Abstract

FIELD: civil engineering. SUBSTANCE: structure is comprised of artificial stone with embedded reinforcement bars. Before manufacture of stone the latter is filled with intercommunicating sealed rigid synthetic pipes arranged in a regular pattern while the reinforcing bars are placed inside the pipes, being anchored in plan at the ends only. Pipes communicate with the atmosphere through one upper and one lower pipe unions which can be filled with expanding liquid when the service life of the structure is completed. EFFECT: improved design.

Description

 The invention relates to construction, namely to all structures made of artificial materials that have a limited life and after which they must be destroyed for recycling components.

 Known methods for the destruction of stone materials with the aim of their secondary use as a large aggregate for concrete and the extraction of steel reinforcement. For this purpose, for example, destructive means are used (they are destroyed into elements of random sizes by hammers, explosives, hydro-explosions, with electro-hydraulic effect, etc.) or disintegrating actions - the structure is disassembled into elements of specified sizes by sawing, drilling, cutting, etc. ( 2).

 All these methods have significant disadvantages, which include the application of force on the structure, the complexity, the complexity of operations, the difficulty of obtaining small-sized identical stones and the allocation of intact reinforcement.

 The closest in technical essence and the achieved positive effect to the claimed invention is a known device - a heat-insulating panel (1). In this panel, throughout its thickness, the same balls are placed inside the framing element with air gaps between the balls. Thus, if disassembly is necessary, it is only necessary to destroy or disassemble the framing element, and the balls can be reused immediately immediately as a placeholder.

 The disadvantage of this design, which we selected for the prototype, is the impossibility of placing reinforcement between the balls, the relatively low strength of the material with air layers, the inability to perform load-bearing reinforced concrete structures (1).

 The aim of the invention is the creation of reinforced strong load-bearing structures for any purpose made of artificial stone, which, after exhaustion of the service life, could be virtually waste-free, without negative environmental impacts, could be destroyed without the application of any external forces of a violent nature, while stones of approximately the same would be obtained size and undeformed fittings.

 The essence of the invention lies in the fact that even in its manufacture a reinforced concrete structure is pre-installed with a regular structure of rigid synthetic interconnected tubes, after concreting connected to the external environment using one upper and one lower nozzles. Steel reinforcement is also placed inside these tubes and is anchored only at the ends with the help of any broadening. At the ends of the tubes in the places where the fittings are installed, seals are installed to ensure the tightness of the tubes. The diameter of the reinforcement should be 2-3 mm less than the inner diameter of the tubes. If it is necessary to separate the structures into separate stones of approximately the same diameter and isolate the reinforcement, some expanding liquid (for example, water expanding during freezing) is introduced into the tubes through the upper nozzle, and after the expansion of the liquid, the structure is destroyed.

 In FIG. 1 shows a beam 1 with reinforcement 2 and synthetic tubes 3 arranged in a structure, with upper 4 and lower 5 nozzles through which the tubes 3 communicate with the atmosphere and with seals 6 at the ends of the tube 3 at the location of the reinforcement 2.

 Figure 2 shows the beam 1, divided into separate blocks (pieces) of concrete of approximately the same size 7.

 In the manufacture of a self-destructive structure, a structure of rigid synthetic tubes 3 with upper 4 and lower 5 nozzles is installed in the formwork. Inside the tubes 3 there are separate rods of reinforcement 2 with seals at the ends 6. The reinforcement may have anchoring devices at the ends. Concrete 1 is laid in the formwork, after hardening of which the beam can absorb the load. Moreover, the structure of solid synthetic tubes 3 can play the role of additional spatial reinforcement of the beam. Tubes 3 must be solid so as not to crumple under the influence of a freshly laid concrete mass.

 The method of use (work) of the self-destructive structure 1 is as follows: after the end of the operating life, it is necessary to open the nozzles 4 and 5 of structure 1, then pour into the tubes 3 through the nozzle 4 any expanding liquid during hardening (for example, water), and the nozzle 5 serves only to control the passage of fluid, and then it must be closed. After filling the tubes 3, for example, with water (it is advisable to carry out this operation in winter), the structure 1 is cooled and destroyed to separate concrete blocks 7 and the reinforcement 2 is highlighted.

 The technical and economic efficiency of the proposed self-destructive structure compared to the prototype is to provide environmentally friendly self-destruction of a solid supporting structure with complete waste-free disposal of all its components.
