Abstract: The present invention relates to attachment mean (1) for connecting plane components in dry construction, in particular for fixing two-dimensional construction material to a metallic substructure, having a shaft (2) on one end region of which a point (3) and on the other end region of which a head (4) are formed, a fine thread (5) being formed on the shaft (2) in order to increase extraction values of the attachment means (1), at least in regions, a number of grooves (6) being provided on the shaft (2) which extend substantially parallel to the central axis (X) of the shaft (2).

Abstract: An attachment means for connecting thin-walled roof or facade panels to a substructure has a shaft on one end region with a point and on the other end region with a head. A number of longitudinal grooves are provided on the shaft which extend parallel or substantially parallel to the central longitudinal axis X of the shaft. The head of the attachment means has a flat-head at a side of which facing the shaft a washer is formed, which radially protrudes outwards from the flat-head. A fine thread is formed on the shaft at least in some regions. Further the invention relates to a kit having such an attachment means and a sealing washer and a kit having such an attachment means and a sealing washer and a magazining-belt, respectively, and a method for connecting a thin-walled roof or facade panel to a substructure.

Abstract: Plate glass, in particular soda-lime plate glass, is treated with potassium water glass in order to alter the optical properties of soda-lime plate glass, in particular its reflection behaviour. The soda-lime plate glass is thermally treated after application of potassium water glass in order to achieve additional hardening of the soda-lime plate glass. The treated plate glass can be used, in particular, for cover plates of photovoltaic modules.
