Definitions

  • the invention relates to a scaffold floor assigned to a support bar with support hooks each with a fastening part fastened to the scaffold floor, a support part lying above the support leg of the scaffold-side support bar and a hook part which extends over the upstanding support leg, with a downwardly open suspension mouth being formed between the fastening part, support part and hook part , and wherein each support hook is connected to the supporting structure of the scaffolding floor by inserting fastening parts, welding, gluing and / or riveting or the like.
  • the known solution is a box-like component that runs continuously along the entire profile with a cavity, which has the shape of a rectangular tube and whose lower and upper outer surface have a distance which is the distance between the underside of the sheet metal serving as the tread and corresponds to the stiffening profile created by bending the side flange.
  • the profile with the box-like cavity engages from the front into the interior of the scaffold floor and is firmly connected to it by welding.
  • a longitudinal groove delimited by two legs is provided, which opens downwards and has a hook-like profile, with the aid of which the scaffold floor, for example, on the supporting edge of the U-shaped cross bar is hooked.
  • One leg also forms the outer wall of the cavity.
  • a further longitudinal cavity is provided above the longitudinal groove, which serves to bridge the gap formed between two adjoining scaffolding floors, so that the tread is not interrupted to any significant degree.
  • the upper end wall of this cavity is corrugated on its surface in order to prevent people moving on the scaffolding floor from sliding out.
  • the width of the cavity or the running surface formed by it corresponds approximately to half the distance between the end faces of two successive scaffolding floors.
  • the legs each have a material accumulation in their lower areas, which is slightly larger than the wall thicknesses of the other walls.
  • No diagonal bracing is provided in the cavity above the longitudinal groove. Also in the other, mainly mentioned cavity, no diagonal bracing is provided. These are not necessary with this profile and its use, because the extruded profile part extends over the entire width of the scaffold floor.
  • the invention has for its object to design narrow support hooks on the scaffold floors discussed above in such a way that they are better able to meet the very varied requirements that are placed on them than previous solutions with low weight, ease of manufacture and good load-bearing capacity.
  • the profile of the support hook formed by a short section of an extruded metal profile is a framework-like Stiffening structure with a diagonal web
  • the invention can be used particularly well in the case of support hooks on scaffolding floors which have a frame construction with longitudinal spars which are manufactured separately from the running surface.
  • the shape of the profile of the support hook is chosen so that a framework-like stiffening structure results.
  • the hook profile is made particularly stable by at least one diagonal web. Since the profile of the support hook is designed with a framework-like stiffening structure, the weight can be kept as low as possible and still meet the diverse strength requirements in a particularly simple manner.
  • the support hook consists of a section of an extruded metal profile.
  • the extruded metal profile has more options in areas of the profile in which for some reason it is desirable to provide more metal material than is possible with sheet metal deformation parts.
  • the support hook is formed from an extruded light metal profile.
  • an important improvement according to the invention provides that the part of the support hook projecting the most from the front end of the actual scaffolding floor is reinforced by material accumulation and guidance of supporting ribs in the direction of stable areas of the fastening part and / or the supporting structure of the scaffolding floor.
  • the above-mentioned measure also serves this purpose, namely that the mainly occurring forces are absorbed by a coherent multi-rod construction in the manner of a truss system, both from the normal load when it is placed in the scaffolding and during the impact.
  • Another important aspect of the invention is the design of the outer area of the hook part lying in front of the mouth. This is expediently set back or beveled in relation to the most protruding area of the hook, preferably in accordance with a continuously running line, so that the risk of the hooking mouth being pressed down is considerably reduced when it falls.
  • the design of the hook-in mouth has to take account of the needs for hooking in, and for the good alignment of the scaffold floor, as well as the stability of the hook part.
  • the suspension mouth tapers in the direction of the support surface and in particular that the hook part tapers on both sides towards its insertion tip.
  • the construction is designed in such a way that material accumulations are provided in the most heavily loaded areas of the support hook and jaw limitation
  • it can also be processed well in terms of production technology and, on the other hand, does not hinder the design of the entire profile and the finished support hook.
  • the dimensions given in the claims and the description of the figures are of particular importance for these purposes.
  • the sensible truss concept further contributes to the fact that the support hook can be equipped with a stable anchoring in the supporting structure of the scaffolding floor, which in each case provides a plug-in pin to be inserted into the longitudinal spar of the scaffolding floor, which otherwise makes the different loads and resulting forces more economical Appropriately transfers the construction to the scaffolding floor.
  • Contributing to this are parallel outer walls, which bear against the top wall and bottom wall of the longitudinal spar, as well as vertically running sections of the plug-in pin and, above all, a sensibly placed diagonal bracing, as detailed in the claims and the description of the figures.
  • Such support hooks to be welded to flat end parts of the supporting structure of the scaffold floor can also be provided in the corners of the scaffold floor. Then, however, they are to be equipped with the above-mentioned or similar reinforcements. They can also be attached to a cap which is to be manufactured separately and which forms the end-to-end cohesion and closure of the scaffolding floor, which in turn is to be connected in a manner known per se to the other parts of the scaffolding floor.
  • the support hook has a continuously extending, approximately triangular support part recess and all the boundary walls of the suspension jaw and the support part recess are formed with approximately the same wall thickness and that the flat, vertical contact surface is directly applied to the supporting structure of the scaffolding floor and that a stop lug is formed at the lower end .
  • Fig. 1 only a small part of a scaffold is shown.
  • the stems 20 bear at a distance corresponding to the pitch of the scaffolding system Perforated disks 21 known from one another.
  • a support bolt 22 is fastened between the stems 20 on the perforated disks 21 with the aid of connecting heads 30.
  • the support bar 22 is designed as an upwardly open U-profile.
  • the upper ends of the vertical legs 27.1 and 27.2 of the support bar 22 are designed as support edges 23 for the support hooks 25.1, 25.2 and 35 of the scaffold floor 26.
  • the connection heads 30 are designed in a known manner with slots and plugged onto the perforated disks 21 and secured to them with wedges 34. In this or a similar way, many scaffolding days are realized in one scaffold.
  • This section is only shown to illustrate how the support hooks according to the invention with their additional designs are arranged in the entire framework.
  • the scaffolding floor 26 chosen here as an example has three support hooks on each end face, of which the two outer support hooks 25.1, 25.2 are fastened in the two corners and a differently designed support hook 35 in the middle.
  • the support hook 35 is fastened to a cross member 36 of the support formation 37 of the scaffold floor in a manner shown below, preferably welded on.
  • the cross member 36 is welded in this embodiment between the two longitudinal bars 38.1 and 38.2 of the support structure 37 of the scaffold floor 26 in the region of the corners so that the cut ends 39.1 and 39.2 of the longitudinal bars stay open. This results in a stable frame, possibly provided with transverse stiffeners, not shown, which forms the support formation 37 of the scaffold floor 26. It has - as shown in FIG.
  • - support surfaces 41 which extend over approximately 2/3 of the width of the profiles of the longitudinal spars and in each case reached up to a vertical fold wall 42.
  • edge 43 of a plate 45 is placed.
  • the plate 45 can be formed from heat-resistant glued plywood with an anti-slip layer or another material that is common in scaffolding. It has the running surface 46 of the scaffold floor 26 as the surface. With the aid of rivets 47, the edge 43 is riveted in a manner known per se.
  • the support hook 25 consists of a section of a light metal extruded profile, as can be seen in its overall structure and its details in particular from FIGS. 3 to 5.
  • the cut surfaces are the side surfaces 51.1 and 51.2 of the support hook. These are at a distance 52 from one another, which determines the thickness of the support hook. This distance 52 is selected such that the areas of the side surfaces 51.1 and 51.2 on the fastening part designed as a plug-in pin 50 between the inner wall surface 53 of the longitudinal spar 38.1 and two inner abutment ribs 54.1 and 54.2 provided for guiding the support hook 25 on the lower wall 135 and the upper wall 136 fit properly.
  • Suitable rivets 57 are through the outer wall of the longitudinal spar 38 ... and the insertion pin 50 of the support hook 25 and fastened in the usual manner.
  • through openings 55.1 and 55.2 are provided in the support hook 25, specifically at widely spaced, conveniently located locations, as shown in FIG. 4.
  • the through openings 55.1 and 55.2 are formed in fastening eyes 58.1 and 58.2.
  • the fastening eye 58.2 is formed in the rear, upper corner between the upper wall 56.2 and the rear wall 56.3, the through opening 55.2 being surrounded by approximately the same wall thickness of the extruded light metal.
  • the wall thickness 59 of the lower wall 56.1, upper wall 56.2 and rear wall 56.3 is approximately 4 mm.
  • the fastening eye 58.1 lying further forward and in the region of the lower wall 56.1 is at a distance 61 from the stop surface 60.
  • the stop surface 60 is formed by means of shoulders; namely between the upper fitting surface 62.2 or the lower fitting surface 62.1 and the upper limit 63 of the support part 65 or its lower limit 64, which is advantageously horizontal here, the height of the step being approximately the wall thickness of the longitudinal spar 38.1 or 38.2 of, for example, approximately 2.2 mm.
  • the distance 61 is approximately 15 mm, so that the riveting of the fastening part designed as a plug-in pin 50 in this embodiment of the support hook 25.1 or 25.2 takes place in the longitudinal spar 38 with a large distance from the end and in sufficiently available material and thus one there is a secure connection of the plug-in pin which is already firmly inserted with its mating surfaces in the longitudinal spar for the transmission of large forces.
  • a diagonal web 67 extends obliquely upwards, the exact position of which will be explained in connection with the design of the support part 65.
  • the support part 65 lies outside the longitudinal spar 38.1 or 38.2, that is to say in front of the surface which forms the end 39.1 or 39.2 and on which the stop surface 60 of the support hook 25 is abutted.
  • the support part 65 closes the insertion pin 50 in the lower region with a vertical wall 68. This delimits a continuous lower pin space 69 in the front area with rounded corners.
  • Its outer lower rounded surface 71 emerges from the lower boundary 64 and merges into a vertical, inner jaw wall 72 of the hanging jaw 70.
  • An inner wedge surface 73 adjoins this at the top, which extends to the contact surface 75 of the hook-in jaw 70.
  • the bearing surface 75 has a width 76 which is, for example, 6 mm.
  • the suspension jaw 70 is bounded towards the front in addition to the bearing surface 75 by a wedge surface 74 which has approximately the same steep inclination as the wedge surface 73. It limits the hook part 77 inwards together with an outer, vertical jaw wall 78, which at the bottom fits into one Lead-in slope 79 merges with the lower one Hook end surface 80 connects as a curve.
  • the hook part 77 is bounded on the outside by a hook surface 81 which is inclined inwards towards the scaffolding floor, which extends to approximately the height of the support surface 75 and merges there into a vertical abutment surface 82 of the support part 65. This merges with an upper abutment curve 83 into the upper limit 63.
  • the vertical abutment surface 82 lies at a distance 84 in front of the abutment surface 60. This is the greatest distance from the abutment surface 60, so that the vertical abutment surface 82, if necessary, when the support hook 25 abuts an obstacle or when the scaffolding floor 26 falls vertically onto the support hook 25 hits with the upper rounding 83.
  • the inclination of the hook surface 81 is such that the hook part 77 is not bent inward if possible.
  • a large material accumulation is provided in the area next to the support surface 75 and the upper area of the support part 65 is suitably provided with a support part recess 85.
  • This has a lower, front oblique boundary 86, which extends the upper wall 87 of the diagonal web 67 of the insertion pin 50, and is otherwise bounded by wall surfaces running approximately parallel to the outer surfaces, while its rounded inner wall 89 has a connecting web 90 between the support part 65 and limited to the hanging pin 50.
  • the connecting web 90 has the upper peg space 95 a curved wall surface 96, which continuously merges into the lower boundary surface of the upper wall 56.2.
  • the fastening eye 58.2 protrudes in the corner between the boundary surfaces of the upper wall 56.2 and the rear wall 56.3 into the upper pin space 95.
  • the connecting web 90 merges into a node area 91 which, in addition to the hanging mouth 70, serves to support the forces acting on the supporting part 65 and this in transfers the three webs, namely the vertical wall 68, the diagonal web 67 and the connecting web 90 together with the upper wall 56.2.
  • a support reinforcement 92 In front of this knot area 91, on the outer side of the suspension mouth, there is a support reinforcement 92, which - as can be seen - is limited by the described, oblique lines and is particularly useful for the stability of the support part 65, without the wall thickness differences becoming too great. This enables good production using suitable techniques, particularly in the light metal extrusion process.
  • the distance 84 is preferably 32 mm, while the bearing surface 75 lies by the dimension 93 below the upper limit 63, this dimension 93 preferably being 20 mm, while the hook part 77 is approximately 24 mm long up to its lower tip 80.
  • the total length 94 of the hook with the insertion pin 50 is approximately 92 mm in a preferred embodiment.
  • the diagonal web 67 through the node area in a quasi-straight extension as a diagonally extending one Element merges into the support reinforcement 92 and thus forces exerted on the vertical abutment surface 82 into the lower, rear corner 66 of the insertion pin 50, so that the entire support hook 25 - as can be seen - is designed in a truss-like manner and thus both bending forces and impact forces as a whole receives cheaply and the corresponding forces on the mounting eyes 58.1 and 58.2 with the associated rivets 57 or the stop surface 60, the ends 39.1 and 39.2 or the mating surfaces 62.1 and 62.2 on the longitudinal spar 38.1 or 38.2 transmits perfectly, so that all practical Appropriate design has been found, which allows particularly easy manufacture and assembly, because the extruded profile only has to be cut off, inserted and riveted.
  • the entire support hook 35 is expediently welded all around. It too is formed from a light metal extruded profile which has the shape shown in FIG. 6 and which is formed by simply cutting off its boundary surfaces 111.1 and 111.2.
  • the hanging mouth 107 is surrounded by boundary walls of the same wall thickness, which delimit an approximately triangular support part recess 112 and the hanging mouth 107.
  • the suspension mouth 107 has a shape similar to that of the suspension mouth 70 according to the example described above, but with a simplified edge surface guidance, only the support surface 108 being placed on the support edge 23 at the corresponding support location for the support.
  • the inner mouth wall 115 extends with a lower curve 116 to the vertical wall 117.
  • the outer mouth wall 118 has a lower vertical part 118.1 and an upper part 118.2 which is inclined slightly towards the inside and extends in a straight line above the support wall 119 and into one Final curve 120 merges, to which a horizontal top wall 121 connects, which opens at right angles into the vertical wall 117, so that the support hook 35 is designed with an upper cap part in a simply curved surface up to the connection on the scaffold floor.
  • the wall thickness 125 of all walls is 2.5 mm, for example.
  • the total height is, for example, 42 mm.
  • the remaining dimensions result from the position of the contact surface 108, which results from the position of the corresponding contact surface 75 in the first exemplary embodiment.
  • This support hook 35 can be distributed as an additional auxiliary hook in the middle once or several times over the length, or can also be connected to a corresponding cross member 36 in the corner areas if the stability is appropriate and then take over the main supporting forces. Then its wall thickness is expediently increased and it may be useful to give it a reinforced configuration corresponding to FIG. 4 to support impact forces in the front upper region and also to provide inner ribs.
  • the support hook (25) for scaffolding floors has a fastening part (50), for example in the form of an insertion pin, and a support part (65) with a hanging mouth (70) which is open at the bottom. It is designed as a section of a light metal extrusion profile with a framework-like wall and strut design as well as a support structure with favorable nodes and force transfer areas.
