Embodiment Construction

[0020] The hyperboloid spherical shock-absorbing and isolation bearing is a new type of bearing formed on the basis of ordinary spherical bearings, replacing the plane friction pairs with large-radius spherical friction pairs, and setting shear bolts. It is mainly used for bridges and other buildings with seismic requirements.

[0021] Such as figure 1 As shown in , the hyperboloid spherical shock-absorbing and isolation bearing mainly consists of an upper seat plate (6), a middle seat plate (5), a lower seat plate (8), a spherical stainless steel slide plate (3), a PTFE slide plate (4), an anti- It is composed of several parts such as shear bolt (1), limit ring (2) and dustproof sealing skirt (7). The concave spherical surface of the upper seat plate (6) is welded and covered with a spherical stainless steel slide plate (3), and the outer side of the concave spherical surface of the upper seat plate is fixedly connected to the limit ring (2) by shear bolts (1). The upper co...

Abstract

A spherical shock absorption and shock isolation support base with double curved surface is prepared as welding stainless steel slide plate closely sticking on spherical surface on concave spherical surface of top base plate, firm-joining external side of concave spherical surface on top base plate with space ring through shearing bolt, inlaying Teflon slid plate on top convex surface of middle base plate, welding said stainless steel slide plate on bottom convex surface of middle base plate and inlaying Teflon slide plate on concave spherical surface of bottom base plate.

Description

Technical field: [0001] The invention relates to an anti-seismic support structure and device for bridges and other buildings, which is a hyperboloid spherical anti-seismic support. Background technique: [0002] In the design of bridges and other building structures, the impact of earthquakes on engineering structures is often considered. Bearings, as important components of bridges and other building structures, not only transfer loads from the upper part of bridges and buildings to the lower structure, absorb rotation and displacement, but also have a certain effect of shock absorption and isolation. [0003] At present, domestic anti-seismic devices used for bridges and other buildings mainly include lead rubber anti-seismic bearings, polyurethane spring ball bearings and large friction coefficient anti-seismic bearings, etc., all of which have deficiencies. [0004] Lead-core rubber anti-seismic bearings will gradually be eliminated due to poor durability, small bearin...
