Description

WITHTHEBUILDINGBLOCK
The present invention relates to a building block for erecting walls and like structures, whereat a plu¬ rality of such blocks are laid in courses one upon the other . There is a need within the building industry for new building elements which can be handled as readily as conventional building stones and which are as flexible in use as said stones, but which permit more rational building methods to be applied. The use of conventional building stones for erecting walls requires the applica¬ tion of a number of time consuming working operations. Among other things, the individual stones or bricks must be bonded together with mortar, which is time-consuming and requires a high degree of expertise if a good result is to be achieved.
The Swedish Patent specification 352 914 describes a building block of the so-called hollow type, in which part of each side piece of the block is offset vertically through a small distance to form outwardly projecting mounting flanges on one bearing surface of the block and a corresponding groove on the other. Such blocks enable a wall to be built without the use of mortar, but re¬ quire separate insert pieces at corners, and at window openings and the like. Further, this kind of -block has no means which prevent relative displacement of the blocks in the long direction thereof.
The Swedish Patent specification No. 7410741-8 also describes a type of building block which requires no mor¬ tar when erecting a wall etc. The two bearing surfaces of the block accordin to this Swedish patent specification are corrugated in two directions mutually at right angles to one another, which facilitates the building of corner assemblies and which holds the blocks against movement both in the longitudinal and in the transverse directions. This fixing of the blocks, however, cannot be achieved with absolute accuracy, and further the blocks must be manufactured with a high degree of precision.
The main object of the present invention is thus to provide a building block of the kind described in the in¬ troduction, which can be laid without the use of mortar, which permits simple corner assemblies to be made, and which can readily be fixed in precisely defined positions relative to one another } and which can also be manufactur¬ ed in a relatively, simple fashion with a high degree of precision. The main object of the present invention is thus to provide a building block of the kind described in the in¬ troduction, which can be laid without the use of mortar, which permits simple corner assemblies to be made, and which can readily be fixed in precisely defined positions relative to one another, and which can also be manufactur¬ ed in a relatively simple fashion with a high degree of precision. ' •
To this end, the building block according to the in¬ vention is provided with two mutually opposing bearing surfaces, of which one is provided with guiding projec¬ tions and the other with recesses arranged, when laying the blocks in straight courses, to receive the projections of an overlying or an underlying block.
In accordance with the invention, mutually adjacent blocks are connected and fixed in position by means of ties, to which end said other bearing surface of the block is provided with transversely extending groove-like recesses for receiving said ties, the recesses of one block being so shaped as to be able also to receive the projections of an overlying or an underlying block in a course which forms a right angle with the course in which the first-mentioned block is laid. Thus, this enables the blocks of -different courses to overlap each other and to form corner joints. Preferably, the transversely extending, groove- shaped recesses extend from the lateral defining surfaces of the block into a central opening in said block and also down into said opening, conveniently over the full height of the block. This enables the use of extremely simple and effective forms of ties. In a preferred embodiment of the invention the block includes two side pieces connected together by means of transversely extending partition walls, whereat the guid¬ ing projections comprise ridge formations along the edges of each partition wall at one bearing surface of the block defining said side pieces, while the partition walls at the other bearing surface of said block are provided with recesses corresponding to said ridges. Preferably, said ridge formations and the groove-shaped recesses have a substantially triangular cross-sectional shape and the partition walls at said other bearing surface of the block are provided with wedge-shaped recesses with flank angles corresponding to the flank angles of the ridge formations.
A block-laying tie for use together with building blocks according to the invention comprises a rod-like main part connected at each end with at least one trans¬ versely extending engaging rod. For the purpose of fixing blocks provided with central openings in a single wall, the distance between the two transversely extending engage¬ ment rods should correspond substantially to the width of the central openings of the block. In the case of ties intended for use in a double or cavity wall, the rod-like main part is suitably provided with two transversely ex¬ tending engagement rods at each end thereof, whereat the distance between said engagement rods of each pair corre- sponds substantially to the distance between the side de¬ fining surfaces of the block and the central openings, while the distance between the two inner engagement rods of each pair corresponds to the desired distance between the two walls forming said cavity wall. The invention will now be described in more detail with reference to the accompanying drawings. Figure 1 is a perspective view of a building block according to the invention illustrating one bearing sur¬ face of said block.
Figure 2 is a perspective view corresponding to Figure 1 illustrating the other, bearing surface of the block located opposite the bearing surface shown in Figure 1.
Figure 3 illustrates a tie for single walls.
Figure 4 is a tie for double walls.
Figure 5 illustrates the manner in which the blocks of a single wall are mutually fixed.
Figure 6 illustrates a corner- of a double wall built of 'blocks according to the invention.
Figure 7 is a sectional view of the outer part of an outer wall with wall facade elements mounted thereon. The building block illustrated in Figures 1 and 2 includes two side pieces 1 and 2 connected together by means of transverse partition walls 3. The upper bearing surface of the block is provided with ridge-like projec¬ tions 4 arranged along the edges of each partition wall 3 adjacent the side pieces 1 and 2. The partition walls are provided on the opposite bearing surface of the block with wedge-shaped recesses 5 having inclined flank sur¬ faces. The angle of inclination of said surfaces corre¬ sponds substantially to the angle, of the flank surfaces of the ridges 4, thereby to provide accurate lateral fixation between two mutually adjacent blocks.
In order to permit blocks to be laid in layers which form right angles to each other, the lower bearing surface of respective blocks is provided with transverse groove-shaped recesses 6 which are arranged in pairs at a distance apart which corresponds to the distance bet¬ ween each pair of ridges 4 on the opposite bearing sur¬ face of said blocks. These groove-shaped recesses also fulfil other important functions, v/hich will be described hereinafter. The number and cross-sectional shape of the projections 4 and grooves 6 may be varied as desired, although, as will be understood, the shape and position of the projections and grooves must be adapted to one an¬ other. Thus, the two projections 4 may, for example, be replaced with a single projection, suitably located along the centre line of the block. In the illustrated embodi¬ ment, the blocks are each provided with a large V-shaped recess 5. As will be understood, this may be replaced with two groove-shaped recesses corresponding to the rid¬ ges 4. The large recess 5, however,, enables electrical lines and pipe lines to be readily drawn through a wall built of blocks constriucted according to the invention.
Thus, the only essential feature is that both the reces- i ses 5 and the grooves 6 enable accommodation of the oro- jections 4 while provi !ding good guidance of the blocks relative to one another.
For the purpose of preventing alternate blocks from being displaced relative to one another longitudinally, the grooves 6 are extended at one end thereof with grooves
7 which extend vertically down into the openings formed in the blocks between the partition v/alls 3. When build¬ ing a single v/all this enables ties according to Figure
3 to be used, said ties comprising a rod-like main part
8 provided with tv/o transversely extending engagement rods 9. In this case, the distance between the engagement rods 9 corresponds to the v/idth of the central opening through the block. The laterally projecting parts of the rod-like main part 8 are received in the grooves 6 of adjacent blocks, v/hile the transverse engagement rods 9 are received in the grooves 7 of two blocks located one upon the other. The use of the ties illustrated in Figure 3 is shov/n more clearly in Figure 5, whereat the indivi¬ dual blocks are identified by the reference 12. It will be seen from this figure that the blocks 12 are posi¬ tively fixed relative to one another when the ties illu- strated in Figure 3 are inserted in the grooves 7.
The tie or dog clip illustrated in Figure 4 com- prises an elongate rod-shaped main part 10 provided at each end thereof with a pair of gripping or engaging rods 11. In the illustrated embodimemt the distance bet¬ ween the engagement rods 11 of each pair conforms to the thickness of the side pieces of the block, enabling the blocks of two mutually parallel walls to be fixed to¬ gether, at the same time as the blocks in said tv/o walls are held at a determined distance apart corresponding to the distance betv/een the inner engagement rods 11 of each pair. Alternatively, the two engagement rods 11 of each pair, similar to the rods 9 of Figure 3, may be arranged to be moved down into the cenntral openings of the blocks.
Figure 6 illustrates the manner in which a corner of a double cavity v/all can be constructed when using the blocks illustrated in Figures 1 and 2, mutually bonded by means of the ties illustrated in Figure 4. Two single walls 13 and 14 are built from the blocks 12, between which walls an insulation 15 is arranged. The insulation 15 may comprise conventional insulating slabs, but pre¬ ferably comprises a foamed plastics material introduced into the space between the walls 13 and 14, said insula¬ tion being introduced into said cavity subsequent to erecting the whole of said cavity wall or subsequent to erecting a substantial part thereof. The blocks 12 laid in line with each other are guided laterally, inter alia, by the co-action between the projections 4 and the re¬ cesses 5. In the corners of the wall structure v/here the blocks form an angle with each other, the projections 4 are received in the grooves 6 in the lower bearing sur¬ faces of the blocks.
For the purpose of preventing longitudinal movement between blocks of different courses, and for the purpose of fixing the two walls at a given distance apart, ties or dog clips according to Figure 4 are arranged between the blocks of the two walls. In this case, the pairs of engagement rods 11 are pressed down over the inner side pieces of mutually opposing blocks, whereat the outer en¬ gagement rods 11 are received in grooves 7 and the longi¬ tudinal rod 10 is received in grooves 6. When laying the next course, the upper parts of the engagement rods 11 will embrace the inner side piece of an overlying block, v/hereat the outer engagement rod 11 of each pair is re¬ ceived in one vertical groove 7 of said block. In this way there is obtained a positive fixation of blocks lo- cated one upon the other against relative movement, while bonding the two single v/alls together in a reliable man¬ ner. The ties are suitably made of an acid-resistant ma¬ terial .
Figure 7 illustrates the use of a third kind of tie, comprising a rod-like main part 16 and an engagement rod 17 arranged at each end of said main part. This tie is intended for suspending a facade element 18 on an outer v/all , v/hereat the distance between the engagement rod 17 corresponds to the thickness of the outer side piece of the block 12 plus the distance from the inner surface of the facade element to a groove or hole 19 in said ele¬ ment intended for accommodating the engagement rod 17. The illustrated embodiment of the facade element 18 is only a preferred example, v/hich may be modified in se- veral respects, both with regard to the outwardly visib¬ le surface and with regard to those parts of the element by v/hich they are suspended and through which they over¬ lap each other.
The building blocks according to the invention can be manufactured by casting said blocks in moulds provid¬ ed v/ith insert plates having a form v/hich corresponds to the lower bearing surface of the blocks. The upper bear¬ ing surface of the blocks is formed with the aid of a roller having a profiled surface corresponding to the upper bearing surface of said blocks, said surface being formed by relative movement of the block and roller in the longitudinal direction of the block.
Although the invention has been described and illu¬ strated with respect to a preferred embodiment thereof, the embodiment is not limited to the invention but can be modified within the scope of the following claims, whereat a common feature of all embodiments of the in¬ vention is that the blocks shall exhibit transversely extending recesses which, in addition to receiving the ties can also be used for receiving guiding projections when building corners αr when connecting intermediate walls to an outer wall .i i
