Embodiment 1

[0033] Embodiment 1: Controllable rotation and self-resetting elastic column hinge structure

[0034] Such as figure 1 , figure 2 As shown, the controllable rotation self-resetting elastic column hinge structure includes an upright frame column 1 and a shallow cup mouth column base 2 . A concave cup for receiving the frame column is provided on the top surface of the shallow cup base 2 . Corresponding longitudinal reinforcements 7 and stirrups 9 are arranged in the column body of the frame column 1 according to the stress. The bottom surface of the frame column 1 is provided with a steel bottom plate 4, on which a number of upright steel pipes 5 are welded, and the steel pipes 5 are pre-embedded in the body of the frame column 1. Each steel pipe 5 is pierced with a high-strength steel bar 6, the upper section of the high-strength steel bar 6 is anchored in the column body of the frame column 1, and the high-strength steel bar 6 has an embedded length of at least 2 / 3 column...

Embodiment 2

[0037] Embodiment 2: Realization method of self-resetting elastic column hinge

[0038] The realization method of the self-resetting elastic column hinge comprises the following steps:

[0039] (1) Fabrication of embedded parts: Cut out a rectangular steel plate according to the design shape and size of the bottom surface of the frame column. The steel plate can be a conventional steel plate of Q235 or above grade. Gas welding is used to open 1-2 holes on the four corners of the steel plate, and a vertical steel pipe is welded on the top surface of the steel plate corresponding to each hole. All the steel welds are double-sided welds. The inner diameter of the steel pipe and the hole diameter of the holes on the steel plate should be slightly larger than the diameter of the selected high-strength steel bar. After the steel plate and steel pipe are treated with antirust as a whole, they become embedded parts. The steel plate in the embedded part is placed on the bottom surfac...

Abstract

The invention relates to a controllable rotary self-resetting elastic column hinge structure and a method for obtaining a self-resetting elastic column hinge. The controllable rotary self-resetting elastic column hinge structure comprises a vertical frame column and a shallow-cup-mouth column foundation arranged on the bottom surface of the frame column. A concave cup mouth used for bearing the frame column is formed in the top surface of the shallow-cup-mouth column foundation. A steel base plate is arranged on the bottom surface of the frame column. A plurality of vertical steel tubes are welded to the steel bottom plate. The steel tubes are embedded into a column body of the frame column. A high-strength steel bar is connected into each steel tube in a penetrating mode. The upper section of each high-strength steel bar is anchored into the column body of the frame column. The lower section of each high-strength steel bar is anchored into a foundation body of the shallow-cup-mouth column foundation. According to the controllable rotary self-resetting elastic column hinge structure, a traditional frame design concept is broken through, the frame column foundation joint has high self-resetting performance, the frame column has the elastic rotation ability and the self-resetting ability, and the anti-seismic performance of the frame column is improved.

Description

technical field [0001] The invention relates to a building structure, in particular to a controllable rotating self-resetting elastic column hinge structure and a method for realizing the self-resetting elastic column hinge. Background technique [0002] The recent frequent strong earthquakes on the earth have not only caused heavy property losses, but also seriously threatened the lives of the general public. As the main places of people's production and life, the buildings are damaged in natural disasters such as earthquakes, which will bring huge losses. Therefore, it is of great significance to study the new anti-seismic system of buildings. In the existing concrete frame column or steel column structure based on ductility design, the preset ductile deformation mechanism of the section is mainly realized by the structural material of the frame column such as steel or concrete yielding to form a section plastic hinge. In the case of moderate earthquake intensity It will...
