This invention relates to supports and more particularly to temporary supports for elevated structures, although it may be used with equal advantage for other puposes.

It contemplates more especially the provision of novel means constituting related standard units which may be readily assembled with ease to providea temporary adjustable support to sustain structures in position during the erection or formation thereof.

Numerous expedients have heretofore been employed to temporarily sustain plastically formed elevated structures, such as floors, but these have not proven entirely satisfactory,

" in that they must necessarily be especially erected to meet particular conditions. In view thereof, the known methods are eX- tremely laborious and expensive, it beingnecessary that the means heretofore proposed for the purpose set forth, be partially or wholly destroyed to eifect the removal there* of, thereby rendering them of little value for repeated use.

One object of the present invention is to simplify the construction and improve the operation of devices of the character mentioned.

Another object is to provide a temporary, support such as a beam or column constituting standard units which ma be readily assembled and dismantled Without impalring their utility.

A further object is to provide adjustable means for su porting structures Whichl are inexpensive, urable, and of light construction. i

A still further object is toprovide means which are preferably adjustable and capable of association and disassociation with other means to serve as a stabilizer therefor.

Other objects and advantages will appear from the following description of an illustrated embodiment of the present invention.

In the drawings:

Figure 4 is a plan view of a constituent unit disclosed in Figures 2 and 3.

Figure 6 is a sectional view taken substantially alonu line VI-VIof Figure 4. Figure is an enlarged detail sectional view takensubst-antially along line VIL-VII of Figure 3. i n

Figure 8 is a fragmentary sectional view similar to Figure 2, showing a further use o the present invention. In the particular embodiment of the present invention which hasherein been selected for illustration, the structure is shown in connection with the construction of an elevated door 10 formed in the usual manner from plastic material such as concrete of standard consistency. `Floor pans `11 of standard construction, are suspended in an elevated position to receive the plastic material which is retained therein prior to `and during the setting thereof. Disposed below the adjacent edges of the pans 11, are the substantially rectangular" plates 12 `preferably of sheet material which are maintained in position by the centering or supports to be hereinafter described.

In order to properly support the floor pans 11, suitable shores constituting standard units are provided which arereadily adjust-f able and capable of assembly with ease to meet varied conditions without impairing their utility. The shores in this instance, are composed of four sections, 13, 14, 15, and 16 referably of sheet material, each sectionbel ing slitted transversely along a `median line as at 17 (Figure 4) so as to permit the slitted portion to be bent transversely along a longi tudinal line to define oppositely extending wings 18 and 19, which, 1n the present embodiment, project normally of the base 20 or unslitted portion thereof. The wings 18 and 19 of each section terminate in an upstanding portion 21 and 22` (Figure 6), respectively,` which have normally projecting flanges 23 and 24 disposed outwardly an parallel to their respective wings 18 and 19. To enable the sections 13, 14, 15, and 16, in this instance four, to be readily assembled to define a light `but rigid member capable of sustaining a load, the base 2OandV flanges 23 and 24 of each section are apertured along` the length thereof as at 25 and 26, respectively.

i With this arrangement it is possible to comlation to permit the insertion of a fastener through the aligned apertures and E26 provided therein. The fastening means, in this instance, consist of a metallic Wire 27 twisted at intervals to provide loops 28 spaced to Vcorrespond With the spacing of the apertures 25 and 26. As shown, the loops 28 are projected through the aligned apertures provided in the adjacent sections, thereby effectively secur ing the complemental sections together, there being suitable means such as the nails 29 inserted in the loops 28 to prevent accidental Withdrawal thereof and consequent displacement of the sections.

W ith the arrangement of parts above described,`it will be apparent that the ulasteninpmeans may be readily removed, and the sec tions rendered longitudinally extensible to provide a shore of any desirable length Within the limits detined substantially by the suinmation of the lengths of the complemental sections. To rigidity and stili-'en the shores, fillers are provided Within the tubular portions thereoiI to enable it to carry appreciable loads. The fillers, in this instance, consist of Wooden planks 30 of standard cross-sectional dimensions Which are inserted therein after being cut to the desired length. lt is to be noted that the sections which en'ibrace the fillers are extensible independent ther-eet and may be repeatedly used, it only being; necessary to adjust the length thereolE to meet varied conditions.

Metallic plates 3l are superimposed on the shores in confronting, spaced relation with the plates lf2, supra. Interposed between the plates l2 and 3l, are beams embodying fea tures of the present invention. The beams constitute standard sections, in this instance, identical in construction to the sections enr ployed to produce the shores, supra, the i'ormer comprising a mid-section 32 substantially identical tothe shores. Positioned Within the mid-section, are the fillers 30 constituting separateplanlrs Which define a dividing line co incident With longitudinal median `line of the sections whereby the latter may be separated therealong to receive end sections as will hereina'fter appear. It is to be noted that in this instance the complemental sections are secured together by means of the rivets 33, it being obvious that any other suitable fastening means may be employed for the purpose set forth.` Y

The end sections 3l and 35, in the present embodiment, serve to stabilize the mid-seo tions so as to constitute a temporary beam to support the floor pans as is apparent from the showing in Figure l. Each comprises a pair of complemental units ofthe type hereinabove described, which have their adjacent base portions 2O inserted intermediate' the contrentine)l flanges 23 and 2l (Figure 2) which are secured together and maintained in position by the fasteners 33 or preferably by other appropriate 'fastening means, such as the Wire 27 (Figure 7) having spaced loops 28 projecting through suitable apertures Qi? provided in the base of the units constituiting,l the end sections 3 and 35. The ilanges 23 and 2e of the end sections Sli and are liz-ed in any suitable manner to the soliit plates lil and 3l, respectively, the flanges of the section 34 being secured to the adjacent edges oit the licor pans ll by appropriate Ytasteners such the rivets Sli which extend through aligned apertures provided in the il: nges, and Llei, and the setlit plate l2, Will be understood from the showing in Figure 2. rlf he Wings 18 and lil of the end sections del and 35 are spaced from the plates l2 and 3l, respecti ely, owing to the opstanding :flanges and 22 oit the standard units so to receive therebetween iiller 3? preferably of Wood such as planks identical in size and confor-inlog in shape 'with the lill/ers 30, thereby rigidiliying the beam structure and rendering it stable to enable it to sustain appreciable loads,

It is iniportant to note that the beams co1npriasinggl the midsection 32 and end-scctions 84- and 3:3 are extensible longitudinally therel l much the saine manner as the shores de a Jin,

. .L scribed hereinabove, so that they may be varied and adjusted sustain structures at any desired elevation and of various spreads. hviousiy, after the plastic struc ure such as the licor l0 has set suii'iciently so that its in 'tornai reinlorcements can properly support the saine, the shores and beams may be dismantled Witiout impairingi their utility for further use, th y being readily assembled 'for repeated use.

lt vvill thus be apparent that a beam embodying features ol the present invention is composed of standard units oi' the type eniployed in the shores thereby enabling the units tofbe freely interchanged which requires a minimumamount ci units lto produce suiiicient supports for any construction.

The modified structure disclosed in Figure 8 is similar to the beam construction described above, save that in this instance, the mid-seo tion 32 is omitted and the bases 20 ot the end section secured together by any suitable means such as the fasteners 88 disposed along the length thereot' to maintain the end sections 3Ll and 35 in the desired relation, they being especially adaptable to be disposed in a vertical position adjacent sectional lagging 39 specifically described in my co-pending` application, Serial No. 126,141l. Suitable struts such as the Wires 40 are secured at one eXtremity thereoi' to the section 35', and at their other extremity to the spacing,` bands ll which project through the lagging; 39 in manner more fully described in the above identified cio-pending applicationV li/Vith this arrangenient of parts the stresses created by the plastic material conlined Within. the lao'fring 39 bei-'ore the setting,l thereoi is reduced to a Sii minimum due to the external reinforcing feature of the stabilizing structure constituting the sections 34 and 35. Obviously, section 35 may be omitted and the struts associated with the section 34 to maintain it in adjacent contacting relation with the lagging for the purpose set forth. It is to be understood that these external reinforcements are vertically adjustable and can be applied to any portion of the lagging wherever the stresses and strains appear to be appreciable.

I am aware that many changes may be made, and numerous details of the construction varied through a Wide range Without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:
