LRB (Lead Roj Hmab Bearing) yog qhov siv dav tshaj plaws thiab tus nqi -kev sib xyaw ua ke ntawm seismic cais tawm hauv thaj chaw ntawm architecture thiab txuas hniav. Nws ua tiav cov txheej txheem seismic hloov kho los ntawm "rubber rho tawm + lead core zog dissipation".
I. Kev tsim kho yooj yim
- Ntau cov txheej txheem ntawm cov roj hmab thiab cov hlau txuas ntxiv yog alternately stacked thiab vulcanized
- Lub siab -purity lead core yog embedded nyob rau hauv nruab nrab los muab damping thiab zog dissipation
- Kev sib txuas cov phaj yog teem rau sab saum toj thiab hauv qab kom yooj yim anching nrog cov qauv
- Muaj ob hom qauv: voj voog thiab duab plaub
II. Mechanism ua haujlwm
- Vertical load-bearing: Lub phaj steel txwv cov roj hmab, muab kev ruaj khov ntsug
- Seismic isolation elongation lub sij hawm: Txoj kab rov tav hloov tau ncua sij hawm ntawm cov txheej txheem kev co ntawm 0.2-0.5 vib nas this mus rau 1.5-3.0 vib nas this, zam lub ntsiab seismic zaus band.
- Lead core yield zog dissipation: Thaum lub sij hawm muaj av qeeg, cov hlau lead hauv cov yas deformation, qhov sib npaug damping piv tau ncav cuag 15% -25%, absorbing seismic zog.
- Roj hmab tus kheej- rov pib dua: Tom qab av qeeg, cov roj hmab rov pib dua los ntawm elasticity
III. Core Performance
- Seismic teb txo: 60% -80%
- damping piv: 15% -25%
- Kev siv zog: Tsawg dua lossis sib npaug li 9 degrees
- Ua haujlwm kub: -25℃~ +60 degree
- Tsim kev pabcuam lub neej: Ntau dua lossis sib npaug rau 60 xyoo
