1. The main reason for the water leakage of the color steel tile roof is: 1. Accidental deformation of color steel tile during production, transportation and construction. The quality of the color plate is poor, and the deformation of the color plate is caused by the roof construction of the master. 2, wind, rain and other external forces, resulting in long-term vibration of the color steel tile roof, so that the nail hole and iron joint wear for a long time, rust in the rain, and then wear and rust, more and more serious. 3. Why does the self-tapping nail have a rubber pad or leak water? First: the self-tapping nail was too hard during construction, and the rubber pad was damaged. Second: the rubber pad ages quickly and loses its waterproof effect soon. 4. The main reasons for the deformation of the color steel tile roof are as follows: First, the large span of the roof causes water accumulation in the middle, and the gravity in the middle increases. The more times it rains, the more serious the deformation is, and even the roof collapses. Second, the roof with mineral wool has the function of absorbing water. On rainy days, all the rainwater leaked from the roof gathers in mineral wool, which increases the weight. Third, when the roof is hot in summer, the sudden rainstorm makes the temperature of the color plate drop sharply, and the color plate shrinks rapidly, resulting in the deformation of the color plate and the loosening of nails. 5. Water seepage at the foot of high-low span roof wall: cement splashes, sealant or waterproof coating are used for waterproof protection. When cement is not combined with metal, cracks will occur. When the elongation of paint or sealant is small, large cracks may appear. 6. Why does the weather-resistant sealant still seep out? The weather-resistant sealant will shrink after curing, and it may separate between the sealant and the frame when shrinking, which will be more serious if there is dust on the frame. The long-term high temperature of color steel roof accelerates the aging of weather-resistant adhesive, and the metal material expands with heat and contracts with cold for many times, and the weather-resistant adhesive soon fails. 7. Why did the waterproof paint leak after two years of repair? The fluidity of waterproof coating leads to uneven coating thickness during construction, and it is not easy to find cracks. Coupled with roof vibration, the coating elongation is low and cracks appear. Jerry-building in the construction of waterproof coating, the coating thickness is too thin, and it will soon age and crack.

Second, the governance plan:

Self-adhesive waterproofing membrane for metal roof is used to block all parts of color steel tile where water seepage may occur.

Surface material of self-adhesive waterproofing membrane: membrane structure: self-adhesive layer+polyester non-woven fabric+metal aluminum foil (note: the three are a whole product). Metal aluminum foil has the characteristics of sun protection and quick heat dissipation, and also protects the waterproof layer and prolongs the service life. The super-soft matrix cloth is added in the middle, which not only strengthens the tensile strength of the waterproof layer, but also firmly adheres to the roof with the ups and downs of the color plate, so that the color plate is completely isolated from the air, which has both waterproof function and anti-corrosion effect. Cold construction technology is adopted, which does not need open flame construction and does not damage the paint of the color plate and the insulation under the color plate.

Third, the construction technology:

1: Full paving method: The color steel tile roofs are all paved with special waterproof coiled material for color steel tiles. It should be laid horizontally. The advantage of this is that it can achieve waterproof and anti-corrosion effect on the roof, especially on the nail holes on the roof, because most nail holes begin to seep after three years. Solve the problem once and for all, no worries.

2: For seams only, it is best to do it twice. The bottom is 33 cm, and the top is 50 cm wide. The eaves should be wrapped twice.

3. Waterproof base operating conditions:

3. 1. The base surface of the color steel tile is free of dust and looseness. Loose parts can only be constructed after treatment.

3.2, the base surface can not have water phenomenon, if any, it must be reinforced, and the waterproof layer construction can be carried out only after it is qualified.

3.3. When the gap of the color steel tile exceeds 0.3 mm, it should be reinforced and treated before construction.

3.4, Yin and Yang Angle, elevation pile and plane Yin Angle, elevation inside and outside Angle must do additional layer.

3.5, construction in the morning, color steel tile surface dew, stop construction.

3.6, winter construction color steel tile to brush the basic treatment agent.

4. Operation process:

4. 1. Cleaning the base surface: wipe off the dust on the surface of the old color steel tile with a mop, and if there is rust, remove it to make it smooth and clean.

4.2. Make additional layers: make additional layers at the corners of yin and yang, vents, gutters, etc. Additional layer 15cm-30cm wide, extending along the central axis of Yin and Yang angle.

4.3. Large-scale construction: a. Play the baseline first to make the pasted coil neat and beautiful.

B. Tile the coiled material, align it with the site to be constructed, and roll it up from both sides.

C. Cut the release paper from the top, peel off the release paper, and squeeze the coil to make it as flat as possible.

4.4. Requirements:

A. When laying coiled material, it should be laid in the downhill direction of running water during construction. This straight wall is lowered from a height.

B, air is excluded, and the air in the coil is squeezed out with the rolling pressure of the coil, so that the coil is firmly bonded.

C when the temperature is low, the base and the coil must be coated with the base treatment agent at the same time.

The overlapping length of D coil is 3cm-8cm, and the short length is 10cm.

E. Short-side overlapping of exposed coil, coil sealing head and heterosexual parts shall be sealed with sealant. In principle, the end of the coil vertical wall is fixed in the reserved groove with metal battens, and then sealed with sealing paste.

Fourth, the construction matters needing attention:

1: The old roof requires dust-free, as long as it is clean. The old roof can be scrubbed with a mop, and it is not easy to be too thick if the treatment agent is brushed.

2: The optimum thickness is 1.5MM or 2 mm, and the southern carcass is the best choice.

3. When constructing matrix-free materials, it is best not to construct in foggy days or just after the heavy rain stops, because moisture will generate bubbles.

4: The long side and short side of the coil should overlap not less than 10cm.

5: The lap joint between coil and coil, coil and strengthening layer must be firm, and there can be no edge warping. Conditional projects should be tested for water retention.

6. Don't just uncover the waterproof layer after construction, because the longer this material is bonded, the stronger it will be. If it is uncovered for more than two times, there will be a phenomenon of weak bonding, and it is necessary to coat the grass-roots treatment agent to completely bond.
