Le projekthi yifreyimu yendawo esetyhula / ubude buziimitha ezingama-44.55 / ubude bubonke buziimitha ezingama-332 / ubude bubonke buziimitha ezingama-77.2.
1. Zonke i-purlins ezingentla zishushu-dip galvanized rectangular steel purlins, isixa se-galvanizing yi-250 ~ 275g / m, kunye nezinto eziphathekayo yi-Q235B.
2. Ubungakanani besiza kufuneka buhlolwe phambi kokwakhiwa kwesakhiwo.
3. Okunye okungachazwanga kuya kuhambelana nemigangatho yesizwe yangoku.
4. Ulandelelwano lokufakela lu: ukuthwala ibhola - ibhola yentambo ephantsi, intonga - intonga yesisu - ibhola yomtya ophezulu, intonga.
Intsimbi: Ngaphandle kokuba kuchazwe ngenye indlela, yonke imibhobho yentsimbi yenziwe ngentsimbi ye-Q235B.Ukubunjwa kwayo kweekhemikhali kunye neepropati zomatshini ziya kuhambelana nemimiselo yomgangatho wangoku "i-Carbon Structural Steel" (GB/T700-2006).Amandla okuqina, ubude, inqaku lesivuno, uvavanyo lokugoba olubandayo kunye nokuqina kwempembelelo yezinto kufuneka kuqinisekiswe ukuba kufanelekile, kwaye umxholo wesulfure, i-phosphorus kunye nekhabhoni kufuneka uqinisekiswe ukuhlangabezana neemfuno.Ukunyamezela kobunzima bentsimbi yentsimbi kuya kuhlangabezana neemfuno zentsebenzo ye-seismic yentsimbi "kwiMilinganiselo, iiMilo, ubunzima kunye nokunyamezelwa kweePlati ze-Stili eziQinisekisiweyo kunye neeMicu":
I-1) Umlinganiselo wexabiso elilinganisiweyo lomlinganiselo wemveliso yentsimbi ukuya kwixabiso elilinganisiweyo lamandla obunzima akufanele libe ngaphezu kwe-0.85;
2) Intsimbi kufuneka ibe namanyathelo okuvelisa acacileyo, kwaye i-elongation akufanele ibe ngaphantsi kwe-20%;
3) Intsimbi kufuneka ibe ne-weldability elungileyo kunye nokuqina kwempembelelo efanelekileyo.
