COMPOSITE PANEL WITH LIGHT TRANSPARENCY PROPERTIES AND METHOD FOR MAKING SAID PANEL

摘要

The present invention relates to a composite panel (1) made of pourable and settable material, preferably cementitious mortar. The panel comprises through elements (10) made of glass for transmitting light between two base surfaces (1,1′) of the panel (1). The panel comprises a structure (5) made by sintering heat-expanding plastic material about said through elements (10) so that a central part (12) of said through elements (10) is incorporated into said structure (5). The panel further comprising a first main portion (23) and a second main portion (24), each of which incorporates an end part (13,14) of the through elements (10). The two main portions (13, 14) are connected by a plurality of through portions (25) in said base material which extend through the inner structure (5). The present invention further relates to a semi-finished product (8) for making said panel (1) and to a method for making said panel base on the use of said semi-finished product (8).
