Ntawm cov chaw tsim kho, scaffolding ua haujlwm ua lub hauv paus tseem ceeb rau kev ua haujlwm ntawm qhov siab, thiab nws qhov kev lees txais zoo txiav txim siab ncaj qha rau kev nyab xeeb ntawm kev tsim kho thiab kev nce qib ntawm qhov project.

I. Cov Qauv Tseem Ceeb: Cov Kev Txwv Ruaj Khoov ntawm Kev Xam Xaj Txog Kev Tshawb Fawb

1. Cov txheej txheem scaffolding: Qhov nrug ntsug ntawm cov uprights ≤ 2m, qhov nrug kab rov tav ≤ 1.5m (JGJ130 Rooj 6.1.1-1), qhov nrug ntsug ntawm cov tswv cuab kab rov tav ≤ 1.8m, qhov nrug ntawm cov tswv cuab kab rov tav transverse ≤ 2m.
Kev tshawb fawb txog rooj plaub: Hauv ib qho project, qhov sib nrug ntawm cov uprights tshaj 10%, ua rau 35% txo qis hauv qhov kev nruj ntawm cov qauv scaffolding, uas thaum kawg ua rau tilting raws li cua ntsawj.

II. Kev Ntsug Ntawm Cov Ncej Sawv Ntsug: Kev Tswj Xyuas Qhov Tseeb Qib Millimeter

Thaum kuaj xyuas qhov ntsug ntawm cov ncej ncaj, muaj cov nqi sib txawv uas tso cai meej meej ntawm ntau theem, sib xws rau cov cuab yeej tshuaj xyuas tshwj xeeb. Tshwj xeeb:

1. Rau txhua 1m ntawm qhov siab ntawm tus ncej ntsug, qhov sib txawv uas tso cai yog ± 2 hli, ntsuas siv lub theodolite lossis kab plumb.

2. Thaum qhov siab tag nrho ntawm lub scaffolding tsawg dua lossis sib npaug rau 30m, qhov kev hloov pauv tso cai yog ± 50mm, kuj ntsuas siv theodolite lossis plumb line.

3. Yog tias qhov siab tag nrho ntawm lub scaffolding ntau dua 30m, qhov kev hloov pauv tso cai yog ± 75mm, thiab cov cuab yeej tshuaj xyuas tseem yog theodolite lossis plumb kab.

Raws li cov ntaub ntawv ntsuas tiag tiag, hauv ib qhov project, qhov kev hloov pauv ntawm cov ncej ntsug tau dhau qhov txwv los ntawm 20%, ua rau muaj kev nce ntxiv 1.8 npaug ntawm kev hloov pauv sab ntawm cov qauv scaffolding. Qhov xwm txheej no ua rau muaj kev phom sij rau kev nyab xeeb heev.

III. Kev Teeb tsa Cov Qws Me Me Kab Rov Tav: Cov Nodes Tseem Ceeb rau Kev Hloov Chaw Thauj Khoom

1. Cov Kev Cai Tsim Kho Node: Cov hlua khi me me yuav tsum tau txuas nrog cov ncej ntsug siv cov couplers sab xis. Tus nqi torque ntawm node yuav tsum ncav cuag 40-65 N·m (JGJ130 Rooj 4.3.5). Yuav tsum ntxiv ib qho hlua khi me me ntxiv rau hauv qab cov ntoo scaffolding ntawm lub platform ua haujlwm, tsim kom muaj "peb-bar txhawb nqa", uas tuaj yeem txo qhov hnyav ib qho los ntawm 40%.

2. Kev Txuas:
Qhov ntev ntawm cov kab rov tav me me yuav tsum tau tswj kom tsis pub dhau 100-150 hli (JGJ130 Daim Duab 6.2.2). Qhov ntev dhau tuaj yeem ua rau lub zog khoov dhau qhov txwv.

IV. Kev Tswj Xyuas Cov Khoom Siv: Cov Lus Qhia Txog Kev Ua Tau Zoo

1. Kev Tshuaj Xyuas Khoom Siv: Cov khoom siv khi yuav tsum tsis muaj qhov tawg thiab qhov hws. Yuav tsum tau kuaj xyuas 100%, nrog rau kev kuaj xyuas kev ua haujlwm tiv thaiv kev plam (P≥8kN). Yog tias tus nqi tsis lees txais tshaj 5%, tag nrho cov khoom yuav raug xa rov qab.

2. Cov Lus Qhia Txog Kev Siv: Cov khoom siv sib txuas uas muaj lub kaum sab xis yog siv rau kev sib txuas ntsug, thiab cov khoom siv sib hloov tau yog siv rau kev sib txuas uas tsis yog ntsug. Txwv tsis pub sib xyaw ntau hom khoom siv sib txawv. Cov khoom siv sib txuas uas muaj xeb tob dua 0.3 hli yuav tsum tau muab pov tseg.

Xaus Lus: Kev ntsuam xyuas kev lees txais yog kab kawg ntawm kev tiv thaiv rau kev nyab xeeb. Kev ntsuam xyuas kev lees txais scaffolding yuav tsum tau tsim kom muaj "kev tshuaj xyuas peb theem thiab kev txheeb xyuas peb theem" ​​system: pab pawg neeg tus kheej tshuaj xyuas, rov tshuaj xyuas qhov project, thiab kev tshuaj xyuas tshwj xeeb ntawm lub tuam txhab; kev txheeb xyuas cov ntawv xam, kev txheeb xyuas cov khoom sib xyaw, thiab kev txheeb xyuas cov qauv sib koom ua ke. Yuav tsum tau them sai sai rau kev saib xyuas ntxiv ntawm kev sib sau ua ke ntawm scaffolding thaum lub caij los nag (ib zaug ib hnub, nrog qhov kev hloov pauv ntawm ≤10mm).

Ceeb Toom Txog Kev Lag Luam: Ib qho chaw ua haujlwm tau muaj ib feem ntawm cov scaffolding vau vim tsis tau hloov cov fasteners uas xeb, ua rau peb tus neeg raug mob hnyav. Qhov xwm txheej no qhia ncaj qha txog qhov teeb meem tseem ceeb ntawm cov txheej txheem kuaj kev lees txais sab nraud.
