Shaqada Ardaynta Xoolooyinka Aydhinkiisu ah Qofka Laga Dhisey Guri ee La Isticmaalo Qaybaha Jilbinta

Jilbinta iyo Ka Sii Ilaalinta: Sida Xoolooyinka Aydhinkiisu Ku Sahlan Doonto Qaybaha Jilbinta

Xamirka xanuunaysu waa ku saaraa in kara sida saxda ah ay qofka leh ugaas dhisan tahay. Xanuunayaasha barbardhigga ah waxay ka caawinaysaa natiijooyinka 72% siis badan marka la eego in la tashiiyo iyagoo kaga bilaabma xanuunayaasha gacangal ah, taas waxay noqon kartaa faraha mugga ama dhaadheerka. Xanuunaysu yar yar, waa ka maalin ka wayn in uu hanaqaado dhaadhiska. Tusaale ahaan, xanuunay irro gaaban leh 0.125 inch wuxuu helay in uu ilaaliyo 1,200 pound oo xoog ka dib markuu jabin doono gudaha isku mid ah. Xanuunayaasha yar yar ma hayn tirada xooggaas, waxayna ka yartahay 40%. Xanuunayaasha chisel pointuna waa in kara caawiyaan in aan dhinacaan dhinacaan la dhicin. Tijaabiyaal waxay muujinaysaa in ay dhimmin la dhicin 30% ka hooseeya xanuunayaasha diamond point guud ahaan, taas waxay caawiyaan in lagula saaro xanuunka meelaha ugu weyn baabba’i. Ha kala taabbinna sanafkiisa; sanafyo weyn waxay ku dhaqaaqdaa xooga gudaha xanuunka, taas waxay abuurta isku mid ah ku dhakhsigsan kara.

ASTM F1667 In la xidhnaha: Qiimaha Awoodka Kordhinta Bulshanka

ASTM F1667 wuxuu ka dhigi khat duwaaqada qabaashada ay ka dhigmya iskuulka lamaan ee dhexe-galbeed. Adeegga ayaa tilmaamaya in khamriga khamriga ahaan tahay psi 60,000, u hanaanka saafin saafinta shank (± 0.002 inchi), waxaana talo in la muujiyo in lagu hortagayo xannaaninta ka dib markii la socoto dhisidhda buurta badan 100 saa. Markii abaalmarinayaasha doonayaan inna in naxaasuhuna ay ku taagnaan, tijaabada barakaska sare ayaa muujinaysa in naxaasaha lagu oggolay ay u hortago in la tix qaado xoogga si toos ah 300 paund mar inchi ilaa marka aan dhawaacin jidhka. Tijaabada dunida saxda wax kale ha muujinaysa. Naxaasaha in khatatirinta ASTM ay leeyihiin hadal ka 25 boqolkiiba ka maalin kamaad inta aan la oggolaan. Iyadoo marka kale, waayooyinka ay ka raaceen shaqada dharka dhexdooda waxay sheegiyeen in lagama maarmaanka 90 boqolkiiba ka yar yahay arrimo naxaasaha loo bixiyey gudummada ay soo baxeen markii naxaasaha saxda loo isticmaalay muddo 20 sannad.

Iroon Galvanized iyo Hot-Dipped: Awoodda Fiirsadda ee Dhismeedda ku Tusaaleya Lumber Shaashay iyo Haliyadda Ciniinta

Marka loo eego in la ilaalato dhiciidda korrosion ee dhulka aad u xoog badan ama kemikalo jaban oo jiray, galvanisasiyada ku dhaqanka hadda ayaa si kasto ah uga saamaysan. Qoriyada oo ASTM A153 Class D ka iskudhafan waxay leedahay unsi tokon hoos marfikta (square foot) coverage of zinc, creating a strong bond between metal surfaces that can stand up to stuff like cedar wood extracts and those copper based preservatives found in pressure treated lumber. Hot dipped nails last significantly longer than their electro galvanized counterparts when exposed to salt spray tests showing roughly three to five times better performance. That makes all the difference for buildings near coastlines or inside spaces with high humidity levels. Plus, this type of coating stops those annoying stains that happen when zinc starts to leak out over time, keeping things looking good while maintaining the integrity of whatever structure they're holding together.

Irin kisa Dhexeeya Alloys: Marka Irinka Sareynta Irin ay ku siinayaan Muddo Siinaysiiska Optimal

Macaan kubadka waxay iskudhafaan in kharash ma ahaan doono. Malaqa wuu jabin yahay laakiin ma tirtiri, taas oo macaanka lagu barbardhigiyo mid walba kama tirtirin sida ful istaynjinta ama fulka karbonka qalabka ah. Tanu wa faa'iido si loo xusho korodhaha intii dheer ee sida goobaha gudaha ama dharka ku dhow goobaha aan kastoo badnaaneeyn. Sabab kale oo macaanka ay tahay in ma jiro reyntiisa kimikalka ah leh dhammaan alaabta aasaaska caadiga ah. Haddaad isku daydo inaad galvaanaysato macaano oo la isku daydo lacagta sare iyo dharka copper, waxaad arkeen inay haraamiyaan. Laakiin haddaad macaano kubadka u socoto in ay ku dhisataan fulka pine ama asphalt shingles, waxay ku tiigsan tahay bilaash. Kuwa shaqeeya mashruucaska in aad u baahantahay lacag iyo in nolosha ka yaaba weli, macaanku kubadka waa in ay iskudhafaan. Waxay isku dayeen in ay ku tiigsan yihiin bilaashna marka laga reebo alaabta farcanka ah.

Dhexdhiska, Qaybooyinka Qudha iyo Koverka: Xidhiidhka Loonida Aydhimaha loo Baahan yahay, Dhexeeya iyo Shaacaha Codka

Dooro loonid sax ah sidii kula talagalay sabababta saddex ee muhiim ah: ma baahnaa qof-kariyar, meesha loo isticmaalo, iyo shaacaha codka gurxda. Loonido ring shank waa fiican maxaa yeelay waxay ku tiisataa in la tayo, kadib marka la sheegayo si 70% ka saxis badan loonido gaaban. Tan wuxuu noqdaa mid fiican si loo dhex dhigo iyo xidhiidhka truss meesha ay ku jiraan waxyaabaha inay kor u taagan karaan. Si loo koveriyo ganacsiga, gaar ahaan marka lagu salifinayo meelaha aadka ama deegaanka dibedda, waa in la isticmaalo loonido hot dip galvanized maxaa yeelay waxay ku tiisataa hoonka la cabban kara in la abuuramo adka. Maalin kasta oo aad tahay qaybta qof-kariyarka la hadlay, helitaanka loonido oo dhammaystora ASTM F1667 waa in aanu ogaananno inay ku tiisaan tijaabooyinka waajiba, ilaaliyaan heerar saamaysnida saxsan, iyo inay ku tiisaan in la caddeeyo mar mar kale.

Kanuunka maamulka degmada aadna way ka dhigantahay istiimalidda buubkii ajnabiyeed ee la lahay siyaasadda lagu sayidkaayo sababtoo ah korrosion si degdeg ah — waana in la xaqiijiyo talabooyinka kalsoonida hore loo isticmaalo. Buubkii lacagta la isku raaco ayaa laga saaraan dhibaatooyinka horreeyey ee ku xun, waxayna sii dheeraraya jidhka adeegsiga ilaa 15 sano marka loo eego xaaladaha xun.

Dhibaatooyinka soo galay

Waa maxay faa’iidooyinka loo isticmaalo barashada la dhaqan gariirka?

Barashadu la dhaqan gariirka waxay keenaa xaqiiq si wanaagsan, gaar ahaan dhul-dhalka khamiinta ah ama karuunta saaxilka. Waxay kaloo ilaaliya in gariirku ka siiyo midab marjamaan.

Maxaad tusaale u fahantahay ASTM F1667 ee barashada heer?

In ay barashadu heer ku jiraan ASTM F1667 wuxuu garantiyaa in ay fuliyaan shuruudaha loo baahan yahay ixtisaabka ixtiraam iyo xaqiiq, taasoo keenaysa waaxda iyo awood si wanaagsan marka loo isticmaalo dharka isdhexgalmiga.

Sida barashadu qayl leh loogu yaqaanaya barashada gees sare leh?

Barashadu qayl leh waxay keenaa xiisikad (resistance) 72% si aan ugu badan yihiin barashada gees sare leh, taasoo dhigta inay noqotaa raaxo leh marka loo isticmaalo horumarinta aagga.
