[China Aluminum Industry Net] Outer sliding aluminum alloy doors and windows and aluminum alloy curtain wall hardware should be preferred sliding support, sliding support is the use of the principle of variable area under the conditions of the same side length of the quadrilateral to achieve the purpose of opening aluminum doors and windows. The sliding braces are fixed in the hardware space of aluminum alloy door and window sashes and aluminum alloy door and window frames. When the aluminum alloy doors and windows are closed, they are completely hidden in the aluminum alloy door and window sash and the aluminum alloy door and window frame to solve the problem of exposed hinges. When aluminum alloy doors and windows are equipped with sliding support, the following matters should be noted: kaiping aida sanitary ware technology co.,ltd , https://www.kpfaucets.com
1. When using sliding support, according to the weight of aluminum alloy door and window sash, external dimensions and the space dimensions of the hardware, choose a sufficient strength of the sliding support, and ensure that the sliding support and the aluminum alloy door and window frame and fan reliable connection. The bearing weight of the sliding support should be greater than or equal to the weight of the aluminum alloy door and window fan.
2. The sliding support of aluminum alloy doors and windows with outer flat-opening is mainly subjected to shear force, while the sliding-support of upper-hanging aluminum alloy doors and windows is mainly subjected to axial force, and the two kinds of sliding stays cannot be mixed.
3. Open aluminum alloy doors and windows open a larger angle, requiring sliding support flat motion stroke longer, the general slid length to reach aluminum doors and windows wide 1/2 to 1/3.
4. Determine the height of the lock point and the type of the lock block and the number of lock points based on the amount of overlap, profile hardware space, and structural dimensions.
