INKQUBO YOKUVELISWA KWEMVELISO
Iflange yeH umqaihambelana okanye iphantse yangqamana ngaphakathi nangaphandle, kwaye isiphelo seflange sikwi-Engile yasekunene, ngoko ibizwa ngokuba yi-parallel flange I-steel.Ubukhulu bewebhu yentsimbi emise okwe-H buncinci kunobo bemiqadi ye-I eqhelekileyo enobude obufanayo bewebhu, kwaye ububanzi beflange bukhulu kunobo bemiqadi ye-I eqhelekileyo enobude obufanayo bewebhu, ke ikwabizwa ngokuba yi-wide-rim I-beams.Ukumiselwa kwimilo, i-modulus yecandelo, umzuzu we-inertia kunye namandla ahambelanayo we-H-beam ngokucacileyo ungcono kune-I-beam eqhelekileyo enobunzima obufanayo.Isetyenziswe kwiimfuno ezahlukeneyo zesakhiwo sesinyithi, nokuba iphantsi kwe-torque yokugoba, umthwalo woxinzelelo, umthwalo we-eccentric ubonisa ukusebenza kwawo okuphezulu, unokuphucula kakhulu umthamo wokuthwala kune-I-steel eqhelekileyo, ukugcina isinyithi 10% ~ 40%.Intsimbi emile okwe-H ine-flange ebanzi, iwebhu encinci, inkcazo emininzi, kunye nokusetyenziswa okuguquguqukayo, okunokugcina i-15% ukuya kwi-20% yesinyithi kwizakhiwo ezahlukeneyo ze-truss.Ngenxa yokuba i-flange yayo ihambelana ngaphakathi nangaphandle, kwaye isiphelo somphetho sikwi-Angle elungileyo, kulula ukudibanisa kunye nokudibanisa kumacandelo ahlukeneyo, anokugcina malunga ne-25% yomthwalo welding kunye ne-riveting, kwaye inokukhawulezisa kakhulu isantya sokwakha. yeprojekthi kunye nokunciphisa ixesha lokwakha.

IIMBONAKALO
Kukho iinkcukacha ezininzi zemveliso yeH-umqadi, kunye neendlela zokuhlela zezi zilandelayo.(1) Ngokobubanzi beflange yemveliso, yahlulahlulwe ibe yiflange ebanzi, iflange ephakathi kunye neflange emxinwa H-umqadi. inkulu kuno okanye ilingana nobude bewebhu H. Ububanzi beflange B bentsimbi emxinwa yeflange emilise okwe-H bulingana nesiqingatha sobude becwecwe lewebhu. yahlulwe yaba yintsimbi yohlobo lwe-H, i-H-uhlobo lwekholamu yensimbi, i-H-type yentsimbi kunye ne-H-type yentsimbi ene-flange enzima kakhulu. ye-H-beams. Ngokuqhelekileyo, i-flange emxinwa yentsimbi ye-H-beam isetyenziswa njengentsimbi kunye ne-flange ebanzi ye-H-beam yentsimbi isetyenziswa njengekholamu.Ngokufanelekileyo, ikwabizwa ngokuba yintsimbi ye-H-beam kunye nekholamu yentsimbi ye-H.(3) Ngokwendlela yokuvelisa, ihlulwe ibe yintsimbi edibeneyo ye-H-beam kunye nentsimbi ye-H-beam.(4) Ngokweenkcukacha zobukhulu zihlukaniswe zibe yintsimbi enkulu, ephakathi kunye nencinci ene-H. Ngokuqhelekileyo, iimveliso ezinobude bewebhu H ngaphezu kwe-700mm zibizwa ngokuba zinkulu, i-300 ~ 700mm zibizwa ngokuba ziphakathi, kwaye ezo zingaphantsi kwe-300mm zibizwa ngokuba zincinci. Ekupheleni kuka-1990, eyona ndawo inkulu yehlabathi ye-H-beam ukuphakama kwe-1200mm, ububanzi obuyi-530mm.
UKUHLOLWA KWEMVELISO
Iimfuno zokuhlola intsimbi emile okwe-H ikakhulu ziquka le miba ilandelayo:
Umgangatho wokubonakala: Umgangatho wembonakalo yentsimbi ye-H kufuneka ihambelane nemigangatho efanelekileyo kunye neemfuno zokuyalela.Umphezulu kufuneka ube bushelelezi kwaye ube tyaba, ngaphandle kwezibonda ezicacileyo, imikrwelo, umhlwa kunye nezinye iziphene.
Imilinganiselo yejometri: Ubude, ububanzi, ukuphakama, ubukhulu bewebhu, ubukhulu be-flange kunye nobunye ubungakanani bentsimbi efana ne-H kufuneka ihambelane nemigangatho efanelekileyo kunye neemfuno zokuodola.
I-Curvature: I-curvature yensimbi ene-H kufuneka ihambelane nemigangatho efanelekileyo kunye neemfuno zokuyalela.Inokubonwa ngokulinganisa ukuba iindiza kuzo zombini iziphelo zentsimbi efana ne-H zihambelana okanye zisebenzisa imitha yokugoba.
I-twist: I-twist yentsimbi e-H kufuneka ihambelane nemigangatho efanelekileyo kunye neemfuno zokuyalela.Inokubonwa ngokulinganisa ukuba icala lentsimbi emise okwe-H lithe nkqo okanye ngemitha ye-twist.
Ukuphambuka kobunzima: Ubunzima bentsimbi efana ne-H kufuneka buhambelane nemigangatho efanelekileyo kunye neemfuno zokuyalela.Ukuphambuka kobunzima kunokubonwa ngobunzima.
Ukubunjwa kweMichiza: Ukuba i-H-shaped steel idinga ukudityaniswa okanye iqhutywe ngenye indlela, ukubunjwa kwayo kweekhemikhali kufuneka kuhambelane nemigangatho efanelekileyo kunye neemfuno zokuyalela.
Iimpawu zomatshini: Iimpawu zomatshini zentsimbi ene-H kufuneka zihambelane nemigangatho efanelekileyo kunye neemfuno zokuyalela, kubandakanywa amandla okuqina, isivuno, ukunyuswa kunye nezinye izibonakaliso.
Uvavanyo olungonakalisiyo: Ukuba i-H-shaped steel idinga uvavanyo olungenakonakala, kufuneka luvavanywe ngokuhambelana nemigangatho efanelekileyo kunye neemfuno zokuyalela ukuqinisekisa ukuba umgangatho wayo wangaphakathi ulungile.
Ukupakishwa kunye nokumakishwa: Ukupakishwa kunye nokumakishwa kwensimbi ene-H kufuneka ihambelane nemigangatho efanelekileyo kunye neemfuno zokuyalela ukuququzelela ukuthutha kunye nokugcinwa.
Ngamafutshane, ezi mfuno zingentla kufuneka ziqwalaselwe ngokupheleleyo xa kuhlolwa intsimbi emise okwe-H ukuze kuqinisekiswe ukuba umgangatho wayo uhlangabezana nemigangatho efanelekileyo kunye neemfuno zokuodola, kunye nokubonelela abasebenzisi ngemveliso yentsimbi ye-H.
Isicelo
EqhelekileyoH-umqadiizinto zensimbi ziquka i-Q235B, i-SM490, i-SS400, i-Q345 kunye ne-Q345B.Ukwakheka kweekhemikhali kunye neempawu zomatshini ezi zinto zihlukile, ngoko xa ukhetha ukusetyenziswa kwe-H-beam, kuyimfuneko ukukhetha izinto ezifanelekileyo ngokwemeko ethile.
UKUPAKISHA NOKUTHUMELA
Ukupakishwa kunye nokhuseleko:
Ukupakishwa kudlala indima ebalulekileyo ekukhuseleni umgangatho we-ASTM A36H umqaintsimbi ngexesha lokuthutha kunye nokugcinwa.Izinto eziphathekayo kufuneka zigcinwe ngokukhuselekileyo, zisebenzisa iintambo eziphezulu okanye iibhanti zokukhusela ukunyakaza kunye nomonakalo onokwenzeka.Ukongezelela, amanyathelo kufuneka athathwe ukukhusela intsimbi ekuchaseni ukufuma, uthuli kunye nezinye izinto zokusingqongileyo.Ukusonga iinyanda kwizinto ezikwaziyo ukumelana nemozulu, njengeplastiki okanye ilaphu elingangenwa ngamanzi, kunceda ukukhusela ekudlekeni nasekugqweni.
