Intshayelelo ekusebenziseni i-rebar

I-Rebar: “Amathambo nezihlunu” kwiiprojekthi zokwakha

I-Rebar, igama layo elipheleleyo elithi "i-hot-rolled ribbed steel bar", ibizwa ngokuba yi-ribbed steel bar esasazwe ngokulinganayo kubude bomphezulu wayo. Ezi ribb zinokwandisa unxibelelwano phakathi kwe-steel bar kunye ne-concrete, zivumela ezi zimbini ukuba zenze i-whole eqinileyo kwaye zimelane kunye namandla angaphandle. Njengezinto ezibalulekileyo ezibalulekileyo kwiiprojekthi zokwakha, i-rebar isetyenziswa kakhulu kwaye ibalulekile, kwaye ihamba phantse kuzo zonke iikhonkco ukusuka kwiziseko zophuhliso ukuya kwizakhiwo eziphakamileyo.

Intsimi yokwakha izindlu

Kwizakhiwo zikawonke-wonke nezezorhwebo, i-rebar ifana "ne-skeleton".

• Isiseko kunye neebhari: Isiseko, iikholamu ezithwala umthwalo, iibhari kunye nezinye izakhiwo eziphambili zendlu zifuna i-rebar ukuze zakhe umqolo wentsimbi uze emva koko zigalele ikhonkrithi. Umzekelo, iindonga ezichetyiweyo kunye neekholamu zesakhelo sezakhiwo zokuhlala eziphakamileyo kufuneka zixhomekeke kumandla aphezulu e-rebar ukuze zimelane nobunzima besakhiwo ngokwaso kunye nemithwalo yangaphandle ukuthintela ukuguquka kwesakhiwo okanye ukuwa.

• Umgangatho nodonga: I-mesh yentsimbi emgangathweni kunye neekholamu zesakhiwo eludongeni nazo zenziwe ngee-rebar. Ingasasaza uxinzelelo emgangathweni, inciphise ukwenzeka kweentanda, kwaye yomeleze ukuqina kunye nokumelana nokunyikima kodonga.

Ukwakhiwa kweziseko zophuhliso

• Ubunjineli bebhulorho: Nokuba yibhulorho yendlela enkulu, ibhulorho kaloliwe okanye ibhulorho edlulayo, i-rebar isetyenziswa kakhulu kwiindawo ezibalulekileyo ezifana neepiers zebhulorho, iidekhi zebhulorho, kunye neebhili ezithwala umthwalo. Xa ichaphazeleka ngokuphindaphindiweyo kukuqengqeleka kwezithuthi, ubunzima obungalinganiyo kunye nokusingqongileyo kwendalo (njengokutshintsha komoya kunye nobushushu), i-rebar inika ukumelana okwaneleyo kokuxinana kunye nokucinezelwa kweebhulorho, okuqinisekisa uzinzo kunye nobomi benkonzo yeebhulorho.

• Uthutho lweendlela noololiwe: Ekuqinisweni kwendlela kunye nolwakhiwo oluxhasayo lweendlela zendlela zangaphantsi komhlaba, i-rebar idla ngokusetyenziswa ukwenza izinto zekhonkrithi eziqinisiweyo ukuphucula amandla okuthwala eendlela kunye neendlela ukuze zikwazi ukumelana nemithwalo yezithuthi rhoqo.

• Iiprojekthi zokonga amanzi: Izibonelelo zokonga amanzi ezifana namadama okugcina amanzi, imijelo yokuphambukisa amanzi, kunye nee-culverts zichaphazeleka ixesha elide kwaye zixinzelelwe ngamanzi. Umqolo wentsimbi owenziwe nge-rebar unokuphucula kakhulu ukumelana nokuqhekeka kunye nokuqina kwezakhiwo zekhonkrithi, ukuqinisekisa ukusebenza ngokukhuselekileyo kweeprojekthi zokonga amanzi.

Ushishino kunye nobunjineli obukhethekileyo

I-Rebar ikwadlala indima ebalulekileyo kwizityalo zoshishino, kwiindawo zokugcina impahla, nakwiziseko zezixhobo ezinkulu. Umzekelo, isiseko sezixhobo zesityalo esinzima soomatshini kufuneka simelane nobunzima obukhulu bezixhobo kunye nokungcangcazela ngexesha lokusebenza. Ukudibanisa i-rebar kunye nekhonkrithi kunokubonelela ngamandla aqinileyo olwakhiwo ukuze kuthintelwe ukuhlaliswa kwesiseko okanye umonakalo. Ukongeza, kwezinye iiprojekthi ezikhethekileyo ezifana nezityalo zamandla enyukliya kunye neendawo zokufikelela kwizibuko, i-rebar kufuneka ihlangabezane neemfuno zamandla aphezulu kunye nokumelana nokugqwala ukuze ivumelane nemingeni yeendawo ezikhethekileyo.

Ngamafutshane, i-rebar, eneempawu zayo ezintle zoomatshini kunye nokusebenzisana okuhle nekhonkrithi, iye yaba "yithambo" lokuqinisekisa ukhuseleko lwesakhiwo kwiiprojekthi zokwakha zanamhlanje, ixhasa zonke iintlobo zezakhiwo ukusuka kwimizobo yoyilo ukuya kwinyani.
