ATTORNEY Filed March 17, 1951 United States Patent SCAFFOLD ANCHOR FOR STRUCTURES Eugene Peter Di Cesare, Long Island City, N. Y. Application March 17, 1951, Serial No. 216,147 2 Claims. (Cl. 248-221) CONCRETE This invention relates to scafiolding used in the construction of concrete walls and the like, directed to an anchor, which supporting individual brackets, on which the scaffolding is mounted, the anchor being the brackets and the scaffold, which is mounted on them, are supported by the metal forms.

Due to the thin sections used in the construction of different method of supporting the scaffold, in perform the surface finishing, or other operations necessary, after the concrete has set. This necessitates hanging scaflfolds from the top of the structure, by means of ropes and pulleys, or independently supporting the scaffold from the ground. Both of these methods require a separate and distinct scaffold structure for the finishing operations, and are therefore relatively costly and time-consuming.

The object of my invention is to provide an anchor, which may be imbedded in the concrete structure during the pouring process, so that the scafiold brackets, used for higher sections of the wall, may be supported in such a manner that they remain in of the uppensections and after the forms are removed bject is to provide an anchor, the exposed section of which can be readily removed, after the concrete has set, by burnin sawing, or other suitable means, the cavity formed by the burning being filled in, so that the finished concrete surface is smooth over its entire area.

Another object is to provide a simple, relatively inwhich can be located and aligned in e surrounding section of the concrete has set.

Another object is to provide an anchor for scaffold brackets in which the exposed section is relatively small and compact, so that the exposed section can be removed burning torch, or other suitable cutting means, in a minimum of time, and with a minimum of wall surface disfigurement, after the scaffolding is no longer needed.

It will be understood that the following description of the construction and operation of the Scaffold anchor for concrete structures, is intended as explanatory of the invention and not restrictive thereof.

-In the drawings, the same reference numerals designate the same parts throughout the various views.

ne embodiment of the construction, shown in Figs. 1, 2, and 3, comprises an anchor 10, made of steel or other suitable material, of rectangular cross-section, the rear portion of which is imbedded in a concrete wall 11, during the pouring thereof, and supported by the wall.

The anchor 10, as indicated in detail in Fig. 3, comprises a horizontal section 12, having at the forward projecting end thereof, with a substantially in tlhe usual manner, and determine the position of the wal The brackets 18, used to support the scaffold, may be formed with a horizontal and vertical angle section 19 retain the scaffold planking in place.

23, may be attached to the vertical A ledge 26, or a set of prongs, somewhat longer than the depth of the form sections 17, may be formed integral with the lower end of the vertical section 20 of the scafiold bracket, the location of the loop end of e projecting portion of the dental removal of the bracket.

In constructing the wall, the form sections are placed against the location of the wall surface in the usual manner, and a plurality of anchors 10, supported between adjacent form sections, as indicated in Fig. 1. The longitudinal spacing of the anchors conforms to a loop 14 formed 3 the requirements of the bracket spacing which is determined by the length of the scaffold planks.

After the portion of the concrete in which the anchor is located has set, a bracket 18 may be moved along the forms, the pin 23, attached to the bracket, being inserted through the opening, formed in the anchor loop.

The lower form sections 17, located adjacent the section of the wall which has set, may be removed without disturbing the scaffold brackets, or the anchors, and another set of anchors located in the concrete wall, a considerable distance above the anchors 10, to support the next level of the scaffold in the manner hereinbefore described.

This allows several tiers of scaffold to be supported on the concrete wall, after the forms have been removed, thus enabling the workmen to perform the necessary surface finishing and smoothing operations on the concrete wall, without disturbing the scaffold structure.

After all finishing operations on a scaffold bracket tier are completed, the projecting portion 28, of the horizontal section of the anchor may be cut off by means of an acetylene torch or other suitable cutting means, the end being cut back a short distance into the surface of the w6all, thereby forming a shallow cavity, as indicated in Fig.

A cement, or other suitable filling 29, may be applied to fill the cavities, formed during the cutting process, the surface of the filling being smoothed in alignment with the surface of the concrete wall, as indicated in Fig. 6,

thus providing a smooth wall surface throughout, after the wall finishing operations are The form of the anchor may be altered considerably depending upon the depth of the concrete wall, and the weight supported by the individual scaffold brackets.

The form and size of the loop, formed at the forward end of the anchor may be altered considerably, depending upon the type of bracket support pin used, and the method of inserting the pin in the opening formed in the loop.

The form and size of the scaffold brackets 18 may be altered considerably, depending upon the spacing of the brackets, and the Weight to be supported by individual scaffold brackets.

The location of the loop, formed at the projecting end of the anchor, relative to the wall surface, would be determined by the thickness of the concrete forms used, to provide clearance for the removal of the forms.

It will be apparent to those skilled in the art that my present invention is not limited to the specific details completed.

described above and shown in the drawings, and that various further modifications are possible in carrying out the features of the invention without departing from the spirit and scope of the appended claims.

What I claim is:

1. A scaffold bracket support for a concrete wall comprising an anchor, said anchor comprising a substantially horizontal section, a portion of said horizontal section being imbedded in the concrete wall with the balance thereof projecting beyond the wall surface, a substantially perpendicular section'integral with the imbedded end of the horizontal anchor section and a ledge integral with the perpendicular section, said anchor having a loop formed in the projecting section thereof, a scaffold bracket mounted adjacent the projecting section of said anchor, a pin attached to said bracket fitting the loop formed in the adjacent anchor to removably support the bracket, said pin having an opening formed therein adjacent the outer end thereof and means fitted to said opening retaining the bracket against the anchor, said support means resting directly against the horizontal section of the anchor.

2. A scaffold support for a concrete wall, comprising an anchor, said anchor comprising a substantially horizontal section, a portion of said horizontal section being imbedded in the concrete wall with the balance thereof projecting beyond the wall surface, a substantially perpendicular section formed integral with the imbedded end of the horizontal section of said anchor and a ledge formed integral with the perpendicular section, said imbedded anchor sections retaining the anchor within the wall, the projecting portion of the horizontal section of said anchor having a loop formed thereon, a scaffold bracket mounted adjacent the projecting portion of said anchor, a pin attached to said bracket fitting the loop formed in the adjacent anchor section to removably support the bracket, said pin resting directly on the horizontal section of the anchor, and means retaining the bracket against the adjacent anchor section.
