Generally, a flat plate slab is a building structure in which the floor is composed of only slab without a beam, and the load of the slab is directly transmitted to the column. Since stress is concentrated around the column of the slab, breakage due to punching shear tends to occur.
In order to prevent such shear failure, the conventional flat plate slab reinforces the shear resistance of the adjacent portion of the slab to the column, and a representative example thereof is a slab laying structure having a shear reinforcement.
This struc- ture structure is described in Registration No. 20-447972 (shear stiffener of a concrete unglazed plate structure) registered as a utility model in the Korean Intellectual Property Office, and as shown by

Further, since the unit shear reinforcements are short in length, the other ends of the shear reinforcement are hardly sagged with respect to one end. Therefore, the pitch change of the concave and convex portions due to sagging can be prevented and the shear resistance of the slab can be maintained uniform, It is easy to store and transport.
In particular, even if the length of the shear reinforcement is short, the length of the shear reinforcement can be freely extended as much as desired through the fastening means, so that the length can be easily changed to a desired length at the time of construction.
Further, since the entire shear reinforcement used in the slab reinforcement structure can be modularized into a single unit through the station, the workability of the shear reinforcement can be further improved.
