Elevated Floor Slab

Deflection of form w o r k and s h o r ing during concrete.

Elevated floor slab.

A raised slab foundation is a cross between a slab and a crawl space. Elevated concrete slabs are problematic since those slabs tend to have camber built into the design and the floor slabs will generally sag once the support staging is removed. Our gridd system is a paradigm shift in thinking about raised flooring. Then they fill the entire crawl space with rock or soil for drainage and cap it with a layer of concrete.

The installer builds a base structure of footings and a perimeter wall to support the home. Contractor and engineer responsibilities an out of level elevated slab may be caused by. Elevated floor system which is also termed as access floor system is a raised structural floor that is placed on a reinforced concrete slab. A raised floor also raised flooring access floor ing or raised access computer floor provides an elevated structural floor above a solid substrate often a concrete slab to create a hidden void for the passage of mechanical and electrical services.

An elevated or suspended concrete slab is most commonly found in multistory heavy use buildings such as parking garages or commercial offices. Effects of concrete placing and fin ishing operations on floor flatness will be discussed in a subsequent a rt i c l e. These homes are faster to build as well. Fortunately selecting the most appropriate system can help minimize formwork costs.

The elevated floor system consists of a several panels as shown in figure 1 which are installed on vertical adjustable pedestals as it can be noticed in figure 2. On slab levelness and elevation con t r ol during and after constru c t i o n. A monolithic concrete slab will typically cost 4 500 to 12 000 which is cheaper than either a crawl space or a basement. It has stronger floors without rot sagging or creaking.

Ask yourself what building design doesn t deserve easy flexible access to power voice and data wherever. Raised floors are widely used in modern office buildings and in specialized areas such as command centers information technology data. Therefore f l numbers are only specified on elevated slabs when measurements are taken before shores and forms are removed and the slab has no camber. Many factors need to be taken into account when designing an elevated concrete floor not only to take into account the weight of the floor but also the effect of additional loads on the concrete.

Also called raised flooring access flooring or raised access computer flooring a raised floor is a construction model in which an elevated floor is built above a building s original concrete slab surface thereby creating a hidden void between the two floors that is used for the passage of mechanical and electrical services. To do that the contractor must understand the different forming systems available today and must weigh a number of factors as they apply to the particular job.
