Description

Известны способы изготовлени бетонных и железобетонных изделий путем центрифугировани с одновременным разогревом.Methods are known for the manufacture of concrete and reinforced concrete products by centrifuging with simultaneous heating.
Однако известный способ не предусматривает высоких скоростей нагрева и повышени температуры более 100°С, что увеличивает продолжительность процесса тепловой обработки .However, the known method does not provide for high heating rates and temperature increases above 100 ° C, which increases the duration of the heat treatment process.
Цель изобретени - сократить врем тепловой обработки и улучшить физико-механические свойства бетона.The purpose of the invention is to reduce the heat treatment time and improve the physicomechanical properties of concrete.
Достигаетс это тем, что нагрев осуществл ют в электромагнитном поле со скоростью 2,5-15°С в минуту до 180°.This is achieved by heating in an electromagnetic field at a speed of 2.5-15 ° C per minute up to 180 °.
По предлагаемому способу собранна форма устанавливаетс на центрифугу, расположенную внутри обмотки - индуктора или каким-либо другим образом, обеспечивающим замыкание индуктируемого электромагнитного пол на форму издели . Одновременно включаетс центрифуга и обмотка индуктора. Производитс распределение бетонной смеси внутри формы под действием центробежных сил и одновременно нагрев формы и арматуры в электромагнитном поле тока промышленнойAccording to the proposed method, the assembled form is mounted on a centrifuge located inside the inductor winding or in some other way ensuring the closure of the induced electromagnetic field to the shape of the product. At the same time, the centrifuge and the inductor winding are turned on. The concrete is distributed inside the mold under the action of centrifugal forces and at the same time the mold and the reinforcement are heated in the electromagnetic field of an industrial current.
.частоты с кондуктивной передачей тепла бетону . Создаетс возможность вести нагрев бетона с большой скоростью без опасени образовани деструктивных процессов, так как центробежные силы, перемеща и уплотн бетонную смесь, посто нно ликвидируют возможные нарушени структуры, и к моменту окончани центрифугировани весь бетон издели имеет одинаковую температуру и равномерное уплотнение .Frequencies with conductive heat transfer to concrete. It is possible to conduct the heating of the concrete at high speed without fear of the formation of destructive processes, since the centrifugal forces, moving and compacting the concrete mix, constantly eliminate possible structural disturbances, and by the time of the end of the centrifugation all the concrete of the product has the same temperature and uniform compaction.
При герметизации торцов форм создаетс эффект автоклавировани и формы можно нагревать до 180°С. Затем производитс изотермическа выдержка и остывание изделий известными способами.By sealing the ends of the molds, an autoclaving effect is created and the molds can be heated to 180 ° C. Then isothermal exposure and cooling of products by known methods is carried out.
Предмет изобретени Subject invention
Способ изготовлени железобетонных изделий , заключающийс в центрифугировании с одновременным нагревом, отличающийс тем, что, с целью сокращени времени тепловой обработки и улучшени физико-механических свойств бетона, нагрев осуществл ют в электромагнитном поле со скоростью 2,5-15°С в минуту до 180°С.A method of manufacturing reinforced concrete products, which consists in centrifuging with simultaneous heating, characterized in that, in order to reduce the heat treatment time and improve the physicomechanical properties of concrete, heating is carried out in an electromagnetic field at a speed of 2.5-15 ° C per minute to 180 ° s
