Plastic deck railing
A deck railing section comprises synthetic posts held spaced from one another by top and bottom rail members. Each of the rail members has a multiple piece construction including first and second interlocking synthetic rail pieces and a metallic reinforcing insert. The insert has holes at post attachment locations along the insert. Each post has screw ports to opposite ends of the post. Rail members are secured to the posts by threaded attachment members passing through the holes in the inserts and into the screw ports of the posts. The first rail pieces are trapped between the posts and the inserts. The second rail pieces lock onto the first rail pieces hiding the reinforcing inserts internally of the rail members.
1. A deck railing section comprising synthetic side by side newel posts held spaced from one another by top and bottom rail members, each of said rail members having a multiple piece construction including first and second interlocking synthetic rail pieces and a metallic reinforcing insert, the reinforcing insert having holes therein at post attachment locations therealong, each post having screw ports to opposite ends thereof, the rail members being secured to the posts by threaded attachment members passing in a vertical direction through the holes in the inserts and into the screw ports of the posts with the first rail pieces being penetrated by the threaded attachment members and thereby trapped between the posts and the inserts, the second rail pieces locking onto the first rail pieces of the rail members biding the reinforcing inserts internally of the rail members.
2. A deck railing section as claimed in claim 1 wherein each rail member has a generally hollow construction with an internal space between the first and second pieces of each rail member, the reinforcing insert having a height to span the internal recess of each rail member.
3. A deck railing section as claimed in claim 2 wherein the first and second pieces of each rail member having interlocking undercut tabs, the reinforcing insert in each rail member applying pressure to enhance the interlocking of the tabs of the first and second pieces of the rail members.
4. A deck railing Section as claimed in claim 1 wherein the holes in the reinforcing inserts are provided in groups of pairs spaced along each insert, each end of each post being provided two of said screw ports, one to each side of each end of each post.
5. A deck railing section as claimed in claim 4 wherein each reinforcing insert has a channel shape which includes a channel base and channel legs, the channel base having a tiered construction including a center tier vertically offset from outer tiers to opposite sides of said center tier, said groups of pairs of holes being provided in the other tiers of the channel base.
6. A deck railing section as claimed in claim 5 including metallic connectors for connecting said deck railing section with another structure, the metallic connectors being provided internally of and hidden within the rail members.
7. A deck railing section as claimed in claim 6 wherein said metallic connectors are L shaped having first and second arms perpendicular to one another, the first arm having a tined construction to interlock with the tiered construction of the channel base of the reinforcing insert.
8. A deck railing section as claimed in claim 7 wherein the second arm of each connector is provided with mechanical fasteners for attachment to a corresponding connector of a further deck railing section to a support for said deck railing section.
9. A deck railing section as claimed in claim 1 wherein each of said posts has an extruded construction, said construction including said screw ports which are an integral part of each of said posts and which are hidden interiorly of each of said posts.
