ＶＳＬ ＪＡＰＡＮ List of Products and Services

We would like to introduce the "External Cable Anchorage Device" for the VSL method that we handle. The anchoring mechanism is fundamentally the same as the anchoring mechanism used in the VSL post-tensioning method, but we offer anchoring devices and tensioning devices that are compatible with coated PC steel strands and anti-corrosion PC steel strands. The outer diameter and material are the same as those specified in the VSL method design and construction standards (VSL Association) and the PC method design and construction guidelines, and all anchoring devices allow for cable replacement. 【Features】 ■ We provide anchoring devices and tensioning devices compatible with coated PC steel strands and anti-corrosion PC steel strands. ■ The PC steel materials used for external cables in the VSL method comply with JIS G 3536 (PC steel wires and PC steel strands). ■ Cable replacement is possible. *For more details, please refer to the PDF materials or feel free to contact us.

• Special Construction Method

The "Head-bar" is a shear reinforcement rebar that has a rectangular or circular plate friction-welded to the ends of the rebar. The fixed plate firmly restrains the main rebar, effectively preventing buckling of the main rebar and providing behavior up to failure that is equivalent to that of semi-circular hook rebar. It is suitable for shear reinforcement, intermediate zone rebar, and end anchoring of main bars in densely reinforced areas of reinforced concrete floors, walls, and caps. 【Features】 ■ Simultaneously improves workability and ensures seismic performance ■ Has anchoring performance equal to or greater than that of semi-circular hooks ■ Allows for rapid installation in locations where installation with both ends having semi-circular hooks is difficult ■ Simplifies and reduces labor in rebar work ■ The fixed plate firmly restrains the main rebar *For more details, please refer to the PDF document or feel free to contact us.

• Steel bar construction

The "VSL method" is a post-tensioning prestressing anchoring method that allows for a single cable to provide a wide range of input forces, from small to massive. By using high-capacity cables, the arrangement of the cables and anchoring devices can be minimized, making it effective for bridge construction that requires large input forces. It is used in the construction of large structures such as bridges, PC tanks, domes, lifting, and block cantilevering methods. 【Features】 ■ A single cable can provide input forces ranging from small to massive ■ Post-tensioning prestressing anchoring method ■ Effectiveness in bridge construction requiring large input forces ■ Suitable for the construction of large structures *For more details, please refer to the PDF materials or feel free to contact us.

The Comet method is a removable anchor technique developed to allow for the rapid and easy removal of tensile steel materials that become underground obstacles after fulfilling the purpose of ground retention anchors. Mechanically, it is a compression-type anchor that transmits anchor force to the load-bearing body through tensile steel (unbonded PC strands). 【Features】 ○ Allows for the rapid and easy removal of tensile steel materials that become underground obstacles 　　● For other functions and details, please contact us.

It is one of the ground anchor methods using the VSL method, capable of accommodating both vertical and diagonal directions. It is effective in preventing building overturning, preventing uplift due to groundwater, preventing differential settlement, and stabilizing various structures. 【Features】 ○ It is a permanent anchor method used as part of buildings and structures as defined by the Building Standards Act, with vertical and diagonal types available. 　　● For other functions and details, please contact us.

• Foundation construction

The basic structure, materials used, construction methods, and durability are the same as conventional permanent anchor methods, but it has been improved to a system that can reliably grout the inside and outside of the corrugated sheath with a single injection pipe, and by reducing the diameter of the corrugated sheath and the drilling diameter, it is a new VSL permanent anchor method aimed at cost reduction. 【Features】 ○ A permanent anchor method that employs a corrugated sheath and ensures reliable double rust prevention measures. ● For other functions and details, please contact us.
