Abstract:
An antiseismic supporting device (1) for a building structure, the supporting device (1) having a cup-shaped fixed body (3) loosely housing a movable body (6) to define an annular chamber (9) between an inner lateral surface (10) of the fixed body (3) and an outer lateral surface (11) of the movable body (6); the annular chamber (9) is filled with a viscous substance (12) and is bounded and sealed at the top by an annular cover (13) fitted to the fixed body (3); and the movable body (6) houses a connecting member (18) projecting from the movable body (6) through a central hole (19) in the cover (13).
Abstract:
Protective means are disclosed, consisting of continuous elements (2), placed beneath the lower strip of a barrier (1 ), which continuously absorb the energy due to the impact of a motorcyclist against said barrier. A protective element (2) preferably presents, in section, two V-shaped parts (5, 6) opposite each other and joined by a flat central part (7) (preferably) at right angles to the road surface, the end portions (10) of the protective element (2) being preferably bent so as to be parallel to said central part (7). Two adjacent protective elements (2) are joined to each other by an element (8) shaped like said central part (7) and pushed into the two adjacent protective elements (2) and by at least one plate (9) fixed to a supporting post (4) and to the terminal portions ( 10) of the two protective elements (2).
Abstract:
A method of raising a building structure (1), resting on a supporting body (2; 28), with respect to the supporting body (2; 28), the method including forming a foundation structure (3) for supporting the building structure (1) and having a number of through holes (4), and a number of connecting members (5; 11), each fixed to the foundation structure (3) close to a respective hole (4); inserting through each hole (4) a pile (6) having a bottom end (8) resting on the supporting body (2; 28), and a top end (16) projecting from the hole (4) ; fitting to each pile (6) a respective thrust device (15), which rests at one end on the top end (16) of the pile (6) and is secured at the other end to the corresponding connecting member (5; 11); and statically applying a respective thrust on each pile (6) by means of the respective thrust device (15) to raise the building structure (1) with respect to the supporting body (2; 28).
Abstract:
A method of raising a building (1) with respect to the ground (2); the method including the steps of : forming a mat (7) having a number of through holes (12); inserting a foundation pile (9) through each hole (12); fitting each foundation pile (9) with a lifting device (11); exerting thrust on the foundation piles (9) by means of the lifting devices (11) to raise the building (1) with respect to the ground (2); and fixing each foundation pile (9) axially to the mat (7) once the building is raised; the lifting devices (11) are divided into three equivalent, symmetrical, independent work groups; and the lifting devices (11) of one work group at a time are activated simultaneously, so that the building (1) is raised isostatically, by simultaneously activating the lifting devices (11) of one work group at a time, while the lifting devices (11) of the other two work groups are left idle.
