Title:
壁高欄の補強方法及び補強構造
Document Type and Number:
Japanese Patent JP7222824
Kind Code:
B2
Abstract:
To perform reinforcement by making vertical compressive stress act on a lower end part of a wall balustrade made from concrete.SOLUTION: A tension material insertion hole 12 reaching the inside of a wall balustrade 1 is drilled upward from an underside of a concrete slab 2, and an anchorage part formation hole 15 communicating with an upper part of the tension material insertion hole is cut from a side surface of the wall balustrade. A tension material 11 is inserted into the tension material insertion hole 12 and the tension material insertion hole is filled with shrinkage-compensating mortar 14 from the anchorage part formation hole, to anchor an upper end part of the tension material to the wall balustrade. A lower end part of the tension material is tensed by the underside of the concrete slab and the tension material in a state in which tension force is introduced is anchored to the concrete slab and thickness increased concrete 13 placed so as to be integrated with the concrete slab. The thickness increased concrete 13 is placed so as to cover a lower part of an external surface of the wall balustrade from the underside of the concrete slab and reinforces the concrete slab's tip and the wall balustrade's lower part integrally with the concrete slab and the wall balustrade.SELECTED DRAWING: Figure 2
