Building curtain wall construction points

1. Measurement and release

According to the relevant data provided by the large sample curtain wall drawings and the civil engineering units, the benchmark lines such as the surface of the curtain wall, the main body, the grid division and the rotation angle are determined, and the measurement and release line of the curtain wall grid axis are adjusted and repeated through the latitude and weft meter axis. It is necessary The curtain ranging axis can be changed in a small range to adapt to the curtain wall structure. When measuring and releaseing high -rise buildings, the wind power of the measurement environment must not exceed 4 levels; if the deviation of the burial parts exceeds 45mm, it must be treated before installation and put forward the handling opinions to the relevant units.

2. Install the curtain wall skeleton

Fix the column and connect the column to the buried part of the subject. The verticality of the column is adjusted by the vertical control line, which is detected by the latitude and weft meter or hammer. The height of the column can reach 1 layer or 2 layers, and the seams between the column can be connected through the sleeve. In order to avoid deformation of the glass curtain wall due to temperature and other changes, 10 20mm spacing should be left at the seam. The beams are usually installed from the bottom up. The connection between the beam and the column is connected with a bolt. The level deviation of the two adjacent beams is not greater than 1mm, the level deviation of the same layer beam is not greater than 5mm, and the deviation from the surface of the column is not greater than 1mm.

3. Top treatment of the building curtain wall

The top of the curtain wall is closed on an aluminum gusset or galvanized iron plate to prevent the damage of rain and snow and hail to the curtain wall, and the curtain wall should also be closed. If there are walls, beams, and columns behind the curtain wall, it is best to brush dark paint before the curtain wall construction to improve the shooting effect. In addition, before removing the scaffolding, it should be carefully cleaned and repaired.

4. Install glass

Before installing the glass plate, the glass plate should be stacked according to the level specifications, the glass should be cleaned and stacked according to the level, and the glass should be stacked in order at the same time. When stacking, it should be appropriately tilted to avoid turning the glass. After the glass plate is installed, adjust the tablet, and the adjustment standards are horizontal, vertical and flat. The horizontal plane is a horizontal beam, and the gel sewage is horizontal; the vertical beam is vertical, the gum joint is vertical; the plane is the same plane or the glass on the curved surface. After the outdoor adjustment, it is necessary to check whether the indoor is in line with the standard and whether the size meets the design requirements. After the glass plate is adjusted, it is fixed. When the rubber pad is fixed, the pad should be actively pressed to end the loosening of the glass plate. In the process of installing glass, quality and acceptance should be strictly controlled.

5. Install the fulcrum iron component

The vertical fulcrum is generally set according to the floor number of the floor or vertical material. The horizontal fulcrum should be considered and the size of the room should be considered. As a whole, the curtain wall should be evenly divided, and the ratio of height to width should be symmetrical. The fulcrum requires vertical upward and downward, horizontal levels, and all fulcrum must be guaranteed on the same plane. When installing the curtain wall aluminum skeleton, the vertical material should be installed first, and then the horizontal material should be installed. The stainless steel or zinc galvanized mechanical bolt should be used at the profile connection. The profile cutting and installation should be numbered sequentially. The glass cutting and installation should be clear (the coating should be inside the curtain wall). The glass installation should be up and down first, the surrounding cracks and frame cracks should be appropriate. The key to sex and qi.
