AI Technical Summary

Technical Problem

Existing facade layer elements with thin front panel elements are prone to deformation and cracking due to uneven moisture distribution and environmental stresses, leading to defects and reduced structural integrity.

Method used

A facade layer element design comprising a supporting wall element, an insulating layer element, and a front panel element with a textile-containing reinforcement and short fibers, held together by rods and inclined anchors, which distribute stress and prevent cracking by maintaining uniform moisture distribution.

Benefits of technology

The design effectively prevents deformation and cracking of thin front panel elements, ensuring structural integrity and reducing visible defects, while allowing for large, prefabricated facade elements with improved tensile strength and insulation properties.

Abstract

The invention relates to large-format facade layer elements, comprising a supporting shell, insulation, and a (slim, constrained) facing panel element made of textile-reinforced concrete, and to the production thereof. A facade layer element (1) is proposed, comprising at least one supporting wall element (2), at least one insulation layer element (3), and at least one facing panel element (4), wherein the at least one facing panel element (4) is arranged at a distance from the at least one supporting wall element (2), and the at least one insulation layer element (3) is arranged between the at least one supporting wall element (2) and the at least one facing panel element (4), wherein the at least one facing panel element (4) can be or is fastened to the at least one supporting wall element (2) by means of a plurality of holding means (5, 6), wherein the plurality of holding means (5, 6) extends through the at least one insulation layer element (3).wherein the at least one facing slab element (4) comprises a facing concrete mass (7) with a textile-containing reinforcement (9), the at least one facing slab element (4) has a maximum thickness of 8 cm and the facing concrete mass (7) additionally has short fibers (8), the short fibers (8) having a length between 3 mm and 20 mm.,
