Description
- This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/641,385, filed on Jan. 4, 2005, the entire contents of which are incorporated herein by reference.
- The present invention relates to the field of building construction and, more particularly, to the field of temporary guardrail systems for use during construction, and related methods.
- During construction of buildings, both commercial and residential, there has been a problem in providing temporary guardrails adjacent to roof edges, decks, balconies, and even elevated floors prior to the construction of exterior walls.
- Temporary guardrails may be constructed adjacent a rooftop with materials commonly found on a construction site, such as excess lumber, for example. A platform is typically built adjacent the edge of the rooftop, and is braced against a wall supporting the rooftop. Spaced-apart guardrail posts are connected to the platform and extend upwardly therefrom, and rails are extended between the guardrail posts to form a barrier adjacent to the edge of the rooftop. The rails may also be provided by excess lumber found on a construction site. A skid-guard, or kickplate, may be connected between the guardrail posts to provide a barrier adjacent the edge of the roof.
- Although this type of guardrail system may be effective, installation may be expensive, time inefficient, and itself hazardous. More specifically, the guardrail system is generally installed after roof members have been elevated and connected to top portions of support walls. In other words, installation of the guardrail system is performed at, or near, the elevation of the rooftop, before fall protection is provided.
- One type of temporary guardrail system using cables is disclosed in U.S. Pat. No. 6,270,057 to Highley et al. The Highley et al. patent discloses a temporary guardrail system including a plurality of guardrail posts that are fastened to a perimeter frame by bolting a corresponding plurality of securement plates to a back surface of the perimeter frame. Each of the guardrail posts comprises a plurality of apertures formed in the lower portion, the medial portion and the upper portion. A plurality of cables pass through the apertures between each of the guardrail posts. The apertures are spaced apart so that the cable may be positioned at varying heights. Installation of this guardrail system, however, may be quite time consuming.
- One example of a guardrail system for a pitched roof is disclosed in U.S. Pat. No. 5,711,398 to Bartholomew. The guardrail system includes a plurality of spaced apart rail support assemblies aligned along an edge of a pitched roof, and a plurality of rails extending between the support assemblies. Each of the rail support assemblies includes a hinged base that is anchored into the roof with a hook so that the base may be positioned on the rooftop.
- Problems with exposed elevated areas of construction still exist. In fact, these problems are of such a serious nature that the Occupational Hazards Safety Act (OSHA) agency has promulgated regulations to require temporary railings on open elevated building structures that are capable of withstanding at least two hundred pounds of pressure without failing.
- In view of the foregoing background, it is therefore an object of the present invention to provide a temporary guardrail system for use on construction sites that can be efficiently installed.
- This and other objects, features, and advantages in accordance with the present invention are provided by a guardrail system comprising a plurality of posts and a rail member detachably connected to and extending between the plurality of posts. Each of the plurality of posts may comprise a first post member and a second post member that slidably engages the first post member.
- More particularly, the second post member may comprise a first cable connector connected to a lower portion thereof. The second post member may also comprise a second cable connector connected to an upper portion thereof. The second cable connector may include a pair of inverted and opposing J-shaped second cable connector members.
- The first cable connector may comprise a pair of spaced-apart opposing first cable connector members connected to the lower portion of the second post member. Further, the rail member may be detachably connected to the second post member and extend between the pair of first cable connector members. Each of the pair of first cable connector members may have a passageway formed therethrough. The guardrail system may also include a locking pin member that matingly engages the passageways to retain the rail member between the pair of first cable connector members.
- The rail member of the guardrail system may advantageously comprise a first rail member and a second rail member. The first rail member may be detachably connected to the second post member adjacent the first cable connector. The second rail member may be detachably connected to the second post member adjacent the second cable connector.
- The second post member may have a passageway formed therethrough. The guardrail system may also comprise a height fastener to matingly engage the passageway, and contact the first post member to fix a height of the second post member with respect to the first post member. This advantageously allows for the rails of the guardrail system to have an adjustable height. The rail member may be a steel cable. The first post member and the second post member may be polygonally shaped tubes.
- In one embodiment, the guardrail system may comprise a plurality of bases. Each base may be connected to a bottom portion of the respective first post member. Further, each base may have a plurality of passageways formed therethrough for receiving a respective plurality of fasteners to fasten the base to a surface.
- In another embodiment, the bases of the guardrail system may be sleeves for receiving a bottom portion of the first post member. Similarly, each base may have a plurality of passageways formed therethrough for receiving a respective plurality of fasteners to fasten the base to a surface.
- The guardrail system according to the present invention advantageously allows for simplified installation. More specifically, the rail member may be readily connected to the second cable connector by engaging the rail member between the pair of inverted and opposing J-shaped second cable connector members when the second post member is in a horizontal position. The second post member may then be rotated to a vertical position to retain the cable member between the pair of J-shaped members.
- A method aspect of the present invention is for installing a guardrail system. The method may include fastening a base of the first post member to a surface. The method may also include slidably engaging the second post member with the first post member, and detachably connecting a rail member to each of the plurality of posts so that the rail member extends between each of the plurality of posts.
- Another embodiment of the method for installing the guardrail system comprises fastening the plurality of bases to a surface, and slidably engaging the first post member of each of the posts with a respective base. The method may also include slidably engaging the second post member with the first post member, and detachably connecting a rail member to each of the plurality of post members so that the rail member extends between each of the plurality of posts.
