1. Construction preparation
Siminti: Simintin Portland na yau da kullun sama da No. 325 should be used, or Portland slag cement can also be used. Lokacin da akwai matsananciyar matsananci, it should be selected according to the design requirements.
Yashi: Yi amfani da yashi matsakaici, which must not contain debris. The mud content must not exceed 3%, and it must be passed through a 3-5mm sieve before use.
Main equipment: injin kumfa, turmi mixer, baƙin ƙarfe, broom, katako trowel, scraper, da dai sauransu.
2. Maganin Layer: clean up and sweep the debris, and moisten it with water.
3. Preparation and use of foam
The foam used in foam concrete should be prepared with a special cement foaming machine. The diameter of the foam should be controlled between 0.5-2mm, and it should be elastic and not easily broken. The concrete foam should be prepared and used, and the retention time should not be longer than 20 mintuna.
4. Ya kamata a gina matakan daidaitawa da rufin rufi a lokaci guda.
Ya kamata gangara na rufin rufi ya dace da buƙatun ƙira. Haɗin kai tsakanin tushe mai tushe da tsarin rufin da ke fitowa (parapet, gaba, bangon sararin sama, nakasar haɗin gwiwa, bututun hayaki, da dai sauransu.) and the corner of the base layer, da rufin rufi Duk ya kamata a sanya shi a cikin madauwari baka; Ya kamata a sanya matakin daidaitawa a cikin rami mai ƙasa kaɗan a kusa da digon ruwa na magudanar ruwa na ciki.
5. When the total thickness exceeds 10cm, it should be constructed in layers.
6. Use structure to find slope for flat roof, and the slope should not be less than 3%; use material to find slope, kuma gangara ya kamata 2%; don gutter da eaves don samun gangara a tsayi, the slope should not be less than 1%, and the water drop at the bottom of the ditch should not exceed 150mm .
Precautions for foam concrete roof insulation construction:
1. Lokacin da yawa ya kasance ƙasa da 300kg/m3, the accelerator should be used during construction. Yawan totur yana gabaɗaya 2%-8% of the cement amount. The amount of accelerator should increase or decrease according to the type of accelerator, construction temperature and engineering requirements. The specific increase or decrease should be determined by experiment.
2. The temperature at the construction site should not be lower than 5℃.
3. After construction, ya kamata a danshi kuma a kiyaye shi.
Siffofin kumfa kankare rufin rufin:
1. Thermal rufi: Matsakaicin zafin jiki shine 0.080-0.16W /(m ·k), kuma thermal juriya ne game da 20-30 sau na talakawa kankare.
2. Mai nauyi: Matsakaicin busassun busassun shine 300-700kg/m3, wanda shine 1/5-1/8 na yawa na talakawa kankare, wanda zai iya rage nauyin ginin gaba ɗaya.
3. Integrity: on-site pouring construction is closely integrated with the main project, ba tare da gibba na iyaka da bututun iska ba.
4. Sound insulation: Foam concrete contains a large number of independent bubbles, kuma ana rarraba su daidai gwargwado. Ƙarfin ɗaukar sauti shine 0.09-0.19%, wanda shine 5 sau na talakawa kankare, and it has an effective sound insulation function.
5. Compressive resistance: Ƙarfin matsawa shine 0.3-2.2Mpa.
6. Juriya na ruwa: relatively independent closed bubbles and good integrity, ta yadda ya samu wani aikin hana ruwa.
7. Anti-crack: low shrinkage rate, crack resistance is 8 sau na talakawa kankare.
8. Dorewa: daidai da rayuwar babban aikin.
9. Simple construction: babu buƙatar samun gangara don rufin lebur.
10. Economy: 20-50% lower than the comprehensive cost of other roof insulation materials.
