Definitions

  • the invention relates to a support element according to the preamble of independent claim 1.
  • the invention relates to a method for producing a support element, wherein an upper chord and a lower chord are provided, after which an intermediate element having elevations and depressions is connected to the upper chord and lower chord by screws.
  • a support element having an upper chord, a lower chord and an intermediate element connecting the upper chord with the lower chord, the intermediate element being formed by a sheet metal having elevations and depressions, in particular a trapezoidal sheet, the intermediate element resting at least in areas on the upper chord and the lower chord and that Sheet metal is connected to the upper chord and lower chord by screws, with screw heads of the screws being arranged on the outside of the upper chord or lower chord and the screws being screwed into press-in nuts attached to the intermediate element, the upper chord and / or the lower chord being formed by hollow profiles, in particular square profiles.
  • the object of the invention is to provide a support element of the type mentioned, which can be produced particularly easily and inexpensively.
  • the first object is achieved according to the invention by a support element according to claim 1.
  • the elevations and depressions of the intermediate element usually extend at least partially in a plane which is normal to a direct connection between the upper chord and lower chord, i.e. generally transversely to a longitudinal axis of the upper chord and lower chord, so that a high one is also present in a direction transverse to the longitudinal axis Section modulus and thus high rigidity can be achieved.
  • the upper flange and/or the lower flange are formed by hollow profiles, in particular square profiles, preferably square tubes, which have tab openings in which tabs of the intermediate element are positioned.
  • hollow profiles in particular square profiles, preferably square tubes, which have tab openings in which tabs of the intermediate element are positioned.
  • This enables particularly simple assembly.
  • a support element ensures high rigidity in different spatial directions.
  • the tab openings generally have dimensions corresponding to the dimensions of the tabs and are preferably arranged on an upper side of the hollow profiles, in particular adjacent to a side surface.
  • the intermediate element therefore preferably has tabs which have a tab height that approximately corresponds to a profile height of the hollow profiles.
  • the profile height corresponds approximately to the length of the side surfaces of the hollow profiles. The tabs can then rest on the inside of the side surfaces of the hollow profiles in order to ensure a good frictional connection.
  • the tabs preferably have bores or approximately circular screw openings, on which the press-in nuts are arranged, around which the inside of the hollow profiles arranged tabs to be connected to the hollow profiles or upper chord and lower chord by screws, which screws are guided from the outside through the side surfaces of the upper chord and lower chord and screwed into the press-in nuts arranged on the tabs.
  • the tabs are therefore located between the press-in nuts on the one hand and the side surfaces of the hollow profiles on the other, which means that a particularly good pressure of the tabs on the inside of the hollow profiles can be achieved.
  • a particularly high rigidity of the support element is achieved when the tabs in the hollow profiles rest on the inside of the hollow profiles, preferably on opposite insides.
  • both the elevations and the depressions of the intermediate element can be connected to the upper chord and lower chord.
  • the tabs of the intermediate element thus preferably protrude through tab openings, which are arranged on the upper sides of the upper chord and lower chord, and lie on the inside of side surfaces of the upper chord and lower chord, which are usually formed by hollow profiles.
  • the side surfaces connect the tops of the hollow profiles with the undersides.
  • a distance between elevations and depressions of the sheet or, if the intermediate element is formed with a trapezoidal sheet, a height of the trapezoid corresponds to a side surface distance between side surfaces of the hollow profiles, which form the upper chord and / or lower chord.
  • a tab spacing in the transverse direction usually corresponds to a distance between elevations and depressions or, if the intermediate element is designed as a trapezoidal sheet, to a height of the trapezoid.
  • screw openings are arranged on the tabs, on which the press-in nuts are arranged, on a side opposite a contact surface of the intermediate element with the upper flange or the lower flange.
  • the screw openings which can also be designed as holes, are usually designed as through holes, so that the tabs arranged in the hollow profile are guided by screws, which are guided from an outside of the hollow profiles through corresponding bores or screw openings in the hollow profiles and in the tabs and screwed into the press-in nuts, flat between the press-in nuts and the side surfaces of the hollow profiles can be clamped. Appropriate clamping enables good power transmission.
  • the screw openings are preferably made into the sheet metal, which forms the intermediate element, by laser cutting, so that simple and reliable production is guaranteed.
  • a thickness of the sheet metal of the intermediate element and/or the hollow profiles can be, for example, 1 mm to 30 mm, preferably 5 mm to 15 mm. It goes without saying that this thickness is selected depending on an expected load, which in the case of a support can also be determined, for example, by a length, a span or a projection. Usually, the sheet metal or the intermediate element has approximately the same thickness throughout, which therefore generally corresponds to a tab width.
  • the screws and nuts are usually also dimensioned according to the expected load and can be designed with a nominal size of M10, M14 or M16 in order to achieve good pressure of the tabs on the hollow profiles.
  • the intermediate element has tabs spaced apart along a transverse direction, which are connected to opposite side surfaces of the hollow profile, preferably flat. In this way, a particularly high level of rigidity is also achieved in a transverse direction.
  • the tabs are thus spaced both along a longitudinal axis of the upper chord and lower chord and along a transverse direction, which is normal to the longitudinal axis.
  • tab openings and/or the screw openings are formed by laser cutting.
  • the tab openings in the upper chord and in the lower chord can be adjusted to dimensions in a particularly simple manner
  • Tabs can be adjusted in order to achieve a particularly precise connection of the tabs of the intermediate element to the upper and lower chords with a slight weakening of the upper and lower chords.
  • the screw openings which correspond to dimensions of screws through which the upper chord and lower chord are connected to the intermediate element, are also preferably introduced into the upper chord, lower chord and / or intermediate element by laser cutting.
  • the tab openings extend to a side surface of the hollow profile and have an opening width which corresponds to at least one tab width plus a height of the part of the press-in nut protruding from the intermediate element, the width preferably being less than the tab width plus a double Height of the part of the press-in nut protruding from the intermediate element corresponds.
  • the tab openings are preferably designed to be just large enough so that the tabs, together with the press-in nuts usually already arranged on them, can be inserted into the tab openings, but not much larger in order to minimize material weakening on the upper and lower chords.
  • the opening length of the tab openings is greater than the tab length of the tabs by less than 30 mm, preferably by less than 15 mm, in particular less than 5 mm.
  • the opening width of the openings is less than 30 mm, in particular less than 15 mm, preferably less than 5 mm, larger than the tab width plus the height of the press-in nut protruding from the tab.
  • the tab width corresponds to a sheet thickness of the sheet from which the intermediate element is formed.
  • tab openings are made into the hollow profiles by laser cutting, a corresponding dimension can be achieved in a particularly simple, process-reliable and precise manner.
  • the tab openings can therefore, for example, have an opening width of 15 mm to 30 mm.
  • An opening length of the tab openings usually corresponds approximately to a tab length of the tabs and can be, for example, 20 mm to 200 mm.
  • the intermediate element between the tabs which are positioned in the upper chord or in the lower chord, rests at least partially on an outside of the upper chord or the lower chord. It is therefore possible to transmit force not only at the tabs, but also along an area between the tabs, with contact usually taking place via an end face of the intermediate element to an upper side of the upper belt or lower belt.
  • the intermediate element can basically be formed in a variety of ways, for example by a welded construction with elevations and depressions. A particularly simple type of production is achieved if the intermediate element is formed by a bent sheet metal.
  • the intermediate element can have a sheet metal bent into a trapezoidal sheet metal or be formed by such a sheet metal sheet.
  • the intermediate element is usually connected to the upper chord or lower chord by press-fitting nuts and screws pressed into the intermediate element, which protrude through the upper chord or lower chord and screw openings in the intermediate element.
  • a support element according to the invention is easy to produce and at the same time has high rigidity and strength in different spatial directions. Accordingly, the support element can be used for a wide variety of purposes. It is particularly advantageous if a structure, in particular a carport or a building, which has a support, contains a support formed by a support element according to the invention. This means that the structure can be manufactured easily and cost-effectively, while at the same time achieving high rigidity and strength.
  • a contour of the intermediate element is formed at least partially, preferably entirely, by laser cutting.
  • the production of a contour of the intermediate element can be done, for example, by cutting out a substantially rectangular sheet metal with tabs optionally arranged on the top and bottom by laser cutting, the tabs being intended to be inserted into corresponding tab openings in the upper chord or lower chord and with the upper chord or lower chord, which preferably are designed as hollow profiles to be screwed together.
  • a contour is therefore understood to mean in particular a contour in a side view, i.e. in a projection direction along the transverse direction.
  • the contour of the intermediate element is formed by laser cutting before the intermediate element is bent.
  • the intermediate element is usually still designed as a flat sheet metal.
  • the elevations and depressions of the intermediate element can be formed in a variety of ways, for example by welding individual sheets. It is particularly easy to produce if the elevations and depressions of the intermediate element are at least partially introduced into a flat sheet metal by forming, in particular bending, preferably after the sheet metal has been cut.
  • the sheet is usually made of a steel, in particular a structural steel.
  • the sheet metal of the intermediate element is galvanized, preferably after the sheet metal has been bent.
  • the press-in nuts are pressed into the intermediate element after the sheet has been galvanized.
  • the upper chord, lower chord and intermediate element are usually connected and screwed together.
  • tabs of the intermediate element are preferably first guided into tab openings on the upper sides of the upper chord or lower chord and screws are guided from the outside through screw openings on the upper chord or lower chord and the intermediate element and screwed into press-in nuts arranged on the inside of the intermediate element adjacent to the screw openings.
  • the intermediate element is thus usually formed by first cutting the sheet metal by laser cutting, whereby the sheet metal is usually still flat, after which the sheet metal is bent, preferably into a trapezoidal sheet metal, after which the sheet metal is galvanized, after which the nuts are in the area of screw openings or Holes, which were usually made in the sheet metal by laser cutting during the cutting process, are pressed in, after which the intermediate element is screwed to the upper and lower chords.
  • a corresponding carrier can therefore be assembled on a construction site in a particularly simple manner.
  • the upper chord and lower chord as well as the intermediate element are usually manufactured in one production, preferably with an automated laser cutting device, with which tab openings in the upper chord and lower chord as well as screw openings in the intermediate element, the upper chord and the Lower flange are introduced and with which a contour of the intermediate element is cut from a flat sheet.
  • Fig. 1 shows upper chord 1, lower chord 2 and intermediate element 3 of a support element according to the invention in an only partially assembled state.
  • the upper chord 1 and lower chord 2 are each formed by a square tube and have tab openings 8 made by laser cutting, into which tabs 9 of the intermediate element 3 can be inserted.
  • the intermediate element 3 is formed by a sheet metal bent into a trapezoidal sheet having elevations 4 and depressions 5, which has tabs 9 which can be inserted into the tab openings 8 on the upper chord 1 and lower chord 2.
  • the tabs 9 each have a tab height 23, which is approximately a profile height 24 of the upper chord 1 and lower chord 2, i.e. a length of side surfaces 14 of the upper chord 1 and lower chord 2, which are formed here by square tubes. This ensures particularly good force transmission between the tabs 9 and the upper chord 1 or lower chord 2.
  • Circular holes or screw openings 10 are arranged on the tabs 9, on which press-in nuts 7 are positioned on the inside. How As can be seen, the press-in nuts 7 are arranged on one side of the tabs 9, which is opposite a contact surface 11 of the tabs 9.
  • the contact surface 11 is understood to be that surface on which the tabs 9 rest on the inside of the side surfaces 14 of the upper chord 1 or lower chord 2 in the assembled state.
  • Fig. 1 It can be seen that tabs 9 are arranged on both elevations 4 and depressions 5 of the intermediate element 3, which are thus spaced apart in the transverse direction 13.
  • a tab distance 25 of the tabs 9 in the transverse direction 13 corresponds approximately to a side surface distance 26 of the side surfaces 14 of the hollow profile, so that the tabs 9 can be alternately connected to the opposite side surfaces 14. In this way, a particularly high level of rigidity is also achieved in the transverse direction 13.
  • Upper flange 1 and lower flange 2 can therefore be easily connected by screws (not shown) to the tabs 9 of the intermediate element 3, which protrude through the tab openings 8 into the interior of the upper flange 1 or lower flange 2, by screwing the screws through corresponding circular screw openings 10 or .
  • Holes are inserted into the side surfaces 14 of the upper chord 1 or lower chord 2 and the tabs 9, after which the screws are screwed into the press-in nuts 7 arranged on the inside. This results in a flat frictional connection between the tabs 9 of the intermediate element 3 and the inside of the upper chords 1 and lower chords 2 formed by hollow profiles.
  • Fig. 2 shows a process step when assembling the support element, whereby tabs 9 of the intermediate element 3 are inserted into the tab openings 8 of the upper flange 1.
  • holes or circular screw openings 10 in the tabs 9 correspond to holes or circular screw openings 10 in side surfaces 14 of the upper flange 1, so that screws are inserted from the outside through these screw openings 10 and screwed into the press-in nuts 7 arranged on the inside can.
  • Both the circular screw openings 10 for inserting screws and the approximately rectangular tab openings 8 for receiving the tabs 9 on the upper chord 1 and lower chord 2 are usually as well as a contour of the Intermediate element 3 and the circular screw openings 10 on the intermediate element 3 are formed by laser cutting.
  • Fig. 3 shows in detail a process step in which the tabs 9 of the intermediate element 3 are inserted into the tab openings 8 on an upper side 21 of the upper flange 1.
  • the tab openings 8 protrude from the top 21 of the upper flange 1 up to side surfaces 14 of the upper flange 1 and are approximately rectangular in shape, with an opening width 15 of the tab openings 8 being slightly larger than a tab width 16 or a thickness of the sheet metal of the intermediate element 3 plus a height 20 of the part of the press-in nut 7 protruding from the sheet metal.
  • An opening length 17 of the tab openings 8 is also only a few millimeters larger than a corresponding tab length 18 of the tab 9, so that the tab 9 can be easily inserted into the tab opening 8, but at the same time only a slight weakening of the material of the upper flange 1 is achieved by introducing the tab opening 8 and lower chord 2 is caused.
  • Fig. 4 shows a carrier 22, which can be used, for example, for a carport, which is formed by a support element according to the invention.
  • the upper chord 1 and lower chord 2 are each screwed to intermediate elements 3, which are also formed by trapezoidal sheets. Screw heads 6 of screws through which the upper chord 1 and lower chord 2 are connected to the intermediate element 3 are arranged on the outside. Screwing is done from the outside, which is why assembly is easy.
  • the construction with a trapezoidal sheet metal between the upper chord 1 and lower chord 2 achieves high rigidity in all directions normal to the longitudinal direction 12.
  • the support element is easy to assemble, especially since the upper chord 1 and lower chord 2 can already be delivered to a construction site with suitable dimensions and corresponding tab openings 8 and screw openings 10, as well as the intermediate element 3, cut, bent and provided with screw openings 10 and press-in nuts 7 These elements simply need to be positioned together and screwed together.
  • Fig. 5 shows a flowchart of a method according to the invention for producing a support element.
  • a sheet metal is provided in a first method step Z1, after which the sheet metal is cut to size by laser cutting in a second method step Z2, tabs 9 also being formed and screw openings 10 being introduced into tabs 9.
  • a trapezoidal sheet metal like in Fig. 1 to 4 shown can be formed.
  • the sheet metal can be galvanized, after which, in a fifth process step, the press-in nuts 7 are pressed in in the area of the screw openings 10, so that screws protruding through the screw openings 10 can be screwed into the press-in nuts 7.
  • upper chord 1 and lower chord 2 are formed, which can be designed, for example, as hollow profiles.
  • corresponding profile tubes are cut and preferably also provided with tab openings 8 on top sides 21 and screw openings 10 on side surfaces 14 by laser welding.
  • the upper chord 1 and the lower chord 2 are then connected by the intermediate element 3 in an assembly process step M.
  • screws are guided through corresponding screw openings 10 on side surfaces 14 of the upper chord 1 and lower chord 2 as well as the tabs 9 of the intermediate element 3 and screwed into the press-in nuts 7 in order to press the tabs 9 onto the side surfaces 14 of the upper chord 1 and lower chord 2.
  • the prefabricated elements upper chord 1, lower chord 2 and intermediate element 3 only require assembly by inserting the tabs 9 into the tab openings 8 and screwing them together, so that assembly can be carried out easily, reliably and with little use of personnel.
