Slip bracket connector for rigid members
A one-piece rigid connector allows a nominal construction wood member to slip axially while fixed at its distal end, to accommodate the naturally occurring shrinkage of lumber. The connector surrounds the wood member and attaches to a second wood member to secure the members together. The connector may be slightly larger radially than the first member to accommodate natural movement. In one embodiment, the connector is made of a light gauge sheet metal and attaches a vertical baluster to the horizontal lower deck rail of an elevated wood deck guard rail system. The connector secures the baluster horizontally, but allows the baluster to move vertically to accommodate expansion or contraction of the baluster after construction. The distal end of the baluster is secured using conventional wood screw attachment. The connector includes tabs on each side to allow fastening of the connector to the lower deck rail using conventional wood screws.
1. A method of attaching a first wood member to a second member so that the natural dimensional fluctuations of the first wood member are not restricted, the method comprising the following steps:
placing a bracket around the first wood member such that the bracket is in contacting relationship with the second member and in non-contacting relationship with the first wood member, the bracket being a three-sided structure including:
a planar front portion and planar left and right portions attached to opposing edges of the front portion and defining a proximal end and a distal end of the bracket that are each open, the left, front, and right portions leaving a clearance gap between the bracket and the first wood member; and
at least two tabs, one of the tabs attached to the left portion of the bracket and another of the tabs attached to the right portion of the bracket, each of the tabs including a first section projecting from the respective left or right portion of the bracket and a second section projecting from and angularly transverse to the first section, wherein only the first section or the second section of each tab has at least one aperture disposed through the tab for receiving a fastener;
abutting at least one of the tabs attached to the left portion and at least one of the tabs attached to the right portion against the second member such that the first section of each tab makes flush contact with the second member; and
driving a fastener through each aperture into the second member, the fasteners securing the bracket to the second member such that the bracket remains in non-contacting relationship with the first wood member, the non-contacting relationship creating a clearance gap, thereby permitting natural dimensional fluctuations of the first wood member.
2. The method of claim 1 wherein the bracket extends around three sides of the first wood member.
3. The method of claim 1 wherein the bracket is substantially u-shaped.
4. The method of claim 1 wherein the bracket is stamped out of a single piece of sheet metal and bent into form.
5. The method of claim 1 wherein the first section of the tab attached to the left portion of the bracket is coplanar with the first section of the tab attached to the right portion of the bracket.
6. The method of claim 1 wherein the first wood member is a baluster.
7. The method of claim 6 wherein the baluster is rigidly attached at an end opposite the bracket to a third wood member.
8. The method of claim 1 wherein the natural dimensional fluctuations include allowing for longitudinal and radial expansion of the first wood member within the bracket.
