Construction technology of glass Mosaic

glass Mosaic

The operating process of Glass Mosaic construction

1) Basic treatment: First of all, the protruding wall of the concrete flat, the large-scale construction of the concrete wall should be chiseled wool, and steel wire brush brush once again, and then watering wet, and cement: sand: interface agent = 1:0.5:0.5 cement mortar on the concrete wall hair treatment.

2) Vertical hanging, set to find rules, paste gray cake: according to the wall structure flatness to find out the rules of ceramic brocade brick, if it is a high-rise building in the outer wall of all ceramic brocade brick, should be around the big corner and door window side with a theodolite vertical line to find straight; If it is a multi-storey building, can start from the top floor with a special large line hanging low carbon steel wire hanging vertical, and then according to the specification of ceramic brocade brick, size layering set points, do gray cake. The horizontal line is controlled by the floor as the horizontal base, and the vertical line is controlled by the large corners around and the columns and crenel between the floors. The bottom of each layer is the gray cake as a Reference point for reinforcement, so that the bottom gray horizontal vertical, square. At the same time, we should pay attention to find a good highlight cornice, waist line, windowsill, rain canopy and other decorative water slope and drip line, slope should be less than 3%. Its depth is not less than 10㎜, and neatly consistent, and must be the whole brick.

3) Wipe the bottom ash: the bottom ash is generally divided into two operations, wipe the head over the cement mortar, its mix ratio is 1:2.5 or 1:3, and mixed with 20% cement weight of the interface agent glue, thin wipe a layer, compacted with a spatula. The second time with the same mix of mortar according to the reinforcement to smooth, scrape with short bars, fill in the concave in advance, and finally rub out hemp with a wooden trowel. After wiping the bottom of the gray, watering maintenance every other day. Leveling layer thickness should not be greater than 20㎜, if more than this value must be taken to strengthen measures.

4) Bullet control line: the construction sample should be released before pasting the Glass Mosaic, and several horizontal control lines should be popped out according to the specific height. When the horizontal line is played, the number of blocks to be used should be calculated to keep the number of the whole brick between the two lines. If the grid needs to be evenly divided according to the total height, the width of the suture can be determined according to the design and the varieties and specifications of ceramic tiles, and then the grid can be processed. But we should pay attention to the same wall should not have more than a row of non-integral brick, and it should be inserted in the more hidden part.

5) Glass Mosaic pasting should be done from top to bottom. Insert from bottom to top within each section or block. When the bottom ash to be watered and moistened, and in a good horizontal line on the lower mouth, support a cushion ruler, generally three people for a group of operations. A person watering wet wall, first brush a plain cement slurry, and then wipe 2 ~ 3㎜ thick mixed ash bond layer, the mix ratio for paper reinforcement: stone plaster = 1:1:2, can also use 1:0.3 cement paper reinforcement gray, by the ruler board scraping, and then wipe with a trowel; Another person laid the curtain wall glass Mosaic on the wooden support plate, filled the sutures with 1:1 cement fine sand ash, brushed the hemp surface with a soft brush, and then applied a thin layer of mortar. Then pass them to another person one by one, scrape off the ashes on the four sides, hold the ceramic tiles with both hands, stick them on the padded ruler from bottom to bottom, align the stitches, and take care to stick them along the horizontal and vertical lines. If you finish a group, put the rice stick on the top line and continue to stick the second group. The height of the veneer shall be determined according to the prevailing air temperature conditions.

6) Uncovering the paper and adjusting the seam: after pasting the wall of glass Mosaic, take the clapper in one hand, lean against the pasted wall, take a hammer to the clapper full knock again, and then brush the paper on the glass Mosaic with water, about 20 ~ 30 minutes can begin to uncovering the paper. After uncovering the paper, check whether the size of the sutures is even. If the sutures are skewed or not straight, they should be straightened in sequence, first horizontal and then vertical, and straightened until they are straightened.

7) Wipe the seam: 48h after pasting, first use a trowel to put the white cement mud on the ceramic tile to wipe the seam, and then use a scraper to scrape the cement mud into the seam full, solid and strict. Clean the surface with hemp and cloth. The floating sand left in the stitching can be gently removed with a soft, moist brush. If the finish needs to be cleaned, it should be done after the pointing material has hardened. The stitching of the rice strip should be tightly leveled with 1:1 cement mortar, and then wiped with a wiping cloth.
