Cov qauv steel grating yog yoog raws li qhov xav tau ntawm ntau lub hom phiaj. Nws tau siv dav hauv kev cob qhia kev lag luam hauv kev lag luam xws li smelters, steel dov mills, tshuaj lom neeg kev lag luam, kev lag luam mining thiab fais fab nroj tsuag li pem teb platforms, platforms, sidewalks, stair stairs, thiab lwm yam. Cov hlau grating muaj longitudinal gratings thiab transverse tuav. Tus qub bears lub load, thiab tom kawg txuas tus qub rau hauv ib daim phiaj zoo li tag nrho. Raws li txoj kev sib txuas thiab cov txheej txheem cov yam ntxwv ntawm cov grating thiab cov tuav, steel grating muab faib ua ntau hom.
Siab welded steel grating
Lub siab welded grating yog ua los ntawm longitudinal load-bearing gratings thiab transverse twisted square steel, nrog kev pab los ntawm vuam fais fab mov saum 2000KV thiab 100t siab. Qhov dav dav yog 1000mm. Nws load-bearing grating tsis muaj qhov punching (piv txwv li, nws tsis muaj zog). Cov nodes nyob rau hauv longitudinal thiab transverse cov lus qhia yog welded point los ntawm point. Cov welds yog du thiab slag-dawb, yog li tsim ib daim phiaj nrog 600 mus rau 1000 ruaj khov kev sib txuas ntawm ib square meter, uas muaj teeb pom kev zoo sib kis thiab huab cua permeability. Txij li thaum lub vuam taw tes tsis muaj slag, nws muaj zoo adhesion rau xim los yog galvanized txheej, raws li qhia nyob rau hauv daim duab 1. T-joint ntawm nws kawg daim phiaj thiab lub load-bearing kab sib txuas nrog CO2 roj shielded vuam.
Embedded siab welded steel grating
Nws muaj cov kab hluav taws xob thauj khoom nrog lub qhov punched thiab ib daim phiaj hla tsis muaj qhov punched. Lub transverse kab sib chaws yog embedded nyob rau hauv lub load-bearing daim phiaj, thiab ces lub siab welding tshuab yog siv los welding txhua node. Txij li thaum nws zoo ib yam li cov qauv kab sib chaws dhau los, tab sis cov kab sib chaws transverse yog ib lub phaj, nws cov seem modulus yog ntau dua li cov twisted square steel, yog li nws muaj peev xwm ntau dua li cov kab sib chaws dhau los.
Lub load-bearing shed ntawm nias steel grating phaj yog slotted rau kev sib txuas ntawm cov tuav. Lub qhov yog mob-zoo li tus. Cov kab mob zoo li qhov ntawm cov kab mob uas nyob ib sab uas nyob ib sab yog khoov rau hauv cov lus qhia. Cov kab uas tsis muaj zog tsis muaj zog tau raug thawb mus rau hauv qhov chaw ntawm cov kabmob load-bearing grating daim hlau nrog kev kub siab los ntawm cov xovxwm tshwj xeeb. Txij li thaum cov slots yog khoov nyob rau hauv opposite lus qhia, lub transverse tuav yog ntxiv nrog ib tug ntxiv dimension, uas ua rau kom lub rigidity ntawm lub grating phaj. Yog li ntawd, lub load-bearing grating daim hlau thiab transverse tuav yog inextricably txuas rau ib leeg, tsim ib tug muaj zog grating phaj uas muaj peev xwm tiv taus kab rov tav shear quab yuam thiab muaj zoo torsional rigidity, thiaj li hais tias nws muaj peev xwm tiv taus ib tug loj load. T-shaped node nruab nrab ntawm qhov kawg ntug phaj ntawm lub phaj nias thiab cov kabmob load-grating phaj yog welded nrog CO2 roj shielded vuam.
Plug-in steel grating phaj Hom grating phaj no muaj ib lub qhov me me ntawm cov kabmob load-bearing grating phaj. Cov tuav tau muab tso rau hauv qhov qhib thiab tig los ua ib daim phiaj ntsug thiab kab rov tav hauv qhov thais. Qhov kawg ntug phaj ntawm load-bearing grating phaj yog welded nrog lub load-bearing grating phaj los ntawm CO2 roj shielded vuam. Tsis tas li ntawd, cov tuav tau txhawb nqa nrog cov blocks tom qab kho. Hom grating phaj no tau tsim ntau hauv Suav teb. Nws qhov zoo yog kev sib dhos yooj yim thiab tsawg dua vuam ua haujlwm, tab sis nws lub peev xwm thauj khoom tsis siab, yog li nws tsuas yog siv tau los ua lub teeb grating phaj.
Sawtooth tshwj xeeb grating phaj Thaum muaj qhov tshwj xeeb los tiv thaiv kev sib tsoo rau cov phaj grating, xws li inclined sidewalks nrog dej khov, daus los yog roj, sawtooth tshwj xeeb grating phaj siv tau. Hom grating phaj no muaj ob hom: zoo tib yam thiab tshwj xeeb. Nws load-bearing grating phaj yog slat nrog serrations. Lub transverse grating tuav yog tib yam li cov siab-welded grating phaj, uas yog twisted square steels uas yog siab-welded rau load-bearing grating phaj. Thaum tus neeg siv xav tau nws, txhawm rau tiv thaiv 15 hli txoj kab uas hla lub pob lossis lwm yam khoom loj sib xws los ntawm qhov sib txawv, ib lossis ntau dua threaded steel tuav tuaj yeem ua kom siab-welded ntawm cov kab uas nyob ib sab load-bearing grating daim hlau nyob rau hauv lub transverse grating tuav (twisted square steel). Qhov sib txawv ntawm hom zoo tib yam serrated grating phaj thiab tshwj xeeb hom grating phaj yog tias hom zoo tib yam ntawm transverse grating tuav yog welded mus rau sab sauv kawg ntawm cov serrations ntawm load-bearing grating phaj. Nyob rau hauv txoj kev no, cov hneev taw ntawm tib neeg tsuas yog hu rau cov kab hla hla (Daim duab 5a), thaum cov khoom tshwj xeeb zoo li cov hlaws hlais yog welded rau lub trough ntawm sawtooth ntawm daim phiaj load-bearing daim phiaj, yog li cov hneev taw ntawm tib neeg yuav hu rau sawtooth (Daim duab 5b). Yog li ntawd, hom tshwj xeeb muaj ntau dua los tiv thaiv plam ntau dua li hom zoo tib yam. Piv nrog rau hom zoo tib yam, tom kawg muaj 45% muaj peev xwm los tiv thaiv plam hauv qhov kev taw qhia bar hla dhau qhov qub.
Txawm li cas los xij, vim tias nws yog kab sib txuas ntawm daim phiaj phaj thiab cov tuav, nws muaj kev ua haujlwm zoo los tiv thaiv plam thiab muaj zog muaj peev xwm. Tsis tas li ntawd, nws cov khoom tiav tsis muaj qhov khoob thiab tsis muaj qhov punching. Yog hais tias qhov saum npoo tau muab kev tiv thaiv galvanized, nws cov kev tiv thaiv corrosion thiab hnav tsis kam yog qhov zoo tshaj rau lwm cov hlau decking. Tsis tas li ntawd, nws lub teeb kis tau zoo thiab huab cua permeability kuj txiav txim siab tias nws tsim nyog rau ntau lub sijhawm.
