Isikhokelo soBukhulu be-RHS obuDumileyo kuLwakhiwo kunye nokuFakelwa

Xa ungena kwindawo yokwakha okanye kwivenkile yentsimbi yasekuhlaleni, uya kuphawula ukuba nangona kukho amakhulu eeprofayili zentsimbi ezinokwenzeka, kukho ezimbalwaIcandelo eliyingxande eliyiHole (I-RHS)ubukhulu benza umsebenzi onzima. Ezi azizo nje iimilinganiselo ezingacwangciswanga; ziindawo ezintle zobunjineli—ezibonelela ngokulinganisela okubalaseleyo kobunzima, ixabiso, kunye namandla.

Ukuba uceba ukwakha okanye ukufumana izixhobo, nantsi ingqwalasela yobukhulu be-RHS oza kudibana nayo kunye nendlela ezisebenza ngayo kwihlabathi lokwenyani.

Ubungakanani "bemihla ngemihla": 80×40mm kunye ne-100×50mm

Ukuba bekukho useto "oluqhelekileyo" lweefreyimu zentsimbi, ibiya kuba yile. Kwiindawo ezininzi zehlabathi, i-80×40 kunye ne-100×50 zezona zinto zokuqala umthengisi azenzayo kwirakhi kuba zisingatha uninzi lwemisebenzi yolwakhiwo olukhanyayo ukuya koluphakathi.

I-80×40mm isebenza:Cinga ngexesha lokugqibela ubona ucingo lwesinyithi lwanamhlanje, isango lepaki, okanye i-racking yangaphakathi kwiveni yokuhambisa impahla. Olu bukhulu ludumile kuba kulula ukuluphatha—umenzi omnye unokuhambisa ubude beemitha ezi-6 ngaphandle kokufuna i-crane, nto leyo eyenza ukuba ifaneleke kakhuluamasango okuhlala, iitreyila ezilula, kunye nee-handrails ze-mezzanine.

Utshintsho lwe-100×50mm:Xa usiya kwi-100×50, uhlala uthetha “ngokuthwala umthwalo” ngendlela yorhwebo. Uza kuzifumana eziiipurlinskwiindawo zokugcina impahla ezincinci okanye kwisakhelo esiphambili seiiphaneli zelangaNgenxa yokuba inzulu kabini kunobubanzi bayo, iyakwazi ukuqikelelwa ngokumangalisayo ukuba iinjineli zibalele ukuba iza kujika kangakanani xa kukho ikhephu okanye umthwalo womoya omkhulu.

IiGiants ezikhethekileyo: 200×500mm kunye ne-60×500m

Wakuba ufikelele kububanzi obuyi-500mm, awukhi nje isakhelo; wakha uphawu olubalulekileyo. Ezi sayizi zihlala "zicwangciswe ngokweprojekthi" endaweni yokuba zigcinwe njengothuli.I-200×500mm (Isiphakamisi Esinzima):Eli lirhamncwa lecandelo elithile. Uza kuzibona ezi kwiiindawo zothutho okanye izityalo ezinkulu zoshishino.Ngenxa yobukhulu bayo bangaphakathi, idla ngokusetyenziswa njenge "kholamu edibeneyo." Abakhi baya kuyimisa, bathulule ikhonkrithi enamandla aphezulu embindini, kwaye ngequbuliso ufumana ikholam enokuxhasa indawo yokugcina impahla enezitezi ezininzi ngelixa ihlala incinci xa ithelekiswa nentsika enkulu yekhonkrithi.

I-60×500mm (Ukhetho loMyili):Le yiprofayili enomtsalane nebhityileyo. Ijongeka njengephiko elikhulu lentsimbi. Uza kuyibona le nto ngaphandleIzakhiwo zeeofisi ezikumgangatho ophezulu okanye izitishi zeenqwelo-moya.Isetyenziselwa “udonga lwamakhethini.” Ubunzulu obuyi-500mm bukhona ukuze kuthintelwe udonga lweglasi ukuba lungangeni ngexesha lesiphango, kodwa ububanzi obuyi-60mm buncinci kangangokuba abuyithinteli imbonakalo yabantu abangaphakathi. Ngumtshato ogqibeleleyo “wobunzima” “nocacileyo.”

Intsimbi "Eneenkcukacha": I-RHS Encinci (umz., 40×20mm)

Ayizizo zonke izinto ezifuna ukuxhasa uphahla. Ngamanye amaxesha udinga nje umphetho ococekileyo nothe tye ongagobiyo njengomthi.

Apho ifaneleka khona:Lo ngummandla weabayili befenitshala kunye nabathengisi.Ukuba ubona ifreyimu yedesika "encinci kakhulu" kwiofisi yetekhnoloji okanye kwindawo yokureyitha impahla kwivenkile ethengisa iimpahla ezininzi, kusenokwenzeka ukuba yi-40×20mm RHS.umbhobho obhityileyo odongeni(1.6mm ukuya kwi-2.0mm), oko kuthetha ukuba kulula ukuwelda nge-welder ye-MIG eqhelekileyo kwaye igqibezela kakuhle nge-powder-coated.

Kutheni iiCandelo "eziValiweyo" ziphumelela

Umbuzo oqhelekileyo ngulo:Kutheni usebenzisa ityhubhu engunxande (RHS) endaweni ye-I-beam eqhelekileyo okanye i-aItshaneli ye-C?

Impendulo idla ngokuvela kuUkujika (Ukujika).Ukuba uthatha i-C-channel uze ubeke umthwalo onzima ecaleni, ifuna ukujika njenge-noodle. I-RHS yi-loop evaliweyo; ayithandi ukujikajika. Oku kwenza kube lula kakhulu kwizakhiwo "ezingalinganiyo", njengebalcony ene-cantilevered okanye uphawu oluphuma kwisakhiwo. Ngaphezu koko, akukho "milebe" okanye "iipokotho" zamanzi kunye nenkunkuma yeentaka ezinokuqokelelwa kuzo, nto leyo enciphisa kakhulu ukugqwala.

Inqaku "kwiphepha" (Amabanga kunye neMigangatho)

Nangona ubukhulu bubalulekile, "i-DNA" yentsimbi ibalulekile ngokufanayo. Ngokuqhelekileyo uya kuva amagama amabini aphambili:

I-S235 vs. i-S355:Cinga nge-S235 “njengomgangatho” kunye ne-S355 “njengovavanyo oluphezulu.” Ukuba wakha ishedi elula engasemva kwendlu, i-S235 ilungile. Ukuba wakha ibhulorho okanye into eza kubethwa yimimoya enamandla, khetha i-S355.

I-Galvanized vs. Black:Ukuba intsimbi iza kufihlwa eludongeni, intsimbi “emnyama” (efakwe ioyile) ibiza kancinci. Ukuba iphuma ngaphandle, uyifuna “iHot-Dip Galvanized.” Iya kujongeka njengesilivere kwaye inamabala amancinci, kodwa ayiyi kugqwala kangangeminyaka engamashumi amathathu.
