Изобретение отиосите  к строительству, преимущественно к железобетонным изгибаемым конструкци м, и может быть использовано дл  кратковременного новышени  их несуш,ей снособности .The invention of design for construction, mainly for reinforced concrete bending structures, and can be used for short-time laying them, her ability.

Известен способ усилени  элементов железобетонных сооружений металлическими или железобетонными разгружающими конструкци ми .There is a method of reinforcing elements of reinforced concrete structures with metal or reinforced concrete unloading structures.

Недостатками такого способа  вл ютс  сложность производства работ, высокие материальные затраты и увеличение габаритов усиливаемых элементов.The disadvantages of this method are the complexity of the work, high material costs and an increase in the dimensions of the reinforced elements.

Известен также способ усилени  железобетонных элементов при номощи полимерных материалов, по которому на эксплуатируемую конструкцию нанос т шнателем слой полимерного эпоксидного материала, затем обертывают железобетонный элемент стеклотканью с последующей нроииткой ткани тем же полимером .There is also known a method of reinforcing reinforced concrete elements using polymeric materials, by which a layer of polymeric epoxy material is applied to the operated structure, then the reinforced concrete element is wrapped with fiberglass followed by fabric with the same polymer.

К недостаткам указанного способа относ тс  трудоемкость нроцесса нанесени  полимерного материала, нроизводство работ на высоте, а также то, что на участках, где требуетс  кратковременное увеличение несущей способности, применение этого способа не экономично из-за высокой стоимости используемых полимерных материалов.The disadvantages of this method include the laboriousness of the process of applying a polymer material, the production of work at height, and the fact that in areas where a short-term increase in bearing capacity is required, the application of this method is not economical due to the high cost of the polymeric materials used.

Цель изобретени  - обеспечение временного повышени  несущей снособности железобетонных конструкций.The purpose of the invention is to provide a temporary increase in the bearing capacity of reinforced concrete structures.

Достигаетс  это тем, что в сжатой зоне железобетонной конструкции создают раст гивающие усили  нутем нагрева арматуры до температуры 200-400°С пропусканием через нее электрического тока.This is achieved by the fact that in the compressed zone of the reinforced concrete structure they create a stretching effect by heating the fitting to a temperature of 200-400 ° C by passing an electric current through it.

Иа чертеже показана схема реализации предлагаемого способа усилени  железобетонной конструкцнн.The drawing shows a diagram of the implementation of the proposed method of reinforcing reinforced concrete construction.

Усиление железобетонной конструкции 1 осуществл ют иодключеиием сжатой арматуры 2 к источнику 3 электрической энергии. Контролируют нагрев арматуры амнерметром 4 и термодатчиком 5.The reinforced concrete structure 1 is strengthened by connecting the compressed reinforcement 2 to the source of electrical energy 3. Control the heating of the reinforcement with an amnermeter 4 and a thermal sensor 5.

Выполн ют способ в следующей последовательности .The method is carried out in the following sequence.

Сиачала, пропуска  электрический ток, нагревают сжатые стерл ни, изолированные от остального арматурного каркаса, благодар  чему происходит усиление железобетонной конструкции, например моста, в соответствии с предлагаемым способом. Затем пропускают транспортное средство, после чего сжатую арматуру обесточнвают.Sachala, the electric current transmission, heats up the compressed pads, isolated from the rest of the reinforcement cage, due to which reinforcement of the reinforced concrete structure, such as a bridge, occurs in accordance with the proposed method. Then the vehicle is passed, after which the compressed reinforcement is de-energized.

Пре.п,лагаемый способ временного усилени  обеспечивает снижение металлоемкости по сравнению с известиыми способами и высокую экономическую эффективность.The Pre.p, lagging method of temporary reinforcement provides a reduction in metal consumption compared to lime methods and high economic efficiency.

Способ усилени  изгибаемых железобетоииых конструкций путем создани  раст гивающих усилий в сжатой зоне, о т л и ч а ющ и и с   тем, что, с целью обеспечени  временного повышени  несущей способности железобетонных конструкций, раст гивающие усили  в сжатой зоне создают нагревом арматуры до 200-400°С нри пропускании электрического тока.The method of strengthening flexural reinforced concrete structures by creating tensile forces in a compressed zone, which also means that, in order to ensure a temporary increase in the bearing capacity of reinforced concrete structures, tensile forces in the compressed zone are created by heating the reinforcement to 200 400 ° C by passing an electric current.
