Definitions

  • the invention relates to a device for securing on roofs, in particular flat roofs, active persons according to the preamble of claim 1.
  • each person uses a safety harness from a to be applied to the upper body of the person seat belt and at least one safety line.
  • the safety line is connected at one end to the seat belt worn by the person, while the other end of the safety line is connected to one of, preferably, a plurality of fasteners on the roof.
  • Each of these fasteners is part of the device according to the invention.
  • the person working on the roof can always hook himself with the safety line in the vicinity of their work on the roof in the nearest or easiest to reach fastening means of the device and thus secure against falling from the roof.
  • the respective fastening means is anchored by a connecting means with the roof fixed. This anchorage must be designed so that it is stable enough in all circumstances and does not affect the tightness of the roof.
  • known devices of this type serve as connecting means for arranging the fasteners on the roof pieces of roofing membranes, which are glued to the underlying, existing roofing membrane and / or welded.
  • this type of attachment of the device on the roof is relatively easy to produce, the device gets its grip on the roof but only by the glued or welded roofing sheet.
  • the known connection means no longer ensure adequate retention of the fasteners on the roof more.
  • Such durability problems also arise when older roofs are to be retrofitted with the device and the existing roofing sheet does not provide sufficient support due to its age the glued or welded roofing sheet piece. This is especially true when a fastener is heavily and / or jerkily charged.
  • the present invention seeks to provide a simple device for securing on roofs, in particular flat roofs, active people who provides a solid, lasting hold and also leads to no leaks in the roof.
  • An apparatus for achieving this object has the features of claim 1.
  • By forming at least some connecting means for positive and / or frictional connection of the respective connecting means with the roof there is a firm hold of the fastener on the roof.
  • the maintenance of the fastener on the roof is not dependent on outside temperatures and the age of the roofing membrane due to the positive and / or frictional connection.
  • the fastening means are "nailed" by the positive and / or frictional connection means quasi on the roof and / or "festgekrallt".
  • the positive and / or frictional connection means are according to a preferred embodiment of the device for coupling the fastening means to a below a roof membrane lying roof base formed.
  • the positive and / or non-positive connection means extend obliquely to the surface of the roof.
  • the connecting means may act in the manner of claws when the anchored by the connecting means on the roof fastener is loaded. Since usually a plurality of connecting means are arranged around the fastening means, a connecting means is always pulled under load of the fastening means in the manner of an anchor in the roof base due to the oblique course of the connecting means. A release of the fastener even under high load is thus virtually eliminated.
  • the device supporting means are assigned to the frictional and / or positive connection means.
  • the support means ensure that the connecting means maintain their position even under extreme load of the fasteners at least almost and do not deform. Loosening of the fastener under load is thereby effectively avoided.
  • the positive and / or frictional connection means are formed as substantially flat tongues with a sword or blade-like shape.
  • the flat tongues create relatively large contact and support surfaces under load of the fasteners.
  • the tongues exert only a relatively small surface pressure on the material of the roof substructure when the device is loaded.
  • it is possible to reliably fix the device with the tongues in an insulation of the roof substructure by the supporting forces are directed substantially perpendicular to the surfaces of the tongues.
  • the tongues are each at least tapered towards a free end, in particular pointed.
  • the edges of the tongues are deburred, in particular rounded. Alternatively or additionally, it is provided to polish the tongues, at least their edges.
  • Rounding and / or polishing the tongues avoids a notch effect when the tongues are operated through the roof substructure.
  • the tongues extend obliquely through a lying on the roof surface support plate of the fastening means.
  • the tongues thereby form claws for reliable anchoring of the fastener in the roof.
  • a plurality of tongues are distributed around the fastener, wherein the pointed free ends of all tongues converge obliquely to the vertical center axis of the device, creates a total umbrella-like anchoring of the fastener on the roof, regardless of the direction of the force acting on the fastener force the Tongues pull plow-share or anchor-like into the roof substructure.
  • the holding force of the fastener is reinforced with increasing load, which leads to a reliable under all circumstances the device, in particular the fastening means of the same, on the roof.
  • the tongues are further guided in the support plate, preferably in such a way that they are kept largely immovable in the support plate.
  • the tongues can not appreciably change their relative position, in particular their oblique orientation relative to the support plate, even when the device is loaded.
  • the tongues thereby claw the support plate with the fastener substantially rigidly in the roof base, even if the tongues are not additionally held by support means.
  • the lower platen has a central raised portion, which is preferably formed by a frustoconical ring portion. Slit-like openings for the positive reception of the end regions of the tongues directed away from the pointed ends are associated with the central raised area.
  • the attachment points of the tongues are located on the support plate at a distance from the top of the flat roof.
  • the apertures are formed corresponding to the end portions of the tongues, whereby the tongues are immovably supported in the apertures.
  • the tongues are held in the openings of the support plate is substantially rigid. As a result, the tongues do not change their obliquely directed to the surface of the roof course, even if the device loads, or at least not appreciably.
  • a reinforcement in particular an extended guide
  • the openings may be assigned support means. Thereby, the substantially immovable fixation of the tongues in the support plate is further improved.
  • support means provide an additional connection of the support plate with the tongues.

  • each tongue is associated with a support means. It is thereby intercepted each tongue by its associated support means.
  • the support means are designed as screws. These may be threaded screws, but also self-tapping screws.
  • the support means may also be designed as rivets, in particular hollow rivets. Both with the screws and with the rivets, it is possible to tension the tongues against the direction in which they have been driven into the roof, in particular the roof substructure. Preferably, thereby the angle of the tongues relative to the surface of the roof becomes smaller. As a result, a backlash-free, biased clamping of the support plate with the support means on the roof is possible.
  • each tongue is formed as a support tab.
  • the preferably flat support tab has a tongue-like shape.
  • the surfaces of the support tabs are slightly larger than the tongues.
  • Each support tab like the screw, serves to lock the direction or inclination of the tabs relative to the surface of the roof, thereby securely securing the support plate to the fastener on the roof.
  • each securing tab has a preferably slot-like opening through which a tongue can be inserted obliquely or transversely through each.
  • the respective tongue can be inserted through the opening in the respective support tab without jamming, this breakthrough is greater than the cross-section of the respective tongue formed.

  • Each tongue 30 is associated with its own support tab 48.
  • Each of the identically formed, tongue-like, flat support tabs 48 is tongue-like, essentially flat.
  • the surface of the respective support tab 48 is larger than that of the tongue 30, in particular, the support tabs 48 are wider than the tongues 30.
  • the support tabs 48 are just as the support plate 20 associated with the screws 35, namely in the region of the circular, planar central elevation 22nd held.
  • the flat support tabs 48 are arranged on a pitch circle about the longitudinal center axis 34 of the eye bolt 16 and the threaded bolt 17, in such a way that they are perpendicular, so cut the support plate 20 at a right angle.
  • the support tabs 48 are aligned tangentially to this pitch circle, in such a way that their surfaces form a tangent to the pitch circle.
  • the tongues 30 can be obliquely inserted through the flat side of the respective support tab 48, namely at a corresponding opening 49 in the respective support tab 48.
  • the opening 49 is dimensioned slightly larger than the cross section of the tongue 30 in that area in which he cuts the respective support tab 48.
  • the respective tongue 30 extends with play through the support tab 48.
  • the slit-like tongue shown in FIG. 8 has at the lower transverse edge on a bulge 52 extending over the central region thereof.
  • Such a bulge 52 may also be arranged on the upper or alternatively only on the upper transverse edge of the slot-shaped opening 49.
  • a bulge 52 may also be arranged on the upper or alternatively only on the upper transverse edge of the slot-shaped opening 49.
  • Each support tab 48 has at the upper end two opposite extensions 50, which act like nail heads and prevent complete passage of the support tab 48 through the slot 47 in the region of the central elevation 22 of the support plate 20.
  • the head 51 of each support tab 48 can also have an otherwise nail-head-like enlargement, which reliably holds the respective support tab 48 in the slot 47 of the support plate 20.
  • the tongues 30 extend obliquely through the substantially vertical support tabs 48 (Fig. 6), the tongues 30 are supported in the region of their lower ends by the support tabs 48.
  • the tongues 30 can not shift appreciably, so change their direction only in the scope of the game between the respective tongue 30 and the support tab 48 in the region of the slot 47 thereof.
  • the present embodiments of the invention relate to a flat roof 10.
  • the invention is also suitable for all other roofs, in particular inclined roofs.
  • the devices can alternatively be applied directly to a roof substructure. Then the devices are also suitable for roofs that are not provided with roofing membranes 12, but roofing tiles, roof tiles, slate or the like.
  • FIGS. 9 and 10 show a fifth embodiment of the device according to the invention. This device corresponds in principle to the device according to the fourth embodiment (FIGS. 6 to 8). Therefore, the same reference numerals are used for the same parts.
  • Figure 9 shows approximately the true proportions of the device.
  • the devices of the first four embodiments have similar proportions, even if they are shown differently in FIGS. 2 to 8, which has been done only for the sake of clarity in these figures.
  • the roof substructure shown in FIGS. 2 to 4 and 6 with the insulation 11 and the roofing membrane 12 is absent.
  • the device of FIGS. 9 and 10 is in principle to be arranged on the same or similar roof substructure.
  • a roof track rosette may be arranged above the roof track 12, in particular when it is an older or insufficiently resistant roof track 12, which extends over at least the entire area of the device, in particular its (lower) support plate 53.
  • the roof track rosette can also have a slightly larger diameter.
  • the roof track rosette is formed from a new roofing membrane glued to the lower roofing membrane 12 prior to assembly of the device and / or welded, in particular a high-strength roofing membrane.
  • the device of FIGS. 9 and 10 differs from the device of FIG. 6 initially in that the support plate 53 is planar.
  • the flat support plate 53 has a circular base.
  • a spacer 54 is arranged in the device shown here.
  • the flat spacer 54 is loosely placed on the support plate 53.
  • the preferably circular spacer 54 has a central through hole 55 through which the threaded bolt 41 extends. This is the result Spacer 54 held on the threaded bolt 41 centered to the support plate 53.
  • the spacer 54 In the area of heads 56 of the tongues 30 and heads 51 of the support tabs 48 which rest on the flat support plate 53 and project upwardly, the spacer 54 has openings 58 and 59 which correspond to the heads 56 and 51 of the tongues 30 and Support tabs 48, in particular slightly larger, are formed.
  • the spacer 54 has a thickness sufficient to fully receive the heads 56 of the tongues 30 and the heads 51 of the apertures 46 so that the heads 56 and 51 do not protrude above the planar upper surface of the spacer 54.
  • the diameter of the spacer 54 is selected in the illustrated embodiment so that it ends slightly outside the outer heads 56 of the tongues 30 and in the surface of the spacer 54, the outer apertures 58 are still recording.
  • the support plate 53 is provided with a larger diameter. It is also conceivable to choose the diameter of the support plate 53 and the spacer 54 about the same size.
  • a roof sheet 14 is also covered in this device by a roof sheet 14.
  • this is a circular rosette, which is larger in diameter than the support plate 53, so a circular ring area of the roofing sheet 14 surrounding the support plate 53 rests on the roofing sheet 12 or a reinforcing layer thereof and can be sealingly connected thereto, for example by gluing and / or welding.
  • a central through hole 60 for the threaded bolt 41 and the roof track piece 14 is guided on the threaded bolt 41 and centered centered.
  • an upper support plate 19 is mounted from above. This is provided in the central region with a bulge, that is approximately as formed as the upper support plates 19 of the previously described embodiments of the device. Above the support plate 19, in turn, a ring nut 38 is provided, which is screwed with a threaded bore 40 on an external thread of the thread at least at the upper end portion of the threaded bolt 41.
  • the ring nut 38 is integrally connected to the support plate 19, preferably welded. As a result, the support plate 19 is mounted together with the ring nut 38 by screwing the ring nut 38 on the upper end of the threaded bolt 41.
  • a lock nut 42 for securing the ring nut 38 against unintentional release can be dispensed with in the embodiment shown, because the support plate 19 is integrally connected to the ring nut 38 and the support plate 19 is elastically deformable by the middle bulge and thereby secures the ring nut 38 on the upper end of the threaded bolt 41 against unintentional release.
  • Fig. 11 shows a guide means 61 for guided mounting of both the oblique tongues 30 and the vertical support tabs 48.
  • the guide means 61 has a base plate 62 which is provided at one end with a through hole 63 which corresponds to the diameter of the threaded bolt 41st is trained. Thereby, the guide means 61 can be pushed with the through hole 63 in the base plate 62 on the threaded bolt 41 and rotated around it. In this way, the guide means 61 can be reliably positioned by appropriate rotation at those points where the tongues 30 and the support tabs 48 are to be inserted through the lower support plate 53, namely via the slots 28 and 47 for the tongues 30 and the support tabs 48 in the support plate 53.
  • the guide 61 has vertical guide channels 64 for the vertical support tabs 48 and obliquely directed guide channels 65 for the oblique tongues 30.
  • the guide channels 64 and 65 is determined by the guide means 61, the direction of the oblique tongues 30 and the vertical support tabs 48 when driving the same in the roof base and thereby also ensures that the oblique tongues 20 when driving into the roof base, the openings 49 in the support tabs 48 meet, as shown in Fig. 10 is particularly clear.
  • connecting means in particular tongues 30, and partly an equal number of supporting means are provided.
  • the number of connecting means, in particular tongues 30, can be greater or less than four. The same applies to the proppant.
