Energy-saving doors and windows project quality problems and prevention and control measures?

What are the quality problems of energy-saving doors and windows project and the prevention and control measures? The following Zhongda consulting for you in detail.

1, aluminum alloy doors and windows material failure

Prevention and control measures: ① design unit should be based on the use of functional, regional climatic characteristics to determine the strength of wind pressure, air infiltration, rain infiltration performance index, the selection of the appropriate set of code and pattern specifications. ② the use of aluminum alloy profiles should be carried out beforehand profile thickness, oxide film thickness and hardness test, qualified before use.

2, aluminum alloy doors and windows incorrectly

Prevention measures: ① Before installing aluminum alloy doors and windows frame, according to the design requirements, should be popped up in the opening on the opening pop-up opening on the opening of the installation line, according to the line of the opening. ② in the aluminum alloy door and window frames before the formal anchoring, should check whether the door and window vertical, such as problems should be corrected in a timely manner before the formal anchoring with the opening.

3, anchoring practices do not meet the requirements

Prevention measures: ① aluminum alloy doors and windows selected anchors, in addition to stainless steel, should be galvanized, chrome-plated, nickel-plated methods of corrosion treatment. ② anchor plate should be fixed firmly, there shall be no loose phenomenon, anchor plate spacing should not be greater than 600mm anchor plate from the frame corner should not be greater than 180mm. ③ anchor on the brick wall, the impact drill should be used to drill holes in the wall, stuffed with a diameter of not less than 8mm metal or plastic expansion tube, and then screwed into the wood screws for fixing.

4, aluminum alloy door and window frames and the opening wall is not flexible connection

Prevention measures: ① aluminum alloy door and window frames and the opening wall should be used between the flexible connection. The gap can be filled with mineral wool strips or glass wool felt strips in layers, the gap surface to leave 5-8mm deep groove, with sealing materials inlay, sealing. ② in the construction process shall not damage the aluminum alloy doors and windows on the protective film, such as surface stained cement mortar, should be wiped clean at any time.

5, aluminum alloy window sash push and pull inflexible

Prevention measures: ① In the window frame around the gap with the opening wall using a flexible connection to prevent the aluminum alloy window frame deformation by extrusion. ② selection of good quality, and with the window matching the pulley.

6, aluminum alloy sliding window fan derailment, falling

Prevention measures: ① the production of aluminum alloy sliding window sash, should be based on the height of the window frame dimensions, determine the height of the sash, not only to ensure that the sash can be installed into the window frame, but also to ensure that the sash in the sash on the frame of the sash has enough embedded depth. ② To choose the thickness of the aluminum profile in line with the design requirements.

7, aluminum window leakage

Prevention measures: ① in the window lintel for the drip groove, drip line; in the window sill to make the outward flow of water Yu slope, the slope is not less than 10%. ② mineral wool felt strips and other aluminum alloy window frames and the gap between the wall of the opening to fill solid, and then outside with high-quality sealing materials sealed tight. ③ of aluminum alloy window frame mortise and tenon joints, riveting, slide braces, square grooves, screws and other parts of the application of waterproof glass silica gel sealing tight.

8, glass cracking, shortage, fall off

Prevention measures: ① Aluminum doors, windows, the use of glass to use good elasticity, aging-resistant high-quality glass tape. ② glass glue strip to leave a 2% margin when the material, as the glue strip shrinkage reserves. ③ square, rectangular door and window glass fan with adhesive tape, to be cut off at the corners at 45 °, butt. ④ Before installing the glass adhesive strip, the groove should be cleaned up first to avoid foreign matter in the groove. ⑤ Before installing the glass glue strip, inject the glass glue evenly within 20mm of the end of the corners of the glass groove.

9, aluminum alloy doors and windows do not glue

Prevention measures: aluminum alloy doors and windows, regardless of the connection method, should be in the joints of the gap with waterproof glass silica gel inlay, sealing, in order to prevent rainwater seepage along the seams of the interior.
