Betonipilarin 1 valmistus tapahtuu seuraavasti. Muottiin 2, 3 asetetaan keskityselimet 4, jotka ovat joko'läpimeneviä, putkia tai mahdollisesti vain betonipilarin päihin tulevia putkenpätkiä tai akselitappeja. Keskityselimen 4 ympäri so-5 vitetaan raudoitus 5, joka muodostuu betonipilarin akselin suuntaisista akseleista ja näiden ympäri kierretystä teräs -langasta. Muottiin 2, 3 valetaan betonimassa 6, joka saa kovettua ja kuivua. Kuviossa 3 olevassa sovellutusmuodossa irrotetaan betonielementti sahaamalla betonipilarit irti 10 toisistaan. Sahausraot on merkitty numerolla 7. Betonielementti keskitetään tämän jälkeen betonisahausyksikköön 8. Betonielementti sahataan tämän jälkeen siten, että saadaan poikkileikkauksessa halutun muotoinen pilari. Kuvioissa 7-11 on esitetty poikkileikkauksessa muutamia erilaisia muotoja. 15 Kuviossa 11 oleva betonipilari on varustettu urilla 9, joihin seinäelementtilevyt on sovitettavissa. Kun betonimassaan vielä asetetaan kiviä, joiden halkaisija on 30-100 mm siten, että sahauksen yhteydessä kivet leikkautuvat halki, niin saadaan kaunis koristepinta.The concrete column 1 is manufactured as follows. The centering members 4 are placed in the mold 2, 3, which are either through-pipes, pipes or possibly only pipe sections or shaft pins coming to the ends of the concrete column. A reinforcement 5 is formed around the centering member 4, which consists of axes parallel to the axis of the concrete column and a steel wire wound around them. A concrete mass 6 is poured into the mold 2, 3, which is allowed to harden and dry. In the embodiment in Figure 3, the concrete element is removed by sawing the concrete pillars 10 apart. The sawing slots are marked with the number 7. The concrete element is then centered in the concrete sawing unit 8. The concrete element is then sawn so as to obtain a pillar of the desired shape in cross section. Figures 7-11 show a few different shapes in cross section. The concrete column in Fig. 11 is provided with grooves 9 into which the wall element plates can be fitted. When stones with a diameter of 30-100 mm are still placed in the concrete mass so that the stones are cut through during sawing, a beautiful decorative surface is obtained.
