The interior decoration project starts from the signing of the contract. The project is divided into sub-items such as demolition and renovation, water circuit renovation, wall and floor paving, wood production, paint production, installation facilities, and indoor cleaning. According to each of the different requirements, a Basic construction standards: Third, the layout of the circuit layout: Fourth, waterproof engineering: >>>Link: Graphical process of tile dry shop Six, wood production engineering Construction Acceptance Paint Cement Paint Glass Plaster Ceiling Ceiling Glass Brick Cabinet Cabinet Door Glass Cabinet Technology Glass Wall Cabinet Glass Door Glass Door Door Tile Price Tile Tile Size
First, demolition and reconstruction:
1. This project mainly displays the dismantlement of the original civil-built wall due to the requirements of the design scheme to meet the functional requirements. In the demolition, the main wall is non-bearing wall, simple partition wall, hollow wall and so on.
2. Additional treatment for some of the original civil installations is as follows.
3. When doing this project, first of all, protect some facilities such as water, electricity, roads, pipelines, and waterproof layers to avoid damage, and use light steel keels, cement pressure plates, and stencils when securing the tubes. Hanging pulp, steel mesh should be used mesh spacing 10-15mm, steel wire diameter 2mm steel mesh, light steel keel using the national standard, hanging pulp should reach 3cm thick before they can be tiled.
Second, the waterway transformation:
1. First of all, the transformation of the water pipeline (Sheung Shui) should use the PP-R pipe with low price but good construction quality on the market.
2, PP-R pipe is non-toxic, clean and sanitary, with high compressive strength and good heat insulation.
3, The water supply pipeline should adopt the water test, and the general civil {6-story residential building} construction pipeline pressure carries 2kg, and the leakage should be checked.
4. Pipes should be laid horizontally and vertically. Pipes should be set at 10cm at the end of the pipe. The pipes must be secure and cannot be loosened.
5, Pipes and pipes, valve connections should be tight, hot-melt pipe connection.
6, all kinds of valve installation location should meet the design requirements and functional requirements.
7. The installation positions of valves and faucets should be upright, flexible and convenient to use, the water flowing unimpeded, and the water meter running normally. Water meters, valves are in a relatively concealed position and inspection devices should be left.
8, When using PP-r pipe thermal fusion, the temperature of the thermal container should be maintained at 260 degrees Celsius in order to see no water seepage.
9, the transformation of the use of special PVC glue, generally do not stay away from the original drain. If it is necessary to adjust the position from the changed position to the original position, it will facilitate the smooth flow of water into the main pipeline.
1. The laid wire must be laid with PVC sleeves, and the quality of wires and electrical appliances must comply with current national standards.
2. When the flat top is suspended, the electrical equipment shall be piped. The piping shall not be fixed on the flat top of the rib or keel.
3, The switch and socket must have a cassette, the surface of the cassette is flat, the appearance is intact, and the installation is firm.
4, The socket is generally 30cm away from the ground and should not be lower than 20cm. The switch is generally 130cm away from the floor and installation should be considered for ease of use.
5, The sum of the cross-sectional area of ​​the conductors in the pipe threading line shall not exceed 40% of the area of ​​the inner diameter of the pipe. There is joint and twisting in the pipe.
6. The parallel distance between the power line and heating, hot water, and gas pipes should be >300mm and the crossover distance should be >100mm.
7, the power line of the fire, zero, and three lines should be used with two colored lines, a two-color line, the prohibition of the use of flower lines to do FireWire. When the power cord needs to be branched, use a distribution box.
8, pvc pipe as a flame-retardant pipe, the number of threading is certain, that is, 20mm pvc pipe can penetrate 4
Root power line: 16mm pvc pipe can penetrate into three power lines, more penetration will affect the normal operation of the power line, pvc pipe connection requires a solid, seamless existence. When the pvc pipe is arranged on the top of the house, the pvc pipe and the top of the wall should be fixed: When the pvc pipe enters the line, it should be connected with the cable box with a latch.
9, strong and weak wires can not be arranged in the same pvc pipe to reduce the power interference between them. In particular, communication lines and signal lines have smooth lines and have short alignment distances. The laying of dark pipes should not be more than 30m horizontally. Otherwise, over-the-counter boxes should be installed. The distance between the power line and the metal water supply pipe should not be less than 500mm, and the parallel distance between the metal drain pipe and the hot water pipe should not be less than 1000mm.
1, interior decoration waterproof engineering can be divided into two kinds according to the material of waterproof membrane and polyurethane waterproof coating.
2, Polyurethane waterproof coating to determine a good manufacturer, good brand, good quality products.
3. When doing waterproofing, first make a layer or even layer on the floor or wall, use cement mortar or water to do the pressure leveling treatment, and give a 2% slope to the water outlet, and then use the polyamine after doing a good job. The grease waterproof coating is applied 2-3 times.
4. When brushing, the self-leveling layer returns to the wall with a height of 300mm. There is a requirement for a firewall body and the shower area should be returned to a height of 1800mm to ensure that no water leakage is required.
5. Waterproof coating shall be applied after the wall of the water pipeline is changed during construction. Waterproof treatment shall be applied to the waterproof wall. Before the wall tile is tiled, the waterproof surface shall be protected. The water shall not be spilled on the waterproof layer or used for packaging. Carton is placed on it.
6. After the wall surface is tiled, use the CB waterproof agent to brush each brick seam with a small brush, and seal the edges with glass glue. This will better prevent customers from seepage when using water.
7, after the waterproof layer is made, according to the construction conditions of the material, etc., after it is dry, make a waterproof water-blocking test. When the water is released, the water should be 200m away from the highest point and the water discharge time should be at least 24 hours.
Fifth, the wall ground paving project
1. This project is mainly for paving tiles.
2. According to this project, it can be divided into basic processing, material selection, auxiliary materials, construction methods, and final finishing.
3. Grassroots treatment The basic construction projects can be divided into three types: rough surface base, smooth surface base layer, and base layer after demolition. The rough surface base layer does not need to be treated in other ways. So long as the base layer is soaked with water before laying, the smooth base layer Before the construction, the original surface must be treated with a haircut, and the bricks can be tiled only after the water is immersed. After the dismantling, the original structure layer left behind by the dismantling shall be cleaned as far as possible, and the submerged water can be used for construction.
4. The first choice of building materials is the choice of tiles. The materials to be used should have the same specifications, no damage to the corners, and good surface finishes before they meet the construction requirements.
5. Excipients include cement, sand, caulking agent and other materials. For cement application, the current national standard 325# cement (425#) is used. Sand is the selected washed sand, and the proportion of cement mortar should be proportional to 1:2.5. .
6. Construction method: Put the clean bricks into the water for more than 2 hours before paving. Wait until the surface is dry before use. The selected bricks should be pre-arranged so that the brick seams can be controlled evenly and on the same wall. In the horizontal and vertical arrangement, there should not be a row of non-complete bricks. The non-complete bricks should be placed in the secondary area and in the female corners. After attaching each block, the four sides should be flat and the gap should be the same. For finished bricks, empty drums should be knocked down and replaced.
7. When paving indoor floor tiles, you should first soak the ground, put the horizontal line on the wall, and set the cross horizontal line before you can carry out the construction.
8. The last step is to use a white cement or professional grout to ditch the bricks after the tiles are plastered.
1, in line with drawings, budget requirements.
2. In the construction of ceiling (gypsum board) project, the wood keel is first used with the addition of Simufang, and the moisture content of the wood formula is controlled according to the national standard of 10-12%.
3. According to the design elevation of the suspended ceiling, the horizontal line allows the deviation of ±5mm. The side keel is fixed on the surrounding wall. The middle part of the flat top should be arched. The width of the secondary keel should not be less than 40mm after the installation of the keel. Should be checked whether it is solid and reliable, fixed gypsum board sub-keel spacing should not exceed 600mm.
4. When installing gypsum board, use standard 9mm thick gypsum board, use nail fixing method, the distance between screw and board edge is not less than 15mm, screw spacing is 150-170mm evenly arranged, and is perpendicular to the board surface, nail head is embedded in the depth of gypsum board To 0.5-1mm as the standard, nail cap brush anti-rust paint, and putty with the putty, when installing double gypsum board, the joint between the surface layer board and the base board should be staggered, shall not be jointed in the same keel, gypsum board and keel fixed , should be fixed from the middle of a board to the four sides, not more at the same time.
5. When doing wood production (door covers, heating covers, cabinets, wooden top lines), the requirements of the design budget shall be met first. When the walls are fixed, the wooden lock shall be used to fix the door cabinets, and the wood boards shall be used for bottoming and leveling. Overlying medium density board, and then using latex adhesive panel, when the panel is nailed, the nail distance is 8-12cm, the nail length is 20-30cm, the nail cap is 0.5-1mm into the board surface, and the nail hole is filled with oily putty, during construction. The vertical and level of the door cabinet and door pocket should be maintained.
6, door production: the thickness of the door is generally about 4cm, in the middle for the wood board, double-sided deformation tank with latex paint stick, the panel for the MDF board veneer plywood, glue synthesis suppressed after 3 days can be used to do The next step, according to the company's wooden process, with a glass door, and then close the glass plate edge and the edge of the panel there is a 3mm-5mm straight slot.
7, cabinet production: cabinet skeleton according to the size of the drawings, program production, skeleton use wood board, MDF, double panel (thickness is controlled in more than 12cm) interior with white latex paste decorative panel, outside the main decorative panel, The plate mouth is used to close the door and the cabinet door is opened. The Futian MDF is used to double-side open the deformed groove and the white latex adhesive panel is pressed.
8, fine wood production requires construction materials, fine workmanship, some special lines should consider whether the quality of its construction problems.
Seventh, paste project:
1. Put the paper in the horizontal soak for a few minutes. Brush the adhesive on the back of the base or wallpaper. The dirt and dust on the surface of the base should be cleaned before the first wallpaper and wall paper are stenciled. There must be no spots, sand and cracks, and the yin and yang angles are straight.
2. Before applying the paste, white base coat should be used to paint the base layer, and then putty should be used for the base layer. After the leveling and polishing is finished, use varnish as the primer to paste.
3. Before the batter is pasted, first use the vertical line as the squeegee alignment line. When the paste is smashed, press the air bubbles to expel the excess adhesive and air and rush out.
4. The seams are horizontal and vertical, and the patterns and patterns are all matched. The female corners are overlapped and the corners cannot be seamed.
Eight, paint production and finishing works:
1. Grassroots treatment: First, the grass-roots scrape the putty, but the cracks on the walls of the application of good cloth adhesive glue, and then scraping putty, sandpaper polished polished, the surface should be smooth, straight line angle. (wall base)
2. The gypsum board base layer shall be treated as required, and the board shall be sewn and nailed on the side of the eye.
3, wooden base surface should be smooth, clean, consistent color, no cracks on the surface, incomplete phenomenon.
4, when the roller coating the top paint, mostly with a brush, hair rollers, construction, the use of a brush should be selected good quality wool brush construction, hair rollers used in a large area is very convenient, but in the upper and lower mouth, Yin Apply a wool brush to the corner for construction.
5, veneer brush varnish: First of all, the nail eye with colored grout to fill the leveling, brush varnish is a brush every paint, for local repair color to the polishing process, until the color is uniform, then do the finish, and finally with High density sandpaper polish.
6, brush and reconcile paint (polyurethane): first full of brush oil again, and other paint film dry with an oil putty will nail eyes, cracks, incomplete scraping at the Department of trim, dry and smooth after grinding, and then brush to reconcile the paint, after each pass Grinding with sandpaper to ensure that the surface of the paint film is smooth and smooth.
7, for Xinjiang's unique climate and construction is not the same, the wall has the phenomenon of ubiquitous, it should first use 3% oxalic acid cleaning, after the clean water can be flushed or full brush on the grass again, the wall closed bottom Lacquer, can be putty after drying, polished smooth, smooth after coating the surface coating.
8, after the wall scraping putty, it is best to use a special tool when grinding, can not be hand-polished, otherwise it will be polished uneven, do not grind the bottom evenly when grinding hard.
