Definitions

  • the present invention relates to a use of a device for securing people against falling, in particular from a roof, but also from a wall or the like, comprising a base plate that can be attached to a surface with at least one recess arranged on the base plate with a recess wall and its use.
  • Fall protection devices are known from the prior art. Fall protection is used to prevent falls when staying or working in areas where a fall can lead to injuries due to the possible height of the fall. It is known that devices for securing people against falls often have a footplate and a post or an eyelet.
  • WO 02/48480A1 describes an anchor for attaching a working line to a structure.
  • the anchor has a plate with a position for the working line.
  • At least one friction plate and one belt are also provided.
  • the plate and the friction plate are located on opposite sides of the structure and are connected to each other by the strap so that when the plate is loaded, the working line creates a clamping force between the plate and the friction plate.
  • WO 02/14625A1 describes a method for mounting a roof anchor on a roof support structure having an underside, the roof being wholly or partially covered with roofing material, the roof anchor having a fastener and a rod.
  • US 2012233958 discloses a use of a device according to the preamble of claim 1.
  • fall protection with a base plate and an upwardly projecting post is used in the DE 10 2006 041 592 A1 described.
  • the upwardly projecting post that stands on the base plate is, for example, a steel tube with an eyelet at the upper end.
  • Fall protection of this type must be designed for two load cases.
  • One load case is to secure the post against impact if a person working on the roof accidentally hits the post.
  • a lateral impact force of 70 kg is allowed a specified deformation value of, for example, 10 mm cannot be exceeded.
  • DE 10 2006 041 592 A1 discloses a fall protection system in which a post protruding from a base plate is provided, the base plate being attached to a trapezoidal sheet of the roof structure. If a fall occurs, the lever arm formed by the post is extended by the foot plate, so that an increased torque occurs. This leads to higher forces acting on the roof structure and, in the event of a fall, the trapezoidal sheet metal of the roof structure is significantly deformed over a wide area, so that the roof structure then has to be extensively renewed.
  • the device When it comes to fall protection, there is the problem of the size of the device, especially during transport.
  • the device generally has a large, flat support or base plate and a long post on which an eyelet is arranged for passing a rope through. These are sold fully assembled and take up a lot of space during transport. There is therefore a need to provide a device for securing people against falls, which makes transport easier.
  • the object of the present invention is therefore to provide a use of a device for securing people against falls, which has a smaller size during transport, but also when stored at the manufacturer or on site.
  • different posts in particular posts of different lengths, should be adapted to the support and attachable.
  • This object is achieved according to the invention by using a device mentioned above for securing people against falling, in particular from a roof according to claim 1.
  • the base plate can be attached to a fixed element, for example a roof, a facade or another building element.
  • the base plate can be attached, for example, with screws or rivets.
  • the base plate preferably has fastening holes, in particular for fastening with screws and/or rivets.
  • the material of the base plate is preferably selected from a group comprising high-alloy stainless steel.
  • the base plate is preferably round, but can also be designed as a trapezoidal sheet, square, in particular square, or otherwise triangular or polygonal.
  • the material thickness of the base plate is preferably in the range of approximately 1 to 8 mm, more preferably in the range of approximately 3 to 5 mm.
  • the size of the footplate is preferably in a range between approximately 300 and approximately 650mm.
  • At least one recess with a recess wall is arranged on the base plate.
  • the recess is preferably a blind hole, a depression, an opening, a through hole or a cavity.
  • the recess wall of the recess is a side wall surface of the recess.
  • the size of the recess is in the range between approximately 0.1 and approximately 3mm.

  • a thread is a profiled notch that runs continuously helically, ie as a helical line, in a cylindrical wall.
  • the thread flanks are preferably designed as flat threads, round threads, buttress threads, pointed threads, trapezoidal threads or Whitworth threads (conical threads).
  • At least one, preferably exactly one, recess for the connecting piece is formed on the base plate.
  • the recess and the base plate can be central, be concentric or non-centric. The advantage of centering is that the strength of the base plate is independent of the direction of a force acting on the component that is connected to the connecting piece.
  • the device has at least one connecting piece.
  • the connecting piece is a part, section, link that connects two things together, in particular the base plate with a component.

  • a peripheral surface of the receiving area is at least partially connected, preferably firmly connected, to a recess wall of the recess in the foot plate.
  • the peripheral surface of the receiving area is at least partially cold-welded to a recess wall of the recess in the base plate. Welding is the permanent joining of components using heat and/or pressure, with or without welding filler materials.

  • the respective circumferential surfaces opposite the conical ones are essentially cylindrical, although in the case of the preferred embodiment, even if a solid material is present, for example when a post is formed, no such inner circumferential surface can be present in the area of the conical region.
  • a circumferential surface of the conical region is at least partially cold-welded or when the guide region is screwed to a component.
  • the advantage of cold welding is that no additional material or additional work step is required when connecting a component that can be arranged on the connecting piece, in particular a post or an eyelet or similar component is used for fall protection from a building, a roof, a ceiling or a system or machine with which a base plate is required.

  • the base plate itself is preferably fixed in a manner known per se by at least one screw connection or rivet connection to the surface, for example on a trapezoidal sheet metal. If a fall occurs, the tensile force is introduced directly into the connections of the base plate via a safety rope and a metal cable connection.
  • the metal cable connection can, for example, comprise a stainless steel cable. This is corrosion-resistant and, with a diameter of, for example, 6 mm, can easily absorb the required tensile force of more than one ton.
