Bricks will interlock with each other on top and bottom and fixed to a raw wall using the proper mounting brackets with adjustable screw.
Description
BACKGROUND

Decorative masonry façades are often used in place of load-bearing brick for lower cost and ease of construction. Prior art decorative masonry façades are known in the patent literature.


US20100031592 describes composite cladding panel comprising an internal skin and an external skin with insulation material there between, one of the skins having a plurality of tongue and mortise blocks mounted directly to the panel by a mounting means to form a cladding. While it uses interlocking mortarless cladding, it is thick and requires a flat substrate wall.


US20020056237 describes a wall structure comprising a plurality of columns of preformed, lightweight, stacked blocks, with the columns of blocks connected to each other by a plurality of elongated, vertically oriented, support beams. This can be very expensive in material cost, requires a flat substrate wall, and requires a large amount of labor.


U.S. Pat. Nos. 6,393,791 and 6,442,913 describe a freestanding wall constructed by erecting at least two upright supports. The upright supports are either posts or columns. Upper and lower horizontal structure members are fastened to the upright supports. Cladding is attached to at least the front and optionally the back of each vertical intermediate framing member to conceal each vertical intermediate framing member. This also requires a flat substrate wall, and is expensive with regard to workmanship.


US20220243481 describes a frame for retaining one or more masonry slips, the one or more masonry slips each having two slots formed on two sides thereof, so as to thereby hold the one or more masonry slips within the elongate channel when said one or more masonry slips are present. This requires a flat substrate wall, and has a high material cost.


The prior art requires flat wall and involve extensive metal or plastic mounting profiles. Thus, improved solutions are needed.

DETAILED DESCRIPTION

Brickwork is one of the finest building material for cladding and facade; however, it is expensive in material and workmanship. This patent presents a cost effective alternative, but still appears as brick façade. It uses less material, produced in mass production pavement press, and it is fast and easy to install without mortar with easy alignment and mounting to the substrate wall. The cost of the brick reduced by making it thin, hence less material, and producing using a cost effective mass production pavement press machine. Workmanship reduced by having interlocking feature and easy adjustable bracket and screw mounting without the need of pre-plastering. Those features together will make a cost effective solution without losing the classic look.


The invention is a mortarless thin interlocking cladding bricks designed to be made using high production, cost effective interlock pavement press with means of fasting to the substrate wall. It consists of tongue and groove along the direction of pressing with slot in one side to insert mounting bracket to screw fasten it to a substrate wall with the ability to adjust and align. Depending on the height of the brick, it can be produced in singles or multiples and be split post-curing. It is designed to be cost effective in material and workmanship.


In some parts of the world, building is constructed using concrete column, beams and floor slap, and then external and internal walls built using raw blocks, which requires cladding in the exterior and plastering in the interior. In many cases the external wall are not perfectly vertical nor flat which needs to be plastered before applying selected cladding material.


Brick cladding is one of the best cladding options for its classic look and long life. However, it is expensive due the cost of the bricks and the cost of workmanship to install.


A pavement tiles press is a machine used to mass-produce concrete or cement tiles that commonly used for paving walkways, driveways, and outdoor and indoor spaces. It is the most cost efficient tile production machine. It typically consists of a few main components:

    • 1. Hopper or Feeder: This is where a semi-dry mixture of concrete or cement, along with aggregates like stones and sand, are loaded. The hopper feeds the mixture into the press for further processing.
    • 2. Pressing Mechanism: The pressing mechanism is responsible for compacting the semi-dry mixture into the desired shape and thickness. It applies pressure to the mixture to create uniform tiles. This mechanism may use hydraulic, mechanical, or pneumatic systems to generate the required compaction, with or without vibration.
    • 3. Mold or Die: A mold block consists of many mold cavities to define the tiles outer profile. A press block consists of set of dies well aligned with the cavities to shape the top texture of the tile. Mold cavities and dies together determines the final design, texture, and size of the pavement tiles. Note her the limitations of the shape to be in profile format with top shape made by the press dies that can be pushed out of the mold without damage. The concrete semi-dry mixture poured into the mold cavities, and the pressing mechanism applies pressure to shape and compact it into the designed profile shape, thickness and texture.
    • 4. Ejection System: Once the tiles pressed and formed, an ejection system used to release the tiles from the mold cavities. This can be manual or automated, depending on the design of the press. In high production presses, the tiles pressed directly on draw table or directly on the pallet that will eventually receive the green tiles for stacking and curing.


The entire process of the pavement tiles press involves loading the semi-dry mixture, pressing it to the desired shape and thickness into a mold cavity and dies, vibrating and compacting, and finally ejecting the formed tiles into a pallet for curing. It is an efficient and precise method for producing high quality and high quantity pavement tiles.


In this patent, the cladding brick designed to be produced in high production pavement press utilizing its capability to make mortarless thin cladding bricks with means of fastening to the substrate wall. Producing it on pavement press, will impose restrictions and limitations on the brick profile, which should be taken into consideration.


The brick 1 in FIG. 1,2,3, made according to the desired dimensions and face design with upper tongue 2 and bottom groove 3 along its length with side slot 4 and dent 5 made with die stamp of the press while the other side is flat 6 against the pallet. The tongue 2 and groove 3 has sufficient clearance 7, FIG. 5, allowing for mold wearing and for the T bracket.



FIG. 4, show how the wall will look like when built without mortar. It can be produced with brick spaces or with longitudinal chamfer or flat. The face also can have longitudinal texture or can be split face.


Mounting brackets FIG. 6 can be of any desired shape; such as Z shape 8 or L shape 9 or T shape 10. Brackets are not needed for every brick, as it will mount the cladding well if used one for every several bricks depending of the substrate wall and the type of back fill. The T shape bracket 10 will need a manual cut 14 in the back of the groove, FIG. 7, with enough clearance 7 between the interlocking bricks.


Depending on the height of the product and stability of the handling system, bricks can be produced in singles, FIG. 8a or for more stable in double, FIG. 8b,c and be split after curing. Double brick with attachment in the back c can be split on site to produce two bricks with flat face. Double brick with attachment in the face b can be split to produce two bricks with stone texture face. FIG. 9 showing the split line from the pallet side.


The mold can be of multiple cavity, 11, FIG. 10, with multiple dies 12 pressing the brick and shaping the side slot and dent, pressing against the pallet 13. Dies 12 also eject the green brick out of the mold 11 into the pallet 13 which then be taken to curing chamber.



FIG. 12 is a close-up view of the multi-cavity mold with section view to show inside separator which shows separator 15 in mold section.
