Definitions

  • the invention relates to a frame screw for fastening a door and/or window frame. Furthermore, the invention relates to an arrangement with a frame and with a structure to which the frame can be fastened. The invention also relates to the use of the frame screw and an assembly method for assembling the arrangement.
  • Frame or window frame screws are known from the prior art in order to fasten window frames to masonry.
  • a frame screw with an outer diameter of 7.5 mm is common.
  • a hole is pre-drilled with a diameter of, for example, 6 to 6.5 mm.
  • the frame screw is then usually screwed into the masonry without a dowel to fasten the window frame. If the window frame is to be fastened to a metal container, for example, a hole is drilled into it to accommodate the frame screw.
  • the invention is based on the object of creating a frame screw for fastening a frame to a structure, via which the frame can be assembled in a simple and cost-effective manner.
  • an inexpensive arrangement that is simple in terms of device technology is to be created with a structure and a frame fastened to the structure by means of frame screws.
  • the use for a frame screw should be provided.
  • a frame screw is designed for fastening a door and/or window frame or frame to a structure or a substrate.
  • the frame screw has a screw head, which is followed by a screw shank.
  • the screw shank has a first threaded section and a second threaded section formed at the end of the screw shank.
  • the first thread section can be formed between the screw head and the second thread section.
  • a thread-free shank section is preferably formed between the threaded sections.
  • the threaded sections can have threads that differ from one another.
  • the screw shank has a drill bit designed to screw the frame screw into the structure without a pilot hole. In other words, a hole can be drilled into the structure via the drill bit.
  • a metal carrier structure or a metal carrier is preferably provided as the structure. It has been shown that the frame screw can be used without pre-drilling, even with metal. Alternatively, it would be conceivable to use a wooden structure or a wooden support as the structure. Here, too, it is advantageous to screw in the frame screw directly without pre-drilling. There is an attachment through the frame screw a frame thus simplified in wood or metal construction compared to the prior art.
  • the screw head has a larger diameter than the screw shank, for example, in order to limit the screwing depth of the frame screw. It would also be conceivable for the screw head to have a smaller or the same diameter as/as the screw shank, so that the frame screw can be countersunk into the frame, for example.
  • a thread of the first threaded section is preferably adapted to the material of the door and/or window frame, so that the frame screw engages in a form-fitting manner with a high holding force.
  • a thread of the second threaded section can be adapted to the material of the metal or wooden support, in particular in such a way that it cuts into the metal or wooden support.
  • the threads can be provided that the threads have a different pitch.
  • the gradients can be designed in such a way that, after assembly, the frame screw applies a force to the frame in the direction away from the structure and keeps it at a distance from the structure.
  • an assembly including a frame and structure having a frame opening for the frame.
  • the frame can be inserted into the frame opening.
  • the frame is preferably attached to the structure via a plurality of frame bolts in accordance with one or more of the foregoing aspects.
  • the first threaded portion of each frame bolt is preferably bolted to the frame and the second threaded portion is preferably bolted to the structure.
  • the frame is preferably spaced from the structure by the frame bolts.
  • an arrangement with such a configuration can be produced extremely inexpensively and easily thanks to the frame screws.
  • the frame can be kept at a distance from the structure by the frame screws with the two threaded sections and the unthreaded shank section formed between them for example, subsequently introducing a filling material between the frame and the structure. It is therefore not necessary to provide a filling material before the assembly of the frame, which is then stretched between the frame and the structure, for example via the frame screws.
  • the arrangement according to the invention provides for the frame to be loaded with a force in the direction away from the structure via the frame screws.
  • a metal or wooden support structure or a metal or wooden support can be provided as the structure.
  • the frame screws are preferably introduced from the inside of the frame.
  • the frame can, for example, be partially made of plastic or wood or aluminum, particularly in the area of the frame screws.
  • the first thread of the frame screw is preferably designed in such a way that it does not damage the frame when the frame screw is screwed into it, for example it does not spread. It has been shown that this enables the frame to be secured securely and over a long period of time.
  • the frame preferably has a respective through hole for a respective frame screw.
  • a diameter of the through hole is preferably larger than the outer diameter of the second threaded section, the shank section and the drill bit in order to be able to freely guide these sections through the through hole.
  • An outside diameter of the second threaded section is preferably smaller than an outside diameter of the first threaded section.
  • the unthreaded shank section preferably has an outside diameter that is smaller than the outside diameter of the first threaded section.
  • the maximum outer diameter of the drill bit is preferably smaller than or equal to/like the outer diameter of the second threaded section.
  • the frame opening has, for example, an opening inside which faces the frame and into which the frame screws are screwed.
  • the frame is further preferably spaced from the inside of the opening during assembly, particularly by assembly means that are removed after assembly. It would also be conceivable for the frame to be simply held at a distance by one person during assembly.
  • the frame is preferably spaced apart from the structure in such a way that when the frame screws are installed, the drill bit contacts the inside of the opening and a pilot hole can be drilled. After the pilot hole has been drilled, the second threaded section of the frame screw is screwed into the structure.
  • the drill tip is preferably contacted with the structure before the first threaded section engages in the frame. More preferably, the first threaded portion engages the frame when the second threaded portion engages the structure.
  • a building material in particular a building material that is not pressure-resistant, is preferably introduced between the frame and the structure. This is preferably done after mounting the frame bolts. If the building material is not designed to be pressure-resistant, then practically no force can be applied from the frame to the structure.
  • An insulating material for example, is provided as the building material, in particular for heat and/or sound insulation.
  • a pressure-resistant backing as is often used in the prior art, to relieve the frame screws, can preferably be dispensed with during assembly.
  • the frame screws according to the invention are designed in such a way that they absorb and transmit the necessary fastening forces themselves.
  • the gradients of the threads of the threaded sections of a respective frame screw are preferably designed in such a way that after assembly, the frame is subjected to a force via the respective assembled frame screw in the direction away from the structure and/or is kept at a distance. This means that the frame is not pulled towards the structure via the frame screw. In other words, the frame pushed away from the opening inside of the structure via a respective frame screw and held at a distance and not pulled towards the structure.
  • the frame screw is preferably designed in such a way that it does not break when screwed into metal or when screwed into wood, the latter does not crack or crack.
  • the frame screw has an outside diameter, particularly in the area of the thread, of 7.5 mm. Such a diameter is very common in Germany for other screws, such as so-called concrete screws. Concrete screws are designed to cut into concrete when the concrete is pre-drilled. The thread of the concrete screws is too coarse for metal and wood.
  • the frame screw is preferably designed in such a way that the threaded section ends in front of a structure-side outlet opening of a through-recess or a through-hole and is spaced from it when the frame screw is in the installed state.
  • the distance between the outlet opening and the thread is preferably at least 10%, preferably at least 20%, more preferably at least 30%, more preferably at least 40%, more preferably at least 50% of the length of the passage opening.
  • the invention provides a use of the frame screw according to one or more of the preceding aspects, in which a frame is attached to a structure in such a way that the frame is spaced from the structure and/or is subjected to a force in the direction away from the structure and/or is kept at a distance.
  • the space - in particular the insulating level or the insulating space - between the structure and the frame is free or essentially free during the assembly of the frame screws. It would be conceivable to attach a multifunctional band or something similar to the frame. This can serve as insulating material after assembly.
  • the building material can be attached between the frame and the structure or, for example, the multifunctional tape can be converted into an insulating material.
  • the drilling tip is designed in such a way that from a certain drilling depth the thread of the second threaded section engages in the bore and the frame screw is screwed into the structure. The drilling process is made possible by the thread-free shank area. If a continuous thread is provided for the frame screw, the drilling process would not be feasible with the structure.
  • the thread of the first threaded section under the head is used to fix the frame at a distance from the structure.
  • the structure is, for example, part of a container or a steel girder for hall construction or at least one steel girder. If a container is provided, it can be used to construct buildings such as hospitals. It would also be conceivable to design residential complexes from containers or shipping containers.
  • FIG. 2 shows an assembly method for the arrangement from FIG. 1 in a flowchart
  • FIG. 3 shows a frame screw according to an exemplary embodiment in a side view.
  • FIG. 1 an arrangement 1 is shown.
  • This has a structure 2, which can be part of a building.
  • the arrangement 1 has a frame 4 .
  • This is firmly connected to the structure 2 via frame screws 6, one of which is shown in longitudinal section according to FIG.
  • the frame has a through hole 8 for the frame screw 6 .
  • the frame 4 is fixed to the structure 2 at a distance A via the frame screws 6 .
  • a building material 10 such as an insulating material, can be introduced between the frame 4 and the structure 2. By mounting the frame 4 at a distance A from the structure 2, a distance mounting is formed.
  • the frame screw 6 has a screw head 12. It would also be conceivable for the screw head to have a smaller or the same diameter as/as the screw shank, so that the frame screw can be countersunk into the frame, for example. In the mounted state of the frame screw 6, this rests against the frame 4 and limits the screwing depth.
  • a screw shank 14 adjoins the screw head 12 directly or at a distance. This has a first threaded portion 16 and a second threaded portion 18 at the end, which are spaced apart from one another by a thread-free shank portion 20 .
  • the frame screw 6 has a drill bit 22 at the end, that is to say at its end pointing away from the screw head 12. This is designed in such a way that a drill hole can be drilled into the structure.
  • An outer diameter of the second threaded section 18, the shank section 20 and a maximum outer diameter of the drill bit 22 is smaller than the diameter of the through hole 8 in order to be able to guide these sections of the frame screw 6 through the through hole 8 during assembly.
  • the drill bit 22 together with the second threaded section 18 are designed in such a way that the drill bit 22 drills through a hole during assembly in the structure 2 . From a borehole depth of the borehole determined by the length of the drill bit 22, the second threaded section 18 cuts into the borehole.
  • the sections 16, 18, the screw shank 14 and the drill bit 22 - in particular their lengths - designed such that the threaded sections 16, 18 engage in the structure 2 and the frame 4 substantially simultaneously, in particular at a certain distance between the frame and structure.
  • "essentially" means that the customary assembly and component tolerances should be permitted.
  • an axial length of the threaded section 16 is shorter than a length of the through hole 8 .
  • the through hole 8 is slightly loaded in the area in which the frame screw 6 is unthreaded.
  • the threaded section 16 ends well in front of an exit opening 23 of the through hole 8.
  • the frame 4 in a step 24 is positioned at a distance from the frame opening of the structure 2 .
  • the frame screw 6 with its drilling point 22 and the threaded section 18 is passed through the through hole 8 and brought into contact with the structure 2.
  • step 28 an axial force is applied to the frame screw 6 in the direction of the structure 2 and a torque is applied to the frame screw 6 by means of a corresponding tool that can act on a tool holder of the screw head 12, so that the drill tip 22 penetrates the structure 2 and forms a bore .
  • the second threaded section 18 then engages in the structure 2 and the first threaded section in the frame 4 .
  • the frame screw 6 is then rotated further and screwed into the frame 4 and structure 2 accordingly.
  • FIG. 3 shows the frame screw 6.
  • Alternative head shapes 30, 32 and 34 for the frame screw 6 are shown as examples.

Abstract

L'invention concerne un agencement comprenant un cadre et une structure, lequel agencement a une ouverture de cadre pour recevoir le cadre. Le cadre est relié à la structure par une pluralité de vis de cadre. Les vis de cadre s'étendent par exemple dans un plan commun. En variante, les vis de cadre sont disposées à une distance approximativement parallèle les unes des autres et pointent dans la même direction, en particulier lorsque le cadre est vissé sur l'ouverture de cadre. Le cadre est espacé de la structure. Cela résulte du fait qu'une force est appliquée au cadre par l'intermédiaire des vis de cadre dans une direction s'éloignant de la structure, c'est-à-dire par exemple une force qui est orientée à l'intérieur du cadre. À cet effet, la vis de cadre peut comporter deux parties filetées qui sont espacées l'une de l'autre par une partie tige sans filetage. De plus, la vis de cadre a une pointe de perçage pour former un trou percé par un foret pilote pour que la partie tige côté extrémité soit introduite dans la structure.
