Description

Technical Field

[0001] This invention belongs to the field of concrete performance testing technology, specifically a BIM-based building concrete performance testing device and method. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which uses cement as the cementing material, sand and gravel as aggregates, and water in a specific ratio, and is obtained through mixing.

[0003] The impermeability of concrete refers to its ability to resist water penetration. Current methods for testing the impermeability of concrete involve placing concrete blocks into an impermeability mold, then spirally installing the concrete blocks into an existing impermeability tester using the mold. This process usually requires tightening with a wrench, which is time-consuming and labor-intensive. Subsequently, the experimental data is recorded in text form using a supporting control system and related sensors, and data analysis is also required. Furthermore, this method cannot test the compressive strength of concrete, or its compressive strength in water or sewage environments. It is also not convenient for testing the performance of concrete with multiple shapes and materials. Summary of the Invention

Detailed Implementation

[0022] like Figures 1-15As shown, this invention provides a BIM-based building concrete performance testing device, including a testing box 1. The testing box 1 contains a testing mechanism for testing the performance of concrete columns. The testing mechanism includes a seepage prevention performance testing component and a compressive strength performance testing component. The seepage prevention performance testing component is used to test the seepage prevention performance of the concrete column, and the compressive strength performance testing component is used to test the compressive strength performance of the concrete column. The compressive strength performance testing component includes a testing chamber 10 within the testing box 1. Pressure rods 12 are fixedly connected in an array on the upper end wall of the testing chamber 10. The pressure rods 12 are used to push the pressure block 13 to move. The pressure rods 12 are signal-connected to the operation display panel 6. A pressure block 13 is fixedly connected to the lower end of the pressure rods 12. The pressure block 13 is used to compress the concrete column for compressive strength testing. The end wall of the testing chamber 10 has... The device is equipped with a lifting chute 31, on which a lifting screw 33 is rotatably connected. The lifting screw 33 is threadedly connected to a lifting nut block 32, which is slidably connected between the end walls of the lifting chute 31. A support plate 41 is fixedly installed between the lifting nut blocks 32. The support plate 41 is used to install the water collection cylinder 37. The water collection cylinder 37 is slidably connected through the support plate 41. The water collection cylinder 37 is used to collect water and support the feeding plate 56, increasing the stability of the feeding plate 56. The outer surface of the water collection cylinder 37 is provided with an array of support chute 38. A support slider 39 is fixedly connected to the support plate 41 and slidably connected between the end walls of the support chute 38. A pushing mechanism is provided on the bottom wall of the water collection cylinder 37. The pushing mechanism is used to push the water collection cylinder 37 to move and drive the lifting screw 33 to rotate. The seepage prevention performance testing component includes an array of seepage prevention testing electric push rods 11 fixedly connected to the end wall of the testing chamber 10. The seepage prevention testing electric push rods 11 drive the circular frame 16 to move, thereby facilitating the movement of the nozzles 15. A pressure rod 12 is located inside the seepage prevention testing electric push rods 11. A circular frame 16 is fixedly connected to the lower end of the seepage prevention testing electric push rods 11. The circular frame 16 prevents water splashing, allowing water to fall onto the surface of the concrete column. A circular array of nozzles 15 is fixedly installed on the bottom wall of the seepage prevention testing electric push rods 11. The nozzles 15 spray water onto the surface of the concrete column. The nozzles 15 communicate with an annular groove 60, which is located within the seepage prevention... Inside the detection electric push rod 11, the seepage detection electric push rod 11 is connected to the water tank 2 via a water supply pipe 14. The water supply pipe 14 is used to input water from the water tank 2 into the annular groove 60, so that the nozzle 15 can spray it out. The nozzle 15 is signal-connected to the operation display panel 6. The seepage detection electric push rod 11 is signal-connected to the operation display panel 6. The water tank 2 is fixedly installed on the upper surface of the detection box 1. The water tank 2 stores water. A liquid level sensor 40 is fixedly connected inside the water collection cylinder 37. The liquid level sensor 40 is used to detect the water level in the water collection cylinder 37. The liquid level sensor 40 is signal-connected to the operation display panel 6. This energizes the electric push rod 11 for seepage detection, causing the annular frame 16 to move downwards. This causes the nozzle 15 to move downwards and approach the concrete column, activating the nozzle 15. Water from the water tank 2 then enters the annular groove 60 through the water supply pipe 14 and is sprayed onto the surface of the concrete column by the nozzle 15. After a period of time, water enters the water collection cylinder 37 through the leakage hole 27. The level sensor 40 detects the water level in the water collection cylinder 37. When the level sensor 40 detects water, it indicates that the corresponding concrete column has poor seepage prevention performance. Based on the water level detected by the level sensor 40, the seepage prevention performance of the concrete column is judged. The water level reading detected by the level sensor 40 is displayed on the operation display panel 6. This energizes the pressure rod 12, causing the pressure block 13 to move downwards and contact the concrete column, thus compressing the concrete column. The lifting screw 33 rotates, thereby driving the lifting nut block 32 to move, which in turn drives the support plate 41 to move upward, thus supporting the feeding plate 56. The water collection cylinder 37 moves upward, thus supporting the feeding plate 56. When the support plate 41 moves to contact the feeding plate 56, the water collection cylinder 37 just moves to contact the feeding plate 56, supporting the feeding plate 56. The support plate 41 drives the support slider 39 to move upward, moving to contact the upper end wall of the support groove 38, further supporting the water collection cylinder 37 and the feeding plate 56. The pressure block 13 presses the concrete column. When the concrete column is damaged, the pressure value applied by the pressure rod 12 displayed on the operation display panel 6 is recorded, thereby realizing the detection of the compressive strength of the concrete. It can realize the detection of the compressive strength of concrete columns in water-containing and waterless environments.

This starts the drive motor 8, which drives the drive shaft 44 to rotate, thereby driving the drive pulley 50 to rotate. The drive pulley 50 and the driven pulley 52 are connected by the transmission belt 51, which drives the worm shaft 43 to rotate, thereby driving the worm 53 to rotate. The worm 53 meshes with the worm wheel 54, thereby driving the worm wheel shaft 47 to rotate, thereby driving the third bevel gear 48 to rotate. The third bevel gear 48 meshes with the fourth bevel gear 49, thereby driving the push screw 36 to rotate. The push screw 36 is threadedly connected to the push nut sleeve 35, thereby driving the push nut sleeve 35 to move upward, thereby driving the water collection cylinder 37 to move upward. The drive shaft 44 rotates, thereby driving the first bevel gear 46 to rotate. The first bevel gear 46 meshes with the second bevel gear 45, thereby driving the lifting screw 33 to rotate.

[0024] Advantageously, a feeding mechanism is provided on the end wall of the testing box 1. This feeding mechanism is used to supply material to the concrete column for easy testing.

The feed plate 56 is evenly provided with transport grooves 25. The transport grooves 25 are used to place concrete columns for easy inspection. Clamping electric push rods 26 are fixedly installed in a circumferential array on the end wall of the transport groove 25. The clamping electric push rods 26 clamp the concrete column. The clamping electric push rods 26 are connected by a wire. Drainage holes 27 are evenly provided on the bottom wall of the transport groove 25 to allow water to pass through. The concrete column then enters the transport trough 25. The clamping electric push rod 26 is energized to clamp the concrete column, and the feeding motor is started, which drives the feeding screw 30 to rotate, thereby driving the feeding nut block 55 to move, which in turn drives the feeding plate 56 to move, which in turn drives the clamping electric push rod 26 to move, thus moving the concrete column into the detection chamber 10 for inspection.

[0025] Advantageously, the feeding box 3 is equipped with a casting and molding mechanism, which is used to cast and mold concrete columns into different shapes for easy inspection.

The model cylinder 21 can be provided with different shapes to facilitate the casting and molding of concrete of different shapes. The model cylinder 21 is threadedly connected to the threaded hole 65. The model cylinder 21 is inserted into the through hole. This allows the concrete supply pipe to be connected to the conveying pipe 4. Different materials of concrete can be connected to the conveying pipe 4, facilitating the testing of concrete columns made of different materials.

[0032] The working process of this invention involves powering the entire device, inputting corresponding commands on the operation display panel 6, retrieving the BIM-modeled model of the model cylinder 21, and sending signals to the corresponding components to cause them to move. This connects the concrete supply pipe to the conveying pipe 4, which can be connected to concrete of different materials for easy inspection of concrete columns made of different materials. The concrete enters the pouring electric push rod 19 through the conveying pipe 4. Powering the pouring electric push rod 19 causes it to move downwards and contact the model cylinder 21, allowing the concrete material to enter the model cylinder 21 through the pouring electric push rod 19 for pouring and shaping. After completion, the scraping motor is started, which drives the scraping screw 20 to rotate, thereby moving the scraping nut block 23, which in turn moves the scraper 22 to scrape off excess material. The excess material then enters the receiving box 5 through the collection channel 24 for collection. After cooling for a period of time and completion of pouring, the sealing motor is started, which drives the gear shaft 64 to rotate, thereby rotating the gear 63. The gear 63 meshes with the sealing plate 66, causing the sealing plate 66 to move, thus opening the bottom of the model cylinder 21. After the bottom of the model cylinder 21 opens, the pouring electric push rod 19 moves downward, pushing the concrete column downward into the transport trough 25. The inner surface of the molded cylinder 21 is smooth to prevent adhesion and make it difficult to push. The concrete column enters the transport trough 25. The clamping electric push rod 26 is energized to clamp the concrete column. The feeding motor is started, which drives the feeding screw 30 to rotate, thereby driving the feeding nut block 55 to move, which in turn drives the feeding plate 56 to move, which in turn drives the clamping electric push rod 26 to move, thus moving the concrete column into the detection chamber 10 for detection. The seepage prevention detection electric push rod 11 is energized, which drives the ring frame 16 to move downward, causing the nozzle 15 to move downward and approach the concrete column. The nozzle 15 is turned on, allowing water from the water tank 2 to enter through the water supply pipe 14. Water is sprayed onto the surface of the concrete column through the nozzle 15 into the annular groove 60. After a period of time, water enters the water collection cylinder 37 through the leakage hole 27. The liquid level sensor 40 detects the water level in the water collection cylinder 37. When the liquid level sensor 40 detects water, it indicates that the corresponding concrete column has poor seepage prevention performance. The seepage prevention performance of the concrete column is judged based on the water level detected by the liquid level sensor 40. The water level reading detected by the liquid level sensor 40 is displayed on the operation display panel 6. The pressure rod 12 is energized, thereby driving the pressure block 13 to move downward and contact the concrete column, pressing the concrete column. The push motor 8 is started, thereby driving the drive shaft 44 to rotate.This causes the drive pulley 50 to rotate. The drive pulley 50 and the driven pulley 52 are connected by the transmission belt 51, which in turn drives the worm shaft 43 to rotate, thereby driving the worm 53 to rotate. The worm 53 meshes with the worm wheel 54, thereby driving the worm wheel shaft 47 to rotate, which in turn drives the third bevel gear 48 to rotate. The third bevel gear 48 meshes with the fourth bevel gear 49, thereby driving the push screw 36 to rotate. The push screw 36 is threadedly connected to the push nut sleeve 35, thereby driving the push nut sleeve 35 to move upward, which in turn drives the water collection cylinder 37 to move upward. The drive shaft 44 rotates, thereby driving the first bevel gear 46 to rotate. The first bevel gear 46 meshes with the second bevel gear 45, thereby driving the lifting screw 33 to rotate, which in turn drives... The movement of the lifting nut block 32 causes the support plate 41 to move upward, thereby supporting the feeding plate 56. The water collection cylinder 37 moves upward, thus supporting the feeding plate 56. When the support plate 41 moves to contact the feeding plate 56, the water collection cylinder 37 also moves to contact the feeding plate 56, supporting it. The support plate 41 drives the support slider 39 to move upward, until it contacts the upper end wall of the support groove 38, further supporting the water collection cylinder 37 and the feeding plate 56. The pressure block 13 presses the concrete column. When the concrete column is damaged, the pressure value applied by the pressure rod 12 displayed on the operation display panel 6 is recorded, thereby realizing the detection of the compressive strength of the concrete. This allows for the detection of the compressive strength of concrete columns in both water-rich and waterless environments.
