Izakhiwo zohlaka lwesikhala zidlala indima ebalulekile ekwakhiweni kwezakhiwo zanamuhla kanye nokwakhiwa kwezimboni. Onjiniyela bayazazisa ngokusatshalaliswa kwazo komthwalo okumangalisayo, ukuziphatha okulula, kanye nokuguquguquka kwejometri. Kusukela ezikhumulweni zezindiza nasezinkundleni zemidlalo kuya ezitshalweni zezimboni kanye namahholo ombukiso, ohlaka lwesikhala luvumela izindawo ezinkulu ezingenazo izinsika zangaphakathi. Ukwamukelwa kwazo okukhula kubonisa kokubili ukuvuthwa kobuchwepheshe kanye nokusebenza kahle kwezomnotho.Isitsha Esiqandisayo
Iyini Isakhiwo Sohlaka Lwesikhala
Uhlaka lwesikhala luhlelo lwesakhiwo olunezinhlangothi ezintathu olwakhiwe ngamalungu aqondile axhumene ahlelwe ngendlela yejiyometri. Izinhlelo eziningi zithembele kumayunithi angunxantathu ngoba onxantathu banikeza ukuzinza kwejiyometri okungokwemvelo. Ngokungafani nama-trus ahleliwe, ohlaka lwesikhala basakaza imithwalo ngezilinganiso ezintathu, okunciphisa ukugxilisa ingqondo.
Amalungu ohlaka lwesikhala ajwayelekile asebenzisa izingxenye zensimbi eziyindilinga noma eziyisikwele. Amazinga ajwayelekile ensimbi afaka phakathi i-Q235, i-Q355, i-ASTM A36, kanye ne-ASTM A572. Lezi zinto zinikeza amandla okukhiqiza asukela ku-235 MPa kuya ku-355 MPa, okusekela izinhlelo zokusebenza zesikhathi eside.
Ukuxhumeka kwama-node kuchaza ukusebenza kwesistimu. Ama-bolt ball joints, ama-welded joints, nama-cast steel nodes alawula imakethe. Ama-bolt spherical joints avame ukufeza amandla okubamba angaphezu kuka-500 kN nge-node ngayinye, kuye ngobubanzi kanye ne-bolt grade. Ukwenziwa kahle kuqinisekisa ukubekezelelana okuqinile, ngokuvamile ngaphakathi kuka-±1.5 mm ngobude belungu.
Onjiniyela bavame ukusebenzisa ozimele besikhala ezindaweni eziphakathi kwamamitha angu-30 no-120. Amanye amaphrojekthi amakhulu adlula amamitha angu-200 nge-geometry ethuthukisiwe. Uma kuqhathaniswa nezinhlelo zemishayo yendabuko, uhlaka lwesikhala lunganciphisa ukusetshenziswa kwensimbi ngo-15% kuya ku-30% ngenxa yobubanzi obufanayo nezimo zomthwalo. Lokhu kunciphisa kunciphisa ngqo izidingo zesisekelo nezindleko zokwakha.
Izinzuzo Zokusebenza Nobunjiniyela Bohlaka Lwesikhala
Izakhiwo zohlaka lwesikhala zithola ukusebenza kahle kwesakhiwo ngenxa yokudluliselwa kwamandla kwazo okunezinhlangothi ezintathu. Imithwalo esetshenziswa noma nini isabalalisa kumalungu amaningi, okuthuthukisa ukuphindaphinda. Lokhu kuziphatha kuthuthukisa ukuphepha, ikakhulukazi ngaphansi kwemithwalo engalingani njengomoya noma ukukhukhuleka kweqhwa.
Isilinganiso samandla nesisindo sihlala singenye yezinzuzo ezibaluleke kakhulu. Uphahla olujwayelekile lwesikhala lunesisindo esiphakathi kwama-25 nama-45 kg ngemitha yesikwele, kuye ngokuthi ububanzi bungakanani kanye nomthwalo womklamo. Izinhlelo zophahla lwekhonkrithi eziqinisiwe zivame ukwedlula ama-120 kg ngemitha yesikwele ngemitha yesikwele efanayo. Isisindo esiphansi somuntu siqu kunciphisa amandla okuzamazama komhlaba, akhula ngobunzima.
Amafreyimu esikhala asebenza kahle ngaphansi kwesenzo sokuzamazama komhlaba. Izindlela eziningi zomthwalo zivumela ukushabalaliswa kwamandla ngaphandle kokwehluleka okungazelelwe. Amakhodi amaningi kazwelonke, kufaka phakathi i-EN 1998 kanye ne-GB 50011, aqaphela amafreyimu esikhala njengezinhlelo zokuzamazama komhlaba ezinhle uma zichazwe kahle.
Ukuhlanganiswa kokushisa kanye nensizakalo nakho kuyazuza nge-geometry evulekile. Abaklami bangahambisa amapayipi e-HVAC, izibani, ama-sprinklers, kanye nama-cable tray ngokujula kwesakhiwo. Lokhu kuhlanganiswa kunciphisa ukuphakama kophahla kanye nomthamo wesakhiwo sonke. Emahholo amakhulu ebhizinisi, le ndlela inganciphisa ukusetshenziswa kwamandla kwaminyaka yonke ngo-5% kuya ku-8% ngenxa yomthamo womoya ophansi.
Izindlela Zokwakha kanye Nokucatshangelwa Kwezindleko Zohlaka Lwesikhala
Abakhiqizi bavame ukwakha izingxenye zohlaka lwesikhala ezindaweni ezilawulwayo zefektri. Ukusika kwe-CNC kanye nokushisela okuzenzakalelayo kuqinisekisa ikhwalithi ehambisanayo. Ukwenziwa kwefektri kungafinyelela amazinga okusetshenziswa kwezinto ezingaphezu kuka-95%, okunciphisa imfucuza.
Ukuhlanganiswa endaweni kulandela izimiso ze-modular. Abasebenzi bahlanganisa amalungu nama-node besebenzisa ama-bolt noma izikhonkwane ezinamandla aphezulu. Kumaphrojekthi aphakathi nendawo, umkhiqizo wokufakwa uvame ukufinyelela kumamitha-skwele ayi-150 kuya kwangu-250 ngosuku ngeqembu ngalinye. Umthamo wokuphakamisa ama-crane uvame ukusuka kumathani angama-25 kuya kwangu-80, kuye ngokuthi isu lokuhlanganisa liyini.
Izindleko ziyahlukahluka kuye ngesifunda, intengo yensimbi, kanye nohlobo lwe-node. Ezimakethe eziningi, izinhlelo zohlaka lwesikhala eziphelele zibiza phakathi kwama-USD 45 nama-USD 90 ngemitha yesikwele ngayinye yezakhiwo zophahla. Lolu hlu luhlanganisa amalungu ensimbi, ama-node, ukwelashwa kwendawo, kanye nokufakwa okuyisisekelo. Ama-geometri ayinkimbinkimbi noma ukuvikelwa kokugqwala okuphezulu kungandisa izindleko ngo-15% kuya ku-25%.
Ukwelashwa kwendawo kuthinta ezomnotho zomjikelezo wokuphila. Ukufakwa kwe-hot-dip kunikeza ukuvikelwa kokugqwala iminyaka engu-25 kuya kwengu-50 ezindaweni eziningi. Izinhlelo zokupenda zidinga ukulungiswa njalo kodwa zinikeza izindleko zokuqala eziphansi. Ukuhlaziywa komjikelezo wokuphila kuvame ukukhombisa ukuthi ukufakwa kwe-galvanizing kunciphisa izindleko zobunikazi eziphelele ngo-20% eminyakeni engama-30.
Izicelo kanye Nokuguquguquka Komklamo
Izakhiwo zohlaka lwesikhala zikhonza izinhlobo ezahlukene zezakhiwo. Izikhumulo zezindiza zizisebenzisela uphahla lwesiphelo ngoba zivumela amahholo angenazinsika adlule amamitha ayi-100. Izinkundla zemidlalo zithembele ohlaka lwesikhala ukuze zisekele izinhlelo zokufulela ezihlehlayo noma ezilula. Izindawo zokugcina impahla zezimboni ziyazuza ezindaweni ezicacile ezithuthukisa ukusebenza kahle kwempahla.
Abaklami bayayazisa indlela obonakala ngayo. I-geometry ephindaphindayo idala ubuhle obuphezulu obuhambisana nolimi lomklamo wanamuhla. Abaklami bangahluka ukujula, usayizi wemodyuli, kanye nokugoba ukuze bafinyelele izinhlobo ezihlukile. Amafreyimu esikhala agobile avame ukusekela ama-domes, ama-vault emiphongolweni, kanye nophahla olukhululekile.
Ukusebenza kwemvelo nakho kuholela ekusetshenzisweni. Uphahla olulula lunciphisa ikhabhoni ehlanganisiwe. Izifundo zibonisa ukuthi ozimele besikhala sensimbi abalungiselelwe kahle banganciphisa i-CO₂ ehlanganisiwe ngo-10% kuya ku-18% uma kuqhathaniswa nokwejwayelekile.uphahla lwensimbiUkuphinda kusetshenziswe kuthuthukisa kakhulu iziqinisekiso zokusimama, njengoba insimbi yokwakha igcina amazinga okutakula angaphezu kuka-90% emhlabeni jikelele.
Amathuluzi okuklama edijithali athuthukisa ukunemba. I-BIM kanye nokumodela kwe-parametric kuvumela ukulungiswa okusheshayo kobukhulu bamalungu kanye namandla ama-node. Onjiniyela banganciphisa ukusetshenziswa kwezinto ngenkathi begcina imingcele yokuphepha. Le ndlela ifinyeza imijikelezo yokuklama futhi yehlisa ingozi yephrojekthi.
Izakhiwo zohlaka lwesikhala zihlanganisa ukusebenza kahle kwesakhiwo, ukuguquguquka kwezakhiwo, kanye nokusebenza kwezomnotho. Amandla azo okuhlanganisa izindawo ezinkulu ngezinto ezincane azenza zilungele ingqalasizinda yesimanje kanye nezakhiwo zezimboni. Njengoba umklamo wedijithali kanye nokwakhiwa kwawo kuqhubeka nokuthuthuka, ohlaka lwesikhala luzohlala luyisisombululo esiyinhloko sokwakhiwa kwesikhathi eside emhlabeni jikelele.
