Abstract

The invention relates to a system for coupling bricks, of the type used in the construction of dwellings in general. According to the invention, the system comprises at least one brick having a main face and a secondary face opposite the main face, the main face including perpendicular projections and the secondary face including cavities that are axially aligned with the projections.

Description

Object of the invention

This invention refers to a brick coupling system of the type used in the construction of dwellings, which yields important savings in the building of the walls and permits at the same time to obtain better thermal coefficients.

Background of the invention

As is well known, for masonry works (usually designated as masonry) mainly stone materials are used, such as: clay bricks, cement mortar blocks, stone and other materials of the same or similar origin to those mentioned. The bricks are used in the building of closing walls, façades and partition walls. They are preferably used to build walls or separating walls. Although they may be assembled without any binding product, usually they are bound with a mortar mass. The arrangement of the bricks in the wall is called brick layout and a wide variety of forms of bricks layout are known in this field. In the construction industry, under the name mortar, it is to be understood a combination of binding materials and agglomerates formed by cement, fine aggregates and water. Generally, mortar is used in masonry works as binding material, coating for walls, etc.
The traditional binding between bricks for a non supporting wall is based on the application of mortar on all the surfaces of contact of the bricks. This mass of cement is much more heat conducting than the same bricks, thus generating a thermal bridge through said mass between the internal coating and the external coating of the wall which are at different temperatures. For this reason, the desired insulating effect is substantially reduced, with the subsequent detriment to energy conservation. All of this generates pathologies in the internal coating such as cracks, changes in the colour of the wall in the area of the joints, and even the spreading of fungus.
On the other side, the tendencies and potential rules for building in different weather areas will favour the saving and conservation of energy. However, until now known, no solutions have been found which permit to optimize the use of mortar as well as to maintain the heat insulation characteristics.

Description of the invention

It is therefore an object of the invention to provide a system for the binding of bricks of the type used for the building of dwellings in general, wherein the system comprises at least one brick having a main face and a secondary face opposite the main face, the main face including perpendicular projections and the secondary face including cavities that are axially aligned with said projections.
For better understanding of the object of the invention, various explanatory figures of drawings have been annexed showing one of the preferred forms of embodiment of the invention, in which:

Figure 2 is a front elevation view of the system of figure 1 as used in the construction field.

Description of a preferred embodiment

According to the figures, the system for joining bricks has been shown with the general reference number 1. Said joining system 1 comprises at least one brick 2 that in this particular embodiment is a brick of the type called thermal brick. The thermal concrete brick is a prefabricated body with the form of a straight prism made out of light aggregates, for its use in the construction of walls. It is made out of light aggregates from volcanic origin which confer higher thermal characteristics than those of the red baked bricks and normal concrete blocks.
Due to the fact that the thermal bricks are manufactured using light aggregates, a final product is obtained that given its light weight, has excellent thermal characteristics as compared to the traditional systems for the construction of walls (blocks and baked bricks). Its main application consists in the construction of walls for dwellings, commercial buildings, etc. in which an objective is to obtain thermal efficiency.
However, all experts in the matter will understand that the reach of the invention is not determined by the type of brick to be used as this may be substituted by any type of brick permitting to apply the characteristics defined in the annexed claims.
As a consequence, the brick 2 has a main face 3 and a secondary face 4 opposite the main face. It is possible to define as well, according to the use to be given to the system of the invention, that the main and secondary faces may be the lower and upper faces respectively or viceversa, depending on the arrangement of the brick 1 at the moment of being applied to the construction. It is to be remarked as well that it is possible to define said faces as male face and female face, due to its embedding together at the moment of application of the system of the present invention.
The main face 3 has perpendicular projections 5 which define a means for the displacement of material. As an additional characteristic, each of the perpendicular projections 5 has a substantially rectangular geometrical shape having in its end portions small widenings 7. These widenings 7 define means for holding the displaced material. On the other side, in said main face or male face 3 some means for delimitation of the displacement will be provided, which means are defined by the lengthwise protrusions 8.
To the secondary face 4 comprises corresponding cavities 6 which define a means for the location of the displaced material.
For better understanding of the subject of the present invention, a description of the use of the brick binding system will be made in reference to the annexed figures of drawings. Thus, at the time of building a wall, as shown in figure 2, the operator will place the brick 1 with its main face directed downwards, so that the whole brick will be immersed within a bed of mortar 9. Said bed of mortar 9 should be sufficiently thick in order that when locating the brick 1 and exerting pressure in the downwards direction, the mortar shifts towards all of the cavities, obtaining in this way a correct binding. Afterwards, the operator will continue the application of mortar within cavities 6 in a flushing manner, taking care that the applied mortar covers all of said cavities 6.
However, when locating the second brick 1, the operator should place the main face 2 opposite to the secondary face 3 of the first brick. After locating one brick on the other and due to the fact that the projections 5 stand out slightly, the same cause the mortar 9 to start displacing entering within the cavities 6, as shown in figure 2. Afterwards, the pressure is continued until both bricks contact each other by its internal faces. Additionally, the lengthwise protrusions 8 maintain the alignment of the wall, preventing the bricks to laterally offset.
In this manner, the mortar 9 shifts towards the cavity 6 in the same volume generated by the projections 5. Is to be remarked that the shape of the projections 5, more precisely its widening 7, permits to obtain the anchoring of the structure when the mortar sets.
The form in which the material has been applied prevents direct contact between the internal and external coatings of the dwelling, improving the thermal characteristics of the joints and making the building of the walls more economical for preventing waste during the application of the mortar, as it usually happens in the constructions according to the state of the art.
