Description

DK 155683 BDK 155683 B

iin

Opfindelsen vedrører lyddæmpende døre og specielt døre af den type, der benævnes "dobbeltkonstruktion uden mekaniske forbindelser".The invention relates to sound attenuating doors and especially doors of the type referred to as "double construction without mechanical connections".

Når fyldingen i en dør af denne art udføres 5 som en lamelkonstruktion, eksempelvis ifølge svensk fremlæggelsesskrift 330 250, med lameller af eksempelvis træfibermateriale, opnås en konstruktion, der kan absorbere laterale resonanser.When the filling in a door of this kind is carried out as a slat structure, for example according to Swedish presentation specification 330 250, with slats of, for example, wood fiber material, a structure is obtained which can absorb lateral resonances.

Et yderligere skridt mod forbedret lyddæmp-10 ning opnås, dersom den kendte dør arrangeres med en delt ramme, eksempelvis ifølge svensk fremlæggelsesskrift 349 093.A further step towards improved sound attenuation is achieved if the known door is arranged with a split frame, for example according to Swedish presentation specification 349 093.

Den kendte teknik anviser imidlertid ikke en optimal løsning på lyddæmpningsproblemet ved en vis 15 tilgængelig materialekombination og materialevægt.However, the prior art does not provide an optimal solution to the sound attenuation problem of some available material combination and material weight.

Sigtet med den foreliggende opfindelse er derfor at anvise en sådan løsning under samtidigt hensyn til praktisk og økonomisk realiserbare fremstillingsmuligheder .The object of the present invention is therefore to provide such a solution while simultaneously considering practical and economically feasible manufacturing possibilities.

20 I henhold hertil anviser opfindelsen i sit bredeste aspekt en dør omfattende en rammekonstruktion og en fyldingskonstruktion, i hvilken der indgår et lamelarrangement, samt på begge sider af ramme og fylding anbragte dæklag, og det særlige ved 25 døren er, at lamellerne i fyldingen ligger hovedsagelig tæt mod hinanden og er diskontinuerlige i deres lamgderetning, i det mindste over den største del af deres tværsnit.Accordingly, in its broadest aspect, the invention discloses a door comprising a frame structure and a filling structure incorporating a slat arrangement, as well as cover layers arranged on both sides of the frame and filling, and the special feature of the door is that the slats in the filling lie mostly close to each other and are discontinuous in their lambing direction, at least over most of their cross-section.

Lamellerne kan principielt strække sig enten 30 i dørens højderetning eller i dens bredderetning.The slats can in principle extend either 30 in the height direction of the door or in the width direction thereof.

De efter hinanden følgende lameller består fortrinsvis skiftevis af porøst og hårdt materiale, eksempelvis træfibermateriale.The successive slats preferably consist alternately of porous and hard material, for example wood fiber material.

DK 155683 BDK 155683 B

2 Dørens fylding udgøres hensigtsmæssigt i princippet af en såkaldt dobbeltkonstruktion uden mekaniske forbindelser (til forskel fra hvad der inden for faget kendes som "massiv dør"), i hvilket tilfælde 5 lamelarrangementet kan være fordoblet med hvert sæt lameller fæstnet til et bærende underlag.2 The filling of the door is conveniently constituted in principle by a so-called double construction without mechanical connections (as opposed to what is known in the art as "solid door"), in which case the slat arrangement can be doubled with each set of slats attached to a supporting substrate.

Det bærende underlag indgår fortrinsvis i det af et par plader, eksempelvis plader af hårdt træfibermateriale, bestående dæklagsarrangement.The supporting substrate preferably forms part of the covering layer arrangement of a pair of sheets, for example sheets of hard wood fiber material.

10 Diskontinuiteterne i lamellerne kan hensigts mæssigt være udført i form af savspor eller lignende afbrydelser, der udgår fra den bort fra det bærende underlag vendende side af lamellerne, og gennemskærer den største del af lamellerne.Conveniently, the discontinuities in the slats may be formed in the form of saw grooves or similar interruptions, starting from the side facing away from the supporting surface of the slats, and intersecting the greater part of the slats.

15 De ved savningen fremkomne lamelstykker har i hovedsagen ens længde, og denne længde bør være mindre end den dobbelte lamelhøjde (højden målt vinkelret på dørfladens plan).15 The slats produced by the saw are generally of the same length and this length should be less than the double slab height (the height measured perpendicular to the plane of the door surface).

Opfindelsen anviser tillige en fremgangsmåde 20 ved fremstilling af den omhandlede dør. I en første variant af denne fremgangsmåde fremstilles dørfyldingen ved, at mindst ét sæt lameller lægges hovedsagelig tæt mod hinanden på et underlag og fæstnes til dette, hvorefter lamelsamlingen på ønsket måde gennem-25 saves ved hjælp af en lamelsav eller et tilsvarende redskab til dannelse af de nævnte diskontinuiteter.The invention also discloses a method 20 in the manufacture of the present door. In a first variant of this method, the door filling is prepared by laying at least one set of slats substantially close to one another on a substrate and adhering thereto, after which the slat assembly is desirably screened by means of a slat saw or similar tool to form the mentioned discontinuities.

I en anden variant gennemsaves dørens ramme, fortrinsvis i planet for eksisterende tætningslistespor, til en såkaldt dobbeltkonstruktion uden meka-30 niske forbindelser, hvorefter lamelsættene i hver dørhalvdel gennemsaves med en lamelsav eller et lignende redskab.In another variant, the door frame, preferably in the plane of existing sealing groove grooves, is pierced to a so-called double construction without mechanical connections, after which the slat sets in each door half are pierced with a slat saw or similar tool.

Opfindelsen er i det følgende nærmere forklaret ved nogle eksempler under henvisning til tegningen, på hvilken fig. 1 viser et perspektivbillede af en dør-5 fylding eller en sektion til en sådan fylding, fig. 2 et brudt, lodret snit i en dør med en fylding ifølge fig. 1, fig. 3 et skematisk og delvis afbrudt billede til illustrering af fremgangsmåden ved fremstilling af 10 en fyldingssektion til en dobbeltkonstruktion, og fig. 4 en del af et snit som viser, hvorledes fyldingen ifølge fig. 3 kan anbringes i en ramme, hvorhos det tillige er antydet, hvorledes en "dobbeltkonstruktion" hensigtsmæssigt kan gennemsaves.The invention is explained in more detail below by some examples with reference to the drawing, in which: FIG. 1 is a perspective view of a door-filling or section for such filling; FIG. 2 shows a broken vertical section of a door with a filling according to FIG. 1, FIG. Fig. 3 is a schematic and partially broken view illustrating the method of making 10 a double section filling section; 4 is a sectional view showing how the filling of FIG. 3 can be placed in a frame, as is also indicated, how a "double structure" can be conveniently pierced.

15 Fig. 1 viser i delvis afbrudt perspektivbille de en dørfylding 10, der i den viste udførelsesform er sammensat af to lag 11 og 12. Hvert af disse består af et arrangement af træfiberlameller eller lignende elementer, der er udsavet af træfiberplader, og 20 de efter hinanden følgende lameller, såsom 14 og 13, består skiftevis af porøst og hårdt træfibermateriale . Lamelarrangementerne er centralt adskilt fra hinanden af en plade 15 af eksempelvis hårdt træfibermateriale, men de er ikke fikseret til denne plade, der 25 i og for sig ikke er absolut nødvendig, men giver visse fordele med hensyn til bl.a. brandbeskyttelse og lyddæmpning. På den modsatte side af hvert af lamelarrangementerne findes der dæklag, som hver for sig kan være sammenlimet eller på anden måde sammen-30 føjet af hårde træfiberplader 16, 17 eller lignende materiale.FIG. 1, in partially broken perspective view, they show a door filling 10, which in the illustrated embodiment is composed of two layers 11 and 12. Each of these consists of an arrangement of wood fiber slats or similar elements sawn out of wood fiber boards and 20 consecutive slats, such as 14 and 13, consist alternately of porous and hardwood fiber material. The slat arrangements are centrally separated from one another by a plate 15 of, for example, hard wood fiber material, but they are not fixed to this plate, which in itself is not absolutely necessary. fire protection and muffler. On the opposite side of each of the slat arrangements, there are cover layers which may be individually bonded together or otherwise joined together by hard wood fiber sheets 16, 17 or similar material.

I hvert af lamelarrangementerne 11 og 12 er der dannet afbrydelser, der i den viste udførelsesform udgøres af savspor 21, der fra fyldingen 10's 4In each of the lamellar arrangements 11 and 12, interruptions are formed which in the illustrated embodiment are formed by saw grooves 21 which from the 4 of the filling 10

midterplan strækker sig helt frem til det indvendige dæklag 16: Afbrydelserne eller diskontinuiteterne i lamellerne 13 og. 14 kan imidlertid også tilvejebringes på anden måde, eksempelvis ved at lamellerne kun 5 saves delvis igennem, hvilket kan være at foretrække af håndteringsmæssige hensyn, eller i forvejen afsavede lamelstykker kan lægges tæt mod hinanden og på hensigtsmæssig måde anbringes i dørrammen mellem dækpladerne .center plane extends all the way to the inner cover layer 16: the interruptions or discontinuities of the slats 13 and. However, 14 may also be provided otherwise, for example, by only partially cutting the slats 5, which may be preferable for handling reasons, or pre-cut slats may be placed close to each other and suitably placed in the door frame between the cover plates.

10 Lamellerne 13, 14 er anbragt løst i for hold til hinanden og i forhold til midterpladen 15, men er fæstnede til dæklaget, enten over hele fladen eller kun over en del af denne. De "fri", forholdsvis korte lamelstykker, der opnås på denne måde, 15 giver gennem deres frihedsgrad et uventet stort bidrag til materialets lyddæmpende egenskaber, hvilket bl.a. har betydet, at det for et og samme lydreduktionstal har været muligt at reducere dørens totalvægt i ikke uvæsentligt omfang.The slats 13, 14 are mounted loosely to one another and to the center plate 15, but are attached to the cover layer, either over the entire surface or only over a portion thereof. The "free", relatively short slats obtained in this way, through their degree of freedom, make an unexpectedly large contribution to the sound attenuating properties of the material. has meant that for one and the same noise reduction number it has been possible to reduce the total weight of the door to a not insignificant extent.

20 De ved savsporene 21 dannede dele af lamel lerne 13 og 14 har fortrinsvis ens størrelse, og som tommelfingerregel gælder, at længden mellem et par savsnit bør være mindre end den dobbelte lamelhøjde (dvs. højden målt vinkelret på dørens plan, 25 idet lamellernes højderetning er vinkelret på dækpladerne) .The portions 13 and 14 of the slats formed by the saw grooves 21 are preferably of equal size and, as a rule of thumb, the length between a pair of saw cuts should be less than the double slat height (i.e., the height measured perpendicular to the plane of the door, 25, the height direction of the slats is perpendicular to the cover plates).

I den færdige dør er lamellerne 13, 14 fortrinsvis orienteret i dørens højderetning, men en orientering i bredderetningen er principielt ikke 30 udelukket.In the finished door, the slats 13, 14 are preferably oriented in the height direction of the door, but an orientation in the width direction is in principle not excluded.

Fyldingskonstruktionen 10 er bestemt til at indsættes i en dørramme 18, der ses i lodret snit i fig. 2, og som foroven og forneden har forstærkninger 19, 20. Døren har på kendt måde et spor 22 til op 5The filling structure 10 is intended to be inserted into a door frame 18, seen in vertical section in FIG. 2, and as above and below have reinforcements 19, 20. The door has in a known manner a groove 22 to up 5

tagelse af en tætningsliste 23, der sammen med yderligere tætningslister 24 og 25 giver fornøden tæthed mod en dørkarm 26 og et dørtrin 27 .taking a sealing strip 23 which together with additional sealing strips 24 and 25 provide the necessary tightness against a door frame 26 and a door step 27.

Fig. 3 viser, hvorledes en sektion til en 5 dørfylding 10 kan fremstilles ved, at der mellem et par trælister 28 anbringes tætliggende lameller 13, 14, som fæstnes til et bærende underlag 29, hvorefter det således opnåede aggregat gennemsa-ves med en lamelsav til dannelse af delespor 21.FIG. 3 shows how a section for a door filling 10 can be made by placing adjacent slats 13, 14 which are attached to a supporting support 29 between a pair of wooden moldings 28, after which the assembly thus obtained is pierced with a slab saw to form of part tracks 21.

10 Derpå dækkes aggregatet med en yderligere plade 30 til dannelse af en færdig dørfylding, som med eller uden midterplade 15 kan indsættes i en dørramme 26, fig. 4. I dette tilfælde danner pladerne 29 og 30 de indre plader svarende til pladerne 16, 17 15 i dæklagsarrangementet ifølge fig. 1.10 The assembly is then covered with a further plate 30 to form a finished door filling which can be inserted with or without the middle plate 15 into a door frame 26, fig. 4. In this case, the plates 29 and 30 form the inner plates corresponding to the plates 16, 17 15 of the cover layer arrangement according to FIG. First

Med stiplet streg 31 i fig. 4 er det vist, hvorledes det eksisterende tætningslistespor 22 kan forlænges, så at det går helt gennem rammen.With dashed line 31 in FIG. 4, it is shown how the existing sealing strip groove 22 can be extended so that it goes all the way through the frame.

Ved en sådan operation er det altså muligt at dele 20 en ordinær dør af "dobbeltkonstruktionstype" og med en lamelsav eller et lignende redskab at overskære lamellerne 13, 14 i ønskede længder, hvorefter dørhalvdelene kan sammenføjes, eksempelvis som anvist i svensk fremlæggelsesskrift 349 093.Thus, in such an operation, it is possible to divide an ordinary "double-construction type" door and to cut the slats 13, 14 to desired lengths with a blade saw or similar tool, after which the door halves may be joined together, for example as disclosed in Swedish Patent Specification 349 093.
