Zithini Izinto Zentsimbi?
Iiprops zentsimbi (ezaziwa ngokuba ziiprops zentsimbi ezilungisekayo, iiprops zentsimbi ezithelekisiweyo, okanye iiprops zeshoring) ziinkqubo zenkxaso ezithe nkqo zexeshana ezisetyenziswa kakhulu ekwakheni, ekuhlaziyeni, nakwiizicelo zefomwork. Ziqulathe ityhubhu yangaphakathi kunye netyhubhu yangaphandle enendlela yokulungisa ephiniweyo, evumela utshintsho olukhawulezileyo lokuphakama ukuxhasa iislabs, imiqadi, iindonga, kunye nezinye izinto zesakhiwo ngexesha lomsebenzi wokulungisa okanye wokulungisa ikhonkrithi.
Ngokungafaniyo neepali ezinde ezizinzileyo, izixhobo zentsimbi zibonelela ngokulungelelaniswa okungenasiphelo kuluhlu lokusebenza - ngesiqhelo ukusuka kwi-1.5 m ukuya kwi-5.5 m nangaphezulu - nto leyo eyenza ukuba zibe yimfuneko kwiindawo zokwakha zanamhlanje.
Kutheni Izixhobo Zentsimbi Zibalulekile Ekwakhiweni
Izixhobo zentsimbi zibonelela ngezibonelelo ezintathu eziphambili:
-
Umthamo wokuthwala umthwalo – intsimbi yodidi oluphezulu (umz., i-Q235 okanye i-S355) inika imithwalo yokusebenza ekhuselekileyo ukusuka kwi-10 kN ukuya ngaphezulu kwe-30 kN ngepropu nganye.
-
Ubude obuhlengahlengiswayo – ukulungiswa ngokukhawuleza kwephini-ukutshixa okanye i-screw-collar konga ixesha lomsebenzi kwaye kuyahambelana nokuphakama okuhlukeneyo ukusuka kumgangatho ukuya kumgangatho.
-
Ukuqina – unyango olufanelekileyo lomphezulu (opeyintiweyo, ogqunywe ngomgubo, okanye ofakwe i-hot dip galvanised) lumelana nokugqwala kwaye lusetyenziswa kwakhona kwiiprojekthi ezininzi.
Iintlobo eziphambili zezixhobo zentsimbi
| uhlobo | Iimbonakalo | Eyona ilungiselelwe |
|---|---|---|
| Ipropu yentsimbi ephiniweyo eqhelekileyo | Ityhubhu yangaphakathi/yangaphandle enemingxuma ebhoboziweyo kunye nephini yokutshixa; ilula kwaye ingabizi kakhulu | Inkxaso yeslab kunye nomqadi ngokubanzi |
| Ipropu yekhola yesikrufu (enemisonto) | Ingalungiseka ngekhola enemisonto; ulawulo lokuphakama olucokisekileyo | Ukuchaneka okuphezulu kunye nemithwalo enzima |
| Ipropu enzima | Ububanzi betyhubhu enkulu (umz., 76 mm) kunye nobukhulu bodonga obukhulu | Iiprojekthi zoshishino, udonga oluphezulu |
| Ipropu yealuminiyam ekhaphukhaphu | Ayinakonakalisa, kulula ukuyiphatha | Umsebenzi wezindlu, iindawo ezixineneyo zokufikelela |
Iindlela Zonyango Lomphezulu – Yintoni Onokuyikhetha?
Ukugqitywa komphezulu kuchaphazela ngqo ubomi benkonzo kunye neendleko. Njengoko abathengi abaninzi bebuza:
-
Ipeyintiwe – ukhuseleko olusisiseko lokugqwala, ixabiso eliphantsi, elifanelekileyo ukusetyenziswa ngaphakathi okanye ixesha elifutshane.
-
Ipeyintiwe ngomgubo - isiphelo sayo sihlala ixesha elide, ayitshiphusi, ilungele ukubonakala ngaphandle okuphakathi.
-
Ifakwe i-galvanized kwangaphambili – i-zinc coating ifakwa ngaphambi kokuba kwenziwe ityhubhu; ilingana kodwa incinci kakhulu.
-
I-electro-galvanized – isiphelo esigudileyo nesikhanyayo; ukusebenza okuphakathi kokulwa nomhlwa.
-
I-Hot dip galvanized (HDG) – yeyona maleko ye-zinc etyebileyo, ilungele kakhulu iimeko ezingqwabalala kunye nokusetyenziswa kwakhona ixesha elide.
✅ Kwiiprojekthi zokuthumela ngaphandle okanye zangaphandle, i-hot dip galvanised yeyona ikhethwayo.
Indlela yokukhetha iProp yentsimbi efanelekileyo – Izinto ezi-5 eziphambili
Xa ukhetha izixhobo zentsimbi zeprojekthi, cinga ngoku:
-
Umthwalo ofunekayo wokusebenza – bala umthwalo olindelekileyo (ubukhulu beslab + umthwalo ophilayo) kwaye wongeze into yokhuseleko (ngesiqhelo izihlandlo ezi-2–3).
-
Ukuphakama okuphezulu nokuncinci – linganisa ukusuka emhlabeni ukuya kwi-soffit; khetha ipropu enokuphakama okuvaliweyo ≤ indawo ekhoyo kunye nokuphakama okwandisiweyo ≥ ubude obufunekayo.
-
Ububanzi betyhubhu kunye nobukhulu bodonga – indibaniselwano eqhelekileyo: 48×3.0 mm (umsebenzi olula), 60×3.0 mm (ophakathi), 76×3.5 mm (umsebenzi onzima).
-
Unyango lomphezulu – khetha ngokusekelwe kwiimeko zendawo yokusebenza (umswakama, ixesha lokuvezwa, imijikelo yokusetyenziswa kwakhona).
-
Ukuthobela imigangatho - khangela i-EN 1065 (umgangatho waseYurophu) okanye ezinye iziqinisekiso zasekuhlaleni zokuqinisekisa umgangatho.
