Concrete shrinkage testing device under cold construction conditions

Abstract

The invention discloses a concrete shrinkage testing device under cold construction conditions. The structure comprises a window, a test host, a recycling box, universal wheels, a base and an operation panel. The window is embedded on the left side of the outer surface of the test host, and the lower end of the test host is connected with the recycling box. The test host is mounted on the base. Through transmission of a linkage belt, a linkage spindle rotates to drive a rotating rod to rotate, and then a placement plate on the upper end of the rotating rod also starts to rotate so as to perform more comprehensive testing of concrete. After a compression tube performs air compression, compressed air is blown out through an air outlet to drive rotating fan blades to rotate. Thereby, throughthe simulation testing of the concrete with large cold wind, shrinkage of the concrete under cold conditions can be detected. The left end of a second traction plate is shifted to the right side and the right end is shifted to the left side to touch a power box, and then a water pump works and water inside a water tank is more powerfully discharged to a shower head for cold water spraying testingof the concrete. The test effect is more obvious.

Description

technical field [0001] The invention is a concrete shrinkage test device under cold construction conditions, which belongs to the field of concrete shrinkage test devices under cold construction conditions. Background technique [0002] Super high-rise buildings are favored by builders due to their high land utilization rate, promotion of scientific and technological progress, and significant improvement of the city's image. Affected by the construction period, the shear wall structure concrete cannot be maintained with molds for a long time, while the vertical suspension shear wall concrete Usually, it is exposed to the air due to the difficulty of maintenance after form removal. The cold and windy environment in winter in the cold regions of northern my country poses a huge challenge to the concrete maintenance of super high-rise buildings. Among them, shear walls are often affected by large internal and external temperature differences and strong winds. Harmful cracks, This...
