1. H Tilmaamaha Beam ee ku salaysan Heerarka Caalamiga ah

Tilmaamaha Taxanaha W:
Tilmaamaha waxay ku salaysan yihiin "Cross-Section Height (inji) x Miisaanka cagtiiba (pounds)." Alaabooyinka muhiimka ah waxaa ka mid ahW8x10 H Beam, W8x40 H BeamiyoW16x89 H Beam. Waxaa ka mid ah, W8x10 H Beam waxay leedahay dhererka qayb ee 8 inji (qiyaastii 203mm), culeyska 10 rodol cagtiiba (qiyaastii 14.88kg/m), dhumucdiisuna tahay 0.245 inji (qiyaastii 6.22mm), iyo balac 4.015 inji ah (qiyaastii 102mm). Waxay ku habboon tahay muraayadaha sawir-qaadista iyo muraayadaha sare ee yaryarH Beam Steel Dhismayaasha; W8x40 H Beam waxa uu leeyahay miisaan 40 rodol cagtiiba (qiyaastii 59.54kg/m), dhumucdiisuna tahay 0.365 inji (qiyaastii 9.27mm), iyo balac balac ah 8.115 inji (qiyaastii 206mm). Awoodda culeyska ayaa labanlaabantay waxaana loo isticmaali karaa sida muraayadda ugu weyn ee warshadaha dhexdhexaadka ah; W16x89 H Beam wuxuu leeyahay dhererka qayb ee 16 inji (qiyaastii 406mm), culeyskiisu yahay 89 rodol cagtiiba (qiyaastii 132.5kg/m), dhumucdiisuna tahay 0.485 inch (qiyaastii 12.32mm), iyo balladhka flange ee 10.315 inch (qiyaastii 262mm) dherer gaar ah ayaa loo qaabeeyey H-beam dhismooyinka birta ah iyo dhismayaasha buundada culayska leh.

Tilmaamaha heerka Yurub:
Tani waxay daboolaysaa laba nooc: HEA H-beam iyo UPN H-beam. Tilmaamaha waxaa lagu tilmaamay inay yihiin "Dharka Qaybta (mm) × Ballaca Qaybta (mm) × Dhumucda Webka (mm) × Dhumucda Flange (mm)."HEA H iftiinkawaa wakiil ka mid ah qaybaha birta ballaaran ee Yurub. Tusaale ahaan, qeexida HEA 100 waxay leedahay qayb dhererkeedu yahay 100mm, ballac 100mm, dhumucdiisuna tahay 6mm, iyo dhumucdiisuna tahay 8mm. Miisaankeeda aragtiyeed waa 16.7kg/m, isku darka caabbinta khafiifka ah iyo torsional. Caadi ahaan waxaa loo adeegsadaa saldhigyada mishiinada iyo xargaha qalabka.UPN H muraayadahaDhanka kale, waxay leeyihiin qaybo cidhiidhi ah. Tusaale ahaan, UPN 100 waxay leedahay dherer qaybeed 100mm, ballac 50mm, dhumucdiisuna tahay 5mm, dhumucdiisuna tahay 7mm. Miisaankiisa aragtiyeed waa 8.6kg/m. Sababtoo ah qaybta isku-dhafka ah ee isku-dhafka ah, waxay ku habboon tahay nalalka qaab-dhismeedka birta ee bannaan ee xaddidan, sida taageerada gidaarka daahyada iyo tiirarka qalabka yaryar.

2. H Qeexitaannada Beam ee kuxiran Maaddada

H Noqoam Q235b Tilmaamaha:
Sida heerka qaranka ShiinahaBir-kaarboon-hooseeya H-beam, Tilmaamaha asaasiga ah waxay daboolayaan cabbirada caadiga ah ee H Beam 100 ilaa H Beam 250. H Beam 100 (qaybta iskutallaabta: dhererka 100mm, 100mm ballac, 6mm web, 8mm flange; miisaanka aragtida: 17.2kg / m) iyo H Beam 250 (dhirrada 250mm, ballac 25mm, ballac 25mm) 9mm web, 14mm flange; miisaanka aragtida: 63.8kg/m) waxay bixisaa awood dhalidda ≥ 235MPa, alxanka heer sare ah, oo waxaa laga baaraandegi karaa iyada oo aan hore u kululayn. Waxa ugu horrayn loo adeegsadaa alwaaxyada iyo tiirarka warshadaha gudaha ee yaryar iyo kuwa dhexdhexaadka ah iyo dhismayaal la deggan yahay oo bir-qaabaysan oo dabaqyo badan leh, kuwaas oo bixinaya qeexid ujeedo guud oo qiimo-sare leh.

Tilmaamaha Taxanaha ASTM H Beam:
Iyada oo ku saleysanASTM A36 H BeamiyoA992 Balaadhan Flange H Beam. ASTM A36 H Beam waxay leedahay awood wax-soo-saar ≥250 MPa waxaana lagu heli karaa cabbirro laga bilaabo W6x9 ilaa W24x192. W10x33 sida caadiga ah loo isticmaalo (dhererka qaybta 10.31 inches × flange width 6.52 inches, miisaanka 33 rodol cagtiiba) ayaa ku haboon qaab dhismeedka rarka ee dhirta warshadaha iyo bakhaarada dibada. A992 Wide Flange H Beam, qayb adag oo ballaaran oo bir ah (nooca wakiil ka ah H Beam Wide Flange), wuxuu leeyahay awoodda wax soo saarka ee ≥345 MPa waxaana ugu horreyn lagu heli karaa cabbirrada W12x65 (qaybta dhererka 12.19 inji × flange ballac 12.01 inji, miisaanka 65 rodol 4 x 9 inch flange) ballac 14.02 inji, miisaanka 90 rodol cagtiiba). Waxaa loogu talagalay fiimyada dhismooyinka dhaadheer iyo alwaaxyada wiishka ee culus, waxayna u adkeysan kartaa culeysyo firfircoon iyo saameyno daran.

3. Isku-dubbaridka Is-beddelka iyo Midaynta

Habbee Tilmaamaha Birta Kaarboon-H Beam:
Dhererka qaybta iskutallaabta ee la beddeli karo (50mm-1000mm), dhumucda webka/flange (3mm-50mm), dhererka (6m-30m), iyo daawaynta dusha sare (galvanizing, daahan ka-hortagga daxalka) ayaa diyaar ah. Tusaale ahaan, birta kaarboonka ee daxalka u adkaysata ee leh dhererka qaybta 500mm, dhumucdiisuna tahay 20mm, dhumucdiisuna tahay 30mm ayaa loo habeyn karaa mashaariicda xeebaha. Aasaaska qalabka culus, flange-ka dheer ee flange-ka dheer ee leh dhererka 24m iyo dhererka qaybta 800mm ayaa loo habeyn karaa si loo buuxiyo shuruudaha xamuulka ee aan caadiga ahayn.

Tilmaamaha Guud ee Birta H-Beam:
Marka lagu daro qeexitaannada aan soo sheegnay, tilmaamaha guud waxaa ka mid ah HeaCibraaniga 150(150mm × 150mm × 7mm × 10mm, miisaanka aragtida 31.9kg/m) iyo H Beam 300 (300mm × 300mm × 10mm × 15mm, miisaanka aragtida 85.1kg/m). Kuwaas waxaa si weyn loogu isticmaalaa codsiyada sida dhufto ee qaab dhismeedka birta, taageero ku meel gaar ah, iyo looxyada weel, samaynta shax qeexid dhamaystiran oo u dhexeeya fudud ilaa culus, iyo heerka ilaa la habeeyey.
