1. Technical Field of the Invention
The present invention relates generally to a hanger for supporting a connection between two structural members and, in particular, a hanger for supporting a post-to-beam connection.
2. Description of Related Art
Many construction projects require the attachment of a horizontally extending structural member to a side surface of a vertically extending structural member. One specific example of such a project concerns the attachment of a beam member 10 to the side surface 12 of a post member 14 as shown in
To provide for improved structural support there would be an advantage to instead use a hanger (clip or bracket) which is secured to the side surface of a post member and further supports an underside surface of the beam member. A number of exemplary hangers of this type are known in the art. However, these hangers suffer from a number of drawbacks.
First, the hangers are typically made of stamped and folded galvanized steel and thus possess a utilitarian appearance driven by functional configuration. In most applications, it is preferred that such galvanized hangers and other such hardware not be visible. It is thus typical for some form of finish carpentry to be used to conceal the hanger from view. For example, the finish carpentry may box or case around the hanger with wood trim pieces of a type similar to, or complementary of, the post and beam members. There is accordingly an added cost to use of such galvanized hangers that is associated with the need to hide the hanger itself.
Second, the hangers are typically manufactured with sizes specifically selected for commonly used dimensional structural members (i.e., dimensional lumber). It is known in the art that the stated dimensional size of a wood structural member is not the actual dimensional size. For example, a 2×6 wood beam will not typically measure two actual inches in thickness and six actual inches in width. This is especially the case when the wood structural member is something other than “rough cut” (where rough cut members more conventionally are dimensionally accurate or close to dimensionally accurate). The differences in size may, for example, be geographic such that a 2×6 wood beam in one geographic region is one size and a 2×6 wood beam in another geographic region is another size. Alternatively, the differences in size may vary from lumber mill to lumber mill, or vary depending on the treatment made to the wood. It is not uncommon for a “2×6” wood beam to have thicknesses varying from 1.5 to 2.0 inches and widths varying from 5.5 inches to 6.0 inches. The conventional galvanized hangers, constructed solely for commonly encountered dimensions, are not well suited to handle the dimensional variability of structural members, and in particular are not configured to adjust to differences in thickness.
What is needed is a post-to-beam hanger which supports the underside surface of the beam along with secure attachment to the post, is adjustable to handle dimensional variability of structural members and is configured to present an attractive appearance obviating the need for finish concealment.
In an embodiment, a multi-piece hanger comprises: a first L-shaped bracket having a first mounting flange and a first interlocking flange, the first interlocking flange including an extending tab member; and a second L-shaped bracket having a second mounting flange and a second interlocking flange, and further including, at a bend, at least one slot sized and shaped to receive the extending tab member when the first interlocking flange and second interlocking flange are positioned adjacent each other.
In an embodiment, a multi-piece hanger comprises: an L-shaped bracket having a first mounting flange and an interlocking flange, the interlocking flange including an extending tab member; and a plate member having a second mounting flange and further at least one slot sized and shaped to receive the extending tab member.
In an embodiment, an apparatus comprises: a post member having a side surface; a beam member having a side surface and an underside edge surface; a first L-shaped bracket having a first mounting flange attached to the side surface of the post member, and further including a first interlocking flange supporting the underside edge surface of the beam member, the first interlocking flange including an extending tab member; and a second L-shaped bracket having a second mounting flange attached to the side surface of the beam member, and further including a second interlocking flange positioned adjacent the first interlocking flange, and further including, at a bend, at least one slot sized and shaped to receive the extending tab member.

The post bracket 116 and beam bracket 118 may be made from steel sheet cut in a desired pattern and shaped, for example by bending, into a desired shape. The steel may be coated by painting or powder coating. The surface may be smooth or distressed. Alternatively, the post bracket 116 and beam bracket 118 may cast or otherwise molded.
Reference is now made to
A central portion of the mounting flange 124 includes a plurality of mounting openings 128. The mounting openings 128 are configured to receive a mounting device 120 (such as a screw or bolt) for attaching the post bracket 116 to the side surface 112 of the post member 114 (
The reason for providing two pairs of openings is to allow adjustment in relative positioning and separation of the mounting devices 120. It will be noted that only one pair of openings will typically be used on the post bracket 116. To hide the unused pair of openings, the mounting devices 120 may be sized to cover both pairs of openings when installed, or may use other techniques, such as a washer or other structure, sized sufficient to cover both pairs of openings. It will be understood that only one pair of openings could be provided as shown in
An end edge 134 of the interlocking flange 126 includes a plurality of cut-outs 136 which define at least one tab (or projection) 138.
An upper portion of the mounting flange 24, and specifically a peripheral edge, may include ornamental features 170.

A central portion of the mounting flange 144 includes a plurality of mounting openings 148. The mounting openings 148 are configured to receive a mounting device 120 (such as a screw or bolt) for attaching the beam bracket 118 to a side surface 122 of the beam member 110 and further to attach the beam member 110 to the side surface 112 of the post member 114 (

In assembling the multi-piece post-to-beam hanger 100, the user selects the desired post bracket 116 and beam bracket 118 (based for example on ornamental features). The post bracket 116 is positioned on the side surface 112 of the post member 114 such that the support surface 160 provided by the interlocking flange 126 is set at a desired height for the beam member 110. Mounting devices 120 are then used to attach the post bracket 116 to the post member 114. The beam member 110 may then be placed to rest on the support surface 160 provided by the interlocking flange 126. This is advantageous because it obviates the need to manually hold the beam member in place at the desired height during beam installation. The beam bracket 118 is then positioned on the side surface 122 of the beam member 110 with the interlocking flange 146 underneath the interlocking flange 126 and the tabs 138 formed by the cut-outs 136 in the edge 134 of the interlocking flange 126 inserted into the slots 156 formed at the bend where the mounting flange 144 meets the interlocking flange 146. Mounting devices 120 are then used to attach the beam bracket 118 to both the beam member 110 and the post member 114.
As an alternative construction, a separate mounting device (such as a screw or bolt) may be used to attach the beam member 110 to the post member 114 prior to installation of the beam bracket 118. With this construction, the separate mounting device must be countersunk or recessed into the surface 122 of the beam member 110. The beam bracket 118 is then positioned on the side surface 122 of the beam member 110 with the interlocking flange 146 underneath the interlocking flange 126 and the tabs 138 formed by the cut-outs 136 in the edge 134 of the interlocking flange 126 inserted into the slots 156 formed at the bend where the mounting flange 144 meets the interlocking flange 146. Mounting devices 120 are then used to attach the beam bracket 118 to the beam member 110.
To address the issue of dimensional variability with respect to the beam member 110, the tabs 138 formed by the cut-outs 136 in the edge 134 of the interlocking flange 126 are sized to support a range from the largest to the smallest expected dimensional thickness for the beam member 110 (i.e., the thickness of edge surface 162). Thus, when a thicker beam member 110 is used, the tabs 138 will still engage the slots 156. However, when a thinner beam member 110 is used, the tabs 138 will pass further through the slots 156 to accommodate the thinner beam member while maintaining a flush attachment of the mounting flange 144 to the side surface 122 of the beam member 110. In an implementation, the tabs 138 formed by the cut-outs 136 may present a tab length of about 0.5 inches. This tab length permits a range of adjustment interlocked positioning of the beam bracket 118 relative to the post bracket 116 so that the beam bracket 118 can be positioned flush against the side surface of the beam member, no matter its actual dimensional size.
