Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1 to 4, a shear yield type steel pipe concrete vibration isolation support comprises an upper connecting plate 1 and a lower connecting plate 2, wherein the upper connecting plate 1 is connected with an upper building through a high-strength bolt 3, in this embodiment, a circle of high-strength bolt 3 is arranged on the upper connecting plate 1, the lower connecting plate 2 is connected with a lower building foundation through a bolt hole 21 and a corresponding bolt, in this embodiment, a circle of bolt hole 21 is arranged on the lower connecting plate 2, a variable cross-section steel pipe 4 is arranged between the upper connecting plate 1 and the lower connecting plate 2, a pouring hole 12 is reserved on the upper connecting plate 1, concrete 5 is filled in the variable cross-section steel pipe 4 through the pouring hole 12, and in this embodiment, the upper connecting plate 1, the lower connecting plate 2 and the variable cross-section steel pipe 4 are made of steel materials.
The variable cross-section steel pipe 4 is formed by stacking and connecting a plurality of weakened cross-section sections 41 and a plurality of reinforced cross-section sections 42, so that the weakened cross-section sections 41 are plastically deformed to provide horizontal displacement.
The reinforced section sections 42 and the weakened section sections 41 of the variable cross-section steel pipe 4 are alternately stacked and connected to form a trapezoidal or wavy cross section.
The variable cross-section steel pipe 4 is a rectangular or cylindrical corrugated pipe, as shown in fig. 5, that is, the variable cross-section steel pipe 4 is a cylindrical corrugated pipe, an inward concave section of the corrugated pipe is used as a weakened cross-section 41, and an outward convex section of the corrugated pipe is used as a reinforced cross-section 42.

Principle of the invention
When the support disclosed by the invention is under the action of pressure, the pressure of an upper building is borne by the concrete 5 filled in the support, and meanwhile, the peripheral variable cross-section steel pipes 4 have a certain constraint effect on the concrete 5, so that the concrete 5 is in a three-dimensional compression state, the compression resistance of the concrete 5 is obviously improved, and the support disclosed by the invention is ensured to have larger vertical bearing capacity.
When the support bears horizontal shearing force, the horizontal rigidity of the weakened section 41 of the variable-section steel pipe 4 is smaller than that of the reinforced section 42, and the horizontal displacement of the structure is mainly concentrated at the weakened section 41 under the action of an earthquake, so that the weakened section 41 generates larger horizontal displacement, the natural vibration period of the structure is prolonged, and the earthquake response of an upper building can be reduced through large deformation of the support.
