Bridge Bearing
(II) Type Pot-type Rubber Bearing Installation Method
It is recommended to set supporting pads under the pot-type bearing. The specifications of the sleeve nut and the location of the holes require the surface of the supporting pad to be flat. During construction, when setting the elevation of the top surface of the support pad, attention should be paid to the thickness of the epoxy mortar cushion reserved under the support bottom plate. The padding stones outside the base plate of the support are used to form a slope to prevent water accumulation.
Before installing the support, you can unpack and check the components and packing list of the support. The support must not be disassembled at will before the support is installed.
The PTFE bearing is a polytetrafluoroethylene plate adhered to the surface of the ordinary plate rubber bearing to make a rubber bearing, also known as the PTFE sliding plate bearing (, series ). In addition to having all the functions of a series of rubber bearings, the low friction coefficient between the polytetrafluoroethylene plate (plate) and the stainless steel plate at the bottom of the beam makes the horizontal displacement of the upper structure not limited by the shear deformation of the bearing itself. It can meet the large displacement needs of some bridges. In addition to the function of a spherical crown rubber bearing, this plate rubber bearing is also particularly suitable for bridges with large displacements. PTFE plate rubber bearings not only have advanced technology and excellent performance, but also have the characteristics of simple structure, low price, no need for maintenance, easy replacement for buffering and isolation, and low building height. They are very popular in the bridge industry and are widely used.
> Rubber bearing performance and classification
, classification
① The two-way movable bearing has vertical rotation and longitudinal and transverse sliding properties, codenamed. ② The one-way movable bearing has the sliding performance of vertical rotation in one direction, codenamed. ③The fixed bearing only has vertical rotation performance, codenamed.
, Applicable temperature range of rubber bearing
Warm type bearing is suitable for ℃℃, cold type bearing is suitable for ℃℃, code name
The technical performance of the vertical angle of the seat is not less than. The axial bearing capacity is graded together, and the horizontal bearing capacity of the non-slip surface is vertical. Friction coefficient, normal temperature type, cold-resistant type
The series of spherical bearings are characterized by reliable force transmission and flexible rotation. They not only have the characteristics of large load-bearing capacity of basin-type rubber bearings, large seat movement, etc., but also can better It adapts to the needs of large turning angles and has the following advantages compared with ordinary pot-type bearings
The spherical rubber bearing transmits force through the spherical surface, and there will be no force necking phenomenon, and the reaction force acting on the concrete is relatively uniform
br/> The spherical bearing realizes the rotation process of the bearing through the sliding of the spherical PTFE plate. The rotating torque is small, and the rotating torque is only related to the spherical radius of the bearing and the friction coefficient of the PTFE plate. The size of the seat's rotation angle is irrelevant, and it is especially suitable for the requirements of large rotation angles. The design angle can reach br/>. The spherical bearing has consistent rotation performance in all directions. It is suitable for wide bridges and curved bridges
. This bearing product does not use rubber. Pressure-bearing, there is no impact of rubber aging on the rotation performance of the bearing, especially suitable for low-temperature areas.
