The present invention relates to a slab structure for a building and a construction method of a slab structure for a building. The slab structure for a building comprises: a base plate that is a concrete plate placed horizontally and which has multiple front and rear side connection grooves formed at constant intervals from side to side on each edge part of the upper side of the front and rear sides thereof; multiple first lower part steel bars that are buried at constant intervals from side to side in the horizontal direction from the front side to the rear side inside the base plate and whose end parts of the front and rear sides are exposed through the front and rear side connection grooves to the outside of the front and rear sides of the base plate ; multiple second lower part steel bars that are buried at constant intervals front and rear in the horizontal direction from the left side to the right side inside the base plate and whose end parts of the front and rear sides are exposed through the front and rear side connection grooves to the outside of the left and right sides of the base plate thereof; multiple thrust steel bars that are welded along the upper side of the second lower part steel bars and which have the lower parts buried in the base plate; multiple second steel bars that are welded along the upper side of each thrust steel bars and which have lengths corresponding to the lengths of the second lower part steel bars; and multiple first upper part steel bars that are welded along the upper side of the second upper steel bars at constant intervals from side to side in the front and rear horizontal direction and which have lengths corresponding to the lengths of the first lower part steel bars. The base plate has the front and rear sides constructed to be contacted with the front and rear sides of another base plate, thereby connecting the front and rear connection grooves of the base plates from each other and forming a connection space. The end parts of the front, rear and both sides of the first lower part steel bar which are exposed through the front and rear side connection grooves are closely overlapped inside the connection space, and connected or welded through couplers from each other. |
