Definitions

  • the invention relates to concrete piles and more particularly to cast concrete piles and to a joint construction between adjacent sections of a cast concrete pile.
  • Cast reinforced concrete piles are used in large numbers in the construction of bridges, buildings and other structures requiring a firm foundation since this type of piling can be driven directly with a hammer and without the use of special equipment such as a driving mandrel required for the driving of metal shells for forming castin-place concrete piles.
  • cast reinforced concrete piles are extemely heavy and if of great len th and made in one piece and then transported to the pile driving site, very heavy equipment must be used for transporting and handling the same. Also it is ditlicult to avoid damage to long, heavy cast concrete piles in transporting the same.
  • cast reinforced concrete piles normally are cast in sections and the sections spliced or otherwise secured together at the driving site either rior to driving or in case of necessity when the driven pile is not long enough, as each section is driven.
  • blows of the driving hammer In driving a pile, blows of the driving hammer must necessarily be ap lied to the pile at the upper end thereof and freoue-ntly the end portion of a cast concrete pile may chip or spall because of the impact of the hammer blows so as to dama e the ioint between sp iced se tions and to i terfere wi h the pro er transmission of dri i g blows from one end of the pile to the other.
  • This difficulty is more of a problem where a ioint is m e after a lower section has been dri en, but the same difficulties can occur even though a splice or ioint is made prior to driving because of the necessity of transmitting the driving blows throu h the joint.
  • Figure 1 is a diagrammatic view of a sectional pile incorpor ting the improved joint construction of the present invention.
  • Fi 2 is an enlarged fra mentary sectional view through the pi e ioint illustrated in Fig. 1.
  • a cast reinforced sectional co crete pile is generally indicated at 1 in Fig. 1 and includes a lower section 2 and an upper section 3.
  • the lower section 2 is illustrated as bein t pered and may have any desired usual or standard en th such as twenty feet for a pile section 16 inches in diameter at its u per end and 10 inches in diameter at its lower end.
  • the lower end of the pile section 2 may be formed as shown.
  • the upper pile section 3 which forms an extension for the l was tapered section 2 m y have any desired length consistent ith the pile re mirements and for instance may be a fifteen f ot cylindrical extension.
  • the pile 1 has been described as comprising t o sections. it is t be underst od t at the pile may comprise any number of sectio s d pendin upon the requirements f a p r icular foundati n: a d the sections may have other engths or di meters than those des ribed.
  • the secti n 3 might have a length of five, ten or twenty feet a d addi ional sections may be joined at the nnner end of ection 3.
  • E h of the pile sections 2 and 3 may be fabricated t tu r or tapered tub r sh e ith a tub r wall 4 of reinforced concre e of desired thic ess.
  • These sections may be poure in forms but prefer b are fabricated b spinnin E ch section is provided with the usual l ngitudi al steel reinforcin rods 5 formed as a cage in the usual manner with spiral wire wrapping 6, such assembled rod and wire wrapped reinforcing cages 56 being placed in the forms before the concrete is poured or in the spinning mold prior to introducing the concrete therein.
  • the resulting reinforced pile section may have prestressed reinforcing members therein in accordance with usual practice.
  • the longitudinal reinforcing rods 5 are bent outward at 7 at their end portions to direct the ends of the rods 5 toward the outer annular corner of the end of the section which is to be abutted against an adjacent end of another section to be joined thereto.
  • An annular band-like metal ring 8 is secured by welding at 9 to the outer bent ends 7 of rods 5 at the joint forming end of each pile section 2 and 3, as shown.
  • the outer surface of the ring 8 conforms in contour to the outer surface of the pile section to which it is secured.
  • a plate-like disc or lateral ring end plate 1%) is provided at the joint abutting end of each pile section 2 or 3, as
  • the plate 10 preferably having a central aperture 11 therein conforming in contour to the longitudinally extending hole through such pile section.
  • the plate 10 is welded at 12 to the bent ends 7 of the longitudinal reinforcing rods 5 and is welded annularly at 13 to the outer annular end of the adjacent metal ring 8.
  • the rings 8 and end plates it) are preferably formed of steel and are assembled with the reinforcing rod cages when the latter are placed in the forms or spinning molds so that after the concrete has set, the plate and ring assembly forms an integral part of the resulting pile section with the plate 12 and ring 8 forming an annular angular covering and protecting device for the concrete at the end portion of the pile section.
  • pile sections when the pile sections are fabricated in the manner described, such sections may be transported to or assembled at a driving site in lengths or weights which are convenient to handle and a joint may be formed between the pile sections such as sections 2 and 3 by merely abutting the ends of said sections together, as illustrated in Fig. 2 and holding the same in abutted relation while the annular peripheral edges of the abutted plates 16 are welded together as indicated at 14.
  • the joint illustrated may be formed either prior to driving the joined sections or after one of the sections has been driven, since the improved plate and ring construction at the end of the driven pile section which is to be joined to another section, protects the concrete end of such section against spalling or cracking from the impact of the driving blows imparted by the pile driving hammer.
  • the plates 10 have been described as being annularly welded to each other to form the joint because it is believed that such welding forms the strongest and most efficient joint possible, it is understood that the present invention contemplates any means of rigidly securing the two plates 19 together at the joint.
  • the present invention provides a new, strong and efficient joint for permanently securing together sections of cast reinforced concrete piles which may be driven directly into the ground without the use of a mandrel; provides a cast concrete pile joint which enables the sections to be joined at the driving site usually prior to driving, but in case of necessity after a lower section has already been driven; provides a cast concrete pile joint construction in which the driving force is carried from end to end of a sectional pile through the reinforcing means in each section and the metal plates and rings at the ends of the section secured to the reinforcing means;
  • a first annular band-like metal ring secured to and surrounding the longitudinal pile reinforcing rods at an end portion of a first pile section, the outer surface of said ring conforming to the contour of the outer surface of said end portion of said first pile section, said first ring extending longitudinally from the end of said first pile section, a second annular band-like metal ring secured to and surrounding the longitudinal pile reinforcing rods at an end portion of a second pile section abutting the said first pile section, the outer surface of said second ring conforming to the contour of the outer surface of said end portion of said second pile section, said second ring extending longitudinally from the end of said second pile section, a first lateral metal end plate ring at the end of said first pile section joined to said first annular ring and the reinforcing rods secured thereto, a second lateral metal end plate ring at the end of said second pile section joined
  • a plurality of end-abutted cast concrete pile sections each having longitudinal reinforcing rods therein, a joint between end-abutted pile sections including a cylindrical metal ring adjacent each section end to be joined to another section end, a lateral metal end plate at each section end to be joined integrally secured to said metal ring, each said ring and plate being integrally secured to the longitudinal reinforcing rods in each section, the plates of end-abutted pile sections being abutted to form a joint therebetween, and means integrally securing said plates together.
  • each pile section includes cast tubular concrete walls having metal reinforcing rods extending longitudinally of the tubular walls, in which said rods are bent outwardly toward the outer annular corner of the joint forming pile section end, and in which the lateral plates are washerlike in shape and are welded to the cylindrical rings, the bent reinforcing rod ends, and to each other to integrally secure the pile sections together.
