I 9 Claims. (Cl. 72-105) This invention relates to improvements in devices for anchoring or' securing building accessories to building structures and it relates more particularly to a structural strip rnemberwhich can be mounted in the walls, ceilings, floors or the like of buildings in order to receive a fasteningor supporting element by means of which such building" accessories as light fixtures, conduits, pipes, outlet boxes and the like may be supported.

This is a continuation-in-part of my U.S. application Ser. No'. 547,949, filed Nov. 21, 1955 now abandoned. Heretofor'e; when it is desired to suspend building aceessories from the walls or ceilings of a building structurefformed of masonry materials, it is necessary to drill 'or' otherwise form holes in the building structure for expansion anchors or the like to receive screws to anchor the accessories to the structure. Oftent'imes it is found: that the ceiling or wall already has a pipe or conduit concealed therein at the zone in which the an- .chors' are to be located so that the anchor-receiving holes either cannot be drilled at the place required or the workman damagesthe conduit or pipe when drilling info the wall or ceiling.

The present invention provides an effective means for overcoming the difficulties encountered with the support- --ing devices heretofore used. In accordance with the present'invention, metallic strip members are provided which can be mounted in a wall, floor, ceiling or other part or a building structure during the construction of "the same so that the strips become an integral part of the building structure. Each of the strips has an outreceivea headed fastening element that can be driven 'into'tlfe slot andgripped by the strip to retain the fastening element in the slot. Inasmuch as the slot runs the len'gth' of the fastening unit, any number of fastening devices in any desired spaced relation can be mounted in each strip. As a consequence, lighting fixtures, pipes, ic 'ond'tiitsand other building accessories can be mounted ih'lalmos't any desired position or location by fastening "devices inserted in one or more of the supporting strips at the desiredlocation.

' 'Inor'der to facilitate the use of the new anchor and supporting devices, they may be provided with portions which enable the gripping portions of the strip to separate as the fastening element-safe inserted into the slot and then to contract therebyto grip and support the fasten-f ing elements in such position that they cannot be removed readily or dislodged by vibration or any reasonable application of forceth'ereto. This arrangement assures a .strong connection between the fastening elements and the ichannel strips and a positive and firm support for the accessories;

For a better understanding o'f the present invention, rfere'nee may be had to the accompanying drawing in which. 1 V i l Figured is a perspective view of a portion of one of i channel strip-with the headed fastener inserted therem positely' directed flanges 12 and t of: the strip. The flange portions 12 and 1'3 merge into sidepanels 14 and 15 which converge inwardly and termi- 10 and its: adjacent rubber strips bedded in the concrete when the -wardly opening slot extending throughout its length to.

Figure 6 is a perspective view of a portion of a modified form; of channel strip viewed from below; and

Figure 7' is a perspective view of a portion of another form of channel strip= viewed from below the strip. .1

Figures 1 to 5 show a typical form of channel strip 'of a kind embodying the present invention and by means of which the invention can be practiced. The channel strip is formed of thin, springy, sheet metal, such as sheet steel. The channel strip 10 has a flat head portion 11 provided with reversely bent edge portions forming op- 13, at the upper edge nate i'n inwardly and reversely outwardly curved flanges 16 and 17 extending lengthwise of the strip. As illustrated in Figure 5', the flanges 16 and 17'may have inner surface portions 16a and 17a which converge upwardly slightly on opposite sides of the slot 18 between them which runs the full length of the strip 10.,

In use, one or more channel strips 10 may be supported at the bottom of the mold form for casting a concrete ceiling or the like. On opposite sides of the side flanges -14an'd 15 of the channel are mounted elongated strips '19 and 20 formed of naturalor synthetic rubber or other resilient and compressible material. The concrete C may then'be cast on the mold form so that the channel strip 19 and 20' are emlatter has set. The presence of the rubber strips 19 and 20 permits the side panels 14 and 15 of the channel strips to be spread apart slightly fora purpose to be described.

Inasmuch as 'the channel units are disposed with their slotted sides at the surface of the concrete structure C, and the open sides thereof are protected by the shape of the flanges 16 and 17', the concrete cannot flow into If the strips 10 are so by means of a removable tape applied to the flanges 16 and 17 during pouring of the concrete, the tape being removed afterthe concrete has hardened and the mold form removed;

In order to secure building accessories, such as lights, conduits, pipes and the like, to the building structure, headed fastening elements 21 of the type disclosed generally in Figures 2 to 5 of the drawing are provided.

22 having a threaded end portion 23 and an enlarged,

head 24 is not important gap 18 between flanges 16 and 17 to allow the head to pass into the hollow interior of the channel strip' 10. The rubber strips 19 and 20 allow the flanges 16 and 17 -materials of inflammable nature.

to spread apart as the head is inserted and also aid in springing them back together to grip the portion of the fastener element 21 behind the head. The neck portion 25 of the fastening element 21 directly adjacent to the.

head 24 may have its opposite sides flattened as at 25a and is somewhat narrower than the diameter of the bolt portion 22. Moreover, the flats 25a on the fastener are disposed at an angle to the enlarged head 24 so that when the flanges 16 and 17 of the strip spring back against the flats, the fastener 21 will be rotated to dispose the head 24 at an angle to the slot 18. In this position the head 24 overlies the flanges 16 and 17 and resists withdrawal from the channel unit.

A most secure type of connection is obtained with the structure shown in Figure wherein the head 26 of the threaded fastening element 27 is disposed at a right angle to the flats 28a and 29a on opposite sides 0f the fastening element and the lower surface of the head 26 is undercut at opposite sides to conform to the upwardly converging surfaces 161: and 17a of the flanges. This arrangement requires the fastening element 27 to be lifted as it is rotated in order to disengage the head .from the flanges 16 and 17, an action which is unlikely site sides of the lower free edges of the reversely bent flanges 16 and 17 and having an elongated notch 33 to "engage flats 25a, 28a, 29a of the fastening elements.

The clip 30 prevents rotation of the fastening element relative to the channel strip so that disengagement of these elements is effectively prevented.

In some instances it may be undesirable to include, as a part of the channel strips, the rubber or resilient strips 19 and 20 described above. Building codes or regulations in some localities may prohibit the use of Accordingly, the channel strip can be modified to omit the resilient strips 19 and 20 and yet provide space for movement of the gripping flanges of the strip. Such a modified type of channel strip is disclosed in Figure 6 and includes a flat base portion 40 having outwardly extending wings or flanges 41 and 42 from which extend the converging side panels 43 and 44 having inwardly and reversely curved flange portions 45 and 46 defining the entrance slot 47. An inverted channel member 48 formed of sheet metal or the like is secured to the base portion 40 by means of outwardly extending flanges49 and 50 at its lateral edges whichare secured to the flanges 41 and 42 by spot welding, seam welding, brazing or in any other desired way. The side walls 51 and 52 of the channel member are of approximately the same height as the overall height of the side panels 43 and 44 and. the outwardly extending flanges 45 and 46 so that the bottom panel 53 of the channel overlies and is substantially in contact -with the edges of the flanges 45 and 46.

A centrally located groove 54 is formed in the bottom panel 53 of the channel in substantial alignment with the slot 47 between the flanges and the groove 54 is provided with a plurality of openings 55 through which support- .ing elements 21 can be inserted.

Inasmuch as the bottom panel 53 of the channel member 48 is substantially in contact with the lowermost edges of the flanges 45 and 46, it does not deflect inwardly appreciably when supporting member 21 is inserted through the slot; I The width of the bottom panel' .53 is wider than the combined widths of the flanges 45 and 46 and the slot 47 so that the flanges can spring outwardly to admit the head of the supporting element into the slot 47. H i

The above described channel strip can be used in the same manneras the channel strips disclosed in-the Figures 1 to 5 and has the advantage of being even stronger because of the reinforcing action of the channel member 48. f

Another channel strip 60 is disclosed in Figure 7. It is substantially the same as the channel strip disclosed in Figure 6 with the exception that the groove 61 in the base 62 of the channel member 63 is not provided with openings therein. However, the channel member 63 is formed of a relatively thin metal so that a wedge-shaped supporting element 21 can easily be driven through the metal in the groove 61 and into the slot 64 in the channel strip 60. The close proximity of the channel member 63 to the side panels of the channel strip prevents substantial distortion of the channel member when the supporting elements are driven through the bottom of the groove. This form of channel strip has the added advantage of requiring no covering to prevent entry of concrete into the strip during pouring of the concrete, inasmuch as the sides and bottom of the channel strip are completely closed. The ends can also be closed by providing suitable end caps for the ends of the channel strip, if desired.

It will be understood that the channel strips, when mounted in the ceiling of a structure, may be covered With a protective strip and may be concealed by plaster or the like on the ceiling or wall. However, if it is desired to attach an accessory such as a light bracket, the plaster can be opened at a point overlying the strip and fastening elements 21 are driven into the exposed channel portion to securely anchor the element in place.

Moreover, the size of the channel strips and the fastening elements can be varied depending upon the service conditions under which they are used. For example, when they are mounted in oflice buildings or the like Where the accessories are light in weight, the channel strips may be on the order of an inch deep or smaller. On the other hand, when used in industrial establishments for supporting pulleys, machinery and the like, the channel strips may be made much larger and of much heavier material commensurate with the load to be supported.

The presence of the channel strips in a concrete ceiling or the like does not adversely afiect'the strength of the ceiling inasmuch as the channel strips in themselves will be in the nature of reinforcements for the concrete.

Therefore, the channel strips more than compensate for sidered as illustrative and not as limiting the scope of the following claims.
