Description
Anordning og fremgangsmåte ved fremstilling av byggeelementer av betong. Device and method for the production of concrete building elements.
Det er kjent å fremstille bjelkelag i bygninger i form av inntil hverandre lagte lette byggeelementer av betong, hvert bestående av en avlang betongkassett, lukket med en betongplate og en lydisolering anbragt i et mellomrom mellom denne og kassetten. For å oppnå samme tykkelse for slike sammensatte byggeelementer er det blitt foreslått å legge betongkassetteri på et underlag og å lofte det plateformede element til beregnet hoyde ovenfor kassetten samt i kantmellomrommet mellom disse to elementer å innsproyte skumplast, som tillates å storkne og samtidig innbyrdes forene kassetten og platen. Ifolge denne fremgangsmåte fås sammensatte byggeelementer med noyaktig innbyrdes tykkelse, selv om delelementene ved stopningen har fått innbyrdes vari-erende tykkelse. En ulempe med denne fremgangsmåte er imidlertid dels at lydisoleringen på grunn av stopemassens relative hårdhet ikke blir så god som det er onskelig, og dels at ikke noen ven-tilasjon mellom nærliggende byggeelement blir mulig. It is known to produce joists in buildings in the form of lightweight concrete building elements laid next to each other, each consisting of an oblong concrete cassette, closed with a concrete slab and a sound insulation placed in a space between this and the cassette. In order to achieve the same thickness for such composite building elements, it has been proposed to lay concrete cassettery on a base and to loft the plate-shaped element to a calculated height above the cassette, as well as to inject foam plastic into the edge space between these two elements, which is allowed to solidify and at the same time mutually unites the cassette and the disc. According to this method, composite building elements are obtained with a precise mutual thickness, even if the sub-elements have mutually varying thicknesses during the stuffing. A disadvantage of this method, however, is partly that, due to the relative hardness of the stop compound, the sound insulation is not as good as is desirable, and partly that no ventilation between nearby building elements is possible.
Formålet med den foreliggende oppfinnelse er å avhjelpe nevnte mangler. Ifolge oppfinnelsen er det i mellomrommet mellom platen og den kassett som tjener som bærende element, innlagt parvis samvirkende, av elastisk materiale utforte bærekiler, slik at kilenes hellende flater blir vendt mot hverandre og den totale tykkelse av kilene kan endres ved deres innbyrdes aksiale forskyvning. Ifolge en hensiktsmessig utforelsesform av oppfinnelsen velges materialet til kilene og disses dimensjoner slik at de ved en lastokning på platen med 50 kg sammenpresses 0,2 - 0,5 mm. The purpose of the present invention is to remedy said deficiencies. According to the invention, in the space between the plate and the cassette which serves as a supporting element, supporting wedges made of elastic material are inserted in pairs, cooperating, so that the inclined surfaces of the wedges are turned towards each other and the total thickness of the wedges can be changed by their mutual axial displacement. According to an appropriate embodiment of the invention, the material for the wedges and their dimensions are selected so that when a load is increased on the plate with 50 kg, they are compressed by 0.2 - 0.5 mm.
Hvis det for kilene velges neopren eller lignende isotropt elastisk plastmateriale, elimineres ved stor belastning på platen risiko for koldflytning, som ofte forekommer ved anvendelse av skumplast som lydisolering. If neoprene or a similar isotropic elastic plastic material is chosen for the wedges, the risk of cold liquefaction, which often occurs when foam plastic is used as sound insulation, is eliminated when the plate is heavily loaded.
Oppfinnelsen vedrorer også en fremgangsmåte for fremstilling av byggeelementet ifolge oppfinnelsen, hvilken fremgangsmåte vil bli nærmere forklart i det efterfolgende. The invention also relates to a method for producing the building element according to the invention, which method will be explained in more detail below.
For at oppfinnelsen skal forstås bedre vises det til tegningene, hvor: Fig. 1 viser et vertikalt snitt gjennom skjoten mellom to nærliggende byggeelementer ifolge oppfinnelsen. Fig. 2 er et vertikalt snitt efter linjen II-II i fig. 1 og viser et byggeelement under sammensetning av dettes forskjellige deler, og Fig. 3 er et lignende snitt med platen senket ned til riktig stilling på sine bærekiler. In order for the invention to be better understood, reference is made to the drawings, where: Fig. 1 shows a vertical section through the joint between two adjacent building elements according to the invention. Fig. 2 is a vertical section along the line II-II in fig. 1 and shows a building element under assembly of its various parts, and Fig. 3 is a similar section with the plate lowered to the correct position on its support wedges.
Fig. h viser i perspektiv to samvirkende kiler, og Fig. h shows in perspective two interacting wedges, and
Fig. 5 er et lignende riss i perspektiv av kilene men ifolge en variant av oppfinnelsen. Fig. 5 is a similar view in perspective of the wedges but according to a variant of the invention.
Det på tegningene viste byggeelement består av en med armerings-jern (ikke vist) forsynt betongkassett 1 og en plan betongplate 2 som dekker over denne og som likeledes er forsynt med armer-ingsjern (ikke vist). I mellomrommet 3 mellom disse to delele-menter 1, 2 er det innlagt en lydisolering h som skal beskrives nærmere nedenfor. I hulrommet 5 inne i kassetten 1 er det innlagt et sjikt 6 av mineralull eller lignende varme- og lydiso-lerende materiale. Kassetten 1 understøttes med sine ender av bærebjelker 7• De sammensatte byggeelementer 1, 2 legges opp tett inntil hverandre og overdekkes, efterat fugen 8 mellom nærliggende byggeelement er fylt med fin mortel 9, ved hjelp av et gulvbelegg 10, f.eks. en korkmatte. The building element shown in the drawings consists of a concrete cassette 1 provided with rebar (not shown) and a flat concrete slab 2 which covers this and which is also provided with rebar (not shown). In the space 3 between these two sub-elements 1, 2, a sound insulation h is inserted, which will be described in more detail below. In the cavity 5 inside the cassette 1, a layer 6 of mineral wool or similar heat- and sound-insulating material is laid. The cassette 1 is supported at its ends by support beams 7• The assembled building elements 1, 2 are laid up close to each other and covered, after the joint 8 between adjacent building elements is filled with fine mortar 9, using a floor covering 10, e.g. a cork mat.
Det er innlysende at hvis ovenfor nevnte sammensatte byggeelementer 1, 2 har forskjellig tykkelse, vil det dannes avsatser ved skjoten mellom nærliggende byggeelementer. Korkmatten 10 ville da her efter relativt kort tids anvendelse skades og revne. Med lydisoleringen h ifolge oppfinnelsen vil imidlertid byggeelementene få samme tykkelse, og fremstillingen kan skje i fa-brikk, uten at det blir aktuelt med noen efterjustering på byggeplassen, eftersom det ikke oppstår noen nivåforskjeller. It is obvious that if the above-mentioned composite building elements 1, 2 have different thicknesses, ledges will be formed at the joint between neighboring building elements. The cork mat 10 would then be damaged and crack after a relatively short period of use. With the sound insulation h according to the invention, however, the building elements will have the same thickness, and the production can take place in the factory, without any subsequent adjustment on the construction site being relevant, since no level differences arise.
For å tilveiebringe noyaktig tykkelse på de sammensatte byggeelementer 1, 2 inngår det i anlegget et underlag 11, på hvilket betongkassetten 1 legges slik at den hviler med endene 12 på underlaget. Ovenfor underlaget 11 er innstillbare og fastklem-bare stoppeorgan 13 anbragt loddrett. I anlegget inngår dessuten et antall sugekopper 1<*>+ eller andre hensiktsmessige organer for lofting av betongplaten 2. In order to provide the exact thickness of the composite building elements 1, 2, the plant includes a substrate 11, on which the concrete cassette 1 is placed so that it rests with the ends 12 on the substrate. Above the base 11, adjustable and clampable stop means 13 are arranged vertically. The system also includes a number of suction cups 1<*>+ or other suitable bodies for lofting the concrete slab 2.
Som lydisolering anvendes ifolge oppfinnelsen parvis sammenlagte og på kassettens 1 kant 15 i mellomrommet 3 punktvis utlagte kiler 16 og 17 av neopren eller lignende isotropt elastisk materiale. Kilene 16, 17 er formet således at sideflatene blir stort sett parallelltrapesformet med en hellende flate 18 resp. 19, hvilke flater ved sammenlegning av kilene blir vendt mot hverandre, idet hellingen er slik at den mot kassettkanten 15 vendte plane side 20 av kilen 16 blir parallell med den plane side 21 som vender mot platen 2. Den ene kile 16 er langsmed den hellende flate 18 forsynt med en f jaer 22, og kilen 17 er langsmed den hellende flate 19 forsynt med en tilsvarende langs-gående not 23, i hvilken fjæren 22 passer. According to the invention, wedges 16 and 17 of neoprene or a similar isotropic elastic material are used as sound insulation, joined in pairs and on the edge 15 of the cassette 1 in the space 3. The wedges 16, 17 are shaped so that the side surfaces are largely parallel trapezoidal with a sloping surface 18 or 19, which surfaces when joining the wedges are turned towards each other, the slope being such that the flat side 20 of the wedge 16 facing the cassette edge 15 is parallel to the flat side 21 facing the plate 2. One wedge 16 is along the inclined surface 18 is provided with a spring 22, and the wedge 17 is provided along the inclined surface 19 with a corresponding longitudinal groove 23, in which the spring 22 fits.
Ifolge den i fig. 5 viste utforelse er de hellende flater 18' og 19'• på kilene 16' og 17' forsynt med tversgående rifler 2k, som ved sammenlegning av kilene griper inn i hverandre. According to the one in fig. 5, the inclined surfaces 18' and 19'• on the wedges 16' and 17' are provided with transverse ribs 2k, which engage each other when the wedges are brought together.
Kilene i den i fig. h viste utforelse kan også være utfort med tilsvarende tversgående rifler. På grunn av not- og fjærfor-bindelsen 22, 23 og riflene 2h bibeholdes kilene 16, 17 i inn-stilt stilling. The wedges in the one in fig. The embodiment shown in h can also be fitted with corresponding transverse rifles. Because of the tongue and groove connection 22, 23 and the rifles 2h, the wedges 16, 17 are maintained in the set position.
Ved sammensetning av byggeelementene 1, 2 anbringes kassetten 1 på underlaget 11 (fig. 2), og en betongplate 2 legges lost på kassetten, hvorpå sugekoppene lh fores ned til anlegg mot platens 2 overside. Et visst undertrykk anvendes inne i sugekoppene, hvorpå disse loftes og tar med seg platen 2, inntil denne slår an mot stoppeorganene 13. Hvis tykkelsen A av det sammensatte byggeelement 1, 2 skal være f.eks. 300 mm, innstilles stoppe-anslaget 13 på en hoyde B ovenfor underlaget 11, som med en viss verdi, f.eks. 30 mm, er storre enn tykkelsen A av det ferdige byggeelement. Hoyden B blir således 330 mm. Hoyden C på mellomrommet 3 mellom kassetten 1 og platen 2 måles. Hvis hoyden C fastslås til f.eks. h2 mm, innstilles tykkelsen D på de sammenlagte kiler 16, 17 til h2 - 30 = 12 mm. Denne tykkelse D innstilles ved aksial innbyrdes forskyvning av kilene 16, 17. Når derefter parene av kiler 16, 17 legges ut punktvis på kassettkanten 15 og platen 2 senkes ned på kilene (fig. 3)5 fås den riktige tykkelse A av det sammensatte byggeelement. When assembling the building elements 1, 2, the cassette 1 is placed on the base 11 (fig. 2), and a concrete slab 2 is placed loosely on the cassette, after which the suction cups lh are brought down to abut against the upper side of the slab 2. A certain negative pressure is applied inside the suction cups, whereupon these lift up and take the plate 2 with it, until it hits the stop members 13. If the thickness A of the composite building element 1, 2 is to be e.g. 300 mm, the stop stop 13 is set at a height B above the substrate 11, which with a certain value, e.g. 30 mm, is greater than the thickness A of the finished building element. Height B will thus be 330 mm. The height C of the space 3 between the cassette 1 and the plate 2 is measured. If the height C is determined to e.g. h2 mm, the thickness D of the combined wedges 16, 17 is set to h2 - 30 = 12 mm. This thickness D is set by axial mutual displacement of the wedges 16, 17. When the pairs of wedges 16, 17 are then laid out point by point on the cassette edge 15 and the plate 2 is lowered onto the wedges (fig. 3)5, the correct thickness A of the assembled building element is obtained .
En annen måte å sammensette byggeelementer på er på ovenfor angitte måte å lofte platen 2 til riktig hoyde A og derefter fore inn de med bindemiddel forsynte kiler 16, 17 i mellomrommet 3 samt derefter med et saksformet verktoy forskyve kilene i hvert par mot hverandre slik at de fastklemmes mot hverandre og den nedre kile 16 mot det kassettformede elements 1 ovre kant og den ovre kile 17 mot platens 2 underside. Another way of assembling building elements is, in the manner indicated above, to raise the plate 2 to the correct height A and then insert the wedges 16, 17 provided with binder into the space 3 and then with a scissor-shaped tool, move the wedges in each pair towards each other so that they are clamped against each other and the lower wedge 16 against the upper edge of the cassette-shaped element 1 and the upper wedge 17 against the underside of the plate 2.
Antall kilepar og delingen mellom dem samt valget av materiale og dimensjon for kilene bor være slik at ved en lastokning på 50 kg på platen 2, fås en sammenpresning av samtlige kilepar med ca. 0,2 - 0,5 mm. The number of pairs of wedges and the division between them as well as the choice of material and dimension for the wedges should be such that, with a load increase of 50 kg on plate 2, a compression of all pairs of wedges with approx. 0.2 - 0.5 mm.
Som det fremgår av fig. 1 og 2 blir det mulig å lede en luft-strom, f.eks. en varmluftstrom, gjennom mellomrommet 3 mellom kassetten 1 og platen 2 i samtlige av bjelkelagets sammensatte byggeelementer. As can be seen from fig. 1 and 2, it becomes possible to direct an air current, e.g. a hot air stream, through the space 3 between the cassette 1 and the plate 2 in all of the beam layer's composite building elements.
For innbyrdes aksial forskyvning av kilene 16, 17 anvendes fortrinnsvis et saksformet verktoy, som er således innrettet at når verktoyets to grener fores inn i mellomrommet 3 mellom kassetten 1 og platen 2, slik at disse grener ligger an den ene mot kassettkanten 15 og den andre mot platen 2, forskyver verktoyets to motsatte grener de to kiler 16, 17 aksielt mot eller fra hverandre til riktig sammensatt tykkelse D, hvorefter kilene med denne totale tykkelse innfores i mellomrommet 3 og anbringes med jevne mellomrom på kassettkanten 15. For mutual axial displacement of the wedges 16, 17, a scissor-shaped tool is preferably used, which is arranged in such a way that when the two branches of the tool are inserted into the space 3 between the cassette 1 and the plate 2, so that these branches lie against the cassette edge 15 and the other against the plate 2, the two opposite branches of the tool displace the two wedges 16, 17 axially towards or apart to the correct composite thickness D, after which the wedges with this total thickness are inserted into the space 3 and placed at regular intervals on the cassette edge 15.
Den viste og beskrevne utforelsesform må bare betraktes som et eksempel, og byggeelementets forskjellige deler kan konstruktivt forandres på flere måter innenfor rammen av kravene. Det bærende element 1 kan gis annen form enn kassettform. The shown and described embodiment must only be considered as an example, and the various parts of the building element can be constructively changed in several ways within the scope of the requirements. The supporting element 1 can be given a different shape than cassette shape.
Kilene 16, 17 bor for innforing i mellomrommet 3 være forsynt med hurtig storknende bindemiddel såvel på de hellende flater 18, 19 som på de innbyrdes parallelle flater 20, 21, slik at kileparene ved nedsenkning av platen 2 blir fast forenet med såvel denne som kassetten 1. v For insertion into the space 3, the wedges 16, 17 must be provided with a fast-setting binder both on the inclined surfaces 18, 19 and on the mutually parallel surfaces 20, 21, so that the pairs of wedges when the plate 2 is lowered are firmly united with both this and the cassette 1st v
