Safety railing for building construction

Abstract

A post support for a safety railing used in building construction comprises a hollow post socket having an open top and a through bore extending horizontally therethrough. An anchor is received within the post socket. There is a bar received through the bore of the post socket. The bar intersects with the anchor and restricts movement of the anchor relative to the post socket.

What is claimed is: 
     
         1 . A post support for a safety railing used in building construction, the post support comprising:
 a hollow post socket having an open top and a through bore extending horizontally therethrough;   an anchor received within the post socket; and   a bar received through the bore of the post socket, the bar intersecting with the anchor and restricting movement of the anchor relative to the post socket.   
     
     
         2 . The post support as claimed in  claim 1  wherein the anchor includes a slot and the bar is received within the slot. 
     
     
         3 . The post support as claimed in  claim 2  further including a rod received within the slot and secured to the anchor, the rod being positioned within the slot adjacent to the bar. 
     
     
         4 . The post support as claimed in  claim 1  wherein the post support includes support members extending downwardly and radially outwardly from the post socket. 
     
     
         5 . The post support as claimed in  claim 1  further including a removable cap which releasably closes the open top of the post socket. 
     
     
         6 . The post support as claimed in  claim 5  wherein the cap has an aperture and an elongate member received through the aperture. 
     
     
         7 . The post support as claimed in  claim 6  wherein the elongate member is flexible and includes burrs which engage a surface of the cap to prevent the elongate member from being uncoupled from the cap. 
     
     
         8 . A safety railing for building construction, the safety railing comprising:
 a plurality of posts, the posts each having a post body and a male threaded portion on an end of the post body; and   a plurality of post supports, the post supports each having:
 a hollow post socket having an open top and a through bore extending horizontally therethrough, 
 an anchor received within the post socket, the anchor having a slot and a rod received within the slot, the rod being secured to the anchor, and 
 a bar received through the bore of the post socket, the bar intersecting the slot of the anchor adjacent to the rod to restrict movement of the anchor relative to the post socket; 
   wherein said male threaded portions engage with corresponding ones of said rods to couple the posts to the post supports.   
     
     
         9 . The safety railing as claimed in  claim 8  wherein the post includes a D-ring connected to the post body and spaced-apart from the male threaded portion. 
     
     
         10 . The safety railing as claimed in  claim 8  wherein the post includes a spacer disposed between the D-ring and the male threaded portion. 
     
     
         11 . The safety railing as claimed in  claim 8  wherein the post includes a support bracket for supporting a rail, the support bracket having a first support member connected to the post body and a second support member extending upwardly from the first support member. 
     
     
         12 . The safety railing as claimed in  claim 11  wherein the post includes a collar with a cable extending therefrom, the cable having a hook on an end thereof which is securable to the support bracket. 
     
     
         13 . The safety railing as claimed in  claim 8  wherein the post includes a tab with an aperture for receiving a fastener. 
     
     
         14 . A method of installing a safety railing in a building under construction, the method comprising:
 inserting an anchor into a post socket of a post support;   inserting a bar horizontally through the post socket so that the bar intersects the anchor and restricts movement of the anchor relative to the post socket;   mounting the post support on a concrete floor formwork;   casting concrete to form a concrete floor on the concrete floor formwork and thereby embedding the post support in the concrete floor;   inserting a lower end of a post into the post socket and engaging a male threaded portion of the post with the anchor of the post support to support the post above the concrete floor; and   supporting a rail on the post.   
     
     
         15 . The method as claimed in  claim 14  further including covering the post socket before casting the concrete to prevent concrete from entering the post socket and uncovering the post socket after casting the concrete to allow insertion of the post into the post socket. 
     
     
         16 . The method as claimed in  claim 14  wherein mounting the post support on the concrete floor formwork includes inserting fasteners through apertures in respective support members extending downwardly and radially outwardly from the post socket. 
     
     
         17 . The method as claimed in  claim 14  wherein supporting the rail on the post includes placing the rail on a support bracket of the post and securing the rail to a tab extending from the post. 
     
     
         18 . The method as claimed in  claim 14  wherein supporting the rail on the post includes placing the rail on a support bracket of the post, winding a cable extending from the post around the rail, and securing a hook on an end of the cable to the support bracket. 
     
     
         19 . The method as claimed in  claim 14  further including removing the post from the post socket and applying a layer of finish concrete onto the concrete floor to fill the post socket with the finish concrete. 
     
     
         20 . The method as claimed in  claim 14  further including removing the concrete floor formwork from the concrete floor after the concrete floor has set, grinding the underside of the concrete floor and applying a finish layer to the underside of the concrete floor.
