Definitions
- the invention relates to a method for strengthening the holding of an anchoring element. drowned in a concrete slab.
- the method according to the invention is used in particular for improve the strength of the anchoring elements for fixing the saddles supporting the rails of a railway track resting on a concrete slab.
- Document FR 2 425 014 discloses anchoring elements which are directly embedded in a concrete slab which allows the fixing of a railroad track, these anchoring elements consisting of an anchoring sheath having an envelope external metal provided with multiple beads coming into contact with concrete and a a lag screw screwing into the anchor sheath.
- Such anchors are usually embedded in the slab while sinking simply, by gravity, concrete around the anchor.
- it is often difficult to obtain good contact between the concrete and the anchor element because for example the formation of air bubbles at the interface between the anchoring element and the concrete, or when the surface condition of the anchor element does not allow a good natural bonding of concrete, or even when a phenomenon of repulsion due to the texture and nature of the materials in contact like this this is particularly the case when the anchoring element is galvanized and passivated, which limits the holding of the anchoring element in the concrete slab.
- an object of the present invention is to provide a method for strengthening the holding an anchor in a concrete slab that is simple and economical to achieve.
- the invention relates to a method for reinforcing the holding of an element anchor embedded in a concrete slab, characterized in that, prior to the pouring the concrete slab around the anchor element, coating the element for anchoring a mortar made of a resin mixed with sand and cement.
- the resin is an ethylene polymer acetate vinyl.
- the anchoring element is consisting of an anchoring sheath receiving a lag screw and comprising an envelope galvanized metal exterior.
- the anchoring element is used for fixing a railway track.
- FIG. 1 represents an anchoring element embedded in a concrete slab 2 according to a particular embodiment of the method according to the invention.
- the anchoring element 1 comprises an anchoring sheath 11, known per se, into which a lag screw 12 is screwed, this lag screw 12 serving to immobilize the base 5 of a saddle intended to support a non-railway track shown in the figure.
- the anchoring sheath 11 has an outer casing galvanized and passivated metal.
- the envelope of the anchoring sheath 11 is covered, prior to pouring the concrete slab 2, a mortar 3 made of a resin mixed with sand and cement.
- the resin used is preferably a ethylene vinyl acetate polymer.
- This mortar 3 is advantageously applied to the anchoring sheaths 11 in a independent operation carried out well before pouring the concrete slab 2 so that mortar 3 is perfectly dry when handling the anchor sheaths 11 and when pouring the concrete slab 2.
- the concrete slab 2 is for example obtained by simple gravity casting in a formwork, the concrete flowing around the mortar 3 covering the anchoring sheath 11, the latter being maintained in a fixed position during this operation.
- Such a method makes it possible to significantly improve the behavior of the anchoring sheath in the concrete slab thanks to the very good cohesion between the metal casing galvanized anchor sheath and mortar as well as between mortar and concrete.
- the invention also applies to other types of anchoring elements and may in particular be used to strengthen the holding of an anchor rod substantially smooth intended to be embedded directly in a concrete slab and having a threaded upper part, projecting from the concrete slab, intended for receive fasteners from the railway and allow their immobilization at by means of a nut.
