I-joists inikezela ngeenzuzo kwiimveliso zemihlaba eziqhelekileyo ezinika ukongiwa komakhi kunye nokusebenza okungcono kwaye nya mezela ngaphezu kwexesha. Ukuze ufumane olu lwalondolozo, kuya kufuneka ukuba uqaphele xa ulawula i-Joists, ngoko kutheni sinamaphupha alandelayo kuwe.

I-Joists yokuPhatha kunye neZingcebiso zokuFakela

1. I-Joists kufuneka igcinwe kwaye ifakwe emacaleni kwaye imiswe xa ingasetyenziswa.
2. Musa ukugcina i- I-Joists esitratweni kwiindawo apho bangena khona ukudibanisa ngqo nomhlaba.
3. I-i-joists bundles kufuneka ivule xa ikulungele ukufakwa.
4. I-Joists ayizinzile okanye ikwazi ukulayisha ukulayisha ngaphandle kokuba ifakwe ngokufanelekileyo kwaye ixhaswe ngokupheleleyo.
5. I-joists kufuneka ikhonjiswe kwaye ibethelelwe phantsi njengoko ifakwe. Sebenzisa ii-joist ezilungileyo, ukuvala ii-panels, iiplanga zamabhodlela kunye ne-cross-bridging in joist.
6. I-joist yesikhusekiso sexeshana kufuneka ibe yi-1 x 4 intshi ubuncinci, ubuncinane ubunamamitha angama-8 ubude kwaye ingabi ngaphaya kwama-8 onyawo kwiziko.
7. I-joist yesikhusekiso esisigxina kufuneka ikhuseleke kunye ubuncinci besikhombiso sesibhozo ezi- 8 ezinamathele kwi-I-Joist nganye.
8. Xa usebenzisa i -tiletile I-Joists, bhonce amaflegi aphezulu kunye nezantsi, kwaye ukhumbule ukuba i-brace iphele ngamapaneli, ibhodi yomtya okanye ukugqithisa.

1. Faka ukutyhutyana kwexeshana okanye ukutyhutyana kwexesha elifutshane ukukhusela i-Joist ukusuka ekugqibeleni okanye ukukhangela . Emva kokuba isakhiwo sigqityiwe, umgangatho wesondlo unika inkxaso yenkxaso ye-lateral yee-top flanges ze-I-Joist.
2. Ukukhusela kuyadingeka kwenkxaso yangaphakathi xa i-Joists isetyenziselwa ngokuqhubekayo ngaphezu kwezinto zangaphakathi. Ezi bhloko mazibe zikhulu kunokuba u-I-Joist ubunzulu ukuze uqhube umthwalo opheleleyo. Khumbula ukubeka ezi bhloko kwii-i-joists eziphezulu nezisezantsi.

1. Qinisekisa kwiziko lewebhu le-I-Joist ngeebhloko zokhuni kumacala omabini o-I-joist nakwiindawo zokuthwala. Iibhloko zeenkuni ziyakuthintela umlenze ovela kwi-buckling .
2. Ungalokothi unqande, uqhube okanye unotshi I-Joists flanges . Ezi zicucu ezongezelelweyo ziya kunciphisa i-I-Joist load capacity ngokudala uxinzelelo olongezelelweyo kwaye i-I-Joist ingaphumeleka kamva.
3. I-intanethi yewebhu ye-I-Joist ifanele ifakwe. Ukuqhuba kufuneka kwenziwe kuphela ngokulandela iinkqubo ezithile njengoko kufundiswe ngumenzi we-I-Joist . Ezinye izimbobo ezinkulu njenge-1 ½ "ububanzi zinokunqunyulwa kwiwebhu ye-I-joist ngaphandle kokubonisana. Nangona kunjalo, abenzi be-I-Joist bafanele banike umgama ofunekayo phakathi kweemingxuma, phakathi kwama-flanges, phakathi kwembombo yokugqibela kunye nebala lokuthwala, kunye naphina naziphi na ezinye iindawo ezibalulekileyo ze-joist.
4. Ungaze uzame ukulungisa okanye ukufaka i-I-joist eyonakalisiweyo .
