Habka wax soo saarka wax soo saarka
Flale ofNWaa is barbar dhig ama ku dhawaad barbar socda gudaha iyo dibedda, dhamaadka Flanges waxay ku jirtaa xagal qumman, sidaa darteed waxaa loo magacaabay isbarbar dhig nabarro ah. Dhumucda websaydhka websaydhka birta H-qaabeysan ayaa ka yar tii-xumada caadiga ah ee isla dhererkiisu yahay shabakadda, oo ballaca of flaugga ah ayaa ka weyn kan imadka caadiga ah ee websaydhka. Sidaas oo kale waxaa loo magacaabay Iim Iim I-laambada. Waxaa lagu go'aamiyay qaabka, qaybta modulus, daqiiqad ka mid ah gudaha iyo xoogga u dhigma ee H-ilaax ayaa si cad uga fiican kuwa caadiga ah ee isku midka ah miisaanka keliya. Waxaa loo adeegsaday shuruudo kala duwan oo qaab dhismeedka birta ah, ha ahaato in ay hoos udhacdo xargaha cadaadiska, rarka cadaadiska, waxay si weyn u wanaajin kartaa kartida sicirka marka loo eego I-birta caadiga ah, oo ah badbaadinta birta 10% ~ 40%. Birta H-qaabeysan waxay leedahay wax ballaaran, dhuuban oo dhuuban, faahfaahinno badan, iyo adeegsi dabacsan, oo badbaadin kara 15% illaa 20% birta ee qaabdhismeedka kala duwan ee tras. Sababtoo ah Flaller-ka waa is barbar socda gudaha iyo banaanka, geeskuna waa xagal qumman, way fududahay in la isugu yeedho oo lagu daro qaybo ka mid ah 25% oo ka mid ah alxanka iyo xadka shaqada, waxayna si weyn u dadajin kartaa xawaaraha dhismaha ee mashruuca oo gaabiya xilliga dhismaha.

(2) Marka loo eego isticmaalka wax soo saarka, waxaa loo qaybiyaa nambarka birta ee nooca H-Nooca ee The Stel Stel, H-Nooc bir ah oo bir ah oo bir bir ah oo aad u qafiif ah Waxaa ku jira tirada kala duwan ee H-CULS.GEERY, STARWARKA SOO DHAWAAN H-CARG STEEN waxaa loo isticmaalaa jahwareerka sida nambarka iyo nalka H-chygen bir bir ah loo isticmaalo safka. Sidaas awgeed, waxaa sidoo kale loo yaqaanaa bember h-bember bir bir ah iyo safka hore ee bir bir ah. (3) Sida ku xusan habka wax soo saarka, waxay u qaybsan tahay bir bir ah oo la duubay oo bir bir ah oo duudduuban. (4) Sida ku xusan tilmaanta cabirka waxay u qaybsantahay bir weyn, dhexdhexaad ah iyo kuwa yaryar oo qaab leh, alaabooyin leh websaydh hoosaadh ah oo ka sarreysa 700mmm waxaa loo yaqaannaa mid ballaaran, 300mm 700mm ah waxaa loo yaqaan dhexdhexaad, kuwaasoo ka yar 300mm waxaa loo yaqaan kuwa yar.

Baadhista alaabada
Shuruudaha kormeerka birta ee qaabaysan ee H-qaabeysan waxaa ka mid ah dhinacyada soo socda:
Tayada muuqaalka: Tayada muuqaalka birta H-qaabeeya waa inuu u hoggaansamaa heerarka ku habboon iyo shuruudaha dalbashada. Dusha sare waa inay ahaato mid siman oo siman, oo aan lahayn ilko cad, xoqitaan, miridhku iyo cilado kale.
Cabbirka joomatari: Dhererka, ballaca, dhumucda, dhumucda qafiifka ah iyo cabbir kale oo bir bir ah waa inuu u hoggaansanaadaa heerarka H-qaabeeya ee H-Moodhadhka ah inuu u hoggaansamo heerarka ku habboon iyo shuruudaha dalbashada.
Curviult: Curvup-ka birta h-qaabeysan waa inay u hoggaansanaataa heerarka ku habboon iyo shuruudaha dalbashada. Waxaa lagu ogaan karaa iyadoo la cabbiro in diyaaradaha labada dhinac ee birta H-qaabeysan ay isbarbar dhigayaan ama adeegsadaan mitirka foosha.
Maroojin: maroojin ka timaadda birta h-qaabeysan waa inuu u hoggaansamaa heerarka ku habboon iyo shuruudaha dalbashada. Waxaa lagu ogaan karaa iyadoo la cabbirayo in dhinaca birta H-qaabeysan ay tahay mid toosan ama mitir maroojin.
Xannaanaynta Miisaanka: Miisaanka birta H-qaabeeya waa inuu u hoggaansamaa heerarka ku habboon iyo shuruudaha dalbashada. Dagaallada culeyska waxaa lagu ogaan karaa miisaanka.
Isku-darka kiimikada: Haddii birta H-qaabeysan ay u baahan tahay in la qariyo ama si kale loo farsameeyo, halaheeda kiimikaadku waa inay u hoggaansamaan heerarka ku habboon iyo shuruudaha dalabka.
Guryaha farsamada leh
Tijaabada aan burburin: Haddii birta h-qaabeysan u baahan tahay baaritaan aan dumin, waa in la baaraa iyada oo la raacayo heerarka ku habboon iyo dalbashada shuruudaha si loo hubiyo in tayadeeda gudaha ay fiicantahay.
Baakadaha iyo calaamadaynta: baakadaha iyo calaamadaynta birta H-qaabeeya waa inay u hoggaansamaan heerarka ku habboon iyo dalbashada shuruudaha si loo fududeeyo gaadiidka iyo kaydinta.
Marka la soo koobo, shuruudaha kor ku xusan waa in si buuxda loo tixgeliyaa marka la baarayo bir bir ah si loo hubiyo in tayadoodu ku buuxinayso heerarka ku habboon iyo dalbashada shuruudaha, iyo in ay isticmaalaan alaabada ugu fiican ee birta ugu fiican.

Baakadaha iyo dhoofinta
Baakadaha iyo Ilaalinta:
Baakaduhu waxay door muhiim ah ka ciyaaraan ilaalinta tayada ASTM A36Nbirta inta lagu gudajiro gaadiidka iyo kaydinta. Qalabka waa in si ammaan ah loo xirxiraa, iyadoo la adeegsanayo xargaha xoog sare ama xargaha si looga hortago dhaqdhaqaaqa iyo waxyeelada suurta galka ah. Intaa waxaa sii dheer, tillaabooyinka waa in la qaadaa si looga ilaaliyo birta ka soo gaadho qoyaanka, boodhka, iyo sababaha kale ee deegaanka. Ku duuban xidhmooyinka ee shey u adkaysta cimilada, sida maro caag ah ama biyo-celin ah, waxay ka caawineysaa kahortaga saxaafadda iyo miridhku.
