Technical Field
The invention relates to the technical field of earthquake-resistant structural systems, in particular to a self-resetting enhanced column base and a construction and installation method thereof.
Background
In recent years, due to the frequent occurrence of earthquakes and the requirement of people on modern safety standards, self-reset devices and damping and energy-consuming devices are paid attention. The earthquake-proof and earthquake-proof steel plate can not only reinforce the structure during an earthquake, but also quickly recover the normal use of the structure after a strong earthquake so as to protect the life and property safety of people. In addition, in patent publication No. CN110318479A, entitled self-resetting column base structure and its construction method, the operation mechanism of the composite combined disc spring is that when the column base tilts, the suspension plate is driven to press the spring on one side, so that the column base is self-reset by the elastic force of the pressed spring. However, we have found that the pre-stressed spring force of the spring on the other side prevents the self-resetting of the column shoe, which results in a reduction of the self-resetting capability of the composite combination spring.
Therefore, it is an urgent need of the skilled in the art to develop a reinforced column base and a construction and installation method thereof, which can make all disc spring sets be pressed in the large earthquake and make the elasticity of the spring sets be favorable for the column base to self-reset.

s1, sleeving a second disc spring set (4), two limiting base plates (5) and two high-strength nuts (6) on an anchor rod (9), applying prestress on the second disc spring set (4), welding and fixing a limiting device (3) and a cantilever plate (7), and then unscrewing the high-strength nuts (6) to enable two surfaces of the limiting base plates (5) to be stressed;
s2, welding and fixing the cantilever plate (7) and the side wall of the steel column (1), and welding a support plate (8) for supporting;
s3, sleeving a first disc-shaped spring set (16) on the top of the high-strength pull rod (2), applying prestress, and fixing by high-strength nuts on the bottom surface of the transverse stiffening rib (17);
s4, embedding a sleeve for the high-strength pull rod (2) and the anchor rod (9) to penetrate into the foundation (18), inserting the steel column (1) into a limiting groove (11) of the foundation (18), and fixedly connecting the high-strength pull rod (2) and the anchor rod (9) with a foundation embedded part (15) in the foundation (18) after penetrating through the sleeve;
and S5, filling the high-strength concrete which is easy to expand into the sleeve for fixing.
