Description

Component system for the construction of switchboards

The invention relates to a component system for Construction of switchboards, with rectangular compartments for holding measuring and operating devices, grid-shaped composable elements.

Such a component system should have as few elements as possible and allow the compartment arrangement for the accommodation of devices, in particular according to DIlT 43700, to change at any time and with the least possible impact on the environment.

Such a component system is according to the invention characterized by angle elements with isosceles! .- profile, where at the ends of the legs and along the angular edge and perpendicular to it in an integral division of the element width matching, rectangular incisions are attached and the parts of the angular edge and the leg ends that have remained between the incisions have edge-parallel 'aligned' transverse bores; Rod elements made of flat profile, .of the same width and n times the length of the angle legs, which fit at their ends in an integral division of the element width have rectangular cuts and transverse bores; nail-like fasteners that when interlocking Joining the ends of angle and / or rod elements can be inserted into the aligned transverse bores. The center axis distance from cross hole to cross hole corresponds in a preferred embodiment a standardized Grid dimension or a multiple thereof.

With the help of the angle elements, the rod elements of various Length suitable for both horizontal and vertical installation and the nail-like connecting elements control panels can thus be built using grid technology, where the first setup and later Changes can be made quickly and easily.

To explain the invention, exemplary embodiments are shown in the figures of the basic elements and a panel cut-out constructed with them and shown below described.

FIG. 1 shows an isosceles angular element 11. The integer division of the element width b should be ten here, ie the surfaces of the limbs 12 and 13 are to be thought of as being divided into ten parallel subsections 1. As can be seen, the rectangular incisions 16 run from the angular edge 14 into both legs in the subsections 2, 4 to 6, 8 and 10. The end of the leg 12 has incisions 16 in the subsections 1 to 3 and 5 to 9, that of the leg 13 in the subsections 1, 3 to 7f 9 and 10. The parts with the part numbers 3 _f 7ι 9 in the angular edge 14 »4 and 10 at the end of the leg 12 and 2 and 8 at the end of the leg 13 have edge-parallel, aligned transverse bores 15, the purpose of which will be explained later. The center axis distance 1 from the transverse bore 15 to the transverse bore 15 corresponds to a grid dimension of preferably 72 mm.

FIG. 2 shows a rod element 22 made of a flat profile, which can be used both in a horizontal and in a vertical arrangement. The rod element 22 has the same width b as the angle element 11, its length

can be η times the distance3 1, where η goes from 1 to 4. A rod element 22 is shown in FIG Length 2x1 between the axes of the outer cross holes 25. The ends of the rod element 22 are provided with incisions 26 in a manner similar to that of the Winkeleleraent 11, those at the end 23 in sections 1 to 4, 6 to 7 and 9 to 10, at the other end 21 in the sections 2 to 4 and 6 to 10 are. The remaining parts with part numbers 5 and 8 or 1 and -5 in turn have the transverse bores 25, they are arranged such that they are in the incisions 26 of adjacent Angle elements and / or adjacent rod elements fit. The rod element 22 can also 180 ° around its Rotated longitudinal axis can be used. The remaining parts then have the part numbers 3 and 6 or 6 and 10, the incisions 26 in between take the place of the remaining sections. For rod elements of length η χ 1, with ns 2, are in each case at a distance 1 rectangular recesses 27 attached in the area, corresponding to the integer division 1 ... 10 are executed and have the transverse bore 25 in their central axis. In the illustrated embodiment, the recesses 27 are in the subsections with the number 3 and 4 »6, 9 and 10. or when rotating by 180 ° at 1 and 2, 5, 7 and 8.

The depth of the incisions 16, 26 or the length of the recesses 27 is greater than the material thickness d in the case of angle element 11 and rod element 22. This achieves that to facilitate handling when inserting or removing the elements from the association the same can be easily tipped in.

A nail-like connecting element 31, shown in FIG. 3 , serves to connect the angle elements with one another or between angle elements and rod elements

at the joints between two or more elements those that are in alignment when they are joined together Cross bores 15, 25 is inserted.

FIG. 4 shows a section of a control panel constructed with the aid of the aforementioned elements. The grid consists of angle elements 11 and rod elements 22 ^ 22 ₂ , 22 ,, 22 single length, double, triple and quadruple length L. At the nodes, the individual elements are attached to one another with the nail-like connecting elements 31.

There are nodes in the structural design or when setting up switchboards in this grid technology in which more than two bar elements collide, there are two that differ in the division of the incisions Types of rod elements in the building element system to be provided.

Angle and rod elements can also be other than those indicated in the figures and dimensions of the have interlocking ends.

In a preferred embodiment, the dimensions of the elements are chosen so that when they are assembled, compartments with internal dimensions according to DIN 43700. The compartments not occupied by devices are covered with cover plates in the Basic grid dimension closed.

Large switchboard units constructed using this grid technology are advantageously mounted on a simple frame hung up.
