LS form

FRC-made prestressed long embedded formwork has achieved approximately twice the bending strength through the use of reinforcement materials and prestressing.

The LS form is a long-length product that expands the range of applications for the GRC (Glass Fiber Reinforced Cement) embedded forms "KC form" and "JS form," which already have numerous construction achievements in road drainage ditch culverting work. When culverting ditches, the labor involved in traditional on-site formwork construction is eliminated, making installation easier and significantly reducing total costs. While KC form and JS form are made of GRC, the LS form incorporates a net-like reinforcement and prestressing in addition to the GRC structure. It achieves approximately twice the bending strength of conventional products. Since the pitch of the ribs and main reinforcement in the product is the same, spacers are unnecessary during concrete pouring. Each piece weighs 69 kg (for an internal width of 2500 mm), allowing for manual installation, making it efficient to work in narrow sites or steep locations where heavy machinery cannot enter. On-site processing with a diamond cutter is also easy. The load capacity is 150 kg per square meter, allowing one person to work on the product. The LS form can be used as an embedded form for culverting ditches and waterways with internal widths ranging from 1400 to 2500 mm. With the addition of the new LS form to the existing KC form and JS form, culverting work for ditches with internal widths from 250 to 2500 mm can now be handled without the need for support structures.
