EARTHQUAKE ISOLATOR

Abstract

Invention; is related to isolators eliminating circular forces caused by earthquake forces acting on the building. It is placed between foundation of structures manufactured by steel construction, concrete, prefabricated structure or other methods and structure and which reduces/terminates impact of earthquakes on structures. Thus, damage to be given by earthquake to carrying elements of building is eliminated.

DETAILED DESCRIPTION OF THE INVENTION

[0057] Invention; consists of anchor rod (1), lower chassis (2), lower movable ball group (3), body (4) centering piston (5), heel (6), upper ball group (7), upper chassis (8), connection plate (9) connection sprouts (10). Body (4), comprises reinforcing pillar (4.1). The upper chassis (8) contains flag (8.1) on it.

[0058] Holes are drilled into sections on body (4) where centering piston (5) to be assembled. At least one strengthening pillar (4.1) is mounted on edges of the hole. Then centering pistons (5) are placed on body (4) and secured. Centering pistons (5) should be secured to be aligned with the vertical axis of the body (4).

[0059] Body mounting structure is placed on lower chassis (2) and mounted together rigidly. Then lower moving ball group (3) to meet the mechanical load of building is placed on lower chassis (2) according to the force distribution. Because lower moving ball group (3) is a free moving, carrying element it is deposited in a slot. Lower moving ball group (3) moves freely between heel (6) lower chassis (2).

[0060] Connection plate (9) is mounted on heel (6) where upper ball group (7) and connection sprouts (10) are secured. The prepared assembly set is mounted on lower movable ball group (3) to be coaxial with the body (4). Then the upper chassis (8) is connected to body (4) in same axis with lower chassis (2) with reinforcement struts (4.1) rigidly. To increase the strength of upper chassis (8) flags (8.1) are placed on it in a circular axis.

[0061] At least one seismic isolator facing the bottom of each carrier column will be secured on the foundation of the structure according to the ground properties with anchor bolts (1). Structure is connected to seismic isolator with connection sprouts (10). In required circumstances perennial foundation will be made on connection sprouts (10) of seismic isolators placed on foundation with specified intervals and structure will be built on this perennial foundation.

[0062] The devastating effects that is created by horizontal movements during earthquakes sterns from circular form force. So structure faces centrifugal force. This centrifugal force constitutes the devastating effects on structure. To minimize or eliminate this impact the invention provides effective protection.

[0063] The invention is used to isolate the resonance faced by structures during an earthquake. When earthquake-induced force starts to impact a structure built on seismic isolator; bottom chassis (2), body (4) and the upper chassis (8) mounted to anchored to the foundation starts to move together with the foundation. Heel (6), connection plate (9) and the connection sprout (10) tries to maintain its current position together with building. The system to provide this effect is upper ball group (7) in contact with upper chassis (8) and secured to heel (6) (freely movable within housing) and movable bottom ball group (3) located under the heel (6). Upper ball group (7) at the same time transfers momentum coming from the structure to the body (4) with heel (6). Momentum transmitted to body (4) is then transferred to foundation. Due to free movement of lower ball group (3) within the housing friction stemming from the weight of the structure during earthquake is zero. Thus horizontal deflections coming to foundation are eliminated without being transferred to structure. After the earthquake ends heel (6) may be in a position eccentric from the center of seismic isolators. Centering pistons (5) located on the body (4) provides the heel (6) and structure to take original position before the earthquake. Centering piston (5) strokes are equal and are located at equal intervals around. With equal force and speed coming to stroke mills of centering pistons (5) heel (6) is brought to center of earthquake isolators by means of centering pistons (5). Thanks to a free moving ball on tip of the cylinder deformation and friction are minimized.

[0064] Because heel (6) will move freely within body (4) during earthquake diameter difference between body (4) and heel (6) is calculated with safety criteria to meet displacement of earthquake in respect to the ground characteristics where the foundation will be established.
