Abstract

A production method for fabricating a concrete pillar or beam, in which method the concrete mix is sprayed against the wall of a mold (1, 2, 3, 4, 5) having a predetermined shape, after which the concrete surface is smoothed by levelling. The concrete surface is levelled with the help of a surfacing disc (6), whereby the pillar or beam is rotated so as to place one side of the pillar or beam at a time facing the surfacing disc so that the pillar or beam achieves a section of a square, rectangle, pentagon, hexagon, or a similar forn.

Description

80400 BETONIPILARIN TAI -PALKIN VALMISTUSMENETELMÄ Tämän keksinnön kohteena on betonipilarin tai -palkin valmistusmenetelmä, jossa betonimassa ruiskutetaan määrätynmuo-toista muottia vastaan, jonka jälkeen betonipinta tasoitetaan .80400 A METHOD OF MANUFACTURING A CONCRETE PILLAR OR BEAM The present invention relates to a method of manufacturing a concrete pillar or beam in which a concrete mass is sprayed against a predetermined mold, after which the concrete surface is leveled.

Esimerkiksi suomalaisissa patenttihakemuksissa 872244 ja 872245 on esitetty tämäntapaisia valmistusmenetelmiä. Keksinnön tarkoitus on edelleen kehittää tätä menetelmää. Keksinnön mukaiselle menetelmälle on tunnusomaista se, että betonipinta tasoitetaan hiertokiekon avulla kääntämällä pilaria tai palkkia yksi sivu kerrallaan hiertokiekkoon nähden siten, että saadaan poikkileikkauksessa neliö, suorakaide, viisikulmio, kuusikulmio tai muu sentapainen pilari- tai palkkimuoto. Keksinnön avulla saadaan näinollen ulkomuodoltaan kauniin näköisiä pilarirakenteita, jotka onttoudensa johdosta ovat helposti käsiteltävissä ja kuljetettavissa. Vaikkakin betoni-pilari muodostuu kuoresta, on sen puristuslujuus useimmissa tapauksissa riittävän hyvä. Tarpeen vaatiessa betonipilari tai -palkki voidaan täyttää betonimassalla.For example, Finnish patent applications 872244 and 872245 disclose such manufacturing methods. It is an object of the invention to further develop this method. The method according to the invention is characterized in that the concrete surface is smoothed by means of a friction disc by turning the column or beam one side at a time relative to the friction disc so as to obtain a square, rectangle, pentagon, hexagon or other similar column or beam shape in cross section. The invention thus provides column structures with a beautiful appearance which, due to their hollowness, are easy to handle and transport. Although the concrete pillar consists of a shell, its compressive strength is good enough in most cases. If necessary, the concrete column or beam can be filled with concrete mass.

Keksinnön eräälle sovellutusmuodolle on tunnusomaista se, että muotti on pystyakselinsa ympäri kierrettävissä ja lukittavissa ruiskutusta ja hiertämistä varten. Näinollen saadaan hyvin nopealla menetelmällä tasaisesti valmistettu betoni-pilari, joka ruiskutuksen ja hiertämisen jälkeen viedään kuivumaan ja kovettumaan.One embodiment of the invention is characterized in that the mold can be rotated and locked about its vertical axis for spraying and grinding. In this way, a uniformly prepared concrete column is obtained by a very fast method, which, after spraying and grinding, is taken to dry and harden.

Keksinnön eräälle toiselle sovellutusmuodolle on tunnusomaista se, että muotti sijoitetaan vaaka-asennossa olevaan kääntölaitteeseen ja kääntölaitteen avulla käännetään palkkia tehtäessä kolme neljästä sivusta betoniruiskuun ja hiertokiekkoon päin siten, että saadaan U-muotoinen palkkikuori. Näinollen saadaan palkkikuori, jolla on määrätynlainen taivu- 2 80400 tuslujuus ja jota voidaan edelleen tarpeen mukaan raudoittaa ja täyttää betonimassalla asennuspaikalla.Another embodiment of the invention is characterized in that the mold is placed in a horizontal turning device and the turning device is used to turn three of the four sides towards the concrete sprayer and the grinding disc to make a U-shaped beam shell. In this way, a beam shell is obtained which has a certain bending strength of 2 80400 and which can be further reinforced and filled with concrete mass at the installation site as required.

Keksinnön eräälle sovellutusmuodolle on vielä tunnusomaista se, että muotin runkorakenne tehdään kiertämällä muovia, ohutta peltiä tms. materiaalia pitkänomaisten tankojen ympäri siten, että saadaan poikkileikkauksessa halutunmuotoinen muotti rakenne. Muotti rakenne varustetaan vielä esimerkiksi verkkomaisella raudoituksella, johon ruiskutettu betonimassa tarttuu hyvin, jonka jälkeen hierto tapahtuu.Another embodiment of the invention is characterized in that the frame structure of the mold is made by wrapping plastic, thin sheet metal or similar material around the elongate bars so as to obtain a mold structure of the desired shape in cross section. The formwork structure is further provided, for example, with a mesh-like reinforcement, to which the sprayed concrete mass adheres well, after which friction takes place.

Keksintöä selostetaan seuraavassa esimerkkien avulla viittaamalla oheisiin piirustuksiin, joissaThe invention will now be described by way of example with reference to the accompanying drawings, in which

Kuviot 1 ja 2 esittävät poikkileikkauksessa kuusikulmion muotoisen pilarin valmistusmenetelmää.Figures 1 and 2 show in cross-section a method of manufacturing a hexagonal column.

Kuviot 3-8 esittävät U-muotoisen palkkirakenteen valmistusmenetelmää.Figures 3-8 show a method of manufacturing a U-shaped beam structure.

Kuvio 9 esittää valmiin palkkirakenteen poistoa kääntölait-teesta.Figure 9 shows the removal of the finished beam structure from the turning device.

Kuviot 10-12 esittävät poikkileikkauksessa erilaisia muotti-rakenteita.Figures 10-12 show different cross-sectional mold structures.

Kuviot 13-17 esittävät riippuvan pystypilarin valmistusmenetelmää.Figures 13-17 show a method of manufacturing a hanging vertical column.

Valmistusmenetelmässä ruiskutetaan betonimassa määräntynmuo-toista muottia 1, 2, 3, 4, 5 vastaan, jonka jälkeen betonipinta tasoitetaan. Betonipinta tasoitetaan hiertokiekon 6 avulla kääntämällä pilaria tai palkkia yksi sivu kerrallaan hiertokiekkoon 6 nähden siten, että saadaan poikkileikkauksessa halutunmuotoinen pilari- tai palkki rakennelma.In the manufacturing method, the concrete mass is sprayed against a second mold 1, 2, 3, 4, 5, after which the concrete surface is leveled. The concrete surface is leveled by means of the friction disc 6 by turning the column or beam one side at a time relative to the friction disc 6 so as to obtain a column or beam structure of the desired shape in cross section.

Kuvioissa 1 ja 2 sekä 13-17 on muotti pystyakselinsa ympäri kierrettävissä ja lukittavissa ruiskutusta ja hiertämistä varten. Kuvioissa 3-9 on muotti 2 sijoitettu vaaka-asennossa olevaan kääntölaitteeseen 7 ja kääntölaitteen avulla käännetään palkkia tehtäessä kolme neljästä sivusta betöniruiskuun ja hiertokiekkoon päin siten, että saadaan U-muotoinen palkkikuori. Palkkikuori ja muotti poistetaan nuolen 8 osoittamalla tavalla kääntölaitteesta 7. Kuvioissa 10 ja 13 muodostuu muotin runkorakenne ohuesta tankojen 9 ympäri kierretystä muovista. Tangot 10 ja lanka 11 muodostavat verkko-rakenteen, johon betonimassa tarttuu. Kuviossa 11 muodostuu muotti kulmaan taivutetuista pelleistä 4.In Figures 1 and 2 and 13-17, the mold is rotatable and lockable about its vertical axis for spraying and grinding. In Figures 3-9, the mold 2 is placed in a horizontal turning device 7, and the turning device is used to turn three of the four sides towards the concrete syringe and the grinding disc so that a U-shaped beam shell is obtained. The beam shell and the mold is removed as indicated by the arrow 8 of the turning device 7. Figures 10 and 13 consists of a mold body structure of a thin rods 9 wound around the plastic. The bars 10 and the wire 11 form a mesh structure to which the concrete mass adheres. In Fig. 11 the mold is formed of sheet metal 4 bent at an angle.

Kuviossa 12 muodostuu muotti kulmaraudoista 12 ja pitkänomaisista peltiliuskoista 3.In Figure 12, the mold consists of angle irons 12 and elongate sheet metal strips 3.
