The quality of roof metal tile directly determines the quality of the house. Roof waterproofing plays a very important role in the construction process. The following is a detailed description of the eaves and trenches on metal tile roofs.

1. Before using waterproof coating, the metal tile roof waterproof base material should be properly treated: the metal tile roof ditch should be waterless, leak-free and uneven, and should be flat, firm, clean and cracked. Horizontal leakage must be dealt with first.

2. As a waterproof system of metal roof, polyurethane sealant should be used to pretreat the joints and bites on both sides of trench bottom and metal tile roof, and then coat them with paint to make the edge arc smooth without water accumulation.

3. Metal tile roof in the ditch of the water mouth, also do occlusion, joint closure, filling. The notebook of nozzle should not be Gaochu. If there is water, it should be treated after water treatment, and then the whole construction work should be carried out.

4. After opening the bucket, the waterproof coating should be fully stirred and stirred. The elastic closed waterproof coating should be coated once, while wetting, the woven polyester cloth should be coated once, and the bottom coating should be coated once. After the same bottom coating is dried, the surface isolation coating should be coated.

5. Scraping: Scraping with a scraper according to the design requirements of the waterproof layer.

6. Smear each corner evenly according to the appropriate amount of the bottom layer and brush it once with a hard and fine brush. After the coating is dried and solidified, polyester cloth is woven with log stick, and steel treasure protective primer is coated on the middle layer immediately. After the middle layer is dried, the sound insulation coating is brushed on the surface layer. It is suggested that the time interval between coatings should be determined by whether the coatings are dry or not. When the coating has precipitation, it should be stirred evenly at any time. The bottom of the barrel should be stirred several times during each scraping to prevent precipitation.

7. In the construction sequence, the additional layer of the joints is made first, and then the large area coating is carried out. Coatings on corners and exterior walls should be thin brushes without flow or accumulation.

8. Scraping film should be uniform, not locally deposited, need to scrape many times, so that there are no bubbles between the coating and the matrix, and the combination is strict.

9. According to the prescribed quantity, the material should not be too thick or too thin.

10. The optimum construction temperature should be 5-30 degrees Celsius. When not solidified after construction, attention should be paid to protection, so as not to damage the waterproof layer.

Nowadays, people's demand for beauty is increasing, especially the trend of decoration is to be beautiful and durable, and the construction of roof, people have turned their attention to the new color stone metal tile, more and more roofs are covered by it. Both villas and buildings use colorful stone metal tiles, but in high-altitude buildings, we should know some precautions, that is, to control the environment, in order to prevent inappropriate situations after completion.

In order to complete within the specified time, some construction workers are still working on high-color stone metal tiles in rainy days. In this case, first of all, reliable anti-skid measures should be taken. Second, high-rise buildings running on high-metal color stone bricks should be equipped with lightning protection facilities in advance. If the weather is bad, such as strong wind and fog, climbing and hanging in the open air should not be carried out. After typhoons and rainstorms, the facilities of colored stone metal tiles should be inspected one by one. If loosening, deformation, damage or shedding are found, it should be repaired and perfected immediately.

Another point to note is that temporary horse tracks or operating platforms have reliable connections or connections. The following covers the net, temporary railings are set on the side, kickboards are set, and mesh covers are set to prevent falling objects. When purchasing colored stone metal tile, it can reduce the bad situation in the construction process or the phenomenon of falling off after a short construction time.

Residential decoration takes a long time, and can not avoid rainy and windy weather, so we should pay attention to the control of the environment. Different weather should take appropriate measures to ensure the completion quality. This link is a more important issue, so we should pay attention to E. Notes in future construction.

Recently, a technician from a villa engineering company discovered our company and wanted to consult the roof construction in the difference between dry construction and wet construction. To solve this problem, our technical department has also solved the difference between the two roof structures.

Roof construction is mainly divided into dry construction and wet construction.

I think everyone has a general understanding of these two constructions.

In drying construction, tiles are fixed on roof by buckle, which can be fixed on inclined roof ridge or hanging tiles, so that tiles are firmly fixed, tapered tiles can be connected with tiles, and main tiles can be fixed by tap windproof buckle according to regional wind pressure and slope. Conditions. The tension system such as retaining ring can ensure the roof under extreme weather conditions; the dry construction greatly shortens the installation time, and can be constructed under severe weather conditions without special tools, thus saving the construction time; the dry construction roof is more beautiful without C. Cement mortar also reduces the overall load of roof and construction difficulty.

The traditional cement mortar is used in wet construction to fix the tiles on the roof. Wet mortar is easy to leak or even fall off after many freeze-thaw cycles and weathering, which affects the beauty of the roof. After rainwater scouring, the long-term effect of wet alkaline environment on tile will reduce the color and other properties of tile. In addition, wet construction is limited by weather conditions, which slows down the construction speed and delays the construction cycle.
