Embodiment Construction
[0027]The lead-enclosed bearing that is layered and continuously restrained by hoops includes a bearing base 1 that supports engineering structures. The bearing base 1 is made of several steel plate layers 2 and rubber bonding layers 3 alternately stacked up and down. Yes, the support base 1 is provided with at least one vertical hole, and there are several restraining steel hoops 4 that are closely stacked up and down and fit closely with the hole. The restraining steel hoop 4 is a closed ring structure, and the restraining steel The inner ring wall of the hoop 4 has an arc-shaped structure, the vertical thickness of the restraining steel hoop 4 is greater than the thickness of the rubber bonding layer 3, and the upper surface of the uppermost restraining steel hoop 4 is located between the upper and lower end surfaces of the uppermost steel plate layer 2, The cavity inside the constraining steel hoop 4 is filled with an enclosing lead body 5 that fits closely with it.
