(3) Window should be consistent with the seal <"Architecture doors and windows sealed strips>> JG / T 187 requirements. (4) the main glass doors and windows with single glass, insulating glass and laminated glass. Single glass thickness 3mm, 5mm, 6mm, 8mm; laminated glass thickness of 4mm +4 mm, 5mm +5 mm, 6mm +6 mm; insulating glass thickness of 4mm + A +4 mm, 5mm + A +5 mm, 6mm + A +6 mm (A = 6mm, 9mm, 12mm, 15mm). glass installation should comply with <"Architecture Technical Specification for Glass Applications>> 7G7 113 requirements. When using coated glass, coated glass should be installed in the outer layer of glass, one side should be toward the interior coating layer (5). The mechanical properties of windows and doors should be consistent with <<unplasticized polyvinyl chloride (PVC-U) Plastic Door>> JG / T 180 and "<unplasticized polyvinyl chloride (PVC-U) plastic windows>> 7G / T 140's requirements. (6) windows surface should be smooth, no bubbles and cracks, door frames should be obvious decorative surface damage, in -40 �� ~ -70 �� ambient temperature under normal use. Application of color and color co-extruded film and other advanced surface decoration technology, and highly decorative. (7) windows component by <"Architecture mine design>> GB 50057 (2000 edition) provides lightning protection system with the main structure of the connection. (8) windows and doors should be consistent with the size of allowable deviation <<unplasticized polyvinyl chloride (PVC-U) Plastic Door>> JG / T 180 and "<unplasticized polyvinyl chloride ((PVC-U) plastic windows>> JG / T 140 requirements.

Second, the installation process
Portal size clean-up check on the fixed parts �� �� loaded plastic door and window openings will be the temporary correction of fixed �� �� fixed.

Third, the common problems and prevention measures
1. The overall stiffness of the door frame difference
(1) phenomenon: the push-pull or open and close doors and windows, or encountered strong wind, the door window frame shaking.

(2) reasons: �� profile inappropriate choice of cross section of small, strength is not enough. Aluminum windows and doors to prevent the material does not meet the requirements. Steel doors and inferior quality materials. �� plastic lined steel doors and windows configuration does not meet the standard, (usually steel liners use 1.20, but because the owners do not see the install up. a lot of business to the owner failed to use the installation) of steel thin-walled, intensity difference; lined steel section inserted, do not form a whole to strengthen the role; lined with steel and plastic profiles connection is not strong, etc.. �� specification fails to install the node. �� Depending on the wall without using different fixation methods.

(3) measures: �� door window frame profile specification, the number in line with national standards. Aluminum profiles of the frame wall thickness of not less than 2.4 mm. PVC window material thickness of not less than 2.5 mm. �� Check the appearance of plastic profiles, profiles should be qualified for the green white or ivory white, clean and smooth. protective film should be good quality. �� hole under the window size, select the installation height profile cross section, not less than 55 series casement window, sliding window is not less than 75 series. �� installed strictly according to specification, to ensure solid stability.

2. Windows leak
(1) phenomenon: �� the wall around the door frame and junction leakage. �� push-pull down water tank and into the window.

(2) reasons: �� door window frame and the wall with cement mortar caulking. �� door window frame and the wall between the plastic injection lax, there are gaps. �� process failed windows, window frames and sashes with strictly between. �� sash installation of seal failure, water from the cracks into the glass sash. �� out of the window frame without drainage holes.

(3) measures: �� door window frame and the wall with cement mortar shall not be caulking. Should be flexible connections, sealing filling them with sealant, can not have gaps. �� Check windows and doors before installation, if qualified, window frames and sashes are strictly between the combined , window seal installation eligibility. �� 50 mm frame and the hole left over the gap, so that water can sill slope. �� orbital frame should be under the box and drill drainage holes.

3. Windows color significantly. (1) phenomenon: the adjacent door or window frame color is inconsistent with the fans. (2) reasons: the same plant material non-product, or with a group of products, or different material grades of products. (3) measures : �� profiles should be used to buy the same product manufacturers, and an ample supply of feed. �� attention to ingredients before cutting the color, to avoid the color of materials used in the same large doors and windows.

Fourth, quality problems installing doors and windows fan control measures
1. Window fan warping more than 2mm, not the factory use. (1) approach the doors and windows have been fans, stacked neatly according to size, solid flat pad to pad when the flat bottom, from the ground to have a gap for ventilation . (2) fan before installation to check on the doors and windows, warped more than 2mm, can be used after disposal.

2. Doors open fan is not working. (1) fan test box should be checked before the legislature is quite vertical. To ensure that hinges out, the same depth, so that the upper and lower hinge axis maintained in a vertical line. (2) selection hardware to support, screws must be straight. (3) installation of door and window fans, the fans and the fans, box fans and the gap between the right to stay.

3. Window fan switch itself. (1) installation of doors before checking whether the vertical door frame. (2) An hinge slot should be the location of the hinge line, the depth of the right upper and lower hinge axis in a vertical line.

4. Window fan side port is too large or too small. Repair plane, we should deliberately scratched partial mouth. The general control of 2-3 �� and consistent.

5. Window fan slot is uneven, not straight. (1) if direct repair is not sure when the plane, according to the requirements of the gap size, with a pencil along the inside edge of the box fan to draw in the plane's position should be revised. Repairable Be careful not to eat when the plane line, to leave room for some repairs. (2) Installation of fans, especially when the upper and lower windows on the fan should cut out the mouth first fan. cut mouth seam should be straight, strict, inside and outside consistent. hinge groove to the depth of the same tick, so have a good chance to crack down consistent.

6. Window fan to fall. (1) fan before installing doors and windows, to check the quality of the fan, the fan on the required well L-shaped, T-shaped angle iron. (2) to select the appropriate size of the hinge, use wood screws and hinge support. (3) installation, wood screws should be used to hammer into the 1 / 3 the depth, and then screwed into, not into the whole depth. (4) the amendment when the plane door and window fans, do not install hinge side bottom, it may dig around 1mm, so fans pick the head slightly, left to fall in the margin.

In addition to these quality problems installing doors and windows fan control measures, there are boxes and fan contact surface uneven, double spring door installation defect prevention and control measures.

Fifth, on-site management
1. Steel doors into the plant, it should be kept upright by the holder in the indoor set, and separated with a 1m or more heat sources, ambient temperature should be lower than 50 ��, not less than 70 �� vertical angle of plastic doors and windows Install on-site storage should not exceed two months, all stored at 0 �� environment, doors and windows, the installation should be at room temperature before 24 hours after installation. install windows and doors, their environmental temperature is not lower than 5 ��.

2. According to design drawings of plastic doors and windows, doors and windows of check and acceptance of variety, quantity, specifications, models, open direction, the combination of rod, accessories, and its shape and smoothness of inspection, and should check for open welding, fracture and other damage phenomenon, qualified only after installation.
