Definitions

  • the invention relates to a protective and / or work frame for overhead line construction.
  • JP H03 156065 A relates to the provision of a three-dimensional scaffolding structure which can be erected by a plurality of rod elements connected to one another, the scaffolding structure having a gate recess, the post bars of which vertically delimiting the gate recess are stabilized by a horizontally extending support element attached to it.
  • 5,390,463 relates to a modular framework system, comprising prefabricated cuboid modules, in particular for the design of a protective and / or work scaffold with at least two tower elements and at least one top chord carried by the tower elements, the tower elements having similar cuboid modules arranged one above the other and connected to one another and the top chord arranged next to one another and having similar cuboid modules connected to one another.
  • the cuboid modules can have four parallel round bars running in the longitudinal direction and four of the round bars at the ends, either diagonally or parallel to the sides of the cuboid modules, box-shaped cross bars.
  • the disclosure document JP 2004 270403 A relates to a protective scaffolding installation, comprising at least two tower elements and at least one upper chord carried by the tower elements, the tower elements having cuboid modules arranged one above the other and connected to one another and the upper chord comprising cuboid modules arranged next to one another and connected to one another, the connection between a tower element and the upper chord by means of one of these two common cube-shaped adapter module takes place and the tower elements are supported by foundation elements.
  • a large number of such frame elements can be used to design a support structure, for example to set up exhibition stands and shelves, and are used there in the same way for horizontal connections as well as for vertical constructions, the frame element being a simple suspension of parts in the parallel elongated elements when mounted vertically of the stiffening element.
  • a portal is assembled by using a plurality of such frame elements and associated node parts, comprising two tower elements and an upper chord carried by the tower elements, the tower elements having similar, cuboidal modules arranged one above the other and connected to one another, composed of the frame, and the upper chord Identical, cuboidal modules composed of the frame and arranged next to one another and connected to one another, and wherein the connection between a tower element and the upper chord is made by means of a cube-shaped adapter module common to these two.
  • the disclosure document US 2013/2917477 A1 relates to the connection of a plurality of structural supports with respective extension elements, which are connected via a connector block.
  • the structural supports and the respectively assigned expansion elements have connectors which are designed as brackets provided with holes.
  • a first and second structural layer are first built up by at least each respective connection of four horizontal beams with four connecting elements and two cover elements. Then one of the structural layers is raised relative to the other and both vertically spaced structural layers are attached to respective connecting elements by means of vertical supports connected. The interconnected structural layers are then raised together, and subsequently connected to a further structural layer assembled as described by means of vertical beams, this step being repeated until the desired framework structure is achieved.
  • the erection of the scaffolding according to the invention can be done in such a way that the upper chord composed of the cuboid modules and the adapter modules is first mounted on the floor, which is then raised by means of at least one lifting device by a distance, which the arrangement in each case one for the Tower elements provided module allows in a position in which it is connected to the top belt by fastening to the respective adapter module provided.
  • This can be done on the floor using, for example, small assembly scaffolding whose height does not need to exceed the length of a cuboid module.
  • the number of tower elements will depend on the length of the upper chord and possibly also on the load-bearing capacity of the at least one lifting element to be used. The latter also applies to the maximum height of the scaffolding to be erected, whereby its stability can be secured by guy ropes if necessary.
  • the top chord 12 and tower elements 14 are essentially composed of cuboid modules 18, one of which is shown in FIG Figure 3 is shown.
  • Each of the modules is designed as a framework and provided with four parallel rods 20 running in the longitudinal direction, which are connected to one another at the respective end of the cuboid by four transverse rods.
  • the longitudinal rods 20 have a significantly greater length than the transverse rods, so that in the exemplary embodiment shown in the drawings, a diagonal strut 28 is attached to at least two opposite sides 24, 26 of the module.
  • struts 28 are provided on each of the two sides, each extending from one end of the module and meeting in a plane dividing the module in half and being attached there to the opposite longitudinal rod.
  • another diagonal strut running in this plane is provided in the strut 30.
  • the number and arrangement of these struts depends on the particular circumstances, in particular also on the length of the modules, which can generally be about two meters, for example.
  • the connection between the upper chord 12 and the respective tower element 14 is made using an adapter module 32, which is composed of rods 34 of the same length and thus has the shape of a cube ( Figure 4 ).
  • the surfaces of the cube correspond in terms of dimensions and shape to the end faces 27 of the cuboid modules. Because at least the cuboid modules of the top chord and tower elements coincide with regard to their cross-sectional shape and size, both the modules 18 of the upper chord 12 adjoining the respective adapter module 32 and the corresponding modules of the tower elements 14 can thus be connected to the adapter module, as shown in particular from Figure 2 can be seen.
  • the adapter module 32 is connected to a cuboid module 18 on two of its opposite surfaces.
  • the uppermost cuboid module for the respective tower element 14 is attached to a further, to the two aforementioned surfaces of the vertical surface that delimits the adapter module on the underside.
  • fastening means that are designed as tabs.
  • the arrangement of the cuboid modules is such that alternating single tabs 36 and double tabs 38 are provided on each end face at the four corners thereof, the double tabs being arranged parallel to one another and at a distance from one another, such that between the two tabs of a double tab 38 of a module of a single tab of an adjacent module can be inserted.
  • All brackets are provided with a hole, the holes of all brackets being aligned with one another in the connection position so that they can receive a screw bolt or other suitable connecting means in order to connect the brackets of both adjacent modules and thus the modules to one another connect to.
  • the two tower elements 14 are each on a foundation element 41 ( Figure 5 ), which consists of two longitudinal beams, for example double-T beams 42 and some cross beams 44 connecting these longitudinal beams and is arranged and optionally anchored on the floor receiving the scaffolding.
  • the foundation elements 41 can, depending on the nature of the ground on which they are placed, be provided with extensions or the like on the underside, which provide a safeguard against displacement that may be required.
  • the cross members 44 located in the middle are also provided with single straps 36 and double straps 38 corresponding to the attachment of the straps to the cuboid module in such a way that the lower end of the respective lowermost module of the tower element is connected to the foundation element 41 in the manner described can be.
  • the frame shown is provided along the top chord with a work platform 46 to which a railing 48 is assigned.
  • the modules of the upper chord and the adapter modules are provided with corresponding additional components which, when the modules are installed, complement each other to form this work platform in the railing (s).
  • the right tower element of the scaffolding according to Figure 1c is provided with a vertical climb with back protection and resting platforms.
  • the modules of this tower element are provided with corresponding components that complement each other to the climbing gear, etc.
  • the scaffolding according to Figure 1a is secured with guy ropes 54 due to its greater height.
  • the framework according to the invention can also have more than two tower elements.
