Rondedzera Chinangwa uye Zvinodiwa
PakusarudzaU-chiteshi simbi, basa rekutanga nderekujekesa mashandisiro ayo chaiwo uye zvakakosha zvinodiwa:
Izvi zvinosanganisira kuverengera nemazvo kana kuongorora mutoro wepamusoro waunoda kutsungirira (static load, dynamic load, impact, etc.), iyo inotaridza zvakananga zvakatemwa uye zviyero (urefu, upamhi hwemakumbo, chiuno chakakora) uye giredhi resimba rezvinhu; kunzwisisa mamiriro ayo ekushandisa (zvakadai sekuvaka matanda / purlins, mechanical frames, conveyor line inotsigira, masherufu kana kushongedzwa), mamiriro akasiyana ane kusimbiswa kwakasiyana pamusoro pesimba, kusimba, kunyatsojeka uye chitarisiko; tichifunga nezvekushandiswa kwezvakatipoteredza (mukati/kunze, ingave yakanyorova, corrosion media), iyo inosarudza anti-corrosion zvinodiwa (sekupisa-dip galvanizing, kupenda) kana kuti mamiriro ekunze esimbi / simbi isina tsvina inodiwa; kujekesa nzira yekubatanidza (welding kana bolting), iyo ichakanganisa dhizaini yegumbo (flat welding surface kana maburi akachengetwa anodiwa) uye zvinodiwa zvezvinhu weldability; panguva imwecheteyo, zvinodikanwa kusimbisa zvirambidzo zvehukuru hwenzvimbo yekuisa (kureba, kureba, hupamhi) uye yakatarwa mirau kana indasitiri zviyero izvo purojekiti inofanirwa kutevedzera kuti ive nechokwadi chekuti zvinhu zvakasarudzwa zvinosangana nekuchengetedza uye kushanda zvinodiwa.
U Channel Simbi Zvinotsanangurwa, Dimensions uye Zvishandiso
1. Zvinotsanangurwa
European standardUPN chiteshimhando dzakatumidzwa zita rehurefu hwavo hwechiuno (yuniti: mm). Ivo vane U-yakaumbwa muchinjiko-chikamu uye akakosha paramita anosanganisira:
Kureba kwechiuno (H): Hurefu hwese hwechiteshi. Semuenzaniso, urefu hwechiuno cheUPN240 ndeye 240 mm.
Band width (B): Upamhi hweflange. Semuenzaniso, iyo UPN240 ine 85 mm bhendi.
Ukobvu hwechiuno (d): Kukora kwedandemutande. Semuenzaniso, iyo UPN240 ine chiuno chakakora che9.5 mm.
Band ukobvu (t): The flange ukobvu. Semuenzaniso, iyo UPN240 ine bhendi ukobvu hwe13 mm.
Theoretical huremu pamamita: Huremu pahurefu hwechikamu (kg/m). Semuenzaniso, iyo UPN240 ine huremu hwe33.2 kg/m.
Zvakajairwa Zvinodiwa (Partial Models):
| model | Kureba kwechiuno (mm) | Kufara kwegumbo (mm) | Ukobvu hwechiuno (mm) | Kukora kwegumbo (mm) | Theoretical huremu pamamita (kg/m) |
| UPN80 | 80 | 45 | 6 | 8 | 8.64 |
| UPN100 | 100 | 50 | 6 | 8.5 | 10.6 |
| UPN120 | 120 | 55 | 7 | 9 | 13.4 |
| UPN200 | 200 | 75 | 8.5 | 11.5 | 25.3 |
| UPN240 | 240 | 85 | 9.5 | 13 | 33.2 |
| UPN300 | 300 | 100 | 10 | 16 | 46.2 |
| UPN350 | 350 | 100 | 14 | 16 | 60.5 |
2. Rudzi rwezvinhu
UPN chiteshi chesimbi zvinhu zvinofanirwa kusangana neEuropean standard EN 10025-2. Sarudzo dzakajairika dzinosanganisira:
(1) Zvinhu zvakajairika
S235JR: Goho simba ≥ 235MPa, mutengo wakaderera, wakakodzera kune static zvimiro (zvakadai sezvitsigiro zvemwenje).
S275JR: Goho simba ≥ 275MPa, yakaenzana simba uye hupfumi, inoshandiswa kune akajairwa ekuvaka mafuremu.
S355JR: Goho simba ≥ 355MPa, yekutanga sarudzo yemutoro wakakwira, yakakodzera kune yakanyanya kushushikana mamiriro akadai semuchina wechiteshi uye mabhiriji anotsigira. Simba rayo rekusimba rinosvika 470 ~ 630MPa, uye ine yakanaka yakaderera tembiricha kuoma.
(2) Zvinhu zvinokosha
Simbi yakasimba yakasimba: yakadai seS420/S460, inoshandiswa kumidziyo yemagetsi enyukireya uye mabhesi emuchina anorema zvikuru (akadai seUPN350).
Weathering simbi: yakadai seS355J0W, inopesana nekuora kwemhepo, yakakodzera mabhiriji ekunze.
Simbi isina simbi: inoshandiswa munzvimbo dzinoita ngura dzakadai semakemikari nemugungwa, asi nemutengo wakakwira.
(3) Kurapwa kwepamusoro
Kupisa-yakakungurutswa dema: yakasarudzika nzvimbo, inoda yakatevera anti-corrosion kurapwa.
Kupisa-kunyudza galvanizing: galvanized layer ≥ 60μm (senge chiteshi simbi yepombi gallery inotsigira), inovandudza kushorwa.
3. Mazano ekusarudzwa
Mamiriro epamusoro-mutoro (senge port crane rails): Isa pamberi UPN300 ~ UPN350 + S355JR zvinhu kuti uve nechokwadi chekukotama uye kugera kuramba.
Corrosive environment: Sanganisa neinopisa-dip galvanizing kana zvakananga shandisa weathering simbi.
Chiremu chinodiwa: UPN80 ~ UPN120 akatevedzana (mamita uremu 8.6 ~ 13.4kg/m), akakodzera machira emadziro keels uye pombi zvinotsigira.
Ongorora: Paunenge uchitenga, zvinodikanwa kuti uone chirevo chezvinyorwa (maererano ne EN 10025-2) uye dimensional kushivirira (EN 10060) kuve nechokwadi chekuteerera kweprojekiti.
Yakavimbika U Channel Mugadziri Recommendation-Royal Boka
At Royal Group, isu tiri shamwari inotungamira muTianjin's maindasitiri simbi zvinhu zvekutengesa chikamu. Nehunyanzvi uye kuzvipira kuisa pamberi pemhando yepamusoro, isu takazvisimbisa isu kwete chete muU-yakaita simbi, asiwo mune zvese zvimwe zvigadzirwa zvedu.
Chese chigadzirwa chinopihwa neRoyal Boka chinoitwa yakaomesesa yemhando yekuongorora maitiro kuti ive nechokwadi chekuti inosangana kana kudarika emhando yepamusoro zviyero. Izvi zvinotibatsira kupa vatengi vedu zvigadzirwa zvakavimbika uye zvakachengeteka zvakakodzera kune zvakasiyana-siyana zvekushandisa.
Isu tinonzwisisa kuti nguva ndeye musimboti kune vatengi vedu, uye nekudaro, vashandi vedu uye ngarava dzemotokari dzinogara dzakagadzirira kuendesa zvinhu. Nekuona kukurumidza uye kubata nguva, isu tinobatsira vatengi vedu kuchengetedza nguva uye optimize maitiro avo ekuvaka.
Royal Group haingounzi chivimbo mumhando yechigadzirwa uye kukosha, asi zvakare inoratidza kutendeseka muhukama hwevatengi vedu. Isu tinopa kwete chete zvakasiyana-siyana zveU-shaped steel, asiwo zvakasiyana-siyana zvezvimwe zvigadzirwa, zvakadai sesimbi yakagadzirwa neH, I-shaped steel, uye C-shaped steel, kuzadzisa zvinodiwa zvakasiyana-siyana zvevatengi munyika yose.
Yese odha inoiswa neRoyal Group inoongororwa usati wabhadharwa. Vatengi vane kodzero yekuongorora zvigadzirwa zvavo vasati vabhadhara kuti vaone kugutsikana uye kunaka kwechigadzirwa.a
