Pehea e koho ai i ka papahele kila? Haku i keia mau ano nui

ʻO ka papahele kila ka mea nui o ka ʻōnaehana papahele mahale kūkulu kila. Ma ke ʻano he ʻano o ka pepa kila profiled no ke kūkulu ʻana, hāʻawi ia i kahi hoʻonā formwork-free a propping-free no nā papa papa lepo. Hoʻowili ʻia ʻo ia e ka pelu anu me ka ʻano V, ʻano U a i ʻole trapezoidal corrugated cross-sections. Hoʻonohonoho ʻia kāna helu kumu hoʻohālike e like me: prefix ("YX" a i ʻole "YXB") + kiʻekiʻe hawewe-ʻākea ākea kūpono. ʻElua mau ʻōnaehana hoʻonohonoho nui: ʻo ka papahele kila maʻamau i hoʻopaʻa ʻia (open-type, re-entrant-type, closed-type) a me ka hoʻoheheʻe ʻana i ka papahele pahu kila.

Hana ʻia ka papahele papahele profiled-steel me nā ʻāpana kila galvanized. Hoʻomoe pololei ʻia ma luna o nā kaola kila a hoʻopaʻa paʻa ʻia i nā kaola kila e nā studs e komo i loko o nā ʻāpana kila. Hiki iā ia ke halihali i ke kaumaha o ka pulu a me nā ukana hana. Wahi a nā ʻano ʻāpana ʻāpana, hiki ke hoʻokaʻawale ʻia i loko o ka decking papahele ʻano open-type, re-entrant (dovetail-type) floor decking a pani ʻia-type floor decking.

ʻO ka papahele ʻano hāmama

Loaʻa iā ia nā ʻāpana V-like a i ʻole trapezoidal open cross-section. Hoʻohana wale ia ma ke ʻano he formwork mau loa i ka wā o ke kūkulu ʻana, me nā mea maikaʻi o ka hoʻonohonoho pono ʻana, ke kumu kūʻai haʻahaʻa a me ka māhele mākeke kiʻekiʻe.

Hoʻokomo hou (Dovetail-Type) Decking papahele

Hoʻohana ʻo ia i kahi ʻāpana keʻa dovetail. ʻOi aku ka haiki o kona puka lalo ma mua o ka decking ʻano hāmama, kahi e hiki ai ke hoʻopaʻa ʻia me ka mīkini. Aia kona waiwai nui i ka hoʻomaikaʻi ʻana i ke ahi a me ka hana anti-corrosion.

Paʻa-ʻAno Papa Decking

ʻO ia ke ʻano i hoʻohana nui ʻia me ka hoʻokō piha maikaʻi loa i kēia manawa. Ua pani piha ʻia kona ʻāpana keʻa i hiki ke hoʻopaʻa piha ʻia e ke kaʻa. Hōʻike ia i nā pono kumu o ka helehelena maʻemaʻe a me ka maikaʻi a me ka hana composite maikaʻi loa.

Paʻa Paʻa Paʻa Paʻa Paʻa

Ua hana mua ʻia nā pahu kila i loko o ka hale hana a hoʻohui pū ʻia me nā ʻāpana kila profiled galvanized. ʻO kona ʻokoʻa nui mai ka papahele hoʻopaʻapaʻa profiled-steel maʻamau aia ma ka ʻāpana haʻahaʻa. ʻO ka mea mua e hiki ai i kāna mau mea ʻelua ke hana i kēlā me kēia hana, ʻoiai ka mea hope e ʻike i ke kumu ʻelua o ka mea hoʻokahi. Hāʻawi ka papahele ʻohu hao kila i ka māhele hana, ʻoi aku ka hilinaʻi o ka hana, a me ka maʻalahi o ka mana maikaʻi. ʻO ka ʻokoʻa, ʻoi aku ka nui o ka hoʻopaʻa ʻana o kēlā me kēia ʻāpana.

ʻO ke koho ʻana i ka papahele papahele e pili ana i ka noʻonoʻo kūpono ma waena o ka span, ka ukana, ka hana kūpono, a me ke kumukūʻai holoʻokoʻa. Ma waena o nā ʻano like ʻole, ʻo ka decking open-type ka haʻahaʻa loa; Hāʻawi ka decking hou i ke ahi a me ka pale ʻana i ka corrosion; Hāʻawi ka decking ʻano pani i ka hana piha maikaʻi loa; a me nā mea hoʻoheheʻe kila-bar truss e hōʻike ana i ka hana kiʻekiʻe a me ka mana maikaʻi.
