`My invention relates to'foundations, composed of portable sections, for railroad signals and the like of substantial area and at the same time adapted to provide firmness; the various sections when properly assembled being firmly locked together.
My invention has for its object the provision of a sectional foundation composed of pre-cast reenforced concrete units which may be easily transportedto the place where the foundation'is to be erected; the respective sections being of such formation that they will not only provide interlocking relation with each other, but at the same time be interchangeable,'thus enabling` easy assembly of the respective units.
The invention also involves means whereby the assembled units maybe rmly locked together; the looking means beingv so arranged that accidental removal thereof is impossible. l f
The above enumerated objects as well as the advantagesinherent in the construction will all be fully comprehended fromtlie following detailed description of the accompanying drawing, wherein` p Figure 1 is an elevation of my improved foundation.
Figure 2 is a plan view thereof, with a portion broken away. ,Y
Figure 3 is a sectional view taken on the line 3-3 ofFigure 1 looking in the direction of the arrows. Y
Figure 4 is a perspective view of one unit of the foundation.
Figure 5 is a vertical sectional view show* ing a modified form of foundation, with intermediate portions broken away.
In the exemplification offmy invention as disclosed in the drawing, the foundation is composed of a plurality of precast reenforced ,concrete units of suitable size and dimensions in order that the respective sections may be portable and therefore easily handled and assembled. The foundation involves a bottom unit or slab indicated at which is shown in Figure 2 asv being substantially square and of size in keeping with the size of the foundation so far as width is concerned. The slab at suitable points, preferably in proximity tothe corners, is provided with openings extending therethrough as at 11 intended 'to receive a suitable rodv 12 of length commensurate with the height of the foundation to be erected so as to extend from the top unit or member ofthe foundation through to the bottom of the base slab or unit 10 in order that the respectivek sections may be securely bolted together when properly assembled. In the particular exemplification of the'invention as disclosed in the `lirst figure of the drawing, each aperture 11 in the bottom unit or slab terminates on the lower face of the unit 10 in a horizontally or right angularly disposed socket 13 adaptedto receive the bent end 14E of the rod 11; the socket 13 being of depth sufficient to permit the bent i end 14 of the rod to extend in a horizontal plane above the plane ofthe bottom of the slab in order that the latter may lie flush, as
indicated in Figure 3.
Superposed on the bottom unit or slab 10 and in spaced relation are a pair of precast reenforced concrete units 15, 15.- rllhe units f 15 are each provided with an aperture 16 disposed therethrough, to register with the apertures 11 in the bottom unit, for` the passage yof the rods 12. Superposed on the units 15,
15in spaced relation with each other and disposed at right angles to units 15, 15 are the additional units 17, 17 each of which is lilrewise provided with a pair of apertures 18 for the passage of the rods 12; and these units 17 have the two spaced units 19, 19 superposed thereon provided with apertures similar to the ones previously described and adapted to register with the apertures ofthe units therebeneath to receive the rods 12.
vrlhe units 19k are arranged at right angles to Cil countersunk as shown at 21 to receive the nuts 22 which screw onto the upper ends of the rods 12; the countersunk portion 21 being of depth suhcient to permit the nuts to lie beneath the upper surface of the top slab, as shown more clearly in Figure 1.
In the specific disclosure in Figure 1, the intermediate units, namely units 15, 17 anc 19 are each provided with transversely disposed channels or grooves, as more clearly shown at 23 in Figure 4, of width corresponding with the width of the adjacent units in -order that an interlocking engagement between the superposed units may be provided.
Instead of employing large'bottom and top slabs as shown in Figures l and 2, they may be sectional or may each consist of a pair of units identical with the intermediate units; that is to say'all of the units of the foundation may be of the construction disclosed in Figure 4,-which latter may be considered to represent the units 15, 17 and 19 in Figure 1,-of rectangular conguration provided adjacent the ends with the openings 18 extending from top to' bottom therethrough for the reception of the rods or bolts 12; the apertures or openings 18 being arranged in the channels or grooves 23, 23, formed in both the top and bottom surfaces of the units.
In order to make the units interchangeable and thus permit the same to constitute either bottom, intermediate or to'p units, each unit may be provided with the laterally disposed socket or groove 13 which connects with either the rod-receiving apertures 16 or 18 for the purpose of vreceiving the angularly disposed lower end 14 of the tie-rods and thus permit any one of the units to constitute the bottom or base portion of the foundation.
In order to properly maintain the hookbolts in place, the bottom sides of the units where they have the sockets or grooves 13 are provided with means partially embedded in the concrete with one end protruding therefrom so as to permit the protruding end to be bent over and across the bent ends 14 of the rods. In Figure 4 at the left hand end I disclose this means in the nature of a wire as shown at 24, while at the right hand end this tie means is shown in the nature of a fiat bendable strip of met-al 25; either form of said means may be employed. It is apparent that after the rods 12 have been passed of the rods while vscrewing on the nuts 22 at the upper ends will be prevented.
It is evident that where the foundation is composed of units like that disclosed in Figure 4, thus permitting interchangeability, the channels 23 on the upper surface will take the place of the countersunk portions 21, as these channels are of sufficient depth to permit the nuts 22 at the upper ends of the rods to lie flush with the upper surface of the uppermost unit; and it is also apparent that the foundation may be built to any desired height by employing a sufficient number vof units arranged in the criss-cross manner heretofore described; lateral movement of the respective units being prevented not only by the rods or bolts but alsoY byY the interlocking surfaces provided by the channels 23.
In Figure 5 I show a slight modification of the invention wherein the tie-rods 26 are shown threaded at both ends and the lower or bottoni unit 27 is provided with a flanged member or nut 28 which is embedded in the concrete slab 27; the flanged portion of the Y nut being'at the upper or inner end thereof. Like in the previously described construction, the top and bottom units or members of the construction shown in Figure 5 may be identical with the intermediate units which are similar to the intermediate units shown in the previous figures, namely with the opposite ends provided with the transversely disposed cut-away portions or channels 23 in order to permit interlocking relation between the respective units; the cutaway portions or channels being provided at the points where the units are cast with the bolt-receiving openings 16 in order to receive the tie-rods.` By reason of this construction, it is apparent that the nuts 29 at the upper ends of the rods 26 will be countersunk or located beneath the top surface of the upper unit 20a; or where the top unit is inthe nature of a slab, the rod receiving opening 16 is provided with the countersunk orifice as at 30 in Figure 5. The embedded member or nut 28 in the lower unit or slab 27 on its upper or inner face is dished as shown at 31; the dishing inducing or assisting a centering of the rod especially where the rods are inserted into place after the respective units have been put in superposed relation.
In order that the top and bottom members of the foundation may be easily handled while still desiring these members to extend through the width of the foundation in the nature of slabs, these members may be made v as terms of description and not as terms of limitation, as structural modiiications may be made without, however, departing from the spirit of my invention.
