Laminated rubber bearing


I Product introduction of laminated rubber bearing

The rubber bearing is an ordinary rubber bearing products that made of multilayer thin steel plate and multilayer Rubber Sheet vulcanized and bonded together to form.




II Product division of laminated rubber bearing

It divides into the ordinary laminated rubber bearing and PTFE laminated rubber bearings. For ordinary bridge bearings is applicable to span less than 30m, bridge of small amount of displacement. Different plane shapes are applicable to different bridge span structure; orthogonal bridge with rectangular bearings; curved bridge, skew bridge and cylindrical bridge pier with round support.

The plate type rubber bearing is divided according to the shape:
 
Rectangular plate type rubber bearing Short side of the rectangular bearings and along the bridge direction is arranged in parallel in order to facilitate the beam end rotation. If you need the long side of the rectangular bearings and along the bridge direction is arranged in paralle, need to check. A. Performance: This product is developed by multilayer rubber sheets and thin steel inlaid to stick and press. There is enough vertical stiffness to be confined to the vertical load, The upper structure of the counter force can reliably transfer to the pier, have good elasticity to adapt to the rotation of the beam end, and larger shear deformation to meet the horizontal displacement of the superstructure.

B. Features: This product is widely used in bridge construction, water and electricity projects, housing seismic facilities. The device has the advantages of simple structure, convenient installation, saving steel, low price, convenient maintenance, easy replacement, etc.And the height of the building is low, which is beneficial to the bridge design and reduce the cost. It has good isolation effect and can reduce the impact of live load and earthquake force on buildings.
Circular plate type rubber bearing The circular bearing is isotropic.When installing no need to consider the direction. Only let the center of the support center and the design points to coincide. Installation of the horizontal block can prevent the centrifugal force of beam transverse moving.

Circular plate type rubber bearing has the following advantages:
(1) circular plate type rubber bearings can be flexible to absorb the deformation of the upper structure of the various directions;
(2) compared with the rectangular bearing, the bearing surface of the circular plate rubber bearing has no stress concentration;
(3) the circular plate type rubber bearing is easy to install and can not consider the direction;
(4) the circular plate type rubber bearing is low cost, convenient maintenance and maintenance.
Spherical circular plate type rubber bearing Spherical circular plate type rubber bearing is a kind of improved circular plate bearing, the rubber layer and steel plate arrangement are exactly the same as round plate type rubber bearing, and the support top surface is made into a spherical surface with pure rubber , maximum thickness of the spherical center of rubber glue 4-10mm.

Spherical circular plate type rubber bearing transmission force uniform, can significantly improve or avoid the bottom surface of the supporting seat generates the bias, void and other undesirable phenomena, especially for larger slope aspect (3% - 5%) interchanges and viaducts.
The slope plate rubber bearing The species can adapt to various bridge vertical slope, is a wedge shape of slope support based on the circular plate rubber bearing. Slope angle is manufactured according to the bridge vertical slope, greatly facilitate the design and construction of the bridge, and effectively remove the void phenomenon between the beam, support, pier, and it has the advantages of bridge vertical slope angle limit compared with spherical cap plate bearing.






III  PTFE slide plate rubber bearing

This product is in ordinary laminated rubber bearings on the bonding of a thick layer of 1.5-3mm Teflon plates and. In addition with ordinary laminated rubber bearing vertical stiffness and elastic deformation, under vertical load and adapt to the rotation of the beam end, because of tetrafluoroethylene and beam bottom stainless steel plate between the low friction friction coefficient (mu < 0.03), the horizontal displacement of the bridge superstructure is not restricted, is especially suitable for medium, small load, large displacement of bridge use. Rectangular, circular PTFE laminated rubber bearings used respectively with rectangular, circular ordinary laminated rubber bearing same.




IV Install

A: Installation Preparation

A.1 laminated rubber bearing installation should set the bearing pad stone, bearing pad stone plane size should be determined based on the local bearing calculation, pad stone length, width should be than the corresponding supporting seat size increase of at least about 50 mm, the height should be as 100mm, and should be considered for bearing replacement of the top beam when Jack mounting position.
A.2 bearing pad stone should be arranged in the steel mesh, steel bar diameter of 8mm, spacing should be 50mm x 50mm, bridge pier, the platform should have the vertical reinforcement to the bearing pad stone, bearing pad stone concrete strength should not be less than C30.
A.3 bearing pad stone surface should be smooth, clean, dry, no quicksand. Bearing pad stone top surface elevation accuracy required. In the flat slope, with a piece of the two ends of the beam bearing pad stone and with a pier, and bearing pad stone should in the same design elevation plane and the relative height should not exceed + 1.5 mm, with a bearing pad stone height difference should be less than 0.5 mm.

B: Bearing installation
B.1 Support approach should be bearing checks whether a manufacturer's trademark or permanent marker. Installation should be in accordance with the design drawings requirements in bearing pad stone and bearing were marked the position of the center line of the support, in order to ensure the bearing accurately in place.
B.2 bearings during the installation, should prevent seat appear bias or produced a large initial shear deformation. To complete the installation, you must ensure that the bearing and on and substructure close contact shall be void phenomenon. On has not formed the overall beam slab structure should be avoided by heavy vehicles.
B.3 bridge pier design should be considering bearing maintenance, need to be replaced. Under any circumstances, does not allow two or more than two bearings mounted in a along the longitudinal center line in the same support side by side; with a single beam (plate), lateral should not be set more than two bearings; bearings of different specifications should not be mounted side by side.
B.4 bearing after installation, should be comprehensive check bearing drain, bearing installation direction, position (with pre embedded steel plate contact, bearing centerline position) and bearing types is wrong, temporary fixed facilities are removed, PTFE sliding bearings are injected into the silicone oil is strictly prohibited use of lubrication oil instead of silicone oil) phenomenon, once found, should timely adjust and processing, guarantees bearing after installation of the normal work, and record the bearing is arranged after the deviations and exceptions.
B.5 The use of the average pressure volume Eb=2000MPa. stage bearing stress c=10MPa. bearing rubber elastomer. When the bearing is in contact with the concrete, the friction coefficient mu = 0.3; when in contact with the plate, the friction coefficient mu = 0.2; polytetrafluoroethylene plate and stainless steel plate contact (grease) friction coefficient mu f=0.06. When the temperature is lower than - 25 C, u F value is increased by 30%, if not add grease, u F value should be doubled.
B.6 The rectangular bearing is placed in a short side dimension along the bridge when stalled.
