[0002] Thermal bridging is a term in the building materials field, traditionally categorized as either cold bridges or thermal bridges. These are different ways of describing the same phenomenon, used in different regions of China. It refers to areas within a building where heat is concentrated due to differences in heat transfer coefficients.

The concrete slab and concrete cylinder blanks are cured. After curing, the exchange pipes are removed from the sleeve, thus producing the thermal bridge device. When the performance of the thermal bridge device needs to be verified, the lifting rope is passed through the through holes of ear I and ear II. The cover is lifted by lifting machinery and removed from the upper open body of the box.

The hot air blower and rotating table are in working condition. The rotating table drives the hot air blower to rotate, and the hot air is released within the heating zone. High-temperature air is used to pick up the temperature signal in the heating zone through a lower temperature sensor. The high-temperature air in the heating zone is then used to conduct the temperature signal in the measurement zone through a thermal bridge device. The upper temperature sensor picks up the temperature signal in the measurement zone. Heating is carried out for a specified time. The difference between the temperature signal in the measurement zone and the temperature signal in the heating zone is used as a performance verification parameter for the thermal bridge device.

The cover is removed from the upper opening of the box, and the inner end of the clamping screw is rotated in the opposite direction in the receiving hole. The clamping screw is then separated from the receiving hole, and the pressure plate, clamping screw, thermal bridge device, and test sample are removed from the box.

[0107] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0108] A method for verifying the performance of thermal bridges in exchange pipeline supports includes the following steps: cutting the middle of a grid plate 20 to obtain an installation hole; placing a raw material sheet of a grid cylinder 30 into the installation hole of the grid plate 20, so that the raw material sheet of the grid cylinder 30 is in a rolled state; performing heat fusion connection between the middle of the peripheral side of the grid cylinder 30 and the inner wall of the installation hole of the grid plate 20; performing heat fusion connection on the mating end faces of the raw material sheet of the grid cylinder 30; and winding the raw material sheet of the sleeve 40 onto the exchange pipeline, with the raw material sheet of the sleeve 40 being wound on the outer side of the sleeve. An adhesive is applied, and the exchange pipe with the sleeve 40 is placed into the grid cylinder 30, so that the outer side of the sleeve 40 is bonded to the inner wall of the grid cylinder 30. A concrete slab 10 blank is formed on the end face of the grid sheet 20 using 3D printing, and a concrete cylinder 50 blank is formed on the peripheral side of the grid cylinder 30. Both the concrete slab 10 and concrete cylinder 50 blanks are cured. After curing, the exchange pipe is removed from the sleeve 40, thus completing the thermal bridge device. When the performance of the thermal bridge device needs to be verified, a lifting rope is passed through the through holes of ear seat I 62 and ear seat II 63. Using lifting machinery, the cover 61 is lifted and removed from the upper open end of the housing 11. The exchange pipe is installed in the sleeve 40, and asbestos is inserted into the exchange pipe to obtain a thermal bridge device test sample. The thermal bridge device test sample is placed in the housing 1. The lower end face edge of the concrete slab 10 is placed on the upper end face of the lower ring 12. The inner end of the clamping screw 91 is placed in the receiving groove 98, causing the inner end of the clamping screw 91 to rotate within the receiving hole 15, thus allowing the plate to... 99 moves downward, causing the inner end face of the horizontal part of plate 99 to act on the edge of the upper end face of concrete slab 10, causing the inner end of clamping screw 91 to continue rotating in receiving hole 15, causing the flange of clamping screw 91 to act on the outer end face of the vertical part of plate 99. Using lifting machinery, cover 61 is placed into the upper open body of box 11, and lifting ropes are removed from the through holes of ear seat I 62 and ear seat II 63, thereby installing the thermal bridge device test sample in box shell 1. A heating zone is formed between the bottom wall of box shell 1 and the thermal bridge device test sample, and a measurement zone is formed between cover 6 and the thermal bridge device test sample. The hot air blower 2 and the rotating table 3 are put into operation. The rotating table 3 drives the hot air blower 2 to rotate, releasing high-temperature air into the heating zone. The lower temperature sensor 7 picks up the temperature signal in the heating zone. The high-temperature air in the heating zone passes through the thermal bridge device to test the sample conduction in the measurement zone. The upper temperature sensor 8 picks up the temperature signal in the measurement zone. Heating is performed for a specified time. The difference between the temperature signal in the measurement zone and the temperature signal in the heating zone is used as a performance verification parameter for the thermal bridge device. After verifying the performance of the thermal bridge device, the hot air blower 2 and the rotating table 3 are put into a non-working state. The cover 61 is removed from the upper open body of the box 11, and the inner end of the clamping screw 91 is rotated in the opposite direction in the receiving hole 15. The clamping screw 91 is separated from the receiving hole 15, and the pressure plate 9, the clamping screw 91 and the thermal bridge device test sample are taken out of the box 1.

[0109] In verifying this invention, the inventors abandoned the existing technical feature of filling the space between the exchange pipe and the installation channel located on the building body with asbestos blocks. They first proposed a technical feature of a cable tray with a flat installation surface, resulting in the first unexpected technical effect: achieving a flat installation connection with the building body, improving the support strength of the exchange pipe. The second unexpected technical effect: enabling the installation of the exchange pipe through concrete slab 10, grating 20, grating cylinder 30, and concrete cylinder 50, increasing the broad connection surface with the building and improving the performance of the thermal bridge. The third unexpected technical effect: achieving heat insulation treatment on the exchange pipe through sleeve 40, improving the installation stability of the exchange pipe. The fourth unexpected technical effect: enabling temperature difference characterization of the thermal bridge device's performance through the housing 1, hot air blower 2, cover 6, lower temperature sensor 7, and upper temperature sensor 8, improving the performance of the thermal bridge device. The performance verification accuracy yielded a fifth unexpected technical effect: the high-temperature air in the housing 1 was mixed and distributed through the rotating table 3, the swaying bar 4, and the pull rope 5, improving the heat conduction performance of the thermal bridge device. A sixth unexpected technical effect was achieved: the thermal bridge device was pressed and installed in the housing 1 through the pressure plate 9 and the clamping screw 91, improving the sealing performance of the contact surface between the thermal bridge device and the housing 1. A seventh unexpected technical effect was achieved: the grid plates 20 and grid cylinders 30 served as the skeleton of the thermal bridge device, eliminating the difference in heat conduction performance between the thermal bridge device and the concrete slab 10 and concrete cylinder 50, maintaining the heat conduction performance of the thermal bridge device. An eighth unexpected technical effect was achieved: instead of filling the space between the exchange pipe and the installation hole on the building body with asbestos blocks, a frame matching the building was used to install the exchange pipe, expanding the spatial structure of the thermal bridge device and optimizing the thermal bridge structure between the exchange pipe and the building.

[0110] In a second embodiment of the present invention, the concrete slab 10, the concrete cylinder 50, the grid sheet 20 and the grid cylinder 30 are interconnected in a manner that uses a mounting channel bridge with a flat surface.

[0111] In this embodiment, the grid plate 20 and grid cylinder 30 are connected to the concrete slab 10 and concrete cylinder 50 in a manner that creates a thermal bridge skeleton.

[0112] In this embodiment, a first accessory device is also included, and the first accessory device is configured as a sleeve 40.

[0113] The second embodiment of the present invention is based on the first embodiment. In the second embodiment of the present invention, the housing 1, the cover 6, the upper temperature sensor 8, the hot air blower 2 and the lower temperature sensor 7 are interconnected in a manner that identifies the temperature difference of the heat penetrating the thermal bridge device.

[0116] In this embodiment, a second accessory device is also included, and the second accessory device is configured to include a pressure plate 9 and a clamping screw 91.

[0117] The second embodiment of the present invention is based on the first embodiment. In the second embodiment of the present invention, the steps are as follows: the housing 1, the cover 6 and the hot air blower 2 are used to build an isolation zone for the thermal bridge device, and the upper temperature sensor 8 and the lower temperature sensor 7 are used to pick up the temperature signal in the housing 1, so as to identify the temperature difference of the heat penetrating the thermal bridge device.

[0118] The second embodiment of the present invention is based on the first embodiment. This invention has the following characteristics: 1. By designing concrete slab 10, concrete cylinder 50, grid sheet 20 and grid cylinder 30, the shell of the thermal bridge is realized through concrete slab 10 and concrete cylinder 50, and the skeleton of the thermal bridge is realized through grid sheet 20 and grid cylinder 30. This realizes the installation channel cable tray with flat surface, which solves the technical problem of filling asbestos blocks between the exchange pipe and the installation channel located on the building body, thus improving the installation performance between the exchange pipe and the building body.

[0119] 2. Due to the design of the sleeve 40, a pad connection is realized between the exchange pipe and the grid cylinder 30.

[0120] 3. By designing a housing 1, a cover 6, an upper temperature sensor 8, a hot air blower 2, and a lower temperature sensor 7, the housing 1, cover 6, and hot air blower 2 enable the internal isolation zone of the thermal bridge device. The upper and lower temperature sensors 8 and 7 enable the acquisition of temperature signals within the housing 1, allowing for the identification of temperature differences in the heat penetrating the thermal bridge device. This solves the technical problem of filling asbestos blocks between the exchange pipe and the installation hole located on the building structure, thus improving the verification effect of the installation performance between the exchange pipe and the building structure.

[0121] 4. Due to the design of the rotating platform 3, the swaying bar 4 and the pull rope 5, the high temperature air in the box shell 1 is evenly distributed.

[0122] 5. Due to the design of the pressure plate 9 and the clamping screw 91, the thermal bridge device can be installed and connected in the housing 1.

[0123] 6.

The experiment shows that the technical feature of this numerical range has achieved very good technical effect.

Due to the design of the technical features of this invention, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this invention are at least 1.7 times that of existing performance indicators, and the invention has been evaluated to have good market value.
