[0003] The prior art with announcement number CN114458044A discloses a method for repairing fine cracks in buildings, which mainly includes building cleaning, point drilling, cleaning, observation and grouting, building grinding and leveling. In the point drilling process, vertical drilling is first performed at the edge of the crack, and a new hole is opened at a position 40-50CM along the crack with the hole as the starting point. At the same time, at one side of all the openings, a hole-opening device is placed on the surface of the building in an inclined state to open another hole, and then each hole is grouted in turn so that the slurry fills the hole to achieve the repair effect.

[0004] However, the existing building repair method still has obvious defects. For example, it is necessary to frequently drill holes in the building, which can easily cause secondary damage to the building. In addition, the slurry can only flow into the holes passively.

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 is a schematic diagram of a building repair device provided by an embodiment of the present invention during a repair process; Figure 2 It is a schematic flow chart of the magnetic control repair method provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] In order to solve the technical problems that the building repair methods in the prior art need to frequently drill holes in the buildings, which may easily cause secondary damage to the buildings; in addition, the slurry can only flow into the holes passively, and for some holes with more complicated paths, the slurry may not be able to flow in, resulting in poor repair effect, the present invention provides a magnetically controlled repair method, which can achieve directional control of magnetic glue so that the magnetic glue can fill the pores of the building, with high repair efficiency and guaranteed repair quality.

[0020] It should be noted that the magnetic control repair method described in the present invention is used for but not limited to wooden buildings, etc. For the convenience of explanation, in the present invention, only the application of the magnetic control repair method to wooden buildings is used as an example for explanation. The principle of applying the magnetic control repair method to other types of equipment is essentially the same as the principle of applying it to wooden buildings, and will not be repeated here.

[0021] See also Figure 1 , Figure 1 This is a schematic diagram of the steps of a magnetron repair method in one embodiment of the present invention. The magnetron repair method includes the following steps: In the first step, the hard debris on the surface of the building 1 is first removed using tools, and the dust and dirt on the surface of the building 1 are cleaned with clean water to create a clean construction environment and prevent dust from entering the pores 11 of the building 1 and affecting the repair effect.

[0022] In one embodiment, before using clean water to clean the building, a vacuum machine can be used to suck or blow air to the pores 11 of the building 1 to drive out the debris or dust inside the pores 11. In this embodiment, the working mode of the vacuum machine can be switched according to the size of the debris in the pores 11 and the structure of the pores 11. If the debris is close to the outlet of the pores 11, the pores 11 can be blown to blow the debris out of the outlet of the pores 11. If the debris is close to the entrance of the pores 11, the nozzle of the vacuum machine can be inserted into the entrance of the pores 11 to suck the debris, so as to quickly clean up the debris in the pores 11.

[0023] The second step is to use an infrared detector to illuminate the building 1 so that the path of the pores 11 inside the building 1 is presented; the infrared detector can emit infrared rays to the building 1, and based on the thermal imaging principle of temperature difference, the pores inside the building 1 are presented, so that the maintenance personnel can know the damage inside the building 1 and formulate a maintenance plan. The infrared detector includes a display screen and an infrared transmitter connected to each other. The infrared transmitter is used to emit infrared rays to the building and transmit the detected image of the building 1 to the display screen for the maintenance personnel to refer to.

[0024] The third step is to prepare the magnetic glue and use the syringe 4 to inject the magnetic glue 2 into the pores 11 of the building 1; in this step, a plan can be specified based on the pore path detected by the infrared detector, such as which pore 11 to inject the magnetic glue 2 from will be more conducive to filling the pore 11 with the magnetic glue, and the order of injecting the pores 11, etc.

[0025] The fourth step is to use the magnetic coil 31 to be close to the building 1 to magnetically attract the magnetic glue 2, and move the magnetic coil 31 according to the path of the pores 11, so that the magnetic coil 31 drives the magnetic glue 2 to flow in the pores 11 in a directional manner through magnetic attraction to fill the pores. In the process of moving the magnetic coil 31, the display screen of the infrared detector can be observed at the same time to see the flow position of the magnetic glue 2 and whether the pores 11 are filled, so as to assist the maintenance personnel to fill all the pores 11.

[0026] In one embodiment, the magnetic glue 2 includes polyurethane glue, magnetic fluid, Chinese herbal essential oil, adhesive, magnetic nanoparticles, ferroferric oxide and nano-active calcium carbonate. The polyurethane glue has good bonding force, strong plasticity, chemical resistance, resilience and excellent mechanical properties, so that the magnetic glue 2 can more fully fill the pores of the building 1. The Chinese herbal essential oil has the function of repairing wooden buildings and can also eliminate pests such as termites, and has a protective effect on the wooden building 1.

[0027] In one embodiment, see Figure 2 , the components of the magnetic glue 2 include 35-40 parts of the carbamate, 15-20 parts of the magnetic fluid, 4-6 parts of nano-active calcium carbonate, 5-10 parts of the adhesive, 10-15 parts of ferroferric oxide, 25-30 parts of magnetic nanoparticles, 3-5 parts of Chinese herbal essential oil, and 8-12 parts of the catalyst. After several tests, it was found that the proportion of each component was controlled within the range of this embodiment, and the obtained magnetic glue 2 not only had good magnetism, but also could maintain good magnetic attraction with the magnetic coil 31, and also had good insect repellent effect, which could prevent the building 1 from being eroded by insect pests again. The catalyst of this embodiment can be dibutyltin dilaurate.

[0028] In one of the embodiments, the configuration steps of the magnetic glue 2 are as follows: control the indoor ventilation, the room temperature is 20℃-30℃, the indoor humidity is 40%RH-60%RH, polyurethane glue, magnetic fluid, Chinese herbal essential oil, adhesive, magnetic powder, ferroferric oxide and light calcium carbonate are placed in the stirring tank of the blender, first manually stir clockwise for 7-9 minutes using a tool, and then use the blender's stirring paddle to automatically stir for 4-6 minutes to obtain the magnetic glue.

[0029] The present invention also provides a building repair device 3, comprising a magnetic coil 31 and a syringe 4, wherein the syringe 4 is used to store magnetic glue 2 and to inject the magnetic glue 2 into the pores of the building. The magnetic coil 31 can magnetically attract the magnetic glue 2 in the pores 11 when powered on, so that the magnetic coil 31 can drive the magnetic glue 2 to flow in the pores 11 of the building when moving, so that the magnetic glue 2 fills the pores 11.

[0030] Furthermore, the building repair device 3 also includes a sliding resistor, which is connected to the magnetic coil 31 and can adjust the magnetic size of the magnetic coil 31 during sliding to adjust the adsorption force between the magnetic coil 31 and the magnetic glue 2. Since the pores inside the building vary in size, for some pores with smaller spaces, it is necessary to increase the magnetism of the magnetic coil 31 to increase the magnetic attraction to the magnetic glue, so as to drive the magnetic glue 2 through the narrow pores. For pores with larger spaces, the magnetism of the magnetic coil 31 can be appropriately reduced to reduce the magnetic attraction to the magnetic glue 2.

[0031] In one embodiment, see Figure 2 The building repair device 3 also includes a housing 32, a power source and a universal wheel. The power source and the magnetic coil 31 and the power source are all arranged in the housing 32. The power source is connected to the magnetic coil 31 and is used to supply power to the magnetic coil 31 so that the magnetic coil 31 generates magnetism. The outward wheel is rotatably arranged at the bottom of the housing 32. In this embodiment, the building repair device 3 can roll on the ground through the universal wheel to adjust the position of the magnetic coil 31, and the adjustment is fast and labor-saving. In other embodiments, a handle can be set on the top of the housing 32, and the maintenance personnel can drive the magnetic coil 31 to move through the handle, thereby driving the magnetic glue 2 to flow and fill the pores 11.

[0032] In one embodiment, see Figure 2 After the pores 11 of the building are filled with the magnetic glue 2 , a SEM (scanning electron microscope) test or an XRD (X-ray diffraction) test is performed on the repaired building 1 to detect whether all the pores 11 of the building 1 are filled with the magnetic glue 2 .

[0033] In one embodiment, see Figure 2 The syringe 4 is provided with a pressurizer 41 and a pressure gauge 42. The pressurizer 41 is used to pressurize the magnetic glue 2, and the pressure gauge 42 is used to sense the air pressure inside the syringe 4. In this embodiment, the pressurizer 41 can be used to pressurize the syringe 4 to drive the magnetic glue 2 inside the syringe 4 to enter the pores 11 of the building 1 more and faster. The pressure gauge 42 can be used to monitor the air pressure inside the syringe 4, so that the maintenance personnel can adjust the pressurizer 41 to control the air pressure inside the syringe 4 within a suitable range.

[0034] In order to better understand the present invention, the following Figure 1 to Figure 2 The technical solution of the present invention is described in detail: The magnetic control repair method provided by the present invention does not need to drill holes in the building 1 when repairing the building 1, which can avoid secondary damage to the building 1. In addition, the magnetic glue 2 can be driven to flow in a directional manner by the magnetic attraction between the building repair device 3 and the magnetic glue 2, so that the magnetic glue 2 fills the pores of the building 1, the repair efficiency is high, and the repair quality can be guaranteed. The magnetic glue 2 itself has the effect of killing insects and preventing insects. After filling the pores 11 of the building, the magnetic glue 2 can also protect the building.
