Abstract

The multipurpose construction part (1) is divided into individual surface sections (2). These are connected to each other via spring elements (3), which are integral with the part. The spring elements are loop-shaped, and located on the outside (5) of the individual sections. The elements are located in pairs, and the loops (6) face away from each other. The sections are movable relative to each other due to the spring elements, esp. turnable and/or relatively offset.

Description

The invention relates to a plastic multi-purpose component as a component egg nes consisting of a large number of components with the other Features of the preamble of claim 1.

From EP 0 576 939 a plastic multi-purpose component is known, which with other Ren, similar multi-purpose components are built into a flat composite can. Between the individual multi-purpose components are narrow expansion feet inserted genetic elements, which are caused by temperature fluctuations compensate for the areal composite consisting of several multi-purpose components.

The invention is based on the object of offering a multi-purpose component, which does not compensate for temperature-related expansions or shrinkages any additional expansion joint elements required.

The object is achieved by the characterizing part of patent claim 1. Before partial embodiments of the invention are real by subclaims 2-14 lized.

The multi-purpose component according to the invention is divided into individual surface sections that by integrally molded into the multi-purpose component - and not additionally attached brought - spring elements are connected. When tempe occurs Variations in temperature can result in changes in the position of the individual surfaces Chenabschnitte in relation to each other by spreading or pushing the molded spring elements are balanced.  

The connection of the individual surface sections with each other is due to the position of the spring elements to match the respective spacing of the surface sections guaranteed the time. The multi-purpose component two-dimensional composite thus has an internal flexibility and that of a temperature swan desired adaptability.

Another advantage of the spring elements integrally molded into the multi-purpose component is that there is a certain tolerance when laying the flat composite equal to the individual multi-purpose components can take place to each other.

The spring elements are advantageously band-like and additionally loop-shaped formed, which provides a high degree of flexibility and yet solid cohesion of the Multi-purpose component is achieved.

By attaching the spring elements to the outer areas and between the individual NEN surface sections of the multi-purpose component, the individual spring elements si cher and protected and there is a minimization of wear gears when walking or driving onto the multi-purpose component.

In a particularly advantageous embodiment, the multi-purpose component consists of four Surface sections, the individual surface sections via spring elements in Ver bond. The four surface sections are pressed together, apart pull or swivel the spring elements when installing the multi-purpose component different tolerances of the neighboring multi-purpose components adaptable and take in addition, the change in position of the individual that occurs during temperature fluctuations  Surface sections to each other. The attached inside the multi-purpose component Spring elements point outwards with their central areas and form a spray channel for injection molding the multi-purpose component.

Setting up the surface sections due to thermal stresses becomes reliable locked out. By using loop-shaped spring elements whose The tip area facing each other in pairs is particularly balanced gen designed multi-purpose component, which thermal expansion forces of different Pages can take.

Advantageously, the multi-purpose component laid out in the plane enables an under different movement of the individual surface sections in the horizontal direction both in terms of twisting as well as in terms of displacement.

An additional pivoting of the individual surface sections out in the plane placed multi-purpose component in the vertical direction also serves to compensate Thermal expansion and facilitates laying the multi-purpose component in hilly Terrain.

Adjacent multipurpose components are easily interconnected stuck from hook-shaped coupling devices in recesses and Clamp lock releasably connected to each other.

In a material-saving version and to achieve short cycle times when spraying the transverse or longitudinal struts of the multi-purpose component in cross-section ver run with essentially constant (and thin) thickness.

Due to a widened standing area, the cross or longitudinal struts have one sufficient contact area around the displacement movements that occur during thermal expansion gene to be able to perform and in addition anything between transverse or longitudinal str  filling material taken up (e.g. earth or gravel) to prevent it from slipping chern.

Environmentally friendly, the plastic of the multi-purpose component consists of shredded parts and then melted plastic waste into an appropriate shape is sprayable or pourable.

The invention is based on an embodiment in the drawing figures, he purifies. Show it:

Fig. 1, made up of four area portions 2 shows multipurpose component 1 with transverse or longitudinal struts 4. The individual surface sections 2 are arranged at outer portions 5 spring members 3 each connected ver.

Loop-shaped spring elements 3 assigned to one another in pairs are used, the central regions 6 of which are facing away from one another. Coupling devices 7 (for corresponding coupling elements 8 for clamping connection with adjacent multipurpose components for producing a flat composite) are provided on outer regions 5 of the surface sections 2 for connecting a plurality of multi-purpose components 1 .

In the interior of the multi-purpose component 1 according to FIG. 1, four spring elements 3 with center regions 6 pointing inwards form a spray channel 9 .

Fig. 2 shows the multiple use building element 1 in a state in which the individual surface sections 2 offset to one another and are arranged twisted. By spreading, for example, the right spring element 3 or by compressing the left spring element 3 , a reliable connection between the surface sections 2 is still guaranteed.

The spring elements 3 (not designated in any more detail) between the further surface sections 2 assume a suitable position and continue to ensure the connection of all surface sections 2 of the multi-purpose component 1 .

The surface section 2 is pivoted relative to the adjacent surface section 2 . Nevertheless, a connection is guaranteed by the connecting and adapting spring elements 3 at each point in time.

The cross section of a transverse or longitudinal strut 4 according to FIG. 4 advantageously consists of a (uniformly) narrow head region 11 and a widened standing region 10 , the latter facilitating the sliding of the surface sections relative to the substrate to compensate for thermal expansion.
