Yuav xam cov peev txheej ntawm Scaffolding?

Muaj peb hom scaffolding thauj khoom:

1. Tuag Load / Static load

2. Nyob load / dynamic thauj

3. Cua load / ib puag ncig thauj khoom

Niaj hnub no, peb yuav tsom rau cov neeg tuag thiab cov thauj khoom muaj kev laij tawm ntawm scaffolding. Hauv qab no peb yuav qhia ob qho piv txwv rau koj.

Qauv Ib:

Yuav ua li cas xam cov neeg tuag muaj peev xwm ntawm Scaffolding? Muaj ib qho piv txwv ntawm cov neeg tuag suav cov duab kos duab rau koj qhov kev txiav txim siab. Scaffolding yeeb nkab / raj mis hnyav 4.5 kg ib meter li per BS en 39: 2001

1 daim ntawm 3m txuj ci = 14 kg.

1piece ntawm ntsia hlau Nkaus = 5 kg.

4 daim ntawm ledgers 40 kg / 2 = 20 kg.

4 daim ntawm transoms = 32 kg / 2 = 16 kg.

1 daim ntawm lub ntsej muag brace = 18 kg / 2 = 9 kg.

1piece ntawm kawg cam = 10 kg / 2 = 5 kg

5 daim ntawm 2.4m planks = 100 kg / 4 = 25 kg

Cov tuag muaj peev xwm yog lig 94 kg.

Qauv ob:

Yuav suav li cas los laij cov nyob uas muaj peev xwm ntawm Scaffolding?

1. Lub luag haujlwm scaffold: 225 kg / m2

2. Nruab Nrab Ua Haujlwm Scaffold: 450kg / m2

3. Hnyav-Dest-Duty Scaffold: 675 kg / m2

Thiab peb xaus lus tias cov muaj peev xwm thauj tau muaj sib npaug rau tus neeg ua haujlwm qhov hnyav ntxiv rau cov cuab yeej hnyav ntxiv. Kev nyab xeeb ua haujlwm ntawm Scaffolding (SWL) = Tuag Loading muaj peev xwm 4 zaug nyob thauj khoom muaj peev xwm.

Paffolding lub hnab ntim kev muaj peev xwm

Scaffolding hnab siv rau scaffolding cov ntaub ntawv nqa, hauv av rau nce. Feem ntau cov hnab scaffolding lub hnab ua los ntawm canvas, nws yog qhov tseem ceeb heev rau kev nqa scaffolding Cheebtsam thiab Scaffolding Spanner.

Lub peev xwm ntawm scaffolding lub hnab (SWL ntawm Scaffolding Hnab) yog los ntawm 30 kg mus rau 50 kg uas yog raug rau scaffolding lub hnab ntim lub cev.
