Definitions

  • the invention relates to a hollow block component, with a component body which encloses at least one recess on its upper side and has at least one cam which can be inserted into the recess of a similar component arranged underneath on its underside.
  • Such components usually consist of concrete, lightweight concrete, clay or the like and are used for the binder-free construction of buildings.
  • the components are offset so that each of the cams of the components of a row surround the recesses of the components of an adjacent row, so that a stable, form-fitting connection is created.
  • the designation top and bottom only serves the nomenclature, the components can of course Lich used in both arrangements, however, the arrangement of the cams on the underside is usually preferred. so that the building has a smooth top.
  • the component body can be made more or less solid and in any case has on the side opposite the cams on the circumferentially closed recesses which are dimensioned at least so that they accommodate the cams.
  • the component element is usually designed as a honing block, which may be ribbed in accordance with the structural requirements.
  • the component body consists of a frame element, in the interior of which one or more hollow cylinders are arranged as a stiffening core.
  • Cams and recesses are formed by the fact that the hollow cylinders are offset in height with respect to the frame element so that they protrude from the frame elements on the top and a space remains free on the underside within the frame element.
  • These known hollow block components have proven their worth in the construction of garden walls, patio supports, fencing, etc. However, they can only be moved in a seamless connection, and in particular a lateral offset of rows lying one above the other cannot be carried out, so that only vertical walls can be erected.
  • the invention has for its object to provide a hollow block component of the type described above, with the embankment fastenings etc. can be erected, which are characterized by a stable, form-fitting structure with a high proportion of voids and gaps. In particular, the possibility of adapting to different applications in a further area is sought.
  • each recess is assigned a cam set of at least two cams and that the distance between adjacent cams corresponds at least to the wall width of the recess.
  • four cams are assigned to each recess; under certain circumstances, an even larger number of cams per recess can also be expedient.
  • the cams on the corners be with the limits of the rectangular plan of the component parallel to the rectangle (or square) arranged parallel sides, so that an overall largely regular structure of a component according to the invention results.
  • the arrangement of the cams according to the invention has the result that there are, as it were, incisions running parallel or perpendicular to the limits of the component, into which the walls of the recess of a component arranged below can engage, so that conversely one or more of the cams in the recess are fixed, while the other cams of the cam set in question lie outside the recess.
  • the result is a displacement of the components in the longitudinal or transverse direction, whereby there is a clear positive connection. So that an extensive, continuous bond is created, the components naturally each have several, as a rule two recesses and two cam sets. Depending on their design and mutual spacing, there is the possibility of placing the components with more or less wide passages on the gap.
  • the possibility of arranging the components laterally offset from one another creates the possibility of adapting to different slope inclinations, the high degree of static stability always being ensured by the interlocking between adjacent components; is.
  • the components according to the invention are generally not made solid but with more or less pronounced openings, which at the same time form the recesses for receiving the cams.
  • various embodiments are possible for this.
  • the longitudinal direction of the component is defined as the direction in which the chambers are arranged next to one another.
  • the invention provides in a particularly preferred embodiment that the cams of each set of cams are arranged on the transverse or chamber partition walls delimiting one of the chambers.
  • the initially existing problem that the cams sitting on the walls delimiting a chamber obviously cannot be inserted into this chamber is solved by the arrangement of the cams in the form of cam sets and the mutually offset arrangement of the components.
  • the width of the cams preferably corresponds to the width of the walls.
  • the cams themselves can largely be of any design, a design with a circular or square layout having proven particularly useful. It is advisable to have the cams taper conically or pyramid-shaped towards their free ends. This makes it easier to demold without flaking, and the components can be joined together to form a bond in a particularly simple manner.
  • the cams sit at a greater or lesser distance from the longitudinal walls on the transverse or chamber partitions, and preferably in rows parallel to the longitudinal extension of the component.
  • the dimensions of the chambers and walls are important to ensure that there are optimal possibilities when producing a composite from the components according to the invention.
  • the inside width of the chambers measured in the longitudinal direction of the component corresponds to at least twice the width of the transverse or chamber partition walls. It is assumed that the width of the cams corresponds essentially to the width of the respective wall, otherwise the clear width of the chambers can also be correspondingly smaller. This also applies accordingly to the following design recommendations. In any case, it is achieved with this design that a gapless assembly can also be established in the longitudinal direction.
  • the inside width of the chambers measured in the transverse direction of the component is at least twice the width of the transverse or chamber dividing walls greater than the inside width of the chambers measured in the longitudinal direction. This creates the important possibility of joining the components to one another in a direction perpendicular to one another.
  • a particularly advantageous embodiment of the invention is characterized by at least three chambers, namely two side chambers and at least one middle chamber arranged between the side chambers.
  • the measured in the longitudinal direction of the component Clear width of the middle chamber at least, preferably even more or less exactly twice the width of the transverse or chamber dividing walls greater than the clear width of the side chambers measured in the longitudinal direction.
  • this dimensioning ratio is more or less exactly adhered to
  • a structure is obtained in which, measured in the longitudinal direction in each case, the clear width of the central chamber corresponds to the width of the side chambers measured over the walls.
  • the inside width of the central chamber thus corresponds essentially to one third of the total length of the component.
  • a length-to-width ratio of 2: 1 is recommended for the layout of the entire component.
  • the invention provides special corner elements which are characterized in that the cams arranged on one of the transverse walls are at a distance of one wall width from the free outer side of the transverse wall and from the free outer sides of the adjacent ones Longitudinal walls each have a distance corresponding to twice a wall width.
  • the length of these corner elements preferably corresponds to half of a normal element in the composite, for example half the length of the three-chamber element explained above. It has also proven to be advantageous to design these corner elements as a single-chamber element, ie without inner chamber partition walls.
  • FIG. 1 shows a top view of a hollow block component, specifically on the underside. This is not important, however, because the components according to the invention can also be used in an arrangement which is reversed with respect to the top and bottom.
  • the component shown made of concrete, consists essentially of a component body 1, on the underside of which projecting cams 2 are formed, which are highlighted in Figure 1 by hatching.
  • the component body 1 has a rectangular plan and is made up of two longitudinal walls 3, which are connected by perpendicular, outer transverse walls 4 and internal chamber partition walls 5. These walls enclose the building element, which penetrates the component and is open at the top and bottom, namely an outer side chamber 6 and a middle chamber 7 located between them. It is therefore a three-chamber element.
  • the chambers 6, 7 thus form recesses into which the cams can enclose a similar component arranged underneath.
  • each of the chambers 6, 7 is assigned a set of cams of a total of four cams 2.
  • the cams 2 are arranged on the transverse or chamber partition walls 4, 5 delimiting the chambers 6, 7.
  • the distances (which will be dealt with in detail below) between adjacent cams 2 are dimensioned such that they correspond at least to the width of the walls 3, 4, 5.
  • the cams 2 have a square outline, the width of the cams 2 corresponding to the width d of the transverse or chamber dividing walls 4, 5 in the area of the cams 2.
  • the cams 2 taper slightly pyramid-shaped towards their free end, so that they can be easily removed during manufacture and without flaking.
  • the walls 3, 4, have cutouts 8 which bring about a tapering of the walls in order to save weight.
  • Figure 1 shows that the cams 2 are each arranged at the corners of a rectangle, the sides of which are parallel to the Grundrißbe boundaries of the component body 1 extend.
  • the cams 2 are recognizably arranged in rows of cams parallel to the longitudinal extent of the component, which in the illustrated embodiment each have the same distances from the respectively adjacent longitudinal wall 3.
  • the figures do not show the possibility that these distances from the adjacent longitudinal walls 3 can also be different.
  • the clear width a of the side chambers 6 measured in the longitudinal direction of the component is approximately the same twice the width d of the walls 3, 4, 5, while the measured inside width c of the middle chamber is twice the width d of the walls 3, 4, 5 than the inside width a of the side chambers 6
  • Clearance c of the central chamber is essentially one third of the total length of the component.
  • the inside width b of the chambers 6, 7 measured in the transverse direction of the component is correspondingly larger by twice the width d of the walls 3, 4, 5 than the inside width a of the side chambers 6 measured in the longitudinal direction.
  • FIG. 3 shows another embodiment that is used specifically as a corner element and offers the possibility of using corners flush exterior surfaces.
  • the corner element 9 shown in FIG. 3 is designed as a single-chamber element with two parallel longitudinal walls 3 and two transverse walls 4 perpendicular thereto.
  • the cams in FIGS. 1, 2 are arranged accordingly.
  • the outside of a corner forming transverse wall 10 which is twice the width of the other transverse wall, the cams 2 are arranged so that they have a distance from a wall width b relative to the free outside of this transverse wall 10.
  • the cams 2 are arranged here so that there is a distance corresponding to twice a wall width b relative to the Indeedensei th of the adjacent longitudinal walls 3 j.
  • the floor plan width of the corner element 9 corresponds to the width of the three-chamber element according to FIGS. 1, 2, while the length of the corner element only corresponds to half the length of the three-chamber element.
  • 3 shows that the cams 2 can also be designed with a circular cross section, the cam diameter corresponding to the wall width d.
  • FIGs 4, 5 and 6 show different options for the establishment of networks with the components described. Two component layers are shown, the lower one being drawn out and the upper one shown in dashed lines.
  • Figure 4 shows a closed, gapless composite.
  • the upper layer is offset from the lower, so that the resulting composite is inclined relative to the vertical, for example, according to the inclination of an embankment to be fastened.
  • a component 11 of the upper layer is arranged perpendicular to the other components and is used for anchoring in relation to the slope (not shown). M an recognizes without further explanation how the cams 2 each enclose in the chambers 6, 7 and thereby the walls 3, 4 and 5 in a form-fitting manner lock in.
  • FIG. 5 accordingly shows a flat composite in which the components are set to a gap.
  • FIG. 6 shows the execution of a corner. It can be seen how, due to the special design of the corner elements 9, the outer surfaces of the structural elements lie flush with one another.
