Abstract

A coping stone and an intermediate moulded building block are integrated during manufacture in the mould, the coping overlaps the intermediate block on both sides, and the whole is laid as the finishing building operation thus reducing the steps necessary to build a wall. <IMAGE>

Description

SPECIFICATION Improvements or modifications relating to boundary or garden walls the integrated coping stone This invention relates to building bricks and mould able building blocks, and has particular reference to the joining of intermediate mouldable building blocks with coping stones during the manufacturing process.

It is customary at present, to add a coping stone to boundarywalls during the "finishing" operation, for decorative effect.

Unfortunately, coping stones as manufactured in the present art, and not according to this invention, are thin and delicate and easily broken,-- either during manufacture, during transit, or by the builder himself during the building process.

More-over, asthe builder progresses along the top of the wall, applying the coping stones, they tend to get out of sequence with the intermediate blocks which they are covering, owingto the application of mortar between the joins. The over-laps or overhangs, when they are out of sequence with the underlying intermediate building block, do not present an attractive sight.

The length of the strips of coping as manufactured at present, bears no relation to the length ofthe top surface of the brick or block of the top surface ofthe brick or block which they are meant to cover, there being so many diversities in the sizes of the bricks or blocks currently being manufactured.

With the passage of time, and the vagaries of the weather, coping stones as attatched according to the previous art, inevitably work loose and constitute a danger. Re-attatchmentthen becomes necessary, entailing the cost of added mortar and the builder's time, if notthe cost of new coping stones. This invention introduces a new concept designed to do away with all the aforementioned drawbacks of the former art, by the introduction of the Integrated Coping as partly described heretofore, wherein an intermediate building brick, oran intermediate moulded building block, is joined in the mould, during manufacture, with a coping stonewhich would otherwise require to be joined separately, at a later stage in the building process.The coping stone overlaps the intermediate building block it is covering, and with which it is now integral, i.e. it overhangs it on both sides, as in the prior art, except that now, the coping is integral with the intermediate building brick or intermediate building blockaccording to this Invention.

When manufacturing the Integral Coping bythe use of existing fibre-glass or metal moulds, it would simply be necessaryto remove the dividing wall between the coping mould and the main body mould, and fuse the two together. Butwhen manufacturing by the machine method it would be necessaryto produce specificallyfabricated mould-boxes, tamper-heads, and patterns.

In orderto integrate an intermediate building brick asshown in Fig. 1 B. ofthe accompanying drawings, with a coping stone as shown in Fig. 1A. of the drawings the pallett as shown in Fig. 3. is, in fact the coping mould, which will contain the mix which wili form the coping stone. Fig. 4. showsthetamperwhich firms the mix in the coping mould. Thetamperswill require to be fractionally smallerthan the moulds in orderthatthey may enter in. The mould-boxas shown in Fig. 5. then comes to rest overthe coping mould and is filled with the desired mix. Now the appropriately sized tamper-head, namely that as shown in Fig. 6.

tamps down the mix in the mould-box, and the brick emerges, integrated with its own coping stone.

Attractively curved copings may be formed by incor porating a curve in the base of the coping mould.

Another method may also be used to produce a brick or block with an Integral Coping as shown in Figs.

7,8 & .

Fig. 7. is the pallett, but it does not form the coping in this instance.

Fig. 8. is the mould box, and it comes to rest on the pallett and is filled with the desired mix. The specifical ly fabricated tamper head, Fig. 9. tamps down the mix, and the brick or block emerges with an Integrated Coping stone.

in order to accommodate the more decorative screen-walling block as shown in Fig. 11. it would be necessary to integrate the coping stone as shown in Fig. 1 OA. of the drawings, with the intermediate block as shown in Fig. 1 OB.

In this instance the pallett requires to have a "stepped-down" profile to accommodate the overlaps ortheoverhangs ofthe coping.

The mould box, Fig. 14. which itself requires a "stepped-down" profile in order to sit snugly upon the pallett base (Fig. 13.) is then lowered into position and filled with the desired mix, and the specifically designed tamper head, with the necessary "steppedup" profile which accommodates the projections of the coping on the upper surface of the block, comes into play, and firms down the mix. The patternforming projections are accommodated through apertures in the pallet base, including the coping, and the tamper head is specifically adapted to accommodate the pattern-forming projections whilst tamping down the mix. The pallett is then lifted clear of the projections, and the block is fed out of the machine.

1. ACoping Stone and an intermediate mouldable building brick or block, both formerly of the prior art, are integrated during manufacture in the mould, according tothis Invention. As in the priorart,the coping stone overlaps on both sides, the intermediate building block which it is covering, but with which it is now Integral, and the whole is laid as one "finishing" building operation, thus reducing the steps necessary to build a wall.

2. An Integrated coping stone and intermediate building block as claimed in Claim 1. which is manufactured from brick. concrete, aggregate, simulated stone, or other mouldable building material.

3. An Integrated coping stone and intermediate building block as claimed in Claim 1. in which patterns, which may penetrate the blockto the other side, are carried to the Integral Coping.

4. An Integrated Coping Stone and intermediate building block substantially as hereinbefore described with reference to the accompanying drawings.

Newclaimsoramendmentstoclaimsfiled on Superseded claims 1-4 New or amended claims :

1. According to the present Invention, a Building Element (fig. 2.) is formed by integrating (during manufacture in the mould) a Coping Stone (fig. la. of the drawings) and an Intermediate Building Block (fig 1 b of the drawings) As in the prior art, and also according to this Invention, the Coping Stone forms "drip-edges" or "eaves" which weather the wall.

These "drip-edges" overlap onlythe intermediate building blockwith which the coping is now integral, sincethe Element shown in Fig. 2. comprises a method of coping a single-skinned wall. A number of said Elements as shown in Fig. 2. are laid as one final "finishing" building operation forming the topmost course of the wall. The steps necessaryto build a wall are thus reduced, as are the materials required. No.

component parts cap the Element as shown in Fig. 2.

thus the Element presents a true Coping Surface.

2. A Building Element as claimed in Claim 1. which is manufactured from brick, concrete aggregate, simulated stone, or other mouldable building material.

3. A Building Element as claimed in Claim 2. in which patterns which penetrate the main body ofthe blockthrough to the other side, are carried to the Integral Coping which may be decoratively curved.
