Seepage water treatment outside the window and Treatment

 Drenching rain test simulates the way, take the external doors and windows have water pressure water spray test. Every 4-6 layer is provided with a lateral water spray, spray test period of not less than six hours. When watering, horizontal tubes should be arranged in all the walls, in order to check the wall leakage risks. When do temporary water spray test, should ensure temporary water poured over water and water pressure continued watering times meet the test requirements, and to ensure that water flow on the bottom of the wall to meet the test requirements. Should choose PPR tubes made of a material with good rigidity and poured water pipe fittings, water pipe water spray layer on layer of indoor and outdoor window or from the roof leads to a temporary water tank, and make effective and guarantee a fixed shower water is not deformed. Shower pipe diameter is preferably 20-25mm, distance from the window surface is preferably 100-150mm, evenly distributed linearly blowhole, spray direction and the horizontal angle should be about 30 degrees -45 degrees, diameter 2-3mm, Hole spacing 150-200mm, water is under the greatest amount of water or normal water pressure booster pump pressurized water use, to ensure that the outer surface of the window to form a water curtain.

 

After tricking field engineers outside the window into the family regularly inspect visually observed outside the window and the surrounding for leakage. Found that leakage of water, dampness, water phenomenon printing area to do eye-catching mark, identify leakage reason, make a detailed written records, and further arrange rectification review. After meta-analysis, the external walls of water leakage prevention should focus on the following aspects of governance:

Reason 1: Peripheral filling without making the concrete wall at the bottom of the anti-sill or three skin solid brick masonry;

Preventive measures: the bottom part of the wall outside the window set up three skins bricks

Preventive measures: the bottom part of the wall outside the window sill set concrete anti-

Reason 2: Exterior scaffolding eye,I_beam girder reserved Tunnel Closure rough, is not standardized;

Precautions: external window to pull the screw parts of the use of cement mortar after plugging brushing JS waterproof coating

Precautions: Use fine aggregate concrete block exterior wall reserved for expansion openings and scaffold eye

Reason 3: 6CM without making concrete the upper sill top pressure, but the use of solid small brick building;

Precautions: 60mm thick outer window site pouring concrete pressure

 

Reason 4: The sides 150mm high aluminum window frames and sill unused cement mortar / concrete plug seam. The presence of the bottom sash with a big wedge fixed, small bricks, styrofoam; 150mm high Cypriot side seam failure; shut between the window frame and the wall is not in place, the rough, the large gap;

Preventive measures: between aluminum window frames and the wall plug cement mortar joints in place, shut appearance

 

 

Reason 5: glue round the window is not in place, sealants rough uneven peeling;

Precautions: aluminum window frames four weeks gluing dense, straight appearance

 

 

Cause 6: along the window without making the olecranon / drip line or down slope phenomenon exists; windowsill not find the slope or down slope phenomenon exists;

Preventive measures: the window eaves drip line / olecranon production place

Preventive measures: the slope sill set out, in line drawings, smooth drainage

 

 

Reason 7: a large gap between the aluminum window frame profiles, the bottom of the box without scuppers, profile patchwork site is not tight, the large gap;

Precautions: aluminum window frame profiles patchwork tight set scuppers

 

 

Reason 8: the south slope of singl_conditioned board without looking and without making waterproof layer; air_conditioned double_board memory in the water phenomenon, did not find the slope, shutters bottom without making scuppers.

Precautions: single_conditioned board waterproof construction to find the slope in place, no water. Before making a waterproof protective layer of mortar to find the slope

Precautions: venetian bottom frame indwelling scuppers, no water inside the air_conditioned double plate. Before making a waterproof protective layer of mortar to find the slope
