Description

Device for Brick Layinσ
This invention relates to a device for brick laying.
Brick laying is a skilled operation requiring expertise gained from practice in order to quickly form a regular and solid wall from bricks and mortar. However, amateur brick layers often wish to build a wall without hiring the skills of a professional brick layer. The skill involved in brick laying is needed due to the fact that it is difficult to get a regular spread of mortar between the bricks and if initial rows of a wall are not regular the wall will become unstable as it grows .
During the setting time of the wall, when it is under construction, the wall is very unstable, completely lacking in strength and relies on the eye of the brick layer and his dexterity in order to achieve a level and strong finished article.
Also when building a wall the building must be stopped at a specific height as the weight of the bricks at this height will compress the lower levels of mortar. This is a problem that both professional and amateur brick layers encounter.
According to the present invention there is provided a bricklaying device having first spacer member for location between vertically adjacent bricks and a second spacer member, shaped for location between horizontally adjacent bricks.
The first spacer member may be a closed peripheral wall.
The second spacer member may be in the form of a projection which projects as a continuation of the peripheral wall.
Preferably, the peripheral wall is of rectangular form.
Preferably, the peripheral wall has means of allowing the passage of mortar through the wall. Preferably, the means of allowing the passage of mortar are in the form of longitudinal slots.
Preferably, there are provided two second spacer members projecting from the peripheral wall in a common direction.
The peripheral wall may be collapsible for easy packaging of the device, this may be achieved by having weakened corners between adjacent sides of the device.
The peripheral wall of the device may be of dimensions smaller than a standard brick.
According to a second aspect of the present invention there is provided a method of building a wall comprising disposing spacer devices between adjacent bricks in the wall, wherein the spacer devices are in accordance with the first aspect of the present invention.
The method may include disposing a number of the devices in a line with the second spacer members projecting alternately up and down thereby spacing the bricks positioned immediately above and below the line of devices.
The method may, alternatively include disposing a number of the devices in a line with their projections projecting in a common direction between horizontally adjacent bricks.
A device may be disposed centrally against a brick with its projection member projecting between two horizontally adjacent bricks.
Preferably, the devices are applied to lower bricks after mortar is placed thereon.

Figure 14 is a perspective view of the device of Figure 11.
Referring to the drawings a first embodiment of a device 1 for use in brick laying is shown in Figures 1 to 5. This device has a rectangular peripheral wall 2 formed of a thin polypropylene derivative. The rectangular peripheral wall 2 is formed of two short sides 3, 4 and two long sides 5, 6 formed of rectangular sheet material which are joined at corners 9 with the flat surfaces of the sheet material vertically disposed providing the rectangular peripheral wall 2 with vertical strength in order to support a brick 12 without collapsing. The walls 3, 4, 5 and 6 of the rectangular peripheral wall 2 have a height of approximately 10 mm. The long walls 5 and 6 have a length of approximately 110 mm.
Each of the long walls 5 and 6 has a projection 7 projecting from the walls 5, 6 in a direction orthogonal to the combined rectangular cross-section of the four walls 3, 4, 5 and 6 such that the projections 7 are a continuation of the sheet material from which the walls 3, 4, 5, 6 are formed.
In this embodiment the projection 7 is of a rectangular form with two parallel walls 15 and 16 and an inverted V shape 18 removed from the rectangular projection 7 resulting in two pointed teeth 8. Each of the teeth 8 has one angled wall and one wall 15, 16 forming a right angle with the base of the long wall 5 or 6 from which it projects. A rectangular slot 11 is provided centrally at the base of each of the short walls 3 and 4 and similar slots 11 are provided at the base of each of the long walls, one between each projection 7 and each end of the wall 5 or 6.
At least two of the corners 9 of the rectangular peripheral wall 2 are weakened as shown in Figure 4 to form a hinge 10 which enables the rectangular peripheral wall 2 to be flattened to a parallelogram shape by bending at two diagonally opposite corners 9. This is particularly useful when packaging the devices 1 in bulk.
In the use the devices are placed between adjacent horizontal rows of bricks 12 in the construction of a wall. The long walls 5 and 6 of the devices are placed parallel to the length of the bricks 12. The projection 7 is placed between adjacent bricks 12 in a horizontal row.
In Figure 8 an arrangement of devices in a vertical wall is shown in which the devices are all placed are all placed with their projections 7 pointing downward with one device 1 centrally beneath each brick. An alternative arrangement is shown in Figure 6 where devices 1 are placed in alternate orientations such that the projections 7 are projecting downwardly and upwardly alternately in a horizontal row. The arrangement of Figure 6 provides additional support for the bricks 12 and may be used before familiarity is obtained with the devices 1. The devices 1 are of a width (the length of the short wall 3, 4) which is less than the width of a brick 12. The length of the devices 1 is such that two devices 1 fit within the length of a brick 12 such that the alternate arrangements shown in Figure 6 can be used if necessary. However, it is possible to use the devices 1 with other shapes of bricks or blocks other than the standard sized building brick 12.
Figure 9 shows an arrangement which can be used for the first row of bricks where the devices 1 are used with their projections 7 pointing upwardly between bricks 12. This enables the flat top 17 of the devices to be placed on the ground or the surface on which the wall is to be built.
The devices 1 have slots 11 such that the mortar can pass around the device 1 when it is being used. This ensures an even spread of mortar around the device 1. Similarly the inverted V shape 18 in the projections 7 enables the projection 7 to be placed in the mortar with the least disturbance to the mortar. The teeth 8 of the projections 7 can be rounded for safety.
In use when building a wall, a row with half a brick 12 at the end of a row occasionally occurs where a straight end of the wall is required. In order to support the half brick a device 1 can be used with its projection 7 pointing upwardly below the half brick opposite a device 1 with its projection 7 pointing downwardly disposed above the half brick.
Additionally, if an end brick of a top row of bricks is required to support a paving slab or other article above the top row of bricks, a device 1 can be used with its projection 7 removed as a simple spacing device between horizontal rows . The devices 1, 21, 31 remain embedded in the mortar as it dries and are not removed from the wall .
In the second embodiment shown in Figure 10 a similar device 31 has apertures 12 through which the mortar can flow. These apertures 13 act in the same way as the slots 11 in the first embodiment.
A third embodiment of the present invention is shown in Figures 11 to 14. This embodiment is a simplified version of the device 21 with a rectangular peripheral wall 22 with two short walls 23 and 24 and two long walls 25 and 26. A projection 27 projects from each of the long walls 25 and 26. Projection 27 is of rectangular form of a width of approximately 10 mm. Two of the corners 29 which are diagonally opposite each other can be weakened or hinged in order that the device 21 can be flattened for packaging purposes.
Improvements and modifications can be made to the foregoing without departing from the present invention.
