EN 1065 Cov Khoom Siv

——————————————————————————————————————

EUROPEAN Standard EN 1065

Cov txheej txheem no tau teeb tsa cov kev cai tsim nyog rau kev kho kom zoo nkauj telescopic steel props nrog qhib

xov. Tus txheej txheem npog cov khoom ncaj nraim nkaus xwb.

Lub hom phiaj ntawm EN 1065 yog txhawm rau txheeb xyuas cov yam ntxwv ntawm cov khoom siv hlau raws li kev nyab xeeb thiab thauj khoom

bearing, muab cov khoom no ua 4 pawg (B, C, D, E).

1. A Prop yog suav tias yog ua raws li cov kev cai tsuav yog nws muaj cov khoom nram qab no:

2. Ib qho kev tiv thaiv tes-nraug qhov ntev ntawm qhov tsawg kawg yog 100mm.

3. Yam tsawg kawg yog 300 hli ntawm lub raj sab hauv yuav tsum nyob hauv lub raj sab nraud thaum lub prop yog tag nrho txuas.

4. Lub kaw lus ruaj khov ua rau nws tsis tuaj yeem ua rau cov raj sab hauv thiab sab nrauv tuaj sib nrug.

5. Lub kaw lus ua rau nws tsis yooj yim rau cov cuab yeej kho kom plam tawm nws cov xov.

6. Qhov tsawg kawg nkaus adjustability ntawm yam tsawg kawg yog 1 meter

(Length sib txawv ntawm tag nrho-extended thiab tag nrho-compressed)

- Txuas tus pin nrog nominal txoj kab uas hla ntau dua 13mm.

- Lub prop yuav tsum ua kom tiav cov cai hauv qab no:

Lub diameters thiab thickness ntawm lub puab thiab sab hauv raj yuav tsum tau teev kom thiaj li xeem (los ntawm

xam los yog los ntawm kev ntsuam xyuas siab) txiav txim siab ib tug txaus siab vau load raws li txhais rau lub 4

pawg ntawm cov khoom siv, nrog rau cov qauv hauv qab no.

Nominal txoj kab uas hla ntawm tus pin yuav tsum tsis pub tsawg tshaj 13 hli.

- Tus pin yuav tsum tau txuas nrog lub prop kom nws tsis tuaj yeem raug tshem tawm tsis txhob txwm ua.

- Cov raj sab hauv thiab sab nrauv ntawm lub prop yuav tsum muaj kev tiv thaiv mus tas li tiv thaiv tsis txhob xav

kev tshem tawm.

- Cov phaj kawg yuav tsum yog square [SQ] lossis zoo li [SH]. Lawv yuav tsum muaj tsawg kawg yog 2 qhov.

- Cov phaj kawg yuav tsum tau ua los ntawm cov khoom siv nrog qhov tsawg kawg nkaus elastic txwv ntawm 235 N / mm, thiab muaj a

Yam tsawg kawg nkaus thickness ntawm 6 hli rau cov khoom siv hauv chav kawm B, C & D.

- Nws yuav tsum muaj peev xwm kos cov voj voog hauv qab no ntawm cov phaj kawg: 110mm txoj kab uas hla rau chav kawm B props;

120mm rau cov khoom siv hauv cov chav kawm siab dua. Lub kaum sab xis yuav tsum tau muab sib dhos, tuav lub vojvoog ntawm 5

thiab 10mm.
