Izindaba Zemboni

Ngokombono wenani lamabhizinisi, ukuphuma kwe-2019 kwesakhiwo sonyaka saseChina esingaphezu kwezigidi ezingamashumi ayisigidi, ama-100-500,000 amathani amabhizinisi angu-39, amabhizinisi aphansi naphakathi kwamabhizinisi aphakathi nendawo aphakathi nendawo.

Iplate ethwala phansi, eyaziwa nangokuthi yipuleti elinensimbi, ipuleti yensimbi yokwakha, isebenzisa i-grapezoged by roll tsress fress ebandayo yokugoba, i-tross-endime, i-trapezoidal noma i-trapezoidal noma i-trapezoidal noma i-thropezoidal noma ifomu lezinhloso ezingapheli, kodwa futhi lingakhethwa ezinye izinhloso.

Emlandweni wokwakhiwa komuntu, izinto zemvelo ezinjengomhlaba, amatshe nezinkuni zaqala ukusetshenziswa ngabantu njengezinto zokwakha. Ngokuthuthuka kwesayensi nobuchwepheshe emphakathini wesintu, i-iron nensimbi kwakhiqizwa ngezinga elikhulu, kuletha impahla eqinile, yokusebenza okuphezulu ekwakheni, okwenza kube nokwenzeka ukwakha izakhiwo ezinde neziphephile.

Ifreyimu eqoqiwe yensimbi ehlanganisiwe ye-Truss sakhiwo sohlelo ihlanganiswa amakholomu wefreyimu, ama-transver wendiza ama-trusses kanye nama-floor slabs. Amakholomu ahlelwe engxenyeni yendlu ngaphandle kwamakholomu enkampani, ukuphakama kwama-trusses kuyafana nokuphakama kwesakhiwo sendlu, kanye nobude obuphakeme kusekelwa amakholomu aphansi, ama-trusses ahlelwe kumalungiselelo aphansi angenamikhawulo ezansi ezinyaweni eziphakeme nezingaphansi.

Njengendlela entsha yokwakha ethuthukisiwe, ukwakhiwa komhlangano wesakhiwo sensimbi sekuthole ukunakwa okwengeziwe emakethe yaseShayina eminyakeni yamuva nje, futhi izinzuzo zayo kanye nokuba nokwenzeka kwayo kuxoxwe ngakho kabanzi.

Ukuze kube lula ukutholwa kokushisela nokushisela, indawo yokuhlukaniswa kwekholomu yensimbi ngokuvamile isendaweni ephakeme ecishe ibe ngu-1.2m phezulu, incazelo yepuleti elihlangene lekholomu yensimbi yensimbi efanayo ingcono kakhulu ukusebenzisa uhlobo, kufika kokubili, ukuze kube lula ukusetshenziswa kabusha izinto zokwakha.
