Adjustable Post Cap

Description

BACKGROUND OF THE INVENTION

This invention provides an improved steel connector for joining a post to a beam, typically known as a column cap or a post cap. Typically, the joist and beam lie in a common plane with the end of the post abutting the bottom face of the beam or being in close proximity thereto. The use of the connector helps the connection to resist gravity, lateral and uplift loads.

DESCRIPTION OF THE PRIOR ART

Column caps and post caps are well known in the art. U.S. Pat. No. 963,585, granted to J. A. Kimball in 1910 teaches a sheet-metal, channel-shaped connector where legs for connecting to the post are bent down from the seat and then bent back on themselves 180 degrees to reach up and grab the sides of the beam. U.S. Pat. No. 1,848,085, granted to L. A. Eisenschmidt in 1932, also teaches a channel-shaped connector made from sheet-metal. In this patent the legs that grab the post are bent from the seat at its sides and the walls of the channel are bent up from the front and back edges of the seat. U.S. Pat. No. 2,084,758, granted to A. R. Anderson in 1937, also teaches a channel-shaped connector. In this case the legs for attaching the connector to the post are formed from portions that would otherwise be the walls of the channel and are bent down from the seat of the channel to grasp the post. This patent also teaches an extension on one of the sides of the channel that further strengthens the connection between the post and the beam. U.S. Design Patent D256,663, granted to Tyrell T. Gilb in 1980, also teaches a channel-shaped connector where legs for attaching to the post are formed from the walls of the channel and are bent down from the seat of the channel to grasp the post. U.S. Pat. No. 5,488,810, granted to Jim W. Horton in 1996, teaches a sheet-metal, channel-shaped connector where the legs for attaching the connector to the post are cut from the seat and extend downwardly from the walls of the channel. U.S. Pat. Nos. 10,273,678, 11,105,085, 11,598,082, invented by Sam Thomas Hensen, Emmet J. Mielbrecht, Timothy M. Stauffer and Jin-Jie Lin, teach a sheet-metal, channel-shaped connector where the legs for attaching the connector to the post are cut from the seat and wall of the channel and extend downwardly from the walls of the channel.

U.S. Pat. No. 5,697,725, granted to Evon M. C. Ballash and Michael Wagner, teaches a pair of identical, sheet-metal connectors for making a secure connection between a vertical stud disposed between horizontally-disposed top plate and bottom plate members. The identical connectors are substantially flat members with small tabs extending from the members, and the connectors have strengthening embossments that extend across the joint between the structural members that are connected. U.S. Pat. Nos. 7,065,932 and 7,356,973, granted to Charles Roesset and Louay A. Shamroukh, teach a pair of identical, sheet-metal connectors for making a secure connection between a vertical stud disposed between horizontally-disposed top plate and bottom plate members. The identical connectors are substantially L-shaped members, and the connectors have strengthening embossments that extend across the joint between the structural members that are connected.

The present invention improves upon the prior art devices by providing a connector that is easy to install as part of new construction or as a retrofit member to existing members. The present invention is also economical to produce while making a strong connection between the members.

SUMMARY OF THE INVENTION

The present invention provides a connection between a post or supporting member and a beam or supported member supported by the post that is easily erected. Typically, the supported member and supporting member are disposed orthogonally to each other, but they could be disposed at different angles to each other. In one embodiment of the invention, one sheet metal connector is attached to the vertical post and to the beam supported by the post. In a second embodiment of the invention, a pair of sheet metal connectors are attached to the vertical post in opposed relation and to the opposite faces of the beam supported by the post.

The connector of the connection is disposed in interfacing engagement with a first attachment face of the post. The connector has an elongated, substantially planar web having a longitudinal axis with a first end and a second end. The longitudinal axis is disposed substantially aligned with the long axis of the elongated post. The web has an exterior surface on one side of the web and an interior surface on the opposite side of the web. The interior surface of the web interfaces with a portion of the front face of the post. The web is formed with one or more strengthening embossments that are preferably elongated, linear members that run along or parallel to the longitudinal axis of the connector across the joint between the supported and supporting structural members. The connector is also formed with first and second side members that attach to opposed side edges of the lower portion of the web.

The connector is also formed with a substantially planar first lateral plate laterally connected to a first lateral side of the upper portion of the web. The connector is also formed with a substantially planar second lateral plate laterally connected to a second lateral side of the upper portion of the web.

To make the connection to the post, fasteners are driven through the lower portion of the web into the first attachment face of the post, and fasteners are driven through the first and second side members of the connector into the first and second side faces of the post.

To make the connection to the beam, separate fasteners are driven through the upper portion of the web and through the first and second lateral plates into a face of the beam. The preferred fasteners are self-drilling, self-tapping screws or nails, depending on the load values desired for the connection.
