Kuma daminɛ: Plywood jɔlen jɔyɔrɔ bi jɔli la
Structural plywood ye jiriw ye minnu bɛ kɛ ni ɛntɛrinɛti ye minnu bɛ kɛ ka caya jɔli ni izini baara la. A dabɔra walasa ka fanga, hakɛ sabatili, ani doni{1}}ta baarakɛcogo di, a jɔyɔrɔ ka bon kosɛbɛ sigiyɔrɔw ni jagokɛyɔrɔw jɔcogo fila bɛɛ la.
A tɛ i n’a fɔ pankurun masirilenw, jirisunw jɔcogo bɛ jateminɛ fɔlɔ ka da masinw cogoya kan, u sirili kɛcogo kan, ani jɔli sariyaw labatoli kan. Ni jɔli fɛɛrɛw bɛ ka taa ɲɛ diɲɛ kɔnɔ, jɔli plywood bɛ to ka kɛ jusigilan ye sugu caman kɔnɔ.
Nin barokun in bɛ baarakɛlaw ka ɲɛfɔli kɛ plywood jɔcogo kan, k’a sinsin a dabɔcogo kan, a danfara, a kɛcogo, ani a kɛcogo lakikaw-diɲɛ kɔnɔ.
1. Structural Plywood ye mun ye?
Structural plywood ye panneau ye min dilannen don ni injiniyɛri ye min dilannen don ni jiribolo caman sirili ye ɲɔgɔn na ni nɛgɛ ye funteni ni degun kɔrɔ. A ka c’a la, finimuguw bɛ labɛn ka kɛ layini hakɛ gansan ye, ni layini kɛrɛfɛtaw ka suman sira ɲɛsinnen bɛ ɲɔgɔn ma.
Nin cross-laminated structure in bɛ fanga bonya, ka dimensions lamagacogo dɔgɔya, ani ka kari ni warping kɛlɛli ɲɛ doni kɔrɔ.
Structural plywood dilannen don kɛrɛnkɛrɛnnenya la walasa ka doni-ta ni muɲuli wajibiyalenw dafa minnu ɲɛfɔlen don jamana walima diɲɛ sariyaw fɛ.
2. Veneer jɔcogo ani a kɔnɔna cogoya
2.1 Kurucɛ-Laminiw jɔli
Plywood jɔcogo ɲɛfɔli ye a cross-laminated veneer jɔcogo ye:
Layɛrɛw ni jateden gansan-(3-ply, 5-ply, 7-ply, wdfl)
Sumanw ɲɛsincogo ɲɔgɔn falen-falen
Panɛli jɔli balansi
O dilancogo in bɛ degunw tilatilali cogo kelen na ani ka kɔrɔta fanga ɲɛ ka taa a fɛ fan fila bɛɛ fɛ.
2.2 Lɔgɔ suguya minnu bɛ kɛ ka caya
Structural plywood bɛ se ka dilan ni jiri gɛlɛnw walima jiri nɔgɔlen suguyaw ye, ka kɛɲɛ ni marabolow ka sɔrɔ ye ani a kɛcogo wajibiyalenw.
Lɔgɔ nɔgɔlen suguya minnu ka teli ka sɔrɔ olu ye:
Pine (Pine) ye
Spruce (Spruce) ye
Fir
Larch ye
Lɔgɔ gɛlɛn suguya minnu ka teli ka sɔrɔ olu ye:
Poplar (Poplaire) ye
Birch (Birch) ye
Lɔgɔ gɛlɛnw ɲagaminen minnu bɛ yɔrɔw la minnu ka timi
Suguda sugandili bɛ nɔ bila panɛli laban ka density (dakun), fanga ani girinya cogoyaw la.
3. Adhesive Systems ani Bonding baarakɛcogo
Nɔrɔli baarakɛcogo ye fɛnba ye min bɛ kɛ sababu ye ka plywood jɔcogo ɲuman jira.
Nɔrɔlan minnu bɛ kɛ tuma caman na olu ye:
Fenɔli-fɔrmadehidi (PF) ye kɛnɛma-kala plywood ye
Melamine-urea-formaldehyde (MUF) min bɛ kɛ ka kɛnɛyako tilancɛ-kɛ
Ureya-formaldehyde (UF) min bɛ kɛ kɔnɔna na
A ka c’a la, kɛnɛma jɔli plywood bɛ ji{0}}minɛn min tɛ se ka tobi walima min tɛ tobi-, o de wajibiya walasa ka a to a ka mɛn waati jan kɔnɔ sigida cogoya caman na.
4. Danfara ka kɛɲɛ ni baarakɛcogo ni baarakɛcogo ye
Structural plywood bɛ se ka tila ka kɛɲɛ ni baarakɛcogo laɲininen ye:
4.1 Kɔnɔnafɛnw jɔcogo Plywood
A dabɔra sigida jalenw kama, minnu bɛ kɔlɔsi
A bɛ kɛ duguma dacogo la, kogow datugucogo la, ani mebɛriw jɔcogo la
4.2 Kɛnɛma jɔcogo Plywood
A dilannen don ni nɔrɔfɛnw ye minnu bɛ se ka waati{0}} kɛlɛ
A bɛnnen don so sanfɛlan, foroko, ani kɛnɛma kogow sigicogo ma
4.3 Kɔgɔjida ni kun kɛrɛnkɛrɛnnen-Kunnafoni sigicogo Plywood
Bonding ni veneer jogo bonyalen don
A bɛ kɛ sigidaw la minnu ka nɛnɛ ka bon-nɔgɔ walima doni{1}}yɔrɔ gɛlɛnw na
5. Masinaw ka baarakɛcogo ani baarakɛcogo
Baarakɛcogo jiralan jɔnjɔn minnu bɛ kɛ ka ɲɛsin plywood jɔcogo ma, olu ye :
Module de élasticité (MOE) ye .
Module de rupture (MOR) .
Sɔgɔsɔgɔninjɛ fanga
Screw-minɛ seko
Muɲuli muɲuni ani panɛli flakɛli
Fɛn dilanni ni jogoɲini sabatili nafa ka bon walasa ka baara kɛcogo dafalen sabati jɔli baara la.
6. Plywood jɔcogo minnu bɛ kɛ tuma caman na
Structural plywood bɛ kɛ ka caya iziniw kɔnɔ, i n’a fɔ:
Dugukolo sigicogo ani duguma-dakunw
Kogo ni so sanfɛlanw dacogo
Beton foroko dilanni
Foroko ni izini crating
Waati dɔɔnin jɔli ni sɛgɛsɛgɛlikɛlanw
A ka baarakɛcogo caman b’a kɛ fɛn ye min ka di kosɛbɛ jɔli siraw la minnu bɛ kɛ tuma bɛɛ ani minnu bɛ kɛ waati dɔɔnin kɔnɔ.
7. Sariyaw ni seereyaw
Ka kɛɲɛ ni sugu laɲinitaw ye, jirisunw jɔcogo bɛ se ka sariyaw labato i n’a fɔ:
EN sariyaw (Erɔpu) .
APA / PS sariyaw (Amerika woroduguyanfan) .
AS/NZS sariyaw (Ɔsitarali ani Zelande kura) .
Seereyaw b’a to panɛriw bɛ baarakɛcogo, lakana ani sigidako wajibiyalenw dafa minnu ɲɛfɔlen don.
Kuncɛli: Fɛn min bɛ se ka da a kan walasa ka jɔli baara kɛ
Structural plywood bɛ ka taa a fɛ ka kɛ fɛn jɔnjɔn ye bi jɔli la k’a sababu kɛ a fanga, a sabatili, ani a bɛ se ka ladamu. Ni a ɲɛfɔra ka ɲɛ ani ni a dilannen don, a bɛ balansi dafalen di baarakɛcogo ni baarakɛcogo ɲuman cɛ.
Ikomi sow jɔcogo bɛ ka sinsin kosɛbɛ muɲuli, lakana ani sabatili kan, jɔli plywood tora fɛn nafamaba ye jiriw ɲɛnabɔcogo la minnu dilannen don ni ɛntɛrinɛti ye.
