I was recently invited to a half-day seminar presented by Tilt Wall, a company that specializes in tilt-up construction.
The seminar was held in a conference room and was followed by a tour of the site.
As luck would have it, we visited a construction site that AGF Rebar had worked on. On the day of our visit, all of the walls were lying flat and were in the process of being prepared, so I didn’t have a chance to see the procedure first hand.
- First, there must be a flat work surface such as a concrete slab that could later serve as a school playground.
- A non-adhesive chemical product is applied to the top surface of the temporary slab so that the permanent concrete panels can then be easily removed.
- Forms are made only for the lateral thickness of the panels and openings. Obviously, there is no need for bottom or top forms.
- Each opening and element that is cast, including the lifting hooks, must be coordinated and detailed to perfection.
- Once the concrete has set, each panel is lifted to its permanent location.
- Most of the wall panels for these projects are 400 mm thick, including an interior layer of rebar-reinforced concrete with 15M to 25M rebar, a layer of insulation between the two and another layer of reinforced concrete (WWM or Fibre).
- Various embossed shapes or paint can be used on the exposed surfaces. For example, for a school project, children’s handprints were used.
- Tilt-up is a method in which concrete wall panels are poured on site and lifted into position.
- Tilt-up was first mentioned in a quotation from Thomas Edison in 1903: “Tilt-up construction eliminates the costly and cumbersome practice of building two wooden walls to obtain a single concrete wall.
- In 1908, Thomas Edison created Union, New Jersey, a village consisting entirely of tilt-up concrete houses that are still standing today.
- The most efficient tilt-up projects are two-storey walls.
- Tilt-up is becoming increasingly popular for building schools and institutional projects in Ontario.
- Tilt-Wall is an established tilt-up contractor that has worked with AGF Rebar since 2006.
- Our first tilt-up construction project was Building B at Humber College with Tilt-Wall, which won a Concrete prize in 2009.
Here are some photos from the site.
Kudos to the entire team!
SEMINARIO DE TILT WALL
Recientemente fui invitada a un seminario de medio día organizado por Tilt Wall, una empresa que se especializa en la construcción con la técnica Tilt-Up (por levantamiento).
El seminario se realizó en una sala de conferencias seguido de una visita de la obra.
Casualmente la obra que visitamos era un sitio de construcción en el que participaba AGF Rebar. Sin embargo, el día de nuestra visita todos los muros estaban siendo preparados horizontalmente. No tuve la oportunidad de ver la técnica de construcción Tilt-Up en curso.
Las etapas de construcción con la técnica Tilt-Up son las siguientes:
Algunos hechos interesantes sobre la técnica Tilt-Up:
A continuación le presentamos algunas fotografías de la obra.
¡Felicidades a todo el equipo!
