Definitions

  • the invention relates to a holder for railings on scaffolding with a wedge box and a pivotable, captive wedge supported therein.
  • Railings on scaffolding are designed according to DE-PS 27 57 189 with tabs that protrude downwards at their ends and can be inserted into wedge boxes.
  • captive wedges are provided with suitable wedge arrangements of sufficient insertion length, which allow either one tab or two tabs to be fixed with the same wedge.
  • This proven arrangement provides suitable support surfaces and separate captive devices.
  • the wedges During assembly, it must be ensured that the wedges have released the insertion space and are in the only possible hanging position with them. If this is not observed, the assembly person on the u. U. high scaffold without side protection go to the appropriate place and swing the wedge into the hanging position. This is annoying and not dangerous in certain situations.
  • the wedges are relatively far into the working and passage space of the scaffold due to their two slots.
  • the wedge must always be held in a raised position by hand and the person assembling or dismantling the scaffold has only one hand free for the railing.
  • large parts of the railings can only be installed by two people.
  • the person With one-person assembly, the person must be able to assess the correct position of the wedge in order to bring the wedge into the correct position on each individual box beforehand. Such requirements are a hindrance to practical operation. Swiveling the wedge on high scaffolding without guardrail is not without safety risk.
  • the wedge is supported on one Simple bolts, also with threads, lead to very fast, large wear and to undefined wedge ratios.
  • the pressing forces applied by the wedge to the straps, which fix these, are supported directly on the wall of the handle and thus offer unfavorable support conditions.
  • the tabs of the side walls of the insertion space which are to be welded individually to the support, must be of very stable design and aligned very precisely in the correct position so that a reasonably usable arrangement is produced. Nevertheless, there are high loads and voltage peaks in the corners.
  • the patent deals with a group of inventions which are interconnected in such a way that they implement a single general inventive idea which consists in holding, fixing and supporting devices for the wedge in railing mounts of the type mentioned at the beginning and to design associated elements so that the manufacture and use are improved by improving and optimizing the design of the wedge and the support of the forces that occur.
  • the invention has for its object to provide a bracket for railings on scaffolding of the type mentioned with a support and wedge arrangement that allows the railing to be hung without touching the wedge in any position of the wedge and, if necessary, additional measures to reduce Wear and to increase stability and simple and safe manufacture are provided.
  • the first part of the invention group is essentially based on the task of finding an improved wedge design.
  • the wedge can hang in any end position and it is possible, without touching it, to insert either one tab or two tabs simultaneously or two tabs one after the other .
  • the wedge can then be brought into the clamping position without hindrance in order to be fixed there.
  • the tabs can be lifted without jamming thanks to the clever choice of its shape.
  • the measures are also incredibly simple and ensure considerable simplification of assembly without any additional manufacturing effort.
  • the safety during assembly and disassembly of the railing is considerably improved in that the assembly person does not have to go to a place for hanging the railing without securing through a railing in order to check the wedge for its hanging position and, if necessary, in a suitable position bring to. Because there is no jamming during disassembly and assembly, only one person is required for this work.
  • the hanging wedge regardless of whether a tab is already inserted or not, is automatically moved into a partially swiveled-up position when inserted, without the actual wedge effect occurring.
  • a person can either insert only one railing strap or, after inserting a railing strap, insert the second railing strap without the need for a hand to hold the wedge in place.
  • the wedge is then moved from its partially swiveled-up position to the securing position and, if necessary, hammered down. After loosening it can be like other wedges hang down and disassembly is no longer hindered by the wedge and can be carried out by one person at a time.
  • the length of the elongated hole and the pressure outer surface and the distance from the same to the reference line of the elongated hole are coordinated such that the wedge has such a stroke in both possible positions that it you can choose to secure one or two tabs, you do not need to bring the wedge into a certain position during assembly and only have to swing it up to secure it.
  • the scaffold 30 shown schematically for example in FIG. 1 has vertical stems 31.1 and 31.2 which are connected to frames by transverse horizontal beams 32.
  • Two wedge boxes 33 are fastened to the inside of the frame at a suitable, predetermined height on the stems 31. 1 located outside the building, as is usual with such scaffolding. These serve to fix the horizontal railing rods 34.
  • the railing rods 34 have bent and flattened railing straps 35 at their ends in a known manner. These have a width 36 of approximately 33 mm and a thickness 37 of approximately 6 mm. They extend from the support surfaces 38 down the length 39 to the end edge 40 cut off in the corners.
  • the railing tabs 35 are inserted in a known manner into insertion spaces 41 of the wedge boxes 33 which are open upwards and here downwards, for example.
  • the insertion spaces 41 are delimited by side walls 42.1 and 42.2.
  • the side walls 42.1 and 42.2 are connected in the area of the stem wall 43 by a web 44 formed in one piece with them. This web 44 is designed on its pipe contact surface 45 to match the cylinder of the cylindrical tubular handle.
  • FIGS. 3 and 4. 3 is designed as a bent sheet steel part.
  • the web 44 has a central contact area 46 which is straight.
  • the embodiment variant according to FIG. 4 differs from the one shown above only in that it is a light metal extrusion profile in which the inner contact surface 55 of the web 44 is designed in the form of a part circle. All other elements are essentially the same. The wedge box designs in the two variants are therefore treated together.
  • a wedge bracket 60 is formed opposite the tab system 50. This has a slot 61 lying radially to the stem cross section, the width 62 of which is larger than the outer width 63 of the wave crests 64 of the corrugated wedge 65 by a sufficient clearance, as shown in FIGS. 3 illustrate. Due to the corrugated design of the wedge shown in FIG. 2, dirt is easily removed and good sliding through the slot is achieved.
  • the two slot walls 66.1 and 66.2 serve to limit the slot 61. These are arranged parallel to the side walls 42.1 and 42.2 offset inwards and connected to the side walls 42.1 and 42.2 via connecting legs 67.1 and 67.2, which are at right angles between them and limit the insertion space 41 to the outside. As can be seen, the slot 61 is open at the top and bottom and towards the insertion space 41 and towards the outside. In this way, the wedge 65 can be pivoted freely with suitable formation of aa.
  • a bolt 70 penetrating the slotted walls 66.1 and 66.2 which can be designed in many ways, as described below.
  • the bolt 70 extends through the elongated hole 75 of the wedge 65. Together they provide both the support of the wedge forces and the securing against loss.
  • the wedge 65 of FIGS. 5 to 12 is an asymmetrical outer contour with a lifting cam 97 and the wedge of FIGS. 13 to 17 is a symmetrical wedge with two lifting cams 97.1 and 97.2. Both forms of wedge have only one slot 75 of length 76 and width 77, which penetrates the flat wedge.
  • the wedge suitably consists of stamped sheet steel or, if applicable, light metal sheet or reinforced plastic depending on the design of the other scaffolding and the conditions of use.
  • Each wedge has an outer pressure surface 78. This extends at a wedge angle 79 to the reference line 80 of the elongated hole 75.
  • the outer pressure surface 78 is straight.
  • the length 81 of the rectilinear pressure outer surface 78 and the length 76 of the elongated hole 75 and the wedge angle 79 are matched to one another in accordance with an important feature of the invention such that either a railing bracket 35 or two railing brackets 35 can be clamped one on top of the other with the same pressing outer surface 78 .
  • the reference line 80 runs through the axis of rotation or pivot axis of the wedge formed by the axis 90 of the bolt 70 and is in the simple wedge 65 to the longitudinal central axis of the elongated hole 75 by the amount of the indentation 121 in relation to the distant surface line of the bolt in the direction of the contact pressure Outer surface 78 offset, as illustrated in FIGS. 5 and 9.
  • both lines coincide to form a reference line 80.
  • the other long outer contour surface 82 is guided parallel to the reference line 80 of the elongated hole 75 at a distance 83, which is explained in more detail below.
  • the connecting contour 85 running in the narrower area 84 of the wedge 65 from the pressure outer surface 78 to the outer contour surface 82 is designed in its part 85.1 adjacent to the outer contour surface 82 in a quarter circle with the radius 87. This corresponds to the distance 83.
  • the remaining area 85.2 is designed to increase continuously up to the transition corner 88 to the pressure outer surface 78.
  • the distance 89 (FIG. 3) from the bracket system 50 to the axis 90 of the bolt 70 is coordinated with the thickness 37 of the railing brackets 35 and the distance 83 or the radius 87 such that when two railing brackets 35 are inserted, as in FIG 7 illustrates - with the wedge 65 hanging down and supported on the end 91 of the elongated hole 75, which lies in the region of the narrow side 84 of the wedge 65, there is no contact.
  • the distance 89 is therefore greater than the sum of two thicknesses 37 and a distance 83 or radius 87, so that there remains an insertion play 92 and the railing straps can be inserted either as a single strap or both at the same time or in succession without wedge contact and no obstruction by the wedge takes place or the wedge 65 can slip through with the outer contour surface without clamping the railing tabs 35.
  • the distance 89 is dimensioned such that in the clamped position of the wedge 65 (FIGS. 6 and 9) either one or two railing tabs 35 can be securely clamped by the pressure outer surface 78 taking into account their length 81 and the wedge angle 79.
  • the outer contour 95 of the wedge 65 in the region of the wider side 96 of the wedge is designed with a lifting cam 97 in such a way that the pressing outer surface 78 is increased by an amount which can be seen from the drawings above that at the pivot point 102 of the slot end 103 on the reference line 80 Normal is led out to corner 105. Then it leads continuously to the end 98 of a transition contour part 99 with a cam surface 100, the distance 101 from the pivot point 102 of the elongated hole end 103 at the wide wedge part 96 being greater than the radius 87.
  • a transition contour part 99 is up to that End 104 of the parallel outer contour surface 82 out.
  • the distances from the pivot point 102 are so larger than at the narrower area that when the railing straps are inserted - regardless of whether one or two railing straps 35 are inserted - the corner 105 of the lifting cam 97 or the cam surface 100 are hit, so that the lifting cam 97 is pivoted about the pivot point 102, which coincides with the center of the bolt 70 or its axis 90, as shown in FIG. 11. So, although the lifting cam 97 hangs in the insertion space 41, the insertion of the tab 35 can also be carried out without problems at distances and the railing rods 34 are temporarily secured against falling out to the side to such an extent that the assembly person is protected up to the wedge box 33 even in an unfavorable situation and the wedge 65 beyond the intermediate layer according to FIG.
  • the wedge 65 is expediently particularly fixed by a hammer blow from above. It can be unlocked by hitting it from below under wedge 65.
  • the figures illustrate that the wedge 65 protrudes slightly beyond the side walls 42 and the slotted walls 66 even when two railing tabs 35 are inserted and can thus be operated properly.
  • the reference line 80 does not coincide with the longitudinal center axis of the elongated hole 75, but - as can be seen above all from FIG. 9 - is offset by the amount of the flattening 121 of the bolt 70 dealt with below and runs through the axis 90 of the bolt 70.
  • the radius 87 is also guided about this axis 90.
  • the previously described shape of the wedge uses the principle of allowing part of the outer contour of the wedge to slip through when it is not in the securing position.
  • the exemplary embodiment dealt with in FIGS. 13 to 17 shows wedge boxes in the same form and with the same reference numerals, but a wedge 115 which is centrally symmetrical with respect to the center of the reference line 80 between the pivot point 102 and that in the end 91 of the elongated hole 75.
  • This has two contact outer surfaces 78.1 and 78.2 and two lifting cams 97.1 and 97.2, the outer contour conditions of which are designed the same as they were dealt with in connection with the first exemplary embodiment.
  • the longitudinal center line of the elongated hole 75 and the reference line 80 for the displacement of the wedge 115 and the dimensioning of its outer contour coincide because both elongated hole walls of the elongated hole 75 are each supported on one of the two opposite flats of the associated bolt.
  • the bolt 70 with its bearing in the slot walls 66.1 and 66.2 is to be sensibly designed. Exemplary embodiments for the design of the elongated hole and the support are dealt with below.
  • the bolt 70 is therefore provided with a flattened area 121 in the support area. This lies between the slot walls 66.1 and 66.2 in the slot 61. Near its head 122, the bolt 70 has a cylindrical bearing surface 123 which has a diameter 124 which corresponds to the diameter of the bearing hole 125, taking into account the rotational play. At the other end, a shoulder nut 126 with a shoulder 127 and a bearing shoulder 128 is provided.
  • the bearing lug 128 has the same outer diameter 124 as the bearing surface 123.
  • the lug nut 126 is screwed against a support surface 129 of the bolt 70 on the external thread 130 of the same such that the head 122 and the shoulder 131 with little axial play on both sides of the slot walls 66.1 and 66.2 lie so that even if the bolt 70 is dirty, it can rotate in well-functioning bearing surfaces.
  • the distance 133 of the flattened portion 121 from the opposite outer wall line of the bolt is a little less than the width 77 of the elongated hole, the flattened portion 121 being so deep that, taking into account the play and wear of the bolt 70, the wedge 65 is pivoted and always rotates perfectly on the cylindrical bearing surfaces and lugs 123 and 128 firmly connected to it in the bearing holes 125 of the slotted walls 66.1 and 66.2. Then the supporting force is also transmitted in the diaphragm walls 66.1 and 66.2 with little surface pressure.
  • the thickness 136 of the wedge 65 is smaller than the outer width 63 of the corrugated wedge 65 because of the corrugated configuration.
  • the material thickness is matched to the size of the flattening 121 taking into account the forces occurring and to the sizes of the Storage areas in the slot walls 66.1 and 66.2 matched.
  • the bolt shown in FIG. 4 shows - without further explanations - two flats lying at the same distance from the axis 90 and is therefore intended for the symmetrical wedges 115 with two lifting cams 97.1 and 97.2. Its storage is designed accordingly.
  • FIG. 19 Another possibility for the low-wear support of a pivotable symmetrical wedge 115 or, analogously, also of a simple wedge in each case on a large flattened support surface 141 is shown in FIG. 19.
  • a support cylinder 140 is rotatably mounted on a fixed bolt 139. This is designed taking into account the clearance and width 62 of the slot 61 and is seated on the bolt 139 with rotational play.
  • a simple, fixed bolt can then be inserted and clamped through a correspondingly large bore in the slot walls 66.1 and 66.2.
  • FIG. 20 Another variant for supporting the wedge forces on a relatively large area is shown in FIG. 20 Elongated hole, which in the area of its two ends each has a rotating part 150.1 and 150.2 slightly beyond 180 ° wrap, the radius 151 corresponding exactly to the radius of the outer wall of the support bolt 152 which is to be fixed firmly between the slotted walls 66.1 and 66.2.
  • the support bolt 152 has the flattened portion 121.
  • the wedge can be moved in the desired wedge position in the slot 155 over the entire area, so that when one or two tabs are wedged there is always a large contact surface for supporting the forces .
  • the wedge if the wedge is in its end positions, it can rotate freely because of the part-circular design of the rotating parts 150.1 and 150.2 of the elongated hole 155.
  • FIGS. 21 and 22 Another variant for large-area support of the wedge forces is shown in FIGS. 21 and 22.
  • a flat-oval support bolt 160 is fastened in the slot walls 66.1 and 66.2 so that they penetrate and are secured against rotation.
  • a suitable long oval, inclined profile hole 161 can be provided in each diaphragm wall.
  • the ends can be fastened in a suitable manner by means of screws, split pins, wedges or the like.
  • the flat oval profile is dimensioned such that the flattening 121 serving the system is dimensioned according to the supporting forces that occur, while the two outer end regions here, for example, as Semicircle 162 are designed and the intermediate back surface 163 is also flat. It can be curved as well.
  • the outer distance 165 of the two vertices of the circles 162 assigned to the end faces is slightly smaller than the width 77 of the slot 75.
  • the wedge can be supported on the flattened portion 121, but can also be freely pivoted around in the region of the ends of the elongated hole in order to serve the purposes previously described.
  • a wide range of further configurations for large-area support and free rotation of the wedge at the ends of the elongated hole can be carried out within the scope of the invention.
  • the wedge can also be made thicker and the diaphragm walls can move further apart.
  • the present box shape is optimized in terms of stability, material expenditure and size for the practical problems that arise, especially since neither the outer corners of the wedge box nor the wedge itself should protrude too far into the working space of the scaffolding, since the railings are to be attached to the inside of the stems of the scaffolding are in order to create favorable conditions for the railings and the ability to assemble the scaffolding and thereby to ensure that the wedge boxes with their wedges cannot be a hindrance when passing from one field to another.
  • a material expenditure, occurring forces and protrusion optimized solution for the wedge and box designs shown in the drawings have been found.
  • a wedge box (33) is fastened to the stem (31.1) of a scaffold, in the insertion space of which either one tab or two tabs (35) of railing rods (34) can be inserted.
  • a wedge (65) which is displaceable and pivotable on a bolt (70) has an elongated hole (75) and a pressing-on outer surface (78) lying at a suitable wedge angle, at the upper end of which a lifting cam (97) is formed.
  • the bearing and outer contour of the wedge (65) are selected so that the insertion play (92) remains and the wedge can either slip through or be raised by means of the cam surface (100) or the lifting cam (97) when inserted.
  • the contact outer surface (78) and the elongated hole (75) are long enough, taking into account the wedge angle, in order to securely clamp one tab (35) or two tabs (35).
