PURPOSE: A sidewalk block for extension is provided to reduce construction errors when multiple main piles are installed by installing a support beam and a slab after wall concrete is placed and cured. CONSTITUTION: A sidewalk block(100) for extension comprises multiple main piles(110), reinforcing bar couplers, wall reinforcing bars, anchor bolt couplers, wall concrete(150), support beams(160), and slabs(170). The main piles are vertically installed on the ground along a road side. The reinforcing bar couplers are coupled to the top ends of the main piles. The wall reinforcing bars are horizontally extended across the main piles and connected to the reinforcing bar couplers. The anchor bolt couplers are vertically protruded from the wall reinforcing bars. The wall concrete is extended across the top ends of the main piles. The support beams are installed on the top of the wall concrete at uniform intervals. Both ends of the slabs are supported to the adjacent support beams. |
