Hnub no, tej zaum, tsis muaj ib cheeb tsam ntawm kev tsim kho (txawm nws yog kev tsim kho vaj tse lossis kev lag luam ntawm ntau lub hom phiaj), qhov twg cov hlau profile yuav tsis siv. Nws yog siv rau kev faib phab ntsa, cov ceilings cuav, theem thiab phab ntsa cladding (ob qho tib si sab hauv tsev thiab sab nraum zoov).
Nrog ntau yam ntawm cov duab hla ntu, cov hlau profile yog qhov tseem ceeb ntawm cov hlau nyias nyias nrog lub zog zoo. Resistant rau kev hloov ntawm qhov kub thiab av noo, ruaj, tsis cuam tshuam los ntawm pwm thiab fungus, niaj hnub no nws yuav luag hloov ib zaug nrov siv ntoo beam.
Tshuaj hlau profile los ntawm txias dov. Txhawm rau kom muaj zog txhua yam, stiffeners raug tsim ntawm qhov profile. Raws li txoj cai, cov hlau ua tiav yog galvanized, uas ua rau lawv tsis kam mus corrosion. Aluminium kuj tseem siv rau kev tsim cov profiles,uas, txawm nws lightness, kuj muaj ib tug ncaj siab zog.
Rau kev tsim kho cov qauv yooj yim sib sau ua ke rau kev lag luam thiab kev lag luam, nrog rau kev tsim vaj tsev nyob thiab chaw ua kis las, siv cov hlau square profile, uas yog ua los ntawm calibrated square steel (nrog rau qhov dav profile. ntawm 6 mus rau 200 hli, tswj los ntawm GOST 2591-88). Nws yog siv nyob rau hauv cov ntaub ntawv tsim nyog, vim lub square, uas tsis muaj xws li rigidity raws li ib tug channel (los yog ib tug I-shaped hlau profile), siv tsis tau raws li ib tug ywj siab bearing element.
Hlau profiles siv rau kev tsim cov thav duab lossis rau sheathing yog conventionally muab faib ua plaub hom:
- Rackmount. Nws muaj U-puab nyob rau hauv nws hla ntu thiab muaj lub nraub qaum, nrog rau ob lub rhawv khoov ntawm lub kaum sab xis. Peb qhov grooves feem ntau khiav raws tag nrho qhov ntev ntawm cov txee, thiab muaj qhov qhib rau sab nraub qaum, uas yog siv los txuas cov rwb thaiv tsev lossis tso cov kab kab.
- Qhia. Nws kuj muaj U-puab, tab sis tsis muaj longitudinal grooves. Feem ntau siv los ua ib hom "rail" rau hauv qhov chaw khib nyiab nkag.
- Qab nthab. Nws txawv ntawm cov khib nyiab loj. Feem ntau lawv yog cov qauv - 60x27 hli nrog ntev ntawm 3 m. Raws li lub npe implies, lawv feem ntau yog siv nyob rau hauv kev tsim cov thav ntawv thiab ceilings (xws li ua ke thiab ntau theem sawv daws yuav).
- Qhia qab nthab profile. Ua haujlwm tib yam li daim ntawv qhia kev qhia,txawv ntawm nws qhov ntev - 28x27 mm (ntev 3 m).
Muab tso rau nws yooj yim, txhua lub khib lossis qab nthab hlau profile muaj nws tus kheej cov lus qhia, thiab kev xaiv ntawm hom xav tau tsuas yog nyob ntawm cov yam ntxwv ntawm cov qauv tsim thiab kwv yees thickness ntawm phab ntsa yav tom ntej lossis muab faib.
Ntxiv rau qhov saum toj no, tseem muaj kaum thiab arched profiles. Cov qub feem ntau yog siv rau theem kaum thiab tiv thaiv lawv los ntawm ntau yam kev puas tsuaj, thaum lub tom kawg yog siv los muab ntau yam duab rau ceilings lossis arched doorways. Rau fastening hlau hangers rau lub hauv paus bearing, ncaj hangers yog siv, nrog kev pab los ntawm cov yav tom ntej nto kuj dlhos horizontally los yog vertically.
