Thermal cycle performance detection device of building curtain wall

Abstract

The invention relates to a thermal cycle performance detection device of a building curtain wall. The thermal cycle performance detection device comprises a spliced heat preservation box body, the thermal cycle performance detection device is characterized in that the detection device further comprises at least one outdoor environment simulation control box and an indoor environment simulation control box, the heat preservation box body is a box body having four side faces and one bottom surface, and the lost top face of the heat preservation box body is hermetically docked with one side faceof a curtain wall test piece; and the outdoor environment simulation control box is hermetically docked with the bottom surface of the heat preservation box body, and the indoor environment simulationcontrol box communicates with a static pressure box body on the other side face of the curtain wall test piece through a pipeline. The heat preservation box body is made of a double-sided polyurethane color plate, the double-sided polyurethane color plate comprises foamed polyurethane, hard rubber and color plates, the color plates are arranged on both sides of the foamed polyurethane, and the hard rubber is sandwiched between the foamed polyurethane and the color plates; and a raw material for preparing the foamed polyurethane is a composite foaming agent, and the hard rubber contains magnesium oxide.

Description

technical field [0001] The invention belongs to the technical field of curtain wall detection equipment, and in particular relates to thermal cycle performance detection equipment of building curtain walls. Background technique [0002] In recent years, the country has paid more and more attention to building energy conservation. The building enclosure structure, especially the building curtain wall, has excellent thermal insulation and thermal insulation performance. an important parameter. At present, my country's testing of thermal insulation performance is mainly based on thermal cycle testing of curtain walls. [0003] Patent CN201520339590.0 discloses a building curtain wall thermal cycle test device, including a curtain wall specimen, a support structure for supporting the curtain wall specimen, a heating structure, a cooling structure, and a testing structure; the heating structure includes several Lighting lamps, lamp holders for supporting the lighting lamps, and...

Problems solved by technology

However, due to the need to install various constant temperature and humidity equipment and control devices inside the overall testing equipment, the volume of the overall testing equipment is still relatively large. When testing large curtain wall specimens, the equipment is still relatively cumbersome, with low flexibility and low efficiency. Low, not conducive to large-scale promotion and application

In addition, the material of the detection box is generally made of double-sided polyurethane color steel plate. In order to improve the thermal insulation performance of the detection box and improve the detection accuracy, the polyurethane color steel plate with a larger bulk density is the first choice. However, this will increase the weight of the detection box. Not conducive to installation and movement
