Guidelines for hardbound construction of construction projects Indoor oil worker Preparations before construction: 1All the pre-buried wire boxes and boxes on the walls and roofs have completed the pre-buried installation, and the pre-buried pipe has completed the ribbon work (to ensure that the pre-buried pipe is free of blockage). 2The joint treatment between secondary structure wall and shear wall, partition board and shear wall and partition board has been completed and the special acceptance is qualified. 3The wall with plastering has been checked and accepted to ensure that there is no empty drum. 4Inside wall plastering gypsum and putty should have factory qualification certificate, manufacturer's production license, manufacturer's qualification and inspection report (including environmental protection parameters).In addition, site inspection should be carried out frequently during construction. II. Key Construction Points 1The wall plastering of the inner wall oiler construction is basically dry, and the moisture content of the base is not more than 10%. 2Threads, dots, formulas and rebounds.Before the construction of oil industry, the exit line of 120 mm indoor kicking line should be ejected in order to control the height.When scraping putty, the Yin-Yang angle should be corrected first, and the elastic line of the Yin-Yang angle should be found. After the Yin-Yang angle is corrected, the full scraping can be carried out. 3For the roof whose smoothness meets the requirements of specifications, it is required in principle that after the joints are polished and leveled, the putty should not be scraped completely, and the putty should be scraped around the roof to correct the shade angle within the 150 mm range intersecting with the shade angle.The roof with flatness not up to the standard must be treated. 3The Yin and Yang angles of all parts of the room must be made into right angles.And straight. 4The wire boxes on the walls and the periphery of the boxes must be straightened and rectified. 5During indoor oil construction, doors, windows and frames must be effectively protected. Strict and unprotected measures can cause secondary pollution. 6Layered cement mortar and wall putty are used to smooth the inner part of the indoor kick line, and 10% glue is added to the surface coated plain cement slurry. 7The junction of the wall and the shade corner of the roof returns to 20mm from the shade corner of the roof, and 10% glue is added into the above coated plain cement slurry. 8In principle, the roof does not require the scraping of putty. If the smoothness of the structure construction does not meet the requirements of the acceptance criteria, the cement putty can be scraped to repair. 9Permissible deviation of putty: Serial number 1 2 3 4 project Grade standard Leakage scratch, bottom penetration Anti-alkali and biting colour Falling, splashing Windows, lamps and lanterns Not allow Not allow Not allow clean
