Definitions
- the group of inventions relates to the field of construction, namely to building structures and methods for manufacturing building structures with non-tensioned and prestressed reinforcement, and can be used in the construction of residential, public and administrative buildings and structures, as well as in their restoration or reconstruction.
- the group of inventions can be used for the manufacture of building structures, mainly road, airfield, slabs, including prefabricated monolithic house-building, floor slabs, slabs for tram tracks, for railway tracks, slabs for subway tracks, bridges, rafters, enclosing structures - wall panels, including multilayer, randbalks, floor beams, etc.
- the closest set of essential features to the claimed multilink building element is a multilink concrete product disclosed in international application WO 2011/065863, published 03.06.2011, which contains stretched metal ropes and at least two hollow links made of concrete with internal fittings having through longitudinal channels.
- the mentioned links are sequentially interconnected by means of the said ropes, each of which is placed in the said longitudinal channels and anchored at the non-adjacent ends of the links.
- the prior art method for the construction of prefabricated pavement disclosed in patent RU 2379406, published 01/20/2010.
- the method includes laying prestressed rectangular or square reinforced concrete slabs on an earthen, sand or other base, fastening the slabs to each other in one or two mutually perpendicular directions using through fittings in the channels with its subsequent tension, sealing the joints between the slabs with a sealed material, coating the concrete foundations with asphalt or cast asphalt.
- the reinforced concrete slabs are fastened by pulling steel ropes into packages containing from 5 to 20 slabs with subsequent tension with a force of 5 to 30 ton-force per rope, while elastic elements are put on the ropes between the ends of the slabs, the steel ropes are placed in through channels located in the middle of the slabs, and the ends of the ropes after tensioning are fixed with anchors in the fastening cavities of the extreme in packs of plates with monolithic cavities with concrete.
- the disadvantage of this method is the low efficiency in the construction of objects of considerable length or objects of complex shape, because the restriction on the length of the strained steel ropes entails the manufacture of the object as a whole prefabricated from separate stressed elements, and as a result, the bearing capacity, stability, rigidity and crack resistance of the object are reduced.
- the closest set of essential features to the claimed method is the method of assembling a multi-link product disclosed in international application WO 2011/065863, published on 06/03/2011, which consists in the use of hollow concrete links with internal reinforcement having through longitudinal channels to orient the above-mentioned links so that the said channels are on the same axis, metal ropes are passed through the channels of concrete links with a winch, pulled by hydraulic jacks and anchor in a stretched state on the non-adjacent ends of the links.
- the disadvantage of this method is the low efficiency in the construction of objects of considerable length or objects of complex shape, because manufacturing of the object as a whole by prefabricated from separate stressed elements, and as a result - lower the object.
- the task to which the claimed group of inventions is directed is to create a pre-stressed building element and a method for assembling it, characterized by high bearing capacity, stability and rigidity at low material consumption and labor costs.
- each link is made in the form of a reinforcing module, consisting of initial and final support elements with holes for prestressed reinforcement and a platform for placement anchors and tensioning devices, and placed between the supporting elements of the reinforcing cage, including the upper and lower elements in the form of a lattice with a cellular structure with cells in the form of an equilateral polyhedron, and at least one middle element in the form of a spatial reinforcing structure containing inclined reinforcing bars that form oppositely oriented equilateral polyhedral pyramids in space, while the prestressed reinforcement of the first link is anchored at its initial and final supporting elements, and the prestressed reinforcement of each subsequent link is anchored at the finite elements of the previous and current links.
- the multi-link building element can be additionally equipped with lateral support elements placed at an angle of 0 ° ⁇ a ⁇ 180 ° to the longitudinal axis of the building element with the possibility of prestressing in the direction at an angle of 0 ° ⁇ a ⁇ 180 ° to the longitudinal axis of the building element.
- rod and / or rope reinforcement is used, while tubular channel formers can be provided for the latter.
- At least one of the elements of the reinforcing module can be made monolithic, and the upper and / or lower elements and / or reinforcing bars of the middle element of the reinforcing module can be made of metal, or composite materials based on basalt or carbon, or fiberglass, or polymeric materials, or polymeric materials with reinforcing additives.
- the upper and / or lower elements are made with the possibility of fastening the panels.
- the space between the reinforcing rods of the middle element of the reinforcing module can be filled with filler, which can be used as concrete, or polymeric materials, or polymeric materials with reinforcing additives, or soundproofing materials, or heat-insulating materials.
- filler which can be used as concrete, or polymeric materials, or polymeric materials with reinforcing additives, or soundproofing materials, or heat-insulating materials.
- pipes for communications can be placed in the space between the reinforcing rods of the middle element of the reinforcing module, at least some of which are made with inspection hatches to allow installation or diagnostics of the state of communications
- non-contact electromagnetic power means can be placed for power, for example, electric vehicles moving on a transport bed, or means of heating a building element.
- At least part of the reinforcing rods of the middle element of the reinforcing module can be made with outlets to ensure contact with the monopolistic or underlying layer.
- the specified technical result is also achieved due to the fact that in the method of assembling a multi-link building element, the middle, upper and lower elements of the reinforcing module are pre-assembled, they are fixed between the initial and final supporting elements, the reinforcement is installed and then it is pre-stressed, while starting from the second reinforcing module in the product, the prestressed reinforcement anchor is installed on the final supporting element of the previous reinforcing module, and the tensioning device of - pre prestressing module on the target support member.

- figure 2 multi-link building element, top view
- figure 3 shows a view of figure 2
- figure 4 shows a view of B in figure 2;
- figure 5 shows a view in figure 2
- figure 6 multi-link building element with prestress both across the reinforcing module and in the direction at an angle of 0 ° ⁇ a ⁇ 180 ° to the longitudinal axis of the building element;
- a multi-link building element includes at least two links and prestressed reinforcement.
- the structural strength is determined by the design features of each link, its overall dimensions and build quality.
- Each link is made in the form of a reinforcing module.
- the proposed design of the reinforcing module used in a multi-unit building element consists of elements assembled according to the principle of, preferably, tetrahedral structures in single block.
- the reinforcement module consists of the initial (1) and final (2) support elements and the reinforcing cage (3) placed between them, including the upper (4) and lower (5) elements in the form of a lattice with a cellular structure with cells in the form of an equilateral polyhedron, and at least one middle (6) element in the form of a spatial reinforcing structure containing inclined reinforcing bars that form oppositely oriented equilateral polyhedral pyramids in space.
- the design of the reinforcing cage is arranged so that the axial lines of all the reinforcing elements converge at the central nodal points.
- the reinforcing cage can be made of metal, or composite materials based on basalt or carbon, or fiberglass, or polymeric materials, or polymeric materials with reinforcing additives.
- at least one of the elements of the reinforcing cage can, if necessary, be made integral.
- the voltage of the reinforcing modules is carried out through installation, followed by tensioning the prestressed reinforcement (7).
- the initial (1) and final (2) support elements are made with holes (8) for prestressed reinforcement (7) and a platform (9) for accommodating anchors (10) and tensioning devices (11).
- the prestressed reinforcement of the first link is anchored at its initial and final supporting elements, and the prestressed reinforcement of each next link is anchored at the finite elements of the previous and current links. This ensures the redistribution of loads in all mating links due to the prestressing circuit of the reinforcement and the transmission of these stresses to the nodal elements of the mating frames.
- Prestressed reinforcement can pass in the frame in one or more directions at the same time.
- the location of prestressed reinforcement in the reinforcing module, as well as the amount of prestressing, are determined by the design operational loads of a multi-link building element during its operation.
- Prestressed reinforcement is tensioned, preferably perpendicular to bending loads, and the installation location of prestressed reinforcement, the number of prestressed elements and the amount of prestressing are preliminarily determined by calculation or experimentally.
- the prestressed reinforcement in the reinforcing module can be unevenly distributed and shift from the center of the module to the sides of maximum tensile stresses.
- the ability to install prestressed reinforcement in several directions ensures the operation of the structure in cases where not only bending loads, but also loads combined with torque are applied.
- the design of the thrust elements provides the possibility of prestressing prestressed reinforcement of both individual reinforcing modules, as well as the combined voltage of two or more reinforcing modules with one prestressed reinforcement with transmission of stresses only to the nodal elements of the frames.
- arched structures which are affected by a complex system of bending and torque loads in various directions.
- the possibility of calculated prestressing of such structures, with the effect of reinforcing them at the places of maximum tensile stresses, will solve many engineering problems in the construction of lightweight roofs, arched bridges, elevated pedestrian crossings, etc.
- the mating links in the connection planes are made with bevels that ensure the radius of the arch, assembled from many links.
- rods and ropes made of metal, polymers (carbon, lavsan), carbon plastics can be used.
- the design of persistent and tension elements allows for multiple, full or partial assembly of the structure and adjustment and control of the tension of prestressed reinforcement during operation.
- At least one rod or rope of prestressed reinforcement is passed through the corresponding hole of the initial supporting element of the first reinforcing module and secured with an anchor to the initial supporting element.
- prestressed reinforcement is passed through the first and subsequent reinforcing modules through the holes of the final supporting element of the first module and the opening of the initial supporting element of the next module and it is tensioned by means of an appropriate device, for example, a turnbuckle.
- the prestressed reinforcement anchor is installed on the final supporting element of the previous reinforcing module, and the tensioner on the final supporting element of the prestressed reinforcing module, after which the reinforcement is tensioned by means of an appropriate device, for example, a turnbuckle.
- This assembly sequence makes it possible to create multi-kilometer multi-link structures, for example, roadbed, which operate as a single prestressed structure, which is not possible with a different assembly method due to restrictions imposed by the strength of prestressed reinforcement and its length, as well as the difficulty of transmitting prestressed reinforcement through a multi-kilometer assembly.
- such an assembly can, if necessary, be disassembled in one of the sections, for example, for repair, and reassembled, which is not possible with a multi-kilometer roadbed with one prestressed reinforcement.
- tubular channel formers are introduced into the reinforcing module, through which prestressed reinforcement is passed.
- the prestressed reinforcement is shifted relative to the center of the reinforcing module in the direction of the greatest bending loads. If several horizontal rows of prestressed reinforcement are used along the height of the reinforcing module, the prestressed reinforcement of each horizontal row can be tensioned with different forces with increasing tension in the direction of maximum bending loads (i.e. towards maximum bending).
- the prestress of the structure can be produced both across the reinforcing module and in a direction at an angle of 0 ° ⁇ a ⁇ 180 ° to the longitudinal axis of the building element (Fig.6), as well as in a plane perpendicular to the plane of the longitudinal tension of prestressed reinforcement (Fig.7).
- the reinforcing module is additionally provided with appropriate support elements (12).
- the supporting platforms of the supporting elements in the corresponding sections of the reinforcing module are beveled in the desired direction.
- the main properties of structures made on the basis of the described reinforcing module include the following:
- the listed properties allow the use of multi-link building elements based on the reinforcing module in the construction of roads, airfields, buildings and other structures.
