Dhererka birta labajibbaaran waxaa lagu qeexay sida soo socota.
A. Dhererka caadiga ah (ma aha dherer go'an).
Birta caadiga ah.
Dhererka dhinaca ≤ 25mm ......................................................... .. dhererka 5 ~ 10m
Dhererka dhinaca 26 ~ 50mm ................................. .......... dhererka 4 ~ 9m
Dhererka dhinaca 53 ~ 110mm ................................................ ......... dhererka 4 ~8m
Dhererka dhinaca ≥120mm .............................................. Dhererka 3 ~ 6m
Bir tayo sare leh.
Cabirrada dhererka dhinac ee kala duwan ............................ ............... dhererka 2 ~ 6m
B. Dhererka go'an (oo lagu go'aamiyay qandaraaska)
C. Dherer badan (oo lagu go'aamiyay heshiiska)
Afar geesoodka birta ah waxaa inta badan loo isticmaalaa in badan marka la dhammeeyo, sida albaabbada iyo daaqadaha.
Hot giringiriyey bir afar gees ah
Bir labajibbaaran oo kulul, waa bir la rogmaday ama lagu rakibay qayb iskutallaabta afar gees ah.Birta labajibbaaran waxaa loo qaybin karaa laba nooc:-kulul iyo qabow-duuban;birta labajibbaaran ee kulul waxay leedahay dherer dhinac ah oo ah 5-250mm iyo birta labajibbaaran ee qabow waxay leedahay dherer dhan 3-100mm.
Birta labajibbaaran
[square steel] bir la rogmaday ama laga shaqeeyay qayb iskutallaab ah oo afar gees ah
Cufnaanta birta waa: 7.851g/cm3
Xisaabinta miisaanka aragtida ee birta
Halbeegga cabbiraadda xisaabinta miisaanka aragtida birta waa kiilooga (kg).Habka aasaasiga ah waa.
W (miisaanka, kg) = F (aagga isgoyska mm2) × L (dhererka, m) × ρ (cufnaanta, g/cm3) × 1/1000
Birta labajibbaaran waxaa loo qaybin karaa laba nooc:-kulul iyo qabow-duuban;bir labajibbaaran oo kulul oo dhererkeedu dhan yahay 5-250mm iyo bir labajibbaaran oo qabow leh oo dhererkeedu yahay 3-100mm.
Bir afar gees ah oo qabow-sawirran
Bir labajibbaaran ee qabow-jiidaan waxa loola jeedaa birta qabow-jiiday oo leh qaab labajibbaaran oo been abuur ah
Bir labajibbaaran ee qaboow-jiidaan ah waxaa loola jeedaa birta qabow-jiiday oo qaab labajibbaaran leh.
Birta qaboojiso waxaa si xoog ah loogu fidiyaa birta hoosteeda xaaladaha heerkulka qolka oo leh cadaadis xoog leh oo dhaafsiisan xoogga dhibicda dhalidda ee birta asalka ah si loo soo saaro qallafsanaanta caagga ah ee birta birta si loo hagaajiyo dhibcaha wax-soo-saarka ee birta birta loona badbaadiyo birta ujeedada .
Sawirka qabow waa isticmaalka tikniyoolajiyada extrusion qabow, iyada oo loo marayo dhimashada saxda ah, ka soo saar dhammaan noocyada saxda ah ee saxda ah, birta wareegsan ee siman, birta laba jibbaaran, birta siman, birta lix geesoodka ah iyo birta kale ee qaabaysan.
Fikradda sawir qabow ee baararka birta: si loo badbaadiyo birta, hagaajinta xoogga wax-soo-saarka biraha birta ee ujeedada culeyska culeyska ee ka baxsan xoogga dhalidda iyo in ka yar xoogga ugu dambeeya si loo kala bixiyo birta birta, si ay u dhaqmaan qallafsanaanta caagga ah waa loo yaqaan sawir qabow ee baararka birta.
Bir laba jibaaran oo aan bir lahayn
[square steel] la rogmaday ama lagu habeeyey qayb iskutallaab ah oo afar gees ah
Bir laba jibaaran oo aan bir lahayn
Xisaabinta miisaanka aragtida ee birta
Halbeegga cabbiraadda xisaabinta miisaanka aragtida birta waa kiilooga (kg).Habka aasaasiga ah waa.
W (miisaanka, kg) = F (aagga isgoyska mm2) × L (dhererka, m) × ρ (cufnaanta, g/cm3) × 1/1000
Isticmaalka alaabta
Birta labajibbaaran ee birta ah ayaa inta badan loo isticmaalaa dhamaystirka, sida albaabbada iyo daaqadaha.
Tilmaamaha alaabta
Bir afar gees leh oo dhalaalaysa qabow: 3×3mm-80×80mm
Bir labajibbaaran oo qalloocan
Dhexroorka birta labajibbaaran ee qalloocan waa 4mm - 10mm, qeexitaannada guud waa 6 * 6mm iyo 5 * 5mm, kuwaas oo laga soo leexiyay 8mm iyo 6.5mm walxaha gariiradda dhexroorka ah ee la soo saaray oo la leexiyay siday u kala horreeyaan.
Qalabka: Q235.
Torque: wareegtada caadiga ah ee 120mm/360 darajo, wareegga caadiga ahi waa mid qurux badan oo la taaban karo.
Isticmaal: Si ballaaran loo isticmaalo shabageynta birta, qaab dhismeedka birta ama shubka la xoojiyay si loogu beddelo rebar.
Faa'iidooyinka: birta labajibbaaran ee qalloocan iyo qalloocan waxay kordhisaa xoogga jilicsan ee qaabka, muuqaalka quruxda badan, si weyn u yareynaya kharashka raasumaalka;geeso fiiqan, dhexroor sax ah.
