Usekelo lwensimbi olulungisekayo lwezesekeli zesikafula

Kuyisikulufu esiyindilinga sensimbi esiphakathi kohlaka lwamathambo ensimbi, okuhlanganisa induku yokubopha, ukusekelwa okuvundlile kwechord engenhla, ukwesekwa okuvundlile kwechord ephansi, induku yesiphambano ethambekele nokunye. Impahla eyinhloko ngokuvamile i-Q235 wire rod, enobubanzi obungu-φ 12, φ 14 ivame kakhulu.

I-brace iyindawo yokusekela engaphandle kwendiza ye-purlin, ngakho ukushuba kwe-brace kuwumthwalo ovundlile othwalwa i-purlin. Isakhiwo sezikebhe zokuqondisa izinyawo ezikanyekanye kufanele sicabangele umthelela womthwalo womoya, sibale ingxenye yebrace ngokuya ngengcindezi yangempela, futhi sihlangabezane nezidingo zesakhiwo.

Izinsimbi ngokuvamile zihlanganisa lezi zinhlobo ezingu-12 zezingxenye ezilandelayo:

Ibholidi: Uhlobo lwesixhumi esihlanganisa ikhanda nesikulufu (isilinda esinentambo yangaphandle). Idinga ukufaniswa ne-nati ukubopha nokuxhuma izingxenye ezimbili ngokusebenzisa izimbobo. Lolu hlobo lokuxhuma lubizwa ngokuthi uxhumano lwe-bolt. Uma i-nati ikhishwe ku-bolt, izingxenye ezimbili zingahlukaniswa, ngakho-ke uxhumano lwe-bolt luwuxhumano olutholakalayo.

I-Stud: Alikho ikhanda, kuphela uhlobo lwesibambiso esinezintambo emikhawulweni yomibili. Lapho uxhuma, umkhawulo owodwa kufanele uboshwe engxenyeni enembobo yangaphakathi enentambo, omunye umkhawulo kufanele udlule engxenyeni ngembobo, bese i-nut iboshwe, ngisho noma izingxenye ezimbili zixhunywe ngokuqinile zizonke. Lolu hlobo lokuxhuma lubizwa ngokuthi i-stud connection, okubuye kube uxhumano olulahlekayo. Isetshenziswa ikakhulukazi lapho enye yezingxenye ezixhunyiwe inobukhulu obukhulu, idinga isakhiwo esihlangene, noma ayifanele ukuxhuma kwe-bolt ngenxa yokuhlakazeka okuvamile.
