Chubhu yemativi manaimhando yechubhu yesimbi ine mativi mana isina chinhu, inozivikanwawo sechubhu yemativi mana,chubhu yerectangular. Tsanangudzo yayo inoratidzwa ne mm yedhayamita yekunze * ukobvu hwemadziro. Yakagadzirwa nesimbi inoputirwa inopisa nekudhonza inotonhora kana kudhirowa inotonhora.
Kushandisa pombi yemativi isina musono:
Sikweya isina musono uyeyuantai rectangular chubhuanoshandiswa zvakanyanya. Anoshandiswa zvakanyanya kugadzira zvikamu zvechivakwa uye zvikamu zvemakanika, zvakaita sepombi yekuboorera mafuta, mugodhi wekutumira mota, furemu yebhasikoro uye scaffolding yesimbi inoshandiswa mukuvaka, izvo zvakagadzirwa nesimbi yemhando yepamusoro yecarbon structural nekupisa kana kudhirowa kunotonhora, uye zvinonyanya kushandiswa semapaipi kana zvikamu zvechivakwa kutakura mvura.
Rudzi rwechubhu ine musono ye rectangular:
1. Zvichienderana nechinhu chacho, chinogona kukamurwa kuita simbi yekuvaka kabhoni yakajairika uye simbi yekuvaka ine simba rakaderera. Huremu hwekabhoni hwechinhu chekutanga hahufanirwe kudarika 4.5%; sarufa ≤ 0.035; phosphorus ≤ 0.005; chromium ≤ 0.15; nickel content <0.25; mhangura ≤ 0.30; Chekupedzisira chine silicon, manganese uye vanadium shoma pamwe chete nekabhoni, sarufa, phosphorus uye chromium.
2. Zvichienderana nehukuru hwepamusoro:
(1) Kupedzisa:
1 Nzvimbo dzemukati nedzekunze dzechubhu ine musono inofanira kunge yakatsetseka uye yakati sandara isina maburi nemakwinya.
2 Kana nzvimbo yemukati iri pasi pe100 mm2, kutsungirira kunobvumirwa kwenzvimbo yemukati ndeye ± 0.2 mm.
3 Kana nzvimbo yemukati memvura yakakura kupfuura 100 mm2, kutsungirira kunobvumirwa kwenzvimbo yemukati memvura i± 0.5 mm.
4 Hapana mitswe kana mapete anotenderwa pamusoro pemukati; 5 Hapana vanga 6 Hapana mavanga ari pachena uye mavanga ekukuvadzwa.
(2) Kufara:
1 Nzvimbo dzemukati nedzekunze dzemachubhu akaenzana asina musono dzinofanira kunge dzakati sandara uye dzakatsetseka.
2 Hapafanirwe kuve nekusaenzana kuri pachena kana kuchionekwa negirazi rinokudza re10X.
3 Kuguma kwemuromo wemuromo kwakatarisana nepakati pepombi.
4 Kumucheto kwegomba repombi hakufanirwe kunge kusina maburi.
5 Hapana kukwenya pakukombama kwepombi.
6 Migumo yese yepombi inofanira kunge yakaenzana.
7 Hapana bundu riri pachena rinotenderwa pakunamira mushure mekubvisa ngura.
8 Hapafanirwe kuva nemakomba akajeka.
9 Hapana zvikanganiso zvinokanganisa kushandiswa zvinotenderwa.
10 Kana muchina wekumonera plate uchishandiswa pakumonera, hupamhi hwefillet paweld hahufanirwe kunge huri pasi peukobvu hwesimbi yepasi.
(3) Kururama kwehukuru:
1 Kukanganisa kwekutenderera hakufanirwe kudarika kutsauka kukuru kwakataurwa muchiyero chakakodzera nekupfuura 2 mm/m2.
2 Kururama uye kutsauka kwekona hazvifanirwe kudarika 1/20 yekutsauka kukuru kwakataurwa muchiyero chinoenderana.
3 Kutsauka kwemuganhu wehurefu hakufanirwe kupfuura ka1.5 kehuwandu hwacho hwakaenzana.
Kudzora mhando yepombi yesimbi yeyuantaiyakaoma zvikuru, saka vatengi vanogona kusarudza nechivimbo.Yuantai kambaniNdakawana mapatenti makumi manomwe nemanomwe,Yuantai simbiyakahwina mubairo we single champion we rectangular tube industry kwemakore gumi akatevedzana,
Kana uchida kuwanamutengo wepombi yesimbi yeyuantai，Ndapota taurai nesu.
