Betonipilarin valmistusmenetelmä - Framställningsförfarande för en betongpelare 5 Tämän keksinnön kohteena on betonipilarin valmistusmenetelmä, jossa betonia ruiskutetaan määrätyn muotoista betonipilarin runkorakennelmaa vasten ja jota runkorakennelmaa pyöritetään runkorakennelmaan kiinnitetyn pyöritysakselin ympäri samanaikaisesti, kun betonin ruiskutus suoritetaan ja 10 joka ruiskutettu betonipinta muotoillaan ruiskutuksen jälkeen esim. määrätyn muotoisella vanteella.The present invention relates to a method of manufacturing a concrete column, in which concrete is sprayed against a frame structure of a concrete pillar of a certain shape .
Seuraavissa julkaisuissa on esitetty laitteita ja menetelmiä, jotka liittyvät tekniikan tasoon: US-patentti 15 4 426 345, US-patentti 3 327 433, GB-patentti 1 474 717, DE- patentti 673 520, DE-patentti 560 766 ja DE-patentti 435 567. DE-patentissa 435 567, jossa on esitetty eräs tämäntapainen menetelmä, betonia ruiskutetaan määrätyn muotoista muottia vasten, minkä jälkeen ruiskutettu tuore be-20 tonipinta tasoitetaan, tässä tapauksessa pingotetun langan avulla. Tämän jälkeen annetaan betonipilarin kuivua, minkä jälkeen se poistetaan tukialustasta ja pyörimisakselista. Betonipilari on nyt valmis. Mikäli betonipilarin pintaa vielä halutaan käsitellä esim. sileämmäksi, se tehdään käsityö-25 nä käsikäyttöisillä hiomalaitteilla. Tämä on hyvin työlästä ja aikaavievää.The following publications disclose devices and methods related to the prior art: U.S. Patent 15,426,345, U.S. Patent 3,327,433, GB Patent 1,474,717, DE Patent 673,520, DE Patent 560,766, and DE Patent 435 567. In DE patent 435 567, which discloses a method of this kind, concrete is sprayed against a mold of a certain shape, after which the sprayed fresh be-20 ton surface is smoothed, in this case by means of a tensioned wire. The concrete column is then allowed to dry, after which it is removed from the support base and the axis of rotation. The concrete pillar is now ready. If it is desired to treat the surface of the concrete pillar even smoother, for example, it is done by hand with 25 hand-held grinders. This is very laborious and time consuming.
Keksinnön tarkoituksena on poistaa edellä esitetty epäkohta uudenlaisella valmistusmenetelmällä. Keksinnön mukaiselle 30 valmistusmenetelmälle on tunnusomaista se, että betonipilari saa kuivua pyöritysakseliin kiinnitettynä ja kuivumisen jälkeen betonipilarin pinta hiotaan hiomalaitteella ja pyörittämällä betonipilaria pyörimisakselinsa ympäri joko samassa pyörittämislaitteessa kuin betonipilarit on ruiskutettu tai 35 erillisessä hiomalaitteessa. Keksinnön avulla hionta minimoituu ja pilarin keskitys on helppoa, mikäli se siirretään erilliseen hiomalaitteeseen. Saadaan helposti oikein mitoitettu tuote, jonka pintaa ei enää tarvitse jälkikäsitellä.The object of the invention is to eliminate the above drawback by a new type of manufacturing method. The manufacturing method 30 according to the invention is characterized in that the concrete column is allowed to dry attached to the axis of rotation and after drying the surface of the concrete column is ground with a grinder and rotating the concrete column about its axis of rotation either in the same rotating device as sprayed concrete or in a separate grinder. By means of the invention, grinding is minimized and the centering of the column is easy if it is transferred to a separate grinding device. A properly dimensioned product is easily obtained, the surface of which no longer needs to be post-treated.

Keksinnön eräälle sovellutusmuodolle on tunnusomaista se, että betonipilaria pyöritetään yhtäjaksoisesti samanaikaisesti kun sen pintaa hiotaan esim. korkeakierroksisella te-räkiekolla. Teräkiekkoa siirretään näin ollen vain pystysuo-5 rassa olevaa rataa pitkin, jolloin akselinsa ympäri pyörivän betonipilarin pinta tulee hiotuksi.An embodiment of the invention is characterized in that the concrete column is rotated continuously at the same time as its surface is ground, e.g. with a high-speed steel disc. The blade disc is thus moved only along a vertical path, whereby the surface of the concrete column rotating about its axis becomes ground.
Keksinnön eräälle toiselle sovellutusmuodolle on tunnusomaista se, että betonipilaria pyöritetään jaksottain ja 10 betonipilarin pintaa hiotaan yksi pitkä sivu kerrallaan esim. korkeakierroksisella teräkiekolla. Näin ollen voidaan hioa kulmikkaita ja monimuotoisia pilareita.Another embodiment of the invention is characterized in that the concrete column is rotated periodically and the surface of the 10 concrete columns is ground one long side at a time, e.g. with a high-speed blade disc. Thus, angular and versatile pillars can be ground.
Keksinnön eräälle sovellutusmuodolle on vielä tunnusomaista 15 se, että betonipilarin hiomisen jälkeen betonipilari leikataan irti pyörimisakselista. Pitkästä betonipilarista voidaan näin ollen heti leikata halutun pituisia betonipilari-tuotteita, joita ei enää tämän jälkeen tarvitse jälkikäsi-tellä.Another embodiment of the invention is characterized in that after grinding the concrete column, the concrete column is cut off from the axis of rotation. The long concrete column can thus be immediately cut into concrete column products of the desired length, which no longer need to be post-processed.

Keksintöä selostetaan seuraavassa esimerkin avulla viittaamalla oheiseen piirustukseen, joka esittää betonipilarin valmistusmenetelmään käytettävää laitetta.The invention will now be described, by way of example, with reference to the accompanying drawing, which shows an apparatus for use in a method of manufacturing a concrete column.
25 Betonipilarin valmistusmenetelmässä ruiskutetaan betoniruis-kulla 1 betonia määrätyn muotoista betonipilarin runkoraken-nelmaa vasten. Runkorakennelmaa ei ole esitetty kuvissa, mutta se voi olla peltiputki, verkkorakennelma tai jopa molempia. Runkorakennelmaa pyöritetään runkorakennelmaan kiin-30 nitetyn pyöritysakselin 2 ympäri koneiston 3 avulla. Samanaikaisesti kun pyöritys tapahtuu, ruiskutetaan betonia runkorakennelmaa vasten, yleensä alhaalta ylöspäin. Ruiskutettu betonipinta muotoillaan vanteen 4 avulla liikuttamalla sitä betonipilaria pitkin ylös ja takaisin ala-asentoon. Betoni-35 pilari saa nyt kuivua pyöritysakseliin 2 kiinnitettynä, joko tässä ruiskutuslaitteessa tai erillisessä kuivumispaikassa. Kuivumisen jälkeen betonipilarin pinta hiotaan pyörittämällä pilaria akselin 2 ympäri samanaikaisesti kun pintaa hiotaan li 90842 3 hiomalaitteella 5, jossa on korkeakierroksinen teräkiekko 6. Hiominen tapahtuu ylhäältä alaspäin nuolen osoittamalla tavalla. Betonipilari leikataan tämän jälkeen irti pyörimisakselistaan 2. Esimerkissä on esitetty ympyränmuotoinen beto-5 nipilari, mutta se voi yhtä hyvin olla kulmikas tai jopa vielä monimuotoisempi. Pintaan voidaan myös hioa erilaisia kuvioita.25 In the method of manufacturing a concrete column, 1 concrete is sprayed with concrete grout against a frame of a concrete column of a certain shape. The frame structure is not shown in the figures, but it can be a sheet metal pipe, a net structure, or even both. The frame structure is rotated about a axis of rotation 2 fixed to the frame structure by means of a mechanism 3. At the same time as the rotation takes place, the concrete is sprayed against the frame structure, usually from the bottom up. The sprayed concrete surface is shaped by means of the rim 4 by moving it along the concrete column up and back to the lower position. The concrete-35 column can now be dried attached to the rotation shaft 2, either in this spraying device or in a separate drying location. concrete pillar, the surface after drying, are ground by rotating the pillar about the axis 2 at the same time as the surface is ground li 90 842 3 5 grinder with a blade High cycle 6. The grinding disc in a downward direction indicated by the arrow. The concrete pillar is then cut off from the axis of rotation 2. The example shows a circular concrete-5 nip pillar, but it may just as well be angular or even more versatile. Various patterns can also be sanded on the surface.
