Description

APPARATUS FOR HOLDING AND ANCHORING REFRACTORY CONCRETE
TYPE LININGS
This invention relates to refractory concrete type linings for furnaces and in particular, relates to the component devices or apparatus for holding and anchoring the lining to the surface of the furnace.
BACKGROUND OF THE INVENTION
Although the following description refers generally to the utilisation of a component device for anchoring a refractory concrete type lining to the surface of a furnace, pipes or the like, the anchoring device can also find utility in any situation where concrete type linings are required to be applied to similar or other type surfaces. Therefore, reference to refractory concrete type linings is also meant to encompass any similar material where, by suitable modification if necessary, the invention can also be utilised.
Such refractory linings are used in industry for a variety of reasons including thermal insulation, abrasion resistance and general steelwork protection for vessel components in a variety of process applications.
Due to harsh conditions within a furnace, the linings need to be replaced as they deteriorate over time. The concrete type linings are generally constructed with the use of individual anchors which are fitted to the internal wall surface of a furnace or on the outside surfaces of pipes.
hi some cases, the individual anchors are welded to the internal surface of the furnace or outside surface of the pipes and need to be removed and replaced when it is time to replace the lining. It has been found that it is. inconvenient to remove and install the welded anchors and it would be advantageous to provide an anchor apparatus which enabled the lining to be applied and anchored more efficiently. OBJECT OF THE INVENTION
The present invention has therefore been conceived out of the need to provide a means whereby thin refractory concrete type linings can be adhered to surfaces of furnaces, pipes or the like utilising anchor apparatus which provides greater efficiency in applying the anchoring apparatus thereto. At the very least, the invention provides an alternative to presently known anchors for applying such refractory concrete type linings.
DISCLOSURE OF THE INVENTION
According to the present invention there is provided an anchor apparatus for refractory concrete type linings, said apparatus being used as one of a plurality of anchor apparatuses to adhere said refractory concrete type linings to surface of furnace, pipe or the like, said apparatus including a cleat member adapted to be fixed to the surface to which the lining is to be applied and a one piece anchor member having a foot portion adapted to be received in the cleat member and at least one ear extending away from the surface to which the lining is to be applied, wherein the foot portion has a deflection therein such that the foot portion has a spring action type grip between the cleat member and the foot portion.
Preferably, the anchor member has two ears and is made from a single elongate length of material.
In another preferred form, the anchor member is a two piece arrangement such that elongate anchor ears are fitted to a base foot which is received in the cleat.

Fig. 10 is plan, side and end views of the anchor apparatus of Fig. 6 shown in assembled state.
BEST MODE OF CARRYING OUT THE INVENTION
Referring to Figs. 1 to 5 of the drawings, there is illustrated an anchor device 10 of a preferred embodiment which is for use with refractory concrete type linings. A number of the devices 10 are welded to a furnace wall and a refractory type lining is applied to the wall over the devices 10. The device 10 has a cleat 11 which is welded to the wall and is basically U shaped with the ends 12 being welded to the wall. The cleat 11 when so fixed to the wall provides an open channel 13 into which an anchor 14 is received with an interference fit.
The cleat 11 can be manufactured by various means such as casting or pressing from a range of various metal alloys. The shape and size of the cleat can be varied appropriate to the use application.
The anchor 14 in this embodiment is a one piece anchor made from a single length of steel bent to shape as seen in the drawings. The anchor 14 has two free ends 15 with a corrugated foot 16 which is adapted to be driven into the channel 13 of the cleat 11 and is held in place by spring action type grip between the foot 16 and the cleat 11. The anchor 14 can be made in various grades of material and in a variety of shapes. The foot 16 is specifically manufactured with a corrugation 17 to give the spring type grip when the anchor is driven into the channel 13.
One advantage of the anchor device is that the cleats can be relatively easily welded to the wall without the free ends of prior art anchor devices providing difficulties. The anchor 14 is easily fitted to the cleats 11 in an interference fit usually by means of a hammer or such like device. The anchor 14 can also be easily removed when the lining is replaced and the cleat can remain in place if desired for the next installation. Another advantage is the flexibility of the anchor when installed which provides greater prevention of damage to the lining when in use.
Another anchor device 20 of second preferred embodiment is illustrated in Figs. 6 to 10 of the drawings. The anchor device 20 is similar to the first described embodiment in that it has a cleat 21 and an anchor 22. The difference is that the anchor 22 has a corrugated base plate 23 replacing the foot 16 of the first embodiment. The anchor 22 is threaded through a hole 24 in the base plate 23 with the shape of the hole 24 and the anchor 22 causing an interference fit between them to enable the anchor 22 to remain upstanding.
