2,794,234 CONCRETE FORM TIE George F. White, Monterey, Calif. Application April 16, 1954, Serial No. 423,665 1 Claim. 01. 25-131 This invention relates to' masonry and concrete construction, and more particularly to a novel tie for use'in assembling and holding forms for poured concrete construction in spaced relationship. 7
The primary object of this invention resides in the provision of ties for use in conjunction with spaced concrete forms for holding the forms in an assembled position prior to the pouring of the concrete mix.
A further object of this invention resides in the provision of ties for use with forms which may be made in elongated rolls or strips and which may be cut to the desired size necessary, dependent upon the size of the wall being cast.
A further object of the invention resides in the provision of a concrete form tie, parts of which may be used and reused.
Still further objects and features of this invention reside in the provision of ties for concrete forms that are strong and durable, simple in construction and manufacture, easy and inexpensive to utilize, while being highly eflicient in operation.
These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by these concrete form ties, preferred embodiments of which have been illustrated in the accompanying drawings, by way of example only, wherein:
Figure l is a side elevational view of the form tie assembly showing the forms in section;
Figure 2 is a horizontal section view as taken along the plane of line 2-2 in Figure 1;
Figure 3 is a vertical sectional view as taken along the plane of line 3-3 in Figure 1 illustrating the construction of the locking plates in greatest detail;
Figure 4 is a side elevational view similar to that of Figure 1, but showing a modified form of the invention;
Figure 5 is a horizontal sectional view as taken along the plane of line 5-5 in Figure 4;
Figure 6 is a vertical sectional view as taken along the plane of line 6--6 in Figure 4, illustrating a modified form of locking plate;
Figure 7 is a perspective view of a further modification of the invention; and
Figure 8 is a perspective view of one of the means utiized for engaging the inner faces of the forms.
With continuing reference to the accompanying drawings, wherein like reference numerals designate similar parts throughout the various views, and with particular reference initially to Figures 1 through 3 and 8, it will be noted that the form ties comprising the present invention and which are generally indicated by reference numeral 10 include a pair of elongated straps 12 and 14 which extend between spaced concrete forms 16 and 18. The forms 16 and 18 have apertures, as at 20 and 22, therethrough through which the straps 12 and 14 extend with the ends of the straps 12 and 14 extending above and below the horizontal whales 24 and 26 which Patented June 4, 1957 bear against the vertical whales 28 and 30 which, in turn,
bear against the forms 16 and 18.
A pair of U-shaped plates 34 and 36 over the straps 12 and 14 and between adjacent wide portions 38 of the straps 12 and 14, the wide portions being interconnected by narrow portions 40 in an integral manner. The wide portions of the straps 38 are apertured, as at 42. The U-shaped plates 34 and 36 have upper cross-portions 44 provided with pointed pins 46 which'are adapted to 16 and 18 when the the weight of concrete applied thereagainst. the plates engage the respective straps 12 and 14.
Referring now to the embodiment of the invention as is shown in Figures 4 through 6, it will be noted that in this form of the invention, the straps 70 and 72 are inserted within a hollow cylinder 74 which extends through the apertures 76 in the form 78. The straps 70 and 72 have their end portions extending above the horizontal whales 79, as well as below the horizontal whales 79, the horizontal whale 79 bearing against the vertical whale 80 which bears against the form 78. The cylinder 74 is provided with collars, as at 82, thereon, or optionally a plurality of the cylinders can be utilized one on each side of the form with the cylinders abutting against each other in the middle of the space between the forms. The collar 82 abuts against the form 78, and a pin 84 extends through apertures in the cylinder 74 as well as through the apertures 89 in the straps 70 and 72 so as to lock the straps 70 and 72 within the cylinder 74. A pliable tube 85 of rubber or other flexible material is detachably positioned about the straps 70 and 72 and extends between the spaced forms so that the straps 70 and 72 and consequently the tube 85 can be withdrawn after the cast material has set.
Positioned against the horizontal whale 79 is a bearing plate 86 which is engaged by adjustable setscrews 88 threadedly engaged within a locking plate 90, the locking plate 90 having a central aperture 92 as well as recesses 94 and 96 opening into the central aperture 92. The neck portions 98 which join the wide portions 100 of the straps 70 and 72 are receivable within the recesses 94 and 96, and these narrow portions seat in the recesses. Then, utilizing the setscrews 88, the straps 70 and 72 may be tensioned to cause the collars 82 to bear against the forms 78.
In the embodiment of the invention as is shown in Figure 7, it is noted that the straps and 112 are merely secured to the horizontal whales by means of nails or other fasteners 114 and 116.
From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may are positioned become embedded within the forms 34 and 36, as indicated at 48 and 50, lockingly 36 to abut against the forms,
be resorted to, falling within the scope of the appended claim.
What is claimed as new is as follows:
A tie for spaced concrete forms comprising a pair of elongated straps, each of said straps having integrally formedalternating narrow and wide portions, said wide portions having apertures therethrough, said straps having ends extending through apertures in said forms, means carried by said straps engaging the inner faces of said forms, and lockikng means engaging the ends of said straps holding said straps, under tension with said first recited means bearing againstsaid forms, said first recited means comprising substantially U-shaped plates each receivable in overlying relationship about said straps between two wide portions of each strap, said plates having prongs for engagement Within said forms, said locking means including a pair of locking plates having central apertures, said locking plates having tongues extending into said apertures, said tongues engaging said straps within apertures in said wide portions, vertical Whales supporting said forms, horizontal whales engaging said vertical whales, ends of said straps overlying and underlying the horizontal Whales, and wedges between said locking. plates and said horizontal whales.
