Floor-except the kitchen and bathroom are floor tiles, they are all polished with fine stone concrete and cement;

Ceiling-except for the ceiling with mineral wool sound-absorbing board, all the others in the tunnel are scraped white and water-resistant putty.

2.3 Characteristics of Decoration Project The decoration materials of this project belong to the mid-range, so the quality of the materials themselves, especially the specifications, sizes, colors and consistency, is difficult to control from the past experience.

The quality target of this project is the Great Wall Cup project. At present, the control of structural size and appearance perception has reached the pre-control goal. Therefore, the quality of decoration engineering must overcome the construction difficulty brought by the material itself, achieve the goal of "fine and coarse granulation", and ensure that the perception and measurement achieve the quality pre-control goal.

In addition, the construction period of decoration project is tight, so it is necessary to arrange subcontractors and specialties reasonably to ensure the progress.

4.3.2 Formwork production: Before the structural acceptance, choose the on-site fence or office exterior wall for the outer edge decoration formwork construction, and the construction focuses on the uniformity and three-dimensional effect of the coating, so as to reach the quality standard of pre-control. Select typical indoor decoration rooms for model building, including: fine stone concrete floor model, kitchen, bathroom wall model, floor tile model, and model room on the second floor. Large-scale construction should be carried out after the self-inspection, supervision and acceptance by the owner of each major of the company.

4.3.3 Drawing review of hydropower and civil engineering: In order to avoid engineering rework caused by non-intersection between specialties, before renovation, all the equipment, holes and devices in the same position are drawn on a drawing by computer, which is presided over by the chief engineer of the company and attended by professionals of the company and the project. If there is no overlap, it will be solved in advance before renovation.

4.3.4 The foreman shall prepare the operable construction technical disclosure in combination with this construction scheme to guide the workers in construction.

4.3.5 Prepare suitable working faces for workers' operation, with intersecting working faces. The technical director of the project department will coordinate the task sequence, and uniformly arrange the cleaning and handover of the construction passage, means of transportation, transportation sequence and working face. This project has a tight construction period and high quality requirements, and there shall be no uncooperative and fragmented work of each type. Once it happens, the parties concerned will be held accountable, hell to pay.

5. Construction method Before the decoration project construction, each floor and room should provide a unified elevation line and cross center line for civil decoration and professional facilities installation. Therefore, at the beginning of the decoration project, the +0.5m elevation line consistent with the structural stage should be played on the wall of each room, and the cross centerline should be played on the floor, ceiling and wall, and the cross centerline should be consistent.

Before the formal start of decoration construction, skilled workers must be selected to carry out model room construction, and large-scale decoration construction can only be carried out after on-site inspection and approval by the owner, supervisor and design institute.

5. 1 Fine stone concrete floor According to the design requirements, all floors except the kitchen and bathroom are made of fine stone concrete;

Technological process: find the horizontal base with elevation elastic surface layer, sprinkle water to wet plastering cake, brush plain cement slurry, pour fine stone concrete plastering layer, and calender and maintain;

According to the +50cm horizontal line on the wall, measure the horizontal line on the ground and bounce it on the surrounding wall, which is consistent with the elevation of the corridor and other rooms outside the room; Clean up the dust first, then shovel off the pulp skin stuck on the base, brush off the oil stain with alkaline water, and finally rinse the base with clean water;

Sprinkle water on the grass-roots surface the day before operation; Brush bonding layer, plaster cake, screed, and pour fine stone concrete: spread the mixed fine stone concrete on the ground bonding layer, scrape it flat along the standard reinforcement with a 2m scraper, and then vibrate it with a flat vibrator until the surface oozes water. Dry-mix the mixture of 1: 1 (cement: sand) and smear it evenly with a 2m-long scraper.

Calendering of the surface layer: when the surface layer absorbs water, rub it flat with a wooden trowel, and mix the dry cement-mud-sand mixture with the fine stone concrete slurry to achieve close combination; First calendering: lightly press with an iron trowel until pulp is produced; Secondary calendering: when there are footprints on the ground after the initial setting of the surface mortar, but they do not sink when going up, use an iron trowel for secondary calendering, and fill up the pits and sand holes, taking care not to leak pressure; Third Calendering: When the surface mortar is finally set, that is, there is a little footprint when people step on it, and there is no scratch, an iron trowel is used for the third calendering. This time, you should press hard and wipe all the lines clean.

Maintenance: water for maintenance after 24 hours, not less than twice a day, and maintenance for not less than 7 days.

5.2 Ceiling Project The ceiling of this project is mainly set in the underground passage, and the installation clearance of the walkway is an integral multiple of the size of the ceiling block. Therefore, when arranging slabs along the length of underground passage, the control line should be set on the center line of each underground passage, and the center line determined by the size of the side plate of underground passage should be keel or middle plate.

During the construction of suspended ceiling, embedded parts should be set on the bottom of cast-in-place concrete floor according to the design requirements. Before the installation of welded keel suspenders, elastic lines shall be segmented according to the structural requirements to determine the installation position of pipes in the ceiling, so as to avoid damaging the keel by positioning the keel according to the keel after installation.

Installation and pressure test of ventilation, water and electricity pipelines and fire pipelines in the ceiling are completed; The panel can only be installed after the lamp trough is installed.

5.3 Shot peening on the wall and putty on the interior wall roof: the exterior wall coating of this project is light pink, and the waistline is white. Clean the wall, remove the peeling and looseness of the wall, fill it with cement mortar, shovel the residual ash, and then sweep the wall.

Wall repair: leveling the concave-convex and dust gaps on the wall with gypsum, drying, grinding off the protruding parts with sandpaper, and sweeping away the floating dust.

Spraying: the wall surface shall be sprayed after passing the inspection, and the first layer shall be sprayed and accepted by relevant personnel before the surface construction can be carried out.

Paint for the first time: the order of painting is up first and then down. The paint should be mixed evenly before use and diluted with water to prevent the paint brush from being blocked. After drying, paint for the second and third times.

Putty for interior wall and roof: the interior wall and roof of this project are waterproof putty.

Cleaning the wall and top surface: clean the peeling and looseness of the wall and top surface, fill it with cement mortar, shovel the residual ash, and then sweep the wall surface.

Repair of wall surface: level the unevenness and potholes on the wall surface with gypsum, dry them, grind off the protruding parts with sandpaper, and sweep away the floating dust.

Blow putty: blow putty completely for the first time, and be careful not to miss it. After washing the dry bath, use sandpaper to smooth the putty residue and spots on the wall, and then clean the wall. The second time is the same as the first time. After thoroughly drying, smooth it with 1# sandpaper and clean it up. The third putty is very important, and it must be smooth and clean after scraping.

5.4 The selection of glazed tiles in ceramic tile kitchen and bathroom should be controlled; Because ceramic tiles are low-grade materials, specifications, sizes and colors are not easy to be consistent, so we should make great efforts to select bricks before construction: first, make a good mold and divide the specifications and sizes on the mold. Those exceeding 1 mm belong to one category, and those not exceeding 1mm belong to another category; At the same time, pay attention to the color difference, put tiles of different colors in classification code, and lay tiles of the same color scale in the same room. Choosing bricks is an important content to achieve a good impression, and this work must be done as an important process.

Base treatment: before pasting, clean the base of the wall, check the flatness of the wall, and scrape off the protruding wall or concrete.

Priming: firstly, water the wall and wet it, then paint 1: 3 cement mortar layer by layer, with a thickness of about 12mm, and hang it straight and scrape it off. Primer should be brushed off or scraped off. Water conservation after 24h.

Brick arrangement and elastic line: when the base is 60% to 70% dry, brick arrangement can be carried out according to the drawing requirements.

Start from the yang angle and proceed from top to bottom, and try to keep the brick in the yin angle. When there is a pool, be sure to stick it on both sides with the pool as the center. Play the horizontal and vertical control lines on the bottom mortar, with the vertical line spacing of about 1m, and play the horizontal line with 5- 10 pieces according to the specifications of ceramic tiles.

Sticking standard point: Stick waste bricks on the bottom mortar, and when sticking, the edges and corners of the bricks will be inclined, and the edges and corners will be used as the standard of the surface smoothness of the embedded bricks. When pasting, draw a vertical line on the corner of the ash cake brick, and then tie the movable horizontal line to the vertical line to control the surface smoothness of the brick.

Bottom ruler: according to the calculated elevation of the bottom brick opening, the ruler board is padded as the standard of the first brick opening. The footing must be placed horizontally, stably and smoothly, and the spacing between the footing pads should be within 400 mm.

Bricks used for inlay and pasting should be selected in advance, soaked in clear water for 2 hours, removed from the surface to dry, and pasted with mixed mortar from bottom to top. A row of bricks should be stuck firmly at the door or at the external corner and on the long wall every 2m, as the standard of vertical, flat and brick layer of the wall. Then stick the line to both sides according to this standard.

After pasting, self-check whether there is hollowness, unevenness and straightness, and rework and repair in time when problems are found. Then rinse the tiles with clean water and wipe them with cotton yarn. Dip thick white cement with a long brush at least to the joint, and then wipe the plain slurry of the joint evenly with cotton yarn.

Cross plastic cards are used to control the joints between tiles.

Cutting measures for plumbing pipe support: determine the position of pipe support in advance before pasting, and reserve two tiles, up and down or left and right, without pasting. According to the construction drawing, make the vertical and horizontal projection lines of the pipeline on the wall, so that the projection lines are on the vertical or horizontal lines of the tiles, measure the distance from the bracket to the edge of the tiles, and cut the tiles.

5.5 Specification of exterior wall imitation mushroom stone decoration material: 600× 300× 5,400×100× 5.5, gap15 ~18 mm;

Base treatment: when the base flatness exceeds 15mm, it shall be leveled with cement mortar; Positioning and setting-out, fix the bracket with expansion bolts at a distance of 600mm, mix Guangdong 923 glue with ordinary portland cement and sand at a ratio of 0.5: 1: 1 to form mixed mortar, spread polymer mortar with a width of 15mm around the insulation board, put the insulation board on the bracket, stick it on the wall, and tap the insulation board with a rubber hammer to find out the flatness. Finally, use 1: 1 cement mortar to wipe the seam, and make it concave by 2mm, and paint the surface with blue paint.

5.6 Process flow of door and window engineering: find out the rules of door and window openings, handle embedded parts and connecting iron pieces, unpack doors and windows, check in place and temporarily fix door and window sashes, seal and caulk, clean and install hardware fittings, and install door and window gauze sashes sealing strips.
