Description

Monikerroksinen saneerausrakennuselementtiMulti-storey renovation building element

Keksinnön kohteena on monikerroksinen saneerausrakennuselementti, jossa on lämmöneristysmateriaalia oleva sydänosa ja sitä molemmin puolin peittävät pintale-vyt, joissa pintalevyissä on yhdessä pituussuuntaisessa reunassa urospontti ja vastakkaisessa reunassa naaraspontti.The present invention relates to a multilayer renovation building element having a core part of a heat-insulating material and surface plates covering both sides, the surface plates having a groove on one longitudinal edge and a groove on the opposite edge.

Suomessa, kuten monissa muissakin maissa, on paljon korjaustarpeessa olevia rakennuksia. Niiden korjaamiseksi on kehitetty erilaisia saneerauselementtejä, jotka ripustetaan esim. kiinnikkeiden avulla kantaviin rakenteisiin. Nämä tunnetut ratkaisut ovat kuitenkin yleensä kompromisseja lämmöneristyksen ja toisaalta riittävän tuuletuksen välillä kosteusongelmien välttämiseksi.In Finland, as in many other countries, there are many buildings in need of repair. To remedy them, various renovation elements have been developed, which are suspended, for example, by means of brackets on load-bearing structures. However, these known solutions are generally trade-offs between heat insulation and adequate ventilation to avoid moisture problems.

Julkaisussa WO9522670 on kuvattu elementti, jossa on metallinen ulkopinta ja siihen kiinnitetty lämmöneriste, joka on sovitettu asettumaan suoraan vasten päällystettävää alusrakennetta. Tämä vaatii erillisen kiinnityslistan käytön, joka metallisesta ulkopinnasta alusrakenteeseen. Myös julkaisusta CH525359 tunnetaan päällys-tyselementti, jossa on metallinen ulkopinta ja siihen liitetty lämmöneristyskerros. Julkaisussa GB1468534 on kuvattu kylmähuoneiden eristysratkaisu, jossa on lämmöneristyskerros ja sen molemmin puolin olevat pintalevyt. Julkaisussa GB2306984 on kuvattu rakennuselementti, jossa on vaneria tai vastaavaa oleva pintalevy ja siihen liitetyt koolingit. Pintalevy on rei'itetty. Eristemateriaali lisätään työmaalla pinta-levyn ja vastakkaisen työmaalla kiinnitettävän pintalevyn, joka on esim. kipsilevyä, väliin. JP2004092312 esittää polystyreeniä tai vastaavaa olevan eristyslevyn, jossa on yhdessä pinnassa tuuletusuria ja niitä peittävä kangas, jonka päälle on järjestetty laastikerros. CA2614522 esittää polystyreeniä olevan elementin, jonka pintaan on järjestetty sementtipitoinen pinnoite. Alusrakennetta vasten tuleva pinta on varustettu tuuletusurituksella.WO9522670 discloses an element having a metallic outer surface and a heat insulator attached thereto, which is adapted to rest directly against the substrate to be coated. This requires the use of a separate fastening strip, from the metal outer surface to the substructure. Also known from CH525359 is a coating element having a metallic outer surface and a heat insulating layer attached thereto. GB1468534 describes a cold room insulation solution having a heat insulating layer and surface panels on both sides thereof. GB2306984 discloses a building element having a surface panel of plywood or the like and curbs attached thereto. The face plate is perforated. The insulation material is inserted between the surface plate at the construction site and the opposite surface plate that is to be fixed at the construction site, such as gypsum board. JP2004092312 discloses an insulating sheet of polystyrene or the like, which has, on one surface, ventilation grooves and a cloth covering them with a layer of mortar on it. CA2614522 discloses a polystyrene element having a cementitious coating on its surface. The surface facing the substructure is equipped with a vent.

Esillä olevan keksinnön päämääränä on aikaansaada luotettava saneerauselementti vanhojen rakennuksien, erityisesti toimitilarakennuksien julkisivujen saneeraamiseksi, joka elementti mahdollistaa hyvän lämmöneristyksen ja tiiveyden sekä samalla hyvän tuuletuksen aikaansaamisen.The object of the present invention is to provide a reliable renovation element for the renovation of the facades of old buildings, in particular office buildings, which enables good thermal insulation and airtightness, while also providing good ventilation.

Tämän päämäärän saavuttamiseksi keksinnön mukaiselle saneerausrakennusele-mentille on tunnusomaista se, että saneerausrakennuselementin sisempään pintale-vyyn on muodostettu ainakin yksi aukko, joka on peitetty vesihöyryä läpäisevällä kalvomateriaalilla, ja että saneerausrakennuselementin sydänosan eristemateriaaliin on muodostettu ainakin yksi tuuletuskanava, joka avautuu suoraan tai erillisen yh-dyskanavan kautta ulkoilmaan.To achieve this object, the renovation building element according to the invention is characterized in that at least one opening is formed in the inner surface plate of the renovation building element, covered with a water vapor-permeable membrane material, and through the open air.

Keksinnön mukainen ratkaisu mahdollistaa rakennuksessa olevan kosteuden poistumisen vesihöyryä läpäisevän kalvon läpi ja edelleen eristemateriaalin läpi tuuletus-kanavaan, joka johtaa kosteuden joko suoraan tai yhdyskanavan kautta ulkoilmaan kuivattaen rakennusta. Erittäin märkiä rakenteita saneerattaessa saneerausrakennuselementin ja vanhan rakenteen väliin voidaan järjestää tilapäinen tuuletusrako, joka on suljettavissa rakenteen kuivuttua riittävästi, jotta lämmöneristyskyky saadaan pidettyä mahdollisimman hyvänä.The solution according to the invention allows the moisture in the building to escape through the water vapor permeable membrane and further through the dielectric material to the ventilation duct, which conducts moisture either directly or through a duct to the open air, drying the building. During the renovation of very wet structures, a temporary ventilation gap can be provided between the renovation building element and the old structure, which can be closed after the structure dries sufficiently to maintain the best thermal insulation performance.

Seuraavassa keksintöä selostetaan oheisiin piirustuksiin viitaten, joissa: kuvio 1 esittää kaaviollisena periaatekuvana saneerausrakennuselementtien sijoittelua pystyasennuksessa, kuvio 2 esittää kaaviollisena periaatekuvana saneerausrakennuselementtien sijoittelua vaaka-asennuksessa, ja kuvio 3 esittää kuvion 1 mukaisen vaaka-asennuksen osittaista leikkausta isometrisenä kuvana nuolien III-ΠΙ osoittamassa suunnassa.In the following, the invention will be described with reference to the accompanying drawings, in which: Figure 1 is a schematic schematic view of the arrangement of renovation building elements in a vertical installation;

Kuviossa 1 on esitetty saneerausrakennuselementtien 2 sijoittelua pystyasennuksessa. Saneerausrakennuselementtien 2 korkeus h on tyypillisesti 3-12 m ja leveys 1,2 m. Tuuletuskanava on järjestetty edullisesti elementtien väliseen saumakohtaan 10, joka kanava avautuu yläpäästään ulkoilmaan suojattuna sateelta esim. suojapellin (ei esitetty) avulla. Kun elementit on asennettu pystyyn voi pystysuunnassa olla yksi tai useampi elementti asennettuna päällekkäin. Jos esim. rakennus on 20 m korkea, voi siinä olla 2 kappaletta 10 metriä korkeita elementtejä. Tällöin tuuletus tapahtuu jokaisen elementin ylä-ja alareunasta eli myös elementtien välisessä saumassa tapahtuu tuuletusta.Figure 1 shows the arrangement of the renovation building elements 2 in a vertical installation. Renovation building elements 2 typically have a height h of 3 to 12 m and a width of 1.2 m. The ventilation duct is preferably arranged at the seam 10 between the elements, which opens at its upper end into the open air, protected by rain e.g. by a shroud (not shown). When the elements are mounted vertically, one or more elements may be vertically mounted on top of each other. For example, if a building is 20 m high, it can have 2 elements 10 m high. In this case, the ventilation takes place at the top and bottom of each element, i.e. the seam between the elements is also ventilated.

Kuviossa 2 on esitetty saneerausrakennuselementtien 2 sijoittelua vaaka-asennuksessa. Saneerausrakennuselementtien 2 pituus L on tyypillisesti 3-12 m ja leveys W 1,2 m. Tuuletuskanava on edullisesti järjestetty elementtien väliseen vaakasuuntaiseen saumakohtaan 11, joka kanava avautuu elementtien välisen pystysauman 12 yhteyteen järjestettyyn yhdyskanavaan, joka avautuu yläpäästään ulkoilmaan suojattuna sateelta esim. suojapellin avulla.Figure 2 shows the layout of the renovation building elements 2 in horizontal installation. The length of the renovation building elements 2 is typically 3 to 12 m and the width W is 1.2 m. The ventilation duct is preferably arranged at a horizontal seam 11 between the elements, which opens into a connecting duct arranged at the upper end of the element seam 12.

Kuviossa 3 on esitetty eräs saneerausrakennuselementin 2 suoritusmuotoesimerkki vaaka-asennuksessa. Saneerausrakennuselementti 2 käsittää edullisesti mineraali-villaa olevan sydänosan 2c, jonka molemmille pääpinnoille on kiinnitetty, edullisesti liimaamalla, pintalevyt 2a, 2b, jotka ovat edullisesti muovipinnoitettua teräsohutle-vyä. Mineraalivillakerros muodostuu edullisesti rakennevillalamelleista, joissa kuidut ovat olennaisesti kohtisuorassa pintalevyihin 2a, 2b nähden. Pintalevyjen vaakasuuntaiseen alareunaan on tehty naaraspontti 4 ja yläreunaan urospontti 5. Esitetyssä suoritusmuodossa sisempään pintalevyyn on tehty aukko 7, joka on peitetty sisemmän pintalevyn ulkopintaan kiinnitetyllä vesihöyryä läpäisevällä kalvolla 6. Kalvona voi olla esim. TYVEK ® -kalvo, joka on kiinnitetty edullisesti liimaamalla sisemmän pintalevyn ulkopintaan. Kalvon kiinnitys voidaan tehdä myös mekaanisesti. Aukkoja 7 voi olla useita ja ne voivat olla keskenään erimuotoisia ja pinta-alaltaan erikokoisia. Aukkojen kokonaispinta-ala on edullisesti n. 10 % sisemmän pintalevyn pinta-alasta, minimin ollessa n. 5 %. Aukkojen kokonaispinta-ala voi olla tilanteesta riippuen isompikin, esim. 15 %:sta jopa 80 %:iin, mikäli sisemmän pintalevyn lujuus sen sallii. Liimattaessa sydänosaa 2c autolliseen pintalevyyn 2b jää sydänosa ilman liimakerrosta pintalevyssä olevien aukkojen 7 kohdalta, jolloin kosteus pääsee siirtymään aukkojen kohdalla mineraalivillan läpi suhteellisen helposti tuuletuskanavaan 9. Tuuletuskanava 9 on esitetyssä suoritusmuodossa järjestetty lähelle saneerausrakennuselementin 2 ulommaista pintalevyä 2a naaraspontin 4 läheisyyteen. Tuuletuskanavan 9 sijoittaminen avautumaan päällekkäisten saneerausrakennuselementtien väliseen saumakohtaan tekee tuuletuskanavan valmistamisen suhteellisen helpoksi. Se voidaan tehdä esim. jyrsimällä sydänosan reunaan halutun syvyinen ja levyinen ura saneerausrakennuselementin valmistamisen yhteydessä. Tuuletuskanavia 9 voi olla useampi kuin yksi ja se voi sijaita myös muualla kuin esitetyssä kohdassa. Tuuletuskanavan muoto on esitetyssä suoritusmuodossa suorakulmio, mutta sen muoto voi olla muukin, esim. puolipyöreä.Figure 3 shows an exemplary embodiment of the renovation building element 2 in horizontal installation. The renovation building element 2 preferably comprises a core-wool core part 2c, on which both main surfaces are fastened, preferably by gluing, to the surface plates 2a, 2b, which are preferably plastic coated steel sheet. The mineral wool layer preferably consists of structural wool lamellas in which the fibers are substantially perpendicular to the surface plates 2a, 2b. In the illustrated embodiment, the inner surface plate is provided with an opening 7 which is covered with a water vapor-permeable membrane attached to the outer surface of the inner surface plate, e.g. the outer surface. The film may also be mechanically fastened. The openings 7 may be several and may have different shapes and sizes in relation to one another. The apertures preferably have a total surface area of about 10% of the surface area of the inner surface plate, with a minimum of about 5%. Depending on the situation, the total surface area of the openings may be larger, e.g. from 15% up to 80%, if the strength of the inner surface plate allows it. When the core portion 2c is glued to the autosurface panel 2b, the core portion is left without an adhesive layer at the openings 7 in the surface plate, allowing moisture to pass through the openings through the mineral wool relatively easily into the ventilation passage 9. Placing the ventilation duct 9 to open at the seam between the overlapping renovation building elements makes the manufacturing of the ventilation duct relatively easy. This can be done, for example, by milling a groove of the desired depth and width to the edge of the core part during the manufacture of the renovation building element. The venting ducts 9 may be more than one and may also be located elsewhere than at the position shown. In the embodiment shown, the shape of the ventilation duct is a rectangle, but it may also have other forms, e.g. semi-circular.

Saneerausrakennuselementti 2 kiinnitetään edullisesti erillisten kiinnikkeiden (ei esitetty) avulla vanhaan kantavaan seinään 1. Seinän 1 epätasaisuuksien kompensoimiseksi saneerausrakennuselementin 2 ja seinän 1 väliin voidaan sijoittaa pehmeää mineraalivillaa oleva eristekerros 8. Eristekerros voidaan kiinnittää valmiiksi saneerausrakennuselementin sisempään pintalevyyn 2b tai se voidaan asentaa työmaalla seinään 1 ennen saneerausrakennuselementin asentamista paikoilleen. Mikäli saneerattava seinä on erittäin märkää pehmeä villa voidaan jättää ainakin osittain pois siten, että saneerausrakennuselementin 2 ja seinän 1 väliin muodostuu yksi tai useampi väliaikainen pystysuuntainen tuuletuskanava 13, joka/jotka suljetaan ala-ja yläpäästään kosteuspitoisuuden laskettua riittävästi. Tällöin lämmöneristyskyky muodostuu alkukuivatuksen jälkeen hyväksi, kun lämpöä ei pääse karkaamaan rakennuksen seinästä 1 väliaikaisen tuuletuskanavan kautta.Preferably, the renovation building element 2 is fastened to the old load-bearing wall 1 by means of separate fasteners (not shown). installing the renovation building element. If the wall to be renovated is a very wet soft wool, at least in part can be omitted so that one or more temporary vertical ventilation ducts 13 are formed between the renovation building element 2 and the wall 1, which are closed at their lower and upper ends when the moisture content is sufficiently reduced. In this case, after the initial drying, the heat insulating capacity is good when heat cannot escape from the wall 1 of the building through a temporary ventilation duct.
