Bridge rubber bearing
|Thin plate rubber bearing, a kind of bridge bearing products, is composed by layers of natural
rubber and steel inlaid, glue, sulfide . This type of rubber bearing has enough vertical stiffness to
withstand vertical load, and the pressure of the upper structure can be reliably transmitted to pier;
Good flexibility to adapt to the rotation of beam end; Have larger shear deformation to meet the
horizontal displacement of the upper structure.
Classification of bridge rubber bearing according to the shape
|Rectangular plate, round, spherical cap circular plate and circular plate slope shape, such as
several kinds of products.
|1.Rectangular bridge rubber bearing (round)
(1) performance: this product by multi-layer rubber sheet and sheet steel inlaid, adhesive in a
certain pressure, a certain temperature and certain time sulfide suppression. Enough vertical
stiffness to pressure on the vertical load, the reaction force of the upper beam slab structure can
be reliably transmitted to pier, good elasticity, to adapt to the rotation of beam end; Have larger
shear deformation in order to meet the upper horizontal displacement of the beam body structure.
(2) features: this product is in the bridge construction, water and electricity engineering, building
aseismic facilities has been widely used, and the original compared with steel support, has simple
structure, convenient installation; Save, steel prices are low; Advantages of easy maintenance,
easy to replace, and low building height, the product is good for bridge design and reduce cost;
Has good vibration isolation effect, can reduce the seismic forces and the live load effect on the
impact of the building.
|2.PTFE sliding bridge rubber bearing
features: this product is on the ordinary plate rubber bearing bonding a 1.5 3 mm thick layer of
PTFE plate. Besides the ordinary plate vertical stiffness and elastic deformation of rubber bearing,
can withstand the vertical load and to adapt to the beam end rotation, because of PTFE and low
coefficient of friction between the beam bottom of stainless steel plate (mu 0.06 or less) can make
the horizontal displacement of the bridge superstructure is not restricted.
|3.Spherical cap round bridge bearing
features: this product is modified by circular plate bearing. At the top of the pedestal adopts pure
rubber ball surface, support adding a circle at the bottom of the R2.5 mm semi-circular ring. It
retains the advantages of isotropic circular plate bearing deformation, and can be overcome after
the installation is easy to produce the phenomenon such as bias, escapes, applicable to small
general bridge models, can also be applied to a variety of complex, large longitudinal slope of the
overpass and viaduct. According to the different slope can adjust the radius of spherical cap and
support the overall thickness.
Classification of bridge rubber bearing according to the different materials:
a.Neoprene: applicable temperature + 60 ºC -25 ºC
b.Natural rubber: applicable temperature + 60 ºC - 40 ºC
c.EPDM: applicable temperature + 60 ºC - 45 ºC
