Railway Bridge Expansion Device

　　The TSSF series expansion devices are mainly designed for medium and small span passenger dedicated railway bridges. Since the expansion devices set at the ends of medium and small span railway bridges do not directly bear the load of the wheels, these devices primarily focus on adapting to the expansion of the bridge and waterproof performance in such usage environments.

　　According to the different steel materials selected for the profile steel, this series of expansion devices can be divided into weather-resistant steel expansion devices and aluminum alloy expansion devices.

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.
