Method for manufacturing and mounting of prefabricated composite panel for floor box in building, involves establishing insulator between beams, so as to leave free spaces between beams and above insulator

摘要

The method involves preparing a flat panel (3) by machining grooves (4) on a side of the panel intended to be visible, and fixing beams (2) on the other side of the panel. An insulator (6) is established between the beams, so as to leave free spaces (7) between the beams and above the insulator, and to obtain a prefabricated composite panel (1). The prefabricated composite panel is transported to a building site, and a board (8) is installed on the beams, so as to close the free spaces between the beams.
