Specifications and properties of five-sided ceramic tiles are made of tightly organized clay by extrusion, dry pressing, drying and baking, and are used as plate-shaped ceramic building materials for paving. The colors of floor tiles are generally white, red, light yellow and dark yellow. There are three shapes: square, rectangle and hexagon, glazed and unglazed. Floor tiles have the advantages of uniform color tone, flat brick surface, easy cleaning, corrosion resistance and wear resistance, convenient construction, etc., and can be arranged in various patterns with good decorative effect. Suitable for floors, stairs, outdoor floors, steps, indoor halls, kitchens, bathrooms, bathrooms, kitchens and other places with frequent traffic. Second, the construction preparation and working conditions 1, wall, cylinder flatness, verticality, arc angle and window position inspection. Clean the wall and cylindrical base, then wash your feet, hands and eyes and block them tightly. The walls and cylinders with too many concavities and convexities that do not meet the requirements of verticality and flatness should be chiseled neatly without leveling with cement mortar. 2, the brick quality inspection and acceptance, unqualified brick shall not be delivered. On-site acceptance should also be carried out after the bricks are transported to the site. It is required that the specifications and dimensions of ceramic tiles are consistent, with straight founder, complete edges and corners, neat edges, no warping, glaze dropping, cracks, uneven concave and convex defects, and uniform surface color of ceramic tiles. 3. All tiles must be selected one by one with special tools before construction. Number them according to specifications, size, thickness and color depth, and pile them up neatly. Do not meet the requirements of the brick should be removed, shall not be used. 4. Before construction, design the arrangement of ceramic tiles and draw the construction drawings. 5, ready to all kinds of machinery, equipment, utensils and hand tools. Third, the process of cleaning the wall-watering and wetting the wall-looking for rules on the surface-plastering the bottom layer-arranging bricks, dividing grids and elastic lines-setting decorative tiles-cleaning the surface layer-pointing-cleaning the wall. Four, the construction points and instructions. 1, clean the wall and cylinder, float ash and residual mortar should be rinsed clean, and then fully watered and wet. 2, column and metope of Yin and Yang Angle corner, all need to pull the vertical line and contour. Yang Angle to pull a double vertical line, doors and windows to pull a horizontal line. 3, according to the hanging line situation and the requirements of the tile size arrangement, render ash, render ash construction in two times. Cement mortar is mixed by mortar machine, and the ratio must be accurate. 4, after the completion of the foundation ash should be water conservation, stay behind the foundation ash reaches a certain strength can be set with tile. According to the requirements of brick row frame width, ink lines will pop up on the leveling layer frame, and lead wires will be hung vertically. Non-integral bricks are not allowed. 5. The day before tiling, soak the tiles in a bucket, take them out 1-2 hours before use, dry the surface moisture, and wipe off the floating ash on the surface for later use. 6. The order of tiling is from top to bottom, with the building layering as the boundary, one layer is completed first and then the other layer is completed. When pasting the first layer of brick, level the brick bottom with a ruler to keep the head angle straight and the joints straight. After pasting the first layer, check the flatness with a ruler. When the second layer of brick is pasted, the mortar on the first layer of brick should be leveled, the first layer of brick should be put down, the vertical and horizontal joints should be aligned, and then the shop should be laid after the verticality is aligned. The operation method is as above. 7, pointing should be carried out after the first-class brick set. A special chisel should be used for jointing, so as to ensure that the brick joints are consistent in depth and smooth in surface. Brick joints must be plastered and compacted to prevent cracks from flooding. 8, after the completion of the tile, and then clean the surface of the tile, completes the finished product protection. Five, quality requirements and control points 1), the varieties, specifications, colors and quality of ceramic tiles should meet the design requirements and construction acceptance specifications. 2), brick set stick firmly without empty drum phenomenon. Smooth and clean surface, consistent color, no deformation, alkalization, stains and obvious gloss damage. 3), joint filling embedded dense, smooth, consistent width, consistent depth, consistent color. 4), brick wall surface flatness allowable deviation is 2 mm; The allowable deviation of vertical degree of facade is 3mm outdoors and 2 mm indoors; 5), Yang Angle founder allowable deviation value is 2 mm; ; 6) The allowable deviation of brick joint straightness is 2 mm indoors ... Inspection method and quality standard of intransitive verbs: 1. Inspection lot division: every 50 rooms (rooms with large area or walkways with an area of 30M2) in the wall tile paving project are divided into one inspection lot, and less than 50 rooms are also divided into one inspection lot. Each inspection lot shall be at least 65438 00% and not less than 3; Less than 3 rooms should be fully inspected. 2. Allowable deviation and inspection method: inspection method for allowable deviation of sectional works 1 2m straightedge for 2mm vertical verticality and 3mm flatness; Yin and Yang Angle of 3mm with a square; Use 5m line for seam flatness of 2mm. If it is less than 5m, use steel ruler to check the flatness of 5 panels and bridle feet. If it is less than 5m, pull the 5m wire by 2mm. Check 6 joint height difference of 0.5mm with steel ruler; check 7 joint width 1mm with steel ruler; check 7. Common quality problems and preventive measures: common name preventive measures: uneven seams and unsmooth surface texture. The color difference is 1. Before installation, the warped and angular plates should be removed, and each plate should be checked with a set of square ruler. 2. Check and adjust each working procedure with a ruler to make the surface smooth. 3. Each batch of boards should be consistent in texture and coordinated in color, and the spare walls should be numbered 1. The handling and stacking process must be upright to avoid corners. Large blocks should be transported horizontally. 2. Light-colored plates can't be packed with straw rope. Plastic film should be covered during construction, mortar or rubber compound should be pasted during construction, and it should be wiped off at any time. 3. After the plate construction is completed, all external corners shall be protected with 2m-high boards to prevent the plate from cracking. In the process of material selection and processing, defects such as color lines, hidden seams and hidden injuries should be eliminated. When machining holes and holes, the slots should be made too thin. 2. There should be a gap between the top plate and the bottom plate, so as to avoid the slab from cracking due to impermissible settlement. 8. Occupational health, safety and environmental protection measures: 1. When entering the construction site, you must wear a safety helmet and fasten the wind rope. 2, aerial work must wear a seat belt, on the shelf before operation must check whether the scaffold is safe and reliable, confirmed rear can operate on the shelf. 3. The temporary power lines on the construction site must be laid in accordance with the electricity consumption specifications. It is forbidden to pick up and pull at random. Long-distance cables must not be pulled indiscriminately, and must be fixed overhead. 4, small electric tools, leakage protection must be installed. When the device is in use, it can only be operated after the test run is qualified. 5, electrical equipment should be grounded, zero protection, on-site maintenance electrician should hold relevant certificates, maintenance electrician shall not be connected to the power supply. 6, power supply, voltage must be consistent with the nameplate voltage of the motor, the motor should be powered off before movement, and the power switch must be turned off after work or after use. 7, welding construction must be in strict accordance with the requirements of construction technical disclosure related certificates, wear safety fire prevention measures. 8, the construction must be carried out in accordance with the construction site safety technical disclosure. 9. Dust operation is strictly prohibited on the construction site. When cleaning, it is necessary to sprinkle a small amount of water to wet the rear, and pay attention to the protection of finished products. Waste materials and garbage must be cleaned up in time, bagged and transported to the designated stacking place, and the garbage dump must be in Dang Wei.
