Abstract
A wall includes a central hub having an axis extending in a longitudinal direction and three circumferentially spaced walls extending radially from the central hub. Each of the walls is made of cast concrete reinforced with a rebar cage having a plurality of longitudinally spaced pairs of parallel rebars extending radially from the central hub to an end rebar that extends perpendicularly relative to the parallel rebars. Each end rebar is connected to radially outer ends of one of the pairs of parallel rebars. A seawall comprises a plurality of the walls connected together end-to-end with a cable, and connecting plates fastened to adjacent sections. A form for manufacturing the wall encloses connected rebars and is filled with concrete.
Claims6
A form for manufacturing a wall comprising:
- a base including a planar plate that defines a plurality of holes;
- a plurality of V-shaped walls attached at a lower end of the walls to the base, the walls being joined together to define a hub-forming space;
- a plurality of end walls each being secured to radially outer ends of two adjacent V-shaped walls with a plurality of releasable fasteners;
- a top plate attached to a top end of the V-shaped walls;
- a first tube locating protrusion provided on the base and a second tube locating protrusion provided on a lower surface of the top plate, wherein the first and second tube locating protrusions are adapted to retain a pipe inside the hub forming space;
- and
- a plurality of spacers assembled between V-shaped walls in alignment with two openings defined by the adjacent V-shaped sidewalls;
- and
- a plurality of fasteners that each secure two of the V-shaped walls to one of the spacers.
