The roof, wall and other enclosure structures are generally made of color steel profiled plates with a thickness of 0.3-1.0mm. The color steel profiled plates are rolled by pre coated color steel plates such as galvanized (or aluminized zinc) and painted
on the surface. The advantages of single-layer color steel profiled plate are light weight, high strength, convenient production and installation, large workshop space and low price; the disadvantages are large thermal conductivity, large coefficient
of thermal expansion and contraction, poor sound insulation effect, and fast aging degree of spray paint exposed to ultraviolet radiation, which causes corrosion and rust of color steel plate due to rain erosion, leading to water leakage. For buildings
requiring insulation, heat insulation and sound insulation, double deck color steel plate and intermediate insulation materials, such as glass wool, rock wool, foam, etc., can be used.
The filling material can be filled in the field or pre compounded with the color steel plate factory (called color steel sandwich plate). The color steel sandwich panel has the advantages of filling material, high bonding strength with steel plate, good
overall performance, convenient installation and purlin saving, so it is widely used.
When using the products in the construction steps, the following steps shall be followed for the above A-side lapping, b-long lapping, c-ridge node, d-wall lapping,
e-drainage ditch lapping, g-anchor node and f-steel plate rusting:
Scheme I: 1 Remove the silicone rubber seal of the original protruding part to make the slab joints neat and the construction surface dry and clean; 2. First coat with adhesive paint,
then cover the painting surface with alkali resistant polyester cloth (60-80g), and then brush with waterproof adhesive paint; 3. Brush ice paint once again after drying for 2-3 hours, and then brush the second time after 3 hours; 4, if the gap between
the lap joints is greater than 5mm ~ 30mm, if you need to enhance adhesion, please add 1 layers of alkali resistant polyester fabric, and then rub third times of waterproofing paint over 3 hours. 5, the ridge tile of the ridge tile and the roof tile edge
plate can be filled with waterproof foam lacquer two times to prevent water seepage. 6. For rivets and self tapping nail holes, the waterproof adhesive paint can be directly applied to cover the nail holes four times with a thickness of about 1.5mm and
a diameter of about 50mm. The next time the above coating is applied, the coating will not stick to hands.
Scheme II: 1. Remove the silicone rubber seal of the original protruding part to make the slab joint neat, and the construction surface dry
and clean; 2. Paste the lap joint between the color steel plate and the color steel plate with the special waterproof tape of Taiwan color steel plate, which shall be tightly compacted, and then brush the waterproof adhesive paint for one or two times;
3, if the gap between lap joints is greater than 5mm ~ 30mm, if you need to strengthen adhesion, please add 1 layers of alkali resistant polyester cloth, then rub two times of waterproofing paint over 3 hours; 4, plug the ridge tile with the roof tile
edge plate and fill with the foam plug, then brush the waterproof paint two times to ensure that the water is permeated. 5. For rivets and self tapping rivet holes, the waterproof adhesive paint can be directly applied to cover the rivet holes four times
with a thickness of about 1.5mm and a diameter of about 50mm. The next time the above coating is applied, the coating will not stick to hands. It can also be pasted with special waterproof tape for color steel plate, and then brushed with a layer of waterproof
adhesive, with a thickness of about 1.5mm.
