Definitions

  • Toe boards are required on scaffolding to prevent objects or people from sliding sideways off scaffolding floors or platforms. They are made from wooden boards, metal profile parts or composite materials in a length that corresponds to the respective scaffolding floor or the grid size of the platform or the like. Fittings are attached or formed at the ends. These serve to secure the toe boards in position.
  • German utility model DE-U-19 60 069 it is customary to provide a U-profile plugged over the end of the toe board with a welded-on or trained eyelet, which is inserted in the appropriate position by means of mandrels or pins protruding from the supporting parts of the frame will.
  • the eyelets of both ends of the toe board are provided at different heights, so that the eyelets of adjacent toe boards are stacked on top of each other Pin are threaded, the toe boards are at the same height and the fittings are only arranged on the toe board up to about 60% of the height.
  • the eyelets are mounted in such a way that the eyelet at one end of the toe board is arranged at the top to a reference line offset to the center, while the eyelet at the other end of the toe board is offset from this reference line.
  • the toe boards not only have to be used at the same height but also always in the same position of use and attached to the pins.
  • measures for correct position securing are required.
  • These toe boards can only be used for scaffolds that have appropriate retaining pins. In the case of scaffolding that can be used in a variety of ways and that can also be arranged around curved building surfaces, these toe boards are unusable.
  • a toe board for scaffolding which shows fittings on the toe board, in which an overhead fitting part with a shell projecting outwards is provided at one end of the toe board, while at the other end of the same toe board a fitting part is provided in the lower area, which likewise has an outer shell which, in the position of use, surrounds the handle.
  • this has an extension projecting downward beyond the toe board, which is assigned to the support in a specific position of use.
  • the toe boards are not intended for use on a cover, but are to be used in the intended position of use and are therefore only intended for a very specific toe board and scaffold configuration. Also pay attention to the respective position when fastening to the toe board.
  • the invention has for its object to provide a toe board training with the features mentioned above so that the toe boards hold on the handle in any angular position and two adjacent toe board fittings do not hinder this holding that toe boards of adjacent fields can be mounted at different heights and that Fittings during stacking are not a hindrance for storage and transport and the toe boards have to be strung together on a cover.
  • the toe boards can be strung together on a cover and arranged at any angle to one another, because the holding parts encompass the handles and themselves do not hinder each other and are not hindered by other fastenings if they take into account the height of the respective fastenings such as wedges or the like.
  • the toe boards equipped in this way can now also be used in the usual way on all standard scaffolding, regardless of whether pens are present or not. They can therefore be used for old scaffolding and for scaffolding on right-angled buildings, but also allow them to be used for scaffolding of curved surfaces in the following way. This is because alternating right-angled and oblique-angled fields are then strung together. In the fields equipped with right-angled floors, the toe boards with the holding parts located at the bottom are hung in such a way that parts of the associated holding parts, if necessary, engage behind the inner wedge, which, as before, does not prevent the toe boards from being fastened but supports them.
  • the toe boards assigned to the fields closed at an oblique angle and correspondingly designed scaffold floors are then hung in with holding parts located at the top, so that they engage the two stems above the holding parts of the adjacent toe boards located below. Since the fields are completed alternately at right angles and skewed angles in a sensible scaffolding, because the load-bearing crossbars are to be connected at right angles to the longitudinal extent of at least one of the adjacent toe boards, if possible, there are no difficulties with the alternate insertion of the toe boards, so that with the one toe board with both holding parts below and with the next toe board both holding parts to the top.
  • the measure provides that the fittings are each formed with a flat part, which is equipped with a wrap-around part that lies outside the surface of the toe board and engages around the associated handle from the side of the toe board, that in the direction of Longitudinal extension of the toe board over this protruding flat part then with a corresponding, tongue-like element abuts the handle from one side, while the encompassing part is guided around the handle and can secure against lateral displacement in the other direction and against longitudinal displacement of the toe board.
  • the design of the fittings can be solved in many ways, depending on the existing fastening parts of other elements of the scaffolding and the hanging and support conditions.
  • a particularly useful provision provides that the two encompassing parts of each toe board are each formed by a stable rod which is angled or bent to form a hook and which is preferably fastened centrally on the protruding tab of the flat part in such a way that the two stem contact areas for securing against longitudinal displacement of the Toe boards have a distance which corresponds to the inner distance of only two stems arranged in grid spacing, which is reduced only by the insertion clearance, and the outer contact area of which lies at a distance from the flat part corresponding to the thickness of the stalk.
  • a relatively thin rod has the advantage that it takes up the least possible space when installed at an oblique angle and during storage and can nevertheless be designed to be sufficiently stable. Correspondingly narrow designs can also be achieved by designing a uniform fitting. It is important to take into account any obstacles in assembly, use and storage. It can be provided that the flat part also protrudes beyond the center of the height in the fastening area and in the edge area, but not in the area of engagement of other tabs, and thus contributes to the stability of the entire arrangement with the least effort.
  • the flat part can expediently consist of a rectangular flat steel section or stamped sheet metal part, on which a corner area which is the same as the size of the tab engaging on the handle is cut out. The same flat parts are to be used on both sides of the toe board. Only the bent rods or other formations need to be attached to different sides of the tab. Further details, features, refinements and aspects of the invention are also dealt with in the following description part, drawn up with reference to the drawings.
  • FIGS. 2 and 3 show a single toe board 20 which can be formed from a wooden board which may have been glued from several strips, from an extruded light metal profile or from a composite material, possibly with the aid of plastic. It has a length L which corresponds to the length of the assigned scaffolding floors and which is between approx. 70 and approx. 400 cm.
  • the toe board has a height H which is sufficient for nothing to slide off to the side and which, for example, is approximately 15 cm. It has a thickness D, which is usually about 25 to 50 mm.
  • fittings 22.1 and 22.2 are fastened, specifically on the outside 23 of the toe board 20, so that they project over the surface 23.1 of the toe board 20 as a whole.
  • the flat parts 25 of the fittings 22.1 and 22.2 are punched out of stable steel sheet in the form shown in FIG. 2 and riveted to the outside on the toeboard 20 with the aid of, for example, two rivets 27. They each carry a wrap-around part in the form of a hook 26.
  • the design is such that the holding parts formed by a rectangular tab 25.1 and the hook 26 protrude outward at both ends of the toe board 20 both over the ends 21.1 and 21.2 and also over the surface 23.1, so that they are designed to extend in two directions.
  • the flat part 25 is designed with a corner cutout 25.2 of the same size as the tab 25.1.
  • the hook 26 is placed, for example welded or riveted into a bore with a pin.
  • the hook 26 is formed by a stable rod, for example made of round steel or a rod which is rectangular, in particular square, in cross section, and - as can be seen in FIG. 3 - is bent outwards.
  • the design is such that the stem contact areas 26.3 and 26.4 of both hooks 26.1 and 26.2 are at a distance A which corresponds to the inner distance IA of two adjacent stems 11 (FIG. 1), which are only reduced by the insertion clearance.
  • the outer contact areas 26.5 and 26.6 have a distance AA from the surface of the tab 25.1, which corresponds to the thickness or the diameter DS of the stems 11, so that, as can be seen, the securing in two directions is ensured by each hook and the associated tab.
  • the toe boards 20 can be stacked lying on the envelope so that the hooks 26 of one toe board engage in the corner cutouts 25.2 of the adjacent toe board and even beyond in the free area of the next toe board.
  • the flat parts 25 are designed so that the fastening area 25.3 is twice as wide as the tab 25.1 and extends to the other side of the height center HM, so that the two rivets 27 can be attached at a large distance from one another.
  • the fastening area 25.3 protrudes by a small amount as the edge protection area 25.4 over the end 21.1 or 21.2 of the toe board 20, as shown in FIG. 2. This extends into the free space, but not as far as the hook 26 is spaced from the end of the toe board. This overhang prevents the hooks from hitting the wood or the like of the next toe board when stacked. They lie with sufficient play in the corner cut 25.2 of the adjacent toe board.
  • the toe boards 20 serve to be used in scaffolding 10.
  • Such scaffolds have at least one handle 11 in each corner of each field, which can be shared by neighboring fields.
  • perforated disks 12 are attached to the stems.
  • connection shoes 13 of crossbars 14 attached and secured by driving in wedges 15 in a known manner.
  • Transversely extending, as U-profiles open up support bars 16 are attached in the same way and carry the scaffolding floors 17 in the usual way.
  • These can be designed in the usual way in a variety of ways.
  • special scaffold floors as described below, can also be used.
  • 1 and 4 show sections of a scaffold for which the toe boards 20 with their fittings 22 have been specially developed.
  • 1 consists of the fields 18.1, 18.2 and 18.3.
  • the fields 18.1 and 18.3 are rectangular.
  • the field 18.2 has parallel outer edges, but is closed at both sides at an oblique angle. This is achieved by setting up the stems 11 of the scaffolding fields 18.1 and 18.3 in a suitable position relative to one another and to the structure to be scaffolded in each case. This results in a shorter horizontal bar 14.2.
  • Usual rectangular scaffold floors 17 are suspended in the fields 18.1 and 18.3.
  • the field 18.2 is covered here with scaffolding planks 19 simply placed over the scaffolding floors 17 of the fields 18.1 and 18.3.
  • toe boards 20 which are assigned to the rectangular scaffold floors 17, lie on their edge - as can be seen on the right in FIG. 4.
  • Their tabs 25.11 are below the height center HN and between the stem 11 and the outer edge of the wedge 15, as clearly illustrated in FIG. 4. It can also be seen here that there is no space for a further fastening element of a toe board 20.
  • a completely identical toe board 20 is now used on the outside of the scaffold bay 18.2, only it is installed in the reverse order identified by the reference number 20.2, that is to say on a cover.
  • the holding parts are on the same side of the height center HM.
  • the lower edge of the toe board can rest on the higher scaffold planks 19 and the tab 25.12 can now, as can be seen in FIG. 4, move freely at a distance corresponding to the thickness of the scaffold board 19 above the tab 25.11 of the toe board 20.1 on the right plugged into the handle 11 and pivoted around it and is secured with its hook.
  • the wedge 15.1 of the horizontal bar 14.1 connected at an oblique angle does not hinder the arrangement. Since the next field is again a field connected at right angles, a toe board with tabs 25.1 located below can be assigned to it.
  • Fig. 5 illustrates a somewhat different situation, in which the attack of the hooks 26 is shown, and the angle between the two toe boards is somewhat larger.
  • FIG. 6 illustrates how one toe board 20.1 with tabs 25.1 and hooks 26 underneath and the other toe board 20.2 with tabs 25.1 and hook 26 at the top is inserted into one and the same scaffold field on an outside corner, the edges of the tabs touching one another or run at a short distance from each other because the toe boards 20.1 and 20.2 are both supported on the same scaffolding floor 17.
  • FIGS. 7 to 9 illustrate an arrangement in which rectangular scaffolding floors 17 are arranged directly next to one another in rectangular fields for scaffolding sections which are straight for a longer period of time and in which the toe boards 20.1 and 20.2 are alternately inserted with holding parts 25.1 and 26 at the bottom and at the top and attached to the Stems 11 are secured.
  • the toe board design shows over the ends (21.1, 21.2) of the toe boards (20) protruding tabs (25.11; 25.12) which are attached to the same side of the center of the height of the toe board (20.1, 20.2).
  • the holding parts on one and the same handle (11) lie on the bottom and on the other onboard board (20.2) on the top.
  • Corresponding hooks that grip around the outside of the steep section secure the toe boards (20.1; 20.2) against axial displacement and lateral tilting.
