alike. On the other hand when more than one beam is required to span the space only that end of the beam to anchor' into the wall of the building willbe so formed, the other end of the beam being formed according to the end illustrated in Fig. G.
The modified form of beam end illustrated in Fig. Yl is used when it is desired to add strength to the floor to take up exceptional stress, this form of end differing from that illustrated in Fig. G in that the pocket 13 is inverted by extending the beam top 2 'to ccincide with the extended ends of the webs 3, and omitting the extension l of the transverse wall base.
lfl a very cheap structure is desired and one not likely to be subjected to heavy loads, the anchoring members and end walls may be omitted and the beams formed of inverted channel shape in cross section shown in Fig. Ll, with the inner and outer sides of the top, and webs parallel with each other, and this form, with the addition of the end walls serving as bases, can be used to advantage for floorings in buildings in which Y steel I beams are utilized as main bearei's.
iin example of one use is shown in Fig. 1l in which the beam end walls rest upon the projecting fiange of the I-beain, the space between the end walls and the I-beam channel being filled in with concrete or cement mortar or the like.
The reinforcements I prefer to use consist of longitudinal side rods or bars 14 bent back upon themselves with their ends bound together as at 15. These side rods are. enibedded in each of the lower parts as well as in both sides of the upper of the webs, lengthwise thereof and are secured` together by a series of transverse stirrups 16 fastened to the rods in .any preferred manner and spaced diminisl'iingly from the centre towards the ends ofthe rods, such rods with the stirrups presentinga skeleton v.frame of substantially inverted U-shape in cross section. The lower portion of any ldesired number ol." the stirrups are provided with fastening clips 17 extending downwardly, the purpose of which will be hereinafter explained.
ik typical method of forming the beams is illustrated in Fig. 8 which shows the successive steps followed. A platform of suitable material sueh as wet sand, indicated at is provided on which the outer sides of the mold frame 19 are laid, after which concrete sufficient to form a first layer or base Q() pouredin. rThe skeleton reinforcements indicated at 2l are then pressed into :the layer of concrete, the webs being uppermost.V A second layer of concrete 2Q, is poured in to cover the top of the reinforcements andform the roof of the inverted channel. after which the mold frame boards Q3, to forni the channel webs and those for the beam ends (not shown) areplaced in position and additional concrete poured in to completely envelopthe skeleton reinforcements. lt will be noted that the mold boards for the sides of the beam, both inner and outer, are longitudinallyT outwardly curved as at 2t, the curvatures being provided to give the fiares to the sides of the beam webs. Y
Before the concrete has fully set transverse openings Q5, the purpose of which will be hereinafter explained, are formed through the extended portions of the webs ,3, at such points that the openings in the webs of all beams will register; and at the same time should accommodation be needed for water pipes or the like such may be. provided for by forming openings at suitable points in t-he beam.
Figure 2 illustrates the manner in which the flooring is laid to cover a space too large to be spanned by a single beam length. The beams are laid side by side in lines with the end formed according to Fig. 6 resting and anchoring into the building. walls and the inner ends, formed according to Figure 5, rest on the customary intermediate walls oiI main beams 26. The beams in one line are laid in staggered relation to those in the other line with the projecting webs of one line engaging with or fitting within those of the other line.
In order to prevent lengthwise displacement of the beams and for strengthening purposes, meta-l rods or bars 27 extending the full width of the fiooring are inserted in the transverse openings 25 in the web ends, such rods being fastened in any preferred manner to the reinforcing rods 2 of the webs. lVedge shaped strips of wood, or other suitable material, indicated at 28, are laid length wise between the bea-nis and carried by the outer flared edges of the latter .and serve as a base for the concrete or cement mortar fillingbetween the beams 'aswellas a inediuni from which wire or other materialV to form a, ceiling may be streteliedrand the clips l serve to connect the ceiling and the reinforcement formed thereby to the reinforcement within the beam. Spaces are left below the wedge strips 28 to accommodate concrete or mortar cement filling, which keys the ceiling to the flooring base.
The longitudinal spaces between p the beams, the spacesV between the ends of the beams and within the recesses and between the beam and side walls and main beams of the building are then filled in with concrete or cement mortar this having the effect of anchoring the beams together and to thewalls ofthe building and forming a complete inonolithic structure. To provide additional strength at the points of greatest stress, usually theends of the beams, any
suitable uantity of small sized metal scrap may be ac ded to the-concrete mixture at such points. l.
there a `ceiling-is desired such may be formed of expanded metall :29 or other reinforcement stretched to the wedge strips 28, as alreadystated, and connected bythe clips 17 to the reinforcements inthe beams, the expanded metal beingafterwards filled in with cement or other mortar and finished ol'l' in any desired way. The` addition of a. ceiling connected to the bottom of the fiooring as just described has ythe advantage by its connection to and close co-opcration with thereinforcement within the beams, of imparting additional strength to the flooring. The flares on the lower inside parts of the webs may serve to accommodate bases, such as metal plates, wooden blocks or the like which can bewedged in andV from which shafting, belting or the like may be hung.
From the foregoing vit will be apparent that the beams, whichinay be of any desired dimensions and reinforcements, may.
be made wherever may be most convenient to the work Yor building either in the shop or adjacent the building being constructed.
While I have illustrated and described the interior of the beam as of inverted channel shape in cross section and the exterior of key-stone shape in cross section, itis obvious that variations of this formation may be made with advantage and without departing from the spirit of my invention. For instance, when an exceptionally heavy load is to be carried or an economy of vertin cal space is desired, the beam interior could be made of arci-form in cross section as shownin Fig. 9, or the points of junction of the inner sides of the webs and the top could be curved as shown in Fig. 10.
