Temperature control device for use in civil engineering temperature stress measurement

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of temperature control of structural engineering glass curtain walls in civil engineering, in particular to the measurement and research of temperature stress of energy-saving curtain wall glass panels, and in particular to a temperature control device for measuring temperature stress in civil engineering. Background technique [0002] Ordinary single-layer glass curtain wall has poor thermal insulation effect. In recent years, various energy-saving glass has been applied to curtain wall. However, the application of energy-saving glass has greatly changed the temperature field of the curtain wall while achieving a good thermal insulation effect. The temperature stress research of the curtain wall is mostly carried out under the condition that the overall temperature of the glass changes uniformly, and the research on the mechanical performance of energy-saving glass, such as insulating glass, etc. under the ...
