Description

Brick Line Block

Field of the invention

The present invention relates to a brick line block for mounting on a corner profile to hold a brick line.

Background of the invention

Corner profiles are vertical posts that are used by bricklayers to assist in aligning bricks as they are being laid. Profiles serve to ensure that bricks making up a corner of a structure are vertically aligned, and they are also used to support brick lines that serve to ensure that the courses of bricks are laid horizontally.

Profiles are metal box sections of square cross-section with external dimensions of typically 50.8 mm (2 inches square). The profiles may be positioned in different ways relative to the courses of bricks being constructed. In some cases, when constructing an external corner, the profile 10 is positioned relative to the bricks 12 in the manner shown in Figure 1 of the accompanying drawings, but such positioning interferes with the pointing of the corner bricks. Instead, the configuration shown in Figure 2 is commonly preferred, where the profile 10 is positioned with one of its corners facing the corner to be constructed. The present invention is concerned with a brick line block intended for use with a profile that is positioned in the manner shown in Figure 2.

Various ways are known for securing such profiles in their desired position, but these need not be described in detail in the present context Brick line holders for such profiles are also known and are constructed as a clip with guide surfaces for the brick line and sometimes with cleats for anchoring a brick line.

As shown in Figure 2, the brick line 15, which is represented in dotted lines, is required to be spaced from the edges of the courses under construction, in order to avoid the brick line being deflected by contact with the bricks. Because of this, the positioning of the corner brick can only be judged by eye and, in particular at the corner edge, this can result in visible misalignment of the bricks. -2 -

Object of the invention The invention seeks therefore to provide a brick line block for mounting on a profile that ensures exact vertical alignment between bricks in different courses

Summary of the invention

According to the present invention, there is provided a brick line block configured to fit over a profile and firmly clamp onto the profile, wherein the block is provided with guide surfaces for positioning of a brick line and has on an inner side first and second surfaces lying in mutually perpendicular planes to contact two external surfaces of the profile, characterized in that an outer side of the block is formed with third and fourth surfaces that lie in planes respectively parallel to the planes of the first and second surfaces, against which third and fourth surfaces two sides of a corner brick being laid may be abutted to locate the corner brick in a predetermined position relative to the profile.

A cleat may be provided on the outer side of the block to permit anchoring of the brick line.

In some embodiments, the block may a constructed as a collar, to surround the profile on all sides. In such an embodiment, a clamping screw may be provided on the collar at a corner diagonally opposite the corner defined by the first and second surfaces.

The collar, in some embodiments, may comprise a square tube and two flat plates may be secured externally to two sides of the tube at one of the corners, the third and fourth surfaces being defined by lateral edges of the two plates.

The two plates may have upper regions that project beyond an upper edge of the square tube, and a groove of predetermined depth, and conveniently located level with the upper edge of the square tube, may be formed in the lateral edge of each upper region to serve as a guide surface for the brick line To enable the block to be used when constructing internal corners, a second groove of predetermined depth may be formed in a face of each upper region. -3 -

It is desirable for the block to have an axial length corresponding to the desired height of the courses of the bricks to be laid In this way, it may be used as a gauge to mark off on a profile the correct height at which the different courses should be laid.

Detailed description of the drawings

The brick line block 100 shown in Figures 3 to 6 is constructed as a collar dimensioned to fit over a corner profile 10 in the manner shown in Figure 7 and 8. The block 100 is constructed from a tube 14 of square cross-section and having internal dimensions greater than 50.8 mm. One of the corners of the tube 14 has a chamfered edge 16. The two internal surfaces of the tube 14, designated 18 and 19, that meet at the chamfered corner, are clamped against two sides of the profile by a clamping screw 20 engaged in a nut 22 secured, such as by welding or riveting, to the opposite corner of the tube 14. A rod 24, serving as a cleat about which a brick line can be wound, is screwed to the tube 14 above the nut 22. Slots 26 are cut into the other two corners of the tube 14, to guide a brick line around the exterior of the block 100.

Two plates 30 are each secured by a respective screw 34 and dowels 36 (see Figure 6) to the tube 14 at the chamfered corner between the internal surfaces 18 and 19. -4 -

The plates 30, 32 are accurately machined and positioned on the tube 14 so that their lateral edges 33 and 35 lie in planes that are parallel to the planes of the surfaces 19 and 18, respectively.

The plates 30 and 32 project beyond the upper edge of the tube 14 and their projecting upper regions 40, 42 are formed with grooves 44, 46 in their lateral edges that are level with the upper edge of the tube 14 These grooves 44, 46 also wrap around the upper regions 40, 42 of the plates 30, 32 to extend along the front face of each plate.

The grooves 44, 46 serve as guide surfaces for brick lines which wrap around the block in the manner shown in Figures 7 and 8. The plates 30 and 32 having an angled upper edge to allow a clear path between the grooves 44, 46 and the slots 26 in the tube 14.

is To enable the brick line block 100 to serve as a gauge, the distance from the upper edge of the tube 14 to the lower edge of the plates 30, 32 is set to be the same as the desired height between the courses of the bricks to be laid In practice, profiles are mounted at opposite corners of a wall to be constructed and a mark is made at the upper end of each profile to indicate the level up to which the wall should be constructed. The brick line block 100 is next fitted to the profile and, while positioned level with the mark, a second mark is made level with the bottom edge of the plates 30, 32. The brick line block 100 is now moved down to the new mark and the process if repeated until the profile carries marks at each of the levels to be aligned to the top of a course of bricks The brick line block 100 is next clamped at the location of the lowermost course to be constructed and a line is passed between the grooves 44, 46 of the brick line blocks at the opposite ends of the wall to be constructed. The corner brick is next positioned in contact with the lateral edges 33, 35 of the plates 30, 32 and a course of bricks is laid in a straight line, using the brick line as a guide. Once the top course of bricks has been laid, the brick line blocks 100 are moved up to the next mark on the profiles and the process is repeated.

When constructing an external corner, as shown in Figure 7, the lateral edges 33, are used as abutment surfaces for the corner brick 12 and the grooves 46 in the lateral edges are used as guide surfaces for the brick line 15. The brick line block can however -s -additionally be used in the manner shown in Figure 8 to assist in the construction of an internal corner. In this case, it is the faces of the plates 30, 32, that serve as abutment surfaces for the corner bricks 12 and the section of the grooves 44, 46 in the front faces of the plates 30, 32 that serve as Ode surfaces for the brick line 15 In all cases, the depth of the grooves 44, 46 should be sufficient to accommodate the thickness of the brick line 15 and additionally to provide a small space between the brick line 15 and the course of bricks to be constructed.

lo It is not essential for a brick line block 100 to be formed as a one-piece collar, as it may alternatively not wrap around the profile or be constructed of two parts assembled to one another. It will be clear to the person skilled in the art that various other modifications may be made to the described embodiment of the invention without departing from the scope of the invention as set out in the appended claims.
