Abstract

A corner seismic isolator for the seismic protection of buildings, both new and already built, comprising at least one resistant element in the form of a frame with a brick partition inside, the isolator consisting of a single monobloc part formed from a material more flexible than the frame and than the bricks in the partition, comprising two arms arranged at a right angle, one to be situated between the frame and the partition in a vertical direction and the other to be situated between the frame and the partition in a horizontal direction, the thickness of which in the direction perpendicular to the plane of the partition is between 0.5 and 1.5 times the thickness of the bricks in the partition, with the width of the arms being equal to or greater than one third of the height of a single brick in the partition and the length thereof being equal to or greater than three times the width of the arm itself, with the length thereof, in turn, being a portion of the corresponding dimension of the partition, with the vertical arm having a length of between 0.1 and 0.5 times the height of the partition and the horizontal arm a length of between 0.1 and 0.5 times the length of the partition.

Claims

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] FIG. 1 is a schematic elevation view of the seismic isolator of the present invention in its condition of use.

[0017] FIG. 2 is a perspective view of an exemplary embodiment of the seismic isolator of the present invention.

[0018] FIG. 3 is a schematic view of an exemplary embodiment of the seismic isolator of the present invention.

DESCRIPTION OF A PREFERRED EMBODIMENT

[0019] In light of the aforementioned figures, and in accordance with the adopted numbering, one may observe therein a preferred exemplary embodiment of the invention, comprising the parts and elements indicated and described in detail below.

[0020] As shown in FIG. 1, the preferred embodiment of the seismic isolator of the present invention consists of a single monobloc part (1) comprising two arms (11, 12) arranged at a right angle, one to be situated between the frame (F) and the partition (P) in a vertical direction and another to be situated between the frame (F) and the partition (P) in a horizontal direction. In the exemplary embodiment shown in FIG. 1, the arms (11, 12) have a width somewhat smaller than the height of the bricks of the partition (P), the horizontal arm has a length ten times the width of the isolator and the vertical arm nine times the width of the isolator. This figure shows the mortar (m) placed around the monobloc part (1), which fills the gaps between it and the frame (F), and between it and the partition (13).

[0021] The exemplary embodiment shown in FIGS. 2 and 3 comprises an insert (2) placed at the end of each arm (11, 12), parallel to the longitudinal directions thereof. Likewise, it comprises in each arm (11, 12) inserts (2) perpendicular to the longitudinal direction, of which one of every two consecutive inserts (2) comprises an end protruding through the surface that is in contact with the frame (F), while the inserts (2) alternating with the previous ones comprise one end protruding through the surface that is in contact with the partition (P). In this case, the width of the arms (11, 12) is equal to the thickness thereof, and the length thereof is four times the width itself, being able to be comprised between 0.1 and 0.5 times the height of the partition in the case of the vertical arm and between 0.1 and 0.5 times the length of the partition in the case of the horizontal arm. As seen in FIG. 3 in dotted lines, the embedded length of the inserts (2) of this exemplary embodiment is two thirds of the width of the arms (11, 12). It can also be seen how the external end of all the inserts (2) protrudes from the part one sixth of the length thereof, being smaller than the width of the mortar perpend and/or bed of the partition wherein it is inserted.
