Detailed ways

The embodiment is shown in Figures 1 and 2. The process is: cleaning the base - brushing the interface agent - applying the polymer adhesive - pasting the insulation board - applying the first polymer anti-cracking mortar - hanging the galvanized steel wire mesh , Install nylon expansion bolts - apply a second layer of polymer anti-cracking mortar - apply tile adhesive - paste exterior panels.

Specific examples: (polystyrene board thick plastering system exterior tiles)

1. Base treatment: The concrete residue and release agent on the wall must be cleaned up, and the part of the wall whose flatness is out of tolerance should be chiseled or repaired.

2. Brush interface agent: After the base wall is cleaned, fully stir the interface agent and evenly brush on the base wall to enhance the adhesion between the wall and the adhesive layer.

3. Control line hanging reference line: According to the design of the building facade and the technical requirements of the external wall insulation, the horizontal and vertical control lines and expansion stitches of the outer doors and windows are popped up on the wall, and the decorative stitches are hung vertically at the large corners of the outer wall of the building. Benchmark steel wires, horizontal wires are hung at appropriate positions on each floor to control the verticality and flatness of the walls.

4. Preparation of polymer mortar: prepare plastering mortar powder and water at a weight ratio of 4:1, and stir evenly with an electric mixer.

5. Paste the polystyrene board: Lay it horizontally from bottom to top, and use the point sticking method to ensure that the bonding area between the polystyrene board and the base wall reaches more than 50%. Immediately after coating, stick the insulation board on the wall, and then use a 2-meter ruler to flatten it to ensure its flatness and firm bonding.

6. The first layer of plastering construction: use the prepared polymer anti-cracking mortar for overlay plastering, and the thickness of the mortar is 6-10mm.

7. Installation of anchors and galvanized steel wire mesh: Drill holes with an electric hammer, the holes are arranged in a plum blossom shape, and the number of anchors installed is 7 per square meter, as shown in Figure 2. After the anti-cracking mortar is basically hardened (24h), cut the galvanized steel wire mesh according to the structural size, and lay it in sections. The spacing distance between the wire mesh and the insulation board, and then install the anchors into the holes.

8. Plastering construction: use the prepared polymer anti-cracking mortar for overlay plastering, and the thickness of the mortar is 6-10mm. Wire mesh and anchors should be covered.

9. Paving and pasting exterior wall tiles: Paving and pasting exterior wall tiles is carried out from bottom to top. Place a ruler (bottom ruler) at the position of the bottom layer of bricks, and use a level ruler to correct it, so as to support the first When batching bricks, draw a horizontal line on the top of the brick skin as a standard for paving. Use tile adhesive on the back of the bricks, and stick the bricks on the wall at the correct position. After the bricks are placed on the wall, use a small spatula to gently tap and flatten them to make them attached to the line, and then use a steel sheet to open the knife to adjust the vertical seam , and use the bar ruler to adjust the verticality of the brick surface through the standard point.

The above embodiments are used to illustrate the purpose, technical content, features and effects of the utility model, and the protection scope of the utility model is not limited to this embodiment.
