Light roof or similar frame truss and frame profile - Ramverk och ramprofil av ett ljustak eller liknande

The invention relates to a frame grid according to the preamble of claim 1 for light ceilings or the like. The invention further relates to a frame profile for use in the truss structure of skylights, the features of which are set out in the preamble of claim 8.

Frame profiles supporting transparent structures of the light roof, such as glass sheets, are provided with sealing strips of elastic material, such as rubber 10, on which the glass sheets are attached. Both edges of the frame profile are then provided with sealing strips running in the longitudinal direction of the profile on both sides for the glass sheets coming from the profile. In order to ventilate the frame grid inside to remove condensing water and to collect and drain any leakage water that may seep into the frames from the area between the glass plates, the central parts of the profiles are generally provided with leakage grooves running longitudinally and bounding laterally to support the strips.

20 In order to have a network that conducts moisture and possible leakage water well away from the frame structure, the grooves in the different profiles must be in close contact with each other. This is done in practice by passing the end of the leakage water 25 of the cross-section connected to the side of the main profile and supported by the main profile up to the corresponding groove of the main profile through the vertical side edge of this groove on the outer side of the profile. Em. the sealing strip is located on top of this side edge. A notch is then made in the side edge of said groove, the depth of which corresponds to the height of the side edge 30 of the corresponding water groove of the cross-section, whereby the grooves for the sealing strips on the upper surface of the side edges of both the main and cross-profile grooves come to the same height. Making notches in the above places in the main profile is a precision-consuming and time-consuming work step that increases manufacturing costs. Em. the construction 35 also has the disadvantage that the height position of the sealing strips is already precisely predetermined, since the grooves are already formed in the profiles when they are manufactured. In the installation phase, there is no room for modification 2 81424, e.g. if the inner surface of the glass on one side of the frame profile is desired at a different height than on the other side.

In order to avoid notches in the main profile, a grid is disclosed in Finnish Patent Application 852089, in which the side edge of the water groove of the main profile comprises a lower edge part on which the end of the water groove of the cross profile is located. An elastic sealing strip is attached to the lower edge part, the height of which corresponds to the sum height of the edge part of the cross-section and the sealing strip 10 thereon. The upper surfaces of the sealing strips of the interconnected profiles are thus in the same plane, being against a common glass pane. Due to the elasticity of the sealing strips, the sealing becomes non-uniform against the glass pane, because at the edge of the main profile side the sealing strip presses against the glass pane with a weaker force than the lower sealing strip on the edge of the cross profile side. As a result, the height of this edge cannot be increased very much with the sealing strip at the edge of the main profile, if the need so requires.

20 Finnish patent application 871082, on the other hand, discloses a frame grid in which the side edge of the main groove water groove is formed by a vertical, slightly tapering wall, on which a wide support strip is placed, which has the same meaning in avoiding notches as the sealing strip disclosed in the above patent application 852089 25. The support strip is made of rigid material, so it can avoid the above-mentioned disadvantages. However, in order for the support strip not to tilt on this side edge, it must also be supported on the side edge of the condensate groove next to the water groove. In this case, the condensate grooves are covered over the entire length of the support strip 30, which is a disadvantage, especially if the profiles and the glass sheets are in such a position that these grooves are needed to collect the condensate from the adjacent glass sheet. If, on the other hand, in the solution according to the present patent application, it is desired to use only the side edge of the water groove as an attachment point for the support strip 35, then it is necessary to form a "snap connection" in the parts in order to keep the support strip therein.

The invention provides a decisive improvement in the above drawbacks. To achieve this, the frame grid according to the invention is mainly characterized by what is set forth in the characterizing part of claim 1. The frame profile according to the invention is in turn characterized by what is set forth in the characterizing part of claim 8. According to the invention, the raising piece can be placed on an upwardly open groove in the lower edge part of the side edge of the water groove of the main profile, whereby the raising piece and the groove 10 are shaped so that the piece cannot move laterally. Due to this structure, it is not necessary to form fastening parts on the lifting piece, for example, which rest separately on the side edge of the condensate groove. The invention also does not require a "snap connection" because the lower surface of the raised pieces can rest on the side edges of the groove of the lower edge portion 15. By assembling the side edge of the leakage groove of the frame profile from several pieces running in the longitudinal direction of the profile, the point of attachment of the sealing strip at the side edge can always be placed at the desired level. The lower part of the side edge can then be fixedly connected to the bottom 20 of the leakage water groove, and a suitable extension piece of the same material, for example with a groove for a sealing strip, is attached to it. When said frame profile is the main profile, a longitudinal gap can easily be arranged between the raised pieces to be placed on the fixed part, in which the end of the leakage grooves at a corresponding height of the associated cross-section fits, so that the notch does not have to be on the fixed edge.

Some preferred embodiments of the invention are set out in the appended subclaims. The raised piece to be placed on the fixed edge part can also consist of two or more overlapping pieces. In addition, other members may be connected to the riser, such as a side-facing trough which can be brought into contact with the end of the condensate trough lower in the cross-section.

The invention will now be described in more detail with reference to the accompanying drawings, in which Figure 1 shows the position of the frame profiles shown in Figure 2 in a skylight structure, Figure 2 shows the junctions of shows an embodiment of a frame profile according to the invention in a cross-sectional view.

The skylight frame grid shown in Figures 1-3 comprises at an angle interconnected frame profiles 1,2,3 located in substantially the same plane and the edges of which are arranged to support and seal roofing sheets made of transparent material, for example glass sheets 4 parallel to said plane. The profiles are metal profiles with a cross-sectional shape that is almost constant over the entire length of the profile. In the connection area of the profiles, the first frame profile 20, e.g. profile 1 in Fig. 2, acts as a main profile supporting a transverse profile 2 associated with it in the plane of the roof structure, e.g. at right angles 2. The end of the transverse profile 2 is then pushed to the edge of the profile 1 will be described in more detail later. Correspondingly, the end of the profile 3 is connected to the edge of the cross-section 2, and at this junction the profile 2 basically acts as profile 1 and profile 3 corresponds to profile 2 associated with profile 1. Of course, several in its longitudinal direction.

Il i s 81424

All profiles have an upwardly open water groove on each side in the longitudinal direction of the profile, denoted by reference numerals 5 (profile 1), 5 '(profile 2) and 5 "(profile 3). The purpose of the grooves has already been described above, and although their main purpose 5 is ventilate the frame grid to drain moisture, they also act as collectors of potential leakage water, which is why they are referred to in this application as leaking water groove or water groove. The water grooves are located in the plane 4 on the outside of the glass edge 4 and bound upwards to the center of the profile. to the strip 17, to which a cover profile 18 is attached in a known manner, which covers the gap between the edges of the glass sheets 4 on opposite sides of the profile formed at the center of the frame profile, sealing the upper surfaces of the glass sheets with Selma. the sleep leakage groove 5, 5 'or 5' 'is limited by an upwardly extending portion 6, 6' or 6 '' from the bottom of the groove, which forms the vertical side edge of the longitudinal groove of the profile piece and which. A sealing strip 8 of elastic material, such as rubber, with a cross-section, e.g. rectangular, is placed on top of the 20, which has a suitably shaped projection on the lower surface, by means of which the sealing strip can be fastened to the upper groove 9 of the part 6, 6 'or 6'1.

According to the invention, the side edge 6 of the frame profile 1 comprises a lower edge part 6a fixedly connected to the bottom of the leakage water groove 5, which continues in a similar cross-section in the longitudinal direction of the profile. The upper surface of the edge portion 6a has an upwardly open groove 10 extending in the longitudinal direction of the profile. On top of the edge portion 6a: 30 movement in the lateral direction, i.e. in the plane direction 35 of the glass sheet 3 perpendicular to its longitudinal direction, is prevented. The extension piece 6b is most preferably made of the same material as the other profile, but it can of course also be of another sufficiently rigid material. The upper surface of the extension piece, in turn, has an upwardly open longitudinal groove 9, which forms the fastening groove described above for placing the sealing strip 8 at the top on the entire side edge 6.

As can be seen from Figures 2 and 3, the sealing strip 9 of the side edge 6 of the main profile 1 and the sealing strip 9 of the respective side edge 6 'of the cross-section 2 are at the same height at the junction (arrow A) of said side edges, so that the same thickness of tape can be used in both profiles. to bring the upper surfaces to exactly the same level.

At the junction of the main profile 1 and the cross-section 2, successively longitudinally raised extension pieces 6b form a gap between which the ends of the leakage grooves 5 'of the cross-section 2 and the side edges delimiting them towards the outer edge 15 can be pushed to the inner edge of the main profile 1 groove 5. The bottoms of the grooves 5 'of said cross-sections are then located on the lower edge part 6a fixedly connected to the main profile 1, resting on it, since this part 6a continues in a continuous position 20 where said gap is left between successively placed raised pieces. Thus, no notches need to be made in the finished frame profile, but this joint can be easily formed during the installation phase by installing the extension pieces in place.

The extension piece 6b of the main profile 1 of Figures 2 and 3 is formed by two overlapping 'U-shaped profile pieces with a wide cross-section'. The bottom of the lower body 6d has a protrusion 11 described above, by means of which the body can be inserted directly from above into the groove 10 of the fixed lower edge part 6a, and the U-shape of the body 30 forms a groove into which the projection at the bottom of the upper body 6e can be inserted from above. on the upper surface of this upper body 6e there is a groove 9 for the sealing strip 8 formed by the U-shape of the body, already described above. The edge 6 'of the side groove 5' of the water groove 5 'of the cross profile 2 in turn consists of a lower, fixed groove 5'

II

7 81424 of an edge portion 6a associated with the bottom and an elevating body 6c formed thereon of a single unit placed thereon, with sauna members as in the elevating body 6b of the main profile 1. The bottom of the lower edge part 6a 5 of the cross profile 2 is located in the plant area of the profiles just above the corresponding edge part 6a of the main profile 1 and its height is equal to the height of the lower body 6d of the main profile extension piece 6b. It automatically follows that when arranging all the extension pieces or parts of the extension piece 6c, 6d, 6e to the same height, they can be superimposed on the desired number and this always ensures that the uppermost sealing grooves 9 come to the same height, because the extension pieces or their parts associated profiles at the corner of the glass plate are always located at the same point in the height direction.

As can be seen from Figures 2 and 3, the individual pieces of extension pieces can also be dimensioned to be of equal width, and the lower fixed edge portions in the different profiles can also be dimensioned as wide with each other and as wide as the above fixed edge portions, so that the pieces fit to different profiles and can be formed sturdy vertical side edge for leaking water groove. This width is preferably equal to the width of the sealing strip 8, whereby the side surfaces of the sealing strips also form a straight vertical extension of the walls of said side edge. The groove 10 in the upper surface of the lower fixed edge portion 6a can also have a cross-section similar to the sealing strip groove 9, in which case a sealing strip 8 can also be attached to it if necessary.

It should be noted that the lower edge part 6a does not have to be completely fixed to the bottom of the groove 5, 5 'or 5' ', but e.g. its upper part may comprise a separate piece like a extension piece extending at the junction of the cross profile and over which the actual extension piece and profile water groove end are located.

The invention has been described above mainly with reference to the joint of profiles 1 and 2 35. It should be noted, however, that a similar idea has been implemented at the junction of profiles 2 and 3 s 81424. At this point, the profile 2 acts as a main profile and the profile 3 as a cross-section, and on one of the fixed lower edge portions 6a of the water groove 5 'of the main profile 2 a one-piece raised piece 6c is placed, the height of which corresponds to the side edge 6'1 of the water profile 5'1 of the cross-section. The bottoms of the water grooves 5 '* and the side edges 6' 'are similarly at this joint point on the fixed edge part 6a of the main profile 2 and the sealing strips 8 of the interconnected profiles 2 and 3 10 are cast at the same height. Figure 2 also shows how, by means of the invention, different water grooves 5, 5 ', 5'1 can be easily brought to different levels, while the sealing strips 8 remain at the same level. This is particularly helpful in draining water and ventilating the frame structure in the event that the main profiles are associated with cross-sections, which in turn are associated with cross-sections, etc. This situation is often encountered when dividing larger glass panes into smaller ones as shown in Figure 1.

Figure 4 shows an advantage of the extension pieces 20 according to the invention. The outermost frame profiles have condensate grooves 13 (profile 1), 13 '(profile 2) and 13' '(profile 3) on both sides, which are also connected to each other in the same way as the leakage grooves 5, 5' and 5 '* located in each profile so that the side edges delimiting them on the outer edge side are lower than the side edge of the leakage groove in the same profile and extend laterally to below the glass plate. The condensate grooves are thus able to collect water condensing on the inner surface of the glasses and lead it away from the frame structure. The width of the grooves is in some cases not sufficient due to, for example, the angle with respect to the horizontal plane where the glass sheets and cross-sections are with respect to the main profile. The main profile frame profile 1 according to Fig. 4 has a longitudinally extending condensate gutter 12 projecting laterally on the profile of the profile, which extends laterally wider than the actual the end of the respective condensate chute 13 'is above the chute 12 of the raising piece 6b and its bottom rests on the outer side edge 16 of the chute 12. Correspondingly, the bottom of the trough 12 rests on the outer side edge 14 of the condensate trough 13 5 of the main profile 1.

Figure 4 also shows how the height position of the sealing strips 8 can be desired in the original profile according to a certain standard with the extension pieces according to the invention, e.g. so that on one side of the profile the tii-10 sealing strip is located at a lower level than on the other side. For example, in the case of Figure 4, if it is desired to place a thicker glass sheet on one side (triple glass on the right side in the figure) than on the other side (double glazing on the left), sealing strips can be placed at the desired heights so that the top surfaces of the glass sheets are flush.

It is clear that the design of the various parts may vary within the scope of the inventive idea set out in the claims. The extension pieces or parts thereof are preferably of standard height and width, e.g. a height of 6 mm and a width of 13 mm raising the side edge 6, 20 6 'or 6 * * of the U-shaped part, but of course correctly sized pieces can always be made depending on the application. The extension pieces can also be fastened to each other in other ways than described above. The fixed lower edge portions 6a in the profiles as well as the raised pieces to be placed on them 25 can have a very wide cross-section. From the point of view of the fit of the parts, it is advantageous that their cross-sections comprise mutually compatible shapes which hold the parts together so that the parts remain on top of each other without moving laterally with respect to each other. The parts are tightly joined together when the glass sheets are inserted. The glass sheets then press the extension pieces against the lower edge portions.

In the pictures, all the glass sheets at profiles 1, 2 and 3 are located on the same level, while the profiles are also located in the sauna Tasos-35 sa. However, it is possible that the planes and profiles of the glass sheets are located at an angle to each other. Also in this case, the extension pieces according to the invention can be used in exactly the same way. It should also be noted that the terms "top", "bottom", "side" and the like in this application refer to a position relative to the plane of the glass sheet at the edge of the profile in question, i.e. "down" means facing the interior bounded by the roof, etc. with respect to the ground may be very steep, and the term "light ceiling" in this context should be understood quite broadly and also means 10 facade structures using the frame profiles described above.

The frame profiles described above, as well as the extension pieces to be attached to them, are most preferably made of aluminum by extrusion.
