Abstract

This invention concerns a pre-fabricated supporting outer wall element (1) primarily designed for cold outer walls, apartment outer walls or curtain wall elements. The element (1) is constructed in its supporting part of wood or a steel framework (20) having pairs of beams (2) fixed vertically (A) at a distance in relation to one another with force-extracting stiffening uprights (2) extending between the beams and fully covering insulation (4, 6) on beams (2) and uprights (3). On the external surface of the element (1), a layer of reinforced concrete (5) is applied joined together with the framework (20) using nails (21) or other attachment material.<IMAGE>

Description

513 679 Det sagda isoleringsskiktet bildar även stöd vid gjutförfarandet och riskerar ej att trasas sönder på grund av tung betongmassa, sásom kan vara fallet med spännpapp vid det kända, speciellt om det är tomt under pappen. The said insulating layer also forms a support during the casting process and does not risk being torn due to heavy concrete mass, as may be the case with clamping cardboard at the known point, especially if it is empty under the cardboard.

Uppfinningen beskrives nedan såsom ett par föredragna utföringsexempel med hänvisning till bifogade ritningar, på vilka Fig 1-4 visar ett första utföringsexempel med olika snittvyer av en vägg, och Fig 5 visar ett andra utföringsexempel av en vägg med inàtvänd betongyta.The invention is described below as a pair of preferred embodiments with reference to the accompanying drawings, in which Figs. 1-4 show a first embodiment with different sectional views of a wall, and Fig. 5 shows a second embodiment of a wall with an inverted concrete surface.

Den föreliggande uppfinningen avser ett prefab- ricerat bärande ytterväggselement l; 11, för källarelement, vàningselement eller utfackningselement, och som innefattar en betongskiva 5 resp 12 samt invändigt i elementet 1; 11 mottagen termisk isolering 4, 6 av önskat slag.The present invention relates to a prefabricated load-bearing outer wall element 1; 11, for basement elements, floor elements or unfolding elements, and which comprises a concrete slab 5 and 12, respectively, and inside the element 1; 11 received thermal insulation 4, 6 of the desired type.

Elementet 1; 11 är i sin inre bärande del utfört med ett trä och/eller stålregelverk 20 som är bildat av parvisa reglar 2 som sträcker sig horisontellt när elementet 1; ll är anordnat uppställt i dess normala byggnadsposition, d.v.s. upprättstående i huvudsak vertikalt. _ Sagda horisontella balkformade regler 2 är belägna på inbördes avstånd A fràn varandra med mellan balkarna 2 sig sträckande desamma förbindande vertikala kraftupptagande förstyvningsstàndare 3.Element 1; 11 is in its inner supporting part made of a wood and / or steel frame 20 which is formed by pair of bars 2 which extend horizontally when the element 1; ll is arranged arranged in its normal building position, i.e. upright mainly vertically. Said horizontal beam-shaped rules 2 are located at a mutual distance A from each other with the same connecting vertical force-absorbing stiffening posts 3 extending between the beams 2.

Mellan balkarna 2 och ståndarna 3 är en hel- täckande termisk isolering 6 mottagen och som kan bildas av t.ex. mineralull eller av cellplast i form av t.ex. ilagda skivor av isolermaterialet ifråga. Ett motgjutet termiskt isoleringsmaterialskikt 4 är beläget mellan den gjutna betong- skivan 5 resp 12 och det sagda regelverket 20.Between the beams 2 and the uprights 3 a comprehensive thermal insulation 6 is received and which can be formed by e.g. mineral wool or of cellular plastic in the form of e.g. inserted sheets of the insulating material in question. A counter-cast thermal insulation material layer 4 is located between the cast concrete slab 5 and 12, respectively, and the said structure 20.

Den sagda betongskivan 5 resp 12 kan vara belä- gen antingen pà elementets 1 utátvända sida, beroende på om elementet 1 skall nyttjas som ett väggelement med utvändigt betongytskikt, se Fig l-4, eller pà elementets ll inåtvända 513 679 sida, se Fig 5, beroende på om elementet 11 skall fungera med färdigt inre betongytskikt.The said concrete slab 5 and 12, respectively, can be located either on the outwardly facing side of the element 1, depending on whether the element 1 is to be used as a wall element with an external concrete surface layer, see Figs. 1-4, or on the inwardly facing side of the element 11, see Fig. 5 , depending on whether the element 11 is to function with a finished inner concrete surface layer.

Den sagda betongskivan 5 resp 12, som kan inne- hålla armering 10 av känt slag, kan ha en tjocklek på mellan cza 40 och 60 mm, men avpassas efter behov, t.ex. om elementet 1, ll, skall nyttjas som källarvägg.The said concrete slab 5 and 12, respectively, which may contain reinforcement 10 of known type, may have a thickness of between about 40 and 60 mm, but be adapted as required, e.g. if the element 1, ll, is to be used as a basement wall.

För effektiv fasthållning är den sagda betong- skivan 5 resp 12 säkert sammankopplad med regelverket 20 och vilket kan åstadkommas i samband med gjutförfarandet av betong- skivan mot isoleringen 2. Sagda sammankoppling àstadkommes medelst fästorgan 21 i form av spik, skruv eller liknande.For effective holding, the said concrete slab 5 and 12, respectively, is securely connected to the regulations 20 and which can be achieved in connection with the casting process of the concrete slab against the insulation 2. Said coupling is achieved by means of fastening means 21 in the form of nails, screws or the like.

Byggelementen 1; 11, kan levereras med: I. helt eller delvis öppen insida, II. med invändig skiva 8 som täcker för elementets insida fabriksmonterad, eller III. med lös skiva 8, t.ex. gips- eller fiberskiva som monteras på plats efter uppställning och sammanbindning sidledes av elementen l med spik 7, skruv- eller annat infäst- ningsmedel.Building elements 1; 11, can be delivered with: I. fully or partially open inside, II. with internal plate 8 covering the inside of the element factory-fitted, or III. with loose disc 8, e.g. gypsum or fibreboard which is mounted on site after installation and bonding laterally of the elements 1 with nails 7, screw or other fastening means.

I Fig l-4 visas element 1 uppresta och samman- bundna med varandra enligt ovan angivet där betongskivan 5 är utåtvänd och att betongskivorna 5-5 fogas samman med varandra medelst lämplig fogmassa 9 av känt slag och som tätar i skarven 22 mellan elementen 1-1 utifrån.In Figs. 1-4, elements 1 are shown erected and connected to each other as indicated above, where the concrete slab 5 is facing outwards and that the concrete slabs 5-5 are joined together by means of a suitable joint compound 9 of known type and which seals in the joint 22 between the elements 1- 1 from the outside.

I Fig 4 visas även hur en förstärkningsskiva 25, exempelvis en gips- eller spånskiva är anordnad mellan regelverket 20 för att underlätta vid gjutningen på isoleringen 4 så att inte denna bågnar ner i regelverket 20.Fig. 4 also shows how a reinforcing board 25, for example a plasterboard or chipboard, is arranged between the regulations 20 in order to facilitate the casting of the insulation 4 so that it does not bend down into the regulations 20.

I Fig 5 visas en variant av ett element 11, där betongskivan 12 är vänd inàšot byggnadens inre utrymme 23 och där utsidan av elementet ll täckes av en ytterbeklädnad 13 i form av trä-, plåt- eller annat ytterbeklädningsmaterial.Fig. 5 shows a variant of an element 11, where the concrete slab 12 faces the inner space 23 of the building and where the outside of the element 11 is covered by an outer cladding 13 in the form of wood, sheet metal or other outer cladding material.

Elementet 1; ll, i fråga lämpar sig att hante- ras utan stora dyra kranar och andra lyftmaskiner och är även lätta att arbeta med. Dock är uppfinningen ej begränsad till 513 679 ovan beskrivna och på ritningar visade utföranden utan kan varieras inom ramen för patentkraven utan att uppfinningstanken fràngås.Element 1; ll, in question is suitable to be handled without large expensive cranes and other lifting machines and is also easy to work with. However, the invention is not limited to 513,679 described above and shown in drawings, but can be varied within the scope of the claims without departing from the spirit of the invention.
