Bricks of similar type with rudimentary female and male slots in their vertical lines are well known. But this bricks do not work as structural breaks, but as rudimentary supplementary breaks or dependant by other materials.

Other known types of bricks are connected with female and male cylindrical slots, with slots suitable for iron bars, concrete etc.

Bricks with horizontal and vertical connection king-slots are fitted completely articulately with one another, but with the floor base and the roof, creating a uniform whole in the sense of a puzzle.

The advantages of this invention are many in comparison to the existing building systems. The use of the bricks system, with horizontal and vertical connective king- slots has many advantages as far as the following : 1.-It offers new building possibilities, for easy and quick construction.

2.-It offers a uniform and absolute construction coherence which makes the building aseismic.

3. -Due to the perfect connection of the bricks with bonding materials, the contractor is saved from plaster and only stucco is needed. <BR> <BR> <P>4. -The construction work is more clean.<BR> <P>5. -The time required to complete the work is very little.

6.-It contributes to the economy of the labour and the material and as a result the total cost of the construction is much smaller.

The bricks of the present invention have the following categories: A.-Bricks for vertical construction, flat and concave.

B.-Roof, window and door bricks and window and door bricks.

C. -Bricks for floor and roof support.

D.-Final roof bricks.

The flat as weil as the vertical construction bricks have the following categories: A1.-Oblong bricks Figures 1,2, 3,4, 5,6, 20,20A, 21, 21A, 21B, 21C, 32,33, 38,39, 40,41, 43 and 44.

The oblong bricks are made of three parallel rectangular parallelepipeds, Fig. 5 and 6, in their large side and adjacent two by two between them, with the middle one in parallel lifted against the others in a distance equal, smaller or greater than their smaller side thus creating a female king-recess in its lower part and a male king- prominence in its upper part.

The upper middle, parallel lifted parallelepiped with its horizontal position and its length gives the following brick types: 1.-Oblong bricks closed on both ends. Fig. 32 and 38 2.-Oblong bricks closed on one end and with a male king-prominence on the other end. Fig. 20 and 20A

3.-Oblong bricks with a female king-recess on one end and with a male king- prominence on the other end. Fig. 1,2, 3,4.

When these are glued with one another they form the finish of the connection with the roof.

The upper part of these pieces is cut according to the height of each level.

Bricks D1, D2, D3, D43 and D5, can be made of argil, concrete, wood, glass, as well from material or combination of materials which are known or will be made known in the future.

CONSTRUCTION OF THE MASONRY A.-Construction only with bricks After the construction of the uniform base where the building will be supported, wooden, metal or concrete king-piles are placed on this, according to the architectural plan of the building, on top of which the bricks will be glued with strong glue on their lower feminine side.

The king-piles will be placed double in the event of double masonry.

The bricks must be placed in their first row, according to their shape, the straight ones for the current metres, the angles on the corners etc.

From the second row onwards the bricks must be placed in such a way in order to be crossed between them. This process will continue until the height of the base of the first floor minus one row of bricks. In the next row the bricks for the floor support will be placed. Then, the building is completed until the height of the roof.

The placement of the roof is made with roof bricks ; the wood for the attic is placed on top or that of the upper ceiling and the wooden roof slab, slab or any other material.

Fig. 72,73, 78,79 and 80. The base and the height of the corner and scalariformed roof bricks can set the inclination of the roof angle.

Therefore, according to the length 3a a top angle of 143 and 8'degrees if formed.

According to length 2a a top angle of 126 and 52'degrees is formed and even 90 degrees.

In the first and second case the height is equal to a+x.

In the third case of the 90 degrees the height is equal to 2a+x.

Based on these three cases the inclination of the straight roof bricks is set respectively as follows : 18 degrees 26' 26 degrees 34' and 45 degrees and 0', Fig. 78,79 and 80.

For the creation of windows we place the roof bricks for doors and windows and we continue they assembly onwards.

In a similar manner to the above we place the cylindrical walls as well as the arches.

B. -Construction on a concrete frame.

The construction requires besides the lower king-pile, also vertical ones on the sides of the pillars as well as on the roof Fig. 45. These king-piles must be evened and co- planar. The building method is the same. The only difference may be in the case where the opening between the pillars or the walls does not have the same distance according to the sum of the length of the bricks. In this case, simple oblong pieces of supplements of different sizes can be used. In the finish of the roof the segmented brick can be used, which can be adjusted in the dimensions of the height of the construction with the method of cutting tiles.

Decorative bricks In the event the bricks'external surface are embossed Fig. 41, they can give the impression of a stone masonry or other decoration.

Bricks with horizontal and vertical connective king-slots can be solid or have in their parallelepipeds, holes in different shapes with a section of known geometrical shapes; for example, circle, square, parallelepiped, rhomb, polygon etc. Fig. 81,82 and 83.

Combined bricks with horizontal and vertical king-slots can be used: 1.-As a complete set of construction materials for buildings, offices, factories, gardens and fencing etc. <BR> <BR> <P>2. -As a material of internal and external masonry.<BR> <P>3. -As a material for decorative works.<BR> <P>4. -As a material for constructions of any nature.
