  • US20150259910A1 proposes connecting a number of building blocks to one another in a form-fitting manner via connecting elements, as a result of which a building block without residue can be obtained after the connecting elements have been removed.
  • connecting elements due to the necessary form fit, such building blocks require complicated manufacturing conditions on the one hand and complicated assembly conditions on the other hand, so that the building blocks prove to be impractical for mass applications.
  • the invention is therefore based on the object of proposing a method and a device for forming masonry which, despite simple assembly and production conditions, allows the building blocks to be reused to form strong masonry.
  • the invention solves the task in that a first layer of building blocks is laid, a textile fabric having at least one passage opening is placed on the setting surface of the first layer of building blocks, an adhesive is applied to the setting surface of the first layer of building blocks without contact in the area of the passage opening applied to the textile fabric and then a second layer of building blocks is placed on the textile fabric.
  • a small amount of adhesive is used to connect the stacked building blocks, so that if the building blocks are later released as part of the dismantling of the masonry, the building blocks can be released by applying a tensile and Shear stress can be easily separated from each other.
  • the method according to the invention is based on the finding that the connection of the building blocks is achieved not only by the adhesive itself, but also by the adhesion of the building blocks when the masonry is subjected to pressure. If, for example, the masonry is only loaded by the dead weight of the building blocks during erection, a sufficient connection is primarily achieved by the adhesive. In the event of an increased pressure load (e.g. in the event of a load from a ceiling), corresponding frictional resistances arise between the building blocks and the textile fabric, making it more difficult for the building blocks to be displaced in relation to one another.

  • the adhesive provides additional support, especially in the case of special loads, such as an earthquake or when constructing or dismantling the masonry.
  • a sufficiently large force is achieved to hold the masonry together, so that building blocks known from the prior art and which are easy to produce, such as flat bricks, can be used .
  • the assembly process proves to be simple and time-saving, since the textile fabric can be laid much faster than with an assembly process in which the entire setting surface is coated with adhesive.
  • adhesive is only applied in the passage openings.
  • the textile fabric has a compensating function to prevent or reduce stress peaks in the event of slight unevenness in the largely flat setting surfaces.

  • at least one passage opening of the textile fabric is preferably assigned to each setting surface of a building block.
  • the horizontal base and top surface of a building block preferably a planar brick, can be seen as the setting surface of the building block.
  • the seating surfaces are essentially flat, which means that the seating surfaces can deviate from a completely flat design within standardized limits.
  • the method of forming masonry with building blocks having planar setting surfaces can be described as follows. First, a first layer of building blocks is laid, forming the bottom layer. Subsequently, a textile fabric which preferably covers the setting surfaces of a plurality of building blocks arranged next to one another and has a passage opening is placed on the setting surfaces of the first layer of building blocks.
  • the adhesive is then applied to these setting surfaces in the area of the passage opening(s), so that the adhesive does not come into contact with the textile fabric.

  • the second layer of bricks forms the first layer for another layer of bricks in a subsequent masonry construction step in which further layers are stacked, so that the method does not, of course, apply to the bottom and the limited to the layer adjoining the bottom layer.
  • the passage opening preferably has a smallest diameter of 3 cm.
  • the dot of glue has a diameter of 2 cm.
  • the adhesive does not touch the textile fabric immediately after application, ie at a distance from the edge of the passage opening is, a pressure impact-related drifting apart of the adhesive in the direction of the textile fabric, which leads to the adhesion of the textile fabric to the building blocks, is largely prevented.
  • a narrow area of the textile fabric surrounding the passage opening is glued to the building block, which, however, can be easily detached from the setting surface of the building block due to the small contact area.
  • the adhesive be applied to the first layer of building blocks in such a way that it is at a distance from the edge of the passage opening after pressure has been applied by the second layer of building blocks and after curing. It has been found that this can be achieved in particular when the ratio of the smallest diameter of the applied adhesive to the smallest diameter of the passage opening is 1.7-2.3 to 2.7-3.3, preferably 2 to 3.
  • the method can be used to form a device for forming masonry with at least two building blocks which have planar setting surfaces and are arranged one above the other and between whose setting surfaces a textile fabric is arranged.
  • the textile fabric has a passage opening in which an adhesive arranged without contact with the textile fabric is provided for the material connection of the building blocks.
  • the passage opening can be, for example, a round hole, a slot, a square or the like.

  • lattices or nonwovens made of plastic or glass fibers can be used as a textile fabric.
  • the adhesive can be at a distance from the edge of the passage opening in the hardened state. In this way, a bond between the textile fabric and the building block will be prevented, so that the fabric can be easily detached from the building block. So that a sufficiently strong hold of the masonry can be guaranteed even when using particularly small amounts of adhesive, it is proposed that the textile fabric be a fleece. It has surprisingly been found that, in particular by using the fleece, for example glass fleece or carbon fleece, due to the non-directional course of its fibers, a force distribution that is uniform in all directions along the textile fabric is generated, which leads to advantageous friction conditions between the building block and the fabric and thus to leads to improved stability.

  • the textile fabric prevents the building block from being driven apart by a vertical compressive load on the building blocks transverse to the vertical direction of pressure, since the stresses induced thereby are carried away by the stiffer fabric, which is in frictional contact with the building blocks.
