Description

Wall lining with improved impact strength {WALL BACKING LINING WITH IMPROVED IMPACT STRENGTH}

The present invention relates to the lining of vertical walls in a building for the purpose of providing heat and acoustic insulation or a smooth uniform surface. The walls generally have a height between 2.40m and 3m to form the walls of the timber-skeleton house, which consist of concrete walls, concrete blocks, bricks or stones and vertically straight timber.

EP-A 718 451 A1 and EP-727-546 A1, in particular, provide threaded rods fixed to the wall for the system to be insulated, and mineral face blankets for connection or insertion between the threaded rods. It is then taught that it is held toward the wall by a metal compartment that is fixed to the threaded bolt by a tapping plate.

For example, these sheet metals include two oppositely opposed jaws that engage the return flange of the U-section every half turn.

This system allows the distance of sections already in place in the wall sac to be precisely adjusted.

French Patent Publication Nos. 2 822 179 and 2 852 989 describe an improvement of the above means in which the clamps for fixing and locking the U-section are mounted to rotate or clamped on a tapered plate.

It should be noted that all types of support other than those described above may be applied within the context of the present invention. In particular, but not by way of limitation, European Patent Publication No. 1 156 172 A1, French Patent Publication No. 2 785 312, International Patent Publication No. WO 03/08734, French Patent Publication No. 2 779 467 and No. 2 805 298 The support described in the above is mentioned.

The contours may be C-, I-, L-, U-, W- or Z-sections, depending on their shape, and may also be called furrings. If the contours are of metal type, the contours conform to the draft standard of British Patent 14 195. The contours are inserted above and below in a U-shaped section or bracket, which is also called a rail and is fixed to the floor and ceiling. The gypsum board is placed to bear against the band and the rail and fits into this band.

Bands are conventionally laid vertically, but very rarely (see the example "Avis Technique 9 / 03-759 du Center Scientifique et Technique duaBtiment [Technical Document 9 / 03-759 of the Scientific and Technical Building Center]"). Stripes can be found, in particular two of them for the aforementioned wall heights. The belts, which will be mounted vertically, are usually fixed to the wall at a point located at mid-height—again, for the front side that makes up the aforementioned wall height and standard plasterboard, which will be described in more detail below.

It is an object of the present invention to increase the ductile impact resistance of wall linings. This resistance is brought about by the occupant, either directly or through a deformable object, which simulates the type of system that constructs the front gypsum on a frame fixed to the wall, simulating the type of impact often encountered on the building's interior walls. It is evaluated by applying to all kinds of collisions. The term "impact resistance" is meant here to maintain the absence of deformation and indentation of the gypsum board, the complete consequences of the gypsum boards, and the integrity of the joints of the gypsum boards.

As a result, the subject of the present invention is a substantially vertical wall lining comprising thermal and / or acoustical insulation, a skeleton constituting vertically located sections uniformly spaced along the wall, and a front face fixed to the skeleton. The lining is characterized in that the sections are fixed to the wall, respectively, in relation to the reference height, at points where they are alternately moved up and down, in particular between the mid-height of the wall and 1.5m above the floor.

In relation to the points alternately moving up and down to secure the sections to the wall, the reference height is actually the impact height of the soft impact experiment. Thus, a significant improvement in the ductile impact resistance at this impact height is obtained with the advantages of the present invention. Now, standardized soft impact tests can define various impact heights at the above mentioned intervals; For example, standard NF EN 596 specifies an impact height of 1.5 m from the floor.

The sections that make up the framework are essentially rigid and consist of metal or plastic. If the sections are of metal type, the inertia efficiency is generally between 0.2 and 2 cm ⁴ . If the sections are made of different materials, the Young's modulus multiplied by the section's inertia is typically between 60 N.m 2 and 600 N.m 2.

The specific arrangement of the sections fixed at the points allows the lining to withstand greater impact.

Preferably, the front side consists of gypsum board, which is in particular of a type that meets the NF P72-301 or ISO 6308 standard. Thus, these gypsum boards have one of the heavyweights by applying a mixture of plaster and water between two heavy-duty papers, to which an adjuvant can be added, for example, forming agents, fibers, and the like. Flip the longitudinal edges and glue them to the other.

In particular, gypsum boards may be mentioned gypsum boards having a thickness of 12.5 mm, a weight per unit area of values between 8.5 and 12.5 kg / m 2, a width of 1.20 m and a length between 2.5 and 3 m.

According to one of the features of the invention:

The amount of offset is substantially the same for all sections, ie all fixed points are offset by the same amount, whether up or down relative to the reference height defined above; And

This offset amount is between 10 and 24% of the height of the wall, preferably between 13 and 21%.

In a preferred embodiment, the thermal and / or acoustic insulation is a mineral wool blanket, in particular a glass wool or a rock wool blanket, having a density value between 10 and 100 kg / m 3. These materials exhibit good thermal insulation and fire properties (non-combustible).

Advantageously, the front face constitutes a gypsum board whose transverse dimension is a multiple of the spacing between two adjacent sections. For example, in the case where the above-described gypsum board measured with a length of 2.60 m and a width of 1.20 m is used, two cases are expected. If the gypsum board is installed vertically, the spacing between two adjacent sections will be 0.60 m, 0.40 m or 1.20 m, in the order of decreasing preference, as appropriate, whereas when installed horizontally, the spacing is for example 1.30. m, 0.65m or 0.325m.

According to an advantageous implementation, the lining comprises means for detachably fixing the section to the wall at a distance adjustable distance, which enables this adjustment to be carried out starting from a position where the means are fixed to the wall and also to the section. do.

The invention will be illustrated by the following description of the attached FIG.

1 shows a wall lining 1 constituting a covering comprising a mineral face panel 2 covered with a front face 3 constituting a gypsum board of the specific type mentioned above.

The gypsum board front face 3 is fixed perpendicularly to the metal frame 4 fixed in place by a mounting / fixing system comprising a threaded rod 5 and a plate 6.

The wall 1 to be lined is formed from grout brick or concrete block 7. The framework consists of U-shaped sections 8 placed vertically between the bottom rail 9 and the top rail 10.

The section 8 is located at a distance away from the wall which substantially corresponds to the spacing e of 60 cm and the thickness of the insulation panel 2 used.

Holes 11 are drilled every 60 cm in the longitudinal direction of the wall, optionally at the seam 12 of the concrete block or brick, above and below 40 cm of the intermediate height (total height: 2.50 m). Of course, if necessary, the hole may be separated from the seam.

After the wall plug (not shown) is installed, the threaded rod 5 is screwed into the wall outlet. An insulating panel 2 made of mineral wool with a density between 10 and 100 kg / m 3 is installed on the threaded rod 5.

Then, the plate 6 is always screwed onto the threaded rod. The twisting operation takes place over several millimeters and allows the distance between the plate 6 and the wall 1 to be precisely adjusted.

The section 8 is then fitted well, followed by the gypsum board front 3. The plate is described in particular in EP 718 451, which entails two opposite radial jaws opposite, which protrude from the wall (1) and are engaged by the U-shaped section (8) by engagement under the two return flanges. It is possible to fix it. Thus, the plate 6 is fixed to the section 8 each time the plate is rotated 180 °-the plate is disengaged (with the longitudinally aligned jaws of the section) in the engaged position every quarter turn of the plate. Go to location.

When the section 8 is already in place, it is possible for the plate 6 to be screwed onto the threaded rod 5. The same is also true with the systems described in the aforementioned French patent publications 2 822 179 and 2 852 989. With this system, the section 8 is free to cut into the clamped clamps or to rotate in relation to the plate. The plate extending beyond the U-shaped section can then be screwed onto the threaded rod without removing the section from the clamp.

Wall linings are subjected to impact resistance testing in accordance with the NF P 08-301 standard, which is applied to large and flexible bodies. This is to apply the impact obtained by the spherical-conical bag weighing 50 kg, swinging towards the wall after the assembly of the lining is completed. Impact experiments were carried out in summary experiments with a height of 2.60 m and impact points at mid-height.

The physical characteristics of the impact (in Joules) are proportional to the height lifted from the starting position of the bag, and the impact on the gypsum board occurs when the cable on which the bag hangs is in the vertical position.

The lining resists shock measured at 120 Joules, corresponding to a bag being raised 24 cm high.

The varying lining from this embodiment due to the fact that the sections are fixed to each wall at the point located at the mid-height of the wall only withstands an impact of 80 joules (corresponding to the bag being raised to 16 cm high). When the bag is raised to a height of 24 cm, the integrity of the wall is maintained.

The present invention relates to the lining of vertical walls in a building for the purpose of providing heat and acoustic insulation or a smooth uniform surface. The walls generally have a height between 2.40 m and 3 m and constitute the walls of the timber-skeleton house, consisting of concrete walls, concrete blocks, bricks or stones, and vertically straight timber.
