Is it necessary to make a drip line in the interior of the building?
(C) drip line practice
In the construction, some parts such as: parapet small edge, vents cover, or highlight the wall and other parts of the wall, these parts of the general along the water, the slope is not less than 1: 6, the mouth is usually used drip Line (commonly known as olecranon) approach (the body parts should refer to the construction drawings or consultation with the design unit). Drip line construction should be completed with the wall plaster, highlight the bottom of at least 10mm. Request to be consistent, round around. The practice is as follows:
1, the grass-roots treatment: the remaining mortar, dirt, dust clean, wet with water, "thrown hair" or "chisel hair."
2, hanging vertical, looking for the level: the corner should be hanging vertical, the bottom should be in the same level, these parts should be ahead of the ink line or pull line control.
3, the construction should be completed before and the bottom of the plastering, and then the ruler caught in the wipe on the bottom of the board, feet slope outward, with a good level to play a good level to make it in the same level, and around Circle, and then complete the side plaster, so that the bottom of the formation of the shape of the "olecranon" drip line.
4, remove the ruler, and then drip line pressure, straight, to ensure the quality of perception.
5, the drip line can also be made in the construction of the structure, in the daughter of the small wall along the mold, with ф50 shelf tube bottom mold, the mouth with a wooden pad flat, the outer mouth of the tube itself with the shape of pouring into a "eagle Mouth ", after demolding and then plastering dressing.
(B) structural construction, leaving a drip line (groove)
In the whole cast-in project, it is advisable to set aside the dripping line (groove) in the construction of the structure. The concrete method is to set the position of the drip line (groove) in the structure construction stage. Hole pouring together, the operation should pay attention to the following:
1, in the template design, should calculate the size of the drip line (slot), so that the drip line (groove) up and down neatly consistent.
2, drip line (groove) thickness calculation is also very important, can not reduce the thickness of the protective layer of steel, can not "eat" into the window hole.
3, hole template installation in place when personnel should be careful, the location of the hole template, the elevation should be accurate. There are reliable fixes.
4, do the protection of finished products, especially in the early demolition of the mold, the concrete strength is low, we must do a good job in protection, so as not to late decoration, drip line (groove) damage too much, affecting the quality of decoration.
