滴水線（drip line）

1、滴水線（drip line）drip lineeditIn the window below the table will generally have a concave line, that is to prevent rain delay plate flow to the design in the wall, in the line outside the rain fall, this is the drip line, applicable to the construction of water blocking requirements of the site, the ge

2、neral drip line (tank) in the window lintel under the mouth, if the concrete surface is very smooth with texturing on the surface.Catalog1 water line2 water practices3 Construction Technology4 drop rangePrinciple 5 water line1 water line editorIn the construction project in order to prevent the wate

3、r from the stream in the end wall and side wall vertical design, groove shaped parts along the lower part of the structure is arranged around the drip line, called (also called Gargoyle). General settings in the awning, windows, stairs, balcony, parapet wall and top prominent waist and other parts.T

4、he general is at the junction of the bottom surface of the outer wall of the place, from the corner of 1-2cm, do a groove about 1cm wide, so the water can be cut off without inward flow.2 drop editing practice1, basic level processing: General drip line (tank) in the window lintel under the mouth, i

5、f the concrete surface is very smooth with texturing the surface: one is chisel, namely with chisel cutting, tick to smooth the rough. Another method is to scorch, which is on the surface of the concrete clean up by mechanical spraying or with a broom thrown on a layer of cement mortar (1:1 gruel sh

6、ape with appropriate building glue) to dissolve in the concrete surface, with the hand not moving.2, paste the drip line (tank): according to the elastic line of position well, by adding the adhesive mortar to the drip line (tank) paste, depending on the situation, about 50 80cm cloth a paste, less

7、than 2m in 2 3 point window cloth, more than 2m of 3 5 point window cloth.3, the drip line (tank) construction should be carried out simultaneously with the construction of outer wall plastering plastering, when to window or balcony at the bottom, to complete the hole outside wall and then turn the

8、ruler plate, the ruler plate clamped has a good wipe Great Wall, the ruler plate groove inwards, and bottom line the first thing is stuck the drip line (tank) for level, and then wipe the windows.4, such as the introduction of the drip line (tank) (usually outside the window head), bottom ash has be

9、en put to the window, such as the use of steel, wood window, the window can be tight sealing, such as the use of Aluminum Alloy or plastic windows in the window should be left around 5mm groove, so as to do plugging sealant; highlight the bottom opening of the drip line (tank) (usually in the balcon

10、y or the rain cover at the bottom), in the bottom ash on a wide mouth to float (8 to 10cm), about 5cm from the external wall inward position than the ruler plate trimming, then iron float pressure light, inside the small angle with Yang Yang angle sub straight, light pressure lutetium lutetium.5, wa

11、ter treatment: to prevent dripping urine wall, the drip line (tank) not to be in the wall, away from the wall where 5cm is truncated, so that water is not flowing into the window (balcony), and can not flow to the wall.In 6, at the bottom of plastering reaches a certain intensity (after final settin

12、g), with a small knife or a wet towel to clean the mortar tank. Note that in the facet processing groove, groove edges should be maintained, can not be put into the arc-shaped hook.(two) construction, set aside the drip line (tank)In the full cast project,To promote the structure of the construction

13、 set aside the drip line (tank), the specific approach is: the setting hole template in the construction stage, calculate the drip line (slot) and the position of the drip line (slot) and the windows and doors be pouring, operation should pay attention to the following points:1, in the template desi

14、gn, should calculate the drip line (tank) the size of the position, the drip line (slot) on the same.2, the drip line (groove) thickness calculation is also very important, not only can reduce the thickness of concrete cover, can not eat into the window.3, the template installation personnel to oper

15、ate carefully, the position and elevation the template to be accurate. Reliable fixing measures.4, good product protection, especially in the removal of the early strength of concrete is low, must do good protection work, so as not to post renovation, drip line (slot) too much damage, affect the qua

16、lity of the decoration.(three) the drip line approachIn the process of construction, some parts such as: small, flat vents along the parapet, or prominent wall waist and other parts, these parts along the slope usually do flashing, not less than 1:6, and usually use the drip line (commonly known as

17、olecranon approach (the body) should refer to the construction drawings and design units or consultation). The construction of the drip line shall be completed at the same time with the wall plastering, highlighting the bottom surface of at least 10mm. Be straight, turn around the circle. The practi

18、ce is as follows:1, basic treatment: the remnants of the mortar, dirt, dust cleaning, water wetting, scorch or chisel.2, hanging vertical, finding level: the corner part should be hanging vertical, at the end of the mouth should be at the same level, these parts should advance play Moxian or pull li

19、ne control.The above should be completed and the bottom 3, plastering construction, and then the ruler plate clamped with the bottom surface of the ruler plate, the groove outward, with good looking for the play prior level level, which is at the same level, and the periphery, and then complete the

20、side at the bottom of the formation of such plastering. The shape of chick dripping line.4, remove the ruler plate, and then the drip line pressure light, run straight, ensure the appearance quality.5, the drip line can make the structure of the construction, the parapet formwork along the small, do

21、 die at the end of 50 with Phi tubes, in the mouth with a wood pad, outside the mouth using tubes pouring into the chick shape itself, after the removal of plaster dressingThe 3 Construction TechnologyA, construction preparation1, plastering should be checked before window frame is in the right posi

22、tion, and is firmly connected to the wall.2, the wall beam, the surface of the substrate of the dust and dirt, grease should be cleaned, and water.3, check before plastering scaffolding outside, to ensure the safety of construction, will pull loose node timely recovery.4, advance the inspector door

23、and window opening, parapet capping and other parts of the serious lack of angle off the edge or plastering thick part should be early treatment, to prevent a thick plaster.5, the first prototype, identified after the organization construction.Two, material requirements (drawings according to the co

24、nstruction requirements of general use):1: 32.5 and above, cement slag or ordinary cement, consistent color, should be used in the same batch.2, sand: the sand, the average particle size of 0.35-0.5 mm,The sand cleaning requirements shall not contain clay, grass, and other organic harmful substances

25、. Sand to 5 mm aperture sieve before use.Three quality requirements:1, to ensure the quality of all materials, between the plaster layer and base to firm adhesion, no delamination, hollowing, cracks and dust explosion.2, smooth and clean surface, uniform color, with no lines, line angle, gray line s

26、traight founder, clear and beautiful.3, window, frame and wall filling density, hole, groove, box size is correct, neat, smooth, square.4, the drip line should be neat and straight, width and depth shall be not less than 10 mm.Three, process:Surface cleaning, elastic line, paste water groove to clam

27、p ruler plate to a light pressure, distillation, plastering, curing and finished dressing angle.Four, the drip line approach:1, in the process of construction, some parts such as: small, flat or vents along the parapet wall prominent waist and other parts, these parts along the slope usually do flas

28、hing, not less than 1:6, and usually use the drip line, commonly known as the olecranon. The construction and plastering the drip line at the same time, highlighting the wall at least 10 mm. Be straight, turn around the circle.2, basic approach: General drip line in the window lintel under the mouth

29、, if the concrete surface should be very smooth, texturing, a chisel, another method is to scorch. Scorch is 1:1 gruel shape cement mortar mixing proper amount of adhesive and solidification in the concrete surface, with the hand not moving.3, hanging vertical, finding level: the corner part should

30、be hanging vertical, at the end of the mouth should be at the same level, this part should be ahead of time bomb line or pull line control.Five, product protection:1, pay attention to the protection of plastering windows, drying racks and other facilities, the window frame on the residual mortar tim

31、ely treatment.2, over the shelf to be careful, be careful not to touch the broken wall and has a good wipe drip line.3, pay attention to the maintenance of plastering, should prevent the surface of the sun, water, impact, to ensure that the ash layer has enough strength.Six, matters needing attentio

32、n and explanation:1, hollowing and cracking due to the drip line plastering is small and narrow, easy to crack, so the primary treatment should pay particular attention to, plastering before pouring enough water, thick plastering should be stratified, each layer should not be too thick.2, the window ate the same layer window under the mouth is not at the same level, is d
