The invention relates to the construction, in particular to the structural members, and is a building block that can be used for walls and foundations, as with a binder, and without them, allowing you to use this building block in the construction of buildings, structures, pavilions, fencing, fences and other pre-fabricated both fixed and collapsible structures in the form of frames, partitions etc. building block can be used in the manufacture of toys and their elements in the form of a toy construction sets, designers and other Building block can be made depending on tasks from any structural materials using traditional production techniques, such as molding, casting, extrusion.
There are many types of building blocks, each of which has different structural characteristics depending on the goal that is reached in a particular case.
For example, well-known building block for masonry walls (see the description of the invention to the patent of Russian Federation №1649058)having longitudinal side walls connected by partitions with the formation of the cavity for placement of structural and/or thermal insulation liner, and the locking tabs. The locking protrusion is made in the form of the speaker is speaking over the side walls of the septum rectangular size, equal to the distance between the inner faces of the lateral longitudinal walls, and the partition offset from the end face of the side wall by a distance equal to one-fourth its length minus the thickness of the septum, while serving part partitions are made excavation, the volume of which is equal to the volume of the fixing protrusion. The disadvantage of this unit is the lack of locking tabs on its longitudinal walls.
Known building block (see the description of the invention to the patent of Russian Federation №2162500), including longitudinal side walls connected by partitions with the formation of the cavity for placement of structural and/or thermal insulation material, and the locking protrusions, wherein the locking protrusion is made in the form of protruding over the side walls of the septum of rectangular cross-section size is equal to the distance between the inner faces of the lateral longitudinal walls, while serving part partitions are made excavation, the volume of which is equal to the volume of the fixing protrusion, and the bulkhead located at a distance from the ends of the side wall equal to one-fourth its length. The disadvantage of this building block is the lack of grip on its longitudinal walls, and the absence of additional reinforcing ribs on the walls.
Known building block (see description of the of the invention to the patent of Russian Federation №2157442), having the form of a parallelepiped representing the six faces, four of which are vertical and two horizontal, including covered and covering elements for interpenetration with tight fit and the imposition of several blocks without cement, mortar or other termination of binder, with covered and covering elements are located on the horizontal faces and made in the form of a continuous longitudinal elevation, placed on the upper horizontal face the entire length of the block, and a continuous longitudinal groove, placed on the bottom face, wherein the near longitudinal relief posted by a continuous longitudinal channel formed is attached to an inclined surface topography steep edge attached to the horizontal bottom, and near the longitudinal groove is placed a continuous longitudinal ledge formed is attached to an inclined surface of the wall with a low slope or no slope, attached to the wall with a large slope or vertical, while the boxes to overlap each other ledge and a channel located opposite each other, form a continuous longitudinal cavity extending the entire length of the block. The disadvantage of this unit is that covered and covering elements made in the form of a continuous food is inogo groove, that provides reliable fixation blocks among themselves only in one transverse relative to the longitudinal faces that direction.
Known building block (see the description of the invention to the patent of Russian Federation №2081264), including parallel one to the other walls, which are interconnected installed perpendicular thereto partitions and made with grooves and corresponding in shape and dimensions of the locking protrusions, wherein the height of the walls is 0.3-1.2 height of the walls, and the distance between the slots and the notches and the distance between the latter and the vertical end faces of the block is less than or greater than the thickness, respectively, partitions and walls in the place of formation of the groove, and a horizontal cross-section of grooves and protrusions has a curved shape or a shape of a regular or irregular polygon, and the grooves have the same or different shapes and sizes, and the distance from the outer vertical faces of the partitions to the end faces of the walls is equal to or more than 0.5 of the thickness of the partitions and is equal to or less than 0.25 length of the walls, and the distance from the transverse plane of symmetry of the walls of the grooves are equal distances from the end faces of the walls of the respective grooves of the protrusions. The disadvantages of this unit is the lack of covering and covered elements, whic is on its top and bottom faces, and the absence of reinforcing ribs on the walls of the block.
Also known building block, called the author of "building block" (see the description of the invention to the patent of Russian Federation №239880). This building block is made with through cavities separated by partitions perpendicular to the longitudinal axis. For its manufacturing of polymer material and reduce weight it is made with located with one of its sides with sockets along its emptiness. The walls of the sockets can be made oblique. But building block, which is the prototype, has drawbacks, the main of which is the lack of additional bundles of blocks interconnected by a method of bonding metals or reinforcing elements, as well as the absence of ribs, which limits the scope of the invention. Also the disadvantage of this unit is that its protruding elements covered by the socket when the connection blocks perform work shift only in one direction - toward their mates with the wall of the funnel.
The goal of the inventors was to create such a building block, which would have increased the stability of the fastening blocks among themselves, and would have increased strength and reliability.
The technical result achieved is m when solving before inventors tasks was more stable bond the blocks together. This is achieved by projecting the elements of the new unit will perform the work shift in all directions, as they mate with the walls covering them interpenetrating holes on all sides. In addition, it is achieved that the design of the new unit provides for a system of holes, through which you can further fasten the blocks of different mounting or reinforcing elements. However, the technical result consists in increasing the strength and reliability of the structure, due to the fact that the walls of the new block and walls reinforced with ribs, and are a Central part thickening.
The essence of the invention lies in the fact that the building block with through cavities separated by partitions perpendicular to the longitudinal axis, made with framing it voids the tabs on the upper end surface and return them penetrating the slots on the bottom end surface, and also contains a system of holes, plugged in its Central part by a partition with a way to fix it for converting plugged in through the walls and partitions of a block is performed with additional ribs and has in its Central part uelsen is, and on the lateral surfaces of the building block are aligned.
Also the invention is that the partition connecting the longitudinal walls of the block to form the through voids square shape.
However, the essence of the invention is that the grooves passing through the lateral surfaces of the new unit is designed in such a way that when combining two blocks walls they form holes round shape.
In addition, the invention consists in that the grooves running along its side surfaces in such a way that when combining two blocks walls they form holes square shape.
