Office Glass Curtain Wall Bonding (T3 Bayside Office Building, Toronto)
2025/04/09
Core Requirements
- Strength: It needs to withstand wind loads, seismic effects, etc. According to the design specifications, under the wind load standards in the Toronto area, the bonding strength of the structural adhesive needs to reach a specific value. Generally, the tensile - adhesive strength of silicone structural sealant should not be less than 0.60MPa under standard conditions. In actual projects, the appropriate bonding area and thickness need to be determined through calculation to meet the strength requirements.
- Weather Resistance: With cold winters and hot summers in Toronto, the sealant must have good weather resistance. For example, the Baiyun brand ss621 silicone structural sealant has withstood the test of the natural environment for 25 years. The average tensile strength still reaches 1.12MPa, the hardness is 48, and the elasticity is good.
- Sealing: Prevent the penetration of rainwater and air. The water - tightness should meet the requirement of no leakage under a certain rainfall, and the air - tightness can reduce heat loss.
Project Solutions
- Material Selection: Select high - quality silicone structural sealants, which have high strength, good weather resistance, and sealing performance. Brands such as Dow Corning and Baiyun are preferred.
- Construction Technology: The positioning error between the glass and the secondary frame is controlled within ±1.5mm. Clean the surface before gluing, and protect the surrounding 5cm area with non - stick tape. Use mechanical gluing, and control the gluing speed properly to prevent cavities and bubbles. After gluing, use a scraper to compact and smooth the glue.
- Quality Control: Conduct dimensional measurement, physical property (tensile strength, elongation at break, etc.) and chemical analysis tests on the structural sealant. In - site detection methods include the airbag method and the push - rod method. Measure the displacement of the silicone structural sealant to evaluate the bonding condition.
Achieved Results
- Safety: Through mechanical tests and practical environmental tests, the glass curtain wall is firmly bonded, which can effectively withstand wind loads, earthquakes, and other disasters, ensuring the safety of personnel and the building.
- Durability: The selected sealants with good weather resistance have not shown obvious aging, cracking, and other problems affecting performance during long - term use, reducing maintenance costs.
- Sealing: Effectively block the penetration of rainwater and air, improve the building's thermal insulation performance, and create a comfortable indoor environment.
