Description
D. M KNIGHT Jul 21, 1959 PILE COPING Filed July 12, 1954 ATTORNEYS United Sttes Patent if This invention relates to a pile coping, and has as its primary object the provision of an improved, prefabricated sectional pile coping which may be readily transported to the place of use, and installed with ordinary field working equipment with a minimum of effort and difficulty.
An additional object of this invention is the provision of such a pile coping comprised of a pair of stepped separable sections which may be readily handled, and which are adapted to be clamped together tightly about the pile head.
Still another object of the invention is the provision of a device of this character which may be preformed readily to accommodate irregular spacing of piles, such as may occur through inadvertence or irregularity in the pile driving.
An additional object of the invention is the provision of a device of this character provided with means whereby various sizes of piles may be readily accommodated.
Still other objects reside in the combinations of elements, arrangements of parts, and features of construction, all as will be more fully pointed out hereinafter, and shown in the accompanying drawings, wherein there is disclosed a preferred embodiment of this inventive concept.
In the drawings:
Figure 1 is a side elevational view, partially in section, disclosing one form of pile coping embodying features of the instant invention, certain concealed parts thereof being indicated in dotted lines;
Figure 2 is a top plan view of the structure of Figure 1, parts thereof being shown in section, and parts being indicated in dotted lines;
Figure 3 is a sectional view taken substantially along the line 3--3 of Figure l, as viewed in the direction indicated by the arrows; and
Figure 4 is a sectional view taken substantially along the line 44 of Figure 1, as viewed in the direction indicated by the arrows.
Similar reference characters refer to similar parts throughout the several views of the drawing.
Having reference now to the drawings in detail (Figure 1), there are disclosed at a plurality of piles, which in the illustrative embodiment herein shown are hexagonal in shape, but which may be of any other polygonal or circular shape if desired. The pile coping of the instant invention is generally indicated at 11, and is adapted to extend transversely of a roadway bridge or the like and cap a series of aligned piles.
The coping 11 (Figure 2) is comprised of two sections 12 and 13 (Figure 3) which for descriptive purposes may be termed the top and bottom sections. Section 12 includes a bottom face 36, a side face 37 extending perpendicularly upwardly from the bottom face 36, a top face 17 extending perpendicularly away from the side face 37 and overlying the bottom face 36 in parallel relation thereto, and a step face 14 extending between and connecting the top face 17 and the bottom face 36. The
Similarly, portion 13 is provided with a plurality of longitudinally extending reinforcing rods 24, about which are positioned transverse reinforcing wires 25, the latter terminating above the top of recesses 20.
At suitable spaced intervals, longitudinal holes 30 are positioned in aligned relation and extending completely through the side walls of members 12 and 13. The holes 30 are adapted for the reception of securing bolts 31 provided at their extremities with nuts 32.
The ends of the pile copings may be suitably beveled as indicated at 35, for suitable positioning of ancillary members comprising components of the bridge structure.
In the assembly of the device, it will be readily apparent that the piles 10 are first driven, and the pile copings 11 are then cast in two sections, a suitable spacing medium being provided for the separation of the two, and the apertures 20 being suitably spaced in conformity to the already driven piles 10. The coping is then transported to the bridge site, and lower section 13 which, it is to be noted, contains the greater portion of each of recesses 20, suitably positioned over the piles. Upper section 12 is then positioned in face-abutting relation with section 13, with step 14 seating on step 15, and bolts 31 passed through the bores 30 and suitably tightened by means of nuts 32 thus clamping the pile 10 between the lower section 13 and the upper section 12 of the coping. Additional cement is then poured through holes 21 for the coping assembly.
A j I 2,895,302 p r,
purpose of completely filling the recess 20 above each pile 10.
After the concrete is solidified, it will be readily apparent that there will be provided a complete pile and pile From the foregoing, it will now be seen that there is herein provided an improved prefabricated separable pile coping which may be readily adapted to a Wide variety of sizes and spacings of piles, which due to its two-piece construction may be readily and easily handled and placed in position, and which thus accomplishes all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.
As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.
