Abstract
A frame for explosion-proof housings. The frame is assembled from support elements. The support elements may be square tubes that are used as support elements, which are provided with elongated rectangular openings, which are closed by flameproof grilles that are welded on or fastened in another manner. The square tubes are joined to form a skeletal frame, which supports the housing structure (support frame). The metal plates may be stainless steel or aluminum, or plastic plates that are fastened to the outside of the frame by bonding and/or welding so that the housing is closed. Venting openings, which can be closed by the flameproof grilles, are provided in suitable locations of the housing, such as at the bottom or at the end faces. According to the present disclosure, thin wall thicknesses of the surface elements, for example plates, as well as large housing dimensions, while ensuring a flameproof enclosure, are made possible by means of the supporting and stabilizing support frame, which also helps to reduce the pressure.
