Q4 Yiziphi izinto ezicatshangelwayo zokufakwa kwendawo yephaneli yokudonsa?

Ukuze uthole indawo yokugezela, igumbi lemishini, njll. kudingeka ukwehlisa ipuleti, qiniseka ukuthi ubheka ukuthi imidwebo yezakhiwo kanye nemidwebo yesakhiwo iyahambisana yini, uma udinga ukwehlisa ipuleti, yehlisa ipuleti endaweni yemishayo yensimbi. idinga ukungezwa ku-joist ngaphambi kokuthela i-slab yaphansi kakhonkolo.

Q5 Yiziphi izinto ezicatshangelwayo zokufakwa kwekholomu eqala phezu kogodo?

Ukuze ugongolo up ikholomu nodes, uma ikholomu yensimbi iphezulu, it is hhayi Kunconywa ukusebenzisa ikholomu steel is hhayi izigaba, on-site positioning indlela Welding, isizathu siwukuthi ukuma kwekholomu yensimbi ngokuvamile ayishiselwe ngokushesha ngemva. ikholomu yensimbi idinga ukulungiswa ngokuqinile ngekhebula, ngaphandle kwalokho kunengozi yokugumbuqela; okwesibili ikholomu ephakeme yensimbi ukufakwa esizeni akulungile ukutholakala, uma kunephutha ekumisweni kokusebenza kabusha kwenani lomsebenzi likhulu.

Q6 Yiziphi izinto ezicatshangelwayo zokufakwa kwamanodi aphezulu ekholomu?

Ipuleti lokuvala lekholomu eliphezulu akufanele lenziwe libe yindlela yokuqina kwangaphakathi, kufanele libe likhulu kancane kunengxenye ephambanayo yekholomu yensimbi, ukuvimbela ukuvuza kwamanzi ezinsukwini zemvula; ngaphezu kwalokho, ukuphakama okuphezulu kwekholomu kufanele kube ngaphezulu kunesiqongo se-20-50mm ukuze kuqinisekiswe ukuthi ukuxhumana kwekholomu ye-beam emaphethelweni osayizi wonyawo lwe-flange weld ngokuhambisana nezidingo zokucaciswa.

Q7 Yiziphi izinto ezicatshangelwayo zokufakwa kwe-steel joist joist floor?

I-reinforced truss floor joist iyinhlanganisela yesifanekiso esishisela insimbi yensimbi kanye nepuleti lensimbi yokuminyanisa libe yinye, enciphisa ukumiswa nokuhlakazwa kwesifanekiso, futhi enezici zomnotho, lula, ukuphepha nokwethembeka. Ukwakhiwa kwe-steel joist joist yokuhlanganisa kufanele kube ukuhleleka okunengqondo, kunciphise ukulahlekelwa kanye nokusika endaweni, futhi unyawo lokushisela impande kufanele lulingane futhi lugcwale lapho kushiselwa amabhawodi esizeni.
