Precast wall panels and method of erecting a high-rise building using the panels

Abstract

Precast wall systems and methods for constructing a high-rise building using the precast wall system is disclosed. In one embodiment, the system includes a plurality of interconnected precast panels, each having a top end plate, a bottom end plate, a plurality of vertical bars disposed between the end plates and a cementitious material encasing the vertical bars and defining a plurality of sides of the respective panel. A first of the precast panels has a first column member half defining a right side of the first panel, a second of the precast panels has a second column member half defining a left side of the second panel such that, when the right side of the first precast panel and the left side of the second precast panel are disposed horizontally adjacent to each other, the first column member half and the second column member half collectively form a column member.

         13 . A precast wall system, comprising:
 a first plurality of horizontally interconnected precast panels, each precast panel having a top end plate, a bottom end plate, a plurality of vertical bars disposed between the end plates and a cementitious material encasing the vertical bars and defining a plurality of sides of the respective panel,   wherein one of the first plurality of horizontally interconnected precast panels is a corner precast panel that includes a column member having an end partially encased in the corner precast panel and another end extending above the top of the corner precast panel, the column member having a strength to support a gravity column.   
     
     
         14 . A precast wall system as set forth in  claim 13 , wherein the column member has an I-beam shape. 
     
     
         15 . A precast wall system, comprising:
 a transfer member;   a connection plate;   a second plurality of horizontally interconnected precast panels defining a lower tier; and   a first plurality of interconnected precast panels arranged on and vertically adjacent to the second plurality of the interconnected precast panels to define an upper tier,   wherein:   each precast panel has a top end plate, a bottom end plate, a plurality of vertical bars disposed between the end plates and a cementitious material encasing the vertical bars and defining a plurality of sides of the respective panel,   the upper tier precast panels are thinner than the lower tier precast panels,   each precast panel has a plurality of corner edges extending a height of the precast panel and each precast panel further includes a plurality of structural angles, each angle is disposed along a respective one of the corner edges of the precast panel,   the transfer member has a width equal to a change of thickness (Δt) of the lower and upper tier precast panels,   the transfer member is affixed to the structural angle of one of the upper tier precast panels and a portion of the bottom end plate extending from the one upper precast panel, and   the connection plate spans and is affixed to the transfer member and the structural angle of one of the lower precast panels vertically adjacent to the one upper precast panel.
