In a steel building with concrete slabs, it is common to break concrete slabs when attaching reinforcing members and join the floor beams to the reinforcing material. However, since the destruction work of the concrete slab generates noise and vibration, it is often difficult to perform reinforcement work while using the building. Therefore, without breaking the concrete slab, we developed a method to attach reinforcing members to steel beam columns, and carried out reinforcement work. As a result, we were able to achieve results such as reduction of construction scope, cost reduction of temporary expenses, shortening of construction period, etc.
