Abstract
The present invention relates to a temporary rail structure that includes a series of vertical posts that are interconnected by horizontally extending side rails. Each post is designed to clamp around the top portion of a band that extends around floor joist that support a sub-floor thereabove. Around the entire floor structure is formed a series of spaced apart openings, each opening cut in the sub-floor adjacent the inside of the band. Each temporary post includes a U-shaped yoke that includes one leg that is inserted downwardly through the opening formed in the sub-floor such that this leg extends adjacent the inside of the band. A screw-type tightener is secured to another leg of the yoke and is screwed from the outside so as to tighten down on the band.
Claims7
A portable and temporary railing structure for surrounding a floor of a residential structure where the floor includes underlying floor joists, a band surrounding the floor joists, and a sub-floor disposed over the floor joists and wherein the sub-floor includes a series of spaced apart openings formed through the sub-floor adjacent the inside of the band, and wherein the temporary railing structure includes a series of temporary posts secured to the band and spaced around the outside edge of the floor area and wherein the temporary posts receive and support a series of side railings that extend between the respective posts;
- and wherein each temporary support posts includes an elongated member having an inverted U-shaped band attachment for attaching the temporary posts to the band and wherein the U-shaped band attachment includes a first outside leg that extends along the outside of the band, a sub-floor penetrator that extends downwardly through the opening within the sub-floor and rests adjacent the inside of the band, and a bolt-type fastener threaded in the first outside leg and movable therein to engage the band so as to secure the entire U-shaped band attachment to the band;
- and wherein there is provided rail holding means secured on the elongated member for receiving and holding side rails.
A method of erecting and disassembling a temporary rail structure around the floor area of a building under construction comprising the steps of:
- a) cutting a series of holes in a sub-floor structure adjacent the inside of a surrounding band that surrounds the floor and floor joists supporting the floor;
- b) inserting one leg of a U-shaped yoke through a respective hole in the sub-floor and clamping the U-shaped yoke to a top portion of the surrounding band such that the one leg of the U-shaped yoke is held adjacent the inside of the band while extending through the hole in the sub-floor;
- c) extending a post upward from the U-shaped yoke to form a temporary post and continuing to add such posts around the floor by the same method;
- d) connecting horizontal side rails between respective posts to form a temporary railing structure around the floor of the building under construction;
- and
- e) dismounting the entire temporary rail structure by removing the rails and then unclamping the U-shaped yokes from the top of the band and pulling the U-shaped yoke upwardly such that the one leg of the yoke is pulled from the opening within the sub-floor.
