Determine the key waterproof areas before construction
The following area of the color steel tile roof needs to do key waterproof treatment: horizontal lap, vertical lap, roof ridge, sink, color steel tile and parapet junction, screw firmware, color steel tile connection gap and so on for the color steel roof waterproof weak links.
Pretrement
Carefully check the color steel roof before construction,determine that the metal roof is firm, clean, no corrosion, no freezing and water ze, do not conform to the above situation is treated as follows;
1、Add the firmware in place.
2、Using polishing machine wire grinding wheel or sandpaper grind the loosen rust area,Wash with pressure water cannon,Clean up the surface then wait surface dry enough,now the surface is free of rust and dust,Remember, we must ensure that the surface is clean and not dirty, otherwise it will affect the construction effect of self-adhesive coil.
3、Remove freezing, dust , wipe clean with water, keep the surface clean and dry.
Construction operation
Preparation before construction
Before the construction, the workers first put on safety hats, tie the safety rope, wear good anti-skid Shoes, safety measures in place and then fixed the safety rope at both ends of the color steel tile, fixed the safety rope on the main rope, and check whether the safety rope joint is firm, and check the bearing situation of the color steel tile.
Fix the scaffolding on both sides of the color steel tile eaves, and confirm whether it is firm and firm Solid rear can stand people.
In order to ensure the safety of the construction personnel transported to the roof, it is necessary to be lifted The handlebar coil is safely hoisted to the roof.
1、When paving the coil, the construction from the water downhill direction(Roof parts)Start paving.The vertical wall is paved from the height to the bottom.
2、Eliminate the air, squeeze the air with the coil rolling, and compaction, so that the coil firmly bond.
Exposed edge and overlap edge should be used with 5cm butyl tape sealed, Standing wall The header was sealed with 10cm butyl tape.
Safe construction measures
1、Before the construction, the workers first fixed the safety rope at both ends of the color steel tile, fixed the safety rope on the main rope, and check whether the safety rope joint is firm, and check the bearing situation of the color steel tile.
2.Workers before construction first put on safety hats, tie the safety rope, wear good anti-skid Shoes, safety measures in place before the construction.
3、Fix the scaffolding on both sides of the color steel tile eaves, and confirm whether it is firm and firm Solid rear can stand people.
4、In order to ensure the safety of the construction personnel transported to the roof, it is necessary to be lifted The handlebar coil is safely hoisted to the roof.
Construction instructions and reminders
1、Clean the surface of the adhesive material before use to ensure that the surface is dry and clean.
2、It is recommended to do waterproof in the water surface construction, and the sand base surface is not recommended to use.
3、Tear off the product isolation film, direct adhesion, do not need to fire baking.
4 、When sticking, ensure close adhesion, avoid cracks, bubbles, etc., to ensure the use effect.
5 、Before the construction, the quality of the previous project shall be accepted, and the waterproof layer construction shall be carried out after the qualification.
