ポストヘッドバー工法研究会 List of Products and Services

The Post-Head-bar method involves drilling holes in the surface of existing structures using a PHb drill, filling those holes with a special mortar, and then inserting a post-installed plate-type shear reinforcement bar called "Post-Head-bar" to integrate it with the reinforced structure, thereby improving the shear capacity of the member. This innovative seismic reinforcement method makes it possible to easily and economically reinforce the shear capacity of existing structures, which has been considered difficult until now. 【Features】 - Enables shear reinforcement without encroaching on the internal cross-section - Can significantly increase shear capacity while maintaining constant bending strength - Can be constructed using a lightweight, compact dedicated drill, making it feasible in narrow spaces - Eliminates the risk of damage or cutting of rebar due to the use of a dedicated drill - Allows for short construction periods and low costs since excavation of the backfill ground is unnecessary For more details, please contact us or download the catalog.
