Abstract
A wood based panel having at least one spacer, spaced at intervals or continuously, on a square edge in which the spacer will deform or be forced into an adjacent panel when subjected to linear expansion forces.
Description
- This application claims the benefit of U.S. Provisional Application No. 60/354,471, entitled SELF GAPPING WOOD BASED PANELS, filed Feb. 5, 2002.
- The present invention relates to wood based panels used in building, cladding, and flooring.
- All wood-based panel products will undergo dimensional changes when exposed to elevated moisture conditions. Most panels are put into service conditions at less than equilibrium moisture content. Consequently, there would be an uptake in moisture from the surrounding environment and “growth” in panel dimensions. The term used to describe this phenomenon is linear expansion, whereby physical dimensions (length and width) will grow with moisture uptake.
- There are a number of consequences to linear expansion when
panels 1 are fitted tightly together atjoints 3 prior to expansion (see prior art FIGS. 1-5): - 1)
Panels 1 will buckle as at 4 somewhere along the unsupported span (FIG. 1); - 2) Excessive deflection as at5 may result (FIG. 2), putting
floors 10 out of level; and - 3) The upper8 and lower 9 surfaces (top and bottom faces) of the
panel 1 will flare out as at 7 at the panel-to-panel joint 3 in a release of forces (FIG. 3). This flaring 7 of panel edges atjoints 3 is sometimes attributed wholly to edgeswell, where the uptake of moisture causes “expansion” in the vertical direction, but is more likely to be a combination of both. Flare-out 7 occurring prior to finishing the structure would necessitate sanding, adding additional cost to construction. Occurrence of edge flaring 7 after finishing would cause gypsum board (drywall) 21 to crack,exterior siding 25 to bulge out,floors 10 to bulge out, etc. - 4) Expansion of the floor panels may push
walls 13 out of plumb (FIG. 4); - 5) Expansion of the
wall system 20 might pushfloors 23,ceilings 24 androofs 26 off level (FIG. 5). - Given the above “expansion” characteristics and consequent impacts are well known, most manufacturers, their third-party certification agencies, and governing standards prescribe a minimum gap at panel joints to allow for linear expansion. The degree of gap stipulated is dependent on the inherent linear expansion character of the substrate (i.e., some panels will expand more than others).
- Most claims and problems of the above nature presented to panel manufacturers arise from improper installation—the panels were not gapped as prescribed. Whether due to inexperienced installers, insufficient gapping from imprecise measurement tools, or time constraints in building schedules, proper gapping is not being done on all product installations.
- In 1976, Pettersson et al. filed U.S. Pat. No. 4,095,913 disclosing a tongue and groove joint where the base of the groove is provided with one or more protuberances to space the tongue from the base of the groove. The protuberances are made to be deformable to permit the panels to swell without deforming the structure made from the panels. However, it is believed that this has never been commercialized.
- Thus, problems associated with wood based panels being installed without proper spacing has persisted for many years without solution.
- The wood based panel of the present invention includes a narrow spacer projecting, at least at spaced intervals, from at least one flat edge of the panel a specified distance. The spacer width is less than the thickness of the edge of the wood based panel, yet the width is sufficient to give the spacer enough strength to resist damage during handling and installation of the wood based panel. Upon linear expansion the spacer will collapse or be pushed into an adjacent wood based panel thereby allowing multiple wood based panels to be placed adjacent to one another and withstand the forces of linear expansion.
- These and other features, advantages and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following specification, claims and appended drawings.

In contrast,panel end edge 46 is square or flush, and a relatively narrow, relativelythin spacer 34 a projects from opposite end edge 47 (FIGS. 9 and 11). - A process of manufacture is depicted by referring to FIGS. 12 and 13. Wood based
panel 30 is fed between two sawblades 50 at itsedges 33, thereby cuttingpanel 30 from both top andbottom surfaces spacer 34 projecting fromedge 33, betweensaw blades 50. - An alternate process of manufacture is depicted in FIGS. 14 and 15.
