Description

Anchor element for cables

  The present invention relates to an anchoring element

  ge for cables, especially for tensioning cables or

  constraint, which comprises, on its side corresponding to the input-cable, means which serve to fix a tube, where appropriate, removably means side of the anchor member corresponding to the entry

  the side which, after installation, is turned towards the

tion itself.

  The cables that pass through the piercing of

  the anchoring element are often surrounded by a tube of

  swimming in plastic material, which must be connected in

  at the entrance of the anchoring element so that this cladding tube also fulfills its role and has its raison d'être at the end of said element The cladding tubes can, if necessary, be fixed directly on the anchoring element, but in previous constructions a connection has often been used up to now, which was, for example, fixed on

  a cylindrical extension of the anchoring element

  metal wires were used, for example, for

  fixation. The present invention aims to develop a construction that allows to fix on the element

  anchoring the tubes in an elastic but relatively

  Rigid construction, without additional fastening means.

  For this purpose, the anchoring element of the type previously

  described herein, according to the present invention, to the

  piercing of the anchoring element, an abutment

  sand, intended to cooperate with parts of the tube to be fixed,

  which are correspondingly shaped.

  The traversable abutment is preferably provided in the piercing itself of the anchoring element. In another solution, the traversable abutment is provided on the outside face of a cylindrical section of the anchoring element, this section being concentric to the drilling of

the anchor element.

  2 - In both cases, the limit stop is

  preferably in the form of a circumferential prominence

  continuous conferencing of the comb type, concentric by

  relative to the piercing of the anchoring element.

  Therefore, when a hollow or a continuous circumferential recess is formed in the outer or inner wall of the tube to be fixed, it can be fixed

  on the anchoring element in the manner of a

  snap, without the need for further action If necessary, this assembly may

  to be disconnected again without difficulty.

  The present invention will be better understood using

  of the detailed description of an embodiment taken

  as a non-limitative example and illustrated by the

  Figure 1 is a sectional view of the structure with an anchoring element according to the present invention, and Figure 2 is a view of an enlarged section.

  of the construction according to Figure 1.

  FIG. 1 represents an anchoring element 2 sealed

  to concrete in a structure 1, in which a tensioning or prestressing cable 4 is anchored with wedges

  3 At the end 5 of the anchoring element 2, which cor-

  responds to the cable entry, the end of a tube made of

  7 is fixed in the bore 6 of said anchoring element, and this with the aid of a stopper 8, which cooperates with a corresponding refcnnement formed in the

plastic tube 7.

  The plastic tube 7, which, in the example shown, is in the form of a connector, serves as a transition for the tight attachment of the plastic cladding tube 9 itself, which surrounds the tensioning cable 4 La junction between the connector 7 and the cladding tube 9 is, for example, made using a band

adhesive 10.

  It is obvious that the quick attachment of the tube 7 on

  the anchoring element 2 can be carried out without any means

additional link.

  FIG. 2 represents, on a larger scale, the actual fixing point of the tube 7 on the anchoring element 2. The main characteristic is the passable abutment 8 which fits or becomes embedded (when the material of the tube 7 is sufficiently cold deformable) in

  a corresponding recess in the tube 7.

  It is in principle also conceivable that the tube 7 can be fixed, by a similar closure device (not shown), on the outer face of a cylindrical extension of the anchoring element In this case, the stopper, which is advantageously carried out in the form of a continuous circumferential prominence of the comb type, is on the face or the outer wall of a

such cylindrical extension.

  Figure 2 indicates that the comb-like prominence 8 preferably has a chamfer (or entry)

  8 'relatively soft, which is intended to facilitate the in-

troduction of the tube 7.

  To allow exact positioning of the tube 7, it is expected that the front end of the latter will strike, in the example shown, an end stop

  8 "provided in the anchoring element.

  Thanks to this simple fixing of a cladding tube or a connection of such a tube, it is easy to ensure

  the seal between the structure 1 and the cable 4.
