Definitions
- the present invention relates to a vibration damper device for prefabricated warehouses and similar buildings.
- the present invention relates to a vibration damper device for prefabricated warehouses in reinforced concrete, to which the following description will make explicit reference without thereby losing in generality .
- prefabricated warehouses in reinforced concrete consist essentially of a reinforced-concrete, large horizontal roof which rests on a series of vertical pillars also in reinforced concrete.
- the horizontal roof consists of a series of reinforced-concrete long main beams generally having an I-shaped, L-shaped, T-shaped or inverted T-shaped cross section and which are arranged in horizontal position and parallel and facing or aligned to one another, resting on the upper ends of the pillars; and of a series of reinforced-concrete covering crossbeams that are arranged in horizontal position and one parallel and side-by-side to the another, crossways and astride two immediately adjacent main beams, so as to rest with the two ends on the main beams and be locally perpendicular to said main beams.
- the horizontal roof can be assembled using prefabricated reinforced-concrete main beams and covering crossbeams .
- the modular structure described above does not offer a high resistance to undulatory-type seismic events .
- Patent application WO2014/147598 discloses a vibration damper device which is structured so as to anchor the ends of the covering crossbeam to the underlying main beam, and is also able to deform in an elastoplastic manner to allow and dampen any movements of the crossbeam parallel to the longitudinal axis thereof.
- Aim of the present invention is to improve performances of the vibration damper device described in patent application WO2014/147598.
- a vibration damper device for prefabricated warehouses and similar buildings as defined in claim 1 and preferably, though not necessarily, in any of the dependent claims.

- FIG. 4 is a partially-exploded perspective view of the vibration damper device shown in Figure 3.
- reference numeral 1 denotes as a whole a vibration damper device specifically structured to be able to connect/fix the axial ends of the covering crossbeams of the roof of a reinforced -concrete warehouse 100 or similar building to the main beams immediately underneath, and to dissipate the energy released onto the warehouse roof 100 during a seismic event .
- the warehouse 100 is basically made up of a series of load-bearing pillars 101 (only one pillar is shown in Figure 1) which rise from the ground in a substantially vertical direction and are preferably, though not necessarily, made of reinforced concrete; and of a large, substantially flat, covering roof 102 which extends horizontally at a predetermined height from the ground, resting on the top of the pillars 101.
- the covering roof 102 is made up of a series of long main beams 103 (only one main beam is shown in Figures 1, 2 and 3) which are arranged in a substantially horizontal position, spaced one beside the other, in such a way as to be in pairs locally substantially parallel and facing each other, and which are arranged resting on the upper ends of the load-bearing pillars 101, in such a way as to extend astride two or more adjacent load-bearing pillars 101 at a predetermined height from the ground; and by a series of covering crossbeams 104 which are arranged in a substantially horizontal position and one flanked/ adjacent to the other, straddling two adjacent main beams 103, in such a way as to rest with the two axial ends 104a on same main beams 103.

- main beams 103 may also consist of reinforced-concrete section-bars with T-shaped, L-shaped, double T-shaped, inverted T-shaped cross-section and similar.
- the covering crossbeams 104 instead, preferably consist of as many prefabricated straight section-bars in prestressed reinforced concrete, which preferably, though not necessarily, have a substantially double T-shaped cross-section, and are structured so as to be able to rest with the two axial ends 104a directly on the side wings or shelves 103a of the main beams 103.
- the warehouse 100 is preferably provided with a vibration damper device 1 at each of the two axial ends 104a of each covering crossbeam 104 of the covering roof 102.

- vibration damper device 1 It is lastly clear that modifications and variations may be made to vibration damper device 1 without however departing from the scope of the present invention.
- the deformable connecting member 5 may lack the support plate 24, and the U-shaped rod or rods 27 have a first end welded on the body of the movable slider 26, and a second end welded directly onto the plate-like portion 9 of the intermediate floating element 4, i.e. on the vertical flat plate 20.
- the deformable connecting member 6 may lack the support plate 28, and the U-shaped rod or rods 31 have a first end welded on the body of movable slider 30, and a second end welded directly onto the plate-like portion 13 of intermediate floating element 4, i.e. on the horizontal flat plate 21.
