    The present invention relates to a beam structure. Applied known beam structures which are anode and intended to absorb compressive forces in the longitudinal girder of the beam structure in question often have a constant cross-section over the length of the beams. This means that the beams knock close to the center at too high a pressure load and that the material at the beam endpoints is not fully utilized. Exercises, cranes, houses, * ___: el vä such beams are found in bridge construction E _ ïält, etc. In some cases íorsïäïks the beams by building the stages or materials in different designs around the middle of the longitudinal beams for aiï in this way reduce the risk of buckling ~ Examples of such beams are masts, antennas, a larger diameter. These constructions are usually expensive to manufacture and difficult to estimate and control. EXem-e} on such a beam is the spinnaker boom for some sailboats.
    Sometimes there is a desire to have fixing or load-bearing structures that do not change shape during loading. __w Flxtures of various a¿aq in transport and fi Lordon almost always have such demands on him. The fixtures then become extremely heavy and / or need advanced technology to compensate for deformation.
    When transporting aircraft components, it is often required that the components must not be exposed to forces from transport equipment. This places very high demands on robustness in transport fixtures, which in turn meant weight problems.
    The main object of the present invention is thus primarily to provide a beam construction. <1 l o.
    ... In U tion as nl. . the above-mentioned design problems solve a Q] .ction in order to minimize material consumption and weight 1 u ", Ü" É C fl: obtaining strength, enabling controlled constant length of the beam structure at different loads and to lower the manufacturing costs in an efficient and safe way.
    Said object is achieved by means of a beam construction according to the present invention, which is mainly characterized in that several profile beams with a substantially constant cross-section and length are connected to their respective ends with one in each spirit of the shaped beam-common fastening structure so that the said profile beams in the middle of the beam structure are located at greater distances from each other than they are located at both ends of the beam structure.
    The invention is described below as a number of preferred embodiment hexagons with reference to the accompanying drawings, in which Fig. 1 shows a beam structure according to the invention seen across its longitudinal extension, Big 2 shows a beam structure with beam profiling in zigzag pattern.
    Fig. 3 shows an element in operation with in its spirits and empty in perspective, respectively, and Fig. 4 shows a spacer element in effective attenuating position or in perspective obliquely from above.
    The beam construction is intended to be used in truss structures to primarily withstand pressure and tensile forces in the longitudinal direction of the beam. The beam structure can also be used in other cases where forces; _1 are used as support, boom, mast, e acting in the beam direction of the beam.
    The beam structure according to the present invention is comprised of several slightly curved, or slightly straight, partially straight, profiles with a constant cross-section and the same E; in length which are fastened in a circle next to or close to each other (rr: 0 25 a common foot element at each end so that they together form a beam. In the middle of the beam the profiles have a greater distance between them and at the test elements at both ends of the beam a spacer are placed between the profiles and with suitable mutual distances between them extending between the two ends of the beam so that at emerging compressive forces acting towards the center of the beam in the beam longitudinal direction, the profiles strive outwards from the beam's single drum line, but are held together by the spacer elements.
    Due to this design or a beam, almost all material in the belts can work equally along the longitudinal direction of the beam. The number of profiles can vary from three and up. If six or more profiles of even numbers are used, the profiles can be curved in a zigzag pattern along the length of the beam so that every other profile has a mirror-inverted inclination towards adjacent proriles. In the latter case, spacer elements are placed at each point along the longitudinal direction of the beam, where the distance between the profiles is as short as possible.
    By designing the dietane elements so that the distance between the profiles can be increased / decreased dynamically, a length can be achieved and controlled. vi s change of belkene U) The shape of the spacer elements kad changes and is controlled in many ways. Common to the elements, however, is that they work from the center of Ualken.
    Different requirements may exist on the material, but preferably the longitudinal profiles of so-called The pull w DJ 1 - k protiles preferably have a large proportion of carbon fiber in them and they can be cut and tested in the fastening elements with their ends and go right through the distal elements.
    More precisely, the invention relates to a beam construction 1 in which several profile beams 2, 21, 22, 2 "with substantially constant cross-section D and length L are connected to their respective ends RA, 25 with a common fastening element 3, 4 at each end U 1B of the shaped beam structure 1 so that the said profile beams 2 ~ 2 ”in the middle 1C of the beam structure 1 are X located at a greater distance from each other than the distance where they are located at both ends 1A, 1B of the beam structure 1.
    Said profile beams 2-2 "are distributed along the circumference of said two fastening elements 3, 4, and at least some of said profile beams 2 ~ 2" are slightly curved, almost straight or partially straight and that Qistanselement 5 are located between said prosical beams 2 ~ 2 ". At compressive load F in the longitudinal direction 1 of said beam structure 1, compressive forces act towards its center and 2-2 ”strive to bend in the outward direction 7 from the center line 8 of the beam structure but are then held together by said da __) spacer element 5. q ._ * action a is said that a said beam art ya can be used in a drawbar after the longitudinal direction 6 of the slip.
    When six or more Sch a number of prefi-beams 2-One are included in said beam construction 1, the profile beams Q-2 may be curved in a zigzag pattern along the length of the beam structure so that every other profile beam 2-2 ”has a mirror water curvature towards adjacent profile beams 2- 2n. In this case, the spacer elements are located at each point along the longitudinal direction 6 of the beam structure, where the distance between the profile beams D »- is the shortest. fu ”du 1 Lampíigt eat that the spacer elements are designed in and arranged so that the distance between the profile beams 2-2“ is installable to increase or decrease dynamically. The longitudinal profile beams 2 ~ 2 "consist of composite material, preferably carbon fiber material. The spacer member 5 and the ducted fasteners 3, a may consist of the same material or consist of suitable metal »and / or plastic material.
    The function and nature of the invention should have been apparent from the above and from the drawings.
    The invention is of course not limited to the embodiments described above and shown in the accompanying drawings. Modifications are possible, especially with respect to the nature of the various parts, or by the use of equivalent techniques, without departing from the scope of the invention as defined in the claims.
