Franklin Foss Attorney, Agent, or F irml-larbaugh and Thomas [5 7 ABSTRACT Two laterally and directionally adjustable supports for shoring and rolling out a formwork intact for reuse in successively pouring concrete floor slabs in a multistory building. Lateral adjustment includes extension brackets having bases mounted on structural columns each carrying a horizontal angle arm that defines a vertical weight-bearing flange and a lateral horizontal clamping flange. Horizontally adjustable support brackets rest on the vertical flanges and have clamping means engaging the clamping flanges to hold tubular support means erect against the vertical flanges in weight-bearing relation. The support brackets telescopically receive screw assemblies through their tubular means for adjustment from below as supported by a nut non-rotatably resting on the tubular means. Each screw assembly includes a roller roll out fixture and a flanged guide shoe fixture telescoping with the roller as supported by an intermediate collar vertically controlled by a winged nut on the screws.

This application is continuation in part of our Application Ser. No. 322,969 filed 1/12/73, now US. Pat. No. 3,815,858.

BACKGROUND OF THE INVENTION:

Heretofore, concrete workform roll-out rollers have been rigidly supported on elements that are spaced laterally a substantial distance from the centerline of support brackets in order to be cleared by the support head of the screw jack when it lowers the formwork for roll-out. Furthermore, not all brackets and rollers are at the same level on the structural columns nor are the rollers necessarily in alignment for roll-out. Also, not all distances between the column and a form beam engaged by the roller are the same. Generally, substantial space is provided between the adjacent workforms that are located on the opposite sides of a column, which space is occupied by narrow secondary forms. These forms drop out or are removed when at least one of the adjacent main forms is lowered sufficiently for roll-out. This generally increases or leaves substantial lateral clearances between the main forms and structural columns in which uncontrolled form beams during roll-out can weave, scar the column, and upon occasion laterally roll off of the roll-out rollers. This generally causes a binding of the forms and incurs delay and extra work and also leads to damage to the forms and materially decreases their longevity if they are knockdown forms for reuse at other building sites.

SUMMARY OF THE INVENTION:

In the present invention, not only is adequate clearance provided between structural columns and formwork for free roll-out, but provision is also made on laterally adjustable beam support shoes for guides to direct the form beams on the rollers, and protect them against derailment. This affords as much column clearance as will be required, or desired, merely by positioning the roll-out rollers and the flanged shoes laterally towards or away from the columns, or both, to align both the shoe and guide for uniform, rectilineal roller support, both laterally and vertically, and the same for the rollers and guides for a free undistorted form rollout. Not only does this prevent roll-offs where the clearances are desired but also increases the ease of roll-out and longevity of forms for repeated use with beams supported against spreading or being cramped, particularly where steel beams are accurately spaced and squared as disclosed in the co-prepared application of Ratcliff, et al, Ser. No. 478,698, filed June 12, 1974.

Although reusable formwork support brackets mounted on the structural columns of a building under construction have been provided that are adjustable as to height for levelling the form and then lowering the formwork for roll-out and reuse, in the present invention they individually are universally adjustable independently, even to angular direction with respect to the vertical plane of the supporting bracket, and collectively are adjustable with respect to their alignment and the spacing of the guides for holding the forms in line and securely in orientation on the roll-out rollers. Accordingly, even with some discrepancy in the base mounting which may not be exactly square to their alignment, the rollers will be brought square to the line of roll-out with little tendency for the forms to roll off of the rollers even where substantial roll-out clearances are providedv Furthermore, once the beams are located on the roll-out brackets, their guided relation is maintained regardless of the height of adjustment of shoe or roller.

In the present invention the opposing supports include simplified easily handled extension brackets each having a base plate which may be releasably secured to a column within wide tolerances and a horizontal L- beam section or bar end-welded thereteo to provide arms approximately extending towards each other in pairs when mounted in place on building columns. A variation of :1 5 horizontally and four inches vertically are tolerable. Vertically oriented tubular support brackets are slidably received on the arms as clamped thereto in a spaced relation predetermined by the spacing of the roll-out beams of a formwork. The tubular supports closely but freely receive externally threaded members of screw assemblies in an axial telescoping erect relationship. Two nuts are carried by each screw. The lower nut non-rotatable engages the support in weight-bearing relation for vertical adjustments by rotating the screw from its lower end. The upper nut is a winged nut which could include carrying an antifriction spacer above it.

The upper end of the screw swivelly supports a roller fixture directly and also a load bearing shoe fixture which non-rotatively telescopes therewith and rests on the collar spacer supported by the winged nut whereby adjustment of the winged nut determines whether the weight of the formwork is borne for rollout or held by the shoes in a fixed position. The relative position of the roller and the shoe remain unchanged when they are moved vertically as a unit by screw rotation. Thus, the shoe can be initially lowered for the roller to be levelled to support the beams of the form without distortion when deposited thereon. The shoes are then raised a predetermined distance therefrom to take the form load when thewinged nuts are advanced a predetermined number of revolutions. Thereby, the roller and shoe fixtures jointly have universal directional orientation as well as a'separate relative vertical adjustment with respect to each other. A workman merely finalizes the major adjustment with an extension wrench from below with substantial savings of time and effort.

Other and further objects and advantages will become apparent from the description and drawings which follow including the ease of fabrication of the embodiment shown; simplicity of operation and servicing; and minimized effort to adjust relative position of parts with minimum friction.

THE PREFERRED EMBODIMENT:

Referring in further detail to the drawings, a concrete structural column 10, of a building that is being built of poured concrete, is shown in FIG. 1 supporting formwork 12 upon which concrete is poured to form the slab 14 of the next floor above. After hardening, another series of structural columns will be formed above as extensions of the lower ones and the formwork as illustrated can be lowered a substantial distance, rolled out intact in a horizontal direction from below, and then, as a flying form, rigidly relocated on supports 27 fastened to extensions of the columns for reuse in forming the next slab 14, etc.

Preferably, the frame of the formwork includes longitudinally disposed parallel I-beams l6'with slings I8 that support cross joists which in turn support plywood form panels 22 as more particluarly described in said Ratcliff, et aI, application. The column 10 is one of many arranged in pairs that are spaced and aligned in parallel rows in a repetitive pattern with each having spaced securement bolts 23 through them with wide tolerances to clamp the base members 26 of the support 27 in place, particularly if the columns are rounded in shape.

Although the support 27 can be made up of steel castings without need for welding, it is illustrated as made in two parts one of which is the extension bracket 28 and the other a support bracket 38. The extension bracket 28 includes a base 26 which has end-welded thereto a length of an angle iron 30 with a deep flange portion 32 thereof disposed vertically for weightbearing purposes and a narrow flange portion 34 disposed horizontally to serve as the stationary part of a clamp 36 (FIG. 2) which adjustably receives a support bracket 38 at any selected position along the flange 32. A stop 35 is welded at the free end of the angle iron 30 to prevent unintentional disassociation of the assembly.

The support bracket 38 is a screw lift 40 which is mounted for adjustment along the flange 32 and includes a T-shaped body portion 42 of two plates 44 and 46 (FIG. 3) welded together at a right angle as at 48 with welded spaced right triangular braces 50 interbracing them. The upright plate 44 rests against the vertical flange 32 and receives on its outer surface the tubular member 50 of the screw lift 40 as offset welded thereto at 51 to provide maximum extension of the screw lift 40 and terminates below the upper end thereof as held structurally in place by suitable squaring braces 52.

Beyond the edge of the horizontal flange 34 the horizontal plate 46 is apertured at 53 to receive bolts 54 therethrough. A pivotal clamping element 54 similarly apertured at 55 inside a fulcrum member 56 welded thereto serves as a jaw 58 for clamping the bracket 38 any place along the bar merely by tightening nuts 57 on the bolts 54 to draw the clamp element 58 against the bottom face of the horizontal flange 34. The nuts are accessible from below for actuation by a socket power wrench for individual spot adjustn'ients.

The screw jack assembly 60, including a coarse threaded screw 62, can be slipped into place in the tubular member 50 either before or after the extension bracket 28 has been positioned and carries two nuts 64 and 66 above the tubular members 50. Preferably the screw 62 is a sleeve more than twice the length of the tube 50 and is provided at its lower end with a wrenching member 68. It can be machined or formed square, or a cast member can be used, but is illustrated as a hex head nut 68 welded thereto at 70 for engagement by a crank or power wrench (not shown) for rotating it. The opening (not shown) through the nut 68 drains the interior of the screw 62 to avoid dangers of water collection and freeze ups.

The upper end of the screw 62 removably supports a shoe fixture 72 and a roller fixture 74 rotatively which telescope with each other on the screw. For this purpose the screw 62 internally removes the vertical spindle 76 of the roller fixture 74 that has a yoke 78 secured thereto whose arms 80 carry an axle 81 that journals the roller 82. The bight of the yoke 78 rests rotatively on the flattened upper end 83 of the screw.

The shoe fixture 72 is load bearing and has a collar 84 loosely received externally on the upper end of the screw 62 as rotatively and adjustably supported in axial telescoping relationship by the winged nut 64 threaded on the screw adjacent to its upper end. The collar 84 carries a yoke 78 telescoping laterally over the roller fixture 74 and terminating in diverging flat arms 86 that define a flat head 87 to engage the beam 16 of the formwork 12. The edges of the yoke 78 are reinforced by contour cut plates 88 welded thereto and define a well 89 into which the roller fixture can non-rotatively telescope to a level below the head 87. Upon at least one side a cut plate 88 extends above the highest adjustment point of the roller 82 to provide a flange 88A resting laterally against the base flange 17 (FIG. 1) of the formwork beam 16. The flange receives the formwork beam 16 for geometric alignment once they overlap in height, and the beam in turn through the flange 88A thereby nonrotatively supports the shoe fixture 72 and the roller fixture 74 against rotation relative to the support bracket 38. This non-rotative engagement of the flange 88A with the beam also prevents swivel rotation of both the shoe fixture 72 and the roller fixture 82 on top of the screw regardless of which one is actually in contact with the beam 16. The relative support adjustment between the shoe 72 and roller 82 is not disturbed when bodily raising and lowering the two fixtures as a unit as when turning the screw 62 in the cam nut 66 for gross or fine adjustment levels.

Thus, the roller and shoe fixtures are rotatable on top of the screw 62 and respond to universal directional orientation in a horizontal plane to square-engage a formwork beam when oriented. Adjustment of the winged nut 64 on the screw 62 raises or lowers one fixture with respect to the other without relative rotation between them and the screw 62 bodily raises and lowers them as a unit in their adjusted relation by being rotated in the non-rotative nut 66. Accordingly, the roller 82 is freely orientable to accommodate the direction of endwise movement of the beam, and also to be readily repaired if damage is incurred. Either the roller or head, or both. can be removed and replaced by merely lifting either or both members from the upper end of the screw sleeve.

As noted, the tubular member 50 is shorter than the plate 44 preferably at both ends by a distance approximately the height of the nut 66 and the space between the plate 44 and the exterior surface of the screw 62 is less than the major diameter of the hex wrenching contour nut 68. Thereby, when the screw jack assembly is lowered into place on the top of the tubular member 50, any minor diameter flat portion of the hex contour of the nut 68 will be disposed next to the plate 44 (FIG. 4) and will be thereby held against rotation when the nut 68 is in weight-bearing relation on the tube 50.

The load of the formwork beam 16 is carried by the nut 68 from the screw 62 regardless of which fixture is the highest. If the roller 82 is the highest the load is transmitted directly from the roller fixture 74 to the upper end 83 of the screw. If the shoe fixture is the highest, the load is transmitted by the head 87 through the collar 84 and the winged nut 64 to the screw 62.

With the present invention the relative installation heights of the respective fixtures 28 are not critically significant regardingvariations in heights between respective sets of mounting bolts 24' since the roller and head assembly units can be levelled easily throughout the building area bya crank or power wrench (not shown) engaging the hex headed lower ends 68 of the screws 62 and adjusted, if need be, to transit sightings.

During installation the preassembled formwork is preferably lowered intact onto levelled roller fixtures with the flanges 88A preferably located remote from the columns. Thereby, the fixtures 72 and 74 are disposed properly under and in alignment with the beam 16 and the forms can be rolled into place in tight engagement with one another. Thereupon, the formwork beams 16 can then be raised by the shoe fixtures 72 to their final height by operation of the winged nuts 64 ready for pouring.

After the concrete slab 14 is poured and hardens sufficiently, the screws 62 are progressively retracted downwardly as turned from below'until the formwork 12 drops free of the slab. and, is low enough to roll out. There'upon. the winged nuts 64 are retracted to expose the roller fixtures 74 to contact with the formwork beams and with the guide flanges 88A engaging the sides of the beams, the rollers are held oriented in the roll-out direction for the rollout.'
