Product Details

Eco-friendly Floor formwork
( Certified Innovative product by K-PPS )

It was developed with the goal of drastically reducing costs and stabilizing the quality by substituting the high-functional composites floor formwork for the PSC girder construction. The H.F.C floor formwork is a plastic eco-friendly formwork that can reduce construction costs, improve workability as well as reduce logistics and storage costs with the optimized design of the girder type.

H.F.C Eco-friendly Floor formwork

( Certified Innovative product by K-PPS )

Product		HFC ECO-Friendly Floor Formwork (recently developed as a bed for manufacturing cast in situ PSC girder)
Shape
Major clients		• All government agencies or contractors in charge of bridges • Sub-contractors or bridge-oriented companies that constructs PSC girders on site
Overview		• The world's first modular floor formwork: The H.F.C floor formwork is a plastic eco-friendly formwork that developed with the goal of construction safety, quality stability and cost savings for the cast-in-site PSC girder construction. • By replacing old materials(square lumbers, steel plates) and using H.F.C floor formwork, it is anticipated to achieve cost savings(time and manpower) and better quality control(stiffness and shear key) and easier application(light weight).
Comparison		Conventional way HFC floor formwork Layer of lumbers and steel plates(left) Bad quality & ugly appearance(right) Simple and easy installation(left) excellent quality & clean appearance(right)
Advantages	Operation	• Short construction period, safer working condition, better quality control, easier storage and cheaper logistics → Finally SOC budget savings in total
	Eco-friendliness	• Recyclable Plastic Formwork & no need to logging for lumbers • CO2 reduction by shorter working time
Reference		• Many expressway projects of EX such as Anseong-Yongin, Sejong-Anseong etc. • Railway bridge in the Pohang Youngilman new port link project (KR) • Some road bridge projects of LH such as Gwachen route 47 bypass project etc. • Local government projects such as Gimhae, Andong, Chilgok etc.

Structural stability of H.F.C floor formwork

• Prevention differential settlement due to un-flatness and poor bearing capacity at site (Prevention of lateral sweep)
• 3 times more contact area, a quarter deflection and 6 times stiffness against conventional method

Comparison with conventional methods

Item	Conventional method (Square lumber & steel plate)	H.F.C floor formwork
Installation on site
Patent	X	No.10-1614833
Loading test	X	Accomplished at KCL in Oct, 2017
References	thousands of (for a long term, conventional way)	• Many road and railway bridge projects as below; • Railway bridge in the Pohang Youngilman new port link project (KR) • Road bridge in the Honamseon improvement project (KEC) • Local governments such as Jeonnam, Gangwondo
Technical overview	Square lumbers and steel plates are used to construct the floor formwork of the cast-in-place girder, but it is difficult to reuse(less than 3 times) and there are problems with quality degradation such as damage to the structure due to deflection and deterioration of appearance.	The H.F.C floor formwork, developed to solve the problems of conventional methods, is a plastic eco-friendly formwork that can reduce construction costs, improve workability as well as reduce logistics and storage costs with the optimized design of the girder type.
Work flow	complicated and difficult Laying of stone powder --> square lumber (longitudinal, transversal) --> steel plate	simple and easy Laying of stone powder --> Install floor formwork
Key features
Quality	Sagging of steel plate joints and sagging (swelling) between square lumbers due to materials with non-uniform stiffness and errors due to non-standardized installation methods	Based on structural stability (optimized design, special material with excellent stiffness), existing problems are solved, and structural reinforcement and sagging problems are eliminated by applying a shear key
Constructability	Low efficiency due to separate assembly of heavy steel plates and square lumbers	Can be easily installed, moved, and dismantled as an integrated unit 40% shorter construction period compared to the conventional method
Weight per meter	About 60kg/M (Heavy to handel)	About 20kg/M (66.7% lighter) (Light enough to handle)
Cost of logistics	High cost due to heavy steel plate and non-uniform shape(lumber)	Low by low weight and standardized size (80% cheaper than conventional way)
Durability	Lumber: less than 3 times Steel plate: good	Excellent (Semi-permanent use available) (high strength and functional composite material)
Eco-friendliness	Lumber waste and continuous logging needs	Re-usable and reducing CO2
Cost	70USD/m x 100% = 70USD/m (average cost in the market)	80USD/m x 82% (bid rate) = 65.6USD/m (Roughly 8% cheaper)
