Definitions

• the invention relates to a building block for the erection of different types of walls, said building block being formed substantially as a rectangular parallelepiped having a top side, a bottom side opposite the top side, a first gable side, a second gable side opposite the first gable side, and two opposite faces connecting the gable sides, wherein said top side is provided with a longitudinal first recess and said bottom side is provided with a longitudinal ridge corresponding to the recess.
• Building blocks formed as a rectangular parallelepiped might be the most common building component. This category comprises bricks made of clay, large or small concrete blocks and different types of lightweight blocks of insulating material. Most types of building blocks are joined by means of a joining material, such as mortar.
• a joining material such as mortar.
• One common drawback with this type of building blocks is that a joining material must be used to provide stable and lasting building structure assemblies.
• building blocks having opposite faces formed for engaging one another can be found. The engagement can be so strong that the joining material can be excluded. This type of building block is particularly useful for garden walls and similar building structures.
• One prior art building block disclosed in SE508736 comprises opposite faces having parts for engaging each other for locking in the longitudinal direction of the building blocks when the building blocks are positioned on top of one another.
• the parts are arranged along two long side faces of the build- ing block and with one intermediate and longitudinal mortar channel for receiving mortar when the building blocks are joined. Similar mortar channels can also be formed in opposite short side faces of the building blocks.
• the shape of the parts makes it possible to interlock building blocks perpendicular to each other to provide corners.
• One problem with the building blocks disclosed in SE508736 is that relative transverse displacement of building blocks is permitted. Hence, in consequence thereof and due to other reasons it is necessary to use the mortar channels and obtain fixed positions of the building blocks.
• GB2060026 discloses a building block family. The building blocks can be fitted together quickly and are of low weight since they are formed with internal cavities and are relatively thin (40 mm). Mortar is not required, but glue or another adhesive material is.
• Opposite faces of a basic building block in the family are formed with a continuous longitudinal ridge and a longitudi- nal recess, respectively.
• the ridge as well as the recess is provided with bevelled edges.
• the ridge is divided into two portions, wherein one can be received in the recess when the building blocks are angled.
• One drawback is that a great number of differently formed blocks are included in the family and are required to obtain the desired flexibility and stability and the desired appearance.
• One particular embodiment of the building block is used at corners.
• This embodiment of the building block can not be used anywhere else than at the comers, as the recess does not extend along the entire building block and thus prevents inde- pendent positioning of adjacent building blocks.
• One object of the invention is to overcome the above-mentioned prob- lem and drawbacks. This object is obtained by forming the building block with a ridge and a corresponding recess, wherein the width of the ridge corresponds to the width of the recess.
• the ridge is divided into at least one fist ridge portion extending from the first gable side and a second ridge portion arranged at a distance from the first ridge portion and at a distance from the second gable side, wherein the length and position of the second ridge portion corresponds to the width of the recess, so that the second ridge portion of an upper building block totally can be received in a lower building block arranged perpendicular to the upper building block.
• the juxtaposition of building blocks on top of one another provides transversal fixing entirely without mortar or any other jointing material.
• the juxtaposition of building blocks at a corner provides fixing entirely by interlocking. Building blocks of various width can be provided.
• building structures can be erected and also disassembled very quickly. This possibility can be used for example when emergency dwellings or any other type of elementary homes are needed promptly.
• the ridge as well as the recess suitably extends centrally in the top side and the bottom side, respectively, between the gable sides.
• One advan- tage with this embodiment is that the building blocks can be turned 180° and still be positioned on top of each other while maintaining accurate lateral position.
• One single embodiment of the building blocks can be used freely in different positions, such as corners.
• the recess is formed with a depth exceeding the hight of the ridge, leaving an open space between the bottom of the recess and the ridge when two building blocks are positioned on top of each other.
• the open space can be used for piping and fitting other types of connections. For applications using joining material this can also be arranged in the open space, possibly together with reinforce- ment.
• the lengths of the first ridge portion and the second ridge portion can be selected in different combinations to obtain different structure designs. According to one embodiment the lengths are selected, so that the total of the distance between the first ridge portion and the second ridge portion, the length of the second ridge portion and the distance between the second ridge portion and the adjacent gable side is constant, independent of the width of the building block.
• building blocks having a different width can be assembled perpendicularly from a wall of standard building blocks while maintaining an effective locking.
• the lengths are selected, so that the total of the distance between the first ridge portion and the second ridge portion, the length of the second ridge portion and the distance between the second ridge portion and the adjacent gable side equals the width of the building block.
• building blocks having a specific width can be assembled in different configurations while maintaining an effective locking. Automatic juxtaposition of building blocks for walls and other structures can be found. To facilitate such automatic juxtaposition at least one gable side can be formed with a recess or an indentation, extending in a direction from the top side to the bottom side.
• the faces at a corner of assembled building blocks can be completely smooth.
• the ridge can be formed somewhat tapered in a direction out from the bottom side of the building block. This facilitates the positioning of a building block on top of another, since the ridge will be guided into the recess.
• the widths of the ridge and the recess are small in comparison with the width of the building block.
• the building blocks can be formed in different materials having different prominent characteristics.
• a suitable material is haydite concrete comprising haydite material pellets. The pellets are joined by cement or similar material.
• Haydite can be used for the construction of walls which are load-bearing as well as insulating. In this context, haydite is also a homogenous material, wherein no thermal bridges or similar can appear in the material also having excellent heat insulating properties.
• So called lightweight concrete can also be used for construction material. Lightweight concrete has favourable load-bearing properties but has poorer insulating effect in certain circumstances. If a favourable insulating effect is to be obtained, without any load-bearing requirements, different types of cellular plastic can be used. All the above-mentioned materials can be moulded or processed to desired shape. Other embodiments are evident from the following detailed description and enclosed drawings.

• THE INVENTION Fig. 1 illustrates one embodiment of a building block 10 according to the invention in the shape of a rectangular parallelepiped having one rectangular top side 11 (not visible) and one opposite rectangular bottom side 12. The top side and the bottom side are connected by two opposite short side faces and two opposite long side faces.
• the building block of Fig. 1 is illustrated upside-down in relation to the intended use.
• the bottom side is formed with an elongated ridge, which is divided into a first ridge portion 13 and a second ridge portion 14.
• the first ridge por- tion 13 extends from a first short side and the second ridge portion 14 is detached between the first ridge portion 13 and the second short side.
• an indentation 15 is formed in the first short side face, which indentation 15 extends over the entire short side face from the top side to the bottom side.
• the inden- tation extends only over one part of the short side face. The function of the indentation is primarily to facilitate automatic juxtaposition of building blocks.
• On the top side 11 an elongated recess 16 extends between the short sides (see also Fig. 4 and Fig.
• the recess is formed with a width corresponding to the width of the ridge portions.
• ridge portions as well as the recess extend centrally along the bottom side and top side, respectively.
• the building block 10 is also formed with plane faces or long side faces 19, extending between the top side 11 and the bottom side 12.
• Fig. 2 illustrates the building block of Fig. 1 from another angle.
• the first ridge portion 13 and the second ridge portion 14 project from the bottom side 12 of the building block.
• the recess 16 extends continuously from one short side to the other and is formed with a depth exceeding the height of the ridge portions 13, 14 over the bottom side 12.
• a building block arranged on top can be positioned freely in the Ion- gitudinal direction of the building block in relation to an underlying building block.
• the building block serves as a unit block or a module block, which can be used in any position, also at corners. It is also possible to cut the building block to practically any length.
• Fig. 3 illustrates one embodiment of the positions of the first ridge portion 13 and the second ridge portion 14 on the bottom side 12 of the building block.
• the ridge portions are positioned centrally on the bottom side but other embodiments are conceivable as well.
• the second ridge portion 14 is arranged at a distance from the first ridge portion 13 and the closest side edge, respectively, so that a second building block arranged perpendicularly totally will receive the second ridge portion 14 in its recess 16 (see also Fig. 11 and Fig. 12).
• the indentation 15 can be formed with bevelled or inclined side edges.
• the form of the indentation is suitably selected in respect of the design of the machine used for juxtaposition.
• the dimensions of the building block can be varied more or less freely within the scope of the material strength. From Fig. 4 the central arrangement of the recess 16 and the second ridge portion 14 in the building block 10 is evident. The remaining of the top side 11 and the bottom side 12 is formed completely plane for favourable contact between building blocks positioned on top of each other. The plane part of the top side and the bottom side beyond the ridge and the recess, re- spectively, is formed with a relatively large surface, which can bear extensive vertical forces.
• the ridge portions 13, 14 is formed with a height h.
• the depth of the recess and the height of the ridge can vary according to current application.
• Fig. 5 illustrates how corners can be built by means of building blocks according to the invention. Suitably, those building blocks which are at the edge of the corner are positioned so that the indentation 15 faces inwards, wherein a completely smooth outer surface of the wall is obtained.
• the recess 16 extends along the entire building block and is sufficiently deep for piping, also when the ridge portions of a building block arranged on top are received therein.
• Fig. 8 illustrate a first system of building blocks formed in accordance with the invention.
• the sum of the distance between the first ridge portion 13 and the second ridge portion 14, the length of the second ridge portion 14 and the distance between the second ridge portion 14 and the adjacent short side equals D.
• the second ridge portion 14 is arranged centrally in an area between the first ridge portion 13 and the nearest short side.
• the width has been reduced to W2, while the distance D remains constant.
• the position of the second ridge portion 14 remains unchanged.
• the width is reduced further to W3, while the distance D remains constant.
• the different building blocks of the first system can all be combined with the stan- dard dimension, when the building blocks are assembled in a T-shape or an L-shape having a connecting wall portion connected perpendicularly to a first wall portion.
• L D + the length of the first ridge portion 13.
• the width has been reduced to W4, wherein the distance between the first ridge portion 13 and the second ridge portion 14, the length of the second ridge portion 14 and the distance between the second ridge portion 14 and the adjacent short side simultaneously has been reduced to V1.
• W4 V1.
• L V1 + the length of the first ridge portion 13, which length thus being constant, independent of the length of the building block.
• FIG. 11 illustrates schematically how two building blocks can be positioned on top of one another in a right-angled relation.
• the first ridge portion 13 and the second ridge portion 14 of the upper building block illustrated in Fig. 11 are lowered into the recess 16 of the lower building block illustrated in Fig. 11.
• Both of the building blocks are positioned so that the short side faces having the indentations 15 are turned inward from the corner and, consequently, are not visible.
• the first ridge portion 13 can be formed similar to the embodiments described above.
• the building block is solid and is formed in haydite or any other material having corresponding heat insulating properties. No passages or portions of a different material affect the properties of the building block, neither in respect of heat insulation, ability to bear loads or the possibilities of cutting the building block into desired length. Due to large plane surfaces on the top side and the bottom side beyond the ridge and the recess, respectively, extensive loads can be carried without reinforcement. The large plane surfaces make it also possible to ap- ply girders or specifically designed building blocks above windows and doors.
