Definitions
- a building block The invention relates to a building block of the kind which is intended to form part of a vertical wall, a vertical facade or like building structure, and which is bonded to neighbouring building blocks by means of horizontal bed joints and vertical heading joints, and which building block has a channel-like recess, open at both ends thereof, formed in at least one end surface thereof bordering a heading joint.
- the mortar When building a masonry wall or like structure from building blocks and mortar, the mortar is normally applied manually with the aid of a trowel to that end surface, or header face, of the block which borders a heading joint, and the block is then positioned on the mortar in the bed joint and pushed into position against the end surface of a previously laid block. A satisfac ⁇ tory heading joint is normally obtained, provided that the mortar has been correctly applied.
- the task of apply ⁇ ing mortar is relatively time consuming and therewith expensive.
- a prime object of the invention is therefore to provide a building block of the aforesaid kind which will enable the use of a pipeable jointing material, hereinafter referred to as mortar, and which eliminates totally, or at least substantially, the risk of excessive- ly large quantities of mortar exiting from the rear side of, for example, a building facade.
- Figure 1 illustrates a conventional building block bonded to a further conventional building block by means of a heading joint
- Figure 2 is a sectional view taken on the line
- Figure 3 illustrates a building block accord ⁇ ing to the invention and the heading joint formed with an adjacent block
- Figure 4 illustrates a modified building block according to the invention, seen in the direction of the heading joint
- Figure 5 is a view taken on the line V-V in Figure 4.
- Figure 1 illustrates a conventional building block 1 made, for example, of burned clay, and a further, identical building block 2.
- Each of the conventional building blocks has on one end-surface thereof a channel- shaped recess 6, which is open at both ends and which is intended to extend vertically.
- the blocks 1 and 2 When building a facade or like structure with building blocks and mortar, the blocks 1 and 2 are placed in spaced relationship to form visible joints and then pressed into the mortar of a bed joint 8 provided on underlying blocks 7 ( Figure 2) .
- mortar will be forced up into the recess 6, as illust ⁇ rated in Figure 2, and when mortar under pressure is piped down into the recess, which is completely symmetri ⁇ cal in sectioa between the surface 10 of the facade and the rear side 11 of the masonry, mortar will be forced from the recess to form strings or beads of mortar 4 and 5, of which the string 5 is scraped away.
- the bot ⁇ tom edge 5' of the string 5 will reach the mortar in the bed joint 8 earlier than central part 12 of the piped mortar, which also applies to the rear side, where the bottom edge 4 1 of the string 4 reaches the bed joint 8 more quickly than does the central part 12.
- the main reason for this is because the frictional resistance experienced by the inflowing mortar, which is applied substantially centrally of the recesses 6 located bet- ween the blocks 1 and 2 resting on the bed joint 8, is substantially equally as great towards the rear side 11 as towards the facade side 10, and because the readily flowable mortar is deflected downwards at the edge parts 6' of respective recesses. This results in an air-in- elusion 9, which can only be removed by injecting a large surplus of mortar, with the associated disadvan ⁇ tages mentioned in the introduction and, naturally, causing excessive mortar losses.
- the wall surface of the recess 6 is formed so that the frictional resistance is much greater in a direction towards the rear side 11 than towards the facade side or the front side 10, therewith ensuring that the head- ing joint is completely filled with mortar in a direction towards the front side 10 before the joint gap towards the rear side 11 is fille ⁇ and mortar begins to exude, or in all events such that only a negligible amount of mortar exudes on the rear side subsequent to visually establishing that the joint is completely filled on the facade side.
- Such a gap 15 forms a barrier which is effec ⁇ tive to prevent water penetrating through rearwardly lying insulation.
- Figure 3 there is illustrated an embodiment of a recess 17, the wall of which is smooth ⁇ ly curved and presents a wall portion 18 of a smaller radius of curvature than the remaining wall portion 19 connecting with or terminating at the front side 10 of the structure.
- the respective rear side-surfaces 20 and 21 of the illustrated blocks 13 and 14 can be made slightly longer than the respective front side-surfaces 22 and 23, wherewith the free joint gaps on the rear side 11 of the structure will be narrower than the joint gaps on the front side thereof, or in extreme cases will be totally eliminated.
- Figures 4 and 5 illustrate a modified recess of * ⁇ which the rear part 24 which produces a high degree of friction is provided with vertical cams or ridges 25, 26,. 27 while the wall part 29 which faces the front side of the structure is smooth and creates but small friction, i.e. a low pressure drop.
- the two portions 24 , 28 of the recess wall may have mutual- ly the same radius of curvature, although the radius of the wall portion 24 is preferably smaller than that of the wall portion 28.
