Kapangidwe ka Chitsulo cha ASTM A913 | Chitsulo cha H-Beam champhamvu kwambiri cha nyumba zamafakitale ndi zamalonda
Kapangidwe ka Chimango cha Chitsulo cha Chitsulo cha Nyumba Yokhazikika Chimango cha chimango chachitsulo ndi mtundu wa dongosolo la kapangidwe kake momwe ziwalo zachitsulo zimalumikizidwa pamodzi mu mawonekedwe a mayunitsi amakona atatu mu ndondomeko inayake kuti apange chimango cholimba chomwe chingagwiritsidwe ntchito kuthandizira katundu wogwiritsidwa ntchito. Mawonekedwe amakona atatu amawonjezera mphamvu ndi kukhazikika ndi zinthu zochepa ndipo ndi oyenera nthawi yayitali komanso malo otseguka.
Zinthu Zapadera
Chiŵerengero Champhamvu Kwambiri-Kulemera -- Maonekedwe a truss a triangular amalola mphamvu yonyamula katundu wamphamvu ndi chitsulo chochepa.
Chigawo Chowonekera Kwambiri - Chimaphimba malo ambiri opanda mizati yamkati.
Kapangidwe ka zinthu zosiyanasiyana - Kabwino kwambiri m'nyumba zosungiramo zinthu, m'mashopu ochitira misonkhano, m'mafakitale opangira zinthu komanso m'maholo ochitira misonkhano ndi m'maholo amasewera.
Kukonzekera ndi Kumanga Mwachangu - Zitsulo zimadulidwa kale ndikupangidwa kunja kwa malo ndipo zimalumikizidwa mwachangu pamalopo.
Kutalika Kwa Nthawi - Ngati chitsulocho chikugwiritsidwa ntchito mokwanira poteteza dzimbiri (kupopera, kupaka utoto, kapena kuphimba), chimangocho chidzakhala ndi moyo wautali kwa zaka zambiri.
Zigawo
Chord Yapamwamba: Chiwalo chapamwamba chopingasa kapena chotsetsereka cha truss
Chord Yapansi: Chiwalo chopingasa cha pansi chili ndi mphamvu
Mamembala a pa intaneti: Zinthu zopingasa ndi zoyimirira zomwe zimapanga gawo la triangular
Malumikizidwe: Mizere yolumikizidwa ndi mabolt kapena welded yomwe imalumikiza ziwalo
Kulimbitsa (Mwasankha): Kukhazikika kwapadera kwa mbali kuti zikhale zazikulu

1. Thandizo la Nthambi ya Kunja ndi Chilankhulo cha Chisipanishi
Tili ndi maofesi akunja okhala ndi anthu olankhula Chisipanishi ndipo timatha kulankhula zilankhulo ziwiri ndi makasitomala athu ochokera ku Latin America ndi Europe.
Gulu lathu limasintha malamulo okhudza kuchotsera katundu, zikalata, ndi kutumiza katundu kunja kuti lithandize kutumiza katundu pa nthawi yake komanso kufulumizitsa kukonza katundu wotumizidwa kunja.
2. Katundu Wokonzeka Kutumizidwa Mwachangu
Timasunga zinthu zokwanira zopangira zitsulo zotentha monga H beam, I beam ndi zitsulo.
Izi zikutanthauza nthawi yofulumira yopezera makasitomala kuti apeze chinthu chomwe angadalire, mwachangu, pantchito zadzidzidzi.
3. Katswiri Wopanga Ma Packaging
Zogulitsa zonse zili ndi ma CD oyenera kuyenda panyanja (kulumikiza chimango chachitsulo, kukulunga kosalowa madzi, chitetezo cha m'mphepete).
Izi zitsimikizira ndikuonetsetsa kuti katunduyo ali otetezeka, palibe kuyenda kulikonse panthawi yoyenda mtunda wautali komanso palibe kuwonongeka kulikonse mukafika padoko lopitako.
4. Kutumiza ndi Kutumiza Moyenera
Timagwira ntchito ndi otumiza katundu odalirika adziko lonse ndipo titha kupereka njira zotumizira zinthu mosinthasintha: FOB, CIF, DDP.
panyanja, pa sitima, pamsewu, tikukulonjezani kutumiza katundu panthawi yake komanso ntchito yolondola yogwirira ntchito.
Chithandizo pa chiwonetsero cha pamwamba: Chophimba cha epoxy zinc cholemera, Chopangidwa ndi Galvanized (makulidwe a galvanized layer ≥85μm amatha kufikira zaka 15-20), chopaka mafuta akuda, ndi zina zotero.
Wopaka Mafuta Wakuda
Chitsulo chopangidwa ndi galvanized
Chophimba cholemera cha Epoxy Zinc
Phukusi:
Zinthuzi zimatetezedwa bwino mu phukusi kuti pamwamba ndi kapangidwe kake kasawonongeke pogwira ntchito. Zigawozo nthawi zambiri zimapakidwa zinthu zosalowa madzi monga filimu ya pulasitiki kapena pepala losalowa dzimbiri ndipo zowonjezera zazing'ono zimapakidwa bokosi lamatabwa. Kuphatikiza apo, zingwe/zigawo zonse zimalembedwa bwino kuti zitsimikizire kuti kutsitsa zinthuzo kutetezedwa komanso kuyikidwa mwaluso pamalopo.
Mayendedwe:
Nyumba zachitsulo zitha kutumizidwa ndi chidebe kapena chonyamulira katundu molingana ndi kukula ndi komwe zikupita. Zinthu zazikulu kapena zolemera zimamangiriridwanso mwamphamvu ndi zingwe zachitsulo zokhala ndi zingwe zamatabwa mbali zonse ziwiri kuti zitetezedwe kawiri panthawi yoyendera. Njira zonse zoyendetsera zinthu zimachitika molingana ndi muyezo wapadziko lonse lapansi woyendera, ngakhale mtunda wautali komanso kunja kwa dziko, kuti zitsimikizire kuti zinthuzo zatumizidwa pa nthawi yake komanso motetezeka.
1. Ndi magiredi ati omwe alipo a ASTM A913?
Magiredi wamba ndi awa:
ASTM A913 Giredi 50

Magiredi apamwamba amatanthauza mphamvu yochuluka yobereka komanso mphamvu yabwino yonyamula katundu.
2. Kodi ubwino waukulu wa kapangidwe ka chitsulo cha ASTM A913 ndi uti?
Mphamvu yayikulu yokhala ndi kulemera kochepa kwachitsulo
Kugwira ntchito bwino komanso kugwira ntchito mozungulira kwa zivomerezi
Kutha kusungunula bwino kwambiri popanda kutentha nthawi zambiri
Katundu wokhazikika wamakina
Mtengo wotsika wa maziko ndi mayendedwe chifukwa cha kapangidwe kopepuka
3. Kodi kapangidwe ka chitsulo ka ASTM A913 kamagwiritsidwa ntchito kuti nthawi zambiri?
Nyumba zamafakitale: mafakitale, malo ogwirira ntchito, zomera
Malo osungiramo katundu ndi malo osungiramo katundu
Nyumba zamalonda ndi malo owonetsera zinthu
Mapulojekiti a zomangamanga ndi malo ogwirira ntchito za anthu onse
Nyumba zachitsulo zazikulu komanso zazitali
4. Kodi ASTM A913 ndi yoyenera madera okhala ndi zivomerezi?
Inde. ASTM A913 ili ndi kulimba komanso kusinthasintha kwabwino, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito popanga zitsulo zosagwedezeka ndi zivomerezi, makamaka m'madera omwe chivomerezi chimagwedezeka monga Central America, South America, ndi madera ena a Asia.
5. Kodi ASTM A913 ikufanana bwanji ndi ASTM A992?
ASTM A913 nthawi zambiri imakhala ndi mphamvu zokolola zambiri komanso kulimba bwino kuposa ASTM A992. Imalola magawo opepuka kuti agwire ntchito yofanana, kuchepetsa kugwiritsa ntchito chitsulo pamene ikusunga chitetezo cha kapangidwe kake.
6. Kodi ASTM A913 ingalumikizidwe mosavuta?
Inde. ASTM A913 ili ndi mpweya wofanana ndi mpweya wotsika, zomwe zimapangitsa kuti ikhale yogwirizana bwino. Nthawi zambiri, sipamafunika kutentha koyambirira, ndipo njira zoyeretsera za AWS zingagwiritsidwe ntchito.
7. Ndi mankhwala otani omwe alipo pamwamba?
Gulani utoto wa primer
Dongosolo lophimba la epoxy kapena PU
Kuviika m'madzi otentha
Chophimba choletsa dzimbiri chokhala ndi zigawo zambiri m'madera a m'nyanja kapena m'madera otentha
8. Kodi kapangidwe ka chitsulo ka ASTM A913 kangasinthidwe?
Inde. Kutalika, kutalika, kapangidwe kake, kapangidwe ka katundu, utoto, ndi njira zolumikizira zonse zitha kusinthidwa kutengera zojambula za polojekiti ndi ma code a kapangidwe kake.
