Embodiment 1

[0040] See attached figure 1 , A device for detecting thermal insulation performance of building doors and windows includes a test chamber 100, a hot box 110 and a cold box 120 installed in the test chamber 100 and arranged in close contact with each other. Wherein, a detection opening and a test piece frame 130 installed at the detection opening are provided between the hot box 110 and the cold box 120.

[0041] The hot box 110 is also provided with an electric heater 111 for increasing the temperature in the hot box 110, and the electric heater 111 is installed on the wall at the bottom of the test frame 130. The cold box 120 is provided with an air baffle 121 directly opposite to the specimen frame 130 and a fan 122 installed at the bottom of the air baffle 121 and connected to both sides of the air baffle 121. The level of the fan 122 is lower than that of the specimen frame 130. Horizontal height. The cold box 120 is further provided with an evaporator 123 of the refrigerat...

Embodiment 2

[0053] A method for detecting thermal insulation performance of building doors and windows, using the above-mentioned thermal insulation performance testing device for building doors and windows, includes the following steps:

[0054] S100. Install the pre-assembled inner frame 220 corresponding to the door and window test piece to the pre-assembled outer frame 210, and place the first supporting bar 250 and the second supporting bar on one side of the pre-assembled outer frame 210 and the pre-assembled inner frame 220 260 for installation, and then fill the first filler blocks 230 on both sides of the pre-assembled inner frame 220, and fill the second filler blocks 240 on the top of the pre-assembled inner frame 220 and the bottom of the pre-assembled outer frame 210, and then install Pre-assemble the outer frame 210 and the first support bar 250 and the second support bar 260 on the other side of the pre-assembled inner frame 220, and use polyurethane foam filler to pre-assemble...

Abstract

The invention discloses a device and method for detecting heat insulating properties of building doors and windows, and solves the problem that the mounting efficiency of test pieces of doors and windows at the present stage is low. The main points of the technical scheme are that the device for detecting the heat insulating properties of the building doors and windows comprises a test room, and ahot box and a cold box which are mounted in the test room and adhered to each other; a detecting opening is formed between the hot box and the cold box, and a test piece frame is mounted at the detecting opening; the device for detecting the heat insulating properties of the building doors and windows is also provided with a test piece pre-assembled assembly; the test piece pre-assembled assemblycomprises a pre-assembled outer frame which is adhered to the test piece frame, a pre-assembled inner frame which is adhered to the test pieces of the doors and windows, a supporting piece which is supported between the pre-assembled outer frame and the pre-assembled inner frame, and a filling piece which fills between the pre-assembled inner frame and the pre-assembled outer frame; after the adoption of the device for detecting the heat insulating properties of the building doors and windows, the mounting efficiency of the test pieces of the doors and windows can be improved, so that the detecting efficiency of the heat insulating properties of the overall test pieces of the doors and the windows can be improved.

Description

Technical field [0001] The invention belongs to the technical field of building detection, and particularly relates to a detection device and a detection method for the insulation performance of building doors and windows. Background technique [0002] The thermal insulation performance test of building doors and windows is a test to measure the heat transfer coefficient of building doors and windows, which is generally carried out in a professional building door and window thermal insulation performance testing device. The thermal insulation performance testing device of building doors and windows generally consists of five parts: hot box, cold box, test frame, humidity control system and environmental space. The test frame is installed in the opening between the hot box and the cold box. [0003] Since the size of the test piece frame and the size of the door and window test piece are not matched one by one, the steps to install the door and window test piece to the test piece fr...
