STABILIZING RODS FOR STONE SLABS WITH A UNIDIRECTIONAL SCRIM

Abstract

Disclosed is a stone or ceramic plate stabilized with the aid of fiber-coated stabilizing strips, which are mounted below the edges of the stone slat or incorporated below the edges in the stone slat. The strips are characterized in that, for reasons of optimizing the material, they have an arrangement of the fiber direction at the top and bottom for the respective load case as a tension belt and are therefore designed with unidirectional fiber layers and these fibers are as close as possible to the respective surface of the top and bottom lie to be stabilized stone plate. The tension belt preferably has a height or thickness which is greater than half the thickness of the stone slab to be stabilized and a width which is appropriate to the total load at the respectively occurring bending load.

Claims

1) stone plate, artificial stone plate or ceramic plate stabilized by one or more strips of material at the edge or edges at the bottom of the plate, the stabilizing strip itself being made of stoneware, ceramic, glass, wood or other pressure-resistant material, which is coated on the top and bottom with fibers, characterized in that the fibers are aligned at the bottom of the strip mainly in the longitudinal direction.

2) Arrangement according to claim 1, characterized in that the fiber layers are arranged on the upper side of the strip mainly in the longitudinal direction.

3) Arrangement according to claim 1, characterized in that the fiber layers are arranged on the upper side of the strip mainly in the transverse direction.

4) Arrangement according to claim 1, characterized in that the fiber layers are arranged on the upper side of the strip in a layer exclusively in the transverse direction and are aligned in a further layer on the upper side exclusively in the longitudinal direction.

5) Arrangement according to claim 1, characterized in that the uppermost fiber layer is arranged on the upper side of the strip exclusively in the longitudinal direction as a layer.

6) Arrangement according to claim 1, characterized in that the fiber layers are applied under prestress to the strip of pressure-stable material.

7) Arrangement according to claim 1, characterized in that the fiber layer consists of carbon fibers, glass fibers or stone fibers or a mixture of these fibers.

8) Arrangement according to claim 1, characterized in that the coated strip in its core consists of natural stone, basalt, granite, marble, ceramic, glass ceramic, artificial stone, concrete, glass, other mineral materials or hardwood.

9) Arrangement according to claim 1, characterized in that the coefficient of expansion of an existing stoneware strip is as equal or identical as possible to be stabilized stone bar.

10) Arrangement according to claim 1, characterized in that the strip with a specially designed tensile stable top of the strip in the longitudinal direction is located, introduced or glued in a cutout below the plate as close to the surface of the stone plate to be stabilized.

11) Arrangement according to claim 1, characterized in that the strip specially designed to be tensile resistant in the longitudinal direction on the top of the strip is mounted, inserted or glued in a cutout below the plate so that the top of the strip is located above the center line of the stone plate to be stabilized.

Description

[0007] The invention is carried out as shown in FIG. 1, for example, so that a granite plate with a thickness of about 10 mm at the top (1) shows only stone and on the bottom (2) is equipped with carbon fiber-coated ceramic strips being glued into a cutout in the Stone slab. In FIG. 2, the cross section of the plate is shown, wherein the quasi-completely in the middle located ceramic strip (4) is coated on the top and bottom with a UD carbon fiber (3) in the longitudinal direction and on the top with a UD carbon fiber layer (5) in the transverse direction lying between the UD Longitudinal fiber and the ceramic strips.

[0008] The two UD longitudinal fiber layers protect the entire plate at the top and bottom against breakage at bending load in the longitudinal direction of the plate, wherein the UD fiber layer in the transverse direction prevents the breaking of the edge bending load by bending at the edge of the plate in the transverse direction, if the plate for example prodtrudes beyond the support of a kitchen cabinet body. Special stability is achieved when the carbon fiber is applied under prestress onto the ceramic strip.
