Abstract

A skylight (2) is disclosed, mainly for integration in flat roofs and adapted for either being opened as an arched unit or having an arched, openable skylight element, said skylight (2) comprising a support structure or frame constructed of integrated members (26) of aluminium and plastic that are interconnected by means of mountings (58, 60) of an inorganic material, for example aluminium, and preferably self drilling screws (62), said integrated members comprising profile grooves (36) for fixing sealing strips (40). By means of simple measures a skylight is hereby achieved where the said problems with damage caused by rot and fungi do not occur because, instead of organic material, mainly integrated aluminium/plastic members are used, which members, due to their construction, are sufficiently insulated for complying with applicable thermal transmittance coefficients.

Description

Skylight mainly for integration in flat roof construction

FIELD OF THE INVENTION

The present invention relates to a skylight, mainly for integration in flat roofs and of the type specified in the introduction of claim 1.

BACKGROUND OF THE INVENTION

Skylights for flat roofs, for example in industrial buildings, must comply with certain standards with regard to thermal transmittance coefficients and fire ventilation. A study carried out by the Danish Ministry of Housing and Building shows that only known openable skylights with frames made of wood can comply with the standards required. However, skylights with frames made of wood often have other considerable disadvantages that are due to moisture problems as a consequence of condensate which very often result in serious damage caused by rot and fungi in frames made of organic material, wood.

PURPOSE OF THE INVENTION

It is the purpose of the invention to provide a skylight of the type specified in the introduction and which by means of simple measures can eliminate the said problems of damage caused by rot and fungi.

BRIEF DESCRIPTION OF THE INVENTION

The skylight according to the invention is characterised in that it comprises a support structure or frame constructed of integrated members of aluminium and plastic that are interconnected by means of angle mountings of an inorganic material, for example aluminium, and preferably self drilling screws, said integrated members comprising condensate groove and/or profile groove for fixing sealing strips. By means of simple measures a skylight is hereby achieved where the said problems of damage caused by rot and fungi do not occur because, instead of organic material, mainly integrated aluminium/plastic members are used, which members, due to their construction, are sufficiently insulated for complying with applicable thermal transmittance coefficients.

A skylight accordmg to the invention and having an arched, openable skylight element may suitably be provided in such a way that the arched openable skylight element has a frame element which likewise is constructed of integrated members of aluminium and plastic, of which transverse members have been rolled into an arched form, said skylight element furthermore comprising a rigid frame element which likewise is constructed of integrated members having upper and lower profile grooves for fixing sealing strips, and which are mounted above an opening in the arched non-openable skylight element.

The skylight according to the invention may furthermore advantageously be designed in such a way that said integrated members consist of aluminium members that are interconnected in an insulating manner by means of members of heat-resistant, glass- fibre reinforced polyamide or polyacrylic fibre.

According to the invention it may furthermore be advantageous that the skylight is provided in such a way that, as a unit or as the openable skylight element, it is hinge- connected to a fixed frame at a longitudinal side edge, and at the opposite longitudinal side edge is connected to the fixed frame by means of preferably factory-mounted electrical opening/closing units.

The skylight according to the invention may suitably be provided in such a way that the respective members of aluminium and plastic at occurring perpendicular corner joints are mitre cut and joined by means of hidden angle mountings and self drilling screws. Furthermore, the skylight according to the invention may advantageously be provided in such a way that the respective members of aluminium and plastic at occurring straight joints are joined by means of hidden mountings and self drilling screws.

The skylight 2 shown in Figs. 1A-1E is a prefabricated standard skylight ready for mounting from factory, or which from factory is mounted in large self-supporting roof elements of the type especially used in industrial and commercial buildings

(warehouse and manufacturing buildings) that have flat roofs, and which comprise a large number of skylights of which at least a number furthermore must be capable of being opened for reasons of fire ventilation. For this last-mentioned purpose, the skylight 2 may be factory-mounted with one or more electrical window openers along one of its longitudinal sides opposite to integrated hinges, for example (Fig. 3). The skylight 2 is provided with a skylight band 4 in the form of two convex arched panels 6 of transparent polycarbonate joined over a transverse profile member 8 rolled into an arched form, and by means of an upper connecting strip 10 with sealing strips 12 (Fig. 5).

The skylight or skylight band 14 shown in Figs. 2A-2E is built together of a number of prefabricated skylight elements 16, in the shown example of two gable elements 18 and three skylight band elements 20 and an openable element 22, which on the whole is built up in the same way as the skylight 2. The skylight or skylight band 14 may have any suitable length, for example even up to 100 m, in that it may likewise comprise a large number of openable elements 22.

Fig. 3 shows a predominantly sectional view of a longitudinal side member of an openable skylight 2, which, except for a frame element 24, is constructed of inorganic material, viz. of an integrated member 26 of aluminium and plastic, for example glass- fibre reinforced polyamide or polyacrylic fibre. The integrated profile member 26 consists of an inner profile member 28 of aluminium, an outer profile member 30 of aluminium, and connecting profile members 32 and 34 of plastic. The profile member 28 is provided with an outer holding groove 36 for fixing holding members 38 of a sealing profile 40 comprising a sealing lip 42 abutting against the outer side of the lower connecting profile member 32 of the integrated profile member 26. Between the profile member 30 and the frame element 24 a number of hinges 44 are mounted so that the skylight 2 as a unit can be opened, for example by means of electrical opening units (not shown) mounted from factory at the opposite longitudinal side member of the skylight 2.

Towards the top, the skylight 2 is provided with a skylight band 4 consisting of a transparent sheet 46 of polycarbonate connected with a slanting top side 48 of the profile member 30 by means of a sealing strip 50, a cover section 52, and for example self drilling screws 54. An adjustment lath 56 is placed on the connecting profile 34, said lath consisting of hard foamed plastic (integral foam), against which an end part of an arch-rolled transverse profile member 8 of aluminium abuts.

Figs. 3A and 3B, respectively, show a straight longitudinal joint (Fig. 3A) and a perpendicular corner joint (Fig. 3B) of the integrated member 26, in that a straight joint is effected by inserting straight solid connecting strips 58 and 60 of aluminium in adjoining cavities of the profile member 28 and the profile member 30 respectively upon which final fixation of the joint is effected by means of self drilling screws 62 which are screwed in from the outside. In the case of a perpendicular corner joint (Fig. 3B) adjoining end parts of the integrated member 26 are mitre-cut upon which solid angular connecting corners 64 and 66 are inserted in the adjacent cavities of the profile members 28 and 30 respectively, said connecting corners having the same widths and heights respectively as the connecting strips 58 and 60 upon which final fixation of the corner joints is effected by means of self drilling screws 62 that are screwed in from the outside.

Fig. 4 shows joint details for connection with a skylight 2, cf. Fig. IB, towards a frame

24 at a gable 68. A transverse lath 72 is fastened on top of the integrated member 26 by means of self drilling screws 70, said lath consisting of hard foamed plastic (integral foam), and which at opposite ends supports an arch-rolled transverse profile member 8 of aluminium. An upper skylight band 4 in the form of a curved sheet 46 of polycarbonate is supported by means of the transverse profile member 8 and a gable piece 74 consisting of a relatively thick sheet of polycarbonate or corresponding plastics material that does not need to be transparent because the gable piece 74 preferably is covered by means of a metal sheet 76. The skylight band 4 is connected with the transverse profile member 8 by means of an intermediate sealing strip 50 and a curved, angularly bent cover section 78 connected by means of self drilling screws 54. The skylight band 4 is furthermore connected with the curved upper side edge of the gable piece 74 by means of for example glue, in that suitable sealing strips 50 are placed between this piece and the transverse profile member 8 and the lath 72 respectively.

Fig. 4A shows joint details which in general correspond to Fig. 3A for which reason corresponding reference numbers are used. Fig. 5 has already been described above.

Fig. 6 shows joint details at the hinge side of an openable skylight 22 of a skylight or skylight band 14, cf. Fig. 2C. The openable skylight element 22 is constructed of the integrated member 26, while a frame element 80 for the openable skylight element 22 is constructed of another integrated member 82 consisting of an inner profile member 84 and an outer profile member 86 and which are interconnected by means of connecting profiles 88 and 90 of glass-fibre reinforced polyamide or polyacrylic fibre. A number of hinges 44 are mounted between the profile member 86 of the frame element 80 and the profile member 30 of the openable skylight element 22.

At an upper side, the profile member 86 is provided with a holding groove 36 for holding elements 38 of a sealing strip 40 with a sealing lip 42 that provides sealing against the integrated member 26 and the integrated member 82 respectively. At one of its lower sides, the profile member 86 is provided with a corresponding holding groove 36 for holding elements 92 of a sealing strip 12 that corresponds to the one described in connection with Fig. 5, and which has a number of sealing lips 94 that abut against the outer side of the skylight band element 20. This is provided with an opening 96 which in its longitudinal direction is defined between two relatively flat aluminium members 98, each having a rectangular cross-section, and which in its cross direction is defined between two arch-rolled, relatively broad transverse profile members 100, in that opposite end parts of the members 98 are fastened to the respective transverse profile members 100 that in principle correspond to the arch- rolled transverse profile members 8.

The frame element 80 is built up of two longitudinal straight integrated members 82 that at angular joints are joined with two transverse arch-rolled and integrated members 82 (Fig. 7), said members being mitre-cut and joined by means of relatively high, solid angular aluminium mountings that have been inserted in the respective cavities of the profile members 86 and subsequently fastened by means of self drilling screws that have been screwed in from the outer side of the profile members 86.

Fig. 7 shows joint details at a gable side of an openable skylight element 22, cf. Fig. 2E, in which the same reference numbers are used as above. Fig. 8 shows joint details at a longitudinal side of a skylight or skylight band 14, cf. Fig. 2C in which quite the same joining principle is applied as the one described in connection with Figs. 3A and 3B. The same applies to Fig. 9 which shows joint details at straight joints between integrated members 26 at a skylight according to Figs. 1A-1E and/or a skylight or skylight band 14 according to Figs. 2A-2E respectively.

Finally, Fig. 10 shows a sectional view of joint details in an alternative embodiment of a gable 102 of solid wood or solid inorganic material at a skylight or skylight band 14 according to the invention. Immediately within the gable 102 an arch-rolled transverse profile member 8 is mounted that supports a transverse end part of a skylight band 6 consisting of a curved sheet 46 of transparent polycarbonate and which at the curved top side of the gable 102 is covered by means of an arch-rolled angular section 104 of aluminium.

Finally, with regard to the main aspect of the invention, i.e. to completely avoid inorganic material, it should be stressed that the gables of wood shown on the drawing can with no problem be replaced by an inorganic material, for example suitable sheets of solid o foamed plastic. In order to minimise weight, it will probably be preferable to use gable sheets of hard foamed plastic having a closed cell structure, i.e. so-called integral foam plastic.
