Milingo yabwino imathandiza mulimi slabs

Maselo kutseka zipangizo pakati pa mbewu ya nyumba tikukonza - izo zimakhazikika konkire. Amachita ndi admixtures konkire zingapo sukulu lolemera, opepuka structural mitundu konkire dongosolo wandiweyani, komanso analimbitsa simenti silicate. The ntchito yaikulu ya pansi slab ndi pomanga gawo akuthandiza ya ndege yopingasa a nyumba yaikulu. The payload pa mankhwala sayenera upambana 6 kPa Kwalamulidwa mchikhalidwe, pamene kulemera kwa dongosolo la si. Stacking wa slabs dzenje pakati ayenera kukhala pa maziko a (mpanda) pa mtunda wa osachepera 150-200 mamilimita anapereka zonse kuti thandizo ndi wamphamvu kuposa mankhwala yokha.

Pakati pa mitundu ikuluikulu ya nyumba mapangidwe alipo ndi zotsatirazi:

• PPP - yamazinga slabs konkire;
• kapena Korytnyi ribbed mbiri;
• dzenje (mphako pakati);
• monolithic.

Chodetsa dzenje pakati zikutanthauza zotsatirazi:

• 1h - konkire umodzi-wosanjikiza dongosolo ndi kutalika 120 mamilimita;
• 2P - osiyanasiyana chomwecho, koma makulidwe kwambiri (160 mm);
• 1CO - dzenje pachimake (220 mm), mkati limene pali voids ndi awiri ozungulira 159 mamilimita;
• 2 Akorinto - mbale chomwecho, m'mimba mwake wa cavities - 140 mamilimita;
• PB - dzenje pakati ndi msinkhu wa mamilimita 220, njira kupanga - popanda formwork.

slabs pakati dzenje amene miyeso mkati muyezo, mpaka pano zokhudza kumanga yabwino kwambiri. Iwo si poyera kuti moto, siidzaola, ndi cholimba kwambiri ndi odalirika, kugonjetsedwa ndi chinyezi.

Makulidwe slabs zigwirizana magawo a parallelepiped ndi, mkati limene pali voids mu mawonekedwe a machubu cylindrical. Pamaso pa zotengera amenewa amapereka kapangidwe stiffness mu kupinda chuma, zomwe zimathandiza kuti wachotsa katundu wolemera. Komanso, voids kwambiri atsogolere ndondomeko atagona mkati iwo kulankhulana n'kotheka pomanga nyumbayo.

Standard miyeso ya slabs - olimba chitsimikizo cha mtengo chokwanira cha mankhwala konkire. Komabe, kapangidwe ndi miyeso kupitirira alipidwa akhoza analengedwa monga mwa zojambula payekha. Ngakhale mapulogalamu ndalama bwino kupereka kwa ntchito zazikulu normative chifukwa mtengo zapamwamba kupanga mbale sanali muyezo chifukwa cha zina ndalama.

miyeso ankaikira slabs ndi voids zimapanga nthawi yaitali mu osiyanasiyana 2.4 kuti 6,6 m, malingana Directory chifukwa lililonse mankhwala angapo. Mwachizolowezi m'lifupi kungakhale 0,6 - 2.4 mamita pa intervals wa phula osiyana. Kutalika (makulidwe) mbale anatengedwa pa mlingo wa 220 mm, ndi kulemera okwana zinthu zonse kwa tonnes 2.5.

Makulidwe slabs dzenje-mtundu PC ndi encrypted mu olemba lililonse mankhwala, ndi kumvetsa kuti Mwachitsanzo, PC 72.15-8:

• PC zikutanthauza zotsatirazi: dzenje-pachimake slab ndi cavities kuzungulira ndi awiri a 159 mm, 220 mamilimita mkulu malire, onsewo ndi mizati;
• 72 - yaitali decimeters mankhwala (i.e., mu millimeters - 7180);
• 15 - m'lifupi mwa decimeters (kapena masamu 1500 mm);
• 8 - katundu chimene chingathe kupirira mbaula, mu kPa.
