Definitions

  • This invention relates to load-bearing piles, and in particular end caps for such piles which secure a structure upon the pile.
  • Steel piles are used in various construction applications to carry vertical loads.
  • One example of such an application is in railway engineering.
  • railway engineers utilise mild steel tubular sections as piles to support track-side structures such as gantries supporting electrical cables or signalling apparatus.
  • the piles supplied to the railway engineers are pre-cut to designated lengths, and are prepared with prefabricated connectors which connect a support member of the rail-side structure to the pile. If a pile cannot be driven into the ground to the required level then these prefabricated connectors cannot be used in their original form. This requires extensive remedial works to be carried out on site, which increases the time and cost of the engineering work.
  • brackets, site cutting and drilling There have been attempts to overcome this problem using brackets, site cutting and drilling. However, each of these attempts to solve the problem is very expensive and time consuming.
  • an end cap for securing a structure upon a pile comprising:
  • the body may further comprise at least one positioning aperture, wherein the at least one positioning aperture in use receives at least one positioning fixture to position the end cap on the pile.
  • the end cap may further comprise at least one structure fixture extending through a corresponding at least one of the structure fixing apertures, and a transportation member attached to the at least one structure fixture for transportation of the end cap.
  • the body may comprise a plurality of body portions, wherein each body portion comprises at least one pile fixing aperture.
  • Each body portion may further comprise at least one positioning aperture, wherein the at least one positioning aperture in use receives at least one positioning fixture to position the end cap on the pile.
  • the end cap may further comprise at least one structure fixture extending through a corresponding at least one of the structure fixing apertures, and a transportation member attached to the at least one structure fixture for transportation of the end cap.
  • the plurality of structure fixing apertures may be equidistantly spaced about the at least one attachment flange.
  • a foundation for a structure comprising a pile, and an end cap according to the first aspect of the invention.
  • a method of securing a structure upon a pile using an end cap comprising:
  • the body may further comprise at least one positioning aperture and prior to securing the cap to the pile the end cap is positioned on the pile by threading at least one positioning fixture through the at least one positioning aperture to engage the pile.
  • the end cap 10 comprises a tubular body 12 and an annular attachment flange 14 which is attached to an upper end of the body 12.
  • the body 12 is adapted to fit over an end of a tubular steel pile 16.
  • the body 12 is sized so that there is a close fit between an internal surface of the body and an outer surface of the pile 16.
  • the body 12 includes a plurality of fixing apertures 18 which in use will receive a pile fixture 30 which secures the cap 10 to the pile 16.
  • the pile fixing apertures 18 may be arranged circumferentially about the body 12.
  • the body 12 includes a plurality of optional body portions or tabs 20.
  • Each body portion 20 has a pair of pile fixing apertures 18.
  • the body 12 may have a plurality of positioning apertures 22, or each body portion 20 may have at least one positioning aperture.
  • the positioning apertures 22 in use receive a positioning fixture such as a grub screw which secures the end cap 10 in position and in the correct orientation on the pile 16 while apertures are formed in the pile 16.
  • the attachment flange 14 includes a plurality of structure fixing apertures 24.
  • the structure fixing apertures 24 each receive a structure fixture 28 which secures a structure to the cap 10, as will be described in more detail below.
  • there is a single attachment flange 14 which is a continuous ring, and the plurality of structure fixing apertures 24 are equidistantly spaced around the attachment flange.
  • An upper face of the attachment flange 14 is preferably substantially perpendicular to a longitudinal axis of the cap body 12.
  • the body portion 12 and at least one attachment flange 14 may be integrally formed, or formed as separate members which are attached together to form an end cap 10.
  • the end cap 10 may be formed from steel.
  • the end cap 10 may optionally include a transportation member 26.
  • the transportation member 26 is fixed to the end cap 10 by a pair of the structure fixtures 28.
  • the structure fixtures 28 extend through the corresponding structure fixing apertures 24.
  • the transportation member 26 allows the end cap to be carried by installers to the site of installation, and is removed before a support member 32 of the structure is secured to the attachment flange 14.
  • Known mechanical fixtures such as nuts and bolts are suitable for securing the pile 16 to the end cap 10 and the end cap to the support member 32.
  • threaded screws may be used.
  • the end cap 10 is carried to the location of the pile 16. This may be achieved without the need for lifting machinery by two installers using the transportation member 26 to carry the end cap 10. Once at the location, the end cap 10 is placed over a protruding end of the pile 16, and the transportation member 26 is removed, if present. The rotational position of the end cap 10 on the pile 16 can be adjusted at this point so that the support member(s) 32 of the structure will be correctly oriented for securing to the end cap 10.
  • the installer then threads a positioning fixture (not shown) through each positioning aperture and into the outer surface of the pile 16. This temporarily holds the end cap 10 in position on the pile 16 whilst the final connections are made between the pile, end cap and structure.
  • the installer then drills holes in the pile 16 through the pile fixing apertures 18 in the body portions 20. Once the apertures in the pile 16 have been drilled, the installer then threads a pile fixture 30 through each pile fixing aperture 18 and its corresponding hole in the pile. This secures the cap 10 to the pile 16.
  • the structure to be supported is then brought into position on the upper surface of the attachment flange 14, and orientated such that apertures in a bottom surface of the support member are aligned with the corresponding structure fixing apertures 24 in the attachment flange 14.
  • the installer then threads a structure fixture 28 through each pair of aligned apertures and tightens a nut on the fixture to secure each support member 32 to the end cap 10 and the pile 16.
  • the end cap 10 described herein can be used to construct a foundation member 34 for a support member of a structure by placing it on an end of a pile 16.
  • the end cap may include a transportation member which is removed before the structure is fixed to the end cap, the end cap may be transported manually to the onsite location of the pile. This reduces the cost of the engineering work.
  • each body portion may include a positioning aperture
  • the end cap may be securely held to the end cap while the pile apertures are being drilled.
  • the body may not be a single cylindrical element which in use extends around the outer circumference of the pile. There may be a number of body portions that in use are spaced apart circumferentially and connected to one another by the attachment flange.
  • the end cap may comprise more than one attachment flange.
  • the attachment flanges may be spaced apart around the outer circumferential surface of the pile and extend from the body.
  • Each attachment flange may have a structure fixing aperture which in use receives a fixture to secure the attachment flange to the support member of the structure.
  • the at least one attachment flange may be a single steel plate.
  • the steel plate may include a centrally located structure aperture that can receive a structure fixture which can be used to secure the transportation member to the end cap.
  • the pile depicted in the drawings is tubular with a circular cross-section, and the end cap has been formed such that it can fit over it, but the end cap may be formed to fit over any cross-sectional shape of pile.
  • end cap described herein has been described in the context of piles used in rail-side construction. However, it should be understood that the end cap described herein can be used in conjunction with piles across all areas of construction.
