Definitions

  • the invention relates to a lattice support structure consisting of articulated ver ⁇ connected bars.
  • Lattice structures are used, for example, in structures that must be built only for a temporary period and dismantled for transport again.
  • a disadvantage in particular during transport is that the individual elements of the lattice structures take away a great deal of transport space, since they have large cross sections.
  • the object of the invention is to provide a lattice structure for lattice structures, which can be transported in a narrower space. This is intended to minimize the high transport volume requirement when shipping such girder structures.
  • a lattice support structure which consists of hingedly interconnected bars, designed according to the combination of the features of claim 1 to solve the above problem. Accordingly, a first structure with a small cross-section which extends over its length and represents the transport position can be expanded into a double-pyramidal structure which tapers towards its ends, wherein several of these first structures can be joined together and the first structures joined together mutually connectable by bars to a second final structure, wherein the additional grid bars begin at the vertices of the spread cross-sections.
  • the lattice support structure can be converted from a first reduced cross-sectional size for the transport position into an enlarged cross-sectional size in the working position, wherein the enlarged cross section corresponds to the spread cross section of the articulated structure.
  • the respectively spread cross sections are connected to one another by corresponding bars in the circumference and along the entire structure, so that a rigid lattice support structure results, which has the necessary stability for the working position.
  • the lattice structure can have a triangular or quadrangular cross-section.
  • the cross section is square.
  • hinges which are connected to one another in an articulated manner are preferably present, via which the expandable cross-sections can be expanded or collapsed.
  • the hingedly connected struts may have a core region, which corresponds to the small cross section of the folded first structure. speaks. From the corners of these core areas run articulated struts to the corners of the expandable cross-sections.
  • FIG. 1 shows schematically a first structure of the lattice structure in three stages during erection
  • Figure 2 schematically the spread-first structure and corresponding
  • FIG. 3 shows the erected second structure of the lattice structure
  • FIG. 4 shows the first structure of a lattice structure according to another embodiment variant
  • FIGS. 5 and 5 6 lattice structures in corresponding application examples.
  • FIG. 1 shows in three stations a first structure 10 of a lattice support structure, the structure of the first structure 10 of the lattice support structure being shown in FIG. 1a.
  • FIG. 1 a they have a small cross-section 15, which runs constantly over their length.
  • FIGS. 1b and c show how the middle region of the first structure 10 is spread apart in the respective arrow direction a.
  • Internal braces 18 and 20, which are also connected to one another in an articulated manner, serve for this purpose and can be expanded in the direction of arrow b, for example via a winch 21 indicated here in FIGS. 1a to c.
  • the maximum spread position of the central region is shown in FIG. 1 c, according to which a substantially double-pyramid-frustum-shaped shape results, which corresponds in each case to the - A -
  • the hinged miteinan ⁇ the connected struts in the inner region of the first structure 10 consist of four transverse struts 18 and a central core portion 20, which consists of four square forming struts, this square has the same cross-section auf ⁇ , as the respective end portions of the first Structure.
  • a force in direction c is exerted on the inner strut structure 18, 20, so that the entire articulated latticework is folded together in order to assume approximately the position according to FIG.
  • a plurality of such structures 10 are connected to one another and connected to one another via additional lattice bars 24 and 26, which engage in the area of the spread cross sections.
  • a lattice support structure 5 results for the working position, as shown in FIG.
  • This has a cross-section 22.
  • the minimal cross section, on which the entire structure can be folded, is a similar lattice support structure shown that differs from that according to FIGS. 1 to 3 only in that here the cross section is not square but triangular.
  • a lattice structure 5 is shown that represents the supporting structure of a tower crane here in mounted working position.
  • the support structure 5 is shown in Ar ⁇ beits ein, which forms the boom of a cable excavator here.

Abstract

L'invention concerne une ossature porteuse en treillis, constituée par des barres (12) en treillis mutuellement articulées. L'invention est caractérisée en ce qu'une première structure (10) dotée de faibles sections transversales constantes sur la longueur peut être étendue pour former une structure tronquée en double pyramide s'effilant en direction de ses extrémités. Selon l'invention, plusieurs premières structures peuvent être jointes les unes aux autres et les premières structures ainsi jointes peuvent être reliées entre elles par des barres en treillis (24, 26) pour former une deuxième structure (5), les barres en treillis supplémentaires étant placées en des points d'angle des sections transversales étendues.
