ASTM A913 Simbi Yakagadzirwa | Simbi yeH-Beam Yakasimba Yezvivakwa zveMaindasitiri neMabhizinesi
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.

7. Ndeapi marapirwo epamusoro aripo?
Tenga pendi yeprimer
Sisitimu yekuputira yeEpoxy kana PU
Kupisa-kunyika
Kuvhara kwekudzivirira ngura kwezvikamu zvakawanda munzvimbo dzemugungwa kana dzemunzvimbo dzinopisa
8. Chimiro chesimbi cheASTM A913 chinogona kugadziriswa here?
Ehe. Hurefu, kurongeka, dhizaini yemutoro, kufukidza, uye nzira dzekubatanidza zvese zvinogona kugadziriswa zvichienderana nedhirowa reprojekiti uye makodhi ekugadzira emunharaunda.
