OPFINDELSENS OMRÅDEFIELD OF THE INVENTION

Den foreliggende opfindelse angår et beslagsystem til montering af vindue og af den i indledningen til krav 1 angivne art.The present invention relates to a mounting system for window mounting and of the kind specified in the preamble of claim 1.

5 OPFINDELSENS BAGGRUNDBACKGROUND OF THE INVENTION

Ved montering af vinduer i moderne byggeri med bagmur eller -væg er det et voksende problem at fastgøre vinduer, døre og tilsvarende bygningsdele, som er placeret i ydermur eller -væg på grund af den meget kraftigt isolerede hulmur, hvilket i praksis vil sige det relativt brede hulrum imellem indermur og ydermur. Selvom vinduer, døre 10 og tilsvarende bygningsdele er placeret i ydermur eller -væg, er det oftest et myndighedskrav, at de pågældende bygningsdele skal være fastgjort til inder- eller bagmur på en sådan måde, at der i mindst muligt omfang forekommer kuldebroer.When installing windows in modern building with a back wall or wall, it is a growing problem to fix windows, doors and similar building parts which are located in the outer wall or wall due to the very strongly insulated cavity wall, which in practice means relatively wide cavities between inner wall and outer wall. Although windows, doors 10 and similar building elements are located in exterior walls or walls, it is most often a requirement of the authorities that the building elements in question must be fixed to the inner or back wall in such a way that cold bridges occur to the minimum extent possible.

DE-A1-28 50 163 beskriver en laske til en vinduesramme, hvor lasken har huller til 15 optagelse af et fastgørelseselement med pigge og to fremspring, således at lasken kan fastgøres til rammen med fastgørelseselementet, der kan placeres i et af hullerne. Lasken har bl.a. et hul med to spor placeret overfor hinanden i den ene ende af lasken, hvor et fastgørelseselement med en låsefunktion kan placeres.DE-A1-28 50 163 discloses a window frame latch, wherein the latch has holes for receiving a fastener with spikes and two projections, so that the latch can be attached to the frame with the latch element which can be placed in one of the holes. The bottle has a hole with two grooves positioned opposite each other at one end of the lug where a fastener with a locking function can be placed.

20 OPFINDELSENS FORMÅLOBJECTS OF THE INVENTION

På denne baggrund er det formålet med opfindelsen at angive et forbedret beslagsystem af den indledningsvis nævnte art, og som ved hjælp af enkle foranstaltninger gør det muligt at opnå en betydelig forbedring ved montering af vinduer, døre og tilsvarende bygningsdele i afstand ud for muråbninger i moderne byggeri med indermur af 25 beton, kraftig isoleret hulmur og ydermur eller -væg.In the light of the foregoing, it is an object of the invention to provide an improved bracket system of the kind mentioned above, which, by means of simple measures, makes it possible to achieve a considerable improvement in the installation of windows, doors and similar building components at a distance from wall openings in modern building with 25 concrete inner wall, strong insulated cavity wall and outer wall or wall.

KORT BESKRIVELSE AF OPFINDELSENBRIEF DESCRIPTION OF THE INVENTION

Beslagsystemet ifølge opfindelsen er kendetegnet ved, at nævnte beslagdele udgøres af et antal beslagdele med endedele, der er indrettet til at fastgøres i en nedre henholdsvis 30 en øvre vandret side af muråbningen ved hjælp af betonskruer, og med en endedel, der er indrettet til at fastgøres til en underside henholdsvis en overside af nævnte vindueseller dørkarm, samt af et antal sidebeslag, der er indrettet til at fastgøres dels til lodret- 2 DK 176333 B1 te sider af muråbningen og dels til lodrette ydersider af nævnte vindues- eller dørkarm, idet mindst et sidebeslag ved hver sin side af nævnte vindues- eller dørkarm udgør et skråtstillet bærebeslag, hvis ene, øvre endedel er indrettet til at fastgøres til en sidekant af muråbningen, og hvis modsatte, nedre endedel er indrettet til at fastgøres til ydersi-5 der af nævnte vindues- eller dørkarm i et fælles punkt med sidebeslag. Ved hjælp af enkle foranstaltninger bliver det herved muligt at opnå en forenkling og en forbedring ved montering af vinduer, døre og tilsvarende bygningsdele i moderne byggeri med meget kraftigt isolerede hulmure.The bracket system according to the invention is characterized in that said bracket parts are constituted by a number of bracket parts with end parts arranged to be secured to a lower and an upper horizontal side of the wall opening, respectively, by means of concrete screws, and with an end part arranged to is fixed to an underside and an upper side respectively of said window or door frame, and of a number of side fittings arranged to be fixed partly to vertical sides of the wall opening and partly to vertical exteriors of said window or door frame, at least a side bracket at each side of said window or door frame constitutes an oblique support bracket whose upper end portion is arranged to be attached to a side edge of the wall opening and the opposite lower end portion is arranged to be secured to exteriors of said window or door frame in a common point with side fittings. With the help of simple measures, it will be possible to achieve a simplification and improvement in the installation of windows, doors and similar building elements in modern construction with very strongly insulated cavity walls.

10 Det har desuden vist sig, at beslagsystemet ifølge opfindelsen samtidigt løser de problemer, som byggesagkyndige har fremført imod at fastgøre vinduer, døre og tilsvarende bygningsdele til den udvendige betonplade af betonsandwichelementer, fordi der herved på grund af store temperatursvingninger i den udvendige betonplade vil forekomme revner indvendig ved lysning/dampspærre og vindue.Furthermore, it has been found that the bracket system according to the invention simultaneously solves the problems that construction experts have raised against attaching windows, doors and similar building parts to the exterior concrete slab of concrete sandwich elements, because of this, due to large temperature fluctuations in the exterior concrete slab will occur. cracks inside at lightening / vapor barrier and window.
