Embodiment Construction

[0027] The following is attached figure 1 - attached Figure 7 , to further describe the specific embodiments of the present invention.

[0028] During earthquake action, the upper sliding plate (1) moves with the superstructure, the lower sliding plate (3) moves with the ground, and the middle sliding block (2) slides. When the displacement of the slider (2) reaches a certain range, the slider (2) contacts the deceleration ring (5), and continues to slide with the deceleration ring (5), and the surrounding springs (6) due to the movement of the deceleration ring (5), Some are stretched and some are compressed, all store the potential energy of the spring, and as the displacement of the deceleration ring (5) increases, the potential energy of the spring and the spring reaction force increase; when the displacement is further expanded, the deceleration ring (5) When the collision touches the TMD (7), the TMD (7) structure exerts energy dissipation and damping effects to reduc...

Abstract

A multi-directional anti-pulling self-resetting friction mount based on TMD belongs to the field of bridge and building engineering. The mount comprises an upper slide plate, a lower slide plate, a sliding block, an outer baffle plate, a TMD, a spring, a speed reduction ring and a connecting post. A mechanical locking structure is provided between the slide block and the upper and lower sliding plates, so that the slide block has the drawing resistance function;, a spring, a speed reduction ring and a TMD are arranged between that out baffle plate and the slide block, the speed reduction ringis used for ensuring the cooperative action of a plurality of spring, and the TMD is fixed on the inner side of the out baffle plate, so that the bearing has a powerful energy dissipation function; the sliding surface between the slider and the upper and lower slide plates is spherical, the slider can slide freely in the horizontal plane, and the residual displacement of the slider can be eliminated and self-reset by relying on the gravity and the spring reaction force. The anti-pulling system can resist the vertical displacement of the superstructure caused by earthquake or accidental load.

Description

technical field [0001] The invention belongs to the fields of bridge engineering and construction engineering, and in particular relates to a shock-absorbing and isolating support with pull-out resistance requirements for bridge engineering and construction engineering. Background technique [0002] In recent years, as my country is located in the Eurasian seismic belt and the circum-Pacific seismic belt, 41% of my country's land area and more than half of the cities are located in areas with an earthquake basic intensity of 7 degrees or above, and areas with an earthquake intensity of 6 degrees or above account for 79% of the country's land area. %. For bridge engineering and construction engineering in strong earthquake areas, structural seismic capacity and post-earthquake recovery capacity have become important indicators for testing structural functions. [0003] The shock-absorbing and isolating bearing is an important component of the structure's earthquake resistance...
