Description

AUSTRALIA
Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT SLOT TONGUE METHOD OF PREFABRICATING STEEL WALLS AND OPEN WEB TRUSSES FOR DOMESTIC AND COMMERCIAL CONSTRUCTION The following statement is a full description of this invention, including The best method of performing it known to me The invention is described in the following statement SLOT TONGUE METHOD FOR THE PREFABRICATION OF STEEL WALLS AND OPEN WEB TRUSSES Page 1.
For many years, cold rolled sheet.metal has been used in the construction of walls and open web trusses in the domestic and commercial Ibuilding industry.
Whereas the walls and trusses when prefabricated and delivered on site, are quite easily erected into a building or structure the actual prefabrication of these components pose many problems, which would make it difficult, if not impossible to prefabricate the walls and trusses on site.
The walls and trusses are normally fabricated using a jig to hold the components in their relative positions until secured to each other by welding, pop-riveting, or mechanically fastening. This requires extensive time and therefore makes the structures rather expensive.
The slot and tongue method is designed to eliminate the need for a jig and any form of fastening, and would enable the components to be assembled by a person or persons of no technical ability, on site if required The slot and tongue method consists of a series of slots and tongues, punched into individual components cut precisely to fit the position in the finished wall frame or truss. The slots are designed to locate the individual components and the tongues are designed to secure them when located A wall consists of a top and bottom plate, cut to a predetermined length, studs fitted into the top and bottom plate, spaced to suit the building specifications. Noggins placed between the Individual studs, and at least one brace to hold the wall square and rigid.
*In the slot and tongue method the components should be manufactured as follows.
The metal to be used to form the top and bottom plates, should be cut longer than the required length to allow for the cut out(as shown in Fig.l-l) from each corner leaving a piece of metal which will be bent up later. The metal is now roll formed in the normal fashion.
A series of slots are punched in the channel at predetermined stud centers the width of the slots should be adequate to accommodate 3 thicknesses of the metal to be used to form the studs, the first and last slot are punched in line with the beginning of the flanges of the channel, and must not extend outside this line. (As shown in Fig 1-2) .i The metal to be used to form the studs should be cut longer than the required length to allow for the cut out as shown in Fig.2-3) to leave a tongue, at each end, this tongue should be slightly smaller at it's base than the slots punched in the top and bottom plate and be tapered to simplify the introduction of the tongue into the slot provided in the top and bottom plates. An aperture should be punched at each end of the stud preferably square. The distance between this aperture and the base of the tongue should be equal to the height of the flange in the top and bottom plate. This aperture is to provide access for pipes or electrical wiring. (As shown in Fig2-4) A slot as described for the top and bottom plates is punched at the noggin line. The stud should now be roll formed in the normal fashion.
Page 2.
The metal to be used to form the noggin should be cut longer than the required length to allow a tongue to be provided at each end similar to the stud (As shown in Fig 2-3) and can now be roll formed.
It is recommended that a K brace be used as follows, (As shown in Fig 5-8&9) Because the brace is installed diagonally between the top or bottom plate and the noggin, the portion of metal that will form the flange should be cut back as shown in (Fig 4-6) to suit the position it is meant to occupy. It can now be roll formed as normal.
When a wall to be fabricated contains a window or a door the stud on each side of this aperture Should have an additional slot or slots to accommodate the head of the door or the head and sill of the window (As shown in Fig 5-10) The normal metal open web truss consists of the following, the top core the bottom core and diagonal webs, it will be understood that the top and bottom core will be manufactured in a similar manner as the top and bottom plate of the wall frames and the diagonal webs will be similar to the braces already described.
The channel to be used to form the top core should be cut to the required length, the first and last slot should be punched to comply with the position where the top and bottom core join. Other slots are punched to accommodate diagonal webs as specified by the truss designer.
The metal to be used to form the bottom core should be cut longer than the required length to allow for the formation of a tongue at each end. Because it joins the top core at an angle less than degrees (As shown in Fig 6-11) the metal which will form the flanges of the bottom core should be cut back to allow the bottom core to be fitted exactly. The metal may now be roll formed as normal. Slots can now be punched to accommodate the diagonal webs. (As shown in Fig 6-12) If a slot is punched at each end of the bottom core, at a distance equal to the width of the wall on which it will sit, from the base of the tongue a bracket which will be described later can assist in holding the truss to the wall on which it sits The metal to be used to form the webs, should be cut longer to allow for the formation of a tongue at each end. Because the webs are installed diagonally the portion of metal which will be required to form the flange as described in the brace in the wall frame (As shown in Fig 4-6) must be cut back.
The metal may now be roll formed as normal.

The fabrication of the previously mentioned components may be achieved in two formats, one on site, two in the factory. Format 1. is very similar to the system used in the conventional wooden frame. All the components are laid out on a flat surface i.e. the floor. Stud number 1. Is installed in slot number 1. of the bottom plate. The tongue is bent to prevents it's accidental dislocation. The protruding piece of the plate is bent up to secure the stud. (As shown in Fig.7-8 9) The top tongue of the bottom portion of the brace with the tongue of the first noggin, is installed in stud number 1. The tongues of these are bent to secure them. The bottom tongue of the bottom portion of the brace is installed in slot 2. of the bottom plate, the tongue is bent making this portion of the frame square. Number 2..stud is installed in slot 2. of the bottom plate, the tongue is bent to secure it. The end of noggin 1, is installed in the slot of stud 2. (As shown in Fig.7-10) This sequence is continued until all studs with the noggins have been installed in the bottom plate. The bottom tongue of the top brace is fitted with the noggin in stud number 1. The top plate can now be installed.
The top tongue of the top portion of the brace with the top tongue of stud 2 are installed in the second slot of the top plate. The following studs are installed in their relative positions. When all the tongues are located they may all be bent down. The wall can now be stood up. A firm blow with a hammer on each tongue in sequence will make the whole structure firm. When the wall being fabricated is load bearing a bracket as shown in (Fig 8) could be introduced into the slots occupied by both tongues of selected studs. The bracket should be introduced from outside through the slots of the top and bottom plate to and through the service openings of the studs, the portion protruding through the service opening should be bent up to 180 degrees thus increasing the wind rating. The trusses can be fabricated in a similar fashion to the wall frame.
k" In format 2 where speed of fabrication is desirable it is recommended that the wall frame using the i previous sequence as in format 1 be fabricated in a vertical and elevated position. The bottom plate is conveyed continuously on suitably designed rollers. One operator installs the studs and braces in the bottom plate and bends the tongues to secure them while the other operator on the other side of the frame and in an elevated position installs the noggins and the top tongues of the studs in the top plate and also bends the tongues to secure them. Rollers could be designed to press the top and bottom plate firmly onto the studs and press the tongues down harder against the plates.
The bracket as shown in (Fig 8) could also be used when the trusses are placed on the wails that will support them, it could be introduced through the slots from above, where the top and bottom cores meet. The elongated tongue could be bent around the flange of the top plate on which the truss is fitted. A second bracket could be installed down through the first slot of the bottom core and the elongated tongue could be bent in a similar fashion.
When only one tongue is installed in a slot, this tongue could be slit down the center to it's base (as shown in Fig 3) both halves of the tongue could now be bent down in opposing directions.
