Construction contractors prefer precast concrete double tees because they are strong, flexible, and easy to install.
However, among many subtle details regarding building construction, the application of warping in double tees must be considered.
Refrain from letting water ruin your project, and understand the importance of warping in double tees to avoid mould, drainage, etc.
This blog post will discuss the following points: the role of warping in double tees, how it increases drainage, and, lastly, the benefits of warping double tees to achieve longer-lasting and better-performing constructions.
Precast Concrete Double Tees
Precast concrete double tees are elongated structures consisting of two “T” beams placed adjacent. Precast concrete products are ideal because they are prefabricated from a factory environment and assembled onto the building project site. This process of prefabrication has many benefits over conventional construction methods and practices.
Key Features and Benefits:
- Strength and Durability: Double tees are designed to bear significant loads and extreme weather conditions. They are long-lasting in operation and require little maintenance after that.
- Versatility: They can be used in a variety of applications, including:
- Parking garages
- Industrial buildings
- Commercial structures
- Residential buildings
- Bridge decks
- Speed of Construction: Precast double tees can cut down construction time. They are easier to install and complete a project quickly, hence the savings.
- Cost-Effective: Prefabrication achieves high accuracy and low waste in building construction, resulting in cost savings.
- Improved Safety: Factory-controlled production will minimise risks within the construction site, making construction safer for the workers.
- Design Flexibility: Double tees can also be fabricated to suit various design specifications, such as span lengths, load-bearing capacity, and aesthetic requirements.
Warping In Double Tees
Warping, a process that demands careful planning and execution, is a technique used to create a slope in elements like double tees. This expertise is employed to enhance the drainage of rainwater and melting snow in the construction of parking structures.
Importance Of Warping In Double Tees
Adequate Drainage: This is because rain and snow melt are efficiently directed towards drainage points by creating a slight slope towards them. This prevents water from pooling on the surface, which can lead to structural damage, mould growth, and slip-and-fall accidents.
Reduced Maintenance Costs: Proper drainage minimises costs such as cleaning and repairs within a given environment. Water on the surface becomes a root cause of concrete deterioration since it forms cracks and leaks. Warping is used to significantly reduce the time and costs of these problems, providing a substantial financial benefit.
Enhanced Durability: Proper drainage prevents water from seeping into the concrete, which can cause freeze-thaw cycles. These cycles may diminish the framework. Warping protects against such damages, thereby increasing the life expectancy of the double tees.
The Importance Of Warping In Double Tees For Effective Drainage
Warping for Drainage:
Warping double tees is a construction practice that facilitates the integration of slopes for drainage in parking garages.
One corner of the double tee is intentionally lowered to achieve the required slope. This is typically done during casting, where the formwork is adjusted to create the desired slope. The corner is then supported at the lower level until the concrete has cured, ensuring the slope is maintained. This process, known as warping, is a crucial step in the construction of double tees for effective drainage.
Warping is more effective for the longer double Tees (≥ 50 ft). Shorter tees have some constraints because they lack flexibility, which is lacking in longer ones.
Drainage Considerations:
Minimum Slopes: A minimum slope of 1.5% is recommended, but 1% is acceptable after considering construction tolerances.
- ADA Accessibility: The slopes of the accessible parking area shall not be more excellent than 2%.
- Headroom Clearance:
- Camber: The drainage design must account for the inherent camber of prestressed double tees.
Additional Factors:
- Structural Integrity: Warping applications require careful execution to reduce any adverse effect on the double tee’s structural capability.
- Construction Tolerances: Construction tolerances may influence the actual drainage provided in construction, so great attention must be paid to them.
- Local Building Codes and Standards: Complying with the region’s building codes and standards is not just a requirement but a professional responsibility in construction.
