[0002] Architecture refers to all kinds of man-made structures and buildings. It is a spatial environment with specific functions formed on or under the ground by human beings using certain materials and technical means to meet their needs for living, production and social activities. As demand increases, new buildings are often built next to old buildings, and concrete is used to connect the two buildings, thereby expanding the building space.
[0003] In the construction field, the sealing performance of structural joints is directly related to the quality, safety and service life of buildings. Among many engineering structures, joints are high-risk areas for leakage problems. Existing technologies cannot monitor and warn of leakage at joints, which often leads to the leakage being discovered only when it is already quite serious. Therefore, a structural joint leakage early warning device is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a structural joint leakage early warning device to solve the problem mentioned in the background art that existing devices cannot monitor and warn of leakage at joints.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A structural joint leakage early warning device includes a sensor body. A water collection frame is fixedly connected to the top of the sensor body. A horizontal through-slot is formed on both the left and right top sides of the water collection frame. Symmetrically arranged side plates are fixedly connected to the top of the front and rear top sides of the water collection frame. A fixing hole is provided below the through-slot, passing horizontally through the water collection frame. A horizontally arranged semi-open pipe is provided inside each of the two through-slots. A mounting plate is fixedly connected to the top of the front and rear top sides of the semi-open pipe. A retainer is provided on the outside of the mounting plate. A water baffle is fixedly connected to the inner side of the semi-open pipe away from the water collection frame. A fixing ring is fixedly connected to the outer side of the semi-open pipe near the water collection frame. A mounting hole plate is fixedly connected to the bottom of the fixing ring. A mounting bolt is inserted into the inner side of the mounting hole plate, and a mounting nut is threaded onto the outer side of the mounting bolt.

[0017] Please see Figure 1-4 This utility model provides a technical solution: A structural joint leakage early warning device includes a sensor body 1. A water collection frame 2 is fixedly connected to the top of the sensor body 1. Horizontal through-slots 3 are formed on both the left and right top sides of the water collection frame 2. Symmetrically arranged side plates 4 are fixedly connected to the top of the front and rear top sides of the water collection frame 2. A fixing hole 5 is provided below the through-slots 3, horizontally arranged semi-open pipes 6 are provided inside each of the two through-slots 3. Mounting plates 7 are fixedly connected to the top of the front and rear top sides of the semi-open pipes 6. A retainer 8 is provided on the outside of the mounting plates 7. A baffle plate 9 is fixedly connected to the inner side of the semi-open pipe 6 away from the water collection frame 2. A fixing ring 10 is fixedly connected to the outer side of the semi-open pipe 6 near the water collection frame 2. A mounting hole plate 11 is fixedly connected to the bottom of the fixing ring 10. A mounting bolt 12 is inserted into the inner side of the mounting hole plate 11, and a mounting nut 13 is threaded onto the outer side of the mounting bolt 12. The inner side of the through groove 3 is tightly fitted to the outer side of the semi-open pipe 6. The fixing ring 10 is located inside the water collection frame 2 and is tightly fitted to the water collection frame 2. The mounting plate 11 is horizontally aligned with the fixing hole 5. The mounting bolt 12 is inserted into the inner side of the fixing hole 5. The side plate 4 is provided with a drain hole 14 that is opened on the front and rear sides of the water collection frame 2 and passes through the water collection frame 2. The drain hole 14 is located at the top of the front and rear sides of the water collection frame 2. Through the sensor body 1, water collection frame 2, through groove 3, side plate 4, fixing hole 5, semi-open pipe 6, mounting plate 7, baffle plate 9 and fixing ring 10, if leakage occurs at the joint of the structure, water can drip into the inner side of the semi-open pipe 6. Since one end of the semi-open pipe 6 is sealed by the baffle plate 9, water can only enter the water collection frame 2 through the other end of the semi-open pipe 6. At this time, the sensor body 1 can detect water and issue an early warning, thereby avoiding greater losses caused by long-term leakage at the joint.
[0018] The fixture 8 includes a fixing bolt 81 located at the bottom of the mounting plate 7. The fixing bolt 81 is threadedly connected to a fixing plate 82, and an expansion bolt 83 is rotatably connected to the inside of the fixing plate 82. Multiple fixtures are provided. The top of the fixing bolt 81 fits tightly against the bottom of the mounting plate 7. Through the fixture 8, fixing bolt 81, fixing plate 82, expansion bolt 83, mounting hole plate 11, mounting bolt 12, and mounting nut 13, when repairing at the joint, the fixing bolt 81 can be loosened and the fixing plate 82 can be rotated to remove the semi-open pipe 6, thereby treating the leakage at the joint. This design simplifies the installation and disassembly steps of the semi-open pipe 6, making it convenient for workers to maintain the joint.
[0019] Workflow: When installation is required, first place the semi-open pipe 6 at the joint and mark the ceiling to determine the installation point of the fixing device 8. Then, use a power source to drill holes at the installation points, insert the expansion tube into the air, and screw the expansion bolt 83 into the expansion tube. Next, place the semi-open pipe 6 between multiple fixing devices 8, rotate the fixing plate 82 outside the expansion bolt 83 to move the fixing bolt 81 to the bottom of the mounting plate 7, and then rotate the fixing bolt 81 until the bottom of the fixing bolt 81 is tightly fitted with the top of the mounting plate 7. This completes the installation of the semi-open pipe 6. Then, use the same method to install another semi-open pipe 6, leaving a certain gap between the two semi-open pipes 6, making the gap the same as the inner diameter of the water collection frame 2. Then, put the water collection frame 2 on the outside of the fixing ring 10 of the two semi-open pipes 6, so that the semi-open pipe 6 is located inside the through groove 3, and the side plate 4 is located at the bottom of the mounting plate 7. At this time, the fixing hole 5 and the mounting hole plate 11 at the bottom of the fixing ring 10 are horizontally aligned. To install the device, insert the mounting bolt 12 into the fixing hole 5 and the fixing ring 10, and screw the mounting nut 13 onto the outside of the mounting bolt 12. Finally, connect the sensor body 1 to the computer or other monitoring equipment, and the device can be used normally. If leakage occurs at the structural joint, water can drip into the inside of the semi-open pipe 6. Since one end of the semi-open pipe 6 is sealed by the water baffle 9, water can only enter the water collection frame 2 through the other end of the semi-open pipe 6. At this time, the sensor body 1 can detect water and issue an early warning, thereby avoiding greater losses due to long-term leakage at the joint. The drain hole 14 can drain water when the water collection frame 2 is almost full, preventing the device from falling off due to excessive water pressure inside the device. When repairing at the joint, the fixing bolt 81 can be loosened and the fixing plate 82 can be rotated to remove the semi-open pipe 6, and then the leakage at the joint can be treated. The design of the fixing device 8 and its connecting components makes the installation and disassembly steps of the semi-open pipe 6 simple, which is convenient for staff to maintain the joint.
