<p>The straight beam profile of required length is before bending filled with the flexible reinforcement, to ensure against cracking beam is inserted between the first wheel and the second wheel and is directed into the space between the first wheel and the third wheel, the third wheel position is adjusted so that the bending beam corresponds to the desired curvature of the beam, then through the rotation of the wheels and the friction between the beam and the wheels is the beam retracted between them and is attached between the first wheel and the third wheel with the required radius of curvature. Device for carrying out the method comprises a housing (11) which is on the back fitted with the wheels (12), ensuring the mobility of the device, inside the housing (11) there are driving and gear means, which drive the rotary shaping wheels (13, 14, 15) located on the top side (16) of the housing (11), the first wheel (13) and the second wheel (14) are fixed in a stable position dependent on the diameter of the wheels (13, 14), the third wheel (15) is adjustable to other positions, depending of the produced radius of curvature of the beam, the upper side (16) of housing (11) is provided with a full-open cover (17) as well as a panel (18) with the controls for the movement checking and for the wheels readjustment (13, 14, 15).</p> |
