What is Concrete Tilt-Up Construction
Concrete tilt-up construction is a method of constructing a building in which large panels of concrete are poured onsite and then tilted up into place to form the walls of the building. This method of construction is typically used for commercial and industrial buildings, and is known for its speed, cost-effectiveness, and durability.
The process of concrete tilt-up construction typically involves pouring large panels of concrete on a flat, level surface, such as a concrete slab. Once the concrete has cured, cranes are used to lift the panels and tilt them up into place to form the walls of the building. The panels are then joined together using a variety of methods, such as welding or bolts, to create a solid, monolithic structure.
One advantage of concrete tilt-up construction is that it allows for a faster construction process, as the walls of the building can be constructed quickly onsite. It is also a cost-effective method of construction, as it requires fewer materials and labor compared to other methods of construction. Additionally, concrete tilt-up construction is known for its durability and ability to withstand extreme weather conditions and other forms of wear and tear.
Overall, concrete tilt-up construction is a popular method of constructing commercial and industrial buildings, due to its speed, cost-effectiveness, and durability.
Create the Rebar Cage
Concrete is stiff while metal rebar is flexible. Combining the two creates seismically resilient panels. That's why the first step in CTU construction is to tie steel reinforcing bar together to create a rebar cage.
Form and Pour the Concrete
After the rebar cages are tied, the next step is to create forms. Forms are generally wooden planks that are assembled in such a way around the rebar cages that give shape to the panel once the concrete is poured within.
Tilt the Panels
After allowing time for the concrete panels to solidify, a specialty crane crew will attach cables to engineered 'lift points' on the panels that allow for a safe and balanced hoisting of the several ton panels into the air. The panels will then be carefully guided to their final resting location and attached to the slab and footings.
