<p>The present invention relates to an extension construction method for a concrete building. The present invention is to integrally form beams, connection beams, and a slab on the top of columns in a horizontal line by forming beam frames and connection beam frames between the lower frame and the upper frame of the slab, thereby lowering the entire height of the building, and reducing construction time and the amount of materials required for construction. The extension construction method for concrete building comprises: a column frame forming step (S10); a slab lower frame forming step (S20); a beam frame forming step (S30); a connection beam frame forming step (S40); a slab upper frame forming step (S50); a mold forming step (S60); and a curing step (S70).</p> |
