Aluminum door pulley installation
1. the construction preparation
(2) material type and specification: aluminium profile 80 series
(3) types of glass, thickness: double insulated glass 4+6+4
(4) equipment: aluminum cutting machines, hand drills, Rotary Rasp, semicircular Rasp, Phillips screwdriver, needle, iron feet, compasses, ruler, steel ruler, steel ruler, drills, hammers, shovel, trowel, a bucket, water brush, welding, welding masks, welding lines, and so on.
2. aluminum Windows installation process line found embalmed → rules → do find is temporarily fixed window frames in place → → → plug gap around boxes and wall connections → Setup → install the sash window fixed glass → accessories → glue with clean
3. aluminum Windows 3.1 installation operation line rules
(1) plumb line: on top of the building after the Find window, with its window edge subject, under the edge with a theodolite, and identified by the layer window. Individual tick the window straight chisel trim.
(2) elastic horizontal lines: the horizontal position of the window, back up +50cm horizontal line shall prevail, measure the window height, find direct line. Each floor and elevation of the skin under the window in the same room, it should be consistent.
4. in and out of here: according to the width of the detail of the walls and sill plates, determining the wall thickness of aluminum window in and out of interest. If wall thickness deviation should, in principle, subject to the exposed width of the sill plates of the same room.
5. preservative treatment: aluminum alloy window frame around the outside shall be treated according to design drawings requirements.
6. window frames in place: after the aluminum window frames on the wall, generally placed in the hole in the mounting position line.
7. alignment temporarily fixed: State after box, adjust, correct, its vertical, horizontal, diagonal and into position, meets those requirements, temporary wood wedges fixed.
8. connection box and the wall: aluminum alloy window frame and wall connections by preinstalled frame connections with bolts and wall connections (according to the design requirements for a good lightning protection connection), specific installation methods see the tender joints.
9. plug gap around: aluminum alloy window frame after the fix is installed, should be checked for vertical, horizontal, diagonal and depth that the location is in a fixed-displacement, as does not meet the requirements, immediate corrective action, determined correctly, can be conducted around the seam. According to the design requirements addressing the gap between aluminum alloy window frame and the wall. In the process of packing, aluminum alloy window frame to prevent collision, so as to avoid deformation.
10. install the fixed glass window: glass to tear away the protective film on the window, clean the glass in place. Single piece of glass smaller sizes, using two operations in place; block size is large, glass suction cups that are available to install. Before you install the glass should be a 3mm thick elastic cushion is padded around in glass blocks, to cushion the impact of opening and closing forces. Blocks should be located in 1/4 glass side. Glass is not direct contact with the aluminium profiles and screw to prevent fragmentation. Will bead up and filling sealing and gluing according to design requirements. Sealing tape (glue) should be smooth, smooth, no loose, dense, so as to avoid water seepage.
11. install the sash 3.9.1 Installing condition: aluminum window sash installation should be carried out in civil engineering construction completed to keep aluminum Windows are intact. 3.9.2 Installing push-pull window sash: prior to installing the push-pull window sash, first tear off the protective tape, check the seal on the fan top any less or particles. If there is loss, available glass glue bonding.

13. glue and wipe
14. playing rubber: in window frames both inside and outside on both sides by wall of around Shang, and box and box Zhijian of seams at, first cut off outside box around residues of protection paper, again cleaning clean and rubber contact of real surface, then with rubber gun along gap pressure juice sealed rubber, and makes rubber surface flat, and uniform, and smooth, and no stomatal, playing rubber Hou must guarantee in 24 hours within not by vibration, ensure sealed firm.
15. cleaning: tarnish in the box, fan, glass and cement paste, adhesive traces on the windowsill and dirt, clean with wipes buqing.
