Ziziphi iingenelo kunye neempawu ze-H beam?

H umqaisetyenziswa ngokubanzi kulwakhiwo lwesakhiwo sentsimbi yanamhlanje. Umphezulu wentsimbi yecandelo le-H awunakho ukuthambekela, kwaye iindawo eziphezulu kunye nezisezantsi zihambelana. Uphawu lwecandelo le-H-beam lingcono kunelo lemveliMna - beam, intsimbi yentsimbi kunye nentsimbi yeAngle. Ke zithini iimpawu ze-H beam?

1. Amandla aphezulu esakhiwo

Xa kuthelekiswa ne-I-beam, i-modulus yecandelo likhulu, kwaye imeko yokuthwala iyafana ngexesha elifanayo, isinyithi sinokugcinwa ngo-10-15%.

2. Isitayela sokuyila esithambileyo nesityebileyo

Kwimeko yobude obufanayo bomqadi, ubume bentsimbi buyi-50% enkulu kunesakhiwo sekhonkrithi, okwenza i-layout ibe bhetyebhetye.

3. Ubunzima obulula besakhiwo

Xa kuthelekiswa nesakhiwo sekhonkrithi, ubunzima besakhiwo bulula, ukucuthwa kobunzima besakhiwo, ukunciphisa amandla angaphakathi kuyilo lwesakhiwo, unokwenza isiseko sokwakhiwa kwesiseko iimfuno ziphantsi, ulwakhiwo lulula, iindleko. iyancipha.

4. Uzinzo oluphezulu lwesakhiwo

I-hot rolled H-beam iyona sakhiwo sentsimbi engundoqo, isakhiwo sayo singokwenzululwazi kwaye sinengqiqo, iplastiki efanelekileyo kunye nokuguquguquka, ukuzinza okuphezulu kwesakhiwo, okufanelekileyo ukuthwala ukungcangcazela kunye nomthwalo wempembelelo yesakhiwo esikhulu sokwakha, ukukwazi ukuchasana neentlekele zendalo, ezilungele ngakumbi ezinye izakhiwo kwiindawo zenyikima. Ngokwezibalo, kwihlabathi elinobukhulu obusi-7 okanye ngaphezulu kwentlekele yenyikima etshabalalisayo, intsimbi emile okwe-H ubukhulu becala izakhiwo zentsimbi zichaphazeleke kancinci.

5. Ukwandisa indawo yokusetyenziswa ngokufanelekileyo kwesakhiwo

Xa kuthelekiswa nesakhiwo sekhonkrithi, indawo yekholomu yesakhiwo sensimbi incinci, enokunyusa indawo yokusetyenziswa ngokufanelekileyo kwesakhiwo, kuxhomekeke kwiindlela ezahlukeneyo zesakhiwo, inokunyusa indawo yokusetyenziswa ngokufanelekileyo kwe-4-6%.

6. Gcina abasebenzi kunye nezixhobo

Xa kuthelekiswa nentsimbi ye-welding ye-H-beam, inokusindisa kakhulu abasebenzi kunye nezixhobo, ukunciphisa ukusetyenziswa kwezinto eziluhlaza, amandla kunye nabasebenzi, uxinzelelo oluphantsi lwentsalela, inkangeleko entle kunye nomgangatho womphezulu.

7. Kulula ukusetyenzwa ngoomatshini

Kulula ukuncamathisela kunye nokuyifaka ngokwesakhiwo, kodwa kulula ukuyisusa kunye nokusetyenziswa kwakhona.

8. Ukhuseleko lokusiNgqongileyo

Ukusetyenziswa kweIntsimbi yecandelo le-Hinokukhusela ngokufanelekileyo indawo engqongileyo, ebonakaliswa kwiinkalo ezintathu: okokuqala, xa kuthelekiswa nekhonkrithi, inokusebenzisa ukwakhiwa okomileyo, okubangelwa ingxolo encinci kunye nothuli oluncinci; Okwesibini, ngenxa yokunciphisa ubunzima, ukukhutshwa komhlaba ongaphantsi kokwakhiwa kwesiseko, umonakalo omncinci kwimithombo yomhlaba, ukongeza ekunciphiseni okukhulu komthamo wekhonkrithi, ukunciphisa inani lokwembiwa kwamatye, ukukhuthaza ukukhuselwa kwendalo yendalo; Okwesithathu, emva kokuba ubomi benkonzo yesakhiwo sokwakha buphelile, inani lenkunkuma eqinile eyenziwa emva kokuba isakhiwo sichithwa sincinci, kwaye ixabiso lokuphinda lisetyenziswe kwimithombo yensimbi ye-scrap liphezulu.

9. Iqondo eliphezulu lemveliso yoshishino

Isakhiwo sensimbi esekelwe kwi-hot rolled beam ye-H inomgangatho ophezulu wemveliso yemveliso, ekulungele ukuveliswa koomatshini, imveliso enzulu, ukuchaneka okuphezulu, ukufakwa okulula, ukuqinisekiswa kwekhwalithi elula, kwaye inokwakhiwa kwimizi-mveliso yokwenyani yendlu, ukuveliswa kwebhulorho. umzi-mveliso, umzi-mveliso wokuvelisa imveliso yezityalo, njl njl. Uphuhliso lwesakhiwo sentsimbi ludale kwaye lwaqhuba uphuhliso lwamakhulu amashishini amatsha.

10. Isantya sokwakha sikhawuleza

Unyawo oluncinci, kwaye lufanelekile ukwakhiwa kwemozulu yonke, impembelelo encinci yeemeko zemozulu. Isantya sokwakhiwa kwesakhiwo sensimbi esenziwe nge-hot rolled beam H malunga namaxesha angama-2-3 kweso sakhiwo sekhonkrithi, i-capital turnover rate iphindwe kabini, iindleko zemali ziyancipha, ukwenzela ukugcina utyalo-mali. Ukuthatha "iJinmao Tower" ePudong yaseShanghai, "esona sakhiwo sikhulu kunazo zonke" eChina njengomzekelo, umzimba oyintloko wesakhiwo esinobude obuphantse ube yi-400m sagqitywa ngaphantsi kwesiqingatha sonyaka, ngelixa isakhiwo sentsimbi-concrete sasifuna ezimbini. iminyaka yokugqiba ixesha lokwakha.
