Abstract

The invention relates to structural panel systems with at least a four-layered generally in-plane sidelap, at least a three layer generally in-plane sidelap, or corner sidelaps of various layers, and methods for manufacturing and assembling structural panel systems with these types of sidelaps. The structural panels may be provided with an edge having a “lower lip” with two layers, and an opposite edge having an “upper lip” with two layers. Individual panels may be coupled together by placing the upper lip of a first panel over the lower lip of an adjacent panel, thus creating an un-joined sidelap. The lips may have nested portions for helping to place one lip over the other. The panels may be operatively coupled through various couplings configurations, such as fasteners, welding, cutting the sidelap, or the like. The present invention improves the shear strength of the structural panel system and reduces costs.

First claim

What is claimed is:

1. A method of assembling a structural panel system, the method comprising:
assembling a first structural panel to at least one of two or more support members, wherein the first structural panel comprises first top flanges, first bottom flanges, first webs, and at least one edge of the first structural panel comprising an upper lip, wherein the first top flanges are operatively coupled to the first bottom flanges through the first webs;
assembling a second structural panel to at least one of the two or more support members, wherein the second structural panel comprises second top flanges, second bottom flanges, second webs, and at least one edge of the second structural panel comprising a lower lip, wherein the second top flanges, are operatively coupled to the second bottom flanges through the second webs;
assembling the upper lip of the first structural panel over the lower lip of the second structural panel to create a sidelap with three or more layers, wherein the sidelap is in a generally in-plane orientation with respect to the first structural panel and the second structural panel, and wherein the upper lip comprises a first upper layer and a second upper layer folded back on the first upper layer and/or the lower lip comprises a first lower layer and a second lower layer folded back on the first lower layer to form the sidelap with three or more layers; and
forming one or more couplings in the three or more layers of the sidelap to couple the first structural panel to the second structural panel.

2. The method of claim 1 , wherein the lower lip comprises the first lower layer and the second lower layer; and wherein the second lower layer is folded back on top of the first lower layer or back below the first lower layer to form the lower lip with two layers in the generally in-plane orientation with respect to the second structural panel.

3. The method of claim 2 , wherein the second lower layer is folded on top of the first lower layer or folded under the first lower layer.

4. The method of claim 1 , wherein the sidelap is a nested sidelap, and wherein the lower lip of the nested sidelap comprises:
a nested portion formed at a distal portion of the lower lip of the second structural panel that extends from the generally in-plane orientation of a proximate portion of the lower lip;
wherein the nested portion extends around a web of the first webs adjacent the upper lip such that a flange corner of the first structural panel and the nested portion of the lower lip rest within each other; and
wherein the nested portion of the lower lip of the second structural panel inhibits movement between the first structural panel and the second structural panel of the nested sidelap before the one or more couplings are formed in the nested sidelap.

5. The method of claim 1 , wherein the upper lip comprises the first upper layer and the second upper layer; and wherein the second upper layer is folded back on top of the first upper layer or back below the first upper layer to form the upper lip with two layers in the generally in-plane orientation with respect to the first structural panel.

6. The method of claim 5 , wherein the second upper layer is folded on top of the first upper layer or folded under the first upper layer.

7. The method of claim 1 , wherein the sidelap is a nested sidelap, and wherein the upper lip of the nested sidelap comprises:
a nested portion formed at a distal portion of the upper lip of the first structural panel that extends from the generally in-plane orientation of a proximate portion of the upper lip;
wherein the nested portion extends around a web of the second webs adjacent the lower lip such that a flange corner of the second structural panel and the nested portion of the upper lip rest within each other; and
wherein the nested portion of the upper lip of the second structural panel inhibits movement between the first structural panel and the second structural panel of the nested sidelap before the one or more couplings are formed in the nested sidelap.

8. The method of claim 1 , wherein the sidelap formed from assembling the upper lip over the lower lip comprises four or more layers; and wherein the one or more couplings are formed in the four or more layers of the sidelap.

9. The method of claim 1 , wherein the one or more couplings are fasteners that operatively couple the upper lip to the lower lip.

10. The method of claim 1 , wherein the one or more couplings are formed by welding the upper lip to the lower lip, or by cutting the upper lip and the lower lip to operatively couple the upper lip to the lower lip.

11. The method of claim 1 , wherein the upper lip is formed at least partially along a web of the first webs and is bent at a flange corner in the generally in-plane orientation with respect to the first structural panel to form a generally in-plane edge of the first structural panel, and wherein the lower lip is formed at least partially along an edge of the second structural panel having a proximate portion in the generally in-plane orientation with respect to the second structural panel and a distal portion that extends from the proximate portion in an out-of-plane orientation with respect to the second structural panel such that the lower lip and the upper lip formed along the web, the flange corner, and the generally in-plane edge rest within each other.

12. The method of claim 11 , wherein the sidelap comprises four or more layers.

13. The method of claim 1 , wherein the lower lip is formed at least partially along a web of the second webs and is bent at a flange corner in the generally in-plane orientation with respect to the second structural panel to form a generally in-plane edge of the second structural panel, and wherein the upper lip is formed at least partially along an edge of the first structural panel having a proximate portion in the generally in-plane orientation with respect to the first structural panel and a distal portion that extends from the proximate portion in an out-of-plane orientation with respect to the first structural panel such that the upper lip and the lower lip formed along the web, the flange corner, and the generally in-plane edge rest within each other.

14. The method of claim 13 , wherein the sidelap comprises four or more layers.

15. The method of claim 1 , wherein the one or more couplings in the sidelap with three or more layers improves a shear strength of the sidelap with three or more layer by greater than a factor of 1.05 over a sidelap with two layers; wherein the one or more couplings in the sidelap with three or more layers results in the shear strength that is the same as or similar to the sidelap with two layers with at least 5 percent fewer couplings in the sidelap with three or more layers; or wherein the one or more couplings in the sidelap with three or more layers results in the shear strength that is the same as or similar to the sidelap with two layers having a material thickness of the first or second structural panels that is at least 5 percent thinner than a thickness of a structural panel of the sidelap with two layers.

16. The method of claim 1 , wherein the upper lip comprises the first upper layer and the second upper layer, and the lower lip comprises the first lower layer and the second lower layer, and wherein the sidelap formed from the upper lip and the lower lip comprises four or more layers.

17. A method of assembling a structural decking panel system, the method comprising:
assembling a first structural panel to at least one of two or more support membe
