Cov qhov rais niaj hnub yog qhov txawv ntawm ntau yam khoom, cov duab thiab xim. Lub ntiaj teb cov tuam txhab ua lag luam muab cov thav ntawv ua los ntawm txhuas, yas thiab ntuj ntoo. Thiab tsis muaj teeb meem dab tsi ntawm cov khoom siv hauv kev tsim cov qhov rais, ua tsaug rau cov cuab yeej tshiab thiab cov cuab yeej, txhua yam khoom sib npaug sib npaug thiab ruaj khov. Txawm li cas los xij, ib qho tsis zoo yuav tsum tau sau tseg ntawm no - tus nqi ntawm cov thav ntawv no yog qhov siab heev.
Tab sis tsis yog txhua tus tuaj yeem them taus yuav cov qauv tsim nqi $ 100-300 txhua qhov tsuas yog txhawm rau ci lub tsev cog khoom me me lossis veranda hauv lub tebchaws. Yog li ntawd, cov tswv feem ntau muaj cov lus nug: "Yuav ua li cas yog qhov rais thav duab ua nrog lawv tus kheej tes?" Peb yuav sim teb nws hnub no.
Npaj cov cuab yeej tsim nyog
Raws li kev xyaum qhia, qhov kev daws teeb meem yooj yim tshaj plaws thiab pheej yig tshaj yog tsim lub qhov rais ntoo. Ntoo yog yooj yim heev los tuavcov cuab yeej siv ntoo, yog li txawm tias tus tswv tshiab tuaj yeem ua haujlwm li no. Yog li, peb xav tau cov ntaub ntawv dab tsi rau qhov no? Ua ntej koj yuav tsum nrhiav cov ntoo qhuav los yog nplaum (cov plywood ib txwm ua). Ob peb ntawm nws cov nplooj ntawv yuav txaus los ua kom tiav cov haujlwm ntawm kev tsim lub qhov rais thav duab. Los ntawm cov cuab yeej, npaj ib tug saw, nrog rau rauj thiab ib tug chisel. Cov cuab yeej xws li hluav taws xob planer thiab milling cutters yuav pab tau zoo heev thiab ceev cov txheej txheem ntawm kev tsim lub qhov rais thav duab. Txawm li cas los xij, thaum tsis muaj cov cuab yeej siv no, ua-nws-koj tus kheej qhov rais thav ntawv tseem tuaj yeem ua tau - nws tsuas yog siv sijhawm ntau thiab siv zog siv rau kev ua haujlwm.
Tsis tas li ntawd, koj yuav xav tau iav, hlau fab, ntoo kua nplaum, thiab, tau kawg, kos duab ntawm cov khoom yav tom ntej. Yog tias koj xaiv cov laug cam ua cov khoom tseem ceeb, nws yog qhov zoo tshaj los xaiv cov khoom siv nrog ib ntu ntawm 50x150 millimeters.
Yuav ua li cas ua ib lub qhov rais nrog koj tus kheej txhais tes?
Ntawm no peb yuav saib yuav ua li cas lub qhov rais thav duab yog ua los ntawm cov ntoo laminated. Cov khoom no yog tus cwj pwm los ntawm kev ntseeg siab, lub zog thiab qhov hnyav hnyav. Rau lub qhov rais thav duab, glued laminated ntoo yog raws nraim qhov koj xav tau. Koj tuaj yeem siv lub bar tsis tu ncua, tab sis nws tsis zoo li cov khoom lag luam no yuav tiv taus ntau tshaj ib lub caij ua haujlwm.
Tau npaj tag nrho cov cuab yeej tsim nyog thiab kos duab, koj tuaj yeem ua haujlwm nyab xeeb. Ua ntej, peb ua ib lub qhov rais thav duab. Ua li no, ib tug zawj yog txiav tawm nyob rau hauv ib tug board nrog ib tug seem ntawm 50x150 millimeters thiaj li hais tias nyob rau hauv profilelub ntsiab yog zoo ib yam li tsab ntawv "G". Ua tsaug rau qhov kev txiav txim no, lub qhov rais yuav tiv thaiv ntau dua los ntawm ya raws thiab airtight.
Tom ntej no, koj yuav tsum suav (raws li daim duab) qhov ntev ntawm cov laug cam, thiab tom qab ntawd mus txiav lawv. Koj yuav tsum faib lawv ua 4 ntu, txhua qhov yuav txuas ua ke.
Txog txoj kev sib txuas
Thaum ua haujlwm, xyuam xim tshwj xeeb rau txoj kev sib txuas. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov boards tsis zoo yuav tsis lav qhov ua tau zoo ntawm lub qhov rais thav duab, uas txhais tau hais tias txhua qhov kev ua haujlwm hnyav yuav poob mus rau hauv qhov dej. Qhov tseeb thiab txhim khu kev qha kev sib txuas kev xaiv yog spikes thiab grooves. Koj tuaj yeem ua rau lawv ntawm lub tshuab milling phau ntawv. Yog tias qhov no tsis nyob ntawm tes, koj tuaj yeem siv txoj kev qub - txiav tawm tag nrho cov ntsiab lus nrog lub saw thiab lub chisel.
Thov nco ntsoov tias cov grooves tsuas yog ua rau ntawm qhov ntsug. Nyob rau ntawm cov laug cam uas yuav muab tso rau hauv kab rov tav, ib tug spike raug txiav tawm. Tom qab ob lub ntsiab lus tau tsim, cov pob qij txha tau ua tib zoo ua tiav nrog cov nplaum ntoo. Lub thawv yuav tsum tau txuas nrog kev saib xyuas zoo tshaj plaws, saib xyuas lub kaum sab xis ntawm 90 degrees. Tom qab ntawd, cov ces kaum hlau yog ntsia rau hauv cov ces kaum ntawm qhov kawg. Lawv tuaj yeem yuav ntawm txhua lub khw muag khoom kho vajtse. Lawv lub luag haujlwm tseem ceeb yog txhawm rau txhim kho lub qhov rais thav duab thiab tag nrho cov boards.
Ua ntej txhim kho cov fab hlau, tos ib pliag kom txog thaum cov nplaum nplaum qhuav tag. Tib lub sijhawm, koj tuaj yeem pib ua ntooncej.
Beam dimensions
Nws yog ib qho tsim nyog sau cia tias lub nqaj rau lub caij no yuav tsum muaj qhov me me - tsis yog 50x150 mm, koj yuav tsum tau siv 50x50 mm. Thawj kauj ruam yog los tsim ib qhov profile. Thaum ua txoj haujlwm no, tsis txhob hnov qab tawm qhov sib txawv me me (1-2 millimeters) ntawm tus ncej thiab lub thawv. Tom qab ntawd, qhov profile yuav tsum tau saws rau hauv qhov khoob, nyob rau hauv uas spikes yog ces txiav thiab grooves yog txiav. Cov ncej ncej txuas nrog tib yam li lub qhov rais ncej.
kawg theem
Nyob rau theem kawg, cov khoom no mus dhau ntawm cov txheej txheem glazing. Lub qhov rais thav duab thiab thav duab yog muab nrog hinges, thiab tom qab ntawd ob lub ntsiab lus raug kho nrog tus neeg saib xyuas tshwj xeeb kom ya raws kom muaj zog tiv thaiv.
Nov yog nws, peb lub qhov rais yuav luag npaj - nws tseem tsuas yog pleev xim thiab pleev xim rau saum npoo.
Kev tsim cov plywood qhov rais thav duab
Txij li lub Hoobkas tshuab rau kev tsim cov qhov rais thav duab yuav tsum tau tshwj xeeb cov cuab yeej kim thiab khoom siv, ua cov khoom siv hauv tsev yuav muaj teeb meem heev. Tias yog vim li cas craftsmen tau tsim lawv tus kheej txoj kev los tsim ib tug profile los ntawm fastening plywood strips. Rau xws li ib lub qhov rais thav duab, 4 strips yog txaus - lawv yog ces fastened nrog ib tug duab plaub. Tag nrho cov tshuab tsim muaj nyob rau hauv kev ua ob peb lub duab plaub los ntawm plywood strips ntawm txawv widths thiab kho lawv ua ke. Txoj kev no koj yuav tau txais cov ntoo puff zoo meej ntawm qhov xav tau teeb tsa.
Nrog kev pab los ntawm cov cuab yeej no, tsis yog tsuas yog ib lub qhov rais qhov muag tsis pom zoo nkaus xwb, tab sis kuj muaj lub qhov rais nrog ob thiab peb lub iav. Ib lub qhov rais ib qho yooj yim ua los ntawm 8 plywood strips. Lawv thiaj li tsim ob lub duab plaub (thaum lawv qhov dav me ntsis txawv ntawm ib leeg). Cov strips ntawm ob txheej yog txiav me ntsis nqaim - qhov no yog qhov tsim nyog txhawm rau txhim kho cov iav. Tsis tas li ntawd, ntoo qhov rais thav duab (xws li, tag nrho lawv qhov chaw) txuas nrog siv tus kheej tapping screws. Tag nrho cov ntsiab lus kho yog ua tiav nrog rau cov ntoo ua kua nplaum. Txhua yam, qhov rais thav duab ua los ntawm ntoo ntawm theem no tau ua tiav!
