Abstract

The correspondingly dimensioned through passage hole (3) in the apex area of a dome (4) is formed with a cupola-shaped upper side and for the pipe (2) a conformably shaped hood (5) is provided. The superimposed position of the hood on the dome (4) is secured by a support of the pipe in the area of the under side of the roof cover plate (1). The pipe is formed in two parts between which a coupling point is provided so that a tensioning of the superimposed position of the hood and the dome can be achieved. The support is obtained by a collar (K) of the one pipe part (2') which supports against the underside of the dome (4).

Description

The invention relates to a roof covering plate with a roof lead-through in the form of a tube which can be tilted and extends from the underside of the roof covering plate to above it, in that the appropriately dimensioned passage hole is provided in the apex region of a dome with a dome-shaped upper side and the tube is assigned a shape-fitting hood part. wherein the superposition of the hood part on the dome is secured by a provided in the area of the underside of the roof covering plate of the tube to the roof covering plate, and wherein the tube is designed in two parts with a coupling point of both parts such that a tension of the superposition of the hood part and dome can be achieved is.

A roof covering plate of this type is known from DE-OS 36 43 319.

The two-part construction of the pipe in combination with a usable bracing of the superposition of the hood part and the dome not only replaces additional means defining the inclined position, but also has the benefit of variability, e.g. in the sense of different essays. The support takes place there via the holding ribs defining the tilting joint point of the pipe, which are supported in a respective recess in the roof covering plate.

The object of the invention is to include the joint-forming dome itself in the support or holder that brings about a defined tilting adjustment.

This object is achieved by the invention specified in claim 1.

Further configurations emerge from the subclaims.

As a result of such a configuration, an advantageous development of generic roofing panels is achieved. The course of the dome is now fully included in that the support is achieved by a collar of the one tube part which is supported against the underside of the dome. The supporting and bracing forces act against each other, from the top of the hood, from the collar on the underside of the cathedral. Since a larger area at the dome can be used for support than in the mentioned relatively small storage troughs of the roofing slab, the load is also distributed over a larger area. Higher forces can be used for the bracing. The principle found opens up various structural possibilities: One is that the tubular part having the hood part forms with its upper edge the support edge for a nut designed as a ventilation end piece, which is screwed onto the one inner tubular part, the latter being the one over the jacket wall protruding collar forms. With regard to the ventilation end piece, those with a cap protecting against precipitation or simply in the usual lattice structure can be used. In this regard, too, only a relatively small pipe section is obtained as an end piece for antenna feedthroughs. A mother can be molded at the same time. Moreover, it is sufficient if at least the top of the collar corresponds to the inner contour of the dome, so that a free hand remains with regard to stabilizing measures of such additional components. Then it turns out to be advantageous that the Tube part having a hood part with its upper edge forms the support edge for a step of the one inner tube part, which has the collar in the form of a pushed-on and clamped filler piece below the underside of the dome. Such a filler also has stabilizing advantages. The underfloor area of the dome, which is already sufficient in any case, also permits the formation of a relatively large filler piece. The advantage of this solution is also that the adjustment and detection can be carried out from below, ie from below the roof skin. The holding means are simply realized in such a way that the tensioning of the filler piece is achieved by a ring part which is pushed on and secured against rotation. Classic means can be used to prevent rotation. An advantageous embodiment, however, consists in the formation of the ring part as a nut. It is also within the scope of the invention to design the ring part in the sense of a bayonet lock securing. With regard to the filler, it is sufficient for a full system if this is adapted on the top to the inner contour of the dome. Another advantageous embodiment consists in that the collar is designed as support caps lying in the tilt adjustment plane of the tube and projecting over the outer wall of the inner tube part. It does not need to be a complete semi-spherical or circular support joint, which would have the advantage of being able to be adjusted transversely to the direction of inclination of the roof; rather, with a vertically flattened dome formation, it is sufficient if only sections, that is to say two support caps, are provided. In this sense, and even in an extremely material-saving manner, a solution has been found in which the collar is designed as support webs which lie in the inclination adjustment plane of the tube and project over the jacket wall of the inner tube part is. These can be molded on immediately and enlarged to minimize the specific surface pressure on the support side by having these support webs on the dome side with sliding / support runners. Of course, these are adapted to the inner contour of the dome on the contact side. Another, structurally interesting solution is finally that the collar is formed by an annular shoulder of the inner tube part, on which support flaps of the clamped, dome-bearing roof covering plate lying in the tilting radius find their abutment. The circumferential ring shoulder has the advantage of free rotation angle adjustment, which is not possible with regard to the retaining ribs and bearing recesses in the subject of technology. Finally, it proves to be favorable that the axial bracing is achieved by thread engagement.

The roof covering plate 1, designed as a roof lead-through, is designed in its basic structure like the other roof covering plates, that is to say the so-called roof tiles, in order to fit optically well into the area of a roof.

A pipe, for example used for ventilation, designated in its entirety by 2, crosses a passage sloch 3 of the roof covering plate 1. The latter is located in the apex area of a domed roof 4 that bulges out toward the roof top and is preferably designed as an elongated hole. Said dome 4 is domed in a dome shape both on its upper side and on its lower side. It forms concentric surfaces. The curvature line runs, at least in the direction of inclination of the roofing plate 1, around an axis-forming radius point P, about which axis the pipe 2 tilts. The radius point P (tilting radius) lies at a short distance above the roof covering plate 1 and intersects a longitudinal central axis x-x of the pipe 2. In any case, it lies in the region of the lower edge thereof.

Although the dome 4 could be spherical overall, for example in the manner of a ball joint, in some of the solutions it is drawn in parallel to the longitudinal edge edges of the roofing plate 1, essentially to the extent of the outer diameter of the tube 2, so that one Side walls 4 ′ of the dome 4, which delimit the longitudinal shaft in parallel, nestle against the jacket wall of the tube 2, which is circular in cross section. The shaft ends and the apex area merge into the dome side walls 4 'in a narrow curvature.

The dome-shaped upper side of the dome 4 is overlapped by a hood part 5 which also extends from the tube 2.

The inside of the dome lying on the dome-shaped top is at least designed to fit the shape. The hood part 5 can thus be guided in an articulated manner in the inclination plane and thus adjust the angle of inclination of the pipe to the roof covering plane or vice versa, in accordance with the dimension or length dimension of the through hole 3.

For tight guidance of the pipe 2, the hood part 5 continues on the outside of the roof into a collar 6 adapted to the cross section of the pipe 2. Its upward front edge is cut flat, i.e. it runs perpendicular to the longitudinal central axis x-x of the tube 2.

The tube 2 extending from the underside of the roofing plate 1 to the top of the same is designed in several parts, in particular in two parts. Two-part is understood to mean, on the one hand, an axial addition of tube parts and also a radial addition, that is to say the insertion of tube parts into one another.

The latter embodiment is preferred with regard to the first two exemplary embodiments (FIGS. 1 and 4), the former relates to the last two exemplary embodiments (FIGS. 7 and 13).

In the exemplary embodiments shown, the dome 4 is clamped directly or indirectly between the pipe parts 2 ′, 2 ″ via a thread G. The roof covering plate 1 can thus be clamped and fixed in relation to the vertically oriented pipe 2.

The support acting on the underside of the roof covering plate 1 or the dome 4 is achieved by a collar K.

The collar K sits on the one tube part 2 '. At least the top of this collar K, the inside contour of the dome 4 is correspondingly curved or adapted to the tiltability around the radius point P.

According to the first exemplary embodiment (FIG. 1), the further embodiment looks such that the other tubular part 2 ', which has the hood part 5, forms with its upper edge a supporting edge 7 for a nut 9 designed as a ventilation end piece 8. The latter is screwed onto the one, inner tube part 2 ', that is to say the tube part which forms the collar K, which protrudes over its jacket wall.

The other, outer tube part 2 'can be seen here formed by the extension 6 molded onto the hood part 5.

The contact edge 7 is widened by an outward bend 10 of the pipe end there. It is molded on immediately.

As can be seen in FIG. 1 and in particular also in FIG. 3, an annular gap 11 of at least the height of that on the jacket wall of one tube part remains between the jacket wall of the one inner, continuous tube part 2 'and the corresponding jacket wall of the extension 6 or other tube part 2 " 2 'arranged external thread for the corresponding internal thread of the nut 9. The one, inner tube part 2' can thus be freely inserted from below or the other, outer tube part 2 "can be pushed on from above until said external thread protrudes.

The nut 9 is molded onto the ventilation end piece 8 using the same material. The thread G between the two parts has a stroke-free run, so that the tension is reached safely and adjustably.

The axial clamping clearance is clearly shown in Figure 3. Even if this clamping clearance is exceeded, no stop would take place. Rather, the section of the one pipe 2 ′ carrying the external thread would be visible through the vertical ventilation gaps 12 of the end piece 8. Said ventilation gaps 12 carry laterally outwardly directed slats 13 which, in addition to an aerodynamic advantage, also bring about the grip. The ventilation end piece 8, which is designed like a basket, lies comfortably in the hand when unscrewing or unscrewing.

In the second exemplary embodiment (FIG. 4) there is in principle the same structure, only that the thread G is laid under the “protective roof” of the dome 4 and hood part 5. Using the free space already present in the dome 4, this takes up a collar K in the form of a filler 14. The filler 14 is ring-shaped and is pushed from below onto the jacket wall of the one pipe part 2 'and thus braced below the underside of the dome 4, so that the above-described locking effect is present. The reference numbers are used accordingly. The filler 14 is dome-shaped; its underside is flat.

In the case of a semispherical dome 4, the filler 14 could be implemented as a screw body. Taking into account the more or less laterally flattened shape of the dome 4, an annular part is placed under the filler 14. This is designed as a mother 9 '. The latter has an internal thread, which cooperates with a corresponding external thread on the outer surface of the one tube part 2 '. There is no thread here either axial limit stop provided, so that it comes to the desired clamping effect.

The external thread of the pipe part 2 'is exposed. Accordingly, the above-mentioned annular gap 11 also proves to be useful.

Instead of the nut 9, an outwardly directed annular collar 15 with a step 16 on the underside engages at the upper end of the one, inner tube part 2 'over the support edge 7 of the tube 2 created by the other, outer tube part 2 ". This embodiment is particularly clear from FIG 6. There, the inner corner between the outwardly projecting step 16 and the outer wall of the one, inner tube part 2 'can contribute to centering the double tube with a molded cone 17. The cone 17 tapers downwards.

The ring gap 11 also has an insulating effect if it is of corresponding importance.

The ventilation end piece 8 with ventilation gaps 12 is now molded onto the upper end of one inner tube part 2 '.

In order to avoid larger material accumulations both with respect to the filler 14 and also with regard to the ring part, ie nut 9 ', these parts can form empty spaces 18 and 19 which are open at the bottom. The outer wall of the nut 9 'is preferably grooved longitudinally, in order to increase the grip for carrying out the screw connection or loosening.

Instead of generating the tension of the filler 14 via a thread, the ring part can in principle be bayonet-type be formed and cooperate with appropriately designed means on the pipe side.

If irreversible tension is desired, this can be brought about using a locking mechanism. If clamping lamellae are provided with inclined cutting edges, the bracing can also be adjusted later using the existing screw action.

The top of the filler 14 is adapted to the inner contour of the dome 4 in the sense of a full system and correct guidance.

Instead of forming the collar K, for example, from a full annular calotte body, it suffices for the illustrated, flattened version of the dome 4 that the collar K, as support caps lying in the inclination adjustment plane of the tube 2, projecting over the jacket wall of the one, inner tube part 2 ' is formed. These extend diametrically opposite one another from the tube wall sections in the plane of inclination. This version is not drawn. It can be understood if the dashed, horizontal line between the two laterally projecting collars K is disregarded from FIG.

However, this solution is also understandable in the version drawn as the third exemplary embodiment (FIG. 7). There, the collar K or the collars K are realized as support webs 21 lying in the inclination adjustment plane of the tube 2 and projecting over the jacket wall of the one inner tube part 2 '. Their orientation is shown in FIG. 10. The support webs 21 are provided with sliding / support runners 22 in the area forming the actual support zone or the collar K. It is accordingly the curvature of the inside of the dome 4 extending sections of curvature which, seen in cross section, give the web a T-profile.

This exemplary embodiment (FIG. 7) embodies the coaxial stringing together of the pipe parts 2 'and 2 ", connected via a thread G, which at the same time acts as an axial pipe part coupling. The connection is also achieved here while leaving a clamping clearance, denoted by y. In this embodiment, the nut 9, which is now formed on the other, outer tube part 2 ″, engages the underlying contact edge 7 of the tubular extension 6 of the hood part 5 under engagement with the corresponding external thread of the inner tube part 2 ′. In practice, the local extension 6 forms a third pipe part, designated by 2 "'. The third pipe part 2"' is used to clamp the dome 4 between the hood part 5 and the one inner pipe part 2 'via the collar K. The opening y extends of course in front of both ends of the pipe parts 2 ', 2 ".

As far as the fourth embodiment (FIG. 13) is concerned, the structural conditions are such that the collar K originates from an annular shoulder 23. This is formed on the jacket wall of one, lower tube part 2 '. Its support-active upper side runs horizontally, ie perpendicular to the longitudinal center axis xx of the tube 2. Two lateral support tabs 24 rest on the annular shoulder 23. They extend from the lower edge of the clamped roof covering plate 1 having the dome 4. The edge of the support tab 24 extends in a circle around the tilt or radius point P, so that the same support distance to the horizontal annular shoulder 23 remains in each tilt position that can be reached. In this embodiment, the hood part 5 goes from Tube 2 itself, here from the other, outer tube part 2 "of the tube 2. By screwing the axially oriented tube parts 2 ', 2" into each other, the hood part 5 acts tensioning against the top of the dome. In return, the ring shoulder 23, which moves in the opposite direction due to thread engagement G, moves against the support tabs 24 arranged in pairs, so that the described clamping between the collar K and the hood part 5 is also fulfilled here.

In the last exemplary embodiment, the outer, roof-projecting pipe part merges into a ventilation end piece 8, now also with a grating that detects the pipe cross section. It is secured against rotation itself. The pipe part 2 ', on the other hand, can be freely rotated up to the clamping seat.

Common to all of the exemplary embodiments is the arrangement of a flexible hose 25 on the underside of the tube, fixed by means of a clamp 26.

A seal is useful between the support edge 7 and the annular surface of the overlapping component, whether in the form of lips, a joint-overlapping, that is to say bell-like skirt, or a joint slope sloping outwards and downwards.
