Method of assembling a guard rail
View Patent ↗A guard rail system fabricated from standard-sized components, preferably extruded, comprises balusters fastened to a lower rail and to an upper retainer at fixed intervals. The balusters are provided with central bores for receiving fasteners such as screws through predrilled holes in the upper retainer and lower rail. A hand rail is slip-fitted over the upper retainer in locking relation, to provide integrated guard rail sections. Guard rail sections so assembled are fastened to end posts, preferably using mounting brackets having a flanged arm which nests in grooves or recesses in the upper retainer and lower rail to provide a safe, secure and aesthetically appealing guard rail.
1. A method of assembling a guard rail, comprising the steps of:
a. pre-drilling a top retainer and a bottom rail for attachment to a plurality of hollow balusters, the top retainer having an exterior surface having a pair of opposed channels and each baluster comprising a plurality of inner webs affixed to a wall of the baluster and to a bore for a fastener disposed within the baluster wall,
b. disposing fasteners through the holes into the bores to affix the balusters between the top retainer and bottom rail,
c. sliding a hand rail having an internal surface having a pair of projections complementary to the channels over the upper retainer to engage the projections in the channels, and
d. affixing the top retainer and the bottom rail to posts.
2. The method of claim 1 wherein the hand rail comprises a bearing plate supported by an upper surface of the upper retainer.
3. The method of claim 1 including, before step a., the step of extruding the top retainer, bottom rail, balusters and hand rail.
4. The method of claim 3 wherein each post is hollow and including the steps of anchoring a structural member and disposing the post over a structural member.
