Description

Technical Field

[0001] This invention relates to the field of grouting measurement technology, and specifically to a device for detecting the fullness of grouting in prefabricated building sleeves. Background Technology

[0002] In prefabricated buildings, sleeve grouting technology is widely used, primarily for connecting precast concrete components to ensure the stability and safety of the building structure. In this process, the sleeve is a hollow circular tube into which cement mortar or a special grouting material is poured, ensuring complete filling and forming a robust connection. However, the completeness of the grout filling in the sleeve directly affects the building's safety. Incomplete grouting can create weak points at the connection, impacting the overall structural integrity. Therefore, checking the completeness of the grout filling in the sleeve is a crucial step.

[0003] Currently, there are some existing technologies that can measure the grout fullness of prefabricated sleeves. For example, patent publication number CN119754556A mainly uses the following technical means: air is gradually discharged from the grout outlet, the air pressure of the collected air is detected, and the grout fullness is automatically calculated and quantitatively analyzed by converting the air pressure. When the detected grout fullness reaches the preset standard value, grouting is automatically stopped and pressure is maintained. After analysis, the drawbacks of this technical solution are: the inner wall of the sleeve and the inside of the pipe cannot be cleaned before grouting; the electronic components set in the collection chamber for collecting the discharged gas are easily damaged by impurities blown by the gas; and the presence of impurities in the inner wall of the sleeve and the pipe will cause uneven filling of the grout in the sleeve, resulting in extremely low grout fullness in the sleeve. Based on this, the present invention provides a prefabricated building sleeve grout fullness detection device with a simple and ingenious structure that can automatically detect and remove impurities in the inner wall of the sleeve and the pipe before grouting.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-3 As shown, the present invention is a device for detecting the grout fullness of prefabricated building sleeves, comprising: The base 1 is provided with a sleeve positioning component 2 for fixing the sleeve and the reinforcing bar. The base 1 is also fixed with an inlet pipe 3 connected to the grouting hole of the sleeve and an outlet pipe 8 connected to the grout outlet hole of the sleeve. The inlet pipe 3 is connected to the grout pipe 4 and the air supply pipe 5 through a three-way valve 6. The end of the sleeve is detachably connected with a first sealing component and a second sealing component. Grouting assembly 10 is fixed on base 1 and connected to grout pipe 4; The first air box 11 is fixed on the base 1 and connected to the injection pipe 8. The injection pipe 8 is equipped with a first solenoid valve 9. The first air box 11 is equipped with a pressure sensor 15, and the pressure sensor 15 is connected to the grouting assembly 10. The second air box 12 is fixed to the base 1 and connected to the air supply pipe 5. The first air box 11 and the second air box 12 are connected by a connecting pipe 13, and a second solenoid valve 14 is provided on the connecting pipe 13. An air pump 17 is provided inside the second air box 12 and is connected to the connecting pipe 13. The cleaning component 20 is slidably connected to the positioning plate 22 mounted on the base 1. The cleaning component 20 is slidably engaged with the sleeve, and its edge is in contact with the inner wall of the sleeve. The positioning plate 22 is equipped with a transmission assembly 21 for driving the cleaning component 20 to rise and fall, and the transmission assembly 21 is connected to the air supply pipe 5. The positioning plate 22 is equipped with a distance sensor 16 for monitoring the upward displacement of the cleaning component 20, and the distance sensor 16 is connected to the three-way valve 6, the first solenoid valve 9, and the second solenoid valve 14.

[0021] In one embodiment, the sleeve positioning component 2 includes a first ring and a second ring. The first ring is fixed to the base 1, and the first and second rings are connected by a snap-fit. The inner walls of both the first and second rings are provided with an anti-slip layer and fit snugly against the outer wall of the sleeve. The three-way valve 6 includes one outlet and two inlets. Its outlet is connected to the injection pipe 3, and its two inlets are respectively connected to the slurry pipe 4 and the air supply pipe 5. The three-way valve 6 is connected to an external controller, enabling it to control only one of the slurry pipe 4 and the air supply pipe 5 to be in a connected state. The grouting assembly 10... The grout tank and suction pump are existing technologies, and this application does not improve upon them. Therefore, it is not necessary to disclose their specific mechanical and circuit structures, and this does not affect the integrity of this application. The first solenoid valve 9, grouting assembly 10, second solenoid valve 14, pressure sensor 15, distance sensor 16, air pump 17 and other electrical components are all connected to an external controller. The above-mentioned electrical components and external controller are existing technologies, and this application does not improve upon them. Therefore, it is not necessary to disclose their specific mechanical and circuit structures, and this does not affect the integrity of this application.

[0022] It should be noted that, in actual use, this application involves ventilating before grouting, at which time the bottom of the sleeve is ventilated via a method such as... Figure 1The first sealing element is used for sealing, and the cleaning element 20 is located inside the sleeve. When grouting begins, the reinforcing bars are placed into both ends of the sleeve, and both ends are sealed by the second sealing element. The first and second sealing elements can be rubber discs or other structural components with sealing functions, which will not be described in detail in this embodiment. The first and second sealing elements are detachably connected to the sleeve. Specifically, snap-fit ​​assembly or bolt connection can be selected, which will not be specifically limited in this embodiment.

[0023] In practical application, this embodiment uses the sleeve positioning member 2 to fix the sleeve, and the bottom of the sleeve is sealed by the first sealing member. In the initial state, the cleaning member 20 is located at the bottom of the sleeve and is in contact with the inner wall of the sleeve. Figure 3As shown, at this time, the three-way valve 6 is adjusted so that the air supply pipe 5 is in the connected state and the slurry pipe 4 is in the closed state. At the same time, the first solenoid valve 9 and the second solenoid valve 14 are both in the open state. After the air pump 17 is started, air enters the sleeve through the top of the sleeve, then enters the first air box 11 through the grouting pipe 8, then enters the second air box 12 through the connecting pipe 13, and then enters the grouting hole of the sleeve through the air supply pipe 5. The airflow in the air supply pipe 5 will trigger the transmission component 21. The transmission component 21 can drive the cleaning component 20 to rise, so as to scrape the impurities on the inner wall of the sleeve. The distance sensor 16 measures the distance of the cleaning component 20. When the cleaning component 20 moves above the grouting hole and below the grout outlet hole, the airflow entering the grouting hole of the sleeve through the air supply pipe 5 can push the cleaning component 20 upward. By controlling the parameters of the air pump 17 and the transmission component 21, the cleaning component 20 can rise steadily and uniformly at a preset speed. During this process, the cleaning component 20 can scrape off impurities and dirt from the inner wall of the sleeve, and the airflow can also purge the pipeline, facilitating the cleaning and collection of impurities and dirt inside the pipeline. This achieves the removal of impurities from the inner wall of the sleeve and the inside of the pipeline before grouting, avoiding the impact of impurities inside the sleeve. This addresses the issue of grout filling degree and prevents inaccurate data from impurities affecting the measured air pressure during grouting. When the cleaning component 20 moves above the grout outlet, the air at the top of the sleeve can no longer enter the grouting pipe 8 through the outlet. At this time, under the action of the air pump 17, a circulating air path is formed between the inside of the sleeve, the grouting pipe 8, the first air box 11, the connecting pipe 13, the second air box 12, and the air supply pipe 5, which can prolong the airflow purging and cleaning time, allowing stubborn impurities inside the sleeve and in the pipeline to be blown off. After cleaning, the first sealing component is removed, and the cleaning component 20 is moved out of the sleeve, and then the reinforcing steel is... The sleeve is inserted into the casing, and both ends of the sleeve are sealed by the second sealing element. At this time, the three-way valve 6 is adjusted to make the grout pipe 4 open and the air supply pipe 5 closed. At the same time, the first solenoid valve 9 is opened and the second solenoid valve 14 is closed. Then the grouting component 10 can grout the sleeve through the grout pipe 4. The air in the sleeve enters the first air box 11 through the grouting pipe 8. The pressure sensor 15 can measure the air pressure. When the air pressure reaches the threshold, it means that the grout in the sleeve is full. Then the grouting component 10 stops grouting. In this way, the grouting and fullness detection of the sleeve can be realized.

[0024] like Figures 1-3 As shown, in a preferred embodiment of the present invention, the air pump 17 is connected to the auxiliary air pipe 18 that runs through the second air box 12, and a third solenoid valve 19 is provided on the auxiliary air pipe 18. The third solenoid valve 19 is connected to the distance sensor 16.

[0025] In one embodiment, the auxiliary air pipe 18 is provided with an activated carbon layer, which can filter the external air entering the second air box 12 through the auxiliary air pipe 18; the third solenoid valve 19 is connected to an external controller. The third solenoid valve 19 is prior art, and this application has not improved it. Therefore, it is not necessary to disclose its specific mechanical structure and circuit structure, and it does not affect the integrity of this application.

[0026] In practical application, when the cleaning component 20 moves above the slurry outlet, and the airflow circulates in the circulating air path for a period of time, the third solenoid valve 19 is opened, and the auxiliary air pipe 18 can input external air into the circulating air path. In conjunction with the transmission component 21, the cleaning component 20 can rise again until it is lifted off the sleeve. In this way, the inner wall of the top of the sleeve can be cleaned, and the cleaning component 20 can be automatically removed. While improving the cleaning effect, the cleaning component 20 is automatically separated from the sleeve.

[0027] like Figures 1-3 As shown, in a preferred embodiment of the present invention, the first air box 11 is connected to the exhaust pipe 25, and a fourth solenoid valve 26 is provided on the exhaust pipe 25.

[0028] In one embodiment, the fourth solenoid valve 26 is connected to an external controller. The fourth solenoid valve 26 is prior art, and this application has not improved it. Therefore, it is not necessary to disclose its specific mechanical structure and circuit structure, and this does not affect the integrity of this application.

[0029] In practical application, after grouting is completed, opening the fourth solenoid valve 26 will release the gas collected in the first gas box 11.

[0030] like Figures 1-7 As shown, in a preferred embodiment of the present invention, both the slurry pipe 4 and the gas pipe 5 are equipped with a pressure pump 7.

[0031] In one embodiment, the pressurizing pump 7 is connected to an external controller. The pressurizing pump 7 is prior art, and this application has not improved it. Therefore, it is not necessary to disclose its specific mechanical structure and circuit structure, and this does not affect the integrity of this application.

[0032] In practical applications, the addition of the pressure pump 7 in this embodiment can improve the fluidity of gas or slurry, thereby enhancing the applicability of the device.

[0033] like Figures 1-7 As shown, in a preferred embodiment of the present invention, the cleaning component 20 includes: The scraper 2001 is slidably installed inside the sleeve, and its edge is in contact with the inner wall of the sleeve. The scraper 2001 is connected to the positioning disk 22 through the connecting rod 2002, and the connecting rod 2002 is a telescopic structure. The transmission rod 2005 is connected to the transmission assembly 21 and is connected to the positioning plate 22 via a first elastic element; and The locking block 2006 engages and slides with the locking groove 2007 opened in the scraper 2001, and the locking block 2006 is fixedly connected to the transmission rod 2005.

[0034] In one embodiment, the telescopic structure is a structure composed of nested multi-stage tubular components. In practical applications, a gear and rack structure or an electric telescopic rod structure can also be used. This embodiment does not impose specific limitations on this structure. The first elastic element can be a spring, or it can be replaced by other elastic components, such as silicone pillars, spring sheets, etc. This embodiment does not impose specific limitations on this structure.

[0035] In practical application, when the transmission component 21 is triggered by the airflow in the air supply pipe 5, its output end drives the locking block 2006 to rise, then the first elastic element contracts, and the scraper 2001 can rise and scrape off the impurities on the inner wall of the sleeve.

[0036] In another embodiment, during actual use, the scraper 2001 is provided with a threaded groove, and a threaded rod is fixed on the positioning plate 22. The threaded rod is connected to the scraper 2001 by a thread, and the connecting rod 2002 is rotatably connected to the scraper 2001. Thus, the scraper 2001 can rotate when it rises, so that the inside of the sleeve can be rotated and wiped. Before grouting begins, the screw is disassembled and removed from the sleeve.

[0037] like Figures 3-7 As shown, in a preferred embodiment of the present invention, the cleaning component 20 further includes a sponge disc 2003 located below the scraper disc 2001, and the sponge disc 2003 is coaxially fixedly connected to the scraper disc 2001 via a shaft 2004.

[0038] In one embodiment, the sponge disc 2003 is soaked in cleaning agent, and the sponge disc 2003 is in close contact with the inner wall of the sleeve.

[0039] In practical application, when the scraper 2001 rises, it will cause the sponge disc 2003 to rise synchronously. The sponge disc 2003 can wipe away impurities from the inner wall of the sleeve; the initial state is as follows: Figure 3As shown, at this time, the sponge disc 2003 is located at the bottom of the sleeve, and the grouting hole is located between the scraper disc 2001 and the sponge disc 2003. At this time, the airflow entering from the grouting hole can push the scraper disc 2001 to rise. With the help of the transmission component 21, the scraper disc 2001 and the sponge disc 2003 can be controlled to rise smoothly, and the scraper disc 2001 will not lose power due to the switching of the air path when the airflow is controlled by a single airflow.

[0040] like Figures 3-5 As shown, in a preferred embodiment of the present invention, both the scraper 2001 and the sponge disc 2003 are provided with a plurality of vertically arranged ventilation holes 2008, and the diameter of the ventilation holes 2008 increases from high to low along their axial direction. A screen is provided inside the ventilation holes 2008.

[0041] In practical application, the ventilation hole 2008 in this embodiment can control the resistance of the scraper 2001 as it rises. In actual use, the minimum diameter of the scraper 2001 is set to 0.5 mm and the maximum diameter to 1 mm. This can prevent the scraper 2001 from rising too fast and failing to effectively scrape off impurities while raising it. In addition, the ventilation hole 2008 can intercept impurities, preventing them from flying around in the circulation pipeline and failing to be effectively collected or impacting structural components and causing damage to the components.

[0042] like Figures 1-7 As shown, in a preferred embodiment of the present invention, the transmission assembly 21 includes: The main shaft 2101 is rotatably mounted on the base 1, and a gear 2102 is coaxially fixedly mounted on it; The rack 2103 is slidably mounted on the positioning plate 22 and the two are connected by a second elastic element. The rack 2103 is vertically arranged, meshes with the gear 2102, and is fixedly connected to the transmission rod 2005. A drive shaft 2104 is rotatably mounted on a base 1 and is connected to a main shaft 2101 via a belt 2106; and Impeller 2105 is coaxially connected to power shaft 2104 and the two are linked together. Impeller 2105 is located inside gas transmission pipe 5.

[0043] In one embodiment, the second elastic element can be a spring, or other elastic components such as silicone pillars or spring sheets can be used instead. No specific limitations are made in this embodiment.

[0044] In practical application, when the gas flows in the gas pipe 5, it impacts the impeller 2105, causing it to rotate. The power shaft 2104 rotates synchronously, which drives the main shaft 2101 to rotate synchronously via the belt 2106. This causes the gear 2102 to rotate, thereby driving the rack 2103 to rise, which in turn raises the transmission rod 2005. As a result, the scraper 2001 can rise to clean the inner wall of the sleeve.

[0045] like Figures 1-7 As shown, in a preferred embodiment of the present invention, the transmission assembly 21 further includes a drive source 23 mounted on the base 1, and the drive source 23 is used to drive the positioning disk 22 to translate. The positioning disk 22 is slidably mounted on the base 1 and arranged horizontally. The main shaft 2101 and the power shaft 2104 are respectively connected to the base 1 through a first telescopic member 2107 and a second telescopic member 2108, and both the first telescopic member 2107 and the second telescopic member 2108 are rotatably mounted on the base 1. The central shaft of the power shaft 2104 is connected to the central shaft of the impeller 2105 through a third telescopic member 2109. The first telescopic member 2107, the second telescopic member 2108 and the third telescopic member 2109 are all telescopic structures.

[0046] In one embodiment, the drive source 23 may be a hydraulic cylinder, a pneumatic cylinder, or other mechanisms capable of linear motion. This embodiment does not impose specific limitations on these components.

[0047] It should be noted that the impeller 2105 is rotatably installed inside the gas transmission pipe 5, and the third telescopic component 2109 is installed through the gas transmission pipe 5, with a sealing ring provided in the through part.

[0048] In practical application of this embodiment, when the distance sensor 16 detects that the cleaning component 20 has been lifted off the sleeve, the drive source 23 drives the positioning disk 22 to translate, as shown below. Figure 7 As shown, at this time, the first telescopic component 2107 and the second telescopic component 2108 retract synchronously, and the third telescopic component 2109 extends, which allows the positioning plate 22, cleaning component 20, main shaft 2101, gear 2102, rack 2103, power shaft 2104 and belt 2106 to move synchronously, so that the end of the sleeve can be completely opened to facilitate the insertion of reinforcing bars and the installation of the second sealing component; after the drive source 23 drives the positioning plate 22 to move, the external controller adjusts the three-way valve 6 to make the slurry pipe 4 connected and the air supply pipe 5 closed, and at the same time adjusts the first solenoid valve 9 to be in the open state and the second solenoid valve 14 to be in the closed state, and then opens the grouting assembly 10 to grout the sleeve.

[0049] like Figures 1-3 As shown, in a preferred embodiment of the present invention, a collection cylinder 24 is provided on the infusion pipe 8, and a filter screen is provided at the connection between the infusion pipe 8 and the first air box 11.

[0050] In practical application, the collection cylinder 24 can collect a small amount of slurry that overflows or splashes from the slurry outlet, preventing this part of the slurry from entering the first air box 11. The filter screen can not only intercept the overflowing slurry from entering the first air box 11, but also intercept impurities blown by the airflow. The impurities can be uniformly treated by removing the filter screen before grouting.

[0051] Working principle of the invention: The above embodiments of the invention provide a prefabricated building sleeve grouting fullness detection device. The sleeve is fixed by the sleeve positioning member 2, and the bottom of the sleeve is sealed by the first sealing member. The three-way valve 6 is adjusted so that the air supply pipe 5 is in the connected state and the grout pipe 4 is in the closed state. At the same time, the first solenoid valve 9 and the second solenoid valve 14 are both in the open state. After the air pump 17 is started, air enters the sleeve through the top of the sleeve, then enters the first air box 11 through the grouting pipe 8, then enters the second air box 12 through the connecting pipe 13, and then enters the grouting hole of the sleeve through the air supply pipe 5. The airflow in the air supply pipe 5 will trigger the transmission component 21. The transmission component 21 can drive the cleaning member 20 to rise to scrape off the impurities on the inner wall of the sleeve; through The distance sensor 16 measures the upward displacement of the cleaning component 20. When the cleaning component 20 moves above the grouting hole and below the grout outlet hole, the airflow entering the grouting hole of the sleeve through the air supply pipe 5 can push the cleaning component 20 upward. By controlling the parameters of the air pump 17 and the transmission component 21, the cleaning component 20 can rise steadily and uniformly at a preset speed. During this process, the cleaning component 20 can scrape off impurities and dirt from the inner wall of the sleeve, and the airflow can also purify the pipeline, facilitating the cleaning and collection of impurities and dirt inside the pipeline. This achieves the removal of impurities from the inner wall of the sleeve and the inside of the pipeline before grouting, avoiding the problem of impurities inside the sleeve affecting the grouting filling degree, and also avoiding the inaccuracy of the measured air pressure during grouting due to the influence of impurities.

[0052] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
