Concrete panel corner connection
Two building panels are connected through a column. One panel is bolted to the column, for example by way of fasteners passing through holes in a rib of the panel into threaded inserts in the column. A second panel is also bolted to the column, for example to threaded inserts open to another face of the column. Further panels in an upper or lower story of a building may be connected to the same column such that vertically stacked panels are connected together. In another connection, one end rib of a panel is made to receive a second panel. The second panel can be attached to the end rib of the first panel to make a corner.
1. A wall system comprising,
a) a first concrete wall panel having a first slab and a first end rib connected to the first slab, the first end rib and the first slab oriented generally vertically;
b) a second concrete wall panel having a second slab and a second end rib connected to the second slab, the second end rib and the second slab oriented generally vertically;
wherein each of the first and second wall panels has a first layer of insulation between the first slab and the first end rib, and between the second slab and the second end rib, respectively,
and wherein each of the first and second end ribs has a plurality of end rib holes;
c) a column having at least two sides, a plurality of holes, a second layer of insulation recessed into parts of the two sides of the column, the second layer of insulation abutting the first layer of insulation of each of the first and second wall panels, the second layer of insulation extending continuously from the first layer of insulation of the first wall panel to the first layer of insulation of the second wall panel and wherein each side of the two sides of the column has at least two holes corresponding in location to two of the end rib holes of one of the first and second wall panels; and,
d) fasteners passing through the end rib holes of each of the first and second wall panels and secured to the column such that one of the first and second wall panels is secured to each of two sides of the column.
2. The wall system of claim 1 having a third wall panel adapted to be mounted above the first or second wall panel, wherein the column extends above the top of the first and second wall panels and the third wall panel is fastened to the column.
3. The wall system of claim 1 wherein each of the first and second wall panels has at least four end rib holes spaced at the same elevations in both wall panels.
4. The wall system of claim 1 wherein the wall panels further comprise, vertical channels in the first end rib and the second end rib, the vertical channel and a face of the column forming a space; and a plate configured to fit into the space.
5. The wall system of claim 1 further comprising a reinforcing bar in each of the first and second end ribs, the reinforcing bar configured and located to surround the end rib holes.
6. The wall system of claim 1 wherein the holes of the column have threaded inserts cast in place.
7. The wall system of claim 1 , wherein the second layer of insulation terminates at the first layer of insulation of each of the first and second wall panels.
