H-puab profile yog lub hauv paus tseem ceeb ntawm lub qhov rais, qhov rooj, tshuaj xyuas qhov faib ua los ntawm cov hlau thiab yas. Nrog tus qauv H-puab, nws yooj yim los teeb tsa lub qhov rai saib, lub qhov rooj zawv zawg lossis zawv zawg thiab ntau yam qauv zoo sib xws.
Peculiarities
Qhov sib txawv tseem ceeb yog ntu ntu ntawm cov hlau profile hauv daim ntawv H. Sab ntsug ntawm "tsab ntawv" no yuav txawv lossis zoo ib yam. Cov phab ntsa tuab ntawm cov ntaub ntawv zoo li no (ntev thiab hla), cov khoom muaj zog dua. Qhov ntau dua los ntawm iav, vaj huam sib luag yas, sib xyaw ua ke lossis txawm tias lub rooj tsavxwm, nws yuav tiv taus.
H -qauv - hauv nws qhov tsis muaj - tuaj yeem sib sau ua ke:
- los ntawm ob ntu U-puab, sib npaug hauv qhov dav mus rau sab saud;
- ntawm ob lub C-puab, nrog nkhaus flanges raws ntug ntawm ob sab ntsej muag;
- ntawm ob qho tib leeg T-daim (T-puab daim).
Hauv qhov xwm txheej tom kawg, vuam yog qhov tseem ceeb. Yog tias U-thiab C-puab cov duab tuaj yeem txuas nrog bolts fasteners (yam tsawg kawg ntawm qhov kawg), tom qab ntawd vuam ntawm T-ntu tau ua los ntawm tus kws tshaj lij kev paub nrog kev paub hauv kev tso "rov qab" (kab rov tav, "hauv pem teb")) seams tau . Vuam ntawm T-profiles tau ua tiav raws li "crescent" txoj kev, zigzag lossis ncig (tig) txav ntawm qhov chaw ntawm kev sib cuag ntawm cov hluav taws xob nrog cov nplaim kom koom nrog. Qhov sib txuas ua ke "I-beam" yuav tsum muaj cov kab sib npaug thiab cov npoo sib luag. Nws tsis khoov, khaws nws cov duab thiab cov qauv hauv cov khoom tsim nyog, tau ntau xyoo.
Kuj tseem muaj H-ntu nrog ib puag ncig, sab hauv sab nkhaus ntsug . Cov tuab ntawm cov phab ntsa no tuaj yeem sib txawv - tuab mus rau ntawm ntug thiab ua kom ze dua mus rau ntug kev hla, lossis hloov pauv. Qhov no muab cov qauv ua kom zoo, txhim kho nws qhov tsos, ua rau cov qauv lossis cov rooj tog zaum, sab hauv nthuav tawm ntau dua.
Qhov ntev (kho kom raug)
Cov hlau profile tau ua nrog cov phab ntsa txog li 2-3 hli tuab, txhuas-2-3 zaug tuab dua vim qhov txo qis ntawm qhov hnyav ntawm txhuas. Lub thickness ntawm cov phab ntsa profile yog los ntawm ib mus rau ob peb millimeters.
Qhov loj ntawm qhov sib txawv ntawm H-profile profile hloov pauv nyob ntawm qhov haujlwm uas tau muab rau cov khoom . Yog li, lub koom haum ntawm "ntau-storey" txee lossis khib nrog lub kaw kaw kaw, faib rau qib sib txawv, yuav xav tau iav zawv zawg. Qhov qis, sab thiab sab saud tau muab coj los ua W-lossis U-puab cov qauv, thiab cov "cuam tshuam" yog H-puab, muab tso rau ntawm ib sab thiab ntsug.
Qhov xwm txheej ntawm no yog qhov no: qab nthab kab rov tav yuav tsum tsis txhob tawm mus - lawv tau so hauv qhov chaw uas tau txiav txim siab los ntawm cov phab ntsa ntawm lub txee lossis rooj saum txaj thiab tsom iav. Lawv sib luag rau ib leeg thiab rau phab ntsa kab rov tav ntawm cov khoom no.
Ib qho H-puab profile tau tsim nrog qhov sib txawv dav los ntawm chav nyob mus rau kaum ntawm millimeters . Cov txiaj ntsig raug yog 6-, 8-, 10-, 12-, 14-, thiab 16mm qhov khoob. Qhov ntev ntawm cov ntaub ntawv muag nyob rau hauv ntu sib txawv ntawm ib mus rau ob peb metres. 6mm feem ntau siv los ua chaw thau khoom - hauv cov chaw uas cov ntu yuav tsum tsis txhob sib dhos yooj yim.
Nws siv qhov twg?
H-qauv yog qhov tseem ceeb tshaj plaws. Nws tuav ib daim ntawv ntawm lwm yam khoom siv (iav, board lossis plywood, chipboard element, sheet of steel or composite layers in the form of a square / rectangle). Ua ntej tshaj plaws, H-profile yog cov khoom siv sib txuas. Ib qho piv txwv yog ib hom armstrong raug tshem tawm qab nthab hauv chav ua noj lossis chav noj mov ntawm ib lub tsev haujlwm tshwj xeeb, nrog cov hlau lossis txhuas lub xwmfab.
H-profile yog lub hauv paus tseem ceeb ntawm kev thaiv cov tsev (piv txwv li, nws yog ib feem ntawm cov soffits), lub ru tsev (yog tias tsis muaj kev nkag mus rau lub ru tsev profile). I -beam kev txhawb nqa tus qauv muaj ntau yam - nws tuaj yeem ntsia tau tav toj lossis ntsug.
Hlau I -nqaj - nyias phab ntsa thiab nrog cov phab ntsa qis dua qhov nruab nrab tuab - lub hauv paus rau plasterboard thiab ntoo ntu . Lawv tso cai rau tus tswv ntawm qhov chaw nyob rov npaj dua lub tsev lossis chav tsev - piv txwv li, faib ib chav loj hauv ob.
Cov tuab -phab ntsa I -nqaj - nrog cov tuab tuab tuab ntawm 10 millimeters lossis ntau dua - yog tus pabcuam hauv kev teeb tsa lub qhov rooj tshiab thiab qhib qhov rai . Nws yuav yooj yim nqa ntawm ntau tuj thauj khoom ntawm cov cib thiab ntu ntawm cov plag tsev cuam tshuam, tuav ib feem ntawm phab ntsa nyob saum toj no, siab dua qhov qhib nws tus kheej. Cov khoom lag luam zoo li no tsis siv hauv ib qho, tab sis hauv ob lossis ntau lub ntsiab lus - tsab ntawv H hauv qhov kev txiav raug muab tso rau "dag", ob npaug (triple, thiab ntxiv rau) H -profile tau tsim, uas muaj qhov chaw kaw hauv.
Cov lag luam uas siv H-bar lossis H-beam yog raws li hauv qab no:
- kev tsim nkoj, kev tsim dav hlau, kev tsim kho tshuab;
- kev tsim kho tsheb ciav hlau;
- kev teeb tsa thiab kev ua haujlwm ntawm lub qhov cua nkag;
- kho kom zoo nkauj ntawm tsev, vaj tse los ntawm sab hauv thiab sab nraum;
- tsim khoom lag luam, rooj tog hauv tsev thiab chaw ua haujlwm;
- kev tshaj tawm thoob ntiaj teb (cov ntawv tshaj tawm, cov pendants nrog saib, thiab lwm yam).
Kev lag luam ntau yam tshaj plaws yog kev tsim kho. H-profile tuaj yeem tso yuav luag txhua qhov chaw-thaum tsis muaj kev nkag tau mus rau L-, S-, P-, S-, F-puab cov ntsiab lus, thiab muaj ntau H-profile, txoj phiaj xwm hem kom ua tsis tiav. H -bar tau siv hloov pauv ntawm qee qhov lwm yam - yam tsis muaj kev siv nyiaj ntau dhau ntawm cov peev txheej.
Yuav xaiv li cas?
Tsom ntsoov rau lub nra uas tsim los ntawm qhov tshwj xeeb ntawm H-puab bar. Cov txheej txheem txhawb nqa ntawm cov tsev, cov tsev thiab cov txheej txheem xav tau yam tsawg ob peb millimeters ntawm cov hlau khov kho. Kev suav raws SNiP thiab GOST qhia tias nrog rau phab ntsa tuab qhov hnyav ntawm lub nra nce ntxiv tsis yog ib leeg, rau qhov no nws txaus los tshuaj xyuas cov ntaub ntawv hauv cov lus ntawm qhov muaj txiaj ntsig ntawm kev tso cai ntawm cov tuab sib txawv . Yog tias 5 hli hlau tuaj yeem tiv taus, piv txwv li, 350 kg, qhov no tsis txhais tau tias 10 hli hlau tuaj yeem tuav tau 700 qhov tseeb: tus nqi yuav nyob hauv thaj tsam ntawm ib tuj.
Tsis txhob hla qhov tuab ntawm phab ntsa thiab ntau yam khoom siv los ntawm qhov uas lawv tau ua: cov peev txheej yuav ua rau tawg thiab tawg thaum lub sijhawm - txog rau qhov ua kom tiav ntawm koj lub taub hau (thiab koj cov neeg nyob ze).
Rau kev tsim cov rooj tog, feem ntau yog cov phab ntsa nyias (1-3 hli) hlau thiab 1-6 hli txhuas. Ib qho tuab dhau H-bar yuav khoov hauv qab tus neeg (lossis ntau tus neeg) ntawm qhov ntom lossis tag nrho kev tsim, yog li ntawd, cov tuab ntawm cov hlau raug coj nrog cov npoo me.
Cov iav hauv lub qhov rais tsis zoo li yuav tsim lub nra rau ntawm lub qhov rais sill uas hnyav ntau dua li kaum tawm kilograms . Cov qhov rooj thiab qhov rooj (tshwj tsis yog kev txhawb nqa cov kabmob nyob rau sab saud ntawm qhov qhib) tsis xav tau siab dua qhov nruab nrab hlau lossis hlau tuab.
Kab hlau rhuav thiab kab hlau rhuav - txawm tias qhov hnyav tshaj hnyav tshaj 10 kg thaum quav - yuav tsis pom qhov cuam tshuam ntawm txhuas lossis hlau eaves . Qhov tseeb yog daim ntaub thaiv, ua ke nrog C-puab profile thiab pendants, teeb tsa ntawm H- lossis P-qauv, yog qhov hnyav sib npaug. Txawm hais tias koj txav tag nrho daim ntaub thaiv mus rau ib sab, tsuas yog L- lossis U-zoo li cov dai khaub ncaws lossis tus tuav tuav tag nrho cov no ntawm phab ntsa hauv txoj haujlwm kab rov tav yuav tsum tau thauj khoom. Phab ntsa tuab ntawm H-profile tsis tseem ceeb ntawm no- ob qho tib si 1- thiab 3-mm pob kws tuaj yeem siv tau. Qhov khoob yuav tsum dav txaus kom ruaj ntseg tuav cov khoom dai thiab kab hlau rhuav.
