- Figure 14 is a diagrammatic view of a slab fitting to stud- work with use of fixings according to the invention.
- a T-shaped fixing 1 formed of a first strip 2 of plated steel providing in cross-section a T-head limb and a second strip 3 providing a T-stem limb, the T being invert in Figure 1.
- the limbs are connected by folding the steel double at one edge 4 of the T-head strip and then folding the steel at right angles at the line 5 joining the two limbs.
- the steel can be slit to the line 5, with alternate oppositely directed ears 6,7 being folded into the head of the T, into a toothed /castellated arrangement.
- the head limb is provided with a series of punched apertures 8 to which pointed pins 9 are fitted.
- the apertures can be circular as in Figures 1 to 3 with the pins having crimps 10 to stop them from passing straight through the apertures.
- the pins can be formed with grooves 1 1 and the apertures with indented edges 12, whereby on insertion of the pins, the edges engage in and grip the grooves, whereby the pins are retained.
- the pins can be shouldered 14, the shoulder regulating the pin's desired position with respect to the apertured limb in the same way as the crimps 10.
- the folded flange 15 can be apertured for the pin. This is advantageous in support of slab edges as referred to below.
- the head limb is provided with apertures 16 for screw or rivet fixing of the fixing.
- the stem limb can also be provided with apertures 17.
- fixings 1 For use in insulating a square section duct 21 , as shown in Figure 6, its corners are provided with fixings 1 , with flanges having the pin apertures extending downwards at the lower corners and outwards at the upper corners.
- the flanges having the pin apertures are referenced 22 at the lower corners and 23 at the upper corners.
- the fixings are screwed or riveted to the ducts via the apertures l ⁇ , 1 ⁇ F at 24.
- fixings can be attached by self adhesive pads 25 in equivalent positions.
- Lightweight insulation 26 such as made of closed cell polyisocyanurate slab, is first fitted to the underside 27 of the duct, with pins 9 being inserted laterally through the flanges 22 into the edges 28 of the slab, when the slabs are of a size to require two man operation.
- pins 9 being inserted laterally through the flanges 22 into the edges 28 of the slab, when the slabs are of a size to require two man operation.
- normally one man fitting is possible, in the following sequence as shown in Figure 7:
- Pins 9 are fitted from the inside of the flange 22 opposite from the fitter; (ii) The bottom insulation slab 26 is pressed against these pins, which support the far edge of the slab. The fitter then lifts the near edge up within the flange 22 on his side; (iii) Further pins 9 are fitted into this flange from the fitter's side, thus securing the bottom slab;
- Top slabs 33 are placed on the top 34 of the duct, with their edge faces 35 supported by the flanges 23 from which the pins 9 extend into them, please see refer to Figure 5 above;
- the self-tapping fixtures 29 each have a drill tip 74 and a self-tapping screw thread 75 projecting from a larger diameter body 76. At the tip end of the body a sealing washer 77 is provided.
- the drive head 78 has an integral washer 79, which backs another sealing washerf
- the body is marginally shorter than the thickness of the slabs, whereby when the screw are fitted, with the front washer abutting the ducting, the head washer marginally compresses the slab. The washers seal against air egress from the duct and water ingress into the slab.
- the insulation is provided as short lengths 42, grooved 43 to receive the flanges.
- a vent 44 is provided in the bottom grooved slab, with a non-return valve fitting 45. These allow any pressure air escaping from within the duct at the flanges 41 to exit from within the insulation.
- a short length 46 of capping bridges the joints at both ends of the slabs 42 and is strapped 47 on or secured with the self tapping fixtures.
- the fixing 51 is short lengths of the fixing 1 with a wire or strip 52 included in the doubled back section, to space the short fixings around the ducting's curve.
- the fixing 61 for a circular ducting 62 is of L-cross- section, with one flange 63 able to bend to the contour of the ducting and the other 64 is notched at 65 to allow the one to bend.
- the bendable flange has screw fixture points 66 and the notched flange has pin holes 67.
- the insulation 68 is grooved 69 and has a flexible outer wrapping 70.
- a fixing 61 is first secured around the ducting, with pins 9 fitted. The insulation is then wrapped around the ducting and moved lengthways until the pins engage and the end 71 of the insulation abuts the notched flange 65. A second fixing 612 is then placed around the ducting, with its notched flange against the other end 72 of the first insulation wrap. It is secured and the pins are inserted in pin holes 67 and on into the end 72. A second insulation 682 is added and the process is continued along the ducting.
- T fixings 101 with stud- work 102 for securing an insulation board 103 is shown.
- the fixings are secured top and bottom to the stud-work.
- the board is lifted into position at the top first, being pressed (i.) against the pins of the upper T-fixing.
- the bottom is then swung (ii.) in against the pins of the lower fixing.
- the fixing can have an additional flange 104 and additional pins 105.
- the invention is not intended to be restricted to the details of the above described embodiment.
- they can be of two strips, the stem limb having a small flange, via which the two limbs can be spot welded together.
- the above described fixings have been described to be metallic, they could be of plastics material, with the limbs being integrally extrusion moulded with punched apertures and the pins being injection moulded. Another possibility is for the limb parts to be moulded as just mentioned and the pins to be of metallic.
- the fixings can primarily attached with adhesive, or with screw or pop rivets, whilst being initially held in place with spaced magnetic pads.
- the attachment means can be provided as lazy Z clips welded to the ducting to define grooves facing each other - or at least facing a corner edge of the ducting. The T-fixings can then be slid in along their length.
- the pins can be factory-fitted to the fixings.
- the arrangement of the T-fixing can be modified for the upper run of the stud- work to have pins extending down from the head of the T, whereby the board can be offered up from below as in the lateral slabs show in Figure 7.
