SAFETY RAILING FOR BUILDING CONSTRUCTION
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.
The present invention relates to a safety railing and, in particular, to a safety railing for building construction.
BACKGROUND OF THE INVENTIONUnited States Patent Application Publication Number 2007/0137135, which was published on Jun. 21, 2007 in the name of Shymkowich, discloses a method of installing a safety railing in a building under construction. The method comprises providing post supports having open-topped post sockets on socket supports, mounting the post sockets on a concrete floor formwork with the post sockets spaced above the concrete floor formwork by the socket supports, casting concrete to form a concrete floor on the concrete floor formwork and thereby embedding the post supports in the concrete floor with the concrete extending beneath the post sockets. The lower ends of posts are then inserted into the post sockets to support the posts above the concrete floor and rails are supported on the posts.
SUMMARY OF THE INVENTIONThere is provided a post support for a safety railing used in building construction comprising 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.
The anchor may include a slot and the bar may be received within the slot. There may be a rod received within the slot and secured to the anchor. The rod may be positioned within the slot adjacent to the bar. The post support may include support members extending downwardly and radially outwardly from the post socket. The post support may have a removable cap which releasably closes the open top of the post socket. The cap may have an aperture and an elongate member received through the aperture. The elongate member may be flexible and may include burrs which engage a surface of the cap to prevent the elongate member from being uncoupled from the cap.
There is also provided a safety railing for building construction comprising a plurality of posts and a plurality of post supports. The posts each have a post body and a male threaded portion on an end of the post body. The post supports each have a hollow post socket having an open top and a through bore extending horizontally therethrough. There is an anchor received within the post socket. The anchor has a slot and a rod received within the slot which is secured to the anchor. There is a bar received through the bore of the post socket. The bar intersects the slot of the anchor adjacent to the rod to restrict movement of the anchor relative to the post socket. The male threaded portions engage with corresponding ones of the rods to couple the posts to the post supports.
The post may include a D-ring connected to the post body and spaced-apart from the male threaded portion. There may be a spacer disposed between the D-ring and the male threaded portion. The post may include a support bracket for supporting a rail. The support bracket may have a first support member connected to the post body and a second support member extending upwardly from the first support member. The post may include a collar with a cable extending therefrom. The cable may have a hook on an end thereof which is securable to the support bracket. The post may include a tab with an aperture for receiving a fastener.
There is further provided a method of installing a safety railing in a building under construction comprising inserting an anchor into a post socket of a post support. A bar is inserted horizontally through the post socket so that the bar intersects the anchor and restricts movement of the anchor relative to the post socket. The post supports are mounted on a concrete floor formwork. Concrete is cast to form a concrete floor on the concrete floor formwork, thereby embedding the post support in the concrete floor. A lower end of a post is inserted into the post socket and a male threaded portion of the post is engaged with the anchor of the post support to support the post above the concrete floor. A rail is supported on the post.
The post socket may be covered before casting the concrete to prevent concrete from entering the post socket. The post socket may be uncovered after casting the concrete to allow insertion of the post into the post socket. The post support may be mounted on the concrete floor formwork by inserting fasteners through apertures in respective support members extending downwardly and radially outwardly from the post socket.
The rail may be supported on the post by placing the rail on a support bracket of the post and securing the rail to a tab extending from the post. Alternatively, the rail may be supported on the post by 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.
The post may be removed from the post socket and a layer of finish concrete may be applied onto the concrete floor to fill the post socket with the finish concrete. The concrete floor formwork may be removed from the concrete floor after the concrete floor has set. The underside of the concrete floor may be ground and a finish layer may be applied to the underside of the concrete floor.
The invention will be more readily understood from the following description of the embodiments thereof given, by way of example only, with reference to the accompanying drawings, in which:
Referring to the drawings and first to
Referring now to
The post support 14a may include a removable lid 32 for releasably closing the open top 24 of the post socket 22. As best shown in
Referring now to
The post 16a includes tabs, for example, tabs 70a, 70b and 70c spaced-apart along the body 17. The tabs 70a, 70b and 70c are rectangular in this example and extend tangentially from the body 17. The tabs are spaced-apart along the body 17 such that the tabs 70a and 70b are positioned near the support brackets 64a and 64b respectively, and the tab 70c is positioned near the D-ring 60. The tabs 70a, 70b and 70c include respective apertures 72a, 72b and 72c. As best shown in
The rails 18c and 18d may be supported on the support bracket 64b in a similar manner as described above for the support bracket 64a and as shown in
Referring now to
The post supports are mounted so that they are spaced-apart from one another on a concrete floor formwork 100 as shown for one of the post supports 14a in
The lid 32, shown in
When the safety railing 10 is no longer required, the rails 18a, 18b, 18c and 18d, the kick rails 20a and 20b, and the posts 16a and 16b are removed. A finish layer 110 of concrete is then applied to the top surface 108 to fill the interior of the post sockets and conceal the post supports embedded in the concrete floor 12 as shown in
The heights of the post supports determine the thickness of the concrete floor. The post supports may accordingly be produced in different sizes to cast floors of corresponding different thicknesses.
It will be understood by a person skilled in the art that many of the details provided above are by way of example only, and are not intended to limit the scope of the invention which is to be determined with reference to the following claims.
