[China Aluminum Industry Network] Treatment measures for aluminum alloys, plastic doors and windows:
(1) The installation of windows and doors must be in accordance with the installation procedure. Check and adjust the installation quality of each procedure at any time. (2) The window frame and the window hole must have a center line. When the window frame is installed in the hole, the center line should be aligned. The frame corner should be temporarily fixed. Carefully adjust the vertical, horizontal and vertical angles of the window frame. The error should be within the allowable deviation. . (3) The deviation of the diagonal line and flatness shall be checked before the door and window fan enters the frame. The lap width and peripheral gap of the frame fan shall be checked with a steel ruler and a feeler gauge after the frame, until the requirements are met. (4) Correctly install hardware parts and find that damage should be promptly replaced. (5) Do a good job of product protection and normal use and maintenance to prevent external impact, not hanging heavy objects, resulting in deformation of doors and windows. Use lightly to turn it off and extend its service life.
Aluminum alloy and plastic door and window switches are not flexible. Analysis of the causes of lax shut-off If there is a blocking phenomenon when opening and closing doors and windows, the switch needs a lot of effort. When the frame fan has a small lap width and the surrounding gap is uneven, it is generally caused by the following Several factors contribute to:
(1) The window frame or fan is deformed, and the sealing strip looses and falls off.
(2) Damage to hardware accessories.
(3) The installation quality is poor, exceeding the allowable deviation, and it has not been adjusted in time.
Prevention:
(1) The installation of windows and doors must be in accordance with the installation procedure. Check and adjust the installation quality of each procedure at any time.
(2) The window frame and the window hole must have a center line. When the window frame is installed in the hole, the center line should be aligned. The frame corner should be temporarily fixed. Carefully adjust the vertical, horizontal and vertical angles of the window frame. The error should be within the allowable deviation. .
(3) The deviation of the diagonal line and flatness shall be checked before the door and window fan enters the frame. The lap width and peripheral gap of the frame fan shall be checked with a steel ruler and a feeler gauge after the frame, until the requirements are met.
(4) Correctly install hardware parts and find that damage should be promptly replaced.
(5) Do a good job of product protection and normal use and maintenance to prevent external impact, not hanging heavy objects, resulting in deformation of doors and windows. Use lightly to turn it off and extend its service life.
Reasons for the damage of plastic door and window hardware fittings and prevention measures The general performance of plastic door and window hardware fittings is as follows: The hardware fittings are not firmly fixed, loose and fall off, and the pulleys, sliding hinges, etc. are damaged, and the opening and closing are not flexible.
Causes of hardware damage:
Improper selection of hardware accessories, poor quality; metal liners are not set when tightening, there is not enough installation strength.
Measures to prevent damage to hardware:
(1) The type, specification and performance of the selected hardware accessories shall comply with the current national standards and relevant regulations and be matched with the selected plastic doors and windows.
(2) For sliding windows with a width of more than 1m, or with double glass doors and windows, double pulleys or rolling pulleys should be used.
(3) Sliding hinges shall not be made of aluminum alloy material. Stainless steel (4) shall be used to install hardware with fastening screws. Metal liners shall be provided. The thickness of the liner shall be at least two times greater than the fastener pitch. Do not fasten on plastic profiles or use non-metallic linings.
(5) Hardware fittings should be installed later. Door and window locks, handles, etc. should be assembled after the window leaf is inserted into the frame to ensure correct position and flexible switching.
(6) After the hardware is installed, pay attention to maintenance to prevent rust corrosion. In daily use, you must lightly open and close the door to prevent hard opening and closing and damage.
Why in the kitchen, bathroom and other rooms, the lower part of the dividing wall is damaged by dampness. Although the tiles on the wall of the kitchen and the bathroom are tiled and marble and other decorative tiles (boards), the other side of the wall is a protective wall. Plates or wallpapers, paints, etc., but some of the walls will be used for a period of time after the lower tiles, marble will empty drums, and even fall off, wall protection panels, wallpaper, moldy black, paint desquamation mildew and so on. The above situation is due to the dampness of the wall surface.
In daily life, kitchens and bathrooms are often used for water, and the ground is prone to dampness. In particular, due to bathing and other reasons, the toilet floor is more likely to be exposed to water. If the level of floor drains does not meet the requirements, water will accumulate on the ground. If the partition wall, especially the cover plate of the lightweight partition wall, hits the ground, the cover panel will easily absorb the water on the ground, and it will swell, and it will bulge the tiles and marbles and even fall off. Because the cover panel is always in a wet state, The surface of the siding, wallpaper and paint will be mildewed and peeled due to moisture.
To avoid this from happening, do not touch the baseboard directly at the bottom of the panel during construction. The “Construction Ground Engineering Construction and Acceptance Code†(GBSOZO9-95) stipulates that isolation barriers shall be provided in toilets and architectural floors with waterproof requirements, edge beams shall be provided around the perimeter, and the height shall not be less than 12Omm and the width shall not be less than 10Omm. However, due to the construction of houses prior to the revision of this code, there is basically no such measure. Therefore, in the renovation of this type of house, a concrete guide wall (edge ​​beam) or a three-leaf solid brick shall be added at the place where the bathroom needs to be separated. When the cover panel is fixed, a gap should be left between the cover panel and the guide wall to prevent the cover panel from being damaged due to the capillary phenomenon and damp the wall surface.
Glass installation is not facing right. What to do? In recent years, more and more home-improvement use of coated glass, embossed glass, frosted glass as a special decoration materials, but sometimes the installation does not follow the direction of construction, affect Light reflections and decorative effects. In order to prevent this phenomenon, in addition to improving the technical level of the installers, corresponding control measures should also be taken:
(1) Pay attention to the orientation of the glass installation. When embossed glass and frosted glass are installed, the pattern of the embossed glass shall be directed outdoors, and the frosted surface of the frosted glass shall be directed indoors.
(2) The coated glass should be installed in the outer layer, and the coated layer of single-side coated glass should face the room.
(3) When cutting the glass, no nicks or splays must appear on the edge. When cutting the embossed glass and stained glass, the pattern should be the same and the seams should be consistent.
(4) Be careful not to clean the glass coating with an acid detergent.
The gap between the glass and the door and window sash is not sufficient. Some construction teams sloppy operations. When the glass is installed, the spacers or glass blanks are not set to the required size, and the pads cannot be placed so that the glass directly contacts the glass tank. Uneven gaps, glass weight can not be well supported, in severe cases caused by window fan deformation.
Prevention:
(1) Install glass spacers as required so that the weight of the glass can be supported to avoid deformation of the window sash. The glass mounted in the mullion should have two weight-bearing pads underneath, and the distance from the vertical edge of the glass to the resting edge is 1/4 of the glass width and not less than 150 mm. The other direction should be set bit block, in order to fix the glass to ensure evenly around the gap.
(2) The glass spacer should use hard rubber with a hardness of 80 degrees Nah, the width of which should be greater than the thickness of the supported glass, the length of not less than 25mm, the thickness is generally 2 ~ 6mm.
(3) Before the glass is in place, the position of the spacer should be checked to prevent the spacer from falling off due to impact and vibration. The position is inaccurate and the drainage hole is blocked.
(4) Strictly control the cutting size of the glass. The difference between the size of the glass and the size of the frame fan should be equal to the thickness of the two pads. The installation of glass is loose, the installation of the rubber seal off the glass is not centered, the gap of the glass frame is uneven, the rubber seal is not close to the glass and the window frame, and the installation is not smooth. Hit the glass with your hand and let loose. The reason for this situation:
(1) When installing the glass, the debris in the notch is not removed in time, so that the glass and the notch are not aligned.
(2) The gap between the glass and the glass notch is uneven, the rubber strip is in poor contact with the glass and the glass notch, and the glass notch protrudes, and the seal can be easily pulled off by hand.
(3) The rubber strip is not disconnected at the corner and is not glued.
The measures for rectification are:
(1)Before installing the glass, carefully remove the debris in the slot, such as mortar, brick, wooden block, etc., and carefully center the glass when it is placed to ensure that the gap on both sides is even and fixed in time to prevent collision displacement. Deviation from the center of the slot.
(2) The rubber seal cannot be pulled too tightly and the length of the blanking is 2O-3Omm longer than the assembly length. The installation should be in place, the surface is flat, close contact with the glass, glass notch, so that the glass around the force. The rubber strips should be cut off at the corners and glued firmly at the disconnection.
(3) When the glass is sealed by sealant, the glass should be squeezed with a rubber strip or a rubber block to leave gaps in the plastic injection. The depth of the plastic injection should not be less than 5mm. Before the adhesive is cured, the glass should be kept from vibration. .
Sliding window slide chute water accumulation, causing seepage how to do in order to uniform the facade of the building, the use of sliding windows is becoming more and more popular, but there are often water in the sliding window sliding chute, and the accumulation of water in the Under the action of wind pressure, it will infiltrate into the room, causing the water in the window tray to bring endless trouble to the user. The reason for this is that there is no drainage channel, or the drainage channel is blocked by debris, so that the water in the channel cannot be discharged smoothly.
To change the sliding window slot chute water, seepage method is:
(1) The drainage window must be provided on the sliding window of the outer wall. The distance between the drainage holes should be 600mm, and the number of doors and windows per mold should not be less than two. The size of the hole should ensure that the water in the tank is quickly discharged.
(2) The size of the drainage channel for plastic windows should be 4mm×35mm, and the corner should be 2O～14Omm. The holes should be staggered and the drain holes should avoid the cavity with reinforced steel.
(3) When installing glass or sealant, take care not to block the drain hole.
(4) Sliding window After installation, the mortar particles and trash should be removed from the tank and checked for irrigation. The water discharged from the tank can be discharged smoothly. Otherwise, it should be rectified until it is qualified. Aluminum alloy doors and windows leaking water in daily use will sometimes find that the aluminum alloy door and window frame around the wall with the junction of the leakage of water appears, in particular, the lower corner of the window is more common; followed by the joint window of the joint water seepage.
There are roughly two reasons for water seepage:
(1) Cracks are produced at the joint between the door and window frame and the wall body, and no sealant is used to fill and seal the installation. Rainwater seeps into the room from the crack.
(2) When assembling doors and windows, there is no sleeve connection or lap joint method, and no sealant seal is used.
