Abstract

Bath galvanized substructures for rear‐ventilated façades – part 1 Thin‐walled steel components (0.8–2.5 mm) for substructures according to DIN 18516‐1 can be produced using galvanisation. Brackets and support profiles remain warp‐free, the thickness of the zinc layer is above the standard acc. to DIN EN ISO 1461. Flanging on the edges of the holes in the brackets and lateral edging increase the load‐bearing capacity, as do increasing sheet thicknesses. Load‐bearing profiles are also strengthened by lateral edging; U‐ and hat‐profiles are on top. Experimental tests in the climatic chamber revealed a gradation of the perforated brackets; the most favourable design is the bracket with three slotted holes. Thermal and mechanical tests have proven that galvanized components represent a static, thermal and economical alternative to commercially available substructure systems. [ABSTRACT FROM AUTHOR]

Abstract

Wall and roof components made of steel sandwich elements are firmly established in industrial and commercial construction. They are cost-effective and characterized by excellent physical properties. Here, hybrid approaches from heating- and cooling ceiling construction were examined for the solar thermal activation of sandwich elements. Besides the implementation of the solar components, the connection to and the optimization of the system technology was focused. In addition, alternative piping materials were investigated numerically and experimentally. The performance as well as the static and thermo-hydraulic behavior of the new active components were simulatively and experimentally examined, and the economic viability of the variants was also checked. With the newly developed solar sandwich elements, an overall energy concept was developed with connection variants to the building services system, control and storage technology. Steel sandwich elements with mineral fiber core are well suited for the hidden integration of component parts such as pipe registers and heat conducting plates. The functionality of the component has been proven, the implementation of heat exchanger leads to considerable heat gains. In combination with a brine-to-water heat pump system, the solar panel can provide for a more sustainable operation and a significant size reduction of the geothermal source.
