The "Kaiser Railway Elevated Bridge Slab" is a rational slab that uses high-quality precast components manufactured in a factory, enabling the construction of elevated bridges that excel in durability and cost-effectiveness. Compared to conventional cast-in-place slabs, it does not require formwork or shoring, which reduces construction noise and minimizes material yard requirements, contributing to shorter construction timelines and lower total costs. Please feel free to contact us if you have any inquiries. 【Features】 ■ Shortened construction timeline ■ Possible to construct directly above live lines without shoring ■ Reduced life cycle costs ■ Existing slab designs can be applied directly ■ High safety standards ■ Uniform quality ■ Improved quality of structures *For more details, please download the PDF or feel free to contact us.

We offer the 'Kaiser BARD slab', which excels in fatigue durability due to the integration effect of truss reinforcement. Pre-stress is introduced using a pre-tension method in the direction perpendicular to the bridge axis, and a half precast PC slab with Kaiser truss reinforcement is installed on top of the girders to enhance the integration with cast-in-place concrete. After arranging the upper reinforcement bars, fresh concrete is poured to form an integrated slab, which serves as both scaffolding and formwork. Please feel free to contact us if you have any inquiries. 【Features】 ■ The Kaiser truss reinforcement serves as a reliable spacer for on-site reinforcement, significantly improving workability and allowing for substantial reductions in construction time and labor. ■ The integration effect of the Kaiser truss reinforcement provides excellent fatigue durability. ■ It can be constructed without support, serving as both formwork and scaffolding, eliminating the need for assembly and disassembly of support structures. *For more details, please download the PDF or feel free to contact us.

This is a shield tunnel intermediate floor slab. It is a rational intermediate floor slab made of high-quality precast components manufactured in a factory, excelling in durability and cost-effectiveness. To enhance the integration with cast-in-place concrete, an HPCa (half precast) intermediate floor slab with Kaiser truss reinforcement is installed. After reinforcing the upper steel bars using the formwork as a combined function, fresh concrete is poured to form an integrated intermediate floor slab. ★Exhibiting at Highway Techno Fair 2024★ 【Features】 ■ The Kaiser truss reinforcement serves as a reliable spacer for on-site reinforcement, significantly improving workability and enabling substantial process shortening and labor saving. ■ The integration effect from the Kaiser truss reinforcement provides excellent fatigue durability. ■ It can be constructed without supports, serving as both formwork and scaffolding, eliminating the need for assembly and disassembly of support structures. *For more details, please download the PDF or contact us.

This is a precast component designed with natural stone materials and fine reliefs on the surface of truss-reinforced HPCa (half precast) panels, taking into consideration the urban landscape. The Kaiser wall, manufactured in a precast factory, is transported to the construction site, erected, lifted, temporarily supported, positioned, fixed, reinforced on-site, formwork constructed, and concrete poured to build the retaining wall.

The "Kaiser Railway Elevated Bridge Slab" is a rational slab that uses high-quality precast (PCa) components manufactured in a factory, allowing for the construction of elevated bridges that excel in durability and cost-effectiveness, and is installed on cast-in-place beams. Since the lower half of the slab cross-section is made of PCa, it can be constructed directly above live lines. Additionally, by casting the upper half of the slab on-site, the structure becomes integrated. The intermediate and cantilever sections are unified, eliminating the need for formwork and shoring. Compared to conventional cast-in-place slabs, it reduces construction noise and material yard requirements, contributing to shortened construction schedules and reduced total costs. Please feel free to contact us if you have any inquiries. 【Features】 ■ Shortened construction schedule ■ Possible to construct directly above live lines without shoring ■ Reduced life cycle costs ■ Existing slab designs can be directly applied ■ High safety ■ Uniform quality ■ Improved quality of structures

The "Kaiser Railway Elevated Bridge Slab" is a rational slab that constructs a durable and economical elevated bridge using high-quality factory-produced precast (PCa) components, which are installed on precast beams.

This is a mid-floor slab for a shield tunnel based on the "Kaiser Railway Viaduct Slab." It is a rational slab made using high-quality precast (PCa) components manufactured in a factory, excelling in durability and cost-effectiveness. To enhance the integration with cast-in-place concrete, a half-precast mid-floor slab with Kaiser truss reinforcement is installed. After reinforcing the upper rebar as a formwork, fresh concrete is poured to form an integrated mid-floor slab. 【Features】 ■ The Kaiser truss reinforcement serves as a reliable spacer for on-site reinforcement, significantly reducing construction time and labor through improved workability. ■ The integration effect from the Kaiser truss reinforcement provides excellent fatigue durability. ■ It can be constructed without supports, serving as both formwork and scaffolding, eliminating the need for assembly and disassembly of support structures.

This is a rational top slab made using high-quality precast components manufactured in the factory, excelling in durability and cost-effectiveness. To enhance the integration with cast-in-place concrete, an HPCa (Half Precast) top slab with Kaiser truss reinforcement is installed. After reinforcing the upper steel bars for use as formwork, fresh concrete is poured to form an integrated top slab. 【Features】 - The Kaiser truss reinforcement serves as a reliable spacer for on-site reinforcement, significantly improving workability and allowing for substantial reductions in construction time and labor. - The integration effect provided by the Kaiser truss reinforcement results in excellent fatigue durability. - It can be constructed without supports, serving as both formwork and scaffolding, eliminating the need for assembly and disassembly of support structures.
