Technical Field
The invention relates to a shock absorber for a steel structure building column foundation, belonging to a shock absorption part of a steel structure building.
Background
At present, steel structure buildings are developed rapidly, and steel structures are used as main structures of building frames in some low and even high-rise buildings. However, the existing steel structure building is slightly poor in earthquake transverse wave resistance, and the earthquake transverse wave is stressed due to transverse shear when the earthquake transverse wave comes, so that the earthquake resistance of the steel structure building is insufficient.
The existing shock insulation/absorption technology is a new steel structure building earthquake-resistant technology, is commonly accepted by the building industry and earthquake departments, and belongs to a new method in the third-generation earthquake-resistant aspect. It has very obvious effect on resisting earthquake damage. Theoretical analysis suggests that seismic isolation/damping techniques can reduce seismic damage by an intensity level.
The shock absorption and isolation products are divided on the basis of the structure principle, and various shock absorption products used in the global range can be divided into three types, namely a laminated rubber shock absorption support, a pendulum type damping shock absorber and a friction sliding device. At present, no matter which kind of products are widely used, because they have certain design defects and differences in quality. The functions of relieving longitudinal earthquake acting force and the problems of long-term maintenance-free durability, cost and the like are not realized.
The column foundation under the column of the hall of ancient Chinese architecture is matched with the column to realize shock absorption. Namely, the upper plane of the column foundation stone is connected with the lower end plane of the column and is placed higher than the ground, so that the effects of moisture resistance, moth resistance and durability are achieved. One of the main reasons that ancient Chinese buildings proved by time and recorded in many times of history have strong earthquake-resistant performance is that the upright posts and the foundation stones can move so as to reduce the damage of the strong force of earthquake to the buildings. Only need repair after the earthquake, through the lever power pry the stand of displacement to the positive plane of column foundation stone to reconversion can.
Disc swing bumper shock absorber (patent application number CN 201810947786.6) is a novel steel structure building damping device, and its removal through the steel ball realizes the displacement when bearing the earthquake transverse wave between the steel structure from top to bottom, can effectual reduction earthquake transverse wave to the influence that the steel constructs. The structure is suitable for light load, and for larger steel structure buildings, the size of the steel ball needs to be increased to adapt to heavier steel structure buildings. A single steel ball cannot be infinitely enlarged.

Detailed Description
The following further illustrates the specific structure of the present invention:
the invention relates to a steel structure building column foundation shock absorber, which comprises an upper connecting disc 1 and a lower connecting disc 2 as shown in figure 1. The upper connecting disc 1 and the lower connecting disc 2 are both disc-shaped structures
The upper connecting disc 1 is connected with an upper steel component, and the lower connecting disc 2 is connected with a lower steel component.
Be protruding 101 in the middle of the downside of upper portion component, protruding 101 shape is the toper, the top angle is the fillet, be indent 201 in the middle of the upper portion side of lower connection pad 2, indent 201 shape is the toper, the indent 201 fixed point is the fillet, the conical tapering of indent 201 is greater than the conical tapering of protruding 101, go up in the indent 201 of connection pad 2 is embedded to protruding 101 of connection pad 2 down of connection pad 1, the indent 201 a week of lower connection pad 2 is the plane and contacts each other with protruding 101 a week of last connection pad 1, lower connection pad 2 is equipped with seal structure on the contact surface.
