(Cl. 61-56) ABSTRACT OF THE DISCLOSURE A reinforcing concrete pile with an H-beam in the center thereof projecting slightly above the concrete body to receive the driving impacts of a flanged driving hammer head, and with a boot or shoe on the lower end of theconcrete body for reinforcing the lower end of the pile and concentrating the soil at and adjacent thereto.
This invention relates generally to the art of piling and more particularly to a reinforced concrete pile.
Piles are used to support or form foundations for structures such as buildings, tanks, piers, bridges, conduits, wharves and the like by inserting them into or through surface strata far enough to obtain a solid support for the principal structure. The present invention is concerned with pile foundations for structures in loose earth, made earth, shell'earth, said earth whether stationary or shifting and similar soft or wet soil. A I In driving concrete piles if the concrete is subjected to the successive impacts of the driving tool it may shatter or fracture in the driving operation. It is accordingly a primary object of the present invention to provide a reinforced concrete pile wherein one of the metal reinforcing members projects above the top end of the concrete and absorbs the driving impacts of the driving hammer.
' Another object of the invention is to provide a reinforced concrete pile With an H-beam having projecting lugs in the center of the pile serving as reinforcing agents, the top end of the H-beam adapted to receive the driving impacts of the driving hammer.
Still another object of the invention is to provide a reinforced concrete pile that is especially well adapted to' withstand both tensional and compressional longitudinal forces as well as lateral stresses.
A further object is to provide the concrete pile with a boot or shoe that is capable of at the same time reinforcing the lower end of the pile and concentrating the soil at and adjacent thereto. Yet another object is to provide a boot or shoe of maximum strength and minimum weight.
It is also an important object of the present invention according to a modification thereof to provide in a sectional pile a connnecting device or coupling to be placed on the upper end of the lower of two pile sections and to receive the lower end of the upper section and hold said upper section in proper position with reference to the lower section.
With these and other objects in view as will appear hereinafter, my invention consists ofcertain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference 7 being had to the accompanying drawing forming a material part of this disclosure, in which FIG. 1 is a top plan view of a reinforced concrete pile embodying one form of my invention.

FIG. 9 is a cross-sectional view taken on the line 9-9 of FIG. 8.
FIG. 10 is a top perspective view of the coupling device or connector used for joining the sections of FIG. 8.
FIG. 11 is a view similar to FIG. 1 of a reinforced concrete pile embodying a still further modified form of the invention.
FIG. 12 is a similar view of a reinforced concrete pile embodying yet another modified form of the invention.
FIG. 13 is a vertical sectional view similar to FIG. 8 through the joint of another modified form of reinforced concrete pile.
Referring now in detail to the various views of the drawings, in FIG. 4 a reinforced concrete pile embodying one form of the invention is shown and designated generally at 10. The pile 10 is shown partly driven into the ground 12. The improved pile 10comprises an elongated straight sided body 14 of concrete with flat top and bottom ends 16 and 18, respectively. A metal H-beam 20 is embedded in the center of the body. The H-beam extends the length of the body and protrudes slightly above and below the top and bottom ends of the concrete body as indicated at 22. The reason for this slight protrusion will be more fully described hereinafter.
In accordance with the invention, metal angle lugs 24 are welded to the web portion 26 of the H-beam and project laterally being embedded in the concrete of the body as shown most clearly in FIGS. 2, 3 and 4.
According to the invention, both ends ofthe concrete body 14 of the pile are formed with central H-shaped recesses 28 around the ends of the H-beam 20' and being of such dimensions so as to leave a clearance 30 on each side of the Web portion 26 and a clearance 32 on the outside of each flange 34 of the H-beam as best seen in FIG. 1. The purpose ofthese clearances will be more fully described hereinafter.
Another important feature of the invention is a driving boot or shoe 36 that is slipped over the bottom end of the H-beam 20 covering the bottom face 18 of the pile body 14, thereby forming an extension of the body. The boot or shoe 36 is made preferably of one piece of cast steel but may be made of other suitable material such as cast iron or other alloyed metals. The boot or shoe has a solid conical shaped body 38 tapering to -a point 40 and having a flat top surface 42;as viewed at the bottom of FIG. 4, with a peripheral upstanding flange 44 to protect the lower outside edge of the pile body 14 against driving action. At the center of the top surface 42, there is a pair of closely spaced perpendicular plate-like flanges 46 and closely spaced at right angles from the ends of these flanges 46 there are'similarly shaped perpendicular plate-like flanges 48. The space 50 between the ends of flanges 46 and the inner faces of flanges 48 is sufllciently wide to receive the lower endsv of the flanges 34 of the H-beam 20 and the space 51 between the flanges 46 is sufliciently wide to receive i the web 26 of the H-beam, as best seen in'FIG. 4.
The recesses 30 and 32 in the bottom end of the body of the pile are sufliciently deep, wide and long to receive the plate-like flanges 46 and 48 to avoid contact with the concrete constituting the pile body 14. On each side of the pair of flanges 46 there are recesses 54 which ar provided for cost saving only.
The reinforced concrete pile 10 is adapted to be driven into the soil 12. as shown in FIG. 4 by means of a driving hammer head 56 having a circular body or base 58 with a substantially square-shaped enlargement 60 as shown in FIGS. 4 and 5, and centrally of the enlargement there is a pair of closely spaced plate-like depending flanges 62, 62. Along opposed sides of the enlargement 60, there are depending plate- like flanges 64, 64 spaced as shown at 63 from the ends of the flanges 62, 62 sufficiently to receive the top ends of the flanges 34 of the H-beam as shown in FIG. 5. The space 61 between the flanges 62, 62 is suflicient to receive the web 26 of the H-beam.
In operative position as shown in FIG. 4, the enlargement 60 of the hammer head 56 seats on the top end edges of the flanges 34 and the web 26 of the H-beam, thereby spacing the circular body 58 of the hammer head away from the top concrete surface of the body 14 of the pile, and spacing the bottom end edges of the flanges 62 and'64 away from the base of the recesses 30 and 32 shown at the top of FIG. 4. Accordingly there is a metal to metal drive from the hammer head surface 60 to the H-beam web 26 and flanges 34, and the concrete body 14 is therefore protected from damage. The boot construction affords an easy start for the driving operation of the pile and afiords maximum support for the pile during driving, as well as reinforcing and protecting the lower end of the pile and preventing it from splitting or cracking. This is due to the metal to metal contact of the lower surfaces of the H-beam web 26 and flanges 34 bearing upon the top flat surface 42 of the boot in the spaces 50 and 51.
In FIG. 7 a modified form of boot or shoe 10 is shown and differs from the boot or shoe 10 of FIG. 4 in that the solid body 14 is straight along its bottom side and is formed with a curved recess 66 providing a dish-shaped body with a cutting edge 68. The recess 66 draws in and compresses the soil within this recess when the pile is driven.
FIG. 8 illustrates another modified form of reinforced concrete pile 10 which pile is sectional, two adjoining sections 70 and 72 being shown and joined by a coupling device or connector 74. The pile sections are similar in construction to the body of the pile 10 as shown in FIG. 2 and similar reference numerals are used to indicate similar parts.
The coupling device or connector 74 comprises a metal casting consisting of a circular body or base 76. Projecting from each side of the body or base, the top side and the bottom side as viewed in FIGS. 8 and 10, there is a pair of closely spaced plate-like flanges 78 disposed centrally and transversely thereof. At each end of the flanges 78 and spaced therefrom there is a similarly shaped plate-like flange 80. The spacing between the lengths of the flanges 78 and that between their ends and the inner faces of flanges 80, and their lenghts, widths and depths are exactly the same as for the flanges described and illustrated in FIGS. and 6 in reference to the hammer head 56 and boot or shoe 36.
surface 40 of the boot or shoe 36. These driving forces are then delivered from the bottom surface of the coupling or connector 74 to the top flange and web surfaces of the H-beam in the lower pile section 72, and through it to the lower end to drive the boot and shoe 36, shown in FIG. 4, into the ground. It is hereby readily seen that the driving forces required to force or drive a multiple sectional pile as illustrated in FIG. 8, whether two or more sections, into bearing position are accomplished by metal-to-metal forces without disturbing or fracturing the piles concrete body formation.
In operation, the lower pile section 72 when driven into the earth has the coupling device 74 placed on the upper end of the section with the flanges outside the flanges 34 of the H-beam and with the flanges 78 on the inside of said flanges 34 and on opposed sides of the web 26. Then the upper section 70 is lowered with the flanges 34 of the H-beam placed between the flanges 80 and 78 of the coupling device or connector taking the position as shown in FIG. 8 thereby aligning the H- beam flanges and webs of both pile sections 70 and 72.
It will be evident that the coupling device or connector 74 serves to provide a strong and effective connection between the adjacent ends of the pile sections 70 and 72.
The modified form of reinforced concrete pile 10 shown in FIG. 11 differs from the concrete pile 10 of FIG. 1 merely in that reinforcing rods 82 are provided in the body 14 of the pile.
The modified form of reinforced concrete pile 10 shown in FIG. 12 is similar to the pile 10 except that the body 14 of the pile 10 is multi-sided.
Referring to FIG. 13, another modified form of concrete pile is illustrated. In this form, a modified coupling or connector 74 is shown which, in all respects, has all the features and construction of the coupling or connector 74 of FIG. 10 including its circular body or base 76 with the exception that at the periphery of the circular body or base 76 there are upward and downward extending flanges 84 and 84, respectively. These flanges are provided to create more stability and rigidity between the pile sections 70 and 72 and protect their lower and upper concrete edges. With this modified form of coupling or connector, the driving forces for the assembled pile are delivered from the upper pile section 70 through the H-beam to the lower section 72 by means of the circular body or base 76 as already described above in view of the coupling or connector 74, FIG. 10.
All features and construction of pile sections 70 and 72 are exactly the same as those shown and described in reference to FIGS. 1, 2 and 8, and similar reference numerals are used to indicate similar parts. The driving forces will be delivered in like manner to force the pile into the ground to its required depth without distraction or damage to the main concrete body 14 of the pile structure.
In this pile construction, the very slight protrusion of the H-beam reinforcement as shown, and the slight clearance between the lower surface 18 of the pile and the flat surface 42 of the boot or shoe 36, FIG. 4, and the very slight clearance 45 shown between the two top and bottom sections of a multiple sectional pile, FIGS. 8 and 13, and the connector 74 or 74 will be reduced to a minimum due to the driving pressures directed upon the surfaces of the flanges and webs of the H-beam 2'0 reinforcement of the pile structure. It must be realized that some amount of swedging action of the H-beam end surfaces area, the web and flanges, will take place due to the driving force of the hammer head 56 at the head of the pile, and at its base where it is in contact with the boot or shoe 36 as illustrated in FIG. 4. The same swedging action will take place between the lower and upper ends of the H-beam in the upper and lower sections 70 and 72, 70 and 72 as shown in FIGS. 8 and 13, respectively. This swedging action will cause the lower end 18 of the concrete body 14 of the reinforced concrete pile sections to recede to within close contact of its end surfaces to its next preceding unit or member without cracking the lower edges or surfaces of the concrete body 14 of the pile or pile sections in no matter Vi hat sequence they may be used, singular ly 'or" in the plural to p .7 i. v,
The clearance 45, FIG. 4,, between the bottom surface 18 and the flat top surface 42 of the boot or shoe 36 will v.be eliminated'due to the driving forces upon the H-beam, and in view of FIGS. 8 and 13, the driving force "swedging action upon the surfaces of the H-beam 20 ends will also close up the space 45. This swedging action due to the driving forces upon the pile or connected pile sections will bring the end surfaces of the concrete body of the pile into contact with each other.
