Polycarbonate yog cov khoom siv polymer niaj hnub uas yuav luag zoo ib yam li iav, tab sis 2-6 zaug sib zog thiab 100-250 npaug zog dua .… Nws tso cai rau koj los tsim cov qauv tsim uas ua ke kev zoo nkauj, ua haujlwm tau zoo thiab ntseeg tau.

Cov no yog cov ru tsev pob tshab, lub tsev cog khoom, lub qhov rais qhib lub khw, lub tsev ci ci thiab ntau ntxiv. Rau kev tsim kho ntawm ib tus qauv, nws yog ib qho tseem ceeb uas yuav tsum suav kom raug. Thiab rau qhov no koj yuav tsum paub tias tus txheej txheem txheem ntawm polycarbonate panels yog dab tsi.

Qhov ntev ntawm daim ntawv honeycomb

Cellular (lwm lub npe - yam ntxwv, channel) polycarbonate yog cov vaj huam sib luag ua los ntawm ob peb txheej txheej yas, txuas sab hauv los ntawm txoj kab txuas ntsug (stiffeners) . Stiffeners thiab kab rov tav tsim cov hollow cells. Xws li cov qauv hauv ntu ib sab zoo ib yam li zib ntab, uas yog vim li cas cov khoom tau txais nws lub npe. Nws yog qhov tshwj xeeb ntawm cov xov tooj ntawm tes uas tso cai rau lub vaj huam sib luag nrog suab nrov ntxiv thiab tiv thaiv tshav kub. Nws feem ntau yog tsim nyob rau hauv daim ntawv ntawm cov ntawv ib lub duab plaub, qhov ntev ntawm uas tau tswj hwm los ntawm GOST R 56712-2015. Qhov ntev ntawm cov ntawv raug yog raws li hauv qab no:

• dav - 2.1 m;
• ntev - 6 m lossis 12 m;
• kev xaiv tuab - 4, 6, 8, 10, 16, 20, 25 thiab 32 mm.

Qhov sib txawv ntawm qhov ntev ntawm cov khoom siv los ntawm cov tshaj tawm los ntawm cov chaw tsim khoom hauv qhov ntev thiab dav tau tso cai tsis pub ntau tshaj 2-3 hli rau 1 meter. Hais txog qhov tuab, qhov sib txawv ntau tshaj yuav tsum tsis pub ntau tshaj 0.5 hli.

Los ntawm qhov pom ntawm kev xaiv cov khoom siv, cov yam ntxwv tseem ceeb tshaj plaws yog nws cov tuab. Nws muaj feem cuam tshuam nrog ob peb yam.

• Tus nab npawb txheej yas (feem ntau yog 2 txog 6) . Qhov ntau ntawm lawv, cov tuab thiab muaj zog cov khoom, zoo dua nws lub suab-nqus thiab cua sov-insulating zog. Yog li, lub suab rwb thaiv tsev ntsuas ntawm 2-txheej khoom yog kwv yees li 16 dB, coefficient ntawm kev tiv thaiv kom sov hloov pauv yog 0, 24, thiab rau 6-txheej cov khoom siv cov duab no yog 22 dB thiab 0, 68, feem.
• Qhov chaw ntawm stiffeners thiab cov duab ntawm cov cell . Ob lub zog ntawm cov khoom siv thiab qib ntawm nws qhov kev hloov pauv nyob ntawm qhov no (cov ntawv tuab dua, nws muaj zog dua, tab sis nws tsis zoo dua) Cov xov tooj tuaj yeem yog cov duab plaub, cruciform, daim duab peb sab, hexagonal, honeycomb, nthwv dej.
• Stiffener tuab . Kev tiv thaiv cov neeg kho tshuab kev nyuab siab nyob ntawm tus yam ntxwv no.

Raws li qhov sib piv ntawm cov ntsuas no, ntau yam sib txawv ntawm cellular polycarbonate tau txawv. Txhua ntawm lawv yog qhov zoo tshaj plaws rau nws cov haujlwm thiab muaj nws tus kheej cov qauv txheej txheem tuab. Qhov nrov tshaj plaws yog ob peb hom.

• 2H (P2S) - nplooj ntawv ntawm 2 txheej yas, txuas los ntawm cov kab txuas sib txuas (stiffeners), tsim cov duab plaub. Cov dhia dhia nyob txhua txhua 6-10.5 mm thiab muaj ntu hla ntawm 0.26 txog 0.4 mm. Tag nrho cov khoom tuab yog feem ntau 4, 6, 8 lossis 10 mm, tsis tshua muaj 12 lossis 16 mm. Nyob ntawm qhov tuab ntawm daim lintels, sq. m ntawm cov khoom hnyav ntawm 0.8 txog 1.7 kg. Ntawd yog, nrog tus qauv qhov ntev ntawm 2, 1x6 m, daim ntawv hnyav los ntawm 10 txog 21.4 kg.
• 3H (P3S) Yog 3-txheej vaj huam sib luag nrog cov duab plaub. Muaj nyob rau hauv tuab 10, 12, 16, 20, 25 hli. Tus txheej txheem tuab ntawm daim ntaub sab hauv yog 0.4-0.54 hli. Qhov hnyav ntawm 1 m2 ntawm cov khoom yog los ntawm 2.5 kg.
• 3 X (K3S) - peb txheej vaj huam sib luag, sab hauv uas muaj ob qho ncaj thiab ntxiv rau qhov ua kom nruj, vim tias cov cell tau txais cov duab peb tog, thiab cov khoom siv nws tus kheej - ntxiv tiv thaiv kev nyuab siab hauv kev sib piv nrog cov ntawv "3H". Cov ntawv tuab tuab - 16, 20, 25 hli, qhov hnyav tshwj xeeb - los ntawm 2, 7 kg / m2. Lub thickness ntawm lub ntsiab stiffeners yog hais txog 0.40 hli, ntxiv rau - 0.08 hli.
• 5N (P5S) - vaj huam sib luag suav nrog 5 txheej yas nrog ncaj txhav txhav. Raug tuab - 20, 25, 32 hli. Kev nqus tshwj xeeb - los ntawm 3.0 kg / m2. Lub thickness ntawm daim iav sab hauv yog 0.5-0.7 hli.
• 5 X (K5S) - 5-txheej vaj huam sib luag nrog kab rov tav thiab kab pheeb ces kaum sab hauv. Raws li tus qauv, daim ntawv muaj tuab tuab 25 lossis 32 hli thiab qhov hnyav tshwj xeeb ntawm,3, 5-3, 6 kg / m2. Lub thickness ntawm cov lintels tseem ceeb yog 0.33-0.51 hli, inclined - 0.05 hli.

Ua ke nrog cov qib qib raws li GOST, cov tuam ntxhab feem ntau muab lawv tus kheej tsim, uas tej zaum yuav muaj cov qauv uas tsis yog tus qauv ntawm tes lossis cov yam ntxwv tshwj xeeb . Piv txwv li, cov vaj huam sib luag tau muab nrog qhov muaj zog tiv taus ntau dua, tab sis tib lub sijhawm sib dua hauv qhov hnyav dua li cov qauv xaiv. Ntxiv nrog rau cov npe hwm, muaj, ntawm qhov tsis sib xws, kev hloov pauv ntawm lub teeb hom - nrog txo qhov tuab ntawm cov tawv tawv. Lawv pheej yig dua, tab sis lawv qhov kev tiv thaiv kev nyuab siab qis dua li ntawm cov ntawv raug. Ntawd yog, qib los ntawm cov tuam txhab sib txawv, txawm tias muaj cov tuab tib yam, tuaj yeem sib txawv hauv lub zog thiab kev ua haujlwm.

Yog li ntawd, thaum yuav khoom, qhov no yuav tsum raug coj mus rau hauv tus account, qhia meej nrog cov chaw tsim khoom tsis tsuas yog cov tuab, tab sis txhua tus yam ntxwv ntawm cov ntawv tshwj xeeb (ntom ntom, tuab ntawm cov tawv tawv, hom cell, thiab lwm yam), nws lub hom phiaj thiab tso cai rau thauj khoom.

Qhov ntev ntawm cov khoom siv monolithic

Monolithic (lossis molded) polycarbonate los ua daim ntawv yas yas. Tsis zoo li honeycomb, lawv muaj cov qauv sib xws kiag li, tsis muaj voids sab hauv. Yog li ntawd, qhov ntsuas qhov ntsuas ntawm cov vaj huam sib luag monolithic yog qhov siab dua, feem, qhov ntsuas siab dua, cov khoom siv tuaj yeem tiv taus cov khoom siv hnyav thiab hnyav (tiv taus rau qhov hnyav hnyav - txog 300 kg ib sq. M, poob siab tsis kam - 900 txog 1100 kJ / sq. M). Xws li lub vaj huam sib luag tsis tuaj yeem tawg nrog rauj, thiab txhawb ntxiv los ntawm 11 hli tuab tuaj yeem tiv taus lub mos txwv. Ntxiv mus, cov yas no hloov tau yooj yim dua thiab pob tshab dua cov qauv. Qhov tsuas yog qhov uas nws tsis zoo rau lub xov tooj ntawm tes yog nws cov khoom kub-insulating.

Monolithic polycarbonate nplooj ntawv tau tsim raws li GOST 10667-90 thiab TU 6-19-113-87. Cov neeg tsim khoom muab ob hom ntawv los xij

• Tiaj - nrog lub tiaj, du nto.
• Profiled - muaj qhov corrugated nto. Lub xub ntiag ntawm kev ntxiv txhav txhav txhav (corrugation) ua rau cov khoom siv ruaj dua li daim ntawv tiaj tus. Cov duab ntawm cov ntaub ntawv tuaj yeem yog ntais los yog trapezoidal nrog qhov siab ntawm qhov profile (lossis nthwv dej) nyob rau thaj tsam ntawm 14-50 mm, qhov ntev ntawm corrugation (lossis yoj) los ntawm 25 txog 94 mm.

Hauv qhov dav thiab ntev, cov ntawv ntawm ob qho tib si tiaj tus thiab profiled monolithic polycarbonate los ntawm cov tuam ntxhab feem ntau ua raws li tus qauv dav dav:

• dav - 2050 hli;
• ntev - 3050 hli.

Tab sis cov khoom kuj tseem muag nrog cov hauv qab no:

• 1050x2000 hli;
• 1260 × 2000 hli;
• 1260 × 2500 hli;
• 1260 × 6000 hli.

Cov txheej txheem tuab ntawm cov ntawv ntawm monolithic polycarbonate raws li GOST yog nyob ntawm thaj tsam ntawm 2 hli txog 12 hli (qhov loj me me - 2, 3, 4, 5, 6, 8, 10 thiab 12 mm), tab sis ntau lub tuam txhab muab dav dua ntau yam - los ntawm 0.75 txog 40 hli.

Txij li cov qauv ntawm txhua nplooj ntawv ntawm cov yas monolithic zoo ib yam, tsis muaj voids, nws yog qhov loj me ntawm ntu ntu (uas yog, tuab) uas yog qhov tseem ceeb cuam tshuam rau lub zog (qhov nyob hauv cov khoom siv ntawm tes, lub zog muaj zog nyob ntawm tus qauv sab hauv).

Qhov tsis tu ncua ntawm no yog tus qauv: hauv kev faib ua feem rau qhov tuab, qhov ntom ntawm lub vaj huam sib luag nce, feem, lub zog, tiv taus kom thim rov qab, siab, thiab kev tawg . Txawm li cas los xij, nws yuav tsum raug coj mus rau hauv tus account tias nrog rau cov ntsuas no, qhov hnyav kuj nce ntxiv (piv txwv li, yog 1 square meter ntawm 2-mm vaj huam sib luag hnyav 2.4 kg, tom qab ntawd 10-mm vaj huam sib luag hnyav 12.7 kg). Yog li ntawd, cov vaj huam sib luag muaj zog tsim lub nra hnyav rau cov qauv (hauv paus, phab ntsa, thiab lwm yam), uas yuav tsum tau teeb tsa lub thav duab thav duab.

Dabtsi yog khoov vojvoog txog kev tuab

Polycarbonate tsuas yog cov khoom siv vov tsev uas, nrog lub zog ntsuas tau zoo, tuaj yeem tsim tau yooj yim thiab khoov hauv lub xeev txias, ua cov duab zoo nkauj . Txhawm rau tsim cov kab hluav taws xob zoo nkauj (arches, domes), koj tsis tas yuav sib sau ua ke saum npoo av los ntawm ntau qhov tawg txawm tias - koj tuaj yeem khoov cov polycarbonate panels lawv tus kheej. Qhov no tsis xav tau cov cuab yeej tshwj xeeb lossis cov xwm txheej - cov khoom tuaj yeem tsim los ntawm txhais tes.

Tab sis, tau kawg, txawm tias muaj lub siab elasticity ntawm cov khoom, txhua lub vaj huam sib luag tuaj yeem khoov tsuas yog rau qee qhov txwv. Txhua qib ntawm polycarbonate nws muaj nws qib kev hloov pauv. Nws yog tus yam ntxwv tshwj xeeb - khoov vojvoog. Nws nyob ntawm qhov ntom ntom thiab tuab ntawm cov khoom. Cov qauv yooj yim tuaj yeem siv los xam lub vojvoog khoov ntawm cov txheej txheem ntom ntom.

• Rau monolithic polycarbonate: R = t x 150, qhov twg t yog daim ntawv tuab.
• Rau daim ntawv honeycomb: R = t x 175.

Yog li, hloov tus nqi ntawm daim ntawv tuab ntawm 10 hli rau hauv cov qauv, nws yooj yim los txiav txim siab tias txoj kab uas hla ntawm ib daim ntawv monolithic ntawm qhov muab tuab yog 1500 hli, yam ntxwv - 1750 hli. Thiab noj cov tuab ntawm 6 hli, peb tau txais qhov tseem ceeb ntawm 900 thiab 1050 hli. Txhawm rau kom yooj yim, koj tsis tuaj yeem suav txhua lub sijhawm koj tus kheej, tab sis siv cov lus npaj npaj ua. Rau cov khoom lag luam uas tsis yog txheej txheem ntom ntom ntom ntom ntom ntom ntom yuav txawv me ntsis, yog li ntawd, ua ntej yuav khoom, koj yuav tsum tau txheeb xyuas qhov no nrog tus tsim khoom.

Tab sis rau txhua hom khoom siv muaj cov qauv meej: daim ntawv nyias nyias, zoo dua nws khoov .… Qee hom ntawv los txog 10 hli tuab yog li yoog raws tau tias lawv tuaj yeem rub mus rau hauv ib lub yob, uas yooj yim heev rau kev thauj mus los.

Tab sis nws yog ib qho tseem ceeb kom nco ntsoov tias dov polycarbonate tuaj yeem khaws cia rau lub sijhawm luv; thaum lub sijhawm khaws cia ntev, nws yuav tsum nyob hauv daim ntawv tiaj tus thiab nyob hauv txoj haujlwm kab rov tav.

Kuv yuav tsum xaiv qhov loj me?

Polycarbonate raug xaiv raws li cov dej num twg thiab nyob hauv cov xwm txheej twg nws tau npaj los siv cov khoom siv . Piv txwv li, cov khoom siv rau sheathing yuav tsum muaj lub teeb yuag thiab muaj cov cua sov zoo, rau lub ru tsev nws yuav tsum muaj zog heev kom tiv taus cov daus. Rau cov khoom uas muaj lub ntsej muag nkhaus, nws yog qhov yuav tsum tau xaiv cov yas nrog qhov xav tau yooj yim. Cov tuab ntawm cov khoom raug xaiv nyob ntawm seb qhov hnyav yuav hnyav npaum li cas (qhov no tshwj xeeb tshaj yog rau lub ru tsev), ntxiv rau ntawm cov kauj ruam ntawm lub lathing (cov khoom yuav tsum tau muab tso rau ntawm tus ncej). Qhov ntau dua qhov kwv yees qhov hnyav, daim ntawv tuab yuav tsum yog. Ntxiv mus, yog tias koj ua lub crate ntau dua, tom qab ntawd cov tuab ntawm daim ntawv tuaj yeem siv tsawg dua.

Piv txwv li, rau cov xwm txheej ntawm txoj kab nruab nrab rau txoj kab me me, qhov kev xaiv zoo tshaj plaws, suav nrog cov daus daus, yog cov ntawv monolithic polycarbonate nrog cov tuab ntawm 8 hli nrog lub suab lathing ntawm 1 m. Tab sis yog tias koj txo cov lathing suab mus rau 0.7 m, tom qab ntawv 6 hli tuaj yeem siv tau. Txog kev suav, qhov ntsuas ntawm qhov xav tau lathing, nyob ntawm qhov tuab ntawm daim ntawv, tuaj yeem pom los ntawm cov lus sib dhos. Thiab txhawm rau txiav txim siab kom raug daus thauj rau koj thaj av, nws yog qhov zoo tshaj los siv cov lus pom zoo ntawm SNIP 2.01.07-85.

Feem ntau, kev suav tus qauv, tshwj xeeb tshaj yog cov qauv tsis zoo, tuaj yeem nyuaj heev. Qee lub sij hawm nws yog qhov zoo dua los tso nws rau cov kws tshaj lij, lossis siv cov haujlwm tsim kho. Qhov no yuav tiv thaiv kev ua yuam kev thiab tsis tsim nyog pov tseg cov khoom.

Feem ntau, cov lus pom zoo rau xaiv cov tuab ntawm polycarbonate panels tau muab raws li hauv qab no

• 2-4 hli - yuav tsum raug xaiv rau cov qauv hnyav uas tsis muaj qhov hnyav: kev tshaj tawm thiab cov qauv zoo nkauj, cov qauv tsev cog khoom hnyav.
• 6-8 hli - cov vaj huam sib luag ntawm cov tuab tuab, ntau yam zoo heev, tau siv rau cov qauv tsim muaj qhov hnyav nruab nrab: lub tsev cog khoom, tso, gazebos, canopies. Yuav siv tau rau cov vov tsev me me nyob rau thaj tsam uas muaj cov daus qis.
• 10 -12 hli - zoo haum rau kev tsom iav ntsug, tsim cov laj kab thiab laj kab, tsim kho cov teeb meem tsis muaj suab nrov ntawm txoj kev loj, khw lub qhov rais, lub qhov rooj thiab lub ru tsev, pob tshab pob tshab ntxig rau hauv cov cheeb tsam uas muaj cov daus nruab nrab.
• 14-25 hli - muaj lub zog zoo heev, tau txiav txim siab "ua phem pov thawj" thiab tau siv los tsim lub ru tsev translucent ntawm thaj chaw loj, ntxiv rau qhov txuas ntxiv mus tas li ntawm cov chaw ua haujlwm, tsev cog qoob loo, lub vaj lub caij ntuj no.
• Los ntawm 32 hli - siv rau kev ua haujlwm vov tsev hauv thaj tsam uas muaj daus siab.
