Sheet metal with punched structures for connecting two wooden elements, composite of two wooden elements with the sheet metal and method for producing the sheet metal

Abstract

The present disclosure relates to a sheet metal for joining two wooden elements, the sheet metal having punched structures each having a hole with a diameter of less than 5 mm, preferably less than 3.5 mm, more preferably less than 2.5 mm, and four teeth projecting from a main surface of the sheet metal distributed around a circumference of the hole. The punched structures are provided on both main surfaces of the sheet metal. At least in the majority of the punched structures, preferably in all punched structures, all teeth of a respective punched structure project from the same main surface of the sheet metal. A number of the punched structures on the one main surface is at least 90%, preferably 100%, of a number of the punched structures on the other main surface.
