DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a building block of the type comprising: second bearing faces; bearing face to the second; bearing faces respectively; and
A block of known type and indicated above is illustrated, for example, in the Italian Patent Application No. 68558-A/77, corresponding to the U.S. Pat. No. 4,110,949, and is illustrated in FIG. 1 appended to the present description. The use of a plurality of these blocks of known type enables a building structure to be constructed by the superposition of these blocks in the dry state and in staggered rows. These blocks are then connected and positioned by hand or with a tool on sliding couplings in vertical holes in the body of the block such that they are moved axially in respective holes, for a movement equal to approximately half the height of the block, such that they engage half-way in corresponding holes in the underlying block. The transverse grooves and apertures, disposed with vertical axes, together with the longitudinal channels in the block, help to forms grid of intercommunicating vertical and horizontal channels in the resultant building structure. Following the laying of the rows of blocks and their connection by the couplings, concrete is poured into the vertical channels and can thus easily also extend into the horizontal channels, giving rise to the formation of a concrete grid.
A disadvantage of using blocks of known type for producing these building structures is that laying the blocks dry in superposed rows is very laborious, the couplings of the upper blocks having to be centred perfectly with the corresponding holes in the lower blocks. Furthermore, owing to the manufacturing tolerances of the blocks, the resultant building structure has fissures between adjacent blocks which may be very large since the longitudinal position of each single block is determined clearly by the longitudinal and transverse positions of the blocks the underlying row.
The presence of fissures between the blocks is very harmful since they can be infiltrated by water, in particular, which freezes during cold weather and can cause cracks in the building structure or even damage it, thus compromising its integrity, its aesthetic appearance and its mechanical and insulation properties.
SUMMARY OF THE INVENTION
The object of the present invention is to produce a building block of the above-mentioned type which overcomes the above disadvantages and which is in particular simple and economical to use in the production of a building structure, accelerating the construction work and reducing the occurrence and size of fissures between adjacent blocks.
Furthermore, the scope of the present invention is to produce a building block which is simple and economical to manufacture, enabling it to be produced easily on a large scale and a high standard of quality to be attained.
A further object of the present invention is to provide a modular building block for producing building structures which are also complex and maintain good orthogonal characteristics relative to the ground, even for considerable heights, and which have good anti-seismic and solidity characteristics, good characteristics of resistance to atmospheric agents and habitability, and which also have a pleasant aesthetic appearance.
A further object of the present invention is to produce a building block of the above type, of which the use in the production of a building structure involves the production of a grid of channels into which the binder, in particular concrete, can be poured rapidly and easily, such that, when it has solidified, a grid which is as homogeneous and free of empty spaces or bubbles as possible is produced, thus providing maximum anchorage.
In order to achieve the above objects, the subject of the present invention is a building block of the type described above, characterised in that the block reference and positioning means comprise at least one longitudinal seat on the first bearing face and at least one longitudinal projection on the second bearin
