A lining board arrangement10of Figures IA-C comprises a lining board100for being mounted to a wall of a building, whereby the facade of the building may be formed by mounting several lining boards100of Figures IA-C on the building wall side by side in both the horizontal and vertical direction of the building wall. The lining board100comprises a back-plate120and lining tiles110arranged to the back-plate120. The lining board arrangement10further comprises an angle plate200for being mounted to the lining board100. The lining board arrangement10is intended to be located near the wall sections of the building being at an angle relative to each other, such as near the window recesses of the building or the corners of the building, such that the angle plate200is located on both sections of the wall section being at an angle relative to each other. The lining tiles110are mounted to the back-plate120and/or the angle plate200by an adhesive mass130.

The lining tile110ofFIGS.1A-Chas a facade surface112which forms part of a facade side100F of the lining board100visible to the outside. In the examples of the figures, the lining tiles110are of rectangular shape, wherein the lining tile110has a specific length and a specific height. The length of the lining tile110may be e.g. 50-400 mm, preferably e.g. 285 mm, and its height may be e.g. 50-400 mm, preferably e.g. 85 mm. However, the size and appearance of the lining tiles110may vary in many different ways. The lining tile110may be e.g. a brick tile, a burned brick tile, a cut brick tile, a lining stone tile, a plastic tile, or a clinker tile.

Furthermore, the lining tile110of the lining board100has a back surface114which is located on the opposite side from the facade surface112of the lining board110. The back surface114of the lining board110is arranged to be positioned against a front surface120F of the back-plate120or near the front surface120F of the back-plate120, wherein the back-plate120will be later described in more detail.

Furthermore, the lining tile110of the lining board100has side faces116′-116″″ between the facade surface112and the back surface114. The lining tile110has a determined thickness, which may be e.g. 10-45 mm, preferably about 20 mm. The lining tiles110are fixed from their side faces110′-110′″ to an adhesive mass130and, via the adhesive mass130, to the back-plate120.

The back-plate120of the lining board100of the lining board arrangement10ofFIGS.1A-Cmay be e.g. a steel plate. The back-plate120has a front surface120F directed in the direction of the facade side100F of the lining board100and, on the opposite side, a back surface120B directed at the building wall. The back-plate120is of substantially rectangular shape, and it has a first side face120′, a second side face120″, a third side face120′″, and a fourth side face120′″ between the facade side100F of the lining board100and the back side100B of the lining board100, or in other words, a first side face120′, a second side face120″, a third side face120′″, and a fourth side face120′″ between the front surface120F and the back surface120B of the back-plate120. In the lining board120, the first side face120′ and the second side face120″ are additionally side faces oriented substantially in opposite directions relative to each other, i.e. side faces oriented away from each other, as are the third side face120′″ and the fourth side face120′″ side faces oriented substantially in opposite directions relative to each other, i.e. side faces oriented away from each other. In the back-plate120, the first side face120′ and the second side face120″ form the end surfaces or end edges of the back-plate, the third side face120′″ forms the upward directed upper surface or upper edge of the back-plate120, and the fourth side face120″ forms the downward directed lower surface or lower edge of the back-plate120.

Furthermore, the back-plate120includes grippers122, which are protrusions pointing in the direction of the facade side100F of the lining board100, or in other words, protrusions pointing in the direction shown by the front surface120F of the back-plate120. The grippers122are located in the back-plate120in an arranged manner such that the side faces110′-110′″ of the lining tiles110for being mounted to the back-plate are positioned near the grippers122. Said grippers122may be separately mounted to the back-plate120, but more preferably said grippers122are fixed portions of the back-plates120and formed of the back-plate120, for example, by punching said portion with the exception of one edge off the back-plate120and by bending it in the shape of a protrusion of the desired shape. The gripper122is  configured, in a manner to be described later in more detail, to the adhesive mass130, whereby the lining tiles110are fixed via the grippers122and the adhesive mass130to the back-plate120.

Furthermore, the back-plate120includes hangers126, from which, the lining board100is configured to be mounted for supporting hanging rails mounted to the building wall. The hangers126are protrusions oriented in the direction of the back side100B of the lining board100or i.e. oriented away from the back surface114of the lining tile110, or in other words, protrusions directed into a direction determined by the back surface120B of the back-plate120. Said hangers126may be separately fixed to the back-plate120, but more preferably said hangers126are fixed portions of the back-plates120and formed of the back-plate120, for example, by punching said portion with the exception of one edge off the back-plate120and by bending it in the shape of a protrusion of the desired shape. The hanger126formed of the back-plate120may comprise e.g. a protrusion first extending vertically away from the back surface120B of the back-plate120, from which, the protrusion continues as folded downward partially toward the lower edge120′″ of the back-plate, from which, the protrusion further extends still folded downward parallel with the back-plate120towards the lower edge120″ of the back-plate.

Furthermore, the back-plate120includes first positioners128which are protrusions located on the back side120B of the back-plate120which are located in a determined position near the first side face120′ and/or the second side face120″ if the back-plate120. The first positioners128may be oriented in the direction of the back side100B of the lining board100, or in other words, protrusions oriented away from the lining tile110. Said first positioners128may be separately fixed to the back-plate120, but more preferably said first positioners128are fixed portions of the back-plates120and formed of the back-plate120, for example, by punching said portion with the exception of one edge off the back-plate120and by bending it in the shape of a protrusion of the desired shape. The first positioners128align the angle plate200in the height direction of the upper edge120′″ and the lower edge120′″ of the back-plate120when assembling the lining board arrangement10.

Furthermore, in the embodiment ofFIGS.1A-C, the first positioners128have a plane surface128A preferably substantially vertical relative to the back surface120B of the back-plate120, which allows the positioning of the angle plate200at a determined distance from the back surface120B of the back-plate120in a direction determined by the plane surfaces128A in the first positioners128when assembling the lining board arrangement10. Said determined distance may be e.g. 0-20 mm, preferably 0-5 mm.

Furthermore, in the embodiment ofFIGS.1A-C, the first positioners128are integrated into said hangers126which are located near the first side face120′ and/or the second side face120″ of the back-plate120, whereby the hangers126thus located near the first side face120′ and/or the second side face120″ of the back-plate120are configured to operate as hangers126and a section of the hangers126is configured to operate as the first positioners128. In the embodiment ofFIGS.1A-C, the section of the plane surface of the hanger126, which is located vertically relative to the back surface120B of the back-plate120, is configured to operate as the first positioner128.

The angle plate200of the lining board arrangement10of the figures, such as e.g. a bent steel plate, is intended for being mounted on the back side120B of the back-plate120of the back-plate120of the lining board100, wherein the angle plate200is located near the first side face120′ or the second side face120″ of the back-plate120. InFIGS.2A-C, the angle plate200is shown separate from the lining board100for clarity.

Furthermore, the lining board100of the lining board arrangement10and the angle plate200to be mounted to it are intended to be located in the wall sections of the building being at an angle relative to each other, such as to the window recesses or the corners of the building. To the angle plates200to be located to window recesses are mounted i.e. positioned and fixed typically lining tiles110for forming a facade in the window recess. The lining tiles100to be located on both sides of the building corners are mounted i.e. positioned and fixed relative to each other by means of the angle plate200.

Furthermore, the angle plate200of the figures comprises second positioners210corresponding to the first positioners128of the back-plate120. The angle plate200comprises a first side202where said second positioners210are located. Said second positioners210may be mounted to the angle plate200separately but, more preferably, said positioners210are fixed sections of the angle plate200and formed in the angle plate200, wherein the second positioner210is a slot210having an open end, or an elongated slot210having an open end, on the first side202of the angle plate. The slot having an open end or the elongated slot having an open end allows the positioning of the angle plate200in a determined position relative to the first side  face120′ or the second side face120″ of the back-plate120when assembling the lining board arrangement10.

Furthermore, in the embodiment of the figures, the angle plate200includes grippers220. The angle plate200comprises a second side204where said grippers220are located. The grippers220are protrusions oriented away from the plane surface formed by the second side204into the direction of the lining tiles110to be mounted, or in other words, the protrusions are directed away from the wall or window recess of the building. The angle plate200of the figures is used in window recesses which are lined with lining tiles110. Said grippers220may be separately mounted to the angle plate200, but more preferably said grippers220are fixed portions of the angle plates200and formed of the angle plate200, for example, by punching said portion with the exception of one edge off the angle-plate200and by bending it in the shape of a protrusion of the desired shape. The gripper220is configured to grip the adhesive mass130for mounting the lining tile110to the back-plate120.

In an embodiment, instead of the grippers220in the angle plate200, the angle plate200includes third positioners on the second side204of the angle plate200. Said third positioners are not shown in the figures. Said embodiment is used when the angle plate200is located in the corner of the building, wherein two adjacent lining boards100located on both sides of the corner are positioned and fixed relative to each other. The construction of the third positioners is equivalent to that of the above-mentioned second positioners210, but the third positioners are configured to correspond to the second lining board100, or in more detail, to the positioners128of the second lining board100, and thus to align the lining board100corresponding to the angle plate200relative to each other.

In an embodiment, the second side204of the angle plate200does not comprise grippers220nor third positioners, but the second side204is configured to operate as a protective plate of the window recess, wherein no lining tiles110nor second lining board100is thus mounted to the angle plate200.

The lining board100is manufactured as follows. The lining tiles110are positioned on a manufacturing platform with their facade surfaces112facing down, at a distance from each other determined by a desired gap. In said positioning, a meshy panel guide, for example, may be utilised, having longitudinal and transverse rods that define the mutual positioning of the lining tiles110. When a panel guide is used, the lining tiles110may be put in place either by hand or  automatically with the aid of a robot, for example. Alternatively, the positioning of the lining tiles110may be carried out automatically without a special panel guide by means of a robot, only.

When the specified lining tiles110included in the lining board100to be manufactured have been set in place, adhesive mass130is fed onto the side faces110′-110′″ of the adjacent lining tiles110, wherein said adhesive mass130, as it is curing, fixes the adjacent lining tiles110to each other. The lining tiles110may comprise sockets on the sides110′-110′ of the lining tile, on the back side of the lining tile110, in which the adhesive mass is fed, wherein the socket and the adhesive mass fed to it enable the mounting of the lining tiles very near each other. Said sockets are not shown in the figures and they will not be discussed here in more detail.

Before the adhesive mass130cures, the back-plate120is put in place such that the grippers122are positioned between the lining tiles110, where the adhesive mass130is located, whereby the grippers122thus grip to the adhesive mass130. In such a case, the adhesive mass130, as it is curing, secures the tiling formed by the lining tiles110to the back-plate120through the adhesive mass130and the grippers122, the back-plate120forming a frame structure of the lining board100.

As adhesive mass130, cement-based grout, cement or epoxy based jointing mortars or plastic pastes may be used. To mount brick and lining brick panels, grout, jointing mortars, or plastic pastes may be used. Plastic pastes may be best suited for mounting plastic panels, but the use of grout or jointing mortar to mount plastic panels is also possible.

In the manufacture of the lining board100, a part of the lining tiles110may be left unmounted, wherein particularly a part of the lining tiles110of the lining board100to be positioned at an angle of the window recess or the corner of the building may be left unmounted. For example,FIG.1Ashows the embodiment in question wherein a part of the lining tiles110have been left unmounted on the second side face120″ of the back-plate120. Particularly, the lining tiles110being located near the first side face120′ and/or the second side face120″ of the back-plate120are left unmounted at the factory, if an angle plate200will be mounted closed to said side face120′,120′, and the lining tiles110are mounted to the lining board100at the construction site after the angle plate200has been mounted to the lining board100. For example, the lining tiles110to be located to window recesses and the lining tiles110of the  lining board100being at an angle relative to them may then be located specifically relative to each other in the mounting stage considering dimensional inaccuracies created in the construction stage of the building or, for example, the lining tiles110of the lining board100to be located on both sides of the corner of the building may then be located specifically relative to each other considering dimensional inaccuracies created in the construction stage of the building.

The lining board arrangement10is mounted as follows in accordance with a method. The lining boards100and the angle plates200are manufactured at a factory. The lining boards100and the angle plates200are transported to a mounting site. The lining tiles110are transported to the mounting site.

Furthermore in the mounting stage, hanging rails, to which the hangers126of the lining board100correspond, are mounted to the walls of the building. The lining board100is set by its hangers126to be supported by the hanging rails on the wall of the building.

Furthermore in the mounting stage, the angle plates200are positioned to those lining boards100which are located near the window recesses or corners of the building. The angle plate200is positioned to the lining board100such that the second positioners210of the angle plate200correspond to the first positioners128of the back-plate120, whereby the angle plate200retains its vertical position relative to the lining board100. The angle board200is positioned relative to the corner or the window recess of the building such that the angle plate200is specifically in line with the angle in the building, whereby the angle plate200is further in a determined position relative to the first side face120′ or the second side face120″ of the back-plate120.

Furthermore in the mounting stage, the angle plate200positioned to the lining board100is attached to the lining board100e.g. by an adhesive material, i.e. installation adhesive, and/or mounting members, such as e.g. drill screws. The adhesive is located between the angle plate200and the lining board100, whereby the angle plate200is fixed to the lining board100. The mounting members may, depending on the situation, be mounted from the facade side100F or the back side100B of the lining board100.

Furthermore in the mounting stage, the lining tiles110are fixed to the angle plate200by an adhesive mass130before mounting the angle plate200and/or after having mounted the angle plate200to the lining board100. The lining tiles110having possibly left unmounted in the manufacturing stage of the lining board100are mounted in the same mounting stage with  the lining tiles110for being fixed to the angle plate200, whereby the unmounted lining tiles110may be positioned specifically relative to the lining tiles110to be located to the angle plate200considering e.g. dimensional inaccuracies created in the construction stage of the building. It is possible to cut the lining tiles110to be mounted to the lining board100and the angle plate200to specific size before mounting them to the lining board100or the angle plate200.

According to another method, the mounting order of the mounting stage is as follows. The lining boards100and the angle plates200are manufactured and transported to a mounting site. The lining tiles110are transported to the mounting site. Said hanging rails are mounted on the walls of the building. The angle plate(s)200is/are positioned and attached to the lining board100, wherein the position of the angle plate200relative to the first side120′ and/or the second side120″ of the back-plate120is determined in a specified manner, such as e.g. based on the measurement of the building. The lining tiles110are fixed to the angle plate200by an adhesive mass130before mounting and/or after having mounted the angle plate200to the lining board100. The lining tiles110having possibly left unmounted in the manufacturing stage of the lining board100are also mounted in this stage, and it is possible to cut the lining tiles110to be mounted to the lining board100to specific size before mounting them to the lining board100. The lining board100, to which is mounted the angle plate200, is mounted to be supported by the hanging rails mounted to the building wall by the hangers126of the lining board100.

If necessary, it is possible to cut the lining tiles110to specific size before mounting them to the lining board100or the angle plate200to consider the dimensional inaccuracies created in the construction stage of the building. The position of the angle plate200relative to the lining board100is determined at the mounting site, wherein possibly cut-to-size lining tiles110are mounted in place of the lining tiles110unmounted to the lining board100, the size being based on the position of the angle plate200relative to the lining board100.

It is possible to cut the lining boards100to size, if necessary, from the first side120′ or the second side120″ of the lining board100before mounting and/or after having mounted the lining board100to the wall.

Those skilled in the art will find it obvious that, as technology advances, the basic idea of the invention may be implemented in many different ways. The invention and its embodiments are thus not restricted to the examples described above but may vary within the scope of the claims.
