Application oc'toter'ifi, 19u32, Yserial No. 637,723- f 5 claims. a (c1. 2541315) This inventionrelates to steel panel forms used as a temporary support'for concrete flooring in the construction of buildings and *bridgesl and f more particularly to that type of form usedto support plastic concrete between .steel beams until such time as to allowY the concrete ;to become hardened and thereby self-supporting.' Y
The primary object of the invention is the con*- struction of a steel panel form'having vertical ad# justment in order to retain a plurality offorms in' the same transverse and' longitudinal plane when the surfaces of the members lsupporting the forms are not in the same plane.`
a Another object of the invention is the novel construction of a panel form and its component parts in order that it may be readily adjusted and strippedfro-m the concrete after said concrete has set and become self-supporting. Y l 'I 'Y Other objectswill become apparentto those skilled in the art, from the accompanying draw@ ings which form Va part of thepresentdescription; in which a y Fig. 1 shows in plan the supporting beams for the flooring of a bridge with the improved panel forms shown in position, vone of thefsupporting beams having a number o fffstrengthening cover plates mounted thereon. f* Fig. 2 is a sectional View 0f Fig. 1. n A Y Fig. 3 is a side elevation ofthe latch which per-- mits vertical adjustment ofthe panel form.
Fig. 4 is an end elevation ofthe latch shownin Fig.3. j y a' "L Fig. 5 is a sectional viewtaken alongline 5'v-'5 of Fig. 1 showing the arrangement of holesl in the panelv form reinforcements. Fig. 6 showsthe adjustable latch in"various positions to accommodate the differencesheight of the supporting beamsdue to the presence or absence of cover plates. a Y
Fig. 7 is a View taken along line `'I'I of Figo and shows the latch secured inposition.-
Referring now in detail tothe drawings where taken along line 2-2 l like reference characters refer to like parts, referand( 4- indicate spaced'lorngifv 2I at the end adjacent the' beamsso as to close the openings between the -T longitudinal supporting beam members ySand `Il.- As--theforms abut each other along twosidesfno flanges are usuallyY employedbut transverse angular reinforcing members 5 and 5a are secured by spotwelding, or any other desirable-method, to the underside of the topplate -I. Y -The'one'end of the` reinforcing member 5a, employing y abvertical adjusting lat'ch, preferablyterminatesfwithinthlirnits Of the depending flange 2 and the opposite end,Y extends f through the depending flange side ofthe top plate 'I.
Y Adj ac entV the extrem1ties of the reinforcements 52LV employing theA vertically Vadjustable latch are clip angles 5 secured to Vthe top plate-I inthe same lmanner thatthe reinforcing angles l5 and 5# a are secured.` The spacingof v clip angle'sffrom the' reinforcement` wforms a sleeve fori the'free passage of the latch 'I therebetweemiandalso acts as an anchoring means fori-the latch. fiApertures 8 are placed in the top plate inthesamevertical plane as the sleeved openingv between the clip angle 6 and the reinforcing member 15a yfor the purpose of allowing `a portion of the latch member Tito pass therethroughand engage withthe supporting longitudinal vbeamlmember.y Q
l The vertical adjustability of theY form lies inthe novel construction of the latch; 'I in combination with vthe angular transverse?reinforcing',member Be'and'clip 6 as will be noted from 'Figs. 3, 5,*and 6. The Llatchl comprises Va lip .portion 9, body portion I0 and tail member II.

. Oblongfopeningsl,"I1, and I8 are so arranged in the-transversreinforcing member 15a and the adjacent clip angle 6 so. asto 'coincidewith the holes I3' 'and I 4 "in 1 thelatchwhen' the latch is in the differentpositionsto engage the top cover plates. -Openings lI9 in the reinforcing member e'and clip'vangle `I5 are spacedapart" from the group f of oblong openings I6, II andiil 'so/.as to be 'in alignment with the' slot I5 of 1atch2'|.

To maintain the form in position a pivotal pin 20 is inserted through the openings I 9 of the reinforcement 5a and clip 6, and the slot linthe latch '1.
