Document Type and Number:
Japanese Patent JP2019138017
Kind Code:
A
Abstract:
To provide a prestress introduction method and a prestress introduction structure capable of reducing a construction cost.SOLUTION: According to this prestress introduction method, a prestress introduction structure 100 is obtained by introducing prestress to a concrete structure C by introducing a tension force to a screw-knotted reinforcement 10 embedded in the concrete structure C. That is, apart from the screw-knotted reinforcement 10 embedded as a reinforcing member in the concrete structure C, it is possible to introduce prestress to the concrete structure C by suppressing the construction cost by a comparatively simple work by a simplified construction without performing large-scale work such as placing a PC steel material for introducing prestress.SELECTED DRAWING: Figure 1
