Embodiment Construction

[0057] The first example is based on Figure 9 The mechanism of "V-shaped sliding contact", which includes at least one pair of V-shaped sliding contact surfaces to establish the connection between the superstructure and the substructure of large-scale civil engineering systems, when the substructure or superstructure is subjected to one or more When external force acts, temporary relative sliding is allowed between the upper and lower structures, thereby weakening the inertial force and protecting the entire system. Because when there is a tendency to slip or has slipped between a contacting pair of surfaces, the weight of the superstructure causes a horizontal force opposing the direction of the slip. This horizontal force combined with the frictional force ensures that the support device constitutes a fixed connection under normal operating conditions and when the horizontal force caused by inertial forces is lower than the horizontal resistance caused by static friction an...

Abstract

A class of bearings, each of them can be used as a connecter to connect two parts in a structural system and as a supporter to transfer loads from one part to another, for examples, gravity of a superstructure to a substructure in a bridge or a building, or that of a machine to its foundation. While performing load transmission, it is able to reduce the transmission of transient vibrations between connected two structural parts and preserve the integrity of entire structural system; for examples, to protect a bridge's structural integrity when either an earthquake strikes its pier and foundation or a tsunami hits its superstructure or both occur simultaneously.

Description

technical field [0001] The invention discloses a device, which is characterized in that the device is a structural part used in large-scale industrial and civil construction engineering systems, such as buildings, bridges or machines and their foundations, and has at least one of the following three functions: Supports the partial weight of the system, connects different parts of the system to ensure structural integrity, transmits designed force flow between connected parts instead of gravity, and at the same time slows or isolates harmful vibrations. [0002] The engineering system, such as a bridge or a building, can basically be divided into two parts: an upper structure such as a bridge span and a bridge deck system bearing design live loads; and a lower structure, including bridge piers, pier foundations and deep foundations. The device of the present invention connects the superstructure and substructure of such engineering systems while supporting the weight of the sup...
