Description

При производстве бетонных работ в зимнее врем  примен ют один из следующих способов обогрева , обеспечивающий получение бетона нормальной прочности:In the production of concrete work in the winter, one of the following methods of heating is used, which provides concrete of normal strength:

J) сооружение отапливаемых тепл ков вокруг сооружаемых конструкций ,J) the construction of heated heat sinks around the structures under construction,

2)поддержание нужной температуры конструкции электронагревательными приборами или паровым подогревом,2) maintaining the desired temperature of the structure with electric heaters or steam heating,

3)сохранение тепла, образующегос  при экзотермическом процессе отвердевани  бетона, сооружением теплоизол ции конструкции .3) preservation of heat generated during the exothermic process of hardening of concrete, construction of thermal insulation of the structure.

Первый способ может быть применён везде, но он дорого обходитс  и поэтому мало пригоден дл  практического использовани .The first method can be applied everywhere, but it is costly and therefore not very suitable for practical use.

Второй способ св зан с наличием электроэнергии или пара и не везде, поэтому, может быть применён .The second method is associated with the presence of electricity or steam and not everywhere, therefore, it can be applied.

Третий способ наиболее экономичен ,, но, не даёт проектной прочности бетона до наступлени  тёплого времени года.The third method is the most economical, but does not give the design strength of concrete until the warm season.

Автор насто щего изобретени  предлагает при зимней укладке бетона примен ть нагревательные массы из негашёной извести, покрытой слоем гигроскопического вещества, например, древесными опилками, увлажнёнными в месте соприкосновени  с известью. Между слоем бетона и известью помещают толь или пергамин.The author of the present invention proposes to apply heating masses of burnt lime covered with a layer of hygroscopic substance, for example, sawdust moistened at the place of contact with lime, during winter laying of concrete. Between a layer of concrete and lime, tol or glassine is placed.

Слой гигроскопического вещества  вл етс  термоизол ционным слоем и может быть частично заменён термоизол ционными плитками .The hygroscopic substance layer is a thermal insulation layer and can be partially replaced by thermal insulation tiles.

Толодину сло  извести и теплоизол ционного сло  определ ют теплотехническими расчётами, исход  из потребных сроков остывани  и внешней температуры.The lime layer and the heat insulating layer are determined by thermal engineering calculations, based on the required cooling time and external temperature.

Скорость гащени  извести, а равно и скорость выделени  при этом процессе тепла, регулируетс  различней дозировкой воды.The rate of lime absorption, as well as the rate of heat release during this process, is regulated by different dosages of water.

Списанный способ дал весьма хорощие. результаты при бетонировании железобетонных фундаментов под опоры высоковольтнойWritten off method gave very good. results when concreting reinforced concrete foundations for high-voltage supports
