Glass Curtain Wall Installation And Solutions
Curtain wall double-layer architectural glass usually refers to a curtain wall system composed of two or more layers of glass. This system can effectively improve the thermal insulation, sound insulation and energy-saving performance of the building.
Installation steps
1. Site survey and preparation
Before installation, a detailed survey of the building site is required to ensure that the design of the curtain wall meets the actual situation, especially the flatness and verticality of the wall.
Check the exterior wall of the building to ensure that it is flat and solid, and complete the installation of the steel structure.
Prepare the required installation tools and materials according to the site conditions, such as hoisting equipment, sealant, brackets, etc.
2. Measurement and processing
Accurately measure the size of the glass to ensure that the glass is processed into tempered glass or insulating glass that meets the design requirements.
For glass that cannot be cut on site, such as tempered glass and insulating glass, the actual size should be checked in advance, and the center position of the connection point between the frame material and the main structure should be adjusted as needed.
3. Installation and fixing
Use hoisting equipment to safely hang and fix the glass to the predetermined position.
Arrange the connected glass according to the design drawings to ensure accuracy.
Unit curtain wall installation should be carried out from bottom to top, and component curtain wall frame materials should be installed from top to bottom.
During the installation process, precise measurements should be made using tools such as level and theodolite to ensure the flatness and verticality of the glass panel.
4. Sealing and closing
After the glass is installed, use silicone sealant to fill the gaps to ensure the thermal insulation and waterproof performance of the curtain wall.
For the gaps in the unit curtain wall, V and W-shaped or other types of strips should be used to seal, and the filling should be dense and not missed.
Ensure that the glass curtain wall has reliable closing on the door and the door edge to meet the installation and maintenance requirements of equipment such as automatic revolving doors.
5. Inspection and maintenance
After the installation is completed, a detailed inspection should be carried out, including appearance inspection, sealing test, cleaning and maintenance, etc.
Clean the curtain wall glass regularly to maintain its transparency and beauty. Neutral detergents should be used for cleaning, and highly corrosive chemicals should be avoided.
Solutions
1. Solve the problem of broken glass
During transportation and hoisting, use special protective materials and operate carefully to avoid glass breakage.
For broken glass, replace it in time and reseal it.
2. Solve the problem of poor sealing
Ensure the quality of the sealant and strictly follow the specifications during installation.
For poorly sealed parts, reapply the sealant and perform a sealing test.
3. Solve the problem of uneven installation
Use tools such as levels and theodolites for precise measurement to ensure flatness and verticality during installation.
For uneven parts, adjust or reinstall them.
4. Optimize energy-saving performance
Select glass materials with good energy-saving performance, such as Low-E glass.
Fully consider the selection of insulation strips and the increase of insulation distance in the design to improve the energy-saving performance of the curtain wall.
5. Reduce costs
Reduce unnecessary waste and repetitive work by optimizing the design and construction plan.
Select cost-effective materials and equipment to reduce the cost of curtain walls.
In summary, the installation and solution of curtain wall double-link architectural glass needs to comprehensively consider the site conditions, design requirements, material selection, construction technology and post-maintenance. Through careful planning and strict implementation of the construction process, the safety, beauty and service life of the curtain wall can be ensured.
Maintenance precautions
1. Cleaning cycle and selection of cleaning agents:
Determine the number and cycle of cleaning the curtain wall according to the area and degree of pollution of the curtain wall, and it should be cleaned at least once a year.
Toxic or corrosive cleaning agents shall not be used when cleaning, and cleaning fluid is not allowed when cleaning the coated glass film surface. It must be wiped with a soft, pure cotton cloth.
2. Regular inspection and maintenance:
When the glass curtain wall project is completed and accepted for one year, the construction unit shall conduct a comprehensive inspection.
For glass curtain walls assembled by structural bonding, if they have been delivered and used for 10 years, it is advisable to conduct a sampling inspection of the bonding performance of silicone structural sealants according to the situation, and then conduct an inspection every 3 years.
Regularly check the curtain wall drainage system and clear it in time when blockage is found.
Regularly check the lightning protection connection. If it is found that the component is not connected to the main structure or is rusted or has insufficient overlap, it should be repaired and replaced in time.
