Precast Buildings
When it comes to achieving your ultimate vision for design, color and tone, precast concrete is one of the most flexible materials available.
Castcon Value Added
Imagine an aesthetically pleasing product that is structurally sound as well as moisture-, wind-, seismic- and blast-resistant. It can also be quickly and easily erected in inclement weather. Obviously, the advantage of faster turnaround means a quicker return on investment. The stair systems in precast structures are erected with the critical path items, further increasing the efficiency of project completion.
Open Zee
This is a common design in precast structures such as parking garages and features integral landings on both ends; this means there are only two pieces to erect per level, per tower. They range from 8”-12” thickness and require “end wall” support. The Open Zee design is ideal for blast-resistant applications and design situations that require stairs with low deflection (i.e. cantilevered landings or curtain wall attachment).
L-Shaped
This is also common in parking structures and includes a full width integral landing on one side of the stair. This design is often preferred if the owner or designer wants to avoid a joint down the middle of the landings. Fully incorporated, this design uses only two units per level.
J-Shaped
This design is similar to an L-Shaped stair and offers a full width integral landing. This stair is designed with three pieces per level. The integral landing edge of the stair requires “end wall” support.
Punch-Through (or Drop-Through)
This design iscommonly used in parking structures and features a single run unit that sits in a void in the floor area of a double tee flooring system. It is supported by tube steel anchored into the double tee. Punch-Through stairs are often an economical choice for one or more towers in your parking structure.
Separate Stairs & Landings
These are often referred to as “stretchers” and contain the riser/tread run. The landings include the intermediate as well as the floor level. This design requires “side wall” support of the landings. The stairs will span from landing to landing.
