Description

Title of the invention: REINFORCED SELF-ADHESIVE SEALING TAPE Technical field

[0001] The present invention relates to the field of building equipment.

[0002] The present invention relates more particularly to a self-adhesive strip used for waterproof protection of corners in humid environments. Prior art

[0003] The implementation of a sealing strip in an Italian-style shower on an upper floor is mandatory, in accordance with the NF DTU 52-2 PI-1-1 & 3 standard as well as the CSTB 3567 specification in order to create the junction between the floor and the wall (peripheral upstand). The APSEL professional rules supplement these standards.

[0004] Currently, the implementation of a sealing strip is quite complex and time-consuming. Indeed, it is necessary to first apply a liquid sealing product with a brush and a roller in all the angles exposed to water. Then, it is necessary to smooth the strip into the fresh product using a trowel and a painter's spatula, taking care to cut it to the correct length beforehand. Operators must wear gloves because the product is very sticky and messy.

[0005] The strip is placed in the corner trying to follow the central edge to form an “L” or right angle.

[0006] There are also self-adhesive strips on the market, but they do not have the internal reinforcement that allows for pre-forming an angle. Their installation is tricky because these strips have no structural support: in fact, they fold back on themselves.

[0007] The difficulty is to position the lower part (floor) and the upper part (wall) equally. It very often happens that the strip is positioned at an angle and does not cover the entire length. In this case, it becomes useless.

[0008] As a result, the application time is long: approximately twenty minutes for an experienced craftsman and thirty minutes for a beginner to complete the interior of a shower.

[0009] The other solutions known from the state of the art are as follows: - Do not apply tape in the corners and apply more sealant. There is a saving on material costs and on installation time, but if there is an expert appraisal following a disaster, all the faults will be borne by the tiler. - Apply adhesive tape but not reinforced. The implementation is complex because the strip folds back on itself, and it is laborious to stick it properly in the corners. - Glue silicone strips over the tiles in the corners. This is more expensive and also less aesthetically pleasing. Statement of the invention

[0010] The invention aims to remedy the drawbacks of the prior art by proposing a self-adhesive strip serving as waterproof protection for corners in humid environments.

[0011] For this purpose, the invention relates to a self-adhesive strip, comprising a self-adhesive face, a mechanical reinforcement providing rigidity at the central fold, a waterproof film and a woven textile.

[0012] According to one embodiment, the mechanical reinforcement consists of a fiberglass and butyl glue frame. Brief description of the drawings

[0017] The present invention relates to a self-adhesive strip 100.

[0018] The strip 100 according to the present invention comprises a self-adhesive face 110, a mechanical reinforcement 120 providing rigidity at the central fold, a waterproof film 130 and a woven textile 140.

[0019] [Fig.l] illustrates the self-adhesive strip 100 according to the invention, in one embodiment.

[0020] [Fig.l] shows the self-adhesive strip 100 according to the present invention, which comprises a self-adhesive face 110, a mechanical reinforcement 120 providing rigidity at the central fold, a waterproof film 130 and a woven textile 140.

[0021] [Fig.2] is a partial view of the self-adhesive strip according to the invention, in one embodiment.

[0022] Also observed in [Fig.2] is the self-adhesive face 110, the mechanical reinforcement 120 providing rigidity at the central fold, the waterproof film 130 and the woven textile 140.

[0023] [Fig. 3] illustrates the self-adhesive strip 100 according to the invention, in one embodiment lization.

[0024] [Fig.4] is a partial view of the self-adhesive strip according to the invention, in one embodiment.

[0025] Also observed in [Fig.4] is the self-adhesive face 110, the mechanical reinforcement 120 providing rigidity at the central fold, the waterproof film 130 and the woven textile 140.

[0026] In one embodiment, the mechanical reinforcement 120 is made up of a fiberglass and butyl glue frame.

[0027] The woven textile 140 allows the attachment of coatings such as liquid waterproofing, tile adhesive, leveling compound, resin, or waxed concrete.

[0028] The strip 100 according to the present invention can be implemented without adding glue to its underside, therefore it adheres to different materials: concrete, plasterboard, waterproofing coating, cement mortars, paint, old tiles, wooden panels; in new or renovated buildings.

[0029] The strip 100 according to the present invention ensures the sealing of the incoming and outgoing angles in showers, toilets, swimming pools, spas, hammams, basins, reservoirs, cellars, terraces, balconies, roof terraces.

[0030] Implementation does not require applying a product beforehand. First, the strip is cut to the correct length using scissors. Then the strip is pre-formed by folding it back on itself from one edge to the other, to form an angle. Its structural reinforcement allows for a perfectly right angle. Next, the protective film is removed from the self-adhesive strip on one side; then this side of the strip is placed along the linearity of the angle (on the floor or wall). Rub it with your hand to make the glue adhere, then the other protective film is removed from the opposite side and placed on the support. This gives a strip forming a right angle in the angle, with strong adhesion and perfectly aligned with the linearity, and all this in a short time (two minutes).

[0031] The product according to the present invention makes it possible to carry out a complete shower in seven minutes.

[0032] The advantages of the product according to the present invention are as follows: - Easy to install in all configurations - Ideal for sealing a wall niche - Quick to set up - Particularly effective - Multi-supports - Can be installed by a person who is not particularly qualified (does not require any special skills) - Few tools to use Clean site (dry product) Made with 30% recycled material.
