5. Generally, granite pavement is constructed on the concrete cushion. Firstly, the elevation is measured to determine the height,
generally, 1:3 cement mortar (dry and hard type) is used for pavement. After a certain thickness of mortar is paved, the granite slab is covered on it, and the rubber hammer is used to knock it. After the mortar is dense, the granite slab is lifted and the cement paste is applied on the bottom. Put it on the mortar surface and strike it flat with a rubber hammer< 1. Marble (granite) building and floor belong to high-grade decoration, so there must be pattern and block design, and the higher requirements should be combined with the wall and ceiling practices and adapt to the function of the room, and the color is also the key to control the decoration effect of marble (granite) building and floor, in case of inconsistency with the design intention; For a large area of buildings and floors, we should also inspect the stone batch of the manufacturer to avoid different colors in the same room. Marble texture is soft, low strength, in processing and construction must pay attention to. Decoration building, ground for color, material, pattern of high requirements, avoid using good stone did not show good effect
2. After entering the site, the marble (granite) plates should be stacked in the room, with smooth surface opposite to each other. The back side should be padded with loose wood strips, and the wood square should be added under the plate. After unpacking, the variety, specification, quantity and radioactive substance detection report of the stone should be checked in detail to see if they meet the design requirements. If there are cracks, missing edges, corners, warping and surface defects, they should be removed. Finish the ground cushion and reserve the thickness of grinding stone layer (at least 3mm) according to the elevation

III. process flow
preparation → base treatment → trial assembly → snapping line → trial arrangement → brushing cement slurry and laying mortar binding layer → laying marble plate or granite plate → joint pouring According to the construction detail drawing and processing sheet, carefully check the size and practice of each part, and calculate the size of each detail and the corner of the hole. If there is off-site processing, the color and pattern of the stone should be inspected, and the radioactivity of the stone should be detected
(2) base course treatment
clean up the sundries in the ground cushion, check the base course for hollowing, and use a marble machine to cut off the hollowing part and pour it again. The mortar on the cushion shall be removed with tools and cleaned
(3) trial assembly
before the formal laying, the marble (granite) plates in each room should be trial assembled according to the pattern, color and texture, and attention should be paid to the pipe cutting; The non integral boards are symmetrically arranged near the wall of the room, and then numbered and stacked neatly
(4) snapping line
generally, the floor and floor construction is after the wall plastering, so before the plastering construction, it is necessary to snap the room cross control line on the base to control the room squareness, so as to prevent the inclined bars and blocks at the corners ring the floor and floor construction. The cross control line shall be snapped on the concrete cushion and led to the bottom of the wall, and then the surface elevation shall be found out according to the wall ＋ 0.5m horizontal control line, and the horizontal elevation line shall be popped on the wall. When snapping the horizontal line, the indoor and corridor surface elevation shall be consistent< (5) trial layout
lay two dry sand belts in two vertical directions in the room, the width of which is greater than the width of the plate, and the thickness is more than 3cm. Arrange the marble (granite) plates according to the construction detail drawing and the actual size of the room, check the gap between the plates, and carefully check the position and color of the mosaic parts
(VI) brush cement slurry and lay mortar binding layer
after the trial row, remove the dry sand and plate, clean them, spray water with a watering can, and brush a layer of plain cement slurry (the water cement ratio is 0.5, do not brush too much area, and brush with the mortar). Pull the cross control line (fish line) and lay the leveling layer with 1:2-1:3 dry and hard cement mortar (the dry and hard degree should be kneaded into a ball by hand and scattered on the ground). After paving, it should be leveled with ruler board, and then leveled with trowel. The area should be about 3M2. The thickness is controlled to be 3-4mm higher than the horizontal line of the surface layer when the marble (granite) plate is placed< (7) marble (granite) plate
the plate shall be soaked with water in advance, and the surface shall be dry without open water before paving
according to the cross control fishline drawn in the room, one line is laid vertically and horizontally, which is used as the standard reinforcement for large-area paving stone. According to the number, pattern and gap (generally within LMM) ring trial assembly, paving shall be started at the intersection of cross control line. Trial paving first, that is, lifting the plate, aligning the vertical and horizontal control line, laying it on the paved dry and hard mortar leveling layer, and knocking the wood base plate of the plate with a rubber hammer (it is not allowed to directly knock the plate with a rubber hammer or wood hammer to avoid cracking or breaking the plate)
after vibrating the mortar to the laying height, lift the plate to one side to check whether the mortar surface is consistent with the plate. If any void is found, fill it with mortar, and then pave it formally. Scrape a layer of cement mortar (1:0.5) on the back of the plate. When laying the plate again, the four corners fall down at the same time. Tap the wood pad on the plate with a rubber hammer or wood hammer, and level it with a ruler according to the horizontal line, After paving the first block, pave it to both sides and backward direction in sequence. After finishing the vertical and horizontal paving, there is a standard, which can be paved in sections and areas in turn. Generally, the room should be paved from the inside to the outside, and graally retreat to the door. Pay attention to the coordination and intersection with the corridor joints
in the past, dry and hard cement mortar was used to make the surface smooth. Generally, the cement mortar was paved thick (40-70mm) and trial paved after the mortar was paved. The process is complex, and maintenance is required after laying. The improvement methods are as follows:
L. to ensure the accurate elevation of the floor base, the thickness and elevation of the floor should be strictly controlled when pouring the concrete floor
2. The specifications and dimensions of stone processing should be strictly accepted according to the regulations. High strength and fast hardening mortar can be used, and rubber or additives can be added to rece the curing time. The base concrete must be kept moist before laying
3. In addition, when paving stone with cement mortar, it is easy to proce large area of water pollution (permanent), even yellowing and other adverse phenomena, which will have a very bad impact on the appearance. In order to eliminate this kind of common disease, we can carry out anti pollution treatment on the stone. We can use stone anti pollution agent to brush or spray on six sides of the stone, and the anti pollution agent can penetrate into the stone for several millimeters, It plays an important role in the prevention of stone pollution< (8) grouting and joint wiping
grouting and joint wiping shall be carried out in 1-2 days and nights after the slab is paved. According to the color of marble (granite), select the same color mineral pigment and cement, mix them evenly, mix them into L: l thin water slurry, slowly pour them into the gap between the plates with slurry pot (which can be carried out several times), and use long handle scraper to scrape the cement slurry flowing out to the joint and smooth the plate surface. At the same time, wipe the cement slurry on the plate surface to make the surface of marble (granite) surface clean, Cover and protect the surface layer. The curing time was 7 days< (IX) waxing
only when the cement mortar bonding layer reaches the strength (when the compressive strength reaches 1.2MPa) can it be waxed, the surface is cleaned, the waxing is wrapped in the cloth with wax, and a thin layer of wax is applied on the surface layer. After it is dry, it is waxed with a stone grinder nailed with canvas or linen cloth, and it survives twice
(x) skirting board process flow
for marble (granite) skirting board, when plastering on the wall, a certain height should be set aside (generally, the upward amount of the floor is 150 mm), so that the thickness of the skirting board out of the wall can be controlled, so the grouting method is adopted
grouting method:
according to the + 0.5m horizontal control line, measure the horizontal line of the upper opening of the skirting board, snap it on the wall, and then hang the line with a line drop. Determine the thickness of the skirting board out of the wall, generally 8 ~ 10 mm. Pull the horizontal line of the upper opening of the skirting board, install one skirting board at each end of the wall, the height of the upper ridge is within the same horizontal line, and the thickness of the skirting board out of the wall should be consistent, and then install it one by one in sequence, and check the levelness and perpendicularity of the skirting board at any time. Gypsum is used to stabilize the adjacent two pieces, the skirting board, the ground and the wall
pour 1:2 thin cement mortar, clean the overflow mortar at any time, and shovel off the gypsum after the final setting of the poured cement mortar
wipe the seam with cotton thread dipped in the thin water slurry with the same color as the skirting board, and wax the surface of the skirting board together with the ground. The method refers to the above manual work. The skirting board should be inlaid. The board seam should form a riding seam with the marble (granite) board seam on the ground. Pay attention to the angle grinding at the external corner, and leave 4mm to ensure that the external corner has an equilateral right angle gap; The internal corner ensures that the large skirting board is pressed against the small skirting board< When transporting marble (granite) plates and cement mortar, measures should be taken to prevent collision with finished walls and doors
in the process of paving marble (granite) plate, the operator should use dry cloth to clean the traces of cement slurry on the stone surface
when walking on marble (granite) ground, the compressive strength of cement mortar of leveling layer shall not be less than 1.2MPa
after the completion of marble (granite) floor, the room should be closed or covered with protection< 6. Quality problems that should be paid attention to
1. Hollowing of board surface: e to the following factors: the cleaning of concrete cushion is not clean or the watering is not enough, the plain cement slurry is not uniform, the brushing area is too large and the time is too long, it has been air dried, the dry and hard cement mortar is added with water arbitrarily, and the surface of marble board is not soaked with water. Therefore, we must strictly abide by the requirements of the operation process, based on
generally, 1:3 cement mortar (dry and hard type) is used for pavement. After a certain thickness of mortar is paved, the granite slab is covered on it, and the rubber hammer is used to knock it. After the mortar is dense, the granite slab is lifted and the cement paste is applied on the bottom. Put it on the mortar surface and strike it flat with a rubber hammer< 1.

There are two drilling methods:
1. When drilling with percussion drill:
when drilling with percussion drill, the gear of percussion drill should be replaced with non hammer gear, and the drilling should be done slowly, and the drilling position should not be too close to the edge of marble. This method is mainly suitable for places with small aperture. The utility model relates to a diamond coating bottle opener which can open both glass and stone
extended data:
marble maintenance
1. Marble is very fragile and is afraid of the impact and knocking of hard objects, so we should pay attention to prevent heavy objects such as iron from hitting the stone surface, so as to avoid pits and affect the appearance. Stone and granite are easy to clean and maintain. When you are free, you only need to use some cleaning agent to clean the surface, which can keep it fresh and lasting
2. Wipe the table with a slightly wet cloth with mild detergent regularly, and then dry and polish it with a clean soft cloth. When the surface is stained, it is better to clean the stains with some light corrosive agents such as lemon juice or vinegar. Never use soap or soda powder and other vulnerable materials to wipe
The retention time of lemon juice should not exceed 1 minute. If necessary, repeat the operation, then wash and dry it. For cosmetics, tea and tobacco stains, apply hydrogen peroxide, stay for two hours, then clean and dry. For oil stains, use ethanol (alcohol), acetone (Xylin) or lighter oil to wipe, and then clean and dry. If the marble furniture is burnt by cigarette butts, it should be considered for repair For marble furniture with slight scratch, special marble cleaner and care agent can be used; Marble furniture with serious wear and tear is difficult to handle. It can be wiped with steel wool, and then polished with electric polishing machine to restore its original luster. Old or valuable marble furniture should be handled by professionals5. The painted marble furniture must be treated with paint peeling agent and carried out according to the proct instructions. After all the paint has been removed, it is rubbed with steel wool and polished with an electric grinder
precautions:
1. The stone surface should be dry and smooth. After renovation, use animal wool pad or nano wool pad as far as possible to dry the ground, and then do crystal surface treatment when the ground temperature is about 50 ℃
2. Use clean steel wool and cleaning pad
The machine should be stopped immediately when the stone is shining4. It is better to use neutral crystal face agent and neutral reconditioning slurry
7.
1. First of all, we need to make a line at the place where the granite plate is drilled, so that the drilling will not deviate

Granite and granite should be bonded with dolomite glue
nowadays, marble glue has been widely recognized by stone users and construction instry. It is suitable for bonding between various stones or repairing cracks and broken marks on the surface of stones. It is commonly used in all kinds of stone laying engineering and repair, bonding positioning and caulking of all kinds of stone
The excellent properties of dolomite adhesive are mainly reflected in hardness, toughness, rapid curing, polishing, weatherability and corrosion resistance. However, e to its poor water resistance and rability, it will shrink in the curing process. According to the construction specifications, marble glue is generally not used as structural glue, but is usually used for rapid positioning or stone repair
extended data:
precautions for using dolomite adhesive:
1. The ratio of adhesive and curing agent is 100:2-4, with the best comprehensive performance. The proportion of curing agent is not the greater the better. If it exceeds this ratio, the dolomite glue will solidify too fast, resulting in low bond strength, loose solidified procts, yellow, opaque and waste procts
When the ratio is 100:2-4, the more the amount of curing agent, the faster the curing speed, which is 16-8 minutes3. In order to achieve the best use effect, small-scale test should be carried out first, and the addition amount should be controlled according to the time required by the indivial, and then batch proction operation should be carried out

sawing process is to use a sawing machine to cut granite blocks into rough boards (generally 20 mm or 10 mm thick), or semi-finished procts with strip or block shape. This process is a rough processing process, which has a great impact on the plate rate, plate quality and economic benefits of the enterprise
the main processing equipment in the sawing process are the frame type large-scale automatic sanding saw for granite, multi blade bidirectional cutting machine, multi blade computer-controlled granite cutting machine and granite circular sawing machine, etc
2) lapping and polishing
the purpose of lapping and polishing is to further process the sawn wool board to meet the requirements of thickness, flatness and glossiness. This process first needs rough grinding and leveling, and then graally through semi fine grinding, fine grinding, fine grinding and polishing, to fully display the color and texture of granite
the main processing equipment are: automatic multi head continuous grinder, diamond leveler, bridge mill, disc mill, reversing roughing mill and walking mill
3) cutting processing
cutting processing is to use the cutting machine to cut the rough plate or polished plate according to the required size< The main processing equipment is longitudinal multi blade cutting machine, transverse cutting machine, bridge cutting machine, cantilever cutting machine, hand cutting machine, etc.
4) chiseling processing
chiseling processing is a traditional processing method, through wedge cutting, chiseling, chopping, trimming, grinding and other methods, the hair embryo can be processed into the required procts, and its surface can be pineapple surface, longan surface, litchi surface, natural surface Mushroom noodles, ravine noodles and so on
chiseling is mainly done by hand, such as hammer, chopping axe, chisel, chisel, etc., but some processing processes can be completed by machine, and the main equipment is stone chopper, planer, automatic hammer chisel, automatic sand blasting machine, etc
5) singeing
singeing, also known as firing and spray firing, is to use the difference of thermal expansion coefficient of different mineral particles of granite to make some particles on the surface of granite crack and fall off by flame spray firing, forming unlating and orderly rough decoration. This kind of rough granite plate
is very suitable for the ground decoration and outdoor wall decoration in wet and slippery places
the main equipment is granite automatic singeing machine
6) auxiliary processing
auxiliary processing refers to grinding, chamfering, opening holes, drilling, groove milling, edge milling, etc
the main processing equipment includes automatic edge grinding and chamfering machine, profiling milling machine, thin-wall drilling machine, hand-held diamond circular saw, hand-held polishing machine, etc
7) inspection and repair
Natural granite will inevitably have cracks, holes and other defects, and there will inevitably be some bumps and small defects in the processing process. Therefore, after processing, all granite plates need to be inspected. First, they need to be cleaned, and then they need to be dried. Qualified procts should be packed and put into storage, while unqualified procts should be picked out first. In the case of meeting the order requirements, some granite procts with less serious defects can be repaired, that is, bonded and repaired, so as to rece the scrap rate.
