QZ spherical support

　　1. Product Introduction

　　The QZ series spherical bearings are more flexible in rotation compared to pot bearings, and can meet the needs of curved bridges, wide bridges, sloped bridges, and large-span bridges. The horizontal bearing capacity of fixed bearings in all directions and unidirectional bearings is 10% of the vertical bearing capacity.

　　The QZ series spherical bearings strictly comply with the national standard GB/T 17955-2009 "Technical Conditions for Spherical Bearings" of the People's Republic of China, and also refer to the draft of the structural bearing standard published by the European Committee for Standardization CEN/TC 167 in August 1993, specifically the seventh part "Spherical and Column PTFE Bearings" and the second part "Sliding Components", as well as the British standard BS 5400 "Steel Bridges, Concrete Bridges and Composite Bridges" Part 9 "Bridge Bearings".

　　2. Product Features

　　1) The spherical crown liner is made using a stainless steel cladding process, which provides high wear resistance and a low friction coefficient, enhancing the performance and service life of the bearings;

　　2) The vertical curve inner turning angle of the bearing is 0.02 rad, while it also adapts to any turning angle in flat curves, allowing for flexible rotation;

　　3) The wear-resistant plate is made of modified ultra-high molecular weight polyethylene, which meets the needs for high bearing capacity and also has good wear resistance and self-lubricating properties, extending the service life of the bearings and reducing maintenance costs;

　　4) The applicable environmental temperature range is (-40℃ to +60℃), allowing for wide geographical use;

　　The series QZ (1000-60000) KN spherical bearings produced by the company are applied in major domestic bridge projects such as the GuiJin Expressway, PingTian Expressway, Nanjing Xikou Bridge, LeXi Expressway, Yichang Three Gorges, JinNing Expressway, YiJin Expressway, BaoMao Expressway, Kaizhou Bridge, TongSai Expressway, ChengLe Expansion Project, JianGong Project, G310 Line, Sichuan-Tibet Railway, JinCheng ECP Project, CuiZhai Municipal, YangJiang Construction, and Chongqing No. 27 Rail Transit.

Other Products

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.
