Hardware accessories are the key components of plastic door and window structure, which is directly related to the performance and life of plastic doors and windows. When designing and selecting hardware accessories, it must have the function of accepting the sash's own weight and opening frequently, and also consider the safety, firmness, corrosion resistance and sealing performance when the sash is closed. The structure of the hardware fittings should be adapted to the structure and opening method of the plastic window. The most widely used opening methods for plastic windows are casement windows and sliding windows, and a few are flat and open windows. All the swinging, flipping, lifting and sliding windows are realized by different forms of hardware parts. Location and quantity of hardware accessories 1 Hinges: The number of plastic window hinges should be determined according to the size of the sash, the opening direction of the sash (inside opening and opening), the thickness of the glass and the number of layers, the wind conditions in the area where the window is used, the height of the building, etc. . 2 number of handles and linkage handles. The handle is usually placed in the middle of the window sash, about 1.5m away from the ground. When the sash height is <800mm, one handle is required; when the sash height is >800mm, two handles must be installed, and the position is at 1/4 of the upper and lower ends of the sash. However, the problem with the two handles is that when the window device is positioned at a high or large window sash, the short person can not reach the above handle, so the linkage handle should be used to achieve multi-point locking. 3 The window splicer (also known as the window sling) device should be positioned so that the sash opening angle is greater than 90° and the sash opening angle is greater than 60°. 4 push-pull window locks are recommended to be installed at the midpoint of the height of the push-pull fan. 5 Sliding window pulleys are installed at a position below the corner of the 100mm glass block. Each sash is equipped with at least two pulleys. Fixing hardware accessories The fixing of the plastic window hardware is different from the wooden window. Since the wooden window is a solid profile, the hardware is fixed by wood screws, and the riveting force is high. The plastic window is a cavity profile with a wall thickness of 23 mm. It is not necessary to use a self-tapping screw or a rivet using a general wood screw. In principle, the hardware components (hinge, support, etc.) must be fixed on the extracted reinforcing lining members. If there is no reinforcement, the screw must pass at least the thickness of the two layers of the plastic profile. One of the reasons is that the screw fixing the hinge is subjected to two kinds of forces. The second reason is that the joint strength between the screw and the profile is affected by temperature, and the hinge is fixed. The stress distribution is a pull-out force in the horizontal direction and a shear force in the vertical direction. Experiments have shown that the shear stress of plastic profiles is greater than the stress drawn. Therefore, the gripping force or the pulling strength of the screw is usually used as the riveting procedure of the screw. The higher the pull-out strength of the screw, the higher the pull-out strength of the screw fixed on the reinforcing lining of the profile is about 3 times higher than the pull-out strength of the profile without the lining. For carrying small hardware parts, it is considered that no reinforcing ribs are added. This is because the inner wall of the profile forms a balancing moment with the screw, which effectively prevents the shearing force from being broken at the joint between the screw and the profile, and accordingly increases the pulling out. strength.
