RESTRUCTION STEEL NETWORK ASSEMBLY FOR FLAT STRUCTURE AND ESTABLISHING FLAT STRUCTURE USING THE ASSEMBLY}

The present invention relates to a reinforcing structure for plate structures such as walls and slabs in reinforced concrete structures, and more particularly, to a reinforcing steel plate assembly for reinforcing plate structures and reinforcing methods using the same while providing the same structural characteristics and reducing the amount of rebars. will be.

In general, the reinforced concrete structure is grounded, the reinforced structure is installed on the ground, the mold is installed at a position spaced apart from the reinforced structure, and the concrete is put into the mold to remove the mold. It is building a building. Reinforcement structures are inserted into the reinforcement of the building to be constructed as reinforced concrete structure, and the workers are bound by hand one by one at the position to install the walls, slabs, columns, etc. of the building.

On the other hand, for reinforcing structures used in pillars, walls, slabs, etc. of buildings, the reinforcing bars specified in KS standards are used. SD40 bar reinforcement is applied to the structural calculation with the elastic strength of 400N / mm2 to calculate the reinforcement amount AS400. do. In addition, conventionally, as the reinforcing bar reinforcement to a wall or slab, reinforcing bars having a diameter of about 10 mm to 14 mm are mainly used.

In case of reinforcing steel structures used for walls or slabs directly in the field, it is necessary to use reinforcing bars with a diameter of 10mm or more, and it takes a long time for the reinforcement work to produce the steel structures, thereby increasing labor costs. have.

Therefore, when using the pre-manufactured standard rebar network, it is possible to use the reinforcing bar of 10mm or less, and it can reduce the construction cost by providing about 20 ~ 30% of the rebar while providing the same characteristics. There is an advantage in design.
