DE1609973C - Made of sheet metal and designed as a hollow profile rung for glass roofs or the like - Google Patents

Description

The curved areas 19 merge into the areas 18 directed approximately perpendicular to the plane of the side wall.

The two longitudinal edges of the sheet metal strip are bent over by 180 ° to form hollow folds 22 and 23. The free leg 20 or 21 of each hollow fold 22 or 23 engages in the hollow fold 23 or 22 of the the other longitudinal edge of the sheet metal sheet, creating a double overlap that creates a secure connection the longitudinal edges of the sheet metal strip guaranteed.

Load-bearing capacity can be formed in a simple manner from a single patent application sheet metal strip without the need for any reworking, such as subsequent galvanizing of screw holes 1. Manufactured from sheet metal, and as a hollow profile 5 are. ■ trained rung for glass roofs or the like. According to the invention, this task is thereby geeiner solves in their contact surface for the glass panes that formed from a single sheet metal strip provided against this tapered rung in their contact with a support member Groove, which for anchoring the fastening wall another screw against the support member serves for a cover rail, thereby identifying io young groove for anchoring a on this, that it has a fastening screw that engages and that the rung (1) formed on each sheet metal strip passes through on the one of the two longitudinal edges of the sheet metal strip a support member (12) adjacent wall (3) is bent by 180 ° to form a hollow fold, further free legs tapering towards the support member (12) for closing the hollow profile Narrowing groove (6) for anchoring one on this 15 of the rung in each case in the hollow fold of the other engaging fastening screw (10) has the longitudinal edge engages. and that each of the two longitudinal edges of the sheet metal by the arrangement of a groove in the on the tape by bending by 180 ° to a hollow support member adjacent wall of the rung need in fold (22 or 23) is deformed, the free one of which does not have any holes for any fastening legs (20 or 21) to close the hollow ao screws are provided, which are subsequently profiled of the rung (1) must be zinked into the hollow fold (23). In addition, the rung or 22) of the other longitudinal edge engages. with the specified interlocking of their two longitudinal 2. rung according to claim 1, characterized in a very simple way from a single character that the sheet-metal strip is made to be parallel to each other and has due to the running side walls (4) of the rung (1) 25 through the two Grooves formed material accumulation areas (18 or 17) to BiI- gen a relatively high load-bearing capacity.
formation of the support surface (2) for the glass panes In an advantageous embodiment of the invention (14) approximately perpendicular to the plane of the side walls are the parallel to each other (4) to the outside and then in opposite side walls of the rung connecting the loading direction are curved inward. 30 rich. to form the support surface for the glass 3. rung according to claim 2, characterized thereby about perpendicular to the plane of the side walls draws that between the 'parallel to each other outwards and then in opposite directions extending side walls (4) of the. The rung (1) is bent inwards. Due to the double lying material and the adjoining, approximately vertical - the support surface is particularly stable to the side wall plane extending ready 35 staltet. chen (18) each inclined to this plane. In a further embodiment of the invention, between outwardly curved area (19) is provided, the sides running parallel to one another, walls of the rung and the adjoining, approximately perpendicular to the side wall plane -40 each of the areas is angled to: this one Outwardly curved area provided.
· ■ ·· ■ '■■■ ·. ■■ - ■ · ■ The drawing shows a cross section through a Part of a glass roof with an inventive Rungs shown. 45 The rung 1 is formed without cutting as a closed hollow profile from a single sheet metal strip. she consists essentially from the support surface 2 for the Glass panes 14, from which the support member 12 facing The invention relates to a wall 3 made of sheet metal as well as from the two side walls 4. and designed as a hollow profile rung for 50. The support surface 2 and the wall 3 each have glass roofs or the like with one in their support surface one in the longitudinal direction running out of the wall for the glass panes, shaped and tapered towards the outside, tapering groove that is intended for the anchoring of Be ^: groove 5 and 6 respectively. These grooves 5 and 6 are used for fastening screws for a cover rail. Recording and support appropriately shaped Such a rung is already known from the German 55 nuts 7 or screw heads, which are in the Nu patent specification 316 454. They consist of two pieces of sheet metal, 5 and 6, which can be moved along the rung 1 as required, so that the fastening screws 10 are connected to one another in a protruding manner, in accordance with the corresponding bores 9, although this connection also does not require Cover rail 11 and in the z. B. is particularly reliable by a roof. Furthermore, the support member 12 formed by this purlin must come,
