Grid nodes damping rubber bearing, composed of skeleton rubber and metal sulfide. It is generally divided into three categories: first, it is the ordinary rubber bearing; Second, the axial damping rubber is

A; Third, the rubber bearing is tension and compression.

Ordinary rubber bearing, often used for resistance to dial the need of nodes, the action of external force it has vertical load and vertical Angle, the function of the shear resistance level. General directly

Using common bridge rubber bearing, or separately by production enterprises, according to the needs of engineering design.

In terms of applicability, the rubber bearing has simple structure, the assembly height is low, the characteristics of easy to install, and low cost, short production cycle, supply timely, so on

Composite force under the condition of not very big, is generally preferred.

Rubber nonlinear elastic polymer material, in an airtight case, almost is incompressible, only if the deformation is small, can only be approximately as a linear structure, its

Elastic modulus and the hardness and the shape of the bearing is closely associated. Only reasonable design, has the good function. Rubber bearing its design parameters, design requirements, calculation methods and processing technology is in accordance with the GB20688.4-2007 "rubber bearing and the fourth part: the ordinary rubber bearing standard strictly enforced.

Rack rubber bearing performance to choose:

Network frame construction node damping rubber bearing, according to its material and suitable temperature is divided into normal temperature type and hardy type two kinds. At room temperature using chloroprene rubber (CR), suitable for 25 ℃ -

60 ℃; Hardy type using natural rubber (NR), suitable for - 40 ℃ to 60 ℃ climate area, choose rubber bearing, node bottom slope is greater than 1%, the bearing

Should coincide with the node counterforce maximum bearing capacity, the tolerance should be within plus or minus 1%. Axial damping rubber bearing rack

Axial damping rubber bearing rack:

Axial damping rubber bearing structure (right), it is

In order to satisfy the node and vertical load is not higher than 4000 kn

The design. The support by the rubber piece and stiffening steel plate after

Heating, vulcanizing, considerable vertical stiffness,

Able to support upper component to the load. The stress situation

Through bearing local deformation under the condition of energy consumption reduction

Earthquake action. Support through the fixed bolt hole, by bolts

And components are fixed up and down. This bearing has certain vertical transfer

The Angle of function.
