High-pressure transmission type viscous damping wall

Technical Field

The invention relates to the technical field of structural shock absorption, in particular to a high-pressure transmission type viscous damping wall.

Background

In recent years, major earthquakes frequently occur, and the destructiveness of the earthquakes and secondary disasters caused by the earthquakes seriously threaten the life safety of people. With the development of times, the economic level of China is rapidly developed, buildings with high-rise, super high-rise and special structures are more and more, the requirement on the earthquake resistance of our house buildings is higher and higher, and when an earthquake occurs, the damping wall can consume most earthquake input energy, so that the integral structure of a house is protected, and the damage of the earthquake to the house is reduced.

The traditional viscous damping wall dissipates vibration energy through viscous force generated by a damping medium and a damping steel plate. The produced damping force size of steel sheet of traditional viscous damping wall is relevant with the material of damping medium, damping medium material's viscous property's good or bad direct can influence the power consumption performance of damping wall, traditional viscous damping wall is through adding the bigger damping medium of viscidity ratio in the wall body inside, insert a steel sheet in the wall body, the upper end of steel sheet is connected with the superstructure roof beam of wall body, it is interim when the earthquake comes, the motion of superstructure roof beam makes the steel sheet carry out the side-to-side movement in the wall body that is full of viscous damping medium, the produced viscous force in viscous damping medium and steel sheet surface can consume the energy that the earthquake produced, reach the effect of energy dissipation shock attenuation. However, the method mainly depends on the viscous force between the surface of the steel plate and the damping medium, the container cannot generate high pressure, the damping force generated under the action of large shock is insufficient, and the contact surface of the shear steel plate and the damping wall is in a long strip shape in order to ensure that the shear steel plate moves in the damping wall, so that the sealing of the shape is difficult. If the sealing treatment is not good, the damping medium may overflow, and the magnitude of the viscous force generated by the steel plate and the damping medium is affected.

Wumeiliang and Qiancaoru introduce a common viscous damping wall in the article of research and engineering application of the viscous damping wall, the structure of the wall comprises an inner steel plate, an outer steel plate and viscous damping media, the outer steel plate is connected with an upper structural beam, and a large viscous force exists between the surface of the inner steel plate and viscous materials, so that the damping force is generated, but the sealing of the inner steel plate and the upper end of the wall body is difficult to process, and the viscous liquid cannot overflow in the movement process of the steel plate, in addition, the method mainly depends on the viscous force generated by the surface of the steel plate and the viscous materials, and the interior of a container has no high pressure, so the generated damping force is not large. Therefore, the device has defects in structure and design and can not meet the requirements of modern production. But these shortcomings have been solved effectively to high pressure transmission formula viscous damping wall, at first the rotation axis is circular with the wall contact surface, it is very convenient to seal processing, can guarantee that the damping medium in the enclosure can not spill over, in addition cut at the shear plate and open the damping hole on the shear plate of tip, when shear plate and tip shear plate move along the horizontal direction at the time of, because the tip shear plate extends to enclosure box inner wall upper portion, the damping medium can be preferentially passed from the damping hole, produce the efflux, in damping medium motion process, the enclosure box can produce the high pressure, can produce bigger damping force, thereby more effective reduction earthquake input energy.
