Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and more particularly to a on-site detection device for the hardness of curtain wall sealant. Background Art

[0002] A building curtain wall is a building exterior wall composed of panels and a support structure system, which can have a certain displacement ability relative to the main structure or have a certain deformation ability by itself, and does not bear the actions received by the main structure. Waterproofing is a basic performance requirement of the curtain wall. According to the waterproofing method, it is divided into sealant waterproofing and structural waterproofing. Sealant waterproofing is to fill the gaps between the panels or between the panels and the edge materials with sealant to prevent rainwater from leaking into the room.

[0003] Since the sealant is an organic polymer material, after the curtain wall has been used for a certain number of years, the sealant between the panels will age, such as surface fine cracks and unevenness. In severe cases, the sealant will break or be damaged, resulting in leakage of the curtain wall and seriously affecting the use of the building.

[0004] Most of the existing curtain wall detection technologies for the aging and cracking of sealant are still limited to visual inspection methods. Due to the numerous and interconnected gaps in the curtain wall, when leakage is found indoors, it is often difficult to determine the leakage point. Only the sealant in a certain range can be removed, the injection surface of the gap is cleaned, and then the sealant is re-injected, which is inefficient and causes waste of labor and materials. Therefore, we propose a on-site detection device for the hardness of curtain wall sealant to solve the above problems. Summary of the Invention

The pressing component 2 includes a plurality of guide grooves 201. The guide grooves 201 are opened on the outer surface of the assembly cylinder 1. The plurality of guide grooves 201 are evenly distributed around the axis of the assembly cylinder 1. A first fixing groove 202 is opened at the top of the inner cavity of the guide groove 201. A return spring 203 is arranged in the first fixing groove 202. One end of the return spring 203 is fixedly connected to the bottom of the inner cavity of the first fixing groove 202. The other end of the return spring 203 is provided with a guide platform 204. The guide platform 204 is placed in the guide groove 201, and the guide platform 204 is slidably connected to the groove wall of the guide groove 201. A second fixing groove 205 is opened at the top of the end of the guide platform 204 close to the assembly cylinder 1.

A connecting roller 206 is fixedly connected to the bottom of the end of the guide platform 204 away from the assembly cylinder 1. Pressing plates 208 are fixedly connected to the tops of the two guide platforms 204. The two pressing plates 208 are symmetrically distributed along the axis of the assembly cylinder 1.

A receiving ring 211 is fixedly connected to the inner circumferential wall of the rubber ring 209. Place the assembly cylinder 1 at the curtain wall sealant. By pressing the pressing plate 208 to drive the lower pressing ring 207 to move down and contact the rubber ring 209, the lower pressing ring 207 can discharge the air in the hollow chamber 210 at the contact between the rubber ring 209 and the curtain wall, so that the assembly cylinder 1 is connected to the curtain wall. Subsequently, the lower pressing ring 207 returns under the drive of the return spring 203. In subsequent detections, it is also necessary to press the assembly cylinder 1 through the handle 101 for cooperative detection, so that the overall device has stability and ensures the correctness of the detection.

[0031] In order to cooperate with the detection component 3 for detection, a water pipe 401 is provided in the control component 4. One end of the water pipe 401 penetrates through the outer wall of the assembly cylinder 1 and extends to the bottom of the inner cavity of the assembly cylinder 1. The water pipe 401 is fixedly connected to the assembly cylinder 1. One end of the water pipe 401 inside the assembly cylinder 1 is fixedly connected to a water tray 402.

After the fixation is completed, the water in the water tank 406 is discharged into the assembly cylinder 1 through the water pump 405 to cooperate with the pressure sensor 301 in the detection component 3 for detection. After the detection is completed, the water in the assembly cylinder 1 is discharged again, and multiple places can be detected.

[0032] In order to correctly detect whether the sealant leaks, a pressure sensor 301 is provided in the detection component 3. The pressure sensor 301 is placed inside the assembly cylinder 1 and is fixedly connected to the top of the inner cavity of the assembly cylinder 1. The input end of the pressure sensor 301 faces the bottom of the assembly cylinder 1. The output end of the pressure sensor 301 is fixedly connected to a wire 302. The pressure sensor 301 is electrically connected to an external pressure digital display through the wire 302. The input end of the pressure sensor 301 is fixedly connected to a receiving platform 303. The receiving platform 303 is placed inside the assembly cylinder 1 and is slidably connected to the inner wall of the assembly cylinder 1. A plurality of telescopic springs 304 are arranged at the bottom of the receiving platform 303. The plurality of telescopic springs 304 are evenly distributed around the axis of the receiving platform 303. Fixing cylinders 305 are sleeved at both ends of the telescopic spring 304. One fixing cylinder 305 is fixedly connected to the receiving platform 303. The end of the other fixing cylinder 305 away from the receiving platform 303 is fixedly connected to a moving platform 306. The moving platform 306 is placed inside the assembly cylinder 1 and is slidably connected to the inner wall of the assembly cylinder 1. A fixing ring groove 307 is opened around the moving platform 306. A sealing ring 308 is arranged in the fixing ring groove 307. The outer ring wall of the sealing ring 308 contacts and is slidably connected to the inner wall of the assembly cylinder 1. After the fixation is completed, the water is discharged into the assembly cylinder 1 through the control component 4, so that the pressure on the moving platform 306 inside the assembly cylinder 1 is the same as that at the curtain wall sealant. The water is continuously discharged, so that the moving platform 306 moves upward to compress the telescopic spring 304, and then the pressure sensor 301 can be stressed to generate a pressure value. After reaching a certain value, the water discharge is stopped. The change of the pressure sensor is observed through the external display. If there is a leak at the curtain wall sealant, the water will be discharged from the leak, reducing the pressure inside the assembly cylinder 1 and the pressure value. It can be concluded that there is a problem with the curtain wall sealant here, and subsequent maintenance can be carried out.

[0033] Working principle:

[0034] Structural composition:

[0035] Assembly cylinder 1: It includes a detection component 3 at the upper part and a control component 4 at the bottom.

[0036] Pressing component 2: Drives the pressing ring 207 to move through the handle 101 and the manual device, so that it compacts the contact between the curtain wall sealant and the rubber ring 209.

[0037] Water pipe 401 system: Runs through the outer wall of the assembly cylinder 1 to the bottom of the inner cavity, and injects water into the assembly cylinder 1 through the water pump 405 and the water tank 406 to simulate the applied pressure.

[0038] Pressure sensor 301: Installed inside the assembly cylinder 1, monitors the pressure change inside the assembly cylinder 1, and reflects whether the curtain wall sealant leaks.

[0039] Operation process:

[0040] Initial preparation: Install the assembly cylinder 1 at the curtain wall sealant, and ensure that the contact surface is clean and well-sealed.

[0041] Water injection: Inject water into the assembly cylinder 1 by controlling the water pump 405, so that the pressure inside the assembly cylinder 1 gradually increases to simulate the pressure environment in actual use.

[0042] Pressure sensing: The pressure sensor 301 detects the change of the pressure value inside the assembly cylinder 1. If there is a leak, the pressure value will decrease accordingly.

[0043] Data analysis: Observe the output change of the pressure sensor 301 through the external pressure digital display screen to judge whether the curtain wall sealant is intact.

[0044] Detection process:

[0045] Pressure test: After applying a certain pressure, observe the reaction of the pressure sensor 301. Under normal circumstances, the pressure should be stable within a certain numerical range; if there is a leak, the pressure value will change abnormally.

[0046] Result analysis: Judge whether further repair or resealing is required according to the output of the pressure sensor 301.

[0047] By precisely measuring the pressure change through the pressure sensor 301, the sealing state of the curtain wall sealant can be accurately judged, avoiding subsequent problems caused by water leakage. By adopting real-time monitoring technology, the state of the curtain wall sealant can be instantaneously fed back, which is conducive to early detection and solution of potential problems, improving the construction efficiency and quality.

The on-site detection device for the hardness of the curtain wall sealant realizes the effective evaluation and monitoring of the sealing performance of the curtain wall sealant by combining the water pressure simulation and the detection technology of the pressure sensor 301.
