日本橋梁工業 List of Products and Services

When establishing new access roads or widening existing roads, three-dimensional movements occur in the vertical direction, along the bridge axis, and perpendicular to the bridge axis due to differences in the positions of bridge piers, abutments, and the structure of the deck. The product that can accommodate these three-dimensional movements is the expansion joint, specifically the Diah-Free Joint (rubber type) vertical joint. The K-40T, K-50T, and K-80T models effectively follow the unique three-dimensional movements of the vertical joint. The K-210T, K-240T, and K-330T models can handle large displacement amounts. We offer a variety of vertical joint net pin types. For more details, please contact us or refer to the catalog.

The "K-40T" is a diamond-free joint developed by our company, which is an expert in vertical joints. It features a separation structure consisting of a receiving base installed on the floor slab, a receiving plate placed on top of the receiving base, and a surface rubber with numerous diamond-shaped holes. Despite being separate components, they function as a cohesive unit, demonstrating excellent performance. It also closely follows the unique three-dimensional movements of vertical joints, making it widely used on many highways, bridges, and elevated roads. 【Features】 ■ Protects the floor slab ■ Comfortable driving ■ Safe driving ■ Environmentally friendly ■ Cost-saving *For more details, please download the PDF or feel free to contact us.

The "K-50T" is a diamond-free joint developed by our company, which is an expert in vertical joints, specifically for vertical joints. Since the surface rubber, receiving plate, and receiving base have a separated structure, wear of the surface rubber does not expose the steel plate that causes slipping, allowing for safe travel. Additionally, the surface rubber absorbs expansion and contraction through the elastic deformation of the diamond-shaped holes, keeping the surface of the joint consistently flat, resulting in reduced noise during travel and a comfortable ride. 【Features】 ■ Protects the floor slab ■ Comfortable travel ■ Safe travel ■ Environmentally friendly ■ Cost-saving *For more details, please download the PDF or feel free to contact us.

The "K-80T" is a diamond-free joint developed by our company, which is an expert in vertical joints. By adopting a high-nut type anchor bolt, it eliminates the need to chip concrete during repairs, thereby preventing noise and debris waste, and reducing construction time. It also closely follows the three-dimensional movements unique to vertical joints, making it suitable for use on many highways, bridges, and elevated roads. 【Features】 ■ Protects the deck ■ Comfortable driving ■ Safe driving ■ Environmentally friendly ■ Cost-saving *For more details, please download the PDF or feel free to contact us.

The "K-210T" is a diamond-free joint designed for vertical joints that can accommodate large displacement amounts caused by longer span lengths. The surface rubber has sufficient thickness, and the load-bearing plate is coated with rubber on a steel plate, which helps to mitigate impact loads and reduces the effects on the floor slab. Additionally, the surface rubber absorbs expansion and contraction through the elastic deformation of diamond-shaped holes, keeping the joint surface consistently flat, resulting in reduced noise during travel and a more comfortable ride. 【Features】 ■ Protects the floor slab ■ Comfortable travel ■ Safe travel ■ Environmentally friendly ■ Cost-saving *For more details, please download the PDF or feel free to contact us.

The "K-240T" is a vertical joint designed for accommodating large displacements caused by longer span lengths. By adopting a high-nut type anchor bolt, it eliminates the need to chip away concrete during repairs, thereby preventing noise and debris waste, and reducing construction time. Additionally, the reduction in time also helps minimize exhaust emissions caused by traffic congestion, preserving the living environment in urban areas and the natural environment in suburban areas. 【Features】 ■ Protects the floor slab ■ Comfortable driving ■ Safe driving ■ Environmentally friendly ■ Cost-saving *For more details, please download the PDF or feel free to contact us.

The "K-330T" is a diamond-free joint designed for vertical joints that can accommodate large displacements caused by longer span lengths. With repairs that do not require chiseling, it can extend the lifespan of bridges without damaging the deck and reduce maintenance costs. Additionally, it can be repaired in a short time, which helps reduce economic losses due to traffic congestion.
