Indlela yokukhetha i-H Beam kwiProjekthi yakho

Kwimeko etshintsha ngokukhawuleza yobunjineli bezakhiwo nobokwakha,Umqadi we-H(okanyeumqadi weflengi ebanziUkukhetha kudlala indima ebaluleke kakhulu kukhuseleko, uzinzo kunye noqoqosho lweprojekthi yonke. Ukusuka kwisakhiwo esiphakamileyo ukuya kwindawo yokugcina impahla yemizi-mveliso, ukusuka kwibhulorho ukuya kwisakhiwo sezorhwebo, ukhetho olungalunganga lwe-H beam lunokubangela ingxaki kwisakhiwo, iindleko ezigqithisileyo, okanye umngcipheko wobomi.

Izinto ezibalulekileyo ekukhetheni i-H Beam efanelekileyo

Isiseko sokukhetha siqala ngokwazi imithwalo ekufuneka ithwalwe ngumqadi. Phakathi kwezi zinto kukho:

1. Imithwalo Efileyo (Ubunzima Obuhlala Buhleli Besakhiwo Ngokwaso)

2. Imithwalo ephilayo (abantu, ifenitshala, iimoto, ikhephu, nokunye)

3. Imithwalo enamandla (umoya, amandla enyikima)

Iingcali zobunjineli bezakhiwo zisebenzisa isoftware yohlalutyo lwezakhiwo okanye iikhowudi zoyilo (umzekelo, i-AISC e-US, i-Eurocode eYurophu, okanye imigangatho ye-GB eTshayina) ukubala amaxesha okugoba, amandla okucheba, kunye nemida yokuphambuka.

Ubude beSpan kunye neMeko yeNkxaso

Ii-long span zifuna imisebe ene-inertia enkulu ukuze kuncitshiswe ukuphambuka. Umzekelo:

1. Iindawana ezimfutshane (ukuya kuthi ga kwi-6-8m) kwiindawo zokuthengisa ezilula zihlala zenziwa ngamacandelo amancinci ~ 150-200 mm ukuphakama.

2. Ii-span eziphakathi (iinyawo ezingama-26-49) kwiindawo zokugcina impahla zihlala zifuna imisebe ye-H eyi-10-14" H.

3. Iispan ezinkulu okanye imisebenzi enzima (iibhulorho, iiholo ezinkulu zemizi-mveliso) zifuna iindawo ezingama-400 mm+ okanye amanqanaba atyebileyo.

Udidi lwezinto kunye namandla azo

Iindidi zentsimbi ezisetyenziswa rhoqo zezi:

1.Umqadi we-ASTM A36 / A572 / A992 H(Umgangatho wase-US, amandla okuvelisa aqikelelweyo angama-250-345 MPa)

2.Umqadi we-EN S235 / S275 / S355 H(Isiqhelo saseYurophu)

3.GB Q235 / Q345 H Beam (umgangatho wesiTshayina)

Amanqanaba aphezulu (umz., Q345B okanye S355) avumela iindawo ezikhaphukhaphu kumthwalo ofanayo, nto leyo enciphisa ubunzima bezinto kunye neendleko zesiseko - oku kunomtsalane ngakumbi kwiindawo ezinenyikima okanye kulwakhiwo oluphezulu.

Ubungakanani kunye neNkcazelo yoBume

Imiqadi ye-H ichazwa ngokuphakama × ububanzi × ubukhulu bewebhu × ubukhulu beflange (i-metric) okanye ubunzulu obuqhelekileyo + ubunzima ngenyawo (ubukumkani, umz., i-W8×40).

Ubukhulu obudumileyo buquka:

1. Umsebenzi olula: 100×100 mm ukuya kwi-200×100 mm

2. Umsebenzi oPhakathi: 250×250 mm ukuya kwi-300×300 mm

3.Umsebenzi onzima: 400×200 mm nangaphezulu

Soloko ubhekisa kwiitshathi zobukhulu obuqhelekileyo ukuze ufumane iipropati zecandelo (umzuzu wokungakhathali, imodyuli yecandelo, ubunzima ngemitha nganye) ukuze zihambelane neemfuno zeprojekthi.

Izinto eziqwalaselwayo kwiNdalo nakwiProjekthi ethile

Ukumelana nokugqwala: Sebenzisa intsimbi eqinisiweyo, epeyintiweyo, okanye eshushu (umz., iCorten) kwiindawo ezingaphandle okanye ezifumileyo nezifumileyo.

Ukuwelda kunye nokukwazi ukwakheka: Qinisekisa ukuba umgangatho uyahambelana neenkqubo zokuwelda ezisetyenziswa kwindawo leyo.

Ixabiso kunye nokufumaneka: Cinga ngendlela esebenza ngayo xa kuthelekiswa neekhonkco zobonelelo lwendawo—ukunika iinkcukacha ezigqithisileyo kunokunyusa iindleko ngama-20–50%.

Nxibelelana neengcali

Ukubhala ikhowudi yokuqala kungasebenzisa ii-calculator ezikwi-intanethi okanye iitafile zesikwere, kodwa ukhetho lokugqibela kufuneka luqinisekiswe yinjineli yesakhiwo enelayisenisi. Ubungakanani obuqhelekileyo buya kuhambelana nekhowudi kwaye bube nesakhiwo esifanelekileyo - bungaxhomekeki kubalo olusemthethweni kuphela.
