Steel Channel - ib qho ntawm ntau hom dov hlau

Tej kev tsim kho (industrial los yog civil) yog teb tsis coj mus siv ib tug loj tus naj npawb ntawm ntau kho vajtse (hlau khoom) uas yuav tsum muaj ntaub ntawv raws li fastening pab kiag li lawm, thiab raws li ib feem ntawm cov yam ntxwv kev pab txhawb nqa neeg. Feem ntau, qhov kho vajtse yog tsim los ntawm ntau hom steel (tsuas yog cov qis qis), thiab cov neeg nyiam tshaj plaws ntawm lawv yog cov khoom tsim los ntawm cov hlau, tshwj xeeb tshaj yog cov qauv hauv tsev. Lub tsev profiles muaj xws li cov khoom xws li kab teeb, hom, I-beams, raws, fab, thiab lwm yam.

Nyob rau hauv tsab xov xwm no peb yuav tham txog cov cai, uas yog siv ntau yam lag luam, ob qho tag nrho kev lag luam thiab kev tsim kho.

Lub tswvyim ntawm txoj haujlwm

Nqaj raws (channel steel) yog hu ua ib tug nqaj uas muaj ib tug U-zoo li tus ntoo khaub lig seem; Cov lus no tseem hu ua "box". Feem ntau, cov kev siv yog siv los ua ib qho kev ua kom muaj kev ruaj ntseg thiab faib txoj kev sib thooj. Nws kuj zoo kawg thiab tostands cov teebmeem ntawm axial thiab dabtsi yog khoov loads.

Lawv tau ua dab tsi?

Raws li hais raug cov ntaub ntawv uas, feem ntau siv ntau hom steel (structural steel nrog alloying additives, tsis tshua muaj thiab siab carbon), nyob ntawm seb cov kev cai ntawm cov qauv. Li no, nyob rau hauv qhov tseeb, lub npe - "hlau channel". Muaj qee zaum, piv txwv li nyob rau hauv lub tsev tsheb, tshwj xeeb cov kev cai raug txwv rau hauv cov dej: lawv yuav tsum muaj cov khoom siv anticorrosive. Rau cov hom phiaj no, cov khoom tshwj xeeb tsis muaj txoj hlua tsis raug tsim, cov nqi uas yuav siab dua, tab sis nrog cov khoom ntim cov thermophysical uas lawv muaj ntau dua rau sab nraud influences, piv txwv li nrog cov npau taws kub.

Kev faib tawm

Cov hlau channel raws li ib yam khoom hlau yuav tsum yog tso tawm raws li hauv qab no:

1. Nyob ntawm seb txoj kev siv ua khoom siv:

• Channel steel kub dov (manufactured los ntawm kub dov);
• Tshwj xeeb;
• Bent equilateral (ua los ntawm txoj kev ntawm txias khoov rau khoom siv tshwj xeeb yob);
• Bent tsis sib npaug (manufactured siv tib lub tshuab qub li yav dhau los).

Los ntawm txoj kev, nws yuav tsum tau sau tseg tias txoj hlua kub kub kub yog txawv ntawm qhov khoov nyhiab: tom kawg yog ua tau thaum lub ntsej muag sib npaug, qhov ntawd yog, qhov khoom tsis muaj ntse ces, thaum cov kab kub kub yeej muaj cov ces kaum (saib duab hauv qab).

2. Nyob ntawm tus qauv thiab qhov loj:

• Y - hom no muaj sab hauv sab hauv ntawm txee nrog ib txoj kab nqes;
• P - khoom nrog cov ntsej muag rau sab hauv;
• E yog ib qho qauv siv nyiaj txiag nrog cov khoom siv txaj muag;
• L - qauv ntawm ib lub teeb ci nrog rau cov ntsej muag;
• C - khoom ntawm ib tug tshwj xeeb series.

3. Raws li cov cim ntsuas ntawm qhov tseeb ntawm cov rolled hlau, cov kev tuaj yeem muaj peev xwm:

• A - chav kawm (hoob kawm siab);
• B - chav kawm (qhov tseeb nce ntxiv);
• B - chav kawm (hoob kawm ntawm cov txwm niaj zaus).
