Thaum txhim kho lub laj kab, koj tuaj yeem tsis ua yam tsis muaj ncej, uas ua hauj lwm pabcuam rau tus qauv thiab paub tiv thaiv lub ntsej muag. Nws yog rau lawv tias cov khoom rau lub laj kab txuas nrog, seb nws yog corrugated board, brick , wood boards los yog slate. Tab sis yuav ua li cas xaiv cov ncej rau laj kab, yog tias cov khoom muaj nqis ntau ntau hom kev txhawb nqa cov txheej txheem? Hais txog qhov no hauv qab no.
Kev faib tawm ntawm laj kab sib txawv ntawm hom ntawm seem
Cov khoom no muaj ntau qhov kev cais tawm, tiam sis feem ntau yog nyob hauv seem ntu thiab cov khoom siv los tsim. Raws li hom ntawm seem, tag nrho cov kab yuav raug muab cais ua peb hom:
- Hloov cov ncej rau laj kab . Lawv siv thaum tsim nyog los txo cov nyiaj ua haujlwm hauv av, raws li lawv tuaj yeem raug raus hauv av los ntawm kev sib tsoo lossis tsav tsheb. Tsis tas li ntawd, lags tau yooj yim txuas rau lawv. Kev twb kev txuas yog los ntawm, yooj yim rau tshuab, nws yog ib qho yooj yim los tiv thaiv ntawm corrosion nrog xim. Lub welded seam muaj lub siab ceev zog (li 1.2 tons ntawm kev lag luam), uas yog ob peb zaug ntau tshaj qhov khoom uas tau ua los ntawm cua daj cua dub.
- Square ncej rau laj kab . Lawv muaj lub zog loj zuj zus, tab sis rau lub hom phiaj no qhov kev teeb tsa yuav tsum yog ncaj qha mus rau lub laj kab. Tab sis nws muaj ib qho teeb meem - qhov chaw ntawm lub lag luam mus rau cov yeeb nkab yuav yog qhov chaw ntawm corrosion, uas tsis tuaj yeem nres. Qhov no yog vim muaj qhov tseeb tias lub dav hlau tsis raug kaw hauv qhov chaw uas cov kav dej sib tshooj sib tshooj, uas ua dej tau tuaj yeem txuam nrog. Thiab qhov no yog qhov mob uas iron corrodes sai sai. Lub weld seam tsuas ua rau qhov teebmeem loj dua. Rau 3-4 xyoo lub pob txha txhuam yuav ua kom tag thiab lub laj kab yuav tsum kho lossis hloov. Ntxiv rau qhov piav qhia tsis zoo, nws tseem yuav tsum tau muab cov nqi ntawm cov khoom siv (square tube ntau tshaj qhov zoo sib xws thiab nws tus nqi yog kwv yees li 30% siab tshaj) thiab kev ua haujlwm ntawm qhov kev lag luam (nws yog qhov tsim nyog tias ib lub ntsej muag ntawm lub duab plaub yog nyob rau hauv dav dav hlau nrog lub laj kab).
- Ntsia cov duab rau laj kab . Pom yooj yim ntawm cov pawg, uas muaj ib qho taub thaum kawg nrog lub hau. Lawv muaj peev xwm muab ntsia tau rau hauv txhua qhov kev pab cuam, uas tsis muaj lub zog rau kev siv hluav taws xob. Nyob ntawm lub laj kab, koj tuaj yeem xaiv qhov kab ntawm lub qauv ntawm pawg. Yog li ntawd, rau ib daim phiaj lub pawg nyob rau hauv lub cheeb ntawm 55 mm yuav ze, rau ib tug profile profile - nyob rau hauv lub cheeb ntawm 76 mm.

Hom ntawm tshooj yog qhov tseem ceeb thaum ntsuas cov nqi ntawm lub laj kab thiab kev ceev ntawm kev txhim kho.
Lub lineup
Qhov nrov tshaj plaws yog cov hlau ncej rau laj kab. Lawv ua haujlwm ruaj khov heev, ua ke nrog txhua hom kev fencing thiab lawv tuaj yeem rov qab siv dua. Cov khoom ua los ntawm hlau yog feem ntau siv thaum nruab ib lub laj kab ntawm cov ntaub ntawv, cov hlau phom los yog cov pav ca. Ua ntej lub installation, cov ntawv yuav tsum tau pleev xim los tiv thaiv cov hlau txhuam hauv lub neej yav tom ntej.

Yog tias koj xav tau kev xaiv nyiaj, koj tuaj yeem siv ntoo ncej rau laj kab. Lawv tuaj yeem muaj ib lub xwmfab lossis vas-vev-kheej. Ua ntej installation, lub ncej yuav tsum tau ua tiav, tsob ntoo yog heev susceptible rau tus ntawm noo noo thiab cua. Ib feem uas yuav faus rau hauv cov av yuav tsum tau kho nrog bituminous impregnation, uas yuav ua rau ntoo resistant rau dej thiab acids. Sab saum toj ntawm cov pawg yuav muab pleev xim rau cov xim vov xim. Ua ntej ua ntej, tsis txhob hnov qab kom qhuav thiab txhuam cov pais.

Hniav tus ncej rau ib lub laj kab
Qee cov tswv yim hais txog lub laj kab raws li lub peev txheej, uas yuav ua rau kev tiv thaiv thiab kho kom zoo nkauj ntawm lub tsev ntau xyoo. Thiab ua kom nws muaj qhov tseem ceeb ntawm lub façade ntawm lub tsev, xws li cov khoom siv ua tiav cib, cov pob zeb qus thiab cov laj kab tshwj xeeb. Los txhim tsa ib lub pob cib los yog pob zeb rau lub laj kab, nws yog ib qho tsim nyog los ua ntej-pib lub hauv paus thiab mam li npaj cov masonry raws li cov txheej txheem npaj ua ntej. Txoj haujlwm yog qhov nyuaj heev, tab sis qhov kawg ntawm qhov tsim nyog yuav tau ua.
