The present invention has been made to a vertical extension to the upper part of the slab (S) in a building having a wall (W) provided in the lower slab (S) and the slab (S) of the uppermost layer,
Of the wall (W) the corner angle (CA), which is installed at the top and the slab (S) bottom; The slab (S) the base plate (BP) which is installed thereon; Is installed at the bottom of column (C) and said columns (C) with a steel end pole by combination of the landing plate (LP) shaped to correspond to the base plate (BP) which is installed on an upper part of the base plate (BP) unit ( CC); The corner angle (CA) and the base plate (BP) and perpendicular to the bolt (VB) for connecting the landing plate (LP); Doedoe configuration including,; and the horizontal bolt (HB) with which a connection between the corner angle (CA) between the opposite wall (W)
The vertical bolt (VB) and the horizontal bolt (HB) is installed in a pre-drilled hole in said slab (S) and the wall (W), respectively,
After the base plate (BP) is installed provides a pillar fitting structure for vertical enlargement characterized in that the installation pole unit (CC) is lifting.
In addition to installing the pole mounting structure for the vertical expansion,
(1) boring step of boring a hole in said slab (S) and the wall (W); (2) the corner angle installation step of mounting the wall (W) and the top of said slab (S) of the corner angle (CA) to the lower and install the vertical bolt (VB) and the horizontal bolt (HB); (3) the mounting base plate to install the base plate (BP) on top of the slab (S); (4) Column unit installation step of installing and lifting the pole unit (CC) to the landing plate (LP) is in close contact with the base plate (BP) thereon; It provides a method of installing pole fitting structure for a vertical extension being configured, including; and, (5) a nut fastening step for fastening the nut (N) at the top of the vertical bolt (VB).
