Second, the main equipment:
The main tools include: portable electric mixer, mixing drum (diameter 60-70cm, height 65-80cm), leveling tools, level, scraper, size trowel and ash board, roller, keg, etc.
3. Operating conditions:
1.The base layer has been cleaned up and passed the acceptance of the concealed project.
2.The tools used for this sub-project are ready.
Fourth, the operation process:
1.Process.
Roof scraping putty process: grassroots acceptance, grassroots cleaning, punctuation of the bottom elastic line of the structural slab, leveling of the yin corners around the roof, partial leveling of the roof, full scraping of putty, polishing, full scraping of the surface layer of putty, sweeping the tail and trimming the head.
The process flow of wall scraping putty: grassroots acceptance, grassroots cleaning, reserved sticker line, full scraping putty, grinding surface layer putty, full scraping, plastering construction, sweeping the tail and trimming the head.
Latex paint (light yellow melamine paint) construction process:
wall) base acceptance, base cleaning, batch 4-6 thick anti-crack mortar, two layers of alkali-resistant plastic-coated glass fiber mesh cloth are pressed into the middle, a full batch of flexible putty, a full batch of flexible putty, a grinding of silicone rubber elastic primer, the first time of emulsion brushing, recovering putty, the second time of latex paint (light yellow melamine paint) brushing, cleaning and trimming.
Ceiling) base acceptance, base cleaning, structural slab bottom line punctuation, roof around the yin corner leveling, roof local leveling, full scraping putty, grinding, surface layer putty full scraping, grinding, the first time milk brushing, recovering putty, the second time latex paint brushing, cleaning and repairing.
2.Construction technology.
Grassroots cleaning: remove the original decorative layer of the ceiling and wall to expose the substrate;
Check the wall substrate, and remove the hollow and cracked substrate plastering layer;
If the flatness of the substrate after removal is poor, mortar leveling should be used
Grassroots acceptance: the surface of the grassroots acceptance should be kept smooth and clean, no floating sand, oil stains, the surface of the uneven parts should be flattened and made up for the parts that are too convex, the scaffolding eye should be blocked tightly and smoothed, the plumbing and ventilation pipes through the wall or ceiling pipes, switch boxes, and other parts must be plugged with mortar and cleaned up, check whether the wall plastering layer has hollowing, cracking, vertical, flat and square yin and yang corners and other defects, if there are defects, they will be corrected in time.
Before the roof is batched, the straight control line must be bounced on the wall of the dark corner of the roof to ensure that the surrounding yin corner is smooth and straight, and each room must have five points to control the elevation. There must be no elevation difference and no water waves. Pop up the control line of the footing on the wall and paste the masking paper.
The roof batch ash is first leveled with a 500mm large trowel on the surrounding yin corners and the height of the board surface according to the elastic control line, and if the height difference is greater than 8mm, the anti-cracking mortar is used to level it many times, and the width of the yin angle is not less than 500mm in the direction of the roof, and the yin and yang corners of all beams and columns are rectified with white cement.
The ceiling and wall plaster must be constructed with a large slab of more than 50mm, and the thickness of the first batch of ash of the roof is controlled at 2-3mm, and the construction is carried out in turn parallel to the long side of the room. The second surface layer putty construction must wait for the bottom layer of putty to be completely dry and polished after the construction, the thickness of the surface layer is controlled at 1-2mm, parallel to the short side of the room direction with a large plate for full batch, and at the same time, when the putty is dry 6-7 layers, it must be calendered with a rubber scraper to ensure that the surface layer is smooth and clean, the texture is straight, and the color is uniform.
The construction process of wall plaster and roof plaster is the same, that is, the construction direction is different, and the thickness of the wall plaster is controlled at 2-2Within 5 mm, the first time the construction is carried out in the horizontal direction, and the second time the construction is carried out in the vertical direction.
Ceiling, wall plaster in strict accordance with the above-mentioned construction process - article construction, while paying attention to the overall construction procedures, must first roof after the wall, the ceiling and the wall of the first putty batch to complete the grinding before the surface putty construction, and the surface layer putty construction to wait until the wall plastering, floor, doors and windows installation engineering can be carried out surface layer putty construction.
In the construction of the surface layer must have other professional finished product protection measures, the finished floor floor with color stripe cloth to cover and protect, door and window frames tape, etc., it is strictly forbidden to cross-contamination, all yin and yang corners must be used in the construction of the surface layer must use sharp corners of the yin and yang angle trowel calender straight, floor doors and windows yin and yang corners need to pull through the line to keep the geometric size consistent.
5. Quality standards:
1.The materials, finished products, semi-finished products, etc. required for this sub-project shall have a material qualification certificate and on-site sampling retest and test in accordance with the quality standards of the materials, and have a retest test report.
2.Putty construction of housing parts.
The surface layer of putty should be firm and firm, and the surface layer should be smooth and flat to the touch, without powder, peeling and cracking.
The surface layer of putty should be flat, and the flatness should be controlled within 2mm;The yin and yang angles are squarely controlled within 2mm;The yin and yang angles should be straight and flat, and the straightness should be controlled within 3mm, and at the same time, there should be no water waves in the yin and yang anglesThe dividing line between the footing line and the wall, the ceiling and the wall should be straight, and the straightness should be controlled within 3mm.
The baseboard is completed and then done, and the color separation is obvious during the construction of the baseboard, and the line mouth is straight.
Doors and windows, switch panels, lamps, pipes and other peripherals should be clean, without burrs, and at the same time, the floor and other professional related facilities should not be polluted. At the same time, the surface layer of latex paint shall not have pan alkali, bite color, no flow of the surface layer, no pimples, no trachoma, the whiskering should be fine, the hand touch smooth and clean the lines of this sub-project, the dividing line, yin and yang angles must be straight, the straightness is controlled within 2mm, and at the same time, there must be no lack of edges and corners, and the finished product protection of related types of work must be done.
6. Fire prevention measures and finished product protection
1.Fire prevention measures
Indoor and outdoor temporary fire hydrant systems should be set up at the construction site, and meet the fire water supply requirements for fire fighting at the construction site.
2.Finished product protection.
During the construction process, attention should be paid to the protection of the finished products of other professional facilities, such as line pipes, wire boxes, and water pipes buried in the wall.
The construction of the floor must be covered with color stripe cloth before construction can be carried out to avoid cross-contamination.
7. Issues that should be paid attention to:
1.The construction personnel should abide by the safety production and environmental protection management systems on the construction site, obey the unified management of the site, wear safety helmets when entering the site, and it is strictly forbidden to throw tools and other items up and down the construction site.
2.The scaffolding must be inspected for safety, and only after it is confirmed that it is qualified can it be boarded. The scaffold should be covered with scaffolding boards and fixed firmly, and probe boards are strictly prohibited.
3.When using hand-held power tools, a leakage protector should be set up, and insulating gloves should be worn to prevent electric shock.
4.Each process should be cleaned after the completion of the work, and the waste should be placed in the designated place.
