Definitions

  • the invention relates to a lattice lightweight structure for possibly mobile work, assembly, maintenance scaffolding or platforms and. Like., consisting of tubular vertical and horizontal support elements, which are connected to each other at the grid nodes and, if necessary, from diagonal struts.
  • lattice light-weight structures are used very versatile. They are used in industry, shipyards or the like just as they can also be elements of storage, shelf or parts of railings.
  • Lattice light-weight structures are generally oriented vertically and can be designed either as a single-level structure or as a spatial structure, especially if they are used as work, assembly, maintenance scaffolding or platforms or shelves. Common to all these designs of lattice light-weight structures is that they have vertical support elements and horizontal support elements which are connected to one another at junctions and which may be stiffened by diagonal struts.
  • the known designs are made from pipes, which preferably consist of light metal, but can also be designed as steel pipes.
  • welding In the case of thin-walled tubular support elements which are to be statically loaded to the limit, welding, regardless of whether steel or light metal is used, represents a strength-reducing connection type, because the welding heat causes structural changes which affect the load-bearing capacity, i.e. H. thus resilience of the tubular support elements is reduced.
  • welding has the considerable disadvantage that the knot connections made become unsolvable, i. H. it is no longer possible to convert or repair scaffolding.
  • welding brings thermal stresses into the lattice light-weight structure due to the thermal stress. The result is that the structures must be straightened after welding and, moreover, the welds must be plastered and surface-treated.
  • the invention is based on the object of To design a lightweight structure of the type mentioned at the outset so that it has dismountable knot connections, that is to say it can be dismantled, at the same time has a high load-bearing capacity and avoids the disadvantages of the previous welded connections.
  • the above-mentioned lattice lightweight structure according to the invention is characterized in that vertical and horizontal support elements are connected by means of mountable node connectors, that the node connectors with the vertical and horizontal support elements are in positive engagement by means of projections and recesses on the node connectors and corresponding holes and projections the vertical and horizontal support elements are connected so that the node connectors on the vertical support elements by means of inner, on the horizontal support elements by means of external pressure surfaces additionally in frictional engagement, the node connectors along a plane that coincides with the longitudinal axes of the vertical support elements and horizontal support elements, divided into two half-shells and are held together like pliers by the respective surrounding horizontal support element.
  • the lightweight lattice structure designed according to the invention can be created by means of node connectors which can be easily assembled because they consist of two half-shells. For this reason, the connection can also be released if necessary.
  • the high strength of the node connectors is ensured in that they are connected to the vertical and horizontal support elements on the one hand by positive locking and on the other hand by positive locking.
  • the node connectors are designed so that they are in the area of the vertical support elements enclose them from the outside while they can be pressed into the horizontal support elements.
  • connection areas for the vertical support elements have projections which engage in a form-fitting manner in corresponding holes in the vertical support elements
  • the connection areas for the horizontal support elements have recesses which engage in corresponding corresponding, inwardly projecting projections or elevations of the horizontal support elements.
  • the new node connectors with the correspondingly adapted vertical and horizontal support elements can be installed by first placing the two half-shells around the vertical support element, engaging with the projection or the projections in the hole in the corresponding vertical support element and then pressing the horizontal support element. The forceps-like gripping of the node connector by the horizontal support element has the result that the two half-shells are pressed together with the appropriate force.
  • connection area for the vertical support element which in turn is now additionally non-positively connected to the vertical support element with the pressure surfaces.
  • the horizontal support element is slightly rotated after being pressed on, its inwardly projecting elevation enters the recess of the node connector and also leads to a positive connection in this area.
  • the node connector is now connected to both the vertical support element and the horizontal support element both positively and non-positively; due to the positive connection, it cannot slip or migrate, even under the heaviest loads, unless the projections, which engage in corresponding holes or recesses sheared, i.e. the strength of the material is overcome, and a reliable rattle-free fit is achieved, because the power transmission switches off the game.
  • each half-shell can have a certain play compared to the outer diameter, which makes it easier to assemble and the frictional connection is generated by the inwardly projecting cuffs at the axial ends.
  • the reduction of the pressure contact in the connection area for the horizontal support elements on the narrow longitudinal ribs has the advantage that the pressing of the horizontal support elements onto the node connector is facilitated.
  • the vertical support elements have at least one hole per knot and the knot connectors on at least one half-shell have at least one locking bolt engaging in the hole.
  • the vertical support elements can already be provided with suitable rows of holes in the factory to enable the different lattice constructions.
  • the node connectors can be configured very versatile.
  • a right-angled cross is chosen as the basic concept, a node having two coaxial horizontal support elements being formed on a vertical support element.
  • the basic concept of the node connector is T-shaped, it being possible to connect a single, perpendicularly running horizontal support element to a vertical support element.
  • the connection area for the vertical support element which arise from the pressing of the half-shells onto the vertical support element and can lead to the expansion of the half-shells
  • hook-shaped projections and recesses behind them on each half-shell Projection and one depression each, which are arranged corresponding to each other and interlock when the node connector is installed. In this way, a ring closure is achieved, which is highly resilient to circumferential stresses.
  • the further development according to claim 8 is intended for lattice light-weight structures which are particularly strongly stressed by vibrations and other dynamic influences.
  • An outwardly projecting welding lug can be formed on the stop already provided for the defined position of the front end of the horizontal support element, which makes it possible to spot weld the respective node connectors to the subsequent horizontal support elements.
  • the spot welding at this point is important because it reliably prevents the horizontal support elements from twisting under dynamic influences and thus prevents the positive connection between the horizontal support element and the node connector from opening.
  • the lightweight lattice structure remains mountable, can be dismantled and is not thermally endangered, because a spot weld connection can be carried out without impairing the load-bearing capacity.
  • a point weld connection can either be loosened again with a hammer and chisel or mechanical hammer or with a cutting disc, and the parts of the lattice light-weight structure can be fully reused.
  • a lattice lightweight structure is created in one version, the highest loads in both static and dynamic terms; has grown which is freely variable, d. H. can be disassembled and reassembled in a different form, which guarantees a long service life of the parts and which also ensures quick and clean assembly and disassembly.
  • Grid lightweight structures 1 designed according to the invention consist of vertical support elements 2 and horizontal support elements 3.
  • diagonal struts 4 are additionally provided.
  • the horizontal and vertical support elements 3 and 2 as well as the diagonal struts 4 are made of metal pipes in lattice light-weight structures, steel, but preferably light metal, being used as the material.
  • node connectors 6 are used according to the invention, which are only shown schematically in FIGS. 1 and 2, so that the basic configuration thereof can be seen. Details of the node connector 6 are shown in FIGS. 3 to 7.
  • FIG. 3 shows a node connector 6 in the installed state, wherein it can be seen that the vertical support element 2 is surrounded by the node connector 6 in the area of the node 5 from the outside like a sleeve, while the horizontal support element 3 encloses the node connector 6 from the outside.
  • FIG. 4 shows further details. It shows that the node connector 6 is separated into two half-shells 8 and 9 along a parting plane or joint 7, which coincides with the longitudinal center lines or longitudinal axes of the vertical and horizontal support elements 2 and 3, respectively it can also be seen that in the basic configuration of the T-shaped node connector 6 in FIG. 3, a connection area 10 for the vertical support element and a connection area 11 for the horizontal support element are formed, which intersect at right angles Have system axes.
  • connection area 11 of the node connector 6 is designed such that the horizontal support element can be pressed onto the two half-shells 8 and 9 from the outside up to a defined stop 12. It can be seen that in the outer surface, i. H. of the pressure surface with which the horizontal support element 3 rests on the node connector 6, at least one recess 13 is provided close to the stop 12, in which, according to FIG. 3, a position-adapted, inwardly projecting, molded-in lug 14 engages. In this way, between the horizontal support element 3 and the node connector 6, both non-positive as well as positive engagement due to the pressing on, because the lugs or lugs 14, which are preferably diametrically opposed to one another, snap into the recess 13.
  • connection area 10 for the vertical support element 2 The frictional connection is created by pressing on the horizontal support element 3, because the two half-shells 8 and 9 are pressed together like pliers by the pressing and are thus placed around the vertical support element 2 from the outside like a sleeve.
  • the positive connection is created by two axes running diametrically and at right angles to the system axis of the connection of the horizontal support element 3 by means of so-called latching bolts 15, which are integrally formed on the respective half-shells 8 and 9 and engage in corresponding holes 16 in the wall of the vertical support element 2.
  • the side view of the node connector 6 shows this without horizontal and vertical support elements 3, 2. It can be seen that in the connection area 11 for the horizontal support elements 3, the contact with the enclosing Send horizontal support element 3 is limited to four circumferentially equidistant cross-shaped longitudinal ribs 21 and that the recess 13 is formed by a transverse groove in two diametrically opposed longitudinal ribs and possibly also extends laterally somewhat beyond the area of the longitudinal ribs 21 . Also in the area of the node connector 6, which surrounds the vertical support element 2 and whose system axis runs at right angles to the connection area 11, the pressure contact between the vertical support element and the node connector 6 is reduced to narrow pressure areas 22, which are created according to FIG. 7 by collars 17 projecting slightly inwards will. The collars 17 are located at the axial ends of the connection area 10 and enable the area within these collars 17 to have a certain excess or play with respect to the vertical support element 2, which on the one hand increases the tolerances and on the other hand facilitates assembly.
  • the two half-shells 8 and 9 each have one on the butt joint 7 on the side facing away from the connection area hook-shaped projection 18 and behind it a recess 19, the orientation of which is chosen parallel to the butt joint and also symmetrical to the butt joint.
  • hook-shaped projection 18 and recess 19 engage in one another and close the two half-shells 8 and 9 together in a ring, so that high circumferential stresses can be absorbed under pressure without the risk of the half-shells 8, 9 widening.
  • the hook-shaped connection 18, 19 is unnecessary because the second connection area 11 for a further horizontal strut ensures the ring closure for the connection area 10, which encloses the vertical strut.
  • connection region 11 does not run at a right angle but at an oblique angle to the longitudinal axis of the connection region 10, such that a diagonal strut 4 can be pressed on like a horizontal support element 3.
  • Such diagonal node connectors 6 can be manufactured in a few preferred angular designs, but conventional clamp-like diagonal strut connections can also be used, in which two half-shells are pressed together by screw and nut and secure the connection.
  • such connections are in particular in the case of dynamic loading of a lattice lightweight structure 1 in need of inspection and maintenance.
  • the node connector 6 additionally has a welding nose 20 in the region of the stop 12, which makes it possible to additionally secure the pushed-on horizontal support element 3, if necessary, the diagonal strut 4 by spot welding.
  • This welded connection is irrelevant to the mechanical load-bearing capacity, because it is initially far away from the highly loaded vertical support element 2, emits only a small amount of heat into the environment when it is created, and cannot cause extensive structural changes.
  • such a point weld connection can be easily loosened again by means of a cutting disc or in another way, so that the ability to be assembled and varied is invented appropriately trained lattice lightweight structures 1 is given even when secured by weld point connections.
  • the additional welding point connection in the area of the connection of the horizontal struts 3 or diagonal struts 4 has the advantage that it allows high dynamic loads to be absorbed, because only twisting the horizontal support element 3 or the diagonal strut 4 would make it possible to loosen the knot connection, because only by twisting these elements, the locking lug 14 can emerge from the recess 13 and only when this positive connection would be canceled, there is the possibility that the non-positive connection between the node connector 6 and the respective horizontal support element 3 or the diagonal strut 4 is released.
  • the described design of the lattice light-weight structure is considerably superior, because these known designs are either constructed as clamp connections that have to be held together by screw and nut, or are designed as a hole and plug connection , which either require high precision or only ensure a clattering fit and yet do not absorb high knot forces because the combination of form and frictional engagement, as is achieved in the lattice light-weight structure 1 described, cannot be achieved.
