Imiqadi yentsimbi—efana nemiqadi ye-H kunye nemiqadi ye-W—isetyenziswa kwiibhulorho, kwiindawo zokugcina impahla, nakwezinye izakhiwo ezinkulu, kwanakwiifreyimu zoomatshini okanye zeelori.
U-"W" kwi-W-beam umele "i-flange ebanzi." U-H beam ngumqadi obanzi.
AMAZWI OMNANDI AVELA KUBATHENGI BAM ABATHANDEKAYO
Icala lasekhohlo libonisa umqadi ongu-W, kwaye icala lasekunene libonisa umqadi ongu-H
UMqadi W
Intshayelelo
Igama elithi "W" egameni le-W beam limele "i-flange ebanzi." Umahluko ophambili phakathi kwe-W beams kukuba imiphezulu yayo ye-flange yangaphakathi neyangaphandle iyalingana. Ngaphezu koko, ubunzulu be-beam bufanele bulingane ubuncinane nobubanzi be-flange. Ngokwesiqhelo, ubunzulu bukhulu kakhulu kunobubanzi.
Enye inzuzo yemitha ye-W kukuba iiflange zijiyile kunewebhu. Oku kunceda ukumelana noxinzelelo lokugoba.
Xa kuthelekiswa nemisebe ye-H, imisebe ye-W ifumaneka kwiindawo ezinqamlezileyo eziqhelekileyo. Ngenxa yobubanzi bayo obukhulu (ukusuka kwi-W4x14 ukuya kwi-W44x355), ithathwa njengeyona misebe isetyenziswa kakhulu kulwakhiwo lwanamhlanje kwihlabathi liphela.
I-A992 W beam yeyona ndlela yethu ithengiswa kakhulu.
I-H BAM
Intshayelelo
Imiqadi ye-H yeyona miqadi mikhulu nenzima ekhoyo, ekwaziyo ukuxhasa imithwalo enzima kakhulu. Ngamanye amaxesha ikwabizwa ngokuba yi-HP, ii-H-piles, okanye ii-load-bearing piles, isalathiso sokusetyenziswa kwazo njengeziseko ezingaphantsi komhlaba (iikholamu ezithwala imithwalo) kwizakhiwo eziphakamileyo nakwezinye izakhiwo ezinkulu.
Njengeemitha ze-W, iimitha ze-H zinemiphezulu yeflange yangaphakathi neyangaphandle ehambelanayo. Nangona kunjalo, ububanzi beflange yomqadi we-H buphantse bulingane nokuphakama komqadi. Umqadi ukwanayo nobukhulu obufanayo kuyo yonke indawo.
Kwiiprojekthi ezininzi zokwakha nezobunjineli, imiqadi isebenza njengesiseko senkxaso. Ziluhlobo nje lwentsimbi yokwakha, kodwa ekubeni kukho iintlobo ezininzi ezahlukeneyo zemiqadi ezikhoyo, kubalulekile ukukwazi ukwahlula phakathi kwazo.
Ngaba ufundile ngakumbi nge-H beams kunye ne-W beams emva kwentshayelelo yanamhlanje? Ukuba ungathanda ukufunda okungakumbi malunga nobuchule bethu, nceda unxibelelane nathi ukuze sixoxe.
