Introduction
> PTFE skateboard rubber bearing
A rubber bearing can be made by sticking a layer of PTFE plate on the surface of the general plate rubber bearing. The seat is also called PTFE slide rubber bearing series). In addition to having all the functions of a series of rubber bearings, the low friction coefficient between the PTFE sliding plate (plate) and the stainless steel plate at the bottom of the beam makes the horizontal displacement of the superstructure not restricted by the shear deformation of the bearing itself, which can meet the requirements of some bridges. Large displacement requirements. _ /PTFE slide rubber bearing
In addition to the function of spherical crown rubber bearing, it is also particularly suitable for bridges with large displacement. _ / PTFE slide rubber bearing
Not only has advanced technology and excellent performance, but also has the characteristics of simple structure, low price, no need for maintenance, easy replacement, buffering and isolation, and low building height. It is very popular and widely used in the bridge industry. (

Installation technical requirements
The support should be accurately positioned according to the planned support center. The steel plate on the bottom of the beam and the PTFE slide rubber bearing
The upper and lower sides The two _ / PTFE slide rubber bearings that are all closely attached to the same beam end should be placed on the same plane to avoid the phenomenon of eccentric pressure, uneven support and single hollowing of the bridge bearing.
It is necessary to cover the support with a stainless steel plate (thickness) and an upper steel plate (thickness Apply a thick layer of epoxy resin on the upper surface of the upper steel plate to bond it to the bottom of the beam.
When installing in the pit of the support, it should be filled with non-evaporable silicone grease as a lubricant to reduce the friction coefficient. The stainless steel plate in contact with the PTFE plate surface is not allowed to have damaging roughening phenomena to avoid increasing the friction coefficient and damaging the PTFE plate. Except for the stainless steel plate and the upper surface of the upper steel plate, all other parts of the upper steel plate assembly are painted with anti-rust paint. The relative position of the support and the stainless steel plate depends on the temperature during installation.

Rubber The product is one of the flagship products of Hengshui Railway Construction Holding Group. Plate bridge bearings, basin bridge bearings and other rubber products have a market share in the same industry. Their products are used in the Beijing-Shijiazhuang high-speed railway viaduct. Market share The rate has gradually increased and the annual sales volume of this product has climbed from the original 100 million yuan to the current 100 million yuan.
