A flat roof support structure includes a plurality of vertical columns, an elongated generally horizontally oriented beam associated with and positioned atop each vertical column, and attachment structure fixing the upper end of each vertical column to a mounting area of the associated elongated beam. The attachment structure includes U-shaped attachment members affixed to opposed sides of the vertical columns at the upper end of each column with the attachment members opening in an outwardly directed orientation parallel to the associated elongated beam. A pair of attachment plates is fixed to opposed sides of each elongated beam in the mounting area. The attachment plates extend downwardly below a lower surface of the elongated beam a distance equal to a portion of the U-shaped attachment members so as to overlap the portion. Attachment devices fix the attachment plates to the U-shaped attachment members and are assembled on-site. |
