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.

The highway plate rubber bearing uses a vulcanized combination of an intermediate steel plate and rubber, fully utilizing the energy absorption and dissipation properties of rubber. It has the advantages of high bearing capacity, significant shock absorption and isolation effects, and is easy to maintain and replace. It provides significant economic benefits while meeting the corner requirements of bridges. The application of plate rubber bearings has promoted the advancement of bridge technology in our country and has now become one of the main types of bearings for medium and small span highways in China.

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.

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.

The QZ series spherical bearings strictly adhere to the national standard GB/T 17955-2019 "Bridge Spherical Bearings", while also referencing the European standard "Structural Bearings" Part 7 "Spherical and Cylindrical PTFE Bearings" (EN 1337-7) and Part 2 "Sliding Elements" (EN 1337-2), as well as the British standard BS 5400 "Steel Bridges, Concrete Bridges and Composite Bridges" Part 9 "Bridge Bearings". They feature flexible rotation and large angles, making them particularly suitable for wide bridges, curved bridges, ramp bridges, skew bridges, and large-span bridges.

JT/T391-2019 "Highway Bridge Pot Bearings", GPZ (2019) series pot bearings are the supporting drawings for this standard.
