1, exterior wall insulation board construction quality requirements include:

(1) The varieties, specifications and quality of thermal insulation materials shall meet the design requirements;

(2) the insulation layer thickness is uniform, and the construction method should meet the design requirements;

(3) The insulation layer shall be firmly bonded with the wall and various structural layers, without delamination, hollowing and cracks, and the surface layer shall be free from pulverization, ash explosion and peeling;

(4) The anti-crack mortar has no ash leakage, and the grid cloth is evenly pressed into the anti-crack mortar without leakage. Lap and special parts of steel comply with the design requirements;

(5) The surface shall be clean, smooth and free from obvious lines, and the line angle shall be straight and clear;

(6) The positions and sizes of doors, windows, holes and boxes are correct, and the surfaces are clean and tidy.

2. Legal basis: Article 61 of the Building Law of People's Republic of China (PRC).

The construction project delivered for completion and acceptance must meet the prescribed quality standards of construction projects, have complete technical and economic data of the project and signed project warranty, and meet other completion conditions stipulated by the state.

Only after the construction project is completed and accepted can it be delivered for use; Without acceptance or unqualified acceptance, it shall not be delivered for use.

Second, what is the construction process of external wall insulation?

External wall insulation construction process includes:

1, grassroots cleaning. Firstly, clean up the residual ash on the wall surface and check whether there is release agent and oil stain on the wall surface;

2, metope measurement. According to the design requirements of the building facade, measure the doors and windows, vertical control line and expansion line on the wall, and hang the vertical reference line on the building exterior wall;

3. Paste the grid cloth and polystyrene board. Paste the grid cloth on the outside of polystyrene board with mortar, and use the total frame bonding method in the process of pasting polystyrene board;

4. mooring anchor. Drill a hole on the surface of polystyrene board with an electric drill, and then knock or screw the anchor nail into the interior, and the nail head and disc shall not exceed the board surface;

5, bargain hunting. If the joint of polystyrene board is uneven, first use coarse sandpaper as the base, rotate it in the circumferential direction, and then use a brush to remove impurities;

6, wipe the bottom plastering mortar. Preparing polymer mortar, firstly smearing the mortar on the bottom surface, and then pressing the folded grid cloth into the mortar;

7. lay a grid cloth. After the grid cloth is tightened, it is attached to the bottom layer and then pressed to the surface layer of mortar. In the process of pressing, it should be pressed tightly, and the grid cloth should not be wrinkled.
