Kev siv ntawm Bolts
Bolts yog cov ntsiab lus fastening siv thoob plaws hauv txhua qhov kev lag luam los tsim kom tshem tau, thauj khoom -cov kabmob sib koom ua ke ntawm cov khoom. Lawv lub peev xwm los tsim kom muaj kev tswj hwm clamping quab yuam los ntawm kev nro ua rau lawv qhov tseem ceeb hauv kev siv xws li cov khoom siv rau cov khoom siv tseem ceeb.
1. Kev tsim kho thiab Civil Engineering
Cov qauv hlau txuasHigh - lub cev muaj zog bolts (ASTM A325, A490, EN 14399) yog cov khoom tseem ceeb rau steel ncej vaj tse, txuas hniav, thiab cov pej thuam. Cov kev sib txuas no yuav tsum tiv thaiv qhov nro, shear, thiab kev sib xyaw ua ke thaum tso cai rau kev sib dhos thiab kev tshuaj xyuas yav tom ntej. Kev tswj nruj (twist-tawm) bolts yog siv dav hauv kev tsim kho steel niaj hnub vim tias lawv cov splined xaus shear tawm ntawm qhov tseeb preload, kom ntseeg tau tias muaj zog clamping tsis tu ncua tsis muaj kev pov thawj torque wrench.
Pob zeb thiab Masonry AnchoringAnchor bolts (J-bolts, L-bolts, wedge anchors, sleeve anchors) ruaj ntseg cov kab ke, khoom siv, thiab facades rau cov pob zeb ua vaj tse. Expansion bolts tuav cov khoom hauv paus los ntawm kev siv tshuab deformation, muab rub- tawm kev tawm tsam hauv ob qho tib si tawg thiab tsis tawg. Cov ntawv thov no xav tau bolts nrog lub peev xwm thauj khoom siab thiab tsis kam mus rau dynamic thiab seismic rog.
InfrastructureCov kev tiv thaiv kev loj, cov qauv kos npe, cov ncej teeb pom kev zoo, thiab cov khoom siv hauv kev tsheb ciav hlau tso siab rau qhov hnyav - lub luag haujlwm bolts los tiv thaiv ib puag ncig, kev co, thiab kev cuam tshuam. Kub-dip galvanized lossis weathering steel bolts tau teev tseg rau kev pab cuam lub neej ntev hauv qhov chaw sab nraum zoov.
