Definitions
- the invention relates to devices for anchoring stretched cables of generally cylindrical outline on solid masses, generally made of concrete, through which these cables pass.
- each section of cable 2 i --the index i designating the rank of the section or span considered-- must be tensioned after construction of the span 1 i which it crosses and which it is intended to reinforce, and this tension must be maintained using an anchoring device A bearing against this span and clamping the outgoing end of the section.
- the portion of the cable, which is then external to the portion of the built structure, is still relatively long and generally wound in a coil 3, so that its end is inaccessible.
- the anchoring devices according to the invention make it possible to obtain the result indicated above by their mounting "astride” on the sections of cable to be anchored.
- a frustoconical housing for a split frustoconical jaw suitable for surrounding and tightening a section of the cable to be anchored and they are essentially characterized by that they include a U-shaped body capable of overlapping said section, a body whose wings are extended by flanges directed towards one another, and a pin suitable for being housed in the U-shaped opening of said body to bear against the edges of its wings, the entire body and ankle being drawn so as to define the frustoconical housing.
- an anchoring device To implement such an anchoring device, it is placed around the section of cable exiting the structure, - that is to say in the immediate vicinity of this structure so as to bear axially against it -
- the desired anchoring is then carried out by tightening the jaw radially around the cable section by axial biasing of this jaw in the direction of the structure, the narrowed portion of said jaw being arranged axially on the side of this structure.
- a device comprising a U-shaped body suitable for overlapping a section of cable is known from DE-C-801 407. This document does not, however, provide for application to a cable with a generally cylindrical outline.
- the invention includes, apart from these main provisions, certain other provisions which are preferably used at the same time and which will be more explicitly discussed below.
- FIGS. 4 and 5 show respectively in end view and in axial section along V-V, Figure 4, an anchoring device established in accordance with the invention.
- this anchoring device is arranged so that it can be mounted astride a common portion of a prestressing cable, in order to surround and tighten this portion, which constitutes one end of a stretched section of said cable or is intended to later constitute such an end.
- the body 8 is extended by a transverse base 10 for pressure distribution split at the right of the opening of said body and it is reinforced by ribs 11 connecting the base to the body.
- two of the ribs 11 bear respectively on the roots of the flanges 9 so as to oppose their mutual spacing.
- the body 8 and the pin 12 are designed so as to define together a frustoconical internal housing 13 for a split frustoconical jaw 14, the small diameter end of this housing being located on the side of the base 10.
- the jaw 14 is composed in a manner known per se three identical keys together defining a cylindrical internal face suitable for contiguously surrounding the section of cable to be anchored.
- An anchoring device is then placed without its ankle straddling the portion of the section to be anchored, just protruding axially outside the sole 15, and the base 10 of this device is applied against this sole.
- this jaw 14 are chosen such that its large base projects axially out of said housing at the end of its introduction.
- a thrust device arranged so as to be able to overlap the strand, of the cable in question, leaving the structure.
- such a thrust device bears axially in two opposite directions respectively on the cable 2 and on the structure 1 armed by this cable, by means of the jaw 14 and of the body-ankle assembly 8-12, and said device comprises for example two parallel jacks arranged on either side of said cable, jacks joined together by split frames overlapping the cable.
- the pushing device bears in two opposite directions on the two faces in manhole, of the hopper, which are crossed by the tensioned cable to cut or more precisely on the jaws 14 of two anchoring devices mounted in the immediate vicinity of these two faces, and this device advantageously comprises a play of at least two corners able to slide transversely against each other and split so as to overlap the section 6, their mutual transverse movements being controlled by an appropriate jack.
- This device has a certain number of advantages compared to those previously known and in particular that of being able to be very easily mounted astride a section of cable to be anchored whose free end is not accessible for the threading of an annular piece.
- the proposed anchoring devices can be recovered as and when the advancement of the fact that successive tensioning of the contiguous strands 2 i of the cable 2 results in equalization of tensions on either side of the anchoring devices previously put in place, which makes it possible to loosen the jaws 14 correspondents: it is then enough to release these jaws axially, then the pin 12 - if, as it is supposed, the space available is sufficient for this purpose - to make possible the radial release of the body 8.
