Description

The present invention relates to an insulating lining panel for the building industry.

The invention finds a particularly advantageous application in the field of the building industry, in particular for the realization of dubbing new premises or renovation of old premises.

In order to mount louvers intended to be applied against a wall presenting flatness defects and / or surface irregularities, a technique known to the building industry, consisting in assembling plates of a building material, is used. such as plaster tiles masonry like bricks, or plasterboard.

However, plaster tiles have the disadvantage of being heavy and expensive masonry labor, while, moreover, the realization of drywall requires the installation of a complex skeleton climbing from the floor to the ceiling of the room in question. In addition, because of the poor performance of the plaster, the partitions thus obtained do not offer satisfactory qualities as to the mechanical strength and thermal insulation.

To overcome these drawbacks, it has already been proposed panels for doubling an interior wall, a partition or a roof of a construction, of the type consisting of an insulating material and an associated finishing plate.

However, a difficulty remains in the distribution mode of electric cables, or hydraulic pipes or ventilation ducts, when it is desired that they be recessed.

It is not thinkable to make bleeds in the finishing plate, usually in plaster, and in the insulation on which it is fixed, because not only it would be necessary to reseal them after passage of the cables or pipes, but it would create as many thermal bridges as there are bleeds, which would be detrimental to good insulation according to the desired purpose.

Also, known panels of the aforementioned type have opposite edges recessed over the entire height, allowing their assembly contiguous edges with a successive panel.

This presents a second difficulty which lies in the alignment of the panels between them during their presentation on the wall to be doubled.

The prior art described in the German documents DE29924488U which describes a doubling panel according to the preamble of claim 1 and US US 5,930,960 if it solves the first problem stated, does not solve the second problem.

In addition, if these documents describe panels with horizontal and vertical internal grooves, these are made on both sides of faces of the panel, which has the disadvantage of reducing the insulating mass on its so-called hot face, but also on its so-called cold side, that is to say external wall side to be insulated, which reduces the technical characteristics of the panel .

According to this first phase of the inventive step, it has therefore been sought to produce a panel whose all the vertical and horizontal grooves are located behind the hot face exclusively, and this by making them cross, which also authorizes an easier realization of two horizontal and vertical circuits in the same room and the replacement or the addition of electrical accessories for example, on demand, without damaging the support or its finish.

The object of the invention is to solve all of these drawbacks and concerns for this purpose a panel according to claim 1 for doubling an interior wall, a partition or a roof of a construction, of the type constituted by by an insulating material and an associated finishing plate, said panel having opposing edges recessed over the entire height, allowing its assembly with contiguous edges with a successive panel, and at least one horizontal internal groove, preconceived, passing right through its insulating part, intersecting with at least one vertical vertical groove, preconceived, said grooves being made in the insulating part, immediately behind the finishing plate, the vertical groove being deeper than the horizontal grooves.

Thus the installation of panels is greatly simplified, both for the building professional than for the electrician or the heating engineer who will find a network of pre-established grooves inside the panels themselves and usable on demand according to the configuration of the installation to realize.

The present invention also relates to the features which will emerge during the following description, which should be considered individually or in all their possible technical combinations within the limits defined by the claims.

According to the invention, the panel 1 comprises at least one horizontal internal groove 6, preconceived, passing right through its insulating part 2 and adapted to receive, by one of its ends, a chute 7, partially embedded in the groove 6 and for part 7c, 7d protruding, to cooperate with the corresponding groove 6 of a successive panel 1A, 1B, so as to allow the passage of hydraulic pipes or electrical cables, while ensuring the self-alignment of said groove 6 during assembly of the panels.

More specifically, the groove 6 is made in the insulating part 2, immediately behind the finishing plate 3, and whose hollow section is of semicircular shape extending with straight portions 6a, 6b, so as to allow the introduction the self-aligning chute 7 of corresponding U-shape 7a, 7b, while preventing its rotation.

According to an alternative embodiment, the groove 6 is made in the insulating part 2, immediately behind the finishing plate 3, and whose hollow section is U-shaped at right angles, so as to allow the introduction of the chute 7 correspondingly shaped U, while preventing its rotation.

According to another variant, the groove 6 is made in the insulating part 2, immediately behind the finishing plate 3, and whose hollow section is V-shaped, so as to allow the introduction of the trough 7 of corresponding shape by V, while preventing its rotation.

Preferably, the end edges 7c, 7d of the self-aligning chute 7 are rounded, to facilitate its insertion on either side of the grooves 6 of two successive panels 1A, 1B.

According to an alternative embodiment, represented on the Figures 4, 5, 6 , the chute 7A is intended for the self-alignment of two successive panels forming an incoming or outgoing angle and comprises, in its central part, on either side of its lateral sides 7a, 7b vis-à-vis, two V-notches 7f, 7g-7h, 7i, with a predetermined identical angle α, allowing the request to be folded in one direction or the other, around a fictitious line 7j joining the two points of the V of the cuts 7f , 7g-7h, 7i, to obtain a chute 7 ', 7 ", angle reentrant or outgoing.

Also the rounded back 7e or one of the sides of the self-aligning chute 7 is bristle outwardly of a lug 8 forming a stop against the insulating portion 2 of one of the panels 1,1A, 1B, at the moment of its introduction into its groove 6.

The chute 7 is made of galvanized steel, but of course, it could be in any other material, such as plastic.

According to a practical example of embodiment, the grooves 6, and consequently the chutes 7, have a U-section of: h = 30 mm, l = 30 mm, for L = 100 mm.

The horizontal grooves 6 are crossed with at least one vertical groove 9.

The latter 9, unlike the other horizontal 6, has a section of: h = 50 mm, l = 30 mm. This therefore allows grooving of constant width.
