Agent, or F irmAlvin Edward Moore 5 7 ABSTRACT Splicing means for connecting two wood piles, end-toend, to make a long pile for transfer of pile-loads to lower, stronger ground. The splicer comprises: at least one plate-like. substantially horizontal element adapted to lie between adjacent pile ends. with optional epoxy glue between upper and lower surfaces of this element and the upper and lower piles; and a central upright dowel member. extending above and below the plate-like element. This plate-like element is in the form of a disk in FIGS. 1 to 3 and 6 to 9; in FIGS. 4 and 5 there are two plate-like elements (the horizontal parts of angle irons, these irons being welded on opposite sides of the dowel); and in FIGS. 10 and 11, the plate-like element has two parts that are at angles to each other and integrally joined at their lower lines of junction (this angle plate being fixed to a V-shaped cut in the lower pile). Preferably, the splicer comprises other pile penetrating and anchoring elements that are fixed to the plate-like element, for example: the piece of six-inch pipe of FIGS. 1 to'7, extending around the disk (or angle irons of FIG. 4), driven into the upper and lower piles; the vertically-extending parts of the angle irons of FIGS. 4 and 5; the prongs of FIGS. 6 and 7, struck-out from the disk; the laterally placed, double-point pins of FIGS. 8 and 9; or the hammer-driven nails or spikes of FIGS. 10 and 11. And preferably the upper pile section of the composite pile is within a tightly clamped metal band, and is at least 30 feet long.
12 Claims, 11 Drawing Figures PATENTEB AFR 91974 Riga/47 m WW k was FILE SPLICER Because timber piles are often required in lengths too long to be made from single tree trunks there is need for an efficient splicer to join ends of two piles, thus forming a long pile, able to transfer loads to deep, stronger ground. another advantage of such a composite pile is that the lower pile may be of untreated wood, while the upper pile (mostly above the water table and thus vulnerable to rot) may be treated with wood preservative. In view of these facts, some objects of this invention are to provide: (1) a pile splicer having elements that will efficiently penetrate upper and lower piles, anchoring them together; (2) a splicer comprising a metal plate, fitting between and against ends of two piles, and pile-penetrating elements above and below the plate; (3) a splicer having an upright tube, adapted to be driven into end portions of end-joined piles and pile-anchoring elements, fixed to the tube, one of these elements being an upright polepenetrating dowel, longer than the tube; (4) a splicer having an angled plate and nails or spikes driven into adjacent V-jointed piles; (5) a composite pile comprising a pair of upright, end-to-end piles, the upper one of which has a factory-drilled hole, and a splicer having elongated, upright, integral dowel portions, one pressed into the pre-drilled hole and the other forced down into an on-the-site-drilled hole; and (6) a fastening device for forming a joint between ends of piles or the like having a central dowel means and angle irons fixed to the dowel means.
Other objects of the invention will be apparent from consideration of the following specification and the accompanying drawings.
In these drawings:
FIG. 1 is an elevational, exploded view, partly broken away, of upper and lower piles and a splicer by which they may be joined;
FIG. 2 is a mostly plan view from the sectional plane 2-2 of FIG. 1;
FIG. 3 is an elevational view, partly broken away, showing the composite pile, comprising two pile sections that are connected by the invented splicer;
FIG. 4 is an elevational, exploded view, partly broken away, of two piles and a second form of the invented splicer;
FIG. 5 is a mostly plan view from the sectional plane 2-2 of FIG. 4;
FIGS. 6 and 7 are views similar to FIGS. 4 and 5, illustrating a third form of the splicer;
FIG. 8 is a vertical, sectional view of two piles joined by a fourth form of the splicer, with the resulting composite pile shown as being driven into the ground;
FIG. 9 is a top plan of the splicer of FIG. 8;
FIG. 10 is a vertical, sectional view of two piles joined by a fifth optional form of the invented splicer; and
FIG. 11 is a plan view of the angled plate and central dowel element of FIG. 10.
In each of the forms of the invention the splicer comprises: at least one metallic, plate-like element (optionally the disk 1 of FIGS. 1 to 3, or each of the substantially horizontal parts 2 of the angle irons 4 of FIGS. 4 and 5, the disk of FIGS. 6 and 7, the disk 6 of FIGS. 8 and 9, or the angled plate 7 of FIGS. 10 and 11); central dowel means, fixed to the plate-like means, comprising a pin 8 extending upward from the plate-like element and a pin 9, extending down from the said element (these pins preferably being integral, forming a single elongated dowel member); and other pileanchoring means (the tubular element 10 of FIGS. 1 to 7; or the sharp-pointed pins or dowels 12 of FIGS. 8 and 9; or the nails or spikes 14 and 16 of FIG. 10); and- /or optional epoxy glue (liquid cement or putty) that may be placed on each side of the plate-like means). The plate-like elements of FIGS. 1 to 3 and 6 to 9 have holes 18 which further aid in anchoring the pile ends together when epoxy glue is used, for the glue goes thru the holes and cements the ends of both piles to each other, as well as to the plate. At least the lower tip of the pile 38 is clamped within a tightly crimped steel band, 17. Optionally, the butt of the lower pile 34 (at the joint) may be thus clamped.
The elements 8-9, 10 and 12 are welded to the platelike means. The tube 10 of FIGS. 1, 2, 6 and 7 (preferably a piece of six-inch standard pipe, approximately eight inches long) is welded to the disk (1, 5), preferably all around the edges of the disk. In FIG. 4 the arcuate ends of the oppositely extending angle irons 4 are welded to the inner curvature of the tube. Preferably, the horizontal parts 2 of these angles are 1 /2 inches wide; and their vertical parts 20 and 22 are 2% inches deep. These vertical parts, in addition to the tube 10, serve as pile-anchoring means, for during the first blow of the pile hammer on the upper pile the part 20 penetrates the lower pile and the part 22 penetrates the upper one.
In FIG. 6 the plate-like means (the disk 5) has prongs 24 and 25 that are cut out from it and bent into vertical positions, forming the holes 18 in the process. The prongs 24 penetrate the upper pile, and the prongs 25 penetrate the lower pile.
In FIG. 8, the pile-penetrating pins 12 are extended thru holes in the plate 6 and welded there at each pins middle portion. As in the splicers of FIGS. 1, 6 and 10 the central dowel means 8-9 preferably is a single metal dowel, extended thru and welded in a hole in the platelike element. The dowel means 8-9 of FIG. 4 is also similarly welded at its middle portion to the vertical elements '20 and 22.
In FIGS. 10 and 11, the angled plate 7 approximately fits in the V-shaped cut in the lower pile. This steel plate is sufficiently bendable at its middle line 26 for its parts 27 and 28 to move under pile-hammer blows into tight contact with the bottom V-shaped cut and the angled lower end of the upper pile. The pile 38 preferably has a minimum length of 30 feet. Therefore, the joint is within deep, strong ground.
METHOD OF MANUFACTURE This invention comprises a method of making the composite, two-part, elongated pile, having the following steps:
l. The lower pile 34 is driven by the hammer of a pile driver until the top end of this pile is of satisfactory distance above the ground for working on it for example about waist high.
2. Drilling the holes 30 and 32 in the two piles. Preferably these bores 30 and 32 are of slightly less diameter than the major diameter of the dowel means; and in assembly the dowel thus penetrates and compacts the wood around the hole, insuring a tight fit and pole-anchoring friction. For further aid in the pile-guiding and pile-anchoring functions of the dowel means it preferably has a minimum diameter of three-fourths of an inch. When it has this diameter, for example, the holes 30 and 32 preferably have a diameter of eleven-sixteenths of an inch.
3. The dowel element 9 isinserted into thehole 32, and this element is driven into the hole, until the bottom edge of the tube contacts the top of the pile 34 (or, re FIGS. 8 to 11, until the plate-like element, 6 or 7, contacts this top). In driving the pin 9 of FIG. 8 a heavy sledge hammer is preferably used, striking the somewhat blunt upper end of the pin 8. In each form of the invention the dowel means optionally may have ends that are entirely unpointed, as exampled in FIGS. 1 to 3, or have end portions that are sufficiently pointed to provide easy access of these ends into the bores, these end portions being slightly pointed but having blunt, planar tip surfaces 36. For economy of manufacture, the currently preferred dowel means is an unpointed round steel rod of the type illustrated in FIG. 1.
4. The upper pile section 38 is lowered by the pile A driver, and this section is adjusted until the bottom edge of the hole 30 is over and contacting the dowel element 8. I
5. The pile hammer is actuated to drive the pile 38 down over the pin 8, driving other pile-anchoring meansthe tube 10 and/or the plate-like element and its connected auxiliary pile-penetrating elements (20 and 22, or 24 and 25, or 12) into their pile-anchoring positions.
6. The pile driver continues driving the composite pile until its top is in the desired position relative to the ground surface.
The above step (2) preferably comprises two parts: (2A) the holes 30 are pre-drilled in the plant that makes the pile sections; and (2B) the holes 32 are drilled after the pile sections 34 are driven into their junction-forming positions. Also preferably: the following step is taken before (28): the top of the piledriverblunted section 34 is saw-cut into the planar shape of FIGS. 1 to 8 (or the V-shape of FIG. 10); and when the splicer is of the type of FIG. 10, the following step is taken between the above steps (3) and (4): the nails 14 are driven; and also in the case of FIG. 10, the following additional step is taken between the above steps (5) and (6): the nails 16 (which may be spikes) are driven into the two piles, above the upper edges of the steelplate parts 27 and 28. Preferably the nails 14 are 60- penny common nails and the nails 16 are barn nails, longer than the GO-penny kind.
Another optional and preferable step in the method of manufacture comprises the placing of liquid or viscous epoxy cement between the substantially horizontal faces of the plate-like element and the adjacent surfaces of the piles 34 and 38. In the case of FIG. 10, this cementing step results in the glue layers 40 and 42 above the upper edges of the elements 27 and .28, as well as the cement layers between these elements and the pile sections 34 and 38.
