Information
  Aluminum plastic panel construction technology and process
  1, measuring and setting out
  1) According to the axis and elevation line on the main structure, the installation position line of the support frame should be accurately bounced onto the main structure according to the design requirements.
  2) Punch out all the embedded parts and re-measure their dimensions.
  3) The distribution error should be controlled when measuring and setting out, not the accumulation of error.
  4) The measurement and setting-out should be carried out under the condition that the wind force is not greater than level 4. After setting the line, it should be checked in time to ensure the verticality of the curtain wall and the correctness of the column position.
  2. Install the connecting piece to weld and fix the connecting piece with the embedded piece on the main structure. When no embedded iron parts are embedded in the main structure, expansion bolts can be drilled on the main structure to fix the connecting iron parts.
  3, install the skeleton
  1) According to the position of the spring line, the rust-proof column shall be welded or bolted to the connecting piece accurately. During installation, the elevation and centerline position should be checked at any time. For the outer wall aluminum curtain wall frame column with larger area and higher floor height, it must be measured with measuring instruments and wire fall to correct its position to ensure that the frame vertical rod is vertical and flat. The elevation deviation of the column installation should not be greater than 3mm, the front and rear deviation of the axis should not be greater than 2mm, the left and right deviation should not be greater than 3mm; the elevation deviation of two adjacent columns should not be greater than 3mm, and the maximum elevation deviation of the column on the same floor should not be greater than 5㎜, the deviation of the distance between two adjacent erections should not be greater than 2㎜.
2) Install the connectors and gaskets at both ends of the beam at the predetermined position of the column, and the installation should be firm, and the joints should be tight; the horizontal deviation of the two adjacent beams should not be greater than 1 mm. The elevation deviation of the same floor: when one When the width of a curtain wall is less than or equal to 35 m, it should not be greater than 5 mm; when the width of a curtain wall is greater than 35 m, it should not be greater than 7 mm.
  4. Install fireproof materials
  High-quality fireproof cotton should be used, and the fire resistance period should meet the requirements of relevant departments. Fix the fireproof cotton with galvanized steel plate. The fireproof cotton shall be continuously sealed in the space between the floor and the metal plate to form a fireproof belt without any gap in the middle.
  5, install aluminum plate
  Use rivets or bolts to fix the aluminum alloy plate finish on the steel frame piece by piece according to the construction drawing. Leave 10~15mm seam between the board to adjust the installation error. When the metal plate is installed, the deviation between left and right, up and down should not be greater than 1.5 mm.
  6, processing board seam
After cleaning the surface of the metal plate and frame with a detergent, immediately place a sealing strip or weatherproof tape in the gap between the aluminum plates, and then inject materials such as silicone weather-resistant sealant. The injection should be full without gaps or gaps. bubble.
  7, processing curtain wall closing
  The closing treatment can use metal plates to cover the end of the wall and the keel.
  8. Deal with deformation seams
  The treatment of deformation joints must first meet the needs of building expansion and settlement, and at the same time, it should also achieve a decorative effect. The heterosexual gold plate and neoprene belt system can often be used.
  9. Clean the board surface
  Remove the protective tape on the board and clean the board.
