Stick Columns Settlement For Free

Chip off the top surface of the old column in such a way the steel rods are visible for six inches. WELD NEW RODS TO THE OLDER RODS. Apply NITOBOND to the old surface of concrete and put form work for six inches and pour fresh concrete. ... Pour cement slurry and lay first lift of concrete.

Mark the column positions, get the reinforcing details from structural engg. Drill down and expose the reinforcing bars and weld new reinforcing bars for new columns. Build a rind beam on the periphery of the house on top of the slab with a gap between the new beams and the existing slab of 25mm.

A tied column is one in which smaller diameter transverse bars, commonly known as ties, attach the reinforcing bars at regular intervals. The major purpose of the ties is to maintain the longitudinal bars vertical while they are built. It also contributes to the column's buckling resistance.

Jacketing is a method of structural retrofitting and strengthening. It's commonly used on columns, and in combination with walls, beam sides & bottoms. As the name suggests, jacketing involves creating materials to the spec of the original column then encasing them around like a protective jacket.

The procedure of adding reinforced concrete columns is by marking out all the points to add columns. The walls and roofs are supported using props and bracing. The columns should be place at all building corners and any load bearing walls intersections. The wall is cut carefully up to the beam level.

Yes, make sure the pillars are big enough to carry the extraload. And also if the foundation is affected, try pinning it, in all cases, make sure the rcc bars are very strong and at least 12mm, or 16mm preferable with three and above netting and the columns must cast with very rich concrete.

Column ties are used in columns to maintain the vertical position of the longitudinal bars and to provide some resistance against buckling. They are also used to confine the concrete core and enhance the ductility and seismic performance of the column.
