INVENTOR latented June 7, 1932 Unites STAT-ES WILLIAM G. VENARD, OF LOS AN GELES, CALIFORNIA FOR-M FOR BUILDING COLUMNS ANDBEAMS 7 Application filed August 6, 1930. Serial No. 473,380.

This invention relates to improvements in building forms and particularly to forms'tor making beams and columns of buildings in the course of erection, especially plastic columns and beams.

One of the objects of the present invention to provide a simple, eficient and inexpensive concrete beam and column building form designed along lines that assures the saving of both time and labor.

A further purpose of this invention is to provide beam and column forms constructed of extensible, adjustable parts so that the size of the form enclosure may be'varied at will.

Another object thereof is to provide beam or column forms built up vertically and transversely from a series of replaceable andinterchangeable metal plates so arranged and constructed as to avoid the necessity of the form having to be cutto predetermined.

widths and sizes, and permitting a number of metal plates to be set up quickly for the same purpose. V

A further object of this invention is to pro vide a series of interchangeable, adjustable battens or bracing members designed to be lengthened or reduced in length accordingly as the width of the form walls vary.

A still further object of this invention is to provide a beam form extension designed to be built onto and removably connected to the upper end of the column form to allow the beam and column to be built from a unit form enclosure.

Another object of this invention is to provide a novel form of means for bracing the coinciding edges of superimposed metal plates of a form wall structureto assure prop' er clamping pressure being exerted along these marginal parts of sectional walls, and to this end each batten or bracing unit consists of two parts, one part telescoping in the other part, and each part consists of two elongated parallel sills with cross arms interconnecting them into a rigid whole. In the spaces between the sills of the wider parts of each bracing unit are located channel-shaped metal rests, their edges of the two arms thereof overlying the coinciding edges of meeting wall plates in a plane at right angles to the sills of the brace members which overlie these same surfaces longitudinally. A series of T-shaped bolts are employed in a manner that theircross heads may directly overlie and bear upon the opposing sills of the narrow parts of each brace member, which are slidably adjustable in the wider parts of the same brace member, while other of these bolts have their cross heads overlying the channel shaped metal rests since they cannot directly span the sills of the wider brace parts. The shanks of the T-shaped bolts are screw-threaded and they are tapped into the coinciding edges of the plates with thumb nuts engaged upon their inner ends to clamp the heads of these bolts and draw the battens or brace members under pressure upon these plates.

I'also provide novel means for locking the corner-arranged brace members or unit-s one to the other under mechanical frictional pressure for the purpose of assuring that the corners of, the form will be held in rigid rela tionship and against buckling.

lVith the'above and other objects in View my invention consists in the combination, arrangement and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims. 80

In thedrawings any number ofmetal. thin. plates .-are--. employed to-produce the -form: for

making apost or column or beam It is pre-,

ferredrthat the several :wallsections to-make up this form suchasthe plates FA, B C, etc. be rightangular in.cross-sectiomeach havlng thelwalls 10rand. 11.. 111': Figurel2 it is shown. how these rightangular aplates overlie one up-H on the marginal .edge of. .tllBOtllBl so as to be adjustableto vary. the widtlrof the wall of the form which they will serve "to. make. Figure l lshows flanges 12,.13 -formed upon the. =cor-n er. parts of each. rightangular plate A' B; CjandDf respectively, the terminals beyonduthe, adj acent..extre1ne end ofthe flange 12, so these parts are shoulderedione against the other. Here the flanges serveto reinforce the rightangular plates giving .themmore strength. and. durability.

Figure '14: shows how these plates are arrangedto produce a rectangular enclosure for building a concrete column or post therein; Since the sheet metal plates will be of inapprociable thickness their overlap will hardly interfere with the flush continuation of. eachiside {of the -comple'ted:column.

In Figure 11 :the "method "of securing "the. form platesabout Wall: posts is shown. where columns,..-..I-Iere it is .obser-vedthat the walls '11 of each rightangular plate may be formed with a rightangular flange at the end opposite to, and parallel with the wall 10 of each plate. The wall-making plates will have their inner marginal portions overlapping the wall posts 18 while the flanges 19 will overlap these marginal portions of the wall plates 20. Otherwise :therwalls 10 of both plates will adjustably overlap so as to provide one wall and part of rightangular walls of the cohunn.

The. rectangulamenclosures thus produced will be caused to build up a vertical structure and thiswill 'orunay be done by setting the lower edges of upper plates upon the upper edges of lower plates to produce a flush wall :-as shownz-in Figure 1, where A and T represent the walls .-as they are-superimposed and where 14 designates the coinciding edges of these superimposed plates. In order to hold the superimposed walls of the proposed column form at any "height-where placed vertically it .is designeduto employ; bracing membersior units .in-the form of battens now to-bedescribeda In Figure 1 it will be seen-:that each batten or bracing unit consistsof two-parts,'one part being narrowerthan the-other and telescoping adj ustablyin-the other part. Each part is. similarly constructed as follows. wider part of the-adjustablebatten consists of the-elongated spacedapart

parallel sills

21, 22 with-the intervening-space 26, the cross bars 23 -.connecting;.these sills together. The

narrower apart .of the batten.-.consists also of paralleli spaced sills24, 25, withthe inter-J vening;s pace-.27, andthe :cross bars 28 connecting the sills in. a whole; The batten parts will overlie the marginal coincidingvportions or edgeswof..the-plates A.and TuIIl such a lIlHllIIQl-ztllfit the longitudinalsills 21,124 of the adj ustable parts :of thebatten will overlap plate-A.-while the sills 22, of these same hold! the :ba-ttens eundernnechanicali pressure against plates-A .and :T.the following means is employed.

sills

24, 25 of the narrower batten section but not wide enough to bridge the

sills

21, 22 of the wider part, hence the necessity of using the rests to make them provide a rigid backing for the cross heads 32' of the bolts to engage in their function of drawing the battens against the plates A and T etc.

- In Figure 3 it will be seen that the coinciding edges of plates A and Tare formed with bolt-hole recesses and 16 respectively, designed, when these plates are arranged in superimposed relation, to provide bolt holes 17, so after the cross-heads of the bolts overlie the sills 24, and the tops 29 of the rests, the bolts will pass thru these bolt holes 17 and project beyond the opposite faces of the plates A and T etc. Thumb nuts .36 may now be screwed home upon the screw-threaded terminals of these bolts, and clamp the battens against the plates. With all parts thus arranged, the nuts could be loosened sufliciently to allow the batten parts to be moved in and out one relatively to the other to be made coextensive with the width of the form wall plates.

In order to apply suitable mechanical pressure against the corners of the form wall plates whereby they are interlocked at these points rigidly and against buckling or collapsation I employ means to lock the battens that are arranged at right angles, at the corners of the form, together. For this purpose a handle 37 formed with an elongated slot (if desired to allow clearance against the bolt 34 that might project therethrough is desired) is provided, which has its inner end 3764 pivoted upon a pin 38, mounted operatively in the

sills

24, 25 of the batten section. This handle may thus be swung inwardly in the recess 27 of this batten section as shown in Figure 10 in dotted lines, the purpose in doing so being to actuate a saddle member now to be described.

The saddle locking member is composed of two

parallel arms

40, 41 pivoted upon a pin 39 connected to the lever 37 at its inner end,

while another locking pin 42 is connected to the free ends of

arms

40, 41 so as to rigidly span and connect the same. The ends of the

sills

24, 25 of the batten shown in end elevation in Figure 1 are provided with a corner notch shown at 43 in Figure 10, and in this notch the pin 42 may extend when the handle is in dotted line position shown in Figure 10. It will now be seen that guide 56 secured rigidly to the bottom limits the back movement of lever handle 37, and as the handle moves backwardly from dotted line position to full line position shown in Figure 10 the arms 55 40, 41 of the saddle piece are drawn back Thus it will bewardly sufliciently to force the pin 42 into recess 43, and to exert a pressure upon the batten shown endwise in Figure 1, effective to lock this batten to the batten shown overlapping form plates A and T in Figure 1. In this manner it is assured that the corner marginal edges of the right angularly dis-- posed form walls will remain rigidly in proper place. x 1

It may be desired to provide beam-making attachment to the column forms so'that the overhead horizontal beam may be molded at the same time with the supporting columns or posts therefor. For this purpose a specially constructed form is furnished shown particularly in'Figure 8. Here there is disclosed a channel-shaped member composed of the trapezoidal-shaped parallel walls 46,and' 47 and the inclining bottom plate orwall 45, there being an outturned right-angular flange 48 and 49 formed respectively upon the

walls

46, 47 of this beamforming mem-- Figure 6 may overlie the edges of portions- 444 of the form wall plate 44, and nowfasteners 53 will secure flanges to this wall. The use of the

flanges

49, 50 is optional. In this way the beam-making form will permit the beam and column to be molded in one continuous operation.

I also providean efiective means of blowing or sweeping out dirt, and debris that may accumulate in the completed form and for this purpose I form a hole 52. in the bottom of any form plate, and a closure plate 55 having a handle 56 will be slidably and frictionally guided inthe guide tracks 54 formed integrally upon the opposing edges of this recess or hole 52. In this way when the closure plate is raised access is given into the interior of the form whereby a hose may sprinkle water into the form to wash away dirt and similar or foreign particles. or the dirt may be removed from this hole in any other effective manner;

' v I do not int-end to limit myself to the exact details of construction but'aim to cover all variations falling within the purview of the appended claims.
