Definitions

  • the present invention consists of a coupling head for premanufactured prestressed piles whose purpose is to reinforce to a large degree the fastening of the head to each one of the ends of the prestressed piles so that when two consecutive piles are connected by the coupling heads of the invention, wear is avoided in the end areas of the piles when the piles are handled moments before being driven or sunk into the ground. Wear is also avoided when driving the piles into the ground, because in all cases, bending and shearing stresses are produced which above all affect the connecting area, as well as the future usefulness thereof since the connecting element is more resistant that the pile itself.
  • piles There is a limitation in the manufacturing of piles as far as their individual length is concerned, and therefore, sometimes it is necessary to connect several sections of piles at their ends (normally two) in order to attain the required depth driven down in order to normally find firm ground.
  • piles include in their ends some coupling heads in order to make connecting easier and also to reinforce these areas for the purpose of guaranteeing the sureness of the coupling above all during the handling of the piles when they are handled before and when they are driven into the ground. This is because bending stresses that have a negative effect on the piles are produced above all on the end sections of the piles where the coupling is done.
  • the invention proposes a coupling head for premanufactured prestressed piles that is essentially characterized in that the ends of the prestressed cables that the pilots include therein are integrally connected to the head itself either by welding, screwing or any other system.
  • the head comprises a front plate and two side plates welded together, which form a recess that surrounds the final ends of the pile.
  • This head includes inside it in turn solid bodies, as well as short cylindrical extensions that emerge frontally outward with respect to the front place. There are also holes made in this plate which are also made in the solid bodies, in such a way that when two piles are coupled, in a first step the cylindrical extensions of a pile are inserted into the front holes of the other continuous piles. Then the respective front plates of the two piles come into contact. In a second step to ensure the fastening between both piles, some shanks are inserted through some holes that originate in the side plates and that are also made in the solid bodies.
  • the cylindrical extensions also have holes and these extensions aside from being fastened to the front plates, are connected to some rods embedded in the concrete material of the pile.
  • the solid bodies are also connected to similar rods also embedded in the concrete material of the pile itself.
  • the front plates of the heads have some holes where some ends of the prestressed cables are inserted so that these cables are later made integral to the plates.
  • the solid bodies as well as the cylindrical extensions are connected by the rods by means of a fixed connection which may done by welding, screwing or another system.
  • the coupling head for premanufactured prestressed piles is defined by a front plate (1) and side plates (2) all of which are connected, at the same time that they form a recess that surrounds each end section of the respective pile (3).
  • the heads include inside them some solid bodies (4) connected integrally to the plates, as well as some cylindrical heads (5) that project beyond the front plates (1). There are also front holes (6) in the plate (1) that are also made in the solid bodies (4). The cylindrical heads (5) are also fastened to the front plates (1) of the respective heads.
  • the diametric holes (9) of the cylindrical heads (5) and the holes (8) of the side plates (2) and solid bodies (4) are a little off-center; all so that when the shanks (7) are inserted there is a firmer and more secure connection.
  • the solid bodies (4) as well as the cylindrical heads (5) are connected by fastening (10) to some rods (11) embedded in the concrete material of the piles (3).
  • the prestressed cables (12) of the piles (3) are connected integrally to the front plates (1).
  • the front plates (1) have small holes (13) where the ends of said prestressed cables (12) have been inserted in order to afterwards ensure their connection, even when stress has not been eliminated from the cables (12), but after the concrete material has set and dried.
  • connection of the front plate (1) to the prestressed tie-rods or cables (12) that constitute a very important technical advantage because in this way the connecting area of the piles (3) support great bending and shearing stresses, which are mainly produced during the handling of the piles (3) and when they are driven or sunk into the ground.
