1, Terminology thiab cov ntsiab lus rau welded steel mesh
Cov hlau mesh tsim los ntawm vertically arranging longitudinal thiab transverse steel tuav nrog tib los yog sib txawv diameters ntawm ib tug tej qhov chaw, thiab qhov chaw welding tag nrho cov ntsiab lus sib tshuam ua ke yog hu ua steel welded mesh. Hlau reinforcement welding thiab mesh tuaj yeem muab faib ua peb hom raws li cov ntaub ntawv: txias dov ribbed steel reinforcement welding mesh, kub dov ribbed steel reinforcement welding mesh, thiab txias drawn thiab dov du steel reinforcement welding mesh. Tam sim no, txoj hauv kev thiab ntau hom ob qho tib si hauv tsev thiab thoob ntiaj teb yog cov welded mesh ntawm txias-dov ribbed steel tuav.
Lub longitudinal thiab transverse cov lus qhia ntawm steel welded mesh yog txiav txim los ntawm kev tsim khoom. Feem ntau hais lus, cov hlau tuav tau teem rau tib lub sijhawm rau kev tsim khoom ntawm cov hlau welded mesh yog longitudinal steel tuav, thiab cov hlau tuav tau teem rau perpendicular rau kev tsim khoom ntawm cov hlau welded mesh yog transverse steel tuav. Nws tsis tuaj yeem nkag siab zoo li cov kab hlau ntev ntev nyob rau hauv qhov ntev sab kev taw qhia thiab transverse steel tuav nyob rau hauv luv sab kev taw qhia. Ob txoj kab ntawm tib hom thiab txoj kab uas hla uas txuas nrog ib sab ntawm lub welded steel mesh yog hu ua parallel tuav thiab tsuas yog siv rau longitudinal steel tuav.
Qhov ntev ntawm sab ntev ntawm cov hlau welded mesh yog qhov ntev ntawm lub mesh, thiab qhov ntev ntawm sab luv ntawm lub dav hlau ntawm cov hlau welded mesh yog qhov dav ntawm lub mesh. Lawv muaj kev ywj pheej ntawm cov kev taw qhia ntawm kev tsim cov hlau welded mesh, thiab yuav tsum tsis txhob totaub nrog kev faib cov longitudinal thiab transverse tuav ntawm steel welded mesh.
Hlau reinforcement welded mesh tuaj yeem muab faib ua hauv qab mesh thiab nto mesh raws li qhov sib txawv paving txoj hauj lwm, thiab nto mesh tuaj yeem muab faib ntxiv rau hauv kev txhawb nqa nto mesh, longitudinal thiab transverse nto mesh, thiab kub nto mesh. Raws li kev tsim khoom sib txawv thiab kev muab khoom, nws tuaj yeem muab faib ua customized steel welded mesh thiab standardized steel welded mesh.
Steel reinforcement welded mesh yog feem ntau tsim nyob rau hauv lub Hoobkas, thiab steel reinforcement hloov tsim yog nqa tawm raws li tus tsim drawings. Nws tsuas yog siv tau rau kev tsim kho engineering tom qab tau lees paub los ntawm lub koom haum tsim thiab tshuaj xyuas.
2, Technical indicators, As thiab kev tsim kho ntawm welded steel mesh
1. Technical parameters
Tus qauv lub zog tus nqi rau txias-dov ribbed steel tuav thiab txias drawn (dov) du steel tuav yog 550 Newton / square millimeter; Tus tsim lub zog tus nqi ntawm txias-dov ribbed steel tuav yog 360 Newton / square millimeter.
Tus qauv lub zog tus nqi ntawm kub-kub Qib I puag ncig steel tuav yog 370 Newton / square millimeter; Tus tsim lub zog tus nqi ntawm kub-kub Qib I puag ncig steel tuav yog 210 Newton / square millimeter;
Tus qauv lub zog muaj nuj nqis rau kub-kub qib II thiab III ribbed steel tuav yog 490 Newton / square millimeter thiab 570 Newton / square millimeter, feem. Tus tsim lub zog muaj nuj nqis rau kub dov qib II thiab III ribbed steel tuav yog 300 Newton / square millimeter thiab 360 Newton / square millimeter.
Raws li qhov yuav tsum tau hloov qhov sib npaug ntawm lub zog steel tuav, kev tsim kho txheej txheem ntawm kev siv txias-kuav los tiag ribbed steel bar welded mesh rau cam khwb cia-hauv-qhov chaw hauv pem teb slabs nyob rau hauv vaj tse engineering yuav txuag tau steel noj.
2. Anchorage xav tau
Nyob rau hauv lub cam khwb cia-nyob rau hauv-qhov chaw qauv ntawm lub tsev nyob rau hauv pem teb slab pob zeb, lub steel reinforcement nyob rau hauv lub kawg ntawm lub mesh txuas mus rau hauv lub beam los yog kev txhawb pab raws li ib tug taag kev twb kev txuas. Thaum lub sij hawm installation, nws yog tsim nyog los xyuas kom meej txaus anchoring ntev, tshwj xeeb tshaj yog rau cov nto mesh ntawm qab mesh thiab sab span.
3. Lapping xav tau
Hauv cov khoom ua vaj tse, thaum qhov ntev lossis qhov dav ntawm cov welded steel mesh tsis txaus, qhov kev sib txuas tsim los ntawm kev sib tshooj lossis embedding ob daim mesh raws li qee qhov tshwj xeeb hu ua welded steel mesh overlap. Qhov kev ncua deb ntawm qhov sib tshooj kawg ntawm ob lub hlau welded mesh daim (ribbed steel welded mesh) los yog qhov kev ncua deb ntawm lub sab nraud transverse steel tuav ntawm ob steel welded mesh daim (steel welded mesh) yog qhov sib tshooj ntev ntawm cov hlau welded mesh.
Muaj peb hom kev sib tshooj rau welded steel mesh. Ib qho yog txoj kev stacking: nws yog txoj kev sib tshooj ntawm stacking ib mesh rau lwm mesh. Feem ntau siv rau ib-txoj kev board mesh paving. Txoj kev thib ob yog txoj kev sib cuam tshuam: nws yog muab ib lub mesh rau ntawm lwm lub mesh, kom cov kab rov tav steel tuav nyob rau hauv tib lub dav hlau, thiab ntsug steel tuav yog overlapped nyob rau hauv ob lub dav hlau sib txawv. Feem ntau siv rau paving ntawm welded steel mesh nyob rau hauv thinner pob zeb slabs. Qhov thib peb yog txoj kev sib tshooj tiaj tus: nws yog ib txoj hauv kev ntawm embedding steel tuav ntawm ib lub mesh mus rau lwm lub mesh, kom cov longitudinal thiab transverse steel tuav ntawm ob lub mesh yog feem nyob rau hauv tib lub dav hlau. Feem ntau siv rau saum npoo mesh faib qhov cuab lub zog ntawm pem teb slabs, av tawg tiv thaiv nets, thiab tsis zoo dabtsi yog khoov lub sij hawm steel tuav.
Peb daim ntawv sib tshooj ntawm cov hlau welded mesh yuav tsum ua raws li plaub yam hauv qab no: tag nrho cov hlau tuav ntawm ob daim mesh yuav tsum ua kom tiav ntawm tib qhov sib tshooj; Qhov thib ob, cov chaw sib tshooj yog tag nrho khi nrog cov hlau hlau; Qhov thib ob, lub thickness ntawm cov txheej tiv thaiv nyob rau hauv lub overlapping cheeb tsam tom qab paving yuav tsum ua raws li cov specifications; Qhov chaw sib tshooj yuav tsum tau teeb tsa tib yam, thiab cov pob qij txha sib tshooj yuav tsum tau teeb tsa ntawm qhov tsawg kawg nkaus lub sijhawm khoov.
Muaj peb hom kev sib tshooj rau welded steel mesh: ua ntej, qhov sib tshooj ntev yuav tsum muaj rau txhua txoj kev sib tshooj sib txawv; Qhov thib ob yog tias cov ntaub ntawv sib tshooj dav hlau sib txawv; Qhov thib peb yog vim li cas tus naj npawb ntawm cov hlau tuav tau pom nyob rau sab saum toj saib yog txawv, nrog 2 txheej ntawm steel tuav nyob rau hauv lub tiaj tiaj tiaj txoj kev, 3 txheej ntawm steel tuav nyob rau hauv lub buckle lap txoj kev, thiab 4 txheej ntawm steel tuav nyob rau hauv lub ca. stacked txoj kev.
