2. Cov khoom siv ntawm cov khoom yuav tsum ua raws li cov kev cai ntawm lub teb chaws tus qauv GB / T 13793-92 "Straight seam welded steel kav" lossis GB / T 3091-2001 "Welded steel kav rau kev thauj mus los ntawm cov dej tsis tshua muaj siab ";
3. Qhov loj me me ua raws li qhov yuav tsum tau ua ntawm JGJ130-2001 "Technical Specification for Safety of Steel Pipe Scaffolding with Couplers in Construction", nrog rau txoj kab uas hla ntawm 48mm thiab qhov tsis zoo siab ntev ntawm 0.5mm; Phab ntsa thickness 3.5mm, tsis zoo kam rau ua 0.5mm.
Cov qauv khoom uas fasteners yuav tsum ua raws li muaj xws li:
1. Scaffold fasteners (ua los ntawm cam khwb cia hlau malleable hlau los yog cam khwb cia hlau) yuav tsum ua raws li tus qauv GB15831-1995 "Steel Pipe Scaffold Fasteners"; 2. Hlau phaj stamping fasteners yuav tsum ua raws li tus qauv JG3061-1999 "Steel Plate Stamping Fasteners". Cov khoom soj ntsuam ntawm cov kav hlau muaj xws li yield zog, elongation, dabtsi yog khoov ntawm cov kav hlau steel, zoo li zoo, sab hauv txoj kab uas hla, phab ntsa thickness, kawg lub ntsej muag sib txawv, thiab lwm yam.
Cov cim tseem ceeb uas yuav tsum tau sim rau cov fasteners suav nrog cov khoom siv kho tshuab, cov tsos ntawm cov fasteners, thiab cov khoom siv zoo.
Cov cuab yeej cuab tam ntawm fasteners feem ntau suav nrog: zawv zawg tsis kam, tsis ua hauj lwm tsis ua hauj lwm, thiab torsional nruj ntawm txoj cai kaum hom fasteners; Kev tiv thaiv plam thiab tiv thaiv tsis ua haujlwm ntawm kev sib hloov hom fasteners; Tensile kev ua tau zoo ntawm docking hom fasteners; Thiab compressive kev ua tau zoo ntawm lub hauv paus (raws li qhia hauv qab no).
Kev Ua Haujlwm Lub Npe: Fastener Hom: Kev Ua Tau Zoo: Thaum tiv thaiv plam txoj cai kaum P{{0}}}0 kN, Δ 1 Tsawg dua lossis sib npaug rau 7.0 hli; Thaum P=10. , Δ 1 Tsawg dua los yog sib npaug rau 7.0 mm; Thaum P=10. } } kN, txhua qhov yuav tsum tsis txhob raug puas tsuaj. Thaum P=17.0 kN, txhua feem yuav tsis raug puas tsuaj. Thaum lub torsional stiffness txoj cai lub kaum sab xis torque yog 900 N · m, θ Tsawg dua los yog sib npaug rau Thaum lub 4 degree tensile pob tw ob leeg tensile zog P=4.0 kN, Δ Tsawg dua los yog sib npaug rau Thaum lub 0 hli compressive puag P=50.0 kN, txhua qhov chaw yuav tsis raug puas tsuaj
Cov tsos thiab accessories zoo ntawm fasteners feem ntau muaj xws li cov nram qab no kaum peb ntsuas:
1. Kev tawg tsis pub nyob rau hauv txhua qhov chaw ntawm lub fastener;
2. Qhov kev ncua deb ntawm lub hau npog thiab lub rooj zaum yuav tsum tsis pub tsawg tshaj 49 (52) mm;
4. Cov fasteners tsis raug tso cai kom txo qis los yog xoob hauv qhov tseem ceeb;
5. Cov xuab zeb qhov nyob rau saum npoo ntawm lub fastener tshaj 10 mm2 yuav tsum tsis txhob ntau tshaj peb qhov chaw, thiab cumulative cheeb tsam yuav tsum tsis txhob ntau tshaj 50 mm2; 5. Qhov sib ntxiv ntawm cov xuab zeb adhering nyob rau saum npoo ntawm fastener yuav tsum tsis txhob ntau tshaj 150 mm2;
6. Lub thawv tsis raug yuav tsum tsis pub tshaj 1 hli;
7. Qhov siab (los yog qhov tob) ntawm lub convex (los yog concave) nto ntawm lub fastener yuav tsum tsis txhob ntau tshaj 1 hli;
