Description

Broom friction The invention relates to a building board set.

Building board sets usually consist of similar or identical building boards that are to be connected to form load-bearing layers. These connections are usually made by means of folds. The disadvantage of this is that the edges of the folded boards cannot be sufficiently fixed to one another in terms of height, since the respective fold only protrudes over the actual board edge on one side and can only fix the symmetrical fold of the adjacent board edge against the height offset in one direction, but not in two directions. These fold connections must therefore be additionally nailed, glued or provided with another load-bearing layer that spans the folds to prevent the boards from becoming inadmissible.

Also known are so-called tongue and groove connections. Some of the edges of the building boards are provided with grooves into which the tongues or bungs of the corresponding opposite board edges engage, so that a height offset of the board edges is excluded. The disadvantage of these connections is that the thickness of both the tongue and the tongue is only about a third of the board thickness and is therefore prone to breakage, and that the grooves represent an undercut in the board body, which can be produced using the extrusion process or by milling, but not using the stamping process. In the extrusion process, the groove can also only be made at the

The edges lying sideways in the strand direction are usually produced, while the edges lying transversely to the strand direction must be bluntly cut and butt-jointed , unless a high additional effort for processing in the subsequent operation is accepted.

In the case of so-called tongue and groove panels, the edges of the panels are opposite each other and are connected to one another by an additional tongue and groove. This brings with it the disadvantages described above when producing the grooves, as well as disadvantages due to the complicated installation.

The German utility model No. 76 11 113 has made known a set of building panels whose step fold protrudes on two adjacent edges and recedes on the other two opposite edges, where it is equipped with a interlocking system consisting of teeth and gaps that prevents the panel from shifting longitudinally in one direction. However, this does not prevent the height offset in one direction.

Furthermore, a set of building panels has become known through German utility model No. 76 18 595, the panels of which have straight edges in the lower third of the panel thickness, are provided with grooves in the middle third of the panel thickness that are connected to one another by spring tongues, and are provided with toothed strips made of teeth and gaps in the upper third of the panel thickness that mutually adjust the panels in terms of height and length offset. The disadvantage of this design is that these panels cannot be turned in any way because their surface is designed differently to their bottom surface.

In addition, the grooves cannot be produced using every technology. Furthermore, gaps are created at the intersection points of the toothed strips, i.e. at the four-plate joint, because the arrangement of the teeth and gaps is not coordinated according to any corresponding system. In addition, the last of four abutting plates can only be mounted if the toothed strip is subsequently installed, because the teeth and the gaps are bevelled less than 45° . In addition, only plates of exactly the same size fit together. I

The invention is therefore based on the object of describing a set of building panels whose panels enable mutual height and length adjustment without the use of grooves, i.e. without shaped undercuts, can be joined together in one piece and in the same plane without gaps, whose size can be different in the same set of panels and whose top and bottom surfaces are identical for each panel.

The solution to the problem is achieved according to the characterizing features of claim 1. The advantage of this ■ inventive solution is that without using I

an undercut shape, i.e. without a groove, a mutual ; height fixation of the adjacent panels is possible. |

In the preferred embodiment according to claim 2, the height, length and depth of the teeth are adapted with play to the respective height, length and depth of the associated gaps. This has the advantage that when the plate edges are joined together, a practically gapless tooth line and thus a closed surface is created.

The embodiment according to claim 3 has the advantage that the height of the teeth of the lower and upper rows is approximately equal

large and is approximately half the thickness of the plate. The advantage is the optimal strength of the plate connection in both directions across the plate plane, since no tooth is lower than the overlapping tooth.

The embodiment according to claim 4 with equal tooth and gap lengths has the advantage that the tooth and gap pitch of the upper row of teeth corresponds to the tooth and gap pitch of the lower row of teeth and thus uniform tooth engagement is ensured when turning a plate (lower surface upwards).

According to claim 5, the teeth or the gaps of the upper and lower toothed strips overlap in their length, whereby the appearance of the toothing line can be modified in the assembled state.

In the panels according to claim 6, the teeth and gaps on opposite sides are exactly opposite each other without longitudinal displacement. The advantage is that the panel set consists of identical panels. If the teeth and gaps on opposite panel edges are aligned in the same direction, i.e. parallel, the direction of the panels can be maintained during installation so that their surface shape is oriented in the same direction. If, on the other hand, the teeth and gaps are arranged in opposite directions, the direction of the panels must be partially changed or some of the panels turned during installation. The advantage of this design, however, is that panel shapes are possible that are symmetrical not only across their diagonals, but also across their center line, and are therefore more visually appealing.

The panels according to claim 7 have no symmetry and therefore have the advantage that very lively patterns can be laid

can.

In the building panels according to claim 8, a continuous straight edge is formed in the middle part of the panel height along the imaginary axes. This design has the advantage that the pressing burr guide is easier, since the direct transition from the tooth to the gap is eliminated.

In the particularly advantageous embodiment according to claim 9, the upper surfaces of the lower teeth and the lower surfaces of the upper teeth are tapered. The advantage of this shape is that manufacturing tolerances can be compensated, a sufficient gap is available for the adhesive required to connect the plates, and the adhesive is placed under high pressure by the wedge effect when the plate is pushed together.

Another particularly advantageous embodiment according to claim 10 consists in the teeth of the plates tapering towards the tooth head, namely in the case of rectangular plates by at least 45° on both sides. The particular advantage is that the last of the four plates can also be inserted as an undivided plate in the same plane at 45° into the recessed corner of the other three plates.

The simplest embodiments according to claim 11 in the form of triangles, quadrilaterals, preferably squares and hexagons in regular axially symmetrical shapes have the advantage that the panels are universally applicable and easy to lay.

A further embodiment of the invention is described in claim 12. In this form, only whole teeth or whole gaps are arranged at the plate edges.

the lengths of whole teeth and gaps at the intersection with ■ the imaginary axis of the plate edges. The advantage of this

The advantage of the arrangement is that the teeth arranged in the corner area of the panels only result in external corners of =/ 90°, while if the /. panel edges are not divided into whole numbers, sharp teeth with 45" tips would also occur with an increased risk of breakage. In addition, if whole teeth and whole gaps are arranged in the area of the joint cross (four-panel corner), no gaps that extend through the ha. ¹ .Ve or entire panel thickness occur.

In the embodiment according to claim 13, the teeth and gaps at diagonally opposite corners are arranged symmetrically in relation to the bisector. The advantage of this panel shape is that when using whole teeth and gaps, the laying direction of the individual panels in the bond can always be the same (single-diagonal symmetry).

In the embodiment according to claim 14, however, the teeth and gaps at all corners are arranged symmetrically in relation to the respective bisectors. The advantage is that each panel with full teeth and gaps has at least two preferred laying directions that can be used optionally (two-diagonal symmetry).

In a further particularly advantageous embodiment of the building board set according to the invention according to claim 15, the teeth and gaps are arranged symmetrically to the center of the boards. The particular advantage is that boards which have an even number of teeth and gaps per board edge have four preferred laying directions, ie their direction during laying has no influence on the fit.

The embodiment according to claim 16 with an even number of teeth and gaps per plate edge has the advantage that the top and bottom of the plate always have identical shapes or congruent shapes.

In contrast, the embodiment according to claim 17 with odd-numbered sums of teeth and gaps per plate edge has the advantage that it can also be used to produce flat feet that not only have diagonal symmetry but also centerline symmetry, which can be desirable for optical reasons.

The embodiment according to claim 18 is advantageously used in rectangular plates when, due to the required aspect ratio, even or odd sums of teeth and gaps of the respective edges cannot be realized on all four edges.

In a particularly advantageous embodiment according to claim 19 of the building board set according to the invention, the toothing lines in the area of the four-board corner continue in an undisturbed, regular shape. The advantage of this embodiment is that boards of this shape can also be laid in a bond if only their direction is maintained. Boards of different sizes can also be laid together if the shape and direction of all four corners correspond to the respective original shape. Further advantages are offered by the embodiments of such boards in which the toothing line crosses the axis of the board edges, since these are particularly regular shapes with special symmetries, the advantages of which have already been described above.

The invention is described below with reference to

arranged on the upper and lower panel edges 3,4 and project forwards and backwards over the imaginary axes 5,6 of the panel edges so that they can alternately engage in the gaps assigned to the upper and lower panel edges. For the sake of simplicity, the teeth 1,2 and the gaps 7,8 are shown here in the same view. Furthermore, it can be seen from Fig. 1 that the teeth 1 and gaps 32 arranged on opposite edges of the same building panel 30 are exactly opposite each other and project forwards and backwards in the same direction 33.

In the section in Fig. 2 it can be seen that tooth 1 is arranged on the upper plate edge 3 and tooth 2 on the lower plate edge 4 and engage in the gaps 7 and 8 respectively as soon as the two plates are pushed together far enough that the two axes 6 of the plate edges coincide. It can also be seen from the section that the heights 9 of the teeth 1, 2 and the heights 13 of the gaps 7, 8 arranged below and above each correspond to approximately half the plate thickness 17. It can also be seen from the section that the upper surfaces 61 of the lower teeth 2 and the upper surfaces 63 of the upper teeth 1 are tapered.
