' rThis invention relates tojconcrete molding 'apparatusand more particularly to apparatus'for the finoldingof poured concrete Walls, loors, partitions and other like structures.

'15L An .object of theinvention ist to 'provide Y molding :apparatus designed to enable the pouring of hollow orfdouble'concretel Walls, Y floors, partitions and otherlike structures.-

According to the'inventiomuse is made of le? molds spaced apart andrigidly'V held inv such spaced relation until the concrete 'poured in a o. the molds has become -sufficiently hardenedto i permitfthe `removal thereof."` Use is made in g the invention ofperma'nent spacing and reino' 15 forcing members andalso of y'covered `bracing I members applieda-fter'the molds havebeen y removed.' 1 A .y ..1

11nv carrying outlthefinventiomuse ismade of a lplurality of 'plates 1 0 which may be ofe Vsheet-metal ofthedesired thickness, length Y "'O Iandbrea'dth.l As ybefore stated, 'theinvention is especially'applicable to the formation of Walls, ioors, ypartitions andl other like structures, but, for the sake'of brevity, such structures are hereinafterftermed Walls, and itis to be'understood that the use of such 55` termin the specification and" claims is not to be *consideredya limitation ofthe invention. On one/side of each ofthe plates 10 is `secured'ajpla'te 11 which may be either a corrugated plate or anyl other deformed plate, 60 but, forfthe purposes of illustration, such plates areherein illustrated as corrugated. These plates' may bie-secured 'to the plates 10 in Y any desiredmanner such asby spot Welding 0rby anyother suitable means. f

' In the practice of theinvention, use is madel offafpluralityof spacing and reinforcing yokes 12 preferablycorrugated as shown andy having-i'flangedl ends 13 and an opening 111 asillu'strated.' Use is also made of a number of rings '15 and ay plurality of sleeves 16.A Rings 15 and sleeves 16 are so constructedk as to permit contraction radially whereby they' t A may bekrexnovedffrom'tlie hardened concrete ture With the molding apparatus remove/CL',V spacing and insulating 'memf each oflthese membersoverlap and the inner f edge of each -is bent back upon itself to proat the proper time during the process of Wall; formation. lFonthis purpose, the edges of videv a recess forfthereception of a suitable tool'r'for contracting the member.'v A num-'30 berrof'lZ-bz'x-r's'l' and'angle bars or wales 18 or other suitable support are utilized in the invention in ythemanner to be hereinafter" explained in detail.

Having described thel component partsis utilized in carrying out my invention, the' operation' anduse'of'the same is as follows. A of'one of ther number 'ofthe-'plates 1()l having the corrugated backing llare placed in position as'indicate'din-Figs.v 1 i,and 3. In order that the plates ybetweeny which the concrete is to be poured may-be spaced apart, the yokes 12 are so positioned that' the flanges 13 thereof rest against one of the plates 10. At the 'same' time, ythesleevesor collars 16 are so positionedas to extend 'throughthe openings 14 inthe yokes 12. To further accomplish the' purposes of spacing, the rings 15 are placed between those portionsof the yokes having thefopenings 14 therein and the plate l0 opposite lthe plate against which the flanges 13 rest. A suitable bolt 20 passing through an opening in one of the wales 1,8 and having its head' resting thereagainst passes through openings in the plates and 11 in such a manner as to be completely encircled by the collar 16,. The opposite end of bolt 2O passes through a similar Wale 18 and ainut 21 Ais employed for securely holding the various parts in their correct position. Y

Since it is desired that the'- wallsY to :be formed shall have a space therebetween, use is made of the Z-bars 17 havinga number of openings 22 spaced at intervals along one of the flanges thereof.v Such bars are spaced between the inner plates 11 in lsuch a manner that the openings 22 rest over the; bolt 20 to permit the flat portionof the Z-barl to seat onl the bolt. When adjusted as shownin the drawings, these' yZ-barsserveto space the renecessary to hold all ofthe parts firmly.A con- .crete ,75 maybe .pouredfinto thegspacebe- Itween the respective-.plates 10.'.` Afterthe concretehas become sufficiently hardened, it is.L ,desirablevv thatV the y plates be removed for, furthervuse. To accomplish this,-advantage is taken ofthe deformed or corrugatedfplates 11 which arespaced apart by the bars 17..

Due to these corrugations, a suitable, tool may be utilized forfdislodgiug the barsl? as illustrated in Fig. 1 topermittheir-removalf-yAny desired tool may' be'usedf forv .-this'purpose, the only requirements'loeing.

l that the tool'be so shaped as to pass between one of the flanges of the Z bar and-adepres# l sion inthe corrugated platell.-rr

/Having removed Z-bars17, the boltsQ()I Vwithdrawm permitting the, removal of plates 10 with their' accompanying'plates 11.vv Since both the rings and the sleeves 16 are-capa ble of being `contractedradially, `a suitable tool may be utilized. for j contracting kthese the concrete.

ings in the concretewhich maybe used; for

the :reception of'a bolt. 25. 'fon permanently holding the wallsA in-spacedIrelation. As

shownin Fig. 2, the head offfthe bolt ,25 rest-s against one oftheyokes 12 while the' nut 26v on the otherend thereof rests against a cor-V responding yoke.v In .order thatthe two sections of concrete may be permanently held in spaced relation and furtherin order fto provide a more perfect insulation, Yuse is madevv of'the following arrangement. VBefore the' permanent bolts 25Lare placed'in positionav number of. continuous spacing strips 'exi tending from top to bottom ofthe structure and ofv anydesired width and thickness are` ,placedv in position. yThestrips are preferspective pairs ofplates from each other. A Having tightened the nut 21 to the extentk "dividingwall of extent equal tov that of the concrete walls.' .These boards for the sake of convenience may also be provided before installationfwith' holesv for the passage of bolts 25. For the purpose of providing a continuous air passage hetweenthe respective layerV of composition boards a portion of .each

of thev spacing strips 50: is cutaway asv indi.-

catedY at 52, The ,airVV passage so pro-duced serve to better insulate the structure than has been found to'be true with an arrangement consisting of a'number of-separate airjcliambers., After the bolt 25 has'been lplaced in positiomrthe remainder of the opening furv nishedbythe withdrawal of rings 1 5 may be filledl with Vconcrete to preserve the continuity:

of surfaceof the wall; y e

l In theevent it is Vfound undesirable to make use of permanent bolts the embodiment illustratedin Figs'. 9`an'd 10 may be Vused especially for, light structures. This -a`rrangement; is composed .of Jflat platesf 10 wand deformed plates 11 as vin'thestructure previously described. Injthis structure, parts corresponding jto vthose v4hereinbefore described are given thesame reference characl tersfwith the Yaddition of a primeto each numerallnstead of the 'bolts 20, use V'is v made ofirelatively thin metallic tie bars 60 providedlwith a numberv of holes for the receptionfof pins lIn order that the sections 0f forms 10. ywith their deformedplates 11 may be connected together each edge of the deformed plates 11 is bent as indicated at 61 'whereby a spline 62 may be insertedbetween the'bent fportion 61andplate 10. Splines 62 are ofthe ysame length as the plateslO and are provided with upset portions 63V of thickness equal to that oflplatesl 10-.' f The i splines and their upsets are recessed atinter-j valsy toaccomniodate the tie barsr60, ysuch recesseslfextending inwardly'from oneedge lthereof to such a distance that therecesses in the upsets arev of 'depth approximately equal. tothe thickness ofthe tiefbars.

Beforegthe formsare assembledfor use it has beenjfound .advisable to insert pins/64 and 65 in holes extending through the tie bars.


ence` to this that the edges of the upper forms jand 11l rest substantially lagainst the tie `barsf60. The. lower .form 10 may then'be positioned and held in place by permitting the previously free edgesfofthesplines to slide Yunder the shoulders 61 ofthese forms until the edges of forms l0 closely approach the edges of upsets 63- Thus'the openings l between the edgesv of the forms l0 is closed by splines 62 and their upsets 63. Z-bar's 17 arey placed as shown to properly space the VVpairs of forms while wales 18 having apertures therein yare placed against the outer' formsll and held in place byfpins66. Concrete may then be poured intothe forms andr permitted to harden suiliciently for there` moval of the forms. a After the forms have been'removed the protruding yportions of the tie bars 60 may be broken oi, such procedure vbeing facilitated Vby Vpreviously scoring or l otherwisewealeningl the bar at the points ina dicated'by dotted lines 67 vIf'so desired'the 'pins 64 may be removed andthe. openings lett thereby illed with concrete to preserve the continuity of surface of they walls. Since the' tie bars remain in the concrete andare i fp'revented from being withdrawn in either div' rection by pins 65, they serve to hold the walls properly permanently spaced." If it isdesired suitable insulating material may be inf sertedbetween the walls in any desired man- `ner-x@ f It isf to be understood that the present in'- vention vis not to be limitedbythe illustrated embodiments but is to be limited only to such structures-and yarrangements as are defined by the following claims.
