The invention relates to the construction of engineering structures with supporting frame in the form of a prefabricated composite structures with shell, plate, or shell-plate large structure, single and multivariable, including cellular, with mounting blocks of reinforced concrete with steel or non-metallic with rods, possibly with the inclusion of shell and plate plate or thin-walled shell elements made of steel sheet metal and cast metal parts forming the connection of the mounting blocks between themselves and with other designs of constructions, mainly for applications in the fields of construction projects, such as bridge building, bottom and above-ground tunnelling, Foundation construction the construction of containers, creating paintings of Railways and highways, construction of retaining walls, transport galleries, columns, walls and floors of industrial buildings, high rise buildings, toroidal, domed, cylindrical and conical vaulted structures, including underground and underwater, stationary and mobile platforms for the extraction of hydrocarbons on marine shelves, as well as for constructions exhaust chimneys, cooling towers, sea and river berths and terminals; may use such constructions in shipbuilding.

Known for the large concrete structure, widely used in industrial and civil construction, carrying its own weight, external loads, and possibly the weight of the aggregate, do not apply due to the complexity of their formation to ensure the reliability and durability of the planned creation of structures, especially in labor-intensive monolithic mounting blocks in the composite and using forms and manual labor for installation of reinforcement in reinforced execution.

Known in building construction in the form of a laying of the monolithic hollow building blocks (artificial stones) with different configurations of the cavities, probably filled with other materials [1].

However, after Assembly, the wall of such bearing elements into a stone monolith, it is highly susceptible to cracking and chipping when irregular precipitation and large local impacts. This array does not have the ability to effectively dissipate the local high-temperature fields generated by sources of different origin. With the increase of the characteristic sizes of the created structures is complicated by the technology of erection of structures, the pace of construction.

Known design connection modular mounting blocks, including embedded parts, in the form of metal clips cylindrical is army, posted in concrete docked elements in the zone of the joint, the internal volume of which is pre-filled adhesive composition, and a metal link - rod, one end of which is slid into the metal ferrule of one of joined element, and the other in a metal cage joined another element. When a metal ferrule on the end face is welded to the bore of the flange forming the locking funnel capture [2].

However, in the known design mounting connections should be provided with high precision in placement of inserts in concrete, which is difficult, because the embedded parts of small diameter pipes, it is difficult to fix formwork erection of reinforced concrete elements rigidly, with small tolerances on the location and accommodation on the borders of the installation of concrete blocks or concrete mass, which attaches the unit or group installation of concrete blocks. Actually this design is only functional when the mutual contact of two blocks or one block with a concrete array with a limited number of joints on the fixing rod inserts. Possible pre-installation rod or several rods in one unit, but when misalignment and variations in the distances between the joint parts of blocks, increasing to process the e concreting, when stiff enough to fix details of joints in formwork to ensure the proper connection of the mounting blocks is impossible. Use the glue to the force of clamping structures is not possible to provide greater load-bearing capacity of multi-unit spatial structures, especially when carrying out installation work at negative ambient temperatures below minus 10°C, especially in regions with harsh climatic conditions.

Known honeycomb structure made of a flexible polymer tape installed on the edge and interconnected linear welds, such as Geocaris" - volume geogrid, forming filling the soil geocity intended to improve the construction of the properties of different soils and applied for erosion protection of slopes, cones overpasses, reinforcement of weak bases, construction of retaining walls [3].

However, a honeycomb structure made of a flexible polymer tape has limited overall dimensions, does not provide a high stability of the structure.

Known for the design of deep-water artificial Islands, including the enclosing structure consisting of sections of the caissons, the bottom of which is the Foundation laid in rows in height, forming a closed loop, each section of the caisson bottom row performed in rikaline directional columns, and section caissons overlying series is equipped with a vertical tubular elements mounted in the cavity of each section throughout the height and mated with the guide columns [4].

However, in this solution, the tubular section connection design team has a specific solution for macro-objects underwater applications and is not summarized by geometric parameters and the shape of the mounting elements, and methods of their compounds into smaller structural elements of the universal destination.

The closest technical solution is a building block in the shape of a polyhedron with a through screw hole located at the center of the bottom and top faces, and paired with the fastening element in the form of rods with a length that is a multiple of the length of the at least one modular unit, with the possibility of svorachivaniya using a handheld power tool [5].

However, the known building block has a rudimentary geometric shape of the surfaces, the increased complexity of factory manufacturing and Assembly of the elements and their installation in the design position, expensive and complicated fastening element, which does not ensure the transfer of a relatively large effort between the contact blocks if you want to create large spatial design complicated patterns, especially balsara is tnou, with spans of tens or hundreds of meters.

The most important problem of creating structures of the above classes of prefabricated composite bearing blocks is to develop constructive solutions to their mounting connections.

Received widespread introduction of hard Association and Assembly of concrete blocks into a single structure by welding fittings or welding through a sheet of flat lining fixings, followed by concreting the field joint in removable or remaining formwork [6].

The disadvantage of this conventional method is the high complexity of the splicing reinforcement, as well as the presence of a complex of works on installation and removal of formwork and concreting process connection. The installation process may be hampered by the need to work in difficult climatic conditions of the construction site. The conventional metal inserts in the mounting of reinforced concrete elements, requires a large amount of work on the adjustment of parts and their coupling by welding or bolting.

In all known butt decisions, as well as in connection with connection fittings with subsequent concreting joint area during installation for flat or spatial thin-walled reinforced concrete structures cannot use the SQL mounting joints to effectively increase the bearing capacity of structures by fixing in the connecting joints of rigid metal load-bearing elements, working on the principle of external reinforcement and forming a complex combination structure of spatial structures of large spans, heights or lengths.

Objectives of the invention are:

- the specification of the geometrical shape of the surface, structure, composition, and location of the metal component units prefabrication to create a high rate of build cost-saving materials and construction of large structures, including the cell, structure, and use of hard and technological mounting connection blocks and, if necessary, with the formation of the combined systems of the mounting blocks and the adjacent outer rod elements;

- ensuring the carrying capacity, durability and, if necessary, the tightness of the generated structures, as well as improving the technology of installation of precast concrete building structures by creating reliable and versatile mounting interface with rigid attachment of joined blocks from the elastic displacements.

Solving these problems is achieved by the fact that the composite bearing block representing a spatial polyhedron or its fragment with through cavities in the faces, including concrete, rebar, embedded parts in the form of hollow elements, whic is in its end-to-end cavities, serving for connection of the mounting blocks between themselves and with other elements of the design with the use of guard elements of the mortgage inserted during installation of modular design in embedded parts, according to the invention is made with open or closed cavities, open, fully or partially closed single and multiply connected cross sections or in the form of fragments, at least one thick-walled shell or plate, and the surfaces of the outer faces, the inner cavities, membranes, and plates attached to such geometric shape from a combination of flat, curved linear or spherical surfaces, and also has such geometrical dimensions of the holes embedded items and such location coordinates of these parts in the mounting block, which as a result of the installation provide education team building structures with the desired dimensions and a given spatial bulky structure of the bearing faces of the cavities and channels and embedded parts rigidly connected with additional rod embedded items, adjacent the outer side.

The verge of the composite bearing block or its fragments in the form of shells open path and plates may include tightly coupled with the reinforcement and concrete load-bearing elements of the steel sheet PR the kata in the form of plates and shells with bar median surfaces.

The surface of the mounting block may have protrusions in the form of ribs. Embedded parts of the composite bearing block is made of pipe segments, for example, steel. Additional core embedded parts made in the form of contours, covering sections of pipe, for example, from a bent steel bar reinforcement welded to the pipe and to each mortgage loan items is adjacent at least two additional rod fixings.

These objectives are achieved simultaneously and the fact that in team building constructions composite bearing blocks, including embedded parts in the form of hollow elements of the pipe lengths during installation to form a through hole that passes coaxially through all combined in one joint of the composite load-bearing blocks, and, according to the invention, the closing of the mortgage loan element is also made of the hollow tube segment, for example, of steel or of its fragments and rigidly attached at its ends to mortgage the tubular elements of the mounting blocks or steel reinforcing rods rigidly attached along its length to the inner surfaces of embedded tubular elements. The closing of the mortgage loan element may have fasolki - longitudinal plates with holes for connection of the mounting blocks further rod embedded items through closing mortgage loans El the cops. The closing of the mortgage loan element may have on its outer surface, at least one end-to-end longitudinal groove to be filled before the hard attachment to the fixtures, for example, fine-grained quartz sand or hardened liquid filler. The interface may optionally be provided with at least one longitudinal aperture, for example, of steel, made of a plate rigidly attached to the inner surface of the trailing laying element, the longitudinal length of the aperture is not less than the longitudinal dimension of the through cavity of the junction formed by embedded items, and at least one end section of the longitudinal aperture has holes for mounting bolts. The closing of the mortgage loan element is further provided with at least one transverse aperture. In the cavity trailing laying element, or in the space between structures or between mortgage closing element and embedded items entered aggregate of stiffening material, such as concrete.

The proposed solution prefabricated building structures from composite bearing blocks prefabricated provide opportunities for mass application of precast concrete in the innovative basis of constructive forms of responsible engineering constructions in the industrial, transport is m and civil construction.

One of the most important technological features of modular composite structures - an exceptionally high rate of Association and Assembly units in a variety of complex spatial constructive forms with sufficient reliability and ease of installation joints using embedded parts. Mortgage details such joints simplify the creation and maintenance of an inventory of formwork forms for prefabricated reinforced concrete shell and plate mounting blocks for various purposes and a wide variety of configurations.

Composite bearing block for team building structures, such as large-sized honeycomb structure made in the form of a spatial polyhedron, with through holes in the sides, and includes concrete, rod reinforcement, trailing embedded parts in the form of hollow tubular elements located in the through holes. These holes are used to connect the mounting blocks between themselves and with other elements of the design using embedded fasteners that are inserted during Assembly into the base part. The mounting block has open or closed cavity or fragment, at least one thick-walled shell or plate with an open, fully or partially closed single and multiply connected cross-section.

Surfaces of the outer faces, the inner cavities, membranes, and plates attached to such geometric shape from a combination of flat, curved linear or spherical surfaces, as well as the geometric dimensions of the holes with concrete inserts and such location coordinates of these parts in the mounting block, which as a result of the installation provide education team building structures with the desired dimensions and a given spatial bulky structure, including cellular, bearing edges, cavities and channels.

One of the most important technological features of modular composite structures - an exceptionally high rate of Association and Assembly units in a variety of complex spatial structural shapes, including in the form of honeycomb structures, with sufficient reliability and ease of installation joints using embedded parts. Mortgage details such joints simplify the creation and maintenance of an inventory of formwork forms for prefabricated reinforced concrete shell and plate mounting blocks for various purposes and a wide variety of configurations.

In addition to attaching to the mounting blocks external to their core group of bearing elements, the outer surfaces of the blocks or the inner region may include hard is knitted with the reinforcement and concrete load-bearing elements of the steel sheets in the form of plates and shells with bar median surfaces.

Embedded parts of the pipes must be geometrically the same nominal cross-section on each of the internal hole.

Rigid and geometrically accurate (within tolerances specified in the construction project) mutual spatial arrangement of zakladni the details of each installation of concrete block shall be provided by the structure of the reinforcement cage and the design of the formwork, typically, inventory, multiple re-use.

Embedded parts of the pipes allow the use of its opening for the passage through them of fasteners, accurately and rigidly clamping parts inventory formwork during concreting until its dismantling after a set of concrete specified strength.

Closing inset element mounting connection must have design dimensions of the outer contour of the cross-sections smaller than the design size of the contours of cross-sections of the inner surface of inserts that when the Assembly is free to proceed in accordance with the established project tolerances through all joined with this closing laying element mounting concrete blocks, and for more accurate installation, you can use a longitudinal groove, fill in fine-grained quartz sand or hardened liquid placeholder.

The length of the closing of a mortgage item should be adopted taking into account the need welding in the Assembly process design, at least one of its ends fixtures mounted at the element.

The internal cavity closing laying element may have a transverse aperture and to be concreted or filled with another stiffening substance.

During Assembly of the connection, and after its completion in contact and adjacent to the joints of the surface adjacent the mounting of reinforced concrete elements and the surface of the closing element can be covered with anti-corrosion and waterproofing materials.

Assembly units in the building structure during the construction of foundations, walls, footings, columns, domes, subgrade of roads and other facilities as follows: mounting blocks certain design placed on the prepared base to reflect the technological requirements and are fastened to each other and other elements of the building structure using mortgage closing element 7, which is welded to the fixtures 1. The mounting blocks and trailing embedded elements 7 are made in the factory of various structural materials, which minimizes labor on a construction site.

ontogeny the junction blocks prefabricated building structures is as follows. During operation created precast concrete structures internal potential energy of deformation is accumulated and distributed between design and aggregate in accordance with the laws of mechanics of deformation of solids within the spatial task. The load on the individual unit through the mounting joints connects the adjacent block, which, in turn, engages the next, which increases the carrying capacity of the created structures. The peculiarity of the construction of the proposed design is the possibility of separation in time of the individual steps. First can be manufactured elements, and then performed their Assembly and Association the joints, which provide a reliable connection plates and simplify technology.

The cellular structure of the proposed mounting blocks used in construction for the formation of spatial systems of hollow load-bearing units, as well as a lattice of thin-walled planar and spatial detail. Such rigid body and a flexible tape formed in the bearing structure in process of erection of structures closed cavity or mesh structure, in particular, filled with soil or stiffening agents. Created by the construction and design of large cellular structures have developed geometries the e form surfaces, budget fasteners provide transmission of a relatively large effort between the contact mounting blocks if you want to create large spatial design complex structures, especially large spans of tens or hundreds of meters, simple in manufacture and installation for high-altitude, long-span, surpateanu, including underwater, structures.

The use of modular construction reinforced concrete structures of the present invention provides sufficient strength required quality and rapid installation, high level typing and unification of projects on the utilization of the mounting blocks for the construction of objects of different branches of engineering and civil construction, primarily due to the possibility of mass production in modern plants concrete and metal products prefabricated mounting blocks and guard elements of the mortgage with the required geometric accuracy and stability properties of structural materials.
