Problems solved by technology

In actual use, if the sliding plate 15 and the friction plate 16 in the aforementioned bolted connection structure are dissimilar metals, the difference in ionization tendency will inevitably lead to galvanic corrosion, and the contact surface may rust
Rust will cause the coefficient of friction to change, which in turn will lead to problems such as not being able to obtain the specified friction force and damping effect
In addition, the price of disc spring washers as an additional means is relatively high, and the use of multiple layers will increase the thickness, and the increase in diameter will cause problems such as construction difficulties.

Abstract

The invention relates to a screw connection structure and a damper structure. In the invention, elastic materials and pressure plates are arranged on the outside of the overlap section of plates for building structure, a pulling force is inducted into screws which run through the elastic materials, at least one nonferrous metal plate or composite ceramic plate is inserted into the plates for building structure, and at least the peripheral surface of the surface of the nonferrous metal plate or the composite ceramic plate caught between the steels is carried on waterproof processing. The invention also applies the screw connection structure in the damper structure. The invention can keep a friction coefficient stable by increasing the friction coefficient to save screws, and lower cost and simple structure are realized.

Description

technical field [0001] The present invention relates to a bolted structure of a structure and a damper structure using the bolted structure. Background technique [0002] The structure of the structure uses high-strength bolts between the steel plates to realize the current bolt connection, which usually transmits external force through friction, without considering the sliding of the friction surface. However, with the development of technology in recent years, sliding is allowed and energy is absorbed by sliding (refer to Japanese Patent Document 1: Japanese Patent Application Publication No. 08-193635; Japanese Patent Document 2: Japanese Patent Application Publication No. 2001-336560), and sliding is allowed. And it can improve the coefficient of friction (refer to "High-power Boruto friction すべり joint に 关 する research, その1. ァルミニゥム alloy plate を folded material に using レた joint elements 実験" Japan Institute of Architecture Department of Tectonics, No.537, 2003.11) The bol...
