Abstract
In a building, reinforced concrete wall panels are bolted to each other and to the floor and roof to provide the outer shell of the building. At the bolt holes in these wall panels a rigid reinforcing rod framework, which is cast in the concrete panel, provides at least one pair of rods passing respectively on opposite sides of each bolt hole to reinforce the panel there. Certain of the wall panels have window openings for receiving standard size, aluminum frame windows. Others of the wall panels provide doorway openings for receiving standard width doors. Preferably, at each outside corner of the building a special corner wall panel is provided.
Claims12
In a building, a wall structure having a plurality of precast, reinforced concrete wall panels adjoining each other in succession, each of said wall panels having opposite peripheral sides and transverse bolt holes in each of said sides, with the bolt holes in the neighboring sides of adjoining panels registering with each other, and clamping bolt and nut assemblies at the registering bolt holes in adjoining panels for holding said panels together, the improvement wherein said bolt and nut assemblies are operatively coupled to the respective peripheral sides of the panels to apply compression to the concrete in said sides adjacent the respective bolt holes, and further comprising a rigid reinforcing framework embedded in each panel and comprising in each of said opposite peripheral sides of the panel:
- a pair of front and back rigid reinforcing rods embedded in said side of the panel and elongated lengthwise of said side, the rods of each pair passing respectively in front of and behind said bolt holes in that side;
- and means rigidly positioning said rods embedded in the respective sides of said panel to withstand the compression applied to the sides of the panels by the respective bolt and nut assemblies.
In a building, a side wall having a plurality of upstanding, rectangular, precast, reinforced concrete wall panels extending side-by-side in succession, each of said panels having horizontal top and bottom edges, the improvement which comprises
- a rigid reinforcing rod framework embedded in each panel and comprising:
- a first pair of front and back, vertically elongated, rigid rods extending down along the respective panel adjacent one of said side edges;
- a second pair of front and back, vertically elongated, rigid rods extending down along the respective panel adjacent the opposite side edge;
- and upper pair of front and back rigid rods which are horizontally elongated from side to side in the respective panel adjacent said top edge, the front rod of said upper pair extending between and being joined to the respective front rods of said first and second pairs, the back rod of said upper pair extending between and being joined to the respective back rods of said first and second pairs;
- and short rod segments extending from front to back in the respective panel between the front and back rods of each pair at spaced locations on the framework, said short rod segments being joined to and spacing apart the front and back rods of each pair;
- each panel having bolt holes extending horizontally inward from each of said opposite side edges of the panel between the front and back rods of the adjacent vertically elongated pair, each of said bolt holes being accessible at its inner end from the back of the panel, and the bolt holes in the neighboring sides of adjoining panels registering with each other;
- clamping bolts extending through the registering bolt holes in adjoining panels;
- and nuts threaded onto said bolts for holding the adjoining sides of said panels clamped to each other and applying compression to the concrete in said neighboring sides of adjoining panels which is taken up by the corresponding front and back rods embedded in the concrete on either side of each bolt hole.
