Definitions

  • the invention relates to a ram pile or ram pile part with an end piece for the front connection, connection fittings for the mutual connection of successive ram pile parts optionally being integrated into the end piece.
  • end pieces for ram pile parts have become known.
  • these are cap-like covers which are closed over the entire area at the front end (e.g. FR-A 22 94 271).
  • end pieces of ram pile parts there is a not insignificant danger that the material will decompose due to special influences, this danger has to be considered in particular with end pieces made of steel or cast iron.
  • the load-bearing capacity of the end pieces is reduced by the influences, so that, after a corresponding period of time, the permanent load that is exerted on ramming piles makes settlement possible. Settlements are then possible until the concrete sections of the ram arrow parts are supported on one another.
  • the invention has for its object to provide an end piece for a ram pile or a ram pile part, with which these disadvantages can be avoided and by which it is ensured that a permanent support by the ram pile is guaranteed without subsequent settling even in the event of decomposition. Furthermore, the connection between the ram pile or ram pile part and the end pieces should just be able to withstand the great stress when driving in the ram pile part.
  • the end boundary of the end piece has a plurality of openings which expand conically in the direction of the outer surface of the end piece, so that when the end piece is used as intended, the concrete casting is flush with the material of the end piece and the end piece is held positively in the concrete casting is.
  • FIG. 1 shows an end piece in a view from below, partially cut away; 2 shows a section along the line I - I in Fig. 1. 3 shows a section along the line II-11 in FIG. 1.
  • the end piece 1 is provided for the end closure of the individual parts of a driven pile, such an end piece being connected, for example, via a threaded connection 2 to reinforcing elements 3 projecting into the concrete pile.
  • connecting fittings 4 can then be integrated into the end piece 1.
  • the ramming pile parts abutting one another at the end face are then firmly connected to one another via such connecting fittings and corresponding connecting bodies.
  • These connecting fittings and the connecting bodies can be designed in a variety of ways, it being irrelevant to the present invention which type of connection is used here.
  • the present invention is concerned with the special design of this end piece in cooperation with the front end of a ram pile part. It is about that frontal boundary 5 of the end piece 1 a plurality of openings 6, 7 are provided, which expand conically in the direction of the surface 8 of the end piece 1.
  • a large central opening 8 is expediently provided and a plurality of smaller openings 7 in succession at the edge region of the end piece 1.
  • the size and number of the openings depend on the structural requirements in order to give the end piece 1 sufficient strength.
  • a border web 9 leads backwards from the surface 8 of the end piece 1, the width B of this border web 9 being greater than the thickness D of the end boundary 5 of the end piece 1.
  • This border web is also arranged that the central opening 6 widens conically towards the surface 8.
  • This special construction ensures that a firm, intimate connection between the concrete and the end piece is created, which can withstand the blows when driving the ram pile without problems.
  • the concrete sections are supported directly on one another, so that signs of decomposition, e.g. Rusting through the end piece has no influence on the load-bearing capacity of the ram pile.
  • a preferably circumferentially closed web 10 can advantageously also be provided at the edge region, which web is directed backwards from the surface 8 of the end piece 1.
  • This web 10 is inclined towards the free edge thereof at an acute angle to the outside.
  • an obliquely sloping end wall 11 is provided which can exert pressure on the subsequent concrete (under load and also when the ram pile parts are driven in). There is always pressure towards the pile center through the sloping end wall 11, so that no concrete parts can break out, as is the case e.g. is the case with a flat end wall and with arrangement of stiffening ribs etc.
  • end pieces can of course not only be made from a cast iron, but can also consist of a cast of non-ferrous metals, plastic or the like.
  • a welded construction would also be conceivable, the conical enlargements possibly being achieved by countersinks.
  • the shapes of the openings shown in the drawing are not necessarily specified, but all possible geometrical figures can be used for these openings.
