3 operation process
3.1 process:
Basic level processing - hung vertically, set of square, to find the rules - stick ash cake - to play line, base with ashes
Stick the ceramic Mosaic - jie paper, adjustable seam - wipe a seam
3.2 at the grass-roots level for the concrete walls:
3.2.1 basic level processing: first of all to protrude the stuck between concrete flat of metope, concrete wall of large steel mould construction should be cut hair, filled with a wire brush to brush again, water wet again. If primary concrete is very smooth, can also use "roughen processing" approach, namely the surface dust, clean up dirt, first with 10% caustic soda water oil pollution of the metope is brushed, then use clean water to lye rinse and dry. Then fine with 1: cement mortar within 20% of the 107 glue, mix into water spray or use the broom to mortar on the wall, the left point wants even, water conservation, after the final set until the cement mortar bumps smooth on all glued to the concrete, and has high strength, break with the hand did not move.
3.2.2 hanging vertical, set square, find rules, stick ash cake: according to the wall structure roughness find out the rules of the ceramic Mosaic, if it is a tall building on the metope of all stick ceramic Mosaic, surrounded by large Angle and door window should be with a theodolite find straight vertical line; If is a multi-storey building, can start from the top line with special big fall guy wire hanging vertically, then according to the specifications of the ceramic Mosaic, sizes layered instruction, do ash cake. Horizontal lines are horizontal floor baseline loop control, vertical line around with large Angle and through the column, buttress for the baseline control between the layers. Each layer of render it as grey as a reference point for screed, make its underlying ash do horizontal flat vertical, founder. At the same time pay attention to find good eaves, waist line, windowsill, awning and other decorative surface slope and the water drip line (slot). Its depth is not less than 10 mm wide, neat and consistent, and must be the whole brick.
3.2.3 wipe base ash: base ash general secondary operations, brush a mix into 15% of the 107 first plastic cement slurry, following the first round with cement mortar, the mixture ratio of 1:2.5 or 1, 3, and 20% admixture cement weighs 107 glue, apply a thin layer, use float compaction. The second press with the same mixture ratio of mortar screed, with short poles, leveling dips TianPingBuJi beforehand, in the end, wood float to rub out the pits. Water conservation foundation ash after the wipe, the next day.
3.2.4 flare line: stick ceramic Mosaic should be released before the construction details, pop-up several horizontal line, according to the height of concrete in the horizontal line, should calculate the ceramic Mosaic blocks, kept the whole brick between two lines. Such as frame need to divide by the total height, according to the design and ceramic Mosaic set nuiko width, varieties, specifications for the frame processing again. But the same can not have a row of not more than the whole metope brick, and should be set on a hidden area.
3.2.5 stick ceramic Mosaic: post shall be carried out from top to bottom. High-rise building measures, segments. Within each section or block of ceramic Mosaic, are all from bottom to top with stick. Stick ceramic Mosaic bottom ash to water wettability, and playing good horizontal line of the mouth, on a mat on the feet, generally for a group of three people. One water wetting metope, brush on a plain water first mud down (within 10% of the 107 glue); Add 2 ~ 3 mm thick layer of mixed ash binder, the mixture ratio of paper reinforced cement, lime putty, = 1:1:2 (the paper first reinforced with lime paste stir 3 mm sieve, stir again and cement),
Also can use 1:0.3 cement reinforced paper grey, used by foot plate, leveling with a trowel smooth; Another man will spread ceramic Mosaic (piping up) on the wooden board, filling nuiko 1:1 cement fine sand ashes, with a soft brush MAO textured, with a net to wipe on a thin layer of mortar. And handed it to another person, quadrilateral ash scrape, hands of live above ceramic Mosaic, in has a good mat feet by post, nuiko alignment, should pay attention to the good relation line post. Such as frame through a set of, will continue to post article mm on the top line the second group. Set the height of the post should be according to the temperature conditions.
3.2.6 jie paper, adjustable seam: stick the ceramic Mosaic metope, want to hand clappers, depend on good on metope, in one hand and a hammer to clappers full knock again (knock, knock), then the paper with a brush on the ceramic Mosaic sheung shui, about 20 ~ 30 min, such as paper can begin to jie. After uncovering paper check whether nuiko size uniform, such as appear skewed, wrongly nuiko, should order correct paste, horizontal vertical, correct the dial straight after the first.
3.2.7 brush seam: paste after 48 h, with float first sew approximate ceramic Mosaic color clean water mud lay it seam need to wipe on ceramic Mosaic, then the slurry with a scraper scraping full, scraping the solid, in nuiko yan, reoccupy hemp yarn and clean cloth to wipe the surface. Legacy in nuiko float sand can be used wet clean soft brush out gently, if you want to finish cleaning, should can be carried out after jointing material hardening. Article on the mm nuiko to induce yan GouPing in 1:1 cement mortar, and then use clean cloth to wipe clean.
3.3 at the grass-roots level of brick walls:
3.3.1 basic level processing: plaster walls must be clean before, check the window sill and the place such as waist line, the damage and loose parts to handle, and then water wetting metope.
3.3.2 rainfall distribution on 10-12 hanging vertical, set square, find rules: and the grass-roots for concrete wall.
3.3.3 wipe base ash: base ash general secondary operation, for the first time to put on the thin layer and with a trowel compaction, cement mortar mixing ratio is 1:3, and mixing cement weighs 20% of 107 glue; Second press with the same mixture ratio of mortar screeding screed line, with a short bar, leveling dips TianPingBuJi beforehand, with wood float finally hung pits. Water conservation foundation ash after the wipe, the next day.
We ~ 3.3.7 with base for the concrete practice of metope.
3.4 for the aerated concrete wall at the grass-roots level, appropriate, choose one of the following two ways:
3.4.1 track water and aerated concrete surface, repair the lack of edge drop horn. Before repair, brush a first polymer slurry, then use 1:3:9 = cement: white plaster: layered filling sand mixed mortar, the next brush polymer cement slurry, and 1:1:6 mixed mortar base, wood float rub flat, water conservation the next day.
3.4.2 water and aerated concrete surface, in the lack of edge drop horn brush polymer cement, mortar mixed with 1:3:9 layered filling-in, after being dry, nail wire mesh layer and tighten. In online metal layered with 1:1:6 mixed mortar base (preferably adopts the mechanical injection process), mortar and metal mesh should be combined with strong, with wooden sister gently rub flat, finally the next water conservation.
Other practices with concrete walls.
3.5 summer with outdoor walls ceramic Mosaic, should have measures to prevent exposure of reliable.
Winter construction: 3.6 generally only at the beginning of the winter shi construction, stage of cold shall not put outdoor metope ceramic Mosaic inlay.
3.6.1 mortar shall not be lower than 5 ℃, the use of temperature of slurry before hardening, antifreezing measures should be taken.
3.6.2 with freezing method of masonry wall, should be the thaw rear can construction.
3.6.3 set early hardening paste mortar shall not be cold. When the temperature is below 5 ℃, outdoor setting and posted in the mortar can be mixed with admixture can reduce the freezing temperature, its infiltration amount should be determined by test.
3.6.4 radar echoes captured in order to prevent the ash layer in the early seas, and ensure the quality of operation, the mortar in the white plaster and 107 glue can't use, can use the same volume of fly ash to replace or to switch to cement mortar plaster.
3.6.5 winter indoor set stick ceramic Mosaic, can use hot air or stove chimney to accelerate drying. When the hot air is used, should be excluded from moisture, set ventilation and temperature control and management of designated persons.

6 should pay attention to quality problems
6.1 the empty drum, fall off:
6.1.1 due to low winter temperatures, mortar seas, coming after the spring thaw for ceramic Mosaic back more smooth and easy to fall off. So when making set stick ceramic Mosaic operation, should maintain temperature, outdoor ceramic Mosaic unfavorable winter construction.
6.1.2 surface deflection at the grass-roots level, basic level processing or improper construction, such as each layer of plaster with too tight; Ceramic Mosaic tick off seam is lax, and without water conservation, the bonding strength between the layers is very poor, the surface is easy to generate empty drum, fall off.
No, also 6.1.3 the formulations of cement mortar consistency control is bad, sand silt content is too large; Or on the same construction, using several different mixture ratio of mortar, and thus produce different drying shrinkage, can cause the empty drum. Standard operation should be serious in strict accordance with the process, attaches great importance to the basic level processing and self inspections, found empty drum should immediately rework heavy stick. The whole or independent part should be completed at a time.
6.1.4 divided seam uneven, metope uneven: main is not seriously before construction according to the size of the drawing to check the actual situation of the structure construction, construction of basic level processing and not seriously enough; Less bread stick ash control points at the same time, hence the metope is not smooth. Due to the elastic line brick is not fine, do not match the size each ceramic Mosaic, choose brick is not fine, improper operation, such as construction frame joints caused by uneven. Should be chosen is the same size of the ceramic Mosaic inlay on the wall. Less than a full brick left live should be deal with by designated personnel.
6.1.5 Angle not founder of Yin and Yang: the main sketch is grey, not according to the rules to hang straight, set of square, to find the rules.
6.1.6 metope pollution: mainly after check the seam mortar for failing to wipe, or due to other type of work and working procedure metope pollution, etc. Can dip in with cotton silk dilute hydrochloric acid to scrub, and then rinse with clear water.
