Definitions
- the invention relates to a plaster base and a method for its production with the features in the preamble of the main claim.
- Such a plaster base is known from practice. It consists of an insulation board with several long straight caterpillar lines made of a foamed plastic. The caterpillars carry the grille on top and act as a spacer from the insulation board. To lay the plaster base, the insulation board is attached to the wall to be plastered using dowels or the like. The previously known plaster base is bound to the insulation board and can only be installed with this.
- Another plaster base is also known from practice, which consists of a grid and several loose star-shaped spacers with six arms.
- the spacers are part of the dowel and are only connected to the grid when the plaster base is installed. They are only ever present at the attachment points. As a result, their number is relatively small.
- the spacers are made of a hard plastic material and have narrow openwork webs, so that they dig into a relatively soft surface and lose their spacer function. This is particularly unfavorable for facade cladding, which usually have relatively soft panels.
- the spacers due to their small number, the spacers hardly have any support function for the plaster, which can slip in the spaces between them. In this context, breakthroughs in the arms also have a negative effect.
- the relatively small spacers also harbor the risk of plaster inclusions.
- the invention solves this problem with the features in the main claim.
- the plaster base according to the invention consists of a grid and a large number of individual spacers which are connected to the grid.
- the plaster base is self-supporting and does not require its own support plate. It can be installed on any wall and horizontally, vertically or at an angle. This is also particularly quick, easy and inexpensive.
- the plaster base according to the invention can have reinforcement and support functions for the plaster.
- the spacers are regularly distributed over the grille and provide even support for the grille. They are also provided in a large number, which is much larger than the number of attachment points. The distances between the spacers are relatively small. As a result, the spacers also have a supporting function for the plaster. This property is supported by the star-shaped design of the spacers with outward-pointing extensions.
- the star shape of the spacers also offers a wide support for the grid, which does not give in when the plaster is applied.
- the large number and regular arrangement of the spacers also prevent the grid from giving way in the regions between the spacers.
- the spacers in the preferred shape and size do not run the risk of plaster inclusions.
- the design of the grid and the spacers can be varied. Any type of suitable carrier material is understood as a lattice, for example also perforated plates, expanded metals or the like.
- the spacers can be modified in their shape and in the number of their extensions. The arrangement of at least three extensions is recommended for the support function. A regular design and alignment of the extensions, which preferably have the same angle to one another, is also advantageous for the support function.
- each spacer has four extensions, each offset by 90 °. It can be aligned on the grid so that the extensions coincide with the directions of the plaster base or the grid axes. In many cases, however, an oblique arrangement of the spacers is more favorable, the extensions preferably taking an angle of 45 ° to the laying directions or grid axes. In this way, the upward-facing adjacent extensions form a trough that catches and supports the plaster.
- the tub shape can also be realized with three-arm spacers.
- the plaster base is usually fastened to the substrate using dowels and screws, but can also be done using hooks, clamps, nails or other means.
- the spacers can have an essentially ring-shaped central part with a dowel hole through which the dowel and the screw or another fastening element are placed.
- the spacers can be arranged separately from one another and connected to the grid.
- the mat can be easily handled and connected to the grid.
- the nodes of the grid can be separated and removed. At these points, there are free spaces through which the plaster can distribute itself evenly, whereby it is supported by the remaining extensions. The free spaces also serve as dowel holes.
- the nodes can remain. They are then advantageously designed as thinned connecting webs between the extensions, which also allow the plaster to pass through.
- the plaster base can be produced in a continuous process in both variants and thus particularly economically.
- the spacer is preferably made of an elastic material and is made, for example, as a foamed or molded part made of polyethylene, styrofoam or polystyrene.
- Its elasticity has the advantage that the plaster base can be rolled and packed in very long lengths.
- the shape of the grille itself is usually sufficiently elastic. This property can be selected by choosing a suitable material, e.g. Glass fiber fabric, can be further improved, the grid still having sufficient stability to fulfill the reinforcement function for the plaster.
- a plaster base (1) is shown in various embodiments, each consisting of a grid (2) and a plurality of spacers (3), which are evenly distributed and connected to the grid (2).
- the connection is preferably made by gluing, but can also be done in other ways, for example molding during lattice production.
- the spacers (3) distance the grille (2) from the wall (5) and create an intermediate space into which the plaster (4) can flow.
- the plaster base (1) supports and reinforces the plaster (4).
- the height of the spacers (3) and thus the distance from the wall (5) depends on the type of plaster (4) and can be varied. For example, a higher height is required for thermal plaster than for simple plaster.
- the spacers (3) are preferably made of an elastic material and are designed, for example, as a foam part made of polyethylene or polystyrene. As a result, they are light and do not dig into the subsurface, especially soft insulation boards, when laying and applying the plaster (4). However, the elasticity is limited in order to ensure the sufficient spacing of the grille (2) from the wall (5).
- the spacers (3) are easy to manufacture, for the embodiment of FIGS. 1-3, for example in the form of a long strand, from which they are cut off in the desired thickness or height.
- the grid (2) can consist of metal or another suitable material. Also advantageous is a grating (2) in the form of a glass fiber fabric, which has favorable mechanical properties and is particularly suitable for an adhesive connection of the spacers (3).
- the spacers (3) are arranged on the grid (2) in a large number, which is significantly higher than the number of fastening points (6).
- the spacers (3) are arranged in a regular distribution. They are preferably aligned in aligned horizontal and vertical rows, but can also be arranged offset.
- the gaps (15) between the spacers (3) are preferably substantially the same size as the spacers (3), i.e. their length and width. The gaps (15) can also be smaller than the spacers (3).
- the spacers (3) have a star shape with outward-pointing extensions (7).
- four extensions (7) are arranged, which are regularly distributed starting from an essentially ring-shaped central part (9) and each enclose an angle of 90 ° between them.
- the spacer (3) can also have three or more extensions (7) or another arrangement and distribution of extensions (7).
- the shape of the middle part (9) can vary.
- the middle part (9) has a central dowel hole (10) through which a dowel and a screw or other fastening element are placed for fastening the plaster base (1) can.
- a dowel (6) is only placed in some spacers (3), the others remain empty and only support and distance the grid (2) from the wall (5).
- the plaster base (1) is usually laid on the wall (5) in horizontal or vertical paths. Due to the elasticity of the spacers (3) and the resilience of the grille (3), the plaster base (1) can be wound into rolls, as a result of which long lengths of web can be accommodated in a small space. On the other hand, the plaster base (1) can also be laid in long lengths. By connecting the spacers to the grid, laying is very quick, easy and inexpensive. The plaster base (1) is simply rolled off the wall and fastened in the desired places.
- the laying and fastening can vary depending on the requirements of the plaster.
- the plaster base (1) can be laid floating.
- thicker thermal insulation plaster it serves to reinforce the plaster (4) and is anchored to the wall (5).
- the spacers (3) are preferably arranged with their extensions (7) obliquely to the laying directions (12).
- the laying directions (12) coincide with the grid axes (11), so that the extensions (7) also extend obliquely to the grid axes (11). You make an angle of 45 ° to the grid axes (11).
- the extensions (7) are so large that they overlap and support several meshes.
- the two adjacent extensions (7) which are directed upwards on the wall (5), form a V-shaped trough (8) which catches and supports the plaster (4).
- the spacers (3) are preferably all oriented identically with their extensions (7). Due to the regular arrangement of the spacers (3) and their small distances, the viscous plaster (4) cannot slip even in the horizontal gaps (15).
- the spacers (3) have essentially full-walled extensions (7) which meet the support function. Their walls can have relatively small depressions or projections for a stronger clinging of the plaster.
- the length of the extensions (7) is preferably 4 cm or more with a width of at least 1 cm.
- the height of the extensions (7) can vary and depends on the requirements of the plaster and the desired support and reinforcement function.
- the spacers (3) can be installed on any wall without digging in.
- the support and connection surface of the extensions (7) for the grid (2) is sufficiently large.
- the outer rows of the spacers (3) are each arranged at a distance from the grid edge (13). This distance is preferably as large as the gaps (15). In this way, a protrusion (14) is created, which enables overlapping laying of adjacent plaster base sheets. This results in constant distances between the spacers (3) over all the tracks and the entire wall (5).
- the overlapping laying of the overhang (14) also has the advantage that there are no seams in the plaster (4) that would be visible from the outside.
- 4-7 show alternative forms of a plaster base (1) with a grid (2) and a plurality of spacers (3).
- the individual spacers (3) are only produced during production in a continuous manufacturing process which is explained in more detail below.
- the spacers (3) are all interconnected and form a network (16).
- Fig. 4 shows this network (16) in the left half of the drawing.
- the extensions (7) of the spacers (3) are connected to one another by the nodes (18).
- the net (16) forms a mat (17) which is wound into a roll in a long web or is already present in cut pieces.
- the net (16) has uniform, preferably rectangular or square meshes which are larger than the meshes of the grid (2).
- the network (16) with its strands forming the extensions (7) is oriented obliquely, preferably at an angle of 45 ° to the laying directions (12) of the finished plaster base (1) and the grid axes (11).
- the extensions (7) also form V-shaped troughs (8) for collecting the plaster.
- the net (16) or the mat (17) is glued to the grid (2). Adhesive spots are preferably only in the area of the extensions (7), but not at the nodes (18). The mat (17) is glued accordingly and attached to the grid (2) hung up.
- the spacers (3) or their extensions (7) are cut freely on the finished plaster base (1).
- the nodes (18) are separated from the grid (16) and removed.
- the separation can be done in any suitable manner. In the exemplary embodiment shown, the cut is made. All nodes (18) are preferably removed, but this can alternatively also be done with only a part.
- the separation creates free spaces between the extensions (7). Dowels or other fastening elements for the plaster base (1) can be attached at these points.
- the free spaces (26) correspond to the dowel holes (10) in the exemplary embodiment in FIGS. 1 to 3.
- the spacers (3) or the network (16) consist of plastic, preferably of foamed polystyrene.
- the extensions (7) have essentially the same dimensions and configurations as in the exemplary embodiment in FIGS. 1 to 3. Furthermore, the above-described projection (14) is present between the grating (2) and the spacers (3).
- Figure 5 shows the design of the network (16) or the spacers (3) in detail.
- I-shaped connecting webs (19) are arranged at the nodes (18).
- At the ends (20) of the extensions (7) each connect obliquely, preferably at an angle of 45 °.
- the connecting webs (19) have an indentation (22) in the area of the central part (21) and are aligned with their central part (21) along the production direction (23) of the plaster base (1).
- the cutting direction (24) is parallel to the production direction (23).
- the connecting webs (19) are separated by two parallel cutting lines (25) which run at a distance outside the indentation (22). In this way, all four ends (20) are cut off from the extensions (7).
- the extensions (7) also have pointed ends.
- the plaster base (1) can be produced in a continuous process.
- the net (16) or the mat (17) is first carried out under a glue station (29) which applies the adhesive to the extensions (7).
- the grid (2) is then placed over a subsequent feed device (30) and glued to the mat (17).
- the two then travel together through a cutting device (27) which extends transversely to the production line. It has a number of cutting tools, preferably knives or filaments (28). Their number and arrangement depend on the desired open spaces (26).
- the knives or filaments (28) are arranged along the production direction (23) and cut off the connecting webs (19) in the manner described above. In the absence of bonding with the grid (2), these fall down in the cutting device (27) or on the subsequent conveying path and can be collected for further use.
- the plaster base (1) is now ready and can be wound up in rolls or cut to length as required.
- the mat (17) can also be placed on the grid (2).
- the separated connecting webs (19) are then suctioned off or removed in some other way.
- FIG. 7 shows a further variant of the plaster base (1) in a detail.
- the spacers (3) are connected to one another to form a net (16) or a mat (17).
- the nodes (18) are retained and are designed as thinned connecting webs (31) between the extensions (7).
- the height of the connecting webs (31) is preferably lower than in the adjacent extensions (7).
- the plaster can step between the extensions (7) and flow over or under the connecting webs (31).
- the connecting webs (31) can also be narrower than the extensions (7).
- the connecting webs (31) can have a simple X-shape.
- the dowels or nails are then placed next to the connecting webs (31).
- the connecting webs (31) in the middle can also have an annular middle part (9) with a dowel hole (10) according to FIG. 2.
- Combinations are also possible. 7 shows different variants of the web design in a top view and in a small broken side view of a node.
- the mat (17) can be designed as a molded part made of plastic. It is glued to the grid (2), which is optionally placed on the front or back of the mat (17). This is the simplest and quickest form of production since there are no additional processing operations.
- the grid (2) and mat (17) can be connected continuously depending on the length of the web.
