Ib hom ntawm cov hlau dov nrov yog xuas nrig ntaus, los yog lwm yam xuas nrig ntaus hlau. Qhov no yog cov khoom pov tseg tom qab nias ntau lawm. Thaum pib, qhov kev txiav tuag yog clad nrog tooj liab lossis tooj dag, yog li cov khoom tsim los ntawm nws ua haujlwm ntev.
Nov yog ib qho ntawm cov khoom siv los npaj ntau yam khoom. Piv txwv li, mus nqa tawm fencing ntawm ib tug private lub teb chaws tsev, lub caij ntuj sov nyob. Dab tsi yog qhov tseem ceeb, cov qauv yog mounted siv kev txiav tuag yooj yim heev thiab yooj yim, yog li koj tuaj yeem ua rau lawv tus kheej, tsis muaj kev pab sab nraud.
Khoom nta
Kev tsim khoom - kos duab los ntawm steel. Nyob rau hauv kub dov ntau lawm, nplooj ntawv yog tau nrog ib tug tuab ntawm 40-60 hli, nyob rau hauv txias-dov-dov - 15-20 hli, thiab thickness ntawm galvanized los xij - 7-8 hli. Cov theem tom ntej yog nias, uas ua rau kom tau txais cov nplooj ntawv ntawm lub dav hlau loj uas tuaj yeem tiv taus deformation. Kev siv cov txheej txheem ntau lawm thiab nws cov pov tseg xoom ua rau nws tuaj yeem tau txais cov khoom pheej yig dua.
Kev npaj rau kev siv, cov hlau perforation tsis xav taukev ua haujlwm, tab sis tom qab tsim kev tsim kho, piv txwv li, tib lub laj kab, nws tuaj yeem pleev xim kom cov hlau tsis pib oxidize los ntawm raug los nag lossis daus.
Txawm tias kev txiav tawm yog cov khoom pov tseg, cov qauv tsim los ntawm nws muaj zog thiab tuaj yeem tiv taus lub neej ntev.
txiaj ntsig
Hlau txiav, thiab tom qab ntawd cov khoom los ntawm nws, muaj ntau yam tseem ceeb. Cov no suav nrog:
- Nyob zoo ib tsoom phooj ywg.
- Tus nqi qis.
- Kev nyab xeeb.
- Ntau yam ntawm cov qauv perforation.
- Ib qho yooj yim installation.
- Tsim kev ntseeg tau.
Qhov zoo ntawm cov khoom muaj xws li qhov tseeb tias tsis muaj seams lossis tawg ntawm cov nplooj ntawv. Tsis tas li ntawd, cov khoom muaj pes tsawg leeg tsis suav nrog formaldehyde thiab lwm yam tshuaj tsis haum rau tib neeg. Xaus: hlau perforation yog ib qho ntawm lwm cov ntaub ntawv uas tuaj yeem tsim kev sib tw zoo rau cov khoom kim heev.
Uss
Ntau tus neeg siv khoom nyiam yuav cov khoom siv no vim nws muaj ntau yam, txij li kev txiav tuag tuaj yeem siv tau ntau yam:
- Raws li lwm txoj hauv kev sib txuas-txuas mesh.
- Tau tsim qhov cua ntxiv hauv qab laj kab.
- Nyob rau hauv paus.
- Rau kev txhim kho kev cib.
- Rau ua cov kauj ruam.
Qhov kev siv ntau yam yog vim qhov sib txawv ntawm cov khoom, raws li ob qho tib si ntawm cov ntawv tuab thiab ntawm cov khoom siv - nws tshwm simdaim ntawv (tsim rau laj kab) thiab yob (tsim rau kev txhawb nqa).
Parameters
Qhov ntev ntawm cov ntawv txheeb yog qhov tseem ceeb heev yog tias cov hlau perforation yog siv rau cov ntaiv. Hauv qhov no, nws yuav tsum ua raws li qee qhov ntsuas geometric ntawm cov ntsiab lus hauv qab no:
- Qhov sib txawv siab tshaj plaws hauv daim ntawv qhov ntev raws qhov ntev ± 25 hli, thiab raws qhov dav ± 10 hli.
- Torn qauv yuav tsum tsis txhob muaj qhov chaw ntawm nplooj ntawv.
- Yog tias thaj chaw uas tsis tuaj yeem tau npaj rau ntawm ib sab ntawm daim ntawv, nws qhov dav yuav tsum tau pom zoo nrog tus neeg siv khoom ua ntej.
Cov ntaiv nruab nrab ntawm lub davhlau, thaum lub sij hawm tsim kho uas siv cov hlau perforation, suav hais tias yog qhov yooj yim tshaj plaws thiab yog li ntawd tau tsim nyob txhua qhov chaw. Tsis tas li ntawd, lawv cov installation tso cai rau koj kom txuag tau qhov chaw hauv chav. Muab rau hauv tus account cov yam ntxwv nta, cov khoom ntaiv yog cov hauv qab no:
- Nrog cov hlua. Qhov no yog lub npe ntawm inclined beams nyob rau ntawm qhov chaw. Lawv yog lub hauv paus ntawm cov kabmob sab. Cov ntsiab lus kawg ntawm lub peb hlis ntuj hauv cov khoom no raug kaw nrog bowstrings.
- Nrog braids. Cov duab ntawm cov khoom yog sawtooth kom cov kauj ruam tuaj yeem tso rau ntawm lawv.
