5, put tube packing line tube conductor cross-sectional area of not more than pipe inside diameter size of 40%, the tube of a connector and twisted.
6, power supply lines and heating, hot water, gas tube parallel spacing should > > 300mm, intersection spacing 100mm.
7, the power cord of the fire, zero, and three line should use the two merged into one line, one-color line, the prohibition of the use of flowers line do FireWire. When the power cord to the branch, you should use junction.
8, PVC pipe as flame retardant pipes, their number is a thread, that is 20 mm pvc pipe can be cut into 4
Power cord: 16mm of pvc pipe can be cut into 3 power cord, multiple effects in the membership of the power line, pvc pipe requires a solid, seamless connections exist. Housing top layout of PVC pipe, pvc pipe and the wall top fixed: PVC pipe into line, and lines connecting with the latch.
9, the strength of the wire is not in the same pvc tube placement, reduce power interference between them.
In particular, communication cable, signal cable wiring style, orientation, dark distance short tube level should not be more than laying, otherwise it should be mounted 30m crossing the cartridge. And power line, the spacing of the metal pipes should not be less than 500 mm, and metal pipes, hot water pipe with parallel spacing of not less than 1000mm. IV. waterproofing: 1, Interior waterproofing works according to the material divides into waterproof membrane and polyurethane waterproof coating.
2. polyurethane waterproof coating determines a good manufacturer, brand, quality products.
3. when making waterproof first and do one layer wall or tile floors, cement mortar or water leakage for calendering leveling, and down to the nozzle to 2% of the slopes, in the well after polyurethane waterproof coating full coloured 2-3 times.
4, in brushing, since returning to the wall screed height 300mm, firewall body and shower area should return to 1800mm high to ensure that no leakage requirements.
5. construction change water pipeline wall slotted after application of waterproof coating brushing twice do waterproofing treatment, in wall tile before waterproofing floor protection processing, used to do the water does not drain dry waterproofing sprinkled on the level or use packaging cartons on it.
6, wall after the surface paving, using CB water-repellent small brush for each brick stitch brushing, four edges of glass plastic playing seal, which can better prevent customers use water leakage.
7. do a waterproof layer, based on the material conditions for construction of its dry after waterproof closed water testing, water is the water away from the highest point on the water time 200m deserves at least 24 hours. 5. wall surface paving project 1, this works mainly for paving tiles.
2, according to the specific project can be divided into primary processing, materials, auxiliary materials, construction methods, finally ending processing.
3, primary processing of construction project now can be divided into gross surface of grass-roots, after the demolition of smooth grass, grass-roots level 3, the gross surface of grass-roots do not need to do additional processing, as long as the paving of grass-roots with water before immersing a smooth base construction before doing the original surface, chiseling processing can tile soaked. After the removal of base because of its removal from the original structure layer when you should be as clean, then soaked with water before construction.
4, building materials, first select the tile, the material to be used should be consistent in color specifications, corner of lesions, the surface is smoothIntact in order to meet construction requirements.
5, auxiliary materials including cement, sand, goufeng material, cement use current national publication standard 325 # cement (# 425), the sand is filtered water sand, cement mortar ratio should be 1: 2.5 ratio ratio of construction.
6, construction method: paving bricks will be clean before dropping into the water-soaked 2 hours until the surface is dry before use, selected good bricks should do a walk-through for bricks to control even, at the same height or width of the wall, should not have a line of non-whole brick, not from the bricks should be placed in a secondary site and Yam corners, each piece in the paste should be consistent with a flat, the slit. For the brick veneer finish, its empty drum brick should replace knocked down.
7, in large slabs paving indoor, first soak the ground, on the wall the horizontal line, horizontal line will cross for conducting construction.
8, the last step is to finish the tile installation, use the white cement or professional goufeng will brick stitch Groove. 6. wood production engineering (1) conform to the drawings, the budgetary requirements.
2. ceiling (gypsum board) works in the construction of the first wood joist using plus four wooden side, according to the national standard of moisture content of wood made up of 10-12% control the construction.
3, according to the suspended ceiling design elevation in the surrounding wall elastic cord, its level tolerances ± 5mm, edge joist is fixed in the surrounding wall, flat-topped middle section should arch, secondary joist width should be not less than 40mm, keel after installation should check for solid and reliable, regular gypsum board of secondary joist spacing should not be greater than 600mm.
4. when installing gypsum board, use of standard 9mm thick gypsum board, use of nailed method, screws and plates edge distance not less than the distance between the screws 15mm to 150-170mm uniform layout and vertical with the Board, nail head embedded depth of gypsum board to 0.5-1mm as a standard, dingmao brush antirust paint, PuTTY, install double effacement of gypsum board, surface plates and base plate joints should be staggered, no seams in the same keel, plasterboard and keel fixed, from a Board in the middle to the edges shall be fixed, at the same job multiple points.
5, at the made wood production (door set, heating enclosures, cabinets, wooden top line), the first should be consistent with the requirements of the design estimates, wall fixtures should be fixed with wooden fixed method, use the door Cabinet carpentry Board backing leveling, overlying density Board, and then paste using LaTeX, Panel nailed, nail spacing 8-12cm, nail length 20-30cm, dingmao enters Pan 0.5-1mm, nail ophthalmic complement flat, greasy child in construction should keep door Cabinet and door set of vertical and smooth.
6. door: door thickness is generally around the middle to 4cm wood panels, double-sided open slot with latex paint adhesive deformation and that the Panel is density Board with decorative plywood, plastic synthesis repression after 3 days, you can use to do the next step, according to the company's wood technology, modeling with glass doors, trim line-side when the plate glass and decorative panel edges have a straight slot 3mm-5mm.
7, Cabinet: Cabinet of the dimensions of the skeleton under drawings, programme production, skeleton using woodworking Board, medium density Board, dual panel (thickness for control over the 12cm) internal white LaTeX plaster decorative panels, plywood bonded main, plate orifice uses scuttle lines handle door use good fortune people MDF-sided open deformation Groove, White Emulsion adhesive Panel gag.
8, fine wood production requirements for construction materials, workmanship, some dedicated lines should consider the quality of its construction back if there is a problem. VII. paperhanging construction: 1, level of immersion paper in a few minutes, in the back of the brush grass roots or wallpaper adhesives, the first piece of wallpaper and redbud will be mounted paperhanging the surface dirt, dust clean, crystalline bloom parts use P% acetic acid and, without anesthesia, sand and cracks, Yin and Yang Kok straight.
2. paperhanging the former should use white LaTeX painted base, then call using PuTTY, leveling polished flat base, with a varnish coating as the adhesive to paperhanging.
3. Paste the wall before playing the vertical alignment for paperhanging, paperhanging, time pressure bubble extra bonding agent and air out, catch a plane.
4, seams horizontal even vertical, patterns, patterns are on the corner of the yin, Yang Kok lap Office cannot seams. 8. paint production finishing works: 1, primary processing: first base blew up PuTTY, but on the application of the wall cracks do good cloth brush adhesive PuTTY real, then scrape, sand paper mill flat polishing, surfaces must be smooth, straight line angle. (Wall base)
2. gypsum board base, should be asked on the Board joints, nail hole edge line processing, full scraping PuTTY, sandpaper backlit flat grinding.
3, wooden base surfaces must be smooth, clean, color, no cracks, broken.
4. in roll painting wall top paint, mostly with the brush, wool roller, for construction, using the brush should use good quality wool brush construction, wool roller when used in a large area is very convenient, but in the upper and lower mouth, vaginal application wool brush corners for construction.
5, facings brush varnish: first of all on the nail eye colored oily child fill xiuping, brush varnish is a paint brush, it will be for local colour retouching on polishing processing until the tone after reunification, then do a final topcoat, sandpaper polishing with high density.
6. Brush Matt (polyurethane): first full brush boiled oils, and other film stem with rich child will screw eyes, cracks, broken and scraped manxiu flat, smooth, dry grinding and brushing Matt, after each pass sandpaper to guarantee you the film surface is smooth, and smooth.
7, for the unique climate and Xinjiang construction differ, the walls have the crystalline bloom phenomenon, you should use 3% of oxalic acid to clean, washed with water after clean or you can base with brush again, wall closed primer, dry after scraping PuTTY, polished flat, smooth surface coating after brushing.
8, for wall PuTTY scraping, sanding finish when it is best to use a special tool, not to hand Polish, otherwise it will Polish the rough, polished is well-distributed don't wear that.
