Problems solved by technology

[0003] The existing anti-seismic devices of wooden structures are mainly reinforced around the nodes of the wooden structure, while ignoring the importance of the position of the column feet. The position of the column feet is at the weak node position when the earthquake damages. The pier reinforcement method and the chemical reinforcement method are the main methods. Although these methods can protect the column foot joints and improve the earthqu

Abstract

The invention discloses a hidden viscous damper energy-dissipation shock-absorption device for wooden structure ancient building column foots. The device comprises a cylindrical foundation stone, an annular groove with a center column as the circle center is formed in the top of the foundation stone, an annular clamping groove is formed in the annular groove, and a plurality of viscous dampers ofa same structure are annularly distributed along the annular clamping groove. An annular clamping groove steel disc is connected to the tops of the viscous dampers in a covering mode, a plurality of expansion bolts penetrate through the annular clamping groove steel disc, and the tops of the expansion bolts are wedged into a wood column above the expansion bolts. While the original appearance of an ancient building is not damaged, the damping device is additionally arranged in the foundation stone under the column, and energy of seismic waves can be effectively consumed and reduced. Double breakthroughs are achieved in the aspects of building appearance maintenance and earthquake resistance.

Description

technical field [0001] The invention relates to the field of repair and protection of ancient wooden structures, in particular to a concealed viscous damper energy-dissipating shock absorber at the foot of an ancient wooden structure, which is suitable for the earthquake and maintenance requirements of traditional wooden ancient buildings. Background technique [0002] The ancient wooden structure building is a bright pearl among the ancient buildings with Chinese characteristics. Its artistic value, scientific value and historical value are immeasurable. The distribution of ancient wooden structure buildings in our country is also extremely wide. Most of the traditional wooden structures in my country use the beam-column system as the force-bearing system, which is similar to the frame structure. The beam-column is only connected by mortise and tenon, without any iron parts. Under the action of horizontal load, the overall structure will have a large sideways movement. At t...
