Description
- This is a continuation-in-part patent application taking priority from, Ser. No. 09/663,432 filed on Sep. 16, 2000.
- 1. Field of the Invention
- The present invention relates generally to stress skin panels and more specifically to an apparatus and methods for modifying a stress skin panel.
- 2. Discussion of the Prior Art
- A stress skin panel, also known as a structural insulated panel is a structural member used to fabricate buildings. The stress skin panels are joined together to form walls of a building instead of wood studs and wood panels. For example, to create openings for a window, the stress skin panel must be routed out to accept two vertical studs, and then may be routed out to accept a stud which is attached in between the two vertical studs above the window structure. The process of routing out the stress skin panel for the studs is very time consuming.
- Accordingly, there is a clearly felt need in the art for apparatus and methods for modifying stress skin panel to easily install a window, door, or any other appropriate item.
- The primary objective of the present invention is to provide an apparatus and methods for modifying a stress skin panel to easily accept a window, door, or any other item. A modified stress skin panel includes a stress skin panel and at least two substantially vertical studs which are horizontally spaced apart for the insertion of a window, door, or other structure. A stress skin panel includes an inner layer fabricated from a foam material such as polystyrene which is sandwiched between two outer layers of oriented strand board. The at least two substantially vertical studs are either molded into the inner layer during manufacture, or inserted after manufacture. A header stud may be fastened to the vertical studs in an area above a potential opening to support the load above the potential opening. The header stud could be attached to the two vertical studs before molding or after cutting out the potential opening. A support member could also be placed in or over the stress skin panel with an opening instead of using the header stud. Multiple substantially vertical studs may be molded or inserted into the stress skin panel to increase the load bearing ability or structural integrity thereof.
- Either wood or metal studs may be used. It is preferably to use standard wood studs, because carpenters are more accustomed to working with wood studs. The metal studs are preferably fabricated from a galvanized steel or a noncorrosive metal. Preferably, each substantially vertical stud extends from the bottom of the stress skin panel to the top thereof. The header stud may be attached to the at least two substantially vertical studs with any suitable assembly method. The header stud is not needed, if a support member is placed in or over the stress skin panel.
- A stress skin panel stud inserter includes a stud guide assembly, a heater element, a heater controller, a pair of rails, and a pair of clamps. The thickness of the stress skin panel fits between the pair of support rails. A clamp is slidably attached to each end of each rail. A slidable base rests on the top of each rail. The slidable base is secured to at least one rail. A stud guide is attached to the base with a gusset structure. The heater element is contained inside a heater cover which is fastened to the slidable base. The heater controller ensures that a metal stud is exposed to a substantially constant temperature of heat for later insertion into the stress skin panel.
- A metal stud is inserted into the stress skin panel by placing the stress skin panel stud inserter on top of the stress skin panel. The stress skin panel stud inserter is secured to the stress skin panel by closing the clamps on the stress skin panel. The metal stud is placed in the stud guide. The sliding base is moved such that the metal stud will be aligned with a position which will later define a vertical perimeter of the window opening. The heater controller is turned on so that the heater element may reach the desired temperature. The heater element heats the metal stud so that it may be pushed through the thickness of the stress skin panel. The heated metal stud will melt the inner layer of the stress skin panel to allow insertion of the stud.
- The metal stud will act as an integral member of the stress skin and will improve the amount of weight that may be placed on top of the stress skin panel. As many vertical studs as are required for rigidity and strength are inserted by the stress skin panel stud inserter. The gauge and cross section of the metal stud can also be varied to meet specific structural criteria.
- A second embodiment of a stress skin panel stud inserter utilizes a stud heater element which is attached to a bottom of a metal stud instead of the heater element in the heater cover. A heater controller is used to supply electrical current to the stud heater element through a pair of wires. The metal stud is forced into the stress skin panel utilizing a stud guide. The metal stud is forced through the stress skin panel until the heater element is fully exposed. The heater element is then removed from the bottom of the metal stud and the wires may be pulled out of the stress skin panel or left inside the metal stud.
- A third embodiment of a stress skin panel stud inserter includes a hot air shroud and an alignment jig. The hot air shroud is attached to a bottom of a wood stud. The hot air shroud includes a tube with an inside perimeter which is sized to be received by the bottom of the wood stud. An air inlet is formed on at least one side of the hot air shroud. A single air hose is attached to the air inlet. Hot air is forced through the air hose and hot air exits through an open bottom in the hot air shroud. The alignment jig is attached to a top of the stress skin panel. The alignment jig ensures that the wood stud with the hot air shroud attached thereto is inserted substantially perpendicular to a top of the stress skin panel.
- Accordingly, it is an object of the present invention to provide a stress skin panel stud inserter which allows a stud to be inserted into a stress skin panel to facilitate the easy installation of a window, door, or any other structure.
- Finally, it is another object of the present invention to provide a stress skin panel which may have its structural integrity increased by the inclusion of substantially vertical studs.
