Description

Combined friction pendulum support

Technical Field

The utility model relates to the technical field of building seismic reduction and isolation engineering, in particular to a composite friction pendulum support.

Background

The friction pendulum type support is widely applied to the shock absorption and insulation of the existing building and bridge engineering. The conventional friction pendulum support is characterized in that the spherical surface of the biconvex spherical crown is matched between the upper support plate and the lower support plate, all parts are mutually attached and rotated and mutually slide, so that the continuous bearing, displacement and shock absorption and insulation functions of the support are realized. When an earthquake occurs, the support can slide in all directions, the self-vibration period of the upper structure is prolonged by using a simple pendulum mechanism, so that the transmission of earthquake force to the upper structure is reduced, part of earthquake energy is dissipated by using friction damping during sliding, the earthquake reaction of the structure is reduced, and the safety of the structure is protected.

The conventional friction pendulum base generally adopts a compound pendulum form, and both the upper surface and the lower surface have sliding displacement, so that compared with a simple pendulum structure in which the upper plate and the lower plate are arranged by utilizing a structure with double sliding and sliding displacement, the friction pendulum base has the advantages of smaller total projection area, lighter compound pendulum form structure and better realization of large displacement performance.

However, in an earthquake, there is often an upward pulling force, especially on a suspension lock bridge, a diagonal cable bridge and a multi-story building, displacement and upward pulling may be generated at the same time, and a conventional friction pendulum support cannot meet the working condition, so that the safety of the bridge and the building may be compromised.

Further, the stand unit 200 is used for a stand portion which is a friction pendulum stand, for a limit connection of the steel lining ball plate 101, and connection installation with a building or a bridge, as compared with embodiment 3. Generally, the upper support 201 and the lower support 202 are independent, and the two supports are generally arranged in the same way, but of course, different supports can be used, but the principle of friction pendulum operation is still the same, and in this embodiment, the supports with the same structural design are taken as an example for illustration.

Specifically, the structure of the lower support 202 is illustrated as a cylinder, and the periphery of the lower support is welded with a connecting lug plate E for connecting a sleeve and corresponding opening holes, so that the lower support can be installed and fixed through the connecting lug plate E and the corresponding opening holes on the side walls of the periphery; the lower end is a plane, the upper end surface is inwards sunken to form a spherical concave surface 202a, and the inwards concave spherical surface 201a can be processed by coating stainless steel plates or electroplating hard chromium so as to improve rigidity and wear resistance.

The second slide plate ring 203b and the second steel ring 303c are in contact with each other to form a second plane revolute pair P2; the side wall of one end of the pressure-bearing sliding plate 102 far away from the steel lining ball plate 101 is in sliding contact with the spherical concave surface 202a, so that a spherical sliding pair Q is formed.

The steel ball-lined plates 101 are symmetrically disposed on both sides, and thus, the upper and lower ends of the steel ball-lined plates 101 are identical to the components disposed between the upper and lower supports 201 and 202.

The rest of the structure is the same as that of embodiment 3.

The composite friction pendulum support is shown in the drawings 1-9 in combination with the specification in a predetermined position for installation to a building or bridge. When a building or a bridge vibrates, the upper support 201 and the lower support 202 displace with each other, and a spherical sliding pair Q exists between the pressure-bearing sliding plate 102 and the spherical concave surface 202a, so that sliding with a deflection direction can be coped with, and the first plane revolute pair P1 is easy to rotate on a horizontal plane; while the compression ring 301a is connected to the steel lining ball plate 101, when the steel lining ball plate 101 moves, the compression ring 301a pushes the pull ring 302a to move together in the through cavity 303 a-1; because the two parallel edges P of the pull ring 302a are located in the placing table 303a-2, when the steel lining ball plate 101 is combined with vibration of a single-side structure during displacement, eccentric force can be generated at the moment, the outer end of the pull plate 303a is circular, and the revolute pair can adapt to the eccentric force to rotate, namely, the second plane revolute pair P2 can rotate. After rotation, the guide sliding pair D forms a guide gradually rotating in the direction of the force, and the steel bushing ball plate 101 also moves in the direction of the guide gradually toward the force.

Because of the rotation of the first plane revolute pair P1 on the steel lined ball plate 101, the rotation of the upper end of the upper support 201 and the movement of the lower end thereof do not affect the movement of the lower support 202. When earthquake acting force acts on the upper end face of the steel lining plate 3, the motion of the steel lining plate 3 can drive the lower end face of the steel lining plate to do the motion, and the motion and the displacement can be coordinated with each other, so that the characteristics of a conventional compound pendulum structure support are met.

When an upward pulling force occurs, the snap ring 203a fixed to the upper holder 201 transmits the upward pulling force to the pulling plate 303a, and the pulling plate 303a is restrained in the holder. The pulling plate 303a transmits force to the place where the pulling ring 302a is buckled with the pulling ring 302a through the limit arc groove 303a-3 at the guiding position, the pulling ring 302a and the pressing ring 301a are mutually tensioned to transmit the force to the steel lining ball plate 101, and the lower support 202 is of the same structure, so that the force transmission is realized, the upward displacement of the support is limited, and the pulling-up force is resisted.

The friction pendulum support is matched with the structure, namely, the guide of the guide sliding pair D and the relative independent rotation of the first plane revolute pair P1 and the second plane revolute pair P2 are combined with the tensile function of each part, so that the friction pendulum support can realize the effect of resisting the pulling-up force when any displacement combination is designed.

It should be noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present utility model may be modified or substituted without departing from the spirit and scope of the technical solution of the present utility model, which is intended to be covered in the scope of the claims of the present utility model.
