Definitions

• the invention relates to a sheet steel door, in particular in fire protection training, with a box forming the door leaf broad side and a cover forming the other door leaf broad side, which is connected at its edge regions to edge strips of the box edges projecting outwards parallel to the broad side plane, in particular by spot welding, whereby an edge section of the edge regions of the lid or the edge strips of the box edges adjoining the connection zone to the outside is angled to form the stop area of a fold toward the box and overlaps the connection zone.
• a thick rebate door of conventional design also consists of a box and a cover, the box being designed to be less deep by approximately the fold thickness if the thickness matches that of the thin rebate design.
• the lid has in its edge areas protruding from the box a web bent at right angles from the lid plane and then a stop area angled towards the box, which engages over the edge strips of the box and with its freely tapering edge into the angle area between the box body and the edge strip engages.
• tack welding takes place, which is disadvantageous because of the possible welding spatter and burn-up.
• the invention has for its object to provide a thick rebate door made of box and lid, which is much easier to handle and less problems with regard to the type of connection between the box and lid.
• this object is achieved in that the edge section forms a first bend forming a web that determines the thickness of the fold in width, and then a second bend forming the stop area. has an ending bend which overlaps the connecting zone at a spacing of approximately web width.
• the design of the thick rebated sheet steel door according to the invention is based on the idea of enabling spot welding with regard to handling and in particular also to protect against corrosion by initially failing to completely convert the cover into its finally angled configuration with regard to its pre-folded edge region, so that the connection zone between the edge strip of the box and the edge region of the lid is accessible perpendicularly thereto after the box has been placed on the lid, so that a spot welding device can be attached accordingly. Only after spot welding has been carried out is the prepared, folded stop zone of the lid further bent onto the box, so that the stop area of the fold overlaps the spot welded connection zone between the edge strips of the box and the edge area of the lid.
• connection between the lid and the box is made possible by spot welding and that one can do with a simple placing of the box on the lid or vice versa and thus avoids the annoying pushing together of the box and the preformed lid.
• the design according to the invention is shown as an example from FIG.
• the box identified overall by 1
• This state is shown on the left in FIG. 1.
• spot welding is carried out between edge strips 4 of the box 1 and edge regions 3 of the lid 2; this is indicated by correspondingly schematized tool reproduction in this left part of the figure.
• the edge area 3 of the cover 2 is pre-folded in its edge section 6 adjoining the outside via the connection zone to form a thick fold, specifically after the connection zone with a web 8 and a stop area 9 adjoining it at right angles, the ends in a stiffening edge 10 which is in turn angled by more than 90 ° and faces the connecting zone 5 - spot welding zone.
• the web 8 which roughly determines the thickness of the fold, is only bent by an angle of less than 90 ° in preparation for the cover plane, so that the spot welding tool can effortlessly reach the connection zone between the cover and the box.
• the edge section 6 of the edge region 3 of the cover 2 is then bent further into its final position such that the web 8 is bent at right angles to the cover plane.
