EFCO LITE COLUMN FEATURES
Pre-drilled holes allow forming of multiple column sizes
Three bolts per corner in an 8′ form
No need for exterior walers or rods
Produces a superior concrete finish
2,000 lbs/ft2 pour pressure
Lightweight at 12 lbs/ft2
Customizable & Efficient Column Formwork
For high-rise buildings, the EFCO LITE® system can be customized to meet the needs for specific requirements. Repetitious columns with intersecting spandrel beams can be formed very efficiently. EFCO LITE custom column and beam applications include apartment buildings, office complexes, and high-rise hotels.
Benefits of EFCO LITE
With quick and easy assembly, EFCO LITE® column forms require only three EFCO Quick Bolts® per 8′ high column corner. This allows for quick stripping and resetting.
Easy to handle and lightweight, EFCO LITE forms weigh only 11 lb. per sq. ft. This greatly reduces crane size and allows individual panels to be manhandled.
Varying heights are achieved with different panel heights of 8′, 4′, 2′ and 1′.
Adjustable Column Sizes
The adjustability of column sizes is achieved from a single form from 10″ to 30″ (in 2″ increments) are possible from three available standard set-ups.
Durable Column Forms
All-steel EFCO LITE® Column Forms can withstand constant reuse and produce a consistent concrete finish.
Bypass corners assure a leak resistant form for good concrete corners and provide a “self- squaring” system.
Easily Attached Chamfer Inserts
Fishtail chamfer inserts attach easily and stay attached with flush flat-head bolts. Chamfers do not become loose parts to deal with during stripping and setting.
Consistent Concrete Finish
All steel construction with a high-strength 1/8″ thick steel face sheet produces a consistent flat concrete finish.
Question & Answers
How Long Should Concrete Cure Before Removing Formwork?
The duration of time between placing concrete and removing/stripping formwork and shoring depends on a variety of factors, but it is ultimately based on age criteria and the minimum concrete strength determined by the project engineer (reference ACI 347-R14; 5.7.1).
How Do You Determine the Pressure Exerted on Formwork When Pouring Concrete?
Concrete form pressure is determined based on the height of the concrete. The height of concrete times the density of concrete will determine the pressure exerted on the forms at a given depth. As concrete transitions from a flowable liquid mix to a solid, the concrete will no longer continue to build pressure with depth. Monitoring this transition point is important to ensure the allowable pressure on the forms isn’t exceeded. For more information, see “A Practical Guide to Concrete Pressure & Formwork”
What are the Standard Sizes Available with EFCO LITE Column Formwork?
EFCO LITE® column forms are available in three standard widths to handle columns 10″ X 10″ to 30″ X 30″ and all the rectangular combinations in between. For example, a 30/24 column form can be used to form columns 24, 26, 28, and 30 inches. All with one standard column panel. As for heights, a variety is available with panel heights of 8’, 4’, 2’, and 1’.
What Is the Lateral Concrete Pressure / Pour Pressure Of EFCO LITE?
EFCO LITE® Column forming system has a 2,000 lb. per sq. ft. lateral concrete pressure (pour pressure).
