Glass Façade/Curtain Wall

Secure Fixing with Anchor Channels. We provide design calculations for fixing curtain wall brackets to the main structural system through the use of cast-in anchor channels.

In modern buildings, glass walls are pretty common. They look cool and help with energy efficiency. But putting them up isn't easy. That's where we come in. At GFC, we're experts in making sure those glass walls stay put. We do this by figuring out the best way to attach them securely to the building's frame using special channels.

We use something called anchor channels to attach the brackets to the building's frame. These channels are like super-strong hooks that go into the building's structure. They spread out the weight evenly and make sure everything stays in place. They're adjustable too, so we can get everything lined up just right.

Complex situations in Curtain wall connection design:

1 - Thin Slabs:

When dealing with thin slabs, the structural integrity of the connection points becomes crucial. Specialized brackets and reinforcement techniques may be necessary to ensure adequate support for the curtain wall system without compromising the integrity of the slab.

2 - Building Corners:

Corners pose unique challenges in curtain wall connection design due to increased stress concentrations and differential movement. Innovative corner bracket designs and flexible connection systems are often required to accommodate these challenges while maintaining structural stability and aesthetic appeal.

3 - Very High Wind Loads:

Areas prone to very high wind loads demand robust connection designs capable of withstanding extreme forces. This may involve the use of reinforced brackets, high-strength anchor channels, and additional support elements to ensure the curtain wall system remains securely attached to the building's structure even under extreme wind conditions.

4 - Seismic Loads:

Seismic loads introduce dynamic forces that can cause significant movement and deformation in buildings. Curtain wall connection designs in seismic regions must incorporate flexible joint systems, seismic dampers, and strategic reinforcement to mitigate the effects of seismic activity and ensure the continued performance of the curtain wall system during and after earthquakes.

5 - Metal Decks:

Integration with metal decks requires careful coordination to ensure proper attachment and compatibility between the curtain wall system and the deck structure. Customized connection details and specialized fastening methods may be necessary to achieve secure and reliable attachment while accommodating the unique characteristics of metal decks.

6 - Pockets in the Slabs:

Pockets or recesses in slabs present challenges for curtain wall connections, as they may limit the available space for anchoring and support elements. Creative solutions such as adjustable brackets, recessed anchor channels, or innovative attachment methods may be required to effectively secure the curtain wall system within these constrained spaces.

7 - Lightweight Concrete:

Lightweight concrete presents challenges in terms of load-bearing capacity and structural stability. Curtain wall connection designs must account for the reduced strength and increased deflection characteristics of lightweight concrete, often necessitating specialized reinforcement techniques and careful consideration of load distribution to ensure reliable performance of the curtain wall system.

Elevator Design

Elevators are essential components of modern buildings, ensuring efficient vertical transportation for occupants and goods. A crucial aspect of elevator installation is the secure fixing of counter-weight and car brackets to the main structural system. At GFC, we specialize in providing precise design calculations for this purpose, utilizing cast-in anchor channels to ensure the safety and stability of elevator installations.

Complex situations in Evelator connection design:

1 - High Fatigue/Dynamic Loads

Elevator systems experience repetitive and dynamic loading conditions during operation, leading to high fatigue stresses on connection points. Specialized materials and fatigue-resistant designs are essential to withstand these dynamic loads over the elevator's lifespan. Additionally, dynamic analysis techniques and fatigue testing may be employed to ensure the durability and reliability of connections under varying operating conditions.

2 - Divider Beams:

Divider beams are structural elements used to separate multiple elevator cars within a shaft. Connecting divider beams securely to the main structural system involves addressing challenges such as load distribution, alignment, and compatibility with elevator car brackets. Customized connection details and robust anchoring methods are necessary to ensure the stability and integrity of divider beam installations

3 - Longitudinal Loads:

Elevator systems are subject to longitudinal forces resulting from acceleration, deceleration, and braking of the elevator car. Proper design of connections to accommodate these longitudinal loads is crucial for maintaining structural stability and preventing excessive deflection or displacement. Reinforced brackets, optimized anchor channel placements, and dynamic load analysis are essential components of effective longitudinal load management in elevator connection design.

Precast Fixing

Precise Design Calculations for Secure Installation - Precast panels offer numerous advantages in construction, including efficiency, durability, and aesthetic appeal. However, ensuring their secure installation requires meticulous design calculations and the use of reliable fixing methods. At GFC, we specialize in providing comprehensive design calculations for precast panels, leveraging cast-in anchor channels and other innovative products to ensure safe and secure installation.

1 - Sandwich Panel Anchors

Sandwich panels, comprising an insulating core between two facing panels, require specialized anchors to ensure their secure attachment to the supporting structure. Our design approach emphasizes the use of sandwich panel anchors that offer high load-bearing capacity and thermal efficiency. These anchors are carefully selected and positioned to provide optimal support and prevent thermal bridging, enhancing the energy performance and durability of the building envelope.

2 - Facing Panel Anchors

Facing panels, which form the visible exterior surface of precast structures, rely on facing panel anchors to maintain their position and resist external forces. We utilize a variety of facing panel anchors, including concealed and visible options, to meet aesthetic requirements while ensuring structural stability. These anchors are designed to accommodate the unique characteristics of facing panels, such as size, weight, and material composition, while providing reliable attachment to the supporting structure.

3 - Flexible Connection Systems

Connecting precast members often requires flexible connection systems that can accommodate movement, settlement, and differential thermal expansion. Our expertise lies in designing and implementing flexible connection systems that allow for controlled movement without compromising the integrity of the structure. Whether it's seismic joints, expansion joints, or articulated connections, we leverage advanced engineering principles to develop solutions that ensure long-term performance and reliability.
