Supply large quantities of rubber bearings in stock in Datong City

>Classification and effects of rubber bearings
>, Series rubber bearings
> The bearing is made of several layers of rubber sheets and thin steel plates that are vulcanized under pressure. It has sufficient vertical stiffness to meet vertical loads and good elasticity to adapt to the rotation of the beam end. It has large shear deformation to meet the horizontal displacement of the superstructure and has excellent anti-seismic effect, which can reduce the impact of dynamic loads on the superstructure and piers. It has simple structure, convenient installation, low price, simple maintenance and easy replacement.
>Series of rubber bearings
> This bearing is made of a thick layer of polytetrafluoroethylene plate glued on the series of bearings according to the plane dimensions of the bearing. In addition to having the function of a bearing , due to the low friction coefficient between the plate and the stainless steel plate at the bottom of the beam, the horizontal displacement of the superstructure is not constrained by the shear deformation of the support itself, reducing shear force. It can also be used to slide bulky objects, such as bridge connections. Beam pushing construction.
>Series of rubber bearings
> This bearing has horizontal shear isotropy and can effectively transmit multiple deformations of the superstructure. It has outstanding advantages in the application of curved and inclined bridges.
>Series of rubber bearings
> This bearing is made of a thick layer of polytetrafluoroethylene plate glued on the series bearing according to the surface dimensions of the bearing. In addition to having all the functions of a series of bearings, because it uses the low friction coefficient between the plate and the stainless steel plate at the bottom of the beam, the horizontal displacement of the superstructure is not restricted by the shear deformation of the bearing itself, which can meet the requirements of some bridges. Large displacement requirements.
>, series of rubber bearings
> In addition to the function of a general bearing, this bearing also has the function of adjusting the position of the stress base through the spherical surface rubber layer when a force effect is exerted on the beam end, and gradually The force spreads to the steel plate and rubber layer of the circular plate rubber bearing, making the bearing evenly stressed. It is especially suitable for inclined bridges such as skew bridges and overpasses.
>Series of rubber bearings
> This bearing is made of a layer of polytetrafluoroethylene plate bonded to the bottom surface of the spherical cap series bearings. In addition to the function of spherical crown bearing, it is especially suitable for bridges with large displacement.
>Factors affecting quality
> The gum of the rubber selected is the main factor affecting the quality of plate rubber bearings
At present, due to fierce competition in the market and fierce price reduction by customers, many _ / Rubber bearings
manufacturers reduce costs from this point and choose inferior rubber. This can be seen from the appearance. Good rubber has a shiny and black appearance. You can feel a little elasticity when you press it with your fingers. , the rubber of poor quality has a black appearance and no luster. However, the real quality of colloid needs to be tested and judged from the aspects of compressive elastic modulus and shear elastic modulus.
> Internal steel plate The steel plate is the guarantee of the bearing capacity of the plate rubber bearing
, so the thickness of the steel plate must meet the standard, the raw material must be the finished plate, and no bending plate, etc., in the processing Be sure to remove rust, sandblast, and then ensure the bonding between the rubber and the steel plate.
>, Production process of plate rubber bearings
Automatic production has not yet been completely completed. The process before vulcanization is basically manual operation. The quality of unloading, cutting, lamination and other processes depends on the workers. proficiency is closely related. The vulcanization time and temperature control on the vulcanizer are also very important. Different standards of rubber bearings have different vulcanization times. If the corresponding vulcanization time cannot be reached, inclusions will occur. The glue is not fully vulcanized, which affects product quality.

According to the annual dangerous bridge maintenance plan of the Provincial Highway Bureau, the maintenance department of Jiangyin Department On March 1, bridge maintenance was carried out on the Taocheng Bridge on the provincial highway in the jurisdiction. The Taocheng Bridge was built in 2001 and is an important node connecting Jiangyin and Zhangjiagang in the eastern section of the provincial highway. However, after nearly ten years of load-bearing, a basin-type rubber bearing on the east side of the bridge has become diseased. In order to ensure the safety of bridge traffic, the maintenance department decided to replace the pot-type rubber bearing of Taocheng Bridge after preliminary on-site investigation and discussion. This is the first time that the maintenance department has come into contact with the special maintenance of bridge pot rubber bearing replacement. The whole department attaches great importance to it, and specially organizes on-site observation and learning for the heads of each work area and technicians, and strives to improve the technical level of employees. After five hours of continuous work, the bridge's basin-type rubber bearings were successfully replaced.
