Lub laum me me loj yuav tsum phim lub nominal txoj kab uas hla ntawm lub expansion thauj tog rau nkoj. Piv txwv li, 10mm expansion bolt feem ntau xav tau 10mm carbide-tipped masonry laum me ntsis. Nco ntsoov xa mus rau cov chaw tsim khoom cov lus qhia kev teeb tsa, vim qee yam tshwj xeeb thauj tog rau nkoj yuav xav tau kev hloov pauv me ntsis. Kev siv lub laum me ntsis tuaj yeem ua rau lub qhov loj, yog li nws yog ib qho tseem ceeb los hloov cov khoom tsis tu ncua.

Puas yog yas expansion anchors haum rau kev siv cov qauv?

Tsis yog, yas expansion anchors tsis haum rau kev siv cov qauv. Lawv tau tsim los rau kev ua haujlwm lub teeb xws li dai duab, txhim kho cov thawv hluav taws xob, lossis kho cov teeb pom kev zoo hauv cov phab ntsa ntub dej lossis cov mos mos masonry. Rau txhua daim ntawv thov kev thauj khoom, cov thauj tog rau nkoj hlau (carbon steel lossis stainless hlau) nrog cov ntawv pov thawj cov ntawv pov thawj yuav tsum tau siv.

Vim li cas qhov kev tu lub qhov tseem ceeb ua ntej txhim kho bolts expansion?

Kev tu lub qhov yog qhov tseem ceeb vim tias cov plua plav thiab cov khib nyiab ua qhov cuam tshuam ntawm cov thauj tog rau nkoj thiab cov khoom hauv paus. Qhov no txo ​​cov kev sib txhuam thiab cov khoom siv sib cuam tshuam tsim nyog rau lub thauj tog rau nkoj kom ruaj ntseg. Hauv tshuaj anchors, plua plav tiv thaiv cov resin los ntawm kev sib txuas ncaj qha mus rau cov pob zeb, txo cov peev txheej load. Ib txwm siv cov cua compressed los yog lub tshuab nqus tsev los ntxuav lub qhov kom huv si ua ntej tso.
