Definitions

  • the invention relates to a method for joining bricks, the plane-parallel storage or setting surfaces and at least one open to the storage or setting surfaces cavity, for the production of a building block, in particular masonry.
  • the invention relates to a set for creating a modular composite, in particular masonry, of bricks, which have plane-parallel storage or setting surfaces and at least one open to the storage or setting surfaces cavity.
  • the invention also relates to a building block, in particular masonry, comprising a plurality of bricks, wherein mutually facing brick surfaces of superposed bricks are connected to each other using said set.
  • the Austrian patent AT 414333 B describes a method for connecting planar building blocks to form a modular composite, such as bricks for building a wall using a connecting material, wherein an expandable plastic material, in particular PUR foam is used as a connecting material.
  • the expandable plastic material is applied either selectively, along at least one line or surface.
  • Expandable plastic material and in particular polyurethane foam adhesive, is associated with significantly higher costs compared to the use of a conventional mortar for joining bricks, so that in principle one endeavors to keep the amount of the polyurethane foam adhesive as low as possible.
  • the layer thickness is as low as possible.
  • the layer thickness can not be reduced arbitrarily, since the connecting surfaces of the bricks are not completely flat in the rule. It is therefore necessary depending on the surface texture of the bricks a certain minimum layer thickness to compensate for surface irregularities.
  • the bricks are usually designed as hollow bricks, ie with hollow chambers, so that usually already 30 to 60% of the total surface of the brick can not be used for the adhesive bond anyway.
  • the defined by the cavities formed in the brick cavities from manufacturer to manufacturer is very different, whereby a standardized application of the adhesive in a given line or dot pattern would cause a significant proportion of the applied adhesive only in or on the cavities of the brick.
  • a subset of the adhesive which was applied to the arranged between the cavities webs pushed out laterally during subsequent pressing of the upper brick is and enters the cavities and thus can not be used for the bonding process.
  • polyurethane adhesive is usually made of storage containers in which the adhesive is held under pressure and from which the adhesive can escape upon actuation of the can valve.
  • the adhesive is customary to install the usually designed as a tilt valve can valve as a pipe or the like. Formed adapter or to connect the can with a gun applicator.
  • the invention aims to simplify the application of an adhesive to setting or storage surfaces of a brick and to keep the adhesive consumption low, without the stability of the adhesive bond is impaired, in particular the penetration of adhesive into the cavities of the brick should be avoided ,
  • the at least one cavity bridging net-like sheet Effectively prevents the side of the adhesive surfaces of each superimposed bricks escaping adhesive gets into the cavities of the brick.
  • the laterally emerging adhesive is rather collected on the surface of the net-like sheet and distributed on both sides of the adhesive surface, so that selective accumulation of adhesive can be avoided.
  • the distribution of the adhesive may even extend so far that the regions of the reticulated fabric which are located above the at least one cavity are completely covered with adhesive, so that a total of one continuous adhesive layer between two superimposed bricks is formed, creating a so-called. Covering of the cavities is formed.
  • the cavities cover prevents the passage of air between two superimposed bricks, which prevents the circulation of air in the cavities (chimney effect) and improves the insulating properties of the brickwork.
  • a structure of a plurality of spaced apart and intersecting threads or tapes is understood.
  • the individual threads or ribbons may in this case be arranged in the manner of a woven fabric, or the individual threads or ribbons may also be fused or glued together.
  • the invention provides that the net-like sheet consists of polypropylene or polyethylene or is formed by a paper or felt-like mesh.
  • the net-like fabric is already provided with an adhesive when placed on the first layer of bricks or is placed on an adhesive layer. Rather, the net-like fabric can be applied directly to the first layer of bricks, wherein the adhesive bond between the superimposed bricks is produced solely on the basis of the adhesive applied in step c).
  • the adhesive is pressed into the spaces between the threads or ribbons of the net-like structure, so that the adhesive layer has a direct connection between the bricks of the first and the bricks of the second Situation produces.
  • the net-like sheet is thus embedded in the underside of the adhesive layer and forms a discontinuity within the adhesive layer.
  • the diameter of the filaments or ribbons of the reticulated fabric is less than 200 .mu.m, preferably less than 50 .mu.m.
  • the threads of the reticulated fabric have a round cross-section.
  • the filaments of the net-like sheet are ideally in contact only with formation of a line contact with the sheet or setting surface of the first layer of bricks, whereby the caused by the net-like sheet Reduction of the adhesive surface can be further optimized.
  • a further improvement provides that the threads of the reticulated fabric are made of filaments, whereby the permeability of the threads for the adhesive is increased, so that the condition is created that the adhesive also on the first layer of the brick facing side of the net-like Textile penetrates.
  • the ratio of the mesh size of the net-like sheet to the viscosity of the adhesive is chosen so that substantially no adhesive passes into the at least one cavity.
  • the mesh size of the reticulated fabric is in this context preferably 100 ⁇ m - 2mm.
  • the dynamic viscosity can be in a relatively wide range between 0.5 and 10 Pa ⁇ s.
  • the choice is made such that, for an adhesive having a viscosity at the level of the upper limit of the stated range, a larger mesh size, and in particular a mesh size of 2 mm, is preferred than with a viscosity of the adhesive at the level of the lower limit of the specified area.
  • a larger mesh size and in particular a mesh size of 2 mm
  • the higher the viscosity of the adhesive the larger the mesh size can be, assuming that the mesh size is approximately linearly dependent on the viscosity of the adhesive.
  • the adhesive is preferably applied in strip form to the reticulated fabric.
  • the adhesive is applied in at least two parallel spaced strips. The strips are preferably applied so that they come to rest, at least for the most part, over the webs formed between the cavities of the brick.
  • the adhesive consumption can be significantly minimized.
  • the adhesive can also be applied over the entire surface of the net-like fabric and / or distributed, which, however, results in a significantly higher adhesive consumption.
  • the length of the sheet at least a multiple of the length of the individual bricks corresponds.
  • the network can be applied to a multiplicity of juxtaposed bricks, in particular bricks, for example over a length of 2 to 5 m.
  • the net-like fabric is cut to such an extent that its width substantially corresponds to the width of the plane-parallel setting or storage surface, so that only a single net must be applied over a corresponding length.
  • the network is used over the entire length of the layer of bricks. There should thus remain no gaps between two longitudinally adjoining networks.
  • a particularly stable adhesive bond can be achieved if the adhesive consists of a plastic material which can be applied in the flowable state and then cured, in particular polyurethane adhesive.
  • Polyurethane adhesives are available as one- or two-component adhesives which can be cured by polycondensation or polyaddition. One-component PUR adhesives cure with the addition of atmospheric moisture.
  • PUR adhesives are known to include diphenylmethane diisocyanate, toluene diisocyanate, hexamethylene diisocyanate or the like. Further, isomers, homologs or the like are contained.
  • the advantages of the PUR adhesive consist not only in its ease of processing, but also in its excellent adhesion to various material surfaces. Another advantage is that the adhesive material in the application to a surface of a brick in the pores or recesses (meaning not the production specific hollow chambers) of the brick, in particular hollow brick, penetrate or at least partially cover, whereby the heat conduction can be reduced ,
  • bricks are, for example, bricks, in particular hollow bricks, lightweight concrete bricks or the like.
  • the invention relates to a set for creating a modular composite of the type mentioned above, which can be attached between the mutually facing storage and setting surfaces adhesive from a pourable in the flowable state and then curing plastic material, in particular polyurethane adhesive, for mutual fixing of the individual bricks and a preferably free of adhesive net-like fabric with a certain mesh size, which is the at least one cavity covering laying on a layer of bricks, comprises.
  • plastic material in particular polyurethane adhesive
  • the set preferably consists of these two components and no further components are required.
  • the ratio of the mesh size of the reticulated fabric to the viscosity of the adhesive is preferably again selected such that substantially no adhesive passes through the reticulated fabric into the at least one cavity.
  • the adhesive is preferably provided in storage containers, in particular cans, in which the adhesive is held under pressure.
  • an adhesive distribution device which can be brought into contact with the can valve, by means of which the adhesive can be applied simultaneously in at least two, preferably a plurality of, in particular parallel strips.
  • the net-like sheet is preferably made of a material which is not rotting in the long term, which is non-hygroscopic and which is further resistant to insect feeding.
  • the stated material properties are advantageous, in particular, for the long-term stability of the adhesive bond, since, for example, rotting or erosion by insects would lead to a corresponding reticulated cavity within the adhesive layer or on the underside of the adhesive layer.
  • a modular composite, in particular masonry proposed comprising a plurality of bricks, the plane-parallel storage or setting surfaces and at least one open to the storage or setting surfaces cavity, facing each other brick surfaces of superimposed bricks under Use of a set according to the invention are connected to each other, wherein the net-like fabric covering the cavity between the upper storage or setting surface of a brick and the adhesive disposed or embedded in the underside of the adhesive.
  • FIG. 1 a masonry consisting of a large number of hollow bricks
  • Fig. 2 a top view of a first layer of hollow bricks
  • Fig. 3 a view according to Fig. 2 with on-line network

Between the individual layers of the hollow brick 1, an adhesive bond 4 is in each case provided using a reticulated sheet and an adhesive.
  • the hollow orifice brick has a plurality of cavities 5, between which webs 6 are formed.
  • the Asked by the webs 6 available surface can basically as an adhesive surface be used for the gluing process. Adhesive, which enters the cavities 5, however, can not be used for the adhesive bond.
  • the setting or laying surface of the hollow brick 1 is prepared by placing a network 7 for the gluing process.
  • the mesh 7 extends over the cavities 5 of the hollow brick 1 and thus covers substantially the entire surface of the hollow brick.
