ANCHOB INSERT.

Application filed November 15, 1324. Serial No. 750,159.

My invention relates to Concrete Construction and more particularly to an anchor insert and the method of installing the same for the attaclnnent of sleepers, fei-ring, interior finish, light machinery and analog'ous purposes.

The object of the present invention is to simplify the str `ctnre as Well. as the means and mode of setting or applying such anchor inserts or grips- Which may be embedded in the Concrete structure, either by being attached to the interior of the form or .meld and around Which the Concrete is poured While in a fluid or plastic stage, or Which may be einbedded in lfloors, or in the top of other substantially horisontal Concrete bodies by being thrust into the body of Concrete While the latter is yet in a semi-liquid or p astic state. For either method of embedment, the anchor insert consists of an initially snbstantially right engle member formed of flexible material, preferably, tho not necessarily, stamped from sheet metal, one armof Which is preferably embossed, corrugated or of otherwise r irregular outline to atferd interlocking anchorage With the Concrete body while the portion initially projecting at right angles thereto is perforated to receive nails to Secure it to the interior of the inold form and later to the sleeper, the furring strip or other at tached members. Such right angle anchor im sertel may be intel-connected in pairs to insure their embedment in proper spaced relation. Subsequently to the setting or hardening of the Concrete body in Which the anchor inserts are embedded, the laterally extendin;` portions of the inserts initially extending perpendicular to the embedded corrugated arm and parallel With the surface of the Con- Crete body are then bent upwardly perpendicular to such Concrete body and into substantial alignment With the embedded portion of the anchor. Such upstanding portions of the anchor insert are subscquently attached to the sleepers1 furring strips or other members to be secured.

The method of installing such anchor inserts hereinafter described enables the accurate placement of such insert in proper alignment With each other and separated predete 1inined distances equivalent to the Width of the sleeper or furring strip to be received therehetween. I

I i of the obi q of the mfeatlen is to are. :w well the means and mode of installation of such anchor inserts, Whereby they Will not only be cheapened in construction, but Will be more efiicient in use, capable of being` securely and flrmly embedded, durable, easily applied and unlikely to get out of order.

A further object of the invention is to provide a simple, and inexpensive form of an- Chor insert, which may be secured in a retracted form to the interior of a Concrete meld or form, or embedded directly in a body of Concrete while in a plastic condition and subsequently extended by outbending` after the body of Concrete has become set and hardened.

A further object of the invention is to provide means and method by Which such anchor inserts may be quickly and accuratcly installed by unskilled laber.

lVith the above primary and other incidental objects in vie'n7 as Will more fully appear in the specification, the invention consists of the features of construction, the parts and eombinations thereof, and the mode of operation or their equivalents as hereinafter described and set forth in the claims. In the aecompanying drawings, Wherein is shown the preferred, but obviously not necessarly the only form of embodiment of the invention, Fig. 1 is a perspective view of a Concrete surface on Which has been laid a locating gage herenafter described and illustrating a succession of anchor inserts of different form installed in the Concrete hody in conformity With the gage member. Fig. 2 is a similar view of a portion of a Concrete body subsequent to the setting or hardening of the Concrete, showing several forms of the anchor inserts forming the subject matter hereof in different stages of utilization. Fig. 3 illustrates different forms of the anchor inserts secured to the interior of a Concrete form or mold, preparatory to the pouring of the Concrete about such inserts as Would be the case on Vertical Wall surfaces and. Ccilingfs. Fie; -l is al perspective view illnstrating` tvio of the anchor inserts of right engle form interconnected into a pair to insure proper relative spacing during installation. Fig. 5 is a. detail sectional vienT illustrating application of the insert anchor to a sleeper or furring strip.

Like parts4 are indicated by simil acters of i* r throughout.. View'f r char- In laying wood fioor upon a Concrete subbase or foundation, it is desirable to anchor or otherwise secure stringers or sleepers to Which the flooring is to be nailed, to such Concrete sub-base.

Likewise in the course of Concrete building constructions, it is necessary to apply furring strips to side walls and to ceilings for Supporting interior finish, attaching interior frame partitions, for Supporting shelving and for attaching light machinery and the like, which it may be desirable to suspend from the Ceiling or secure to a side wall. The present form of anchor is adapted to be embedded in the Concrete body while still in a plastic stage, either by being initially secured to the interior of the Concrete mold or form, or by being thrust into the body of Concrete while the latter is yet in a semi-fluid or plastic stage. The anchor insert is initially installed by either method with its attachment wings or ears in a retracted or recumbent position, substantially parallel With the surface of the Concrete body, such attaehment wings being` subsequently extended to a position perpendicular to the surface of the Concrete body, for attachment to the sleeper or furring strips. Theanchor member is quite simple in its construction as is illustrated in detail in Fig. 4, where it 'is shown as consisting of a single piece of sheet metal bent into right angle U-shaped form, with the arms 9 thereof corrugated to aford secure anchorage engagement while the intermediate portion is split to form laterally extending arms 10 perforated at 12 to receive nails for initially securing it to the interior of the form or mold and subsequently to the sleeper or furring strip after the arms are bent to upright positions. In installing this anchor insert in a floor or in the top surface of a Concrete body, the corrugated arms 9 are thrust rinto the plastic Concrete until the laterally extending perforated wings 10 rest upon the surface of the Concrete body. To insure the proper placement of these inserts in alignment with each other, and in transversely separated relation, agreeing with the sides of the sleeper or furring strip to be received thereby, it is preferable to insert such anchors closely contiguous to the margin of a straight edge. For Convenience in making such installations, two straight edges 4 are interconnected one to the other by Cross ties 5 in properly spaced relation and a board 6 is interposed between the straight edges 41 and secured to the cross ties 5 upon which the workman may walk to and fro while installing the an chors by thrusting them into the plastic Concrete. The straight edges 4 are preferably tho not necessarily, marked at intervals as at 7 to indicate the longitudinal spacing of the series of anchors.

VVhile the gage device illustrated in Fig. l is particularly adapted for the i-nstallation of the duplex or paired anchors shown. in

Fig. 4, it may be also successfully employed in installing other forms of anchor inserts as illustrated in Fig. 1. In the construction illustrated in Fig. 4 the pair of right angle anchor members are formed from a single strip of sheet material, the opposite ends of the strip are bent at right anglcs to the intermediate portion and corrugated as at 0. The intermediate transverse Connecting portion between the corrugated right engle extensions 9 is diagonally cut to form two tongues or arms 10-10 separated one from the other by an intermediate diagonally disposed strand 11. The tongues or arms 10 are perforated at 12 to receive the sccuring nails. Each arm 10 and its interconnected corru- `gated extension 9 forms a right angle anchor insert. However, these right angle inserts are integrally united in prcdetermined spaccd relation by the intermediate diagonal tie 11. This tie insures the proper relative spacing of the anchor members when embedded in the Concrete body. The ga-ge member illustrated in Fig. 1 may be employed in locating these duplex or paired anchors in the plastic body as is shown in Fig. 1 at 13.

The anchor members being embedded in the Concrete body, after the latter has been allowed to set and harden, the inturned arms 10 Fig. 4, are flexed or bent upwardly to positions perpendicular to the surface of the Concrete body as shown at 111- in F 2. The sleeper 15 is then interposed between the upstanding perforated arms of the anchor insert and is secured in such position by nails 16, driven thru the perforation of such arms.

In the event that the insert anchors are to be installed in a Vertical surface, such as a wall, or in an overhanging surface as in a Ceiling, in which case it is not practical. nor possible to embed the anchors by thrusting them into the body of Concrete while yet in a plastic condition, the anchors in such case are initially installed in the interior of the Concrete form or mold. To this end the anchor members are secured to the inner face of the form by nails driven thru the perforations of the laterally extending wings 10, with the corrugated anchor arms projectinp,l perpendicular to the wall of the form or mold as is shown in Fig. 3. The form or mold being filled With Concrete which flows about the Corrugated anchor arms, the latter thorebv become embedded in the Concrete, the form is removed subsequent to the hardening of the Concrete body, leaving the perforated wings 10 exposed upon the surface of the Concrete body. These wings when bent to perpendicular relation with the surface of the wall or the ceiling as before described receive the sleeper, furring strip or other body to be secured, which is attached thereto by nails driven thru the perforation of the. attachment wings.

In Fig. 5 the relation of the anchor insert to the sleeper vand Concrete body bas been shown in sectional elevation. The initial positions of the latcrally extending perforated wings, have been shown by dot and dash lines, and their direction of hending or iexing up- Wardly to receive the sleeper or furring strip has been indicated by arrows. In the same figure different spaeing of the anchors has been illustrated by dotted lines to accommodate sleepers of different Widths, by merely varying the relative spacing of the anchor members. The present form of anchor necessitates a minimum ainount of material, all of which is used to maximum advantage. It has the further advantage of being capable of being nested Compactly for shipment and because of the minimum material required it is light in Weight, yet equally as strong in its coupling or tying function, as other sleeper grips employing a large excess of material.

lhile the perforated arms 10 have been heretofore described and hereafter referred to in the claims as perforated for initial attachment to the nterior of a Concrete form and subsequent attachment to a sleeper or furring strip, it is to be understood that the device is not limited to such attachment interiorly of the Concrete form but may be thrust directly into a plastic Concrete body. Such ability for initial attachment to a form and the herein described method of installation by pouring the Concrete about the attached insert is especially7 desirable When such inserts are to be embedded in side Walls or Ceilings. I-Iowever When applied to floors or to top surfaces of other Concrete bodies, such step of initial attachment is entirely omitted and it is not intended that the claims shall be limited thereto.

From the above description it Will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but Which obviously is sus- Ceptible of modification in its form, proportions, detail Construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

TWhile in order to comply With the statute the invention has been described in language more or less specific as to Structural features, it is to be understood that the invention is not limited to the specific details shown, but that the means and construction herein disclosed Comprises the preferred form of several modes of putting the invention into effect and the invention is, therefore, Claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.
