6 Claims. 1
This invention relates to a support connector attachment for attachment to a metal frame member.
In building construction and the like metal framework is usually incorporated whether said structure includes concrete, tile or other materials for ceilings, walls and floors. In the progress of construction certain lines, pipes, conduits etc. have to be carried along to supply at the point or elevation of work power etc. and water.
Temporary supports are usually cord or rope es which chafe and fray as well as slip. For permanent support of so-called permanent lines which obviously in a concrete, steel reinforced building must be set before the concrete is applied the prior practice has included drilling and tapping some part of the framework and then threading into such hole a bolt that carries a line support. Usually two bolts per anchorage are required. Obviously this weakens the framework. It also is expensive because of the application time required. If such a support is for temporarly use only, the framework obviously is correspondingly weakened when the support is removed and also the cost of removal is expensive.
The chief object of the present invention is to provide a support connector for metal framework application which can be readily and inexpensively applied thereto and expeditiously applied thereto for permanent and temporary use without any weakening of the frame work, and if for temporary use can be quickly and inexpensively detached from the framework leaving the latter in its initial condition.
The chief feature of the present invention resides in providing a framework flange embracing anchor plate in channel or U-shape section form which in turn centrally supports an offset or projecting support portion of cantilever type.
Other objects and features of the invention will be set forth hereinafter,
The full nature of the invention will be understood from the accompanying drawings and the following description and claims:
In the drawings Fig. 1 is a central sectional view of a metal truss structure, adjacent conduit and the support connector applied thereto, the truss being one suitable for roofs, bridges or the like.
Fig. 2 is a perspective view of the support conhector.
Fig. 3 is a view similar to Fig. 1 and of a modified form of the support connector, a conduit, and frame member, the frame member being of flange type, such as an I or H beam or even an angle.
Fig. 4 is a side view of the support connector and a portion of the conduit shown in Fig. 3.
In Figs. 1 and 2 of the drawing Ill indicates generally a portion of a truss structure having a lateral flange II with one face 12, an opposite face l3 and the side edge It. Such base portion may even constitute an angle or an H or I beam providing a projecting flange such as illustrated in Fig. 3 to which reference will be had hereinafter.
In Figs. 1 and 2 the anchorage or base portion of the connector comprises a plate bent to U-shape section formation having the upper portion l5, the root portion l6 and the lower portion ii. The terms upper and lower obviously are relative terms and are not to be taken literally.
As illustrated portion ll is of major length and portion I5 is of minor length. The plate preferably is of foraminated type having a comparatively large number of openings l8 therethrough. Interposed between the flange and U-sectioned plate is adhesive material l9 which, when applied to the flange where the connector is to be secured, and the plate is applied thereto squeezes outwardly as at 20 to form locking lugs in the plate as well as wicks to facilitate cement solvent evaporation thereby materially expediting the setting up of the cement for rigid retention of the plate upon the flange.
The cement preferably used may be that now commercially sold under the name Miracle.
This Miracle cement, or an equivalent one, is of the following character:
Synthetic resins and solvents compounded as required to produce the aforesaid or an equivalent adhesive. Such an adhesive preferably contains no asphalt and a sulphur content of less than three-fourths of one per cent. Such an adhesive develops shear and tensile strength so that the same is equally applicable for securing hangers to sidewalls and ceilings.
Thisadhesive when dry bonds tenaciously to almost all types of surfaces, especially those initially mentioned herein and is strong, tough and flexible in character.
Such an adhesive affords a permanent bond as Well as a strong initial bond, for example, six pounds per square inch adhesion within an hour and seventy-five pounds per square inch adhesion after the adhesive has set thoroughly. Consequently, each hanger of four square inches is secured to the surface with an adhesive force of twenty-four pounds at the end of one hour and three hundred pounds when fully set.
Such an adhesive, furthermore, is flexible and never becomes brittle so far as now known. It is of waterproof character both in salt and fresh water, so that should spray, etc., contact the support or moisture condense thereon, the adhesive on such support remains comparatively unaffected. So far as now known, such adhesive also remains unaffected comparatively speaking, by temperature changes, same having been tested from as low as sixty degrees below zero to two hundred fifty degrees above the same, both being Fahrenheit.
Rigid with the plate, which initially may be square in outline,- and centrally thereof, there is secured by welding or the like portion or stem 2 Stem 2| projects outwardly and oppositely from portion I! and terminates in an arcuate supp rt:-
portion 23, the connection 22 therebetween thus being of cantilever type. Herein thearcuity is greater than 180, in fact is greater than 369? but.
it may be less or greater as desired or required.
The free end, see Fig. 2, maybe-longitudinally-- In this former the or required; and the conduit-can be clamped therein by screws or otherdevices or by the free tongues as'illustrated'or merely may be partially encompassed by that end withoutclamping;
Reference will now be had toFigsp and 4.
In'Fig. 3 36 indicates a flange of an I or H beam I.
having upper face 3 i, lower face and side edge 33'. .The U-shape'd foraminated plate includes upper portion'i l, root'portionififiand lower portion'fittj It is provided'withiioles 3?. Th'e'cee ment' betweenthefl'ange and" plate is indicated bynunieral 38 and the. locking'lugs by numeral 3911 Suitably secured as by welding or the'like. and centrally of the plate is collar til. It is centrally tapped at w to'tahe screw or bolt ii by-which 1 arm 42 is anchored to the plate and'collar. This arm' may be of any desired length andprovided with a longitudinally directed notchv or slot to pass the bolt il by which the cantilever type arm is connected to and supported by the collar and plate.
When the bolt ii is loosened, the arm 42 can be slid relative to the bolt which will" position the arcuate sectioned end'tt closer to the flangeiedge or'm'ore distant therefrom whereby the'conduit Mresting onend t3 may be 'positicnedias'desired or required. When such adjustment is not required. the slot is merely a hole 35 to pass the bolt M as shown.
The arm 32 may not be as short as illustrated but may be longer and have an inclined portion to positionthe free end-53 and conduit 44 at"an elevation greater than that illustrated.
Preferably the plate at its central portion is free'of perforations and the threaded hole ie -is coextensive with the collar. Thus if in this formof the invention the plate and collar only 'ini-' tially be applied to the flange subsequent application'of the cantilever arm and anchoring screw will not rupture the cement connectio'nbetween the plate and flange.
As in the first form the free end lt'may be longitudinally slotted at 46, and a conduit clampingscrew orthe like associated therewith, if desired. This is illustrated in Fig. 1. It is preferred on Fig; 3 to illustrate the conduit sup port only form :of i the basic invention.
The. form of the invention illustratedin Figs.
3 and 4 is applied and utilized as previously described relative to the form illustrated in Figs. 1 and 2 insofar as they are commonly disclosed.
Whilethe invention has-been illustrated and describedzin great detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character;
The several modifications described herein, as well. as'others which will readily suggest themselves to persons skilled in this art, all are considered-to be withinfthe broad scope of the invention, reference being had to the appended claims.
