Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] See appendix Figures 1 to 4 This is the main structure of a water tightness performance testing platform for building curtain wall unit panels. The platform includes a tilting worktable 10 and a water spray rack 20. The tilting worktable 10 includes a support frame 11 and a tilting table surface 12. One end of the tilting table surface 12 is hinged to the support frame 11. The tilting table surface 12 is placed horizontally on the support frame 11 and can be tilted to be perpendicular to the ground. Specifically, a hydraulic cylinder 30 is mounted on the support frame 11. The piston rod 31 of the hydraulic cylinder 30 is rotatably connected to the tilting table surface 12. By lifting the piston rod 31, the tilting table surface 12 can be tilted to be perpendicular to the ground, and by retracting the piston rod 31, the tilting table surface 12 can be placed horizontally on the support frame 11.

[0020] Multiple specimen fixing members 40 are installed on the flipping table 12, with both ends of the fixing members being bolted to the flipping table 12. In this embodiment, two standard square steel bars with specifications of 60mm×60mm×3800mm are used as specimen fixing members 40. They are laterally anchored along both sides of the unit plate 50, and the square steel bars are rigidly connected to the flipping table 12 by bolt assemblies to form an anti-tipping support structure, ensuring that the unit plate 50 remains vertically stable during the test. A ladder 13 is also provided on one side of the flipping table 12.

[0021] A water collection hopper 32 is placed below the rotating platform 12, which is in a vertical position. The bottom of the water collection hopper 32 is connected to the inlet of a self-priming water pump 33 via a water pipe. The water spray rack 20 includes a vertical section 21 and a base 22. In use, the vertical section 21 of the water spray rack 20 faces the rotating platform 12. The vertical section 21 is connected to one end of the base 22 and has an array of spray nozzles 23. A water collection tank 25 is installed on the base 22. The spray nozzles 23 are connected to the outlet of a booster pump 24 via a water pipe. The inlet of the booster pump 24 is connected to the water collection tank 25 via a water pipe. The outlet of the booster pump 24 is also equipped with a flow meter 26. The outlet of the self-priming water pump 33 is connected to the water collection tank 25 via a telescopic water pipe 27. Sliding wheels 28 are installed at the four corners of the base 22. A water level brake controller 29 is installed inside the water collection hopper 32, and the water level brake controller 29 is coupled to a self-priming water pump 33.

[0022] The water collection tank 25, consisting of a one-ton water tank, is placed on the base 22 of the spray frame 20. A booster pump 24 pumps water to the spray nozzles 23. A water collection hopper 32 located beneath the tilting platform 12 collects the spray water. When the water level reaches the upper limit of the collection tank, the self-priming pump 33 automatically starts operating; when the water level falls below the lower limit, the self-priming pump 33 stops working. The spray water can be reused, achieving energy savings.

[0023] A negative pressure fan 60 is installed on one side of the support frame 11, and the air intake of the negative pressure fan 60 is connected to an air intake duct 61. A negative pressure gauge 62 for connection to the unit panel 50 is also installed on the flip platform 12. The testing platform also includes a control cabinet 70 and a hydraulic station 71. The control cabinet 70 is electrically connected to the negative pressure fan 60, the negative pressure gauge 62, the self-priming water pump 33, and the booster pump 24. The hydraulic station 71 is used to drive the hydraulic cylinder 30.

[0024] The working principle of this utility model: The unit plate 50 to be tested is precisely loaded onto the flipping table 12 using a forklift, and then horizontally anchored along both sides of the unit plate 50 using the specimen fixing piece 40. The suction duct 61 and the negative pressure gauge 62 are connected to the unit plate 50.

[0025] High-quality, high-strength sealing tape is used to seal the entire perimeter of the contact surface between the unit panel 50 and the flip table 12. By overlapping and wrapping, it is ensured that there is no risk of leakage at the joint. The tape width is not less than 50mm, and the edges must be pressed firmly.

[0026] Start the hydraulic cylinder 30 to push the tilting platform 12 at a uniform speed of 0.5 m / min, so that the tilting platform 12 is vertically erected to an angle of 90° ± 0.5° with the ground; simultaneously start the booster pump 24 to activate the spray system, with a water flow rate of 3 L / (m³). 2 A flow rate of ·min) is used to spray the entire outer surface of the unit plate 50.

[0027] The negative pressure fan is activated to draw air into the inner cavity of unit panel 50, maintaining the negative pressure value precisely within the range of -350Pa to -2000Pa specified in the test standard. The testing personnel can observe whether there is any liquid leakage at each joint of the inner cavity in real time through the transparent high-pressure resistant observation window on the side of the cavity of unit panel 50 with the help of the built-in lighting system, and simultaneously record the leakage location and flow data.

[0028] The sealing scheme between unit panel 50 and flip table 12 is as follows: First, ensure that the protective film on the interior surface profiles of the unit panel is intact; Use a 30mm wide and 0.5mm thick high-adhesion double-sided adhesive tape to attach the standard sealing strip 41 to the three corners of the interior side of unit panel 50; Next, use 30mm wide and 80mm thick sealing strip 41, and apply 30mm thick and 0.5mm thick high-adhesion double-sided adhesive to adhere around the interior side frame of unit panel 50. Figure 5 As shown; Place unit panel 50 flat on the flip table 12, leaving a space (approximately 100mm) between the lower crossbeam of unit panel 50 and the lower edge of the flip table for easy application of tape. Use specimen fastener 40 to clamp and fix the unit plate to the flipping table 12, such as Figure 6 and Figure 7 As shown; Seal the perimeter of unit panel 40 with tape (if possible, only apply two types of sealing strips to the joints).
