Description

P29696NL00/RR
Title: Building block having a transverse groove-shaped channel in its upper or lower face.
The invention relates to specifically shaped building blocks for use in the building of walls in housing constructions and the like, in particular building blocks which are so large and/or heavy that they can or may not be placed and positioned manually on top of each other, but need to be handled with the aid of a lifting device. More in particular the invention 5 relates to such specifically shaped large and/or heavy building blocks which have been made out of sand-lime stone material or similar lightweight material.
When building a wall with traditional masonry, bricks are each time placed in a bed of mortar. This mortar bed has a thickness of approximately 10 mm. Tolerance differences between respective bricks and unflatness in the ground can easily be corrected by laying the 10 brick in the mortar and if necessary tapping on it with for example a trowel. When building a wall with sand-lime building elements, blocks are each time placed in a thin layer of suitable mortar. This thin layer of mortar has a thickness of approximately 2 mm. Tolerance differences between respective blocks and unflatness in the ground are now harder to correct. Laying the block in the thin layer mortar and tapping on it, has less effect since the 15 layer of mortar is thin.
For larger and/or heavier building blocks use is being made of mechanical lifting devices. For example nowadays more and more sand-lime building blocks are being manufactured and used which weigh between 100-400 kg. An example of such a large and/or heavy sand-lime building block is known from NL-1019290. These large and/or heavy 20 sand-lime building blocks can no longer be manually corrected in their relative position by laying them in the thin layer of mortar and/or tapping on them. Therefore, use is being made of small plastic pegs. The pegs are forced to a sufficient depth into the mortar joint which arises between two blocks placed on top of each other. Thus a desired correction in the relative position of the blocks can be obtained. After the thin layer of mortar has sufficiently 25 hardened the pegs can be removed again, while the blocks maintain their corrected relative position.
However, the thus trying to correct relative positions between large and/or heavy sand-lime building blocks has appeared to be quite difficult. On the one hand the large weight of the building blocks makes it difficult to start driving the pegs into the joint. On the 30 other hand in practice it has appeared that the mortar joints which remain after the blocks have been placed on top of each other, may locally have become thinner than the -2- mentioned 2 mm thickness of the original mortar layer. Sometimes they even have diminished locally to less than 0.5 mm. This makes it even more difficult or even impossible to start driving the pegs into the joints at specific aimed locations there along. The heavier the building block the more difficult it is to wedge it to its correct position with the aid of 5 driving pegs into the joints.
The present invention aims to at least partly overcome the abovementioned disadvantages or to provide a usable alternative. In particular the invention aims to provide a building block which is shaped in such a way that it can be easily corrected for in its position relative to other building blocks, even when the building block is relative large and/or heavy 10 and/or needs to be laid in a relative thin adhesive layer.
This aim is achieved by a building block according to claim 1. The block comprises upper, lower, side, front, and back faces. In the upper or lower face at least one grooveshaped channel is provided which lies at a distance from both side faces. The grooveshaped channel opens out towards the front and/or back face and extends in a transverse 15 direction of the block which is substantially perpendicular to the front and/or back face. The groove-shaped channel is designed and destined for forcing a positioning peg therein after two of these building blocks have been placed on top of each other with the groove-shaped channel being directed towards the joint which arises between the two building blocks. By driving the peg to a greater or lesser extent into the groove-shaped channel, the upper block 20 can be corrected in its position relative to the lower block. The groove-shaped channel has the advantage that no matter how small the joint may become because of for example a relative large weight of the blocks, it always remains possible to start driving the peg into the channel. Since the peg does not start to exert an upwards pressure on the upper block before it has been forced to a certain minimum depth into the groove-shaped channel, a 25 larger surface area is available for the peg to exert its upward pressure. Owing to this the risk of edge parts of the blocks breaking of at the location of where the pegs are forced into the joints is now minimized. Furthermore, the groove-shaped channel has the advantage of delimiting the peg sideways. Because of this the peg remains correctly positioned during its driving into the groove-shaped channel, which in turn makes it possible to accurately obtain 30 the aimed correction of the position of the upper block.
Instead of only one groove-shaped channel it is also possible to provide the upper or lower face with more than one transversely directed groove shaped-channel. Preferably at least one of the groove-shaped channels is provided at a central position in the upper or lower face. This central groove-shaped channel makes it possible to lift the entire upper 35 block with the aid of only one peg or to tilt the entire upper block somewhat around its longitudinal axis again with the aid of only one peg.
-3-
In a further embodiment the groove-shaped channel opens out towards both the front and back face and extends in the transverse direction of the block over the entire thickness of its upper or lower face. This makes it possible to force a peg into the channel from whichever side which at that moment is the most appropriate one. Also this provides for 5 more than enough available space/length for the peg to be forced into the channel in order to make the necessary correction.
Although the invention can also be used for relative small building blocks, like conventional bricks, it is most advantageous for blocks having a weight of more than 50 kg, in particular more than 100 kg, that is to say blocks having such dimensions and/or weight 10 that they need to be handled mechanically with a lifting device.
The block can be manufactured out of all kinds of materials. In particular however the invention is used for blocks which are manufactured out of lightweight materials which are to be connected to each other by means of an adhesive glue layer. More in particular the groove-shaped channel is provided in a block which has been manufactured out of a sand-15 lime stone or porous concrete.
Further advantageous embodiments are stated in the subclaims.
The invention also relates to a wall built up out of building blocks according to the invention, as well as to a method for building such a wall.
20 The invention shall be further clarified below with reference to the drawings, in which:
Fig. 1 shows a perspective view of an embodiment of the block according to the invention having one central groove-shaped channel in its upper face;
Fig. 2 shows a front view of the building of a wall out of a plurality of the blocks of fig.
1; 25 Fig. 3 the placing of pegs in the channels; and
Fig. 4 the removing of these pegs after the mortar in the joint has hardened.
In fig. 1 the entire building block has been indicated with the reference numeral 1.
The block 1 is made out of sand-lime stone, weighs more than 50 kg, is rectangular in shape 30 and comprises an upper face 2, a lower face 3, side faces 4, a front face 5 and a back face 6. In the upper face 2 a groove-shaped channel 8 has been saved. The channel 8 lies at a central position of the upper face 2 at a distance from the side faces 4 and extends in the transverse direction 9 of the block 1.
The channel 8 has a length I which is equal to the thickness of the block 1 and thus 35 extends over the entire thickness of the block 1 and opens out towards the front face 5 and to the back face 6. The channel 8 has a width x which here is chosen to be smaller than 60 mm, and in particular to lie between 30-40 mm. Furthermore the channel 8 has a depth y -4- which here is chosen to be between 1-3 mm. Seen in cross section the channel 8 has a horizontal flat bottom wall 8a and two vertical upstanding side walls 8b.
Besides the central transverse channel 8 in the middle of the upper face 2, the block 1 also comprises two recesses 10 which have likewise been saved out in the upper face 2.
5 Each recess 10 lies at a respective corner position of the block 1, that is to say at the transition between the upper face 2 and the corresponding side face 4.
The recesses 10 have a length which again is equal to the thickness of the block 1 and thus also extend over the entire thickness of the block 1 and open out towards both the front face 5 and to the back face 6. The recesses 10 have widths which here are chosen to 10 be approximately equal to x, and thus to also be smaller than 60 mm and in particular to lie between 30-40 mm. Furthermore, the recesses have depths which here are chosen to be substantially equal to y, that is to say lie between 1-3 mm. Seen in cross section the recesses 10 each have a horizontal flat bottom wall 10a and one vertical upstanding side wall 10b.
15 The respective faces of the block 1 might be provided with suitable further profiles like the shown tongue-groove shaped parts 14, 15 on the upper, lower and side faces 2, 3, 4 for gripping into complementary tongue-groove shaped parts of neighbouring blocks.
In fig. 2 a part of a wall panel 20 is shown which is in the process of being built up out of a plurality of the blocks 1. As can be seen the upper faces of the blocks T, 1" and the 20 side face of the block 1of the wall panel 20 are provided with a thin layer of mortar 21. A new block 1 is placed on top of this mortar layer 21 with the aid of a crane or other mechanical lifting device 22. If, after the placing with the aid of the mechanical lifting device 22, this newly placed block 1 needs to be corrected somewhat in its position, then one or more pegs 24, 25, 26 are forced to a bigger or lesser extent into the groove-shaped 25 channels 8 and recesses 10 of the blocks T and 1" in the layer directly beneath the newly placed block 1 (see fig. 3). Forcing for example the left peg 25 into its channel 8 has the effect of lifting up the left side of the new block 1 which results in a sideways movement of its upper face 2. Forcing in one or more of the other pegs each has its own characteristic resulting repositioning of the block 1 relative to the lower layer of blocks T, 1" and relative to 30 its adjacent block 1Thus, if deemed necessary, each block 1 can be easily and properly corrected for in its position after it has been placed in the layer of mortar 21. Fig. 4 shows the situation where the wall is finished and wherein, after each of the building blocks if necessary has been corrected for in its relative position, the pegs have been removed and the channels have been filled-up with mortar or other curable material.
35 Besides the embodiments shown numerous variants are possible. For example more than one groove-shaped transverse channel might be provided. In the alternative or in addition also channels might be provided in the lower face. In fact, although each of the -5- present drawings shows building blocks having the groove-shaped transverse channels provided in their upper face, it is advantageous for the channels to be provided only in the lower face since with such an embodiment it is easier to place uniform mortar layers on the flat top faces of the blocks with substantially continuous layer thicknesses. In another 5 embodiment the channels may also extend over only part of the thickness of the block, as long as they remain open towards either the front or the back face and as long as they remain long enough in order to be able to force a peg sufficiently deep into it. Instead of using sideways open recesses at the corner positions for forcing a peg into, it is also possible to provide sideways closed groove-shaped channels near these corner positions of 10 the block for being able to force a peg into. The groove-shaped channels may have different widths depending on the widths of the pegs to be used. Also it is possible to make the groove-shaped channels with other types of cross sections, like for example a V-shaped cross section. Besides being used for sand-lime stone blocks, the invention can also be used for building blocks made of other materials like for example concrete, more in particular 15 lightweight porous concrete. Preferably the blocks from these other materials have dimensions such that they also need to be handled mechanically since they are too heavy to be lifted up and placed by hand.
Thus according to the invention an economic and user-friendly building block is provided which can easily be corrected for in its position after it has been placed 20 mechanically in a thin layer of mortar.
