Job Guide ------ Marble, granite ground construction process standard 1, construction preparation 1. ?? Material and main machine 1)? Natural marble, granite variety, specifications should meet design requirements, technology Level, gloss, appearance quality requirements, should meet the national standard "natural marble construction plate", "granite construction sector". 2) Cement: silicate cement, ordinary silicate cement or slag silicate cement, the label should not be less than 425. White cement: White silicate cement, its label is not less than 425. 3) Sand: Sand or coarse sand, the amount of mud should not be greater than 3%. 4) ?? Mineral pigment (squeezing), wax, oxalic acid. 5) Main machines: Shovel, tape, bucket, wet, ink, steel tape measure, nylon line, rubber hammer (or wood hammer), grinding machine. 2.?? Work conditions 1) ?? Marble, granite slate enters, should be placed on the indoor light surface, the back is pine, and the wooden side is placed under the plate. Detailed nuclear sessions, specifications, quantities, etc., which should be eliminated when there is cracks, defects, rolling angles, warpage and surface defects. 2) ?? Indoor plaster (including the gantry), the ground pad, the pipeline that is embedded within the mat and the pipeline through the ground is completed. 3) ?? The wall is equipped with the wall around the wall 50cm horizontal line. 4) How to draw a marble ground before construction operation. 5) ?? The operating temperature does not lower than 5 ° C during the winter period. Second, the operation process 1. Process preparations → test → Bounce → Test row → brush cement slurry and laminate binding layers → laying the slide plate (or granite plate) → Irrigation, Section → Wax 2. Preparation 1) ?? Understand the relationship between the size and the method of determination of the size and the determination of each part, the corner and other sites, based on the construction models and processing orders. 2) ?? Grass layer treatment: clean the debris on the ground pad, brush the mortar bonded on the pad and clean it with a steel wire brush. 3. ?? Test: Before formal laying, the marble (or granite) sector in each room should be tried according to the pattern, color, texture, and the non-blocks are discharged in the room, the trial Press two directions numbers, then set neutralize the number. 4. Summary: In order to check and control the position of the marble (or granite) sector, the cross control line is pulled in the room, playing on the concrete pad, and leads to the bottom of the wall, then according to the wall 50cm The high line is identified as highlighting, and the horizontal high line is pop-up on the wall. Pay attention to the indoor and the corridor level in the room. 5. ?? Test row: Two dry sands in each of the two mutually perpendicular direction, the width is greater than the plate width, and the thickness is not less than 3 cm. Combined with the construction model and the actual size of the room, the marble (or granite) sector is placed in order to check the gap between the sectors, the nucleus on the plate and the wall, column, hole, etc.. 6. ?? Brush cement slurry and lamination binding layer: After the test shop, remove the dry sand and sector, clean, sprinkle water with watering can, brush a homogenated cement slurry (water as ambient is 0.4-0.5, do not brush The area is too large, and the mortar is passed. Determine the thickness of the binding layer mortar, pull the cross-control line according to the board horizontal line, and start the binding layer of dry hard cement mortar (generally 1: 2-1: 3 dry hard cement mortar, hard-hardness, to the hair, landing Subsegrant therefrom), the thickness is controlled to be 3-4 mm from the plane level horizontal line when placing the marble (or granite) sector. After the paving, use the top bales to be flat, and then use the meat to look down (the spread area is not too large). 7. ?? Paper Marble (or granite) sector: 1) ?? The sector should be wetted with water, and can be laid after drying or drying.
2) ?? According to the cross-control line of the room, it is used as a large-scale shop. Depending on the number, pattern and tonicity of the test (the gap width between the plates, when the design is not specified, it should not be more than 1 mm), and the cross-control line is started. First test the pave, the plate is paved on the good vertical and horizontal control line on the paved dry hard mortar binding layer, knocking on the wooden pad with a rubber hammer (must not be tapped with a rubber hammer or wood hammer), vibrating After the mortar is equipped with a plate, the plate is moved to the side, check whether the surface of the mortar surface and the sector finds a problem, and the mortar is filled, and then it is officially sealed, first pour a layer on the cement mortar binding layer. The gray ratio of 0.5 is 0.5, pouring averages averaged), then pave the plate, placed in the four-corner to fall in the same time, tap the wooden cushion with the rubber hammer or wood hammer, according to the horizontal line of iron level, finished A piece, laying on both sides and backwards. After the end, there is a standard after racing, and the segmentation partition is sequentially paved, and the general room should be taken out and again, gradually returning to the door, which is easy to protect the product, but must pay attention to the corridion. You can also pave the door from the door, the plates should be tightly mounted on the corner, striped and rely on the wall, and there must be no gap. 8. ?? Irrigation, sewing: 1-2 days of grouting after 1-2 days after the plate is paved. According to the marble (or granite) color, select the same color mineral pigment and cement (or white cement) mix evenly, 4: 1 dilute cement pulp, seed pulp into the slit between the sectors (can be divided A few times), and scraped the squeegee of the squeegee to scrape the slit to the gap, until the substantially filling. After the grout 1-2 h, rub the grain plug and rubbing the raw cement pulp, and the cement pulp on the plate is cleaned, and the surface of the marble (or granite) is clean, flat, and solid. After the above step is completed, the surface layer is covered. The maintenance time should not be less than 7D. 9. ?? Wax: When the cement mortar binding layer reaches the strength (when the pressure is 1.2 MPa), it can wax. 10. ?? According to the main wall 50cm high line, measure the horizontal line of the skate board, play on the wall, and then use the wire pendant to determine the thickness of the barkerboard, generally 8-10 mm. Third, quality standard 1. ?? Guaranteed item 1) The plate variety, specifications, level, shape, finish, color and pattern must meet the design requirements. 2) The surface layer and the base layer must be firm and no empty drum. 2. ?? Basic items 1)? 9-layer polished marble and granite plate surface: the plate is strict, no gap, the seam is not wrong, the surface is clean, the pattern is clear, and the pattern is clear, and the pattern is clear, and the pattern is clear, and the pattern is clear, and the pattern is clear, and the pattern is clear, and the pattern is clearly free, The surroundings are straightforward. 2) ?? Plate stickers: Any independent space is consistent, the pattern is basically consistent. The slate sash is consistent with the colors of the slate, and the seash is full and the slate is flush, clean and beautiful. Fourth, the finished product protection 1. When transporting marble (or granite) sector and cement mortar, measures should be taken to prevent collision has been completed, and the door, etc. 2. ?? Paper, marble (or granite) sector and fragmentary marble sector, the operation procedure should be the trace of the cement slurry on the woolen plane. 3. When walking on marble (or granite) ground, the compressive strength of the flat cement mortar shall not be less than 1.2 MPa. 4. After the marble (or granite) is completed, the room should be closed or covered with its surface.
