Definitions

  • Such scaffolds are usually used with stems made of steel tubes and with elongated scaffolding elements made of steel tubes or other profile parts made of steel.
  • scaffolds with tubes and / or elongated scaffolding elements made of light metal have also been used, but with many other honing details. This is mainly due to the fact that there are high requirements for the loads on the connections of a module frame, which are difficult or impossible to achieve with light metals and only in certain material combinations and design details.
  • the invention has for its object to provide a scaffold of the above type, which has optimized design in terms of weight, load capacity and absorption, support and transmission of the forces in the connecting devices.
  • connection heads are reduced to the structures which are absolutely necessary for the internal transmission of the forces and a sensible introduction, support and transmission of the occurring forces into the other components. Accordingly, one makes a sensible transition to the diameters or heights of the elongated scaffold elements in the case of relatively long system support surfaces, but above all the outer boundaries of the system end faces to the central axis are set differently because the wedge to be driven in from above indicates its point of attack or its line of attack or its area of attack in the perforated disc is not in the middle, but is offset upwards.
  • the design of the wedge opening walls and the area around the slot ensures on the one hand that the wedge can be kept easily captive and that the cross sections required there are available for power transmission, on the other hand also sufficient material in the areas immediately adjacent to the perforated disks for securing against lateral Tipping is present.
  • connection heads While the attachment of connection heads by pressing and pressing areas into recesses is known from DE-PS 24 49 124, this was hardly used in practice in steel because welded connections are more useful. However, this connection is particularly suitable for connecting light metal pipes or other light metal profiles with steel connection heads and enables a weight-saving, secure connection between the components of different materials.
  • connection heads and wedges which is probably the cheapest solution, because it allows the best fastening conditions with few light parts and is safe while using the least material Force application of forces of different directions and without risk of loosening of the wedges and the like. What is not so feasible in other connection designs with cups, double cups or in welded tabs into which connecting elements and / or wedges are inserted from above.
  • the perforated discs it is also important to adapt the perforated discs to the conditions of the light metal.
  • the dimensions of the existing designs must be observed where there are contact surfaces or slots.
  • the perforated disks made of light metal which are inherently low in strength, can only be designed in a few places so that they allow greater forces to be transmitted. Accordingly, dimensions are also important for the invention, because the previous disks and the associated elements were designed so that a disk outer diameter of 122 mm and a disk thickness of 9 mm for a steel disk proved to be optimal.
  • the thickness of the perforated disks can be provided with 10 mm and the outer diameter of the perforated disks with 124 mm while reducing the play. If the radius is increased by only 1 mm and the thickness is increased by only 1 mm, an approximately 33% increase in the load-bearing capacity is achieved at the critical points with regard to the combined stress due to shearing and bending, and in particularly stressed areas between the outer corner of the hole and the outer circumference and in the area of the center of the outer partial ring web of the large perforations of the perforated disks.
  • a further embodiment of the invention which is in the form of pipes or otherwise with a ring cross section designed elongated scaffolding parts with corresponding reinforcements at least on the underside, for example in the manner of a T-profile or a box profile. So on the one hand you have the option of choosing standard connections, for example with a round tube cross-section, but on the other hand you can increase the bending strength as desired and still use inexpensive extruded profiles.
  • the platform elements to be connected will be equipped with large hooking claws that reach over the horizontal bolts and that are designed with automatically locking elements.
  • a reinforced, elongated scaffold part with a tubular ring cross-section and downwardly projecting T-profile according to claim 5 is particularly expedient because it is easy to produce and results in clear static conditions and clear strength relationships and because it also allows the conventional large claws to be attached with securing fingers. Further details, configurations, features and advantages of the invention also result from the following description part dealt with on the basis of the drawings and, if appropriate, further claim features.
  • the stem 1 has four stems 20. They are identified by sub-numbers 20.1, 20.2, 20.3, 20.4 to distinguish them.
  • the stems 20 are supported on height-adjustable casters 21, which are also designated with differentiation decimal places.
  • the stems can consist of a plurality of tubes which can be plugged onto one another and have 23 perforated disks 22 at a suitable distance, which are provided with openings 24 in a known manner and as can be seen from the drawings.
  • the wedges 26 of the connection heads 25 of the various scaffolding elements 27 to be connected to the stems 20 grip through them.
  • there are horizontal bars 27.1 and diagonal bars 27.2 which can be of a suitable diagonal or diagonal in space.
  • scaffold floors 28 form the upper platform or are provided as intermediate floors for the ascent with the aid of the ladders 29 in a conventional manner. They have claws 28.1, which grip over the horizontal bolts in the usual way and are provided with safety fingers that automatically reach underneath.
  • the stems 20 are made of light metal with a wall thickness 31 of 4 mm and an outer diameter 32 of 48.3 mm, that is to say a radius 47 of approximately 24 mm, as is customary for such modular scaffolding and can therefore also be used with scaffolding elements such as connecting couplings and Like. Be used from standard scaffolding systems.
  • the perforated disks 22 are made of light metal and are welded to the round tubes of the stems 20 by means of the two weld seams 33 in the appropriate spacing 23. They have an outer diameter 34 of 124 mm and a thickness 35 of 10 mm.
  • the distance 42 of the wedge contact wall 36 from the stem and disc center 37 is 50 mm. This is the radius 39 the cylindrical wedge wall sections 38 of the larger openings 24.2 for the connection of the diagonal bars the same. Compared to conventional perforated discs, the radius is increased by 1 mm and the thickness by 1 mm.
  • Terminal heads 25 and 105 are generally standard in configuration, which is also required to use them in a modular system.
  • the side boundaries 46 as can be seen from FIGS. 2 and 7, are designed in a wedge-like manner towards the stem and disk center 37, so that there are eight connection options lying directly next to one another.
  • the system support surfaces 50 are, as can be seen from FIGS. 2 and 7, with the radius 47 of the outer wall of the stem 20 of 24 mm concavely curved and their edge regions 48 merge with curves into the side boundaries 46, so that there are no sharp-edged impressions in the Pipe wall gives what is particularly important for the soft light metal material.
  • Usual horizontal slots 49 with a height of 12 mm are provided. These merge into the system support surfaces 50 with large corner curves 51.
  • the contact support surfaces 50 are interrupted and divided into two contact areas 50.1 and 50.2, which come to rest on both sides of the respective perforated disc 22 on the respective stem 20.
  • These two contact areas 50.1 and 50.2 have openings 52 which extend to the wedge receiving space formed by the wedge openings 53.1 and 53.2, so that the contact support surfaces 50 are reduced to the extent necessary for the support of the forces of curved rectangular ring surfaces, in which the position of the resultant Force application surfaces is roughly indicated by arrows 55.1 and 55.2.
  • the height of the contact face sections is - as can be seen from FIG. 8 - different.
  • the outer lower boundary 56.1 lies down from the horizontal center plane 57 of the slot 49 by the distance 58.1, while the outer boundary 56.2 lies upwards from the horizontal center plane 57 by the distance 58.2.
  • the dimension 58.1 is preferably 30 mm and the dimension 58.2 is preferably 36 mm, so that there is a total height 58.3 of 66 mm, the center of which is offset by 3 mm from the horizontal center plane 57, which means approximately the same distances 61 from FIG. 3 visible wedge contact area 60 result, so that the moments applied act with the same lever arms and thus with approximately the same supporting forces on the pipe and the connection head.
  • the rear contact face 63 is expediently delimited by a circle which corresponds to the outside diameter of the tubes of the scaffolding system, here with a diameter of approximately 48 mm.
  • the side boundary lines 46 run in a straight wedge shape up to the contact face 63
  • the upper boundary line 64.2 and the lower boundary line 64.1 in the exemplary embodiment are designed to be slightly curved, so that the head generally gradually increases to the diameter or the height of the elongated scaffolding element to be connected reduced.
  • the lower boundary line 64.1 is somewhat concave.
  • the upper boundary line 64.2 is curved somewhat convexly to accommodate an approximately straight wedge to be placed parallel to the pipe and secured against loss.
  • the wedge openings 53 Perpendicular to the slot 49 extend through the connection head 25, the wedge openings 53, which have a width 67 up to the retaining ribs 66, which is slightly larger than the transverse extension of the rivet 68 of the wedge 26, so that the wedge can be moved up and down without problems .
  • the wedge opening 53.1 has only a width 69 which is greater than the thickness 71 of the wedge, however, is less than the length of the rivet 68, so that it serves to prevent it from falling out, and on the other hand allows the wedge to be pulled up via the slot 49, the end 26.2 of the wedge, as can be seen in FIG. 3, being provided with an edge recess 72 to place the wedge for transport approximately parallel to the scaffolding element.
  • a recess 73 is formed in the top of the head.
  • small beads can be seen on the outside, which are designed in such a way that there are sufficient cross sections for the power transmission, but no unnecessary, weight-increasing material accumulations. In this case, depressions can be formed between these beads and the legs 65.
  • the heads for the connection of the scaffold elements are the same for scaffold elements to be connected in the axial direction as well as at an angle, with respect to the parts described above.
  • connection heads 25 are provided on the connection heads 25, as can be seen in FIGS. 3 to 9, which have an essentially or almost cylindrical attachment surface 76 on the outside, to which this is shown here, for example cylindrical tube 77 of a horizontal bar 27 is attached.
  • the length 78 of the extensions 75 depends on the elements to be clipped on.
  • the extensions 75 have an inner cavity 79 which, as can be seen from FIGS. 6 to 8, is somewhat conical with a diameter which decreases with respect to the front connection head. Its end region 80 merges with the partial spherical shape according to the radius 82 into the reinforced transition region 81 of the connection head, the inner cavity 79 opening towards the slot 49. This is a transition area 81 with a sufficient overall cross section for the transfer of forces at the maximum stressed point.
  • Fastening perforations 83 extend transversely through the extensions 75.
  • dome-like deformation regions 84 of the attached and pressed-on tube 77 are pressed in to secure them against rotation and against pulling off.
  • a secure connection between an extruded aluminum tube 77 and a cast steel connection head 25 for permanent use of a scaffold according to the invention is possible and thus an optimal design with low weight is created, the transfer and support of the forces occurring with the least material and the highest possible level of safety is guaranteed, taking into account the conditions of the favorable connection system with the perforated disks and penetrating wedges and on both sides of the perforated disks, connection structures supported directly on the tube, so that light metal extrusions are used for the elongated components, which have the largest material volume can be used while steel parts of small cross-section and thus low volume and thus low weight at the highly stressed points while optimizing the shape.
  • panes can only be economically attached to the pipes by welding and accordingly light metal perforated panes are to be used, the dimensions of which, however, were selected within the framework of the modular system in such a way that they meet the loads for tower scaffolds over 12 m high and the like if extremely high total scaffolding loads, which are rare in practice, are not desired.
  • the elongated scaffolding elements 27, in particular the horizontal bars, directly support the claws 28.1 of the scaffolding floors in the construction provided in FIG. 1.
  • considerable bending stresses are applied to them, which under certain circumstances can no longer be absorbed with certainty by a thin-walled light metal tube in the long term and with slight overloads.
  • a web 91 and a flange 92 in the center as a lower flange, which at the ends 93 are designed, for example, at 45 °.
  • the total height can be, for example, 110 mm with a leg width of approximately 42 mm and a tube outer diameter of 42.3 mm and a tube wall thickness of 2.8 mm.
  • the securing fingers of the claws 28.1 can then engage the tube 77 in the region below the horizontal center plane without being hindered by the web 91, so that automatic lifting safeguards can be used.
  • a box-like reinforcement profile with two webs 91.1, 91.2 - only indicated by dashed lines - and a continuous lower flange 92 can be provided.
  • connection heads with pivots which are fastened to the disks with wedges in a conventional manner in accordance with the respective free possibilities and the diagonal bars have tabs.
  • Such basically known connections are dealt with in an embodiment according to the invention for a light metal-steel construction in FIGS. 16 to 20.
  • Terminal heads 105 which are designed in the front part, as explained above, are fastened with wedges 26. They have flat, circular end faces 103 and pivots 106 fastened in the central axis 57/107.
  • a contact head 106.1 of the pivot 106 lies in the receiving recess 105.1.

Openings 113 are formed therein, in which the tube 117 is fastened in the same way as the tube 77 on the extension 75 with the aid of the fastening openings 83.
  • the front, free connection area 120 is deformed into an essentially flat rectangular flap with a height 118 of approximately 15 mm and has a central receiving recess 119 which, by further pressing in, as shown in FIGS. 19 can be seen, is formed, as is known per se for diagonal rod tubes made of steel.
