Standard osayizi slabs

Designs yokuvala amadivayisi phakathi izibuya isakhiwo esakhiwayo - ke sigcizelelwa ukhonkolo. Zenziwa ne admixtures obuphathekayo eziningi amamaki esindayo, engasindi izinhlobo kwesakhiwo obuphathekayo isakhiwo obukhulu, kanye kwagcizelela silicate ukhonkolo. Ukusetshenziswa eyinhloko setshe phansi kuyinto ekwakhiweni ingxenye obusekelayo obubonisa ukuba izindiza ovundlile zezakhiwo ezinkulu. Inkokhelo ku umkhiqizo kumele singeqi 6 kwezinkambiso KPA enqunyiwe, kuyilapho isisindo isakhiwo akubhekwa. Ukunqwabelanisa ka eziyize core slabs kumele kwenziwe base (odongeni) at ibanga okungenani 150-200 mm enikeziwe njalo ukuthi ukusekelwa kunamandla umkhiqizo ngokwayo.

Phakathi izinhlobo ezinkulu izakhiwo ukuze kwakhiwe ukugqagqana kukhona okulandelayo:

• PPP - threaded enezisekelo zikakhonkolo;
• noma Korytnyi ribbed iphrofayli;
• eziyize (core eziyize);
• Monolithic.

Ukumaka core eziyize kusho lokhu okulandelayo:

• 1H - ukhonkolo olulodwa-ungqimba isakhiwo nge ekuphakameni 120 mm;
• 2P - uhla efanayo, kodwa of ukushuba ngaphezulu (160 mm);
• 1CO - core eziyize (220 mm), ngaphakathi okuyinto kukhona voids nge round ububanzi 159 mm;
• 2CO - plate esifanayo, ububanzi we izimbotshana - 140 mm;
• PB - core ozwakala nge ekuphakameni 220 mm, indlela ukwakha - ngaphandle formwork.

core slabs eziyize kabani Ubukhulu kukhona ngaphakathi ejwayelekile, ihlala omunye imininingwane ukwakhiwa elula kunazo. Basuke bangaveziwe nomlilo, ngeke ukubola, kukhona okuhlala ngokwedlulele futhi enokwethenjelwa, amelana umswakama.

Ubukhulu slabs aqukethe kwemigomo a parallelepiped, ngaphakathi okuyinto kukhona voids ngesimo amashubhu cylindrical. Ukuba khona lezi zitsha unika ukuqina design emuzini eguqa, okwenza kube nokwenzeka ukuba kukhishwe imithwalo esindayo. Ngaphezu kwalokho, imigodi lula kakhulu inqubo laying ngaphakathi kubo konke ukuxhumana kungenzeka ngesikhathi kwakhiwa isakhiwo.

Standard izilinganiso slabs - isiqinisekiso esiqinile izindleko eyanele imikhiqizo ukhonkolo. Nokho, umklamo kanye Ubukhulu ngale evamile kungadalwa ngokuvumelana imidwebo ngabanye. Nakuba kunjiniyela ukonga ukuhlinzeka kangcono isicelo ezinobukhulu normative ngenxa yezindleko ephakeme yokukhiqiza izingqimba angajwayelekile ngenxa izindleko ezengeziwe.

Ubukhulu esivamile slabs nge voids bakha nobude ku ezahlukene 2.4 kuya 6.6 m, kuye ngokuthi lwemibhalo okwesikhathi imikhiqizo ejwayelekile chungechunge. ububanzi ejwayelekile kungenzeka 0.6 - 2.4 m ngezikhawu pitch ezahlukene. Ukuphakama (ukujiya) amapuleti kuthathwe ezingeni 220 mm, futhi isisindo ingqikithi yonke imikhiqizo kuze kube 2.5 tonnes.

Ubukhulu slabs eziyize-uhlobo PC lubhalwe ngemfihlo ku kophawu lomkhiqizo ngamunye, futhi ukuqonda kwabo ukuba ngakho, isibonelo, i-PC 72.15-8:

• PC kusho lokhu okulandelayo: eziyize-core esinombhalo izimbotshana round nge ububanzi 159 mm, 220 mm umkhawulo okusezingeni eliphezulu, izinhlangothi zombili kuyizingane beyizinsika;
• 72 - obuphelele e decimeters umkhiqizo (ngamanye amazwi, ngamamilimitha - 7180);
• 15 - ububanzi e decimeters (noma ibalwa 1500 mm);
• 8 - umthwalo ezingamelana nezinselele isitofu, e-KPA.
