Method and device for producing a translucent multilayer composite construction element with integrated facade panel

Abstract

Method for producing a heat insulating, light conducting multilayer composite construction element for facades of building structures and the like, in which the multilayer composite construction element consists of at least one layer of a curable casting compound and at least one heat insulating layer of insulating material, and all layers are penetrated by light conducting elements, whereby a.) in a first process step the light conducting elements are fixed in an insulating body forming the heat insulating layer b.) in a second step the light conducting elements fixed in the insulating body are inserted in a formwork space of a formwork formed by formwork panels and c.) in a third step the formwork space is filled with a curable casting compound, forming at least one support layer, whereby b1.) the formwork panels used in the second step are designed as permanent formwork elements consisting of facade panels provided with drill holes or recesses, in which the front sides of the light conducting elements are received at least partially.

Description

technical field [0001] The invention relates to a method and a device for producing a translucent multilayer composite building element with integrated facade panels, and to a translucent multilayer composite building element with integrated facade panels produced by the method. Background technique [0002] EP 1970179A 2 discloses a method and an apparatus for the production of translucent multilayer composite building elements. This document is incorporated herein by reference in its entirety, such that this application includes the entire content of this document. [0003] In the aforementioned publication, translucent multi-layer composite building elements are produced by first inserting rigid light-guiding rods into drilled holes in an insulating body so that the ends of the light-guiding rods are guided from opposite Both surfaces protrude. [0004] The base body thus produced is then placed in a formwork, the formwork space of which is provided with a curable casti...

AI Technical Summary

Problems solved by technology

But this has the disadvantage that it is very difficult to align the drilled holes in the façade with the front of the light guide rods fixed on the surface layer

In addition, it is also very difficult to connect the exterior wall panels with the surface layer through binding and other means

[0010] In addition, since the thickness of the outer wall panel is, for example, between 2 and 5 mm, the drilled hole of the outer wall panel added in front is not filled into the light guide rod but only used as the space before the front side of the light guide rod. drilling is disadvantageous

First, this leads to undesired light loss as the light needs to travel further through the empty borehole and be scattered within the empty borehole

Secondly, the accumulation of dust and debris in the hollow boreholes can also cause problems. After a long period of use, such multi-layer facade elements can completely cover the illuminated front side of the glow stick due to the accumulation of dust and debris.
