Three, the installation of window of model steel door standards
1 in order to guarantee the quality of window of model steel door installation, standard rules are hereby formulated. This specification applies to the model steel window (including the casement Windows, push-pull window and combination window), plastic door (including swing doors, sliding door) door window installation.
2 doors and Windows installation quality requirements.
2.1.1 the installation process used by the Windows components, parts, materials, etc in the process of transportation, storage and construction measures should be taken to prevent its damage and deformation.
2.1.2 door place should be clean, smooth, and avoid weathered. Shall be made, tilt Angle of not less than 70 °.
2.1.3 loading and unloading of doors and Windows to should take put down gently, not to pry, fall, hit, not insert prop up lifting in the sash.
2.1.4 before the installation, should check the number of doors and Windows according to the requirement of the design drawings, varieties, specifications and open direction, doors and Windows hardware, sealing strip, fasteners should be complete, not eligible should be replaced.
2.2 doors and Windows installation
2.2.1 fixed installation location should be in conformity with the embedded block, but may not be a fixed piece in a transverse frame, in the mullion, has grown two millimeters spell location, spacing between adjacent stator should be no greater than 600 mm. In addition to the fixed piece, can also be used for expansion bolt, the distance is not more than 600 mm. The location of the special bolts shall be in conformity with the project of embedded block position.
2.2.2 hang outside the window from top, find out the hole centerline and the window frame line alignment, according to the requirements of the elevation at the same time put in place, the window frame window box up and down the four corners and wedge between temporary fixation. And then adjust the levelness of the window frame vertical degree and the position of the direction of the hole in the wall thickness.
