Abstract (en)
This multi-purpose prefabricated centering consists of a main upright (1) exemplified by a tubular section, the upper end of which is threaded (3') and on which is screwed a threaded body (3) or slider, a secondary upright (4) fitted in the main upright (1) and provided with holes (5) for the coarse height adjustment of the upright (1, 4) by inserting a pin (5') in the external hole of the threaded body (3), whereas precision adjustment is achieved by acting on the slider (3), a head (6, 7) provided with a vertical semicircular plate with transverse holes (8, 9) located on an internal and an external spider, primary arms (10) provided with a hole (13) at their lower end (11) in which to fit a hinge pin (12) inserted in one of the holes (8) of the internal spider and featuring a slot (15) to block the arm by fitting the pin (14) in the hole (9) drilled in the external spider, while the primary arm 10) features at its outer end a threaded body or slider (17) provided with secondary arms (18) sliding in each primary arm (10), bearing a rod (19) at its outer end and provided with a series of holes (20) for coarse adjustment of the total length of the arms (10-18) by means of the pin (20') fitted in the hole (20) of the arm (18) on the outside of the threaded body (17), whereas precision adjustment is achieved by acting on the slider (17), including a plate (21) in flexible deformable material, the inner surface of which features a set of seats (22) in which to lodge the rods (19) of the secondary arms (18), so that all components of the centering can be used for all kinds of vaults and even for multiple-centered vaults and arches and these components may be recovered and re-used in other constructions. <IMAGE>
