Product Description
LRB
Lead Core Rubber Bearings (LRB) consists of a laminated rubber and steel bearing with steel flange plates for mounting to the structure. Ninety percent of our isolators have an energy dissipating lead core. The rubber in the isolator acts as a spring. It is very soft laterally but very stiff vertically. The high vertical stiffness is achieved by having thin layers of rubber reinforced by steel shims. These two characteristics allow the isolator to move laterally with relatively low stiffness yet carry significant axial load due to their high vertical stiffness. The lead core provides damping by deforming plastically when the isolator moves laterally in an earthquake. The shims for isolators are cut to exacting tolerances by laser. The steel mounting plates are machined by computer-controlled milling machines that give high production throughput and accuracy. Molding each bearing takes 8 to 48 hours depending on the size of the bearing. The curing phase is continuously monitored to ensure that the rubber is uniformly cured throughout the bearing.
A Hole will be cut in the middle of the ordinary rubber bearing,and lead-core rubber bearing will be formed by pouring lead.this type of support has not only a higher damping ratio,but also a certain initial stiffness.so it can provide the building with seismic and wind resistance.
PRINCIPLE OF ISOLATION TECHNOLOGY
Seismic isolation technology refers to the installation of a seismic isolation layer composed of seismic isolation bearing and dampers on a certain floor of a building.to meet the expected seismic requirements,the technology can extend the natural vibration period of the entire structure system,increase damping,and reduce the seismic energy input to the superstructure.at present,the most widely used seismic isolation device is the vibration isolation rubber bearing.
Advantage of Isolation buildings
APPLICATIONS
LAIBIN Quality Lead-Core bearing/inflated rubber balloons/Lead core bearing
At present because the market competition is intense, customer demand, many rubber bearing manufacturer from the cost reduction, using poor quality rubber, this one can be seen from the appearance, good rubber, the surface is the deep, dark, press with finger can feel a little bit of flexibility, quality almost rubber, surface hair black, without burnish. Our company is processing the size of the rubber pad, various specifications for processing can be, if you have any special requirement need to confirm the drawing of the rubber pad, rubber mat, beautiful and easy, application range, are the best friends of friends engineering quality.
