Definitions

  • This invention relates to a method for producing building elements, and a building element produced with this method.
  • the metal profile may comprise different coupling mechanisms in the edges for coupling to other building elements or constructions.
  • the building elements are made from the profile by first removing most of the metal in the intermediate areas so that the pipes are periodically connected each other by a piece of metal. This recess is made so that the pipes at the edges are connected to the respective intermediate pipes at the same longitudinal, periodic positioned, while the intermediate pipes are connected to each other at longitudinal positions being hallway between the corresponding connection points between the outer pipes and the respective intermediate pipes. This way the intermediate pipes are alternately connected to each other and to the respective outer pipes. After this the profile is fastened in a bench and the outer pipes are drawn away from each other. This method provides a building element as shown in the accompanying figure 1.
  • a disadvantage related to the abovementioned solution is that there are limits for have much the material may be stretched before it loses its strength, especially because the angle at which the intermediate pipes are bent exceeds a certain limit.
  • the angle will normally have a limit at approximately 24 , which in its turn, in combination with other parameters, sets a limit to the width of the building elements.
  • the stability and strength of the building element is given by its width.
  • figure 1 shows a building element made according the known art.
  • Figure 2 shows a corresponding building element made according to the present invention. As is evident from the drawing this solution provides a possibility for a larger angle between the intermediate parts 2 and the outer parts 1.
  • the solution illustrated in figure 2 is made by first fastening a number of coupling devices 3,4 to two parallel, straight intermediate parts 2.
  • the coupling devices are of two types in which the second coupling devices 4 make a coupling between the intermediate parts, and the first coupling devices 3 make a coupling between a intermediate part 2 and an outer part 1.
  • the first coupling devices 3 are in this example positioned in pairs, so that they can connect the respective intermediate parts 2 with the corresponding outer parts 1 at the same positioned in the longitudinal direction.
  • the building element is shown comprising outer parts 1 mounted thereon.
  • the coupling devices are positioned alternately and with equal distances along the intermediate parts, so that one second coupling device 4 is positioned halfway between two pairs of the first coupling devices, each being positioned in a similar way between two second coupling devices 4.
  • the coupling devices are fastened in their positions in any per se known way, which is not to be described here.
  • the coupling devices When the coupling devices have been positioned along the required length of the intermediate parts they are placed in an adapted bench, preferably fastened to the first coupling devices 3, being adapted to pull the pairs of the first coupling devices 3 away from each other.
  • Each of the intermediate parts 2 thus being bent to obtain a zigzag-shape between the first and the second coupling devices 3,4. Normally this operation will also make the building element slightly shorten than the original intermediate parts, which may be foreseen in the production.
  • outer parts 1 may be mounted and fastened in a suitable way.
  • the outer parts are shown in the drawings as elongated profiles, which normally will be the case when producing beams, girders or other building elements.
  • Other solutions may, however, also be contemplated in which the outer elements have other forms, such as other, similar building elements or walls to be provided with a strong and lightweight building elements mounted thereon.
  • Figures 3A to 3D show cross sections of each of the profiles in a preferred embodiment of the invention.
  • Figure 3A shows an example of an outer part 1 comprising traces 9 for connection to the first coupling devices 3 and/or other types of constructions.
  • the profile also comprises a longitudinal opening with protruding edges 5. These may constitute fastening organs for screw or the like, so that the profiles for example may be fastened on a fixed structure.
  • the longitudinal opening also makes the construction lighter.
  • Figure 3B shows the cross section of an intermediate part 2.
  • the intermediate part is drawn with an octagonal outer profile which, when cooperating with a coupling device, may hinder twisting of the intermediate part during the stretching process.
  • the intermediate part is also provided with a through-going opening with fastening organs 5 for screws.
  • Figure 3C shows the first coupling device 3 with a part 6 being formed to be able to cooperate with a corresponding recess in the outer part 1.
  • the shown first coupling device also has an opening 7 for receiving an intermediate part, with a shape corresponding to the outer shape of the intermediate part 2.
  • the second coupling device shown in figure 3D has two openings 8 for receiving the intermediate parts 2. These openings are also adapted to the outer shape of the intermediate parts.
  • One especially interesting one comprises only one intermediate part with one type of coupling devices positioned with equal distances along the intermediate part, possible alternatively oriented different ways.
  • the intermediate part will make a zigzag-shape between the connection point to the outer parts.
  • Other variants with three or more intermediate parts are also possible.
  • the different parts of the building elements may be shaped in different types of materials, for example aluminum. Hardening and other characteristics may be chosen according to the element which is to be produced, but because a relatively large degree of deformation in the intermediate parts is required they will preferably be made slightly softer than the coupling devices. For the strength of the finished element it may, however, be advantageous if the coupling devices are somewhat deformed, so that the intermediate parts are sufficiently fastened to the coupling devices.
