Installation process
1. Install the support and column:
According to the construction drawings, install the support of the aluminum glass window wall on the building structure.
The column should be installed vertically and firmly, and ensure reliable connection with the support.
2. Install the beam:
The beam should be installed horizontally and firmly, and the connection with the column should be reliable.
Elastic rubber pads should be set at the connection between the beam and the column to reduce friction and noise.
3. Install the sash and glass:
Choose the appropriate installation method according to the type of window wall, such as casement window, sliding window, etc.
The sash should be installed flat and firmly, and ensure the sealing performance with the window frame.
Professional glass suction cups and installation tools should be used for the installation of glass to ensure the safety and stability of the glass.
4. Install hardware accessories:
The installation of hardware accessories should be firm and flexible, and ensure its normal function.
Debug and check the hardware accessories to ensure smooth opening and closing.
5. Gluing and closing:
Glue the gap between the window wall and the wall to ensure the sealing performance of the window wall.
Process the closing of the window wall, such as using beading, cover plate and other components to ensure that the appearance of the window wall is neat and beautiful.
Quality control
1. Material quality control:
Strict quality inspection of materials such as aluminum alloy profiles, glass, hardware accessories, etc. to ensure that they meet the design requirements and relevant standards.
2. Installation quality control:
Strict quality control of each link in the installation process, such as the connection between the column and the support, the connection between the beam and the column, the installation of the window sash and the glass, etc.
Carry out a comprehensive quality inspection of the installed window wall to ensure that it meets the design requirements and relevant standards.
Common problems and solutions
1. Embedded parts installation problem
Reason: The embedded parts have different specifications, the installation position is inaccurate, and the deviation exceeds the specification control requirements.
The post-embedded parts are not close to the civil structure, the chemical anchor bolts are not cleaned in place, the anchoring depth is not enough, and the tightening is not in place.
Solution: Select the embedded parts specifications strictly according to the design requirements to ensure the installation position is accurate.
Carry out technical explanation for the embedded parts to ensure that they are close to the civil structure, the chemical anchor bolts are cleaned in place, the anchoring depth is sufficient, and they are firmly fastened.
2. Problems with the connection between the column and the main structure:
Reason: The expansion screws are used to drive into the main structure and then connected to the glass curtain wall column, which does not meet the requirements of the specification.
The same glass curtain wall column is fixed at both ends or at the lower end, and the column is not anchored and hung on the main structure to make it in a tensile working state.
Solution: The column should be connected to the embedded parts in the main structure through the connector, and the expansion screws should not be used to drive directly into the main structure.
The column should be anchored and hung on the main structure to make it in a tensile working state to ensure a firm and reliable connection.
3. Problems with the installation of the aluminum frame:
Reason: Failure to operate according to the specifications, substandard quality, excessive horizontality, verticality, diagonal difference and straightness, affecting the physical properties of the curtain wall.
Solution: Strictly follow the specifications to ensure that the quality of aluminum frame installation meets the standards.
Carry out a comprehensive inspection of the installed aluminum frame to ensure that the horizontality, verticality, diagonal difference and straightness meet the design requirements.
4. Metal material contact problem:
Cause: No anti-corrosion measures are taken at the contact point of different metal materials, such as no insulating gasket or other anti-corrosion measures are set between the column and the connector.
Solution: Set insulating gaskets or take other anti-corrosion measures at the contact point of different metal materials to prevent corrosion.
5. Weathering glue and sealant problem:
Cause: The construction of weather-resistant silicone sealant is not dense, the sealing is not strict or the length-to-width ratio does not meet the requirements of the specifications, resulting in rainwater leakage.
The size of the sealing strip does not match or the inferior material is used, which quickly loosens or ages and loses the sealing and waterproofing function.
Solution: Select qualified weather-resistant silicone sealant and sealing strip to ensure that the construction quality is dense and the sealing is tight.
Carry out a comprehensive inspection of the completed weather-resistant glue and sealant to ensure that there is no leakage.
6. Curtain wall gap problem:
Reason: The gaps between the curtain wall and the main structure, and the gaps between the floor slabs and partition walls of each floor are only sealed with ordinary decorative materials, and are not sealed with fireproof and heat-insulating materials, which does not meet the fire protection requirements.
Solution: The gaps between the curtain wall and the main structure should be sealed with fireproof and heat-insulating materials, and the inner and outer surfaces should be continuously sealed with sealants, and the joints should be tight and leak-proof.
7. Curtain wall glass problem:
Reason: The spacing between the glass fixing points does not meet the design requirements, and the fixing method is incorrect. The glass coating surface is installed in the opposite direction, affecting the use effect.
Solution: Strictly set the spacing and fixing method of the glass fixing points according to the design requirements.
Ensure that the installation direction of the glass coating surface is correct and meets the use requirements.
8. Cleaning and maintenance problems:
Reason: Failure to remove pollutants on the curtain wall surface in time, or using metal sharp scrapers and corrosive cleaners to clean, damaging the curtain wall surface.
Solution: Clean and maintain the curtain wall regularly to ensure that the surface is clean and free of pollutants.
Use suitable cleaning agents and tools for cleaning, and avoid using sharp metal scrapers and corrosive cleaning agents.
