The innovative Porotherm bricks of the new Robot Ready series.

The masonry robot currently only works with the innovative Porotherm bricks of the new Robot Ready series. Compared to standard Porotherm bricks, these bricks have additional special grooves at the front, used by the robots to hold and lay the brick. In terms of thermal insulation properties, load-bearing capacity, strength, acoustic parameters, and fire resistance, the robotic brick does not differ from the conventional brick. The first processable type of brick is Porotherm 30 RR Profi Dryfix P10.

To meet the demands of the respective markets, additional types of Robot Ready bricks will be introduced gradually.

Porotherm 30 Robot Ready Profi Dryfix

Porotherm 30 RR Profi Dryfix grinded blocks are intended for plastered single-layer load-bearing internal and external masonry with a thickness of 300 mm for masonry in structural work, and specifically designed for use in robotic masonry. They can also be used for the internal load-bearing part of multi-layer masonry or in combination with thermal insulation and, if necessary, with other brick materials forming the external protective part of bonded masonry.

Porotherm 19 Robot Ready AKU Profi Dryfix

Porotherm 19 RR AKU Profi Dryfix grinded blocks are intended for single-layer load-bearing masonry with a thickness of 190 mm for robotic masonry (they can be used in the construction of hotels,hostels, offices, etc.). They can also be used for the internal load-bearing part of the layered masonry in combination with a thermal insulator and possiblywith other brick materials. Facing bricks act as the outer protective layer of the masonry.

Bonding material

With regard to the combination of brick type and adhesive foam, the corresponding characteristic compressive strength of the brickwork must be taken into account. The introduction of robotic application of thin-bed mortar is expected to take place in 2025.

WLTR’s Fields of Operation.

Requirements for the use of robotic bricklaying.

It is not required for projects to be created using the BIM method. However, it is advantageous to create projects using this method because the robot software is already prepared for this interface, and a BIM project can be used for further development of the robot software.

The masonry robot is most efficient when building long, straight walls with few openings. This includes, for example, internal and external load-bearing walls, as well as infill or partition structures of:

Commercial & industrial buildings

Administrative buildings

Public utility buildings

(hospitals, schools, shopping centers, sports arenas, etc.)

Standardized residential & apartment buildings

Usage in skeletal structures (monolithic + prefabricated)

Maximum Height

The masonry robot builds up to a height of 3.25 m from the base of the wall. The maximum height of the wall relative to the ceiling is 10 cm below the ceiling structure. It is necessary to consider the possible deflection of the skeletal structure. The gap between the wall and the horizontal structure should be filled (e.g., with mineral wool boards) according to project requirements regarding acoustics, airtightness, fire resistance, etc.

Supporting Structure

The brickwork is connected to the vertical structures (columns) using steel wall clips and a project-defined option with mortar, mineral wool, or asphalt strips.

Clear Space

There must be a clear space of at least 5 m parallel to the built structure for WLTR to work and handle the material. Therefore, it is necessary to consider, acoustic partition walls extending to the outer face of the enclosure walls, penetrating structures through the foundation/ceiling structure, already finished structures, etc.

Consider the Load

During brickwork on floors, the load of the masonry robot and the pallets of bricks must be considered. Conversely, the imposed load of the structure is not to be considered.

Axial Spacing

The minimum spacing between columns must be at least 4 m for the masonry robot.

Construction Methods

In the case of using a combination of steel and brickwork construction and robotic bricklaying, the above information applies. Alternatively, the project and its specifications can be discussed with GreenBuild engineers.

Usage in brickwork structures

125mm Design

When designing, it is advisable to use a 125 mm length module. The masonry robot lays the bricks based on the module specification (not adjacent to each other). This allows WLTR to utilize additional half bricks and increases the efficiency of the entire process (eliminating brick cutting).

Structural Analysis

The structural analysis must consider the characteristic compressive strength of the brickwork for the Dryfix variant. In the case of a material change during the design phase, it is possible to collaborate with Wienerberger structural engineers.
