Bar joist reinforcement apparatus

摘要

A bar joist reinforcement apparatus may include a base assembly adapted to be connected to a lower portion of a bar joist, a top assembly adapted to be connected to a top portion of the bar joist, and an adjustable coupling assembly connected between the base assembly and the top assembly for adjusting the distance separating the base and top assemblies. The apparatus may be used to reinforce a bar joist by inserting the apparatus in between upper and lower portions of a bar joist, adjusting the apparatus so the top and base assemblies come into contact with, press against, and/or brace the upper and lower portions of the bar joist, and connecting the apparatus to the bar joist using bolts and conventional tools instead of welding.

1. An apparatus, comprising:
a base assembly including an inverted u-shaped portion and two substantially flat flanges extending perpendicularly outward therefrom, a plurality of base bolt openings defined in the inverted u-shaped portion, a plurality of base nuts connected to outer surfaces of the inverted u-shaped portion adjacent to the plurality of base bolt openings, and a base elongated rectangular portion extending perpendicularly outward from the inverted u-shaped portion; a top assembly including an elongated u-shaped portion, a plurality of top bolt openings defined in the elongated u-shaped portion, and a plurality of top nuts connected to outer surfaces of the elongated u-shaped portion adjacent to the plurality of top bolt openings, wherein the top assembly includes a top elongated rectangular portion extending perpendicularly outward from the elongated u-shaped portion and a plurality of gussets connected to opposite sides of the top elongated rectangular portion and the elongated u-shaped portion; and an adjustable coupling assembly connected between the base assembly and the top assembly; wherein, when the adjustable coupling assembly is rotated in one direction, the base assembly and top assembly move away from one another and, when the adjustable coupling assembly is rotated in an opposite direction, the base assembly and top assembly move toward one another.
