Iqonga leNyathelo loLondolozo kwiProfayili yeAluminiyam lifanele liyilwe njani ukuze lithwale umthwalo?

Ukuyila iqonga lenyathelo lokulungisa kwiprofayili ye-aluminiyam akubandakanyi ukukhetha iprofayili enzima ngokwaneleyo kodwa kumalunga nokuthwala imithwalo evela ebantwini, izixhobo kunye nezixhobo zokulungisa endleleni - umqadi, imiqadi, izithuba, uqhagamshelo - ngelixa ujonga amandla kunye nokuphambuka kwinqanaba ngalinye.I-Chengdu E&I Aluminium Industry Co., Ltd.Usebenze kwiiprofayili ze-aluminium zoshishino kunye neenkqubo zefreyimu kangangeminyaka eli-15, ugcina iimodeli zeprofayili ezingaphezu kwe-100 kunye neetoni ezingamakhulu aliqela kwisitokhwe, kwaye uphatha uyilo, umatshini ochanekileyo kunye nokuhlanganiswa kwangaphambili kwamaqonga ezinyathelo ezivela kwimizobo yabathengi. Amacandelo angezantsi alandela ulandelelwano loyilo.

1. Uyilo lomthwalo weqonga lokugcina i-aluminiyam luqala ngemithwalo

Indawo yokuqala kukuchaza imithwalo ngokucacileyo, kungekhona ukukhetha icandelo. Uphoswe ngumthwalo kwaye akukho sibalo sokubala ezantsi siya kuhlala ixesha elide.

Dwelisa iindidi ezintathu zomthwalo ngokwahlukeneyo

• Umthwalo wabasebenzi ophilayo: ukuma, ukuhamba nokunyuka ngexesha lokulungiswa, apho imithwalo esasazekileyo nexineneyo iyenzeka kunye.
• Izixhobo kunye nezixhobo ezingasetyenziswanga: iingxowa zezixhobo kunye nezinto ezisusiweyo, ezihlala zifika njengomthwalo oxineneyo phakathi kobubanzi.
• Umthwalo wezixhobo: apho iqonga lisebenza njengedekhi yenkonzo, iipompo kunye neemoto zidweliswe ngokwahlukeneyo ngokobunzima bazo bokwenyani kwaye azifakwanga kumthwalo wabasebenzi.

Izinto ezitshintshayo kunye nokudibanisa umthwalo

Umsebenzi wokulungisa uzisa impembelelo yokuma kweenyawo kunye nokutshintsha ubunzima, ngoko ke kukho into eguqukayo esebenza phezu kwemithwalo engashukumiyo; apho imithwalo emininzi isebenza ngaxeshanye, kusebenza amaxabiso adibeneyo. Thatha amaxabiso akwimigangatho elawula iprojekthi (uthotho lwe-EN ISO 14122 okanye i-OSHA 1910.23, umzekelo) kwaye ubhale isiseko kwiphepha lokubala.

2. Umphezulu wokunyathela: iinkcukacha zepleyiti kunye nesithuba senkxaso zibeka ukuqina kokuqala

Indlela yokuthwala umthwalo iqala apho. Ipleyiti yokukhangela eyenziwe nge-aluminiyam yeyona ikhethwayo; ubukhulu bepleyiti kunye nokuqina kwayo kugqiba ukuba ithatha umgama ongakanani ngaphandle kokujika okubonakalayo, kwaye ubude bepleyiti bufuna ipleyiti etyebileyo okanye inkxaso exineneyo.

Umgama phakathi kwepleyiti yokunyathela kunye neebhari ubalulekile ngokufanayo: umgama othe qelelene kakhulu unika isandi esingenanto kunye nokuntywila phantsi kweenyawo, ngelixa umgama osondeleyo uvumela ukuba i-tread idlule ngokulinganayo kwiibhari.

3. Imiqadi kunye neenkxaso: i-span iqhuba ukuphambuka okungaphezulu kobukhulu becandelo

Imiqadi ithwala iqonga, kwaye utshintsho kwisithuba luchaphazela ukuphambuka okungaphezulu kakhulu kunotshintsho kwisigaba.

• Ispan enye okanye i-multi-span: inkxaso ephakathi inqumla ububanzi besithuba, kwaye ukuphambuka kuwa kunye netyhubhu yesithuba — kudla ngokuba luncedo ngakumbi kunokunyusa ubungakanani besithuba.
• Imiqadi emibini okanye umqadi omnye: amaqonga abanzi asebenzisa imiqadi emibini ukuze umbindi wendlela yokunyathela ungashiywa ungaxhaswanga.
• Ulawulo lokuphambuka: kwiqonga lokulungisa, ukuphambuka kudla ngokufikelela kumda walo ngaphambi kokuba amandla enze njalo, ngoko ke zombini kufuneka zidlule.

Ixesha lokungakhathali kunye ne-section modulus zivela kwiphepha ledatha yobugcisa. Amaxabiso ahluka kakhulu kuthotho lwe-90, 80 kunye ne-40, ngoko ke inombolo yothotho yodwa ayikuxeleli nto ingako.

4. Iipali, izixhobo zokuxhasa kunye nokuzinza ecaleni

Ngaphaya komthwalo othe nkqo, iqonga kufuneka lixhathise ukushukuma ecaleni.

Iinyawo ezilinganayo ezantsi kwepali nganye zithatha ukungalungelelani komgangatho; amaqonga amade afumana i-diagonal bracing, okanye i-tie back to the frame kwisakhelo sesixhobo, ukuze kuthintelwe intshukumo xa umntu enyathela. Kwii-post-to-beam connections, i-end-face connectors zinika i-node eqinileyo kune-engile brackets ezifakwe ngaphandle.

5. Uqhagamshelo: apho indlela yomthwalo yenziwa okanye ilahlekile

Iikhonkco zezona zibuthathaka kwikhonkco. Ii-engile brackets ezibotshelelwe ngaphandle zinomthamo omncinci; ii-bolts ezishiywe ngaphantsi kwe-torque, okanye ii-burrs kunye nee-chips ezishiywe ebusweni bokudibana, aziwuthatheli ngqalelo umthamo obaliweyo.

6. Izikhuselo, iibhodi zeenzwane kunye nokukhusela ukuwa ziyinxalenye yoyilo

Izixhobo zokhuseleko zifaneleke kwinqanaba loyilo kunokuba zibe kuluhlu lokongeza: ukuphakama kwereli kunye nendawo yereli kulandela umgangatho olawulayo, iibhodi zeenzwane zigcina izixhobo zingawi, kwaye iindawo ezivulekileyo zifumana isango okanye ityathanga elizivalela ngokwalo.

Iipali zomqadi wendlela kufuneka ziwele phezu kweepali okanye kwiipali, kungekhona kwipleyiti yokunyathela kuphela — umqadi wendlela wenzelwe ukuhamba ngeenyawo, kungekhona umthwalo osecaleni othwalwa ngumqadi wendlela.

7. Iingeniso zoyilo: qinisekisa izinto ezintandathu kuqala

Ukujonga umthwalo kulungile kuphela xa ufake izinto ezifunekayo. Qinisekisa ezi zintandathu ngaphambi kokuba umsebenzi uqale, kwaye ubalo kunye nemizobo zifika kanye ngexesha lokuqala.

1. Ukuphakama kokusebenza: ubude obucacileyo ukusuka kumgangatho ukuya kumphezulu weqonga, nto leyo ebeka uyilo lweposti kunye ne-bracing.
2. Ubungakanani beplatifomu: ubude, ububanzi kunye nayo nayiphi na imvulophu yezixhobo ekufuneka ithintelwe.
3. Indawo yokuvula: licala bangena kulo abantu baze baphume kulo, nokuba isango elizivalelayo liyafuneka na.
4. Icala lokufikelela: apho abasebenzi bolondolozo basondela khona, kwaye zeziphi iikona ezihlala zivulekile kwindawo yokukhusela.
5. Indlela yokufikelela: amanyathelo azinzileyo, ileli ehambayo, okanye uqhagamshelo kwiqonga elikhoyo.
6. Imeko yomgangatho: ukuthamba kunye nezinto eziphathekayo, ezigqiba ekubeni iinyawo zokulinganisa okanye ii-ankile zeekhemikhali ziyafuneka na.

Ngezinto ezifakwayo esandleni, icandelo kunye noyilo lwenkxaso yeqonga le-aluminiyam zinokulungiswa ngexesha elinye, endaweni yokuba ziphinde zisetyenziswe emva kokuba imizobo iphumile.

8. Imibuzo Ebuzwa Rhoqo

Iqonga lenyathelo lokulungisa kwiprofayili ye-aluminiyam lijongwa inqanaba ngenqanaba — imithwalo, ukunyathela, imiqadi, uqhagamshelo, izixhobo zokhuseleko — kwaye ukugcina olo landelelwano yikona okwenza iziphumo zime. Ukuze ufumane uhlolo lomthwalo, uphuhliso lomzobo kunye nobonelelo olupheleleyo lweqonga, nxibelelana neqela lethu lobuchwephesha ngokusebenzisa i-w.
