IIRC when all edges were nailed it did not make any difference to the strength, or maybe just a minor difference, if panels were vertical or horizontal. Here in Southeast NC, we use H-clips not only for structual reasons, but also for the 1/8 inch gap between the sheets. The living hinges 18 act to spring-load the lead- ins 16 by providing a hinged surface that flexes away from the material 11 as the H clip 10 is being inserted and then springs towards the material 11 as the H clip 10 is fully inserted onto the material 11.

It is understood that the invention is not confined to the particular construction and arrangement of parts herein illustrated and described, but embraces such modified forms thereof as come within the scope of the following claims. Hi-Grip stainless steel hose clips have fast become the industry standard for marine applications throughout the world due to their high quality and performance. Although I wouldn’t say support would be the right word…if you step on the joint it will still bow down. The ski-shape of the lead- ins 16 combines with the living hinges 18 and contoured face 20 to provide a spring-loaded, angled surface providing the necessary flexibility for the H clip 10 to be quickly and easily inserted onto the edge of a piece of building material 11. H-clips provide additional stiffness between bearing points for the unsupported edges of wood panel (plywood or OSB) roof sheathing, along with the necessary 1/8” gap for expansion, as shown below illustrated on a bag of Simpson H-clips.the arms 12 are slightly tapered such that the distance between the arms 12 at ends 13 is closer than the distance between the arms 12 at the spacing bar 14 . In addition, once the lead-in 16 is inserted onto the edge of the material 11, the living hinges 18 help to properly grip the material 11, thereby securing the H clip 10 onto the material 11. the contoured face and living hinge provide the necessary flexibility to allow each ski-shaped lead-in to be quickly and easily inserted onto a piece of building material.

Now you have ten nails in the sheet and it's flush with the rest of them and you go to the next sheet and repeat. With a 2 x 4 placed, with the 1 1/2" side facing down, between the studs, providing a 3 1/2" nailing surface? the contoured face 20 provides a smooth, contoured surface for the material 11 to slide over as the H clip 10 is completely inserted. Plywood clips connect the panel edges of plywood, thus reinforcing the stability of the 2 pieces of plywood by ensuring they don't shift and become uneven over time.

Depending on the job I will pull my o/c measurements as I go or premark the sheet and then tack the top of the sheet at each rafter and drive it home. All Hi-Grip stainless hose clips have fully rounded edges to give the best possible protection to the hose. each arm 12 includes a ski-shaped splayed prong or lead-in 16 connected to the end 13 by a living hinge 18 . New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging .

the contoured face 20 of the lead-in 16 rotates on the hinge 18 , as illustrated by reference number 17 in FIG. In fact the lumber yard brought up a pile of cull 2x4s and 6s to use for blocking - bracing and farm - ranch use and cost us nothing if I remember correctly.

If you are tying into an existing roof I like to stich in the new panels by removing the 4 foot end panels in the old roof and then bridging the seam with a new 8 foot panel. Conventional clips are small, usually metal or galvanized clips formed in the shape of an “H” that fit between the joints of two pieces of building material, such as plywood or wafer board sheets, to stiffen the joint. Have someone come in a clip the ends of nails so we can install 2x4s flush with the plywood in the remaining 75% of the area. the H clip 10 is generally a one-piece unit which includes a pair of identical and opposed arms 12 in a modified parallel position to each other and connected by a spacing bar 14 .

If any ads are present below my answer or words underlined/colored, I do not condone/support/use the product or services listed/linked to, they are there without my consent. Now that we have that sorted out, it would seem like a pretty bad idea to substitute nails and blocking with a few clips.They improve the longevity and durability of the plywood by ensuring that the plywood doesn't shift and become uneven over time. The lumberyard told us to install H-clips as for conventional sheathing, but after taping over all the seams between panels, we found that water leaked through the tape at almost every clip. The H clip includes two opposed arms connected by a spacer bar, where each arm ends in a ski-shaped lead-in having a contoured face and a living hinge. In this manner, the entire arm 12 of the H clip 10 is flattened along the surfaces 15 of the building materials 11 . the living hinges 18 also provide the lead-ins 16 the necessary flexibility to be quickly and easily inserted onto the edge of a piece of building material 11 .
