A drainage hole floor module and a method of production of such

摘要

The invention regards a method of production of a drainage hole floor module (1) to a floor structure (13) of a building site (27) and a modular plate member (1) per se. The method comprises the step of providing a forming tool (41) for manufacture of a plate member (5) comprising a thermosetting polymer. The member (5) has an extended lower surface (9) and an extended upper sloping surface (17) converging to an apex point (AP). In a further forming step is made permanently joining of a drainage pipe (19) rigidly to the thermosetting polymer, wherein an upper end (45) of said drainage pipe (19) is positioned at said apex point (AP). The modules are transported as bulk cargo to the building site and are simply installed.
