DESCRIPTION OF THE INVENTION

In Figures 1 and 2, there is shown a bricklaying profile 10 in accordance with the present invention. The bricklaying profile 10 of Figure 1 comprises a corner profile member 12 in the form of a right angle section member.

The corner profile member 12 is as can be best seen in Figure 1, arranged to be mounted in upright manner on a surface and when upright has a first lower end 13a and a second lower end 13b.

The corner profile member 12 comprises a pair of side walls each having an L-shaped notch 14 formed into the upper end 13b thereof (see Figure 4). The notch 14 of one wall is deeper than the notch 14 of the other wall so that, in use, connection means mounted in the notches 14 do not interfere with one another. The apparatus of Figures 1 and 2 further comprises a pair of elongated brace members 16 each formed in two parts. There is an inner part 16a which is slidably received in an outer part 16b. The inner part 16a may be moved relative to and within the outer part 16b to adjust the overall length of the brace 16. A screw adjuster 18 or the like is provided for holding the parts of the brace 16 in any desired position relative to one another. Each brace member 16 comprises a first end 19a arranged to be mounted in spaced manner from the lower end 13a of the corner profile member 12 when the latter is upright, and a second end 19b arranged to be connected to the upper end 13b of the corner profile member 12. As shown in Figure 3, the upper end of each brace member 16 comprises a flange 20 which is apertured.

A connection means in the form of a connector 22 has a shank 24 having a threaded end portion. The shank 24 is located in the aperture of the flange 20. The shank 24 is retained in place by means of an inner integral annular portion 25 formed with the shank 24 and a nut 26 located on respective sides of the flange 20, The shank 24 has a ball end (not shown) which is rotatably mounted within a socket 27 having a hexagonal nut 28 formed therewith. A further shank 30 projects from the nut 28. The shank 30 has a pair of spaced end plates 32 formed therewith.

In use, the shank 30 enters a notch 14 and the plates 32 are located adjacent respective sides of the respective wall 14 of the corner profile member 12. The ball and socket connection of the connector 22 enables variations in the angle between the brace 16 and the corner profile 20 to be taken up by adjustment of the angle between the shank 24 and the socket 27.

At its end 19a, each brace 16 comprises a foot 32 which has a bracket 34 mounted thereon (see Figure 5) . The bracket 34 contains aligned apertures which mate with a corresponding aperture in the lower end 19a of the brace 16.

Thus, the bracket 34 can be pivotally coupled to the lower end 19a of the brace 16 by means of a bolt 33 or the like. This enables the foot 32 to pivot relative to the brace 16. As can best be seen in Figure 3, the foot 32 is pointed at 32a and has a generally triangular shape. This means that in soft ground as is often encountered during building, the foot 32 can be pivoted so that the point 32a faces downwardly as shown in Figure 7. The point 32a can then be driven into the ground to hold the lower end of the brace 16 in place.

Where the ground is hard, or where the lower end of the brace 16 rests on an adjacent wall, the foot 32 can be used in the position shown in Figure 6 in which it rests on the ground. In this case, it can be weighted down such as with bricks or the like.

Further, to ensure that the profile 12 is upright, it preferably includes a spirit level 36 (see Figure 1) which may be at head height in use. Still further, as can best be seen in Figure 1, the corner profile member 12 may have a line block 38 attach¬ ed thereto. The line block 38 is arranged to support a line so as to guide a bricklayer as to the correct height for laying bricks in a row. Further, the line block 38 is arranged to be slidable along the corner profile member 12 and to be retained at any desired height by frictional engagement with the corner profile member 12. Further, the line block 38 comprises pairs of studs 40 around which a line may be wound a number of times to take up any slack in the line.

Further, the brace members 16 can be connected to the corner profile member 12 externally of the corner defined by the corner profile member 12 as shown in the drawings, to assist in laying an outwardly directed brick corner within the profile.

Alternatively, the brace members 16 may be connected to the corner profile member 12 internally of the corner defined by the corner profile member 12 to assist in laying an inwardly directed brick corner externally of the profile.

The latter type of arrangement is illustrated in Figure 8, but in this case and in Figure 9, the bricklaying profile 10 has mounted on the corner profile member 12 an assembly 40 comprising a slidable right angled member 42 arranged to be secured at a desired height by means of a threaded stud 44 mounted in a threaded aperture in the member 42 and arranged to be turned by hand to frictionally engage the corner profile member 12 to

OMPI hold the member 42 at a desired height. An elongated substantially horizontal trammel arm 46 is attached to and extends away from the slidable member 42. The trammel arm 46 is telescoped and comprises an outer portion 46a slidably received within an inner portion 46b. A wing nut 47 or the like is provided in the inner portion 46b for frictionally engaging the outer portion 46a to fix the overall length of the arm 46. The arm 46 is connected to the member 42 by a pivotal connection which allows the arm 46 to be pivoted horizon¬ tally. The arm 46 is also supported by a rod 50 or the like extending from the member 42 to the inner portion 46b of the arm 46. The inner portion 46b of the arm also has a level indicating means such as a spirit level 56.

Means is preferably provided for adjusting the length of the rod 50 to adjust the level of the arm 46. For example, as shown, the rod 50 may comprise a threaded portion inserted in a threaded socket connected to the arm 46.

The slidable member 42 has an upwardly projecting threaded stud 58 at its upper end at the junction between the sides and a corresponding downwardly projecting threaded stud 58a at its lower end. The inner end of the arm 46 is pivotally engaged on the downwardly projecting stud 58a and is retained thereon by means of a nut 60 while an aperture at the inner end of the arm 50 is pivotally engaged with the stud 58 and retained thereon by means of a nut 60. In use, the outer free end of the arm 46 is swung around at a desired level on the pivotal connection to the slidable member 42. The arm 46 is swung around as work proceeds in laying a row of bricks and its free end describes a circular path for any given degree of elongation of the outer portion 46a which guides a brick layer in constructing a curved wall. The corner profile member 12 can be used to form a corner profile at high levels by lifting it up and securing it in place on already laid bricks using a clamp 62 as shown in Figure 10.

Typically, a corner profile member 12 would be about 2.5 metres high. Thus, if it is desired to form a corner above this height, the corner profile member 12 can be lifted up and secured as shown in Figure 10, by placing a clamp 62 across a wall of the profile member 12 and a face of an already laid wall and then tightening the clamp 62. This -supports the profile member 12 while it is used as a corner profile at high levels. Modifications and variations such as would be apparent to a skilled addressee are deemed within the scope of the present invention. For example the corner profile member 12 could be marked at intervals corresponding with a particular gauge of brickwork. The marking could be in the form of recessed lines. In the latter case, the inner end of the arm 46 could be provided with a pointer arranged to engage with the gauge marks so as to provide a ready indication of the correct height for each level as determined by the gauge. Also, the arm 46 may be provided at its free end with a plastics member comprising a vertical downwardly depending flange and a horizontal forwardly projecting flange. These flanges form a right angle and can engage with the upper, adjacent corner of a row of bricks being laid to provide an accurate height indication.

Also, the arm 50 could be provided with a turnbuckle to enable the length of the arm 50 to be varied.
