Description

This invention relates to a method of machining mortar blanks for use in the masonry of bricks and to an apparatus for transferring a mortar blank to a masonry site.

GB publication No. 1,538,803 discloses a masonry tool which is next placed in place of a brick to be masonry. The tool comprises a handle from which the two arms extend downwards, forming mortar boundaries on the vertical seam of the brick. The arms are guided according to the previous brick. These shafts continue horizontally, delimiting the mortar boundaries for the masonry brick to the seam below the brick. The mortar can be applied as an even layer for both vertical and horizontal joints of the brick. Before laying the brick, the tool is raised.

Em. the tool does not guarantee the straightness of the wall at all due to the short guide part, and it is by no means certain that the mortar will remain on the vertical part of the joint when the device is lifted before the brick is fitted.

U.S. Pat. No. 2,648,974 discloses a masonry mold which is placed on top of a row of bricks so as to cover several successive and also parallel bricked bricks. Mortar is dispensed into the mold, in which case the mold mainly prevents the spread of the mortar and the sides of the mold act as a guide for the bricks.

In the solution according to US patent 2,648,974, the mortar must be placed separately in the end joint of the bricks as well as between the parallel bricks. In addition, the mold resting on the bricks during masonry work greatly hinders the masonry work, especially the placement of the bricks, although the mold acts as a guiding surface and helps in positioning the bricks.

The method and device according to the invention provide a decisive improvement in the above-mentioned drawbacks. To achieve this, the invention is characterized by what is stated in the claims.

The most important advantage of the invention is that the masonry work is faster and easier and the resulting brickwork is of uniform quality.

In the following, the invention will be explained in detail with reference to the accompanying drawings.

Figure 1 shows a masonry device.

Figure 2 shows a layer of mortar canceled on top of a brick layer.

Figure 1 shows a masonry device suspended on ropes 20, 21 and moves parallel to the wall to be masonry on wheels 19. The height of the device can be adjusted by locking the mutual pin of the tubes 16 and 18 by means of a pin 17 inserted into the holes 16. The guide plates 1 of the device are fixed to the tube 15 by means of a plate 14 and slides 12,13. The distance between the plates 1 can be adjusted by means of the palm 11. The mortar mold 2 is attached to the adjustable arms 7,8,9. The mortar mold is articulated to the arm 9 by a joint 4 and the mortar mold 2 rests on supports 6. When masonry is carried out, the masonry device is moved to the masonry site and the masonry mortar is dispensed into the mortar mold 2 and the mortar blank is leveled with the upper edge of the mortar mold 2. The mortar mold comprises recesses 3, at which a ridge is formed in the mortar blank. The mortar blank is turned on the lower tile layer against the abutments 10 by the handle 5. The same sequence of operations is performed with both mortar molds 2 of the device, after which the masonry device is moved forward.

The abutments 10 can be fixedly attached to the masonry walls 1, in which case, in order to move the masonry device, the masonry walls must first be rotated closer to each other from the crank 5, whereby the abutments 10 no longer reach the bricks during the transfer. Alternatively, the abutments 10 can emerge from the holes made in the masonry walls 1 and can be retracted, respectively, so that they do not impede the transfer of the device between the masonry walls. All the counterparts 10 of the same masonry wall can be bonded to each other, thus they

Figure 2 shows a mortar blank 22 turned over a previous brick layer 24, in which the ridges 23 of the mortar blank are at the joints of the bricks to be built. The masonry device has been moved forward, so that the bricks 25 can be pressed into place.

In particular, it should be noted that the invention has been described above with reference to only one preferred embodiment thereof. However, this is in no way intended to limit the invention to this example only, but many modifications are possible within the scope of the inventive idea defined by the following claims.

Claims (8)

1. A method of bricking one or more tiled wall walls was used with At least one masonry wall (1) provided with a masonry device which is mounted above the brick wall and is movable, hung on rope (20,21) and directed to because of several bricks characterized in that mortar, which is meant to masonry between brick turns, is distributed as a layer in a mortar form (2), as joined in a masonry device, which form comprises recesses (3) with division of the length of the brick and said mortar molds are turned around its hinges (4) as a mortar layer (22) on the brick row so that mortar portions of the moldings (2) depressions (3) form elevations (23) at points of the bricks end joints. 2.
