Description

Structural improvement of sliding isolation support

The invention relates to a structural improvement of a sliding isolation support; in particular, to a sliding isolation support of a general building structure, which has a safety function that does not disintegrate when subjected to vertical vibration or tension.

As shown in Fig. 1, the conventional friction single pendulum isolation support (01) uses the sliding behavior of the slider (61) on the sliding surface (62) to achieve the effect of isolating the vibration, so that the slider (61) It can be completely attached to the sliding surface when sliding on the sliding surface (62), so the slider (61) and the base need to be inserted into the ball socket (04) with the ball head (03) as a connection to provide actuation. The rotation angle requirement of the slider.

The friction single pendulum isolation bearing (01) is inserted into the ball socket (04) with the ball head (03) as a connection. Although the bearing and angle change requirements can be provided in a simple structure, the vibration isolation support is easy because it has no anti-uplifting effect. At the same time, when the vertical and horizontal vibrations are applied, the whole mechanism is loose and easy to fall off. When assembling or installing. The components are easy to separate.

In order to make the sliding isolation support have the function of anti-uplifting and the integrity of the mechanism, the present invention is characterized in that after the ball head is covered by the combination of the ball socket and the ball socket cover, the ball socket or the ball head is connected with the slider, and the structure is When a vertical vibration is generated between the object and the foundation, or when a tensile force is generated between the structure and the foundation, it is ensured that the component of the sliding isolation support does not disintegrate and the structure sinks and collapses.

In the sliding isolation support (60) shown in Fig. 2, or Fig. 3, or Fig. 4, the sliding isolation support (60) is composed of a slider (61), a sliding surface (62), and a ball socket ( 11), the ball head (13), and the ball and socket cover (12), the ball seat (11) is provided with a spherical groove matching the size of the ball head (13), and the ball is embedded in the spherical groove The head (13), the ball head (13) is a ball structure, and has a connecting end, and the ball socket cover (12) is provided with a spherical groove matching the size of the ball head (13), and is engaged with the ball socket (11). After the ball head (13) is covered, the center of the ball socket cover (12) is provided with a circular hole position to expose the joint end and part of the spherical surface of the ball head (13), so the ball head (13) can be made limited. The large angle is free to rotate, and the ball socket (11) or the ball head (13) can be coupled with the slider (61), when a vertical vibration is generated between the structure and the foundation, or when a tension is generated between the structure and the foundation. It can ensure that the components of the sliding isolation support do not disintegrate and cause the structure to sink and collapse, so that the slider (61) can keep sliding on the sliding surface (62) to achieve the effect of isolating horizontal vibration.

A preferred application embodiment of the sliding isolation bearing (60) is shown in Figures 5 to 6, wherein Figure 5 shows the application of the sliding isolation bearing (60) of the general building structure (70); Figure 6 shows the application of the sliding isolation bearing (60) of the equipment machine or display cabinet (80).
