Description

Device for leading a pipe having a large cross section through a roof
This invention relates to a device for leading a pipe having a large cross section through a roof.
In connection with such devices water leakages have usually been attempted to prevent by means of metal sheet cladding made by a sheetmetal worker. The work is espensive, and today only few skilled sheetmetal workers are available. Instructions for sheet metal cladding are given in the RT-card index referred to by designers in their work specifications. Such cladding applications are associated with difficult corner areas having the risk of leakage. Today metal sheets are delivered prepainted and are thus susceptible to be scratched during their installation. A further difficulty is that pipes or chimmeys are led through a roof vertically and horizontally at a random site which hampers obtaining a sufficient tightness on tile and profiled sheet roofs.
The object of the present invention is to provide a device for leading a pipe through a roof which is easily mountable and which can be manufactured at lower costs, whereby the risk of a water leakage has been eliminated and which is easily adaptable according to the position of the device both to felt roofs and metal sheet and tile roofs. This aim can be obtained by a device for leading a pipe through a roof which is characterized in that it comprises a leading-through body made of plastic, having an upwardly tapering collar and a substantially rectangular flange extending evenly from the lower edge of the collar, whereby said flange is provided with a radially open recess extending circumferentially around the whole flange, said recess being defined from above by an upper flange and from below by a lower flange.
Preferably, the lower flange extends radially considerably father outward than the upper flange, which gives a better support to the leading-through body and is advantageous especially when mounted to a felt roof. Thereby, after an underlaying felt has been installed, the leading-through body is adapted to an opening formed in the roof so that the lower flange lies on the underlying felt. Fastening to the roof may be carried out, for instance, by means of felt nails, for which propose the lower flange may be provided with previously prepared nail holes. An overlying felt has been cut and installed to allow the edges facing the flange to extend right to the bottom of the recess between the lower flange and the upper flange, whereby for ensuring sealing, bitumen adhesive is applied onto the upper surface of the lower flange and onto the lower surface of the Upper flange before the overlying felt is installed.
For installing onto a metal sheet roof or a tile roof, two covering panels can be inserted from opposite sides into the recess surrounding the flange, and adhered thereto, for which purpose a rectangular opening has been cut in that edge of each of the covering panels which faces to the leading-through body, said openings being dimensioned to allow their edges to fit into the recess surrounding the flange, and positioned so, that, in assembled condition, the edges of the covering panels facing each other overlap one another, and the side edges of the covering panels will lie in the valleys of the corrugation of the profiled roofing material, while the upper edge of the covering panels extending under a ridge sheet or a ridge tile. Gluing of the covering panels to the recess of the leading-through body is preferably carried out by means of silicone adhesive so that the recess is filled with said silicone adhesive before the covering panels are inserted into the recess to obtain a strong and waterproof joint.
The cross section of the collar of the leading-through body may be either quadrangular or annular depending on the shape of the pipe or the chimney led through the roof. Similary shaped covering panels are suitable for the leading-through body regardless of the shape of the collar thereof.
Preferably, in the transition region between the collar and the flange a recess surrounding the flange has been formed which deepens linearly from that end of the leading-through body facing the eaves towards its end facing the ridge. Due to the upwardly tapering shape of the collar and due to said recess, the device for leading a pipe through a roof according to the invention can be mounted to roofs, the inclination of which may be between 0 and 45 °.
According to one embodiment, the covering panels are designed so that one panel is intended to be inserted into the recess provided in the flange of the leading-through body from the side facing the ridge of the roof, and the other from the side facing the eaves of the roof. For ensuring tightness, said rectangular opening in the ridge side covering panel has a depth which allows, in the installed position, the upper edge of said covering panel to lie under a ridge sheet or a ridge tile, and the eaves side covering panel is provided with a corresponding rectangular opening having a depth allowing the upper edge of this covering panel to lie overlapping under the lower edge of the ridge side covering panel, whereby said rectangular openings are cut in such a position which allows the side edges of the covering panels to lie in the corrugation valleys of the profiled roofing material.
According to another embodiment of the invention, the covering panels are designed to be inserted into the recess provided in the flange from the opposite lateral sides of the leading- through body. In this case each of the covering panels is provided with a rectangular opening, having a depth which allows the opposite edge regions of the ridge side parts and the eaves side parts of the covering panels to overlap one another, and the side edges of the covering panels to be positioned in the corrugation valleys of a profiled roofing material, whereby said openings are positioned so that, in assembled condition, that end of each of the covering panels which faces the ridge, extends under a ridge sheet or a ridge tile.
Instead of the arrangement that the covering panels inserted from the opposite sides into the recess surrounding the flange of the leading-through body always have to extend under the ridge sheet or the ridge tile, according to a preferred embodiment a third covering panel has been installed on the side of the leading-through body facing the ridge, whereby that edge of the covering panel which faces the leading-through body is provided with a lower flange which can be inserted into the recess provided in the flange of the leading-through body, and a longer upper flange extending over the upper flange provided in the edge of the flange of the leading-through body, whereby the length of the third covering panel can be dimensioned to allow its upper edge to extend under the ridge sheet or the ridge tile, the side edges of which being provided with downwardly facing folds which end ahead from the edge region provided with flanges. All joints between the covering panels and the leading-through body as well as between different covering panels are glued with silicone paste.
The width of the third covering panel is adaptable to the common width of both other covering panels which have been inserted from the opposite sides of the leading-through body into the recess provided in the flange of the leading-through body, by cutting said third covering panel to a right width, and by placing the edge part, which has been cut of and from which the edge region provided with flanges has been removed, under the cut edge of said covering panel, whereby the joints are adhered with silocone paste. This solution enables to adapt all covering panels so that their side edges are always situated in a desired position in the corrugation valleys of the roofing material, while the flanges in the lower edge of the third covering panel ensure a reliably sealed construction, when silicone paste is applied also onto the underside of the upper flange of the third covering panel before said covering panel is installed, and the gap between the side covering panels and the upper flange of the upper third covering panel and the gap between the flanges of the upper covering panel are filled with silicone paste.
When the device for leading a pipe through a roof according to the invention is intended to be installed on a roof consisting of planar metal sheets arranged in rows, for fastening the leading-through body and the covering panels to the roof, two fastening bars are arranged, having a height corresponding to the height of each of the upwardly extending joint edges of said roofing, said fastening bars extending on both sides of the leading-through body (1 ) from below the flange of it up to the ridge of the roof.
The leading-through body belonging to the invention is suitable to be mounted to roofing materials of all kinds. Only the outer edges of the covering panels are shaped slightly differently for different roofing materials in order to be adapted to the contour of the roofing material in question.
Preferably, the outer edges of the lateral and the eaves side covering panels are provided with foamed plastic sealings supported against the roofing material which effectively prevent water from entering under the covering panels.
A further advantage of the present invention is that it is independent of the position of the leading-through body on the roof, because the covering panels are intended to be delivered without openings together with the leading-through body, and therefore no measurements carried out in advance are necessary. The position of the rectangular openings to be cut in the covering panels is measured on the roof, and the cutting is preferably carried out by means of a pattern in order to adapt the width of said opening to conform to the recess provided in the flange of the leading-through body, whereby in determination of the depth of the openings, the overlapping arrangement of the covering panels has been considered. In the following the invention is described in more detail referring to the enclosed drawing wherein Fig. 1 shows side sectional view of a device for leading a pipe through a roof, mounted on a profiled metal sheet roof;

Fig. 12 shows a perspective view of a third covering panel used in the fourth example, upside down:
Fig. 13 shows how fastening bars are to be mounted to a roofing made of metal sheets arranged in rows for fastening the device for leading a pipe through a roof. The device for leading a pipe having a large cross section through a roof shown in figure 1 comprises a leading-through body 1, having an upwardly tapering collar 2 which is slidable over a pipe 3 led through the roof. The cross-section of the collar 2 may be rectangular, as shown in figures 2 to 6, or annular, as shown in figures 7 to 9. The lower edge of the collar 2 comprises an evenly extending flange 4, the outer end of which being provided with a radially open recess 5 extending circumferentially around the whole flange, more clearly apparent from figures 4 to 5 a. From above the recess 5 is defined by an upper flange 4a and from below by a lower flange 4b. Two covering panels 6a and 6b are inserted into this recess 5 from the opposite sides and adhered thereto with silicone adhesive or a correspondig joining paste 7. In the edges of both covering panels 6a, 6b facing to each other and to the leading-through body 1 , a rectangular opening 8a, 8b is cut, said openings being dimensioned so that their edges fit into the recess 5 surrounding the flange 4 and that, in assembled condition, the edges of the covering panels 6a, 6b facing to one another overlap each other. Preferably, in the transition region between the collar 2 and the flange 4 of the leading- through body 1 , a recess 9 encircling the collar 2 has been formed which deepens linearly from the end of the leading-through body facing to the eaves towards the end thereof facing to the ridge of the roof. In figures 2 and 3, the covering panel 6a is intended to be mounted to the leading-through body 1 from the side facing to the ridge of the roof, and the covering panel 6b from the side facing to the eaves, whereby in the overlapping edge region of the panels, the covering panel 6a lies on the covering panel 6b, as can be seen clearly from figure 3. The rect- angular opening 8a cut in the ridge side covering panel 6a is situated in such a position that, in assembled condition, the upper edge of the covering panel 6a extends under a ridge sheet 10 preventing thus any water leakage from the side of the ridge 10. The rectangular opening 8b cut in the eaves side covering panel 6b has a depth which, in assembled condition, allows the upper edge of this covering panel 6b to lie overlapping under the lower edge of the covering panel 6a.
In the embodiment shown in figure 6, covering panels 6a and 6b are used which are inserted into the recess 5 in the flange 4 of the leading-through body 1 from two side directions. The covering panels 6a, 6b are thus mirror images of one another. Each of the covering panels 6a, 6b has such a rectangular opening 8a, 8b, having a depth, due to which the opposite ridge side and eaves side edge regions overlap one another, whereby the openings 8a, 8b are arranged in such a position that, in assembled condition, that the end of each of the covering panels 6a, 6b which faces to the ridge of the roof extends under a ridge sheet 10 or ridge tile. At the end of each of the covering panels 6a, 6b facing to the eaves an end piece 11, optionally of foam plastic, is arranged, being shaped to conform to the profile of the roofing material. Also a sealing strip conforming to the profile of the roofing material may be arranged to extend along the side edges of the covering panels 6a, 6b. Figure 7 shows a device for leading an annular pipe having a large cross section through a roof. A leading-through body 1 is similar to that illustrated in the preceding figures, except for that the collar 2 thereof has an annular cross-section. The construction of the covering panels 6a, 6b of the device for leading a pipe through a roof is similar to that demonstrated in figure 3.
In the embodiment shown in figure 8, covering panels 6a, 6b of the type of figure 6 are inserted into the recess 5 in the flange of the leading-through body 1. The side edges of the covering panels 6a, 6b have a downwardly extending fold, the inside of which being optionally provided with a foam plastic seal. The part of the covering panel 6a (figures 2,3 and 7) or the covering panels 6a, 6b (figures 6 and 8) at the ridge side of the leading through body, may be slightly folded downwards so that the upper edge extending under a rigde sheet 10 is in its whole width in contact with the roofing material or the corrugation ribs of the roofing material.
It is intended that the leading-through body 1 made of plastic, and the separate covering panels 6a, 6b, which have not yet been provided with openings 8a, 8b, as well as silicone adhesive, are delivered to a house builder who cuts a rectangular opening 8 a, 8b in the right site of the covering panels 6a, 6b by means of a pattern, after having first measured the distance of the leading-through body 1 from the ridge of the roof.
In the embodiment shown in figures 9 and 10 in which the leading-through body 1 has been mounted on a felt roof, the lower flange 4b of the leading-through body extends radially considerably farther than the upper flange 4a which ensures the leading-through body 1 a solid support against the roof. After the installation of the underlying felt 11a, the leading-through body 1 has been adapted to. an opening formed in the roof so that the lower flange 4b lies on the underlying felt 1 la, whereby fastening to the roof is preferably carried out by means of felt nails 12, for which purpose along the edge of the lower flange 4b nail holes 4c are pre-provided. An overlying felt l ib has been cut and installed so that the edges thereof facing to the flange 4 extend quite to the bottom of the recess 5 between the lower flange 4b and upper flange 4a, whereby in order to ensure sealing, bitumen adhesive has been applied onto the upper surface of the lower flange 4b and onto lower surface of the upper flange 4a before installation of the overlying felt 1 lb.
Figure 11 shows an example of a forth embodiment of the device according to the invention for leading a pipe through a roof. According to this embodiment, a third covering panel 6c has been mounted on that side of the leading-through body 1 which faces to the ridge of the roof, whereby the edge of said third covering panel 6c facing to the leading-through body 1 is provided with a lower flange 12a insertable into the recess 5 arranged in the flange 4 of the leading-through body as well as with a longer upper flange 12b (figure 12) extending over the upper flange 4a provided in the edge of the flange 4 of the leading-through body 1 (figure 12). The length of the covering panel 6a is adaptable so that its upper edge extends under the ridge sheet 10 or the ridge tile, and its side edges have downwards extending folds 14 which end ahead of the edge region provided with the flanges 12a, 12b. When the device according to the invention for leading a pipe through a roof is intended to be mounted on a roof made of planar metal sheets arranged in rows, for fastening the leading- through body 1 and the.covering panels 6a, 6b to the roof, two fastening bars 14 having a height corresponding to the heigth of each of the upwards extending joint edges of the roof, said fastening bars extending on both sides of the leading-through body from below the flange 4 of it up to the ridge 10 of the roof, as can be seen from figure 13. The width of the covering panel 6c is adaptable to the common width of both other covering panels 6a, 6b which have been inserted from the opposite sides of the leading- through body 1 into the recess 5 provided in the flange 4 thereof, by cutting said covering panel 6c to a proper width and by placing the edge part cut off, after the edge region provided with the flanges 12a, 12b have been removed, under the cut edge of the cut covering panel 6c, whereby the joints are sealed with silicone paste. In this way also the width of the third covering panel 6c can be adapted to the corrugation valleys, when the device for leading a pipe through a roof have been mounted on a corrugated roofing material.
