Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a system and method for removing bulging concrete. Background Technology

[0002] During concrete pouring, factors such as formwork erection, rebar tying, concrete foaming agent, and excessive pouring height may cause high pouring pressure, which in turn causes the entire formwork to deform and expand. This phenomenon is called formwork bulging.

[0003] Reference Figure 1 After the formwork is removed from the cast-in-place concrete, the raised portion on the surface is called bulging concrete. Although many technical solutions have been proposed in the existing technology to avoid bulging concrete, such as increasing the quality inspection and acceptance of formwork engineering, improving the cast-in-place concrete pouring process, and improving the level of construction site management, bulging still occurs during the concrete pouring process, at which point the bulging formwork needs to be removed.

[0004] Currently, for cases of bulging concrete, the construction site adopts the method of manually removing the bulging concrete after the formwork is removed. This method is not only labor-intensive and time-consuming with low efficiency, but also poses risks to the safety and health of construction workers due to noise and dust pollution and the high-level removal. Summary of the Invention

[0005] In order to improve the efficiency of demolition of bulging concrete and reduce the probability of potential safety and health hazards to construction workers, this application provides a system and method for demolishing bulging concrete.

[0006] On the one hand, the bulging concrete removal system provided in this application adopts the following technical solution:

[0007] A system and method for removing bulging concrete formwork includes a bulging monitoring device and a bulging concrete removal device. The bulging monitoring device monitors and locates the bulging position and draws a bulging diagram. The bulging monitoring device includes latitude and longitude lines, a deformation monitoring unit, and a data analysis module. The latitude and longitude lines are evenly distributed on the outside of the cast-in-place concrete formwork, and the deformation monitoring unit is set at one end of each latitude and longitude line. The deformation monitoring unit and the data analysis module are connected wirelessly. The bulging concrete removal device drills and cuts the bulging formwork according to the bulging diagram. The bulging concrete removal device includes a device shell, a mobile power supply, a drive motor, a transmission rod, a drill rod disc, and drill rods. The mobile power supply is connected to the drive motor, the output shaft of the drive motor is connected to the transmission rod, and the end of the transmission rod away from the drive motor is connected to the drill rod disc. Multiple drill rods are arranged at intervals at the bottom of the drill rod disc. The drive motor, transmission rod, and drill rod disc are all located inside the device shell, while the mobile power supply and drill rods are located outside the device shell.

[0008] By adopting the above technical solution, bulging monitoring equipment is installed on the formwork surface, which can monitor the time, location, and size of bulging in real time. This facilitates real-time safety monitoring on the construction site and provides technical support for controlling the quality of cast-in-place concrete. The effective combination of latitude and longitude lines and deformation monitoring units, through the bulging concrete removal system's bulging monitoring equipment, not only achieves real-time monitoring of cast-in-place concrete bulging, effectively avoiding quality accidents such as concrete bursting and leakage due to untimely detection of bulging, but also provides technical parameters and bulging diagrams for removal after bulging. This allows the bulging concrete removal equipment to remove the bulging concrete safely and environmentally in a timely and effective manner. The cast-in-place concrete bulging concrete removal method improves the efficiency of bulging removal and reduces the probability of potential safety and health hazards for construction workers.

[0009] Optionally, the deformation monitoring unit includes a movable slot, a positioning sensor, and a base station. The movable slot is fixed on the template, and the top of the movable slot is used to tighten the warp and weft lines. The interior of the movable slot contains untightened warp and weft lines. The positioning sensor is located on the warp and weft lines at the top of the movable slot. The positioning sensor is wirelessly connected to the base station, and the base station is wirelessly connected to the data analysis module.

[0010] By adopting the above technical solution, the outline of the concrete module is copied using latitude and longitude lines. The combination of movable slots and positioning sensors not only achieves accurate positioning of the bulging position, but also measures the size of the bulging concrete by measuring the displacement of the positioning sensors. Data is obtained through wireless connection between the base station and the data analysis module.

[0011] Optionally, the warp and weft threads are made of high-strength steel wire, including warp threads and weft threads, with a spacing of 200mm between each warp thread and each weft thread.

[0012] By adopting the above technical solution, due to the high strength of the high-strength steel wire, the warp high-strength steel wire bundles and weft fiber bundles are woven together during use, thereby fixing the high-strength steel wire firmly and preventing the weft threads from skewing and the high-strength steel wire bundles from coming apart, which further improves the efficiency of removing the concrete from the bulging formwork.

[0013] Optionally, the power bank is a rechargeable lithium battery.

[0014] By adopting the above technical solution, the power bank is set as a rechargeable lithium battery, which makes the power bank easy to move and can be charged at the same time, avoiding the need to replace the battery at intervals, and making the power bank more convenient to set up.

[0015] Optionally, the drill rod disc is circular, and multiple drill rod holes are opened on the drill rod disc. The multiple drill rod holes are arranged in concentric circles, and the drill rod is connected to the transmission rod through the drill rod holes.

[0016] By adopting the above technical solution, when in use, the drill rod is connected to the transmission rod. At this time, the mobile power supply and drive motor are started, so that the output shaft of the drive motor drives the transmission rod and the drill rod to rotate, thereby realizing the demolition and cutting of concrete.

[0017] Optionally, the drill rod includes a drilling rod and a cutting rod, wherein the drilling rod is configured as a spiral drill rod with a solid drill bit, and the cutting rod is configured as a smooth drill rod with a spiral elastic cutting head.

[0018] By adopting the above technical solution and using the bulging concrete demolition equipment, technical equipment is provided for the mechanical demolition of bulging concrete; the bulging concrete demolition equipment has both drilling and cutting functions, which effectively reduces the equipment cost for demolishing bulging concrete.

[0019] Optionally, the diameter of the drill bit is 0.5-3.5m.

[0020] By adopting the above technical solution, the diameter of the drilling disc is set to 0.5-3.5 meters. If the diameter is too small, the demolition efficiency will be reduced. If the diameter is too large, it will be difficult for construction workers to operate and difficult for them to observe the demolition situation.

[0021] On the other hand, the bulging concrete removal system and method provided in this application adopts the following technical solution:

[0022] Optional steps include:

[0023] S1: Arrange the latitude and longitude lines evenly every 200mm on the outside of the cast-in-place concrete formwork, then fix one end of the latitude and longitude lines to the formwork, and connect the other end of the latitude and longitude lines to the positioning sensor. The base station is installed at the four corners of the formwork.

[0024] S2: Concrete pouring. The data analysis module monitors the changes in the position of the positioning sensor before the initial setting of the concrete in real time, and draws the bulging diagram based on the changes in the position of the positioning sensor.

[0025] S3: According to the bulging diagram, adjust the size of the drill rod disc of the bulging concrete removal equipment so that the size of the drill rod disc matches the bulging formwork. Figure 1 To;

[0026] S4: After the initial setting and before the final setting of the concrete, use a formwork demolition equipment with a drilling rod to drill holes at the bulging part of the formwork. After drilling, insert reinforcing bars into the holes and seal the ends.

[0027] S5: After the concrete has set, remove the reinforcing bars from the drilled hole. Use a concrete demolition equipment with a cutting drill rod to go deep into the bottom of the drilled hole and cut the concrete inside the formwork. After cutting, temporarily fix the bulging part and remove it together with the formwork when it is demolished.

[0028] By adopting the above technical solution, drilling is performed after the initial setting and before the final setting of the concrete. Reinforcing bars are inserted after drilling, and the ends are sealed. This effectively avoids concrete leakage caused by drilling before initial setting, achieving the technical effect of simultaneously reducing the mechanical strength and overall stiffness of the bulging concrete at a lower strength level. This creates favorable conditions for cutting and removing the bulging concrete. Because the bulging concrete is drilled before initial setting, cutting it after final setting significantly reduces the cutting surface and workload, decreases wear on the drill bit, and improves the efficiency of cutting and removing the bulging concrete.

[0029] Optionally, the data analysis module monitors the position changes of the positioning sensor before the concrete initially sets in real time, and draws a bulging diagram based on the position changes of the positioning sensor, including the following steps: the bulging diagram is a removable bulging diagram, and the volume of the removable bulging diagram is greater than 20 square meters.

[0030] By adopting the above technical solution and utilizing the volume and location information displayed by the three-dimensional bulging concrete diagram, the classification and on-site demolition efficiency of bulging concrete removal is improved, and the safety accidents caused by searching for bulging concrete are effectively reduced.

[0031] Optionally, the reinforcing bars in the borehole are removed, and a formwork demolition device with a cutting drill rod is used to reach the bottom of the borehole and cut the concrete inside the formwork. This includes the following steps: cutting is carried out within 0.5-3 hours after the concrete has set.

[0032] By adopting the above technical solution, the concrete hardness is further increased due to the excessive time after final setting. Therefore, cutting should be carried out within 0.5-3 hours after the concrete has set, while ensuring the efficiency of concrete cutting.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. By setting up bulging concrete removal equipment, latitude and longitude lines, deformation monitoring units, data analysis modules, and templates, and installing bulging monitoring equipment on the template surface, the system can monitor the time, location, and size of bulging in real time. This facilitates real-time safety monitoring of the construction site and provides technical support for controlling the quality of cast-in-place concrete. The effective combination of latitude and longitude lines and deformation monitoring units, through the bulging concrete removal system's bulging monitoring equipment, not only achieves real-time monitoring of cast-in-place concrete bulging, effectively preventing quality accidents such as concrete bursting and leakage due to untimely detection of bulging, but also provides technical parameters and bulging diagrams for subsequent removal, enabling timely, effective, safe, and environmentally friendly removal of bulging concrete. The method used for removing bulging concrete improves the efficiency of bulging removal and reduces the probability of safety and health hazards for construction workers.

[0035] 2. By setting up a movable slot, positioning sensor, base station, equipment shell, mobile power supply, drive motor and transmission rod, the outline of the concrete module is copied through the latitude and longitude lines. The combination of movable slot and positioning sensor not only achieves accurate positioning of the expansion position, but also measures the size of the expansion concrete by the displacement of the positioning sensor. The data is obtained by wirelessly connecting the base station and the data analysis module. Attached Figure Description

[0045] The following is in conjunction with the appendix Figure 2-8 This application will be described in further detail.

[0046] On the one hand, embodiments of this application disclose a system for removing bulging concrete.

[0047] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A system for removing bulging concrete formwork includes a bulging monitoring device and a bulging concrete 12 removal device 1. The bulging monitoring device monitors and locates the bulging position and draws a bulging diagram. The bulging monitoring device includes latitude and longitude lines 11, deformation monitoring units 2, and a data analysis module 21. The latitude and longitude lines 11 are evenly distributed on the outside of the cast-in-place concrete formwork 211, and the deformation monitoring units 2 are set at one end of each latitude and longitude line 11. The deformation monitoring units 2 and the data analysis module 21 are connected wirelessly. The bulging concrete 12 removal device 1 drills and cuts the bulging formwork according to the bulging diagram. The device 1 includes a housing 225, a power supply 226, a drive motor 227, a transmission rod 228, a drill rod disc 229, and drill rods 3. The power supply 226 is connected to the drive motor 227. The output shaft of the drive motor 227 is connected to the transmission rod 228. The end of the transmission rod 228 away from the drive motor 227 is connected to the drill rod disc 229. Multiple drill rods 3 are provided and spaced apart at the bottom of the drill rod disc 229. The drive motor 227, the transmission rod 228, and the drill rod disc 229 are all located inside the housing 225, while the power supply 226 and the drill rods 3 are located outside the housing 225.

[0048] A bulging monitoring device is installed on the surface of template 211, which can monitor the time, location, and size of bulging in real time, facilitating real-time safety monitoring of the construction site and providing technical support for controlling the quality of cast-in-place concrete. The effective combination of latitude and longitude lines 11 and deformation monitoring unit 2, through the bulging concrete removal system's bulging monitoring device, not only achieves real-time monitoring of cast-in-place concrete bulging, effectively avoiding quality accidents such as concrete bursting and leakage caused by untimely detection of bulging, but also provides technical parameters and bulging diagrams for removal after bulging, enabling the bulging concrete 12 removal equipment 1 to remove the bulging concrete 12 safely and environmentally in a timely and effective manner. The cast-in-place concrete bulging concrete 12 removal method improves the efficiency of bulging removal and reduces the probability of potential safety and health hazards to construction workers.

[0049] The power bank 226 is a rechargeable lithium battery. The warp and weft threads 11 are made of high-strength steel wire, including warp threads 111 and weft threads 112, with a spacing of 200mm between each warp thread 111 and each weft thread 112.

[0050] Due to the high strength of high-strength steel wire, during use, the warp high-strength steel wire bundles are woven with the weft fiber bundles to firmly fix the high-strength steel wires, making it less likely for the weft yarn 112 to become skewed or for the high-strength steel wire bundles to detach, further improving the efficiency of concrete removal from the bulging formwork. The portable power bank 226 is equipped with a rechargeable lithium battery, allowing it to be easily moved while being charged, eliminating the need for periodic battery replacements and making its setup more convenient.

[0051] Reference Figure 2 and Figure 4 The deformation monitoring unit 2 includes a movable slot 222, a positioning sensor 223, and a base station 224. The movable slot 222 is fixed on the template 211. The top of the movable slot 222 is used to tighten the warp and weft threads 11. The movable slot 222 contains untightened warp and weft threads 11. The positioning sensor 223 is located on the warp and weft threads 11 at the top of the movable slot 222. The positioning sensor 223 is wirelessly connected to the base station 224. The base station 224 is wirelessly connected to the data analysis module 21.

[0052] The outline of the concrete module is copied through the latitude and longitude lines 11. The combination of the movable slot 222 and the positioning sensor 223 not only achieves accurate positioning of the bulging position, but also measures the size of the bulging concrete 12 by measuring the displacement of the positioning sensor 223. The data is obtained by wirelessly connecting the base station 224 and the data analysis module 21.

[0053] Reference Figure 5 and Figure 6The drill rod disc 229 is circular, and multiple drill rod holes 4 are formed on the drill rod disc 229. The drill rod holes 4 are arranged concentrically, and the drill rod 3 is connected to the transmission rod 228 through the drill rod holes 4. The drill rod 3 includes a drilling rod and a cutting rod. The drilling rod is a spiral drill rod 8 with a solid drill bit 7, and the cutting rod is a smooth drill rod 10 with a spiral elastic cutting head 9. The diameter of the drill disc is 0.5-3.5m.

[0054] In use, the drill rod 3 is connected to the transmission rod 228. Then, the mobile power supply 226 and drive motor 227 are activated, causing the output shaft of the drive motor 227 to rotate the transmission rod 228 and the drill rod 3, thus achieving the demolition and cutting of the concrete. The use of the bulging concrete 12 demolition equipment 1 provides technical equipment for the mechanical demolition of bulging concrete 12. The bulging concrete 12 demolition equipment 1 has both drilling and cutting functions, effectively reducing the equipment cost for demolishing bulging concrete 12. The diameter of the drilling disc is set to 0.5-3.5 meters. If the diameter is too small, the demolition efficiency will be reduced; if the diameter is too large, it will be difficult for construction workers to operate and observe the demolition process.

[0055] The implementation principle of the bulging concrete removal system of this application embodiment is as follows: A bulging monitoring device is installed on the surface of the formwork 211, which can monitor the time, location, and size of bulging in real time, facilitating real-time safety monitoring of the construction site and providing technical support for controlling the quality of cast-in-place concrete. The effective combination of the latitude and longitude lines 11 and the deformation monitoring unit 2, through the bulging concrete removal system's bulging monitoring device, not only achieves real-time monitoring of cast-in-place concrete bulging, effectively avoiding quality accidents such as concrete bursting and leakage due to untimely detection of bulging, but also provides technical parameters and bulging diagrams for removal after bulging, enabling the bulging concrete 12 removal equipment 1 to remove the bulging concrete 12 safely and environmentally in a timely and effective manner. The method used for removing bulging concrete 12 improves the removal efficiency of bulging and reduces the probability of potential safety and health hazards to construction workers.

[0056] Reference Figure 7 and Figure 8 On the other hand, this application provides a method for removing bulging concrete, comprising the steps of:

[0057] S1: The latitude and longitude lines 11 are evenly distributed on the outside of the cast-in-place concrete formwork 211 every 200mm. One end of the latitude and longitude lines 11 is fixed on the formwork 211, and the other end of the latitude and longitude lines 11 is connected to the positioning sensor 223. The base station 224 is installed at the four corners of the formwork 211.

[0058] S2: Pour concrete. The data analysis module 21 monitors the position change of the positioning sensor 223 before the concrete sets in real time and draws the bulging diagram based on the position change of the positioning sensor 223.

[0059] S3: According to the bulging formwork diagram, adjust the size of the drill rod disc 229 of the demolition equipment 12 for the bulging concrete 12, so that the size of the drill rod disc 229 matches the size of the formwork 211 for bulging. Figure 1 To;

[0060] S4: After the initial setting and before the final setting of the concrete, use the formwork demolition equipment 1 with drilling rod 3 to drill holes at the formwork 211 at the bulging part. After drilling, insert the reinforcing bar 14 into the hole and seal the end.

[0061] S5: After the concrete has set, remove the reinforcing bar 14 from the borehole. Use the bulging concrete 12 removal equipment 1 with cutting drill rod 3 to go deep into the bottom of the borehole and cut the concrete inside the bulging formwork 211. After cutting, temporarily fix the bulging part and remove it together with the formwork 211 when it is removed.

[0062] Drilling is performed after the initial setting of the concrete but before its final setting. Reinforcing bars 11 are inserted into the drilled holes, and the ends are sealed. This effectively prevents concrete leakage caused by drilling before initial setting, achieving the technical effect of simultaneously reducing the mechanical strength and overall stiffness of the bulging concrete 12 at a lower strength level. This creates favorable conditions for cutting and removing the bulging concrete 12. Because holes are drilled in the bulging concrete 12 before initial setting, cutting it after final setting significantly reduces the cutting surface and workload, decreases wear on the drill bit, and improves the efficiency of cutting and removing the bulging concrete 12.

[0063] The formwork plan is a removable formwork plan, with a volume greater than 20 square meters. Cutting should be carried out within 0.5-3 hours after the concrete has fully set.

[0064] By utilizing the volume and location information displayed in the 3D bulging formwork diagram, the classification and on-site removal efficiency of bulging concrete 12 are improved, and the safety accidents caused by locating bulging concrete 12 are effectively reduced. To avoid the concrete hardening further due to excessive time after final setting, cutting should be carried out within 0.5-3 hours after the concrete has set, while ensuring the efficiency of concrete cutting.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
