Definitions

  • the invention relates to a door leaf member of a ceiling sectional door, a multi-part door leaf moved vertically or horizontally in its closed position or the like multi-part building closure with the features of the preamble of claim 1.
  • Known lamellar door leaf members which are made of thin sheet metal, are welded together with lateral reinforcing struts running in the direction of movement of the door leaf and optionally also with one or more reinforcing struts arranged evenly distributed between them. This is usually done by spot welding or by a comparable welding process using welding nipples. This presupposes that the areas of the sheet metal lamella to be welded and the respective reinforcing strut are not electrically insulated from one another. If such insulation were already provided for the individual parts, for example in the form of a primer for the lamellar plate and / or the reinforcing strut profiles, then this would have to be removed.
  • the invention has for its object to provide a door leaf member of the type mentioned, which is much easier and much more resistant to environmental influences and less noise.
  • connection technology provided according to the invention between the sheet metal lamella and the reinforcing struts ensures that the parts brought together to form the dimensionally stable door leaf member, namely the sheet metal lamella on the one hand and the reinforcing struts on the other hand, are joined after the lamella sheet has been completely coated, stove-enamelled or otherwise finished with a surface treatment.
  • the reinforcing struts can be provided with surface protection before being joined to the lamella sheet.
  • the profile struts preferably consist of essentially U-shaped profiles which are cut to length. It is preferable to use galvanized sheets. As far as the cut edges remain unprotected, this has no more serious significance, because rust developing there does not impair the stability of the struts and does not appear to the outside.
  • the reinforcing struts are thus glued to the sheet metal lamella of the door leaf member in the finished surface-treated state, specifically over a large area, so that a stable mounting is achieved.
  • This gluing is limited to the inner surface of the sheet metal lamella lying in the level of the door leaf.
  • the C-shaped bends that limit the sheet metal lamella perpendicular to the direction of the door leaf movement are not included in this bond. Due to the thin sheet used, the shape of this bend is low. For this reason, the reinforcing struts are positively connected with end sections projecting in their longitudinal direction to the edges of the bend lying in the door leaf plane, in such a way that an existing surface treatment, coating, application of paint or the like does not interfere with this either.
  • the end sections of the reinforcing struts overlap in parallel the inside of the edges of the C-shaped bend and are connected to the edges in this area by the fact that on one of the adjacent parts perpendicular to the door movement direction, tab-like projections are provided, which are in one in the other Intervene in part of the opening provided and engage behind the edges which run approximately perpendicular to the direction of movement of the door.
  • the play between the projections and the opening in the door leaf movement direction is kept small, so that the spacing of the edges of the upper and lower unwinding of the metal plate is fixed via the reinforcing struts.
  • the reinforcing struts provided in the two edge regions of the sheet metal lamella extending in the direction of movement of the door leaf are provided with a cladding, which has the function of a reinforcing profile.
  • This cladding is preferably pushed onto the door leaf member from the side, namely by clasping the respective lateral reinforcing strut and the edge region of the sheet metal laminate glued to it.
  • the reinforcement profile overlaps the entire length of the respective edge region of the door leaf member and thus overlaps the end sections of the reinforcement strut and thus also the regions of the edges of the lower and upper C-shaped development of the sheet metal plate located there.
  • An engagement flap is punched out in the overlap area in such a way that it turns after it has been turned protrudes into the opening in which the two projections already engage.
  • the dimensioning is such that the width of the engaging flap punched out in the direction of movement of the door leaf has approximately the distance between the two projections engaging in the opening.
  • the reinforcement profile is held almost free of play against lateral movements to the door movement direction and can therefore not be removed from its deferred position or the clasping.
  • the screws additionally pass through correspondingly aligned bores in stops of threads which in this area articulate the successive door leaf members.
  • the adhesive layer is preferably of a certain thickness.
  • the adhesive itself is in particular permanently elastic, i.e. even after the "hardening" in a way resilient. This makes another special contribution to preventing noise.
  • the door leaf member 1 is formed from a sheet metal lamella 2, which on its longitudinal edges pointing in the direction of movement of the door leaf formed from a large number of such door leaf members 1 are provided with a C-shaped bend, which - FIGS. 2, 4 and 5 - initially from the inner surface 8 the sheet metal lamella 2, which lies in the door leaf level, is bent in steps at right angles and ends in an edge 6, which in turn runs parallel to the door leaf level.
  • the edges 6 of the two bends 3 formed on the longitudinal edges 4 are directed towards one another with their free ends.
  • This sheet metal lamella 2 is kept stiffened in the form described above with the aid of reinforcing struts 7.
  • reinforcing struts 7 arranged on the edge regions 5 of the sheet metal lamella 2 running in the direction of movement of the door leaf are encompassed by reinforcing profiles 18, as will be explained in more detail in connection with FIG. 5.
  • These reinforcing struts 18 cover the edge areas 5 in a box-like manner and reinforce the edge areas 5 of the door, on the bottom panel of which a rope of a weight compensation device acts on both sides.
  • each reinforcing strut 7 consists of an essentially U-shaped profiled sheet, the legs 16 of which, in their free area, form bent edge webs 9, which describe a plane that describes runs parallel to the inside 8 of the sheet metal lamella 2.
  • Adhesive layers 10 made of an adhesive are provided between the outer sides of the edge webs 9 of the reinforcing struts 7 facing this inner surface 8 and the adjoining area of the inner side 8, which adhesive also has permanently elastic properties after the setting, such that sound insulation in the transition area between the struts and the sheet metal lamella 2 is given or this is held on the struts 7 in a vibration-damped manner by the large-area strip-shaped adhesive layers 10.
  • the sheet metal lamella 2 is provided in the area between its C-shaped bends 3 with beads 11 running parallel thereto, which run approximately perpendicular to the reinforcing struts 7 extending in the direction of movement of the door leaf. In the area of these beads, they face the inside 8 of the sheet metal lamella 2
  • the ends of the legs 16 of the struts 7 are provided with cutouts 12, which encompass the bead 11 that passes through with a relatively large amount of play, so that no special requirements have to be made with regard to the manufacturing accuracy with regard to the adaptation between bead 11 and cutout 12.
  • the edge webs 9 of the struts 7 are interrupted, as can be seen in FIG. 2.
  • the adhesive layers 10 are limited to the edge webs 9, so that adhesive and non-contact gap zones are formed between the recesses and the beads.
  • the dimension of the legs 16 to the web 17 of the U-shaped strut profile connecting them is such that the connecting web 17 with respect to its two end sections 13 provided on the front side on the surfaces of the edges 6 running parallel to the inside of the reinforcement profile 18 is present, as can be clearly seen in FIGS. 2, 4 and 5.
  • a rectangular opening 15 is provided, which preferably extends further in the longitudinal direction of the longitudinal edges 4 and thus the edges 6 of the bends than perpendicular to it.
  • a punching is provided corresponding to an opening 15, through which two tab-shaped projections 14 directed towards one another in the direction of the longitudinal edge are formed, each of which is bent around the adjacent, short edge of the opening 15 extending in the door leaf movement direction , for which express reference is made to FIG. 4, which clearly shows this clasping or reaching behind the narrow opening edges 15 through the projections 14 by a corresponding opening of a partial area of the contact zone between an end section 13 and an edge 6.
  • the width of the projections 14 and the length of the short edges of the opening 15, around which the projections 14 are bent, are coordinated with one another in such a way that a displacement movement of the strut 7 with respect to the C-shaped bend is prevented at least approximately without play.
  • the two C-shaped bends 3 in the two longitudinal edges 4 of the sheet metal lamella 2 are kept constant in shape via the struts 7 and form a transportable, stable, open-sided box construction. It is thus possible to transport and store a sheet metal lamella freshly glued to the struts and positively connected in the manner described above.
  • the two struts 7 provided on the edge regions 5 running in the direction of movement of the door leaf are encompassed by a reinforcing profile 18, each of which, from the side, onto the strut and the wall zone of the sheet metal strip bonded thereto, holding these bonded parts between them, in the manner of clips is postponed.
  • the reinforcement profile is held in this pushed-on position by punching out an engaging tab 20 projecting in the direction of movement of the door leaf in the region of its two front ends 19, in such a way positioned that the engaging tab in the shoulders of the bent projections 14 between the shoulders facing each other free space of the opening 15 in the associated edge 6 can be introduced by turning; this bent position is shown in dashed lines in Figure 5.
  • the width of the engagement flap seen perpendicular to the door leaf movement direction is dimensioned such that the distance to the adjacent curvatures of the projections 14 is as small as possible. This ensures that the laterally pushed-on reinforcement profile is secured against slipping on the sheet metal lamella 2. Since the cladding reinforcement profile 18 is provided with embossments in the longitudinal direction of the edge regions 5 of the lamella 2 for reasons of stability, it is advisable to facilitate the ability of the engagement flap to be bent out of the profile plane by a bending zone opening 21 shown on the right in FIG. 5.
  • the abutting areas of the bends 3 of the sheet metal lamella 2 - edge 6 -, the associated end sections 13 of the reinforcement profiles 7 and - in the case of the edge areas 5-end areas 19 of the reinforcement profiles 18 each have bores 22 provided, one each seen in the direction of the longitudinal edge 4 on both sides of the openings 15 or projections 14 and possibly the engaging flaps 20. In the contact area, these bores 22 are aligned with one another, so that two screw bolts can be inserted through the bores per connection point.
  • the bolts pass through corresponding bores in a connecting tab of a hinge which bridges the two connecting areas in an articulated manner.
  • the screw bolts pass through the bores 22 without a hinge flap being present.
  • connection of the parts of the door leaf member is therefore designed in a variety of ways, first of all over a large area using a sound-absorbing adhesive, then by engaging protrusions or tabs in openings to stabilize the spatial shape and transportability of the individual door leaf member and finally immovably and in a known manner secured against breaking apart, when the door leaf members are assembled into a door leaf.
  • the particular advantage of the formation of the door leaf member according to the invention lies in addition to its noise damping in that the individual parts can be safely surface-treated before assembly against weather influences such as rust formation and the like, without this disrupting the assembly.
  • the sheet metal fins can already be provided with a stove enamelling, a coating or the like as a flat band and only then can they be deformed into the lamella profile. In addition to the rust-protected design of the door leaf member, this leads to a considerably simplified production.
