No. 609,563 Int. Cl. E04g 17/16, 11/20 U.S. Cl. 249--219 4 Claims ABSTRACT OF THE DISCLOSURE Brackets for supporting form plates for pouring circular walled concrete structures and which provide for movement upward on previously poured wall sections to position the form plates for pouring the next layer or section. The brackets are arranged to slide directly against a previously poured section and to be secured thereto by nuts on bolts anchored in the previously poured section.
BACKGROUND OF THE INVENTION In the construction of circular cooling tower walls of poured concrete, and similar structures it has been the practice to use form plates or arcuate forms which were raised after the pouring and setting of each layer. The invention relates to a supportnig and adjusting means for form plates which are raised after the pouring of each layer and a bracket therefor which is of simple construction and easy to adjust and to secure relatively to bolts arranged in vertical rows in previously poured layers of concrete.
SUMMARY OF THE INVENTION An object is to provide such a bracket which can be supported directly from a series of bolts which extend from the previously iinished wall in a vertical line and preferably which slide directly against the finished wall so that they may be bolted thereto by nuts on the bolts.
Another object is to provide such a bracket comprising a lower channel-like portion with an elongated slot therein through which the bolts in the finished portion of the wall project, a laterally and outwardly extending intermediate portion and an upper post member extending from the outer end of the intermediate portion and spaced from the form plates, together with means on the post member for adjustably supporting the adjacent form plates and also opposing form plates.

FIG. 13 is an enlarged view of a portion of FIG. 4; and
ice
FIG. 14 is an enlarged fragmentary section similar to FIG. 6 showing a form of supporting bolt in more detail.
Although there is herein shown and described a preferred form of the invention, it is to bel understood that this is not intended to limit the invention to the particular form and arrangement shown. The scope of the invention is pointed out in the appended claims.
As shown in the drawings, the invention is applied to a concretewall W which is generally multi-sided or somewhat annular in shape, the side W' being referred to as the inner side of the Wall and the side W" as the outer side of the wall. A form plate supporting bracket indicated generally at 10 is positioned against the outer side of the wall and is arranged vertically thereof so that it may be secured to the wall by means of nuts on the outer ends of a series of bolt devices B which extend through the lower or hardened portion of the wall and are arranged in vertical lines spaced apart generally as shown in FIG. 2, so that an outer bracket 10" is associated with one vertical line of bolts, whereas an adjacent inner bracket 10 is associated with an adjacent line of bolts.
As shown best in FIGS. l and 10, the preferred form of form plate supporting bracket comprises a lower channel-like member 20 having a central slot 21 therein, an intermediate, horizontally and outwardly extending portion 22, and an upper post member 23 secured at its lower end to the outer end of the intermediate portion 22 and extending upwardly at a slight angle from the vertical and spaced outwardly from the adjacent form plate structure 24 hereinafter more fully described.
As seen best in iFIG. 7, the channel-like member 20 is formed from a pair of opposed angle members 25 suitably welded to elongated plates 25. These angleplate elements are secured together in the arrangement shown by means of an upper transverse U-shaped member 26 and a lower U-shaped member 27, both welded thereto so as to form a rigid structure. The intermediate horizontally extending portion 22, as shown in FIG. 6, con sists of a pair of plate members 28 and 29 having ends 30 and 31 welded to the plates 25 and ends 32 and 33 welded to the post member 23. The post member 23"is in the form of a relatively square tube.
The parts 20, 22 and 23, which are suitably welded together, form what may be referred to as a stiff-back and constitute the main portion of the form plate supporting bracket. As mentioned hereinbefore, the channellike member 20 is adapted to be clamped directly against the outer surface of the wall Wl by means of nuts 34 on the bolt devices B as shown in FIGS. 6 and 10.
In the form shown, form plates 24 for the outside surface of the next section of the wall W, and which may be made of plywood sheets 35 of appropriate size, are provided with horizontally extending reinforcing member 36 sometimes referred to as whalers. The members 36, which may be of wood, are suitably secured to the sheets 35 so as to form unitary form plates 24, the outer such form plates, as shown in FIG. 1, having their lower ends extending slightly below the upper end of the linished wall at 37. An opposing inner form plate of similar construction is shown at 40.
As shown best in FIG. 2, bracket 10" is located on the outside of the wall W for supporting the form plates 24. For this purpose the form plate supporting brackets are provided with an outer, vertically extending channel-like member or head 42 and an opposed or inner vertically extending head 43, the form of these heads being shown 3 best in FIG. 4. The head 42 comprises a channel 44 and angles 45 and 46 welded to the opposite sides of the channel and having portions in a common plane adapted to engage the adjacent ends of plywood sheets 35 of the form plates 24. Screw threaded rods or bolts 38 and 39 are welded to the angles 45 and 46, respectively, and extend horizontally therefrom as shown in FIGS. 4 and 13, and through openings in the form of slots 50 (FIG. 12) in angle members 51 and 52 secured respectively to the top members 36 of each form plate. Suitable nuts 53 are provided on the threaded rods 38 and 39 for the purpose of clamping the form plates against the angles 45 and 46.
The outer head 42 formed principally by the members 44, 45 and 46, is provided with a horizontal plate 54 adjacent its upper end, and an L-shaped lug 55 adjacent its lower end as shown best in FIGS. 1, and 13. These parts form a portion of the means for supporting the outer head on the adjacent bracket post member 23, a pair of U-shaped members 56 being bolted to the plate 54 and carrying screw threaded rods 58 which extend outwardly from the bracket and through holes in an angle member 59 secured to the upper end of the post member 23, nuts 60 being provided on both sides of the angle 59 to facilitate the positioning of the upper portion of the form plate 24 with respect to the upper end of the post member 23.
A U-shaped member 61 is similarly bolted to the lower plate 55 on the head 42 and carries a screw-threaded rod 62 which extends outwardly through holes in the walls of the post member 23, and is provided with nuts 63 for positioning and supporting the lower portion of the form plate from the post member 23. Preferably, an angle member 65, seen best in FIG. 5 is welded to the lower portion of the post member 23 so that wedge blocks 66 may be inserted intermediate the ends of the angle member 65 and the adjacent ends of the members 36 of the form plates.
Generally, the opposing or inner head 43 as shown in FIG. l is supported from the outer head 42, although the inner head also rests on an immediately lower inner head 43. For this purpose bolt devices B are inserted intermediate the outer and inner heads, as shown best in FIGS. 1, 4, 6 and 14. These bolts are generally of a form cornprising a central rod 70, a pair of collars or washers 71 screw threaded thereon, screw threaded sleeve members 72 and 72 extending outwardly from the collars, and nuts 34 and 73 on the outer ends of the screw threaded members 72 and 72 respectively. As shown in FIGS. 6 and 14, a rectangular plate washer 74 is inserted between the nut 34 and the adjacent angle members 25. The outer heads 42 are provided with channel members 44 in order to provide the concrete wall W with vertical ribs 7S (FIG. 4). As it is frequently not necessary to provide the inner surface W of the wall with similar vertical ribs, the inner head 43, as shown in FIG. 4, is provided with a relatively at surface extending between the adjacent form plates 40.
To secure the inner form plates 40 to the inner head 43, the inner heads 43 are provided with inwardly extending screw threaded rods 80 as shown in FIGS. 1, 4 and 11. A form plate bracket consisting of a pair of vertically extending and parallel angle members 81 and 82 and angle cross members 83 are positioned with the angle members 81 and 82, as shown in FIGS. 4 `and 11, against the adjacent ends of the form plate members 36, and are tightened against the form plate members by means of nut devices 87 on the screw threaded rods 80, the rods 80` extending through openings or slots in the angle members 83.
In addition to supporting the form plates, the brackets also serve `as a means for supporting an upper scaffold bracket 90 and a lower scaffold bracket 91. The upper scaffold bracket 90 is suitably secured at its inner end to the post member 23 by means of a bolt 92 (FIG. 6) and at its outer end carries a vertical post 93 reinforced by a plate 94. The customary scaffolding boards 95 are supported by these brackets. Preferably, a brace 96 is provided intermediate the outer end of the bracket and the plate 27 on the channel-like members 20.
Similarly, a lower scaffolding bracket 91 has an upright post 98 and a reinforcing plate 99. The inner end of the bracket 91 is bolted to angle members 100, FIGS. 1, 8 and 9, the upper ends of which are bolted or riveted to the lower ends of plates 25 of the channel-like member 20. The lower ends of the members 100 are secured to one end of a brace 101 (FIG. 9), the other end of which is secured to the bracket 91. Planks 102 rests on the bracket 91. Preferably, the posts 93 and 98 of the scaffolding brackets are provided with pipe railings 103. The scaffolding boards 95 and 102 shown in FIGS. l, 2 and 3 on the inside of the wall W are adapted to be supported by inside brackets 10.
In using the invention, the lowermost portion of a concrete wall is generally formed by using form plates supported by other means and is provided with bolt devices B aligned vertically so that they may be entered through the slot 21 in the members 20. Outer and inner brackets are then secured to the lower portion of the wall in positions to support form plates 24 and 40 in the manner shown in FIGS. 1 to 3. After concrete has been poured between the form plates 24 and 40 around an entire Wall structure and the concrete has set sufficiently, the nuts 34 and 73 on the bolt devices B are loosened after blocks and tackle or other hoisting devices (not shown) have been secured between ring devices secured to the plates 74 on the upper bolt devices B of a previously formed section of the wall and hook bars 111 (FIGS. 1 and 8) secured to the lower ends of the members 20. Then with the nuts on the bolts loosened, the various brackets may be raised until the form plates thereon are in raised positions similar to that shown in FIG. 1.
When form plates are four feet high the crew may raise a rst pair of outer brackets about two feet and then While those brackets are raised the additional two feet, other crew members raise adjacent brackets so that the scaffolding never slants more than two feet between adjacent brackets. The form plates are held and carried up by the heads at the brackets, the intermediate heads, being elevated manually or leapfrogged one over the other for each four foot elevation of the brackets.
Preferably, as a safety feature, the brackets are provided with holes 111 in the angles 25 and plates 25 to receive bolts 112 (FIGS. 1 and 10) which extend across and above members 72 on adjacent bolts B (FIG. 14) so as to engage therewith and prevent falling of the bracket. If the bolts B are spaced two feet apart vertically in a particular installation the holes 111 for example may be one foot apart.
