Novel multifunctional integrated concrete test block curing box

Abstract

The invention discloses a novel multifunctional integrated concrete test block curing box which comprises a box body, an LED display screen, a disc type heating pipe, a liquid level sensor, a communicating glass pipe, a cooling fan, a frame plate, a PLC and a steam generator. A large box cover is arranged on the top of the box body. A water escape valve and the communicating glass pipe are arranged on the left side face of the box body. The disc type heating pipe is arranged on the bottom in the box body. A frame plate piece is arranged on the top of a supporting leg of the frame plate. A thermocouple sensor and a temperature and humidity sensor are arranged in the box body. A controller protecting box is arranged on the back face of the box body. The LED display screen, the disc type heating pipe, the liquid level sensor, the cooling fan, the thermocouple sensor, the temperature and humidity sensor, a timer module and the steam generator are electrically connected with the PLC. According to the curing box, traditional three curing modes of standard curing, steam curing and boiling water curing are combined together, integration of different curing functions is achieved, and greatconvenience is provided for researchers in the field of concrete materials.

Description

【Technical field】 [0001] The invention relates to a novel multifunctional integrated concrete test block curing box, which belongs to the technical field of concrete curing equipment. 【Background technique】 [0002] In the field of concrete material research in the world, it is often necessary to conduct a series of tests on concrete test blocks such as strength, impermeability, durability, and freeze-thaw cycle resistance, and concrete test blocks need to be cured under certain conditions to achieve their design strength. related tests can be carried out. Concrete test block maintenance is mainly to create conditions to meet the full hydration reaction of cement, accelerate the hardening of concrete, and make it reach the design strength requirements within the specified time. Abnormal shrinkage, cracks and other phenomena occur. [0003] The curing temperature has a great influence on the development speed of the early performance of concrete. Generally speaking, the hi...

Problems solved by technology

Compared with standard curing and steam curing, boiling water curing greatly shortens the time for concrete specimens to reach 28d strength, but when using existing curing equipment for boiling water curing, it is often necessary to control the heating and cooling rates of the water body, while the traditional curing box Both heating and cooling rates cannot be controlled artificially, and there is often a fixed heating power during heating, which cannot be artificially changed, and can not meet the control experiments of different heating rates; when cooling, the lid is usually opened to cool down naturally, but as the season changes, the cooling rate also changes. always changes, which has some influence on the results of longer-period experiments
