STRUCTURAL STEEL WRAPPING SPACER Application .ined Mariahilf, 1930. serial No. 435,814.
This invention'relates to improvements in structural steel wrapping spacers.V
It is one of the objects of the present invention to provide a spacer for structural 5, steel wrapping which is of a standard size and may be used with.V all widths of flanges.
and with all thicknesses of flanges of structural steel ordinarily encountered, therebyl eliminating the necessity of having on hand 1o and sorting various sized spacers for use on steel Vmembers of different` sizes during construction work. Y j A A further object of the invention is to provide structural steel wrapping spacers which may be applied on steel members in any desired spacing arrangement, depending upon the specifications. Y f.
Wrapping devices now on the market are constructed so that the `wrapping wire directlyV engages the lower flange of a structural'steelbeam, and in-the event of any bending the lower iiange of the beam-is where the greatest stress ordinarily occurs, and if the wrapping wire adjacent the lower flange of the beam is not completely encased inthe concrete, it will not withstand the maximum amount of stresses.
A further object-ofthe invention is to provide a structural steel vwrapping spacer which will overcome the above disadvantages by spacing or holding wire away from the lower flangev of the beam out into thel middle of the cementitious mass, whereby the wrapping wire is thoroughly encased in concrete and will develop its fullest strength. 1
. A further object of the invention is to provide a structural steel wrapping spacer and l wrapping wherein the latter, by being secured over the top flange of the beam, or on oppogages directly or indirectlyfoun edge portions of the steel member' and will therefore bind and be prevented from sliding out of position, and the spacer per se, when encased in the cementitious mass, will assist in holding the latter in place around the structural steel member.
A further object of the invention is to provide a structural steel wrapping spacer and site sides of the spacer, gives added strength' to the beam, inasmuch as the wrapping enwrapping therefor, which, when applied to Y l sIEsEL (1o.,'orv MILWAUKEE, Wisconsin, A ooRroRATIoN lor WisooNsrN f beams in concrete construction work, will notV prevent the freeowl of cementitious material around the beams.' l A further obj ct of the invention is to provide a structural steel'wrapping spacer which may be erected very easily and quickly, which is strong and durable, which 1s inexpensivel to manufacture, and which is well adapted for the purposes described.l j i With the above and other objects in View, the invention consists of the impro-ved struc-A tural steel wrapping spacer and its parts vand combinations as set forth in the claims, and all equivalents thereof. f
In the accompanying drawings `in which I the same reference characters indicatethe same partsl in all of the views:
Fig-1 is a Vcross-sectional view through a horizontally disposed structural steel beam having the improved spacers'applied thereto and wrapping engaging the spacers and the beam, .with the beam and spacers and wrapping shown encased-ina cementitious mass molded thereabout; 1

Vformed of a length of wire of a suitable gauge, or. other similar material, which'is lyelda'ble or bendable, andl said wire Vis bent to form two laterally opposed clip portions 9,4 andbelow the clip portions, are doubled over rearwardly turned portions l0 which extendV outwardly and are joined by a transverse portion ll-formed withan intermediate inwardlycurvedor recessed portion 12.' Y Y Y 8o i Fig. Llis a detail perspective viewona f f 9 of the spacer, as at 20.v When a y by the spacers. as
A structural steel I-beam 13, disposed horizontally, as in ceiling constructions, is shown in Figs. 1 and 2 and the improved spacers 8 are adapted to be applied `to the opposite lower flanges 14 thereof inthe man-- ner shown in Fig. 1 and said spacers, on each lower flange, Vmay be spaced apart longitudinally of the beam at any convenient distance. f The clip portions 9 of each spacer are yielding and engage a flange portion 14 of the I-beam and are held on said flange by the tension of the clip portions. The spacer members may be further secured to somt or form boards 15 by staples 16 engaging lower portions of the spacers and'extending into the form* boards. l/Jith pairs vof spacers disposed as shown in Fig. 1 on opposed sides of the lower flanges of the I-beam, a wrapping wire may be supported thereby and spaced from the lower flange of the I-beam. Said wrapping wire 17 is extended below the lower flanges of the I-beam and engages in the recesses 12 of the transverse portions 11 of the twoy opposed spacer The wrapping wire is then bent upwardly on bot-h sides and is extended over and around the upper flange 1'8' ofthe I-beam, and the opposite end portions of the wrapping wire are then wrapped or bent around opposite portions of the upper flange and against lower surfaces thereof, as clearly shown in Figsfl and 2. As shown Vin Fig. 4, a number of spacers 8 may be suitably joined together at spaced intervals in a longitudinal line by a longitudinally extending wire or strip 19 which is welded to lower corner portions of -the clip portions number of spacers are so ]oined they may be quick- .ly appliedto one side ofthe lower portion of 'an I-beam and will be correctly spaced and will be held in correctspaced relation.
After the application of the spacers to the lower flanges of a horizontal I-beam, and after the wrapping wire has been engaged described and bent about the upper flange of the I-beam, cementitious material, as indicated by the numeral 21, may be poured into the sofit or form boards, surrounding the beam and spacers and wrapping wire, as'shown clearly in Fig. 1. When the concrete has set, the spacing wire will be embedded in the c'ementitiousmass and will be firmly supported spacedly from the lower I-beam, givingto lthe -beam Fig. 5 illustrates the manner in which the improvedspacers are applied to a vertical l, column.
I-beamsuch as is used in forming a vertical Y In this form, the spacers are clipped ontothe flanges 22 of the vertical I-beam 13 and are positioned in vertically spaced apart arrangement on all of the flanges. The wrapping wire 17 is then bent about the beam and spacers in afsubstantiallyjsquared form and is engaged at each corner portion within a recess 12 of a spacer. The wrapping wire` so disposed is prevented from slipping and is held by the spacers outwardly of and away from all portions ofthe flanges of the I-beam. tious material 21 is poured into the form 15 it will surround or encase the I-beam, the
. spacers and the wrapping wires, and all portions of the wrapping wires will be encased in a substantial mass of concrete and will be spaced away from the flanges of the beam.
From the foregoing description it will be seen that the improved spacers, when mounted on flanges of structural steel beams or columns, securely support wrapping wire for the beams or columns and hold the wrapping wires in the proper spaced relation outwardly of the surface of the beams or columns, whereby the wrapping wires become embeddedV in the cementitious mass poured around the beam or column and the greatest possible strength is secured. The improved spacers and wrapping applied thereto do not in any way restrict the free flow of cementitious material around the steel members during the construction work, and the spacers and wrapping are of such nature' that they may be easily and quickly applied to the structural steel beams or columns. Furthermore, the improved spacers and wrapping J therefor are of simple and novel construction and are well adapted for the purposes set forth.
What I claim as my invention is:
1. In a building construction, a'flanged beam, a pair of metallic spacing members engaging opposite sides of a flange thereof, each spacing member having a yieldable clip portion and an offset recessed portion, a separate wrapping element surroundingthe beam and engaging the offset recessed portions of the spacing members and supported by said members spacedly, outwardly of all portions of said flange, and cementitious material surrounding the Vbeam encasing the same, the spacing members and the wrapping element.
2. A. structural steel vwrapping spacer, comprising duplicate, spaced-apart parallel members, each consisting of a yielding, U- shaped engaging clip with the lower arm of the clip bent rearwardly upon itself, and a transverse member joining th-e outer ends of the rearwardly bent arm portions of the duplicate clips, said transverse member having an intermediate recess to receive therein a portion of a separate wrapping element.
K In testimony whereof I afliX my signature.
