Appearance have crack, Angle and surface defects of plate winkles, and according to the pattern, color, choose after stacking respectively.
2.2.5 floor requires artistic pattern, before construction should draw the construction details, and make between example, after inspection, the only large area construction.
3 operation process
3.1 process:
Basic level processing to find elevation, spring wire, leveling layer mortar to play line laying brick, brick - >

Tick off seam, wipe the seam - maintenance - skirting board installation
3.1.1 basic level processing: will the cleaning out of the concrete base, with a chisel shave mortar landed grey, use wire brush to brush the net floating pulp layer. Applications such as base oil, 10% caustic soda water clean, and clear water in a timely manner on the lye rinse.
3.1.2 find elevation, elastic line: according to the wall of + 50 cm level elevation lines, downwards of surface elevation, and play on the wall.
3.1.3 plastering mortar screed-coat:
3.1.3.1 sprinkler moist: on the clean up good base, the ground with watering can uniform sprinkler again at the local level.
3.1.3.2 plaster the bread and the reinforcement: from the play good surface amount to screed-coat epithelium below sea level elevation (surface elevation minus brick thickness and the thickness of adhesive layer), plaster bread spacing l. 5 m, flat on ash cake is the elevation of cement mortar screed-coat then begins to wipe the reinforcement from on one side of the room (also called screed). Around the room with a floor drain, should by radiate towards floor drain the tendons, and looking for a good grade. Rendering the bread and the reinforcement should use harsh mortar, should not be less than 2 cm thick.
3.1.3.3 pack file (that is, between the reinforcement cement mortar) that holds a store: wipe clean the reinforcement of residual slag slurry, besmear again the slurry water to cement ratio (0.4 ~ 0.5) bonding layer, should besmear to brush with mortar. Then according to the elevation of the reinforcement with xiaoping spade or wood float will have mixing cement mortar (mixing ratio is 1:3 ~ 1:4) shop is between the reinforcement, using wood float lay flat, solid, small wood poles, leveling with wood float rub flat again, make its laying mortar and the reinforcement of leveling, with a large wooden poles check its smoothness, and check whether the elevation and slope of water right, water maintenance after 24 h.
3.1.4 play tiles line: when leveling layer mortar compressive strength is 1.2 MPa, start here line of brick. In advance according to the design requirements and brick plate size, determine the gap width of plate paving, when the design has no rules, the shop is stuck gap width should not be greater than the LMM, virtual joint pavement crack width should be for 5 ~ 10 mm.
Points in the room, from longitudinal and transverse directions in size, when multiple size less than the whole brick, will the whole brick used in the corners, in the first row of the transverse parallel to the door should be the whole brick, will the whole brick in position against the wall, and the longitudinal (vertical) at the door should be in the room, not the whole emissions in the two wall brick symmetry. According to the number of brick have been identified and seam width, longitudinal and lateral line on the ground to play a control line (every 4 bricks play).
3.1.5 tiles: in order to find a good position and elevation, and should be started, the longitudinal to lay 2 ~ 3 lines of brick, as the muscle pull level elevation lines, auxiliary from inside to outside the back operation, brick paved surface shall not tread from the start, each brick should be with line, the operation procedure is:
Before 3.1.5.1 paving brick plate into the half bucket soaking wet, dry surface without MingShuiShi, after just can use.
3.1.5.2 screed-coat sprinkling water on the wet, plain cement paste evenly (water cement ratio of 0.4 ~ 0.4), besmear brushs area is not too big, how far shop brush.
3.1.5.3 in combination with the thickness of the layer, such as using cement mortar laid for 10 ~ 15 mm, using asphalt cement laying should be 2 ~ 5 mm, using adhesive laid should be 2 ~ 3 mm.
3.1.5.4 combined with mixing layer composite materials: using asphalt cement materials and adhesives, except by the factory manual operation should also determine the mixture ratio, after laboratory test batch to mix evenly, can not have dust, a batch may not too much, and finished within the required time. If use the binding layer of cement mortar, the appropriate mixing ratio is 1:2.5 (cement, sand) harsh mortar. Should also be increases with the increasing mix use, prior to the initial setting out, prevent influence cementing quality.
3.1.5.5 paving, brick facing up on the back of bonding mortar, paving to brush has good slurry on the leveling layer, brick stare blankly on the slightly higher level elevation lines, looking for positive, after looking for straight, square, brick above board, pat solid, with a rubber mallet retreated inside the order from the outward paving, brick and mortar fullness, connect closely, solid, and floor drain and sawing with grinding wheel to turn brick and floor drain. Paving brick, a best one shop, in construction of large area, section, division of the pavement should be taken.
3.1.5.6 dial sewing, finishing: spread line 2 to 3, shall, from time to time, pull check seam, straightness, such as within the prescribed shall promptly repair, will straight seam, with a rubber mallet shot. This work should be done before combining layer of condensation.
3.1.6 seam jointing brush: surface pavement should be carried out within the 24 h seam, tick off seam, and should be adopted and the varieties, and the label, and color of the cement.
3.1.6.1 jointing: 1:1 fine cement mortar jointing, 1/3 of the thick seam depth within appropriate for brick, mortar seam in dense, smooth, smooth. Along with the hook with the remaining cement mortar removed, rub-up.
3.1.6.2 brush seam: such as design requirements without cracks or cracks is very small, insist on seam straight, dressed in the shop brick paste pot of water to sew in mud on the surface, then use dry cement in sew, reoccupy cotton ball rub rub, will wipe with cracks. The last clean the slurry on the surface.
3.1.7 maintenance: spread brick after 24 h, water conservation, the time should not less than 7 d.
3.1.8 set stick baseboard: skirting board brick, generally USES the piece of varieties and specifications, with the ground with the color of the material, the vertical seam of skirting board shall be the seam alignment, the ground should be laid on the two end Yin Angle in each room metope stick a piece of brick, wall thickness and height should comply with the design requirements, to stare blankly for a standard line brick, start the shop is stuck, brick back up with binding mortar (mixing ratio is 1:2 cement mortar), it is advisable to make the mortar with the whole piece of brick, timely to paste on the wall, brick on stare blankly with line and immediately take a firm, will scrape off extrusion of mortar, then will be clear clean surface (before pasting, brick material to flooding to dry, metope brushs water wet).
3.1.9 winter construction: interior operation temperature is not lower than + 5 ℃. Outdoor operation, should according to the temperature change of antifreezing admixture, but must note to operate after the laboratory test.
4 quality standards
4.1 ensure projects:
4.4.1 all kinds of surface plate used in the variety, quality must meet the design requirements.
4.1.2 the combination of surface and base (bonded) must be strong, no empty drum.
4.2 the basic items:
2 all kinds of the surface of the plate surface clean, clear design, colour and lustre is consistent, uniform seam, straight, surrounding the plate no crack phenomenon such as fall off, and the lack of stare blankly.
4.2.2 floor drain and eliminate liquid with the ground of the slope, slope should comply with the design requirements, not water, no water, the floor drain (pipe) attaches tight and firm, no leakage.
Holdings skirting board surface clean, uniform seam formation, highly consistent, combined with the strong, the wall thickness is appropriate, are basically identical.
4.2.4 stair step and the steps of the shop is stuck gap width is consistent, the adjacent two step difference less than 10 mm, prevent slippery straight.
4.2.5 the edge of pectin on the surface, materials of various sizes comply with the design requirements and construction norms, edge neat, smooth.
4.3 allowable deviation project, are shown in table 7-14.

Cement tile, quarry tile, the ground allow deviation (mm) table 7-14
Will project tiling quarry tile testing method
Surface roughness, 3, 4, 1 in 2 m by feet and wedge feeler check
2 seam straight line 3 3, 5 m, less than 5 m's line and the ruler quantity check
3 seam height difference of 0.5 0.5 feet and wedge feeler check
4 play crural line flowing straight line, 4, 5 m, less than 5 m's line and the ruler quantity check
5 plate gap width is not more than 2 2 feet quantity check

5 finished product protection
5.1 in the process of pavement plate operation, installed good door frames, the pipe should be protected, such as frame nail protection sheet, and start using narrow vehicle, etc.
5.2 cut the floor tile, may be just good paving brick surface operation.
5.3 when the pavement mortar compressive strength of 1.2 MPa, can master cheng yen, but must pay attention to paint, mortar shall not be stored in a plate, iron pipe hard ware, shall not touch bad brick surface. When you spray on surface cover protection.
6 should pay attention to quality problems
6.1 plate empty drum: grassroots cleanup not net, uneven water wet, brick is not flooded, the area of the cement layer combination brush too much air drying trend isolation effect, here early to factors influencing the strength of adhesive layer, and so on, are the cause of the empty drum.
Skirting board empty drum reasons, besides the same with the ground, but also because skirting board on the back of the binding mortar quantity is little not to edge, edge horn empty drum.
6.2 skirting board out of the wall thickness is not consistent: as the wall plaster verticality, smoothness, exceed the allowable deviation, skirting board set to stick in the horizontal line control, so the wall thickness is not consistent. So before with stick, first check the wall roughness, after processing to stick.
6.3 plate surface unclean: mainly after finish coat, finished product protection is not enough, the bucket on the floor tile, mixing mortar, brush on the floor tile pulp without cover, etc., are causing contamination on the surface.
6.4 have a leak down slope: do mortar screed-coat, did not play according to the design requirements of the water slope line slope. So you must looking for elevation, bullet line looking for a good grade, rendering the bread and the reinforcement, wipe out the water.
Ground brick, in 6.5 height difference: the floor tile not pick in advance, do not match the thick brick caused by difference of on any account, or when the shop is stuck not strict control according to level elevation lines.
7 quality records
This technology standard should have the following quality records:
7.1 all kinds of floor tile factory certificate.
7.2 adhesive factory to prove and test data.
7.3 cement factory certificate.
7.4 the sand silt content test records.
