Description

[0001] The invention relates to a spacer block, in particular a concrete block, for receiving and fastening a structural element, in particular a cable tray.

[0002] Spacer blocks are frequently used in roof and floor mounting as spacers or support elements for mounting systems. These include, in particular, cable tray systems, pipelines, rail systems, or support structures for photovoltaic modules.

[0003] In the prior art, spacer blocks are known that are equipped with anchor rails or integrated mounting rails. These serve to indirectly fasten cable trays or other structural elements. Systems with transverse mountings or fixing shoes are also common.

[0004] However, such solutions have several disadvantages. They require additional components such as metal rails or mounting rails, which makes assembly complex. Furthermore, the separation of the materials used is more difficult, which impairs reuse and recycling. Additionally, extra transverse slots or recesses can make manufacturing more complex and weaken the stone's load-bearing capacity.

[0005] It is therefore an object of the invention to overcome at least one of the aforementioned disadvantages. In particular, a spacer block for a cable tray system is to be provided that enables the simple fastening of structural elements, especially cable trays, without requiring additional fastening rails, exhibits improved recyclability, and at the same time allows for easy handling.

[0006] The problem is solved according to the invention by a spacer stone having the features of claim 1. Preferred embodiments of the invention are specified in the dependent claims and the following description, each of which can individually or in combination represent an aspect of the invention.

[0007] According to the invention, the spacer block has at least one longitudinally extending fastening slot into which a fastening screw can be directly screwed, by means of which the mounting element can be fixed directly to the spacer block. This enables direct and simple fastening without the need for additional fastening elements such as anchor rails or inserted metal rails.

[0008] "Directly screwable" means that the fastening screw is inserted directly into the concrete of the fastening slot, without intermediate elements such as dowels, screw strips or screw shoes.

[0009] The spacer block is preferably made of concrete. Here, "concrete block" refers to a block made of normal concrete, lightweight concrete, or polymer concrete. Choosing this material ensures high strength and stability of the block, while also allowing for economical production.

[0010] It is particularly preferred that the side walls of the fastening slot have no openings running transversely to the slot depth. This has the advantage of achieving a particularly stable construction of the spacer block and simultaneously distinguishes it from known systems with transverse slots, where separate fastening elements must be used.

[0011] In a further advantageous embodiment, the fastening slot can be provided for in the spacer block exclusively from one side. The fastening slot can be formed during the manufacture of the spacer block by inserting a formwork or core, or subsequently created from the top side by machining processes such as sawing or milling.

[0012] The spacer stone can also be advantageously manufactured using the continuous casting process.

[0013] In a particularly advantageous embodiment, the fastening slot has a width of less than 10 mm, preferably less than 8 mm, and most preferably between 4 mm and 8 mm. This allows for the secure insertion of commercially available fastening screws while simultaneously preventing excessive opening of the concrete body.

[0014] Preferably, the mounting slot has a depth of 40 - 60 mm, particularly preferably 45 - 55 mm.

[0015] In a further advantageous embodiment, the spacer stone has a length of 200 to 600 mm, a width of 100 to 200 mm, and a height of 80 to 150 mm, preferably weighing 5 to 30 kg, and more particularly weighing 10 to 15 kg. These dimensions ensure that the spacer stone offers sufficient stability while still being manageable by one person and can be positioned on a flat roof or floor area.

[0016] To ensure the secure fixing of the assembly element, it is further specified that the fastening screw is a concrete screw and preferably the fastening screw is used together with a washer to fix the assembly element. This achieves a particularly strong connection of the assembly element to the spacer block.

[0017] To enable a continuous fastening line, it can be provided that the fastening slot is formed continuously over the entire length of the spacer stone.

[0018] This facilitates the flexible positioning of screws and the alignment of the respective assembly element.

[0019] In a further advantageous embodiment, the spacer block has a recessed grip on each of two opposite sides, preferably on its longitudinal sides. The recessed grip is groove-shaped and preferably has a semicircular cross-section. It preferably extends along the entire length of the spacer block. This improves the ergonomic handling of the spacer block, particularly during transport and installation.

[0020] To protect the contact surface, it is preferably provided that the spacer block is equipped with a protective covering on its underside, which is made of foam, preferably an elastic foam such as foam rubber. The protective covering is detachably, and preferably snap-in, attached to the spacer block, with several, preferably four, snap-in fastening elements preferably being provided, which are arranged in the area of ​​the corners of the spacer block. The fastening elements are preferably formed by cuts in the protective covering itself, so that elastic locking tabs are created that grip the spacer block. Preferably, the protective covering extends over the entire underside of the spacer block and projects laterally beyond it, thus providing a large and simultaneously protective contact surface.

[0021] This ensures secure fixing of the protective layer while allowing for easy disassembly. Furthermore, it reliably prevents damage to sensitive roof waterproofing and guarantees easy separation of the stone or concrete layer from the protective layer, thus improving recyclability.

[0022] In a further advantageous embodiment, the invention relates to a fastening system comprising a spacer block and a fastening screw, wherein the fastening screw can be screwed directly into the fastening slot of the spacer block for fastening an attachment element. This ensures simple and material-saving assembly.

[0023] The invention further relates to a fastening system comprising a spacer block and a mounting element, wherein the mounting element is fixed directly in the mounting slot of the spacer block by means of a fastening screw. This achieves a direct connection without intermediate elements.

[0024] In an advantageous embodiment, the mounting element is a cable support system, in particular a cable tray, a rail, or a pipe. This particularly supports the main application of the spacer block in the area of ​​cable routing.

[0025] In a further advantageous embodiment, the cable tray rests directly on the spacer block with its base and is fixed in the mounting slot by fastening screws passing through the base. This results in a particularly stable and secure attachment of the cable tray to the spacer block.

[0026] In another embodiment, the assembly element is a photovoltaic module or another energy generation or energy conversion element. This enables the use of the spacer block in the field of energy installations, particularly on flat roofs.
