Description

TECHNICAL PART

The present invention relates to a mounting system according to the preamble of the independent claims and a device mounted therewith.

DESCRIPTION OF THE PRIOR ART

From the DE 951 422 B are known measures for the production of stiffened components, which include the inclusion of stiffening ribs in a resin matrix. This results as a completely enclosed, internal endoskeleton a stiffening component, which can be regarded as a general state of the art.

From the DE 24 02 023 C3 a stiffening ring is known, which is poured onto a connecting sealing element, cured and connected via anchoring members with an upper edge. Subsequent or additional stabilization of the sealing element is not possible here.

The DE 8600928 U1 proposes to stiffen a mounting plate, this build on a metal plate with a build-up plastic sheet to coat. A disadvantage of this measure is that here each plastic plate is stiffened with a lot of material with a metal plate inside a frame.

The DE 41 18 998 A1 teaches to form a stiffening rib of a component of a ventilation or line system in the interior of a volume flowed through as a plastic molding. This document relates to the particularly relevant field of generic ventilation or piping systems, which are usually made of composite and / or connected plastic elements. A disadvantage of the proposed stiffening ribs that they become brittle over time, jump and can break through, without this being visible from the outside. Such a stiffened plastic element can lose its rigidity completely, without this being recognized by the outside, optical control.

Object of the present invention was therefore to overcome the disadvantages of the prior art and to provide a mounting system which is able to provide a lower material cost in combination with an adjustable and quickly verifiable stabilization despite good stabilization of plastic elements on stiffening ribs.

The solution of this task is carried out according to the features of the independent claims. Advantageous embodiments will become apparent from the dependent claims and the following description.

SUMMARY OF THE INVENTION

According to the invention, the mounting system comprises interconnected plastic plates, stiffening elements and plastic moldings; the stiffening elements are formed as longitudinally extending ribs and connectable to the plastic moldings by means of rear grip; the plastic moldings consist of a plastic compatible with the plastic plates and are thermoplastically directly or via a connecting, thermoplastic plastic layer with the plastic plates to be stiffened outside connectable.

DESCRIPTION OF THE INVENTION AND ADVANTAGEOUS CHARACTERISTICS

Plastic plates are extensively extended and possibly adapted to a contour or spatial form plastic plates; This includes spatial forms such as concave and / or convex curved segments, arched or curved plates or half-tubes and also annularly curved and / or welded plate segments.

Stiffening elements are formed as longitudinally extending ribs and thus have a length which is significantly greater than the thickness or width; the simplest and most economical form is straight extending in the longitudinal direction. However, the rib can also be adapted to the spatial shape of plastic plates to be stabilized or ductile-plastically adapted to advantageously stabilize the required spatial form true to form.

Plastic moldings are projecting plastic sections, which will occupy only a fraction of this surface connecting to the outside surface of the plastic plates to be stabilized.

The stiffening elements can be connected to the plastic formations by means of a rear grip. By non-positive, mechanical connection of outside stiffening element and plastic molding on the one hand and non-positive and cohesive connection of plastic molding and plastic plate on the other hand, a non-positive stabilization of the plate is achieved by the outside stiffening elements. The plastic moldings consist of a plastic compatible with the plastic plates and are thermoplastic directly or via a connecting, thermoplastic plastic layer cohesively - ie via a continuous continuous, material connection - connected to the plastic plates to be stiffened. Advantageously, the formation can be attached and connected detachably to a stiffening element via known measures with small-surface energy input. This offers the advantage that a stiffening also later optically controlled, adapted to changing requirements, supplemented, repaired or even completely removed, which was not possible in the prior art so far.

Preferably, the mounting system is characterized in that the stiffening elements consist of metallic C-profiles. A C-profile provides a double-sided rear grip parallel to the extension direction of the profile, whereby the adhesion is more uniform and stable and advantageous in the plastic malleability of the metal is also adaptable to curved spatial forms.

Preferably, the mounting system is characterized in that the plastic moldings are formed as massive sections of an H-profile. Advantageously, different stiffening elements, particularly advantageously different, metallic C-profiles of different sizes, can be connected on the outside to the plastic moldings via thermally connected H-profile sections at different distances from each other. This advantageously allows zonal to be adapted to different loads with different stiffening elements stabilization.

Preferably, the mounting system is characterized in that the stiffening elements are formed connectable via additional slots. Slotted holes allow, due to their additional, linear extent, the insertion or passage of fasteners along the center line of the respective slot; Advantageously elongated center lines are aligned obliquely to a connecting line of two connection points, so that by pivoting the stiffening element even with inaccurate arrangement of connection points always a connectivity can be achieved. Particularly advantageous is a connection at several connection points via at least partially elastic fastening means, which introduce an additional stabilizing stress in the connection and a stiffening element.

Preferably, the mounting system is characterized in that the plastic plates comprise thermoplastic materials and as thermoplastically welded, rectangular housing and channels - possibly with tubular connecting elements - are present. Rectangular spatial forms offer the advantage that they can be arranged side by side in a particularly space-saving manner and checked together; Particularly advantageous in conjunction with cross-over, elastically braced stiffening elements, which are connected to several different plastic plates of different housing and / or channels, a rapid and extremely effective review of the plates and housing can be performed by vibration resonance of the entire unit.

Preferably, the mounting system is characterized in that the plastic formations have central holes that are spannungsbeaufschlagend behind with screws and / or nuts. This allows - particularly advantageous in curved spatial forms - the additional application of tensile and / or compressive stresses at individual connection points between stiffening elements and plastic moldings.

Preferably, the mounting system is characterized in that the plastic plates are connected to at least one base body, the plastic moldings are formed as externally thermally weldable H-profile sections and the stiffening elements as metal C-profiles with slots to form a stabilizing, connected exoskeleton Plastic formations engaging behind and the body are stabilizing mountable. An exoskeleton surrounds - in the same way as stabilizing chitin glands in insects - more plastic and / or more elastic basic bodies. The exoskeleton envelops the body (s) and will channel external forces into the entire skeletal structure and at least partially compensate for it elastically. As a result, basic body are better protected against shocks, shocks and vibrations and are advantageously stabilized in their relative arrangement and connection with each other. In the case of metallic, narrow stiffening elements, the base bodies are furthermore particularly advantageously accessible, so that even repairs to / in the base bodies can be carried out without a complete disassembly of the exoskeleton being necessary. The thermally weldable formations in this case advantageously allow the subsequent installation and clamping of spare parts or additives in an existing exoskeleton.

Preferably, the mounting system is characterized in that the plastic plates to housings and channels of a gas by pressure difference transporting system - preferably ventilation system - are connected. Especially in this area a subsequent adaptability - which is often required in ventilation systems - advantageous to carry.

Further advantages emerge from the exemplary embodiments. It is understood that the above, preferred features, advantages and subsequent embodiments are not restrictive. Advantageous or preferred additional features and additional combinations of features, as explained in the description, can be realized within the scope of the independent claims in the claimed subject matter either individually or in a different manner without departing from the scope of the invention.
