Application April 27, 1936, Serial No. 76,580
This invention relates to concrete form retaining means of the general type and kind disclosed in my prior Letters Patent of the United States No. 2,014,080, dated September 10, 1935; and this into the form.
The invention has for an object to provide form wall engaging means cooperative with tie means and spacer means, whereby the form walls are supported in desired predetermined spaced apart l or spread relation against both outward and inward collapse, novel means being also provided in connection'with said spacer means for supporting reenforcing rods or bars in predetermined position within the form and in desired spaced relation to a form wall, preparatory to casting concrete into the form and in imbedding relation to said reenforcing rods or bars.
I Other objects of, this invention, not at this time more particularly enumerated,wil1 be understood from the following description of the same. V
Illustrative embodiments of this invention are shown in the accompanying drawings, in which: Fig. 1Iis a fragmentary vertical cross section through a form showing the wall retaining rela- 36- tions of the supporting, tying and spacing means therefor and the means for holding inserted reenforcing rods or bars; Fig. 2 is a horizontal section through the same, taken on line 2-2 in said Fig. 1;. Fig. 3 is a similar horizontal section, 35 showing the use of auxiliary form wall spacing means.
Fig. 4 is a perspective view of a spacer device havingmeans-to embrace and position one or more reenforcing rods or bars within the form 40 interior. I
Fig. 5 is a horizontal section, similar to that of Fig. 2, but showing a modified arrangement of the form wall tying and spacing elements of the wall retaining means; and Fig. 6 is a fragi5 mentary vertical section, taken on line 6-5 in Fig. 5, but drawn on an enlarged scale. 7
Similar characters of referenceare employed in the above-described views,to indicate corre- V spending parts. 50 Referring to the drawings, the reference char acter l0 indicates the opposed walls of a concrete form to the exterior faces of which are applied,
in suitably spaced apart relation, the uprights V or battens ll, across the exteriors of which extend the spaced walers l2.

of a form wall l0.
9 Claims. (01. 25-131) The form wall retaining means, in one arrangement, as utilized to extend through the form walls and form interior, comprises a unitary tie- Cooperative with each form wall is a wall penetrating sleeve. In preferred construe 5" tion, each sleeve comprises a longitudinal split to provide separable members, which, for convenience of description, will be designated a lower sleeve member l4 and an upper sleeve member l5. These sleeves are engaged over and 10' around said tie-rod l3, whereby the latter extends axially therethrough. The inner end portion of the lower sleeve member I4 is formed to provide a tapered section it which starts flush from the exterior surface thereof. The inner end '5 portion of theupper sleeve member I5 is also formed to provide 'a tapered inner end section H, which, at its juncture with the exterior surface thereof, is eccentric thereto so as to provide a stop-shoulder l8 engageable with the inner face When the sleeve members i l- 45 are assembled together, their tapered sections IE-ll provide the sleeve with a conical interior end portion.- At their outer en'ds, said sleeve members l 4l5 are usually provided with laterally projecting perforate or indented ears'or lugs l9, through one or both of which may be passed a fastening nail 20 adapted to be driven into the form wall with which the sleeve is associated, to thereby hold the sleeve members, and especially the lower sleeve member l4 against accidental outward displacement from its operatively arranged relation to the form wall served by the sleeve. V p
The form walls II] are provided with through openings 2| of a diameter sufficient to receive and fit the circumference of the outer portions of the sleeves as formed by the assembled sleeve members l4-l5.
Cooperative with the sleeve and tie-rod is a spacer element 22 having a longitudinal bore 23 through which the tie-rod l3 extends. In assembling the form retainingmeans, the tie-rod i3 is passed through the form'walls and form interior from oneexterior side of the form to the 5" other exterior side thereof,'and the spacer element 22 is slid onto the tie-rod It so as to ride upon the portion thereof which lies intermediate the form walls l0. Since the diameter of the V tie-rod I3 is considerably less than thediameters 5 of the form wall openings 2|, the tie-rod will rest temporarily upon the bottom sides of said openings 2|, thus leaving sufiicient space for the insertion thereover, from, the exterior sides of the form walls, and through said openings 2| 5 5 of the upper sleeve member l5 and their stop shoulders I8, whereby the latter may be positioned to engage or abut the interior faces of form walls In. After the insertion of said upper sleeve members !5, the lower sleeve members It may be engaged beneath the tie-rod l3 and then inserted through the form wall openings 2| until registered with the upper sleeve members I5, whereby the latter are moved laterally in the openings 2| to position the stop shoulders 13 thereof for engagement with the inner faces of the form walls It].
In order to assure the spacing apart of the form walls H at a predetermined distance, according to the thickness of concrete wall desired to be produced, the length of the form penetrating tapered end portions lt-ll of the sleeve members I4-l5 are suitably predetermined, as is also the length of the spacer element 22. For example, said tapered end portions Iii-4? of the sleeve members l4-l5 may be furnished with a length of three inches, and the spacer element 22 of a length of two inches, whereby when these parts are arranged end to end as assembled between the form walls, said walls will be spread in a spaced relation of eight inches so that a cast wall of the latter dimension in thickness will be reproduced. It will be understood, that these part dimensions are subject to a wide range of variation in dimension, the above recited dimensions being mentioned only by way of example. It will also be understood, that where thicker walls are desired to be made, auxiliary spacing sleeves 24 of suitable length may be employed on the tie-rod l3 and between a sleeve device 14-45 and the primary spacer element 22, as shown in Fig. 3.
After the tie-rod, sleeves and spacer element or elements have been assembled and put in place, flanged keeper nuts 25, or any other suitable form of locking-up means, may be applied to the exteriorly projecting ends of the tie-rod I3. If keeper nuts 25 are employed, the end portions of said tie-rod it are threaded to receive the same, so that the nuts may be screwed home on the tie-rod ends to engage their flanged side in abutting relation to the walers l2, and thus press home the form walls it! against the stop shoulders !8 of the sleeves Hll 5, so that the said walls are firmly secured in desired mutually spaced apart and fixed relation against both inward and outward displacement.
It being frequently desirable to insert within the form interior upstanding steel rods or bars to be imbedded in the concrete mass of the wall as reenforcing therefor, I have devised in combination with the spacer element 22 novel means for supporting such rods or bars in upstanding relation and extension within the form interior, and in positions calculated to dispose the same in desired spaced relation to an exterior face of a wall formed by casting concrete into the form. To this end integrally formed in connection with the spacer element I provide a laterally projecting horizontal flange 25 provided with one or more openings 27 therethrough, three such openings being shown in the drawings by way of illustration. Preferably, although not necessarily, the walls of these openings may be interrupted by gaps or breaks 28, leaving bendable fingers 29 bounding a portion of the peripheries thereof. When such bendable fingers are employed, the size of the openings 21 may be contracted by inward bending of the fingers, so as to reduce the same to fit a rod or bar 38 passed therethrough, whereby the latter is firmly gripped or clamped by the in-bent finger, and thus securely held in straight up-standing position within the form interior. Ordinarily it is required that reenforcing rods or bars, when employed, be spaced given distances inwardly from an adjacent surface of the wall in which the same are imbedded to serve as reenforcement for the wall. To accommodate my novel rod or bar supporting and holding means to this practice, I extend one end, as 3| of the flange 26 beyond an end of the spacer element 22, so that an outermost opening 21 is provided so located, for example, as to support a bar or rod applied therethrough at a minimum distance of two inches from the form wall, and consequently ultimately at that distance from an exterior face of the Wall cast in the form. The remaining openings 21, are spaced ordinarily on one inch centers, so that a selective disposition of the rod or bar more distant from the adjacent form wall may be obtained if desired. It will be understood that the suggested spacing dimensions are, of course, subject to wide variation.
In the use of the novel concrete form and reenforcement retaining means above described, it will be understood that the sleeve members l4--Hi may be manipulated, the form walls dismantled, and the tie-rods l3 withdrawn substantially in the manner and with all the advantages fully set forth in my prior United States Letters Patent No. 2,014,080 above referred to. When a unitary or continuous tie rod, as 53, is employed, and the same is withdrawn from the finished cast concrete, while the spacer element 22 and the supported reenforcing rods or bars 38 are left imbedded in the concrete mass, a transverse opening or hole remains extending through the latter when the tie-rod is withdrawn. This, in some cases, may be found objectionable, if so, I may employ a modified tie-rod and spacer element arrangement as" shown, more. particularly, in Figs. 5 and 6 of the accompanying drawings. In this modified arrangement, the bore of the spacer element 22 is internally screw-threaded, and in place of the single unitary tie-rod I3, I employ two rods or bolts 32 and 33, each having threaded inner end portions. These rods or bolts 32 and 33 are respectively passed through the respective form walls In and associated sleeves, and their inner threaded ends are screwed into the ends of the threaded bore of said spacer element 22, thus uniting the same therewith. The outer ends of the rods or bolts 32 and 33 are provided with the flanged keeper nuts 25 or equivalent or any other suitable means for locking up and retaining the form walls [0 in place as governed by the tying and spacing arrangements. In this case, the spacer element 22 is provided, in its side walls, with upper and lower openings or slots 3 so that when the concrete is poured into the form, the same will flow into the bore of said spacer element, and between the ends of the rods or bolts 32--33, thus plugging or closing up the bore and interrupting any opening extending through the cast concrete mass after the rods or bolts 32-33 are withdrawn. It will be understood that, additional auxiliary spacing sleeves, as 24, may-also be used with the above described modified construction, if itis so desire-d. 7
While I have shown the spacer element provided with but one perforate flange 26, it will nevertheless be understood that more than one such may be provided and that the spacer sleevemay be disposed to position the same in either horizontal, vertical or angular planes, according to the position in which it may be desired to dispose the. reenforcing rods 30 within the form interior. Q
It is also to be noted that the spacer element or sleeve 22 with its reenforcing rod or bar holding means, as above described,1may be applied to an ordinary tie-rod unequipped with the form the scope thereofas defined in the herefollowing claims; hence, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
