Izinto okufanele ziqaphele lapho kusungulwa imichilo ye-portal

Ukuphakama kwe-portalukugoqa: Okwe-portal scaffolding, imininingwane engu-5.3.7 no-5.3.8 show ukuthi ukuphakama kwangaphandle kwe-tube ye-tube kuvame ukungadluli ama-50m. Lapho ukuphakama kohlaka kudlula i-50m, izigxobo zeshubhu eziphindwe kabili zingasetshenziswa. noma ukulayisha okuhlukanisiwe nezinye izindlela ukuhlinzeka ngesiqinisekiso sobuchwepheshe, futhi kufanele kuklanywe ngokwahlukile. Ngakho-ke, ngaphansi kwezindlela zokulayisha ezinengqondo, ukuvalwa kwepayipi kwensimbi yensimbi emangalweni kungakhiwa ngaphezulu, ngisho nangaphezulu kwama-80m; Kepha, uma ukuphakama kwe-Erection kudlula ama-50m, ukutshala imali kwesikhathi kukhulu kakhulu futhi akunakubiza. Indlela ye-Cantilever Erectional ehlukanisiwe ivame ukusetshenziswa.

Izinto okufanele ziqaphele lapho kusungulwa imichilo ye-portal

1. Ukulandelana kwe-erection of the scaffolding: Faka isisekelo. Isinyathelo sokuqala ukufaka uhlaka esisekelweni. Faka i-Shear Brace, beka i-pedal yezinyawo (noma uhlaka oluhambisanayo), faka i-Barge Core, bese ufaka isinyathelo esedlule. Faka uhlaka lomnyango bese ufaka ingalo yokukhiya.

3. Faka isisekelo ngokuya ngesikhundla esimakwe ku-pad (noma pad) bese ufaka amafreyimu amabili emnyango esitezi sokuqala. Bese ufake i-Cross brace bese ukhiya ukhiye ukuze uqinisekise ukuqina kohlaka lomnyango olufakiwe.

4. Setha i-gantry eyalandela ngokulandelana; Nge-gantry ngayinye, faka i-shear brace Khiya ucezu lokukhiya, bese ulungisa isisekelo ngezipikili ukuvikela ukushelela.

6. Faka izingalo zokukhiya ezihlalweni zokukhiya emaphethelweni aphezulu we-mast ngokulandelana. Ukuqondiswa kweziloya kufanele kube njalo ukuthi elinye ukuphela liya phezulu futhi ligobekile ngendlela efanayo. Musa ukuya endaweni engafanele ukugwema ukungakwazi ukusebenzisa endaweni lapho uxhuma ku-mast esinyathelweni esedlule.

7. Ngemuva kwesinyathelo sokuqala se-gantry scaffolding sakhiwe, isinyathelo sesibili sokuqashwa singasungulwa kusukela ekupheleni kwesinyathelo sokuqala sokuqabula ukuvimbela ukuxhumeka emaphutheni.

8. Lapho ehlukanisa uhlobo lwe-gantry-hlobo-scaffolding phezulu, umkhathi wensimbi kufanele ufakwe ngasikhathi sinye esimweni esibekiwe. Isiphetho esingezansi sesinyathelo sensimbi esingezansi kufanele silungiswe ngepayipi lensimbi.

9. Kulo lonke uhlobo lwe-ganry-uhlobo Scaffolding, izinduku zokuqinisa okuvundlile kanye nezinduku zokuqinisa ukuwela kufanele zengezwe ukukhulisa ukuqina. Izinduku ezivundlile nezesiphambameze zenziwe ngamapayipi ensimbi futhi zixhunywe ngokuqondile ku-mast nge-fasteners. I-angle phakathi kwenduku yokuqinisa i-cross-restforment nenduku ethe mpo kufanele ibe ngu-45 °.

10. Lapho uhlela uhlobo lwe-gantry-hlobo lukhuni, inetha lokuphepha elingaphandle kumele lifakwe ngokufanele.

11. Ngemuva kokuthi amafreyimu okuqala eminyango emine ahlelwe nge-shear braces, izinyawo zezinyawo noma ozimele ezivundlile zifakiwe, bese kuthi amafreyimu e-hook anded kuwo womabili ama-Emps kufanele akhiywe njengoba efakiwe.
