Application July 14, 1950; Serial No. 173,788

2 Claims. 1

This invention relates to improvements in forms employed in pouring concrete walls and is a continuation-in-part of my copending ap-- plication, Serial No. 789,021, now U. S.v Patent 2,523,131.

In the above identified application. Ihaverdisclosed certain novel ribbed metal plates which may be secured together to provide a formv of anydesired length. They present invention relates to somewhat similar plates or panels, but the means for securing them together differs.

One of the objects of the invention is to provide a novel bar construction which secures ad- J'acent panels together.

Another object is to draw edges of the adjacent panels together when the bar construction is applied thereto.

Another object is to provide a plurality of. standard width panelsand panels of fractional width thereof. so that a wall of any desired length may be'poured.

A further objectis tofemploy the principals of the invention to a slip: form.

Still further objects, advantages, and salient features will become moreapparent from aconsideration. of the .description .to follow, the appended claims, and the accompanying drawing, in which:

Figure 1 is a side elevation of one standard panel shownsecured to adjacentpanels, portions being brokenaway';

Figure 2. is a. similar view showingafractional width panel interposed betweenadjacent panels;

Figure 6 is an enl'argedzsection taken'on' line 6--6, Figurei5;

Figure 7 is a fragmentary side elevation taken in the direction of arrow 1, Figure 6;

Figure 8 is a section taken on line 8-8, Figure Figure 9 is an enlarged section-taken on line 9-9, Figure 8;

Figure 10 is an enlarged section taken on.line l--I0, Figure Figure 11 is a section taken on line I|ll, Figure Figure 12 is a section takenv on line l2--l2, Figure 11;

Figure13 is a fragmentary end. elevation irrthe direction of arrow [3, Figure 6;..and

Figure 14 is an enlarged section taken on. line [4-44, Figure 5.

Referring in detail to the drawing, and particularly Figures 1 to l, a panel comprises a fiat sheet of metal 2! having a plurality of dia- .feet' high with the ribs disposed at 45 to its vertical edges.

A pair of T-shaped bars 3|, '32'overlie the joint between panel 20 and adjacent panel 20a. Bar 3I'is provided with projecting taper pins 33,34 (see Figure 3) near its lower end which engage inapertures '36, near the ends of adjacent ribs 28a, 26, respectively. An identical pair of pins3'l, 38 engage in'siinilar apertures'in ribs 21a, 25, respectively. All of these pins have a tapered portion and a-cylindrical body portion and are so spaced relative to the apertures in the ribs that the tapered portions wedgethe edges of adjacent panels together when the bar is drawn toward the ribs-thefinal position being as shown in Figure 3 with the cylindrical portions fitting the apertures in the ribs. The upper T-bar 32 is identical to" lower bar 3| but'disposed in invertedposition, pins 39, 40 corresponding to pins 33, 34,and pins 4|, "corresponding to pins 31, 38. T- bars 43, 44 are identical to the bars just described-these bars securing panel 20b to panel 20 in'the same manner described for bars3l, 32.

In setting up the panels to pour awall they are temporarily supported in any suitable manner and anchors 45 are disposed therebetween at points 4.6, 41, 48 and corresponding points betweenpanels 20 and 20b. These anchors are of a length the same thickness as the concrete wall to be poured and threaded on opposite ends for receiving'tie bolts. 50,. one end of the anchor and the'panel of one side of the form being shown in Figures. 3 and 4. .Tie bolts Snare inserted-through the flanges 5| of the T-bars at points 46, 41 and 48, the flange 5120f the T-bar being cut away at point46to receive a tie bolt50, an aperture 52 beingprovided inthe base of the T-bar through which the'bolt-extends, suitable juxtaposed semicircular holes being provided in the ribs and plates:attheir juncture edges through which the tie-boltextends. A U-shaped clamp 53 straddles the flange of the T-bar providing a bearing upon which the headof the bolt may turn, the clamp alsoadd-ingstrength to the construction. The upper end of T-bar 3| is provided with a semicircular hole-and a similarcut away flan'ge'for receiving a'tie bolt at this point, a similar U- shaped clamp 53 being provided which bears on the ends of T-bars SI and 32. The construction at point 48 is the same as at point 46 and the same construction is employed between panels 20 and 20b.

It will now be apparent that as tie bolts 50 are drawn into anchors 45 the taper pins will first wedge adjacent panels toward each other and when the panels are finally drawn against the anchors the pins will appear as shown in Figure 3 with the edges between panels abutting.

Since walls are not always of a length which is an even multiple of panel width, it is necessary to provide fractional width panels which may be attached to standard width panels, and hence a set of panels will include the former. In Figure 2 a sixteen-inch anel 200 is illustrated. This panel is identical to the first sixteen inches of panel 20 from'its, left edge towards its right edge, but differs in that auxiliary short ribs 54 are secured thereto. These ribs are provided with apertures like 35 for receiving the taper pins on T-bars 55, 56, the later being identical to the other T-bars. With a twenty-four inch width panel the auxiliary ribs are not required, since the normal ribs on a panel of this width will terminate in alignment with the continuing ribs of the next standard panel. It is apparent that any other suitable fractional width panels may be employed in the set.

In Figures 6 to 13 another application of the invention is illustrated wherein a so-called slip form is employed. The panels in this case are similar to the ones previously described, but no tie bolts are employed. The taper pins 33a, 34a are disposed on the T-bars in the same angular relationship as taper pins 33, 34 previously described but are bent upwardly and engage in apertures, such as 35a, in the sides of the ribs. When a T-bar is moved vertically, adjacent panels are drawn together by each set of adjacent taper pins in the same manner described for Figures 1 to 4.

Aremovable channel shaped spacer bar 60,

having notches 61 near its ends, extends between notch 65 in reinforcing plates 66 welded tothe sides of the flange of T-bar 63. The other bight has pivoted thereon a cam 61. It will be apparent that when the lower ends of the panels are disposed as shown in Figure 6, on the sides of a previous poured portion of a concrete wall 68 they may be clamped thereto by applying spacer bar so and moving cam 61 to the position shown.

The various panels of the form may be supported by a plurality of rods 69 having hooks at their upper ends, the latter engagin a bar 1| which is supported by rods 12 which join at their upper ends on the hook of a crane (notshown).

The lower end of each rod 69 has an eye 73= which engages a cross pin 14 which extends between the links 75, 16 of a toggle device. A lug I1 is provided on each side of link 16 which engages ends '18 of link to limit upward relative movement of the links. In the operation of the construction just described, the form is lowered into place on wall 68, cam 61 being in its disengaged position, that is, with lever 19 thereon in a horizontal position. The toggle device will be straight at this time and the lower ends of the panels spread apart a distance greater than the width of the concrete wall 68. The lower edges are lowered onto any suitable support such as bars which prevent downward movement of the form. Rods 69 are then lowered breaking the toggle links to the position shown in Figure 6 after which lever 19 is moved to the position shown which draws the lower ends of the panels toward each other, pivoting about slots 6 I. The wall is then poured, and after it has set, cam 61 is moved to unclamped position and bars 60 are removed. Upward movement of rods 69 straighten the toggles, breaking the panels away from the wall. After -the suction has been broken and the panels thereby loosed from the wall, rods 69 are lowered and bars 60 reapplied. Vertical movement of the rods again straighten the toggles breaking the lower edges of the panels away from the walls. ther: vertical movement of rods 69 removes the panels from the poured wall. It is to be understood that rods 69, cams 61, and bars 60 may be manipulated in various manners and sequences and the particular operation just described is only one of the several manners of manipulation.

Having described the invention, what I claim as new is:

1. A form for use in molding concrete walls, comprising, a pair of plates abutting along juxtaposed edges thereof, at least two spaced diagonal ribs on each plate, the ribs on one plate being in axial alignment with the corresponding ribs on the other plate and the ends of the ribs at the line of juncture between the plates being juxtaposed, a bar overlying said edges and the ends of all ribs, and wedging means on the bar engaging adjacent abutting ribs on adjacent plates for securing the plates together, said securing means comprising pins on the bar engageable in apertures in the ribs.

2. A form for use in molding concrete walls, comprising, a pair of plates abutting along juxtaposed edges thereof, at least two spaced diagonal ribs on each plate, the ribs on one plate being in axial alignment with the corresponding ribs on the other plate and the ends of the ribs at the line of juncture between the plates being juxtaposed, a bar overlying said edges and the ends of all ribs, and wedging means on the bar engaging adjacent abutting ribs on adjacent plates for securing the plates together, said securing means comprisin pins on the bar engageable in apertures in the ribs, said pins being tapered to draw the plates together upon relative movement between the bar and plates.
