Definitions

  • the present invention is concerned with earth- quake proof bridges, houses and the like.
  • the present invention removes the above-mention ⁇ ed disadvantages and is characterized in that bridges and houses are provided with a yieldable base which permits the base or foundation to be shaken in a manner such that the structure supported thereby, e.g. a superhighway or a house body, will not be broken.
  • Figure 1 depicts an earthquake proof bridge.
  • Figures 2 and 3 show an earthquake proof bridge after a violent earthquake.
  • Figure 4 shows an earthquake proof house.
  • Figure 5 shows an earthquake proof house after a violent earthquake.
  • Figure 6 shows the yieldable columns after an earthquake.
  • FIG 1 there is shown an earthquake proof bridge comprising cast columns 1 each provided with a ball-shaped or pivotable end 2 which is enclosed in a socket 3 anchored in the bridge span 4.
  • each of the columns will be movable by itself, indipen- dently of the other columns.
  • each column has a pivotable end, spherical or the like, en- closed in a housing which is well anchored in the bridge span.
  • the bridge span will not be broken in an earth ⁇ quake, since this will only result in the position of each column being shifted. Since the columns are Intact insofar as they are unbroken, the bridge span will not collapse but may need to be straightened. This is achiev ⁇ ed by erecting each column to its original position.
  • the columns may be interconnected by means of hydraulic arms arranged to be yieldable, but also in a manner enabling them to be drawn back to their original positions after an earthquake. This can be controlled by sensors or detectors adapted to detect any variation in the position of the columns and to indicate that they have been returned to their original positions.
  • Figures 2 and 3 illustrate what will happen to the columns supporting a bridge span upon a powerful earthquake. They will be inclined in varying directions relatively to each other and to the ground level, so that it will be necessary to realign the bridge column and possibly also to reanchor them.
  • FIG. 4 depicts an earthquake proof house.
  • Earthquake proof buildings comprise a building foundation 9 connected to preferably four or more subjacent columns 6 each provided with a ball-shaped end or joint 7 or the like enclosed in a socket 8 which is well anchored in the building foundation 9.
  • the opposite end 5 of the column is cast in the ground 10.
  • these solumns will be able to receive and adapt themselves to the shakings involved in the earth- quake without fracture of the house foundation and there ⁇ by of the body of the house.
  • the con ⁇ sequence of an earthquake will be that the pivotable columns may have to be realigned to revert to their original positions and may also need additional strengthening.
  • Figur 5 shows an earthquake proof house with an earthquake detector D disposed at the columns.
  • the space between the columns may also be utilized as a garage or the like.
  • Figur 6 illustrates what will happen to the columns supporting a building body upon a powerful earthquake.
  • the columns are inclined in different angles relatively to each other and to the ground level. After the quake the damage will be repaired by realigning the columns and, if needed, by reinforcing them in their original position.
  • the invention as such has several purposes and objects.
  • One object of the invention is to enable new bridges to be built with yieldable columns which may move in a joint well anchored to the bridge span. Thereby the effect will be achieved that shaking will not break the columns under the pressure of the weight of the bridge span when loaded under an incorrect angle.. This results in the entire bridge span being dynamic and each column following the movements of the ground.
  • the invention may also be applied to old bridges which can be rebuilt to become earthquake proof bridges. In this case they will be provided with new columns ha ⁇ ving earthquake proof joints anchored in sockets which are well anchored in the bridge span. As the bridge is provided with columns having earthquake proof joints, the initial rigid columns may be destroyed.
  • buildings in the nature of houses or the like, they may be rendered earth ⁇ quake proof in the same manner.
  • One or more cast columns will be movably arranged in sockets well anchored in the building foundation in a manner such that all columns included therein may be moved individually from the ini ⁇ tial positions without involving fracture of the house or the columns.
  • the earthquake proof columns may be realigned to take up their initial position.
  • a vibration detector Preferably, it will be disposed close to the lower portion of a column, whereby it will set off an alarm as quickly as possible.

Abstract

Structure anti-sismique à utiliser de préférence pour la construction de ponts et d'habitations. Elle se compose d'au moins un pilier (1; 6) dont une extrémité est munie d'un joint à rotule mobile (2; 7) solidement ancré dans la structure du pont (3) ou la fondation du bâtiment (8). L'extrémité opposée du pilier est solidement implantée et coulée (5) au-dessous de la surface du sol.
