Definitions

  • the invention relates to a system which comprises two coverings lying on top of one another and a securing means, a method for connecting two coverings and a securing means designed as a tension spring according to the preamble of claims 1 or 6 or 8.
  • U1 is a device for securing at least two scaffolding planks, made of metal, the device in the assembled state penetrates a hole in the plate of a first plank and a hole in the plate of a second, arranged under the first plank, and which consists of a wire bracket consists, on which two legs are formed which are connected to one another by a base and are provided with bends at their free ends.
  • the disadvantage of the prior art is that the hole in the first board, which is used for the connection, and the hole in the second board, which is used for the connection, have to overlap so that the device can be installed.
  • a tension spring with an eyelet arranged at each end is known, one of which engages in a frame, preferably a tubular frame, the other, however, in a link mesh covering, the eyelet being designed in such a way that the points of application of the link mesh covering or the tubular frame on the eyelets are almost flush with the upper edge of the mainspring.
  • a resilient fastening clip for connecting essentially plate-shaped parts lying flat on top of one another is known, the fastening clip resting with a support surface on the outside of the package of parts to be connected and engaging around the other parts of the package with a springy hook inserted through a recess in each of the parts, whereby At least one helical turn is formed at one end of a helical spring, the diameter of which exceeds the inside diameter of the recess of the plate-shaped part adjacent to this end of the helical spring, and the other end is shaped into a hook, the hook tip of which engages through the recesses of the plate-shaped parts .
  • a system which comprises at least two superimposed surfaces in the form of an upper surface and a lower surface and at least one securing means, the surfaces at least partially overlapping and each having a plurality of openings between an upper side which forms a running surface of the respective surface, and an underside, the securing means being designed as a tension spring, the tension spring comprising a first free leg on this side of a spiral winding and the tensioning spring being guided with the first free leg through one of the openings in the upper covering and resting on the upper side of the upper covering
  • the system according to the invention comprises at least two superimposed coverings in the form of an upper cover and a lower cover and at least one securing means, the coverings at least partially overlapping and each having a plurality of openings between an upper side, which forms a running surface of the respective covering, and one Include the underside, here it is provided that the securing means is designed as a tension spring, the tension spring on this side and on the other side of a spiral winding comprises a first free leg and a second free leg, the tension spring with the first free leg through one of the openings in the upper covering is guided and rests on the top of the upper covering and wherein the tension spring is guided with the second free leg through one of the openings in the lower covering and rests on the underside of the lower covering.
  • the tension spring can be arranged eccentrically in an opening in the upper covering and eccentrically in an opening in the lower covering, coverings in which the openings provided for the connection are offset from one another can also be connected to one another.
  • the system is tolerant of deviations in the alignment of the coverings and saves rework on the construction site, which would be necessary for an exact alignment of the coverings.
  • the system accordingly also has an elasticity that allows the coverings to move slightly with respect to one another so that the framework is not rigidly braced undesirably by the connected coverings.
  • the tension spring rests with one end face of its first free leg on the upper side of the upper covering and that the tension spring rests with a portion of a lateral surface of its second free leg on the underside of the lower covering.
  • the second free leg has an arcuate course in an area in which the section which rests on the underside of the lower covering is arranged. This makes it easier for the tension spring to be pushed onto the lower covering, since the tensioning spring only comes into contact with the lower covering with rounded sections.
  • the upper covering is designed in the form of a sheet metal bent on two opposite sides
  • the lower covering is designed in the form of a sheet metal bent on two opposite sides and that the spiral winding of the tension spring is in one between the Tread of the upper covering and the tread of the lower covering formed cavity is added, wherein a height of the cavity is predetermined by lateral webs of the upper covering.
  • the tension spring on this side and on the other side of a spiral winding comprises a first free leg and a second free leg, the first free leg being bent in a U-shape, the second free leg S-shaped bent in such a way that a first arc, which is closest to one end of the second free leg, viewed in the direction of a longitudinal axis of the tension spring, has a smaller distance from the spiral winding than a second arc, which is the end of the second free leg Leg is further than the first arc and has a greater distance from the spiral winding.
  • the Tension spring is ideal for pushing onto the lower covering, for placing on the upper covering and for a tension build-up and tolerance compensation between the upper covering and the lower covering, so that a congruent alignment of the covering can be dispensed with and so that an undesirably stiff Tensioning of the coverings is avoided.
  • a covering is to be understood as a scaffolding element of a scaffolding, which is also referred to as a walking floor or scaffolding floor and which makes it possible to step onto the scaffolding in the assembled state.
  • the system 1 comprises an upper covering 101, a lower covering 201, a first securing means 301 and a second securing means 401.
  • the securing means 301, 401 are designed as a first tensioning spring 302 and a second tensioning spring 402.
  • FIG. 1 shows a front view of the system 1, it can be seen that the upper lining 101 rests on the lower lining 201 and the two linings 101, 201 are connected by the two tension springs 302 and 402.
  • Figure 2 is the representation of the Figure 1 shown in perspective view.
  • Figure 3 is the representation of the Figure 1 or.
  • Figure 2 in side view corresponding to that in the Figures 1 and 2 indicated arrow directions III shown. This side view is shown in section in the area of the second tension spring 402.
  • FIG. 3 is a section through the system 1 corresponding to one in FIG Figure 3 shown sectional plane IV-IV, wherein the first tension spring 302 is cut and wherein the second tension spring is hidden.
  • the Figures 5 and 6 show by way of example the first securing means 301, which is designed as a first tension spring 302, in a perspective view and in a side view.
  • the second securing means 401 is designed corresponding to the first securing means 401.
  • the coverings 101, 201 partially overlap and point between an upper side 102 and 202, which is a running surface 103 or 203 of the respective covering 101, 201, and an underside 104 or 204 in each case a plurality of openings 105, 106 or 205, 206, which are only designated as examples.
  • the first tension spring 302 on this side and on the other side of a spiral winding 303 comprises a first free leg 304 and a second free leg 305.
  • the second tension spring 402 (see in particular Figure 1 ) is constructed accordingly and comprises a first free leg 404 and a second free leg 405 on either side of a spiral winding 403.
  • the first tension spring 302 is guided with the first free leg 304 through the opening 105 of the upper covering 101 and lies on the upper side 102 of the upper covering 101, namely on the running surface 103 of the upper covering 101, with an end surface 306 (see FIG Figures 5 and 6 ) of the first free leg 304.
