Abstract

The invention discloses a building external wall thermal insulation performance detection device and a detection method, relates to the technical field of building thermal insulation detection, and solves the problems that an existing device is inconvenient to carry out multiple times of test detection on different positions of two sides of a wall body, and an average thermal insulation performance value of the wall body is inconvenient to obtain. The invention discloses a building external wall thermal insulation performance detection device and detection method. The right side of the top surface of the parallel frame is fixedly connected with a control detection platform; the left side of the top surface of the parallel frame is fixedly connected with a screw jack; a deflection angle control structure is arranged at the top of the screw jack; after the position of the heat transfer cross detection mechanism at the front end on the outer side of the wall is changed by holding the grip to perform angle deflection on the rotating plate, automatic limiting is performed to fix the angle of the detection mechanism, the heat transfer cross detection mechanism is repeatedly moved to perform multiple times of movement detection on the outer side of the wall, and after average calculation is performed on multiple groups of experimental data, the detection accuracy is improved. The average thermal insulation performance value of the whole outer wall can be obtained.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation detection, in particular to a detection device and a detection method for thermal insulation performance of external walls of buildings. Background technique [0002] External thermal insulation of external walls is a thermal insulation method in which the thermal insulation layer is placed outside the main wall material, because it can reduce the point influence and protect the main wall material from the temperature deformation stress. It is the most widely used thermal insulation method. After completion, it is necessary to test the thermal insulation performance of the outer wall, and the existing device and method are inconvenient to test the thermal conduction strength on both sides of the wall. [0003] After searching, for example, the patent No. CN110133040A discloses a thermal insulation performance detection device for building exterior walls, which belongs to the fi...

Problems solved by technology

[0008] The object of the present invention is to provide a detection device and detection method for the thermal insulation performance of building exterior walls, to solve the problem that the traditional detection devices for thermal insulation performance of building exterior walls proposed in the above background technology generally use the hot box method, and generally do not set up to facilitate the two sides of the wall. The structure of testing the heat conduction strength on the side is not convenient for multiple tests and tests on different positions of the wall outside the window, and it is not convenient to calculate the average thermal insulation performance value of the wall after averaging multiple sets of experimental data, and it cannot reduce the impact of the temperature difference between the inside and outside of the building. The problem of interference with the numerical accuracy of thermal insulation performance on both sides of the wall
