Pem teb beams: Hom muab xam

Yuav ua li cas los tsim kom tau ib tug uas tsis muaj-sawv lub tsev thiab txuag on ntaub ntawv thiab cov nqi? Xaiv nyob rau hauv kev tsim kho beam ceilings. Lawv yog cov feem ntau pheej yig dua, thiab lawv tus me nyuam thiab installation tsis li mus rau ib tug loj loj zog. Pem teb beams ua ib tug ntau ntawm kev khiav dej num. Saum toj no tag nrho, lawv ua raws li ib tug diaphragm nruj nyob rau hauv kab rov tav seem tsev, li no kom ntseeg tau nws lub dag lub zog thiab stability.

Ntoo pem teb joists

Niaj hnub no lawv yog cov tsis tshua nrov nyob rau hauv cov pa tsev nyob thiab kev tsim thiab yog siv rau cov kev siv ntawm ntoo thiab ncej tsev. Ntawm no yog tsuas ib tug loj "tab sis": lawv ntev xwb, yog li interfloor deb tej zaum yuav tsis ntau tshaj 5 m, rau hoob nyob sab sauv - 6 m Feem ntau kab teeb ua los ntawm coniferous thiab deciduous ntoo .. pem teb qauv yog tsis muaj lwm yam tshaj li qhov ncaj beam koj tus kheej, lus, rwb thaiv tsev thiab flooring.

Hauv qab daus thiab hauv qab daus siv

Cov yooj yim yuav tsum tau rau xws overlap yog ib tug zoo lub dag lub zog. Txij li thaum nyob rau hauv cov ntaub ntawv no hauv lub beam yuav pab raws li tus puag pem teb, lawv yuav tsum yog li ntawd mas hnyav load.

Yog hais tias nyob rau hauv cov thawj pem teb muaj yog ib tug chav nres tsheb thiab ib tug lossis loj qab daus, nws yog zoo dua mus tsim ib hardwood pem teb yog tsis cov ntoo thiab hlau crossbars rau. Qhov no yog vim lub fact tias hauv pem teb kab teeb ntawm ntoo rot thiab yog tsis ib txwm tau mas hnyav loads. Nws yog tseem tau mus txo qhov kev ncua deb ntawm lub thaum uas tig mus tuav.

nthab pem teb

Lub hauv paus ntsiab lus tsim kho ntawm lub ntaus ntawv nthab pem teb yuav ua tau ywj siab los yog yuav ib tug continuation ntawm lub-ru tsev, i.e. yuav ib tug ru tsev system tivthaiv. Ntau kuab thawj embodiment, vim nws yog maintainable. Nyob rau hauv tas li ntawd, nws kom ib tug zoo dua lub suab rwb thaiv tsev. Ua li no, xaiv thiab stacked beams nyob rau hauv kev ua raws cai nrog rau tej kev yuav tsum tau. Ua ntej ntawm tag nrho cov, tag nrho cov kab teeb ntawm lub nthab qab nthab yuav tsum tsuas yog los ntawm cov qhuav ntoo, dua li softwood (ntoo thuv, spruce, larch).

Yog li ntawd hais tias lawv tsis tau ua lub qhov tsua nyob rau hauv, lawv muab tso sib nrug ntawm ib tug deb ntawm 1 Meter los yog los ze zog. Lub muaj zog dabtsi yog khoov beam yog pom tias yuav nthab pem teb, uas muaj ib tug nam piv ntawm seem 7: 5.

Lub txhawb pem teb

Tsim feature yog cov nyhuv ntawm "ob nyob rau hauv ib tug": nyob rau hauv ib tes, pem teb joists yog joists rau hauv pem teb, thiab nyob rau tib lub sij hawm, nyob rau lwm yam - ib tug them nyiaj yug rau lub qab nthab. Feem ntau, lub qhov chaw nruab nrab ntawm lawv yog lawm ua tus sau nrog ib tug tshwj xeeb thaum tshav kub kub thiab suab insulating cov ntaub ntawv uas, nrog rau cov kev tsis pom nrias siv vapor teeb meem. Cov pib nyob rau hauv qab lawm gypsum board, thiab rau sab saum toj drags floorboard.

Kab teeb ntawm ntoo plag tsev tuaj nyob rau hauv ob peb hom, txhua tus uas muaj nws tus kheej zoo.

Khoom ntoo beam

Rau lawv lawm tsuas yog siv khoom ntoo hardwood. Rau hnub tim, hauv pem teb decks rau xws sis tsis ncaj tuav no yog ua los siv khoom ntoo heev dua lwm yam ntawm me me tau saib ntsoov txog ntev (txog li 5 meters).

Laminated ntoo kab teeb

Cov ntoo joists tsis txwv qhov ntev li yog muab los ntawm lub ntau lawm tshuab pub rau txim tuag rau lawv txaus ntev.

Vim lub nce lub zog ntawm lub laminated beams yog siv nyob rau hauv tus neeg mob qhov twg nws yog tsim nyog los mas ib tug hnyav load rau hauv lub sib tshooj.

Pros glued beams:

• zoo zog;
• yuav ntawm loj overlap spans;
• yooj yim ntawm installation;
• tsis muaj qhov hnyav;
• ntev kev pab cuam lub neej;
• muaj tsis muaj deformation;
• zoo hluav taws kev ruaj ntseg.

Maximum ntev yog muab los ntawm lub cav ntoo 20 meters.

Txij li thaum xws joists muaj ib tug du nto, lawv feem ntau tsis xaws lub hauv qab, thiab lawv thiaj li qhib, tso rau hauv lub chav heev fashionable tsim sab hauv.

Tus ntoo khaub lig seem ntawm cov ntoo kab teeb

Raws li pom tias, tus ntoo khaub lig-seem ntawm cov kab teeb muaj ib tug ncaj yam teeb meem loj rau cov muaj peev xwm withstand load. Thiaj li, qhov yuav tsum tau los siv rau pre-xam-seem ntawm cov khoom no.

Pem teb beams tsev yuav muaj ib tug rectangular, square los yog yeej tus ntoo khaub lig seem.

Raws li interfloor beams nyob rau hauv cov tsev ntoo nyob rau hauv thiaj li yuav tsim lub beam tej zaum yuav siv tau.

Peb cia siab tias ib tug hardwood pem teb

Qhov kev ncua deb ntawm cov ntoo kab teeb yog txiav txim los ntawm:

• Firstly, cov yuav loads.

Lub load yuav feem ntau yuav qhov: qhov loj ntawm overlapping hnyav partitions ntawm chav los yog yuag truss system. Thiab ntxiv rau cov - nce mus nce los: nws yog sib npaug zos rau 150 kg / m. (Raws li SNP 2.01.07-85 "Loads thiab cov nyhuv"). Lub thiaj li hu ua nce mus nce los loads muaj xws li tus luj ntawm lub rooj tog, tag nrho cov khoom, cia li tej yam uas muaj nyob rau hauv tib neeg lub tsev.

Yog li ntawd yuav ua li cas nyiaj rau tag nrho cov tau loads nyuaj heev, nws yog tsim nyog los npaj sib tshooj nrog cov paj tau paj ntawm lub fortress. Cov tub txawg qhia ntxiv 30-40 feem pua.

• Secondly, qhov dabtsi yog khoov rigidity los yog cov txheej txheem nqi.

Rau tej hom ntawm cov ntaub ntawv uas yog txiav txim los ntawm GOST tus kheej txwv nruj. Cuaj kaum, cov mis rau tus muab xam yog tib yam: cov kev sib piv ntawm lub meej npaum li cas ntawm deflection ntawm ib tug nqaj kom muaj nuj nqis.

Muab xam los ntawm hauv pem teb beams

Tus txheej txheem ntawm kev xam lub qab nthab ntoo beams es laborious. Dhau li ntawm tus fact uas koj xav tau kom zoo zoo xaiv qhov kev ncua deb ntawm lawv, thiab yuav tsum tau txiav txim seb tus ntoo khaub lig seem nws tus kheej kom raug. Rau lub hom phiaj no, pre-xam tus nqi ntawm cov deflection ntawm ib tug muab load rau ib tug muab tus ntoo khaub lig-section. Yog hais tias no tus nqi ntau tshaj cov cai txwv, lub qab nthab beams coj los ntawm ib tug loj ntoo khaub lig seem.

Raws li ib tug txoj cai, muab xam rau ntawm ntoo kab teeb los ntawm cov nram qab no mis. Txawm li cas los, koj yuav tau siv thiab qhia tshwj xeeb uas tsim tswvyim rau xam xyuas cov tshooj ntawm cov ntaub ntawv muab. Nws tso cai rau koj coj mus rau hauv tus account tag nrho cov kev sib nrauj, tsis looj koov mus nrhiav cov ntaub ntawv thiab los ntawm xam.

Yog hais tias tus kab teeb muab tso ua ke, lawv yuav hloov lub load ob zaug kom ntau li ntau, thiab nyob rau hauv rooj plaub yog tias koj muab tso rau hauv sab saum toj ntawm txhua lwm yam - sawv qhov load yog hais txog plaub lub sij hawm loj.

Hlau joists

Qhov thib ob nrov tshaj plaws hauv daim ntawv ntawm qab nthab beams - nws yog hlau. Lawv zoo: lawv yog cov check, txhim khu kev qha, muaj ib tug me me thickness, thiab yog li ntawd economize qhov chaw. Cov cab kuj tivthaiv muab cov ntaub ntawv uas - dov profile. Muaj 3 hom: ces kaum, raws thiab I-kab teeb. Nyob rau hauv ib tug tub lim nruab nrab ntawm lawv siv lub teeb ua vaj tse inserts los yog thiaj li hu ua khaub-ncaws nyias RC-phaj ntxiv txhua yam - ntoo panels. Lub ntsiab kom zoo dua yog qhov hlau beams uas saib ntsoov txog cov dav ntawm 4-6 meters los yog ntau txawm tias. Lawv disadvantage yog hais tias lub hlau joists heev resistant rau corrosion thiab muaj ib tug txo thermal thiab acoustic rwb thaiv tsev, txawm li cas los, qhov no yuav pab tau ib tug raug felt.

Muab xam los ntawm cov hlau joists

Nws yog tsim nyog yuav tau nco ntsoov hais tias lub xam (formula) yog tib yam rau tag nrho cov hom ntawm kab teeb. Qhov luaj li cas ntawm cov tau kuj taw tes, feem ntau yog cov tshev mis rau ib tug tshwj xeeb directory los yog xam ntawm ib tug tshwj xeeb tshuab xam zauv, pem teb beams, nws muaj peev xwm yuav nrhiav tau nyob rau hauv lub ntiaj teb no network uas tsis muaj teeb meem.

Pem teb beams: nqi

hais tias yog heev yooj yim mus tsis ncaj ncees lawm nrog hais tias qhov no hom ntawm beams nws yuav raug nqi ntau npaum li ntawd. Koj yuav tsum to taub hais tias tus nqi yog tsis tsuas nyob rau hauv cov nqe lus ntawm cov ntaub ntawv uas (eg, ntoo los sis hlau yog). Nws tsim yog los ntawm lawv cov nqi raws li zoo raws li lub chaw tsim tshuaj paus. Qhov tsawg kawg nkaus tus nqi ntawm ib tug ntoo beam yog 219 rubles. ntawm m / n.
