Concrete in-mold temperature control system applied to cold conditions

Abstract

The invention discloses a concrete in-mold temperature control system applied to cold conditions, the control system comprises a heating device; the heating device is arranged on a steel bar to be poured and is connected with the steel bar, the heating device is connected with a power supply bus through a cable, and the heating device is poured in a concrete structure. The temperature required by initial setting and final setting of the concrete can be effectively controlled, early freezing of the concrete is avoided, the early strength of the concrete is guaranteed, mass concrete cracks are reduced, and the later strength and durability of the concrete meet the requirements.

Description

technical field [0001] The application belongs to the technical field of cement concrete, and in particular relates to a temperature control system for concrete entering molds under cold conditions. Background technique [0002] Too low temperature often causes early freezing damage of concrete cast-in-place components, which greatly reduces the safety and durability of the project, and significantly affects the quality of project construction. Long-term continuous negative low temperature, large temperature difference, snowfall and repeated freezing often cause quality accidents in construction. In addition, urban construction in some areas is also prohibited from construction due to the cold winter, which seriously hinders the pace of construction, lengthens the construction period, increases capital and management costs, prolongs the investment recovery period and reduces the ability to avoid macro risks. Resulting in a reduction in capital turnover and a substantial inc...

Long-term continuous negative low temperature, large temperature difference, snowfall and repeated freezing often cause quality accidents in construction

In addition, urban construction in some areas is also prohibited from construction due to the cold winter, which seriously hinders the pace of construction, lengthens the construction period, increases capital and management costs, prolongs the investment recovery period and reduces the ability to avoid macro risks. As a result, the capital turnover rate has decreased and the construction cost has increased significantly.
