A panel-like structural component for gates, doors, facings or the like includes a main wall and a frame surrounding the main wall. The frame is composed of sectional members with hollow rectangular cross sections whose inner walls facing the inside of the frame have at least one groove at least in the longitudinal direction of the matter. The grooves of all longitudinal members open into each other and form a continuous peripheral groove into which a panel forming the main wall is inserted at its edges. The grooves are also used to join two sectional members together: the groove, which becomes wider toward its interior, is engaged at one of the sectional members with a projection formed on a connecting piece fastened to the other sectional member. The connecting piece is made up of a segment of another sectional member. The structural component can be produced with little labor and material; it is stable and lightweight and can be disassembled to simplify repair in the event it is damaged. |
