Lub tes tsho Rebar yog dav siv nyob rau hauv steel bar kev twb kev txuas nyob rau hauv ntau yam vaj tse xws li kev lag luam thiab pej xeem vaj tse, kev txuag dej, hluav taws xob fais fab, tunnels, txuas hniav, thiab lwm yam. Cov khoom yog txhim khu kev qha zoo nyob rau hauv engineering daim ntaub ntawv.
Lub steel bar connector yog ib qho sib npaug-lub zog sib koom ua ke uas nws lub zog yog siab dua lub zog ntawm steel bar puag cov khoom txuas nrog. Nws yog ib hom tshiab ntawm mechanical steel bar sib koom ua ke uas muaj zog thiab ceev. Nws cov khoom siv raw yog ua los ntawm seamless steel kav.
Cov qauv rau steel yeeb nkab ncaj threaded steel bar tes tsho yog raws li nram no:
1. Xaiv lub tes tsho threaded
1.1 Rebar kev sib txuas tau muab faib ua ob pawg: kev sib txuas lashing thiab cov khoom siv sib txuas lossis vuam. Mechanical kev sib txuas yog nyiam.
1.2 Cov kev sib txuas ntawm longitudinal stress-bearing bars nyob rau hauv txhua kab yog tag nrho mechanically txuas los yog welded.
1.3 Tag nrho cov kev sib txuas rebar thaum txoj kab uas hla ntawm lub zog rebar yog d Ntau tshaj los yog sib npaug rau 22 yuav tsum tau mechanically txuas los yog welded.
2. Lub tes tsho extrusion kev twb kev txuas txoj kev yog ntxig rau qhov kawg ntawm qhov yuav tsum tau txuas rebar (yuav tsum tau ribbed rebar) rau hauv lub tes tsho tshwj xeeb steel, thiab siv ib tug extruder los compress lub tes tsho steel kom nws mus plastically deform. Cov neeg kho tshuab kev koom tes thiab nruj nruj ntawm lub tes tsho steel deformed thiab ribbed rebar paub txog kev sib txuas ntawm cov rebar. Txoj kev sib txuas no feem ntau yog siv rau qib II thiab qib III rebar (nrog rau cov khib nyiab kho cua sov) nrog txoj kab uas hla ntawm 16 mus rau 40 mm. Txoj kev ntawm radial tes tsho extrusion kev twb kev txuas yuav tsum ua raws li qhov yuav tsum tau ntawm "Technical Specifications rau Ribbed Rebar Tes Tsho Extrusion Connection" (JGJ108-96).
