Description

Technical Field

[0001] The present invention belongs to the technical field of concrete curing, and in particular relates to a concrete wall curing spray device and a use method thereof. Background Art

[0002] Concrete curing refers to providing hydration reaction conditions for concrete after it is molded, so that it gradually hardens under a certain humidity. Therefore, it is necessary to spray water on the concrete to achieve the humidity required for hardening, thereby obtaining good physical and mechanical properties and durability. The early curing of concrete is a "careful" construction process. The concept of "early curing as the main and material reduction as the auxiliary" is still the mainstream of concrete crack control. Current concrete manufacturers pursue higher early concrete strength benefits and often use cement with lower fineness. The concrete reaction rate is increased, and higher requirements are also put forward for the curing conditions of concrete. For example, the patent authorization announcement number is CN205189416U, which discloses a concrete wall curing spray device.

[0003] At present, the concrete beams and slabs of construction projects usually have good curing conditions for covering and moisturizing, while vertical components rely more on people's sense of responsibility. The automatic curing equipment on the outer side of the exterior wall can also be lifted layer by layer along with the main climbing frame. The application of technology is relatively common, while the automatic curing technology of the interior walls of buildings is relatively lagging. Most of them still rely on manual spraying of water to maintain the curing environment. Since the interior concrete walls are in a vertical state and the surface is relatively smooth, the sprayed water is difficult to retain in large quantities and is very easy to evaporate. This requires a low-volume and multiple-time spraying curing strategy for the interior concrete walls to meet the humidity conditions required for its hydration reaction. However, in actual operation, manual spraying is often difficult to be in place in time. After completing a spraying, the staff are often busy with other matters and cannot continue to pay attention to the dryness and wetness of the interior wall surface. As a result, the interior wall cannot be quickly sprayed again for moisturizing after the water evaporates and dries.

[0004] The direct consequence of this untimely maintenance is that the hydration reaction of the concrete inner wall is hindered due to lack of water, which in turn causes quality problems such as surface cracking, posing a challenge to the overall quality control of the project. At the same time, frequent manual operations not only greatly increase the labor intensity of the staff, but also seriously affect the efficiency and convenience of spray maintenance of the concrete inner wall.

[0017] A method for using a concrete wall maintenance spray device, the method comprising the following steps:

[0018] S1. When the inner concrete wall of a building needs to be cured after demolding, first select a corresponding number of concrete wall curing spray devices according to the position and area of ​​the inner concrete wall of the building, and position and install the concrete wall curing spray devices at the inner concrete wall of the building that needs to be cured. Then, arrange the outer cylinder vertically through the base, adjusting screw and top block, and then horizontally install the connecting cylinder of each spray mechanism in the first connecting groove of the corresponding spray mechanism, and horizontally install the second electric push rod in the second connecting groove;

[0019] S2. After the connecting tubes of the spraying mechanisms are installed horizontally in step S1, the spraying angles of the rotating seated spray heads of each spraying mechanism are adjusted so that the rotating seated spray heads in the multiple spraying mechanisms cooperate with each other to comprehensively and evenly spray the moisturizing liquid on the surface of the building's inner concrete wall. At the same time, the detection end of the electronic concrete hardness tester in the concrete hardness testing mechanism is arranged on the outside of the building's inner wall surface.

[0020] S3. After the multiple rotating seated sprinkler heads are fully positioned, they are connected in series to the water outlet of the electric regulating valve through multiple PVC soft water pipes. The water inlet of the electric regulating valve is connected to the permanent and temporary combined fire hydrant in the building through the PVC soft water pipe. Water is then supplied to the concrete wall maintenance sprinkler device through the permanent and temporary combined fire hydrant in the building.

[0021] S4. The PLC controller then controls the electric regulating valve to open, so that the water in the building's permanent and temporary fire hydrants is transported through PVC soft water pipes to the rotating seated sprinkler heads adjusted at various angles. The rotating seated sprinkler heads spray water onto the building's concrete walls. At the same time, to address the situation where the vertical state of the building's concrete walls results in insufficient spray water retention, the PLC controller controls the electric regulating valve to start spraying for 5 minutes every 2 hours, thereby providing continuous and reliable hydration reaction conditions for the concrete.

[0022] S5. When the concrete wall curing spray device is in use, the SIM card wireless camera can also remotely capture images of the curing spray site and transmit them back to the control room of the construction project. The SIM card wireless camera can freely rotate 360 ​​degrees to capture images, ensuring that staff can remotely and comprehensively understand the curing spray site conditions and monitor the curing spray effect of the building's concrete walls.

[0023] S6. In step S5, while the SIM card wireless camera is monitoring online, the water stains attached to the surface of the glass tube are scraped off by the cleaning component;

[0024] S7. During the first 2 minutes of each curing spraying of the building concrete inner wall, the PLC controller controls the concrete hardness detection mechanism and the auxiliary mechanism to automatically detect the hardness of the building concrete inner wall. At the same time, the electronic concrete hardness rebound tester can send the detected hardness value to the PLC controller in the form of an electrical signal. The PLC controller can control the opening of the electric regulating valve according to the surface hardness of the building concrete inner wall.

[0025] Compared with existing technologies, the advantages of a concrete wall maintenance spray device and its use method are:

[0026] 1. Through the provided adjusting screw and spraying mechanism, when the building concrete inner wall needs to be cured after demolding, first, a corresponding number of concrete wall curing spraying devices are selected according to the position and area of ​​the building concrete inner wall, and the concrete wall curing spraying device is positioned and installed at the building concrete inner wall that needs to be cured, then the height and angle of the multiple spraying mechanisms are adjusted and fixed through the first connecting ring, and the position of the rotating seated spraying head is adjusted through the connecting tube and the extension rod, and then the spraying angle of the rotating seated spraying head is adjusted through the adjusting rod, so that the rotating seated spraying heads in the multiple spraying mechanisms cooperate with each other to fully and evenly spray the moisturizing water on the surface of the building concrete inner wall, avoiding the uneven and incomplete spraying of the moisturizing water by a single rotating seated spraying head. This mechanism enables the concrete wall curing spraying device to have the function of multi-angle adjustment, and the multiple rotating seated spraying heads cooperate with each other to perform comprehensive and uniform curing spraying on the building concrete inner wall, effectively improving the effect of concrete spray curing.

[0027] 2. Through the provided sprinkler mechanism, electric regulating valve and PLC controller, when the angles of multiple rotating seated sprinkler heads are completely positioned, multiple rotating seated sprinkler heads are connected in series to the water outlet of the electric regulating valve through multiple PVC soft water pipes, and the water inlet of the electric regulating valve is connected to the permanent combined fire hydrant in the building through the PVC soft water pipe. Then the PLC controller controls the electric regulating valve to open, so that the water in the permanent combined fire hydrant in the building is transported to the rotating seated sprinkler heads adjusted at various angles through the PVC soft water pipe. The rotating seated sprinkler heads spray water onto the inner concrete walls of the building. Through sufficient water supply, the surface of the inner concrete walls of the building is moistened, and the cement particles in the inner concrete walls of the building can be cleaned. The particles provide sufficient hydration reaction conditions. At the same time, the PLC controller controls the electric regulating valve to start spraying and curing for 5 minutes every 2 hours, so as to provide continuous and reliable hydration reaction conditions for the concrete, and no manual operation is required. This mechanism enables the concrete wall curing spray device to have the function of automatic spraying and curing in small quantities and multiple times, which can improve the timeliness of spraying and curing of the inner walls of building concrete, and provide continuous and reliable hydration reaction conditions for the concrete, and try to avoid the cracking of the inner walls of building concrete due to inadequate spraying and curing. It can not only improve the effect and intelligence of the curing of the inner walls of building concrete, but also reduce the labor intensity of the staff, and improve the efficiency and convenience of spraying and curing of the inner walls of building concrete.

[0028] 3. Through the spray observation mechanism, when the concrete wall maintenance spray device is in use, the SIM card wireless camera can also remotely shoot the maintenance spray site image and transmit it back to the control room of the construction project. The SIM card wireless camera can rotate 360 ​​degrees freely to shoot, ensuring that the staff can remotely and comprehensively understand the situation of the maintenance spray site and monitor the effect of the maintenance spray of the building concrete wall. At the same time, the PLC controller also controls the cleaning component to clean the water stains on the surface of the glass cylinder to ensure the clarity of the picture taken by the SIM card wireless camera. The glass cylinder can also protect the protective cover of the SIM card wireless camera. This mechanism enables the concrete wall maintenance spray device to have the function of online monitoring, which can monitor in real time whether the on-site automatic spray maintenance equipment is operating normally, reducing the workload of manual inspections.

[0029] 4. Through the provision of a concrete hardness detection mechanism and auxiliary mechanism, the PLC controller controls the concrete hardness detection mechanism and auxiliary mechanism to automatically detect the hardness of the building concrete wall within 2 minutes before each curing spraying of the building concrete wall. At the same time, the electronic concrete hardness rebound tester can send the detected hardness value to the PLC controller in the form of an electrical signal. The PLC controller can control the opening of the electric regulating valve accordingly according to the surface hardness of the building concrete wall. That is, as the curing spraying of the concrete wall curing spray device is prolonged, the surface hardness of the building concrete wall gradually increases. This means that the degree of cement hydration reaction is already high, and most of the cement particles that can participate in the reaction have completed hydration or the hydration rate has become very slow. At this time, the need for external water replenishment is not as urgent as in the early stage. Accordingly, the amount of curing water sprayed can be appropriately reduced, that is, the purpose of saving water resources is achieved. Therefore, the PLC controller controls the opening of the electric regulating valve to gradually decrease. This mechanism enables the concrete wall curing spray device to have the functions of automatic concrete hardness detection and automatic adjustment of curing spray water flow, thereby improving the effect of curing spraying and enabling the concrete wall curing spray device to save water resources.

The above-mentioned power-on equipment and electrical connections are prior art and are well known to those skilled in the art and will not be repeated here.

[0045] The operating principle of the present invention is now described as follows: When the inner concrete wall of a building needs to be cured after demolding, first, a corresponding number of concrete wall curing spray devices are selected according to the position and area of ​​the inner concrete wall of the building, and the concrete wall curing spray devices are positioned and installed at the inner concrete wall of the building that needs to be cured. Specifically, the outer cylinder 1 is placed vertically, and the base 4 is inserted into the block 3 at the bottom end of the adjusting screw 2, and the base 4 is rotated so that the bottom end of the adjusting screw 2 extends outward, and the outer cylinder 1 is pushed up in reverse. Finally, the base 4 contacts the ground of the building, and the top block 54 contacts the roof of the building, thereby achieving the purpose of positioning the outer cylinder 1. Then, multiple sprinklers are adjusted through the first connecting ring 71. After the adjustment is completed, the first positioning bolts 72 on the different spraying mechanisms 7 are rotated in sequence. The first positioning bolts 72 squeeze the outer cylinder 1 to fix each spraying mechanism 7. Then the side end of the connecting cylinder 75 is connected to the first connecting groove 714 through the first connecting rod 73, the first slider 74 and the first horizontal slide groove 76, and the purpose of horizontally arranging the connecting cylinder 75 is achieved. At the same time, the length of the extension rod 77 is adjusted. After the length of the extension rod 77 is adjusted, the limiting bolt 78 is rotated to limit it. Then the angle of the adjusting rod 712 on the threaded rod 710 is adjusted, and the spraying angle of the rotating sitting sprinkler head 713 at the top of the adjusting rod 712 is further adjusted to make The rotating seated sprinkler heads 713 in the multiple spraying mechanisms 7 cooperate with each other to spray the moisturizing liquid on the surface of the inner concrete wall of the building in a comprehensive and uniform manner, avoiding the situation where a single rotating seated sprinkler head 713 sprays the moisturizing liquid unevenly and incompletely. Then, after the angle of the rotating seated sprinkler head 713 of each spraying mechanism 7 is adjusted, the limiting nut 711 is rotated, and the limiting nut 711 squeezes the adjusting rod 712, and squeezes the adjusting rod 712 to the rubber anti-slip sheet 12. The friction force of the deformation of the rubber anti-slip sheet 12 and the squeezing force of the limiting nut 711 can ensure that the angle of the adjusting rod 712 can be maintained stably after adjustment. At the same time, the position of the second connecting ring 81 is adjusted. and height, and fixed by the second positioning bolt 82, and then the side end of the second electric push rod 85 is inserted into the second connecting groove 88 through the second connecting rod 83, the second slider 84 and the second horizontal slide 86, so that the second electric push rod 85 is arranged horizontally and the detection end of the electronic concrete hardness rebound tester 87 is close to the outer surface of the inner wall of the building. This mechanism enables the concrete wall maintenance spray device to have the function of multi-angle adjustment, and the multiple rotating seated spray heads 713 cooperate with each other to spray moisturizing water on the inner concrete wall of the building in a comprehensive and uniform manner, effectively improving the effect of concrete spray maintenance and improving the reliability of the concrete wall maintenance spray device;

[0046] After the multiple rotating seated sprinkler heads 713 are completely positioned at different angles, the multiple rotating seated sprinkler heads 713 are connected in series to the water outlet end of the electric regulating valve 11 through multiple PVC soft water pipes, and the water outlet end of the last rotating seated sprinkler head 713 in the series water circuit is sealed to avoid overflow and waste of spray water. The water inlet end of the electric regulating valve 11 is connected to the building's indoor permanent combined fire hydrant through the PVC soft water pipe, and water is supplied to the concrete wall maintenance sprinkler device through the indoor permanent combined fire hydrant. Then, at the initial stage of spray maintenance, the PLC controller 93 controls the opening of the electric regulating valve 11 to be fully opened, so that the water in the building's indoor permanent combined fire hydrant is transported to the rotating seated sprinkler heads 713 adjusted at various angles through the PVC soft water pipe. The rotating seated sprinkler heads 713 spray water onto the building's concrete inner wall. Through sufficient water supply, the surface of the building's concrete inner wall is moistened, and sufficient hydration reaction conditions can be provided to the cement particles in the building's concrete inner wall, thereby improving the building's concrete inner wall. The hardness of the body surface is improved, and cracking of the surface of the building concrete wall is avoided. In addition, the rotating seated sprinkler head 713 is affected by the water flow, and the nozzle end of the rotating seated sprinkler head 713 will also rotate, which can improve the comprehensiveness and uniformity of the spray curing of the building concrete wall. At the same time, in order to cope with the situation where the vertical state of the building concrete wall causes insufficient retention of spray water, the PLC controller 93 controls the electric regulating valve 11 to start spray curing for 5 minutes every 2 hours, so as to provide continuous and reliable hydration reaction conditions for the concrete, and no manual operation is required, saving time and effort. This mechanism enables the concrete wall curing spray device to have the function of automatic spray curing in small quantities and multiple times, which can improve the timeliness of spray curing of the building concrete wall, and can provide continuous and reliable hydration reaction conditions for the concrete, and try to avoid the cracking of the building concrete wall due to inadequate spray curing. It can not only improve the curing effect, but also reduce the labor intensity of the staff, and improve the efficiency and convenience of spray curing of the building concrete wall.

[0047] When the concrete wall maintenance spraying device is in use, the SIM card wireless camera 58 can also remotely shoot images of the maintenance spraying site and transmit them back to the control room of the construction project, and the SIM card wireless camera 58 can freely rotate 360 ​​degrees to shoot, ensuring that the staff can remotely and comprehensively understand the situation of the maintenance spraying site and monitor the effect of the maintenance spraying of the building concrete inner wall. At the same time, the PLC controller 93 also controls the first electric push rod 56 to move back and forth slowly. The first electric push rod 56 will drive the moving plate 57 and the SIM card wireless camera 58 to move back and forth slowly. This reciprocating motion will not interfere with the clarity of the image captured by the SIM card wireless camera 58. During the reciprocating motion of the SIM card wireless camera 58, the guide bolt 61 will be driven to move, and the rotating nut 62 will be driven to rotate. When rotating left or right, the rotating nut 62 drives the glass tube 52 to rotate through the U-shaped frame 63, the first bearing 51 and the second bearing 53. During the rotation of the glass tube 52, the rubber scraper 65 can scrape off water stains attached to the surface of the glass tube 52 to ensure the clarity of the image captured by the SIM card wireless camera 58. The glass tube 52 can also protect the protective cover of the SIM card wireless camera 58 to prevent the protective cover of the SIM card wireless camera 58 from being interfered with by water stains and causing unclear images. This mechanism enables the concrete wall maintenance spray device to have an online monitoring function, which can monitor in real time whether the on-site automatic spray maintenance equipment is operating normally, reducing the workload of manual inspections. In addition, the online monitoring structure also has a protective function, ensures the clarity of the monitoring image, and improves the reliability of the device.

[0048] During the first 2 minutes of each curing spraying of the building concrete inner wall, the second electric push rod 85 of the PLC controller 93 slowly extends and pushes the detection end of the electronic concrete hardness rebound tester 87 close to the surface of the building concrete inner wall. As the moving end of the second electric push rod 85 continues to extend, the detection end of the electronic concrete hardness rebound tester 87 is pushed back by the surface of the building concrete inner wall and retracts. When the detection end of the electronic concrete hardness rebound tester 87 is completely retracted, the elastic potential energy stored in the internal impact spring of the electronic concrete hardness rebound tester 87 is released and converted into kinetic energy of the heavy hammer. The heavy hammer hits the electronic concrete hardness rebound tester 87. The instrument 87 detects the end and transmits force to the concrete surface at the same time. Due to the different hardness of concrete, the energy absorbed is different. The greater the hardness, the more it absorbs, and the smaller the rebound kinetic energy of the hammer. On the contrary, the smaller the hardness, the less it absorbs, and the larger the rebound kinetic energy of the hammer. Then, the rebound value is converted into the rebound distance of the hammer, and finally the hardness of the concrete is calculated. In addition, the electronic concrete hardness rebound tester 87 will also send the detected hardness value to the PLC controller 93 in the form of an electrical signal. At the same time, the L-shaped bracket 91 also clings to the surface of the inner wall of the building concrete and squeezes the touch switch 92. After the button of the touch switch 92 is pushed back and squeezed by the surface of the inner wall of the building concrete, the touch switch 92 is pressed. The circuit is turned on and an electrical signal is sent to the PLC controller 93. The PLC controller 93 controls the second electric push rod 85 to move back according to the electrical signal, and completes the automatic detection of the hardness of the building concrete wall. The PLC controller 93 can control the opening of the electric regulating valve 11 according to the surface hardness of the building concrete wall. That is, as the curing spraying of the concrete wall curing spraying device is extended, the hardness of the building concrete wall surface gradually increases, which means that the degree of cement hydration reaction is already high, and most of the cement particles that can participate in the reaction have completed hydration or the hydration speed has become very slow. At this time, it is necessary to add water from the outside. The demand is not as urgent as in the early stage, so the amount of curing water sprayed can be appropriately reduced accordingly, that is, the purpose of saving water resources is achieved. Therefore, the PLC controller 93 controls the opening of the electric regulating valve 11 to gradually decrease, and the concrete hardness test at the same position each time can effectively avoid the interference of other factors, so that the change in concrete hardness can effectively reflect the effect of concrete curing spraying. This mechanism enables the concrete wall curing spraying device to have the functions of automatic detection of concrete hardness and automatic adjustment of curing spraying water flow, thereby improving the effect of concrete curing spraying and enabling the concrete wall curing spraying device to save water resources.
