box opening should be tidy (2).doc

1, the surface of the base must be removed, and the day before plaster water should be fully wet. 2, it is forbidden to use lime mortar and mixed mortar base paint. 3, with the height of the wall covering paper reinforced ash should be controlled, dont put on the part of the skirting board, if sometimes, should be carefully cleaned after plastering cement mortar skirting board surface again. 4, strictly control the size of water to cement ratio of cement mortar, dont too thin. Consistency should be controlled at about 3.5 mm, plaster layer thickness should be layered manipulation. 3: common fault ground down the water with a floor drain The reason: 1, outside the balcony, corridor, toilet, the toilet on the ground, generally 20 to 50 mm lower than the indoor ground, but sometimes just as flat design, construction and not in accordance with the relevant provisions of the construction, causing the ground water. 2, ground elevation copy ping tan line is not accurate, not in accordance with the stipulations of the surface of a floor drain in the construction requirements of the water slope screed, leveling. 3, high floor drain installation, forming around the water. Solution: 1, must control the balcony, corridor, bathroom, toilet, the toilet on the ground level, should be 20 50 mm lower than the indoor ground. 2, the construction should first ensure that the ground elevation, the accuracy of the water slope at the local level. Do before, should be based on the elevation of floor drain, floor drain direction do radioactive screed, looking for a good grade, leveling with your ruler. 3, installation of floor drain with civil work closely and adjust the level should be paid attention to. Floor drain should be relatively low ground 5 10 mm, floor drain plate shape. Common fault 4: floors, empty drum The reason: Cushion layer surface cleaning not clean, water too dry or wet enough, cement combined with uneven layer coating or coating time is too long, dry and hard, causing surface and cart bonding is not strong, resulting in an empty drum. Solution: Cement mortar, before laying should carefully clean up the garbage, dust and pollutants on the surface of the grass-roots, and rinse: surface should be rough at the grassroots level is too smooth to cut hair for processing; Water to fully wet; At the grass-roots level surface coating slurry, water cement ratio should be controlled between 0.4 0.5, and do it with the brush with the laying of cement mortar. Plasterboard condole supports 1, since construction should cooperate with other units to draw comprehensive top surface active, as the top of the lamp hole, tuyere, manhole and so on the basis of a pay-off. The deputy keel should avoid all parts mentioned above. In the installation of equipment at the bottom of the lighting lamps and lanterns and the speaker should pay attention to the size of the embedded depth, such as adjustment in advance. Before the installation of the keel, should according to the design requirements for the room clear height, the mouth of the cave elevation and the ceiling piping, equipment and support the elevation of the handover inspection. Prevent cross construction installation lag process involved. 2, top of gypsum board and beam body and walls of closed head cant flush, is to be found as early as possible with previous alignment and make design changes. 3, accessories and the main keel next seamless, master to tighten. Screw expansion head to control the quality of the good. Derrick is apart from the main keel end distance shall not be greater than 300 mm, when greater than 300 mm, should increase the boom. When the boom length is greater than 1.5 mm, should set up the support. When derrick encounter with equipment, should be adjusted and adding derrick. Heavy lamps, electric fans and other heavy equipment installed in the ceiling keel of engineering are strictly prohibited. 4, ceiling gypsum board face various aisles or straight line length is more than 15 meters large condole top corner should be reserved expansion joints. Expansion joints in the left and right side should be added during the construction of two independent of all the main keel, keel must be disconnected. Pay attention to the condole top of not less than 1/200 span arch camber. Office, guest room and other small studio should press room short span of 1 to 3 bulging. 5, expansion joints can be used glue, embedded in glass, 50 * 70 concave joint treatment. Depending on the requirements of the project, using the expansion joint processing of sealant should be hidden, can be put in modelling groove Angle of Yin. 6, condole top border keel with 50 deputy keel. Main keel should use 60 series and indicate the derrick specifications galvanized wire rod steel hanger and length. 7, gypsum board, plate seam must be a V shape mouth, upper plane in advance before the good; Plates shall be installed under the free state and fixed when around from the middle plate to plate fixation. Tapping the self-contained silk dont destroy the paper, under 1 mm 2 mm, tapping the self-contained silk from the appropriate edge distance of 15 mm, damp environment can use waterproof gypsum board and galvanized tapping screw. Plasterboard is prohibited to use needle nail fixation. 8, end face sealing plate is best double 9.5 1.2 thick thick or single, gypsum board top corner joint have to stagger the 30 centimeters, corner cutting with L word, can prevent the cracking. But must pay attention to not open wound plasterboard, otherwise dark crack hidden dangers exist. Construction should be controlled well in the wastage of the gypsum board should be used in a timely manner. (cutting the rest of the gypsum board should be piled up in the designated areas) installing a double plasterboard, surface plate and base plate seam should be staggered, and shall not be in the same seam on the keel. 9, condole top fold or lamp chamfer flanging in the hidden should indicate as the wooden keel joinery board at the grass-roots level, surface gypsum board. 10, take cover without the write size of wooden keel, to introduce more than top part of the joinery board should state into highly. As a fold or flanging grassroots joinery board must be L type can be used. L type bottom connected to the deputy keel, to guarantee the straightness. 11, the common vault can moisten the plasterboard, pressing sealing plate after finalize the design. Special requirements of the use of custom strengthen profiled fiber plasterboard. Light steel keel gypsum board partition 1, and wall partition keel, cylinder head butt. Can be recessed or protruding, pay-off at the scene can be adjusted in a timely manner to make design. 2, partition keel to assure sound insulation, prevent cracks, sealing plate is best can use double double 9.5 thick plasterboard, fill in sound insulation cotton. Keel gypsum board and keel on either side of the side of the double plate seam should be staggered, not on the same root keel joint. 3, the doorway, humanly scaled the plasterboard boards around the seam must be on the center line, in order to prevent cracks in the future. 4, partition keel next to stone or wood skirting board, when the seal plate must be set aside the space. It is best to double stick stone base steel net. Wood kick 9 mm plate note anticorrosive, fire prevention at the grass-roots level. 5, gypsum board, plate seam must be a V shape mouth (before shaved) in advance. When fixed plate should be the middle to the plate fixation. 6, tapping the self-contained silk dont destroy the paper, under 1 mm 2 mm, tapping the self-contained silk from the appropriate edge distance of 15 mm, damp environment can use waterproof gypsum board and galvanized tapping screw. 7, plasterboard is prohibited to use needle nail fixation. Sealing plate transverse joint place not on the along the ground, along the roof keel, should add lateral brace keel fixed. Installing a through series of keel, partition to install a less than 3 m, 3 5 m partition to install two. Emulsioni paint, wallpaper, 1, new paint the walls and old metope place, should be paste mesh cloth before construction. Paint the walls and other wet homework should be completed in the early days, so that it is fully dry. New building concrete or plaster base should besmear before finishing coating alkali resistant sealer. Old metope should clean up loose old decoration before finishing coating layer, and the coating interfacial agent. 2, unfavorable use cellulose, prevent FanJian, long hair. Whiskering at the grass-roots level should be in the 3% oxalic acid solution to clean, then wash clean with clear water or full brush again on grassroots alkali resistant primer, wait for after its are blow be bored with child, besmear again brush surface coatings. 3, emulsioni paint of the last two times must be spraying, spraying pay attention to product protection). After spraying if metope damaged to repair are still use the spray, cant use wool brush or roller to repair construction. 4, latex paint and other surface decorative surface cross contamination. (especially pay attention to some of the top surface, lamps and lanterns, tuyere, spray, windowsill next mouth, the metope of the line that play a base, the switch panel and other parts of the check) 5, at the top of the wall Angle of Yin and Yang to straight, should first play line, after a batch of ash. (by the specialist is responsible for checking) 6, the wallpaper before use to try to stick to prevent appear off color, fade, joint significantly. 7, the wallpaper order must have the plan to prevent partial stock produce off color phenomenon. 8 and the metope of the back cover to be hidden, measures should be twice concealment. Plasterboard surfaces with seam, should do two layers of concealment. 9, metope should use picture by pasting, first, horizontal after vertical bedding face after detail first, ensure vertical before flowers flat-fell seam, vertical plane is, after the first short wall after long metope first, low water level is high before. Yang Angle place should Angle shall not have juncture, Yin Angle seam should be suitable light overlap. 10, should pay attention to different material wallpaper flooding. Composite wallpaper not flooded, coating adhesive on the back of the wallpaper, should be taken before pasting place for a few minutes. Textile fiber wallpaper should not be soaked in water, appropriate use wet cloth clean before pasting on the back. Polyvinyl chloride (PVC) plastic wallpaper should look to wallpaper wetting with water for several minutes before, metope should be at the grass-roots level surface coating adhesive when pasting. Metal wallpaper before flooding should be 1 2 min, air-dried min 5 8 on the back of the brush after special wallpaper powder glue. 12, should choose wallpaper to use glue correctly, generally has the following technical requirements: pasted with glue should be water-soluble, construction conditions better tools to clean and convenient. Pasted with glue should have certain moisture resistance, so that at the grassroots level have a certain moisture content can still be used, to shorten the construction period. Pasted with glue should have certain mouldproof. Have fire prevention, waterproof performance wallpaper glue, should have waterproof, fire prevention performance accordingly. Wood veneer, soft package engineering Wood veneer Wood as the class in the construction site should be considered relatively independent processing place, easy to control the wastage of the material and site management. Surface or width and height of the door leaf should consider to act the role of the size of the panel, should reduce wear and tear. Surface or wood veneer door leaf to consider the unity of the wood surface pattern. The tongue-and-groove flat-fell seam must leave, if any, shall be not close. The door or wood surface height more than 2.4 meters, should handle seam. Processing board to pay attention to the unity of the pattern (the cross spell ornamental design decorative panels, panel, twill, scale plate, etc.). Set processing products should be chosen to inspection before they go out. Processing of veneer set must be into the warehouse by warehouse operator management, unified distribution. 3 mm board face to seam is in accordance with the V type construction. Concave type seam 5 mm; Concave type of seam at the grass-roots level surface to stick a layer of thick wood veneer, paste at the grass-roots level to batch of ash and sand. Please indicate tongue-and-groove seam tracing color evenly. It outstand the wall will not be used more than 5 cm board face with wrapping keel, as double wooden keel at the grass-roots level. Coated surface support replacement card can be used along keel keel. The cabinet, cupboard door is easy to deformation. Accordingly almirah door or other cabinet, cupboard door, as design thicker or aluminum frame can be used as the door, ultra-high doors adopt aluminum alloy keel so as to avoid deformation. Large wooden lines to prevent deformation can consider the way of the composite wood and MDF. Such as in the design of ambry is no special requirements, do not use wood veneer, can use white or wood decorative surface three polyvinyl chloride ammonia board. Article three polyvinyl chloride ammonium plate use PVC bag edge. Frame at the grass-roots level, packed hinge with willow eucalyptus wood square wood, other USES white pine, wooden doors should indicate the frame size and material. Dont put wrong hinge, hinge
