Aluminum alloy doors and windows installation

Aluminum alloy doors and windows installation
1. Positioning and laying-off: the glass door combined by fixed glass and movable glass door leaves, uniformly laying-off and positioning. According to the requirements of the design and construction drawings, release the positioning line of the glass door, determine the position of the door frame, and accurately measure the ground elevation, the elevation of the top of the door frame, and the elevation of the middle horizontal frame.
2. Limit slot at the top of the mounting frame: The width of the limit slot should be greater than the thickness of the glass by 2-4mm, and the slot depth should be 10-20mm. When installing, first draw out two metal decorative board edges from the center line of the bullet, and then install the limit slot on the top of the door frame according to the edge lines. Adjust the groove depth in the groove by gluing the pad. In addition to the wooden lining, the limit slot is made of 1.5mm steel plate pressing, steel plate welding, and aluminum metal profiles. The lining is made of stainless steel.
3. Install the wooden bottom bracket with metal veneer: first fix the square wood on the ground, and then glue the metal veneer to the wood with all-purpose glue. The square wood can be directly nailed to the embedded wooden brick or through expansion bolts The connection method is fixed. If an aluminum alloy square tube is used, it can be fixed on the frame column with aluminum angles, or fixed on the wooden bricks buried in the ground with wood screws.
4. Install the vertical door frame: connect the center line of the bullet and nail the square wood of the door frame, and then use plywood to determine the shape and position of the door frame column. Finally, the metal decorative surface is covered. When decorating the bag, place the front seam of the decorating face at the middle door position on both sides of the installation glass. The seam position must be accurate and vertical.
5. Install the glass: Use the glass suction cup machine to suck the thick glass tightly, then hold the suction cup to lift the thick glass plate by 2-3 people and move it to the installation position. Then insert the upper part of the glass into the limit slot on the top of the door frame. Then put the lower part of the glass on the bottom support. The lower part of the glass is aligned with the center line, and the edges on both sides just seal the metal decoration outside the door frame to the seam. It is required that the decoration is not visible inside and outside the seam.
6. Fix the glass: Nail two small square wooden strips inside and outside on the bottom square wood to clamp the thick glass in the middle door. The square wooden strip is about 4mm away from the surface of the glass plate. The veneer metal is glued to the square wooden strip.
7. Sealing with glass glue: inject glass glue to seal the gaps on both sides of the top limit slot and bottom bracket opening, as well as the gap between the thick glass and the frame column. Start at the end of the gap and pour it along the gap at a constant speed to make the glass glue form a straight line with a uniform surface outside the gap, scrape off the excess glass glue with a plastic sheet, and wipe the glue trace with a cloth.
8. Butt joint between glass: When the fixed part of the glass door needs to be spliced ​​glass due to the large size, the seam should have a width of 2-3mm, and the edge of the glass plate should be chamfered. After the glass is fixed, inject glass glue into the butt joint. After filling, use a plastic sheet to smooth the glue on both sides of the butt joint of the glass plate to make the gap form a clean and uniform straight line. Wipe the glue trace with a clean cloth on the glass surface.
9. Installation of movable glass door leaf: Before the door leaf is installed, the positioning pin on the ground floor spring and the top surface of the door frame should be positioned and installed. The two must be coaxial. Check with a hanging vertical line during installation.
