Lasso shock-absorbing support

　　Product Performance

　　■ In normal usage, the support moves within the designed displacement range, and the cable does not serve as a limit; the cable damping support is the same as a conventional support.

　　■ In the event of minor and moderate earthquakes, the cable damping support resists seismic forces through shear pins, and it is generally not allowed to shear to avoid replacing the support after an earthquake; when the bridge structure encounters a rare earthquake, the shear pins of the cable damping support may shear, turning it into a damping support that dissipates energy through sliding friction and isolates the upper and lower structures, reducing the transmission of seismic forces; at the same time, the cable limits excessive dynamic displacement caused by the earthquake and provides sufficient restoring force to effectively limit displacement.

Lasso shock-absorbing support

In normal use, the support moves within the range of designed displacement, the cable does not play a limiting role, and the cable damping support is the same as the conventional support.

LRB highway bridge lead core seismic isolation rubber bearing

The highway bridge lead core seismic isolation rubber bearing is a standard bridge component product developed in accordance with national and industry-related standards, while also referencing European standards. This product is available in two types: rectangular and circular, suitable for various highway and municipal bridges in seismic zones of 8 degrees and below.

GKPZ(Ⅱ) Seismic Rubber Bearing

The GKPZ type bowl rubber support consists of an upper seat plate, a lower seat plate, a middle steel plate, a pressure-bearing rubber plate, a copper sealing ring, a rubber sealing ring, a polytetrafluoroethylene plate, an SF-1B composite plate, a stainless steel plate, a damping rubber ring, and a shock-absorbing plate. The supports are divided into 31 specifications based on vertical load capacity, ranging from 0.8MN to 60MN. Its structure is consistent with that of ordinary bowl rubber supports, with the addition of damping rubber rings and shock-absorbing plates, providing good seismic and shock-absorbing performance. The horizontal load capacity of the unidirectional movable support and fixed support is 20% of the vertical load capacity.
