Definitions

  • Presented solution deals with a system for precise and fast wall construction without the need to use ready-mix mortars or polyurethane foams to glue coursing joints of construction elements.
  • Sidewall panels are formed by liapor concrete sandwich blocks designed for single-layer enclosing and backing masonry.
  • the tongue-and-groove system is implemented only in the side faces and is not self-locking in the wall body, therefore it ensures that the blocks are bound in single axis only. This system does not eliminate the need to use mortar for coursing joints during walling as such.
  • sandwich construction elements is the self-supporting sandwich panel made by gluing the OSB boards with insulation core made of expanded polystyrene. This system allows for rather rapid construction works. But for fixing in the wall framework are used masts and truss bearing beams made of solid wood. It has no integrated self-locking system of individual panels' interconnection and it does not solve preparation for installation of infrastructure networks.
  • Another method of buildings construction is represented by a group of thin-slab construction elements formed by a single material.
  • Example of such design is the concrete thin-slab shell blocks with rectangular locks on side walls. These locks do not solve self-locking properties. Blocks are conventionally laid on concrete mortar, with which the locks on side walls must also be filled. These blocks are mostly intended for supporting walls only, therefore they do not solve the shell construction as a whole.
  • the blocks are usually connected with the separate sandwich insulation system, which is attached as part of the wall from the outside or inside the supporting wall. The blocks as such do not solve the preparation for installation of the infrastructure networks and these - where possible - are implemented in another sandwich layer.
  • Example of this design are the construction shaped blocks made of expanded polystyrene, which by means of a special locking system are engaged into one another thus creating the enclosing walls and separating walls without the need to use any jointing materials.
  • Permanent formwork built by this design is filled with concrete mixture and creates a compact wall. Shaped blocks are not self-supporting and do not solve the infrastructure networks. Supporting element itself has no relation to the shaped blocks whatsoever.
  • a separate group is represented by the dry masonry systems equipped with special locks shaped as coaxial cylinders.
  • Example of such system is the system of dry walling blocks where the basic construction elements are blocks made of lightweight concrete, which allow to build objects with arbitrary layout. They serve primarily as supporting masonry for residential buildings and filling masonry for large-sized halls, for construction of fences and walls.
  • Use of dry-masonry shaped blocks allows to expedite the construction and makes it simple.
  • Basic elements of the system are the basic full-sized block and half-sized block. The blocks are laid to the wall without any binder or joint filler both in horizontal and vertical joints. Fixing of individual blocks in the wall and reinforcement of the wall as a whole is ensured by locks acting in all horizontal joint areas of separate blocks layers.
  • the locks form extensions having the shape of coaxial cylinder on the bottom face of the block. These extensions fit in runners with corresponding shape and size on the upper face of the block at the edge of circular holes made in the block body.
  • Blocks with this design cannot be laid arbitrarily on the lower layer of blocks, they can be laid always with given rotation only. These blocks solve neither interconnection of separating walls, nor installation of infrastructure. If the extension on one block breaks, the consistency of the whole wall is compromised.
  • Another type of dry-masonry block - KB Blok - has pressed-in groove in the longitudinal axis of the block on its upper face. A tongue in the longitudinal axis of the block on its bottom face fits in this groove.
  • This design of blocks does not allow for universal orientation of blocks in the upper layer in the wall against blocks laid in the lower layer. These blocks solve neither interconnection of separating walls, nor installation of infrastructure. If the extension on one block breaks, the consistency of the whole wall is compromised.
  • This system is formed by three basic types of blocks. Two types are equipped with vertical self-locking grooves only on the shorter opposite side faces of the block.
  • One basic type of block is twice as long as the second basic type and features an internal groove located in the centre of the upper surface of the block. Depth of this groove reaches to one half of the block height and a lock is inserted into this groove, which exceeds by half of its height above the basic block. Walls alignment on their edges is provided by the second basic block type with identical width and half length compared to the first basic block with vertical self-locking grooves along the full height of the block located on two opposite side faces of the block. Within the row, this block is not anchored by the vertical lock.
  • the system is formed by four basic types of blocks with vertical self-locking grooves along the full height of the block located on the shorter side faces.
  • the system uses one type of lock. Blocks in the row are connected by the lock horizontally.
  • the lock has the same height as the block. Since the basic blocks for building the walls are equipped with vertical self-locking grooves only on the shorter opposite side faces of the blocks, it is not possible to ensure during the construction that the wall will be perfectly in plane.
  • the system uses keys on the upper face of blocks and corresponding recesses on the bottom face of blocks. These keys and recesses also serve to ensure the planeness of the wall being built.
  • the upper face of the block has a groove along the whole length of the block.
  • the groove is also made in the longitudinal axis of the upper area of the key.
  • This groove receives a reinforcing rod, which protects the inserted key against vertical movements and mainly it serves for T-connection of walls or to connect special corner blocks to the wall. Such connection of walls in corners or T-connections is not sufficient. Therefore the wall consistency is solved by filling the reinforce concrete to internal vertical channels created within the blocks.
  • the system is similar to permanent framework system with defined distance for the filling from the reinforced concrete.
  • Grooves on the wall sides alone cannot have any significance for the wall consistency, also they cannot ensure that the connected walls will be perfectly in plane. Connection of the wall to the corner is provided by the derived block with square-shaped layout having two vertical self-locking grooves on two neighbouring side faces of the block. Therefore the wall corner cannot be bound by the blocks of the system.
  • the patent US 3292331 describes a system formed by the basic type of block.
  • the block is equipped with vertical self-locking T-shaped grooves on the shorter opposite side faces of the block and it has an internal cylindrical groove located in the centre of the upper surface of the block along the full height of the block.
  • the system uses two types of locks.
  • the first type is a self-locking lock for horizontal connection of blocks laid side-by-side.
  • the second type is a cylindrical threaded lock, which vertically connects the blocks laid in rows one above another.
  • the system does not allow binding of the blocks and does not ensure the planeness of the wall. These blocks allow to build walls only with one given width.
  • the patent US 6189282 describes the system formed by three basic types of blocks.
  • One type of blocks is equipped with two vertical narrow self-locking grooves along the full height of the block located on the shorter opposite side faces.
  • the second type of blocks is further equipped with a pair of internal grooves located in the centre of the upper surface of the block along the full height of the block.
  • This type of blocks allows to bind the blocks in rows one above the other.
  • the first type of blocks does not allow to bind the blocks in rows one above the other and can also serve to end the wall.
  • the system uses single type of lock.
  • connection of the wall to the corner or for T-shaped connection serves the third basic block with rectangular-shaped layout with two pairs of vertical self-locking grooves on two opposite shorter side faces of the block, one pair of internal grooves placed in the centre of the upper surface of the block and with another pair of vertical grooves located on one of the longer side faces along the full height of the block and offset to one half of this longer side.
  • the blocks in the row are horizontally and vertically bound always by means of a pair of narrow locks inserted in each side, or centre of the block respectively, via the coursing joint up to the half height of the upper blocks.
  • Such connection provides for certain planeness of walls but it does ensure sufficient strength of the blocks binding in all directions. Therefore this system is preferably designed to use reinforced concrete to armour the wall structure filled in the massive two centreed holes along the full height of the block.
  • This system contains two basic blocks and two derived blocks with a rectangular block shape of the same height ( b ).
  • the first basic block with a square - shaped base has in one pair of the opposite vertical faces always one external groove and the second basic block with a rectangular shaped base and derived blocks with a rectangular-shaped base have in their shorter side opposite vertical faces always also one external groove.
  • These external grooves are made along the full height of the above-mentioned block s and they are created symmetrically around the symmetry plane protruding through the vertical axis of the opposite vertical face s, in which external grooves are located .
  • each external groove in the plane parallel with the vertical face surface, in which it is created is greater than its width ( d ) in the plane of such side vertical face surface.
  • Derived blocks have at their centre an internal groove for tight insertion of internal connecting bars to create a self-locking connection, this groove is created symmetrically around the symmetry plane protruding through vertical axis of the shorter opposite vertical faces and corresponds by its shape and size to the connection of the external grooves of any two blocks from the set of basic blocks and/or derived blocks, which are intended to be laid side-by-side in a row.
  • the principle of the invention is that the first basic block has a square-shaped base with the width (a) and it is equipped on one and/or the other vertical face of the second pair of the opposite side vertical faces with one external groove created along its full height ( b ) , symmetrically around the symmetry plane protruding through the vertical axis of the opposite vertical face s, in which external grooves are located .
  • the first derived block derived from the first basic block has a rectangular-shaped base with the width (a) and length (2a). Internal groove in the centre of the base of the first derived block is created along the full height (b).
  • the first derived block is equipped along its full height ( b ) with minimum two and maximum six external grooves.
  • each its shorter side vertical face symmetrically around the symmetry plane protruding through the vertical axis of the opposite shorter side vertical face s, in which external grooves are located is created maximum one external groove and in each longer vertical faces are maximum two external grooves created symmetrically around the symmetry planes parallel with the shorter vertical faces.
  • External grooves are located in the distance (a/2) from the shorter vertical faces and the symmetry planes are distanced from each other at the width (a).
  • the second basic block has a rectangular-shaped base with the length (a) and width (c) shorter than (a) and it is equipped on one and/or the other longer vertical face with one external groove.
  • This external groove is created along the full height ( b ) of the second basic block symmetrically around the symmetry plane protruding through the vertical axis of the opposite longer vertical faces, in which external grooves are located.
  • the second derived block derived from the second basic block has a rectangular-shaped base with the length (2a) and width (c) shorter than (a). Internal groove in the centre of its base is created along its full height ( b ). This second derived block is equipped along its full height ( b ) with minimum two and maximum six external grooves.
  • each shorter sides vertical face symmetrically around the symmetry plane protruding through the vertical axis of the opposite shorter vertical faces , in which external grooves are located is created maximum one external groove and in each of the longer sides vertical faces are maximum two external grooves created symmetrically around the symmetry planes parallel with the shorter vertical faces .
  • External grooves in the longer vertical faces are located in the distance (a/2) from the shorter vertical faces, while the symmetry planes are distanced from each other at the width (a).
  • the system also includes external connecting bars intended to be tightly inserted into the external grooves and internal connecting bars intended to be tightly inserted into the internal grooves to create a self-locking connection of side-by-side or one on top of the other laid blocks.
  • Blocks are positioned mutually in such a way that the external grooves and the internal grooves of neighbouring blocks follow each other dimensionally in vertical symmetry planes dividing the widths (d), or widths (dd) respectively, of the external or internal grooves cross-sections into halves. This results in a firm spatial binding during construction . In addition, this automatically ensures perpendicularity and planeness of walls against the base and also the right angles formed by cornered walls are maintained.
  • the external and internal connecting bars which are to be used in two lowest rows and two uppermost rows of the wall, have the height (x+1/2)b where x is an integer positive number including zero.
  • External and internal connecting bars to be used in other rows have the height yb where y is integer positive number.
  • all the external grooves do not need to have the same shape and dimensions. It is thus possible that at least one external groove has different dimensions and/or different shape than the remaining external grooves. Sufficient condition for correct usage of such blocks is that both the external and internal grooves following up one another vertically in the wall have identical shape and identical dimensions.
  • Internal connecting bar intended to bind two external grooves attached to each other and made with different dimensions and cross-sections is at any of its cross-section symmetrical around one axis only.
  • the basis of the new solution is the principle of a self-locking connection of construction elements, blocks, in the wall by means of the system of grooves and connecting bars inserted into them in such a way that the ends of the connecting bars are placed elsewhere than on the bottom or upper edge of blocks respectively.
  • the blocks are firmly fixed in space in all three axes. This forms superior mutual connection of blocks in space via multiple connecting surfaces and also it ensures dimensional and angular precision of built walls. Superior connection of blocks within the wall is ensured by suitable shapes of the grooves and their suitable location on the blocks used.
  • For the system of connecting the blocks by grooves and connecting bars is not substantial, of what material the grooved blocks and connecting bars are specifically made.
  • Both basic and derived blocks are characterized by their layout dimensions and precisely defined locations and number of vertical self-locking external grooves on the block vertical faces and the internal grooves in the centre of the block and by exploiting of two types of vertical connecting bars, mostly with the height determined by the double height of the blocks, to form both the horizontal binding of the blocks laid side-by-side in the row as well as the vertical connection of the blocks in rows above each other.
  • Advantage of the solution is the spatial versatility of the blocks, which during construction can be used with rotation by ⁇ 90 degrees around their vertical axis or also with rotation by 180 degrees around their horizontal axis .
  • the basic and derived blocks allow to build walls with widths determined by the multiple of the basic block width. Therefore it is possible to build the lower part of a building with wall thickness for example 3x the block width, mid-floors can follow with wall thickness 2x the block width and walls in the upper floors can be thick only at the single block width. Thus, the structures are not overloaded, material is saved and the system is therefore more environmentally friendly.
  • External vertical grooves may be used for finishing both the outer and inner sides of the wall by means of front panels mounted directly to these grooves.

  • Cross-section of the internal connecting bar 22 is smaller than the cross-section of the internal groove 11 and a self-locking condition applies here, which says that at a given cross-section on each side from the axis protruding through the width dd exists at least one width ff parallel with the width dd , which is greater than the width dd .
  • the system contains the external connecting bars 2 and internal connecting bars 22 .
  • each external connecting bar 2 fig. 5 , 13 , applies that it is characterized by the fact that at any identical cross-section perpendicular to the vertical symmetry plane at least one internal width f of such cross-section of the external connecting bar 2 given by the connecting line of the cross-section sides is longer than the width d of this cross-section of the external groove 1 in the vertical face of the block 3 , 4 , 5 , 6 and at the same cross-section simultaneously for these widths f applies that they are parallel with the width d of the cross-section of the external groove 1 .
  • each internal connecting bar 22 applies that its shape and cross-section is derived from the shape and cross-section of two external connecting bars 2 put side-by-side in such a way that cross-sections of both external connecting bars 2 made as one unit have common widths g , while the widths g do not need to be equal.
  • Cross-section of the internal connecting bar 22 is symmetrical around the axis o dividing the width gg formed by common widths g in halves, fig. 14,15 .
  • the height of external connecting bars 2 and internal connecting bars 22 is such that in no case the two neighbouring external connecting bars 2 or the two internal connecting bars 22 meet in the integer multiple of the block 3 , 4 , 5 , 6 height b , it means that the connecting bars do not end and start in the gap between two blocks 3 , 4 , 5 , 6 laid one on top of the other.
  • External connecting bars 2 and internal connecting bars 22 may be made of various materials, such that concrete, lightweight concrete, porous concrete, steel-fibre-reinforced concrete, iron, plastic, composite material, wood, hardened rubber, etc., while the only condition for selection of the material is its suitable strength and compatibility with the material used for making the blocks 3 , 4 , 5 , 6 .
  • Blocks 3 , 4 , 5 , 6 are positioned mutually in such a way that the external grooves 1 and the internal grooves 11 of neighbouring blocks follow each other dimensionally in vertical symmetry planes dividing the widths d , or widths dd respectively, of the grooves cross-sections into halves. This results in a firm spatial binding during construction. In addition, this automatically ensures perpendicularity and planeness of walls against the base and also the right angles formed by cornered walls are maintained.
  • Such principle of construction ensures that the wall is firmly anchored in all three axes in the space.
  • the derived blocks 4 , 6 are gradually bound, it means that each horizontal row of blocks 4 , 6 is offset against the preceding one by a step joint with the width a .
  • the rows of the first derived blocks 4 , or the second derived blocks 6 respectively are offset in the wall against the preceding and subsequent rows by the distance corresponding to the width a .
  • the bottom row of the first derived blocks 4 is laid by their longer side in direction of building process and the upper row of the first derived blocks 4 is laid by their shorter side in direction of building process.
  • the first derived blocks 4 are mutually bound in the wall body.
  • Space formed between the sides of the external groove 1 and sides of the external connecting bar 2 , or the sides of the internal groove 11 and sides of the internal connecting bar 22 respectively, can be preferably filled either in full or only partially with sealing material, such as polyurethane foam, cement mixture, chemical anchor, etc., or with any kind of glue.
  • sealing material such as polyurethane foam, cement mixture, chemical anchor, etc., or with any kind of glue.
  • the blocks 3 , 4 , 5 , 6 are manufactured by casting the material to moulds or by vibrating and pressing the material into dies, it is preferable to use the external grooves 1 and internal grooves 11 slanted regularly in full height b with standard bevel. Conically-shaped external grooves 1 and internal grooves 11 will allow for easier and non-destructive release and demoulding of blocks 3 , 4 , 5 , 6 from the form.
  • Some external grooves 1 on the wall face may be used with advantage for connecting and anchoring of other perpendicular elements, such as another wall attached to the existing wall, by means of internal connecting bars 22 .
  • the internal connecting bars 22 can be used in some external grooves 1 to fix the window frames and door frames in the construction openings, or they can be exploited for distribution of utility lines - water mains piping, heating system piping, electrical power supply cabling and also data networks cabling. In such cases no external connecting bar 2 is inserted into the external groove 1 .
  • Modular system for precise construction may be used anywhere during building process both for residential as well as industrial objects instead of current walling and construction systems.
  • the presented system provides the option to build supporting walls and separating walls, including integration of the window and door frames immediately when a storey is being built, it also allows from the major part to integrate the utility lines networks including cabling without the need to mechanically break already built walls. From the outer side, it allows easy installation of insulation systems and surface finish decors. Owing to described characteristics the modular system for precise construction in contrary to existing building systems allows to achieve a significant savings of both the time and costs. During realization of the building the system for precise construction minimizes demands for using the jointing materials.
  • the connecting bars are made of suitable material and if the blocks are made with sufficient accuracy, it is possible to consider purely dry walling. Otherwise, it is suitable to seal the gaps with material either fully or partially filling the space between the sides of grooves and sides of the connecting bars.
