Description

Technical Field

[0001] The invention relates to the technical field of building earthquake-proof devices, and in particular to an earthquake-proof support for a public building foundation and an installation process. Background Art

[0002] The existing document with announcement number CN112227551A discloses an anti-seismic bearing for buildings, which includes a support seat, a bearing plate and a driving assembly. A bearing plate is horizontally arranged above the support seat, and a mounting groove is horizontally opened inside the support seat. Hollow plug rods are vertically rotatably penetrated on both sides of the bottom end surface of the mounting groove, and rubber columns are movably penetrated inside the two groups of plug rods. The top of the rubber column passes through the top wall of the mounting groove and is fixedly connected to the bearing plate. A second spring is vertically sleeved on the outside of the rubber column, and the two ends of the second spring are respectively abutted against the bearing plate and the bottom wall inside the plug rod; a driving assembly is arranged inside the mounting groove between the two groups of plug rods, and the driving assembly includes a first bevel gear, a second bevel gear, a rotating rod, a third bevel gear and a servo motor.

[0003] The seismic bearing mechanism designed in the above scheme is provided with a corresponding transmission mechanism. When performing seismic work or working for a long time, the transmission components in the seismic bearing mechanism are prone to aging or even damage, which has a great impact on its seismic performance. The existing building foundation seismic bearings generally use laminated rubber bearings, which are structural members with small horizontal stiffness and large vertical stiffness. They can withstand large horizontal deformations and can be used as part of the load-bearing system.

[0004] In the prior art, the seismic bearing device is mainly composed of a rubber seismic damping member, an upper support seat plate, a lower support seat plate and corresponding embedded connecting members. The rubber seismic damping member is provided with a lead core and multiple layers of rubber and steel plates. The rubber and steel plates are arranged in a staggered manner, and the outer layer thereof is wrapped with a rubber protective layer. During installation and construction, on the one hand, the seismic bearing device is generally brought to the construction site, and then the upper support seat plate, the lower support seat plate and the embedded connecting plate are connected, and the embedded connecting plate is provided with corresponding embedded ribs. On-site installation is generally fixed by bolts or welding, which is not only troublesome to operate, but also causes misalignment of the support seat plate and the embedded connecting plate, which not only affects the construction quality, but also has a negative effect on its seismic performance.
