Nowadays, many of us are doing this exterior wall insulation board. It is not clear what some of our external wall insulation board construction specifications are, what are the requirements, and the clear rules, then it will cause unnecessary impact during the renovation of everyone. And damage, so we have a small series of decoration home network to tell you about the construction specifications of the external wall insulation board, as well as some guarantee items and precautions about the construction specifications of the external wall insulation board.
I. Introduction to the construction specification of external wall insulation board
1. According to the pilot scheme, the registered capital of the first-level enterprise must be more than 10 million yuan, and the highest annual project settlement income of more than 40 million yuan in the past 3 years, and construction machinery and testing equipment suitable for the scope of contracted projects.
2. The enterprise manager has more than 8 years of experience in engineering management. The technical person in charge has more than 8 years of experience in engineering construction technology management, and has senior professional titles. He has presided over the construction of 2 building energy-saving projects.
3. In the past 5 years, it has applied new technologies, new processes, new materials and new equipment related to engineering construction at the provincial and ministerial level, or has one valid patent related to the engineering construction of this specialty.
4. For the project performance of the enterprise, the method requires that the construction insulation project of more than 3 items with a single contract amount of more than 8 million yuan or the construction of a building sunshade project with a single contract amount of more than 3 million yuan should be independently undertaken in the past 5 years.
5. The standards of the second and third grade qualification enterprises are slightly lower than the first grade, but the quality requirements of the project must be qualified, and the staff must have relevant management experience and qualifications.
6. According to the enterprise's grade standard, the first-level enterprise can undertake the construction of the building energy-saving external wall thermal insulation project whose single contract amount does not exceed 5 times the registered capital of the enterprise, and the second-level enterprise can undertake the building energy-saving exterior wall with a single contract amount of more than 10 million yuan. For the construction of thermal insulation projects, the third-level enterprises can undertake the construction of projects with a contract value of more than 3 million yuan.
Second , the guarantee project of the construction specification of the external wall insulation board
1. The thickness of the insulation layer meets the design requirements.
2. Between each plaster layer and between the plaster layer and the base layer, it must be firmly bonded, free of delamination, hollow, and no cracks in the surface layer.
3. The surface of the plaster layer should be smooth, clean, smooth, and the joints should be clear.
4. The surface of the ash on the corners, holes and slots should be neat and smooth, and the surface of the ash behind the pipe should be flat.
5, the setting of the division joint should meet the design requirements, the width and depth should be uniform, the surface should be smooth, and the edges should be neat.
6. Where there is drainage, the drip line (slot) should be made. The water line (slot) should be neat and straight. The drip line should be low inside and outside, and the depth and width of the drip groove should not be less than 10mm.
7, DY inorganic active wall insulation materials on-site construction, it is strictly prohibited to add any additional materials.
8. The prepared slurry should be used with the equipment, and it should be used up to two hours. It is never allowed to be used repeatedly.
9, DY inorganic active wall insulation project during construction and within 24 hours after completion, the base and ambient air temperature should not be lower than 5 °C. Avoid sun exposure during the summer. Construction is not allowed in windy weather and rainy days above level 5.
10. Do a good job of finished product protection, avoid the rain immersion and collision on the newly constructed walls, and keep the construction site ventilated and dry. When the summer temperature exceeds 25 °C, it needs to be sprinkled for maintenance; in winter, pay attention to antifreeze and strong wind; after each construction, it is necessary to clean the construction tools and mixing equipment in time to avoid affecting the next use.
Then our Xiaobian said these contents are some important contents of the construction specifications of the external wall insulation board. I hope that everyone will follow and remember. We will know the construction specifications of these external wall insulation boards in the future, which will be of great help to us. And there is also information about other aspects of decoration that you would like to know. Our home decoration network can also bring you all.

Washers are generally flat metal rings used to protect the surface of the connected parts from being scratched by the nuts, dispersing the pressure of the nuts on the connected parts. The gasket is a mechanical seal between two objects, which is usually used to prevent the impact of pressure, corrosion and pipeline natural thermal expansion and contraction leakage between two objects. The materials of rubber gaskets usually include Nitrile rubber, styrene butadiene rubber, hydrogenated Nitrile rubber, EPDM, silica gel, fluorine rubber, neoprene, perfluorocarbon, etc. Gaskets are usually made of sheet materials, such as pad paper, rubber, silicone rubber, metal, cork, felt, Neoprene, Nitrile rubber, glass fiber or plastic polymer.
