Ulwakhiwo lweNsimbi lwe-ASTM A283 | Izisombululo zokwakha ezinamandla aphezulu, ezihlala ixesha elide kunye neendleko eziphantsi
Ulwakhiwo lweSakhelo seTruss yeNsimbi seSakhiwo seModular Isakhelo setruss yentsimbi luhlobo lwenkqubo yolwakhiwo apho amalungu entsimbi adityaniswe khona ngendlela yeeyunithi ezinxantathu ngokulandelelana okuthile ukwenza isakhelo esiqinileyo esinokusetyenziselwa ukuxhasa imithwalo esetyenzisiweyo. Imilo enxantathu ikhulisa amandla kunye nozinzo ngezinto ezincinci kwaye ifanelekile ixesha elide kunye negumbi elivulekileyo.
Iimpawu ezibalaseleyo
Umlinganiselo Ophezulu Wokuqina-ukuya-Kubunzima -- Ijiyometri yetruss enxantathu ivumela amandla okuthwala umthwalo aqinileyo ngentsimbi encinci.
I-Wide Clear Span - Igubungela indawo ebanzi engenazo iikholamu zangaphakathi.
Uyilo oluneenjongo ezininzi - Lulungele iindawo zokugcina impahla, iiworkshop, izityalo zokuvelisa kunye neeholo kunye neeholo zemidlalo.
Ukwenziwa kwangaphambili kunye nokuhlanganiswa ngokukhawuleza - Iinxalenye zentsimbi zinqunyulwa kwangaphambili kwaye zenziwe ngaphandle kwendawo kwaye zibotshelelwe ngokukhawuleza kwindawo.
Ubude bexesha elide – Xa kusetyenziswa ngokufanelekileyo ukhuseleko lokugqwala (ukugalela i-galvanizing, ukupeyinta, okanye ukugquma), isakhiwo sentsimbi siya kuhlala ixesha elide kangangeminyaka emininzi.

Ukwaleka okutyebileyo kwe-Epoxy Zinc
Iphakheji:
Ezi mveliso zikhuselekile kakuhle xa zipakishwa ukuze zigcine umphezulu wazo kunye nesakhiwo sazo sicocekile ngexesha lokuphathwa. Ezi nxalenye zihlala zipakishwa ngezinto ezingangeni manzi ezifana neplastiki okanye iphepha elingangeni mhlwa kwaye izixhobo ezincinci zipakishwa ngebhokisi yomthi. Ukongeza, zonke iintambo/iinxalenye ziphawulwe ngokucacileyo ukuqinisekisa ukukhutshwa kwezinto ngokukhuselekileyo kunye nokufakelwa kobuchwephesha kwindawo leyo.
Uthutho:
Izakhiwo zentsimbi zingathunyelwa ngesikhongozeli okanye ngomthwalo omkhulu ngokwesayizi nendawo eziya kuyo. Izinto ezinkulu okanye ezinzima nazo zibotshelelwa ngokuqinileyo ngeentambo zentsimbi ezineentambo zomthi kumacala omabini ukuze zikhuseleke kabini ngexesha lokuthuthwa. Zonke iinkqubo zothutho zenziwa ngokwemigangatho yothutho yamazwe ngamazwe, nokuba ngumgama omde naphesheya kwezilwandle, ukuqinisekisa ukuba iimveliso zihanjiswa ngexesha elifanelekileyo nangokhuseleko.
1. Yintoni intsimbi ye-ASTM A283?
I-ASTM A283 yintsimbi yekhabhoni ephantsi/ephakathi esetyenziswa kakhulu kwizakhiwo ezifuna ukwakheka okuhle kunye nokudityaniswa. Ifumaneka kwiBanga A, B, C, D kwaye amandla okutsalwa ayanda ukusuka kwiBanga A ukuya kwi-D.
Ibanga A - Amandla okuxinana angaphantsi kakhulu, ubukhulu becala aguquguquka kakhulu
Ibanga B kunye no-C – Amandla aPhakathi kunye nokuQhubeka
Ibanga D - Amandla Okuxinana Aphezulu KwamaBanga e-A283
2. Ziziphi iindlela eziqhelekileyo zokusetyenziswa kwezakhiwo zentsimbi ze-ASTM A283?
Izicelo eziqhelekileyo ze-A283 ziquka iifreyimu ezikhaphukhaphu neziphakathi: ezifana
Izakhiwo zemizi-mveliso nezeendawo zokugcina impahla, iibhulorho kunye namaqonga, kunye nezinye izinto ezisetyenziswa lula kwezorhwebo, ngoku zingakhiwa nge-aluminium, ngenxa yamandla ayo aphezulu kunye neempawu zayo zokumelana nokugqwala.
Izixhobo zentsimbi ezenziwe ngobunjineli ezifana neegirders, imiqadi, kunye neekholamu
Amanqanaba entsimbi ukuze kubekho amandla aphakathi, ukuthungwa kakuhle kweepleyiti kunye neephaneli zesakhiwo
3. Ifumaneka ngeziphi iimilo kunye nobukhulu be-ASTM A283?
Iipleyiti – zihlala zinobukhulu obuyi-6–200 mm
Amaphepha – Icandelo elincinci leephaneli zesakhiwo
Iikhoyili - ngamanye amaxesha ukuze ziqhubeke nokusetyenzwa
4. Iyintoni i-ASTM A283 enokudityaniswa?
Ukudityaniswa kakuhle kakhulu - i-MIG, i-TIG kunye nokudityaniswa kwe-stick welding zezona zilungileyo.
Iipleyiti ezincinci (<25 mm) azidingi ukufudunyezwa kwangaphambili.
Ukuthintela ukuqhekeka xa kudityaniswa iindawo ezixineneyo, kucetyiswa ukuba kusetyenziswe iinkqubo zokudityaniswa ezingenahydrogen eninzi.
6. Ngaba i-A283 ingafakwa i-galvanish okanye ipeyintwe?
Ewe. Umphezulu wentsimbi unokuba:
I-hot-dip galvanizing – isetyenziswa kakhulu ekukhuseleni umhlwa
Ukupeyinta okanye ukugquma ngomgubo – kuthandwa kakhulu xa kusakhiwa iifacade kunye nezakhiwo zoshishino
