A, the external wall insulation board construction specification introduction
1. According to the Trial Measures, the registered capital of a first-class enterprise must be above100000 yuan, and the highest annual project settlement income in recent three years is above 40 million yuan, and it must have construction machinery and testing equipment suitable for the contracted project scope.
2. The enterprise manager has more than 8 years working experience in engineering management, and the technical director has more than 8 years working experience in engineering construction technology management, and has a senior title, and has presided over the construction of two building energy-saving projects.
3. In the past five years, it has applied new technologies, new processes, new materials and new equipment related to engineering construction at or above the provincial or ministerial level, or has valid patents 1 piece related to engineering construction of this major.
4. For the engineering performance of the enterprise, the method requires that in the past five years, it has independently undertaken three or more building insulation projects with a single contract value of more than 8 million yuan or building sunshade projects with a single contract value of more than 3 million yuan.
5. The enterprise standard of Grade II and III qualification is slightly lower than Grade I, but the project quality must be qualified, and the staff must have relevant management experience and qualification.
6. According to the classification standards of enterprises, the first-class enterprises can undertake the construction of energy-saving external wall insulation projects with a single contract amount not exceeding 5 times of the registered capital of enterprises, the second-class enterprises can undertake the construction of energy-saving external wall insulation projects with a single contract amount of more than 6.5438+million yuan, and the third-class enterprises can undertake the construction of projects with a contract amount of more than 3 million yuan.
Second, the external wall insulation board construction specification guarantee project
1, and the thickness of insulation layer meets the design requirements.
2, between plaster layer and plaster layer and base, must be firmly bonded, no delamination, empty drum, surface cracks.
3, plaster layer surface should be smooth, clean, rub flat, frame joints should be clear.
4. The _ ash surface around the corner protector, hole and trough box should be neat and smooth, and the _ ash surface behind the pipeline should be smooth.
5, frame joint settings should comply with the design requirements, width and depth should be uniform, the surface should be smooth, edges and corners should be neat.
6. Where there is drainage, drip line (trough) should be made, waterline (trough) should be neat and straight, drip line should be high inside and low outside, and the depth and width of drip tank should not be less than 10 mm. ..
7.DY inorganic active wall insulation materials should be constructed on site, and it is forbidden to add any additional materials.
8. The prepared slurry should be prepared as you use it, and it is advisable to use it in about two hours, and it is never allowed to be reused.
9. During the construction period and within 24 hours after the completion of 9.DY inorganic active wall insulation project, the air temperature of the base and the environment should not be lower than 5℃. Avoid sun exposure in summer. Construction is not allowed in windy weather and rainy days above level 5.
10, do a good job in finished product protection, avoid rain soaking and collision on the newly constructed wall, and keep the construction site ventilated and dry. When the summer temperature exceeds 25℃, water should be sprayed for maintenance; Pay attention to antifreeze and strong wind in winter construction; Clean the construction tools and mixing equipment in time after each construction, so as not to affect the next use.
Then these contents mentioned in our small series are some important contents of the construction specification of external wall insulation board. I hope everyone will abide by it. It will be of great help to us if we know these construction specifications of external wall insulation board in the future. There are other knowledge and information about decoration that we want to know, and we also have something for you.
