Temperature control device for use in civil engineering temperature stress measurement

The invention discloses a temperature control device for use in civil engineering temperature stress measurement, which belongs to the technical field of glass curtain wall temperature control. The temperature control device comprises a heating box and a cooling box, which are independent of each other and are positioned on two sides of a measured object, wherein both the heating box and the cooling box have an open double-layer box body, and thermal-insulation foam is filled between the inner-layer box bodies and the out-layer box bodies; the bottom surfaces of the inner-layer box bodies of the heating box and the cooling box are both fixed with a heating plate and iron plates are arranged on the outer side of the heating plates; cooling pipes are arranged between the inner-layer box body and the iron plate of the cooling box and is provided with holes for charging liquid nitrogen for cooling; and thermocouples are arranged in the box bodies of the heating box and the cooling box, the heating box is provided with openings, and fans are arranged in the box bodies on the outer sides of the iron plates. The whole device is well sealed, the temperature fields are uniform, and the influence of various side effects caused by temperature on a test piece is slight. The temperature control is flexible and simple and different temperature fields are realizes conveniently on two sides of the test piece.
