Definitions

  • the invention relates to a suspended roof structure in which all tension members are used for the actual load-bearing action and which is so stiff due to the spatial arrangement of the support members that a lifting of the roof surface caused by wind suction or a wind-induced swinging of the roof is suppressed.
  • suspended roof constructions are the most economical way to cover large, column-free spans, there have been problems with wind forces since this type of construction was used, since these can achieve multiple values in the pressure and suction areas compared to the dead weight of these very light roof constructions, and thus the hanging construction can cause both local ascent by wind suction and vibrate.
  • the invention has for its object to provide a suspended roof structure over square, oval or round plan, which excludes the aforementioned disadvantages due to its rigidity and is still very light.
  • cross-sectionally weaker link chains with joint points preferably offset by half the chain link length beard chain strands are connected to the chain links of cross-section, cross-sectionally thick frame chains in the articulation points, whereby the dead weight of the entire chain network is entirely absorbed by the weaker cross-section chain structure, but the payload attacking in the articulation points and at the same time crossing points of the chains is aliquot to the cross-sections of the chain links the cross-sectionally weaker and the cross-sectionally thick frame chains are removed.
  • the framework chains consist of links which are connected to one another in an articulated manner, the articulation points of adjacent framework chains being offset from one another, preferably offset by half the link length, and that further framework chains consisting of links having a larger cross section than the links of the first framework chains are provided, whereby the links of the other framework chains are inserted between the hinge points of the weaker cross-section framework chain or at the fastening points on the edge of the structure.
  • the structure will initially be constructed from parallel, or in the case of oval to round building plan, from radially running, light framework chains with a corresponding sag.
  • the chain links of the individual chains are offset from the neighboring chains by half the link length.
  • the one on the links with a smaller cross-section takes over the existing tensile stresses from its own weight and the weight of the heavier two Frame chains, only more payload proportions in relation to their own cross-section to the cross-section of the diagonally running heavier frame chain.
  • the individual cross-sections and cross-sectional relationships can be determined on the basis of the dead weight and the maximum payloads so that an economically designed supporting structure is created. Since the chain links (bars) of the lighter chains always lie above the (higher than) the crossing points of the adjacent, heavier link chain links, they act against lifting the roof by wind suction in connection with the surrounding, diamond-shaped, heavier link chain links such as explosive devices. Strung together and offset by half the length of the link, they fill the entire roof and stiffen it so that it cannot swing open at any point.
  • the smaller vibrations possible due to the material elasticity of the rods can be reduced by inserting spring-damper elements in the light chain links.
  • the light chain links can be divided and held apart in a diamond-shaped manner by means of transverse spring and damper elements.
  • FIG. 3 An example of a suspended roof structure is shown in plan view in FIG. 3.
  • the structure consists of structure chains running parallel to each other between the edges of the structure, e.g. rod-shaped members 2 which are connected to one another via articulation points 3.
  • the articulation points 3 of adjacent structural chains are offset from one another by half the length of the links 2.
  • additional supporting structure chains which consist of e.g. rod-shaped members 4 are provided.
  • the links 4 are inserted between the articulation points 3 or at the edge of the structure between articulation points 3 and attachment points on the edge of the building.
