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). |

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) |
