Problems solved by technology

"External storage" refers to the use of thermal insulation materials to insulate the outer surface of concrete. This method is widely used, but the effect will be greatly reduced in cold environments or when the coverage of thermal insulation materials is uneven; "inner distribution" refers to the use of water pipes There are some disadvantages in this method. First, the construction site is complicated, and a large number of layouts affect the construction; and the material cost is high; there are risks such as leaking pipes and blocked pipes.

Embodiment 2

[0041] refer to Figure 4 A method for using the above mass concrete temperature control device provided in this embodiment includes the following steps:

[0042] The first step is to initialize the central controller 2;

[0043] In the second step, the central controller 2 collects the signals of the temperature sensor 3 of the concrete inner layer 61 and the concrete outer layer 62;

[0044] In the third step, the central controller 2 compares the temperature of the concrete inner layer 61 and the concrete outer layer 62. If the temperature difference is less than the temperature difference setting value, then stop supplying power to the bimetal structure 1 and return to the second step. If the temperature difference is greater than the temperature difference setting value, enter the fourth step;

[0045] In the fourth step, the central controller 2 supplies power to the bimetal structure 1, lowers the temperature of the inner concrete layer 61, raises the temperature of t...

Abstract

The invention provides a mass concrete temperature control device and a using method thereof so as to improve concrete pouring quality. The mass concrete temperature control device comprises two bimetallic strip structures, temperature sensors and a central controller, wherein the two bimetallic strip structures are separately buried in a concrete inner layer and a concrete outer layer; and the temperature sensors are separately close to the bimetallic strip structures. When the temperature of the concrete inner layer is over high and the temperature of the concrete outer layer is over low, the central controller can supply power for the bimetallic strip structures, by a Peltier effect, the temperature of the bimetallic strip structure which is buried in the concrete inner layer can be reduced, the temperature of the bimetallic strip structure which is buried in the concrete outer layer can be increased so as to ensure that the difference between the internal temperature and the external temperature is not over large in an integral concrete pouring process, and the purpose of improving concrete pouring quality by preventing stress or tensile force which damages a concrete structurefrom being generated in concrete.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a large-volume concrete temperature control device. Background technique [0002] During the concrete pouring process, the internal heat of the concrete is difficult to dissipate, and the external surface heat dissipates quickly. The process of internal and external thermal expansion and contraction will correspondingly generate tensile stress on the concrete surface. When the temperature difference is large to a certain extent, when the tensile stress on the concrete surface exceeds the ultimate tensile strength of the concrete at that time, harmful cracks will occur on the concrete surface, and sometimes even run through the cracks. [0003] In order to avoid the above situation, the existing concrete temperature control mainly starts from the following aspects. Before pouring, it mainly starts from the configuration of concrete, the selection of raw m...
