Corner seismic isolator for seismic protection of buildings

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.

1 . 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 (F) with a brick partition (P) inside, the isolator consisting of a single monobloc part ( 1 ) formed from a material more flexible than the frame (F) and than the bricks of the partition (P), 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 the other to be situated between the frame (F) and the partition (P) in a horizontal direction, the thickness of which in the direction perpendicular to the plane of the partition (P) is between 0.5 to 1.5 times the thickness of the bricks in the partition (P), with the width of the arms ( 11 ,  12 ) being equal to or greater than one third of the height of a single brick in the partition (P) and the length thereof equal to or greater than three times the width of the arm itself ( 11 ,  12 ), with the length thereof, in turn, being smaller than the corresponding dimension of the partition, characterised in that it comprises at least one insert ( 2 ), which has one end embedded in the part ( 1 ), this end having a length less than or equal to four fifths of the width of the arm itself ( 11 ,  12 ), and the other end protruding from one of the surfaces of the isolator perpendicular to the plane of the partition (P); each arm ( 11 ,  12 ) comprising at least one insert ( 2 ) perpendicular to the longitudinal direction of the corresponding arm ( 11 ,  12 ); one of every two consecutive perpendicular inserts ( 2 ) comprising one end protruding through the surface that is in contact with the frame (F) and the inserts ( 2 ) alternating with the previous ones comprise one end protruding through the surface that is in contact with the partition (P). 
     
     
         2 . (canceled) 
     
     
         3 . The isolator according to  claim 1 , characterised in that the end of each arm ( 11 ,  12 ) comprises an insert ( 2 ) placed parallel to the longitudinal direction of the corresponding arm ( 11 ,  12 ). 
     
     
         4 - 5 . (canceled) 
     
     
         6 . The isolator according to  claim 1 , characterised in that the width of at least one of the arms ( 11 ,  12 ) is larger in the area close to the joint with the other arm ( 11 ,  12 ) and is smaller in the area of the end itself. 
     
     
         7 . The isolator according to  claim 1 , characterised in that the vertical arm has 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. 
     
     
         8 . A method for installing a seismic isolator in already built frames described according to  claim 1 , characterised in that it comprises the following steps:
 Making a groove or recess in at least one corner of the partition in contact with the frame,   Housing the seismic isolator in the groove or recess,   Filling the existing gaps with masonry mortar.
