Abstract
1. Building system for a wall 2.1 A building system for a wall that uses shaped blocks that can be joined to each other by dry walling [non-mortared] methods is already known. In this system, one supporting surface has a groove and the other supporting surface has a spline that is matched to said groove. A disadvantage in this is that, for example, precise positioning cannot be ensured when the shaped blocks are laid one on top of the other because of dirt and foreign bodies, so that the blocks can shift in the longitudinal direction. This makes additional work necessary on the finished wall and results in an uneven appearance that is caused by the joints being off-set. It is the task of the present invention to simplify overall construction of the wall and guarantee the optimal appearance of the completed wall.
2. To this end, provision is made such that each groove (10) or each associated spline (2) is provided with notches or with projections (3) that form a positive fit with these, as well as with continuous fill cavities in the blocks, these cavities being formed as a middle opening (4) and semi-circular dished end openings that (5) that are associated with these on the opposing abutting surfaces.
2.3 The present invention permits very simple erection that satisfies all demands with respect to the appearance of the masonry and which, in addition, can be effected very quickly.

Description
~l~S~6~
A Bu~ldlng System for a Wall The present lnventlon relates to a bulldlng ~ystem for a wall as set out ln the preamble to Patent Clalm 1.
DE 14 09 139 and DE 27 01 771 descrlbe shaped blocks of this kind, wlth which lt is posslble to bulld a wall uslng dry walling methods.
1~ However, there are dlsadvantages to uslng these known, shaped blocks, and these do not permlt optlmal constructlon of a wall.
In the flrst lnstance, there ls a danger that the shaped blocks that are to be laid one on top of the other, or whlch have already been lald ln thls manner, wlll shlft long1tudlnally because of faulty holdlng means.
When thls hArp~ns, even the smallest shifts caused, for example, by forelgn bodles collectlng ln the vlclnlty of the abuttlng surfaces, can become so large as a result of accumulatlon that ultlmately lt becomes lmposslble achleve a preclse structure that ls of the e~act dlmenslons that are requlred.
In thls case, the partlcles of dlrt between the butt ~olntc can result ln faulty seallng that can affect the resultlng wall, ln partlcular wlth respect to lts thermal lnsulatlng propertles.
In addltlon, ln the known shaped blocks, the flll cavltles are formed as contlnuous openlngs so that when the shaped blocks are laid so as to be staggered, the flll cavlty of the upper block lles above the flll cavlty of the lower lock that ls arranged on the opposlte a~uttlng surface.
Should lt be necessary to use a half bloc~, for e~ample, in order to deflne an openlng for a wlndow or a door, the thlckness of the ~1 7~i61 material between the two fill cavities is halved, for all practical purposes, and this results in a considerable weA ke~; ng of the block as a whole. This is important mainly if such an area is to be used as a supporting surface, for example, for a window or door lintel.
For this reason, it is the task of the present invention to create a building system of the type described above, the shaped blocks of which can be laid very precisely under all conditions and which has an optimal load-bearing capacity in every case.
This problem has been solved by a building system that displays the distinguishing features set out in Patent Claim 1.
The block is locked in the longit~ n~l direction by the notches in the-yro~ve that is f~chioned in one supporting surface of the block and the projections in the associated spline of another adjoining block, which corresponds to the notches so as to form a positive fit.
This means that any displacement of the block resulting, for example, from particles of dirt as discussed above, and which could bring about a change in dimensions, is thus precluded, and this ensures not only an even masonry ~pre~ance, which is determined by the joints, but also eliminates any subsequent work caused by the need to shorten the last block in a course.
The advantages that result from this are clear to see.
It can be advantageous to provide a seal between the supporting surfaces of blocks that face each other and, optionally, between the abutting surfaces of adjacent blocks.
When this is done, the seal between the supporting surfaces can be in the form of a strip and be matched to the shape of the groove or spline, respectively.

The block is locked in the longit~ n~l direction by the notches in the-yro~ve that is f~chioned in one supporting surface of the block and the projections in the associated spline of another adjoining block, which corresponds to the notches so as to form a positive fit.
This means that any displacement of the block resulting, for example, from particles of dirt as discussed above, and which could bring about a change in dimensions, is thus precluded, and this ensures not only an even masonry ~pre~ance, which is determined by the joints, but also eliminates any subsequent work caused by the need to shorten the last block in a course.
The advantages that result from this are clear to see.
It can be advantageous to provide a seal between the supporting surfaces of blocks that face each other and, optionally, between the abutting surfaces of adjacent blocks.
When this is done, the seal between the supporting surfaces can be in the form of a strip and be matched to the shape of the groove or spline, respectively.
2 ~ ~5~6 1 Because it is soft, the particles of dirt that lie on the supporting surfaces can be pressed into the seal, so that when the blocks are laid up in courses there will be no significant changes in dimension. The height of the spline or the depth of s the groove is to be matched to the thickness of the seal. The surface of the seal can be either smooth or rippled.
It is particularly advantageous if a sealing strip or, as an equivalent to this, a sealing band can be unrolled from a roll and then cover a complete course of adjoining blocks.
It is, however, also possible to provide a rigidly attached seal on the appropriate side of each block, said seal being secured by adhesive, for example.
Usually, however, the blocks are joined to each other by adhesive, when a suitable applicator automatically lays a thin bed of adhesive on the upper surface of the block.
In particular, a very efficient method of working will result, given the formation of the notches and projections at identical levels relative to the associating grooves or splines.
Vertical grooves can be provided in the area of the abutting surfaces, and after assembly of the blocks these can be sprayed with a sealant such as silicone. However, it is also possible to insert se~l ;ng strips that are of a suitable material at these locations.
According to another concept of the present invention, provision is made such that a corner block can be inserted for the corner area of a wall, one face of such a block being configured not as an abutting surface, but rather as a flat, exposed surface.
In order to make it possible to arrange the butt joint between two blocks exactly in the middle above a block that is laid off-set below them, and thereby achieve an acceptable appearance, filler blocks are arranged between a corner block and a block that it is set at an angle to this. By doing this, the size difference relative to the mid-point that results from the offset of the sides between the groove of one abutting surface and the spline of the other abutting surface is evened out.
Other advantageous versions of the present invention are described in the secondary claims.
Embodiments of the present invention will be described in greater detail below on the basis of the drawings appended hereto. These drawings show the~ollowing:
Figure 1: part o~'the cornp~ area of a wall according to the present i~v~lLion, Figure 2: a plan view o~ a shaped block;
Figure 3: a cross-section through a block on the line III-III in Fiqure 2;
Figure 4: a block as viewed from the front;
Figure 5: another embodiment of the present invention showing two blocks in plan view.
Figure 1 shows the corner area of a wall made up of a multiplicity of shaped blocks 1 that are laid in courses one above the other.
Each shaped block has a groove 10 and a spline Z on one supporting surface, the supporting surface having the spline 2 forming the upper side.
The spline 2 and the groove 10 are both matched to each other with respect to their shapes and their dimensions, so that when the blocks l are laid one above the other, a positive fit will result.
This also applies to the projections 3 that are formed on the sides of the splines 2 and the notches 12 that are adjacent to the groove 10; when the blocks 1 are laid one on top of the other these engage in each other and ensure that the blocks are locked in the longit~ direction.
The projections 3 and the notches 12 are arranged so as to be symmetrical relative to both the longitllA; n~ 1 and lateral axes of the block.
The embodiment that is shown in Figure 5, in which each a~utting surface has a recess 17 and a raised area 18 in the outer edge area, makes it particularly simple to m~nirll~te the blocks when they are being assembled. When one block is laid on a lower lock it is a matter of choice as to which of the two long sides is Z5 used as the exposed side, i.e., the shaped block can be rotated - through 180 degrees in the plane.
To this end it is necessary that, at one end, there be a recess and, at the other end, a raised area in the edge areas of the opposing abutting surfaces that are associated with a long side;
it is best that each of these extend to the whole height of the block l.
It is advantageous if the depth of the recess be somewhat greater than the height of the raised area that fits in it. This will s result in a gap 19 that can be filled with an adhesive or with a sealant, for example.
In addition, each block 1 incorporates fill cavities; these are in the form of continuous middle openings 4, and semicircular, dished openings S in the area of each abutting surface.
As is shown in Figure 1, supports 11 consisting, for example, of metal tubes, can be inserted into these fill cavities, which lie above each other when the bloc~s 1 are laid so as to be staggered, and thus result in cavities that extend to the whole height of the wall; these supports are then anchored to the floor at the bottom and similarly secured at the top so as to satisfy all demands with re~L to static stability.
One of the abutting surfaces of each block l is provided with a spline 6, whereas the other-end that is opposite to this incorporates a groove that is matched to this spline 6; this results in a positive ~it that, on the one hand, ensures positional stability and, on the other, makes it impossible to see through the joint. In this connection, it should be noted that each outer edge of the block 1 is formed as a bevelled face 14, which has a particularly advantageous effect on the overall visual appearance of the wall.
In order to save weight, the blocks 1 have holes 13 which, in the present example, are in the form of blind holes although, of course, they can be continuous and can be of any cross section.
Figure 1 also shows that in the corner area of the wall, corner blocks 8 are used, and essentially these are assembled in the same way as the blocks 1, although they are made smooth in the area of an abutting surface that forms a face end, which is to say that they have no end opening 5 at this location.
The supporting surfaces that are associated with this outer area that forms a visible face are provided with openings 15 through which an additional reinforcement can be introduced to the whole height of the wall in order to accommodate the increased loads in the corner area.
The corner block 8 that is used can be fixed by means of a centring pin 16 that is installed in the area adjacent to the openings, and this corner bloc~ 8 also incorporates a corresponding centring hole.
A filler 9 is used between a corner block 8 and the block 1 that abuts against it at a right angle and this fi~s positively into the associated groove 7 of the block 1 because the abutting surface that faces-the block 1 is configured as a spline. For the rema;n~, the supporting surfaces of the filler 9 are configured as either splines or as grooves.
The present invention is characterized, in particular, in that for all practical purposes a wall can be erected with no additional work, said wall forming an exposed surface that is visually acceptable; such a wall can be erected extremely quickly and, because of this, in a very economical manner.

In order to make it possible to arrange the butt joint between two blocks exactly in the middle above a block that is laid off-set below them, and thereby achieve an acceptable appearance, filler blocks are arranged between a corner block and a block that it is set at an angle to this. By doing this, the size difference relative to the mid-point that results from the offset of the sides between the groove of one abutting surface and the spline of the other abutting surface is evened out.
Other advantageous versions of the present invention are described in the secondary claims.
Embodiments of the present invention will be described in greater detail below on the basis of the drawings appended hereto. These drawings show the~ollowing:
Figure 1: part o~'the cornp~ area of a wall according to the present i~v~lLion, Figure 2: a plan view o~ a shaped block;
Figure 3: a cross-section through a block on the line III-III in Fiqure 2;
Figure 4: a block as viewed from the front;
Figure 5: another embodiment of the present invention showing two blocks in plan view.
Figure 1 shows the corner area of a wall made up of a multiplicity of shaped blocks 1 that are laid in courses one above the other.
Each shaped block has a groove 10 and a spline Z on one supporting surface, the supporting surface having the spline 2 forming the upper side.
The spline 2 and the groove 10 are both matched to each other with respect to their shapes and their dimensions, so that when the blocks l are laid one above the other, a positive fit will result.
This also applies to the projections 3 that are formed on the sides of the splines 2 and the notches 12 that are adjacent to the groove 10; when the blocks 1 are laid one on top of the other these engage in each other and ensure that the blocks are locked in the longit~ direction.
The projections 3 and the notches 12 are arranged so as to be symmetrical relative to both the longitllA; n~ 1 and lateral axes of the block.
The embodiment that is shown in Figure 5, in which each a~utting surface has a recess 17 and a raised area 18 in the outer edge area, makes it particularly simple to m~nirll~te the blocks when they are being assembled. When one block is laid on a lower lock it is a matter of choice as to which of the two long sides is Z5 used as the exposed side, i.e., the shaped block can be rotated - through 180 degrees in the plane.
To this end it is necessary that, at one end, there be a recess and, at the other end, a raised area in the edge areas of the opposing abutting surfaces that are associated with a long side;
it is best that each of these extend to the whole height of the block l.
It is advantageous if the depth of the recess be somewhat greater than the height of the raised area that fits in it. This will s result in a gap 19 that can be filled with an adhesive or with a sealant, for example.
In addition, each block 1 incorporates fill cavities; these are in the form of continuous middle openings 4, and semicircular, dished openings S in the area of each abutting surface.
As is shown in Figure 1, supports 11 consisting, for example, of metal tubes, can be inserted into these fill cavities, which lie above each other when the bloc~s 1 are laid so as to be staggered, and thus result in cavities that extend to the whole height of the wall; these supports are then anchored to the floor at the bottom and similarly secured at the top so as to satisfy all demands with re~L to static stability.
One of the abutting surfaces of each block l is provided with a spline 6, whereas the other-end that is opposite to this incorporates a groove that is matched to this spline 6; this results in a positive ~it that, on the one hand, ensures positional stability and, on the other, makes it impossible to see through the joint. In this connection, it should be noted that each outer edge of the block 1 is formed as a bevelled face 14, which has a particularly advantageous effect on the overall visual appearance of the wall.
In order to save weight, the blocks 1 have holes 13 which, in the present example, are in the form of blind holes although, of course, they can be continuous and can be of any cross section.
Figure 1 also shows that in the corner area of the wall, corner blocks 8 are used, and essentially these are assembled in the same way as the blocks 1, although they are made smooth in the area of an abutting surface that forms a face end, which is to say that they have no end opening 5 at this location.
The supporting surfaces that are associated with this outer area that forms a visible face are provided with openings 15 through which an additional reinforcement can be introduced to the whole height of the wall in order to accommodate the increased loads in the corner area.
The corner block 8 that is used can be fixed by means of a centring pin 16 that is installed in the area adjacent to the openings, and this corner bloc~ 8 also incorporates a corresponding centring hole.
A filler 9 is used between a corner block 8 and the block 1 that abuts against it at a right angle and this fi~s positively into the associated groove 7 of the block 1 because the abutting surface that faces-the block 1 is configured as a spline. For the rema;n~, the supporting surfaces of the filler 9 are configured as either splines or as grooves.
The present invention is characterized, in particular, in that for all practical purposes a wall can be erected with no additional work, said wall forming an exposed surface that is visually acceptable; such a wall can be erected extremely quickly and, because of this, in a very economical manner.
