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.

basic information
1. Streamlining on-site construction No support, elimination of demolition work, elimination of residual materials. 2. Improvement of workability • Since the pitch of the product's ribs and main reinforcement is the same, spacers are unnecessary. • Product weight: 69kg/piece (W=2700), allowing for manual construction. Efficient work can be done even in narrow sites where heavy machinery cannot enter or in steep locations. • Load capacity of 150kg/m². Work can be performed on top of the product. *Please do not have more than two people on one piece. 3. Protection of forest resources by not using plywood 4. Easy on-site processing with diamond cutters Applications ● Embedded formwork for long spans Side ditch and underground drainage formwork with a groove width of 1400mm or more, formwork for buildings and bridge slabs, etc. ● Large residual formwork Residual formwork for CSG dams, sediment control dams, retaining walls, etc., panel repair methods, etc. Adjustment of tension (strength, position) according to usage conditions is possible. If you have any questions or requests, please contact your sales representative. Supports waterway widths from 1400mm to 2500mm.
