Kev lag luam niaj hnub niaj hnub no muaj kev xaiv ntau ntawm cov khoom siv hauv tsev, ntawm cov ntoo laminated yog nrov tshwj xeeb. Nws yog qhov txawv ntawm qhov zoo heev, lub zog zoo, cov yam ntxwv zoo heev, kev yooj yim ntawm kev teeb tsa. Rau nws cov khoom siv, tsuas yog cov ntoo zoo (pine, spruce, cedar) yog siv, ua tsaug rau cov nqaj tau pom dav siv tsis yog hauv kev tsim kho xwb.
Cov qauv kev lag luam loj yog feem ntau ua los ntawm nws: warehouse complexes, water parks, skating rinks, ua luam dej pas dej ua ke, thiab lwm yam. rubles. Tab sis, txawm li cas los xij, tus naj npawb ntawm cov neeg tsim khoom uas nyiam nws tau nce ntau thiab ntau dua. Hauv peb tsab xov xwm, peb yuav xav txog cov yam ntxwv thiab qhov ntev ntawm cov kab teeb ci rau kev tsim lub tsev.
Kev siv ntoo
Laminated ntoo muab faib ua ob pawg loj:
- Cov khoom siv rau kev tsim cov phab ntsa. Nws tuaj yeem yog cov ntoo zoo tib yam thiab nws cov khoom siv insulated.
- Cov khoom tsim tsim rau ntau yam qauv. Qhov no suav nrog ncaj, khoov, qhov rais laminated ntoo, pem teb kab teeb, thiab lwm yam.
Key nta
Ntawm qhov zoo ntawm cov ntoo laminated, qhov ntev ntawm qhov peb yuav xav txog tom qab hauv tsab xov xwm, peb tuaj yeem sau tseg:
- Qhov muaj cov thermal rwb thaiv tsev siab thiab thermal conductivity tsawg, uas tso cai rau kev tsim vaj tsev tsis txhob siv cov txheej txheem thermal rwb thaiv tsev ntxiv, uas tuaj yeem txuag nyiaj ntau ntawm rwb thaiv tsev.
- Qhov no yog ib qho khoom siv hauv tsev, vim tsuas yog cov nplaum nplaum zoo siv rau nws cov khoom. Glulam muaj peev xwm tswj tau cov av noo nyob hauv tsev thiab muaj cov tshuaj tua kab mob zoo heev.
- Lub tsev ua los ntawm cov ntoo no muaj lub neej ua haujlwm ntev.
- Tus qauv khaws nws cov duab geometric tau ntau xyoo thiab xyaum tsis ntsws.
- Vim yog kev ua cov khoom tshwj xeeb, cov ntoo laminated nplaum yog tus cwj pwm los ntawm kev tiv thaiv hluav taws ntau ntxiv.
- Lub zog thiab seismic tsis kam ua rau nws siv tau cov ntoo no rau kev tsim vaj tsev yuav luag thoob plaws tebchaws Russia.
Sizeglued thiab profiled ntoo
Cov ntoo no yuav tsum ua raws li qhov yuav tsum tau ua ntawm GOST, SNiP thiab cov duab kos ua haujlwm, uas tau lees txais raws li kev sau tseg. Thaum tsim ib lub tsev, qhov luaj li cas ntawm cov kab hlau nplaum tsis muaj qhov tseem ceeb.
Raws li qhov ntev ntawm cov khoom nkag siab, ua ntej ntawm tag nrho cov, nws:
- siab;
- dav;
- length.
Hauv qhov no, ntu ntu ntawm cov khoom tuaj yeem yog:
- rectangular;
- square;
- ntau yam.
Yog tias nws yog cov khoom siv hauv tsev square, piv txwv li, qhov loj ntawm cov ntoo laminated yog 50x50, lawv feem ntau hais tias "thickness" vim tias cov kev ntsuas no zoo ib yam.
Standard Sizes
GOST 17580-92 muaj cov yam ntxwv tseem ceeb, cov ntaub ntawv tswj hwm thiab cov lus piav qhia ntawm cov kab teeb ci. GOST 20850-84 suav nrog cov kev cai ntxiv rau cov ntoo no.
Raws li cov kev cai teev tseg, cov tuam txhab muab qhov ntau thiab tsawg ntawm cov ntoo laminated (cov nqi yog qhia rau cov ntoo uas tsis yog profiled):
- dav - 8-38 cm;
- siab - 8-24 cm;
- length - los ntawm 1 txog 12 m.
Loj ntawm spruce thiab ntoo thuv:
- dav - 8-28 cm;
- length - 6-12 m;
- siab - 13.5-27 cm.
Nyob ntawm qhov pom ntawm cov qauv txhawb nqa, xaiv hom kab teeb: oval, duab plaub, thiab lwm yam.
Ntu ntu ntawm cov khoom siv no yog coj los nrog kev sib txuas, piv txwv li. Ntawd yog, kev suav yuav siv rau hauv tus account: assortment, machining, nyiaj pub dawb. Nws yog ib qho tsim nyog yuav tsum nco ntsoov tias lub thickness ntawm cov ntoo rau cov phab ntsa yuav tsum tau xaiv raws li qhov kev nyab xeeb ntawm lub cheeb tsam, yog li ntawd cov kev nplij siab thiab kev pom zoo rau kev nyob yog tsim nyob rau hauv lub chav tsev. Qhov tsawg kawg nkaus txoj kab uas hla ntawm cav rau sawing rau hauv ntoo yog 190 mm.
Beam loj raws li specifications
Txij li cov ntoo laminated yog tsim los ntawm gluing ib leeg cov laug cam (lamellas), nws qhov loj tuaj yeem sib txawv. Yog li ntawd, thaum xav txog ntau yam ntawm cov tuam txhab sib txawv, koj yuav ntsib nrog qhov tseeb tias ntau ntawm lawv muaj lawv tus kheej qhov loj ntawm cov khoom. Qhov no ua rau nws yooj yim xaiv cov thickness uas zoo tshaj plaws rau kev tsim kho. Ntxiv mus, nws muaj peev xwm los tsim cov kab teeb ci ntawm qhov ntau thiab tsawg.
Size Requirements
Cov kev cai nruj txaus yog raug rau ntawm cov kab teeb ci. Txij li thaum cov khoom no yog siv tsis tau tsuas yog rau kev tsim kho ntawm lub ntsiab load-bearing ntsiab ntawm lub tsev, tab sis kuj rau lub beam thiab rafter system ntawm cov plag tsev. Lub nqaj yuav tsum tiv taus qhov tseem ceeb ntsug loads zoo, tiv taus ntau yam kev cuam tshuam ib puag ncig (tsis rot, ignite, thiab lwm yam). Tsis tas li ntawd, nws yuav tsum ua kom ntev.
Rau lub hom phiaj no, ib qho kab teeb pom kev zoo yog qhov zoo heev, qhov hla ntawm qhov tsawg kawg yog 1/16 ntawm qhov dav dav. Qhov zoo tshaj qhov ntev ntawm cov ntoo laminated ntoo rau lub caij ntuj no lub tsev:
- ntu - 18x20 cm, 16x20 cm, 20x20 cm;
- kab ntev 6 thiab 12, 5 m.
Qhov no yog cov khoom siv zoo tshaj plaws rau kev tsim vaj tsev ntiag tug ntawm txhua qhov loj, txawm tias tus nqi siab. Koj tuaj yeem nyob hauv lawv, thiab tib lub sijhawm kho koj tus kheej, txij li cov ntoo ntuj hauv vaj tse tsim ib qho tshwj xeeb thiab noj qab nyob zoo microclimate.
Nyob rau lub caij ntuj no nws yeej ib txwm sov heev nyob rau hauv xws li ib tsev, thiab nyob rau hauv lub caij ntuj sov tshav kub nws txias. Tag nrho cov no txuag nyiaj ntawm cov cua sov, yog li siv cov khoom ntawd tau txais txiaj ntsig zoo.
Scope ntawm ntoo, raws li nws qhov loj me
Ntau tus tswv yuav tsum xaiv qhov tuab npaum li cas glulam yuav tsum yog. Lub thicker lub lumber, qhov zoo dua nws thermal kev ua tau zoo. Tab sis tib lub sijhawm, tus nqi ntawm cov khoom loj dua yog ntau dua.
Raws li tau sau tseg hauv cov lus qhia, qhov siab ntawm cov kab teeb xyaum tsis cuam tshuam rau lawv cov yam ntxwv. Tsuas yog tus naj npawb ntawm cov crowns hauv ib lub tsev ua los ntawm cov ntoo siab tsawg dua. Lub tsev zoo li no yuav zoo dua me ntsis, tab sis tus nqi ntawm lub tsev yuav siab dua me ntsis.
Qhov kev xav tau tseem ceeb rau qhov ntev ntawm cov ntsiab lus yog lawv txoj kev ncaj ncees, piv txwv li yuav tsum tsis muaj cov pob qij txha ntawm qhov chaw rau thawj lub kaus mom thiab phab ntsa trims ua ntej kev tsim kho ntawm interfloor thiab attic floors.
Scope ntawm ntoo raws li TU raws li nws qhov ntev:
- Wall: 14 × 16, 14 × 24, 14 × 20, 17 × 20, 14 × 28, 17 × 16, 17 × 24, 17 × 28 cm.
- Rau cov kab hauv pem teb: dav ntawm 95 txog 260 hli, qhov siab ntawm 85 txog 1120 hli,
- Glued laminated ntoo rau qhov rais loj: 80x80, 82 x 86 thiab 82 los ntawm115 mm.
hom ntoo rau kev tsim cov kab teeb
Glued laminated ntoo tuaj yeem ua los ntawm ib hom ntoo lossis ua ke los ntawm ob hom. Cov ntaub ntawv tseem ceeb rau kev tsim cov khoom siv hauv tsev no yog cov ntoo uas pheej yig heev - spruce thiab ntoo thuv.
Raws li kev txiav txim rau kev tsim cov kab teeb ci kuj tseem siv tau xws li cov ntoo coniferous thiab deciduous xws li:
- fir;
- cedar;
- oak;
- linden;
- larch;
- birch;
- alder.
Glulam nyhav
Hauv kev tsim cov kab sib xyaw ua ke, chamber ziab ntawm tag nrho cov khoom yog qhov tseem ceeb heev. Vim li no, lawv qhov hnyav yog tsawg dua li ntawm cov khoom siv ntoo. Qhov nruab nrab, qhov hnyav ntawm ib lub cubic meter ntawm cov ntoo laminated tuaj yeem muaj li ntawm 430 txog 480 kg. Thiab ib lub voos xwmfab ntawm edging khoom, uas muaj ntuj ya raws, yog hais txog 700 kg.
Hauv qhov no, yuav luag tib cov ntoo siv, uas muaj tib qhov ntom. Qhov sib txawv ntawm qhov hnyav tuaj yeem piav qhia los ntawm kev ua tib zoo ziab ntawm cov khoom siv raw no. Hauv qhov sib xyaw ua ke, qhov feem pua ntawm cov dej noo yog li 8%, thiab hauv cov khoom siv ntoo nws yog ze li ntawm 20%.
Profile ntoo
Cov neeg tsim khoom tsim tsis tsuas yog cov kab hluav taws xob du, tab sis kuj yog ib qho analogue uas muaj kev sib txuas ntev ntev. Hauv qhov no, cov duab ntawm qhov profile txawv.
Muaj ob lub ntsiab ntawm kev sib koom ua ke ntawm cov kab ntoo: Finnish thiab Swedish. Nws yog lawv uas tau los ualub hauv paus rau invention ntawm ib tug loj tus naj npawb ntawm intermediate conjugations: "ob", "comb", "triple", thiab lwm yam.
Zoo kawg
Yog li, peb tau txiav txim siab seb qhov loj npaum li cas ntawm cov kab teeb ci. Ob qho tib si ntoo me me 50x50 mm, tsim rau rooj tog, thiab nws cov phab ntsa loj dua, piv txwv li, 25x25 cm, yog qhov zoo sib xws. Glulam yog siv niaj hnub no rau ntau txoj haujlwm, los ntawm kev tsim tsev mus rau ua rooj tog.
