Qaab-dhismeed Xoog Sare leh oo la habeeyey 6 inji 8 inji oo ah Bir kulul oo la duubay H Beam
HABKA SOO SAARKA ALAABTA
Habka wax soo saarka ee birta H-qaabaysan ee dibadda ah badanaa waxaa ka mid ah tallaabooyinka ugu muhiimsan ee soo socda:
Diyaarinta walxaha ceeriin ah: Qalabka ceeriin ee loo isticmaalo soo saarista birta qaabka H badanaa waa billet bir ah. Billet-ka birta ah wuxuu u baahan yahay in la nadiifiyo oo la kululeeyo si loo farsameeyo loona sameeyo.
Habaynta kulul ee duubista: Billet-ka birta ah ee la kululeeyay waxaa loo diraa warshadda duubista kulul si loogu farsameeyo. Warshadda duubista kulul, billet-ka birta ah waxaa lagu rogrogaa rogooyin badan ka dibna si tartiib tartiib ah ayuu u samaysmaa qaabka isgoyska ee birta qaabka H.
Shaqada qabow (ikhtiyaar): Xaaladaha qaarkood, si loo hagaajiyo saxnaanta iyo tayada dusha sare ee birta qaabka H, birta qaabka H ee kulul ee la duubay ayaa sidoo kale lagu farsameyn doonaa qabow, sida duubista qabow, sawirista, iwm.
Jarida iyo Dhammaystirka: Ka dib marka la rogo oo la qabto shaqada qabow, birta qaab-H ah waa in la jaro oo la dhammeeyaa iyadoo la raacayo shuruudaha macaamiisha si loo daboolo baahiyaha cabbirka iyo dhererka gaarka ah.
Daawaynta Dusha sare: Daawaynta nadiifka ah iyo ka hortagga miridhku waxay ka kooban tahay birta qaabaysan ee H si loo hubiyo tayada dusha sare iyo iska caabbinta miridhku ee badeecada.
Kormeerka iyo Baakaynta: Samee kormeer tayo leh oo ku saabsan birta qaabka H-ga ah ee la soo saaray, oo ay ku jiraan kormeerka tayada muuqaalka, saxnaanta cabbirka, sifooyinka farsamada, iwm. Ka dib marka la dhammeeyo imtixaanka, waa la xirxiri doonaa oo diyaar u ah in loo diro macaamiisha.

Darajada: EN10034:1997 EN10163-3:2004
Faahfaahinta: HEA HEB iyo HEM
Heerka: EN
ASTAAMAHA
1. Sifooyinka Farsamada ee aadka u Fiican
Iska caabinta Laab-jilicsan ee Xooggan: Flanges ballaaran oo qaro weyn leh oo leh daqiiqad isdhaafsi oo weyn oo inertia ah (Ix) ayaa si weyn uga sarreeya I-beams (30%-50% ka sarreeya isla miisaanka).
Xasillooni Cadaadis oo Aad u Fiican: Flanges-ku waxay ku toosan yihiin shabakadda, taasoo keenta cadaadis daran oo maxalli ah oo sarreeya, taasoo ka dhigaysa kuwo ku habboon taageerada tiirarka.
Adkaanshaha Biaxial ee Dheelitiran: Daqiiqadaha X- iyo Y-dhidibka ee inertia way isku mid yihiin (tusaale ahaan, nooca HM), taasoo keentay iska caabin xoog oo aad u fiican.
2. Fudud oo Dhaqaale leh
Saamiga Xoogga Sare-ilaa-Miisaanka: 15%-20% ka fudud kuwa caadiga ah ee I-beams si loogu helo awood isku mid ah oo culays-qaadis ah (yaraynta culaysyada dhismaha iyo kharashyada aasaaska).
Keydinta Agabka: Waxtarka sare ee isgoysyada ayaa yareeya isticmaalka birta (tusaale ahaan, dhismaha warshadda oo dhererkeedu yahay 30 mitir, alwaaxyada H waxay isticmaalaan bir ka yar 40% marka loo eego alwaaxyada shubka).
3. Dhisme ku habboon oo hufan
Bolting Fudud: Dusha sare ee flange-ka ayaa sahlaysa bolting-ka xoogga sare leh.
Alxanka oo La Yareeyay: Qaybaha caadiga ah ayaa lagu diyaariyey warshadda, taasoo suurtogalinaysa in si dhakhso ah loogu ururiyo goobta (iyadoo waqtiga dhismaha la dhimayo 30%).
4. Tilmaamaha Qaybaha Kala Duwan ee Aad loo Habeeyey
Heerka Qaranka (GB/T 11263): HW (flange ballaaran), HM (flange dhexdhexaad ah), iyo HN (flange cidhiidhi ah), cabbirrada daboolaya laga bilaabo 100×100 ilaa 1000×300 mm.
Heerka Mareykanka (ASTM A36): Taxanaha W (tusaale ahaan, W12×30) waa mid si guud loo aqbalay.
BAARITAANKA ALAABTA
Shuruudaha baaritaanka birta qaabka H waxaa inta badan ka mid ah dhinacyada soo socda:
Cilladaha Dusha Sare
Lama ogola:
Dildilaac, nabarro, ama laabmo qoto dheer oo ka badan 0.3mm;
Godadka miridhku saameeyaan xoogga (qoto dheer oo ka badan 5% dhumucda derbiga);
Kala-goynta dahaarka Zinc (noocyada u adkaysta daxalka).
Cilladaha yaryar ee la oggol yahay:
Xoqitaannada maxalliga ah ≤ 0.2mm qoto dheer;
Baaxadda calaamadda calaamadda ≤ 1cm²/m².
CODSIGA ALAABTA
H-beam-yada heerka dibadda ah ayaa si weyn loogu isticmaalaa dhinacyada dhismaha iyo injineernimada, oo ay ku jiraan laakiin aan ku xaddidnayn dhinacyada soo socda:
Injineernimada dhismaha, injineernimada buundooyinka, soo saarista mashiinnada, dhismaha maraakiibta, dhismaha qaab-dhismeedka birta,
BAAKADAHA IYO GEYNTA
Baakadaha iyo rarista H-beam-yada caadiga ah ee dibadda waxay badanaa u baahan yihiin raacitaanka tallaabooyinka soo socda:
Baakad: Birta qaabka H waxaa badanaa lagu xidhaa iyadoo loo eegayo shuruudaha macaamiisha si looga ilaaliyo dusha sare ee wasakhda. Hababka caadiga ah ee baakaynta waxaa ka mid ah baakad qaawan, baakad alwaax ah, baakad balaastig ah, iwm. Marka la xidho, waxaa lagama maarmaan ah in la hubiyo in dusha sare ee birta qaabka H aan la xoqin ama aan la miiqin.
Calaamadaynta: Calaamadee macluumaadka badeecada ee ku qoran baakadka, sida nooca, qeexitaanka, tirada, iwm., si loo fududeeyo aqoonsiga iyo maaraynta.
Rarista: Marka la raro oo la raro birta qaabka H-ga ah ee baakadaysan, waxaa lagama maarmaan ah in la hubiyo inaysan jirin wax isku dhac ah ama soo bixitaan ah inta lagu jiro habka rarista si looga fogaado waxyeelada alaabta.
Gaadiidka: Dooro qalabka gaadiidka ee ku habboon, sida gawaarida xamuulka qaada, gaadiidka tareenka, iwm., oo dooro habka gaadiidka ee ku habboon iyadoo loo eegayo shuruudaha macaamiisha iyo masaafada gaadiidka.
Soo dejinta: Ka dib marka la gaaro meesha loo socdo, hawsha dejinta waa in si taxaddar leh loo sameeyaa si looga fogaado waxyeelada soo gaarta birta qaabka H.
Kaydinta: Birta qaabka H ku kaydi bakhaar qalalan oo hawo leh si looga fogaado qoyaanka ama waxyeellooyinka kale ee xun.
AWOODDA SHIRKADDA
Su'aalaha Badiya La Weydiiyo
1. Sideen kaaga heli karaa xigasho?
Waad noo dhaafi kartaa farriin, waxaanan ka jawaabi doonnaa farriin kasta waqtigeeda.
2. Ma alaabta ku geyn doontaa waqtigii loogu talagalay?
