Fetola: Viewmate terata ea khalase e felletseng
Botenya ba khalase e sebelisoang bakeng sa litepisi (hangata bakeng salithapo tsa ho betla, lithapo tsa ho tšoara, lithapo tsa ho hatakela, kapa liphaephe tse phahamisang) ha se boleng bo tsitsitseng—ho itšetlehile ka mofuta oa khalase, ts'ebeliso (litlhoko tsa polokeho), mojaro oa sebopeho, le melao ea moaho ea lehae. Ka tlase ke tlhaloso e qaqileng ea botenya bo tloaelehileng, lintlha tsa bohlokoa, le litšupiso tsa khoutu ho netefatsa polokeho le ho latela melao:
1. Mofuta oa Khalase ea Bohlokoa bakeng sa Litepisi: E tlameha ho ba "Khalase ea Polokeho"
Ntlha ea pele,khalase eohle e sebelisoang litepising e hlokahala hore e be khalase ea polokeho(ho ya ka melao ya meaho ya lefatshe ka bophara jwalo ka US IRC, EU EN 12150, kapa GB 15763.2 ya China). Sena se thibela ho pshatleha ho kotsi hore e be dikotwana tse bohale. Mefuta e mmedi e meholo ke:
- Khalase e Halefileng (Khalase ea Polokeho e Matlafalitsoeng ke Mocheso): Khetho e tloaelehileng haholo—e matla ka makhetlo a 5 ho feta khalase e tloaelehileng, 'me e robeha likotoana tse nyane, tse bohlasoa tse kang "litaese".
- Khalase e Laminated: Mealo e 'meli kapa ho feta ea khalase e kopantsoeng le lera la polymer (mohlala, PVB). Esita le haeba e robehile, lera le tšoara likotoana sebakeng sa tsona, e leng se etsang hore e be sebaka se loketseng libaka tse kotsing e kholo (mohlala, litepisi tsa kantle, litepisi tse ka ntle).
2. Botenya ba Khalase bo Tloaelehileng ka Kopo
Botenya bo fapana haholo ho latela hore na khalase e sebedisetswabalustrade (leraele la tšireletso), sereile sa letsohokapamohatla/sephahamiso(e jarang mojaro vs. e sa jareng mojaro).
| Kopo | Mofuta oa Khalase | Mefuta e Tloaelehileng ea Botenya | Mabaka a Bohlokoa |
| Balustrade ea Litepisi (Phanele) | E bonolo / e laminated | 8mm – 12mm | Ha e jare mojaro (e hanela kgatello ya lehlakore feela, mohlala, ho sekamela). 8mm e tlwaelehile bakeng sa matlo; 10–12mm bakeng sa kgwebo (sephethephethe se phahameng sa maoto). |
| Sehatsetsi sa Litepisi | E bonolo / e laminated | 15mm – 25mm | E tlameha ho tšehetsa khatello ea letsoho (50–100N ka khoutu). Khalase e teteaneng (mohlala, 20mm) e netefatsa ho tiea le ho tšoarella. |
| Mohatla oa Litepisi (Mohato oa Khalase) | Laminated (Mealo e Bonolo) | 25mm – 40mm | E jarang mojaro: E tšehetsa boima ba motho (bonyane 500kg/m²). Hangata ho sebelisoa likhalase tse 2-3 tse halefisitsoeng (mohlala, 2x12mm + PVB = kakaretso ea 25mm) bakeng sa bolulo; 30-40mm bakeng sa khoebo. |
| Sekepe se Phahamisang Litepisi (Phanele e otlolohileng) | E bonolo / e laminated | 8mm – 10mm | Ha e jare mojaro (e le bakeng sa ponahalo feela). E tšesaane ho feta li-balustrade, kaha ha e hloke ho hanela matla a lehlakoreng. |
3. Mabaka a Bohlokoa a Amang Botenya
Kantle ho ts'ebeliso, lintlha tsena li tla etsa qeto ea botenya ba ho qetela bo hlokahalang:
- Melao ea KahoMelao ea lehae (mohlala, USKhoutu ea Machaba ea Bolulo (IRC), EUEN 13474) e laela matla le botenya bo fokolang. Mohlala, IRC e hloka litepisi tse sireletsang litepisi ho mamella matla a boima ba 200 lbs (90kg) a sebelisoang ka ho otloloha—sena se ka hloka khalase e teteaneng bakeng sa li-balustrade tse telele.
- Sekhahla (Sebaka Pakeng tsa Litšehetso): Bakeng sa diphanele tsa balustrade, di-spans tse telele (mohlala, 1.5m vs. 0.8m) di hloka khalase e teteaneng ho thibela ho kobeha kapa ho robeha. Phanele ya khalase ya 10mm e ka sebetsa bakeng sa span ya 1m, empa span ya 1.2m e ka hloka 12mm.
- Litlhoko tsa Mojaro: Lithapo tsa ho hatakela bakeng sa libaka tsa khoebo (mohlala, mabenkele a maholo, liofisi) li hloka khalase e teteaneng ho feta litepisi tsa bolulo, kaha li tlameha ho tšehetsa meroalo e matla e phahameng (mohlala, batho ba bangata, lintho tse tsamaeang ka mabili).
- Maemo a Tikoloho: Litepisi kapa litepisi tse kantle libakeng tse mongobo (mohlala, matamo a haufi le litepisi) li ka sebelisa khalase e teteaneng e nang le laminated ho thibela ho putlama le ho bola.
4. Mehlala ea Maemo
Ho etsa konkreite ena, lintlha tse tloaelehileng tsa lefats'e la nnete ke tsena:
- Balustrade ea Litepisi tsa Bolulo: Khalase e halefisitsoeng ea 10mm (bophara ba ≤1m, bolelele ba 900mm).
- Moqomo oa Khalase oa Bolulo: Khalase e laminated ea 25mm (e halefisitsoeng ke 2x12mm + 1mm PVB interlayer).
- Sehatsetsi sa Litepisi tsa Khoebo: Khalase e halefisitsoeng ea 20mm (e tšehetsa matla a 100N, bolelele ba 1.1m).
- Balustrade ea Litepisi tsa Kantle: Khalase e laminated ea 12mm (e hanela moea, pula le liphetoho tsa mocheso).
5. Tlhokomeliso ea Bohlokoa ea Polokeho
Le ka mohla u se ke ua sebelisakhalase e koahetsoeng (e tloaelehileng)bakeng sa litepisi—e robeha likotoana tse bohale, tse kotsi. Kamehla netefatsa hore khalase e netefalitsoe e le khalase ea polokeho (batla litempe tse kang “TEMPERED” kapa “LAMINATED” moeling) le hore ho kenngoa ho latela melao ea meaho ea lehae (rakonteraka ea litsebi kapa moenjiniere oa meaho o lokela ho netefatsa sena).
Ka bokhutšoanyane, botenya ba khalase ea litepisi bo tloha ho8mm (li-risers/li-balustrade)ho40mm (lithapo tsa khoebo), ka boleng bo nepahetseng bo laolwang ke ts'ebeliso, khoutu, bolelele le mojaro. Kamehla beha khalase ea polokeho pele le ho latela melao ea lehae.
