Description

The present invention is a reinforcing material for reinforcing the undercoat layer, particularly a reinforcing material that can be wound and deployed in the form of a sheet, preferably a reinforcing cloth, wherein the reinforcing material is a plurality of elongated spacers, preferably spacers. It has a molding material, preferably substantially parallel to each other and at predetermined intervals from each other, extending within and / or along the reinforcing material. The spacer containing the reinforcing material relates to the reinforcing material, which predefines the minimum layer thickness of the undercoat layer.

The general types of reinforcements mentioned above are disclosed in German Patent Application Publication No. 3926366. This publication describes a reinforcing mesh to reinforce the wall undercoat, which is expected to be placed approximately one-third from the outside of the undercoat thickness, for this reason. It has a plurality of spacers that fix the position of the reinforcing mesh surface relative to the surface to be formed. The spacer is an elongated molding material that is oriented parallel to the reinforcing mesh surface, extends parallel to each other, and has a cross section corresponding to the desired distance from the surface to be primed. , The molding material forms one structural unit together with the reinforcing mesh. That is, a reinforcing mesh integrated with the spacer is obtained, which can also be provided to the construction site as a roll product in a rolled state and is deployed for incorporation into the undercoat.

In particular, a similar reinforcing cloth with a spacer woven into a string in the cloth is disclosed in German Patent Invention No. 102005040090.

In both cases of known reinforcing fabrics, the spacer is a solid molding material that is circular in its cross section and is particularly dimensionally stable. This is advantageous for ensuring the function of spacing.

An object of the present invention is to improve the ease of handling and particularly the transportability of the reinforcing cloth having a spacer.

This object is achieved by the present invention in which the spacer has a take-up facilitation design but is reliable in its function of spacing.

That is, the present invention is surprisingly original that the contradiction between the winding capacity and transportability and space-saving storage of the well-known reinforcing cloth and the purpose is precisely based on the reliable dimensional stability of the spacer. Identified by various methods.

Thus, the solution according to the invention advantageously provides a better compatibility between winding capacity and reliable spacing.

The reinforcing material according to the present invention, which is obtained by the first embodiment of the solution according to the present invention, is a plurality of spacers, preferably arranged at regular intervals from each other, over the longitudinal extending lengths of the plurality of spacers. It features a material cut, preferably a notch.

The cut portion according to the present invention is preferably formed by a sawtooth-shaped spacer lath, which remarkably facilitates winding of the reinforcing material according to the present invention. At the same time, a preferably dimensionally stable material protrusion that defines the notch or other material cut is perfectly suited to ensure the ability to be spaced. In addition, the teeth are preferably primed to penetrate into the primer compound to the surface directly supported by the primer when the stiffener is normally pushed into and placed in the first primer layer. , Better suited.

Spacers according to the invention can be made using various bonding techniques, especially from materials that are easily bonded to fabric materials, such as polyvinyl chloride.

Alternative embodiments of the invention or, where appropriate, additional embodiments also feature spacers with variable cross-sectional contours in the direction of the undercoat coating thickness extending approximately perpendicular to the reinforcing surface. And.

Specifically, a roll of generally relatively thin reinforcing cloth with spacers may have a much larger diameter than the reinforcing cloth without spacers as a result of the additional radial protrusions of the spacers. This greatly makes handling, transportation and storage of common reinforcing cloths with spacers difficult.

Such spacers according to the invention can be realized, for example, by having a hollow cross section resulting from a material that is elastic to some extent flexible but elastically upright or spreads again, whereby the spacers exert a force. In addition, they are crushed together while being wound up and refolded when the reinforcements are unfolded. It should be pointed out that during undercoating, the spacers are preferably spread so that no excessive force acts on the spacers in the direction of the surface to be primed. This is because an accurately uniform minimum layer thickness can be achieved. Spacers according to the invention having the correct shape and material settings can easily withstand such spreading forces without compromising their reliable spacer function.

One preferred embodiment of the invention features a cross-sectional contour of a spacer having at least one region that is folded open approximately parallel to the reinforcing surface.

This particularly concise and advantageous scheme allows a predetermined area of the spacer according to the invention to be folded open so that it can be laid substantially flat and wound up. When the stiffener is unfolded, the area is preferably automatically re-upright. The above is already true for this purpose, that is, by being preferably spread during the undercoat, no excessive force is exerted on the spacer in the direction of the surface to be undercoated, i.e. during the undercoat. There is no risk of the area being bent or folded.

This is also true if the bendable region is a substantially lath-shaped design, as is preferably provided under the present invention.

In this case, in one preferred embodiment, the cross-sectional contour of the spacer according to the present invention may have a substantially L-shape.

The L-shaped base can be applied flat as a strip to a reinforcing material, especially a reinforcing cloth, and bonded to it in a particularly simple manner. In this case, the lath or L-shaped second leg projects substantially perpendicular to the spacing. In order to wind up the stiffener, a predetermined load is applied so that this upright lath is exactly on the L-shaped base or in a plane adjacent to the L-shaped base so that it is even flatter. Can be folded flat.

Another embodiment of the spacer according to the invention results in that the bendable area is designed or arranged to automatically stand upright.

That is, advantageously, when the stiffener and / or its coupling region, that is, the joint or hinge region, is expanded, the region itself can automatically erect, eg, bend in the upright direction. It can be appropriately designed to apply prestress to possible areas. This can happen exactly, especially in the hinge region with plastic, as opposed to, for example, membrane hinges. Membrane hinges with certain material weakening sections facilitate folding, while beaded or sausage-like thickening sections, for example, may make folding even more difficult. This is possible, and on the other hand, it can also support or support and promote uprightness again.

One other embodiment of the invention is characterized in that at least the bendable region and / or the binding region for the bendable region is formed from a so-called storage material.

For example, metal alloys having the desired properties are available on the market and may be incorporated and used in plastic materials, especially if desired. However, there are already plastics, especially polymers, that exhibit such properties in their own right.

Additionally or optionally, in one alternative embodiment, the stiffeners according to the invention have at least a bendable region and / or a binding region for the bendable region, as already described above. It may be characterized by being formed from an inherently elastic and flexible material. Preferably, the material for at least one secondary region of the spacer may be plastic, preferably PVC.

Although another feature of the invention can be obtained from the plurality of exemplary embodiments, these embodiments should be considered in principle as merely examples, and the subject matter of the invention or the scope of protection of the invention shown in the illustration. Is not limited to.

It is a basic enlarged sectional view which shows the substrate with the undercoat layer which has the reinforcing material by this invention. Another enlarged end-view view showing an upright position of a spacer according to the present invention for a reinforcing material as shown in FIG. 1. It is a figure which shows the spacer shown in FIG. 2 in the position which laid flat.

FIG. 1 shows a basic enlarged cross-sectional view of a substrate 1 provided with a surface to be primed with an undercoat layer 2 having a reinforcing material 3 according to the present invention. The reinforcing material 3, especially the reinforcing cloth, has a plurality of spacers 4, and the spacers 4 are arranged at regular intervals from each other and extend in parallel with each other, and these spacers are substantially. Designed as an L-shaped forming material, preferably extending substantially along the entire width or overall length of the cloth web.

In the enlarged view shown in FIG. 1, the substrate 1 is merely shown in a schematic manner and is shown in an interrupted form. The reinforcing material 3 is inserted or pushed into the undercoat layer 2 so that the reinforcing material 3 is accurately located approximately 1/3 from the outside of the layer thickness of the undercoat layer 2. For example, the spacer 4 can preferably predefine a minimum layer thickness of approximately 5 mm between the reinforcing material 3 and the substrate 1, and the thickness of the undercoat layer on or outside the reinforcing material 3 is still approximately 2 mm. May be.

The use of the reinforcing material 3 and the coating of the undercoat layer 2 are preferably performed as follows, for example.

First, an undercoat layer 2 (particularly reinforced mortar), preferably approximately 5-7 mm, is manually or mechanically applied to the substrate 1.

The stiffener 3, especially the stiffener, is then cut, i.e. measured and appropriately cut to fit in particular, and positioned in the primer layer 2 in front of the spacer 4 and pushed into the primer layer 2.

Preferably, a batten is used at this time, whereby the reinforcing material 3 is pushed together with the spacer 4 until the spacer 4 supports the surface of the substrate 1 or comes into contact with the surface of the substrate 1. It may be embedded even more flat inside. Next, or at the same time, the undercoat is removed on the removal line formed by the spacer 4, so that excess material is removed, leaving a minimal amount of material to cover the reinforcing web. If the coating thickness is extremely thin, the primer or mortar is applied later (additionally) and removed again, if appropriate.

In this way, while maintaining the minimum layer thickness, the production of uniformly and planarly primed panels is facilitated and accelerated.

Depending on the selection and design of the spacer material according to the present invention, alkalinity, combustion behavior, loadability with respect to humidity and temperature, etc. can be considered particularly advantageously.

FIG. 2 shows another enlarged end-view or cross-sectional view showing the spacer 4 according to the present invention for the reinforcing material 3 as shown in FIG. 1 in an upright position. In terms of functional position, the spacer 4 substantially has an L-shape formed by a hinge joint 7 connecting the foundation leg 5, the spacer leg 6 and both legs 5, 6.

The foundation leg 5 is positioned flat with respect to the reinforcing cloth of the reinforcing material 3, and is immovably bonded to the reinforcing cloth of the reinforcing material 3, for example, by adhesion, stitching, welding, or the like.

At the functional positions shown in FIG. 2, the spacer legs 6 ensure the correct undercoat spacing between the stiffener 3 and the substrate 1.

FIG. 3 shows the spacer 4 shown in FIG. 2 in a flatly laid position. In this case, the spacer leg 6 is folded flat from its functional position into the plane of the foundation leg 5 and is aligned with the foundation leg 5. At this support position, the reinforcing cloth can be wound up in a space-saving manner, and the flat spacer 4 can also be wound up.

The hinge joint 7 allows the spacer leg 6 to fold open, but at the same time provides prestress for the purpose of automatically erecting the spacer leg again to the functional position in the direction of arrow 8.

That is, a predetermined load is required to lay the spacer 4 flat and wind up the reinforcing material 3 together with the spacer 4, and the elastic force is released again in order to erect the spacer leg 6 during deployment. It has become so.
