Izindaba - Umhlahlandlela Ophelele We-W Beams: Ubukhulu, Izinto Ezisetshenziswayo, kanye Nokucatshangelwa Kokuthenga

imisebe engu-W, ziyizinto eziyisisekelo zesakhiwo kwezobunjiniyela nokwakha, ngenxa yamandla azo kanye nokuguquguquka kwazo. Kulesi sihloko, sizohlola ubukhulu obuvamile, izinto ezisetshenzisiwe, kanye nezihluthulelo zokukhetha ugongolo lwe-W olufanele lwephrojekthi yakho, kufaka phakathi okufanaUmsebe ongu-14x22 W, Umsebe ongu-16x26 W, Umsebe we-ASTM A992 W, futhi nokuningi.

Ukucwila Ngokujulile Emisebeni Ye-H Egxile Ku-ASTM A992

Kuyini umsebe we-W?

I-AW beam iyiphrofayili yensimbi enesigaba esinqunyiwe esimise okwe-"W", esakhiwe umgodi (isigaba esimaphakathi esiqondile) kanye nama-flange amabili (izingxenye ezivundlile ezinhlangothini). Le geometry inikeza ukumelana okuhle kakhulu nokugoba nomthwalo, okwenza kube kuhle kakhulu ezisekelweni zesakhiwo ezakhiweni, emabhulohweni, kanye namaphrojekthi ezimboni. Amagama athi i-W-beam, i-W-profile, kanye ne-W-beam avame ukusetshenziswa ngokushintshana ukubhekisela kulolu hlobo lwephrofayili.

Ubukhulu Obuvamile Be-W-Beam

Ubukhulu be-W-beam buchazwa ukuphakama kwabo okuphelele (kukalwa kusukela kolunye uhlangothi lwe-flange kuya kolunye) kanye nesisindo ngonyawo oluqondile, yize ngezinye izikhathi kubizwa ngokuthi ukuphakama nobubanzi be-flange ngokufingqiwe. Ezinye zezilinganiso ezithandwa kakhulu zifaka:
Ugongolo lwe-W oluyi-12x16: Cishe ubude bayo bungamasentimitha angu-12, isisindo sayo singamakhilogremu angu-16 ngefithi.
Ugongolo lwe-6x12 W: 6 amayintshi ukuphakama, isisindo esingamakhilogremu angu-12 ngefithi, ilungele ukusetshenziswa okuncane.
Ugongolo lwe-W oluyi-14x22: 14 inches ukuphakama, isisindo esingamakhilogremu angu-22 ngefithi, esetshenziswa ezakhiweni eziphakathi nendawo.
Ukukhanya okungu-16x26 W: Njengoba iphakeme ngamasentimitha angu-16 futhi inesisindo esingamakhilogremu angu-26 ngefithi, ifanelekela imithwalo esindayo.

Insimbi ye-W-beam esetshenziswa kakhulu ihlangabezana nezindinganiso ze-ASTM A992, ezichaza insimbi esebenza kahle kakhulu enamandla okukhiqiza angu-50 ksi (amakhilogremu angu-50,000 nge-intshi yesikwele). Le nsimbi yaziwa ngalokhu:
Ukumelana kwayo nokugqwala uma iphathwa ngemithi yokuzivikela.
Ukuqina kwayo, okuvumela ukuguquguquka okulawulwayo ngaphandle kokuphuka.
Ikhono layo lokubekezelela imithwalo engaguquki neguquguqukayo, okwenza ifaneleke kakhulu ezindaweni ezinzima.
Ngaphezu kweInsimbi ye-ASTM A992, imisebe ye-W ingatholakala nakwezinye izinhlobo zensimbi, njenge-ASTM A36, yize i-A992 ithandwa kakhulu kumaphrojekthi amakhulu esakhiwo ngenxa yamandla ayo amakhulu.

Izinto Ezibalulekile Okufanele Uzicabangele Lapho Uthenga Ama-W-Beams

Chaza Izidingo Zobuchwepheshe
Imithwalo Esekelayo: Bala imithwalo engaguquki (eyisisindo sakho) kanye nemithwalo enamandla (ehambayo) ezosekelwa yi-beam. Amamodeli afana ne-16x26 W-beam afanelekela imithwalo esindayo, kanti i-6x12 W-beam ingcono ezakhiweni ezincane.
Ubude Obudingekayo: Ama-W-beam akhiqizwa ngobude obujwayelekile, kodwa angenziwa ngokwezifiso zephrojekthi ngayinye. Qiniseka ukuthi ubude ngeke bubangele izinkinga zokuhamba noma zokufakwa.

Qinisekisa i-Standard kanye ne-Material
Qiniseka ukuthi ugongolo luhlangabezana nezindinganiso ze-ASTM A992 uma kuyiphrojekthi enkulu yokwakha, njengoba lokhu kuqinisekisa izakhiwo ezifanayo zemishini.
Hlola ikhwalithi yensimbi: kumele ibonise izimpawu ezisemthethweni zomkhiqizi kanye nezitifiketi zokuhambisana nezindinganiso zomhlaba wonke.

Hlola Umhlinzeki
Ngithanda abakhiqizi abanolwazi ngensimbiImisebe engu-Wkanye nedumela emakethe. Bheka izinkomba bese ubuyekeza amaphrojekthi abo angaphambilini.

Qhathanisa amanani, kodwa ungakhohlwa ukuthi ikhwalithi yezinto ezibonakalayo ibaluleke kakhulu kunentengo ephansi. Imisebe ye-W esezingeni eliphansi ingaholela ekuhlulekeni kwesakhiwo ngokuhamba kwesikhathi.

Cabanga Ngokwelashwa Komphezulu
Ama-W-beams abekwe endaweni ezungezile kufanele abe nokwelashwa kokulwa nokugqwala, njengopende we-epoxy noma i-galvanization. Lokhu kwandisa ukuqina kwawo, ikakhulukazi ezindaweni ezinomswakama noma usawoti.

Qinisekisa Isicelo Esiqondile
Kumaphrojekthi afana namabhuloho noma izakhiwo ezinde, ukukhethwa kwe-W-beam kufanele kwenziwe kanye nonjiniyela wezakhiwo, ozonquma ubukhulu nezinto ezifanele ngokusekelwe ezindinganisweni zendawo kanye nezidingo zomthwalo.

Imishayo engu-W iyizinto ezibalulekile ekwakheni kwesimanje, futhi ukukhetha kwayo okufanele kuncike ekuqondeni ubukhulu bayo (njengemishayo engu-14x22 W noma imishayo engu-12x16 W), izinto zokwakha (ikakhulukazi insimbi ye-ASTM A992), kanye nezidingo zephrojekthi. Uma uthenga, beka phambili ikhwalithi, ukuhambisana nezindinganiso, kanye nedumela lomhlinzeki, ngaleyo ndlela uqinisekise ukuphepha nokuqina kwesakhiwo sakho.
