Description
Technical Field
[0001] This invention relates to the field of building materials testing technology, specifically a method for testing the thermal insulation performance of building curtain wall materials. Background Technology
[0002] With the development of new building materials, the requirements for thermal insulation performance in new buildings are becoming increasingly stringent. The heat exchange within the walls accounts for a large proportion of the overall heat exchange in a building, and the curtain wall is a crucial component of the building facade. Its thermal insulation performance directly affects the energy efficiency of the entire building, and is also related to the comfort and health of its occupants. Therefore, evaluating the thermal insulation performance of curtain wall materials is of great significance to building engineering.
[0003] A search revealed a Chinese patent disclosure for a device for testing the thermal insulation performance of building exterior walls (authorization announcement number CN210005467U). This patented technology utilizes an outer and inner insulation shell in conjunction with a temperature sensing module and a heating module to form a constant temperature control system. This ensures that the devices located on both sides of the wall are operating within a constant temperature range, reducing interference from external environmental factors. However, while some thermal insulation performance testing devices exist on the market, they typically require multiple tests in indoor and outdoor environments, raising concerns about the accuracy and reliability of the test results. Furthermore, existing devices are not suitable for testing the thermal insulation performance of curtain walls of different specifications. Therefore, this invention provides a method for testing the thermal insulation performance of building curtain wall materials to address the problems mentioned in the background. Summary of the Invention
[0004] This invention addresses the technical problems existing in the prior art by providing a method for testing the thermal insulation performance of building curtain wall materials. This solves the problem that existing devices usually require multiple tests in indoor and outdoor environments, and the accuracy and reliability of the test results cannot be guaranteed. Furthermore, existing building exterior wall thermal insulation performance testing devices cannot adapt to the thermal insulation performance testing of building curtain walls of different specifications.
[0005] The technical solution of this invention to solve the above-mentioned technical problems is as follows: a method for testing the thermal insulation performance of building curtain wall materials, comprising the following steps:
[0006] S1. Fix the position of the building curtain wall material;
[0007] S2. Provide multi-point support for building curtain wall materials to test their fracture resistance.
[0008] S3. Conduct a water spray test on the building curtain wall material to test its water absorption.
[0009] The above steps employ the following building curtain wall material thermal insulation performance testing device, which includes a box, a workbench, a clamping mechanism, and a cooling mechanism. Support legs are provided at the four corners of the workbench, and a box is provided on one side of the workbench. A bolt-driven clamping mechanism is provided on the workbench, on which building curtain wall material is installed. A cooling mechanism is provided inside the box, and heating and cooling plates are respectively embedded on one side of the box. The heating plates and the cooling mechanism are compatible with each other.
[0010] The beneficial effects of this invention are:
[0011] 1. When the clamping plate is tightened with the building curtain wall material, the position of the building curtain wall material is fixed by the limiting groove of the limiting rod, ensuring full contact between the building curtain wall material and the temperature-conducting aluminum profile. When the building curtain wall material undergoes thermal expansion and contraction, the clamping plate can move horizontally along the limiting rod due to the action of the spring, ensuring that the position of the building curtain wall material will not shift due to temperature changes. The clamping plate provides stable fixed support for the building curtain wall material, ensuring that the building curtain wall material will not move or deform during the test, thereby ensuring the accuracy and reliability of the test data. The clamping force between the clamping plate and the building curtain wall material can be controlled by adjusting the bolts, allowing the clamping plate to be evenly clamped. Applying pressure to the building curtain wall material helps prevent deviations in test results. The clamping plate not only secures the material but also maintains its flatness, ensuring full contact between the material and the thermally conductive aluminum profile, thus guaranteeing accurate test results. Therefore, the clamping plate plays a crucial role in testing. Besides providing fixed support, uniform force distribution, and maintaining flatness, it also prevents abnormal situations during testing, ensuring safety and stability. Furthermore, the clamping plate allows adjustment of the building curtain wall material's position within it, and the first and second temperature sensors can detect the temperature at multiple points on the exterior of the material.
[0012] 2. The oscillation of the nozzle can maximize testing efficiency. By reasonably controlling the position of the nozzle, the amount of cooling water and testing time required during testing can be reduced, thereby lowering testing costs. Different building curtain wall materials have different thermal insulation performance at different temperatures. By controlling the position of the nozzle, different testing conditions can be met, expanding the testing range and providing more comprehensive technical support for building energy conservation. In addition, a third and fourth temperature sensor are respectively installed in the connector and connected to a microcontroller. The microcontroller receives the temperature data collected by the sensor, processes the data through an algorithm, and then displays it on the screen so that users can understand the temperature changes during the test. The core controller of the entire system uses an STM microcontroller, which can ensure the system's high efficiency, stability, and reliability. The device detects the external temperature of the building curtain wall material through the first and second temperature sensors, which is the indoor temperature. The heating and cooling elements can simulate the contact temperature of one side of the building curtain wall material under different external conditions. The third and fourth temperature sensors detect the temperature generated by the heating and cooling elements, thus detecting its thermal insulation performance.
[0013] 3. The telescopic cylinder is controlled to operate, driving the rack to move vertically. The rack meshes with the incomplete gear, thereby controlling the position of the support rod and allowing it to rotate within a certain range. This allows the thrust rod to slide up and down along the surface of the building curtain wall material, providing multi-point support to the material. Cooling water is sprayed through nozzles to test the water absorption of the curtain wall material, and the multi-point support provided by the thrust rod tests the wall's resistance to breakage during water absorption.
[0014] 4. During water spraying, the nozzle can push the sliding rod vertically via the rack and pinion mechanism. This, in turn, drives the moving rod vertically via the first and second connecting rods, causing the nozzle to deflect and swing vertically. This increases the spray range and ensures accurate water absorption testing of the building curtain wall material. A guide plate guides the water flow more linearly, ensuring more precise spraying points. Furthermore, a high-pressure fan pressurizes the atomized water flow, ensuring accurate water delivery to and from the building curtain wall material, facilitating rapid water absorption and guaranteeing the accuracy of the water absorption test.
[0015] 5. The device detects the external temperature of the building curtain wall material through a first temperature sensor and a second temperature sensor. The external temperature of the building curtain wall material is the indoor temperature. The heating element and cooling element can simulate the contact temperature of one side of the building curtain wall material under different external conditions. The third temperature sensor and a fourth temperature sensor detect the temperature generated by the heating element and cooling element, and observe their temperature ratio to judge the thermal insulation performance of the building curtain wall material.
[0016] Based on the above technical solution, the present invention can be further improved as follows.
[0017] Furthermore, the clamping mechanism includes a transmission groove, a rotating shaft, a clamping plate, a limiting rod, a threaded rod, an adjusting bolt, a spring, a limiting block, a limiting groove, and a fixing component. The worktable has two sets of symmetrically arranged transmission grooves on one side, and a rotating shaft is installed in the transmission groove. A clamping plate is installed on the rotating shaft, and a fixing block is installed in the middle of the transmission groove. A limiting block is installed in the middle of the fixing block. Limiting rods are movably connected to the clamping plates on both sides. A limiting groove is opened in the middle of the limiting rod, and the limiting block is located on the limiting groove.
[0018] Furthermore, a fixing member is provided on one side of the limiting rod, and the surface of the limiting rod away from the fixing member has a threaded structure. An adjusting bolt is threadedly connected to one side of the limiting rod, and a spring is sleeved on the limiting rod between the clamping plates and the fixing block on both sides.
[0019] Furthermore, the clamping plate and the building curtain wall material are mutually compatible, and a first temperature sensor and a second temperature sensor are respectively provided on one side of the two clamping plates.
[0020] The beneficial effect of adopting the above-mentioned further solution is that the clamping mechanism can clamp and fix the building curtain wall material, and in conjunction with the first temperature sensor and the second temperature sensor, the surface temperature change of the material can be detected in a timely manner, which can realize the testing and monitoring of the building curtain wall material. The various components of the clamping mechanism cooperate with each other, which not only ensures the accuracy and real-time nature of the test data, but also improves work efficiency and safety.

A support rod is installed on the other side of the rotating disk, and two sets of thrust rods with an upward and downward inclined angle are provided at the outer end of the support rod.
[0023] The housing is also equipped with a support frame, on which two sets of swing rods are hinged. Spray heads are mounted on the swing rods. A second water pump is installed inside the support frame. The output end of the second water pump is connected to the spray head via a delivery pipe.

[0024] Furthermore, the box body is symmetrically provided with connectors on one side, and temperature-conducting aluminum profiles are movably connected to the connectors. The temperature-conducting aluminum profiles are detachable devices and vary in size.
[0025] Furthermore, a third temperature sensor and a fourth temperature sensor are embedded in the housing between the heating element, the cooling element, and the connector.

[0027] Furthermore, the thermally conductive aluminum profile is mated to one side of the building curtain wall material.
[0028] The beneficial effects of adopting the above-mentioned further solution are that the temperature-conducting aluminum profile, connectors, and corresponding temperature sensors installed in the cabinet have excellent effects.

[0054] In this embodiment, the housing 1 is also provided with a support frame 16. Two sets of swing rods 161 are hinged on the support frame 16.

[0058] The thermally conductive aluminum profile 9 and one side surface of the building curtain wall material 7 are mutually compatible.
[0059] In summary, the beneficial effects of this invention are specifically reflected in the following aspects: First, the building curtain wall material 7 to be tested is placed between the clamping plates 303, and the clamping force between the clamping plates 303 and the building curtain wall material 7 is controlled by adjusting the bolts 306. Second, when the clamping plates 303 are clamped to the building curtain wall material 7, the position of the building curtain wall material 7 is fixed by the limiting groove 309 of the limiting rod 304, ensuring that the building curtain wall material 7 is in full contact with the temperature-conducting aluminum profile 9. Furthermore, when the building curtain wall material 7 undergoes thermal expansion and contraction, due to the action of the spring 307, the clamping plates 303 can move horizontally along the limiting rod 304 to ensure that the position of the building curtain wall material 7 will not shift due to temperature changes. The clamping plates 303 provide stable fixed support for the building curtain wall material 7, ensuring that the building curtain wall material 7 will not move or deform during the test, thereby ensuring the accuracy and reliability of the test data. By adjusting the bolts 306 to control the clamping force between the clamping plates 303 and the building curtain wall material 7, the clamping plates 303 can evenly clamp the building curtain wall material. Pressure is applied to the material 7 to avoid deviations in the test results. The clamping plate 303 not only fixes the building curtain wall material 7, but also maintains the flatness of the building curtain wall material 7, ensuring full contact between the building curtain wall material 7 and the thermally conductive aluminum profile 9, thereby ensuring the accuracy of the test results. Therefore, the clamping plate 303 plays an important role in the test. In addition to fixing and supporting, uniformly distributing force and maintaining flatness, it can also prevent abnormal situations from occurring during the test, ensuring the safety and stability of the test process. The clamping plate 303 can also be used to adjust the position of the building curtain wall material 7 on the clamping plate 303. The temperature of multiple points on the outside of the building curtain wall material 7 can be detected by the first temperature sensor 8 and the second temperature sensor 11. Cooling water enters the cooling pool 503 of the mounting groove 501 in the housing 1 through the first water pump 506, and then is sprayed onto the heating element 13 through the nozzle 162 to cool the heating element 13. At the same time, the components such as the cooling pool 503 and the cooling inclined plate 502 can ensure that the temperature of the cooling water does not become too high. An incomplete gear 511 is provided on one side of the nozzle 162. The telescopic cylinder 509 is controlled to operate, and the telescopic cylinder 509 can drive the rack 510 to move vertically. The rack 510 and the incomplete gear 511 mesh with each other, thereby controlling the position of the support rod 514, so that the support rod 514 can rotate within a range of 120 degrees, allowing the thrust rod 515 to slide up and down along the surface of the building curtain wall material 7 to provide multi-point support for the building curtain wall material 7. The water absorption of the building curtain wall material 7 is tested by spraying cooling water through the nozzle 162, and the multi-point support of the building curtain wall material 7 by the thrust rod 515 is used to test the anti-crack effect of the wall during the water absorption process.
[0060] In addition, during the water spraying process, the nozzle 162 can push the sliding rod 163 to slide vertically through the rack 510, thereby driving the moving rod 161 to swing vertically through the first connecting rod 164 and the second connecting rod 165, which in turn causes the nozzle 162 to deflect and swing vertically, thereby increasing the spray range and ensuring large-area water absorption testing of the building curtain wall material 7. The guide plate 166 guides the water flow to be more linear, ensuring more precise spraying points. In addition, the high-pressure fan 167 pressurizes the atomized water flow to ensure that the water flow accurately enters and exits the building curtain wall material 7, so as to meet the needs of the building curtain wall material 7 to quickly absorb water and ensure the accuracy of water absorption testing.
[0061] It should be noted that the oscillation of the nozzle 162 can maximize testing efficiency. By reasonably controlling the position of the nozzle 162, the amount of cooling water and testing time required during testing can be reduced, thereby lowering testing costs. Different building curtain wall materials 7 have varying thermal insulation performance at different temperatures. By controlling the position of the nozzle 162, different testing conditions can be met, expanding the testing range and providing more comprehensive technical support for building energy conservation. Furthermore, a third temperature sensor 12 and a fourth temperature sensor 14 are respectively installed within the connector 10 and connected to a microcontroller. The microcontroller receives the temperature data collected by the sensors, processes the data using an algorithm, and then... The temperature is then displayed on screen 6 so that users can understand the temperature changes during the test. The core controller of the entire system uses an STM32 microcontroller, which can ensure the system's high efficiency, stability and reliability. The device detects the external temperature of the building curtain wall material 7 through the first temperature sensor 8 and the second temperature sensor 11. The external temperature of the building curtain wall material 7 is the indoor temperature. The heating element 13 and the cooling element 15 can simulate the contact temperature of one side of the building curtain wall material 7 under different external conditions. The third temperature sensor 12 and the fourth temperature sensor 14 detect the temperature generated by the heating element 13 and the cooling element 15, and detect its thermal insulation performance.
