Definitions
- the present invention relates to a device for fastening details to walls and/or reinforcement of walls comprising wallboards, for example of gypsum, mounted to a framework, wherein the supporting parts may be studs of, for example, wood or metal.
- the device is to be positioned in the areas of the wallboard absent of framework parts.
- the traditional method to perform fastening to wallboards of, for example, gypsum may be to introduce plugs of plastic or rubber into predrilled apertures in the wallboard. These plugs are wedged when expanding and are forced against the edges of the wallboard in the aperture, for example when a screw having a larger diameter than the aperture usually provided in the plug is introduced therein. So called hollow wall screw anchors are also present, which are introduced into a small aperture and expands on the rear side of the wallboard .
- Screws having an elongated screw nut profile are also present.
- the screw nut profile may be positioned parallel to the screw and, when brought through the wallboard, extended perpendicular to the screw to receive support from the rear side of the wallboard.
- the invention can be limited to a similar range of application, which is indicated essentially with reference to Fig. 20, 21 , 22, 23.
- One major drawback with the devices according to prior art is that they do not tolerate large forces before the material of the wallboard is breaking, because of the use of only one part of the wall.
- the studs When more rigid walls are required than normally the studs are ar- ranged closer. Usually this imply a distance between the studs of 40cm. To reinforce present walls removal of one wallboard is required for opening the wall to enable the introduction of more studs, which then are coated with a wallboard of normal quality. Alternatively more rigid special wallboards present on the market are selected. Then, the original distance between the studs can be used, which usually is 60 cm. Also in this case one wallboard is removed. Yet another manner is to provide the wall with an additional standard wallboard. This imply that, for example, the length of a bathroom wall usually is reduced by two times the thickness of a wallboard, which in a normal case results in two times 13 mm, i.e. 26 mm.
- One object of the present invention is to enable larger loads on fastening means than possible with present devices, and to enable reinforcement of the wallboards of a wall.
- the reinforcement device may be used for fastening exclusively or reinforcement exclusively or in combination, for example, when particularly large stress is to be managed.
- the present invention uses the fact that, for example, a wall of gypsum wallboard mounted on a framework of studs comprises one wallboard on each side of a stud.
- the reinforcement device is in its most simple embodiment a cylinder adapted to reach through one of the wallboards from its outer side and through the space between the wallboards, which space is a result of the stud, to the inner side of the opposite wallboard. In this position the cylinder may be fastened by the means of a glued joint.
- a fastening means having a lever substantially increasing its ability to bear loads mounted to the free end thereof. If the direction of the forces is in- creased towards a vertical direction the importance of the lever-forming design of the cylinder is increasing, especially when mounted in a substantially vertical construction.
- the ability o the cylinder to handle forces is limited by the strength of the glued joint at the opposite wallboard and the size of the contact surface of the lead through of the front wallboard. When loaded until collapse the glued joint is breaking and/or the material at the inlet of the wallboard is crushed. The distance between the wallboards can also be of importance.
- the lever is increased with the distance, which results in a more extensive resistance.
- the cylinder must be rigid to avoid bending thereof. Further, the cylinder may be hollow in its length and provided with holes through the portion of the surface thereof, positioned in the space of the wall.
- an elastic fabric or film may further be positioned around the cylinder, which functions as a mould for expanding substances injected into the cylinder upon requirement. These force their way out through the holes and fill the mould surrounding the cylinder, wherein a rigid body casting the cylinder and sticking to and filling between the wallboards is obtained.
- the device may be regarded as a cylin- der with a first and a last portion having a somewhat larger diameter than the intermediate portion.
- This design is used to enable for the wire cloth to be winded up on the intermediate portion, wherein the wire cloth can be brought through the aperture arranged in the outer wallboard in the mounting procedure.
- the performance is increased with increasing end diameters of the cyl- inder.
- the glued end of the cylinder may in every embodiment be bordered for improved adherence.
- the cylinder does not have to be surrounded by the wire cloth. Instead a space of desired dimensions can be formed in the cur- rent medium, which space is adapted for the current design of the reinforcement device.
- an elongated plate is mounted in the end of the cylinder, which is to be glued to the opposite wallboard.
- a further elongated plate is enclosed, which is unattached and thread onto the cylinder shaft. This plate can then be pulled towards the back side of the first wallboard and glued thereto. This will increase the strength of the wallboard and, thus, the loading capacity.
- the plates can either be positioned opposite each other, or with 180 degrees of displacement, and then be turned to an optional position in a full circle of 360 degrees as a combined unit, dependent on the direction and size of the current forces and how these, in each case, are handled in the best manner according to calculation.
- the reinforcerhent device can be provided with the wire cloth, and thereby with reinforcing fillings between the wallboards.
- the portion of the cylinder not glued to the rear wallboard and the aperture through the wallboard may be formed somewhat conical.
- the gap formed thereby may then be filled with a hardening joint sealing compound.
- All cylinder tubes of fastening devices adapted for injection may be provided with an adapter unit between the internal cylinder area and a hole adapted for a screw after injection of, for example, an expanding substance.
- the device may in some embodiments, especially as a straight cylinder (12) and (15) or having a reel shape (18), also be applied in solid materials, such as light concrete or hollow bricks.
- the devices are then glued to the surrounding material in the entire length of the device, or a desired and possible portion thereof.
- one construction part may be excluded, for example a cylinder, which enable fastening to the rear wallboard. Instead a more traditional reinforcement of the front wallboard may be used.
- a fixing device associated to the device may be used. This comprises of a substantially circular cone having a peg, which can be inserted in the aperture 16.
- the cone is provided with a larger diameter than the device so that it is supported by surrounding surfaces, to which it temporarily can be fastened by the means of glue and/or a pin.
- a spacer may also be provided with filling spacers to compensate for differences in diameter.
- Such a spacer may also be mounted permanently. " If there is space filling means, for example mineral wool insulation in the wall, and removal of this is desired a space clearing tool developed for the device may be used.
- the tool comprises a bar having a pivoted front portion provided with a cutter. This tool is inserted through an aperture in the wallboard and is heavily rotated, for example by the means of a drilling machine.
- the pivoted portion is extended and clears a space having a radius corresponding to the length of the pivoted portion and a space length corresponding to how far the tool is inserted.
