A first step of coupling the support and the drop beam to each other; Arranging a middle beam before and after the drop beam, and fixing the middle beam to each other with a connecting member; A third step of inserting and inserting a support member into a first insertion hole formed in the support, wherein both ends of the insert support member are exposed to the outside to support the connection member; A fourth step of arranging the posts completed through the first, second, and third steps at predetermined intervals; A fifth step of continuously seating and coupling the slab foams to the slab foam seating portion of the first side portion formed in the drop beam of each post and the second side portion formed of the middle beam; A sixth step of placing concrete on the drop beam, the middle beam, and the slab forms; And The middle beam, the connecting member, and the slab foams combined into one are separated from the cured concrete surface and the drop beam to stop down at a predetermined distance, and then the slab foam, the connecting member, and the middle beam are respectively sequentially. A seventh step of disassembly; Slab construction method of the building made, including. The method of claim 9, wherein the seventh step A second insertion hole is formed at a predetermined interval downward from the first insertion hole of the support, and the insertion support member is removed from the first insertion hole and inserted into the second insertion hole, but both ends of the insertion support member Inserting 7-1 to be exposed to the outside; Step 7-2 of leaving the middle beam and the slab foam positioned in the edge region of the cured concrete away from the concrete surface; A step 7-3 in which the separated middle beam and the slab form are seated on the insertion support member inserted into the second insertion hole while descending at a time; Among the slab forms disposed between the adjacent supports, the slab form coupled to the second side of the middle beam is decoupled, and the slab form released using the spaced-apart space secured while the middle beam and the slab descends is inclined to pull out the slab form. Steps 7-4; A seventh to fifth step of releasing the middle beam after releasing the connection member; Slab construction method of a building, characterized in that further comprises.
