Ityala leBenchmark | Ii-H-Beams, ii-Angle Steels kunye neePlates zeNtsimbi zithunyelwe e-El Salvador kwiProjekthi yoLwakhiwo lukaRhulumente

Umthengi wethu yinkampani yobunjineli bokwakha eyaziwayo e-El Salvador, enikwe umsebenzi wokwakha isakhiwo seofisi sikarhulumente kamasipala esibalulekileyo eSan Salvador—isixeko esilikomkhulu. Njengeprojekthi karhulumente ebalulekileyo, ifuna ukuthotyelwa ngokungqongqo kwemithetho yokwakha yasekuhlaleni kunye nemigangatho yomgangatho wamazwe ngamazwe, kunye neemfuno eziphambili eziquka ukhuseleko oluphezulu lwesakhiwo, ukuqina, kunye nokuzivumelanisa neemeko zommandla wenyikima wase-El Salvador. Le projekthi ifune uluhlu olupheleleyo lweeprofayili zentsimbi ukwenza isakhelo esithwala umthwalo wesakhiwo, ukuxhasa ulwakhiwo, kunye neeslabhu zomgangatho, okwenza umgangatho kunye nokusebenza kwezixhobo zentsimbi kubaluleke kakhulu kwimpumelelo yeprojekthi.

Isisombululo seMveliso: Iiprofayili zeNsimbi ezenzelwe wena zeZakhiwo zeZakhiwo zikaRhulumente

Emva konxibelelwano olunzulu lobuchwephesha, ukuphononongwa kwemizobo yoyilo lweprojekthi, kunye nohlalutyo lweemfuno ze-seismic kunye ne-load-bearing, sinikezele ngesisombululo esibanzi esinee-H-beams, ii-angle steels, kunye neepleyiti zentsimbi—zonke zenzelwe ukuhlangabezana nemigangatho eqinileyo yokwakha karhulumente. Iingenelo eziphambili zemveliso kunye nokwenza ngokwezifiso zezi zilandelayo:

- Iimitha ze-H(Ulwakhiwo oluPhambili lokuthwala umthwalo):Yamkelwe i-Q355B (elingana neI-ASTM A36) ii-H-beams zezinga, icandelo eliphambili elithwala umthwalo kwisakhelo sesakhiwo. Eli zinga linamandla amakhulu okuvelisa (ubuncinci be-355 MPa) kunye namandla okutsalwa (ubuncinci be-470 MPa), okwenza ukuba ikwazi ukumelana nobunzima besakhiwo, umthwalo wokuhlala, kunye namandla enyikima. Iinkcukacha ezenziwe ngokwezifiso (ubude: 200mm-600mm, ububanzi beflegi: 100mm-250mm, ubukhulu bewebhu: 6mm-14mm) zibonelelwe ukuze zihambelane neeleya ezahlukeneyo kunye namacandelo esakhiwo sesakhiwo sikarhulumente.

- Iintsimbi ze-Angle(Ukuqiniswa kwesakhiwo kunye nokuBekwa kweefreyimu):Iintsimbi ze-engile ze-Q235B (ezilingana ne-ASTM A283 Gr.C) ezibonelelweyo zokuxhasa ulwakhiwo, uqhagamshelo lwe-truss yophahla, kunye nolwakhiwo lodonga. Ngobuchule obugqwesileyo bokuguqa kunye nokusebenza ngokugoba, iintsimbi ze-engile zonyusa uzinzo olupheleleyo kunye nomthamo wokulwa nokushukuma kwesakhiwo. Ubungakanani obulungiselelwe wena (ubude bemilenze: 50mm-125mm, ubukhulu: 5mm-10mm) benzelwe ukulingana neemfuno zoqhagamshelo oluntsonkothileyo lwezakhiwo ezingathwali mthwalo zesakhiwo.

- Iipleyiti zentsimbi(IiSlabs zoMgangatho kunye nokuQinisekiswa kweZakhiwo):Kubonelelwe ngeepleyiti zentsimbi ze-ASTM A36 zokwenza iislab zomgangatho kunye neendawo ezibalulekileyo zokuqinisa ulwakhiwo. Ezi pleyiti zinobukhulu obufanayo (8mm-20mm) kunye nokuba tyaba okuphezulu, ukuqinisekisa ukuwelda okungenamthungo nge-H-beams kunye nokudluliselwa komthwalo okuthembekileyo. Ulawulo oluqinileyo lomgangatho womphezulu (akukho mifantu, ukufakwa, okanye iziphene) lwenziwe ukuhlangabezana nemigangatho ephezulu yokwakha karhulumente.

- Ukuthobela Umgangatho:Zonke iiprofayili zentsimbi ziye zavavanywa ngononophelo lomgangatho, kuquka uhlalutyo lokwakheka kweekhemikhali, uvavanyo lwepropathi yoomatshini, kunye nokuhlolwa kokuchaneka kobukhulu. Ziyahambelana ngokupheleleyo nemigangatho yamazwe ngamazwe ye-ASTM kunye neekhowudi zokwakha zasekuhlaleni zase-El Salvador, kunye nezatifikethi ezipheleleyo zomgangatho ezibonelelweyo ukuze kube lula ukwamkelwa kweprojekthi ngabasemagunyeni bakarhulumente.

Imeko yesicelo kunye nokuphunyezwa kwaso

Iiprofayili zethu zentsimbi zazisetyenziswa kakhulu kwisakhiwo esiphambili sesakhiwo seofisi sikarhulumente:

1) Imiqadi ye-Hbakha iintsika eziphambili zesakhelo kunye neebhanti, bexhasa ubunzima besakhiwo sonke kwaye bexhathisa amandla asecaleni (ukunyikima, umoya);

2) Iintsimbi ze-engile zisetyenziselwe ukuhlanganisa ifreyimu kunye ne-roof truss, nto leyo ephucula ukuqina kwesakhiwo;

3) Iipleyiti zentsimbi zicutshungulwe zaba zii-slabs zomgangatho ezidityanisiweyo kwaye zisetyenziselwa ukuqinisa amalungu e-beam-column, nto leyo ephucula uzinzo lonxibelelwano.

Ukuqinisekisa inkqubela phambili ethe tye yale projekthi iphambili karhulumente, iqela lethu linike inkxaso yobungcali epheleleyo:

1) Ukusebenzisana ngokusondeleyo neqela lobunjineli lomthengi ukuphucula iinkcukacha zemveliso, ukuqinisekisa ukuhambelana ngokugqibeleleyo noyilo lwesakhiwo;

2) Ukulungiselela uthutho olusebenzayo lwaselwandle kunye neenkqubo zokucoca irhafu ezilungelelanisiweyo, ukuhambisa zonke iiprofayili zentsimbi kwindawo yokwakha eSan Salvador ngaphambi kwexesha elicwangcisiweyo;

3) Kuthunyelwe iingcali zobugcisa kwindawo ukuze zinike isikhokelo malunga nokufakelwa kwentsimbi, ulawulo lomgangatho wokuwelda, kunye nokulungelelaniswa kwesakhiwo, ukuqinisekisa ukuthotyelwa kwemigangatho yeprojekthi.

Isiphumo seProjekthi kunye neNgxelo yabaThengi

 

Ngeeprofayili zethu zentsimbi ezenziwe ngokwezifiso ezikumgangatho ophezulu kunye nenkxaso yobuchwephesha bobuchwephesha, iprojekthi yokwakha iiofisi zikarhulumente wase-El Salvador yaqhubeka kakuhle kwaye yadlula kuvavanyo olungqongqo lokwamkelwa ziigunya zikarhulumente wasekuhlaleni. Isakhiwo sentsimbi sibonakalise uzinzo oluhle kakhulu kunye nokusebenza kwenyikima, sihlangabezana nemigangatho yokhuseleko ephezulu kwizakhiwo zikarhulumente ezibalulekileyo. Le projekthi ngoku ingenile kwinqanaba lokugqibela lokuhombisa kwaye kulindeleke ukuba isetyenziswe kungekudala, ibonelela ngendawo yeofisi yanamhlanje, ekhuselekileyo, nesebenzayo kumasebe karhulumente wasekuhlaleni.

 

Umthengi uqaphela kakhulu iimveliso kunye neenkonzo zethu:"Ii-H-beams, ii-engile steels, kunye neepleyiti zentsimbi ezivela kwi-ROYAL STEEL ziyahlangabezana ngokupheleleyo neemfuno ezingqongqo zeprojekthi yethu yokwakha karhulumente. Umgangatho wazo ozinzileyo, iinkcukacha ezichanekileyo, kunye nokuthobela imigangatho yamazwe ngamazwe kuye kwabeka isiseko esiqinileyo sokhuseleko lwesakhiwo seprojekthi. Ukuhanjiswa ngempumelelo kwe-ROYAL STEEL kunye nenkxaso yobungcali kwindawo kukwasincede ukuba siphephe ukulibaziseka kokwakhiwa. Siyazingca ngokusebenzisana ne-ROYAL STEEL kwaye sijonge phambili ekusebenzisaneni nezinye iiprojekthi ezibalulekileyo zeziseko zophuhliso e-El Salvador kwixesha elizayo."
