Abstract

A reinforcing/strengthening element has an inner core (20 enclosed in a encapsulation (3), and is shaped for inserting into a recess (lengthwise groove) of a building material to be strengthened, and the encapsulation (3) has a molded outer contour for receiving an adhesive. An independent claim is given for a flat building material.

Description

The The invention relates to a reinforcing element according to the preamble of claim 1 and a plate-shaped building material according to claim 8.

Out the prior art is known, made of plastic frame profiles, for example Windows or doors made of plastic, with reinforcing elements to provide stability the thin one Profiles reinforce existing windows and doors. For this stable inner cores are cast in parts of these frame profiles.

An example of such generic reinforcing elements shows the DE 199 16 135 C1 , Therein, a reinforcing element for hollow sections made of plastic hollow profiles having an open, substantially U-shaped cross section is disclosed, wherein the reinforcing element is made there of a fiber composite material. In one of the plurality of legs of different thickness of the reinforcing element, a steel insert is inserted in order to give this so-called support leg greater stability. At the same time, this should ensure an improved K value in order to avoid the least possible heat loss through the frame.

at such lightweight construction materials or components is the manufacture the already provided with a stable inner core reinforcing element readily possible. Opposite exist in plate-shaped Building materials, especially stone slabs, very different Requirements for such reinforcing elements. For example, in the field of manufacturing countertops made of stone or other heavy, inherently stable materials (granite, Marble etc.) usually no reinforcing elements needed. Become in the worktops but recesses, for example for sink inserts or Cut hotplates, so usually remain only relatively narrow webs in the areas of the recess, in particular easy to break during transport due to the low elasticity of the materials can.

task Therefore, it is the object of the present invention to provide a reinforcing element for such disc-shaped To provide building materials that increases their stability and a enable safe transport.

These Task is by a reinforcing element with the features of claim 1 and a plate-shaped building material solved according to claim 8. Advantageous embodiments and expedient developments of the invention are in the subclaims specified.

The initially mentioned reinforcing element is characterized in that it is for insertion into a recess a building material to be reinforced is shaped and the sheath one for receiving an adhesive shaped outer contour having. By such reinforcing elements in particular narrow webs of building materials are reinforced. In addition, that can reinforcing element Manufacturing technology simply used in the building material and with glued to this.

In advantageous embodiments of the invention has the outer contour at least one longitudinal groove for receiving the adhesive or is grooved or roughened, so that the adhesive can adhere very well to the reinforcing element. Will be the inner core of the reinforcing element formed by a steel band, so can cost-effective manner a good reinforcement with simultaneous elasticity be achieved. Is the sheath made of a composite material, in particular a glass fiber reinforced plastic material, so let yourself This makes a particularly good connection of the reinforcing element to provide the building material.

Further Special features and advantages The invention will become apparent from the following description of preferred embodiments based on the drawings. Show it:

1 : A cross section through a first embodiment of a reinforcing element according to the invention;

2 : A cross section through a second embodiment of a reinforcing element according to the invention.

An in 1 illustrated band-shaped reinforcing element 1 has an inner core of a steel band 2 on, which has a substantially longitudinally rectangular cross-section. This inner core 2 is in a sheath 3 embedded in a glass fiber reinforced plastic, many times the thickness of the steel strip 2 thick and surrounds the steel strip from all sides.

The reinforcing element 1 is easy to manufacture and can be used simply in a correspondingly milled into a kitchen worktop of stone longitudinal groove due to its cross-sectional shape. To ensure the best possible connection with the flagstone, are side surfaces 4 . 5 the outer contour of the substantially rectangular sheath 3 roughened.

This in 2 illustrated embodiment of the reinforcing element 1 is different from the one in 1 shown essentially by the outer contour of the casing 3 , Therefore, the same parts will be given the same reference numerals and only the differences will be described.

The side surface 4 and the side surface 5 the sheath 3 point each other point-symmetrical to the center of the reinforcing element 1 oppositely disposed longitudinal grooves 6 . 7 on, which serve to receive adhesive. Will the reinforcing element 1 inserted into the corresponding groove of a web-shaped part of a countertop and glued therein, so put the components of the adhesive into the grooves 6 . 7 engage, after curing a particularly good connection and protection of the reinforcing element 1 against falling out of the groove.

The reinforcing element is preferably used for reinforcement of narrow, web-shaped Parts of otherwise plate-shaped Building materials, but also to reinforce the edge areas of such Serve materials. This is especially with already prefabricated Countertops, stone or similar hard material z. For example Kitchen countertops, advantageous because the break vulnerable Edge areas thereby additionally reinforced can be, is it for the transport or the later Commitment.

Instead of The embodiments illustrated in the drawings, the outer contour of the reinforcing element also have other suitable forms. For example, in place of the band-shaped Inner core used an inner core with a circular cross-section be, in which case the sheath is an annular cross-section with circular outer contour having. Also, for example, trapezoidal or triangular cross-sections for the reinforcing element suitable.
