WALL PILASTER TIES William H. Kenney, Teaneck, N. J.

Application April 8, 1954, Serial No. 421,816

2 Claims. (Cl. 25-131) This invention relates to pilaster form structures used in the construction of concrete poured pilasters, and more particularly to ties by which the pilaster form is secured to the wall form structure.

The term pilaster as hereinafter used refers to a reenforced wall section in the nature of a column. Poured concrete pilasters project beyond the wall surface and are formed integral therewith.

To form a poured concrete pilaster, a wall form (hereinafter referred to as a pilaster form) is laterally displaced from the remainder of the wall form panel structure. Ties or other means, such as Wood studding, are employed to join the pilaster forms with the wall form structure. Present pilaster ties are constructed to meet each pilaster design. It is therefore necessary at the construction site, where pilasters of varying size are to be formed, to have available many different lengths of ties to meet each particular pilaster need. Alternately the ties may be fabricated at the site of construction for each pilaster design. The employment of either of the aforesaid methods is time consuming and greatly complicates the construction supply problem. In addition, many of the aforesaid ties are not reusable.

Accordingly, it is an object of this invention to provide a pilaster tie which can be used and reused in the construction of various size pilasters.

Another object of the present invention is to provide a prefabricated pilaster tie which can be quickly and easily anchored to the pilaster form and the wall form.

A further feature of this invention is to provide three pilaster ties, so constructed that singly or in combination with each other, they can be employed to meet almost all pilaster requirements.

A feature of this invention is the arrangement and spacing of the anchor openings in the pilaster ties to produce a wide variety of tie lengths.

Another feature of the present invention is the ability of two relatively short pilaster ties to be coupled together at various points thereby providing a wide range of tie lengths beyond the length of either of the said ties.

A still further feature of the present invention is the arrangement of the points of coupling so as to permit small variations in length.

The invention consists of the construction, combination and arrangement of parts, as herein illustrated, described and claimed.

In the accompanying drawings, forming a part hereof is illustrated two (2) forms of embodiment of the invention, in which drawings similar reference characters designate corresponding parts, and in which:

Figure 1 is a fragmentary view in perspective of a portion of a wall form and a pilaster form secured together by pilaster ties according to this invention with certain parts cut away for clarity.

Figure 2 is a plan view in elevation of a pilaster tie according to a first embodiment of this invention.

Figure 3 is a plan view in elevation of a pilaster tie according to a second embodiment of this invention.

Figure 4 is a plan view in elevation of a pilaster tie extender according to this invention.

Figure 5 is a perspective view of two pilaster ties secured together according to this invention and showing the coupling means.

Figure 6 is a series of sectional views, on a greatly reduced scale, showing a few of the many tie combinations that can be formed to produce a wide range of tie lengths.

Referring to the drawings, specifically Figure l, 10 and 10 designate a front and a rear wall form assembly, respectively. These assemblies are constructed of prefabricated panels 11. Each panel 11 comprises a frame 12 which supports on its front edges a panel face 13. The panels 11 are held together at their edges along the frame 12 by a fastening means not shown.

A pilaster form 15 is erected upon the footing 16 spaced from the plane of the wall form assembly 10 The pilaster form 15 is constructed of one or more panels 11. As shown in Figure 1, the pilaster form 15 is made up of two panels 11. The panels 11 are joined along their frame members 12 by a fastening means 19.

Interposed between the far wall form 10 and the pilaster wall are corner posts or columns 20 which are connected to the near wall form 10 by key and wedge fastening means 21. Fastening means 21 also anchors a wall tie 22 between the corner post 20 and the near wall form 10 The ties 22 are provided with weakening notches 23, at which point the ties are broken after the pouring operation and the wall forms are removed.

The pilaster form 15 is secured to the wall form structure 10 by pilaster ties 24. One end of the pilaster tie is anchored between the corner posts 20 and the near wall form 10 by key and wedge fastening means 21. The other end of the tie 20 is connected to the pilaster panels 11 between the panel frame 12 and a U-shaped channel 17. The fastening means 21 is employed to anchor the ties 24 to the panel frame 12. Wall ties 31, connected at one end to the rear wall form 10 and at the other end between the abutting frame members 12 of the pilaster panels 11, add strength and rigidity to the pilaster wall 15 at the point where the panels 11 are joined.

The pilaster ties 24 shown in Figure 1 may be either the tie shown in Figure 2 or the tie illustrated in Figure 3. These ties have been arbitrarily designated as 0" ties (Figure 2) and E ties (Figure 3). The ties 24 are so marked at 40 to provide a means of quick identification of a particular tie in the field and in the construction drawings.

As shown in Figures 2 and 3 the pilaster ties 24 are flat elongated metal bars having a plurality of openings 28. To facilitate storage and handling, these ties 24 may be made in 12 /2 inch lengths. The opening or slots 28 are of a size to permit the entry of a key 29 (best shown in Figure 5). The key 29 is provided with a slot near one end of a reduced portion of the key adapted to receive a wedge 3*). The key and wedge assembly comprise the same fastening means 21 which is employed to anchor the ends of the ties 24 to the pilaster form 15 and the wall form 10. Without departing from the spirit of this invention, the openings 28 may be of any size or shape to accommodate a fastening means such as the key and wedge assembly above described.

The pilaster ties 24 shown in Figures 2 and 3 have six slots which are spaced on predetermined unequal centers as indicated by the dimensions appearing on the drawings. The tie extender 2'7 (Figure 4) is a fiat bar of, for example, 4 /2 inches in length having therein two slots 28 spaced on 2 /2 inch centers. By varying the combinations of the three ties illustrated in Figures 2, 3, and 4, there may be secured a variety of tie lengths from 2% to 24 inches by selection of any two slots in the 0" tie or 'E tiefor anchoring the tie to the wall' form 10' and the pilaster orm.15..
