Definitions

  • the invention relates to a profiled steel frame with a laterally arranged hinge rod and a laterally arranged lock bar as well as a head bar connecting the hinge bar to the lock bar.
  • the ribbon rod, the lock rod and the head rod are formed from a steel profile.
  • the head bar rests against one another with the band bar and / or the lock bar in a corner area with a miter cut.
  • Door frames are used to enclose a building opening which can be closed by means of a door leaf.
  • a frame has two lateral bars, which are arranged laterally next to the doorway in a lateral direction and aligned in a vertical direction, and which are also referred to as a hinge rod and a lock rod.
  • the hinge rod is formed by that side rail on the side of which the door leaf is attached to the frame or a wall surrounding the wall opening by means of door hinges.
  • the opposite spar is also referred to as the lock rod, with door locks and / or latches usually located on this side.
  • the crossbeam which connects the two side rails and is arranged in the vertical direction above the doorway is also referred to as the head bar.
  • a door leaf that closes the doorway rests on three sides against the hinge rod, the head rod and the lock rod.
  • the door frame and / or the door leaf can be designed with a rebate at which they interlock in stages.
  • the invention is nonetheless also suitable for butt-hinged doors.
  • Particularly robust and resistant door frames are formed from metal profiles, in particular from sheet steel. These have a high temperature resistance and are themselves non-flammable. Steel frames in connection with door leaves from a filled or unfilled sheet metal box are therefore often used as security doors or as fire doors.
  • corresponding endless profiles are produced - for example by edging a sheet metal strip - and then cut to the required length for the hinge rod, lock rod and head rod.
  • the profiles have an identical cross-section so that they can be set against one another with a 45 degree miter cut.
  • the steel profile has at least one mirror section and one passage section. Furthermore, areas can be formed which serve to form or receive a fold and / or to receive seals and functional elements. This allows the metal profiles to take on complex shapes to form a steel frame.
  • the invention is based on the object of improving the connection in the corner area between the head bar on the one hand and the hinge bar or the lock bar on the other hand in a profiled steel frame.
  • the connection should be established with little expenditure of time and money and should ensure high stability and secure alignment of the metal profiles.
  • the head bar is connected to the hinge bar and / or the lock bar by an angled shoe attached to the end of the respective steel profile.
  • the at least one angle shoe extends into at least one end of the head rod and into one end of the ribbon rod or the lock rod.
  • the angle shoe is shaped in such a way that it rests positively on an inside of the steel profile forming the head bar and on the other hand positively on an inside of the further steel profile that forms the hinge bar or the lock bar.
  • the shape of the angle shoe is designed in such a way that the desired angled arrangement between the steel profiles is ensured through correct insertion and fastening.
  • the angle shoe is attached directly to both steel profiles, so that direct welding of the two steel profiles to one another is not necessary. Is within the scope of the invention It is possible to avoid an expensive weld seam between the heavily profiled steel parts and to replace it with an additional part through a robust and reliable indirect connection.
  • the profiled steel frame is particularly preferably designed as a block frame.
  • Block frames are located completely within a doorway and do not protrude beyond this in the lateral direction, the vertical direction and in either direction perpendicular to the doorway. They are therefore particularly easy to assemble compared to surrounding frames. As a result, the individual profiles of the frame can be completely assembled in advance. For assembly, they are simply pushed into the doorway in the direction of passage and fixed there.
  • the angle shoe is particularly preferably screwed to the steel profiles.
  • a screw connection has the advantage that it can also be produced directly on site during installation without complex additional equipment such as welding equipment.
  • a steel frame according to the invention can thus be provided as a kit in a particularly space-saving manner.
  • This comprises at least one angle shoe as well as a head rod, a band rod and / or a lock rod forming steel profiles.
  • these and / or the angle shoe can be designed or pre-drilled with through holes.
  • Screws in particular self-tapping self-tapping screws, can be screwed into this for fastening.
  • the screws are particularly preferably designed as flat head screws which are screwed into the metal profiles and the angle shoe on the outside.
  • the head of the flat head screw has a maximum height of 2 mm, preferably a maximum of 1 mm so that the screw heads can be accommodated in the assembly gap between the door frame and the wall.
  • the angle shoe is formed from a single piece of sheet metal, in particular sheet steel.
  • Sheet metal is a durable and at the same time inexpensive material. This can be processed with the same machines as the sheet metal strips for producing the steel profiles for the steel frame. In particular, a workpiece with high intrinsic stability can be produced by edging a sheet metal.
  • the angled shoe particularly preferably has a first angular section and a second angular section bent at right angles thereto.
  • the first angle section is followed by a first tab, which is bent at right angles with respect to the first angle section.
  • the first tab also extends at right angles to the second angular section.
  • the first tab is - directly or indirectly - connected, preferably welded, to the second angular section.
  • the first bracket fixes and stabilizes the first angular section and the second angular section in their position bent by 90 degrees relative to one another.
  • the angle shoe is thus suitable for giving the steel frame the necessary stability in the corner area and for ensuring reliable alignment of the head bar with respect to the hinge bar or the lock bar.
  • a second bracket adjoins the second angular section, which tab is bent at right angles with respect to the second angular section.
  • the first flap and the second flap run flush with one another, that is to say in one plane.
  • the second tab is with the first tab connected, preferably welded.
  • the first tab and the second tab abut one another with two mutually facing end faces, whereupon the connection is established.
  • the first tab and the second tab each have a miter cut with which they rest against one another.
  • the miter cut of the flat tabs can be welded more easily and reliably than the profiled frame elements.
  • both the first tab and the second tab can be designed to be essentially rectangular in order to simplify the manufacturing process and to reduce costs.
  • the first tab extends on the first angular section right up to the fold to which the second angular section adjoins.
  • the first flap is then attached directly to the second angular section with one end edge.
  • the second flap does not extend directly to the fold, but ends in front of it at a distance which corresponds to the width of the first flap.
  • the folded second tab is then attached with its end face to a longitudinal edge of the first tab facing away from the first angular section. The production of a miter cut can be avoided here.
  • a form-fit connection is preferably formed in the connection area between the first tab and the second tab.
  • a form-locking projection is formed on the first tab or the second tab, which positively engages in an associated form-locking receptacle of the second tabs or the first tab.
  • the form-fit connection is designed, in particular, for tensile stress in order to prevent the first tab and the second tab from being pulled apart - and thus preventing the angle shoe from bending open.
  • compressive forces can also be transmitted by the first tab being flush with the second tab.
  • the form-fit connection at least supports the cohesion between the first tab and the second tab.
  • the connection of the tabs can be formed exclusively by the form fit - with the omission of a welded connection. This enables a particularly flat and level construction without a raised weld seam.
  • the steel profile (of the head bar, the hinge bar and / or the lock bar) preferably has a door-side mirror section, an adjoining passage section facing the doorway, and an adjoining mutual mirror section.
  • the angled shoe lies flat with the first tab and / or possibly the second tab on an inside of the door-side mirror section or the mutual mirror section. In this way, a large-area support can be achieved, which contributes to the stability of the steel frame.
  • tabs are arranged on both sides of the first angle section and / or on the second angle section in the passage direction, which are flat both on the inside of the door-side mirror section and on the inside of the mutual mirror section rest.
  • the angle shoe is thus held positively in the passage direction in the door profile and can transmit forces on both sides through support.
  • the steel profile (of the head bar, the hinge bar and / or the lock bar) preferably has a first fastening section adjoining the door-side mirror section and bent over in the direction of the mutual mirror section and / or a second fastening section adjoining the mutual mirror section and bent over in the direction of the door-side mirror section on.
  • the angle shoe with the first angle section rests flat against the inside of the first fastening section and / or the second fastening section.
  • the angle shoe thus fills the corner area of the steel frame with a positive fit and can optimally transfer forces.
  • a trim profile can also be attached to the first attachment section and the second attachment section, which is arranged on a side of the steel frame facing away from the doorway and increases its insertion width or height.
  • the first fastening section and the second fastening section expediently run in one plane. According to a preferred embodiment, they are not connected to one another and in particular have a spacing.
  • the interior of the frame profile is accessible from the outside facing away from the doorway. This makes it easier to insert and correctly position the angled shoe.
  • the angle shoe bridges the distance between the first fastening section and the second fastening section, as a result of which the steel profile is additionally stabilized.
  • the angle shoe is connected to the steel profiles (of the head bar and the lock bar or the ribbon bar) exclusively at the first fastening section and / or at the second fastening section.
  • a screw connection is preferably provided for the connection, which can also be released again later.
  • the Fig. 1 shows in an oblique perspective a wall surface 1 with a wall opening 2 arranged therein, which is surrounded by a profiled steel frame 3 according to the invention.
  • the wall surface 1 extends substantially in a lateral direction x and a height direction y.
  • a passage through the wall opening 2 is possible in a passage direction z.
