Description

Technical Field

[0002] During the construction process, the quality of roof waterproofing directly affects the service life and safety of the building. Although the existing waterproofing testing methods and technologies can provide certain detection effects, they are still insufficient in comprehensiveness and accuracy. The following is an analysis of two related patents.

[0003] The specification of Chinese invention patent CN116735454B discloses a building waterproof supervision and acceptance system, which includes an inspection frame, a pressure frame and a lifting plate. A group of vertically arranged pressure push rods are installed between the relative surfaces of the inspection frame and the pressure frame. A sealing box with an opening on the bottom surface is fixedly installed on the bottom surface of the pressure frame. A pressure control component fixedly connected to the sealing box is installed on the side of the inspection frame. An electric heating plate is built into the interior of the sealing box. A group of air-driven parts connected to each other through a connecting pipe are installed on the top surface of the pressure frame. The bottom ends of a group of air-driven parts are fixedly connected to the lifting plate. Through the arrangement of mechanisms such as an air supply component, a pressure control component and a liquid injection component, the device can efficiently complete the waterproof acceptance test operation of building materials. During the acceptance experiment, the device has both a fixed-point water injection acceptance mode and a water immersion test mode.

[0004] The specification of Chinese invention patent CN117030571B discloses a waterproof acceptance device for construction engineering supervision, which relates to the field of construction engineering technology. The device includes a frame, on which two moving mechanisms are arranged, and the two moving mechanisms are respectively provided with a first fixed seat and a second fixed seat, and the two moving mechanisms are used to drive the first fixed seat and the second fixed seat to move toward or away from each other; a plurality of fixed columns are arranged in parallel on the first fixed seat, and a plurality of supporting sleeves are arranged in parallel on the second fixed seat, and the number of the fixed columns and the supporting sleeves are equal and the positions correspond; a clamping rubber ring is sleeved on one end of each fixed column close to the supporting sleeve, and a first suction cup is sleeved on the outside of each fixed column, which can reduce water waste during the detection and acceptance process and improve the accuracy of the detection and acceptance.

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0028] It is to be noted that the concepts of directions “left”, “right”, “up”, “down”, “front”, “back”, “inside” and “outside” in the following schemes are all relative directions and will not be listed one by one here.

[0029] Example 1.

[0030] like Figures 1 to 13 As shown, this embodiment provides a roof waterproofing treatment test and acceptance device, which is mainly used to perform infiltration treatment on the waterproof roof to ensure that the roof surface is fully wetted. The specific structure is as follows.

[0031] The controller is responsible for the control and data processing of the entire device. The infiltration box 1, the high-pressure box 2 and the adsorption box 3 are arranged in parallel in sequence for testing at different stages. The sealing mechanism 4 is installed at the bottom of the infiltration box 1, the high-pressure box 2 and the adsorption box 3 to ensure the sealing between each box and the roof during the test.

[0032] The detection mechanism 5 is installed on the infiltration box 1, the high-pressure box 2 and the adsorption box 3, and is used for real-time detection of the state of the roof. The pressure regulating mechanism 6 is installed on the top of the infiltration box 1, the high-pressure box 2 and the adsorption box 3, and is used for adjusting the pressure in each box. The driving mechanism 7 is installed on the sealing mechanism 4, and is used for driving the movement of the sealing mechanism 4. The water tank 8 is fixedly connected to the top of the infiltration box 1, and is used for injecting water into the infiltration box 1.

[0033] The sealing mechanism 4 includes two rollers 9, which are rotatably connected to the bottom ends of the corresponding infiltration box 1, high-pressure box 2 and adsorption box 3 respectively. Rollers 10 are fixedly connected to both ends of the rollers 9. The outer ends of the rollers 10 on the same side are contacted with the same sealing belt 11. The rollers 10 and the sealing belt 11 are both made of rubber. The detection mechanism 5 is composed of a detection strip 12, a detection strip 2 13, a detection strip 3 14 and a detection strip 4 15. These detection strips are all ultrasonic detection strips and are electrically connected to the controller. The pressure regulating mechanism 6 includes a boost pipe 16, a high-pressure pipe 17 and a negative pressure pipe 18 fixedly connected to the top of the infiltration box 1, the high-pressure box 2 and the adsorption box 3, and these pipes are connected to the interior of each box.

[0034] The design of the roller 9 and the roller 10 ensures that the sealing belt 11 is in close contact with the roof to prevent water leakage. The sealing belt 11 is made of rubber material and has good elasticity and sealing performance.

[0035] Detection strip 1 12 is slidably connected to the end of the infiltration box 1 away from the high-pressure box 2, and is used to detect dry roofs. Detection strip 2 13 is located between the infiltration box 1 and the high-pressure box 2, and is used to detect wet roofs. The top of the booster pipe 16 is connected to the inner wall of the water tank 8 to ensure that water can smoothly enter the infiltration box 1.

[0036] Working process Place the device on the top of the waterproof roof to be tested and accepted, and ensure that the position of the device is stable.

[0037] An appropriate amount of water is injected into the infiltration box 1 through the water tank 8 to ensure that the water surface just covers the waterproof roof to be tested and is 1-2 cm higher than the roof. The water volume can be controlled by monitoring the liquid level sensor to ensure that the water level is appropriate.

[0038] Start the driving motor to drive the roller 9 and the sealing belt 11 to rotate through the pulley 22. During the rotation process, the roller 9 and the sealing belt 11 will produce a certain deformation due to their own weight, pressing the roof surface to ensure close contact between the sealing belt 11 and the roof to prevent moisture leakage.

[0039] Driven by the roller 9 and the sealing belt 11, the infiltration box 1, the high-pressure box 2 and the adsorption box 3 move from the adsorption box 3 to the infiltration box 1 to form a closed test space.

[0040] During the movement of the infiltration box 1, water is evenly distributed on the waterproof roof to be tested, ensuring that the roof surface is fully infiltrated. The close contact between the roller 9 and the sealing belt 11 ensures that the inside of the infiltration box 1 is isolated from the outside and water does not leak.

[0041] Test strip 12 Firstly, perform ultrasonic testing on the dry waterproof roof and record the initial status.

[0042] Test strip 2 13 Test the waterproof roof after the infiltration treatment to evaluate the infiltration effect.

[0043] The controller collects the data of the detection strip 1 12 and the detection strip 2 13 in real time, and analyzes the waterproof effect of the waterproof roof by comparing the difference of the detection data.

[0044] The combined design of the drum 9 and the wheel 10 ensures close contact between the sealing belt 11 and the roof, effectively preventing water leakage. The deadweight of the wheel 10 and the elasticity of the rubber material enable the sealing belt 11 to always fit the roof during movement, maintaining good sealing.

[0045] The sealing belt 11 made of rubber material has excellent elasticity and wear resistance, and can maintain a good sealing effect during a long test process.

[0046] Driven by the roller 9 and the sealing belt 11, the water in the wetting box 1 can be evenly coated on the waterproof roof to be tested, ensuring that the roof surface is fully infiltrated. This uniform distribution method helps to find small defects in the roof waterproof layer and improve the accuracy of the test.

[0047] The use of the liquid level sensor ensures the accuracy of the amount of water injected from the water tank 8 into the infiltration tank 1, avoiding too much or too little water affecting the test results. The design of the drive motor and the pulley 22, the drive motor drives the roller 9 and the sealing belt 11 to rotate through the pulley 22, realizes the automatic movement of the device, reduces manual intervention, and improves the test efficiency.

[0048] The controller is responsible for the coordination of the entire device, including the start-up of the drive motor, the monitoring of the liquid level sensor and the collection of detection data, achieving a high degree of automation and simplifying the operation process. The application of ultrasonic detection strips, detection strip 1 12 and detection strip 2 13 are both ultrasonic detection strips, which can detect the status of the roof in real time. Ultrasonic detection technology is non-destructive and highly sensitive, and can accurately capture subtle changes in the roof waterproofing layer.

[0049] The controller collects data from the detection strip 1 12 and the detection strip 2 13 in real time, and quickly evaluates the waterproof effect of the waterproof roof through comparative analysis. This real-time detection function helps to find potential problems in time and improve the reliability and accuracy of the test.

[0050] This device can not only perform infiltration treatment, but also integrates the functions of high-pressure treatment and negative pressure treatment. It can complete multiple stages of testing in one test process, which improves the comprehensiveness and efficiency of the test. It has strong adaptability. The design of the device is suitable for waterproof roofs of different types and structures. It has strong adaptability and flexibility, and can meet the testing needs of different scenarios. Water recycling, through reasonable water channel design, the water in the device can be recycled many times, reducing the waste of water resources, meeting environmental protection requirements, low energy consumption operation, and the efficient design of the drive motor and controller makes the device low in energy consumption during operation, reducing the testing cost.

[0051] Through the above examples, this device can efficiently and accurately perform infiltration treatment and preliminary inspection on waterproof roofs, laying a solid foundation for subsequent high pressure and negative pressure tests. I hope these suggestions are helpful to you! If you have any other questions or need further optimization, please feel free to let me know.

[0052] Example 2 like Figures 1 to 13 As shown, this embodiment provides a roof waterproofing treatment test and acceptance device based on embodiment 1. The device is mainly used to perform high-pressure treatment on the waterproof roof to test its sealing and pressure resistance. The specific structure is as follows.

[0053] The controller is responsible for the control and data processing of the entire device. The infiltration box 1, the high-pressure box 2 and the adsorption box 3 are arranged in parallel in sequence for testing at different stages. The sealing mechanism 4 is installed at the bottom of the infiltration box 1, the high-pressure box 2 and the adsorption box 3 to ensure the sealing between each box and the roof during the test.

[0054] The detection mechanism 5 is installed on the infiltration box 1, the high-pressure box 2 and the adsorption box 3, and is used for real-time detection of the state of the roof. The pressure regulating mechanism 6 is installed on the top of the infiltration box 1, the high-pressure box 2 and the adsorption box 3, and is used for adjusting the pressure in each box. The driving mechanism 7 is installed on the sealing mechanism 4, and is used for driving the movement of the sealing mechanism 4. The water tank 8 is fixedly connected to the top of the infiltration box 1, and is used for injecting water into the infiltration box 1.

[0055] The sealing mechanism 4 includes two rollers 9, which are rotatably connected to the bottom ends of the corresponding infiltration box 1, high-pressure box 2 and adsorption box 3 respectively. Rollers 10 are fixedly connected to both ends of the rollers 9. The outer ends of the rollers 10 on the same side are contacted with the same sealing belt 11. The rollers 10 and the sealing belt 11 are both made of rubber.

[0056] The detection mechanism 5 is composed of detection strip 1 12, detection strip 2 13, detection strip 3 14 and detection strip 4 15, all of which are ultrasonic detection strips and are electrically connected to the controller. The pressure regulating mechanism 6 includes a boost pipe 16, a high pressure pipe 17 and a negative pressure pipe 18 fixedly connected to the top of the infiltration box 1, the high pressure box 2 and the adsorption box 3, and these pipes are connected to the interior of each box.

[0057] Detection strip one 12 is slidably connected to the end of the infiltration box 1 away from the high-pressure box 2, and is used to detect dry roofs. Detection strip two 13 is located between the infiltration box 1 and the high-pressure box 2, and is used to detect wet roofs. Detection strip three 14 is located between the high-pressure box 2 and the adsorption box 3, and is used to detect roofs treated with high pressure. Detection strip four 15 is slidably connected to the end of the adsorption box 3 away from the high-pressure box 2, and is used to detect roofs treated with negative pressure.

[0058] The boost pipe 16 and the high-pressure pipe 17 are connected by a pipeline, and a one-way pressure reducing valve is provided in the pipeline to ensure that the pressure in the high-pressure box 2 is greater than the pressure in the infiltration box 1. A multi-stage centrifugal pump 19 is fixedly connected between the high-pressure pipe 17 and the negative pressure pipe 18 to adjust the pressure in each box.

[0059] The bottom end of the drum 9 and the bottom end of the sealing belt 11 are located on the same plane, and the outer wall of the sealing belt 11 is arranged in contact with the end of the drum 9 to ensure the sealing effect. A solenoid valve is fixedly connected between the boost pipe 16 and the water tank 8, and the solenoid valve is electrically connected to the controller to control the flow of water. A liquid level sensor is fixedly connected inside the infiltration box 1 to monitor the water level.

[0060] Working process Place the device on the top of the waterproof roof to be tested and accepted, and ensure that the position of the device is stable.

[0061] An appropriate amount of water is injected into the infiltration box 1 through the water tank 8 to ensure that the water surface just covers the waterproof roof to be tested and is 1-2 cm higher than the roof. The water volume can be controlled by monitoring the liquid level sensor to ensure that the water level is appropriate.

[0062] Start the driving motor, and drive the roller 9 and the sealing belt 11 to rotate through the pulley 22. During the rotation process, the roller 9 and the sealing belt 11 produce a certain deformation due to their own weight, pressing the roof surface to ensure the close contact between the sealing belt 11 and the roof to prevent moisture leakage. Driven by the roller 9 and the sealing belt 11, the infiltration box 1, the high-pressure box 2 and the adsorption box 3 move from the adsorption box 3 to the infiltration box 1 to form a closed test space. Start the multi-stage centrifugal pump 19, and inject high-pressure gas into the high-pressure box 2 through the booster pipe 16 and the high-pressure pipe 17, so that the pressure in the high-pressure box 2 is greater than the pressure in the infiltration box 1. The high-pressure gas enters the high-pressure box 2 through the one-way pressure reducing valve to ensure the stability of the pressure.

[0063] The high-pressure gas in the high-pressure box 2 causes the water on the surface of the waterproof roof to be tested to generate pressure to penetrate into the roof. If there are gaps in the roof, water will penetrate into the interior, achieving a high-pressure penetration test.

[0064] Test Article 3 14 Test the waterproof roof after high pressure treatment to evaluate the high pressure penetration effect.

[0065] The controller collects the data of the detection strip 3 14 in real time, and analyzes the high-pressure penetration performance of the waterproof roof by comparing the differences in the detection data.

[0066] The multi-stage centrifugal pump 19 can provide stable high-pressure gas to ensure that the pressure in the high-pressure box 2 is higher than the pressure in the infiltration box 1. This high-pressure environment is helpful to test the performance of the waterproof roof under high-pressure conditions that may be encountered in actual use. The design of the one-way pressure reducing valve ensures that the high-pressure gas can only enter the high-pressure box 2 from the booster pipe 16, preventing reverse flow and ensuring the stability of the pressure.

[0067] The design of the drum 9 and the roller 10 ensures the close contact between the sealing belt 11 and the roof, effectively preventing water leakage. The dead weight of the roller 10 and the elasticity of the rubber material enable the sealing belt 11 to always fit the roof during movement and maintain good sealing.

[0068] The sealing belt 11 made of rubber material has excellent elasticity and wear resistance, and can maintain a good sealing effect during a long test process.

[0069] The driving motor drives the roller 9 and the sealing belt 11 to rotate through the pulley 22, thereby realizing the automatic movement of the device, reducing manual intervention and improving the test efficiency.

[0070] The controller is responsible for the coordination of the entire device, including the start-up of the drive motor, the monitoring of the liquid level sensor, the control of the multi-stage centrifugal pump 19 and the collection of detection data, achieving a high degree of automation and simplifying the operation process.

[0071] The detection strips 3 and 14 are all ultrasonic detection strips, which can detect the roof status after high-pressure treatment in real time. The ultrasonic detection technology has the characteristics of non-destructiveness and high sensitivity, and can accurately capture the subtle changes of the roof waterproof layer.

[0072] The controller collects the data of the detection strip 314 in real time, and through comparative analysis, quickly evaluates the high-pressure penetration performance of the waterproof roof. This real-time detection function helps to discover potential problems in time and improve the reliability and accuracy of the test.

[0073] This device is not only capable of high-pressure treatment, but also integrates the functions of infiltration treatment and negative pressure treatment. It can complete multiple stages of testing in one test process, which improves the comprehensiveness and efficiency of the test. It has strong adaptability.

The detection strip 2 13 is located between the infiltration box 1 and the high-pressure box 2, and is used to detect wet roofs. The detection strip 3 14 is located between the high-pressure box 2 and the adsorption box 3, and is used to detect roofs after high-pressure treatment. The detection strip 4 15 is slidably connected to the end of the adsorption box 3 away from the high-pressure box 2, and is used to detect roofs after negative pressure treatment.

[0084] The top of the boost pipe 16 is connected to the inner wall of the water tank 8 to ensure that water can smoothly enter the infiltration tank 1.

[0085] The infiltration box 1, the high-pressure box 2 and the adsorption box 3 all include a U-shaped cover 20, and the two ends of the U-shaped cover 20 are fixedly connected with end covers 21. The end covers 21 and the corresponding positions of the rollers 10 and the sealing belts 11 are provided with grooves for accommodating the rollers 10 and the sealing belts 11. A secondary roller is provided on the upper side of the roller 10, and the secondary roller is rotatably connected to the end cover 21. A pulley 22 is fixedly connected to the corresponding position of the roller 10 on the end cover 21, and the rotating shaft of the pulley 22 passes through the end cover 21 and is fixedly connected to the corresponding roller 10.

[0086] Two adjacent pulleys 22 are connected by a synchronous belt. The tops of the infiltration box 1, the high-pressure box 2 and the adsorption box 3 are fixedly connected to the same bracket, and the end of the bracket close to the adsorption box 3 is fixedly connected to a driving motor.

[0087] The drive motor is electrically connected to the controller, and the pulley 22 near the drive motor is connected to the drive motor through a synchronous belt. The outer end of each roller 9 is rotatably connected to a card plate, and the card plate is fixedly connected to the bottom end of the corresponding U-shaped cover 20 through a dovetail tenon. A handle is provided at one end of the bracket near the adsorption box 3.

[0088] Working process Place the device on the top of the waterproof roof to be tested and accepted, and ensure that the position of the device is stable.

[0089] An appropriate amount of water is injected into the infiltration box 1 through the water tank 8 to ensure that the water surface just covers the waterproof roof to be tested and is 1-2 cm higher than the roof. The water volume can be controlled by monitoring the liquid level sensor to ensure that the water level is appropriate.

[0090] Start the driving motor, and drive the roller 9 and the sealing belt 11 to rotate through the pulley 22. During the rotation process, the roller 9 and the sealing belt 11 produce a certain deformation due to their own weight, pressing the roof surface to ensure the close contact between the sealing belt 11 and the roof to prevent moisture leakage. Driven by the roller 9 and the sealing belt 11, the infiltration box 1, the high-pressure box 2 and the adsorption box 3 move from the adsorption box 3 to the infiltration box 1 to form a closed test space. Start the multi-stage centrifugal pump 19, and suck out the gas in the adsorption box 3 through the negative pressure pipe 18, so that a negative pressure environment is formed in the adsorption box 3. The negative pressure gas flows into the high-pressure box 2 and the infiltration box 1 respectively through the pipeline, and the pressure in the high-pressure box 2 is made greater than the pressure in the infiltration box 1 through the pressure reducing valve.

[0091] The negative pressure in the adsorption box 3 attracts the waterproof roof to be tested, and further tests its sealing and adsorption performance. The detection strip 24 15 detects the waterproof roof after negative pressure treatment to evaluate the effect of negative pressure treatment.

[0092] The controller collects the data of the detection strip 415 in real time, and analyzes the negative pressure adsorption performance of the waterproof roof by comparing the differences in the detection data.

[0093] The multi-stage centrifugal pump 19 can provide a stable negative pressure environment to ensure that the pressure in the adsorption box 3 is lower than the external atmospheric pressure. This negative pressure environment is helpful to test the performance of the waterproof roof under negative pressure conditions that may be encountered in actual use.

[0094] Negative pressure gas flows into the high-pressure box 2 and the infiltration box 1 through pipelines respectively, and the pressure in the high-pressure box 2 is made greater than the pressure in the infiltration box 1 through the pressure reducing valve, ensuring reasonable pressure distribution in each box. The design of the drum 9 and the roller 10 and the combined design of the drum 9 and the roller 10 ensure close contact between the sealing belt 11 and the roof, effectively preventing water leakage. The dead weight of the roller 10 and the elasticity of the rubber material enable the sealing belt 11 to always fit the roof during the movement and maintain good sealing.

[0095] The sealing belt 11 made of rubber material has excellent elasticity and wear resistance, and can maintain a good sealing effect during a long period of testing. The design of the auxiliary roller, in which an auxiliary roller is provided on the upper side of the roller 10 and the auxiliary roller is rotatably connected to the end cover 21, further enhances the sealing effect and ensures uniform pressure distribution in each box.

[0096] The driving motor drives the roller 9 and the sealing belt 11 to rotate through the pulley 22, thereby realizing the automatic movement of the device, reducing manual intervention and improving the test efficiency.

[0097] The integrated control of the controller is responsible for the coordination of the entire device, including the start-up of the drive motor, the monitoring of the liquid level sensor, the control of the multi-stage centrifugal pump 19 and the collection of detection data, which achieves a high degree of automation and simplifies the operation process.

[0098] The detection strips 4 and 15 are all ultrasonic detection strips, which can detect the status of the roof after negative pressure treatment in real time. Ultrasonic detection technology is non-destructive and highly sensitive, and can accurately capture subtle changes in the roof waterproof layer. The data is collected and analyzed in real time. The controller collects the data of the detection strip 4 and 15 in real time, and through comparative analysis, quickly evaluates the negative pressure adsorption performance of the waterproof roof. This real-time detection function helps to discover potential problems in time and improve the reliability and accuracy of the test.

[0099] This device is not only capable of negative pressure treatment, but also integrates the functions of infiltration treatment and high pressure treatment. It can complete multiple stages of testing in one test process, which improves the comprehensiveness and efficiency of the test. It has strong adaptability. The design of the device is suitable for waterproof roofs of different types and structures. It has strong adaptability and flexibility and can meet the testing needs of different scenarios.

[0100] Through reasonable water channel design, the water in the device can be recycled for multiple times, reducing the waste of water resources, meeting environmental protection requirements, and operating with low energy consumption. The efficient design of the multi-stage centrifugal pump 19 and the controller makes the device consume less energy during operation and reduces the testing cost.
