Highly Strong Laminated Rubber Bearing To Taiwan - China

I

---The definition of rubber bearings

Rubber bearing is the supporting parts to support containers and equipment weight, and fixed on the position, but also bear the operation of vibration and seismic loads.

Rubber bearings are made of rubber and thin steel sheets and used for supporting the weight of the bridge.

II

--- The rectangular (circular) plate type rubber bearing

1 - Performance: This product is made of multilayer rubber sheets and thin steel inlaid.

It has enough vertical stiffness in vertical bearing load, and make the superstructure reaction reliably transfer to the pier, and has good elasticity to adapt to the rotation of the beam end, and has larger shear deformation to meet the horizontal displacement of the superstructure.

2 - Characteristic: This product in the bridge construction, hydropower engineering, earthquake resistant housing facilities has been widely used, compared with the original steel bearing, the advantage of the product is simple structure, convenient installation, steel saving, low price, easy maintenance, easy to change, good isolation effect, and it can reduce the live load and seismic forces to the building of the impact.

III

--- The characteristic about the PTEF plate rubber bearing.

This product is in ordinary laminated rubber bearings on the bonding of a thick layer of 1.5-3mm Teflon plate.

In addition to vertical stiffness and elastic deformation of ordinary laminated rubber bearing, it afford to vertical load and adapt to the rotation of the beam end, Because of tetrafluoroethylene and low coefficient of friction between the beam bottom of stainless steel plate (mu 0.08 or less), it can make the horizontal displacement of the bridge superstructure is not restricted.


IV

--- The installation details of the rubber bearing:

1 - When using this series of bearings, the bridge girder and bridge pier, the pier bearing part of the concrete grade shall not be less than 300 grade.

Special circumstances shall be subject to the consent of the design unit.

2 - Bearing and girder and piers, the pre buried bolt connection, when necessary it can also be with pre embedded steel plate welded connections, but when the bearing and girder and pier pre buried steel plate are welded to prevent overheating of bearing steel body, to avoid burning the silicone and PTFE plate.

3 - Bearing installation elevation should meet the design requirements, to ensure that the bearing surface is aclinic and smooth, the bearing surface four angles of elevation shall not be greater than 2mm.

4 - After bearing approach, check the packing list, including parts list, bearing products certificate, bearing installation and maintenance rules.

5 - Bearing installation should pay attention to the following matters:

a.

The bearing center line should be parallel to the main beam center line.

b.

The center line of the movable support on the upper support board and the lower support plate along the bridge direction should be coincident, the angle should not exceed 5 'rad.

c.

When the bearing is installed, the connecting plate of the upper supper plate and the lower support plate is not loosened to prevent the support from turning over a large angle, and the connecting plate is removed after the beam body is installed, so as to prevent the normal rotation of the beam body.

d.

Removal of upper and lower support plate, the SX and DX should be installed in a timely manner to install the rubber dust cover.

e.

Cast in situ concrete beams in the beam body into the whole and remove the connecting plate before the construction of prestressed concrete bridge.



f.

Before installing coaming, use cotton silk carefully wipe the surface of stainless steel sliding, to prevent dust intrusion PTFE plate surface.
