1. Installation process
1. Lofting and installation of supports
According to the shape, size and drawing requirements of the curtain wall, the curtain wall is laid out and marked.
Ensure that the number, specifications, position and anti-corrosion treatment of various embedded parts meet the design requirements.
Set a connecting fixed support between the curtain wall frame and the building structure, and the upper and lower supports must be on a vertical line.
2. Install columns and beams
Between the two fixed supports, use stainless steel bolts to fix the columns according to the installation elevation requirements, and ensure that the column installation axis deviation and the installation elevation deviation of the two adjacent columns are within the allowable range.
Determine the elevation of each beam on the column, connect the beam and the column with aluminum angles, and set elastic rubber pads at the contact point.
3. Install glass
Choose a suitable installation method according to the type of curtain wall (such as exposed frame curtain wall, hidden frame curtain wall, semi-hidden frame curtain wall, etc.).
For exposed frame curtain walls, use pressure plates and rubber to fix the glass on beams and columns.
For concealed frame curtain walls, use structural silicone glue to bond the glass to the aluminum alloy frame to form a glass unit block, and hang it on the beams and columns.
For semi-concealed frame curtain walls, combine the installation methods of concealed frame and exposed frame.
Ensure that there is a certain gap between the glass and the components, and place elastic positioning pads and inlaid rubber strips.
4. Gluing and cleaning
After the glass is installed, glue treatment is carried out to ensure that the temperature and humidity of the glue meet the requirements of relevant specifications.
Clean the contaminated glass and aluminum profiles to keep the curtain wall clean and beautiful.
FAQ
Q: The embedded parts have different specifications, the installation position is inaccurate, and the error exceeds the standard control requirements.
A: Timely and accurately place the embedded parts during the main construction process, and ensure that the embedded parts are firmly buried and accurately positioned.
Before the curtain wall is installed, re-test the embedded parts, and adjust the curtain wall grid and deviation according to the inspection results.
Q: The fixing method of the column does not meet the requirements of the specification, such as using expansion screws to drive into the main structure for connection, or the two ends of the column are fixed but the lower end does not form a movable connection.
A: The column should be connected to the embedded parts in the main structure through the connector, and the expansion bolts should not be driven into the main structure for connection.
Ensure that the material, specification and quantity of the connector, insulation sheet and fastener meet the design requirements, and check the rust prevention and adjustment range of the connector.
Q: The aluminum frame is not installed according to the specifications, resulting in excessive horizontality, verticality, diagonal difference and straightness.
A: Install the aluminum frame strictly in accordance with the specifications to ensure that the horizontality, verticality, diagonal difference and straightness meet the standards.
Strictly check the installation quality and rectify problems in time.
Q: No anti-corrosion measures are taken at the contact between different metal materials, such as no insulating gasket between the column and the connector. Solution: Install insulating gaskets or take other anti-corrosion measures at the contact points of different metal materials.
A:Regularly check the anti-corrosion of metal contact parts and deal with problems in time.
Q: The construction conditions of structural adhesives and sealants are not taken seriously, such as weather-resistant sealants in the rainy season, which makes the sealing quality unguaranteed.
The sealant strips are not of the same size or are made of inferior materials, which will soon loosen or age and lose the sealing and waterproofing function.
A: Install the aluminum frame in strict accordance with the specifications to ensure that the horizontality, verticality, diagonal difference and straightness meet the standards.
Strictly check the installation quality and rectify problems in time.
Q: The gaps between the curtain wall and the main structure, and the gaps between each floor slab and partition wall are only closed with ordinary decorative materials, and fireproof and heat-insulating materials are not used to fill them.
A: The gaps between the curtain wall and the main structure should be filled with fireproof and heat-insulating materials.
The inner and outer surfaces should be continuously sealed with sealants, and the joints should be tight and leak-proof.
Q: The curtain wall glass does not use safety glass, or the heat-reflective coated glass is installed in reverse.
A: Curtain wall glass must use safety glass, such as tempered glass, laminated glass, etc.
The coated surface of the heat-reflective coated glass should face the interior, and the insulating glass coating should be on the second side.
In summary, luxury energy-saving curtain wall glass may encounter a variety of problems during installation and use, but these problems can be effectively solved and the normal use and long-term stability of the curtain wall glass can be ensured by strictly following the requirements of the specifications, strengthening quality inspection and acceptance, selecting high-quality materials and accessories, and regular maintenance.
