Dab tsi yuav tsum tau them nyiaj mloog mus rau hauv kev tsim kho ntawm Expansion Bolts?

Covexpansion ntsia liaj qhov roojyog ib tug tshwj xeeb threaded connector siv los kho cov pa duct txhawb nqa, hanger thiab bracket rau ntawm phab ntsa, pem teb thiab kem. Thaum siv, nws yog ib qho tsim nyog yuav tsum tau siv qhov cuam tshuam hluav taws xob laum (rauj) txhawm rau txhawm rau qhov sib xws ntawm qhov loj me ntawm lub cev ruaj khov, thiab tom qab ntawd nruab cov bolts thiab cov raj txuas rau hauv lub qhov. Tighten cov txiv ntseej kom cov bolts, cov raj nthuav dav, cov khoom sib txuas thiab lub cev ruaj khov nthuav dav mus rau tag nrho. Raws li cov lus hais mus, kev nyab xeeb zoo tsis muaj teeb meem me. Tshwj xeeb tshaj yog nyob rau hauv kev tsim kho cov txheej txheem ntawm expansion bolts, yuav tsum muaj ntau yam ceev faj. Cia wb mus saib lawv ua ke:

1. Qhov tob qhov drilling: cov ntaub ntawv tseem ceeb piav qhia txog qhov ntev ntawm cov yeeb nkab nthuav dav, tab sis nws pom tias qhov tob no yuav tsis txaus thaum lub sijhawm tsim kho tshwj xeeb, uas yuav cuam tshuam rau cov seem ntawm cov khib nyiab hauv lub qhov, yog li nws yog zoo dua yog hais txog 5 hli tob tshaj qhov ntev ntawm cov yeeb nkab expansion. Tsis tas li ntawd, rau dav dav M6 expansion bolts, lub qhov taub yog Φ 10.

2. Tau kawg, qhov nyuaj duaexpansion ntsia liaj qhov roojyog, qhov zoo dua hauv av. Qhov no kuj nyob ntawm qhov kev ntxhov siab ntawm cov khoom yuav raug kho. Lub zog kev ntxhov siab ntsia hauv pob zeb (C13-15) yog tsib zaug hauv cib.

3. A M6/8/10/12 expansion bolt raug ntsia rau hauv cov pob zeb muaj kev ntxhov siab ntau dua li ntawm 120/170/320/510 kg raws li qhov zoo tagnrho.
