EN H-qaabaynta Biraha Dhismaha h Beam
H-beambirta ayaa si weyn loo isticmaalaa, inta badan waxaa loo isticmaalaa: noocyo kala duwan oo dhismaha dhismaha madaniga ah iyo warshadaha; Noocyo kala duwan oo warshado warshado ah oo dhaadheer leh iyo dhismayaal dhaadheer oo casri ah, gaar ahaan meelaha ay ku badan yihiin dhaqdhaqaaqa seismic iyo xaaladaha heerkulka sare ee shaqada; Buundooyin waaweyn oo leh awood ballaaran, xasillooni iskutallaab ah iyo baaxad weyn ayaa loo baahan yahay; Qalab culus; Jidka weyn; Qalfoofka markabka; Taageerada miinada; Daaweynta aasaasiga ah iyo injineernimada biyo xireenka; Qaybaha mashiinka kala duwan.
HABKA SOO SAARIDA WAX soo saarka
Flange eeH beamwaa barbar socda ama ku dhawaad isbarbar socda gudaha iyo dibadda, iyo dhamaadka flange waa xagal sax ah, sidaas darteed waxa loogu magac daray flange I-steel. Dhumucda shabkada birta H-qaabeeya way ka yar tahay tan caadiga ah ee I-beams leh dhererka isku midka ah ee webka, iyo ballaca flangegu wuu ka weyn yahay kan caadiga ah ee I-beams oo leh dherer isku mid ah oo shabakada ah, sidaas darteed waxaa sidoo kale loogu magac daray I-beams ballaaran. Waxaa lagu go'aamiyay qaabka, modules-ka qaybta, daqiiqada firfircoonida iyo xoogga u dhigma ee H-beam ayaa si cad uga fiican kan I-beam caadiga ah oo leh miisaan isku mid ah. Loo isticmaalo shuruudaha kala duwan ee qaab dhismeedka biraha, haddii ay ku hoos foorarsado torque, culayska cadaadiska, load eccentric muujinaysaa waxqabadkeeda sare, si weyn u hagaajin kara awoodda dhalista ka badan I-birta caadiga ah, badbaadinta biraha 10% ~ 40%. Birta H-qaabaysan waxay leedahay flange ballaaran, shabakad dhuuban, tilmaamo badan, iyo isticmaal dabacsan, kaas oo badbaadin kara 15% ilaa 20% birta qaab dhismeedka kala duwan ee truss. Sababtoo ah garabkiisu waa barbar socda gudaha iyo dibadda, cidhifkuna waa xagal toosan, way fududahay in la isku keeno oo la isku daro qaybo kala duwan, taas oo badbaadin karta qiyaastii 25% culeyska alxanka iyo qulqulka shaqada, waxayna si weyn u dardargelin kartaa xawaaraha dhismaha mashruuca waxayna soo gaabin kartaa muddada dhismaha.

MEESHA
Waxaa jira tilmaamo badan oo alaabtaH-beam, iyo hababka kala soocida waa sida soo socota. Birta birta ah ee nooca H-nooca, tiirarka birta nooca H-nooca, H-nooca birta birta ah iyo birta nooca H oo leh flange aad u qaro weyn Sidaa darteed, waxaa sidoo kale loo yaqaannaa birta H-beam iyo tiirarka H-beam steel. (3) Marka loo eego habka wax soo saarka, waxay u qaybsan tahay birta H-beam welded iyo birta H-beam duuban. (4) Marka loo eego cabbirada cabbirka waxaa loo qaybiyaa bir-qaab weyn, dhexdhexaad ah iyo mid yar oo H-qaabeeya. Guud ahaan, alaabada leh dhererka webka H ee ka sarreeya 700mm waxaa loogu yeeraa waaweyn, 300 ~ 700mm waxaa loogu yeeraa dhexdhexaad, kuwa ka yar 300mm waxaa loogu yeeraa small.Dhammaadka 1990, dhererka webiga H-beam ee ugu weyn adduunka ee 1200mm width fla 3.
KORMEERKA Alaabada
Shuruudaha kormeerka birta-qaabeeya ee H inta badan waxaa ka mid ah dhinacyada soo socda:
Tayada muuqaalka: Tayada muuqaalka birta-qaabaysan ee H waa in ay u hoggaansamaan heerarka khuseeya iyo shuruudaha dalbashada. Dusha sare waa inay noqotaa mid siman oo siman, oo aan lahayn jeexjeexyo muuqda, xoqan, miridhku iyo cillado kale.
Cabirka joomatari: Dhererka, balladhka, dhererka, dhumucda webka, dhumucda flange iyo cabbirada kale ee birta-qaabaysan waa in ay u hoggaansamaan heerarka khuseeya iyo shuruudaha dalbashada.
Curvature: Qallooca birta qaabaysan ee H waa in ay u hoggaansamaan heerarka khuseeya iyo shuruudaha dalbashada. Waxa lagu ogaan karaa marka la cabbiro in diyaaradaha labada daraf ee birta u qaabaysan H ay barbar socdaan ama la isticmaalayo mitir foorarsi ah.
Maroojin: Qallooca birta-qaabaysan ee H waa in ay u hoggaansamaan heerarka khuseeya iyo shuruudaha dalbashada. Waxa lagu ogaan karaa marka la cabbiro in dhinaca birta-qaabka H-ku ay taagan tahay ama ay mitirka maroojinayso.
Weelashada miisaanka: Miisaanka birta-qaabaysan ee H waa in ay u hoggaansamaan heerarka khuseeya iyo shuruudaha dalbashada. Miisaanka leexashada waxaa lagu ogaan karaa miisaan.
Halabuurka Kiimikada: Haddii birta H-qaabaysan ay u baahan tahay in la alxanayo ama si kale loo farsameeyo, ka kooban yahay kiimiko waa in ay u hoggaansamaan heerarka khuseeya iyo shuruudaha dalbashada.
Guryaha makaanikada: Qalabka farsamada ee birta-qaabeeya waa in ay u hoggaansamaan heerarka la xiriira iyo shuruudaha dalbashada, oo ay ku jiraan xoogga cufan, dhibicda dhalidda, dhererka iyo tilmaamayaasha kale.
Tijaabada aan burburin: Haddii birta qaabka H u baahan tahay tijaabo aan burburin, waa in la tijaabiyaa si waafaqsan heerarka la xiriira iyo shuruudaha dalbashada si loo hubiyo in tayada gudaha ay wanaagsan tahay.
Baakaynta iyo calaamadaynta: Baakaynta iyo calaamadaynta birta qaabaysan ee H waa inay u hoggaansamaan heerarka khuseeya iyo shuruudaha dalbashada si loo fududeeyo gaadiidka iyo kaydinta.
Marka la soo koobo, shuruudaha kor ku xusan waa in si buuxda loo tixgeliyo marka la eegayo H-qaabeeya birta si loo hubiyo in tayadiisa ay la kulanto heerarka ku habboon iyo shuruudaha dalbashada, iyo in la siiyo dadka isticmaala alaabta ugu fiican ee H-qaabeeya.
Codsiga
CaadiyanH-beamQalabka birta ah waxaa ka mid ah Q235B, SM490, SS400, Q345 iyo Q345B. Halabuurka kiimikada iyo sifooyinka farsamada ee qalabkani way kala duwan yihiin, markaa markaad dooranayso isticmaalka H-beam, waa lagama maarmaan in la doorto walxaha ku habboon iyadoo loo eegayo xaaladda gaarka ah.
Baakadaha iyo raritaanka
Baakadaha iyo ilaalinta:
Baakadu waxay door muhiim ah ka ciyaartaa ilaalinta tayada ASTM A36H beambirta inta lagu jiro gaadiidka iyo kaydinta. Walaxda waa in si ammaan ah loo xidhaa, iyadoo la isticmaalayo xargaha ama xargaha xoogga sare leh si looga hortago dhaqdhaqaaqa iyo waxyeellada iman karta. Intaa waxaa dheer, waa in la qaado tillaabooyin si looga ilaaliyo birta inay soo gaarto qoyaanka, boodhka, iyo arrimaha kale ee deegaanka. Isku-dubbaridyada xidhmooyinku ku dhejiyaan walxaha cimilada u adkaysta, sida balaastigga ama marada biyuhu, waxay ka caawisaa ka hortagga daxalka iyo miridhku.
