(262 Rutherford Blvd, Clifton, NJ. 07014) Filed Apr. 6, 1965, Ser. No. 446,034 1 Claim. (Cl. 61-53) ABSTRACT OF THE DISCLOSURE An H-beam pile section having an elongated H-shaped body with rectangular shaped web and flanges across the long edges of the web, the web and flanges defining channels on both sides of the web, the flanges being thickened at one end on the inner sides thereof with a series of thickened formations, the web being thickened at the same end and on both sides thereof with separate thickened formations, said formation being thickest at the outer one end and continuing into narrower formations, continuing inwardly into still narrower formations, and narrow slanting shoulders on the inner ends of said still narrower formations. A modification of the invention involves a joint between two pile sections, welded end to end, the adjacent ends having flanges with thickened formations, the web of one section adjacent the joint having thickened formations on both sides.
This invention relates generally to foundation piling and more particularly to an H-beam pile.
Strength at the point where the H-beam pile enters the soil and at the point where sections of a sectional H-beam pile are joined together is of critical importance.
It is therefore a primary object of the present invention to provide an H-beam pile wherein at one end the flanges and web have enlarged, reinforced and stepped upset ends.
Another object of-the invention is to provide an H- beam pile section wherein at one end the flanges and/ or web have enlarged, reinforced and stepped upset ends.
A further object of the invention is to provide a new method of reinforcing an H-beam pile by upsetting one end thereof.
Another object of the invention is to provide a joint for a sectional H-beam pile that possessesa maximum of vertical strength, together with a maximum of lateral strength and rigidity to withstand the excessive strain to which the pile sections are subjected to when the pile is being driven into the soil.
A further object of the invention according to a modification thereof is to provide a tip or point for an H-beam pile that provides a maximum of skin friction.
It is also an object according to another modification of the invention to provide an H-beam pile with a reinforced upset bottom end that reinforces the web and flanges of the pile and assures that the reinforced end is stronger than the remainder of the pile.
For further comprehension of the invention and of the objects and advantages thereof reference will be had to the following description and accompanying drawings and to the appended claim wherein the novel features of the invention are more particularly set forth.
In the accompanying drawings forming a material part of this disclosure:

FIG. 11 is a perspective view of a fragment of an H- beam pile showing a joint embodying the present invention made from the pilesections of FIGS. 1 and 3.
. FIG. 12 is a perspective view of an H-beam pile made in accordance with another modified form of the invention, parts being shown broken away.
FIG. 13 is a view similar to FIG. 1 of an H-beam pile embodying a further modified form of the invention.
With particular reference to FIGS. 1, 3, 6, 7, 9 and 10, herein H-beam pile sections are shown made in accordance with variou forms of the invention. Each section has an elongated H-shaped body with an elongated rectangular shaped web 16 and elongated rectangular shaped flanges 12 and 14 across the long edges of the web, extending the length thereof on both sides thereof. One end of the body of each pile section is upset by any suitable machine or method providing an enlarged, reinforced, stepped end portion 18 on the bottom of each flange 12 and 14 and a similar enlarged reinforced stepped portion 20 on the bottom end of the web 16 in the pile sections 10, 10" and 10a in FIGS. 1, 4 and 7, respectively, and on the top of each flange 12 and 14 and on the top of the web 16 in the sections 10", 10 and Mix in FIGS. 3, 6 and 9, respectively.
In pile sections 10 and 10a, in FIGS. 1 and 7, the reinforcedend portions 18 on the flanges 12 and 14 are on the outer surfaces of the flanges and on both opposed surfaces of the web. In section 10', FIG. 3, the reinforced end 18 is on the outer surface of the flanges 12 and 14 only. In sections 10" and 10", FIGS. 4 and 6, respectively, the reinforced ends 18 are on the inner surfaces of the flanges 12 and 14 and of the web 16. In pile sections 10a and 10x, FIGS. 7 and 9, the reinforced ends 18 are on both opposed surfaces of the flanges 12 and 14 and on both opposed surfaces of the web 16.
In FIG. 10, the bottom end of an H-beam pile 4i) embodying another form of the invention is shown. The pile is formed with an enlarged, reinforced, stepped bottom end 18a similar in construction to end 18 of pile section 10 of FIG. 1. The extreme bottom edges of the outermost thickened portions 22a are wedge-shaped as indicated at 34 on flanges 12a and 14a and as indicated at 36 on web 16a.
In FIG. 11, an example of a joint 42 made in accordance with the invention is shown composed of the pile sections 10 of FIG. 1 and 10' of FIG. 3. The joint is made by superimposing the pile section 1 0 on top of the pile section 10' and welding the abut-ting ends together as indicated at 44.
FIG. 12 illustrates an H-beam pile embodying another modified form of the invention. The pile 46 comprises opposed flanges 48, 48 connected by a web 50. The bottom end of the pile is constructed similarly to the bottom end 18 of pile section 10 of FIG. 1 and similar reference numerals are used to identify similar parts.
In FIG. 13, the bottom end of an H-beam pi'le is shown embodying a further modified form of the invention. The pile is formed with an enlarged, reinforced stepped bottom end somewhat similar to the 'bottom of the pile 40 of FIG. 10 but the flanges 52, 52 are provided with an 3 extension having tapering side edges 54 continuing into straight horizontal portion 56. Web 58 is similar to web 16a of H-beam 40 of FIG. 10.
The ends 18 of the pile sections and the end of the pile 46 may be upset according to conventional methods. Broadly the end is heated to forging temperatures. Then it is placed in a special die in the upsetting machine which hot forges the metal at the end to form a shoulder that results in a greater wall thickness in the area that has been upset. After cooling, the pile section or pile is placed on an automatic facing machine where it is faced. Of course the thickened and stepped ends 18 and end of pile 46 may be formed by casting or molding.
On the enlarged stepped ends 18 shown on the various forms of pile section and bottom end of pile 46, the extreme outer end portion 22 of each pile section and pile end is thickest with a flat surface 24. The outer portion 22 continues into a narrower adjacent portion 26 with an inwardly slanting outer surface 28. Portion 26 continues into a narrower straight flat portion 30 of the same thickness as the outer end of the portion 26 and is provided with a flat outer surface 32, continuing into an inwardly narrow tapering portion 34 merging with the bodies of the flanges and web.
The reinforced joints provide and the reinforced entrance tip or point of the pile give maximum strength thereby preventing buckling, bending or distortion of the flanges of the pile.
In using the pile 40 shown in FIG. 10, the bottom thickened stepped end 18a being wedge-shaped displaces the earth as it travels through the earth formations. The displaced earth tends to press back against the surfaces of the pile after the thickened bottom end 18a passes but since the upper end portion 30 of the thickened end is thicker in cross-section than the flanges 12a and 14a and web 16a, there is formed immediately above the thickened end 18a a pocket or cavity which extends completely around the adjacent lower portion of the pile. The displaced earth however immediately falls by gravity or is forced into contact with the surfaces of the pile as the pile is driven farther into the earth formation, thereby providing the necessary 'lateral support.
The thickened reinforced stepped bottom end of the pile 46 shown in FIG. 12 gives the pile the ability to force the ground apart when it is driven and so develop skin friction which gives it additional lateral supporting power. Piles like pile 46 are particularly adapted for use in bridge work where the piles must be driven into a rock bottom since their great strength and penetrating power permit them to enter the rock.
While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed but that changes in details of construction might be resorted to without departing from the principle of the invention and I desire therefore to be limited only by the state of the prior art and the appended claim.
