Definitions

  • the present invention relates to a seismic isolator for the construction of buildings.
  • the seismic devices known to date are of * two distinct types: they are either based on a possibility of sliding with friction allowing a limited displacement (Cf patents FR 86 10780 and FR 88 00237 of the same inventor), or designed from elastomer studs, often fretted, the distortion of which is used.
  • the movement of the building is not amortized and the significant lateral movements can cause extremely hard shocks which can be the cause of ruptures of the earthquake-proof device, natural or, see their characteristics evolving over time, which logically should lead to their periodic replacement.
  • these devices do not make it possible to control the amplitude of the movements due to the earthquakes.
  • the device according to the present invention eliminates all these drawbacks.
  • Figures 1 and 2 show in perspective the upper and lower elements, separated.
  • Figures 3 »4 and 5 show cross sections of three versions of the assembled device.
  • FIGS. 1 to 5 consists of an upper element 1 in the form of a cylindrical cap with a flat bottom, the hollow part of which is directed downwards, integral with the superstructure of the building, with a stud or truncated cone 2 secured to the bearing surface, and to one or two damping rings 3, 3 'connected to one or two elements 1, 2 and located in an annular space 4 formed between the lower truncated cone and the upper cap 1.
  • the lower stud fixed on the foundations.
  • An intermediate space 4 separates these two elements.
  • the lower element 2 has at its base a horizontal friction plate 7 on which the lower edge 10 of the upper element 1 rests.
  • the angles 8, 9 of the side wall 16 of the stud 2 with its upper section 6 and with the plate 7 are rounded to avoid breaking initiations and a scraping effect during lateral displacements.
  • the damping crown 3 is secured to the internal side wall 11 of the upper element 1 while the crown 3 'is secured to the side wall 16 of the lower stud 2.
  • These two crowns can be replaced by a single one, secured to the side walls 11, 16 of the upper and lower elements, or of one of the two, and filling the entire intermediate annu ⁇ space 4.
  • the intermediate space 4 may be a few centimeters or exceed several tens of centimeters and adapt to the size of the building to be protected.
  • the size of the contact surfaces 10, 6 of the upper 1 and lower 2 elements can be adapted to each type of construction.
  • All the parts of the device are made of rot-proof material and with characteristics stable over time, preferably polyurethane.
  • the material used must have a shore A hardness greater than 90, a resilience greater than 40%, a tensile strength greater than 50 MPa and an abrasion resistance greater than 55 mg / mm, while for damping crowns 3, 3 ′, shore A hardness must be less than 50, resilience less than 5%, elongation at break greater than 500% and shock absorption greater than 95
