Definitions

  • the damping assembly in question can be installed in a building (for example in a multi-storey building), in particular, merely by way of non-limiting example, in order to achieve one or more of the following objects and/or advantages:
  • One advantage is reducing movements, accelerations and forces associated with the action that induces a corresponding movement between the structural elements to which the damping assembly in question is connected.
  • a friction damping assembly has been indicated that is intended for being installed in a structure between at least two structural elements that can be subjected to moving reciprocally if stressed by external actions, for example actions caused by seismic events, strong winds, violent air movements, vibrations (for example induced by machinery), etc.
  • the damping assembly 1 may be associated with the structure to increase the dissipation properties thereof and thus improve the capacity thereof to withstand the aforesaid external actions.
  • the damping assembly 1 may comprise, in particular, at least one first element 2a extending along a first longitudinal axis k1.
  • the damping assembly 1 may comprise, in particular, first friction means 5a interposed between the first element 2a and the second element 3a.
  • the first friction means 5a may be arranged, in particular, near the first rotation axis x1 and/or around the first rotation axis x1.
  • the first friction means 5a may comprise, in particular, at least one pair of abrasive surfaces in mutual contact.
  • a first abrasive surface may be arranged on one side of the first element 2a.
  • a second abrasive surface may be arranged on one side of the second element 3a.
  • the second element 3a may be, as in these embodiments, interposed between the first element 2a and the further first element 7a.
  • the damping assembly 1 may comprise, in particular, second friction means 5b interposed between the second element 3a and the third element 2b.
  • the second friction means 5b may be arranged, in particular, near the second rotation axis x2 and/or around the second rotation axis x2.
  • the damping assembly 1 may comprise, in particular, third friction means 5c interposed between the third element 2b and the fourth element 3b.
  • the third friction means 5c may be arranged, in particular, near the third rotation axis x3 and/or around the third rotation axis x3.
  • the damping assembly 1 may comprise, in particular, a fifth element 2c that is longitudinal, side by side, parallel to and coplanar with the third element 2b.
  • the fifth element 2c may be coupled with the second element 3a and with the fourth element 3b so as to define, on the whole together with the other elements, six rotation axes (defined by six hinge zones 4a, 4b, 4c, 4d, 4e, 4f) arranged in a lattice with square or rhombic links, at each of which the same number of friction means is arranged, respectively 5a, 5b, 5c, 5d, ..., etc, and the same number of prestressing means respectively 6a, 6b, 6c, 6d, ..., etc. It is possible to arrange further friction means 8a, 8b, 8c, 8d, ..., etc, in addition to the friction means 5a, 5b, 5c, 5d, ..., etc.
  • the damping assembly 1 may comprise, in particular, a sixth element 3c that is longitudinal, side by side, parallel to and coplanar with the fourth element 3b.
  • the sixth element 3c may be coupled with the first element 2a, with the third element 2b and with the fifth element 2c so as to define another three rotation axes (defined by three hinge zones) arranged in a lattice with square or rhombic links together with the other hinge zones, at each of which the same number of friction means is arranged and the same number of prestressing means. It is possible to arrange further friction means in addition to each of the aforesaid friction means.
  • Each longitudinal element 2a, 2b, 2c, ..., 3a, 3b, 3c, ..., 7a, 7b, ... can comprise, in particular, a plate-like body (lamella, foil, lath, strip, shingle, stave, slab, etc), for example made of solid wood or of a material based on wood (laminate), or of other materials (metal, plastic, cement, composite, etc).
  • the damping assembly may be used, for example, to improve the capacity of a structure to withstand external stress.
  • the damping assembly 1 may be made, as has been seen, in the shape of a panel comprising two or more layers of longitudinal elements (in particular of flat shape, for example lamellas, laths, slabs, shingles, boards, etc) arranged transversely and coupled together by several hinge zones with rotation axes that are parallel to one another arranged in a lattice with square or rhombic links.
  • longitudinal elements in particular of flat shape, for example lamellas, laths, slabs, shingles, boards, etc
  • the friction means comprises contact surfaces that have surface roughness that is relatively high in the interfaces between the various layers of the panel.
  • These contact surfaces may be surfaces of the various longitudinal elements (lamellas, laths, slabs, shingles, boards, etc) that are processed, for example, in one or more of the following modes: 1) gluing one or more sheets of abrasive paper; 2) application of one or more layers of abrasive powder (for example silicon glass) on a predistributed adhesive layer; 3) surface treatment for increasing the roughness of the surface.
  • the friction means may be pre-stressed, in particular, by a series of screw coupling means arranged in a lattice (with square or rhombic links) for assembling the layers of the panel.
  • the screw means may be arranged at the hinge zones (rotation pins) that in this case may be an integral part of the screw means.
  • the preload may be obtained, as has been seen, by one or more threads of the screw means, in which each thread may couple with a sole longitudinal element (for example an element arranged on one side of the assembly).
  • the preload may be maintained almost constant over time by using a split washer (installed on the side of the assembly opposite the side coupled with the thread) capable of compensating for possible shrinkage and transverse swelling phenomena of the longitudinal element (for example made of wood or of a material based on wood).
