This disclosure relates generally to the field of tooling to facilitate the installation of standing seam roofs on pre-engineered building systems. More specifically, the disclosure relates to the field of specialized tooling to quickly and easily create notches in metal roof panels to allow panels to properly nest within a lap condition.
Metal roofs on pre-engineered building systems include a deck formed of a plurality of panels connected together and to the building structural elements in a non-penetrating manner Clip units and edge crimping attach these roof panels together and to the building. When metal panel roofs are installed on buildings there are overlap conditions to create a watertight seal. For example, when the roof is sufficiently wide and there are multiple panels required to cover the distance from the roof ridge to the eave, the panels will be overlapped. Specifically, the upslope panel, closest to the roof ridge, is laid atop and overlaps the downslope panel by several inches. The upslope and downslope panels at their longitudinal edges are then secured to one another with attachment clips. Illustrative of the overlapping roof panel concept is that found in a standing seam roof system. A standing seam roof is a metal roof that fastens to a structure without holes or penetrations.
A standing seam roof acts like a single steel membrane to protect the building. The roof is fastened to the structure using a mechanical seaming tool known as a “seamer.” The seamer tool bends the lateral metal ribs of the roof panel, forms the final shape and connects the roof panels to the structure without penetrating the roof. A structural standing seam roof panel system meets performance goals by being constructed with a raised portion where the lateral edges of the two panels meet, enhancing overall weather resistance. The lateral edges of the panels interlock in such a way that allows thermal expansion without damage to the roof structural components. The standing seam roof system relies upon the locking seam to assure complete weather-tightness and structural integrity. The standing seam of the roof system is machine formed on site with the seam as the roof system is installed, assuring a tight permanent seam.
At certain locations on the roof during installation there will be multiple overlaps of roofing panels. As discussed above, at the upslope and downslope panel overlap there will be two layers of panel that when wrapped in the double lock seam will form four wrapped layers. If the overlap from the laterally adjacent panel is included in the wrap this may create an undesirable configuration which can lead to a capillary action resulting in roof leaks. At present, when there is an overlap of excessive material, field notching has been completed with hand snips which is labor intensive, inaccurate and often impractical in certain roof configurations. Consequently, there is a need for a tool to quickly, and easily, remove excess material when there is an overlap condition that exceeds the limit of four layers in the seamed overlap.
The disclosed notching tool is capable of quickly and accurately removing excess material from a roof end lap condition. By simply sliding the area of the roof panel to be notched between the male and female dies of the tool and applying pressure to the handle components undesirable sheet metal can quickly be removed from the roof panel.
The present disclosure details a tool for notching panels of a roof system to allow the roof panels to properly nest within a lap condition. Sometimes a portion of the lapped area of the panel must be notched so materials do not build up too many thicknesses thereby preventing the proper formation of a water tight seam.
The notching tool is comprised of two mechanism assemblies, each assembly is comprised of two handles with the proximal end of each handle connected to a jaw body and the distal end of each handle connected to a handle separation member that spans the distance to the opposing mechanism assembly. The jaw bodies are articulated through the use of major and minor rotation links at the proximal end of each handle and the jaw bodies rotate about a fulcrum formed into an inner side surface of one of the jaw bodies. The fulcrum extends into a slot or cutout in the opposing jaw body and the fulcrum is capable or rotating within the cutout. The separation distance between the jaw bodies is maintained by the use of link plates that span between and are secured to the first and second jaw bodies of each mechanism assembly. At the distal end of each of the jaw bodies, a male and female die span the distance between the first and second mechanism assemblies.
The male die spanning the distal end of the jaw bodies includes an overhang element. When pressure is applied to the handle separation members by the user of the tool, the force is transmitted along the handles to the proximal end of the jaw body. The proximal end of the first and second jaw bodies of both mechanism assemblies rotate away from one another due to the functionality of the major and minor rotation links. The proximal ends of the jaw bodies rotate about the fulcrum causing the distal ends of both jaw bodies of the first and second mechanism assemblies and the associated male and female dies to converge upon one another.
When the overlapping edge of a roof panel is positioned between the male and female dies and pressure is applied to the handle separation members the overhang element of the male die advances against the panel material. As the overhang element bites into the panel material, the overhang element severs the material from the panel thereby accomplishing the desired material removal.
The foregoing and other features and advantages will be apparent from the more particular description of preferred embodiments, as illustrated in the accompanying drawings, in which like reference characters refer to the same parts throughout the different views. The drawings are not necessarily to scale; the sizes of elements may be exaggerated for clarity.
A pre-engineered building is a type of building that consists of several factory-built components or units that are assembled on-site to complete the unit. Pre-engineered buildings typically utilize roof framing members that span parallel to the building eave, and support the roof decking or sheeting. In order for metal roof panels to properly nest within an end lap condition a portion of the lapped area of the panel must be notched so that the roof seams do not include an excessive number of layers of wrapped material. Sometimes roof panel notching is accomplished in the factory where the roof panels are fabricated. But in most situations, notching the roof panels occurs on-site and the only way to notch a roof panel, prior to the disclosed notching tool, is to use hand snips, which are labor intensive, inaccurate and impractical in many situations.

In operation, as best seen in
The edge portion to be notched is positioned between the female and male dies 128, 142 and the operator of the notching tool applies pressure to the handle separation members 108, 110 in order to move them together as depicted by the arrows in
As the major and minor rotation links 168, 164 are rotated about the proximal ends 166, 167 of the first and second jaw bodies 134, 148 of both the first and second mechanism assemblies 104, 106 the hinge 170 connecting the rotation links begins to rotate about the pin 172 passing through the knuckles 174 of the hinge 170. As the hinge 170 rotates toward the distal end of the jaw bodies 134, 148 this causes the proximal ends 166, 167 of the first and second jaw bodies of both the first and second mechanism assemblies 104, 106 to move away from one another. The movement away from one another by the proximal ends of the first and second jaw bodies occurs due to the placement of the fulcrum 182 against the inner side surface 190 of the opposing jaw body. With the continued movement of the handle separation members 108, 110 toward one another the proximal ends 166, 167 of the jaw bodies 134, 148 diverge from one another and the distal ends 132, 146 of the jaw bodies 134, 148 converge upon one another with rotation of the jaw bodies, relative to one another, taking place at the fulcrum 182.
The link plate 178 connecting the first and second jaw bodies on both the first and second mechanism assemblies 104, 106 maintains a consistent separation of the jaw bodies at the fulcrum 182. As the operator continues to press the handle separation members 108, 110 toward one another and the jaw bodies 134, 148 rotate about the fulcrum 182 the distal ends 132, 146 of the jaw bodies move toward one another. As the handles are moved closer together the overhang element 156 of the male die 142 will contact the roof panel 12. As additional pressure is applied to the handle separation members 108, 110, force is transferred to the jaw bodies and ultimately to the overhang element 156. With the application of sufficient force, the overhang element 156 severs the roof panel material at the desired location.
In an alternative embodiment, a first connecting rod extends between the minor rotation links of the first and second mechanism assemblies and a second connecting rod extends between the major rotation links of the first and second mechanism assemblies. Secured to and extending away from the midpoint of each of the first and second connecting rods are a single handle. This alternative embodiment is comprised of only two handles instead of four and also does not utilize two handle separation members. Consequently, the alternative embodiment with only two handles instead of four, is lighter and easier to transport. Operation of the two handled embodiment is similar to the four handled embodiment in terms of the convergence of the distal ends of the two handles that serves to create a convergence of the male and female dies in order to notch the metal roof panel. It is also contemplated that the male and female dies may be secured in the opposite orientation from one another as detailed above without substantially altering the operation of the roof panel notching tool.
Many different arrangements of the various components depicted, as well as components not shown, are possible without departing from the spirit and scope of the present invention. Embodiments of the present invention have been described with the intent to be illustrative rather than restrictive. Alternative embodiments will become apparent to those skilled in the art that do not depart from its scope. A skilled artisan may develop alternative means of implementing the aforementioned improvements without departing from the scope of the present invention.
