US 5,123,220 A · Column assembly

Abstract

A column assembly having a plurality of floor-height columns which are erected vertically, one on top of the other, to define the floors of the building structure to be constructed. Each column comprises a plurality of reinforcement rods which are embedded in the column and extend outwardly from the ends thereof. The rods are cut at precisely equal lengths to extend precisely equal distances from each end of the column. Each rod is threaded in a precise manner with the thread beginning at the same orientation for each rod such that when the columns are stacked end-to-end, the rods are in perfect axial alignment with the thread of one rod continuously leading into the thread of the contiguous rod to which it is aligned. A threaded sleeve is threaded onto the rods extending from the lower end of the upper column and, after stacking of the upper column end-to-end onto a lower column, the threaded sleeve may be threaded onto the axially aligned and contiguous rods extending from the lower column. A rigid mechanical connection is therefore made between adjacent columns sufficient to support the columns vertically without additional shoring.

Dependent claims

A column assembly, comprising in combination:

a first column having a first end and a second end;
at least one first threaded rod extending from said second end of said first column;
a second column having a first end and a second end;
at least one second threaded rod extending from said first end of said second column in axial and contiguous alignment with said first threaded rod defining a space between said second end of said first column and said first end of said second column;
and
a threaded sleeve threadably interconnecting said first threaded rod and said second threaded rod.

A column assembly, comprising in combination:

a first column having a first end and a second end;
at least one first threaded rod extending from said second end of said first column;
a second column having a first end and a second end;
at least one second threaded rod extending from said first end of said second column in axial and contiguous alignment with said first threaded rod defining a space between said second end of said first column and said first end of said second column;
a threaded sleeve threadably interconnecting said first threaded rod and said second threaded rod;
wherein a plurality of said first threaded rods extend from said second end of said first column, wherein a corresponding plurality of said second threaded rods extend from said first end of said second column in axial and contiguous alignment with respective said first threaded rods, and wherein a corresponding plurality of said threaded sleeves threadably interconnect respective said first threaded rods and said second threaded rods, and wherein said first threaded rods extend from said second end of said first column equal distances and wherein said second threaded rods extend from said first end of said second column equal distances, and wherein said threaded sleeves comprise a length less than said distance said first threaded rods extend from said second end of said first column or said distance that said second threaded rods extend from said first end of said second column, thereby allowing said threaded sleeves to be threaded fully onto said first threaded rods or said second threaded rods prior to said rods being positioned in axial and contiguous alignment;
grout means filling said space between said second end of said first column and said first end of said second column;
and
wherein said first column further comprises a capital positioned at said second end of said first column, said capital having a surface area greater than the cross-sectional area of said first column defining a ledge for supporting a bearing beam when said columns are positioned vertically, said capital including a plurality of apertures through which extend respective said first threaded ends and wherein said threaded sleeves engage said capital when said threaded sleeves are threaded from said second threaded rods onto said first threaded rods.
