СПОСОБ ВСКРЫТИЯ ЗАКЛАДНЫХ ДЕТАЛЕЙ И АРМАТУРЫ В ЖЕЛЕЗОБЕТОННЫХ ИЗДЕЛИЯХMETHOD OF OPENING MORTGAGE PARTS AND FITTINGS IN REINFORCED CONCRETE PRODUCTS
1one
Изобретение относитс к области строительства и может быть использовано при монтаже и демонтаже железобетонных изделий и сооружений.The invention relates to the field of construction and can be used in the installation and dismantling of concrete products and structures.
Известен способ вскрыти закладных деталей и арматуры в л елезобетонных издели х путем разрушени прилегающего к ним сло бетона с помощью ручного или механизированного инструмента ударного действи .There is a known method for opening embedded parts and reinforcement in concrete products by destroying the layer of concrete adjacent to them using a hand-held or mechanized percussion tool.
Одн:ако при этом способе из-за высокой твердости бетона не удаетс уберечь от повреждени вскрываемые детали и арматуру.One: In this method, due to the high hardness of the concrete, it is not possible to protect the parts and reinforcement from damage.
Цель изобретени - сохранение от повреждени вскрываемых закладных деталей.The purpose of the invention is to preserve the embedded parts from damage.
Дл этого производ т поверхБОствый нагрев металла индуктором ТВЧ до разрущени сло бетона, прилегающего к закладной детали .For this purpose, metal is heated on top of a high-frequency inductor by the inductor until the layer of concrete adjacent to the embedded part is destroyed.
Если поверхностный слой закладной детали или арматуры, располагаемых в бетоне на глубине 10-30 мм, нагреть индуктором ТВЧ до 600-700° С, то объемна температурна деформаци металла вызовет по вление микротрещин в прилегающем слое бетона. В вагретой поверхности бетона будет происходитьIf the surface layer of the embedded part or reinforcement located in concrete at a depth of 10–30 mm is heated with an HDTV inductor to 600–700 ° C, then the volume temperature deformation of the metal will cause the appearance of microcracks in the adjacent layer of concrete. In the watered surface of the concrete will occur
изохронный процесс вследствие нагрева воздуха и влаги в порах бетона, а также интенсивное вскипание воды, что влечет за собой разрущение сло бетона, прилегающего к нагретой зоне металла.the isochronous process due to the heating of air and moisture in the pores of concrete, as well as intensive boiling of water, which entails the destruction of a layer of concrete adjacent to the heated metal zone.
Способ осуществл ют в следующей последовательности . Накладывают индуктор ТВЧ на бетон в месте расположени детали (желательно иметь зазор между индуктором и б(;тоном пор дка 0,5 - 1 мм). Включают питание , и через несколько секунд (что зависит от глубины залегани металла, состава бетона и т. п.) происходит выброс бетона, прилегающего к нагретой зоне закладного металла.The method is carried out in the following sequence. An HDTV inductor is placed on the concrete at the location of the part (it is desirable to have a gap between the inductor and b (; tone of about 0.5-1 mm). Turn on the power and after a few seconds (depending on the depth of the metal, the composition of the concrete, etc.) p.) there is a release of concrete adjacent to the heated zone of the embedded metal.
