EP0758700B1 - Multi-purpose building element with spring elements - Google Patents

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 building block consisting of a large number of components with the others Features of the preamble of claim 1.

From EP 0 576 939 a plastic multi-purpose component is known, which with other, similar multi-purpose components are built into a flat composite can. There are narrow expansion joint elements between the individual multi-purpose components inserted, which 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 to compensate for temperature-related expansion or shrinkage additional expansion joint elements required

The object is solved by the characterizing part of patent claim 1 Embodiments of the invention are realized by subclaims 2-14.

The multi-purpose component according to the invention is divided into individual flat sections that by integrally molded into the multi-purpose component - and not additionally attached - Spring elements are connected to each other when temperature fluctuations occur can change the position of the individual surface sections 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 suit each distance of the surface sections Timely guaranteed. The multi-purpose component two-dimensional composite thus has an internal flexibility and that with temperature fluctuations desired adaptability.

Another advantage of the spring elements integrally molded into the multi-purpose component consists in a certain tolerance compensation when laying the flat composite of the individual multi-purpose components can take place to each other

Advantageously, the spring elements are band-like and additionally loop-shaped, which allows for extensive flexibility and yet solid cohesion Multi-purpose component is achieved

By attaching the spring elements to the outer areas and between the individual Surface sections of the multi-purpose component secure the individual spring elements and protected and the wear processes are minimized when walking on 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 being connected via spring elements stand The four surface sections are by pressing together, pulling apart or pivoting 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 Point area facing each other in pairs, creates a particularly balanced designed multi-purpose component, which thermal expansion forces of different Pages can take.

The multi-purpose component laid out in the plane advantageously enables a different one 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 of the laid out in the plane Multi-purpose component in the vertical direction also serves to compensate for Thermal expansion and facilitates laying the multi-purpose component in hilly terrain

Adjacent multipurpose components are easily plugged together of 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 during the spraying process the cross or longitudinal struts of the multi-purpose component in the cross-sectional profile executed with essentially constant (and thin) thickness

Due to a widened standing area, the cross or longitudinal struts have sufficient Contact surface around the displacement movements that occur during thermal expansion to be able to perform and in addition any possible between cross or longitudinal struts secure the filling material (e.g. earth or ballast) against slipping.

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

Loop-shaped spring elements 3 are assigned to each other in pairs and 3 'are used, the central regions 6 of which face away from one another for connection Several multi-purpose components 1 are coupling devices 7 (for corresponding Coupling elements 8 for clamping connection with adjacent multi-purpose components Production of a flat composite) on outer areas 5 of the surface sections 2, 2 ', 2 '' and 2 '' 'are provided.

Fig. 2 shows the multi-purpose component 1 in a state in which the individual Surface sections 2, 2 ', 2' 'and 2' '' are staggered and rotated. By spreading the spring element 3, for example, or by compressing it the spring element 3 'is still a reliable connection between the surface sections 2 and 2 'guaranteed

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

The surface section 2 is pivoted relative to the surface section 2 '' '. Yet is a connection through the connecting and adapting spring elements 3 'to each Time guaranteed.

The cross section of a transverse or longitudinal strut 4 advantageously consists of FIG. 4 from a (uniformly) narrow head region 11 and a widened one Stand area 10, the latter the slipping of the surface sections relative to the Surface made easier to compensate for thermal expansion.
