Ulwakhiwo lwensimbi yensimbi lulungelelaniswa kwiimfuno zeenjongo ezahlukeneyo. Isetyenziswe ngokubanzi kwiindibano zocweyo zoshishino kumashishini afana ne-smelters, i-steel rolling mills, ishishini lemichiza, ishishini lezemigodi kunye nezityalo zamandla njengamaqonga omgangatho, amaqonga, iindlela zokuhamba, izinyuko, njl. Owokuqala uthwala umthwalo, kwaye lo wokugqibela udibanisa yangaphambili ibe yigridi epheleleyo. Ngokwendlela yokudibanisa kunye neempawu zenkqubo ye-grating kunye nemivalo, i-steel grating ihlukaniswe kwiindidi ezininzi.
Uxinzelelo welded steel grating
Uxinzelelo oludityanisiweyo lwegrayiti lwenziwe ngegrayiti ethwele umthwalo wexesha elide kunye nentsimbi ejijekileyo ejijekileyo, ngoncedo lonikezelo lwamandla welding ngaphezulu kwe-2000KV kunye noxinzelelo lwe-100t. Ububanzi bemveliso yi-1000mm. Igrayiti yayo ethwele umthwalo ayinayo imingxunya yokugqobhoza (oko kukuthi, ayenzi buthathaka). Iingqokelela kwizalathiso zelongitudinal kunye nezinqamlezileyo zidityaniselwe inqaku ngenqaku. Iiwelds zigudileyo kwaye azinaslag, ngaloo ndlela zenza igridi enama-600 ukuya kwi-1000 iindawo zoqhagamshelo eziqinileyo kwi-square meter, ezinokuhanjiswa kokukhanya okufanayo kunye nokungena komoya. Ekubeni i-welding point ayinayo i-slag, inokubambelela kakuhle kwipeyinti okanye i-galvanized layer, njengoko kuboniswe kuMzobo 1. I-T-joint phakathi kwegridi yokuphela kwayo kunye negridi ethwala imithwalo ixhunywe yi-CO2 yegesi ekhuselekileyo.
Uxinzelelo olufakwe kwi-welded steel grating
Iqukethe igridi ethwele umthwalo kunye nomngxuma otyhoboziweyo kunye negridi enqamlezileyo ngaphandle komngxuma ophothiweyo. Igridi enqamlezileyo ifakwe kwigridi ethwele umthwalo, kwaye emva koko umatshini woxinzelelo lwe-welding usetyenziselwa ukudibanisa i-node nganye. Ekubeni ifana nesakhiwo segridi yangaphambili, kodwa igridi eguquguqukayo yiplate, i-modulus yecandelo layo likhulu kuneyentsimbi ephothiweyo yesikwere, ngoko inomthwalo ophezulu wokuthwala umthwalo kunegridi yangaphambili.
I-shed ethwele umthwalo weplate yensimbi ecinezelweyo ifakwe ukudibanisa imivalo. Indawo yokubeka imile okwerhengqa. Iindawo zokubeka ezimile okwerhengqa zeepleyiti zegrayiti ezithwele umthwalo ezikufutshane zigotshwe kumacala achaseneyo. Imivalo eguquguqukayo engabonakaliyo iqhutywe kwiindawo zokubeka iiplati ezithwala umthwalo kunye noxinzelelo oluphezulu ngomshini okhethekileyo. Ekubeni i-slots igobile kwicala elichaseneyo, imivalo enqamlezileyo yongezwa kunye nomlinganiselo owongezelelweyo, okwandisa ukuqina kweplate ye-grating. Ngoko ke, iipleyiti ezithwele umthwalo kunye nemivalo enqamlezileyo idityaniswe ngokungafaniyo enye kwenye, zenza ipleyiti eqinile yokukrala enokumelana ne-horizontal shear force kwaye inobunzima obukhulu be-torsional, ukuze ikwazi ukumelana nomthwalo omkhulu. I-node efana ne-T phakathi kwepleyiti yokuphela komphetho wepleyiti ecinezelweyo kunye nepleyiti ethwele umthwalo idityaniswe ne-CO2 yegesi ekhuselweyo.
Iplagi yokucoca intsimbi yentsimbi Olu hlobo lwepleyiti yegrayiti lune-slender slot kwipleyiti ethwele umthwalo. Imivalo ifakwe kwi-slots kwaye ijikelezwe ukwenza igridi ethe nkqo kunye nethe tye kwinotshi. Isiphelo somphetho wepleyiti yepleyiti ethwele umthwalo idityaniswe kunye nepleyiti ethwele umthwalo nge-CO2 yegesi ekhuselweyo. Ukongezelela, imivalo iqiniswa ngeebhloko emva kokulungiswa. Olu hlobo lwepleyiti yegrayiti luveliswe ngobuninzi eTshayina. Iingenelo zayo ziyindibano elula kunye nomthwalo ongaphantsi kwe-welding, kodwa umthamo wayo wokuthwala awukho phezulu, ngoko unokusetyenziswa kuphela njengeplate yokugaya ukukhanya.
I-Sawtooth ipleyiti ekhethekileyo ye-grating Xa kukho iimfuno ezikhethekileyo ezichasene ne-skid kwi-grating plate, njengeendlela ezithambekileyo ezinomkhenkce, ikhephu okanye ioli, i-sawtooth iplate ekhethekileyo yokugaya ingasetyenziswa. Olu hlobo lwe-grating plate luneentlobo ezimbini: eziqhelekileyo kunye nezikhethekileyo. Ipleyiti yayo ethwele umthwalo yi-slat ene-serration. Imivalo yokugaya i-transverse iyafana naleyo ye-pressure-welded grating plate, eziziintsimbi eziphothiweyo zesikwere ezinoxinzelelo-welding kwi-plate-bearing grating plate. Xa umsebenzisi eyidinga, ukwenzela ukuthintela ibhola ye-15mm ububanzi okanye ezinye izinto zobukhulu obufanayo ukuba zidlule kwi-gap, enye okanye ngaphezulu kweentsimbi zetsimbi ezinentambo zinokuthi zibe noxinzelelo-welding phakathi kweepleyiti ezijongene nomthwalo ophantsi kweentsimbi ezinqamlezileyo zokugaya (intsimbi ephothiweyo yesikwere). Umahluko phakathi kohlobo oluqhelekileyo lwepleyiti yegrayiti kunye nepleyiti yodidi olukhethekileyo lolokuba uhlobo oluqhelekileyo lwemivalo yegrayiti enqamlezileyo idityaniswe kwincam engaphezulu yeeserrations zeplate ethwele umthwalo. Ngale ndlela, iinyawo zabantu baqhagamshelane kuphela imivalo ezinqamlezayo (Figure 5a), lo gama imivalo ezinqamlezayo-ezimilise ezikhethekileyo ezidityanisiweyo kwi emkhombeni ye-sawtooth ipleyiti igridi ethwele umthwalo, ukuze iinyawo zabantu ziya kuqhagamshelana isarha (Figure 5b). Ngoko ke, uhlobo olukhethekileyo lunokumelana okukhulu ne-anti-slip kunohlobo oluqhelekileyo. Xa kuthelekiswa nohlobo oluqhelekileyo, le yokugqibela inama-45% amandla amakhulu okuchasa ukutyibilika kwindlela yebha enqamlezileyo kuneyangaphambili.
Kungakhathaliseki ukuba luhlobo luni na, kuba ludibaniso lwegridi yeplate yegridi kunye nemivalo, inomsebenzi ogqwesileyo wokulwa ne-slip kunye nomthamo oqinileyo wokuthwala. Ukongezelela, iimveliso zayo ezigqityiweyo azikho izithuba kwaye azikho imingxuma yokubhoboza. Ukuba umphezulu unikwe imilinganiselo yokukhusela i-galvanized, ukuxhathisa kwayo kwe-corrosion kunye nokumelana nokunxiba kuphezulu kakhulu kunenye i-metal decking. Ukongeza, ukuhanjiswa kwayo kokukhanya okuhle kunye nokungena komoya kwakhona kumisela ukuba kufanelekile kwiimeko ezahlukeneyo.
