Shock isolation and energy dissipation double-controlled device for reinforcement reset masonry house foundation

Abstract

The invention discloses a shock isolation and energy dissipation double-controlled device for a reinforcement reset masonry house foundation. The device comprises a plain concrete cushion layer, a lower foundation beam, an upper foundation beam, a reset reinforcement, an isolation layer and a plain concrete shear key. The lower foundation beam is manufactured above the plain concrete cushion layer, the upper foundation beam is manufactured above the lower foundation beam, and the wall is built above the upper foundation beam. Two ends of the reset reinforcement are anchored in the upper foundation beam and the lower foundation beam respectively, and a sleeve is sleeved at the middle section of the reset reinforcement to separate the concrete in the reset reinforcement from the upper foundation beam and the lower foundation beam; and the isolation layer is arranged between the upper foundation beam and the lower foundation beam to isolate the upper foundation beam from the lower foundation beam, grooves capable of mutually matched are formed between the upper surface of the lower foundation beam and the lower surface of the upper foundation beam, and the mutually-matched grooves form the plain concrete shear key. The device can improve the shock resistance and energy dissipation resistance of the structure, and reduce the damage of earthquakes.

Description

technical field [0001] The invention relates to a foundation shock-isolation-energy-consuming dual-control device of a masonry building with steel bars reset, which belongs to a foundation shock-isolation-energy-consuming dual-control device of a middle and low-rise masonry house. Background technique [0002] Structural seismic isolation system is a reasonable, effective, safe and economical shock-absorbing system. It has completely changed the way of "strengthening" the traditional structure, and adopted a new way of "softening" the structure and "overcoming rigidity with softness" to isolate earthquakes. That is to install a horizontally flexible seismic isolation device at the bottom of the building to soften the structure and reduce the stiffness, thereby prolonging the natural vibration period of the structure and reducing the seismic response of the structure. When encountering a small earthquake or gust of wind, the base isolation device is sufficient to keep the str...
