Isingeniso somkhiqizo
Uhlaka lokusekela lusetshenziselwa ukuxhuma imigqa eminingi yama-trusses ukuze kuqinisekiswe ukuzinza namandla afanayo eyunithi ye-bridge truss.Uhlaka lokusekela lungaxhunywa phezulu kwechord engenhla noma induku eqondile.
Kukhona amafreyimu ayisithupha ajwayelekile okusekela (aziwa nangokuthi amafreyimu ezimbali, amafasitela ezimbali);
Uhlobo lwe-321 luvame kakhulu: uhlaka lokusekela lwe-450, uhlaka lokusekela lwe-900, uhlaka lokusekela lwe-1350;
200 uhlobo ngokuvamile: 480 uhlaka oluvundlile ukwesekwa, 480 uhlaka losekelo mpo, 730 uhlaka oluvundlile ukweseka, 730 uhlaka ukwesekwa mpo.
Uhlaka lokusekela lumi kanje: ifreyimu yokusekela isetshenziselwa ukuxhuma umugqa wokuqala kanye nomugqa wesibili wama-trusses.Ibhuloho lensimbi le-Bailey elinemigqa emibili, enkabeni yendawo engaphezulu ye-truss ngayinye (noma i-chord eqinisiwe), uhlaka lokusekela lufakwa ngokuvundlile.Endabeni yemigqa ephindwe kabili kanye nezendlalelo eziphindwe kabili, ngaphezu kokufaka ifreyimu yokusekela phezulu, uhlaka lokusekela kufanele lufakwe endongeni yangemuva eqondile ye-truss engenhla (induku eyodwa eqondile ekugcineni kwesigaba sokuqala se-truss kufanele futhi ifakwe).Uma umisa ibhuloho elinemigqa emithathu, indawo nenombolo yozimele bokusekela kuyafana nalezo zebhuloho elinemigqa emibili.Lapho ufaka, faka imikhono egobile engu-4 emikhawulweni yomibili emigodini yohlaka yokusekela yemigqa emibili yama-trusses, bese uyilungisa ngamabhawodi okusekela.
Emabhulohweni edekhi, iningi losayizi wefreyimu yokusekela yi-900 noma i-1350, futhi kukhona nezinhlelo ezikhethekile zokuxhuma izinduku ngokuya ngezidingo, futhi eziningi zazo zifakwe ngamabhawodi okusekela.
imininingwane yomkhiqizo
Isicelo somkhiqizo
I-angle yensimbi isetshenziswa kabanzi esakhiweni sesakhiwo esihlukahlukene kanye nesakhiwo sobunjiniyela.
1.ugongolo, amabhuloho, ukwakhiwa, umbhoshongo wezokuxhumana, umkhumbi.
2.umbhoshongo wokudlulisa, umbhoshongo wokusabela, amashalofu ezimpahla ze-warehouse, njll.
3.ukuphakamisa imishini yokuthutha,ukwenza umshini wezolimo.
4.isithando somlilo sezimboni.
5.uhlaka lwesiqukathi.
