Description
About Enquiry When making an enquiry, please provide the
most important design criteria of the bearing if possible, we can
then identify the appropriate bearings and provide the best
quotation. About Quotation For a detailed quotation we need
the following information: 1. Maximum,
minimum, permanent and life load vertical superimposed load
2. Horizontal
force longitudinal and transverse direction on the bridge
3. Most
adverse load combination of maximum horizontal force and minimum
vertical superimposed load 4. Movement
of the bridge in longitudinal and transverse directions
5. Rotations
of the bridge in longitudinal and transverse directions
6. Concrete
strength 7. General
structural details (concrete or steel bridge, fixing details of the
bridge bearings, arrow and counter bearing size etc.) A more
detailed list with the necessary information is defined in the
European Standard EN ***7, part 1. About Placing of orders
In addition to the above documentation, the following information
is needed when an order is placed: 1. Layout
drawing of the structure 2. Pre-setting
values Bearing manufacture begins once the documents confirming the
pre-setting values have been approved and returned to us. Thanks to
an efficient order processing system and modern manufacturing
methods, we can guarantee very short delivery times.

DESIGN
HORIZONTAL LOAD:
For free direction of fixed
bearing,
For longitude movement bearing,
For transverse movement bearing,
The design horizontal load of non-movement direction
is:
*5% of design vertical load: for areas where earthquake dynamic
peak acceleration: Ag=0.1g
*0% of design vertical load: for areas where earthquake dynamic
peak acceleration: 0.1g，less than the Ag of 0.*5g
*0% of design vertical load: for areas where earthquake dynamic
peak acceleration: 0.*5g, less than the Ag of
0.2g
For free movement bearing
For longitude movement bearing
For transverse movement bearing
The design horizontal load of movement direction is 5% of the
design vertical load.
The design rotation
angle is 0.*2rad
The
design displacement of a bearing: Design longitude
direction displacement for free movement bearing (DX) and
transverse movement bearing (ZX):
In the part of simple beam:
***0 to ***0KN plus or minus
*0mm
***0 to ***0KN plus or minus
*0mm
***0 to ***0KN plus or minus *0mm
In the part of continuous beam: ***0 to ****0KN plus or minus
**0mm
The design
friction coefficient of bearing: Normal temperature:

The design
height adjustment range of bearing:Adjust the height
with polyurethane in bottom or add steel plate on to top of the
bearing. The adjustment range,no less than *0mm
Temperature
range:
