Definitions

  • the invention relates to a support structure for Support flat components with a first Large number of pairs arranged in parallel, in one first level belts, with a second Large number of pairs arranged in parallel, in one second level belts and with connectors, the belt pairs of the second level cross the belt pairs on the first level and the connectors in by crossing pairs of belts formed intersection areas used and with are connected to each adjacent belt.
  • Such a support structure is from DE-A-1 684 602, in which the support structure a variety of rod-shaped elements, such as Wires or rods, which are arranged parallel to each other. At the crossing points are the round belts each with connectors stamped from sheet metal connected with each other. Have the connectors a cross-shaped shape in plan and become by bending the extensions that form the cross shape with the help of special pliers around the rod-shaped Elements bent around so that one relatively firm connection between themselves crossing pairs of rod-shaped elements results.
  • the known support structure is suitable as a metallic construction frame, especially for manufacturing of smaller units such as greenhouses and tents, being due to the proportionate small diameter of the rod-shaped elements high degree of flexibility is guaranteed, so that the known construction sites easily in any Let shapes bend.
  • the Connectors on the rod-shaped elements move to the well-known frame of any Adapt profile or arch shape.
  • FR-A-2 557 900 is a support structure known, with which the basic structure of one Wood to be built building.
  • the load-bearing elements of the basic structure exist from round piles along the to be erected External wall of the building firmly anchored in the floor are.
  • the piles must be level with the ones to be drawn in Floors or ceilings with pairs of belts connected, each consisting of an outside Longitudinal beams and an internal longitudinal beam consist.
  • the longitudinal beams are peeled logs of small diameter, the are flattened on their top.
  • the attachment the longitudinal beam on the piles is also used With the help of through-bolts. Beams, the the substructure for the floor or ceiling boards form and have a rectangular cross section, lie on edge on the inside longitudinal beam on.
  • the well-known wooden construction is suitable especially for prefabricated buildings, since the individual Industrial piles, longitudinal beams and joist beams have it prefabricated and then go to the construction site Basic structure of the building to be erected put together can be.
  • the disadvantage is that the strength of the wooden structure essentially dependent on the anchoring of the piles in the ground is. Only if the piles are properly anchored in the Floor can be in the known wooden construction a certain but low level of shear strength to reach.
  • FR-A-2 501 332 is a support structure known for the bracing of flat elements is provided. Show with this support structure the individual belts at their respective crossing points cutouts facing each other, so that the carrier elements can be plugged into one another. In the assembled state of the support structure are the carrier elements in one Level. Because the support structure is just a very has low shear and torsional stability, it is necessary to use a To be provided with planking.
  • EP-A-0 259 223 discloses a surface element Wood used in the prefabricated construction as wall, floor or Ceiling element can be used.
  • This surface element has two frames formed by straps, between which has a grid. The bars are opposite to the outside frames forming straps rotated 45 degrees and instruct their respective crossing points facing each other Cutouts so that the grille strips are nestable.
  • This well-known surface element shows a good twist and Shear stability, however, is very complex to manufacture.
  • the support structure In that the straps over one essentially have rectangular cross-section and with respect to Plane in which the support structure extends, are arranged upright, the support structure a high bending strength one at right angles to the level of the support structure acting force. Because continues the connectors within the intersection areas essentially about that of the straps formed thickness of the construction and the Belts with their contact surface on the fastening surface the connectors are attached in a rotationally fixed manner leads to a twisting of the support structure inevitably twisting the individual belts. Because considerable forces are required for this are, the support structure next to one high bending strength also a high degree of Torsional stiffness.
  • the support structure also shows a high shear strength because the surface the connectors delimit a volume that the entire free interior of the intersection areas occupies. A change in the crossing angle of the However, belts change the interfaces ahead of this volume. The connectors are however, solid bodies, so that this is not possible. For this reason, the support structure has one unusually high shear strength.
  • the support structure is pronounced durable.
  • the contact surfaces of the straps are on the Attachment surface of the connectors on and thus prevent rolling movements that would otherwise occur cause the lanyards to loosen slowly the straps on the connectors stick together.
  • the connectors fill through the intersecting belt pairs formed intersection area essentially completely off, so that a the largest possible contact between the individual Belts and a connector created is.
  • the two pairs of belts preferably intersect in the essentially rectangular, being between the two Belts of a pair of belts shorter distances are provided as between the respective pairs of belts.
  • the connectors take in the flat Extension of the support structure then only a small proportion, so that the material consumption and thus the dead weight of the support structure is kept low.
  • the distance in the two levels between the pairs of belts and between the two Bending members of a pair of belts provided the same are different with a support structure Stability properties in the longitudinal and transverse directions the distances, for example the bending beam or belt pairs in both planes be designed differently.
  • the Support structure made of strips and squared timbers, the the cheapest main products in lumber production originate, manufactured.
  • the grain direction the last follows their longitudinal extension and the The fiber direction of the connectors runs in substantially perpendicular to that through the ledges educated level.
  • the provision of wood as a manufacturing material gives the support structure a correspondingly low weight.
  • the support structure can be used on one or both sides flat elements, which are not load-bearing Function must come. It is particularly suitable for areas of application where high demands to the bending strength, the torsional rigidity and / or the shear strength can be provided.
