Definitions

  • the invention relates to a single step for an inclined
  • Roof with a platform that can be entered and a bracket that supports the platform, the platform being laterally delimited by at least two upstands, of which the first upstand has a handle that protrudes above the platform, and the bracket can be connected to a roof covering plate so that it can be adjusted to the inclination of the roof .
  • Inclined roofs must be able to be entered and walked on for the purpose of inspecting, servicing and maintaining systems such as chimneys and antenna systems. In order to ensure the highest possible level of security when walking on a roof, individual steps are subject to uniform standardization.
  • a single step corresponding to the European draft standard, prEN 516 or a German standard, DIN 1860, T.5 is known from the Braas manual '94 / 96, Inclined roofs, p. 46, Fig. 3.
  • the well-known single step has a platform that can be entered and a bracket that supports the platform.
  • the single step is with the bracket to the inclination of the
  • Adaptable roof connectable with a roof covering plate The platform is laterally delimited by two upstands formed as narrow webs, of which the first upstand is designed as a handle that projects beyond the platform and the second upstand is designed as a flat stop.
  • the person walking on the roof can put their shoe on the flat stop when entering the single step.
  • the fitting of the shoe represents an asymmetrical load case for the narrow stop, which can lead to the stop breaking off and thus to the side sliding off the platform.
  • the object of the present invention is to provide a single step for an inclined roof which offers the greatest possible security against sliding off the platform from the side and against damage to the single step as a result of asymmetrical loading.
  • both upstands each have a stiffening which is arranged approximately at right angles to the upstand and has a width of at least 10 mm at least in the region of the longitudinal center of the platform.
  • the shape of the upstands is particularly stable, which can have a T, cross or angular cross section.
  • Such upstands have large moments of resistance to bending stresses occurring, so that breaking of the upstands is prevented.
  • the single step according to the invention therefore offers the greatest possible security against lateral slipping off the platform.
  • the right-angled arrangement of the stiffener makes it possible to design at least one of the uprights as a wide handle with a wide grip area. In the event of stumbling, in contrast to the previously narrow design of the handle, a painful cutting of the handle into the palm of the hand is prevented.
  • the design as a wide handle can take place through the base of the T-shaped cross section, so that the upstand has a wide rectangular gripping surface.
  • the horizontal leg of the angular cross section can form the wide grip surface.
  • a handle that is particularly easy to hold is created when the stiffening of the upstand has a curved cross-sectional shape.
  • the curvature of the stiffening can be made convex towards the grip surface, so that the grip surface is optimally adapted to the shape of the hand.
  • the grip surface can have a particularly rough surface or a profile in the form of knurling.
  • the single step offers a particularly aesthetic appearance if the width of the reinforcement increases from the ends of the upstand towards the center of the upstand, so that the reinforcement can be designed like a fish-bellied carrier.
  • each upstand can have an engagement opening in the region of the longitudinal center of the platform, so that the stiffening serving as a handle can be completely encompassed.
  • the cross-section of the stiffening should be curved on its underside, which serves as the gripping surface.
  • a single step with particularly ergonomically designed handles is created when the stiffening of the upstands is arranged in the area of the opening at the top of the opening.
  • the platform is advantageously designed to be non-slip. This can be done in a simple manner if the platform is profiled with web-like projections, knobs or the like. In addition, the platform may be rust-like with openings so that water or snow is prevented from accumulating.
  • the single step according to the invention can be mounted particularly easily on a roof covering plate if the roof covering plate has a support surface which is adapted to the lower contour of the retaining bracket and is provided with two fastening elements and a retaining bracket which is curved in a circular arc and which has openings for receiving the fastening means.
  • the openings are preferably formed by a series of round holes and by at least one elongated hole.
  • the Contact surface as part of a with the
  • Roof covering plate connectable bracket may be formed, or may be formed directly on the roof covering plate.
  • Threaded bolts are usually used as fastening elements.
  • the use of two threaded bolts can be dispensed with if one of the fastening elements, preferably the fastening element pointing towards the eaves, is formed with a gag arranged in the transverse direction, the distance between the contact surface and the underside of the gag equaling the thickness of the holding bracket and the thickness of the Gag is less than or equal to the width of the slot.
  • the axis of the neck of the T-shaped fastening element runs radially to the center of a circular arc which corresponds to the lower contour of the holding bracket.
  • the bracket can thus be placed with its elongated hole in the transverse direction on the T-shaped fastening element and, after pivoting in the longitudinal direction, connected to the second fastening element which can be introduced into one of the round holes.
  • the surefootedness when entering the single step can be increased if the platform is limited by an upstand on the ridge side.
  • the single step according to the invention is possible if the platform, the holding bracket and the uprights provided with stiffening are formed in one piece.
  • the single step can be produced using the die casting process, for example from an aluminum alloy.
  • Fig. 1 shows a single step according to the invention for entering an inclined roof in side view
  • Fig. 2 shows the single step according to the invention shown in Fig. 1 in section II-II.
  • the single step 10 is die-cast from an aluminum alloy.
  • the aluminum alloy contains about 10 to 11.5% silicon, about 1.8 to 2.4% copper and about 0.7 to 1% iron.
  • the single step 10 has a 250 mm long and 140 mm wide accessible platform 12 and a bracket 14 curved in a circular arc with a 148 mm radius.
  • the ends of the mounting bracket 14 and a web 16 extending from the center of the mounting bracket 14 are connected to the platform 12, so that the mounting bracket 14 supports the platform 12.

  • the platform 12 is laterally delimited by a first parallel upstand 24.
  • the first upstand 24 has an engagement opening 28 in the region of the longitudinal center of the platform 12 and a stiffening 30 arranged at right angles to the first upstand 24 on the side facing away from the platform 12.
  • Stiffening 30 is arranged in the area of the engagement opening 28 at the upper edge of the engagement opening 28, so that the stiffening 30 serves as a handle.
  • Fig. 2 the single step 10 of Fig. 1 is shown in section II-II.
  • the platform 12 is supported by the ends of the curved bracket 14 and by webs 16, 18 extending from the center of the bracket 14.
  • the platform 12 is laterally delimited by a first upstand 24 and by a second upstand 26 arranged parallel thereto.

  • the stiffeners 30, 34 are arranged in the area of the engagement openings 28 and 32 on their upper edge, so that the stiffeners 30 and 34 serve as handles.
  • the width of the stiffeners 30, 34 increases from the ends of the upstands 24 and 26 to the center of the upstands 24 and 26, so that the stiffeners 30, 34 have a width of 28 mm in the region of the longitudinal center of the platform 12.
  • Stiffeners 30, 34 have a convex curvature towards the grip surface, so that the handles are particularly good in the hand.
  • the platform 12 is divided into two tread areas 36, 38 which are arranged on both sides of the holding bracket 14.
