Abstract

Aluminium profile for forming a substructure for stone, ceramic or natural stone slabs in unbound construction, characterized in that the profile has in cross-section at least one longitudinally extending channel (8) designed to receive a fastening means and at least one longitudinally extending horizontal bearing surface or a horizontal web (14), wherein the channel (8) is arranged in a defined vertical position relative to the bearing surface (14), such that when several identical or different profiles are combined within a substructure, the channels (8) form a common fastening plane and the bearing surfaces (14) form a common bearing plane for the slabs to be laid, so that a positionally identical fastening of different profile types is possible without additional compensating elements.

Description

Technical field

[0001] The invention relates to aluminum profiles for forming a substructure for slab coverings, in particular for terraces, balconies and flat roofs in unbound construction. The invention further relates to a profile set consisting of several compatible profile types (edge, intermediate and support profiles) which together provide a level support and fastening surface. State of the art

[0002] Substructures for tile coverings are known in which the tiles rest on profiles, and the profiles are connected via connectors. In practice, this often results in different connection levels between profile types, inconsistent heights, uneven fastening positions, and increased installation and adjustment effort. Edge finishes are often designed in such a way that tile ends or cut edges remain visible, or additional cover pieces and special profiles are required. Furthermore, water and dirt can accumulate in the area of ​​open joints if no suitable drainage system is provided. Task

[0003] The object of the invention is to provide aluminium profiles that enable a unified connection plane and a level support of several profile types, simplify assembly, provide defined fastening options and enable additional functions such as drainage and a high-quality edge finish. Summary of the invention

[0004] The problem is solved by an aluminum profile according to claim 1 and by a profile set according to claim 2. It is essential that the profile has in cross-section at least one longitudinally extending horizontal threaded channel (8) and at least one horizontal bearing surface or a horizontal web (14), wherein the positional relationship is chosen such that, when several identical or different profiles are supported against each other, the horizontal threaded channels (8) are in a common alignment and the upper bearing surfaces (14) form a common plane. This creates a uniform, system-wide usable fastening plane as well as simple assembly and alignment of the profiles. Advantageous embodiments

[0005] In preferred embodiments, the profile has at least one, and in particular two, longitudinally extending vertical threaded channels (7) for receiving threaded screws and are particularly suitable for fastening further functional elements (e.g., a joint cross receptacle). Furthermore, upper groove receptacles (9) and / or lower groove receptacles (10) can be provided to receive additional functional elements in a form-fitting or clamping manner. Connector bearing surfaces (15) can be provided for connection and assembly. In further embodiments, round threaded channels (6) are provided, in particular for end-face or position-defined fastening. A recess (12) can serve as a structural receiving or contact geometry. drainage

[0006] In a preferred embodiment, an opening (16) is provided in the area of ​​an open panel joint, which leads into a cavity (17) formed within the profile cross-section. The cavity (17) is connected to at least one through-opening arranged on the underside of the profile, so that water and dirt entering through the joint can be drained downwards. Edge finish

[0007] In a preferred embodiment, an edge profile (1) has a lateral, upwardly extending upstand (11) that forms a lateral boundary of the edge plate, inhibits its lateral displacement, and conceals the end face of the plate. Additionally, a cover (13) can be provided, which covers the cut edges of the plate and enables a visually closed edge termination. Brief description of the drawings

Fig. Figure 3 shows an intermediate profile (3) with two horizontal threaded channels (8) and two vertical threaded channels (7). Furthermore, upper groove receptacles (9), lower groove receptacles (10), horizontal webs / bearing surfaces (14) and connector bearing surfaces (15) are provided. For drainage, an opening (16) and a cavity (17) are formed, with the opening (16) leading into the cavity (17).
