3-, as shown more clearly in Figure 5- each bolt having one end provided with a head for engaging the inner face of one of the strips, while the opposite end is provided with a diametrical slot for receiving a wedge -5 for engaging the outer face of the opposite strip and thereby firmly lock ing the base plates or strips -3 to the separators preparatory to erecting other form sections, it being understood that the bolt openings in the separator blocks 2 and form sections 3 are sufliciently large to permit the bolts -a to be easily inserted and withdrawn when the locking keys 5 are removed.

These base plates or strips 3- may be of anysuitable length convenient forhandling, but preferably terminate at one orthe other of the spacingblocks -2- so'that their adjacent ends may be clamped against the spacing block by the same clamping-bolt "-4 and wedge 5, the meeting ends of the sections --3-being rabbeted and beveled as shown in Fig. 5- to permit them to overlap one upon the other and to be readily placed in operative position and removed when the bolts 4:- are withdrawn, the overlapping ends of one or more sections serving also to assist to hold the adjacent sections in place as shown more clearly in Figure 5.

Additional clamping bolts 6 (Fig. 11)

are inserted in registering openings inthe oppositestrips 3 some distance from and between the bolts -4L or spacing blocks -2- for holding the lower ends of interior and exterior stud sections 8- in operative position upon the correspondingstrips or base plates, as shown more clearly in Figures 2()- and 21; the inner ends of said bolts -6 being provided with clownwardly offset ends -6- seated in recesses wholly within the adjacent faces of the strips 3, while their opposite ends are slotted to receive wedge shaped keys -bfor engaging the adjacent faces of the studs =-8 and strips -'-3--, as shown more clearly in Figures 20- 'and 21, thereby firmly locking the studs to the strips.

The upper'outer corners and upper'inner corners of the'exterior and interior strips -3, respectively, are abbeted longitudinally, and'their upper faces beveled in opposite directions to receive the lower edges of the stud sections --8 and 9- and suitable panel sections hereinafter described, said lower edges of the stud sections ,and

panel sections being similarly rabbeted and beveled to permit said sections to be easily removed and replaced from and upon their respective strips -3 when the locking keys b are removed, the lower edges of the studs being recessed to receive portions of the bolts 6, as shown more'clearly in Figure 21 and are reinforced by a metal wearing plate Z) for engagementby the key Z).

In practice the interior footing plate-3- is preferably laid upon the upper face of the footing course ,1 before the latter is set and before the spacing blocks 2 are placed in operative position so that the latter may be correctly alined against the interior plate lengthwise of the footing course in anchoring the same thereto, after which the exterior footing plate 3' isplaced in opthe adjacent faces of the spacing blocks.

The spacing blocks 2- determine the amount of separationor space, as 7-, be-

' tween the wall studs and also between the wall panels hereinafter described, and, there fore, determine the thickness of the concrete wall which is to be progressively erected between the wall studs and between the panels.

' .WaZZ studs,

I preferably employ one set of studs, as S for the interior wall form and another set, as -9 for the exterior wall form, and in carrying these wall forms around the corners I preferably make use 'of special interior corner studs '-10 and {exterior corner studs 11-, the inner corners of the interior studs being rabbeted and their edges beveled inwardly, while the outer corners of the exterior studs are rabbeted and their edges beveled outwardly for receiving between them interior and exterior wall panels l2, the edges of which are similarly rabbeted and beveled to permit them to be easily and quickly'placed in operative vposition and removed or -stripped; when their fastening devices hereinafter described are released. V

As previously explained, the lower ends are rabbeted and beveled to' seat snugly upon the upper rabbeted edges of their corresponding wall plates -3 where they are held in place by the bolts l' and keys each stud being provided with a'plupanels 1'2 in and from their operative positions.

spaced relation near their upper ends by concrete spacing sleeves 16- (Figure 15) extending across the intervening space -7-, and of substantially the same length br width as the spacing blocks -'2, each sleeve being provided with a central opening -c-' of angular cross-section'as shown more clearly in Fig. 15 for receiving a bolt -l7* of similar cross-sectionas shown in Fig. 14, said bolt having its opposite ends extending through registering openings in the studs of each pair and provided with hook shaped slots for receiving'the pivotal pins of a pair of eccentriclevers 18, whereby when turned in one direction, their eccentric faces will engage the adjacent faces of the'studs to hold them in operative position, or by releasing the levers they may be withdrawn from their slots in the ends of Y the bolt l7 to enable the studs to be removed. y

The bolts '17' are provided with collars c rigid therewith for engaging the outer ends of the sleeves 16 and inner faces of the outer studs 1l and to thereby assist' in holding the'studs in properly spaced relation when the eccentric levers 18' are tightened; V

ripheral grooves --d-, as shownin Figure- 15, for receiving suitable reinforcing rods (not shown) forthe concrete and holding said. rods in place as the concrete work progresses.

The inner stud sections for the outer wall of the cellar or first story are preferablyerected first or before the erection of the outer studs for the'same wall, andextend from 'fioorto ceiling, or from thefooting strips -3 to the undersideof thefloor forms hereinafter described, said stud sections being spaced a suitable distanceapart along the footing course of each side of the building for receiving between them panel sections 12- of the form'of suchrsize as maybe conveniently handled, it being understood that after the lower ends of the inner stud sections of the outer wall'have been secured in place to the footing .strips 3', they are properly plumbed, or brought 'into parallelism and temporarily held in this relation by stiffening members 23 applied thereto neartheir upper ends to 'remain'i'n place during the erection of the remaining sections of the outer wall of vthe and supporting gthe ,stiifenin member same story; and: M OI LQ TQ we wh l i. may be a progre v ly erec ed b we n t e. nnerian outer form: sections for the same; wall.

The-columm-formniay be temporarily supported in an; nprightor plumb position by ajbrace 2l having one end attached to the upperportion of the column form and itsopposite-lendattached to the lower ortionioffi-gne of the stud sections -8- directly opposite the column, the attaching wall term. and jis provided with, a spacing r. y i

j f'The formifor the column consists of, in

mama

devices of said brace to both the column formand stud section preferably consisting of pins which may be readily inserted through apertured parts of the connected members and quickly removed when desired.

When the inner stud sections 8 and -l0 of the outer wall forms and the upright plates 19 of the column form are erected in the manner described, the girder forms are next placed in position upon the upper ends of said stud sections and plates, each girder form consisting of a pair of opposed sheet metal channel plates 22 arranged endwise vertically with their channels facing each other and-in spaced relation transversely for receiving and supporting a pair of inner wood sections 2T which are also arranged edgewise vertically in transversely spaced relation against the inner faces of the channel sections -2Q- and are provided at their upper ends with out-turned flanges 28 resting upon the upper edges of said channel sections, the space between the lower edges of the wood sections being filled in by an additional wood plate 29 which is held in place by a button -15 similar to those previously described for holding the wall panels in place, except that these buttons are pivoted to the underside of the,

plate -29- to swing in a horizontal plane into and out of engagement with suitable keepers 30 on the lower edges of the channel plates 22 as shown more clearly in Figures 2 and 16.

As previously intimated, portions of the girder plates 22 rest upon seats on the inner faces of the longer plates 19 near the upper ends thereof, and are additionally held in place upon the column forms by clips 31- and keys '32- which are passed through registering apertures in clips and adjacent portions of the longer plates 19 as shown in Figure 16.

The outer ends of the girder plates 22 are supported upon the upper end of one of the stud sections 8, which is directly opposite the column forms and may be additionally held in place by clips on said stud section.

By assembling the parts of the girder in the manner shown forms alengthwise channel'therein openat the top and communicating with the space between the plates of the column form and also with the space be tween the inner and outer stud sections of the wall forms for receiving the concrete for the walls and girders.

The joist forms extend from opposite sides of the girder forms to the inner studs 8 of the outer Wall forms at right angles to the girder and in parallel spaced relation corresponding to the spacing of said stud sections, each joist consisting preferably of a pair of reversely arranged sheet; metal T- pieces 33-, or what is commonly known as metal lumber, having their vertical flanges overlapping and secured to each other and provided at suitable intervals with pendant bolts or threaded studs 34 for receiving buttons l5 and retaining nuts 14 therefor the upper ends of the metal pieces 33 being capped by a wood strip or filler 35 as shown more clearly'in Figure 19.

The metal strips of each joist form are secured at one end to the girder plates 22- by clips 31- and tapered pins 2 which are passed through registering apertures in the clips and adjacent end of the joist sections 33-. The other end of each of the joist sections 3 is supported edgewise upon the upper end of the adjacent stud section 8 and is clamped thereto by a tapered key 5 similar to that previously described for locking the lower ends of the studs to the footing strips 3, except that it is passed through apertured lugs 37- and -38," on the adja cent portions of the metal section 33 and stud -8-, respectively, as shown in Figures 16 and 20.

The end of each joist form which is secured to one of the inner stud sections of the outer wall form is provided with a removable extension 36 having hookshaped attaching members for interlocking engagement with pins et0 on the sides of the metal sections -33 the outer end face of the extension 36- being substantially coincident with the inner face of the adjacent stud when the joist form is assembled thereon to form a substantially unbroken surface along the inner face of said stud section from the footing course to the floor, while the upper face of the same ex tension is disposed in a horizontal plane substantially coincident with that of the upper face of the filling piece 35 and is adapted to overlap upon said filling piece and also upon the upper face of the adjacent-end of the metal strip 33- to form a liquid tight joint therewith. The adjacent end faces of the main body of the strip 33 and extension 36 are beveled downwardly and outwardly, but are normally held together when the parts are assembled by hook-shaped members 39--- on the extension 36 adapted to interlock with pins -4l0 on opposite sides of the adjacent end of the metal strip 33, as shown more clearly in Figures 16, 17 and 18.

The only object in providing the joist form with a separable end section 36 is to enable these forms to be more easily stripped from the concrete after the latter is set.

It will be seen from the foregoing description that the floor forms aresupported entirely by the column forms and inner stud sections 8- and 10-- of the outer wall forms independently of the outer stud sections 9 and 1i, and that these inner stud sections 8- and -10-, together with the inner footing strips -3, girder forms and joist forms constitute a skeleton frame for receiving and supporting the inner panels of the wall forms and also the panels of the floor forms.

The outer stud sections 9-- and --1l-- of the outer wall form are preferably erected directly opposite the inner stud sections -8 and -10- after the latter have been installed and properly braced, and in fact the installation of these outer stud sections may be deferred until the floor forms are placed in operative position, and while it may be preferable to complete the erection of the forms for one story at a time, it is evident that the forms for the several stories, including the floor forms, may be erected before the concreteis poured into the in tervening spaces.

and -10 which face each other, are rabbeted and beveled inwardly to form stop flanges for limiting the inward movement of the panel sections l2 to approximately the vertical plane of the footing strip 3- and stud sections -8- so that the outer faces of those parts when assembled will lie in substantially the same vertical plane where they are held by turning thebuttons ---]r5- across the inner faces of the adjacent portions of the panels as shown more clearly in Figure 4.

These panel sections are preferably made up as units of such size as may be conveniently handled and preferably of a width corresponding to the distance between the stud sections, while the vertical height of each panel is equalto substantially half the height of the story from floor to ceiling, thus requiring in this instance two panels one upon the other to fill each space-between the stud sections, the lower edge of the loweu most panel and upright side edges of both panels being also rabbeted and beveledto cause them to fit snugly againstthe correspoii'ding rabbeted'edges of the footing strip --3 and stud sections, and to thereby form substantially liquid tight joints. The adjacent meeting edges of'both panel sections, which are arranged one upon the other, are also rabbeted and beveled for the same purposeand are held against inward displace ment one upon the other by buttons 15-- siiriilar to those previously described. The

outer footing strip '3 and edges of the outer stud sections 9- and 1 1, which face each other, are also rabbeted and beveled outwardly to receive panels '12- which are similar to the inner panels except that they extend above the level of the lower surface of the floor, but are preferably divided to form two panels for each space between the stud sections, the lower edgeof the may be removed by outward displacement when stripping the forms.

The panel sections, as 4E0, for the floor forms are of substantially the same area as the spaces between the joists and between the joist and outer walls, and are provided with substant ally flat upper surfaces, the

edges thereofadjacent the joists being supported by buttons '15- which are mounted upon the bolts -3l and held in place by the nuts -14, as shown more clearly in Figure 19, in which they are shown as provided with ledges -41 extending under the adjacent edge of the filler strip 35-' to form a liquid tight jointtherewith, while theedges adjacent the outer wallsare preferably supported upon the upper ends of the inner'stud sections 8- and 10- and also upon theupper edges of the inner panel sections 12 being placed in position from below and held in place by the buttons The edges of the floor panel sections ad jacent the girders may be secured in any suitable manner to said glTClGIS to form liquid tight joints therewith.

The forms for the remaining stories may be successively erected infia manner'which is practically a repetition of that previously described for the first story, except that'the" floor forms constitute a support for the' spacing blocks 2' instead of the concrete footing course That is'theconcrete spacmg blocks 2 ceiving and supporting inner= footing strips 3- similar to those previously described as resting 'upon the concrete footing course a re supported upon the upper flat faces ofthe'fioor forms for re determine the thickness of the wallywhile other portions extend horizontally to determine the thickness oft-he floor.

The inner footing strips -3 rest upon the horizontally extending portions, under which COHClltlOIlS the outer panels for the outer wall may he built up continuously one uponthe partition walhthe horizontal portions determining the thickness of the floor and correspond in thickness with the horizontally extending portions of the spacing members 2- for the outer walls, and serve to support additional footing strips 7 3 for the partition forms. 5 ,1

These footing strips, like those previously described as resting upon the footingcourse l, aresecured to the separator blocks by' bolts 4. and wedge keys -5, which may be readily removed when stripping the forms. The partition forms are similar to the outer wall forms in that they are com posed of inner upright studs '8 and outer upright studs -9-, bothof which are secured in transversely spaced relation to the footing strips 3- and rise to points in proximity to the ceiling of the next floor for receiving and supporting intervening panels- 1isimilar to those previously described.

It beam ceilings are iequired,-tli e joist 33- will simply be lowered with a correspouding lowering of the filler plates in which case the adjacent sides of the panel sections, as 4CO, will be extended downwardly a corresponding distance to bring the ledges l1- against *the underside of said filler plates as shown at the upper floor of Figure 1.

In stripping the various parts of the building form after the concrete for the walls. columns. floors and partitions have set. the order of assembly of those parts will be reversed. the panel sections being first removed, then the floor sections. following which the stiffener-s and braces, and then the stud forms and column forms may be rei moved, all of which may be re-used in the erection of forms for other buildings.
