ASTM A283 Chimiro Chesimbi | Mhinduro dzekuvaka dzakasimba, dzinogara kwenguva refu uye dzinoshanda zvakanaka
Chimiro cheSimbi yeTruss yeChivako cheModular Furemu yesimbi yetruss rudzi rwechimiro umo nhengo dzesimbi dzakabatana pamwe chete muchimiro chemayuniti matatu nenzira yakatarwa kuti dzigadzire furemu yakasimba inogona kushandiswa kutsigira mitoro inoshandiswa. Chimiro chetatu chinowedzera simba nekugadzikana nezvinhu zvishoma uye chakakodzera kureba kwenguva refu uye nzvimbo yakavhurika.
Zvinhu Zvinoshamisa
Simba Rakakura-Kusvika-Kurema -- Maitiro ekutakura zvinhu zvematatu anogonesa kutakura zvinhu zvakasimba nesimbi shoma.
Hurefu Hwakajeka - Hunofukidza nzvimbo yakakura isina makoramu emukati.
Dhizaini yemabasa akasiyana-siyana - Yakanakira matura, maworkshop, mafekitori ekugadzira uye kumaauditoriums nemahoro emitambo.
Kugadzira & Kukurumidza Kubatanidza - Zvikamu zvesimbi zvinochekwa-chekwa uye zvinogadzirwa panzvimbo yacho uye zvinokurumidzirwa kusungirirwa panzvimbo yacho.
Kugara Kwenguva Refu - Kana simbi ikashanda zvakanaka kudzivirira ngura (kushongedza, kupenda, kana kuputira), chivakwa chesimbi chicharamba chichishanda kwemakumi emakore.
Zvikamu
Chord Yepamusoro: Nhengo yepamusoro yakatsetseka kana yakatsetseka yetruss

1. Rutsigiro rweBazi reMhiri kweMadokero neMutauro wechiSpanish
Tine mahofisi ekune dzimwe nyika ane vashandi vanotaura chiSpanish uye tinokwanisa kutaura mitauro miviri nevatengi vedu vanobva kuLatin America neEurope.
Chikwata chedu chinogadzirisa zvinodiwa pakubviswa kwezviteshi zvemutero, magwaro, uye kutumira kunze kwenyika kuti zviite kuti zvinhu zvisvike panguva yakakodzera uye kukurumidzise kugadziriswa kwezvinhu zvinopinzwa munyika.
2. Yagadzirira Kutumira Nekukurumidza
Tine zvinhu zvakakwana zvesimbi yakaputirwa yakagadzirwa nesimbi zvakaita seH beam, I beam uye simbi yakagadzirwa nesimbi.
Izvi zvinoreva nguva dzinokurumidza dzekuwana vatengi kuti vawane chigadzirwa chavanovimba nacho, nekukurumidza, pamabasa iwayo ekukurumidza.
3. Kurongedza Kwehunyanzvi
Zvigadzirwa zvese zvakazara nekurongedza kwakajairika kwegungwa (kusungirirwa kwesimbi, kuputira kusingapindi mvura, dziviriro yemipendero).
Izvi zvichavimbisa uye zvichave nechokwadi chekuti kurodha kwakachengeteka, hapana kufamba panguva yekufambisa kure uye hapana kukuvara kana yasvika pachiteshi chekuenda.
4. Kutumira & Kuendesa Zvinobudirira
Tinoshanda nevatengi venyika vakavimbika uye tinogona kupa mitemo yekutumira inochinjika: FOB, CIF, DDP.
negungwa, njanji, mugwagwa, tinokuvimbisai kutumira zvinhu nenguva uye sevhisi yekutevera zvinhu inoshanda.
Kurapa pamusoro pechiratidziro: Epoxy zinc-rich coating, Yakabatidzwa (hurefu hwebasa rekupisa hunogona kusvika makore 15-20), yakazorwa mafuta matema, nezvimwewo.

Yakagadzikwa
Kuputira kwakapfuma muEpoxy Zinc
Pasuru:
Zvigadzirwa izvi zvakachengetedzwa zvakanaka mumapakeji kuti zvirambe zvisina kukuvadzwa pamusoro pazvo uye chimiro chazvo panguva yekubata. Zvikamu zvacho zvinowanzoiswa zvinhu zvisingapindi mvura zvakaita sepurasitiki kana bepa rinodzivirira ngura uye zvishandiso zvidiki zvinoiswa mumabhokisi emapuranga. Pamusoro pezvo, tambo/zvikamu zvese zvinoratidzwa zvakajeka kuti zvive nechokwadi chekuti zvinoburitswa zvakachengeteka uye kuti zvinoiswa nehunyanzvi panzvimbo yacho.
Kutakura:
Zvivakwa zvesimbi zvinogona kutumirwa nemudziyo kana kutakura zvinhu zvakawanda zvichienderana nehukuru nenzvimbo yazvinenge zvichiendeswa. Zvinhu zvikuru kana zvinorema zvinosungirirwawo zvakasimba netambo dzesimbi dzine matanda kumativi ese kuti zvidzivirire kaviri panguva yekufambisa. Maitiro ese ekufambisa zvinhu anoitwa zvichienderana nemutemo wekufambisa wepasi rose, kunyangwe daro refu uye mhiri kwemakungwa, kuve nechokwadi chekuti zvigadzirwa zvinotumirwa nenguva uye zvakachengeteka.
1. Chii chinonzi ASTM A283 simbi?
ASTM A283 isimbi yekabhoni yakaderera/yepakati inoshandiswa zvakanyanya mukushandiswa kwemaumbirwo ayo anoda kuumbwa zvakanaka uye kuchinjika. Inowanikwa muGiredhi A, B, C, D uye simba rekudhonza riri kuwedzera kubva kuGiredhi A kusvika kuD.
Giredhi A - Simba rekudhonza zvishoma rinoita kuti ductility iwedzere
Giredhi B & C - Simba Rine Mwero uye Ductility
Giredhi D - Simba reKusimba repamusoro reMagiredhi eA283
2. Ndezvipi zvinoshandiswa pakugadzira simbi dzeASTM A283?
Mashandisirwo akajairika eA283 anosanganisira mafuremu akareruka-epakati: akadai se
Zvivako zvemaindasitiri nedzimba dzekuchengetera zvinhu, mabhiriji nemapuratifomu, nezvimwe zvinoshandiswa mukutengeserana, zvino zvinogona kuvakwa nearuminiyamu, nekuda kwesimba rayo guru uye hunhu hwayo hwekudzivirira ngura.
Zvikamu zvesimbi zvakagadzirwa neinjiniya zvakaita semagirders, matanda, uye makoramu
Magiredhi esimbi ekusimbisa zvine mwero, mapuratifomu nemapaneru anogona kusungirirwa zvakanaka
3. ASTM A283 inowanikwa mumhando dzipi uye saizi dzipi?
Maplates - ane ukobvu hwe6–200 mm nguva dzose
Mapepa - Chikamu chakatetepa chemapaneru ekuvaka
Makoiri - dzimwe nguva kuti ashandiswe zvakare
4. Chii chinonzi ASTM A283 weldability?
Kugona kupinza zvakanaka - MIG, TIG uye kupinza zvimiti ndizvo zvakanakisisa.
Maplate matete (<25 mm) haawanzodi kudziiswa.
Kuti pasave nekutsemuka pakusanganisa zvikamu zvakakora, zvinokurudzirwa kushandisa nzira dzekubatanidza dzisina hydrogen yakawanda.
6. Ko A283 inogona kupendwa negaravhiti here kana kuti nependi?
Ehe. Pamusoro pesimbi panogona kuva:
Kupisa-kunyika - kunonyanya kushandiswa kudzivirira ngura
Kupenda kana kuputira hupfu - kwakakurumbira kushandiswa mukuvaka mafacade nezvivakwa zvemaindasitiri
