Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of adjustable support for base isolation reinforcement, including lower support base 1, lower support base 1
Including lower supporting steel plate 1-2, lower supporting steel plate 1-2 is rectangle, and the thickness of lower supporting steel plate 1-2 is 20 millimeters.Lower supporting steel
The lower surface of plate 1-2 is equipped with rubber spacer 1-1, and the thickness of rubber spacer 1-1 is 10 millimeters, rubber spacer 1-1 increase supports
With the contact area of concrete component, support is made to be fitted closely with beam, flexible contact, while avoiding because there is concentrated stress pressure
Bad concrete.Lower supporting steel pipe 1-4 is vertically welded in the upper surface of lower supporting steel plate 1-2, and the height of lower supporting steel pipe 1-4 is fixed
It it is 350 millimeters, lower supporting steel plate 1-2 welds two ribbed stiffener 1-3 in the both sides lower supporting steel pipe 1-4, ensures stability of strutting system.Under
The upper port level of supporting steel pipe 1-2 is welded with lower nut 1-5, and lower nut 1-5 and the screw thread inside lower supporting steel pipe 1-4 are equal
The trapezoidal thread for being 30 degree for angle of thread.
The excircle of the upper and lower part of column 2 is machined with lower screw thread 2-1 and upper screw thread 2-2, lower screw thread 2-1 and upper screw thread
It is 30 degree of trapezoidal thread that 2-2, which is angle of thread, and lower screw thread 2-1 and upper screw thread 2-2's is oppositely oriented, and lower screw thread 2-1 is left-handed spiral shell
Line, upper screw thread 2-2 are right-handed thread.The lower part of column 2 and lower supporting steel pipe 1-4 and lower nut 1-5 coordinate, screw pair only by
There is self-locking performance, the lower end of column 2 to be placed in lower supporting steel pipe 1-4, the material of column 2 is steel pipe in the case of to xial feed.
The middle part of column 2 is welded with lateral rotating handle 3, and rotating handle 3 is two or four, and rotating handle 3 is arranged symmetrically, rotating handle 3
Material is steel pipe, and the height of the present embodiment is adjusted in the rotating handle that different length is inserted into rotating handle 3.
The top of column 2 is equipped with upper support seat 4, and the structure of upper support seat 4 is identical as lower support base 1.Lower support base 1,
Upper support seat 4 and column 2 are combined into the support construction lifted in an axial direction.The present embodiment can bear ultimate load
1000KN, the height of the column 2 of calculating are 1440 millimeters, and composition shores structure and can be in bearing height by rotating handle
It is adjusted in 1500 millimeters to 1800 millimeters, column 2 can be replaced, to be applicable in and the Seismic Isolation of Isolation Layer of different floor heights.When every
When shaking high increase layer by layer, the height that fine steel tube is determined by shoring the ultimate load undertaken is recalculated.It is being born to ensure to shore
Still there is larger xial feed stability, design screw pair to have self-locking property.
The present embodiment is symmetrically used will cut off frame column both ends at work, first by the lower support base 1 of the present embodiment,
